Description

The invention relates to railway control and measuring equipment and can be used for automatic control of train movement parameters from a control room in order to ensure safety management of their movement on a controlled section of the railway.

A known method for a similar purpose, according to which the operational control of rolling stock of trains is carried out from a control center in a semi-automatic mode / USSR Author's Certificate No. 263286, Cl. B61L 27/04, 1970 /.

The disadvantage of this method is the lack of information at the control room about the speed characteristics of trains, which does not adequately ensure the safety of train traffic on a controlled section of the railway.

There is a method of operational control of the safety of train traffic on a railway section, which consists in measuring the speed characteristics of train movements using track, speed and time sensors and processing and storing the information received from the sensors. / RF patent No. 2238869, Cl. B61L 25/02, 2004 /.

This method is adopted as a prototype.

In the prototype, the processing and storage of information is carried out directly on the train. In addition to the track and speed sensors on the train, there are temperature and pressure sensors, signaling respectively the excess of temperature in the salons of the train cars and the pressure in its brake system. There are also time sensors and status sensors for the electrical circuits of the cars.

The listed sensors make it possible to ensure the safety of train traffic by providing the operator with timely information about the speed characteristics of the train and the state of its braking and high-voltage systems, as well as the temperature in the train salons (for monitoring an imminent fire).

The disadvantage of the prototype is the inability to control the geometry of the rail track, which determines the safety of train traffic. Also, there is no transfer of information received from the sensors to the control room for timely correction of the speed characteristics of the movement of trains following the train that first received information about the state of the rail track.

The technical result obtained from the implementation of the invention is to eliminate the disadvantage of the prototype, i.e. improving the safety of train traffic by monitoring the geometry of the rail directly from the train and by transmitting the received information about the state of the rail to the control center.

This technical result is achieved due to the fact that in the known method of operational control, which consists in measuring the speed characteristics of train movements using speed, path and time sensors, followed by processing and storage of the obtained information, the acceleration of non-sprung elements of train carts in the directions orthogonal to them is additionally measured traffic, and the processing and storage of information received is carried out at the control center, from which information on the optimal speed characteristics teristics motion on a controlled portion of the railroad communication system is routed to the train.

The acceleration of the non-sprung elements of train bogies in directions orthogonal to the direction of their movement is measured using a two-component accelerometer.

The communication of the control center with trains is carried out over the air.

As a result of various natural or man-made phenomena, for example, in the Far North, the given geometry of the rail track can undergo distortion, which poses a direct threat to the safety of train traffic.

For operational control of rail track geometry on trains, in addition to speed, track and time sensors, sensors for two acceleration components of non-sprung elements of train carts orthogonal to their direction of movement are additionally installed. (It is possible to install one two-component acceleration sensor).

Acceleration sensors working in the vertical direction respond to subsidence of the rail threads, and acceleration sensors working in the horizontal direction react to the deviation of the rail gauge from the width standards.

All sensors and equipment used on trains have no special features. (Acceleration sensors are conventional accelerometers). A central processor with or without a train automatic driving system (as in the prototype) is located at a control room provided with a train communication system. There, the received information is stored in the corresponding storage device.

The information received from the acceleration, speed, track and time sensors is pre-processed directly on the train. Then, through the radio channel, the information is sent to the control center, where it undergoes final processing in the central processor.

After decoding the information, the latter, if necessary, is sent to the following trains to adjust the speed characteristics of their movement.

Thus, the central computer accumulates information about the geometry of the rail track on a controlled section of the railway from all trains following the first, since all trains are equipped with the equipment described above. At the same time, the optimal speed characteristics of the movement of trains on a controlled section of the railway are set from the control room.

If the amount of distortion of the geometry of the rail track on the controlled section of the railway will pose a direct threat to the safety of trains, a command will follow from the control point to stop the movement of trains on the controlled section of the railway until the emergency is eliminated.

Thus, this technical solution allows to increase the safety of trains on a controlled section of the railway by transmitting information about the geometry of the rail track received from the train to the control room and adjusting the speed characteristics of the movement of trains from the control room.

This achieves the set technical result.
