Research and Design of Solar LED Lighting Intelligent Control System Based on the Internet of Things

Due to the low efficiency, short lifespan and fluctuation performance of current solar lighting system, this paper introduces a new ZigBee solar lighting controlling system with remote wireless networking designed by us. By way of collecting data via relevant sensor and passes the data to monitoring center by ZigBee and GPRS wireless, showing the collected data synchronously, it realizes the wireless remote monitoring and intelligent controlling. The controlling system includes upper computer, integrated controller and solar LED lighting controller. Solar LED lighting controller includes charging controlling module, data collection module, LED lighting driving module, wireless communication module and power management module. The controlling system monitors the charging state of storage battery synchronously and switches the charging model correctly in order to enhance the charging efficiency. Also, it tracks the maximum power point of solar panel by perturbation and observation control; it adopts the PWM to adjust LED constant current output so as to reach the energy saving effect. Combining the networking strategy of ZigBee, GPRS and Internet, it realizes the solar street light self build network and remote intelligent monitor.
