摘要
介绍了一种LED智能照明控制系统的设计,给出了系统的软硬件设计和控制流程。该系统采用STC12C5A60S2作为主控器,利用热释红外传感器检测人体辐射的微量红外线,光敏电阻检测环境亮度,采用DS18B20检测LED的温度,LED驱动采用PWM调光技术。
A set of LED lighting intelligent control system was introduced. The design of hardware and software are given. Using STC12CSA60S2 as the master of the system. The pyroelectric infrared sensor was used to detect trace red infrared of humam radiation. Ambient brightness was detected with photoresistor. The LED temperature was detected with DS18B20. LED driver with PWM dimming technology.
