The FMS that is based on Internet is monitored remotely with breakdown diagnostic technology studies

1 overview as mechanical equipment large change, automation, high speed is changed and complication, the breakdown of mechanical equipment is diagnosed also become very complex. A method that solves this one problem is those who build based network is long-range monitor diagnose a system with breakdown. Of mechanical equipment monitor remotely with diagnosing is technology of computer science, communication and breakdown a kind of facility that diagnostic technology photograph combines diagnoses means, this system comes true " mobile is data is not a person " , once equipment malfunctions,change thereby, the passive situation that diagnostic staff is kept constantly on the run. On this foundation, built FMS to monitor as overall as breakdown diagnostic system frame remotely, put forward to raise data to transmit the new method that transmits speed with image. 2 monitoring as mechanical as the overall frame of breakdown diagnostic system equipment remotely to diagnose the system that monitor remotely is an open distributed system, basically manage by system of the equipment that monitor, transmission equipment, transmission passageway, information processing and network the system is formed with diagnostic system, main function of the system is shown 1 times like the graph. Graph the 2 total constructions that monitor diagnostic system remotely for mechanical equipment. The online monitoring system of equipment spot is this monitor the start that diagnoses a center with breakdown remotely, it finishs pair of main condition information that knife robot, machining center exchanges in FMS collect, memory and processing, and simple and easy diagnose, state information classics machines processing hind to be able to pass a network to undertake directly remote transmit, also can break simple and easy examine the result after to transmit diagnostic center directly. Diagnose a center remotely to build the spot image of virtual reality for this user, the treatment status of the equipment of signal imitate spot that comes according to transmitting, by expert and expert system integrated spot and classics network transmit the monitoring information that come, give diagnostic result and give out maintenance is decision-making, to on-the-spot guidance through network feedback maintenance removes trouble. Also can use the site online monitor simple and easy diagnostic result starts the corresponding module that diagnoses central expert system remotely directly, perhaps ask the expert of long-range center, achieve accurate diagnostic result, transmit the result by long-range center to the spot. The online system that monitor monitors FMS of the 3 online systems that monitor the breakdown of the breakdown code that the main place of bottom facility, sensor signal of the component, equipment that can measure directly runs network of signal, control to be able to upload, bottom facility and controller calls the police CRT of equipment of the lamp and signal of condition commutation indicator light, numerical control. The online system that monitor on one hand integrated these signal undertake discriminating to FMS condition, make to urgent breakdown diagnose quickly, make general fixed position to other breakdown. The FMS main control that informs the spot implement undertake corresponding processing, accompany sound and picture to call the police. It is OK that on the other hand the will all information that monitor is machined the form that transmits on the net, send be monitored remotely and diagnose a center, make nicety diagnose by the expert here and expert system. The iformation flow of the online system that monitor is shown 3 times like the graph. Nextpage4 data and image transmit the NetDDE in using LabVIEW to realize dynamic data switch on the local area network, can use a client to apply for mode, server proposal mode and synchronism to transmit 3 kinds of mode. LabVIEW can undertake to data a variety of maths are analysed, OK and intuitionistic indication analyses a result, expert or expert system can get the data after the analysis from now on directly. To know the moving position of FMS equipment spot further, undertake be monitoringed remotely better, diagnose, directive user undertakes the use of equipment and maintenance, monitor in user and FMS diagnose with breakdown undertake between the center real time image of facility moving status is transmitted. To reduce the transmission amount of data of the image on the net, raise the transmission rate of data, use VRML(virtual reality to propose modular language) technology, the FMS that make emulates the 3 dimension graph of the spot, use the animation of VRML and alternant function, make program of FMS3 dimension animation can transmit the control of signal according to support of the people, produce corresponding athletic change, thereby fictitious the working flow that gives FMS spot and working status. VRML2. What 0 written programs can realize trends is alternant, it is namely in the moving process of the program, the motion of the 3 dimension object that controls program place definition in real time with specific signal. The generation of interact basically relies on sensor node and inside insert implement node and method statement. VRML2. The sensor node of 0 has 6 kinds, a few position of the object are changed in the course that they can run in the program, wait like color, position, dimension. The main effect of method statement is to feel change of a few status, pass these change to other node, make a few condition of the object produce change then. Use the animation function that VRML place has and interact, the equipment in FMS system working movement condition carries sensor node, inside insert implement node and method statement emersion come out, those who realize long-range image is fictitious transmit. System of long-range diagnostician of FMS of long-range diagnostician system completes 5 open form main to FMS facility changes knife robot, course carries machining center of center of machining center of car, vertical, turning, horizontal, stereo storehouse, 3 coordinate to measure the diagnosis of machine. This system is main manage system and maintenance library to manage system and machine to learn module by module of knowledge base, database, ambiguous inference, knowledge base. Ambiguous inference module: It is the core of expert system, basically complete the process that searchs breakdown account by breakdown phenomenon, use algorithm of ambiguous and retrorse inference and the nerve network that are based on intent to push manage algorithm to realize a variety of effective inference quickly; Politic to conflict clear up, by sense organ and visual information -- diagnose outside equipment inside diagnostic regulation -- regular degree of confidence from arrive greatly small -- regular itself stores order is chosen, improved inferential efficiency greatly. Faintness matchs the computation that reachs conclusion degree of confidence regularly to use the method that matchs function, namely of premise condition and fact match rate by match function decision, and the matchs value and regular degree of confidence product that the degree of confidence of conclusion is regular premise and database fact. Knowledge base: Include regular library, concept library and graphical library. Regular library is the intellectual part of expert system inference, graphical library is offer in inference detect the graph of information assembles, notional library is regular foundation, regular library is generated automatically by notional library. Knowledge base management: Undertake manage and be controllinged to the knowledge base, complete the of all kinds operation to the knowledge base, include systematic maintenance, daily system office management, use is restricted to manage. Machine study: As FMS move ceaselessly, the likelihood appears new trouble, the certain knowledge in discovering original knowledge base possibly also is incorrect. The machine learns even if the knowledge base with new perfect and original knowledge discovers automatically in maintenance log library. What the compositive formula that this system uses case study and band of guidance study photograph learns algorithm to realize knowledge is automatic get. The operation pattern that diagnoses a center remotely monitors 6 FMS remotely to diagnose a system to be able to divide with breakdown for two kinds of operation pattern: Real time is diagnosed and long-range inquiry is diagnosed. The expert when both main distinction depends on be being diagnosed in real time can pass system of the conference that inspect message and other expert spot to monitor personnel to discuss in real time together, can undertake to the spot according to need real time is monitored, break an opinion to visit a patient at home next. And long-range inquiry diagnoses mode, one kind is spot personnel visit diagnoses a center remotely, application undertakes diagnostic to equipment, long-range diagnostician monitors a system to transmit the information that come over to undertake analytic judging for the basis with the spot, feedback diagnostic result with electronic letter kind to the spot that monitor. Additionally one kind is to pass a network to inquire the expert system that diagnoses a center remotely gets diagnostic a result directly. (The working way that 1) diagnoses mode in real time is the spot the system that monitor reachs the information that monitor diagnostic application to be passed to diagnose a center remotely, by diagnostic center basis the equipment that monitor and information are decided expert and expert system are undertaken diagnostic by what, diagnose a center to decide real time diagnoses time next, inform the spot monitors a system to reach concerned expert to start corresponding expert system, diagnosing time of the agreement in coordination inside, each expert and spot monitor personnel to undertake discussion through inspecting dispatch conference system. If necessary undertake real time is monitored, the treatment flow of spot of diagnostic center imitate and treatment status, final expert makes diagnostic conclusion according to diagnosing a circumstance to reach the information that monitor in coordination and transmit to the spot. (The working way that 2) inquires diagnostic mode remotely is the spot the personnel that monitor reachs the information that monitor diagnostic application to be passed to diagnostic center, input information expert system by diagnostic center or undertake diagnostic through the expert, the expert monitors the analysis of information, processing according to be opposite, get visit a patient at home to decide an outcome, send to the spot that monitor. The expert system that the user also can run to diagnose a center remotely directly through getting online undertakes diagnostic. FMS equipment monitors 7 conclusion remotely to diagnose a network to combine the information between management department, moving spot, diagnostician and manufactory with breakdown rise, use contemporary information to transmit carrier network, can shorten the time that gathers breakdown information, improve the efficiency that breakdown diagnoses, be monitored in coordination and diagnose what achieve pair of equipment different land.
