Description

The utility model relates to traffic safety at the intersection of highways with railways at the same level and can be used at level crossings equipped with an automated remote control on duty and automatic crossing signaling.

The protection system for regulated railway crossings contains automatic crossing signaling devices that inform vehicle drivers of the approach to moving the train and / or are serviced by duty officers. A level crossing equipped with a cross signaling is fenced by leveling traffic lights, and a level crossing with a duty officer is additionally equipped with automatic, electric, mechanized or manual (horizontally rotary) barriers and barriers. At the crossing traffic lights, two red lights are horizontally located, which alternately light when the passage is closed. Simultaneously with the inclusion of crossing traffic lights, acoustic signals are switched on. In accordance with modern requirements, at individual crossings without a duty, the red lights of the crossing traffic lights are supplemented by white-moonlight. White-moon fire during an open passage burns in a blinking mode, indicating the serviceability of the devices; when closed - not lit. If the white-moonlight goes out and the red lights are off, the drivers of vehicles must personally verify that there are no trains approaching. At level crossings, traffic lights are switched on by pressing a button on the leveling guard. After that, at the barrage (shunting) traffic light, the red light goes out and the moon-white turns on, allowing the movement of the railway rolling unit. Additionally, electric, mechanized or manual barriers are used. At level crossings, traffic lights are switched on by pressing a button on the leveling guard. After that, at the stoplight, the red light goes out and the moon-white turns on, allowing the movement of the railway rolling unit. Additionally, electric, mechanized or manual barriers are used.

Currently, the urgent problem is the organization of places of safe intersection of roads and railways by monitoring the operability and control of all railway crossing protection devices: leveling lights, acoustic alarms, barriers of all types, barriers, control panels and traffic lights.

A control device for automatic crossing signaling is known, comprising two counting devices connected by data exchange circuits, two uninterruptible power supplies, linear circuits, artificial restoration relays of an automatic crossing alarm device, a health monitoring relay of a set of blinking devices, a driver of control signals for actuating devices of moving automation, specifically for switching power circuits of lamps of traveling traffic lights and aku static devices (calls). Counting and solving devices are designed to determine the status of controlled areas of moving (free, busy); to turn on and off the switching relay; to control the logic of the move; to ensure consistent and safe operation of the device as a whole due to the continuous diagnosis of system equipment; for transmitting voltage supply points counting axes.

The disadvantages of the known device is the low level of traffic safety caused by the following circumstances:

- the signal that controls the on / off crossing signaling is generated on the basis of data from the proximity sensors of the rolling stock installed in the axle counting points at the borders of the monitored track section having a fixed length, therefore, in the vast majority of cases, the crossing closes prematurely. At the same time, due to the significant delay and the lack of indication of the countdown time of the closed crossing, motorists have doubts about the health of the crossing signaling, and they can start moving when the crossing is closed, which leads to a low level of traffic safety;

- the lack of formation of control signals for obstructive traffic lights to transmit to the driver information about an emergency at the crossing;

- lack of control of the crossing area, in particular, in case of an emergency at the crossing (a stopped car, a landed cargo, etc.).

A control device for a railway crossing protection system, RU 2565159 C2, publ. 10/20/2015. The protection system includes traffic lights A and B, acoustic signaling in the form of a voice informant and two horn loudspeakers, barriers, four electromechanical barriers. The control device contains an uninterruptible power supply, a duty operator post at the nearest railway station, an automated moving attendant console with a control panel, configured to locally generate control signals for moving protection devices in an emergency, a programmable logical moving control controller, data collection and processing devices with proximity sensors of rolling stock installed in points of axle counting at the boundaries of the monitored track section on each of n railway tracks, a device for monitoring the crossing zone in the form of a device for collecting and processing data from loop inductive sensors installed in the crossing zone on each of n railway tracks, a driver for crossing traffic lights, acoustic signaling, barriers, electromechanical barriers; the inputs of the programmable logic controller are connected to the outputs of the devices for collecting and processing data from proximity sensors, with the output of the moving zone control device, with a control panel on the automated console of the person on duty to move, while the first output of the programmable logic controller is connected to the input of the shaper of signals for controlling the devices for moving protection. The control device also comprises a duty operator post at the nearest railway station, including a video monitor, a diagnostic information display device, a transmitting unit of the wireless subsystem, a duty operator console; a video monitor by means of a video signal transmission unit displays information from two video cameras placed on different sides of the level crossing; on the device for displaying diagnostic information in real time, the current state of the devices on the move is displayed; the output of the transmitting unit of the wireless subsystem is the information wireless output of the railway crossing protection system for communication with the receiving unit of the wireless communication subsystem located in the locomotive driver’s cab. The post of the operator on duty at the nearest railway station is made with the possibility of remote control of all available devices of the crossing protection system.

The on-duty operator for moving has the ability to switch the devices of the railway crossing protection system into local control mode. At the same time, control from the desk of the duty operator at the nearest railway station is blocked. In the local control mode, the operator on duty has the ability to force the boom devices to lower position or hold them in the lower position by pressing and holding the corresponding buttons on the control panel.

This technical solution was made as a prototype of this utility model.

The disadvantage of the prototype is the fact that the signal that controls the on / off crossing signal is generated on the basis of data from the proximity sensors of the rolling stock installed in the axes counting points at the boundaries of the monitored track section having a fixed length, therefore, in the vast majority of cases, the passage closes prematurely. This causes intermittent vehicles at the crossing. In addition, due to a significant delay and the lack of indication of the countdown time of a closed level crossing, truck drivers have doubts about the health of the leveling alarm system and they can start moving when the level crossing is closed, which leads to a low level of traffic safety.

The low level of traffic safety is also caused by the lack of formation of control signals for obstructive traffic lights to transmit information to the driver about emergency situations at the crossing.

The objective of the utility model is to increase the safety level of railway and road transport at level crossings by reducing the closing time and providing an indication of the countdown time of the closed level crossing, as well as by generating control signals for traffic lights to transmit information about the emergency situation at the level crossing.

The problem is solved due to the fact that in the control device of the railway crossing protection system, containing an uninterruptible power supply, an automated remote control desk officer with a control panel, configured to locally generate control signals for crossing protection devices in an emergency, a programmable logic controller, collection devices and processing data from proximity sensors of rolling stock installed in points of axle counting at the borders of the controlled railway tracks, a crossing zone control device, a driver for crossing traffic lights, acoustic signaling, barriers, electromechanical barriers, and the inputs of a programmable logic controller are connected to the outputs of data acquisition and processing devices from proximity sensors, with the output of a crossing zone control device, with a shield control on the automated remote control of the person on duty, while the first output of the programmable logic controller is connected to according to the utility model, the control device is equipped with a device for generating a countdown time for a closed crossing and a diagnostic device, the inputs of which are connected to the corresponding outputs of a programmable logic controller, while the control device is equipped with devices for collecting and processing data from control sensors the passage of the train through the railway crossing, the outputs of which are connected to the inputs of the signal driver I protect the moving device, the driver is configured to control traffic lights obstruction.

Thanks to the implementation of the distinguishing features of the utility model, a technical result is achieved consisting in increasing the level of traffic safety.

The device for forming the countdown time of a closed crossing provides a visual indication and confirms the serviceability of the crossing signaling, so that drivers have no doubts about the serviceability of the crossing signaling, and they do not go to a dangerous section.

The generation of control signals for turning on / off the crossing protection devices not only on the basis of data from the proximity sensors of the rolling stock installed in the axle counting points at the borders of the monitored track section, but also on the basis of data from the sensors controlling the passage of the train through the railway crossing, provides the optimal time for closing the crossing , which eliminates the possibility of drivers having doubts about the serviceability of the crossing signaling, and they do not go to the crossing.

The formation of control signals by obstruction traffic lights allows timely transfer to the driver of information about the emergency situation at the crossing and to eliminate a collision.

The presence of a diagnostic device allows, during operation, to identify failures and malfunctions of individual blocks of the control device to transfer them to the automated remote control on-duty, which also increases the level of security.

Programmable logic controller 5 is made in Wi e 2 of a computing device 27, 28 for the left and right directions of approaching trains.

The output of the uninterruptible power supply 2 is connected to the inputs of the computing devices 27, 28. The outputs of the devices 6-9 for collecting and processing data from the proximity sensors 10-13 are connected to the inputs of the computing devices 27, 28. The output of the device 14 for collecting and processing data the sensor 16 for controlling the passage of the train through the railway crossing from the left direction is connected to the input of the computer 27, and the output of the device 15 for collecting and processing data from the sensor 17 for monitoring the passage of the train through the railway crossing from the right direction is connected to the input ohm computing device 28. At the input of the device 18 monitoring the crossing zone receives information from sensors 29 located at the intersection of the highway and railways. The outputs of the device 18 for monitoring the zone of movement are connected to the inputs of the counting devices 27, 28. The input of the device 19 for generating the countdown time of the closed moving is connected to the output of the counting and deciding device 27, the output of the device 19 is connected to the device 30 for the indication of the countdown time of the closed moving made , in particular, in the form of a board. The inputs of the diagnostic device 20 are connected to the outputs of the computing devices 27, 28. The output of the diagnostic device 20 is connected to the automated remote control 3 of the transfer officer. The outputs of the automated console 3 on duty and the control panel 4 are connected to the inputs of the calculating device 27. The calculating devices 27, 28 of the programmable logic controller 1 are connected by two-way communication with the shaper 21 of the control signals of the protection devices for moving, which in turn is connected with the automation of the devices protection of moving, namely: crossing traffic lights 22, acoustic signaling 23, barriers 24, electromechanical barrage devices 25, obstruction traffic lights 26.

The control device of the railway crossing protection system operates as follows.

The calculating and solving devices 27, 28 through the driver 21 of the control signals for the crossing protection devices control the traffic lights 22, the stop lights 26, the acoustic signaling 23 (detectors), the position of the barriers 24 and the electromechanical devices 25 of the barrier.

When the train is approaching from any direction, the calculating devices 27, 28 send to the driver 21 of the protective devices control signals a command to turn on the inhibit signal — a red lamp at the crossing traffic lights 22, turn off the permitting moon-white lights at the crossing traffic lights 22, and also a command to the inclusion of an acoustic alarm 23. The device 18 for monitoring the crossing zone, receiving information from sensors 29 located at the intersection of the road and railroads, generates commands for closing 24 The term barriers (barriers bars are translated in the horizontal position) and the switch device 25 barrage (transfer them to the upper position, preventing movement of the vehicle). Moving is considered closed.

The device 19 for generating the countdown time of the closed crossing by the signal from the computing device 27 calculates the actual time of arrival of the train to the first section of approach, as well as the time of passage of the train (time of closed crossing). On the display device 30, the countdown time of the closed passage is displayed.

A prerequisite is the introduction of logical dependencies between the crossing traffic lights 22 and the obstruction traffic lights 26 with red and moon-white lights that act as barriers for railway rolling stock. The computing devices 27, 28 give the shaper 21 a command to turn off the inhibit signal — the red lamp at the obstruction lights 26 and enable the moon-white lights at the obstruction traffic lights 26,

Through the automated remote control 3 using integrated video surveillance, the on-duty duty officer controls the closure of the crossing, the operation of all barrage and signaling devices, and the passage of rolling stock without consequences.

In the event of an emergency (finding vehicles on the railroad tracks) when the crossing is closed, the duty officer immediately presses the button on the shield 4 to switch the traffic lights 22 and to turn on the inhibit signal at the obstruction traffic lights 26 for an emergency stop of the rolling stock. The control signal is transmitted to the calculating devices 27, 28, then to the driver 21, the red signal is turned on at the obstruction lights 26, and the locomotive driver is given an acoustic signal to stop the train by means of an acoustic signal 23 (from a voice detector). In addition, the person on duty on the pedestal has the ability to manually translate any of the electromechanical device 25 of the fence into the lower position using a special hook handle.

After the train enters the border sections of the crossing, which are monitored by sensors 16 or 17 for monitoring the passage of the train and their subsequent release, the calculating devices 27 or 28 send the shaper 21 a command to translate the barrage devices 25 into the normal (lowered) position, the barriers 24 rise to the vertical open position, then commands are formed to turn off the red lamp of the traffic lights 22 and turn on the moon-white light on them, turn on the inhibit signal at the obstruction light 26, as well as Turning the acoustic alarm 23. In the display device 30 from the device 19 forming a closed moving countdown time is commanded to turn off the time display, then the crossing is considered open, and are allowed passage of motor vehicles.

The driver 21 of the control signals compares the incoming commands from the computing devices 27 and 28. If they are identical, they are executed. In the event that a command comes from one calculating device to turn on the red lamp of the crossing traffic light 22 (the device 18 for monitoring the crossing zone has detected an object in the closed crossing zone), and from another, a command to turn on the moon-white light of the traffic light (device 18 has not detected object) - the command to turn on the red traffic light is executed, an error signal is transmitted to the counting devices 27 and 28 in a feedback manner.

In the process, the diagnostic device 20 checks the regular operation of all devices and registers all the information in the event archive, in the event of a failure of one of the system units, the diagnostic device 20 generates data about the malfunction and transfers them to the automated remote control 3 on duty.
