【摘要】：近年来，我国的民航业取得了飞速发展。但是，我国民用飞机的维修技术落后，严重制约了民航业的发展。便携式维修辅助装置(Portable MaintenanceAids,PMA)的设计与实现可以提高飞机维修的效率，促进民航业的进一步发展。 PMA主要应用在飞机维修的工作现场。一方面，PMA为维修人员提供交互式查询的技术资料，提高维修效率；另一方面，PMA还可以为维修人员提供远程维修和故障诊断支持。本文提出了应用于民用飞机的PMA的总体架构以及软硬件的设计方案。为了降低开发的难度和增强系统的可靠性，，本文设计的PMA硬件平台分为实现系统功能的核心板和外围模块电路。根据系统功能的要求，核心板采用北京奥尔斯公司的OURS-PXA270RP核心模块；在核心板的基础上对外围模块的扩展分为电源模块、LCD模块、触摸屏模块、串口模块、USB模块、SD卡模块、LAN模块以及JTAG模块。软件的设计主要包括操作系统Windows CE6.0的定制以及实现飞机辅助维修功能的软件模块设计。首先，对Windows CE6.0的特点和开发流程进行介绍；然后，对操作系统进行了裁剪与定制，并对部分设备的驱动进行了设计；最后，对软件模块的开发方式、数据管理和同步、IETM模块、故障诊断模块进行了设计，并详细介绍了计划工作指令的管理。
[Abstract]:In recent years, China's civil aviation industry has made rapid development. However, the maintenance technology of civil aircraft in China is backward. The design and implementation of portable maintenance aids can improve the efficiency of aircraft maintenance. To promote the further development of the civil aviation industry. PMA is mainly used in the field of aircraft maintenance. On the one hand, it provides the technical information of interactive inquiry for the maintenance personnel and improves the maintenance efficiency. On the other hand, PMA can also provide remote maintenance and fault diagnosis support for maintainers. In order to reduce the difficulty of development and enhance the reliability of the system, this paper presents the overall architecture and the design of software and hardware of PMA applied to civil aircraft. The PMA hardware platform designed in this paper is divided into core board and peripheral module circuit to realize the function of the system, according to the requirement of the system function. The core board adopts the OURS-PXA270RP core module of Beijing Aules Company; On the basis of the core board, the peripheral modules are divided into power module LCD module, touch screen module, serial port module USB module and SD card module. LAN module and JTAG module. The software design mainly includes the customization of operating system Windows CE6.0 and the design of software module to realize aircraft auxiliary maintenance function. First of all. The characteristics and development process of Windows CE6.0 are introduced. Then, the operating system is cut and customized, and some device drivers are designed. Finally, the development mode of software module, data management and synchronous IETM module, fault diagnosis module are designed, and the management of plan work instruction is introduced in detail.
