CAN现场总线构成的铁路调车场控制网络

CAN Field-bus Controlled System of Railroad Marshalling Yard

由CAN现场总线构成的铁路调车场控制网络与微机可控顶调速控制技术相结合,实现信息交换和资源共享,从而使微机可控顶调速控制技术从开环控制升级为闭环控制,对提升整个控制系统的性能起到积极作用。

Computer nerwork is a new technical field combined with computer technology and technical field and the information can be shared in the network. The computer network applied in the railroad marshalling yard has its own characteristic which is different from the others. It is a kind of the bus - field used in the bottom of the production as the bus topology network. This bus links the central control unit, spot control, and all the controlled nodes directly or serially to form anetwork. Inthe grotty environment, CAN field-bus can be installed for its good anti - interfrernce feature and high -power of real time control.
