摘要:

针对高温温度计存在体积大、成本高、操作复杂及实际测量依赖电脑而不能独立工作等缺点,研究了温度数据的采集、传输、显示等问题,设计出以STC89C52为核心,基于Pt100温度传感器和液晶1602显示的铂电阻高温温度计。该温度计的测量范围从-200~+500 ℃,精度为1 ℃。实验表明,该高温温度计具有测温范围广、性能稳定、工作可靠、扩展能力强和可独立工作等特点。

Abstract:

In view of the disadvantage of high temperature thermometer such as large size,high cost,complex operation,and dependence on computer in actual measurement,this paper studies the temperature data collection,transmission and display,designs a high temperature thermometer with STC89C52 as its core and with platinum resistor based on Pt100 temperature sensor and liquid crystal display 1602.The thermometer has a measurement range of -200 ℃~+500 ℃ with an accuracy of 1 ℃.Experiment results show that the high temperature thermometer has great temperature measuring range,stable performance,reliable operation,expansion ability and independence from computers.
