基于单片机原理的实验室智能控制系统研究

为了方便教师实时了解实验室（教室）人数,采用STC89C52单片机设计了实验室智能控制系统。该系统智能地控制实验室中各种电源的使用情况,可实现以下功能：通过中断方式使用红外光电开关实时采集实验室人数并根据人数控制实验室中灯和实验桌的电源,通过电脑控制实验室电源的使用情况;并采用2次定时刷新闹钟定时的方式和时钟芯片与单片机内部定时器混合控制方式,使得到达放学时间自动播放音乐,延时关闭电源,同时能显示实验室温度,可通过电脑查询实验室人数等。该系统现已完成,实验表明达到了预期效果。

Study of intelligent laboratory management system based on SCM

In order to enable instructors to know the population of a laboratory（or classroom）,an intelligent system employing STC89C52 SCM is designed to control the power supply of the laboratory intellectually.This system accumulates the population and the number of lights in the room by controlling two infrared photoelectric switches which is connected with interrupted way.The computer software detects the use of the power supply.The system employs the methods of refreshing the program of alarming and the mixing control of timing chip and inner timing module of SCM to play music and turn off the light if the class is over.At the same time,the ambient temperature can be displayed on the LCD.The control system can be used in the micro-electronics laboratory in our university.
