Abstract
Aiming at the problems of two-way information interaction and real-time and reliable transmission caused by the imperfect electricity information acquisition system, this paper proposes an electricity information acquisition system based on narrowband Internet of things (NB-IoT) technology. The system takes STM32 as the micro-controller, and uploads the data of electricity collector to the telecom cloud platform through BC95 wireless communication mode. The user terminal can connect with the cloud platform to realize the collection of electricity information. This paper presents the detailed hardware and software design method of the system. Compared with the traditional electricity information acquisition system, the system has the functions of low power consumption, simple wiring and remote control, and has good application value.
