In some implementations, the smart switch socket 20 is automatically powered off when the judgment result of the processing module 51 is abnormal. Here, the processing module 51 can be disposed in the power line monitoring unit 10 , the smart switch socket 20 , the disaster prevention monitoring host 80 or the cloud server 90 as described above, and can be notified through a warning message as described above, namely It can effectively manage and control the connected electrical equipment of the smart switch socket 20 .

Therefore, the power line monitoring unit 10 and the smart switch socket 20 use the voltage reading value measured by the high-precision 16-bit ADC, and use the reading value monitored at both ends to calculate the difference voltage value, and then determine the regression loss analysis of the power line L, if any In the event of an abnormality, the connected electrical equipment (such as a dehumidifier) can be automatically powered off.

In addition, the safety factor value is proportional to the difference between the measured value and the wiring resistance, and is inversely proportional to the wiring resistance. Preferably, the safety factor value is C, the measurement value is Rm, and the wiring resistance is Rr, therefore: C=(Rm-Rr)÷Rr.

Possibly, the risk of fire on the power line will increase for a long time. Therefore, the processing module 51 determines that the power line L is in a short-circuit state when the safety factor is negative.

Therefore, the standard voltage obtained by the power line monitoring module 11 connecting the secondary side of the switchboard is Vm, the actual voltage measured by the switch socket monitoring module 21 is Vs, and the wiring resistance based on the known wiring length and wiring diameter is R , the voltage of the two terminals is added to the measured current value, and the Rm (measured value) is obtained through calculation. Based on the analysis of big data, the preset safety factor value C is set, and then according to different safety factor values Cn, Send different signals to the disaster prevention monitoring host 80 and send them to the cloud server 90 for big data analysis and supervision.
