Abstract

The present application provides a method, device, electronic equipment, and computer-readable storage medium for determining a rotational speed, wherein the method includes: acquiring a vibration signal group corresponding to a target rotating body; the vibration signal group includes vibrations at multiple target positions on the target rotating body signal; carry out blind source separation on the vibration signal group to obtain multiple vibration source signals; determine the frequency conversion source signal from multiple vibration source signals; the frequency conversion source signal is related to the conversion frequency of the target rotating body; according to the frequency conversion source signal, Determine the rotational speed of the target rotating body. The rotation speed determination method provided by this application can eliminate the noise components existing in the frequency domain close to the rotation frequency in the single-channel vibration signal by performing blind source separation on the collected vibration signal group of the target rotating body, and obtain the rotation speed of the target rotating body. The conversion frequency source signal with high frequency correlation, so the speed result calculated by using the conversion frequency source signal is more accurate.

Description

technical field [0001] The embodiments of the present application relate to the technical field of rotational speed measurement, and in particular to a rotational speed determination method, device, electronic equipment, and computer-readable storage medium. Background technique [0002] Rotating equipment has been widely used in various industries. Common rotating equipment includes generators, steam turbines, aircraft engines, water pumps, fans, etc. In order to ensure the safe and normal operation of these rotating bodies, it is necessary to monitor the rotating speed of the rotating bodies. In the prior art, the rotational speed of the rotating body can be measured with a professional rotational speed measuring device, but the cost of the rotational speed measuring device is relatively high, and it is also very difficult to install a rotational speed measuring device on an already installed rotating body. [0003] Based on this, the prior art proposes a variety of techn...
