Route control method under communication based train control system and relevant equipment thereof

Abstract

The invention provides a route control method under a communication based train control (CBTC) system and a relevant equipment. A route is unlocked after a signal crossing information transmitted by a ZC is received and a starting end signal of the route is normally closed. A situation that a non-CBTC level train does not cross the starting end signal is excluded from the information transmitting opportunity; therefore, under the situation that the non-CBTC level train does not cross the starting end signal, a CI (Computer Interlocking) system cannot execute route unlocking on the route with the advancing of a train in the route so that the safety of the system is improved. And moreover, as the end point of movement authority cannot cross the starting end signal and the CI system unlocks the route under the situation that the starting end signal of the route is normally closed and the signal crossing information is received, the route for executing route unlocking cannot be open for the train outside the starting end signal and the train outside the starting end signal cannot enter routes open for other train by mistake; therefore, the availability of the system is improved.

Description

technical field [0001] The present invention relates to the technical field of communication-based train control systems, and more specifically, relates to a communication-based down-route control method of a train control system and related equipment. Background technique [0002] CI (Computer Interlocking, Computer Interlocking) system is a signal system to realize station interlocking. The CI system forms signal equipment such as signal machines, trackside train occupancy detection equipment, and turnout detection equipment within the control range into a system that is both interconnected and mutually restrictive. interlocking relationship and control it. [0003] In the existing CI system, the CI system handles train routes of different natures for trains of different control levels by receiving the signal machine on and off command information sent by ZC (Zone Controller), such as CBTC (communication-based train Control (CommunicationBasedTrainControl) control-level t...

Problems solved by technology

There are two cases in this judgment method. In the first case, due to the uncertainty of the train position, the actual body of the train may not be pressed into the route when ZC sends the information of the cross-pressure of the signal machine. There are other trains, the train on the outside of the signal at the start end is downgraded from CBTC level to non-CBTC level, and the train on the inside of the signal at the start end will move forward, which will cause the first section of the route to be idle. At this time, the CI system controls the first section to unlock , if there is a turnout in the first section, the turnout can also rotate with the unlocking of the first section. If the train is about to enter the turnout at this time, it will be dangerous

[0005] In the second case, if the train at the CBTC control level disconnects the communication with ZC before entering the route, because ZC judges that the train-ground communication delay exists, when ZC judges that the train-ground communication is interrupted, the train may have completely entered the route, but this When the ZC does not send signal cross-pressure information to the CI system according to the action of the train

The route originally processed for the train inside the signal at the beginning can be used by the train outside the signal at the beginning. The effect of the route is inconsistent with the original intention of the control, and there is a usability problem
