摘要
为实现路灯按需照明和实时监控管理的使用需求,设计以CC2530为控制器,采用ZigBee和GPRS通信的路灯无线监控系统.各路灯节点可工作于环境光照模式、设定时间模式或上位机指令模式.LED调光电路采用PWM调光方式,通过CC2530芯片产生低频PWM调光信号,采用调光芯片HV9910对路灯节点进行调光控制.实际装置的调试与测试结果表明,所设计的装置能实时监测路灯故障信息,路灯亮度可调节,可实现单灯开关控制,能够实现对城市路灯工作状态的集中监控.
Street lamps monitoring system is designed that the chip CC2530 is used as controller by using ZigBee and GPRS Communications technology. Each street lamp node can work in one of three modes, environment illumination mode, designated time mode or the PC instruction mode. PWM method is adopted in LED dimming circuit, that the low frequency PWM dimming signal is created through CC2530 chip and the light of street lamp node is adjusted by use of HV9910 chip. The debugging and testing results show that the actual device can monitor the streetlights fault and adjust street lamp brightness, and realize single lamp switch controlling and centralized monitoring for the city street lamps.
