摘要
传统方法测量温湿度多以热电阻和热电偶等温度敏感元件,但都存在可靠性差,准确度和精度低的缺点。本设计采用VI界面,在单片机平台上完成对温度和湿度的实时测量。文中简介了该系统的设计方案、分模块测试了系统的可靠性。结果表明,该系统操作简单、可视性好,运行稳定,可靠,能够满足技术更新的要求。
The traditional method for measuring temperature and humidity, most use the thermal resistance and thermocouple temperature sensitive element. But it has poor reliability, accuracy and low accuracy by traditional method. This design adopts the VI interface, complete the real-time measurement of temperature and humidity in the single-chip platform. This paper introduces the design scheme of the system, the test of the system reliability. The system designed in the commissioning and testing laboratory, shows that this design based on the temperature and humidity of LabVIEW monitoring system of function and index all reached the technical requirements.
