采用新一代超强抗干扰/强抗静电/高速/低功耗单片STC11F32XE为数据处理和控制的路灯照明智能系统。该单片机实现了对路灯的亮灭控制、报警、还有定时功能。通过A/D转换TLV2543检测LED故障，D/A转换芯片TLC5620控制LED灯状态，利用光敏电阻原理和红外对管特性实现自动调节路灯开关状态。同时成功设计了恒流驱动电源电路，使LED正常稳定的工作，并完成了自动调节路灯驱动电源输出功率，基本上解决了LED灯不能工作在稳定电流的问题。-Interference by a new generation of super/strong antistatic/high speed/low power single STC11F32XE for data processing and control of street lighting intelligent systems. The MCU of the bright lights off control, alarm, there is timing. Through the A/D conversion TLV2543 LED fault detection, D/A converter chip TLC5620 control LED light status, use of resistance theory and the infrared photosensitive properties of the tube lamp switch automatically adjust the state. Also successfully designed constant current drive power supply circuit, so that the normal steady LED 的 exercise and complete the Zidong adjust lamp drive power Shuchu power basically solved LED 灯 not work in the stable current problems.
