Document Type and Number:
WIPO Patent Application WO/2023/098226
Kind Code:
A1
Abstract:
A drilling tool rotation speed measuring method, a device applying the method, a system and a storage medium. The method comprises: when a drilling tool rotation speed measuring system measures a rotation speed of a drilling tool, first determining a sampling period of the drilling tool, then collecting a plurality of first acceleration values of the drilling tool in the speed direction in a sampling period, and fitting the plurality of first acceleration values to obtain a fitting curve, determining whether the drilling tool is in the rotating posture or not by determining whether the fitting curve meets a sine curve change or not, if it is determined that the fitting curve meets the sine curve change, determining that the drilling tool is in the rotating posture, and at this time, collecting a centrifugal acceleration value of the drilling tool, and then determining the actual rotation speed of the drilling tool according to the centrifugal acceleration value. In this way, it can be effectively avoided that when the drilling tool is in the non-rotating posture, the abnormal drilling tool rotation speed is output, and the accuracy of the drilling tool rotation speed is guaranteed.
