单片机在热量测试仪中的应用

The Application of Single Chip Microcomputer in the Thermometer

本文介绍了由８０３１单片机构成的热量自动测试仪的硬件结构和软件实现过程。叙述了采取４线制及查表法等技术措施，消除铂电阻的非线性，信号线电阻对测温产生的误差。

This paper introduces hardware architecture and software imple- mentation of WRY-1 thermometer of 8031 computer. and describes“four-wire circuit lead method”and“table look up method”for cancelling nonlinearity of platinum resistor and the error of measurement of the single line.
