Step 6.3: and then run to synchronous points---" preparing the cooperating type maintenance operation ";
Step 6.3:, advance simulation run according to certain simulation step length according to the Time Advance Mechanism of emulation support platform;
Step 6.4: after all Virtual Maintenance tasks were finished, each module can as one man run to synchronous points---and " end of cooperating type maintenance task ", withdraw from the emulation support platform and finish simulation run.
12. the collaborative maintenance method based on Large-Scale Equipment Virtual Maintenance distributed interactive simulation support platform according to claim 6 is characterized in that: the concrete steps of the Large-Scale Equipment collaborative maintenance operation described in the step 7 are:
Step 7.1: all modules are synchronized to " preparing the cooperating type maintenance operation ", and each module is carried out the operation of cooperating type Virtual Maintenance mutually in phase under simulation step length advances;
Step 7.2: the simulation run administration module upgrades by ordering and receive the operating data message of other each modular simulations, and, all members that add the emulation support platform are managed, monitor and control by the corresponding mutual steering order of button event transmission;
Step 7.3: each maintenance personal's operational module utilizes the data message issue/renewal and the order/reception service mechanism of emulation support platform, by obtain, analyze, processing and transmit operation input data information, and the data message and the state that receive breakdown maintenance emulation module and 3 D stereo what comes into a driver's emulation module upgrade data communication between realization and other federal members and mutual control;
Step 7.4: the breakdown maintenance emulation module constantly receives the mutual control of simulation run administration module and the state of maintenance personal's operational module upgrades and request of data, all kinds of realistic models through the module bottom drive and corresponding numerical evaluation, process analysis procedure analysis and logical operation, and Data Update information is sent to maintenance personal's operational module and 3 D stereo what comes into a driver's emulation module;
Step 7.5: 3 D stereo what comes into a driver's emulation module carries out bottom layer driving, real-time rendering, state renewal, special effect processing and information to all kinds of three-dimensional entity models in the Virtual Maintenance environment and shows;
Step 7.6: data message and the state parameter of 3 D stereo what comes into a driver's emulation module after with all kinds of renewals in the Virtual Maintenance environment sends to maintenance personal's operational module,
Step 7.7: each maintenance personal's operational module carries out the data message display update to visualized operation and demonstration interface, realizes that finally a plurality of maintenance personals carry out various information prompting and the technological guidance in Large-Scale Equipment cooperating type maintenance operation and this process.
