主最低设备清单是科学维修体系的重要组成部分,彩色Petri网具有令牌颜色和层次网络的特点,可以对各种系统进行建模和仿真。将建模仿真技术应用到主最低设备研究中,飞机超短波电台具有接收和发信的功能,分析时只考虑接收功能,在对系统进行假设、对结构形式进行描述的基础上,对系统元件进行编号,结合CPN模型语言的优势,并用CPN对超短波电台进行了建模,进行了程序设计。最后运用CPN tools工具对所建模型进行了仿真,给出了仿真结果,可供分析、对比研究。 The MMEL is an important part of the scientific maintenance system. Colored Petri nets feature tokens of colors and hierarchical networks to model and simulate various systems. The modeling and simulation technology is applied to the research of the main minimum equipment. The aircraft UHF radio station has the function of receiving and sending letters. Only the receiving function is considered in the analysis. Based on the assumption of the system and the description of the structure, the system components Number, combined with the advantages of CPN model language, and using CPN to model the UHF radio station, the program design. Finally, CPN tools were used to simulate the model, and the simulation results were given for analysis and comparative study.
