Abstract
Aiming at the control methods of the streetlights, as well as the problems of high energy consumption caused by the continuous lighting of streetlights despite of few pedestrians at night in the park, this paper proposes a smart streetlight system for parks based on NB-IoT (Narrow Band Internet of things) technology, which uses STM32L431RCT6 single-chip microcomputer as the main control chip, collects the ambient illuminance information through a light sensor, and transmits it back to the HUAWEI CLOUD platform through the NB-IoT communication module, so as to realize automatic remote control of streetlights on the terminal side. When the Streetlight is in the lighting state, the brightness of the street lamp is set to 50%, and if the infrared sensor detects human movement, the brightness of the Streetlight is increased; and the brightness will be reduced after the human moves away. Experimental data show that the system can realize the automatic remote control of a single streetlight according to the ambient illuminance, and automatically adjust the lighting brightness of the streetlight at night by detecting human movement, so as to effectively save electricity and reduce energy consumption.
