[0068] In step 340, a maintenance plan for the target equipment is obtained based on the target diagnosis score under the monitoring index and the comprehensive target diagnosis score.

[0069] In another embodiment, an indicator impact factor corresponding to each monitoring indicator may also be determined. The indicator impact factor corresponding to each monitoring indicator may be determined based on data. The indicator impact factor may be considered as the degree of influence of the monitoring indicator on the normal operation of the target device.

[0070] Furthermore, the indicator influencing factors and target diagnosis scores under each monitoring indicator can be weighted and summed to obtain a comprehensive target diagnosis score for the target device. Based on the target diagnosis score under the monitoring indicator and the comprehensive target diagnosis score, the maintenance plan for the target device is jointly determined. In this embodiment, the maintenance plan for the target device is jointly determined based on the overall (corresponding to the comprehensive target diagnosis score) and the local (the target diagnosis score under the monitoring indicator), which can improve the accuracy and rationality of the maintenance plan for the target device.

[0071] In another exemplary embodiment of the present invention, the processing module may obtain a maintenance plan for the target equipment based on the target diagnosis score under the monitoring index and the comprehensive target diagnosis score in the following manner: Calling a pre-trained maintenance plan generation model, wherein the maintenance plan generation model is used to obtain a maintenance plan for a corresponding target device based on a target diagnosis score and a comprehensive target diagnosis score; The target diagnostic score and the comprehensive target diagnostic score are input into the maintenance plan generation model to obtain the maintenance plan of the target equipment output by the maintenance plan model.
