Design of virtual maintenance training system based on circuit component model

The technology of virtual maintenance has been spread to the field of circuit components by this paper. This virtual-maintenance system interjects with circuit simulation and virtual-reality. The three- dimension model of the circuit board built in virtual reality software is imported in this system, and the Simulation Program with Integrated Circuit Emphasis (SPICE) had been used. The problem of getting no macro model of Boolean calculation component had been solved. A useful, economical and popularized virtual maintenance training system was built. By using this system, the trainers can be more familiar with the circuit board, as well as know its principle. In this way, the trainer will improve his ability in maintenance a real circuit board.
