The invention discloses a dual-core operation state mutual inspection type electric energy meter, which comprises a metering core and a management core. The metering core and the management core are independently operated through respective clocks. The metering core is provided with a metering MCU, a metering reset circuit and a metering UART circuit. The management core is provided with a management MCU, a management reset circuit and a management UART circuit. The metering UART circuit is in communication connection with the management UART circuit. The metering core and the management coreare mutually detected. When a fault occurs, the metering core and the management core are reset through respective reset circuits. According to the invention, the metering core and the management coreare mutually detected, so that a short-time fault can be rapidly and automatically recovered as long as the device is not damaged.
