摘　　要：本系统是以AT89S52单片机为控制单元,并采用Dallas单线数字温度传感器DS18B20采集现场温度数据而设计的远程温度控制系统,该系统具有结构新颖、电路简单和控制方便等优点。并可根据需要设置控制温度的上、下限,系统具有超过设置上、下限温度自动报警等功能。In this paper, a new remote temperature monitored control system is introduced. In this system, a AT89S52 singlechip computer is applied as a control unit and a Dallas chip DS18B20 is applied too as a digital temperature sensor. The system possess of many excellenees, including its novel structure, simple circuit and expedient control. The upper and lower limit value of the temperature controlled by this system can be set diseretionarily and an alarm will be given by system if the temperature exceeds the limits.
