Reconnection gateway and passenger information system containing reconnection gateway

Abstract

The invention relates to a reconnection gateway and a passenger information system containing the reconnection gateway. The reconnection port of the vehicle reconnection server and the reconnection port of the main vehicle reconnection gateway are in a mirror image relationship; the passenger information system includes a reconnection gateway and an Ethernet switch, and at least one Ethernet switch is set in each carriage; The network gateway is connected to the Ethernet switch through the Ethernet bus, and the Ethernet switch is connected to all devices with network communication functions in the passenger information system through the Ethernet bus. The present invention can convert the IP address of the network when the train network is reconnected, and solves the problem that IP address conflicts will occur in the passenger information system when the network is reconnected, resulting in the failure of the communication function of the equipment with IP address conflicts in the local area network, and has high reliability. , simple wiring, easy maintenance, occupying vehicle space, and less weight.

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 ...
