本文根据英刊“控制和仪表”1984年4月刊登的文章“微型机使得计量有可能成本低”改写而成。此文的主要目的是通过一个实例的介绍,推广单片微型机在仪器仪表中的应用。在测量显示仪器仪表中应用微型机有三个硬件问题影响着成本:价格低的模拟测量电路、A/D 转换器和微型机的选择。本文介绍的采用单片微型机和硅检测元件进行温度测量、信号处理和显示的方案(图1)较好地解决了上述问题。西门子公司的 SAB80215八位单片微型机,芯片内除去一般微处理机的电路外,还有 This article is based on an article in the April 1984 issue of the Journal of Control and Instrumentation, “Microcomputers Make It Possible with Low Costs”. The main purpose of this article is to promote the application of single-chip microcomputer in instrumentation through an example introduction. There are three hardware problems that affect the cost of using micromechanics in the measurement display instrumentation: Low cost analog measurement circuits, A / D converters, and microcomputers. This article describes the use of single-chip microcomputer and silicon detection components for temperature measurement, signal processing and display programs (Figure 1) to solve these problems. Siemens SAB80215 eight single-chip microcomputer, the chip to remove the general microprocessor circuit, there are
