模拟路灯控制系统设计 摘要 本设计是一种采用新一代超强抗干扰/强抗静电/高速/低功耗单片STM32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。采用节能环保的LED灯作为光源，采用科学有效的检测与控制技术，实现了光电控制、时间控制、交通情况检测、故障自动检测与报警等功能，节省了人力和电力资源，降低了系统运行成本，性价比较高。通过光敏电阻模块检测LED故障，ULN2803芯片控制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。 关键字：STM32-cortex-m3； Abstract This design is a new generation of powerful anti-interference / strong antistatic / high / low power single chip STM32 as the data processing and control of street lamp intelligent lighting system. The single chip microcomputer to achieve the bright lights out of control, alarm, and the timing function. The energy saving and environmental protection of the LED lamp as the light source, the use of scientific and effective detection and control technology, realize the photoelectric control, time control, traffic condition detection, automatic fault detection and alarm functions, saving manpower and electric power resources, reducing the operation cost of the system, price is comparatively high. Photosensitive resistance through fault detection module LED, ULN2803 chip control LED lamp status, use of photosensitive resistance theory and infrared tube characteristics to realize automatic adjustment of road lamp switch state.
