Abstract

In order to improve the accuracy and speed of fault data acquisition of fluid power control system, this paper designs an automatic fault diagnosis method of fluid power control system based on English translation speech recognition. Firstly, the SDG model of the fluid dynamic control system is established, and the fault link is obtained and determined. Then the correlation dimension of data in fluid mechanics calculation is analyzed, and the fault data location is realized. On this basis, the fault classification model of the hydraulic power control system is established, and the automatic fault diagnosis of the hydraulic power control system is completed. Experiments show that the new fault diagnosis method can effectively improve the accuracy and speed of fault data acquisition of fluid power control system, the highest accuracy can reach 89.92%, the fastest speed is 11s, and improve the reliability of fault diagnosis results.
水动力控制系统故障的自动诊断方法
为了提高液压控制系统故障数据采集的准确性和速度,本文设计了一种基于英译语音识别的液压控制系统自动故障诊断方法。首先,建立了流体动力学控制系统的SDG模型,得到并确定了故障环节。然后分析了流体力学计算中数据的相关维数,实现了故障数据的定位。在此基础上,建立了液压动力控制系统的故障分类模型,完成了液压动力系统的故障自动诊断。实验表明,新的故障诊断方法可以有效地提高流体动力控制系统故障数据采集的准确性和速度,最高准确率可达89.92%,最快速度可达11s,提高了故障诊断结果的可靠性。
