摘　　要：控制器局域网络(CAN)总线在工业控制和工业自动化等领域有广泛的应用。成功研制了基于CAN总线的高可靠测控单元:分析了CAN总线的特点及其在高可靠部件中应用的可行性和优越性;基于先进的RISC机器(ARM)单片机和CAN总线,设计了高可靠测控单元相应的软硬件,实现了高可靠部件状态控制与测试功能。实验结果表明,该测控单元具有实时性和可靠性,很好地完成了高可靠部件测控任务。Control Area Network(CAN) bus is widely used in industry control and industry automation. A high-credibility supervision unit is successfully developed based on CAN bus. First, characteristics, feasibility and advantages of CAN bus in modules with high credibility are analyzed. Then, software and hardware of high-credibility supervision unit are designed based on Advanced RISC Machines(ARM) Single Chip Microcomputer(SCM) and CAN bus, and the state control and test to high-credibility module is realized. Experiment results indicate that the proposed unit achieves real time capability and reliability, and its supervision mission to high-credibility module is well accomplished.
