Abstract

The invention provides a protection section unlocking method and system. The protection section unlocking method comprises the steps that a vehicle-mounted controller obtains the state of a railway vehicle and sends the state to a region controller; the area controller receives the railway vehicle state and sends the railway vehicle state to the computer interlocking device; when the railway vehicle is in a stable and accurate parking state, the area controller retracts the movement authorization to the front of the signal machine; the computer interlocking equipment judges the connection state with the area controller; if the connection state of the computer interlocking equipment and the area controller is normal, the state of the railway vehicle is received; and when the state of the railway vehicle is a stable and accurate parking state, the computer interlocking equipment carries out protection section unlocking operation. According to the protection section unlocking method and system provided by the invention, through information transmission among the vehicle-mounted controller, the area controller and the computer interlocking equipment and advanced processing of transfer authorization, the protection section can be safely unlocked, and the safe operation of the railway vehicle is improved.

Description

technical field [0001] The invention belongs to the field of rail transit, and in particular relates to a protection section unlocking method and system. Background technique [0002] The protection zone unlocking scheme of the prior art does not fully consider the delay between the zone controller and the computer interlocking device, the zone controller and the on-board controller, and the delay between the computer interlocking device and the on-board controller, which affects the safety of the rail vehicle. drive. SUMMARY OF THE INVENTION [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a method and system for unlocking a protection section, which enables the protection section to be unlocked safely through the information transfer between the vehicle-mounted controller, the area controller and the computer interlocking device and the advance processing of the mov...
