时间序列符号化在矿用提升机故障诊断中的应用研究

为了能够对矿用提升机故障进行准确的诊断，采用时间序列符号法，分析了矿用提升机常见的故障和提升机的系统组成，然后构建了基于时间序列符号法的提升机故障诊断框架，并将该方法应用到试验研究中。研究得出，通过处理和分析提升机运行状态的时序数据，验证了时间序列符号法在矿用提升机故障诊断中的有效性和可行性，实现了矿用提升机的多故障诊断。

Application research of time series symbolization in fault diagnosis of mining hoist

In order to accurately diagnose the mine hoist fault，the time series symbol method was used to analyze the common faults of the mine hoist and the system composition of the hoist，and then the hoist fault diagnosis framework based on the time series symbol method was constructed.The method was applied to the experimental study.The study shows that by processing and analyzing the time series data of the operating state of the hoist，the validity and feasibility of the time series symbol method in the fault diagnosis of the mine hoist are verified and the multi-fault diagnosis of the mine hoist is realized.
