Zero-power-consumption radio frequency meter reading electric energy meter

The utility model provides a zero-power-consumption radio frequency meter reading electric energy meter which includes a main controller, an electric-energy metering module, a communication module and a storage module. The main controller includes a CPU and a minimum system circuit thereof. A resistor R1 and a C1 are serially connected so that a reset circuit is formed. One end of the resistor R1 is connected with a +5V power supply and a VCC port of the CPU, and the other end of the resistor R1 is connected with the capacitor C1 and a RESET port of the CPU. One end of the capacitor C1 is connected with the resistor R1 and the RESET port of the CPU, and the other end is grounded and connected with a VSS port of the CPU. In the zero-power-consumption radio frequency meter reading electric energy meter, data in the electric energy meter can be read in a wireless method in different environments such as normal work, fault, damage, normal power supply and power supply failure and the like of the electric energy meter.
