Research on Remote Meter Reading Scheme and IoT Smart Energy Meter Based on NB-IoT Technology

The energy meter supporting the NB-IoT standard protocol is designed to be connected to the NB-IoT network through the protocol conversion of the remote communication module itself, and directly connected to the existing centralized meter reading automation system. The acquisition terminal device is omitted, and direct communication between the main station and the energy meter is realized. The end-to-end standardized protocol reduces the complexity of the centralized meter reading platform architecture and improves the system's openness and scalability. It realizes end-to-end visual management and real-time monitoring, improving the safety, reliability and fault resistance of power collection. The overall scheme can reduce the large amount of human and material costs of system operation and maintenance.
