摘要
在能源日益紧张的今天,节能减排已经凸显得尤为重要了。为了倡导这一理念而设计了一款教室照明控制系统。本系统以STC89C51单片机为控制核心,采用热释电红外传感器、光强检测模块、计数模块作为前端信号采集单元。单片机会根据输入的红外信号、光强信号和人数信号综合控制教室中日光灯的亮暗,以达到节能减排的目的。
The STC89C91 single-chip is used as the kernel of control system for lighting energy saving in classroom. The control system adopts pyroelectricity infrared ray （IR） sensor to detect student＇ s places and use light intensity detection module （LIDM） to detect the intensity of light, and then, the calculation module composed with LIDM and the laser head is used to count the number of student. The single-chips can control the degree of brightness and darkness of the fluorescent lamp based on the input signal of IR, LIDM and the number of people to get the goal of energy saving.
