AI Technical Summary

Technical Problem

In existing elevator control systems, there are accuracy issues in the conversion between the height signal from the magnetic scale and the pulse signal from the encoder, which affects elevator leveling.

Method used

The elevator control method using a magnetic scale is as follows: the magnetic scale of the magnetic scale is parallel to the elevator's running direction, and the reading head is installed on the elevator. By controlling the elevator to run at a preset speed, the leveling position is obtained, the floor position and pulse height are determined, and the elevator operation is controlled based on the effective conditions of triggering leveling, upper and lower limit, and forced signals based on the position and height of the magnetic scale.

Benefits of technology

There is no need to convert the magnetic scale height signal into an encoder pulse signal, which effectively avoids the impact of conversion accuracy on elevator leveling and improves the leveling accuracy and operation control of the elevator.

Abstract

The embodiment of the application discloses an elevator control method and device based on a magnetic scale and a medium, and is used in the technical field of elevator control. The method comprises the following steps: controlling the elevator to run at a preset speed to obtain a plurality of leveling positions in the running direction of the elevator; determining the floor positions corresponding to the plurality of leveling positions, determining the magnetic scale height of each floor and the pulse height between adjacent floors based on the floor positions; determining the effective conditions of the leveling signal, the upper and lower limit signals and the upper and lower forced signals of the elevator through the position of the magnetic scale and the magnetic scale height; and controlling the running of the elevator within the corresponding pulse height based on the effective conditions of the leveling signal, the upper and lower limit signals and the upper and lower forced signals of the elevator, so that the height signal of the magnetic scale does not need to be converted into the pulse signal of the encoder, and the influence of the leveling of the elevator due to conversion accuracy is effectively avoided.
