摘要
介绍了由MCS -51单片机和恒温式热量计所构成的热量自动测试仪的硬件组成和软件系统开发研究过程。着重介绍了为保证测量精度和计算精度而采取的内外筒双铂电阻同时自动测温、4线制连接法和查表方法 。
This paper introduces hardware architecture and software implementation of DRY-1 thermometer of MCS-51 computer,“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 were studied The research and development of the hardware components and software system in DRY-1 thermometer of MCS-51 monolithic processor was introduced in this paper“Four-wire circuit linkage method”and “Tabular seeking method”for cancelling nonlinearity of platinum resistor and the measurement error of the single line were also put forward
