摘 要
Intel 8086 是一个由 Intel 于 1978 年所设计的 16 位微处理器芯片，是
x86 架构的鼻祖 , 作为微机原理课程设计的选型，具有易学易懂的特性。本次
试验使用 8086 实验箱，进行可燃气体检测并将其显示到数码管和 LCD屏幕的
实验，可燃气体检测主要用到了 AD采集与数模转换，将采集到的可燃气体浓
度相关电压通过相应运算放大的电路和比较器处理为稳定的模拟信号， 然后送
到 AD 转换芯片将模拟 量 转换到数 字量之后经操 作系统 将结果送至 数码管 或
LCD进行 对应数 值显示。 在 LCD显示 中，用到的 时序或者 相关显示 指令可以参
照 LCD技术文档 转化到相应 汇编语言 ，整体设计 中注意接线 与实验箱 及模块的
好坏。本实验 意在增 进学 生的动手能力 和对微机原理的 形象认识 ，对我们接触
到更多 的东西 有一个 触类旁 通的作用。

Abstract
Intel 8086 whitch is designed by Intel in 1978, is a 16-bit microprocessor
chip.It’s the ancestor of x86 architecture. As a selection of microcomputer principle
curriculum design, It has the property of easy to understand. The 8086 experiment
using a test box, perform and display the combustible gas detector to test digital and
LCD screens, the main use of combustible gas detection AD acquisition and digital to
analog conversion, will be collected by the combustible gas concentration-dependent
voltage corresponding calculation after the amplification process and a comparator
circuit for the stable analog signal is then supplied to the AD converter chip analog to
digital converter via the operating system or the result to the digital value
corresponding to the LCD display. In the LCD display, used in sequence or related
display commands can refer to the technical documentation converted to the
corresponding LCD assembly language, pay attention to the overall design and quality
of the experimental box and wiring modules. The experiment is intended to enhance
the abilities of students and on the principles of computer image understanding, we
are exposed to more things have an analogy role.
