【摘要】 随着我国经济的快速发展与汽车行业的日益兴旺，汽车检测技术也得到了飞跃发展。针对所有在用车辆和新车出厂性能的检测，目前国内已建设了大量的汽车检测系统，但对这些汽车检测系统的维护却严重制约了汽车检测系统的使用和推广。 本文在深入分析当前各种汽车检测系统体系结构的基础上，确定以分布式网络结构的汽车检测系统为维护对象，提出了基于Internet的汽车检测系统的远程维护方法，并对其实现技术进行了深入的研究与开发，建立了基于分布式网络结构的汽车检测远程维护系统。通过对各种Internet接入方式的分析比较，及对系统的安全性、网络通信技术、文件传输技术及远程控制技术的研究，确立了系统的设计原则。以该原则为指导，对系统进行了总体设计，确定了系统的物理结构、逻辑结构及系统的软件体系结构。 论文应用统一建模语言建立了远程维护系统模型，并分别用系统用例图、系统类图及系统包图对系统进行了详尽的描述。结合网络通信、文件传输、远程控制及网络编程等技术，编码实现了文件传输、网络文字交流、硬件测试诊断、远程屏幕控制功能模块，并给出了部分实现界面。 论文还研究并建立了分布式网络结构的汽车检测仿真系统。并且在仿真系统中对各功能模块进行了测试，完成了远程维护系统的实验，取得了较好效果。更多还原

【Abstract】 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.更多还原
