Vehicle-mounted equipment and train communication system

Abstract

The invention discloses vehicle-mounted equipment and a train communication system and belongs to the technical field of train control. By adoption of the vehicle-mounted equipment and the train communication system, the technical problem that the operation efficiency is low when a train passes through a ZC (Zone Controller) boundary zone under the condition that only one wireless communication device is usable is solved. The vehicle-mounted equipment comprises a wireless communication device, a time management device, a storage device and a processing device, wherein the wireless communication device is used for receiving switching instructions from a ground transponder; the time management device is used for determining wireless overtime time slices after the wireless communication device receives the switching instructions from the ground transponder; the storage device is used for storing communication contents with a receiving ZC when the wireless communication device stops communication with the receiving ZC; the processing device is used for determining a next movement authority according to the communication contents with the receiving ZC, judging whether the current movement authority is connected with the next movement authority, and carrying out zone switching when judging that the current movement authority is connected with the next movement authority.

Description

technical field [0001] The invention relates to the technical field of train control, in particular to a vehicle-mounted device and a train communication system. Background technique [0002] With the rapid development of urban rail transit, the wireless communication-based train control system (Communication Based Train Control, referred to as CBTC) has been more and more widely used. Zone Controller (ZC for short) is the core subsystem of the CBTC system. It calculates for each communicating train based on the precise position reported by the communicating train and the axle occupancy / idle, turnout and signal machine status reported by the interlock. Movement Authorization (MovementAuthority, referred to as MA), controls the safe operation of the train. [0003] In a long line, multiple ZCs are generally arranged. During the train running process, the train and trackside information is exchanged between the two area controllers to jointly control the train to pass through...
