The second power data is the power data before the failure. The central processor can analyze the power data before and after the power system failure, know the reason and location of the power system failure, and avoid the failure of the power system. The power data before the failure cannot be obtained, only the power data after the power system failure can be obtained, and the failure of the power system cannot be accurately analyzed. In this embodiment, the power data is the waveform of the power signal. In this embodiment, most of the faults in the power system are short-circuit faults. During the short-circuit fault, the current in the power system will increase, and a traveling wave will be generated at the same time. Or the traveling wave signal triggers the interrupt of the central processing unit, so as to wake up the central processing unit to work when the fault occurs.

It should be noted that, assuming that the normal operating power of the sensor is 5mw, a point is uploaded in 10 minutes in a steady state, and the upload time is 1s. During the fault process, 5 cycles before and after the fault are uploaded, that is, 100ms of data. In the process of capturing the fault without using the fault signal trigger module, it is necessary to collect data in real time and calculate the data, so the power of the sensor is 5mW. If the fault signal trigger module is used to wake up the central processing unit when there is a fault, and upload a point within 15 minutes when there is no fault, it can ensure that the power signal is obtained in a steady state without losing the fault process, according to the annual average number of faults in the network area 2 times For example, 5mW*1/60/10+5mW*1*2/365/24/60/60=8μw, through this calculation, it can be known that the power consumption of the low-power control method of the battery-powered sensor using the fault signal trigger module reduced to 0.16%.
