Embodiment Construction
[0041] The present invention will be described below in conjunction with the accompanying drawings and specific embodiments. Unless otherwise specified, all are conventional methods.
[0042] Such as figure 1 and figure 2 As shown, a method for fault diagnosis of mechanical equipment based on deep learning includes the following steps:
[0043] Step S1: Collect and preprocess data from the main data source and secondary data source of mechanical equipment to obtain a data set, wherein the main data source is sensor monitoring data, and the secondary data source is operating status data and historical inspection data;
[0044] The sensor monitoring data is the measuring point information collected by the sensor in real time, which belongs to the time series data, so there is correlation in the time series. The selection of the fault diagnosis method of the present invention fully takes into account the time series correlation. First, obtain the long-term vibration signal of t...
