【摘要】：便携式维修辅助设备能够为用户提供电子技术手册、语音通话、拍照等功能，使得维修人员通过无线网络与维修服务中心进行通信，获得远程技术支持。根据民航维修的需求，，结合嵌入式技术、低功耗技术设计了低功耗便携式维修辅助设备。本人的主要工作内容为： 1.完成了便携式维修辅助设备硬件平台的搭建，包括维修设备硬件各功能模块芯片的选型、电路图的设计、PCB的设计；对设计的维修设备的硬件进行调试；从金属材料屏蔽性、尺寸、散热处理和接口多样性等四个角度设计了便携式维修辅助设备的外壳。 2.根据对实际测得的维修设备各模块耗能分析，并综合常用的软件低功耗方法，提出了三种降低维修设备功耗的方法，即修改嵌入式处理器的时钟配置、设计屏幕保护程序和转换处理器的电源模式。 3.在所搭建的硬件平台上对所设计的低功耗方案进行了验证。实验所测得的维修设备总体功耗显示，我们设计的低功耗方法能够较大的降低设备的功耗。 4.对整个系统的功能进行了测试，这些测试包括电子技术手册查询、拍照、语音通话等功能。测试结果表明整个系统能够正常的提供这些功能。
[Abstract]:Portable maintenance aids can provide users with electronic technical manuals, voice calls, photography and other functions, so that maintenance personnel through wireless network to communicate with the maintenance service center, access to remote technical support. According to the requirement of civil aviation maintenance, low power portable maintenance auxiliary equipment is designed with embedded technology and low power technology. My main work is as follows: 1. The hardware platform of portable maintenance auxiliary equipment is built, including the selection of each function module chip of maintenance equipment hardware, the design of circuit diagram and PCB, the debugging of the hardware of the designed maintenance equipment, the shielding of metal material, The shell of portable maintenance auxiliary equipment is designed from four angles: dimension, heat dissipation and interface diversity. 2. Based on the analysis of the energy consumption of each module of the maintenance equipment measured in practice and the common software low-power methods, three methods to reduce the power consumption of the maintenance equipment are proposed, that is, to modify the clock configuration of the embedded processor. Design screen saver and switch processor power mode. 3. The low power consumption scheme is verified on the hardware platform. The overall power consumption of the maintenance equipment measured by the experiment shows that the low power consumption method we designed can greatly reduce the power consumption of the equipment. 4. The functions of the whole system are tested. These tests include electronic technical manual query, photo taking, voice calling and so on. The test results show that the whole system can provide these functions normally.
