Reconnection gateway and passenger information system comprising same

Abstract

The invention relates to a reconnection gateway and a passenger information system comprising the same. According to the reconnection gateway, the IP address of a service car reconnection server and the IP address of a service car reconnection gateway are configured into a mirror image relation, and a reconnection port of the service car reconnection server and a reconnection port of the service car reconnection gateway are configured into a mirror image relation. The passenger information system comprises the reconnection gateway and Ethernet switches, and one or more Ethernet switches are arranged in each compartment; the reconnection gateway is connected with the Ethernet switches through an Ethernet bus, and the Ethernet switches are connected with all equipment with a network communication function in the passenger information system through the Ethernet bus. During train network reconnection, the network IP addresses can be switched, the problem that during network reconnection, IP address conflict may occur to an existing passenger information system, and consequently the communication function of the equipment in the IP address conflict within a local area network loses efficacy is solved, reliability is high, wiring is simple, maintenance is easy, and less train space and weight are occupied.

Description

technical field [0001] The invention belongs to the technical field of railway train passenger information, and relates to the passenger information technology of high-speed EMUs. Specifically, it relates to a reconnection gateway and a passenger information system containing the reconnection gateway, which are mainly used in high-speed EMUs. Background technique [0002] With the development of modern rail transit technology, the intelligence, automation and high-end aspects of rail trains have all been improved. On the basis of the greatly improved safety, comfort and speed of my country's standard EMUs, the requirements for the reliability and maintainability of trains are also getting higher and higher. It is particularly important to develop and design a new type of passenger information system. [0003] When the bicycle network is not reconnected, all equipment in the passenger information system can work normally. In the state of two-vehicle or multi-vehicle network ...
