摘要
随着微电子技术的发展,作为现代电子控制系统的重要组成部分,离散量输入接口处理电路已从传统较复杂的分立元件搭建电路逐步向简单可靠的集成电路方向发展。首先从离散量输入电路基本功能进行介绍,再按离散量输入接口处理电路的发展历程对各种处理电路的实现方式及优缺点进行分析对比,最后以国产HKA03201芯片为例归纳总结出机载航电系统使用集成电路处理离散量信号的优越性。
With the development of microelectronics technology, as an important part of modern electronics control systems, discrete input interface processing circuit from the traditional discrete components to build a more complex circuit is gradually developing towards the direction of a simple and reliable integrated circuits. This paper begins with the basic functions of discrete input circuit are introduced, then the course of development of discrete input interface processing circuit implementation and the advan-tages and disadvantages of various processing circuit were analyzed and compared, and finally to the domestic HKA03201 chip,for example summarized the airborne avionics systems using integrated circuit processing discrete signal of superiority.
