Abstract

The invention relates to a rail transit communication gateway and a data transmission method thereof. The rail transit communication gateway comprises a processor core board, a network communication network port and a data communication interface. Wherein the processor core board is used for realizing data transmission between the vehicle-mounted equipment and a train communication network according to a TSN protocol. The processor core board realizes data transmission with a train communication network through the network communication interface; and the processor core board realizes data transmission with vehicle-mounted equipment through the data communication interface. On the basis, the rapid processing of the vehicle-mounted TSN communication data is realized, the requirements of the rail transit Ethernet on the TSN are met, and the rail transit communication performance is improved.

Description

technical field [0001] The invention relates to the technical field of rail transit communication, in particular to a rail transit communication gateway and a data transmission method thereof. Background technique [0002] Based on the continuous improvement of high-speed railway's requirements for train network systems, especially modern trains are equipped with more and more intelligent subsystems to achieve higher performance, safety, lower energy consumption and high comfort requirements. brought many challenges. [0003] At present, the network exchange requirements in trains mainly include: (1) The core components of train operation management, such as data exchange of traction, braking, lighting, batteries, heating, ventilation and air conditioning, water tanks, doors, monitoring, event recording and other equipment; (2) Collection of sensor information such as bearing temperature, speed measurement, and lateral vibration; (3) Communication network used by passengers...
