摘　　要：针对棒位检测对通信系统的实时性、准确性、安全性、可靠性和有效性要求极高,设计了一种双通讯冗余的棒位检测仪。该系统由CPU控制单元、通讯电路单元、状态监控单元、状态指示单元等模块组成,每一个单元均是采用双冗余设计。两套系统相互发送心跳信号,检测对方工作状态和传输数据;一旦一套系统出现故障,另一套系统立刻替代工作,检查故障,并将故障反馈给上位机。性能验证试验结果表明,该冗余通讯系统工作稳定,测量准确,符合核反应堆控制棒棒位检测要求。According to the rod position detection of the communication system real-time , accuracy, security, reliability and validity highly requirements, a dual communication redundancy of rod position detector is designed. Which are composed of CPU control unit, communication circuit unit, condition monitoring unit, status indication unit etc, each unit is designed with double redundancy. Two systems send each other the heart signals, test each other working status and data transmission; Once a system failure, another system replace immediately ,check the fault and feedback the failure to PC.The performance verification experimental results show that the redundant communication system working stability, measurement accuracy, conform to the requirements of the nuclear reactor control stick a detection.
