Design and Development of An Onboard Intelligent Device based on Jetson NX

This paper presents the design and development of an onboard intelligent device based on Jetson Xavier NX. The device utilizes the computational and recognition capabilities of AI chips to analyze safety signs and provide feedback, assisting in inspections. The technological components and design of the onboard intelligent device are discussed, including the structural framework of embedded systems built with AI chips, as well as the components and applications of embedded systems. The DJI Maverick series models, M30 and M300, are selected and their applications and performance in the power grid industry are introduced. The unmanned aircraft and onboard intelligent device are connected through the DJI Maverick series interface for expansion and control. Edge computing is implemented using a training and computing separation model, and a development roadmap is provided. The designed onboard intelligent device is installed on DJI drones to real-time recognize video streams captured by the drones, which includes modules for data collection, computational analysis, wireless communication, storage, input/output communication, and power interfaces. Through this design, intelligent identification and real-time monitoring of public safety in the power sector can be achieved.
