Summary: Long-range visit and operation are the issue of a heat that information age manufacturing industry studies. The system of machining center numerical control that the article discussed the network equipment that is based on the computer to string together a communication and TCP/IP implementation join to go up in wide area newwork to go up in bureau city net to join in detail undertakes the design of soft hardware of long-range visit and pilot and implementation. Competition of production globalization, market turns white-hot is the trend of a development of current manufacturing industry and characteristic. The globalization of manufacturing industry basically behaves the dispersing that makes a system in the enterprise to change the internationalization that reachs client and supplier. Globalization asks same company is interior, between enterprise and equipment supplier and work in coordination between enterprise and client, share information. Support is opposite the productivity of high quality and product, good after service and flexible online project technology to serve remotely / support of long-range and online project raised strong demand. As the wide application of the flying development of computer technology and contemporary communication technology and Internet/Intranet, support of long-range and online project and the research that handle remotely are becoming current research heat. In the long-distance service of equipment breakdown diagnoses a system in, the long-range monitoring of equipment is implementation long-range and online diagnose the base that reachs project technology support. At present a few sophisticated treatment equipment of manufacturing industry are mixed product, also set use goodly at long-range communication pilot to expand interface is mixed with go up a machine the whole agreement that has communication, these characteristics were the long-range visit that realizes product and equipment, operation and control to offer good foundation and condition. The article it is an object in order to be the same as the machine tool of MAHO numerical control of lab of FMS of research center of aid university CIMS. The long-range supervisory system that discusses long-range monitoring and machine tool of visit MAHO numerical control in detail (the design of the total construction of RCCNCS) and soft hardware and implementation. If the functional analysis graph of the function of overall design system of 1 RCCNCS of flow of function of RCCNCS of machine tool of graph 1 MAHO and purpose RCCNCS pursues 1 is shown. MAHO machine tool uses DNC job pattern (automatic mode) , station of monitoring of this locality cuss asks to pass monitoring software to have corresponding operation and control to the machine tool according to the job. PC monitoring station is equipment of telenet sth resembling a net and connective of system of machining center numerical control the equipment intermediate, the information of main processing has: Operation of clavier of simulation machine tool and screen show; Gather information of machine tool state and information of real time treatment; Issue control order to the machine tool, dominate all sorts of actions of the machine tool; The need that visits according to the network undertakes network information processing, coordinate the work of equipment of telenet sth resembling a net; To the treatment of the machine tool condition undertakes imitate; The fluctuation of machine program is deferent, the BTR job mode that realizes a machine tool. Graph the intermediate equipment that the station of monitoring of PC of block diagram of construction of system of 2 RCCNCS regards machine tool and network equipment as communication, realize cuss of telenet sth resembling a net to visit the end that dominates machining center through undertaking corresponding coming with equipment of telenet sth resembling a net. In addition, PC monitoring station still is mixed for the staff member safeguard personnel to offer support of material of technology of a few projects and breakdown to diagnose support. If the graph is shown 2 times,the total construction of structural design RCCNCS is designed. Join the rock-bottom PC monitoring on net of industrial spot aether stands, the monitoring software that passes moving machine tool undertakes real time monitoring to system of machining center CNC, carry of superstratum control lead plane controls software remotely to be able to come true to undertake controlling to station of spot PC monitoring all right (this also move to control software) remotely on PC monitoring station at the same time. Lead plane of control of a superstratum can control ground floor many monitoring stand. Station of rock-bottom acting monitoring collects CNC to process information and stock system of enterprise interior database through the local area network. When system of CNC of long-range PC visit and machining center of control this locality, it visits the enterprise server on join ISDN/Internet through the network above all, the control that requests station of monitoring of this locality PC to enterprise server counterpoises. Enterprise server undertakes corresponding qualificatory attestation and accredit inform monitoring of this locality PC of the station, start long-range control software and after the setting is corresponding working mode, ability of long-range control PC has operation and control to system of machining center CNC. When long-range control PC and station of this locality monitoring build join hind, the operation result that the operation that long-range PC logarithm controls a system and logarithm of station of monitoring of this locality PC control a system is same, all functions that can fulfil monitoring of this locality PC to stand. The design of software of communication interface of graph 32 CNC is in RCCNCS design, what machine tool of MAHO numerical control uses is the numerical control operating system of Philips, operating system of Philips numerical control has his whole communication agreement. Operating system of Philips numerical control has agreement of communication of two kinds of data, namely % agreements and LSV/2 agreement. % agreements are the common communication agreement that machine program delivers to use up and down when be being used at CNC to be in handiwork to operate state, cannot use in be operated remotely. LSV/2 communication agreement is the agreement that when operating system of Philips numerical control is long-range operation only, offers. When using this communication agreement, CNC is in long-range control mode (DNC mode) . Right now, the monitoring station operation to the machine tool and the effect just the same that this locality handiwork operates. Program of this systematic communication interface used the LSV/2 agreement of system of Philips numerical control. If the graph is shown 3 times,monitoring station computer sends the order flow of data. Send the each frame data that just transmits to include frame head DLE(ASCII to pile up 10H)STX (ASCII to pile up O2H) , data paragraph (the 120 longest ASII character) with frame end DLE(10H)ETX(03H) and the desired result that after passing a these character to pass different or operation, get. Frame desired result has first after receiving debit to receive one frame data, if examine result and the desired result that receive identical, receive this frame data, ask to send otherwise just transmit this frame data afresh. The communication stringing together a mouth that language Visual C++ has standardization with Visual Basic uses current visible programming package () of MS Comm component, the workstation that can develop corresponding monitoring software to realize a local area network to go up according to the communication agreement of above is right the control of system of machining center CNC. The PC monitoring that soft hardware of pilot of station of 3 PC monitoring realizes join to go up in industrial aether net stands to realize operation and control to the numerical control system of machining center, provided good basis to realize long-range control. After monitoring software development is finished, the visit attributive with the long-range control application software that should find to be able to be based on TCP/IP to move only and very relevant setting and user countersign, with respect to the operation that can realize long-range main engine to stand to monitoring of this locality PC. This system controls software remotely to use Symantec PcAnywher32. Function of this application software is powerful, should install only correct, long-range PC can use this software to come true to control the computer of this locality via Internet, achieve the goal that controls system of machining center CNC remotely thereby. The solution that PcAnywher32 is the ideal that long-range control, file is transmitted and corresponds commonly is decision-making slightly. There should be PcAnywher32 software on two PC only, it can control another PC remotely from a PC, the document is transmitted on two PC and synchronism changes folder, join all sorts of online services, the link that builds a network becomes a node on the network, the agreement that PcAnywher32 uses is TCP/IP, the setting that moves on wide area newwork is very simple, the physics that its use joins equipment is device of common network physics layer.
