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.
In order to realize the street lighting on-demand lighting and real-time monitoring and management needs of the use of the design, CC2530 controller, using ZigBee and GPRS communication street lamp wireless monitoring system.Each street lamp node can work in ambient light mode, set the time mode or host computer command Mode.LED dimming circuit using PWM dimming mode, through the CC2530 chip to generate low-frequency PWM dimming signal, the dimming chip HV9910 on the street lamp node dimming control.The actual device debugging and test results show that the device designed to real-time Monitoring street lamp fault information, street lamp brightness can be adjusted to achieve a single light switch control, to achieve the status of urban street lamps centralized monitoring.
