教室照明智能系统设计与实现

摘要

本设计以 AT89 C51为主控制电路，软硬件相结合，通过控制采光模块、继电器模块和热释电人体感应模块来判断室内的光照强度和检测室内是否有人，决定是否开灯。其中，继电器模块实现智能控制电源的通断；采光模块应用光敏电阻和 ADC0832实现对光照强弱的判断及处理；热释电人体感应模块检测教室内是否有人。经实际测试，设计中的各组成部分协同工作以此实现教室照明系统的智能控制和高效用电，达到节电节能经济运行的目的，且系统稳定、安全，具有一定的实用价值。%With AT89C51 as its main control circuit and the combination of software and hardware as its base,this system,through controlling of the lighting module,the relay module,and pyroelectric human-body induction module,aims at deciding whether to turn on the lights after judging the indoor light inten-sity and detecting any intruders.The relay module realizes the intelligent control of the switching of the power;the lighting module uses photosensitive resistance and ADC0832 to judge and deal with the light intensity;and the pyroelectric human-body induction module detects if there is anyone in the classroom. The test results show that:every component in the design can work together to realize the intelligent con-trol and the efficient consumption of power;energy-saving and electricity-saving can be achieved;and the system operates in a stable and safe status.The design has considerable practical value.
