CAN Bus Research In Computer Based Supervision System

This paper is mainly about the research and development of the computer based supervision system used in railway signaling field. The aim research of this paper is to guarantee the function of communication system which is constructed by the reliable, high-speed and easy configurable CAN bus network between the host device and the data collected device performinging well under the complicated condition in railway stations. A full-scale dual-CAN bus design is used as communication strategy, meanwhile there are kinds of design both in software and hardware development to enhance the reliability, whose thoughtway and key technic are described in detail. In the article, a specific project is designed both in software and hardware. After the process of experiment and test, the system performs functionally. Further research in the aspects including real-time ability of communication, capability of communication, baud rate and network load rate is done in this paper. Kinds of method to test the performence of CAN bus which could be influenced by the factors mentioned above are designed and implemented. 21 figures, 30 tables, 30 references.
