本文介绍一种在工业现场环境下的微机测量系统，它由８０９８单片机构成下位机，ＰＣ系列的微机作为上位机。下位机由电源、键盘、ＬＥＤ显示器、打印接口和多路开关及Ａ／Ｄ转换器构成。下位机能独立运行，也可通过ＲＳ—２３２串行口与上位机联合工作。这样构成的测量系统抗干扰能力强、可靠性高。适用于工业现场参数测量．并且对上位机的要求降低。
This article describes a computer-based measurement system in an industrial field environment, which consists of 8098 single-chip microcomputer into a crew, PC series of computers as a host computer. The lower computer by the power supply, keyboard, LED display, print interface and multi-channel switch and A / D converter form. Lower machine can run independently, but also through the RS-232 serial port and PC work together. The measurement system thus constructed has strong anti-interference ability and high reliability. Suitable for industrial field parameter measurement. And lower the requirements of the host computer.
