Maintenance Training System Development, Based On A Military Radio Station Of The Circuit Simulation

The application of digital technology and SLSI in military electronic device improved the battle effectiveness, however, it becoming difficult to maintenance and testing.The modern methods of electronic device maintenance are composed of circuit simulation and modern testing method. Based on platform of computer hardware and software and adopting such knowledge as electrology, graph theory, analysissitus, the circuit simulated by computer is an important embranchment of simulation. Moreover, this technology can be used in electronic circuit design, analysis, simulation and manufacture. The electronic simulation can fast judge the states of electronic device and can assist diagnostician of default. Simulating the military equipment's electronic circuit and integrated the result into an application software is a feasible case for resolving the problem of less equipment.The maintenances and training system of a military transmitter-receiver based on electronic circuit simulation was developed for a new type transmitter-receiver which is complex and difficult to maintenances. Meantime, the equipment accouter so less that make difficult to teach in military school. Utilizing SPICE and visual simulation, this software is a windows program developed by MFC. Furthermore, for convenience to query maintenances knowledge of transmitter-receiver, the module of history diagnosis querying was embodied.The system revealed the circuit theory of transmitter-receiver. The electronic circuit was simulated by SPICE and was displayed by visual simulation, which adopted OGRE as its engine. For the diagnosis knowledge of technician accumulating, the system implemented query module based on ODBC.After detailed demand analysis, the project was developed by prototype method and it actualized required function and has been used by army.
