Description

The device relates to the device.m of automation and telemechanics in railway transport, ensuring the safety of train traffic and increasing the capacity of the line.

It is known that the spanning stop control device contains rail circuits without insulating joints with connected rails at the transmitting and receiving ends of matching elements to which the output of the sensor of impulses and track receivers 1 are connected respectively.

A disadvantage of the known device lies in the reduced reliability, which is associated with the dispersion of equipment over the stage and difficulties in the maintenance and preventive maintenance of the device.

To increase the reliability of the device, the proposed device is equipped with a number of transmitting ends in matching blocks, two inputs of each of which are connected respectively to the outputs of track receivers of adjacent rail circuits, the third input is connected to the output of the pulse sensor, and the outputs are connected to track relays.

The drawing is a block diagram of the proposed device.

It contains track circuits 1-6 without insulating joints with matching connectors 7-10 of the receiving end and matching elements 11, 12 and 13 of the transmitting end connected to the rail.

To the matching elements 7-10 connected track receivers 14-17, and to the matching elements 11, 12, 13 - sensor 18 pulses.

Outputs of track receivers 14-17 are connected to blocks 19. 20, 21 matches, the output of which includes track relays 22, 23, 24. All equipment is located in station rooms 25 and 26 of stations 27, 28, limiting the stage. Insulating joints 29 and 30 are installed at the boundaries of the haul. At the stations, the information exchange units 31 and 32 and the control unit 33 are installed.

The device works as follows.

The sensor 18 pulses produces pulses at its outputs. Driving is considered free only if all traveling relay 22, 23, 24 is driven. Consider the case of freedom of the haul. When a pulse is output from the output of the sensor 18 pulses connected via cable lines to matching elements 11 and 13, the track receivers 14-17 are activated and connected to the matching elements 7-10. At the same time, the blocks 19 and 21 of the coincidence give output pulses to the traveling relays 22 and 24 (there is a single signal on all three inputs of each of blocks 19 and 21). When a pulse is output from the output of the sensor 18 pulses connected via a cable line to the matching element 12, the track receivers 15 and 16 are connected to the matching elements 8 and 9. At the same time, the coincidence unit 20 outputs the output pulse to the track relay 23 (for all three inputs of the coincidence unit 20, a single signal is present). Each of the track relays 22, 23, 24 is energized in a pulse, and in the interval, the front contacts of the track relays do not open due to slowing the track relays 22, 23 and 24 to fall off. In the presence of a train on the stretch of at least one of the track relays 22, 23, 24 will be de-energized. For example, when a train is on track circuit 2, the coincidence unit 20 will not output an output signal and the track relay 23 will be de-energized. The control unit 33 solves the problem of monitoring the presence of pulse signals at the outputs of the sensor 18 pulses. When the operation of the pulse sensor 18 is abnormal, for example, when a continuous signal appears on one of the outputs, the control unit eliminates the possibility of false control of the free span. Information exchange lines and information exchange blocks 31 and 32 solve the problem of changing directions, and also transmit information to the station of departure about the arrival of a train to a neighboring station. Claims device of the span control, containing rail values without insulating joints connected to the rails at the transmitting and receiving ends of matching elements, to which the output of the pulse sensor and track receivers are connected, respectively, in order to increase reliability the number of transmitting ends by matching blocks, two inputs of each of which are connected respectively to the outputs of track receivers of adjacent rail circuits, the third input is connected to the output of the sensor mpulsov and outputs are connected with travel switch.
