Abstract

The invention provides a method for measuring the rotation speed based on fusion of several kinds of characteristic data. The method comprises: collecting more than one kind of motor rotation speed characteristic data; processing the rotation speed characteristic data by using an autocorrelation function to obtain a periodic signal of a data waveform; carrying out algorithm transformation to obtain a frequency corresponding to the data waveform; and inputting the corresponding frequency into a data fusion prediction model for fusion to obtain a rotation speed of the motor. In addition, the invention also provides an apparatus for measuring the rotation speed based on fusion of several kinds of characteristic data. The apparatus includes a sensor module, a display module and a main controlmodule. According to the invention, the rotation speed is calculated based on fusion of several kinds of characteristic data; the stability and accuracy of the rotation speed measurement are improved;and a problem of the mounting trouble of the existing device is solved.

Description

technical field

[0001] The invention relates to the field of mechanical rotational speed measurement, in particular to a rotational speed measurement method and device integrating multiple characteristic data. Background technique

[0002] Currently on the market, most motor speeds are obtained by measuring one data characteristic. However, only measuring one data characteristic has the problem of low accuracy. After the data characteristic is disturbed, the desired result cannot be obtained; in addition, the existing Most rotational speed measurement devices need to install sensing components on the motor or the rotating shaft. Accurate measurement of the rotational speed can only be achieved with the sensing components. The installation process is cumbersome and has certain requirements on the rotating shaft, making it difficult to achieve convenient measurement. Contents of the invention

[0003] The purpose of the present invention is to provide a rotational speed meas...
