(word完整版)基于单片机的教室灯光控制系统的设计.doc

机的教室灯光控制系统。该系统以 AT89S51 单片机作为控制模块的核心部件,采用热释红外人体

传感器检测人体的存在，采用光敏三极管构成的电路检测环境光的强度;根据教室合理开灯的条

件，通过对人体存在信号和环境光信号的识别与判断，完成对教室灯光的智能控制,避免了教室

用电的大量浪费。系统还具有报警功能；同时还采用了软/硬件的“看门狗”等抗干扰措施。该

系统可以满足各类院校对教室灯光控制的要求，很大程度的达到节能目的。

lighting。 The navar according to the resonable conditions of turning on classroom light

and the identification of signal about environmental lighting and existing of

human body, achieved the intelligent control of classroom lighting . At last， it avoid

the waste of electricity 。 It also had alarming function, at the same time

anti-interference measures such as the software / hardware ”watchdog" was adopt.

The system can meet institution requirements for classroom lighting control， largely

achieved the purpose of energy saving.
