Description

(54) DEVICE OF INTERVAL REGULATION OF TRAIN TRAFFIC

Ki 19 is enabled repeater 24 of the track relay 6.

The current track relays 25 of the proximity circuit are connected to the outputs of the resonant amplifiers 20 through parallel-connected own front contacts 26 and front contacts 27 of repeaters 24 of the track relay. The track circuits 1 and 2 are additionally fed by a frequency modulated frequency converter 28.

The device works as follows.

When the rail circuit 1 is free, the current of the frequency converter 28 induces 16 electromotive force in the traveling coils. mutual induction. The signals from these coils are fed to the inputs of the corresponding resonant amplifiers 17 and then to current track relays 18, by triggering which you can determine the location of the tail of the train leaving the platform. Thus, the use of current track receivers at the station tracks eliminates the isolation joints. Similarly, the elimination of insulating joints at advance signals is achieved. The signals on the track coils 19 are amplified by the corresponding resonant amplifiers 20 and through the contacts of the repeaters of the track relay of the approximation rail circuit and the own contacts of the current track relays are fed to the excitation winding of the current track relays 25. Parallel connection of the contacts 26 and 27 excludes the possibility of the corresponding current path relay to operate the cause of a double shunting, since if the train has already followed the rail circuit 2, approaching it and slamming you sotvetstvuet current travel of the coil, then again last excitation occurs only when the full release train

track circuit 2, which is fixed at each advance signaling point by repeaters 24, which receive power through link 21 via front contact 23 of track

relays 6. The current track relays 18 carry out the same dependencies in the linear circuit for controlling the advance signals as the corresponding path relays in known systems.

Frequency converter 28 does not affect the operation of track circuits 1 and 2, since its frequency is different from the frequency of the power supply of track circuits.

Subject invention

An interval train control device containing rail circuits — stationary and approximation — each of which consists of a power source

one end and a track relay at the other and is separated from the other by traveling signals, while inside each track circuit there are installed travel coils connected via resonant amplifiers to current traveling

relay, and along the approximation track circuit there is a communication line, in which, for each track coil of the approximation track circuit, a track relay repeater is connected via the front contact of the track relay of the same

rail circuit, and the track signal separating rail circuits — stationary and approximation — has a track converter connected to these rail circuits, characterized in that, in order to exclude

the effect of double shunting, current travel relays of the approximation track circuit are connected to the resonant amplifiers via parallel-connected front contacts - their own and corresponding repeater of the track relay.
