[CN 202011306654.9] A Preprocessing Method for Vibration Monitoring Data of Mechanical Press
[CN 202011306654.9] Title of a Preprocessing Method for Vibration Monitoring Data of Mechanical Press: Application Number of a Preprocessing Method for Vibration Monitoring Data of Mechanical Press: CN 202011306654.9 Applicant: Xi 'an Yilian Information Technology Co., Ltd. Application Date: 2020-11-18 Patent Type: Invention Application for a Preprocessing Method for Vibration Monitoring Data of Mechanical Press, including the following steps: Step 1, Preprocessing Vibration Signals Collected from Vibration Monitoring of Mechanical Press, cleaning the abnormal vibration signal; Step 2, calculating the local peak ratio of the vibration signal; Step 3, judging whether the vibration signal is affected by the stamping according to whether the local peak ratio calculated in Step 2 is greater than the set abnormal threshold. The invention pre-processes the vibration monitoring data of the mechanical press, calculates the local peak ratio characteristics of the vibration signal, and determines whether the vibration signal is an abnormal signal affected by stamping according to whether the local peak ratio exceeds the abnormal threshold. The method of the invention is simple and efficient, does not need to set the algorithm parameters, and ensures that the technology has a very good general ability.
