[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.
