Description

technical field [0001] The invention relates to the technical field of filters, in particular to a method for generating filter parameters, a vibration sensing module, a computer device and a storage medium. Background technique [0002] The response frequency and error of the vibration sensor affect the application effect of the vibration sensor. For example, if the vibration sensor used in the vibration measurement process, if its response frequency can reach 1kHz, then the vibration signal measured by the vibration sensor can be analyzed to "unbalance", "misalignment", "shaft bending", " Belt looseness”, “foundation looseness” and “late bearing damage” and other faults; if the response frequency can reach 5kHz, then the vibration signal measured by the vibration sensor can also analyze “bearing mid-term fault”, “poor lubrication”, Faults such as "reducer gear wear", "cavitation", "motor stator fault" and "motor rotor eccentricity"; if the response frequency can reach 20k...
