Research on the data processing method of subway vehicle test based on LabVIEW

通过对数据结构以及现有编程软件的剖析,结合用户端对数据的可视化操作要求,研究了一种基于LabVIEW的地铁车载试验数据的可视化数据处理方法。围绕LabVIEW平台的自动多线程特性,在保证简洁操作的目标下降低了软件架构的设计复杂性;运用LabVIEW的TDMS文件读取模块,解决大量数据的读取速度的响应问题;运用内置的Mathscript文本模块,解决车辆制动区间的复杂逻辑判断算法及特征获取算法;运用报告生成工具包,解决了数据分析结果与Word报表的无缝对接,并且高自由度设置报表的属性。该文为地铁列车运行状态检测提供分析途径,为工程上可视化快速处理数据提供了一种方法。

Based on the analysis of t lie data structure and the existing programming software, com-bined wit l i the requirements of tlie users visualization of tlie data, a visual data processing metliod based on LabVIEW is studied. According to the characteristics of LabVIEW multithreading platform, the design complexity of software architecture is reduced under t!ie goal of simple operation; Using LabVIEW TDMS f i le reading module, response to solve the problem of large amount of data read speed ＋ Uin Mathscript text module, solve the complex logic judgment algorithmand feature acquisition algorithmin the vehicle braking range; The report generation toolkit is used to solve the seamless cthe data analysis results and the Word report, and the attributes of the report are sof freedom. In this paper, the analysis method of metro running state detection is presentedmetiiod to visualize and process data q u ic k ly.
