[0022] Example
[0023] The implementation method and circuit for power failure reporting of the power consumption information collection equipment in this embodiment: In this method, the communication module detects the power supply voltage of the meter and the zero-crossing signal of the grid to determine the power failure state. When the power failure state is detected, the carrier chip will Detect multiple grid zero-crossing signals to judge the power-down state. If no zero-crossing signal is detected multiple times, it is considered to be a power-down state, which increases the accuracy of power-down detection; this circuit includes charging circuit, farad capacitor, boost circuit and power-down The detection and control circuit, the charging circuit is connected to the input voltage VDD; the output of the charging circuit is connected to the farad capacitor; the input of the boost circuit is connected to the farad capacitor; the power failure detection and control circuit is...
