【摘要】：CDU是飞行任务管理的主要人机界面,因而也是研制飞行训练模拟器需要研制的重要仿真部件。本文通过对CDU按键功能和页面逻辑的研究,总结了一种较为通用的页面逻辑,提出了一种软硬件结合的仿真方案,该系统由下位机的输入/显示模块和运行在PC端的逻辑单元组成。输入/显示模块是包括显示屏、按键、处理器和网络模块的硬件系统,该模块负责将按键信息发送到上位机的逻辑单元,并将接收到的信息显示在屏幕上。处理器使用STM32F1,CORTEX M3系列ARM,在外围扩展了使用SSD1963驱动的5寸液晶显示屏以及ENC28J60网卡。选择MDK作为开发环境,在ARM上移植了u C/OS II嵌入式实时操作系统,u C/GUI嵌入式图形支持系统,Lw IP嵌入式网络协议栈。实现了显示和通信的功能,并保证了多任务的调度。逻辑单元是运行在PC端的程序,使用Qt库开发,模拟了CDU的页面逻辑功能,能接收输入/显示模块发送的按键信息并进行处理,发送正确的页面信息给输入/显示模块,让其能正确显示内容。该部分中详细分析了CDU页面直接的关系,分为页面内逻辑和页面间逻辑,使用面向对象的思想仿真实现了这些功能。使用SQLite数据库以资源文件的形式存储页面信息,方便了将来的扩展。定义了通信标准,使用了Qt中封装好的UDP/IP类实现了2个模块的协同工作。实验表明,该方案切实可行。实现了CDU的输入/显示功能,保证了上位机与下位机的隔离,并因使用资源文件其程序的扩展性和可维护性得到了提高,是一种有效的CDU仿真方案。
[Abstract]:CDU is the main man-machine interface of flight mission management, so it is also an important simulation component to develop flight training simulator. Based on the research of CDU keystroke function and page logic, this paper summarizes a general page logic, and puts forward a simulation scheme combining hardware and software. The system consists of the input / display module of the lower computer and the logic unit running on the PC. The input / display module is a hardware system including display screen, keystroke, processor and network module. The module is responsible for sending the keystroke information to the logic unit of the host computer and displaying the received information on the screen. The processor uses the STM32F1 CorTEX M3 series ARM, and extends the 5-inch LCD screen driven by SSD1963 and the ENC28J60 network card. Using MDK as the development environment, the embedded graphics support system of U C / C / GUI is transplanted into the embedded real-time operating system of UC / OS II on arm, and the embedded network protocol stack of LW / IP is introduced. The display and communication functions are realized, and multi-task scheduling is ensured. The logic unit is a program running on the PC, which is developed by using QT library, simulates the page logic function of CDU, can receive and process the keystroke information sent by the input / display module, and send the correct page information to the input / display module. So that it can display the content correctly. In this part, the direct relationship of CDU pages is analyzed in detail, which is divided into intra-page logic and inter-page logic, and these functions are realized by object-oriented ideological simulation. Use SQLite database to store page information in the form of resource files, convenient for future expansion. The communication standard is defined and the UDP / IP class encapsulated in QT is used to realize the cooperative work of two modules. The experiment shows that the scheme is feasible. The input / display function of CDU is realized, and the isolation between upper computer and lower computer is guaranteed, and the expansibility and maintainability of the program are improved because of the use of resource file, so it is an effective simulation scheme for CDU.
