BRIEF DESCRIPTION OF THE DRAWINGS

In FIG. 1 shows a diagram of a module for loopless diagnostics.

DETAILED DESCRIPTION OF THE INVENTION

According to FIG. 1, the declared module of loop-free diagnostics (100) is connected via the corresponding interface unit (103) to the ALS signals receivers of the first cab and second cab (109, 110) and to the ALS signal receiving coils of the first and second cabs (111, 112).

The interface unit for connecting (103) ALS receivers and coils via a common data bus (105) provides the exchange of diagnostic signals through the DAC / ADC block (104) of module (100).

Module (100) performs diagnostics:

• upon receipt of a command through an activation unit (106), for example, from locomotive control and diagnostic devices connected via an appropriate interface (not shown);

• upon receipt of user commands from the display and input unit (107), using buttons, display, toggle switches, etc., on the basis of which control signals are generated that are transmitted to the microcontroller (101).

During diagnostics, testing of the receiving coils (111) and the signal receiver (109) is carried out if there is a zero cab selection signal from locomotive discrete signals. During diagnostics, testing of the receiving coils (112) and the signal receiver (110) is performed if there is a non-zero signal for selecting a cabin from locomotive discrete signals.

During diagnostics during the diagnostics of coils (111 or 112), the microcontroller (101) generates a control signal, which is transmitted to the interface unit (103), which disconnects the receiving coils (111 or 112) from the receiver (109 or 110) and connects them into one circuit with a block DAC / ADC (104). The microcontroller (101) generates digital data (signals) for the block (101), which converts them into a frequency diagnostic signal, which is fed through the interface unit (103) to the receiving coils (111, 112). The DAC / ADC block (104) digitizes the values of the current and voltage signals in the circuit of the receiving coils (111, 112) and transfers the received digital data to the microcontroller (101), which based on these data performs software filtering of the voltage and current signals at the frequency of the diagnostic signal and determines the parameters of the receiving coils (111, 112) and the state of the receiving coils (111, 112).

During diagnostics during diagnostics of receivers (109, 110), the microcontroller (101) generates a control signal, which is transmitted to the interface unit (103), which disconnects the receiver (109 or 112) from the receiving coils (111 or 112) and connects it to one circuit with a block DAC / ADC (104). The microcontroller (101) generates digital data of the ALS signals for the block (104), which converts their analog signal ALS, which is fed through the interface unit (103) to the corresponding receiver (109 or 110).

When receiving data from the locomotive safety device (113) feedback on the ALS signals received by the receiver 109 (110), the microcontroller (101) of the module (100) automatically determines the state of the receiver 109 (110).

The microcontroller (101) of the module (100) transmits the diagnostic results of the receiving coils 111 (112) and the signal receiver 109 (110) to the display and input unit (107), which can subsequently be transmitted to locomotive control and diagnostic devices (not shown). The transmission of the mentioned information from the module (100) can be performed via a wired (when connected via a wired interface) or a wireless data transmission channel (Bluetooth, Wi-Fi, GSM, GPRS).

Diagnostic data is stored in the memory (102) of the module (100).

The microcontroller (101) expects a command to start diagnostics by means of user interaction with the indication and input unit (107) and / or by receiving a start command from the activation unit (106). After activation, the module (100) analyzes the locomotive discrete signals, in particular, coming from the receiving coils 111 (112) and the receiver 109 (110). Additionally, the module (100) can receive data from speed sensors, with their corresponding connection via a wired or wireless communication principle.

The microcontroller (101) for diagnostics of the receiving coils 111 (112) generates a diagnostic signal using the DAC unit (104) to the circuit of the receiving coils 111 (112) and receives a response signal using the ADC unit (104) from the chain of the receiving coils 111 (112) and performs its filtering, while analyzing the difference between the generated signal and the filtered one. Based on the analysis of the differences between the mentioned signals, the parameters of the receiving coils 111 (112) are determined (inductance, quality factor, impedance, active and reactance). Based on certain parameters, information is received on the state of the receiving coils 111 (112) (serviceable / faulty, open, short circuit, deterioration of parameters).

Microcontroller (101) for diagnostics of the receiver ALS 109 (110) generates a test sequence of ALS signals (ALSN, ALS-EN) using the DAC of the block (104) and receives feedback through the corresponding interfaces of the block (103) about the received signals by the receiver 109 (110) compares the test sequence and the signals received by the receiver 109 (110). According to the results of the comparison of signals from the test sequence and the response from the receivers 109 (110) receive data on the status of the receivers 109 (110) (good / bad).

The diagnostic results of the receiving coils 111 (112) and receivers 109 (110) are displayed on the display unit (106) and stored in memory (102). Also, the diagnostic results can also be transmitted wirelessly to a locomotive diagnostic system device or a remote indication device, such as a mobile phone or tablet.

The indication and input unit (107) may have a different design, for example, the means of indication included in the unit (107) may be light signaling devices (bulbs, LEDs) or a display. The display can be performed in monochrome, color LCD display or touch screen, which also provides input of control parameters. The input means of the block (107) can be buttons, toggle switches, a keyboard (mechanical or touch) or the aforementioned touch screen.

Wireless communication of the module (100) with external devices is realized by introducing into its design an appropriate device that provides this type of communication, for example, a Bluetooth module, Wi-Fi transceiver, NFC module, GSM or GPRS modem.

The interface unit (103) may contain, due to the need for structural design, a set of appropriate connectors to provide wired connections for diagnosed devices or external devices for receiving / transmitting information. Also, it may include wireless communication interfaces, which can be performed regardless of the presence of a wireless module in the design of the module itself (100). The receiving coils 111 (112) and signal receivers ALS 109 (110) can be connected to their respective connectors (group of interfaces) through the unit (103), or connected via a single universal interface of the unit (103).

The module case is shockproof and anti-vandal.

The microcontroller (101) can additionally implement the following functions:

• change the spectrum of the generated diagnostic signal in the chain of receiving coils 111 (112); This function allows you to more deeply evaluate the parameters of the receiving coils: the parameters of the quality factor and inductance at different frequencies at different amplitudes of the test signal;

• change the filtering and processing algorithm of signals received from the chain of receiving coils 111 (112); This function allows you to determine the parameters of the receiving coils in the conditions of inducing signals from rail circuits on the receiving coils;

• change the test sequence of ALS signals (ALSN, ALS ЕН), their amplitude, frequency and phase, as well as add interference spectra for the generated diagnostic signal to the chain of receiving coils 111 (112); This function allows you to perform a deeper diagnosis of the ALS signal receiver: to determine the sensitivity of the receiver and to evaluate the signal reception by the ALS receiver in the presence of interference;

• change the algorithms for working with external devices connected via wired and / or wireless interfaces;

• provide various data exchange protocols.
