摘要
【目的】为优化人居环境,实现人性化、智能化照明,设计出基于单片机和HC-SR501的智能家居照明系统。【方法】系统采用红外线人体检测模块HC-SR501来检测判断是否有人存在,并利用光敏电阻来检测周围环境中的光线强度,检测到的相关数据在经过模数转换芯片ADC0832处理后,输送到主芯片STC89C52中,通过程序判断来实现控制照明。【结果】当检测到有人时,照明系统会自动启动,STC89C52会根据光敏电阻采集到的数据,利用PWM技术对照明灯亮度实现分级控制。此外,还能进行手动和自动模式的切换及通过红外遥控设备来实现照明灯系统的无线控制。【结论】经试验测试,智能照明系统具有较高的人性化、智能化,不仅能给人们的生活带来便利,更符合现代环保节能理念,传感器能稳定采集数据、准确控制照明灯启动及调级,具有较好的应用前景。
[Purposes]In order to optimize the living environment and realize humanized and intelligent lighting,a smart home lighting system based on single chip microcomputer and HC-SR501 is designed.[Methods]The system used infrared human body detection module HC-SR501 to detect and judge whether there was anyone,and used the photosensitive resistance to detect the light intensity in the surrounding environment.The detected relevant data were processed by the analog-to-digital conversion chip ADC0832 and sent to the main chip STC89C52,and the control lighting was realized by program judgment.[Findings]When someone is detected,the lighting system will start automatically.STC89C52 will use PWM technology to realize hierarchical control of the brightness of the lighting lamp according to the data collected by the photosensitive resistance.In addition,it can also switch between manual and automatic modes and realize the wireless control of the lighting system through infrared remote control equipment.[Conclusions]The experimental results show that the intelligent lighting system has high humanization and intelligence.It can not only bring convenience to people's life,but also conform to the concept of modern environmental protection and energy saving.The sensor can collect data stably and control the start-up and adjustment of the lighting lamp accurately,which has a good application prospect.
