等离子体表面处理监控系统数据通讯的CPLD实现

Application of CPLD Device in the Data Communication of Plasma Surface Treatment Automatic Control System

介绍了等离子体表面处理监控系统数据通讯中数据链路层所需完成的功能 ,提出了用 CPL D完成其功能的方法 :将数据链路层中有限状态机模型与 CPL D在描述有限状态的优势相结合 ,完成半双工的停等协议 .

This paper introduces the necessary function of data link layer in communication of plasma surface treatment control system and presents the method of using the CPLD device to realize it: integrate the superiority of CPLD device when described the finite state with the characteristic of finite state machine model in data link layer, achieved the half duplex wait and stop communication protocol.
