Embodiment Construction

[0028] The redundant control method of the locomotive communication network will be further described below in conjunction with the accompanying drawings.

[0029] 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 ...

Abstract

The invention discloses a redundancy control method for a locomotive communication network. A locomotive control and monitoring system receives locomotive real-time information sent by electrical equipment of a locomotive; communication tasks between the electrical equipment mainly comprise a main task and an auxiliary task; a vehicle level network communication mode includes MVB communication and Ethernet communication, and a train level network communication mode is WTB communication; and communication network redundancy comprises double-network redundancy and WTB network redundancy. The redundancy control method has the advantages that first-choice communication networks and communication periods of different sets of electrical equipment are set according to tasks executed by the electrical equipment; meanwhile, a loop is formed by an Ethernet switchboard; different sets of equipment respectively communicate with different Ethernet switchboards to realize redundancy of the Ethernet, provide a definition of the double-network redundancy and a definition of the WTB network redundancy; the redundancy efficiency of the locomotive is improved; and furthermore, the demand of the locomotive for two communication periods is met.

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...
