Train cab interlocking and mutual-controlling system based on train line

Abstract

The invention provides a train cab interlocking and mutual-controlling system based on a train line. The system comprises one train line which penetrates through a train; a cab is internally provided with a key switch, a key relay, a key interlocking relay and an occupation relay, wherein the key switch, a normally-closed contact of the key interlocking relay and the key relay are connected in series and then are switched into a train power grid; the key switch, a normally-opened contact of the occupation relay and the normally-closed contact of the key relay are connected in series and then are connected with the relay in parallel, all of the members are connected with the normally-opened contact of the key relay in series and then are switched into the train power grid; and the train line is connected with a lead wire between the occupation relay and the normally-opened contact of the key relay. The system provided by the invention has an ingenious concept and the interlocking and the mutual-controlling of the cab can be realized by only using one train line, so that the system is beneficial to simplifying design and construction and improving the reliability; according to the system provided by the invention, not only the interlocking and the mutual-controlling of keys of the two cabs in the train are realized, but also the interlocking and the mutual-controlling of the keys of any two cabs can be realized when random arrays of the trains are coupled.

Description

technical field

[0001] The invention relates to an interlocking and mutual control system for a train driver's cab, in particular to an interlocking and mutual control system for a train driver's cab based on a train line. Background technique

[0002] In the current subway trains, each row has a driver's cab at the front and rear ends, and several carriages in the middle (such as the Nanjing subway has 6 carriages per row). When the driver operates the train, the key of the driver's cab is unlocked and the driver's cab is activated before other operations can be performed. If the train is in normal operation, the driver's cab at the other end is also activated with a key, which may cause multiple driver's cabs to operate the train at the same time, which will cause the train operation order to be disordered and malfunction, and even cause serious accidents.

[0003] Therefore, in the design of the train control circuit, it is necessary to design a mutual control circuit fo...
