Design And Implementation Of On-board Multimode Gateway Application Platform

Based on the scene about applications of on-board multi-mode intelligent gateway,we propose a related application platform.Multiple application scenes are implemented on this platform,including remote control of the vehicle,vehicle renting system and image synchronization between mobile devices and the intelligent gateway.The intelligent gateway is implemented on a built-in hardware platform with the Android operating system.The gateway is responsible for network messages sending.The user mobile device part offers services under different new scenes with the application platform.The car simulation terminal simulates a vehicle and lower the developing costs.It is tested that this application platform is able to implement multiple application scenes of on-board intelligent devices and offer related services.The thesis is divided into seven chapters as follows.Chapter 1 introduces the background and importance of this subject research,together with the main content of the thesis and the arrangement of chapters.Chapter 2 analyses the common and typical application scene of this platform.This part also discusses the requirement of the on-board intelligent gateway,the user mobile device and the car simulation terminal,proposing the main design plan.Chapter 3 sets forth the detail implementation scheme of the on-board intelligent gateway according to the design proposed in Chapter 2.This part gives a detail analysis of the hardware part and build up the software environment.Chapter 4 proposes two different application scenes of the user mobile device.This chapter amply explains the workflow of the control software developed,together with several important modules' working principle.Chapter 5 analyses the detail implementation plan of the car simulation terminal.The implementation steps and principles of the terminal are elaborated with the hardware and the software The CAN communication details are also set forth together with several modules' implementation.Chapter 6 introduces how to build up the whole hardware platform and the testing environment.The remote control scene,the vehicle renting scene and the image synchronization scene are all tested.Test results are analyzed while the possible solutions to problems are discussed.Chapter 7 concludes the result and looks ahead to the possible improvements.
