Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0034] see figure 1 As shown, it is a schematic flow chart of an elevator vibration reduction control method according to an embodiment of the present invention. The elevator vibration reduction control method in this embodiment comprises the following steps:

[0035] Step S110: when the elevator car is running, acquire the acceleration signal of the car in the vibration direction;

[0036] Step S120: Proportional-integral adjustment is performed on the acceleration signal to obtain a current adjustment signal of the servo motor;

[0037] In this step, through proport...

Abstract

The invention relates to an elevator vibration reduction control method, system and device. When an elevator car runs, an acceleration signal of the elevator car in a vibration direction is acquired,the acceleration signal is converted into a current adjusting signal of a servo motor, and then the current adjusting signal is used for driving the servo motor to push a guide shoe roller on the elevator car to move in the vibration direction. Since the guide shoe roller is mounted on an elevator, rolls on fixed guide rails, and is pushed to move in the vibration direction when the elevator vibrates, the elevator car can be prevented from further moving in the vibration direction, then the vibration of the elevator car is reduced, and the running stability of the elevator is guaranteed.

Description

technical field [0001] The invention relates to the technical field of elevator vibration reduction, in particular to an elevator vibration reduction control method, system and device. Background technique [0002] With the rapid development of science and technology and economy in the world, the number of high-rise buildings continues to increase, and elevators have become an indispensable means of vertical transportation in modern life. In order to save the time of transporting passengers and improve the operating efficiency of elevators, the speed of elevators continues to increase. At present, the maximum operating speed of the elevator has reached 21m / s (75.6Km / h), which is equivalent to a "vertical moving car". Since the elevator car runs in the narrow and long shaft, the speed of the car increases, which will inevitably increase the vibration and seriously affect the stability and safety of the elevator. [0003] The deformation of elevator guide rails and the distur...
