中文摘要：
为了满足逆变电源多模块监控的实时性、可扩展性、灵活性、可靠性等需求，对现场总线进行了研究和分析，系统采用CAN现场总线作为通信传输方式组建了监控网络，对带DSP控制器的逆变电源模块进行监控。在此基础上详细描述了操作站一侧监控方案的设计，重点介绍了CAN总线应用层协议的具体制定以及系统通信软件的设计和实现，实现了操作站与控制器的通信，完成了对逆变电源模块的监控功能。
英文摘要：
In order to meet the real-time, expansibility, flexibility and reliability requirements of the inverter power supply mutil-module monitoring, CAN is used as system communication mode for constructing monitoring network to monitor inverter power supply module with DSP controller. On these bases, monitoring scheme at operation site is described, then protocol of the application layer and communication software design and realization are mainly introduced. Communication between operation site and controller, monitoring function of inverter power supply are thus realized.
