Abstract

The invention relates to a control network and a train. Data processing devices are adopted to construct the control network of the train; two data processing devices are arranged on a head train, one data processing device is arranged on each of other trains, one of the two data processing devices of the head train is a master data processing device, the other data processing devices except the master data processing device are slave data processing devices, and the redundant equipment of the head train is connected with the corresponding slave data processing devices, the redundant equipment of each other vehicle is connected with the corresponding slave data processing device, and each slave data processing device is connected with the master data processing device, so that distributed management of the control network is realized, and the flexibility of security protection deployment can be improved.

Description

technical field [0001] The present application relates to the technical field of rail transit communication, in particular to a control network and a train. Background technique [0002] With the Ethernetization of the train network control system and more and more interconnections with external network systems, the existing "intranet mode + management system" is not enough to prevent malicious attacks, and the information security risk of the train network control system is also increasing. highlight. Once the train network control system is invaded and attacked, the mild case may cause the train to fail to start, and a machine failure accident may occur, and the severe case may cause a train safety accident. Therefore, it is of great significance to carry out information security protection for the train network control system of the Ethernet-controlled train. Contents of the invention [0003] To solve one or more problems of the above-mentioned prior art, embodiments...
