As can be seen from the drawing of FIG. 1, the claimed system includes a central control center with a train dispatcher workstation (1) and distributed controlled points KP1, KP2, ..., KHN (5.1, 5.2, ..., 5.N).

The central control center includes interconnected automated place for the train dispatcher 3 (AWP-DSC), equipment room 4, a remote automated place for the leadership of the road and the compartment (not shown in the drawing).

In the hardware room 4 there are located interconnected servers 11 (FS) for storing operational and archive data, LAN extenders 12 (radar), which allow connecting several users to the external LAN via server 11 and a communication device, which is a modem, 13 ( M / D), an automated place for electricians on duty at repair and technological sections 14 (AWP-SHN) and a printer 15.

At the workplace of the train dispatcher 3 (ARM-DNTs) equipment is installed that contains personal computers of industrial design 16 (PCII) with alphanumeric 17 (ACC) and functional 18 (FC) keyboards, manipulators of the mouse type 19, liquid crystal video terminals 20, a printer 21 for printing a graph of executed traffic and other reporting documentation, a local area network extender 22 (radar), which allows connecting several users to a local area network, an installation for operational dispatch communication and train radio communication , telephone (not shown in the drawing). All devices that are part of the workplace of the train dispatcher are interconnected.

The equipment AWP-DSC and AWP-SHN are interconnected by the first internal local area network 23 (LAN) through the radar 12 and 22.

The central control point 1 is intended for receiving, analyzing and displaying real-time data on tele-signaling objects, real-time display, archiving and creating copies of the schedule of the executed movement, automated generation of an application for it for the previous and current days.

At the central control point 1, a normative and executed traffic schedule is generated and displayed with translation, indication and change of train numbers, as well as automatic assignment of a system number. In addition, the train movement is adjusted and the schedule field of the executed train movement is scaled, the current schedule indicators are automatically calculated, displayed and compared with the planned ones: local and technical speeds, local speed coefficient, average weight and average length of freight trains.

The train dispatcher is provided with operational and reference information on approaches to the station's stations, train decomposition, exchange at junctions, approaches of local cars at stations, abandoned trains, freight and passenger locomotives, as well as station performance for freight and train work.

In addition, regulatory dispatcher information (longitudinal profile, station technical and regulatory acts, telecontrol command tables, safety rules and emergency response procedures) is displayed to the train dispatcher, technological messages are recorded, dispatcher notes are entered and displayed on the schedule of the executed movement.

The train dispatcher can find any train by index and number, interact informatively with other central control points and the automated transportation management system (ASOUP).

The functions of the central control point 1 also include the organization of a dispatcher’s dialogue on the formation of orders, reception of control actions by the dispatcher, their analysis and transfer to distributed controlled points, automation of the monotonous actions of the dispatcher when setting complex routes, continuous monitoring of the health of distributed controlled points, registration and localization of equipment failures and organization of remote jobs and interaction with adjacent sites (automatic transfer of numbers Sled, published from the portion managed) based INTRANET networks.

As can be seen from the drawing of figure 1, each distributed controlled item (5.1, 5.2, ..., 5.N) contains many blocks of output telecontrol signals (RCP-TU) 8.1, 8.2, ..., 8.N, many blocks remote signal input signals (RCP-TS) 7.1, 7.2, ..., 7.N, many television signal input blocks (RCP-TI) 9.1, 9.2, ..., 9.N, redundant central control unit (RCP-C ) 6, two devices for communication (MS) 24 (communication modules). Each RCP-C unit 6 consists of a basic set 6.0 and a backup set 6.1, designed to replace the main set in case of failure of the main set 6.0.

The functions of the distributed controlled items 5.1, 5.2, ..., 5.N consist in collecting and transmitting to the central control point data on the status of technological control objects in sporadic, cyclic modes or upon request, as well as receiving, analyzing the transmission for the implementation of telecontrol commands, including those responsible.

Distributed controlled points (KP) 5.1, 5.2, ..., 5.N provide software execution and control of the implementation of route set logic, which does not require additional circuit solutions. In addition, it generates acknowledgment messages, monitors the technical condition of signaling devices, diagnoses system hardware and transmits this information to the central control station.

The information exchange between the central control point 1 and the distributed controlled points 5.1, 5.2, ..., 5.N is carried out by sending the central control point 1 telecontrol commands to the distributed controlled points and transmitting the distributed controlled points to the central control point 1 of information (tele-signaling and telemetry ) about a change in the state of objects of control.

Telecommands are transmitted sporadically as needed. The tele-signaling signals of the vehicle and the telemetry of the TI are transmitted in several ways: when there is a change in the state of the controlled object (sporadically), if there are no changes in the state of the controlled objects during a given time interval (cyclically) and upon request from the central control center.

All information from the central control point to the distributed points and from the distributed points 5.1, 5.2, ... 5.N to the central control point 1 is transmitted via communication channels of the external local area network 2 through the corresponding communication modules 24 (MS).

Blocks RKP-TU, RKP-TS, RKP-TI provide pairing of the redundant central control unit of the distributed controlled point with the station automation and communication devices.

The central control unit 6 of each distributed controlled point 5.1., 5.2, ..., 5.N provides interaction via an external local area network 2 of this point with a central control point 1 and with a neighboring distributed controlled point, as well as provides interaction with RCP-TU units , RCP-TS and RCP-TI on the internal, local area network 25. Moreover, in a particular embodiment, the internal local area network is a two-wire, local area network.

Each RKP-TU 8.1, 8.2, ..., 8.N unit is designed to turn on no more than 8 control relays according to the telecontrol commands of the train dispatcher.

RKP-TS 7.1, 7.2, ..., 7.N blocks are intended for the input of controlled signals. One RCP-TS unit allows you to process no more than 20 signals. The number of blocks is determined by the number of signals.

RKP-TI 9.1, 9.2, ..., 9.N blocks are intended for input of analog signals: voltage in a rail circuit, input supply voltages, etc. in accordance with the project. One RCP-TI unit allows you to process no more than 12 telemetry signals. The number of blocks is determined by the number of signals.

In the claimed system KP1, KP2, ..., KPN are mounted on the cabinets of electric centralization (EC) of the respective stations.

In contrast to the known analogues with a centralized arrangement of equipment, in which the central control unit, remote control signal output units, telealarm signal input units and telemetry signal input units are made as a single module (located in a cabinet), in the claimed system the central control unit 6, signal output units telecontrol 8.1, 8.2, ..., 8.N, signal input blocks for television signals 7.2, ..., 7.N and signal input blocks for telemetry signals 9.1, 9.2, ..., 9.N are made in the form of separate modules that are placed both in free places one cabinet, and in the free places of many cabinets. At the same time, the objects of control and management are also located on the cabinets.

This arrangement of blocks and communication lines allows you to more fully use the available space on the cabinet, and reduce the consumption of the installation wire and cable interstate connections.

In addition, the modular design of RKP-TS, RKP-TU and RKP-TI blocks allows you to add the required number of RKP-TS, RKP-TU and RKP-TI blocks to the control box without the need to expand the cabinet dimensions (with centralized equipment placement), because . these blocks are located in free spaces of the cabinet and do not occupy a large volume in comparison with the known module on which the central control unit, RCP-TS, RCP-TU and RCP-TI are made.

We now consider the structure and operation of the RCP-Ts block.

As can be seen from the drawing of figure 2, the RCP-C unit contains, as already mentioned above, the main set 6.0 and the backup set 6.1, and also contains a diagnostic module (MD) 6.2, which are connected to each other by their inputs and outputs using a control line and tires (in the drawing combined in one line 6.3).

Both sets 6.0 and 6.1 have identical software, but at each moment of time only one of them (primary) is active and performs control functions, and the other (backup) is passive and performs only tracking functions. Such a construction of the RCP-C 6 unit provides shock-free switching of sets in case of failure, which allows, practically, not to lose control and management of the facility. To facilitate the maintenance of RCP-C 6 at the facility, a diagnostic module is included in it, which allows in the field to perform a functional check of the RCP-TU and RCP-TS blocks and reprogram the address of any block.

Each of the sets of the backup central control unit RCP-C consists of a control module (MU) 26 and a communication module (MS) 24.

The control module 26 contains a single-chip electronic computing machine (OEWM) 29, read-only memory (ROM) 28, random access memory (RAM) 30, sequentially reprogrammable read-only memory (EPROM) 31, an indication device (MI) 32, a reset device ( US) 33, display device (UO) 34, input-output buffer (IWV) 35, input device (UV) 36, matching device with local area network (USL) 37, temperature sensor (T) 38, time counter (CB) 39 , interface conversion device (UP) 40, device for controlling said set (OSU) 41 and a voltage converter (PN) 42.

The communication module 24, as shown in the drawing of figure 2, contains an interface converter (P232) 43, a single-chip electronic computer (OEWM) 44, random access memory (RAM) 45, read-only memory (ROM) 46, sequential reprogrammable read-only memory a device (PROM) 47, a reset device (US) 48, an indication device (UI) 49, a modulator (M) 50, a demodulator (DM) 51, a matching device with a communication channel (USKS) 52, and a communication channel switching device (UKKS) 53 .

Diagnostic module 6.2, as shown in FIG. 2, contains a voltage stabilizer (CH) 54, a key (K) 55, a device for converting a serial interface to a parallel interface (UP) 56, a single-chip electronic computer (OEWM) 57, an indication device (UI) 58, serial reprogrammable read-only memory (EPROM) 59, output matrix (MB) 60, matching device with local area network (USLS) 61 and matching device (US) 62, designed to coordinate the output unit of the telecontrol signals with OEVM 5 7.

In the diagnostic mode, the RCP-TS, RPK-TU blocks are connected to the diagnostic module 6.2 in turn. In this case, when connecting the RCP-TU unit, its output is connected to the input of the DC 62 (as shown in figure 2), and the input-output of the RCP-TU unit, to which the internal local area network 25 is connected in normal operation, is connected to the internal LAN diagnostic module 6.2. When connecting the RCP-TS block to the diagnostic module 6.2, the input of the RCP-TS block is connected to the output of the output matrix, and the input-output of the RCP-TS block, to which the internal local area network 25 is normally connected, is connected to the mentioned internal local network of the diagnostic module .

In each distributed controlled point KP1, KP2, ..., KPN, the RKP-Ts 6 block is designed to control the RKP-TS 7.1, 7.2, ..., 7.N, RKP-TU 8.1, 8.2, ..., 8 blocks .N and RKP-TI 9.1, 9.2, ..., 9.N, which are part of the corresponding clause KP1, KP2, ..., KPN and for the organization of digital communication with the central control center (1). In addition, each mentioned RCP-C is used to build aggregate complexes of automated control systems based on RCP tools. Communication of the RCP-C 6 unit with the RCP-TU 8.1, 8.2, ..., 8.N, RCP-TS 7.1, 7.2, ..., 7.N and RCP-TI 9.1, 9.2, ..., 9 blocks .N in each set is carried out via an internal local area network 25, consisting of a PWS cable (shielded twisted pair cable). The principle of signal transmission over the internal LAN 25 is bipolar pulse modulation (coding with a return to zero).

Voltage converter 42 is a converter that, with an input voltage of +24 V from an external power source, outputs ± 12 V and +5 V at its outputs. Converter 42 provides +12 V with a voltage of 37, 40 and 43, and a supply voltage of +5 In all other circuits of the control module 26 and the communication module 24.

In the control module 26 of each set 6.0, 6.1, the OEWM 29 is connected by an 8-bit data bus with ROM 28, RAM 30 and BVV 35.

OEVM 29 implements the following functions:

- reception, processing and transmission of commands and messages;

- the formation of messages about the state of the object and internal diagnostics and transfer of the latter to the communication module 24 through UP 40;

- continuous interrogation of RKP-TS and RKP-TU blocks through USLS 37.

ROM 28 is intended to store a program that implements all the functions of the RCP-C. RAM 30 is designed to store the current state of objects of control and management.

BVV 35 is a register through which the OEWM 29 is connected to the display device UO 34. UO 34 is designed to display technological information, as well as the modes and status of the RCP-C, and is a liquid crystal alphanumeric indicator, consisting of 4 lines of 20 characters in each. The indicator is controlled via a 4-wire data bus.

OEVM 29 through BVV 35 scans the input device UV 36, which is a matrix keyboard 4 × 4 with 16 keys. HC 36 is designed to control RCP-C 6, set the modes of its operation, diagnose all blocks, enter digital information that is displayed on the display device UO. HC 36 consists of 16 keys representing a 4 × 4 matrix, of which 10 are digits, 4 are navigation keys, one is input confirmation and one key is reset.

OEPM 29 is connected to the EPROM 31 with a two-wire I ² C bus. The EPRM 31 is used to store the address of the control unit, a list of telecontrol commands, as well as a formalized description of the structure of the station.

UI 32 allows you to visually evaluate the operation of the module. To indicate the operating modes of the module, 3 LEDs are installed: green - “set active”, yellow - “set passive” and red - “alarm”. Management of LEDs is carried out by OEVM 29.

Communication OEVM 29 with USLS 37, as shown in the drawing of figure 2, is carried out by means of a communication line consisting of two wires (reception and transmission). The two outputs of the OEWM 29, to which the USSL 37 is connected, are serial input-output ports and are configured (programmed) for universal serial asynchronous reception and transmission (USART).

USLS 37 converts pulses of 2 μs duration, amplitude up to 12 V, coming from internal local area network 25, to the TTL level (transistor-transistor logic, logic level “0” = from 0 V to 0.4 V, logic level “1” = from 2.4 V to 5 V) for the OEVM 29 when receiving, and vice versa during transmission. USLS 37 is based on RS-flip-flops (not shown in the drawings), while the pulse transformer, which is part of the USLN, galvanically decouples the unit from the internal local area network 25. In addition, USLS 37 performs the function of protecting against network overloads.

The temperature sensor (thermometer) (T) 38 is designed to measure temperature with an accuracy of 0.5 ° C and transmit the measured value to the OVM 29 via a 3-wire serial interface.

The time counter (“Time Service”) CB 39 is also connected to the OEVM 29 via a 3-wire serial interface and is designed to track time (hours, minutes and seconds) and the current date (year, month and day).

The reset device (US) 33 resets the OEVM 29 when the watchdog WDT timer, which is part of the US 33, is triggered after power is turned on or when the reset button is pressed.

The UP 40 interface conversion device consists of a dual universal asynchronous transceiver (DUART) and RS-232 and RS-485 interface buffers (not shown in the drawings).

The RS-232 buffer is intended for organizing communication between the control module 26 and the communication module 24 through P232 (43) of the module 24.

The RS-485 buffer is necessary for organizing the exchange of information between the control module 26 of the main set 6.0 with the control module 26 of the backup set 6.1, as well as for organizing the exchange of information between the control module 26 of set 6.0 (or set 6.1 in case of failure of set 6.0) and the diagnostic module 6.2. Information exchange between module 26 and module 6.2 is carried out via bus 6.3.

The control unit of the UUK 41 kit is designed to turn off the power of the neighboring backup set 6.1 in case of failure of the 6.0 set. Disabling kit 6.0 is as follows.

OEVM 29 of the control module 26 of the set 6.0 sends a signal to the УУК 41, from which the signal through the bus 6.3 gets to the УУК 41 of the control module of the set 6.1, which (УКК) turns off the PN 42 of the set 6.0 and gives the control signal to the converter PN 42 of the set 6.1, upon receipt of which PN 42 supplies power to all the units included in the kit 6.1.

In the communication module 24 of each set 6.0, 6.1, the OEPM 44 is connected by an 8-bit data bus with ROM 46 and RAM 45.

The indication device UI 49 in the communication module consists of 7 LEDs that indicate the following signals and conditions:

- state of the relay K1 (inclusion of the transmitter in the communication channel);

- state of relay K2 (inversion relay);

- issuance of synchronization (INF);

- hardware control of the presence of a carrier (CD);

- message reception (PRM);

- message transmission (PRD);

- modem error (ERR).

The P232 43 interface converter, as already noted above, is necessary for organizing communication between the OVM 44 of the communication module 24 and the OVM 29 of the control module 26 over the serial channel.

The modulator (M) 50 converts the byte received on the parallel bus from the OEWM 44 into an analog signal of the V.29 protocol. From the output of the modulator, the signal is supplied to the matching device with the communication channel 52.

The coordination device with a communication channel (USKS) 52 is designed to coordinate signals with communication lines and consists of fuses, resistances, matching transformers, protective zener diodes and buffer operational amplifiers (not shown).

USKS 52 with its input-output through the switching device of the communication channels 53 is connected to the communication channel of the external local area network 2.

The communication channel switching device (UKKS) 53 is intended for switching communication channels if it is necessary to organize an inversion or bypassing. UKKS 53 is built on a relay. Relays are controlled by OEVM 44 outputs via optocouplers.

The received signal from external LAN 2 also passes through UKKS 53, USKS 52 and is supplied to demodulator 51. DM 51 performs the functions of converting the analog signal of protocol V.29 received from external LAN 2 into digital form and generating bytes from bits. For each received byte of information, an interrupt is generated in OVM 44. The interrupt request is removed after reading a pleasant byte of OVM 44 through the parallel bus. From the received bytes, the OEVM 44 generates a message that transmits to the control module 26 through the P-232 interface converter (43).

In the communication module 24, the OEVM 44 is connected to the EPROM 47 with a two-wire I ² C bus. The EPROM 47 is used to store the address of this control unit (5.1, 5.2, ..., 5.N), the transmission level, as well as the configuration of the communication line.

The reset device (US) 48 is designed to reset the OEWM 44 by the control module 26 or when the watchdog WDT timer, which is part of the US 48, is triggered (not shown in the drawing).

In Diagnostic module 6.2, the voltage stabilizer CH 54 converts the +24 V voltage from an external power source through K 55.

CH 55 consists of two stabilizers for +12 V and +5 V. The voltage stabilizer 54 provides USLS 61 of the diagnostic module with a supply voltage of + 12V, and OEVM 57, PPZU 59, USLS 61, UI 58, UP 56 and US 62 of the diagnostic module 6.2 - supply voltage +5 V.

The two OEPM 57 outputs to which the USSL 61 connects are serial I / O ports and are configured (programmed) for universal serial asynchronous transceiver (USART).

OEVM 57 implements the following functions:

- reception and transmission of commands and messages from the RS-232 and RS-485 interfaces;

- interaction with the tested unit over the network;

- submission of test signals to the input of the RCP-TS unit;

- verification of the output signals of the RCP-TU unit.

USLS 61 converts pulses with a duration of 2 μs, amplitude up to 12 V, coming from the local network, into the TTL level for OEVM 57 when receiving, and vice versa during transmission. USLS 61 is made on the basis of RS-flip-flops, and the pulse transformer, which is part of USLS 61, galvanically disconnects the unit from the local network (not shown in the drawing).

The output of USLS 61 is connected to two NMSh1 sockets (where the tested RKP-TS, RKP-TU blocks are installed).

OEVM 57 is connected to EEPROM 59 with a two-wire I ² C bus. EEPROM 59 is designed to store the constants of an analog-to-digital converter (ADC).

UI 58 consists of 2 LEDs indicating the presence of power and the performance of test functions.

The interface conversion device UP 56 is designed to convert a serial interface to a parallel interface and consists of an RS-485 interface buffer through which the diagnostic module ОВМ 57 receives commands from control modules 26 and controls the key K (55), which switches the power supply to the diagnostic module.

Upon receipt of the enable signal of the diagnostic module 6.2, UP 56 turns on the key K (55) and the supply voltage from an external source goes to CH 54 and MB 60, i.e. module 6.2 is activated.

When checking the RKP-TS block in the diagnostic mode of the OVM 57 of module 6.2, it controls the output matrix 60, which alternately supplies the voltage of the station battery (external power source) to all the inputs of the tested RKP-TS block. Test results are transferred to the 6.0 management module (or module 6.1, if module 6.0 is out of order).

In the diagnostic mode, when checking the RKP-TU unit, module 6.2 must check the correspondence of the output voltage value with each output of the RKP-TU unit to a predetermined minimum value at a given load. The role of the load and the coordination of the amplitude of the signals of the RKP-TU output unit for measurement are performed by the matching device 62. The voltage is measured by the internal ADC of the OEVM 57. The measurement results of the OVM 57 are transmitted to the 6.0 control module (or 6.1 if the 6.0 module is out of order) via bus 6.3.

The output matrix 60, as shown in the drawing of FIG. 11, contains nine keys (KC1, KS2, KS3, KS4, KS5, KG1, KG2, KG3, KG4) and twenty decoupling diodes (TC01, TC02, .... TC20).

The control inputs of nine keys (KS1, KS2, KS3, KS4, KS5, KG1, KG2, KG3, KG4) are supplied with control signals from the OEWM 57 of the diagnostic module 6.2, while the control inputs of the keys are the input of output matrix 60 to which the corresponding output is connected OEWM 57. From the output of the K 55 key, +24 V is supplied to the inputs of all nine keys, while the inputs of all nine keys are the input of the output matrix, which is supplied with power from the key of the diagnostic module.

The output of the KC1 key is connected to the inputs of the first five decoupling diodes TC01, TC06, TC11, TC16, the output of the second key KC2 is connected to the inputs of the following five decoupling diodes TC02, TC07, TC12, TC17, the output of the third key KC3 is connected to the inputs of the following five decoupling diodes TC03, TC08, TC13, TC18, the output of the fourth key KC4 is connected to the inputs of the following five decoupling diodes TC04, TC09, TC14, TC19, the output of the fifth key KC5 is connected to the inputs of the remaining five decoupling diodes TC05, TC10, TC15, TC20. The outputs of all decoupling diodes TC1, ..., TC20 and the outputs of KG1, KG2, KG3, KG4 are combined and are outputs of the output matrix 60.

The messages exchanged between the RCP-C 6 module units satisfy the requirements of the IEC standard FT3 code format. This frame consists of the following components: the frame header and the frame body. The header is the initial code block of the frame, which includes the frame length field L, address field A, data control field C, data field and control field.

Field length L - usually contains one byte and indicates the number of bytes of data D in the information blocks of the frame. The value of L ranges from 0 to 255.

Address field A, when transmitting a message from a transmitting station to a receiving station, contains the address of the receiving station. When transmitting a message, the answering station contains the address of this station. The number of bytes of the address field depends on the number of subscribers in the network. The address byte corresponding to the smallest number is transmitted first.

The control field C contains information about the direction of the message and the functional purpose of the frame.

The checksum field is generated using CRC-16 coding based on the generating polynomial:

P (x) = x ¹⁶ + x ¹³ + x ¹² + x ¹¹ + x ¹⁰ + x ⁸ + x ⁶ + x ⁵ + x ² +1

in accordance with GOST R IEC 870-4-93.

Information is transmitted sequentially in asynchronous mode. Transmission to the line begins with the least significant bit, i.e. D0 D1 ... D6 D7. The transmitted byte begins with a start bit (transmitted with a logical zero), and ends with a stop bit (transmitted with a logical unit).

The following messages are used in the protocol for exchanging the RCP-C block with the RCP-TS, RCP-TU and RCP-TI blocks on the internal local network 25 of the distributed controlled point KP1, KP2, ..., KPN:

a) from RCP-Ts1:

1) Team - “Request for changes”;

2) The command is “Status Request”;

3) Team - “Diagnostic Request”;

4) The command is “Turn on the key for 10 seconds”;

5) Command - “Give out voltage”;

6) Command - “Issue the number of the last included key and generator”;

7) Command - “Request for settings”;

8) Team - “Pre-programming”;

9) Team - “Working Programming”;

10) Team - “Block Restart”.

b) from RCP-TS:

1) The answer is “No Change”;

2) The answer is “Information on changes”;

3) The answer is “Information on the state of the block”;

4) The answer is “Diagnostic information”;

5) The answer is “Team Accepted”;

6) The answer is “Settings”.

c) from RCP-TU:

1) The answer is “No Change”;

2) The answer is “Diagnostic information”;

3) The answer is “Team Accepted”;

4) The answer is “The number of the last included key and generator”;

5) The answer is “The command is running”;

6) The answer is “Settings”.

Block RCP-C 6 sequentially sends the command “Request for changes” to all blocks of RCP-TS 7.1, 7.2, ..., 7.N in order to detect changes in the state of controlled objects. If there are no changes from the moment of the last communication session, the block transmits a response - “No changes”. If 5 or fewer changes have occurred, the block transmits a response that indicates:

- total number of changes;

- input number of the state-changed;

- A new login state, one of the following:

“10” - at the input logical level 1;

“01” - at the input the logic level is “0”;

“11” - blinking signal at the input.

If more than 5 changes have occurred, the unit transmits a response with information on the status of all monitored signals, which indicates the current status of all inputs.

After interrogating all RCP-TS 7.1, 7.2, ..., 7.N blocks, the RCP-C 6 block sends a status request to one RCP-TS block. Upon receipt of the request, the RCP-TS unit transmits a response with information about the status of all monitored signals.

Upon receipt of the message “Diagnostic request” by the RCP-TS unit, the RCP-TS block will transmit a response with diagnostic information that contains:

1) information about fatal errors - the column number of the output matrix 60, which has:

- short circuit;

- breakage of diagnostic zero;

- breakage of the diagnostic unit.

2) information on non-fatal errors:

- checksum error counter;

- counter of buffer overflow errors in reception and format mismatch;

- counter external restart OEVM 63 block RCP-TS;

- counter restart OEVM 63 block RCP-TS from the internal watchdog timer.

If fatal errors are detected on any request, the RCP-TS unit will respond with diagnostic information.

The RCP-TS unit responds to the request “Settings” with a message stating:

- software version number;

- date of installation of the address, for example, “11.12.1998”;

- address setting time, for example, “07.45”.

Blocks received from the factory have an address of 254 (0xFE). To change the block address, it is necessary to reprogram the block address, which is carried out in two stages using the “Pre-programming” and “Working programming” commands. The “Pre-programming” command contains:

- from the block;

- the date the address was set, for example, “12/11/1998”;

- address setting time, for example, “07.45”.

The RCP-TS unit (RCP-TU, RCP-TI) responds to this command with the message “Command accepted”. Next, the RCP-C block sends a “Working Programming Command”. Having received it, the RCP-TS unit (RCP-TU, RCP-TI) responds with a message - “Command accepted”, but with a new address.

After polling all the RCP-TS blocks, the RCP-C block sends a change request to one RCP-T block. Having received the request, the RCP-TU unit transmits a response - “No changes”. In this way, the operability of the unit and the communication line is checked.

After receiving the telecontrol command via communication line 2, the RCP-C block issues a command to the RCP-TU block “Turn on the key for 10 seconds”, the RCP-TU block transmits a response “Command accepted” and turns on the key K1 131 (or K2 132), the number of which is indicated in a team. Next, the RCP-C unit sends a command “Output voltage”, which indicates:

- numbers of activated outputs (it is possible to turn on all outputs simultaneously);

- team implementation time (from 40 ms to 10 s).

Having received the command, the RCP-TU unit transmits the response “Command Accepted” and issues voltage at the indicated terminals.

After the time the command is completed, the RCP-C block sends a request “Issue the number of the last included key and generator”, to this request the RCP-TU block transmits information about the key numbers (K1 131 or K2 132) that were included when the last command and numbers were executed outputs to which voltage was issued.

After 10 seconds from the moment the “Turn On Key” command was accepted, if the second command to issue voltage is not followed, the K1 131 (or K2 132) key will be turned off, which eliminates the false appearance of voltage at the outputs.

When the control module 26 interacts with the communication module 24 of a set of 6.0 or 6.1, the following messages are used:

1) Messages transmitted from module 26 to module 24:

- modem reset command;

- request for status byte;

- command for measuring the level of the input signal;

- command - set the level of the output signal;

- MS address setting command;

- command - turn on relay K1;

- command - turn off relay K1;

- command - enable relay K2;

- command - turn off relay K2;

- request statistics of the N-th group.

2) Messages transmitted from module 24 to module 26:

- willingness to receive;

- value of the set output signal level;

- confirmation of the address setting command;

- a message about the current state of the relay;

- statistical message of the N-th group.

Diagnostic module 6.2 works as follows.

When checking the RKP-TS unit, module 6.2 alternately connects the voltage of the station battery (external power supply) to all the inputs of the tested RKP-TS unit. Test results are transmitted to control module 26.

When checking the RKP-TU block, the module must check the correspondence of the voltage output value with each block output to the preset minimum value. The voltage is measured by the internal ADC of the OEVM 57. The measurement results of the OEVM 57 are transmitted to module 26.

When the control module 26 interacts with the diagnostic module 6.2, the following messages are used:

1) Messages sent from module 26 to module 6.2:

- Request for measurements;

- Command - perform calibration;

- Team - switch to the testing mode of RCP-TS blocks;

- Team - switch to the testing mode of RCP-TU blocks;

- Set the columns and rows of the matrix of the vehicle;

- Relay the message from the local RCP network;

- Search for a module;

- Perform automatic testing of RCP-TS;

- Perform automatic testing of RCP-TU.

2) Messages sent from the diagnostic module 6.2 to the control module 26:

- The result of measuring the voltage at the outputs of the RCP-TU;

- The result of measuring the voltage of the station battery;

- The command is accepted, it is being executed;

- The result of the module search (address of the responding module);

- The result of the test RKP-TU indicating the faulty output;

- The test result of the RCP-TS indicating the faulty input.

Consider the structure and operation of the RCP-TU blocks.

RKP-TU 8.1, 8.2, ..., 8.N blocks are intended for the implementation of telecontrol signals (activation of control relays) coming from RKP-Ts via an internal local area network 25. Each of these blocks allows connecting 8 control relays. Communication with RKP-Ts 6 with RKP-TU 8.1, 8.2, ..., 8.N is carried out via the internal local area network 25, presented in the form of a PPS cable (shielded twisted pair cable). The principle of signal transmission in a local network, as mentioned above, is bipolar pulse modulation (coding with a return to zero) - pulses with a duration of 2 μs, an amplitude of up to 12 V, and a pulse repetition rate of 28800.

The structure of the RKP-TU block, as shown in the drawing of Fig. 4, includes the following elements: voltage stabilizer (SN) 72, sequential reprogrammable read-only memory (EPROM) 73, matching device with local area network (USLS) 74, indicating device (UI ) 75, single-chip electronic computer (OEWM) 76, the first (PP1) 77 and second (PP2) 78 power control devices for energy converters, the first (TU1) 79, the second (TU2) 80, the third (TU3) 81, the fourth ( TU4) 82, fifth (TU 5) 83, sixth (TU6) 84, seventh (TU7) 85 and eighth (TU8) 86 the role of voltage at the telecontrol outputs of the telecontrol signal output unit, ten galvanic isolation elements (respectively EGR 0 - EGR 8) (87, 88, 89, 90, 91, 92, 93, 94, 95, 96), the first (97) and the second (98) output modules.

The first output module 97 contains four energy converters (respectively PR1, PR2, PR3, PR4) (99, 100, 101, 102), four transformers (respectively T1, T2, T3, T4) (103, 104, 105, 106), four rectifiers (B1, B2, B3, B4) (107, 108, 109, 110), four filters (respectively F1, F2, F3, F4) (111, 112, 113, 114), key K1 (131).

The second output module 98 contains, like the first output module 97, four energy converters (respectively PR5, PR6, PR7, PR8) (115, 116, 117, 118), four transformers (respectively T5, T6, T7, T8) (119 , 120, 121, 122), four rectifiers (B5, B6, B7, V8) (123, 124, 125, 126), four filters (respectively F5, F6, F7, F8) (127, 128, 129, 130) , key K2 (132).

The stabilizer (CH) 72 provides the conversion of +24 V voltage from an external power source to +5 V and +12 V. The CH 72 consists of two stabilizers for +12 V and +5 V connected in series and provides the USL 74 with + 12 V, and ОЭВМ 76, ППЗУ 73, УСЛС 74 and other elements of the RKP-TU block, with the exception of filters, rectifiers and transformers, provides +5 V.

OEVM 76 implements the following functions:

- receiving commands from the local network;

- the formation of control pulses for the Converter;

- check for voltage at the outputs of the module;

- health check (diagnostics);

- writing and reading addresses from EEPROM 73;

- formation and transmission of diagnostic messages.

EPROM 73 is used to store the device address, date and time of programming. OEVM 76 is connected to the PRZU 73 two-wire bus GS. When starting up, OEVM 76 reads the address of the block, the date and time of programming. If necessary, OEVM 76 writes to the EEPROM 73 the new address and installation date.

EGR0 - ERG8 (87-96) are made on optocouplers and are designed for galvanic isolation between the OEVM 76 and energy converters PR1-PR8 (99-102, 115-118).

PP1, PP2 (77, 78) and TU1-TU8 (79-86) allow you to control the power of the converters and the voltage at the outputs 1-8 of the RCP-TU unit, while the control information is read in a matrix way (similar to the reading method in the RCP-unit TS, but without control “0” and “1”). The output out0 gives “1”, and the result is read from IN0, IN1.

Converters PR1-PR8 (99-102, 115-118) are controlled by an OEVM 76 and generate pulses with an amplitude of 24 V and a frequency of ~ 40 kHz. Converters are loaded on transformers T1-T8.

Transformers T1-T8 (103-106, 119-122) are designed to implement a “safe exit”, i.e. output voltage will be present only when the condition of the circuit elements of the converters PR1-PR8 (99-102, 115-118) is in good condition.

Rectifiers B1-B8 (107-110, 123-126) provide AC rectification after the corresponding transformers T1-T8 (103-106, 119-122). Rectifiers are made according to the bridge circuit.

Filters F1-F8 (111-114, 127-130) smooth the voltage at the respective outputs of the first and second output modules and, accordingly, the outputs of the RCP-TU unit and suppress the conversion frequency.

UI 75 consists of 3 LEDs - 2 green, indicating the reception and transmission of messages over the local network, and 1 red - to indicate the emergency status of the unit. UI 75 allows you to visually evaluate the operation of the unit when receiving and transmitting messages, when performing generation on each channel of the control unit, as well as in the event of emergency situations in the operation of the unit (the appearance of external disturbing voltages at the outputs of the control unit and reading the address from EPROM 73).

USLS 74 is intended for matching the local network signals with OEVM 76 signals. Communication OVM 76 with USLM 74 is carried out by means of a communication line containing two wires (reception and transmission). The two OEVM 76 pins, to which the USLS 74 connects, are serial I / O ports and are configured (programmed) for universal serial asynchronous transceiver (USART). USLS 74 converts pulses with a duration of 2 μs and an amplitude of up to 12 V, coming from the local network, into the TTL level for the OEWM 76 during reception, and vice versa during transmission. USLS is based on RS-flip-flops, and the pulse transformer, which is part of USLS 74, galvanically decouples the RKP-TU unit from the internal LAN 25.

When the command is executed (by the example of issuing voltage at the output 1 (output TU1) of the OEVM unit 76, it generates the UP1 signal to turn on K1 131 of the first output module through the first EGRO galvanic isolation element (optocoupler).

When the key K1 131 is activated, the voltage + 24 V from an external power source is supplied to the input of the control device PP1 77 and to the input of the converter PR1 99.

The voltage supply to the PR1 99 converter is controlled by OEVM 76 through the control device PP1 77.

Next, OEVM 76 begins to generate a sequence of control pulses with a frequency of 40 kHz, which, through the second galvanic isolation element EGR1 88, are supplied to converter PR1 99. From the output of converter PR1 99, 24 V pulses are supplied to transformer T1 103, from the output of which to rectifier B1 107, assembled from diodes on a bridge circuit. From the output of the rectifier In 1 107 signals are fed to the input of the filter F1 111.

In the present invention, each said filter is made in the form of a smoothing capacitor.

The output voltage from the output of the filter F1 111 goes to output 1 (output TU1) of the RCP-TU unit and to the input of the control element TU1 79, which opens when voltage appears on the output of the unit, and its opening, as already noted, is controlled by OEVM 76.

Similarly, the voltage is output at the outputs 2-4 (outputs TU2-TU4) of the unit. The voltage at the output of the unit 2 and at the input of the control unit TU2 80 appears when a signal is received from the second filter F2 112, to which the signal from the second rectifier B2 108 arrives, to the input of which the signal comes from the second transformer T2 104, the input of which receives the signal from the second Converter PR2 100, the inputs of which receive signals from the first key K1 131 and from the third galvanic isolation element EGR2 89. The voltage at the output of the 3 block and the input of the control element TU3 81 appears when a signal is received from the third filter F3 113, at which receives the signal from the third rectifier B3 109, the input of which receives the signal from the third transformer T3 105, the input of which receives the signal from the third converter PRZ 101, the inputs of which receive signals from the first key K1 131 and from the fourth galvanic isolation element EGR3 90. The voltage at the output 4 of the unit and the input of the control unit TU4 82 appears when a signal is received from the fourth filter F4 114, the input of which receives a signal from the fourth rectifier B4 110, the input of which receives a signal from the fourth transformer Ator T4 106, the input of which receives a signal from the fourth inverter 102 WP4 on signals from the first key K1 which receives inputs 131, and the fifth element 91 EGR4 galvanic isolation.

In the same way, the second output module 98 of the RKP-TU block is operated and the signals appear at the corresponding inputs of the corresponding control devices TU5-TU8 (83, 84, 85, 86) and at the outputs 5-8 (TU5-TU8) of the RKP-TU block . In this case, the signals at the outputs of the PR5-PR8 (115-118) converter blocks appear when the second key K2 132 is triggered and signals from the corresponding outputs of the EGR5-EGR8 galvanic isolation elements (92-96) are received. In addition, the converter PP2 78 from the second key K2 132 also receives +24 V from an external power source.

In this invention, PP1 77 and PP2 78 are optocouplers.

If the switch K1 131 is turned on and the voltage +24 V is present on the PR1-PR4 (99-102) converters, then the optocoupler in PP1 77 is open. Logical “1” with out0 through the open optocoupler falls into IN0 (if there is no voltage on the PR1-PR4 (99-102) converters, then the optocoupler is closed and IN0 = “0”). Change polled columns every 40 ms, i.e. after 40 ms, “1” is issued to the output out1, and “0” to the remaining out. If there is voltage at the output of TU1, then the optocoupler is open and also “1” with out1 goes to IN0. If closed (no voltage), then IN0 = “0”.

Let us now consider the operation algorithm of the signal output unit RCP-TU.

1. The reaction of the RCP-TU to “freeze” the microprocessor OEVM 76.

Under the hang in this invention refers to the following. “Hang” in the sense of stopping the change of the command counter, while the outputs remain a certain combination of “0” and “1”, and the absence of changes at the input of the transformer will lead to interruption of generation. “Hang” in the sense of uncontrolled “looping” when executing a separate section of program code.

“Looping” is possible only when performing a cyclic section of the program in the following cases:

- Failure to increase / decrease the current counter during the execution of the cycle;

- transformation of a conditional transition team into an unconditional;

- upon reaching the boundary of the cycle, completion signs are not set (flags: C - sign of overflow, Z - sign of zero).

When implementing the RKP-TU program code, the principle of replacing the cyclic sections of the program with linear ones is applied due to the repeated repetition of the codes executed in the cycle. To reduce the length of the program code, a subroutine call mechanism is used. In this case, to ensure control of the duration of the pulse generation at the input of the converter, a calculated input to the linear section consisting of only CALL commands is used.

The microcontrollers of the PIC16C6X family have a built-in WDT watchdog timer, which can only be turned off via the configuration bit set during programming. To increase reliability, it works from its own RC-generator. Using WDT allows you to control the correct implementation of the algorithm. In the event of any violation, the “recharge” of the WDT ceases, which leads to a hardware restart of the OVM 76.

Circuit solutions of the RCP-TU unit provide continuous monitoring of the voltage at the outputs of the unit. If a voltage appears at the output of the unit, then this voltage will be fixed by the OEVM 76 and a message will be sent indicating the presence of voltage. At the same time, the unit does not execute commands, but only responds to a diagnostic request and must be replaced by a working one.

2. The reaction of the RCP-TU to the violation of the protocol of exchange with the RCP-C 6.

The exchange protocol uses asynchronous (start-stop) transmission of bytes with a header of 2 bytes (0 × 05 and 0 × 64) and CRC 16 with a code distance of d = 6. The presence of the “start” and “stop” bits in each received byte is controlled by hardware.

Protocol violations:

- the command to control the voltage supply to the converter has not been completed;

- command sending is not completed - start the converter;

- the presence of distortion in the message.

If the message is lost, “turn on the key” will not be output voltage block, because no voltage will be supplied to the converters and the command will not be accepted for execution, followed by a diagnosis of the key not turned on.

If the message is lost, “give out generation” will not be output voltage block, because there will be no control action on the generators, the voltage from the converters will be removed after 10 s.

Using CRC 16 with d = 6 makes it possible to guarantee the detection of almost any errors in the received message. Only messages for which the received and calculated CRC-16 are the same are accepted for implementation.

3. The reaction of the RCP-TU when a failure is detected.

RCP-TU software allows you to monitor the following failures:

- the appearance of interfering voltage at the output in the absence of generation;

- uncontrolled operation or the inability to control the key to supply voltage to the converter;

- control of the code issued to the outputs of the block recorded in 4 different places of RAM OEVM 76 in different formats.

The detection of any failure in the RCP-TU block prohibits the execution of the command to turn on the keys and control generation at the input of the converter.

4. The execution of the generation command (see figure 5).

RCP-C 6 transmits two commands to RCP-TU. The first preliminary one - power is supplied to the converter, the second working one - sets the generation time and sets which outputs give voltage. Having received a preliminary command, OEVM 76 starts the timer for 10 s. After time, if a working command does not come, the supply voltage of the converters will be removed.

Upon receipt of the RCP-TU working command (see Fig. 5), in which the block address is the same, CRC16 = 0, the block type of the ОЭВМ 76 transcribes from the message the code of the necessary channels for generation (at which terminals to generate voltage) to the RAM ОЭВМ 76. В four different points of RAM OEVM 76 allocated cells K0, K1, K2, K3 (see table. 1).

). В ячейку К2 записывается значение ячейки К0 с переставленными тетрадями (K2=SWAP(K0)). В ячейку К3 записывается инвертированное значение К0 с переставленными тетрадями (K3=SWAP(

)). После записи в ячейки К0, K1, K2 и К3 устанавливаем флаг команды генерации и производим программирование необходимых каналов ОЭВМ 76 на вывод. В соответствии с требуемым временем генерации происходит смещение по таблице на соответствующую величину, которая определяет количество подпрограмм. После успешной отработки алгоритма выдачи напряжений сбрасываем флаг команды генерации, выключаем питание преобразователя, программируем на ввод каналы ОЭВМ 76 и осуществляем выход из программы.In the cell K0 is written the code of the numbers of the generators that issue the voltage (K0). The inverted value of the cell K0 (K1 =

) Cell K2 records the value of cell K0 with rearranged notebooks (K2 = SWAP (K0)). Inverted value К0 with rearranged notebooks (K3 = SWAP (

)). After writing to the cells K0, K1, K2 and K3, we set the flag of the generation command and program the necessary channels of OEVM 76 for output. In accordance with the required generation time, the table is shifted by the corresponding value, which determines the number of subprograms. After successfully working out the algorithm for issuing voltages, reset the flag of the generation command, turn off the power of the converter, program OEVM channels 76 for input, and exit the program.

4. Subroutine 10 millisecond meander generation (see Fig.6).

)+(

-SWAP(K1))=0) генерации в четырех различных точках ОЗУ ОЭВМ 76 (см. фиг.6). В случае выполнения всех четырех условий выполняется 450 элементарных пакетов генерации меандра. При не выполнении хотя бы одного из четырех условий: сбрасывается флаг команды генерации, выключается питание преобразователя и программируются каналы ОЭВМ 76 на ввод. Перед выходом из подпрограммы производится подпитка WDT.When entering the subroutine, it is checked: whether the generation command flag is set, whether there is control of the power supply of the converters, the absence of voltage at unused outputs and the coincidence of the position code ((SWAP (K0) ⊕

) + (

-SWAP (K1)) = 0) generation at four different points in RAM OEVM 76 (see Fig.6). If all four conditions are met, 450 elementary meander generation packets are satisfied. If at least one of the four conditions is not fulfilled: the flag of the generation command is reset, the power to the converter is turned off, and OEVM 76 channels are programmed for input. Before exiting the subroutine, the WDT is energized.

5. Elementary meander generation package (see Fig. 7).

When entering the subroutine (see Fig. 7), all conditions are checked:

1) There is no voltage at unused outputs.

2) There is power control of the converters.

3) The positional code of the channels for generation at four points of RAM matches.

If at least one of the three conditions is not met, the generation command flag is reset and the power to the converters is turned off.

If all conditions are met, we perform 1/2 the generation period and issue “0” into the necessary channels, perform 1/2 the generation period into the necessary channels “1”

Consider the structure and operation of the RCP-TS blocks.

The RKP-TS 7.1, 7.2, ..., 7.N remote signaling signal input signal blocks in each controlled point KP1, KP2, ..., KPN are designed to enter controlled signals and transmit them to RCP-Ts of the corresponding controlled point on the internal local network 25. RKP-TS block allows you to control twenty input signals with an amplitude of 24 V DC or AC voltage. The communication of blocks 7.1, 7.2, ..., 7.N in each distributed controlled point KP1, KP2, ..., KPM with RCP-C is carried out via the PWS cable (shielded twisted pair). The principle of signal transmission in the internal local area network is bipolar pulse modulation (coding with a return to zero) - pulses with a duration of 2 μs, an amplitude of up to 12 V, and a pulse repetition rate of 28800.

As can be seen from figure 3, each RCP-TC unit contains a control module 68 and an input module 69.

The control module 68 contains a voltage stabilizer 66 (CH), a serial flash programmable read-only memory 64 (EPROM), a single-chip electronic computer 63 (OEWM), an indication device 67 (UI), and a device for matching with a local area network 65 (USL).

Voltage stabilizer 66 converts +24 V voltage from an external power source to +5 V and +24 V. Voltage stabilizer 66 consists of two stabilizers for +12 V and +5 V connected in series and provides the USL 65 with +12 V supply voltage and ОЭВМ 63, ППЗУ 64, УСЛС 65 and УИ 67 with supply voltage +5 V.

OEVM 63 implements the following functions:

- receiving messages from the internal LAN 25;

- transmission of messages on the status of the inputs of the vehicle to the internal local area network 25;

- health check (diagnostics) of input module 69 (test readings of zeros and ones);

- writing and reading addresses from EEPROM 64.

USLS 65 is designed to coordinate the signals of the internal local area network 25 with the signals OEVM 63.

EPROM 64 is used to store the device address, date and time of programming. Data exchange is carried out on the I ² C bus.

UI 67 allows you to visually evaluate the operation of the RCP-TS block when receiving and transmitting messages, as well as in case of emergency situations in the operation of the RCP-TS block (errors in the diagnosis of input module 69, reading the address from EPROM 64).

Input module 69 of each RCP-TS block is made in the form of a matrix of size m × m, where m = 6, consisting of six columns (T0-T5) and six rows (10-15).

The matrix consists of galvanic isolation elements (70.1, 70.2, ..., 70.20) and elements of integrity control of I / O I / O of the computer (71.1, 71.2, ..., 71.16). The number of elements for monitoring the integrity of the inputs and outputs of the computer is less than the number of elements for galvanic isolation. In the particular case of execution in the input module, as shown in the drawing of FIG. 3, there can be 20 galvanic isolation elements (TC1, TC2, ..., TC20) and 16 elements of monitoring the integrity of the input-output OEVM.

TC1, ..., TC20 are made on optocouplers and carry out galvanic isolation of input circuits. Secondary optocoupler circuits are assembled according to the matrix input scheme.

Elements 70.1, ..., 70.20 and 71.1, ..., 71.16 are located in the matrix so that they form six rows and six columns of the matrix.

As can be seen from the drawing of figure 3, in the first column T0 of the matrix contains three elements of galvanic isolation TC1, TC2, TC3 (70.1, 70.2, 70.3) and three elements of integrity control (71.1, 71.2, 71.3), in the second column T1 of the matrix contains three isolation elements ТС4, ТС3, ТС6 (70.4, 70.5, 70.6) and three elements of integrity control (71.4, 71.5, 71.6), the third column Т2 of the matrix contains four isolation elements ТС7, ТС8, ТС9, ТС10 (70.7, 70.8, 70.9, 70.10) and two elements of integrity control (71.7, 71.8), the fourth column T3 of the matrix contains four galvanic elements isolation TS 11, TS12, TS13, TS14 (70.11, 70.12, 70.13, 70.14) and two elements of integrity control (71.9, 71.10), the fifth column T4 of the matrix contains three galvanic isolation elements TS15, TS 16, TS17 (70.15, 70.16 , 70.17) and three elements of integrity control (71.11, 71.12, 71.13), the sixth column T5 of the matrix contains three elements of galvanic isolation TC18, TC19, TC20 (70.18, 70.19, 70.20) and three elements of integrity control (71.14, 71.15, 71.16) .

As can be seen from the drawing of figure 3, in the first row I0 of the matrix, the elements are located in the following sequence: 71.1, 70.4, 70.7, 70.11, 70.15, 71.14, in the second row I1 of the matrix there are elements in the following sequence: 70.1, 71.4, 70.8, 70.12, 71.11, 70.18, in the third row I3 of the matrix there are elements in the following sequence: 70.2, 70.5, 71.7, 71.9, 70.16, 70.19, in the fourth row I3 of the matrix there are elements in the following sequence: 71.2, 71.5, 71.8, 71.10, 71.12, 71.15, the fifth row I4 of the matrix contains the elements in the following sequence: 70.3, 71.6, 70.9, 70.13, 71.13, 70.20, in the sixth I5 row of the matrix contains the elements in the following sequence: 71.3, 70.6, 70.10, 70.14, 70.17, 71.16.

OEWM 63 configures six lines of columns T0-T5 for output, and six lines of lines I0-I5 for input. At the intersections of columns and rows are monitored signals (TC1-TC20) and diagnostic signals “0” and “1” (diagnostic zeros and ones). Columns are scanned sequentially by setting a logical “1” on the column lines (T0-T5) and determining the level on the row lines (I0-I5). The scan time of each column is 20 ms, and the entire matrix - 120 ms. When scanning each column, the diagnostic signals “0” and “1” are checked, which guarantees the operability of the input matrix (OEVM inputs respond to “0” and “1”).

For example: when reading the signals of the line of the column T0, OEVM 63 sets the logical “1” (+5 B) on the line of the column T0, and on the lines of the columns T1-T5 logical “0” (0V) and reads the state of the lines of the lines I0-I5. At the same time, OEVM 63 checks the control “0” and “1”, i.e. I0 = “1”, and I3 = I5 = “0”. And besides this, OEVM 63 checks the information signals themselves (TC1-TC3). If 24 V is present at the input of TC1, the optocoupler is open and the logic level “1” passes from T0 to line I1 (signal on line I1 = “1”). If the voltage at the input of TC1 is 0V, the optocoupler is closed and the logic level “1” does not pass from T0 to line I1 (signal on line I1 = “0”). It is also carried out for other signals of the column line T0 (TC2, TC3).

OEVM 63 is connected to the EPROM 64 by a two-wire I ² C bus. At startup, the OEVM 63 reads the address of the block, the date and time of programming. If necessary, OEVM 63 writes to PISA 64 the new address and installation date.

UI 67 consists of 3 LEDs: 2 green, indicating the reception and transmission of messages over the local network, and 1 red to indicate the emergency state of the unit.

Communication OEVM 63 with USL 65 is carried out by means of a connection line containing two wires (reception and transmission) (in the drawing of figure 3, these two wires are also combined in one line). The two OEVM 63 pins to which the SLDS 65 connects are serial I / O ports and are configured (programmed) for universal serial asynchronous transceiver (USART).

USLS 65 converts pulses with a duration of 2 μs and an amplitude of up to 12 V, coming from the local network, into the TTL level for the OEVM 63 during reception and vice versa during transmission.

USLS 65 is based on RS-flip-flops, and the pulse transformer, which is part of the USLS 65, galvanically decouples the RKP-TS unit from the internal LAN 25.

The RCP-TS unit operates according to an algorithm consisting of a main cycle and two subprograms called by time interruptions.

The main cycle is as follows (Fig. 8).

In this cycle, the correct operation of the RCP-TS unit is checked by monitoring the passage at the control points, for which the WDT watchdog timer is used, the replenishment of which stops in case of violation of the passage of the command counter at the control points. In the main cycle, the OEWM 63 “feeds” the WDT watchdog timer and increases the cycle counter. The cycle counter is cleared in interrupts when receiving messages and during interrogation of the input module matrix 69 (control points). If the cycle counter is not reset (the functioning algorithm of the unit is violated), then when the cycle counter is increased to a certain value (the count is approximately one minute), the WDT is “refilled”, which leads to a hardware restart of the OEVM 63. This ensures the correct implementation of the algorithm and, in in case of violation after about 1 minute, the OEWM 63 will restart.

When scanning the matrix of input module 69, readings of diagnostic “0” and “1” are made, in case of failure (“1” is read instead of “0” or “0” is read instead of “1”) all TS signals are blocked (set to an undefined state) located in the column and row where the error is detected.

Then, the presence of changes is determined and the blinking mode of the vehicle input signals is monitored. These routines are discussed later.

If there is an input message from RCP-C (i.e., access to the unit), a response is generated depending on the type of request and transmitted to the internal local network.

Change definition cycle. The determination of changes in the input signals of the vehicle is carried out in the interrupt. Interrupts follow every 2.5 ms. Processing of one group - 20 ms. Each input signal of the vehicle is monitored 8 times during the processing period of the group. The input signal of the vehicle is taken as “1” if, out of 8 read states of the input, at least 3 are equal to “1” (for AC signals of 50 Hz). The current state is compared with the previous one and with a difference a flag is set to change the input of the vehicle for processing in the main cycle.

In the routine "Definition of changes" (Fig. 9), which is called from the main loop, the presence of the change flag is checked (there is a change in the state of the TS input). If there are no changes, then the routine exits. If there is a change, the flag “vehicle input change” set in the interrupt is cleared, and then the counter of vehicle input changes (COUNT_TC) increases. The counter is reset in the blink detection routine once every 4 seconds.

If the change is not the first (COUNT_TC counter ≠ 1) or the signal blinking flag is set, exit the subroutine, and provided that COUNT_TC = 1 and with a solid signal from the vehicle, the correctness of the vehicle matrix is checked. With a working matrix of the vehicle, i.e. this vehicle input is not blocked, the flag "transmit change of vehicle input" is set. It is believed that there has been a change in the input of the vehicle and upon request for changes it will be transmitted to the RCP-C. If the input module 69 matrix is faulty, the change will not be transmitted.

Next, the state of the vehicle input is determined by a two-bit code (the state of the vehicle can be: undefined - the input is blocked - 00, state “0” - 01, state “1” - 10, blinking state - 11) and exit from the subroutine.

Cycle definition blinking (see figure 10). The blink detection routine is called once every 4 seconds. The blinking period is 1.5 seconds (40 blinks per minute). With this interval of the change count and the blinking period, at least 5 changes in the state of the input signal of the vehicle will be guaranteed. Therefore, with a steady blinking of the input signal, the COUNT_TC counter in each blink detection cycle will have values ≥ 5. The branches of the algorithm are implemented for the cases: the beginning of the blinking mode of the input signal of the vehicle fell into the 4 second interval, or its completion, or malfunctioning situations, contact bounce, false alarms from interference.
