How is the remote meter reading function of the three-phase intelligent energy meter realized?
The remote meter reading function of the three-phase intelligent energy meter is mainly realized through the process of "data collection by metering chip → data transmission by communication module → reception and processing by backend system", as follows:
Data acquisition layer: The electric meter has a built-in high-precision metering chip that collects electrical parameters such as voltage, current, and power in real time. These parameters are calculated and converted into electricity consumption data, which are stored in the local memory.
Communication and transmission layer: Through built-in communication modules (such as RS485, NB-IoT, 4G, LoRa, etc.), the locally stored electricity data is sent to the concentrator or cloud platform at a set frequency (such as every 15 minutes or every hour) or on demand. Among them, wireless communication (NB-IoT, 4G) does not require wiring and is suitable for decentralized scenarios; wired communication (RS485) has high stability and is often used in densely populated electricity consumption areas.
Data processing layer: Backend systems (such as power marketing systems, energy management platforms) receive the transmitted data, perform verification, parsing, storage and statistics, and generate electricity reports, trend curves, etc., realizing remote automatic meter reading, data query and abnormal monitoring.
The entire process requires no manual intervention, which improves the efficiency of meter reading and data accuracy, and is one of the core functions of the smart grid electricity information collection system.
