Description

FIELD OF TECHNOLOGY

The claimed device relates to a means for controlling a railway (railway) crossing, in particular, an alarm system installed in areas of intersection of road traffic with railway crossings, preventing the activation of devices that block the passage of vehicles.

BACKGROUND

Currently, crossing closure is determined by the length of the approach section and the maximum speed of the moving unit, without using a predictor of the closing time of the crossing, such control is not optimal.

A known method of controlling the closure of a level crossing (patent US 8297558, 10.30.2012), which consists in using a device to predict the time of approach of a train to a level crossing. This solution is based on the system of interval regulation of trains, however, the speed of a train is determined solely by the indication of a traffic light, meaning the color indication of a lighted lamp, green, yellow, red and various combinations depending on the type of interval regulation of train movement and the passing traffic light. The indications of the passing traffic light vary depending on the state of the rail circuit located in front in the next block section. So, the existing system of interval regulation of trains limits the speed of a train along a block section (rail circuit) by changing the indication of a traffic light. Any system of interval regulation of trains uses a traffic light to limit the speed of the train or stop it completely. Speed limits are prescribed by rail regulations. For example, for a three-digit blocking, there are norms: green — passage block of the section without speed reduction, with the maximum allowed in this section, yellow — block passage of the section at a speed of not more than 60 km / h (one block section is free), red — complete stop before traffic light. Using the indications of the passing traffic light, as well as the indications of the automatic locomotive signaling system (ALS), it calculates the closing delay for moving.

The disadvantage of this solution is that the time delays calculated in advance are limited by the number of traffic lights, i.e. if there are three indications of a traffic light, then there are three values of the delay time for closing the crossing. The known system uses the indications of the passing traffic light, as well as the readings of the ALS system which are associated with the speed of the train only indirectly. The train speed is not directly controlled. At the same time, the block closing time prediction block included in the known system does not use the reference parameters (permissible values) of the rail circuit, and therefore, this system does not allow determining the exact time for the optimal delay in closing the railway crossing.

DISCLOSURE OF A USEFUL MODEL

The objective of the claimed device is to eliminate existing shortcomings in determining the actual speed of the railway train for accurate calculation of the activation time of the alarm at the crossing and its closure based on the calculation of the delay time for closing the railway crossing.

The technical result is to increase the accuracy of determining the time of approaching the train to move and reduce downtime of vehicles when blocking the railway crossing.

IMPLEMENTATION OF A USEFUL MODEL

In FIG. 1 shows a general diagram of a device for predicting the closing delay time of a railway crossing 100. The device 100 comprises a main computing circuit, which includes at least one microcontroller 101 and one or more memory means 102, for example, RAM and / or ROM and / or flash memory, etc.

At the input of the unit for collecting information and determining the state of the rail circuit 103, primary information is received, such as voltages U and current strengths I in an arbitrary coordinate for any length of the rail line, depending on the values of voltages and currents at the beginning or end of it. Block 103 determines the voltage and current strength at the supply end of the rail line and the area of approximation of the rail line in the shunt mode.

Block 104 performs the determination of the coordinates and speed of the rolling stock, and receives an input signal from the information collection unit 103, about the detection of the area of approximation of the rail line in the shunt mode,

The data storage unit 105 on the permissible values of the shunt mode of operation of the rail circuit contains data on the permissible values of the parameters of the rail circuit in sections of the rail line. These parameters are standard and may differ for each control section of the rail line. Block 105 may be implemented as a database embodied on a storage device, for example, an HDD disk, SSD disk, optical disks, flash drives, a memory card, and the like.

The block for calculating the closing delay time of the railway crossing 106 is configured to compare the parameters obtained from the coordinate and speed determination unit of the rolling stock 104 and the data storage unit 105 for the mentioned section of the rail line approximation in the shunt mode and determining the value of the moving closing coordinate. At the output of block 106, the value of the railway exit closure coordinate is calculated, which is transmitted to the exit closure control unit 107. Block 107 activates automatic signaling devices based on the value of the coordinates for closing the move received at the input.
