多线程串口通信技术在DNC系统中的应用

Multithread technology application in distributed numerical control system

以DNC系统中的串口通信为研究对象,阐述了以Visual C++8.0中MScomm控件和Win32API函数作为开发工具,实现DNC系统多线程通信的方法,对这两种方法作了比较,并给出了以Win32 API函数作为工具的联网中的多线程通信程序代码。

In this paper, take the serial communication in the Distributed Numerical Control system as the working object, the method of MScomm and Win32 API function has been studied and contrasted. And a multithread serial communication example on MScomm has been put forward.
