Description

Device for electrical centralization of arrows and signals

The device relates to railway transport, and in particular to control equipment and blocking arrows and signals at railway stations.

A device for the electrical centralization of arrows and signals containing control and monitoring objects: arrows, traffic lights, rail circuits, a control panel, an indicator board, a central universal unit for checking and implementing interdependencies, connected to objects of control and monitoring (Efimov V.Yu., Prokofiev A .A ,, Denisov BP, Gorbunov BL Computer centralization of arrows and signals. Automation, telemechanics and communications, 1979, No. 1, pp. 6-9).

The disadvantage of this device is the design complexity due to the need for redundancy of the central unit, because without reserve, failure of this unit leads to a loss of operability by the device.

Closest to the proposed solution in technical essence is a device for electrical centralization of arrows and signals, containing control and monitoring objects, each of which is constantly connected to its corresponding unit for checking and implementing interdependencies, which are also constantly connected between each other in accordance with the geographical plan of the station and connected to the remote control, and with a bulletin board. (Belyazo I.A., Dmitriev V.R., Nikitina E.V. Route-relay centralization. M., transport, 1974, 320 p.). Each unit in this device monitors and controls a specific object, checking the conditions necessary for including this object in the route, closes the object in the route, and then switches off 101150

mapping in accordance with the information coming from the objects of management and control and neighboring blocks.

The disadvantage of this device is the redundancy of the equipment, the relatively low survivability and uneconomical operation. This is due to the fact that at the station, due to the hostility between the routes, only a part of them can be installed at a time. For example, for a station with 100 arrows, the number of such routes will be no more than 8-10 out of the total, its number of routes allowed by the route development of the station, which reaches several hundred or thousands. Only a part of the objects of control and control will participate in these routes, therefore, to check and implement the interdependencies between them, only a part of the corresponding ones will be used; their blocks of the total number of blocks (no more than 15-20%). The remaining blocks of verification and implementation of interdependencies will be idle, spending unproductive energy.

The objective of the utility model is to simplify the device and save energy.

The problem is solved in that the device for electrical centralization of arrows and signals, containing an information input unit, an indication unit, executive units, control and monitoring objects, is equipped with information processing, memory, coordination, executive unit selection, executive unit connections, and outputs and inputs blocks of information processing, memory, information outputs and inputs of executive blocks, block for selecting executive blocks, block for connecting executive blocks, inputs of an indication block, you ode information input unit are connected to respective inputs and outputs block matching blocks selecting execution units are interconnected by horizontal and vertical trunks, forming a first rectangular matrix, which blocks the lower row are connected with similar facility management and control of the last column of the blocks

Actuator selection blocks 8.1.1, ..., 8.NM and actuator connection blocks 9.1.1, ..., 9.K.M are interconnected horizontal and vertical tires - trunk and forming two rectangular matrices HI and H2. Blocks 8.1.M, ..., 8.N.M of the bottom row M of the matrix HI are connected to the objects of the same control and control 4.1, ..., 4.N. Blocks 8.N.1, ..., 8.N.M

of the right column N of the same matrix are connected to the nerve trunk inputs and outputs 13.1, ... ДЗ.М of the executive blocks 3.1, ..., З.М. Blocks 9.1.1, ..., 9.1.M of the first column of matrix H2 are connected to the second main inputs and outputs 14.1, ..., 14.M of blocks 3.1, ..., Z.M.

The selection blocks of the executive blocks 8.IJ, where I is the column, J is the row of the matrix H 1 (, ..., K;, ..., M) contain relays whose windings are the information inputs 10.LJ of these blocks and are connected (see Fig. 1) with the corresponding outputs of the matching block 7. The switching contacts SIJPL of the relay of the 8.IJ block (where L is the number of types of actuating blocks, P is the number of conductors connecting the block of this type with the corresponding control and monitoring object) are connected with the same opening (rear) contacts 8.I.J + 1.PL of the relay of the block 8.I.J + 1, forming the line I - that object of management and control. The closing (front) contacts 8.I.J.PL of the block 8.I.J are connected to the same contact contacts of the same name 8.1 + 1.J.PL of the block 8.1 + 1.J, forming the first trunk of J - that executive block, corresponding to I - that control and monitoring object.

In the device K "M" N. As an input unit 1 and an indication unit 2 in the device, for example, standard remote control and a panel of block route-relay centralization (BMRC) can be used as executive units 3.1, ..., З. M - relay blocks BMRC; as an information processing unit 5, a microprocessor controller K 580 IK80; memory unit 6 (Arkatov BC, Didenko KN, Ivanchenko VN, Rosen Yu.V. Microprocessor technology in railway automation systems. - Automation, Telemechanics and Communication, J42l, 1982, p. 4-8), as a coordination unit 7 - input and output elements of discrete signals included in the microprocessor set KTS JMYC - 2 (Arkatov BC, Didenko KN, Ivanchenko VN, Rosen Yu.V. Microprocessor technology in railway automation systems. - Automation , telemechanics and communications, 2l, 1982, p. 4-8); as blocks for selecting actuating units 8 and connecting blocks for actuating units 9, relays of the NMSh type can be used (Equipment for railway automation and telemechanics. Soroko V.I., Razumovsky B.A. M., Transport, 1976. 704 pp.).

The device operates as follows. In the initial state, all the relays of blocks 8 and 9 are turned off, not one of the blocks 3.1, ..., З.М is connected to any of the control and monitoring objects 4, and is not connected to any other executive block 3.

After pressing the start and end buttons of the route, the information processing unit 5 determines the place of the beginning and end of the route (traffic light, track section), gender (train or shunting), direction (even, odd). For this purpose, each route button should be assigned a specific code number, for example, three-digit: the train buttons of even direction - even, odd - odd. If the high order bit is encoded with zero, this means, for example, that the button belongs to the train route. All shunting and route buttons are also assigned three-digit decimal numbers, but the senior digit is encoded, for example, one, 5

nice. All variant route buttons in the high order are assigned a deuce, and the cancel and dial buttons are encoded with a triple and a four, respectively. In this case, the numbers of the initial and final buttons form the encoded number of the route, and also carry information about its kind, direction, beginning and end of the route. For example, route number 024019 means an even train route limited by train buttons 24 and 19.

In the memory block 6, information is recorded about which control and monitoring objects are included in each route allowed by the station's track development. The information processing unit 5, by the route number, finds an array of information corresponding to this route, determines for each I of that control and control object (I 1, ..., C, where C is the number of objects included; they are in this route) corresponding a free execution unit 3.J (J 1, ..., M) is supplied to it and, via the matching unit 7 and .1.J, includes an execution unit selection block corresponding to this object located on the Jth row of the matrix HI. At the same time, the I - th control and monitoring object through the J - th trunk of the HI matrix will be connected to the J - th executive unit. At the same time, in memory block 6, it is noted that the 8.I.J and 3.J blocks are occupied in this route. After connecting the last object C to the corresponding one; the executive unit, the information processing unit 5 finds a free trunk F of routes (F 1, ..., K) and, through the matching unit 7 and inputs 11.1.J, turns on the relay of blocks 9.1.J of the matrix H2 located at the intersection of the highway route F and horizontal highways of the same matrix corresponding to the executive units involved in this route. At the same time, information about busy line F and busy connections of executive units of matrix H2 is taken into memory block 6.

poverty of track sections, etc.), through the information inputs 12.1 (I 1, ..., C) of the corresponding executive units, compares them with the states that they should have in this route (this data is recorded in memory block 6) and generates the necessary control commands (to switch arrows, turn on the initial relays, etc.).

Thus, the information processing unit 5 performs route dialing functions that are not related to security conditions. The remaining functions of closing and opening routes are performed by executive units 3.

Similarly draining, the installation is as follows; its route. At the same time, busy blocks are not used on this route. After the closure of 4.1 - that control and monitoring object (I 1, ..., С), the matching unit 7, constantly monitoring; changing the state of these objects, includes the corresponding; the executive unit selection block 8.IJ of the matrix HI and the block for this object connecting executive blocks 9.FJ, thereby freeing block 3.J from participating in route F. The mark on the occupancy of these blocks in memory block 6 is erased. After that, block 3.J can be involved in another route. Consequently, the same execution unit can be used in time-sharing mode on any route allowed by the station's track development.

Due to the absence of a rigid connection between the control units of the executive units, the failure of some of the latter will not affect the operability of the device, because this block can be automatically removed by operation of block 5 and replaced with any free block of this type.
