| Abstract: |
| In response to the problems such as communication interruption, instability, and abnormal node device functions in the sensing layer of the KJ90-NX security monitoring system, maintenance personnel cannot quickly locate and deal with low efficiency problems, and design a fault diagnosis device. 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. |
