Design And Realization Of The Automobile Type Approval System

Our automotive industry is relatively short history, especially the relevant standards system set up late, the standard systems are all examples of the european standard (ECE), one learns from United States and Japan. Our certification system shall be advanced experience of foreign countries with chinese characteristic of the situation of combined, and formed "Mandatory and Voluntary certification" with chinese characteristics authentication.At present the automobile-manufacturing enterprise for the authentication type is used in the management of the most traditional way, is not aware of the type of information management of the many advantages.Most of the automobile -manufacturing enterprise are using word and excel spreadsheet on parameters collection, sorting and reported. Operating period and easy to make mistakes. And national certification bodies in 2009, with the pattern beginning to improve the system, the number of parameters to the manufacturer reported parameter up more than one.To the manufacturer reported parameter is found-1900 up multiple. If or according to the management and reported, then will be greatly reduced the efficiency of work. This thesis is based on the actual needs of enterprises for the prototype, following extensive investigation and research, developed a type suitable for automotive management system certification.This system enables the management of standardized parameters, systematic, and also improve the internal efficiency of reporting staff.The main advantage of the system embodied in the following points::1. Flexible licensing modelsDisposing the role of each member in the organization by flexible service node anthorization by using flexible data set authorization to guarantee every user can only search and process the authorized data without exceptions. All these flexible authorization managements can meet with the changes of the constant adjustment of the type approval organization and members. 2. Establish a set of flexible parameter templatesDue to the ever-changing report parameters, the situation is also complex and changeable. A single set of template cannot meet with the long-term needs. Therefore, after establishing a set of flexible parameter templates, we can generate a new version which meets the demand by simply configuring some parameters.3. Collecting, collating, and analysing the information of parametersThe information collected are the foundation and basis for type approval parameters which to be reported to the state system. The result of collation and analysis can efficiently guide parts procurement and vehicle manufacturing.4. E-Mail reminders based on Windows systemSending e-mail reminders on time or instantly and make sure that every step of the type approval task is carried out on schedule, which can effectively prevent the unnecessary delays cause by carelessness.5. Net-page optimizations based on new features of ASP NET2.0 and AJAX technologyThe adoption of ASP NET2.0 and AJAX can improve the visiting speed of net-pages, reduce refresh times, result in more convenient operation and user-friendly interface.6. Data information transmissionInvestigate the communications with national organizations such as NDRC, SEPA and CNCA. Uploading report data through internet can save not only a lot of time and human resources, but also prevent the risk of false report.Type Approval System from April 13, 2009 official launch, users of the good. Collection of information to achieve the type certification process of data integration, a high degree of sharing of information, all departments with operational staff and orderly, their duties, reducing the efficiency of the work of link loss, greatly improve the quality and type of certification speed of response. Changes in tracking critical data, business process automation and intelligence to do. And solve the important historical summary of previous user queries data inconvenient, can now be analyzed easily print out the final results and archiving of data storage.The type approval manage system designed in this thesis uses'Browser/Serer'web application architecture, and the realization technique is ASP.NET based on Microsoft .NET Framework3.5, with SQL Server2005 as background database. It possesses system founctions and management of authorizations, type basic parameters and type approval information, e-mail reminder, data analysis searching and data uploading interface.This article from the requirements analysis, system design, system implementation and system testing, the paper introduces the system the whole process of deployment. Through a detailed analysis of user requirements, design data flow diagram, workflow, functional flow charts, etc., through the analysis of early architecture design shows further background database table structure, table related, database configuration and connection to the design, analysis logical structure of data storage.Then, based on the detailed design of the system, based on the system to achieve specific research methods and use of key technologies. Finally, the development of complete systems with varying degrees of testing, and through several renderings key to give the reader an intuitive impression.This thesis is divided into introduction, system technology based system requirements analysis, system architecture, system detailed design, system implementation and testing, the conclusion of the seven parts.
