Device and method for safe route release based on train authorization

Abstract

The invention relates to a device and a method for safe route release based on train authorization. The device comprises interlocking subsystems and a region controller. Mutual information exists between the interlocking subsystems and the region controller. The interlocking subsystems transmit train route identifiers to the region controller, and take part in train movement authorization. The region controller transmits train position information to the interlocking subsystems, and takes part in controlling of train route release. Compared with the prior art, the device and the method are advantaged in that movement authorization is brought into a release mechanism, an interlocking relationship between route release and route use conditions of a train is established, and route release safety is guaranteed.

Description

technical field [0001] The invention relates to the signal interlocking field of high-speed railways, ordinary railways and urban rail transit lines, in particular to a safe access unlocking device and method based on train authorization. Background technique [0002] At present, the mainstream of the subway is the train control system based on communication technology (CBTC), which realizes mobile blocking technology through uninterrupted two-way communication between on-board equipment and trackside equipment. Realization, the movement authorization management of the train is realized by the zone controller (ZC). [0003] The traditional approach unlocking method adopts the method of unlocking the approach in sections after the trains pass through the approach in sequence by the interlock detection. Since the CBTC system adopts the mobile blocking technology, the train can be closely tracked, and the communication transmission has the possibility of delay and asynchrony, ...

AI Technical Summary

Problems solved by technology

Since the CBTC system adopts the moving block technology, the train can track and run closely, and there is a possibility of time delay and asynchrony in communication transmission, which means that information such as the status of each trackside equipment and the status of the route changes in different subsystems. There will be differences. When two trains are running closely at high speed, and the interlock detects that the vehicle in front has crossed the signal machine and cleared the first section inside the signal machine, it will start the route unlocking, while the zone controller lags behind to obtain the signal machine prohibition. state, if the rear vehicle has been authorized to enter the route, the operation of the rear vehicle will be affected during the sequential driving and unlocking process of the vehicle in front, resulting in emergency braking of the rear vehicle

It is unscientific to adopt the traditional way of unlocking the way, and it cannot meet the needs of the growing industry.
