汽车可靠性数据追踪方法研究

Research of Vehicle's Reliability Information Tracking Method

针对目前可靠性分析存在样本数据量小、故障信息反馈不及时、基础数据缺乏积累等问题,提出一种基于物联网的汽车可靠性数据追踪方法。首先,从数据采集、数据传输、数据处理三个层次研究了物联网相关技术在汽车可靠性数据追踪中的应用价值,从"全面感知"的角度建立了汽车可靠性数据追踪体系的网络架构。然后,研究了全寿命周期可靠性数据产生途径、设计数据统计模型、规范数据收集流程、构建虚拟化的数据库资源池,建立起了汽车可靠性数据追踪模型。最后,开发了一套可靠性分析软件,旨在为可靠性分析评定提供标准、统一、快捷的辅助工具。

A vehicle＇s reliability information tracking method based on the internet of things is established, which arms solve the problems such as small sample size, untimely failure information feedback, lack of basic data accumulation. At first, framework of vehicle＇s reliability information tracking system network is built by overall perception. Technologies, related to the internet of things, are researched on application value, which involves three levels of information acquisition, transmission and processing. Then the building of reliability information pathway, design of statistical model, standardizing of collection processes and the building of virtualized resource pools database are all researched. So a vehicle＇s reliability information track-ing model is found. Finally, a reliability analysis software is given to make evaluation more standardizing, unification and shortcut.
