Abstract

The invention relates to a Hall device-based motor speed measurement method and device, a readable storage medium and electric equipment, and the method comprises the steps: carrying out the AD sampling of an output signal of a Hall device in real time, so as to obtain a sampling signal, and enabling the Hall device to be used for detecting the rotating speed of a motor; converting the acquired sampling signal into a pulse signal; respectively calculating the period of each pulse signal to form a period sequence; and determining the rotating speed of the motor according to the periodic sequence. By means of the technical scheme, the noise reduction effect can be achieved, and the response time is shorter.

Description

technical field [0001] The invention relates to the field of motor speed measurement, in particular to a Hall device-based motor speed measurement method, device, readable storage medium and electric equipment. Background technique [0002] Hall devices have sensitive magnetic characteristics, small size, fast response speed, and low cost, so they are widely used in motor speed measurement. The Hall device is based on the principle of magnetoelectric conversion. When the motor rotates a circle, the Hall device senses the change of the magnetic field and outputs an electric pulse. By measuring the pulse period, the speed of the motor can be calculated. [0003] When using the Hall device to detect the motor speed, the commonly used algorithm is to set the IO pin interrupt, for example, set the rising edge interrupt, the interval time between two interrupts, which corresponds to the current pulse cycle, this method is used to measure a single motor The speed is simple and eff...
