Problems solved by technology

However, this method has high requirements for the real-time and accuracy of acceleration signal acquisition, and it is prone to wrong actions, which affects the comfort of the elevator ride. At the same time, because the servo motor is dynamically adjusted in real time according to the collected acceleration signal, there is servo motor overshoot. Possibility of damaging the guide shoe

Embodiment Construction

[0021] The specific implementation of the elevator vibration reduction method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] Such as figure 1 Shown, a kind of elevator damping method comprises steps:

[0023] S110. Obtain the current actual elevator car load and the current elevator floor position;

[0024] S120. Select a car load that is different from the actual car load of the elevator within a preset range from the recorded car loads, and use the selected car load as the current car load;

[0025] S130, according to the corresponding relationship between the recorded car load, the elevator floor position and the rotational displacement of the servo motor, determine the rotational displacement of the servo motor corresponding to the current car load and the current elevator floor position;

[0026] S140. Adjust the servo motor installed on the guide shoe according to the determined amount of rotational di...

Abstract

The invention discloses an elevator vibration attenuation method and device. The elevator vibration attenuation method comprises the steps that the current actual elevator car load and the current elevator floor position are obtained; a car load is selected from recorded car loads, wherein the difference between the selected car load and the actual elevator car load is within the preset range, and the selected car load is used as the current car load; according to the corresponding relation among recorded car loads, the elevator floor position and servo motor rotation displacement, the servo motor rotation displacement corresponding to the current car load and the current elevator floor position is determined; according to the determined rotation displacement, a servo motor installed on a guide shoe is adjusted. According to the elevator vibration attenuation method and device, the requirement for acceleration signal collection real-time performance and accuracy is lowered, the servo motor adjusting accuracy and the elevator riding comfort level are improved, and meanwhile the problem that the guide shoe is damaged caused by over adjustment of the servo motor is avoided due to the fact that the rotation displacement of the servo motor is a known and determined adjustment variable.

Description

technical field [0001] The invention relates to the technical field of elevator vibration reduction, in particular to an elevator vibration reduction method and an elevator vibration reduction device. Background technique [0002] With the emergence of high-rise and super high-rise buildings in cities, the speed of elevators is also increasing. The increase of elevator speed makes the vibration in the horizontal direction of the elevator more and more serious, seriously affecting the comfort of the elevator and the service life of the elevator, and the comfort of the elevator is also an important indicator of the quality of the elevator. [0003] At present, there are many technologies and methods for active vibration reduction of elevators, and active vibration reduction guide shoes are one of them. In this method, the acceleration signal of the car is collected by the acceleration acquisition board, and the controller determines the control signal for slowing down the vib...
