学 院 本科毕业论文（设计)基于单片机的智能声光控开关李波XXXXX专 业 名 称 电气工程及其自动化 申请学士学位所属学科 工科 指导老师姓名、职称 XXXXXXXX 2024 年 6 月 8 日摘 要声光控开关的原理是只有在天黑以后，当有人走过楼梯通道,发出脚步声或其它声音时，楼道灯会自动点亮，提供照明,当人们进入家门或走出公寓，楼道灯延时几分钟后会自动熄灭.在白天,即使有声音,楼道灯也不会亮，可以达到节能的目的。 本文以 LGS 公司生产的 GMS97C2051 单片机为核心，讨论声光控开关的设计，采纳串行 A/D 对声音信号的采集，可以通过软件来调节对声音的灵敏度。单片机软件实施对光度的推断，使开关在白天时即使有声音也不工作。文章应用了过零启动技术，开关工作在频繁的开关状态时不易损坏可控硅，延长了声控开关的使用寿命。文章中还加入了看门狗电路，在工作中可以起到抗干扰的作用，大大加强了开关的可靠性.关键词：声光控，智能，节能,可靠性.ABSTRACTThe principle of acoustic optical switch is only after dark, when someone pass stair channel, issued， or other sounds of footsteps will provide automatic lit corridor ， lighting, when people enter the house or apartment corridor lights out several minutes automatically delay extinguished. During the day， even a voice, corridor lights also will not light， can achieve the purpose of saving energy. In this paper GMS97C2051 LGS company production ， the single-chip microcomputer is thedesign of acoustic light—activated switch, the serial A/D for sound signal collection, by software to adjust the sensitivity to sound 。 Single-chip microcomputer software implementation on photometric judgment to make the switch in the daytime， even though there is voice doesn’t work. Article applied zero start up technology ， switch work in frequent switch to thyyistoy andextendedofsound—controlled。 Article also joined watch-dog circuit， in the work plays a role of anti—interference, the reliability of switches is greatly enhan...
