Abstract：For the testing and maintenance training concerning a certain type of missile equipment, this paper proposes an overall scheme for a hardware-in-the-loop simulation, designs a hardware-in-the-loop simulation adapter based on C8051F040 MCU, and presents the hardware structure and software flowchart of the adapter, including the signal acquisition and serial port communication. A testing and maintenance operation process model is also built based on the extended Petri net, and is implemented by using virtual reality technology. The software structure and the detailed flowchart of the process model are given, for the virtual testing and maintenance environment. As a part of the testing and maintenance simulation training system, in the design of the hardware-in-the-loop simulation, the testing and maintenance object is added to the virtual testing and maintenance environment to improve the fidelity of the simulation training system and to solve the practical training problems at the same time.
