LoRaWAN Electric Meter

HKT single-phase fee-controlled smart electric energy meter is a new generation of electric energy metering product developed and produced by our company according to the relevant technical specifications of smart electric meters of State Grid Corporation. This product adopts application-specific large-scale integrated circuit and SMT production process, and has the functions of electric energy metering, data processing, real-time monitoring, automatic control, information interaction and so on.

 Working Principle

When the electric energy meter works, the voltage and current are sampled by the sampling circuit respectively, then sent to the electric energy metering application specific integrated circuit for processing, and converted into digital signals and sent to the microprocessor for calculation. The microprocessor in the figure is used for time-sharing charging and processing various input and output data. Time-sharing active electric energy metering is completed by collecting electric energy pulses of the electric energy metering application specific integrated circuit. Various data are displayed as required, communicated and transmitted through carrier wave, infrared or 485 interface, and various data are recorded and stored.
