Method for controlling elevator leveling and elevator capable of realizing leveling control by applying method

Abstract

The invention provides a method for controlling elevator leveling and an elevator capable of realizing leveling control by applying the method. The method comprises the following steps of receiving a target floor signal that a floor needs to be reached; reading the height mark of a position where a lift car is positioned; according to the target floor signal, when the elevator is on the target floor to achieve leveling, the preset height mark corresponding to the floor leveling signal mark of the target floor is acquired; the operation height required by the lift car is outputted, and the lift car is controlled to start operation; the height mark when the lift car is in operation is read, and when the floor leveling signal mark signal of the target floor is obtained, the lift car stops operation; the actual height mark corresponding to the floor leveling signal mark of the target floor is obtained, and the height difference between the corresponding actual height mark of the lift car and the preset height mark is analyzed; and if the height difference is within the prestored error interval, elevator leveling control is completed. The method can relatively accurately control elevator leveling.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator leveling control method and an elevator using the method for leveling control. Background technique [0002] Nowadays, there are elevators in almost all high-rise buildings. How to make the elevator realize leveling safely and reliably, that is to say, make the horizontal sill of the entrance and exit of the elevator car reach the same height as the horizontal sill of the entrance and exit of the target floor, has received the general attention of various elevator manufacturers. [0003] In the prior art, a height encoder is generally installed on the hoist of the elevator car to detect the height of the elevator, and floor induction switches such as magnetic switches and electric switches are added on the side of the elevator car to determine the leveling signal. [0004] During operation, the interior of the elevator leveling control system stores the correspondi...

Problems solved by technology

[0007] Furthermore, in the actual use of the elevator, if the height of the elevator shaft changes due to the building itself, the corresponding height of each floor in the shaft will change, and the elevator leveling control system cannot pre-store the The corresponding height of each floor in the system corresponds to the actual height of the floor, which may easily cause the elevator to fail to level the floor correctly

If this phenomenon occurs, it is necessary to re-measure the corresponding height of each floor and adjust the elevator leveling control system. This adjustment method is costly and time-consuming
