Description
Technical Field

Background
Urban rail transit currently commonly employs a train control over train communication (CBTC) system based on vehicle-to-ground communication, and is developing a next-generation signal system based on vehicle-to-vehicle communication.
For the CBTC system, when wireless communication between the train and the ground fails, the system is degraded to an interlocking or (point type ATP/ATO) mode operation. At the moment, the system depends on a ground interlocking system to complete interlocking logic operation and forward movement authorization calculation required by point type ATP (automatic train protection) by acquiring information such as zone occupation, clearance and the like output by the axle counting equipment, and an active responder sends point type movement authorization information to the vehicle-mounted controller.
When the train-car communication system is normal, the train route control adopts a strategy which takes the vehicle-mounted equipment as a control main body and a core and takes line resource management as a basis, and the vehicle-mounted control unit is responsible for completing the train route control and the mobile authorization calculation without interlocking logic processing by ground interlocking equipment. When the train-to-train communication system fails, the operation must be degraded because the train cannot acquire the forward access resource information from the trackside target controller through the train-to-ground communication link. At the moment, the existing vehicle-vehicle communication system adopts a strategy similar to the traditional CBTC system, and the ground target controller is responsible for completing the access interlocking logic operation (and point MA terminal point calculation) according to the information of section occupation/clearance and the like collected by the axle counting equipment.
The above-mentioned train route control in the normal mode and the degradation mode needs two different processing bodies, namely, the on-board processing body and the trackside processing body, to complete, and the purpose of simplifying the function of the ground equipment cannot be achieved.
