Vibration alarm method, storage medium and electronic equipment

Abstract

The embodiment of the invention provides a vibration alarm method, a storage medium and electronic equipment, and the method comprises the steps: determining a corresponding equivalent value accordingto the vibration acceleration data of a measurement point, and determining a dynamic safety threshold value according to the equivalent values accumulated one by one; determining a vibration acceleration over-limit probability value according to the maximum vibration acceleration data of the measuring point, and further determining an over-limit probability development trend coefficient accordingto the vibration acceleration over-limit probability value; and determining an alarm state according to a vibration acceleration equivalent value of the measuring point, a dynamic threshold operationresult, an effective value development trend coefficient and an over-limit probability development trend coefficient. The vibration alarm method provided by the embodiment of the invention solves theproblem of false alarm or untimely alarm easily caused by using the design allowable value as the alarm threshold.

Description

technical field [0001] The invention relates to the field of safety monitoring, in particular to a vibration alarm method, a storage medium and electronic equipment. Background technique [0002] The vibration safety assessment of wind turbine tower is a key issue in the operation safety monitoring of wind turbine tower. The existing wind turbine tower vibration safety assessment method is mainly based on comparing the vibration monitoring parameter value with the design allowable value to roughly obtain the tower vibration safety level. Such an evaluation method has a relatively large error in the evaluation result due to the following reasons: first, the safety allowable value given by the design is mainly calculated based on simulation technology, and the error is relatively large; second, although the structural design of the same type of tower is consistent, However, due to construction errors, foundation soil layers, and material properties, it is difficult to ensure ...
