Problems solved by technology

[0004] Among them, using a single wireless communication technology to deploy A and B redundant dual networks can effectively improve the reliability of the communication system, but some reliability problems still exist
"Common cause failure" is the main root cause of redundant system failure. Because the A and B redundant dual networks in the rail transit communication system use the same wireless communication technology, it is very easy to cause system downtime due to the same reason.

Abstract

The invention relates to a rail transit communication system and method, computer equipment and a storage medium. The communication system comprises a first communication system, a second communication system, a gateway and a vehicle-mounted controller, wherein the vehicle-mounted controller comprises a first vehicle-mounted controller and a second vehicle-mounted controller, and the gateway comprises a first gateway and a second gateway; the first vehicle-mounted controller sends the data packet containing the destination IP to a first gateway; the first gateway captures the data packet fromthe network card according to a rule, analyzes a destination IP, and sends the data packet to the second gateway through the first communication system and the second communication system according tothe destination IP; and the second gateway sends the data packet to the second vehicle-mounted controller, so that the problem of common cause failure is avoided, and the reliability of the system isimproved.

Description

technical field [0001] The present application relates to the technical field of rail transit, in particular to a rail transit communication system, method, computer equipment and storage medium. Background technique [0002] All countries in the world are vigorously promoting the development of rail transit unmanned train control systems. Among them, the train control system based on communication is the main direction of train control system development. According to the definition of IEEE1474, a communication-based train control system is a "continuous, automatic train control system. Using high-precision train positioning outside the track circuit; continuous, high-capacity, two-way train-ground data communication; Train protection functions with on-train and wayside data processing capabilities, and optional automatic train operation and automatic train monitoring functions". Compared with the manual driving mode, the automatic train driving mode can effectively reduc...
