摘　　要：文中设计完成了一款基于51单片机的灯光控制器。当环境光线昏暗时,达到"人来灯开,人走灯灭"的效果。设计中利用光敏电阻GL5528采集环境光照强度,经过集成电压比较器LM393处理,人体红外线集成感应器HC-SR501采集人体活动信息,三极管功率放大,将环境光线和人体活动信息采集输入进单片机系统。单片机经过程序运行分析判断,输出控制继电器线圈,顺利实现灯光智能控制。程序软件编程部分紧凑高效,顺利通过Proteus仿真运行调试,结果证明本设计功能实现正常,能够达到预期控制功能。This paper designed a light controller based on 51 single chip microcontroller.When the light of the environment is dim,the effect of"When a man comes,the light is turned on,when a man leaves,the light goes out"is achieved.In the design,we used the photosensitive resistor GL5528 to collect the ambient light intensity,send this signal to the integrated voltage comparator LM393.The human infrared integrated sensor HC-SR 501 is used to collect human activity signal.Power transistors are adopted to amplifier the ambient light intensity and the human infrared signals,then the two signals are send into the single-chip microcomputer.After run a related program,the single chip microcomputer outputs a level signal to control a relay coil,correctly realize the function of light control.Software program is compact and efficient,it can be correctly executed and debugged through Proteus simulation.The result proves that the design function is normal and can achieve the expected control function.
