Embodiment 1

[0059] like figure 1 As shown, in an embodiment of the multi-domain joint fault prediction method for heterogeneous equipment, the steps are:

[0060] S100. Obtain cross-domain historical data of the target device before the target time, and construct target data sequences corresponding to each domain.

[0061] The target device can be any device in the power system or other systems, and can also be an independently operated device. The target device can be a sensor, etc. In order to predict the possibility of failure of the target device at the target time, first Obtain the cross-domain historical data of the target device before the target moment, and construct the target data sequences corresponding to each domain. Specifically, each domain may include the time domain, frequency domain, time-frequency domain, and graphic domain. The acquired target device is in For the cross-domain historical data before the target moment, the construction of the target data sequence corre...

The invention can realize accurate equipment failure prediction.

Description

technical field [0001] The present invention relates to the technical field of terminal control, and in particular to a heterogeneous equipment multi-domain joint fault prediction method, device, terminal and storage medium. Background technique [0002] The power system covers a very wide range. In order to maintain the normal operation of the power system, multiple devices need to work together, and multiple devices need to collect massive data for analysis. When the equipment fails, the process data is incomplete or unreliable, which will affect the safe and stable operation of the entire system. At present, there is no method to predict the failure of the equipment in the system. [0003] Therefore, the prior art still needs to be improved and improved. Contents of the invention [0004] Aiming at the above-mentioned defects of the prior art, the present invention provides a heterogeneous equipment multi-domain joint fault prediction method, device, terminal and stora...
