Research On The Intelligent DNC System Based On AdHoc Wireless Network

Highly automated and digital CNC processing equipment has been widely used in the production activities of modern enterprises, how to informatization and the large nc equipment intensive has become a modern enterprise production and management and to the management of the important research field of machinery and electronics technology. By Distributed Numerical Control system(DNC, Distributed Numerical Control) to the Numerical Control processing equipment for centralized management and online monitoring become a has the broad prospects for development of efficient solutions. The technology to the traditional machine as the main body of the mechanical processing technology to the network and information technology, become the development direction of modern enterprise production management.This paper first discusses the DNC system in the aspects of network mode, machine communication research present situation, existing problems and development trend. At the same time discusses the emerging wireless network technology in recent years, the development background of Ad Hoc wireless Ad Hoc network and the technical features, will be Ad Hoc technology applied in DNC system is further discussed the innovative concept, in order to solve the traditional cable DNC system wiring difficulties and the problems of ordinary small wireless network coverage, and based on this, advances the concept of intelligent DNC system based on Ad Hoc. Considering the actual function of DNC system in industrial site needs, from DNC intelligent terminal Ad Hoc architecture, machine tools, communications and other aspects, the overall hardware and software framework of intelligent DNC system was put forward.This paper mainly researches the DNC system Ad Hoc organization structure and cover transmission performance. Based on the actual situation of the industrial field, applicable to DNC system Ad Hoc access protocol, routing protocol and topology structure selection and design. This paper proposes a topology control algorithm based on position- energy constraint to optimize the network performance. At the same time, based on the traffic load and node power, using OPNET, a leading network simulation and simulation software on the network of the whole system performance simulation and optimization, and the results of the simulation system is systematically analyzed to ensure that the system has reliable performance.Then, based on DNC system in nc machine tools and workshop server communication, data acquisition system, the requirements of remote monitoring, the DNC intelligent terminal software and hardware system is designed. Specific work includes selection and design of the hardware circuit, Ad Hoc node hardware implementation and driver of transplantation, u Clinucx tailoring and transplantation of the operating system, etc. Use based on B/S architecture, on the other hand, the general Web Sever IIS technology, design writing intelligent DNC integrated management system, realized the automatic NC NC program transmission, information database management technology, information processing and device status real-time monitoring, and other functions.Finally, we do experiment and performance analysis of the system, to verify that the design is correct and completed.
