在工业自动化系统中,经常用到微机与单片机。单片机结构简单、价廉物美,设计与使用方便,且抗干扰性及适应环境的能力强。因而它常被用作工业自动化系统中的前端处理器(也称下位机),深入到现场,采集各种数据及信息,进行简单的处理后送至上位机。同时,它也是一种控制器,接受上位机下达的命令,对现场进行有关的控制。 微机功能强大,人机界面十分友好,能处理很复杂的问题。在工业自动化系统中,通常用作中央处理器(或称上位机),它接收来自下位机的信息和数据,
In industrial automation systems, often used microcomputer and microcontroller. SCM simple, cheap, easy to design and use, and anti-interference ability and adapt to the environment. Therefore, it is often used as the front-end processor (also known as the lower computer) in the industrial automation system. It goes deep into the scene, collects various data and information, and sends it to the upper computer after a simple process. At the same time, it is also a type of controller that accepts commands from the host computer for control of the site. Computer powerful, man-machine interface is very friendly, can handle very complex issues. In industrial automation systems, usually used as a central processor (or host computer), which receives information and data from the next crew,
