Constitute, the communication of main responsible entity circuit and virtual circuit and PC systems, while completing the default electric fault in PC ends;Entity
Joint action table is then position of the student at the place such as operating desk upper-pilot handle, switch, and Main Function is output student's operation signal
To PLC system or PC virtual circuits part;Virtual Scene System is then driver visual field when simulation is operated the computer, as far as possible really
It is presented to student.
Entity circuit passes through monolithic by PLC, virtual circuit by Electric Appliance Cabinet server, interactive system in tripartite system
Machine is in communication with each other, cooperation, improves the fidelity and actual efficacy of crane simulation training ware.
Compared with prior art, the advantage of the invention is that:
(1) compared with instantly popular all-real object simulation lifting electrical-mechanical system, the system has low cost, updates upgrading
It is convenient, different types of machines can be simulated, with flexibility higher, the advantages of can in time reflect newest control technology.
(2) compared with using the crane simulation training ware of full virtual circuit, the system increased entity circuit, can give
Trainee intuitively experiences, and enhances the perceptual knowledge of the student that undergoes training.In addition for training on maintenance task, entity circuit
Addition so that trainee more quickly and accurately found out in actual maintenance task need check repair electrical equipment.
Meanwhile, entity circuit loop, can according to the wish of system user change define, serve as crane multiple functional entities in
The electric loop of any mechanism, equivalent to all advantages for remaining all-real object simulation lifting electrical-mechanical system, is easy to promote.
