摘　　要：温室大棚生产中,温度是一项影响作物生长发育的重要因素。简易温室往往采用单点或少点测量,由于大棚内温度的不均匀,会造成温度变化时采集不到最高或最低温度。为了解决温室大棚中多点温度采集问题,采用单总线数字温度传感器DS18B20和单片机AT98C52构成多点温度采集系统。系统可以根据使用环境的不同,设置相应的温度上下限,能检测显示传感器的位置编号和温度,超过限定温度时可以报警。In green house,the temperature is one of significant factors to vegetable.Generally,the temperature is diffe rent according to different point.One or two thermometer can not detect the the limit temperatue.In order to measure temperature of different spot in green-house,a digital thermometer based on AT89C51MCU and DS18B20 temperature sensors was designed.The temperature limit can be input according to using environment.The system can display the number stand for sensor in different spot and the temperature of the sensor.A sounder was equipped in the system to alarm for over-temperature.
