摘要
介绍以MCS-51单片机系统和传统的温度检测元件热电偶相结合的温度测量系统,文章对其实现方案进行了系统的设计,对其模拟信号的输入输出电路进行分析,并对系统进行了误差产生原因的分析。
The Muhifunctional Temperature Measurement Instrument introduced in the thesis is developed by combining a MCS -51 8-bit microcontroller system with a conventional temperature measurement component-thermocouple. The schema is put forward and the input and output circuits of analogy signal are studied. It also studies causes of errors.
