Researching Flexible Management And Configurable Implementation Strategy Of Vehicle Test System

With the continuous penetration of Systems-Engineering concepts and Top-Level Design ideas into the design process of armored vehicle electronic information control systems,the current automated test systems for armored vehicles are rapidly developing towards information fusion,functional integration,and distributed synthesis.Because the traditional design concepts included in the equipment design process have not yet been completely changed,the problem of low system configuration efficiency commonly found in traditional automatic test systems has not been effectively resolved,which has largely restricted the vehicle electrical system’s development.In order to improve the ability of the vehicle distributed test system to allocate related test resources during the switching of different test tasks,this paper proposes a flexible management and configurable implementation strategy based on the flexible test idea.The vehicle distributed test built around the vehicle information control unit The system performs business optimization.The specific work is as follows:Firstly,it analyzes the uncertain factors brought about by the test task change on the test system host computer and information control unit software business,and constructs test resources and test task models based on the analysis results,and uses the model parameters to describe the relevant control factors involved in the test task change process.In order to realize the user configuration process of model parameters,a configuration management platform was developed based on object-oriented technology.The platform can classify and output the results of user configuration in the form of XML files,so as to achieve flexible management of configuration results.Secondly,the data transfer mechanism in the original firmware of the information control unit main-control terminal is studied,and the reasons for its failure during the change of the test task are analyzed.According to the analysis results,combined with the dynamic memory allocation technology,an information control unit configuration optimization strategy is built on the basis of the original firmware core module.In this strategy,the USB serial port is used to receive the configuration results of the configuration management platform for the test task,and the data dump address control information under the newly configured test task is recalculated and the buffer is reallocated as needed to achieve Quick adaptation.Finally,a test platform is built to verify the correctness of the implementation of the strategy.The verification results show that the strategy can be successfully implemented and can effectively improve the configuration efficiency of the test system.The implementation of this strategy is based on a unified interface,and its process involves various application technology fields such as software,information,communication interface,and control.Therefore,it can be said that this research is a comprehensive applied engineering research that integrates multiple technologies into one.The research results of this subject will have important application value and guiding significance for the construction of armored vehicle fault diagnosis and condition monitoring system.
