光照控制自动照明系统的设计

摘要

为了解决公共建筑的用电浪费问题，设计了一种自动节能系统。此系统主要是避免白天或无人时仍然开灯，以及人走之后电器设备仍在使用的情况，因此可以根据可见光强度和是否有人控制照明电源的通断。这个系统与以往不同之处在于系统中加入了报警和手动开关。

系统主要用在室内，解决室内的用电浪费问题。它以单片机80c51作为主要控制器，用光敏电阻检测光照强度，用红外传感器检测人体是否存在。在运行过程把光亮度情况作为灯亮的首要条件，有人存在作为第二条件，这样就可以实现最大程度上的节能。考虑到人性化因素系统加入手动开关和报警电路，用来通断总电源和提醒人未被红外传感器检测到。使电灯在白天（阴天除外）不亮，晚上有人来时亮灯，人走后延时一段时间自动熄灭，从而达到节能的目的。系统电路简单，控制灵活，适用于多种公用建筑供电系统的安全、节能管理。

Design of Lighting control automatic lighting system

Abstract

In order to solve the electrical safety and electricity energy waste problem in public buildings on campus,an automatic energy-saving system was designed.This system mainly is to avoid daytime or no person still open lamp, and people will leave after electrical equipment still in using. So according to visible light intensity and whether someone control lighting power hige. This system differs from previous joined the alarm and in the system manual switch.

System is mainly used in indoor to solve indoor waste electricity issue. System for main controller is 80c51 SCM . Using photoconductive resistance detects light intensity. Using infrared sensors detect anyone. The brightness in operation process for the primary condition, some light existence as a second term, which can achieve maximum degree of energy saving. Considering human factors, the manual switch was added in the systems, Used to hige total power and remind people were not detected infrared sensors. Making the light during the day does not shine. Cloudy day and night someone comes light on. After they leave delay for a period of time, so as to achieve automatic extinguish the purpose of energy-saving. The system was simple and flexible control, energymanagement for a variety of public building power supply systems.

Key words:single chipprocessor, energy -saving, heat release infrared sensor pyroelectric infrared sensor, power control
