Abstract

The invention discloses a multi-channel double-redundancy rail transit vehicle reconnection system and a reconnection method. The system comprises reconnection gateways, wherein each train has two cabs, and each cab is provided with a reconnection gateway; all internal subsystems of the train are correspondingly connected with two reconnection gateways through the in-vehicle CAN bus; all subsystems are also connected with the two reconnection gateways through the in-vehicle Ethernet bus correspondingly; when the two trains are reconnected, each reconnection gateway of any one train is connected with all the reconnection gatewayes of the other train; when the two gateways which do not belong to the same train are connected, and the first CAN reconnection bus and the second CAN reconnectionbus are connected between the two gateways. The system has the advantage of high reliability.

Description

technical field [0001] The invention belongs to the technical field of vehicle network control, and in particular relates to a multi-channel dual-redundant rail transit vehicle reconnection system and a reconnection method. Background technique [0002] CAN bus is a serial communication network that supports distributed control and real-time control systems. It has reliable real-time and flexibility, and is widely used in industrial control, automobile and rail transit and other fields. Ethernet has the characteristics of a large amount of communication data, and is widely used in multiple subsystems of rail transit vehicles. The electrical system of a rail transit vehicle is composed of multiple subsystems, such as PIS system, door system, etc. These subsystems generally form a train-level bus of Ethernet + CAN bus (backup) for communication control. At present, when two rail transit vehicles are reconnected, the reconnection gateway needs to realize the mutual communicati...
