摘　　要：为解决传统汽车诊断资源共享受地理位置限制的问题,构建了汽车远程诊断系统,提出了一种基于Internet和3G的汽车远程诊断数据采集方法。根据数据传输流程,结合网络传输特性,设计了各个阶段的数据传输策略,实现了汽车远程诊断数据采集。试验结果表明:所提出的汽车远程诊断数据采集方法实时性高、数据传输准确,可为远程诊断提供有效的数据支持。To solve the problem of geographical limitations of resource sharing in trachtlonat vemcle diagnosis, a remote vehicle diagnosis system is created and a data acquisition method for remote vehicle diagnostics based on Internet and 3G is proposed. According to data transmission procedure, combined with network transmission characteristics, the data transmission strategies in all stages are designed to achieve the data acquisition for remote vehicle diagnostics. The results of tests indicate that the proposed method can provide high realtimeness and accurate data transmission, providing effective data supports for remote diagnostics.
