基于CPN飞机超短波电台主最低设备仿真分析

Simulation of main minimum equipment of VHF radio based on CPN

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。

Main minimum equipment is an important part of scientific maintain system. Colored Petri nets have many pecu- liarity such as command card colour and hierarchical network, and is applied to the modeling and simulation of all sorts of sys- tems. The modeling and simulation technologies are adopted in the study of main minimum equipment. The VHF radio of plane has the receiving and transmitting functions. The receiving function is considered only in the analysis. On the basis of the de- scription of system hypothesis and structural mode, the system components are numbered. In combination with the superiority of CPN modeling language, the modeling and program design of VHF radio were conducted with CPN. The model was simulated by using CPN-tools program package. The simulation result which is helpful for analysis and comparison is offered in this paper.
