【摘要】：现代设备尤其是飞机等大型高科技设备的维修，通常需要复杂的工序与较高的维修技术，现有的维修辅助设备难以提高维修效率保障维修质量。可穿戴技术拥有独特的人机交互模式，，与维修辅助工具结合后能够释放用户的视线与双手，维修人员可以专注于维修任务提高效率。本文设计了可穿戴维修辅助终端的硬件平台，课题来源于国家重大专项“民用飞机XXX技术研究”。可穿戴维修辅助终端以维修任务为中心，以提高维修人员效率作为目标，在设计时充分考虑了维修现场的特殊性，通过人机自然交互的方式弱化了机器结构形态，将人机交互上升到人机融合层面。本文主要研究与设计工作概括总结为： 1.讨论了可穿戴维修系统架构，确立了无线通信连接前、后台的工作方式。前台由维修人员与可穿戴维修辅助终端组成，位于工作现场。后台由本地服务器与远程服务器组成，为前台提供交互式电子技术手册查询与专家技术指导等服务。 2.完成了可穿戴移动维修辅助终端硬件平台设计，包括技术方案论证，单元电路及总体电路设计，六层电路板PCB设计与样机试制，对电路进行了信号完整性分析，探讨了人机交互模式，同时还进行了可穿戴系统集成设计。 3.针对单目显示器要求，设计了VGA信号转换电路并移植了VGA视频驱动程序。针对可穿戴系统的低功耗需求，分别从硬件与软件角度进行低功耗设计，延长了设备使用时间。设计了姿态检测电路与程序。 4.对设计完成后的样机系统进行了总体调试，并对温度、功耗等重要技术指标以及功能进行了测试，技术手册浏览、语音技术支持与图像采集等应用程序均可以在硬件平台上正常运行，测试结果表明，设计达到了指标要求。
[Abstract]:The maintenance of modern equipment, especially large high-tech equipment such as aircraft, usually requires complex working procedures and high maintenance technology. It is difficult for existing maintenance auxiliary equipment to improve maintenance efficiency and ensure maintenance quality. Wearable technology has a unique human-computer interaction mode, combined with maintenance aids can release the user's sight and hands, maintenance personnel can focus on maintenance tasks to improve efficiency. The hardware platform of wearable maintenance auxiliary terminal is designed in this paper. The wearable maintenance auxiliary terminal takes the maintenance task as the center, takes the efficiency of maintenance personnel as the goal, fully considers the particularity of the maintenance site in the design, and weakens the structure of the machine by the way of human-computer natural interaction. The human-computer interaction is raised to the level of human-computer fusion. The main research and design work is summarized as follows: 1. The structure of wearable maintenance system is discussed, and the working mode of background before wireless communication connection is established. Front desk is composed of maintenance personnel and wearable maintenance auxiliary terminal, located at work site. Background by the local server and remote server composition, for the front desk to provide interactive electronic technical manual query and expert technical guidance and other services. 2. The hardware platform design of wearable mobile maintenance auxiliary terminal is completed, including technical scheme demonstration, unit circuit and overall circuit design, PCB design and prototype trial production of six-layer circuit board, and signal integrity analysis of the circuit. The human-computer interaction mode is discussed, and the wearable system integration design is also carried out. To meet the requirements of monocular display, the VGA signal conversion circuit is designed and the VGA video driver is transplanted. Aiming at the low power requirement of wearable system, the low power design is carried out from the point of view of hardware and software, which prolongs the service time of the device. Design of attitude detection circuit and program. 4. The overall debugging of the prototype system after the completion of the design is carried out, and the important technical specifications such as temperature, power consumption and functions are tested, and the technical manual is browsed. The application programs such as voice technology support and image acquisition can run normally on the hardware platform. The test results show that the design meets the requirements of the target.
