Design Of Vehicle Information Interaction Platform Of Airport Guide Vehicle Based On ARM Cortex

This topic comes from the airport application project in Harbin,and the research object is airport aircraft guide vehicle.With the development of social science and technology,the number and throughput of airports are more and more large,and the takeoff and landing of aircraft are more and more frequent.However,the traditional operation mode of the guided vehicle mainly uses the audio call to transmit instructions,in the way of manual sign off,the guidance efficiency is low,resulting in high accident rate and frequent aircraft delay problems.The lag of airport intelligent information construction has become an important factor restricting the development of airport.In view of the disadvantages of airport guided vehicle management,a new type of vehicle information interaction platform for guided vehicle is designed in this paper.Based on the airport application background,the technical scheme is determined,and the embedded technology,Android system,GPS positioning technology and 4G wireless communication technology are used to build a complete hardware platform.In combination with the software design,the information between the guided vehicle lower computer and the server is realized the function of interaction.Part of the hardware platform is based on the "Raspberry Pi 3rd generation b+" with arm cortex series Broadcom bcm2837(B0)as the core.It is equipped with atk-neo-6m GPS positioning module,ZTE me3760?V2 4G communication module,12 V to 5V power supply module,SD card memory module and LCD touch screen.The software design part includes using Ubuntu system to build cross compiling environment,configuring and compiling Android operating system kernel,generating image file and writing it to "Raspberry Pi 3b+" development board,launching Android operating system with uboot,configuring GPS serial port driver,setting 4G module networking.In this paper,the guided vehicle information interactive app is made,and thelocal My SQL database is designed for data storage and call.It is connected to the server through the socket programming TCP / IP transmission protocol,and the terminal GPS positioning data is acquired in real time and uploaded to the server.At the same time,receive server information,store,display and feedback,including guidance task,crossing prompt,danger warning and planning path.After registering and logging in,the guidance task is selected by the driver,calls the third-party map software API to locate in real time,obtains the longitude and latitude analysis and display of path points,and realizes the navigation function.The platform has the characteristics of strong practicability,portability and easy operation.The equipment is installed in the center console of airport guide car to realize the function of information exchange,which has high practical value and application prospect.
