摘要
介绍一种用 C语言实现单片机数据处理的方法 ,它能重点实现对不同型号热电偶分度表的自动查表、热电偶温度测量的非线性修正 ,以及用热敏电阻换算法 ,进行冷端温度自动补偿计算 .文中还论述数组指针在数据表格中、插值计算在非线性修正中的应用 .实践表明 ,用软件数据处理代替传统的硬件测量系统 ,具有硬件结构简单、使用灵活、测量精度高等优点 .
Measuring temperature with thermocouple, a method of C language implemented data processing by one chip microprocessor is presented, laying stress on application of array pointer to data list and application of interpolation calculation to nonlinear correction. By this method, automatic look up different types of thermocouple scale lists can be realized; nonlinear correction themocouple measuring the temperature and autocompensatedly calculating the temperature at cold junction by thermistor conversion can also be realized. As indicated by practice, the use of software data processing as a substitute for conventional hardware measuring system is characterized by simple in hardware structure, flexible in service, and high in measuring precision.
