Description

The invention relates to railway automation and telemechanics, and in particular to means of automatic traffic control at level crossings, allowing to close the level crossing depending on the coordinate, speed and acceleration of an approaching train.

Known control devices for crossing signaling in which the control of the fence is carried out taking into account the coordinates, speed and acceleration of an approaching train (patents RU 2281219, RU 2342274, US 2011095139, predictors НХР-3, PMD-3 (Internet resource http: //www.getransportation .com / rail / rail-products / signaling-a-communication / crossing-control / highway-crossing-processor-with-phase-motion-detector-hxp-3pmd-3.html)). In these devices, rail circuits powered by alternators are used, where according to continuously monitored parameters of voltage, magnitude or / and phase of the signal current at the supply end, it is judged that the train occupies the approach section and the parameters of its approach to the move (distance, speed, direction of movement and time of arrival to move).

The disadvantages of the known devices are the limited length of the approximation section at low values of ballast resistance, insufficient reliability and the inability to use on inactive areas where there are no electrical joints in the rail lines.

A safe railway crossing control system is known, comprising a GPS receiver mounted on a train and ground-based wireless communication devices transmitting GPS-based location information and including an alarm unit warning of a dangerous situation at a railway crossing. The railway crossing system includes a route detection sensor that detects movement in the direction of the railway crossing, and a wireless communication device that transmits a traffic signal using a wireless route determination sensor. The central control system transmits information about the location of the moving train to the railway crossing, warns the train about a dangerous situation. An additional control unit for the control room connected with the central control system transmits the detected signal about the movement to the central control system and transmits information to the moving train (KR 100678729, B61L 29/02, 01/09/2007).

The disadvantages of the known control system are the inability to control the integrity of the composition at the crossing and the long closed time of the railway crossing.

As a prototype, a device for controlling traffic at a railway crossing was selected, which provides for the use of two rail chains of the approach and removal sections on both sides of the railway crossing and, on each railway track of the railway crossing, the installation of track sensors for tracking wheelsets of trains on the rails, while the outputs of the count sensors the axes through the signal processing unit are connected to the corresponding inputs of the control and control unit of the crossing signaling, the power outputs of They are controlled by actuators of the crossing fencing equipment, and a crossing transceiver is used at the crossing, the data port of which is connected to the data port of the control and control unit of the crossing alarm system, while the traveling transceiver is connected via a digital radio channel to the transceiver of the locomotive's onboard control device (patent RU 2468949, B61L 23/16, B61L 1/16).

In the device, the switching on and off of the actuating devices of the moving is carried out as a result of the train acting on the rail chains and axle counting units. Rail chains continuously monitor the location of the train on sections of the track adjacent to the crossing, and control its coordinates on the approach section, and axle counting devices allow you to record the moments of release of sections of the track directly behind the crossing to accelerate the opening of the barrier after the train is tracked.

The disadvantages of the device are the impossibility of use in areas of low activity, where there are no electrical joints in the rail lines, as well as the dependence of the maximum possible length of the approximation section on ballast resistance.

The technical result, the achievement of which this invention is directed, is to increase the length of the approaching area and expand the functionality, which consists in providing the possibility of use on inactive sections of roads.

The technical result is achieved by the fact that to the crossing signaling control device, which contains in the immediate vicinity on both sides of the railway crossing on each railway track two axle count sensors for detecting the trace of the train wheelsets, while the sensor outputs are connected to the inputs through the signal processing unit block of control and management of the cross-country alarm, the power outputs of which are connected to the corresponding inputs of the actuating devices of the crossing barriers, and the bottom data port of the monitoring and control unit is connected to the port of the track transceiver via a digital radio channel connected to the transceiver of the on-board control device of the locomotive according to the invention along a rail line along a train along an approach section at some distance from each other, for example, on posts along a railway track , set passive tags with fixed coordinates, each of which has its own individual identification number, and on the locomotive poured associated reader, the output of which is connected to one of the inputs of controller onboard control device, to one input of which is connected as output locomotive speed sensor.

The drawing shows a structural diagram of a control device crossing the alarm system.

The device contains on each railway track from two sides of the crossing 1 on the rail lines 2 two sensors for detecting the tracking of wheel sets 3 trains 4, which are connected through the signal processing unit 5 to the inputs of the control and control unit of the crossing signaling 6, the power outputs of which are connected to actuators means of moving fencing 7. The input data port of the monitoring and control unit 6 is connected to the port of the track transceiver 8 through a digital radio channel 9 connected to the transceiver 10 on-board about the locomotive control device 11. Along the rail line along the train in the approach and removal section, at some distance from each other, passive tags 12 with fixed coordinates are installed, each of which has its own individual identification number, a locating device 13 is installed on the locomotive, the output of which connected to one of the inputs of the controller of the on-board control device 11, to one of the inputs of which the output of the locomotive speed sensor 14 is also connected.

The control device crossing the alarm works as follows.

When preparing each train 4 for departure on the route, data on all identification tags 12 and their coordinates, as well as the location coordinate of the next and subsequent crossings 1 and code addresses for communication with its track transceiver 8 are entered into the electronic memory of the controllers of the onboard control device 11 trains 4 together with the assignment of the route of movement. When reading the first identification mark 12, the radio channel 9 for connecting the locomotive with the crossing alarm equipment is activated, the updated information about the distance of this mark to the move is entered into the controller of the locomotive, and at the same time, in accordance with the readings of the speed sensor, the distance traveled is calculated and the current coordinates of the train are determined relative to the move, which are transmitted via digital radio channel 9 and received by the controller of the control and management unit of the crossing signaling 6 The controller of automatic crossing signaling according to the coordinates of the train, taking into account the speed of their change by software, determines the time of arrival of the train to move and with the necessary dependencies issues commands to control the fencing and signaling equipment. The release of the move is fixed by the equality of the number of axes counted by the counting devices installed before and after the move.

In this device of the cross-country alarm system, the length of the approximation section is determined by the range of the radio channel, which at the current level of technology is at least 5-30 km, and the number of installed tags and can be practically any.

Thus, in the proposed control device crossing the alarm system provides an increase in the length of the approximation section to any desired values, and the device can be used both on inactive sections of railways without electric traction, where there are no electrical joints in the lashes of rail lines, and on highways, including including electric traction of any kind, not equipped and equipped with means of automatic blocking of any type.
