摘　　要：系统以AT89S52单片机为控制核心,以太网模块作为接口,温度控制系统作为被控对象,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,实现了基于以太网的远程温度监控。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、下限温度自动告警等功能。In this paper,employed AT89S52 MCU as the core component, Ethemet module as the interface and temperature control system as the object, a Dallas chip DS18B20 is applied as a digital temperature sensor to realize remote temperature monitoring based on Ethernet. The system possess of many excellences, 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 discretionarily and an alarm will be given by system if the temperature exceeds the limits.
