智能廊灯控制系统

Control System of Intelligent Porch Lamp

以智能和绿色环保为导向设计系统;系统使用集成PWM、AD转换功能的STC12系列单片机和无线传感器实现廊灯的智能化控制;应用PWM技术实现LED照明光源大范围调光的控制和驱动;电源采用太阳能和市电结合。白天系统进入掉电模式,天黑(环境亮度不够)系统自动启动;人走近时灯光自动点亮,人离开后30秒自动灭;系统启动5小时后自动进入睡眠模式;系统具有防盗功能,夜间灯光不定时点亮,模拟有人在家欺骗盗贼,同时无线门磁实现报警防盗功能;当主灯坏时,廊灯可作为后备灯源;正常模式、睡眠模式、后备灯源模式各灯的亮度均可自由调节。

With intelligence and green environmental protection as the guide to design system,system uses STC12 series microcontroller which with PWM integrated function of AD transform,and wireless sensor lamp of intelligent to control realization corridor,application of PWM technology used for lighting source of LED light control and drive.Power is the combination of solar energy and utility.Function： system into the lose power mode in the daytime.At night,or when the brightness of the environment,system will automatically activated.When human approached,light will automatically light,when human left,it will shut down automatically after 30 seconds.When the system has worked five hours,will enter sleep patterns.Besides,system has the function of security.At night,the light will be lit immediately.Simulation anyone is at home to deceive the thief,at the same time,the wireless magnetic door will enter alarm security model.When the light cannot work,System can provide back-up light source.Whether in normal mode,sleep patterns or back-up light source model,the lamp brightness can be adjusted freely.
