MULTI-BUS HYBRID NETWORKING TRAIN CONTROL AND MANAGEMENT SYSTEM FOR MEDIUM-LOW SPEED MAGLEV TRAINS

摘要

Disclosed in the present invention is a multi-bus hybrid networking train control and management system for medium-low speed maglev trains, comprising two levels of networks and three subsystems. One level of network among the two levels of networks is a redundant backbone network consisting of a multifunction vehicle bus (MVB) and an ECN dual bus, and is mainly used for vehicle level monitoring and control and the management of the whole vehicle control network. ECU communication is preferably used, and the MVB serves as a redundant backup. The other level of network is a device level network consisting of RS-485 and CANopen buses, and is used for device level data communication. The three subsystems comprise a vehicle backup camera subsystem, a wireless uploading subsystem and a multifunction monitoring platform. Compared with the prior art, the present invention reduces seven MVB gateways, one power board and one RIOM chassis. Costs of about 146 thousand RMB are saved per train. As the amount of devices is reduced, train weight is reduced, and energy saving is achieved.
