Design And Development Of Mobile Phone Client Based On Internet Of Vehicles

With the rapid development of China's automobile industry,the number of vehicle ownership has been rising,which brings convenience to people to travel and also accompanied by the emergence of urban environment and traffic problems.At present,urban traffic congestion has seriously affected people's life and economic development,which has become an urgent problem to be solved in urban development.In recent years,the rise of Internet of Vehicles technology has provided a new direction for intelligent transportation system.Internet of Vehicles is an intelligent transportation system that integrates internet technology,wireless communication,positioning and navigation,big data,cloud computing,artificial intelligence and environment awareness to achieve safe,reliable,fast,intelligent and humanized intelligent effect.This subject relies on the science and technology planning project of Liaoning Provincial Education Department in 2017,"Research and development of the new energy vehicle Internet of Vehicles system",to carry out the research of the mobile phone client of the Internet of Vehicles.The research work of this thesis is as follows:(1)The task of this thesis is based on the design and development of the Internet of Vehicles client.Firstly,through detailed analysis and research on a large number of related technical literatures,the development status and basic system architecture of the Internet of Vehicles technology have been deeply understood and mastered.(2)Based on the above,focusing on the detailed analysis of the technical requirements of the smartphone client part of the Internet of Vehicles system,and proposing the design scheme of the mobile phone client,adopting a modular design for the overall client,and classifying the technical requirements of the clien,the system can be divided into four basic modules:login,vehicle management,data management,and map navigation.(3)After completing the modular design of the system,in order to realize the information interaction between the mobile phone client and the vehicle T-BOX,the mobile phone client and the cloud platform,the communication mode between the components of the system and the communication protocol required for the data interaction of the system are determined.Among them,the communication between the client and the vehicle T-BOX adopts direct connection WiFi and Bluetooth mode;the communication between the client and the cloud platform adopts 4G mobile communication mode.(4)According to the technical requirements of the Internet of Vehicles client,detailed design instructions for the client software.Firstly,it analyzes the workflow of the mobile client,and briefly introduces the Android,Baidu map API and other related technologies involved in the design and development of the mobile client software.Theoverall client design is divided into five interfaces,namely the "Login interface","Main interface","Vehicle management interface","Map interface","Data management interface".The client is convenient for the user to obtain the working status parameters(including historical data query)of the vehicle from the vehicle T-BOX or the cloud platform anytime and anywhere through the smart phone,and can also access the Baidu map API to provide the user with real-time positioning information and navigation function of the vehicle.(5)Finally,Bluetooth communication,wireless network communication and 4G communication function test were carried out on the mobile phone client.Experimental tests show that the mobile phone client can establish direct communication with Bluetooth and WIFIF between the vehicle T-BOX and 4G communication with the cloud.And complete the data interaction.In addition,the program installation/uninstallation,mobile phone compatibility and cross-testing of different brands of smartphones have been completed.The experiment proves that the developed client software has certain compatibility and cross-cutting.
