serial device server meaning in Chinese

设备服务器

Cnc machine tool network based on serial device server
基于串口服务器的数控机床组网
In it , the nc machines are connected to the serial device servers , and the serial device servers are connected to the lan which is using tcp / ip protocol
在该dnc架构中,数控设备通过rs - 232串口连接到串口服务器,串口服务器直接连接到基于tcp / ip协议的车间层局域网。
In this thesis , on the basis of researches on serial communication , remote call , drip feed and synchronous control , a dnc system based on rs - 232 serial device server with the functions of remote call and drip feed is put forwards to solve the problems , and the framework of the dnc system is given
针对上述这些问题,本文在研究了串口通讯技术、 nc程序远程调用技术、在线加工技术、并发通讯技术等相关技术的基础上,给出了支持远程调用及在线加工的dnc系统的解决方法,研究了基于串口服务器的dnc系统架构。
