Problems solved by technology

There are currently two methods for detecting the speed of DC motors. One is to detect the speed of the motor through external devices, such as speed sensors and optical sensors. This method is prone to failure, failure, heat generation and low efficiency during long-term use.
Another method is to extract the voltage or current signal, and then use signal processing technology to extract the harmonics of the speed. This method is too dependent on the specificity of the signal itself. When the signal is disturbed, the collected signal will be distorted, resulting in a large error
Moreover, the calculation process of extracting the harmonics of the speed through signal processing technology is cumbersome, with a large amount of calculation and low calculation efficiency

Abstract

The invention discloses a method, device, storage medium and electronic equipment for detecting the rotational speed of a DC motor, aiming at calculating the rotational speed of the DC motor according to the voltage signal of the DC motor without external hardware detection. The implementation cost of the embodiment of the present invention is low, the amount of calculation is small, the calculation is real-time, and the calculation process is low in cost and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method, device, storage medium and electronic equipment for detecting the rotation speed of a DC motor. Background technique [0002] In the transmission system, it is usually necessary to detect and control the speed of the motor to judge the performance of the motor and improve the accuracy of the system. There are currently two methods for detecting the speed of DC motors. One is to detect the speed of the motor through external devices, such as speed sensors and optical sensors. This method is prone to failure, failure, heat generation and low efficiency during long-term use. Another method is to extract the voltage or current signal, and then use signal processing technology to extract the harmonics of the speed. This method is too dependent on the specificity of the signal itself. When the signal is disturbed, the collected signal will be distorted, resulting in large e...
