Internet-based Vehicle Detection System Remote Maintenance Technology Research And Realization

With the rapid development of economy and flourish of the vehicle industry of our country, vehicle inspection technology has gotten fast development. For performance of inspection of using and new vehicles, a large amount of vehicle inspection systems have been established, but maintenance to theirs restricts their usage and generalization.On foundation of deep analysis in various structures of the current vehicle inspection system, the thesis confirms that the maintenance target is vehicle inspection system based on distributed network structure, and brings forward the method of remote maintenance based on Internet about vehicle inspection system, then does deep researches on realization technology of this method and establishes remote maintenance system. This thesis confirms the design principle of system by analysis and compare of the different modes of Internet connection and by research on security of system, technology of network communication, technology of file transmission and technology of remote control. Under the direction of this principle, this thesis gives collectivity design, and confirms physical structure, logic structure and software structure of the system.The thesis has established system model of the remote maintenance using the unification model language (UML), and has carried on the exhaustive description of the system using user case, class case and packet case. Then the thesis has developed and realized the functional model of the file transmission, text communication, hardware diagnosis and remote screen control, and given some user interfaces.Lastly, simulation environment of vehicle inspection system based on distributed network was established. Moreover, by test of every module and experiment of remote maintenance system, the simulation makes good effect.
