Description

The invention relates to the field of automation and communication and can be used in railway transport to alert those working in the area of operation of the track machine and fencing of the work site.

A known system for fencing a place of work and alerting workers on railway tracks, containing installed on the foot of a rail of a railway track at a given distance on both sides of the boundaries of the work site, rolling stock detection sensors (DOP), each of which is equipped with a radio station (RSDOP), portable fencing devices , made in the form of radio-controlled signaling devices (RPSO), located at a given distance on both sides of the boundaries of the work site, a KOP-M annunciator installed on the track machine and a collective portable annunciator (KPS) located at the work site, made with the ability to interact via a radio channel with RSDOP of each DOP, RPSO and KOP-M, while the KPS is also designed to interact with the on-board radio communication device of the locomotive approaching the work site of the rolling stock for negotiations between the work manager and the driver via the train radio channel (RU2655566C1, B61L 23/06, 28.05. 2018).

The known system, chosen as a prototype, increases traffic safety and safety of those working on railway tracks as a result of reducing the influence of the human factor on their provision.

The disadvantage of the known warning system working in the area of operation of the track machine and the fencing of the work site using the KOP-M device installed on the track machine is the need to install sensors for detecting rolling stock at a distance of 2.0 - 2.5 km and radio-controlled portable fencing devices at a distance 1.0 - 1.7 km from the boundaries of the place of work, which diverts significant human resources, given the absence of signalmen.

The technical result of the proposed invention is to simplify the warning system about the approach of rolling stock, fencing of the place of work and technological communication of the track machine through the use of a centralized auto-blocking system, which makes it possible to abandon the sensors for detecting rolling stock and portable fencing devices and makes it possible to use the system without using signalists.

The technical result is achieved by the fact that the warning system about the approach of rolling stock, fencing of the place of work and technological radio communication of the track machine contains a remote control and a radio station of the work manager, an interface unit, a control and switching unit installed on the track machine, with outputs connected to a siren, an optical emitter and low frequency amplifier loaded on loudspeakers, input - to the output of the microphone for monitoring reproduced control and warning signals, and inputs / outputs - to the outputs / inputs of the intercom of the track machine mechanic and the radio station for communication with the radio station of the work manager, while the interface unit includes the controller , the input of which is connected to the receiver of navigation signals, the first input / output - to another input / output of the control and switching unit, the second input / output - to the output / input of the radio communication station with the remote control of the work manager, and the third input / output of the controller is connected EN with the output / input of the communication radio station with a repeater connected through the inter-office communication line access point nearest to the work site for interaction through the interface device with the hardware and software complex of the centralized auto-blocking system, the corresponding inputs / outputs of which are connected to the outputs / inputs of the hardware and software device automated workplace of the station attendant.

In this case, the control and switching unit is configured to register in real time the activation of warning signals that prohibit and allow the movement of fence signals.

In the proposed technical solution, the fencing of the work site, which consists in warning the locomotive driver about the need to stop the train due to the presence of an obstacle at the work site, is provided by sending the corresponding signal from the work manager's console to the hardware and software complex of the centralized automatic blocking system, which provides automatic transmission via automatic locomotive signaling of a train stop signal, informing the station attendant about it.

As a result, a simplification and increased reliability of the warning system and fencing of the work site is provided, which makes it possible to abandon the use of signalmen.

The essence of the invention is illustrated by a drawing, which shows a structural diagram of the proposed warning system about the approach of rolling stock, fencing of the place of work and technological radio communication of the track machine.

The warning system about the approach of rolling stock, fencing of the place of work and technological radio communication of the track machine contains a remote control 1 and a radio station 2 of the work manager installed on the track machine 3, an interface unit 4, a control and switching unit 5 (BUK 5), outputs connected to a siren 6 , an optical emitter 7 and an amplifier 8 of low frequency (ULF 8), loaded on loudspeakers 9, the input is to the output of the microphone 10 for monitoring the reproduced control and warning signals, and the inputs / outputs are to the outputs / inputs of the intercom 11 of the mechanic of the track machine and radio station 12 communication with radio station 2 of the work manager.

In this case, the interface unit 4 includes a controller 13, the input of which is connected to the receiver 14 of navigation signals, the first input / output to another input / output of the BUK 5, the second input / output to the output / input of the radio station 15 for communication with the remote control 1 of the work manager , and the third input / output of the controller 13 is connected to the output / input of the radio station 16 with a repeater 17 (RT 17) connected through the point 18 of access of the inter-office communication line 19 closest to the work site for interaction through the interface device 20 (US 20) with the hardware -program complex centralized system 21 automatic blocking, the inputs / outputs of which are connected to the outputs / inputs of the hardware and software device of the automated workstation 22 of the station duty officer (AWP 22 DSP).

BUK 5 is configured to register in real time the activation of warning signals and prohibiting and allowing movement of fence signals.

All devices installed on the track machine 4 are powered from the on-board network of the track machine through a power unit (not shown in the drawing).

The warning system about the approach of rolling stock, fencing of the place of work and technological radio communication of the track machine functions as follows.

Information about the track circuits occupied by the track machine of the rolling stock approaching the place of work is received every 0.5 s from the hardware and software complex of the centralized automatic blocking system 21 through the interface device 20 into the inter-office communication line 19 and through the entry / exit access point 18 closest to the place of work repeater 17 and over the radio channel to the radio station 16, which transmits it to the controller 13 of the interface unit 4.

At the input of the controller 13 in real time from the output of the receiver 14 of navigation signals interacting with the navigation system 23 GLONASS / GPS, the coordinates of the location of the track machine 3 are received.

Based on the results of comparing the data on the track circuits occupied by the approaching rolling stock and the coordinates of the location of the track machine 3, received from the output of the receiver 14 of the navigation signals, the controller 13 generates the corresponding commands and transmits them to the BUK 5. Buk 5, based on the received commands, initiates the transmission to the input of the ULF 8 corresponding signals reproduced by loudspeakers 9 - control tones, indicating the absence of an approaching rolling stock and serviceability of the warning system, or warning tones indicating the approach of rolling stock. Simultaneously with the audible control or warning signals, BUK 5 initiates the activation of the optical emitter 7 and, when the warning signal is played, the siren 6.

In addition, the controller 13, according to the data from the centralized auto-blocking system 21, generates a message about the direction of movement of the rolling stock and transmits it to the BUK 5, which, before the command to turn on the warning signal, transmits it to the ULF 8 for reproduction by the loudspeakers 9 of the voice message about the direction of movement of the approaching rolling stock ...

In this case, the control or warning signals reproduced by the microphone 10 are fed through the BUK 5 to the controller 13 of the interface unit 4, which correlates them with the command sent to the BUK 5.

When the reproduced signal corresponds to the transmitted command, the controller 13 generates a message confirming the normal functioning of the system and transmits it through the radio station 16 via a radio channel to the repeater 17, which sends it through the access point 18, the inter-office communication line 19 and the interface device 20 to the hardware and software complex of the centralized system 21 automatic blocking, which transmits it to the hardware and software device AWP 22 DSP. The corresponding alarm is reproduced on the AWP 22 chipboard monitor.

In the event of a discrepancy between the reproduced signal and the transmitted command, the controller 13 generates an alarm message transmitted through the radio station 16 over the radio channel to the repeater 17, which transmits the alarm message through the access point 18 through the inter-office communication line 19 to the interface 20. The interface device 20 converts the correspondingly received alarm message and transmits it through the hardware and software complex of the centralized automatic blocking system 21 to the hardware and software device AWP 22 of the EAF, on the monitor of which the alarm is reproduced with the identification of the failed warning device on the track machine 3. The controller 13 in this case transmits a failure message to the BUK 5, which generates an emergency signal and through the ULF 8 transmits it to the input of the loudspeakers 9 for playback.

If there are no obstacles at the work site for movement along the adjacent track, a message is periodically received from the control panel 1 of the work manager via the radio channel to the radio station 15 of the interface unit 4, indicating the possibility of the rolling stock passing along the adjacent track without stopping, which the radio station 15 transmits to the controller 13. Received message the controller 13 through the radio station 16 over the radio channel transmits to the repeater 17, which, through the access point 18 via the inter-office communication line 19, directs it to the interface 20. The interface device 20 transmits a message about the absence at the work site of obstacles for movement along the adjacent path through the hardware and software complex of the centralized automatic blocking system 21 to the hardware and software device AWP 22 DSP, on the monitor of which the corresponding alarm is reproduced.

The acknowledgment signal of the presence in the AWP 22 of the DSP that allows the movement of signaling is transmitted by the hardware and software device AWP 22 by the DSP through the hardware and software complex of the centralized auto-blocking system 21, the interface device 20, the inter-office communication line 19, the access point 18 to the repeater 17, and then via the radio channel to radio station 16 and through the controller 13 to the radio station 15 for transmission over the radio channel to the console 1 of the work manager. In this case, an optical signal is reproduced on the console 1, corresponding to the signal turned on on the AWP 22 of the EAF.

If an obstacle arises at the work site for movement along the next path, the work manager sets on the control panel 1 an appropriate message, which transmits via the radio channel to the radio station 15, from the output of which to the controller 13 and through the radio station 16 connected to the controller 13 via the radio channel to the repeater 17, which through access point 18 on inter-office link 19 directs it to interface 20. The interface devices 20 converts the received message about the occurrence of obstacles at the work site for movement along the adjacent path and transmits it to the hardware and software complex of the centralized automatic blocking system 21 for transmission to the hardware and software device AWP 22 DSP, on the monitor of which the corresponding optical and sound signaling is played.

In this case, the hardware and software complex of the centralized automatic blocking system 21 transmits, via the automatic locomotive signaling system (ALS), a command to the train locomotive to stop the train at the border of the work site, thereby fencing the work site.

Confirmation of sending a train stop signal is transmitted by the hardware and software complex of the centralized auto-blocking system 21 through the interface 20 through the inter-office communication line 19 through the access point 18 to the input of the repeater 17, which transmits it via the radio channel to the radio station 16 and through the controller 13 to the input of the radio station 15, which sends him by radio to the control panel 1 of the work manager. At the same time, the stop signal transmitted to the locomotive of the approaching rolling stock, signaling about the fence of the work site, is reproduced on the control panel 1 of the work manager.

If there is no confirmation on the panel 1 of the work supervisor, an alarm is triggered.

When the obstacle to movement at the work site is eliminated, the work manager transmits from the control panel 1 the corresponding message arriving at the radio station 15, from the output of which to the controller 13, to the input of the radio station 16 and via the radio channel to the repeater 17, which sends it through the access point 18 along the line 19 inter-office communication to interface 20.

The interface device 20 transmits the received message to the hardware and software complex of the centralized auto-blocking system 21, which transmits via the automatic locomotive signaling system (ALS) to the train locomotive a traffic permit signal or a signal to open an exit traffic light. The message about the permission of movement is transmitted by the hardware and software complex of the centralized automatic blocking system 21 to the hardware and software device on the AWP 22 of the EAF, on the monitor of which the corresponding alarm is reproduced.

The hardware and software complex of the centralized auto-blocking system 21 transmits confirmation of the sending of the traffic permission signal through the interface 20 via the inter-office communication line 19 and through the access device 18 to the repeater 17, which transmits the confirmation via the radio channel to the radio station 16 and through the controller 13 to the input of the radio station 15, which sends it over the radio channel to the control panel 1 of the work manager, on which the traffic permission signal transmitted to the locomotive is reproduced.

If there is no confirmation on keypad 1, an alarm is played.

The organization of service radio communication is carried out using a portable radio station 2, attached to the head of work, connected by a radio channel with a radio station 12, through which messages (commands) of the head are sent to the BUK 5, and from its output to the ULF 8 for playback by loudspeakers 9.

With the help of an intercom 11 (PVU 11) connected to the BUK 5, the mechanic of the track machine can negotiate with the work manager through the radio station 12, which interacts by radio with the work manager's radio station 2.

In the BUK 5 block there is a recorder, which fixes, with reference to Moscow time, the activation of warning signals and prohibiting and permitting signals of the fence (not shown in the drawing).

Interaction with the on-board radio communication device of the locomotive approaching the work site can be provided using the train radio communication devices of the track machine.

Thus, the use of a centralized auto-blocking system and warning devices, fencing and radio communication installed on the track machine, interacting with it, ensures the simplification of the system and increases the reliability of notification of those working in the area of operation of the track machine about the approach of rolling stock along the next track, timely warns the train driver about the need stopping in the presence of an obstacle to traffic at the work site and provides operational management of the work, which makes it possible to increase the safety of people and traffic safety without the use of additional human resources.
