Air valve angle control method and device, air valve and storage medium

Abstract

The embodiment of the invention discloses an air valve angle control method and device, an air valve and a storage medium. The control method comprises the steps that a motor of the air valve is controlled to rotate to drive a valve plate of the air valve to rotate from a first opening angle to a target opening angle; wherein a magnet is fixed on a rotating shaft of the motor, and the magnet and the motor synchronously rotate; a Hall sensor is further arranged on the motor; collecting the number of pulse signals generated by the Hall sensor in the rotation process of the magnet; determining the current rotation cycle number of the motor according to the number of pulse signals; and the motor is continuously controlled to rotate until the current rotation cycle number of the motor reaches the target rotation cycle number corresponding to the target opening angle of the valve plate. According to the invention, the current rotation number of the motor is determined by detecting the change of the magnetic field based on the Hall sensor, and when the current rotation number is equal to the target rotation number, the valve plate rotates to the target opening angle, so that the rotation angle of the air valve plate can be accurately controlled, the air volume of each user terminal is accurately distributed, and the use requirements of users are met.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of damper control, and in particular, to a damper angle control method, a control device, a damper and a storage medium. Background technique [0002] The current use of external exhaust smoke in the kitchen's range hood has a great impact on the environment, so several brand companies in the industry have launched a central range hood to uniformly absorb the fume from the public flue, filter, purify and then discharge it. The air volume of the top host needs to be adjusted in linkage with the air valves on each floor, so as to control the air volume of the oil fume of each user terminal, so that each user terminal can evenly distribute the air volume power of the host. [0003] The existing air valve controls the opening angle according to the rotation time, but due to the difference in the speed of each air valve motor, the change of the ambient temperature, and the error of the a...

Problems solved by technology

[0003] Existing air valves control the opening angle according to the rotation time, but due to the different factors such as the speed error of each air valve motor, the change of the operating environment temperature, and the error of the oil resistance of the air valve, the control accuracy of the air valve angle is not enough, and it is difficult to accurately control its position. The required air valve angle value, the air volume and power distribution effect between each user terminal is poor
