Design And Development Of Distance Measurement System For Guided Vehicle Based On ARM

With the increasing passenger throughput of civil aviation airports,the deficiencies of the traditional guidance system of airports are increasingly exposed.In the implementation of the task,the pilot needs to focus on the observation of the road ahead,unable to grasp the safe distance between the guided flight and the guided flight in real time,which brings certain security risks to the airport guidance system.The purpose of this paper is to develop an on-board ranging system for airport guidance vehicle based on arm to solve the technical difficulties in the development,so that the driver can intuitively obtain the interval distance between the aircraft and the aircraft in the vehicle,and can interact with the outside world,effectively reduce the security risks in the process of flight guidance,and promote the intelligent airport guidance system.First of all,the research history and purpose of the project are addressed at various levels in this paper,and the status quo of key device technologies at home and abroad is thoroughly studied,and the direction of development of existing technology and the overall scheme of the project is decided.Secondly,according to the project function in the actual project,the system design requirements are determined from the aspects of practicability,economy and expansibility.Finally,the system's hardware design and software design are completed to check the overall impact of the system's operation.The system designed in this paper is a vehicle borne ranging system based on ARM combining software and hardware,which is divided into hardware platform and software platform.The system hardware platform is composed of arm main control module,laser ranging module,4G communication module,storage module,touch display module and vehicle power conversion module.The design and selection of central and usable hardware modules is completed according to engineering needs.The focus of this paper is on the design of the system software framework,the completion of the design of the software platform,the development of the functional modules software,the design of the system database feature and the development of the vehicle range app.Firstly,the Android operating system is specifically compiled by building a cross compiling environment,which is burned into the hardware platform to complete the design of the system running environment;secondly,the software implementation of laser ranging module and4 G communication module is designed and developed,and their respective data communication and data flow reporting functions are designed and completed,and the communication function between vehicle terminal and tower center is designed through socket;Finally,the system database is designed,and the vehicle ranging system app is designed to realize the functions of driver login and registration,flight information and task status query,task execution and data display.Finally,the key performance parameters of the system and the operation of app are tested and verified.All the performance indicators meet the design requirements,and the app runs well.The use of this design can effectively reduce the security risks in the guidance task process,promote the information intelligent process of the airport guidance system,and make contributions to improve the operation efficiency of the guidance system.
