Rotating speed determination method and device, electronic equipment and computer readable storage medium

Abstract

The invention provides a rotating speed determination method and device, electronic equipment and a computer readable storage medium. The method comprises the steps that a vibration signal set corresponding to a target rotating body is acquired; the vibration signal group comprises vibration signals at a plurality of target positions on the target rotating body; performing blind source separation on the vibration signal group to obtain a plurality of vibration source signals; determining a frequency conversion source signal from the plurality of vibration source signals, wherein the rotating frequency source signal is related to the rotating frequency of the target rotating body; and determining the rotating speed of the target rotating body according to the rotating frequency source signal. According to the rotating speed determination method, blind source separation is carried out on the collected vibration signal group of the target rotating body, so that noise components existing in a frequency domain close to the rotating frequency in the single-channel vibration signal can be well eliminated, and the rotating frequency source signal highly related to the rotating frequency of the target rotating body is obtained; therefore, the rotating speed result calculated by using the rotating frequency source signal subsequently 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...
