常州刘国钧高等职业技术学校毕业论文论文名称 基于单片机的教室灯光控制系统的设计 系 部 机电工程系 专 业 电气自动化 班 级 1 164 姓 名 周新成 学 号 1 16419 2025 年 4 月 1 日基于单片机的教室灯光控制系统的设计摘要：本文针对高校教室照明的特点和应用需求,提出了一种基于单片机的照明控制系统。AT89S51 单片机作为控制模块的核心部件，热释电红外传感器检测人体的存在，采纳光敏三极管构成的电路检测环境光的强度；根据教室合理的信号灯和环环境光信号的识别和推断，对人的身体状况,对教室照明智能控制，避开随着大量浪费电教室。该系统具有报警功能，还采纳了软/硬件“看门狗”等抗干扰措施。该系统能满足各类高校对比明控制的要求,在很大程度上达到节能的目的. 关键词：单片机;智能控制；热释红外传感器;X5045Design of Lighting Control System Based on MCUAbstract：This paper copiously studied using features， lighting requirements and the existing problems of the university classroom， at last a kind of lighting control system based on mcu of classroom was put forward. The system used AT89S51 microcontroller as a core component of the control module. It introduced pyroelectric infrared sensor to detect the existence of human body ， and used circuit which constituted of photosensitive triode to detect the strength of environment 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.Key words: Microcontroller ； Intelligent control ； Pyroelectric infra...
