Embodiment Construction
[0024] The redundant control method of the locomotive communication network will be further described below in conjunction with the accompanying drawings.
[0025] In this locomotive communication network redundancy control method, the locomotive control and monitoring system TCMS receives the real-time locomotive information sent by the electrical equipment of the locomotive, and the communication tasks between the electrical equipment are divided into main tasks and auxiliary tasks, and the vehicle-level network communication mode is MVB communication and Ethernet communication, train-level network communication mode is WTB communication. The vehicle-level network communication redundancy includes dual-network redundancy and input-output module redundancy, and the dual-network redundancy includes MVB redundancy and Ethernet redundancy. The train-level network communication redundancy includes WTB network redundancy. The MVB communication includes an MVB communication A bus ...

The invention discloses a locomotive communication network redundancy control method. The locomotive control and monitoring system receives real-time locomotive information sent by the electrical equipment of the locomotive. The communication tasks between the electrical equipment are divided into main tasks and auxiliary tasks. The vehicle-level network communication mode is as follows: MVB communication and Ethernet communication, train level network communication mode is WTB communication, communication network redundancy includes dual network redundancy and WTB network redundancy. The invention has the advantages of setting the preferred communication network and communication cycle of different electrical equipment according to the tasks performed by the electrical equipment, and at the same time the Ethernet switch forms a loop, and different equipment communicates with different Ethernet switches respectively, thereby realizing the redundancy of the Ethernet , put forward the definition of dual network redundancy, and put forward the definition of WTB network redundancy. The redundancy efficiency of the locomotive is improved, and the requirements of two communication cycles of the locomotive are met at the same time.
Description
technical field [0001] The invention relates to a redundant control method for a locomotive, in particular to a redundant control method for a locomotive communication network and belongs to the field of locomotives. Background technique [0002] The locomotive control and monitoring system controls the operation of the whole locomotive, because the locomotive control and monitoring system receives real-time locomotive information sent by all the electrical equipment of the locomotive, and at the same time the locomotive control and monitoring system sends control commands to the corresponding electrical equipment of the locomotive in real time, so locomotive control and monitoring The system must communicate with all electrical equipment of the locomotive through the network, and the communication network must be redundant and real-time. [0003] At present, there are mainly several redundancy control methods for communication networks. But there are certain shortcomings t...
