摘　　要：利用数字温度传感器DS18820测量机房环境温度,使用单片机 AT89C51控制LCD实时显示现场的温度,通过串口传输到PC机上处理、显示、绘制曲线、语音播报、打印和保存,并可设定温度限进行温度报警, 报警时同时通过GPRS以短信的方式发送到管理员的手机上,方便管理员及时进行火灾处理。通过局域网实现数据的共享。This paper apply digital thermometer DS18B20 to measure temperature of computer room, use MCU AT89C51 to control LCD to display field temperature real-time. The temperature data can be transmitted to PC for processing, displaying, drawing curve, speech broadcasting, pdnting and saving through COM. Also, it can set temperature limitation to alarm. In the same time, the alarm informati on send to the administrator＇s mobile phone through GPRS in short message, so the administrator can deal with the fire disaster conveniently. The temperature data can be shared on LAN.
