Embodiment Construction

[0042] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0043] refer to figure 2 , the present invention proposes an anti-resonance method for an electric bed, which is applied to the above-mentioned electric bed controller 1, including:

[0044] S1. When driving the motor to rotate, continuously obtain the vibration information of the electric bed;

[0045] S2. According to the vibration information, determine whether the electric bed reaches the preset vibration condition;

[0046] S3. If the preset vibration condition is reached, adjust the rotational speed of the drive motor 3.

[0047] In the above step S1, when the driving motor 3 is in a rotating state, when the electric bed is controlled to adjust the backrest angle, the vibration information of the electric bed can be continuously obtained through the vibration sensor 2, and the vibration of the electric ...

Abstract

The invention discloses an electric bed and an anti-resonance method for the electric bed. The anti-resonance method for the electric bed includes the following steps: when the driving motor rotates, continuously obtain the vibration information of the electric bed; judge whether the electric bed has reached the preset value according to the vibration information the vibration condition; if the preset vibration condition is reached, the speed of the drive motor is adjusted according to the preset rule. The electric bed and the anti-resonance method of the electric bed in the present invention can judge whether to reach resonance by detecting the vibration of the electric bed, and can actively avoid by adjusting the speed of the driving motor to avoid the resonance of the electric bed, make the use of the electric bed more comfortable, and enhance user experience .

Description

technical field [0001] The invention relates to the field of motor control, in particular to an electric bed and an anti-resonance method for the electric bed. Background technique [0002] Electric beds are generally driven by electric push rods. When used in the bedroom, the noise of the motor machinery seriously affects the user's experience, especially when the motor rotates at a certain speed and causes the electric bed to resonate, it is not only noisy, but also affects the service life of the electric bed. The mechanical strength is adversely affected, and the controller of the push rod motor should avoid the motor working in or near this state. Electric beds are generally driven by electric push rods. When used in the bedroom, the noise of the motor machinery seriously affects the user's experience, especially when the motor rotates at a certain speed and causes the electric bed to resonate, it is not only noisy, but also affects the service life of the electric bed....
