煤矿安全监控系统感知层故障诊断装置的设计

Design of fault diagnosis device for perception layer of safety monitoring system

针对当KJ90-NX安全监控系统感知层出现通信中断、不稳定、节点设备功能异常等常见故障时,维护人员无法快速定位、处理效率低的问题,设计一种故障诊断装置。该装置通过集成丰富的检测电路,移植上位机、分站、传感器等节点设备协议,结合正确的测试方法和判据,实现故障准确定位。实际应用表明,该设备具有准确率高、操作简单、携带方便等特点。

In response to the problem that maintenance personnel cannot quickly locate and deal with low efficiency when communication interruption,instability,and abnormal node device functions occur in the sensing layer of the KJ90-NX security monitoring system,a fault diagnosis device is designed.The device integrates rich detection circuits,transplants node device protocols such as host computers,substations,sensors,etc.,and combines accurate test methods and criteria to achieve accurate fault location.The practical application shows that the device has the characteristics of high accuracy,simple operation,and convenient carrying.
