【摘要】 随着计算机技术、网络技术日益普遍运用,数控机床走向网络化、集成化已成为必然的趋势和方向。局域网式DNC系统已成为实现数控机床网络化和集成化的重要发展方向。本课题将在吸收国内外相关研究思路和研究成果的基础上,结合我国制造企业实情,对面向串行异构数控机床的局域网式DNC系统及其通讯技术作一些研究。本文在分析DNC系统特点及其发展现状以及我国制造企业现状的基础上,提出了面向串行异构数控机床的以太网式DNC系统,分析了其可行性和优势。研究了以太网式DNC系统的软硬件结构及其通信技术。论文研究了基于嵌入式以太网开发模块RCM2200的串口/以太网通信器的软硬件的设计发法和实现方法,实现了数控机床的串行协议与TCP/IP协议的转换。最后,论文分析了基于MFC的DNC网络通讯程序的设计方法,利用Microsoft MFC和多线程技术实现了DNC主机与通信器(数控机床)的连接与通信研究。对于在系统设计和调试过程中遇到的一些问题,论文也做了分析并提出了解决方案。更多还原

【Abstract】 As the technology of the computer and network are generally used, the networked and integrated has already become inevitable trend and direction of the development of the numerical control machine. The DNC system based on LAN between numeric machines has become the important developing trend of realizing networked and integration development. On the base of studying the relative theories and achievements, the communicating technology of DNC system based on LAN that faced to serial multi-structure numeric control machine has been researched in the paper, according to the current situations in small and middle enterprises. On the analysis of the characters and state-of-the-art, also the actuality of the current situations, the paper puts forward the Ethernet DNC system that faced to the serial numerical control machine, and the feasibility and predominance. Then the paper researches the software and hardware structure of the system, and also communication. The paper studies the design and realizing methods of the software and hardware of serial/Ethernet communicator that based on RCM2200. The achievements have been used to realize the transfer of the serial of numerical control machine and TCP/IP agreement of numerical control machine. Finally, the paper explores the design methods of the communication program of the DNC host computer that based on MFC. The paper also exposed how to use Microsoft MFC and multi-line-route to realize the link and communication between DNC host computer and communicator of numeric control machine. Some problems during the designing and debugging of the system were also discussed and given the solution.更多还原
