摘要:

        提出了一种基于大数据挖掘技术的、用于汽车运行工况数据采集设备的故障诊断方法。该方法依托中国汽车测试工况(CATC)项目和内蒙古道路运输企业节能降耗监控技术研究(NJ-2017-8),运用了k-means 故障模式聚类算法、诊断状态参数Apriori 关联规则、及相关性分析算法。并进行了案例实证分析。结果表明:采用k-mean 算法能有效分析数据采集设备的故障模式,Apriori 算法挖掘出的数据采集设备特征参数之间的关联规则与相关性能,有效地找出数据采集设备的故障环节和原因;与设备实际维修试验结果相符。因此,该方法可为数据采集设备的运行维护与管控提供参考。

Abstract:

A fault diagnosis method of vehicles driving cycle data acquisition devices were proposed based on a project sponsored by the China Automotive Test Cycle (CATC) and the Research on Monitoring Technology of Energy Saving and Consumption Reduction for Road Transportation Enterprises in Inner Mongolia (NJ-
2017-8) by using large data mining technology, a k-means clustering algorithm, an Apriori algorithm association rules, a correlation analysis algorithm, and made an empirical study with a case. The results show that the fault modes of data acquisition devices can be effectively analyzed by k-means algorithm, and the fault diagnosis and causes of data acquisition devices can effectively find out by Apriori algorithm of association rules and correlation between the characteristic parameters of data acquisition devices, which are consistent with the actual maintenance test results. Therefore, this method provides a reference for the operation, maintenance and control of data acquisition devices.
