摘要
Abstract
Combining ZigBee technology and GPRS mobile communication technology, an LED street lamp monitoring system based on ZigBee-FGPRS is designed. Using two pairs of network models and cluster-chain network topology, the system achieves telemetry and remote control of street lamp through the network and intelligent control. A brightness adaptive energy-saving control algorithm suitable for street lamp illumination is proposed. According to the time periods, ambient brightness and staff movements , the algorithm can change the duty cycle of PWM signal, automatically adjust LED brightess and make full use of the controllability of the LED to realize the best illumination control and energy saving.关键词
