The Intelligent Street Light Control System for Preventing Heavy Fog of Expressway Based on ZigBee

In the severe weather such as heavy fog, there are car serial rear-end collision accidents in the expressway sometimes. In order to avoid such accidents, the expressway is often closed. The reason for the rear-end collision is that the drivers’ vision is limited in heavy fog and the vehicle ahead is not clear. There are many problems in the traditional street lighting system, such as the inability to intelligently control street lights according to the weather conditions, so it has been unable to meet the lighting needs of the highway. For this reason, this paper proposes a design scheme of intelligent street lamp control system for preventing heavy fog of Expressway Based on ZigBee technology. The system mainly uses CC2530 as the core device to collect the temperature and humidity on site in real time and automatically control the LED street lamp switch for lighting according to the collected data. The experimental results show that the system is easy to operate, responsive, energy-saving and emissions reducing, and can meet the needs of intelligent lighting in the expressway.
