Abstract

The invention relates to railway automation and telemechanics, in particular to the control of the arrival of the entire train at the stopping point. The purpose of the invention is to increase the capacity of railway sections. The method of controlling the arrival of the entire train consists in magnetizing the wheels of the last car of inverse polarity with respect to the rest of the wheels of the previous car and fixing the last car when arriving at the wheels magnetized with reverse polarity. 1 il.

Description

The invention relates to railway automation and telemechanics, in particular to the control of the arrival of the train in full strength at the stopping point.

The purpose of the invention is to increase the capacity of railway sections.

The drawing shows a block diagram of the device, realizing the proposed method.

The device contains a power source 1 connected to one of the inputs of the information recording unit 2, output connected to an electromagnet 3. Magnetic sensor 4 is connected to the input of information reading unit 5, outputs connected to one of the inputs of control unit 6, the other inputs of which are connected with. units 7 station automation, one of the outputs of block 6 is connected to other inputs of block 2, and the other outputs of block 6 are connected to block 8 of the display. The train travels through sections 9 and 10 of the departure station and 11 and 12 of the receiving station.

The device works as follows.

In the initial state with free sections 9-12, the signals at the outputs of the magnetic sensor 4, blocks 2 and 5, respectively, of the recording and reading of information are missing and are zero. The power supply 1 by means of the switching elements of the unit 2 is disconnected from the electromagnet 3 and a permanent magnetic field is not created in the zone of its action. From the outputs of block 7, information signals are sent to the inputs of control block 6 about the state of sections 9-12, as well as about the presence of established shunting and train routes for sending and receiving through these sections. From the outputs of the control unit 6, the inputs of the information recording unit 2 and the inputs of the indication unit 8 receive control signals that disconnect the source 1 from the electromagnet 3 and signal the device to be ready for operation. The control unit 6 is in the state of "waiting for the busy signals of sections 9-12.

The arrival of the information signal about the occupation of the section 10 (12) by the sending train from the outputs of block 7 to the inputs of block 6 of the control leads the latter to the HSP.

This causes the appearance at the outputs of block 6 connected to other inputs of block 2 of recording information of control signals causing the connection of source 1 to electromagnet 3.

Thus, in the zone of action of the electromagnet 3, a constant magnetic field of "direct polarity" is created, causing the magnetization of passing train wheel pairs above it.

At the moment of the release of the last wheelset of the last car of section 9, the state of the outputs of block 7 changes, which is fixed by control block 6, which provides control signals to the inputs of block 2 of information recording, re-switching the source poles 1. Therefore, in the area of electromagnet 3 a constant magnetic field is created which will now magnetize the passing wheel pairs with the reverse polarity.

To provide reverse magnetisation of at least two or more wheel pairs of the last car, it is necessary to install electromagnet 3 at a distance, for example, less than or equal to the minimum possible length between the car’s outermost axles, from the border of sections 9 and 10 (11 and 12) . After the train 10 (11) clears the train, the magnetization mode ends and the device returns to its original state.

Reception of full train trains with pre-magnetized wheelsets is monitored as follows.

The passage of each wheel set above the magnetic sensor 4 causes the appearance of

at its output is an emf whose phase depends on. polarity (direction) of a constant magnetic field created by wheel pairs. As a result, signals are output from the output of the information reading unit 5 to the control unit b informing about the passage of the wheelset over the magnetic sensor 4 and about its polarity. This allows you to organize axle counting and wheel arming.

pairs belonging to the last car.

At the moment of the release of the train by section 10 (11), the control unit 6 transmits to display unit 8 information about the presence of the last car in the received train, which is accompanied by audible and visual alarms. The device returns to its original state. In this way, the entire train arrival is identified.

Invention Formula The method of controlling the arrival of the entire train, which is forgiving the stretch, consists in fixing the track of the end of the train by reading pre-applied magnetic tags from its last 5 cars, characterized in that, in order to improve the accuracy, magnetic fields of the latter are used as magnetic tags the opposite polarity of magnetization of at least one more car of the train; after reading the tags from the wheels of the last car, their phase is determined and compared with the phase of the tags, GOVERNMENTAL with the wheels of another car, and the results of the comparison is judged on prosledovanii end composition. 12. 0
