Hardware-in-the-Loop Design of Testing and Maintenance Training for a Certain Type of Missile

针对某型导弹装备检测维修训练实际问题,本文在深入研究检测维修对象和操作过程的基础上,提出了半实物仿真的总体技术方案,设计了基于C8051F040的半实物仿真适配器并给出了适配器硬件结构及软件流程,实现了模拟训练系统对检测维修对象的信号采集和串口通信;建立了基于扩展Petri网的检测维修操作过程模型,采用虚拟现实技术实现了该过程模型并给出了软件结构及具体实现流程,进而构建了虚拟检测维修环境。作为检测维修模拟训练系统的一部分,半实物仿真设计将检测维修对象加入到虚拟检测维修环境,解决了实际训练问题的同时也提高了模拟训练系统的真实感。

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.
