The three-phase four-wire electronic prepaid energy meter consists of five main functional blocks: one is the energy metering part; two is the microprocessor control part; three is the CPU card part; four is the 485 communication part, and five is the power supply circuit. The energy metering part uses a dedicated large-scale integrated circuit chip, which can generate a pulse sequence indicating the amount of electricity used, which is sent to the microprocessor for energy metering and stored in the CPU card; the microprocessor transmits data with the energy card (IC card) through the power card interface to achieve various control functions; the 485 communication part realizes the setting of the meter function parameters and the reading and writing of the data in the meter under the control of the microprocessor; the power supply adopts a three-phase power supply circuit, and the energy meter can still work normally in the phase-loss state.
