基于单片机的教室智能照明系统

本文主要介绍了一种AT89S52单片机为核心的教室灯光自动控制系统,针对学校商场等室内灯光的控制现状以及大量浪费能源浪费问题详述了系统的硬件设计和软件设计思路。重点研究了热释红外传感器如何检测人体的存在和光敏三极管构成的电路如何检测环境光的强度。根据教室里的自然条件,系统会通过对人体信号的检测和光照强度的信号识别自动加以判断,构成对教室照明回路的智能控制。该系统控制方便可靠,节约成本性价比高,适用于各种教室商场等室内灯光控制。可以极大程度上节约电力资源的消耗,低碳环保。

This study mainly introduces a kind of AT89S52 single chip microcomputer as the core of the classroom light automatic control system, according to current situation of school shopping malls and other indoor lighting control and waste a lot of energy waste problem described the hardware design and software design of the system. Pyroelectric infrared sensor is mainly studied how to detect the existence of the human and the photosensitive triode circuit how to detect the strength of the ambient light. According to the natural conditions in the classroom, the system can through the human body signal detection and light intensity signal automatic recognition of judgments, constitute the intelligent control of the classroom lighting circuit. High performance/price ratio, and the system is convenient and reliable control, cost saving, suitable for all kinds of shopping malls and other indoor lighting control of the classroom. Can largely save the consumption of power resources, low carbon environmental protection。
