摘要
为了满足模块式电源对可靠性的严格要求,提出了具有容错控制的双机热备份机制。研究分析了双机热备份的设计需求,完成了基于CAN总线通信的模块式电源监控系统双机热备份的设计。本文在CAN总线通信协议设计的基础上,深入讨论了在双机热备份实现过程中监控系统的状态诊断方法、实时数据同步策略以及切换控制,并给出了具体的设计和实现。
To satisfy the strict requirement on reliability for module power, dual hot standby mechanism with fault- tolerant control is proposed in this paper. Design requirement of dual hot standby is research and analyzed, then the design of dual hot standby with monitoring system of module power supply is completed based on CAN bus communication. State diagnosis, real time synchronization strategies and switch control in the realization process of the dual hot standby with monitoring system are discussed further based on CAN bus communication protocol design basis, and gives design and implementation specifically.
