The Research And Implementation Of Vehicle Information Systems Service Platform That Support The Car Networking

In recent years, with the rapid development of Internet technology, Internet of things isgradually people are familiar with the term, and put the car into the Internet of things and asan entity in the Internet of things, the data communication between car and car andinformation interaction to construct network system also gradually developed into a car,among them, the vehicle information system for car networking part of the key to the efficientoperation of the system. Vehicle information system (In-Vehicle Infotainment) is to usecomputer, satellite positioning, communication and control technology to provide security,environmental protection and comfortable sexual function and service of automobileelectronic equipment, is part of the smart car, it is as important In the field of automotiveelectronic technology at home and abroad has been the development of more mature, butmore common on the market at present and mature Vehicle information system is limited tousers to provide services for personal cars, the Vehicle information system applied to the realcar networking areas are still In development stage.This paper by national industry and information technology, and faw qiming company jointlydeveloped the "vehicle information systems that support the car networking connection with aservice platform to demonstrate the application" project as the backing, the building issuitable for users of personal car vehicle information system service platform at the same time,between the car and the car, data communication and information interaction between peopleand cars to provide real-time, efficient service form the basic vehicle information systems thatsupport the car networking service platform. Car terminal in the convoy system and serviceplatform CAN choose over3G or WiFi on-board information transmission on the wirelesscommunication technology, car terminal to user information, the car CAN bus data and imagedata, GPS positioning information uploaded to the service platform, service platformaccording to the format of the communication protocol car terminal platform for data analysis,extract the key data, and according to the service center of the data communication format torepackage information, through the Internet to send to the service center, service centeraccording to the result of data analysis was carried out on the car terminal playback operationssuch as remote control, accident.This paper summarizes the main work done is as follows: 1. Introduce the research background of this paper, the vehicle information systemresearch situation and development trend at home and abroad, points out that the developmentof automotive information systems that support the car networking the significance andnecessity of the service platform.2. Compare and analyze the key technology of developing car information systemapplied to, including: navigation technology, data communication technology, processscheduling, RFID technology, etc., choose suitable for car networking technology solutions.3. To support the whole of vehicle car networking information system architecture andfunction to carry on the design and implementation, analysis of the vehicle informationsystem is made up of three parts: the service platform, the convoy system, service centersystem functional requirements, and according to the requirements of design and developmentof the service platform for the division of function modules.4. Introduces the overall structure of the vehicle information system service platform anddevelopment tools such as information, including the design and implementation of thesoftware development environment, the choice of the ways of information storage, thedetermination of the database type, such as the communication protocol of car terminal indetail the definition, classification and function of the service center of information storageformat (XML file format) are described in details5. The service platform of the main function module design and implementation in detail,including the center of the navigation module path planning algorithm in detail, the specificprocess of task scheduling, data communication module design and implementation of theprocess, protocol parsing and conversion module, the principle of image data processing andsystem function module design and implementation, etc.6. Based on the service platform of function and performance test results of the analysis,verification service platform whether meet the car networking system to the requirement ofreal-time performance, safety, parallelism, etc.
