With the continuous improvement of automation levels in uranium mines, the reliability of electrical control systems has become a key factor in ensuring production safety and efficiency. This paper addresses the abnormal failure issues of the frequency converter control system in a uranium mining project in Xinjiang and proposes a PLC-based frequency converter communication control and hardwired backup redundancy control scheme. By comparing and analyzing the technical characteristics of terminal control and communication control, a redundant architecture combining Modbus RTU and terminal control is designed and implemented. Practical application shows that this scheme effectively solves the control failure issues caused by communication interference in the original system. The mean time between failures (MTBF) of the system has increased from 168 h before the transformation to over 2 000 h, and the control response time has been shortened to less than 100 ms. The research content provides an important reference for the design of high-reliability control systems in the uranium mining industry, especially for production scenarios with complex electromagnetic environments and stringent reliability requirements.

随着铀矿开采自动化水平的提升,电气控制系统的可靠性成为保障生产安全与效率的关键因素之一。针对新疆某铀矿项目中变频器控制系统出现的异常失效问题,提出了一种基于PLC的“变频器通讯控制+硬线备用”双控方案。通过分析端子控制与通讯控制的技术特点,设计了Modbus RTU通讯与端子控制相结合的容错架构。该方案有效解决了原系统通讯受干扰导致的控制失效问题,系统平均无故障时间(MTBF)由168 h提升至2000 h,控制响应时间缩短至100 ms。该结果为铀矿行业高可靠性控制系统设计提供了参考,特别适用于电磁环境复杂、可靠性要求苛刻的生产场景。

随着铀矿开采自动化水平的提升,电气控制系统的可靠性成为保障生产安全与效率的关键因素之一。针对新疆某铀矿项目中变频器控制系统出现的异常失效问题,提出了一种基于PLC的“变频器通讯控制+硬线备用”双控方案。通过分析端子控制与通讯控制的技术特点,设计了Modbus RTU通讯与端子控制相结合的容错架构。该方案有效解决了原系统通讯受干扰导致的控制失效问题,系统平均无故障时间(MTBF)由168 h提升至2000 h,控制响应时间缩短至100 ms。该结果为铀矿行业高可靠性控制系统设计提供了参考,特别适用于电磁环境复杂、可靠性要求苛刻的生产场景。

With the continuous improvement of automation levels in uranium mines, the reliability of electrical control systems has become a key factor in ensuring production safety and efficiency. This paper addresses the abnormal failure issues of the frequency converter control system in a uranium mining project in Xinjiang and proposes a PLC-based frequency converter communication control and hardwired backup redundancy control scheme. By comparing and analyzing the technical characteristics of terminal control and communication control, a redundant architecture combining Modbus RTU and terminal control is designed and implemented. Practical application shows that this scheme effectively solves the control failure issues caused by communication interference in the original system. The mean time between failures (MTBF) of the system has increased from 168 h before the transformation to over 2 000 h, and the control response time has been shortened to less than 100 ms. The research content provides an important reference for the design of high-reliability control systems in the uranium mining industry, especially for production scenarios with complex electromagnetic environments and stringent reliability requirements.
