Problems solved by technology
If the CI fails to receive the stop signal due to the train itself or other reasons, the protection section cannot be unlocked, which reduces the availability of the system
Moreover, the route protection section cannot be unlocked during the operation of the train, especially when there is a turnout section in the route protection section, the turnout can only be handled after the train stops and the unlocking of the route protection section is completed. The other side of the approach reduces the system efficiency

The embodiment of the present invention provides a method and system for unlocking the route protection section. Based on the CI actively requesting the route protection section to be unlocked, when the CI fails to receive the stop signal due to the train itself or other reasons, resulting in When the protection section cannot be unlocked, the access protection section can still be unlocked, which improves the usability of CBTC. Moreover, even when the train is running, the unlocking of the protection section of the station can be realized, which further improves the usability of the CBTC.
Description
technical field [0001] The present invention relates to the technical field of rail traffic control, and more specifically, to a method and system for unlocking an approach protection section. Background technique [0002] In the communication-based train operation control system (Communication Base Train Control, CBTC), the train and the ground realize two-way real-time communication between the train and the ground through wireless communication. Real-time communication between ground signal equipment is realized through wired communication. The zone controller (Zone Controller, ZC) sends movement authorization to the train under its jurisdiction according to the current position of the train, signal machine display and other factors. In order to meet the precise parking requirements of the train, fully considering factors such as the braking distance of the train and the line, a protection zone is set after the stop point, that is, one or two sections behind the approach...
