Noise reduction method and device for initial alarm data, equipment and storage medium

The invention provides an alarm data noise reduction method and device, equipment and a storage medium. The method comprises the steps that N pieces of obtained initial alarm data are input into a target prediction model, a prediction result of each piece of initial alarm data in the N pieces of initial alarm data is obtained, and the prediction results of the initial alarm data represent whether the initial alarm data are noise or not; the prediction results of the initial alarm data are input into a target alarm discrimination model, discrimination results corresponding to the prediction results of the initial alarm data are obtained, and the discrimination results corresponding to the prediction results of the initial alarm data represent the accuracy of the prediction results of the initial alarm data; and screening the N pieces of initial alarm data based on a discrimination result corresponding to the prediction result of each piece of initial alarm data, and triggering an alarm event under the conditio
