description The invention provides an intelligent electric meter, which comprises an AC signal sampling circuit, an electric energy metering circuit, an MCU master control data management unit, a temperature acquisition circuit, an RS485 communication circuit and a relay protection circuit, wherein the AC signal sampling circuit is sequentially connected with the electric energy metering circuit and the MCU master control data management unit; the MCU master control data management unit is connected with the temperature acquisition circuit and the relay protection circuit; and the MCU master control datamanagement unit is mutually connected with the RS485 communication circuit. The intelligent electric meter can be applied to single-phase power and three-phase power, and can also simultaneously monitor the voltage, current, power, power consumption and cable temperature of three paths of single-phase electrical equipment, thereby greatly improving the number of monitored paths. The intelligent electric meter can further
