When switching power from the main feeder to the backup or back, the intermediate relay includes a stopwatch, which determines the time of switching the feeders. The time relay is used to check the overlap of traffic lights for a given time.

The known invention provides the ability to control the time of power outages at the posts of electric centralization, but does not establish the reasons for unauthorized blocking of the traffic signal, which do not allow the use of the traffic light when setting the corresponding route.

It is known (RU 2360819 C1, 07/10/2009) a device for automatic crossing signaling, including axle counting points installed at the boundaries of controlled sections of the crossing, containing track sensors and floor signal converters, counting devices connected by data exchange circuits, uninterruptible power supply devices , linear circuits, actuating devices of moving automation, relay of artificial restoration of the initial state of an automatic moving alarm device, including a relay an alarm relay for monitoring the health of a set of flashing devices connected to the second input of the executive devices of moving automation connected to the input of the information transmission equipment to the station, the output of which is connected to a linear circuit, the input of the relay for restoring the initial state of the automatic moving alarm device is an input from an external power source.

The known device is designed to determine the status of the controlled sections of the move, carries out logical control of the progress of the move; It ensures consistent and safe operation of the device as a whole due to the continuous diagnosis of system equipment, but does not control the unauthorized actions of the automatic crossing signaling.

The closest analogue is a system for monitoring the operation of traffic lights in railway transport, including relay and floor equipment, typesetting and executive circuits for setting train routes (see the book "Devices of railway automation, telemechanics and communications", Moscow, 2006, part I , p. 383-385).

The known device monitors and controls alarm and centralization devices from a central control center, but does not provide control over the operation of traffic lights of devices in case of their unauthorized overlapping of actions.

The objective of the invention is the creation of a system for monitoring the operation of traffic lights in railway transport, ensuring the safety of train movement on a given route in the event of unauthorized overlapping of traffic lights with permission for prohibitory indication.

The technical result of the invention is to increase the reliability of traffic control, ensuring the safe movement of trains along a given route.

This is achieved by the fact that in the control system of the traffic lights in the railway transport, which contains the automated workplace of the train dispatcher or station duty officer (AWP DNTs or AWP DNP), an actuator including a serially connected route route input unit and a route route execution unit, corresponding outputs which are connected to the display panel AWP DNTs or AWP DNP, as well as a control unit, and the outputs of the block execution route are connected to the control equipment of traffic lights, and control The output of the hardware-software device AWP DNTs or AWP DNP is connected to the input of the route input unit, according to the invention, the control unit is made in the form of a logical control unit, including series-connected traffic light interrogator, decoder, control unit, time selector and inverter, as well as the unit determining the status of the traffic light, the first, second and third control inputs of which are connected to the outputs of the decoder, time selector and inverter, respectively, one of their outputs is to the inputs of the of the route, and other outputs are connected to the corresponding inputs of the display panel AWP DNTs or AWP DNP, while the inputs of the polling unit of traffic lights using communication channels are connected to the control equipment of traffic lights, and the hardware-software device AWP DNTs or AWP DNP is connected via a communication channel to the hardware - a software device for the automated workplace of the dispatcher of the communication and signaling service (AWP ШЧ).

The essence of the claimed system is illustrated in the drawing, which shows a structural diagram of one of the options for implementing the proposed system for monitoring the operation of traffic lights in railway transport.

The system for monitoring the work of traffic lights in railway transport contains an automated workstation 1 for a train dispatcher (AWS DNTs), an actuator 2, which includes a serially connected block 3 for entering the route and block 4 for monitoring the execution of the route, the corresponding outputs of which are connected to the inputs of the board 5 of the arm of the DNTs, other inputs connected to the corresponding outputs of the hardware-software device 6 AWP 1 DNTs, the control output of which is connected to the input of the block 3 input route I am. The corresponding outputs of the block 4 execution route are connected to the control equipment of traffic lights 7.

The system also contains a logical control unit 8, including a series-connected traffic light interrogation unit 9, a decoder 10, a control unit 11, a time selector 12 and an inverter 13, as well as a traffic light status determination unit 14, the first, second and third control inputs of which are connected to the outputs, respectively a decoder 10, a time selector 12 and an inverter 13, one of the outputs is to the inputs of the route execution unit 4, and others to the corresponding inputs of the display panel 5 AWP 1 of the DC.

The inputs of the block 9 of the survey using communication channels are connected to the control equipment of traffic lights 7.

The corresponding outputs of the hardware-software device 6 AMP 1 DCC or chipboard through a communication channel are connected to the corresponding inputs of the hardware-software device 15 of the automated workstation 16 of the communication and signaling service manager (AMP 16 RF). The hardware-software device 6 is also provided with an information input unit 17.

Blocks 3, 4 and 9 are provided with a corresponding power supply unit 18.

The system is used as follows.

At the control section of the train dispatcher, there are 7 different types of traffic lights - input, output, route. The polling unit 9 cyclically polls the state of operation of the traffic lights 7 and transmits information about their state in the form of corresponding codes to the input of the decoder 10 of the logical control unit 8. Block 14 determines the state of traffic lights 7 depending on the signals at its control inputs.

Block 4 selects the traffic lights involved in the formation of the train following the route, in accordance with the information from the route input unit 3, prepared by the train dispatcher from the workstation 1 using the information input unit 17 and the hardware-software device 6 AWP 1 of the center. When preparing the route block 3 uses the power source 18.

During normal operation of the traffic light 7, the decoder 10 generates the corresponding code signal, which is fed to the first control input of the block 14, as well as to the input of the block 11. The control block 11 confirms this state of the traffic light 7 by the absence of a signal at its output, while the time selector 12 also no signal. In this case, the unit 14 for determining the status of the traffic light at the output generates a signal characterizing the normal state of the monitored traffic light 7.

In case of failure of the traffic light 7, for example, lamp burnout, failure or malfunction of the traffic light relay, etc., the decoder 10 through the polling unit 9 receives a modified signal code of the traffic light 7, which is fixed by the control unit 11 and transmitted to the time selector 12. In this case, the block 14 is in a standby state.

The time selector 12 estimates the duration of a traffic light failure.

If the duration of the traffic light failure does not exceed a predetermined fixed value, for example, the route formation time, then the signal from the output of the selector 12 is sent to the second control input of block 14. In this case, in block 14, for this traffic light, the highest priority of the signal is enabled, allowing block 3 input the route to prepare the route, but not to execute it in block 4 of the route until the traffic light 7 is in good condition.

If the duration of the malfunction exceeds a fixed value, then through the inverter 13 the signal is fed to the third control input of block 14. In this case, the second control input of block 14 is blocked and a signal is generated about the permanent malfunction of the controlled traffic light 7. In this case, block 4 forms a ban on further route formation faulty traffic light 7. Information about its faulty state enters the block 3 control the execution of the route and blocks on the scoreboard 5 those sections of the circuit that include the faulty traffic light 7.

Information about the route being formed, the status of traffic lights 7, both participating and not participating in the route controlled by the train dispatcher, from the corresponding outputs of blocks 3, 4 and 14 and device 6 is displayed on the display 5 of the AWP 1 of the DC, which allows you to clearly and efficiently control the logic the formation of the route and timely take measures to eliminate the malfunction of traffic lights.

At the same time, the train dispatcher also informs the duty officer directly or through a hardware-software device 15 about the status of traffic lights 7, which allows timely troubleshooting of traffic lights and with the least loss of time to organize a given route of the train.
