AI Technical Summary

Technical Problem

The current loop coefficient of the existing elevator controller is fixed, which cannot maintain the comfort of the elevator under different operating conditions. This results in the comfort level being better on the bottom floor but worse on the top floor, or the comfort level being better when going downhill without load but worse when going uphill without load.

Method used

The current loop coefficient is dynamically adjusted based on the current operating status of the elevator, including factors such as car height, driving or braking status, and upward or downward movement. The appropriate current loop coefficient is calculated by selecting the corresponding current loop formula for control.

Benefits of technology

By dynamically adjusting the current loop coefficient, the elevator can be guaranteed to operate stably under various conditions, thereby improving the elevator's comfort.

Abstract

The application discloses a control method and device of elevator operation and a medium, and is applied to the technical field of elevators. The method acquires the current operation state of the elevator in the process of elevator operation, and then determines the current loop coefficient for controlling the elevator according to the current operation state of the elevator. If the current operation state of the elevator represents that the load of the elevator is larger, the current loop coefficient is larger; if the current operation state of the elevator represents that the load of the elevator is smaller, the current loop coefficient is smaller; finally, the elevator is controlled according to the determined current loop coefficient. In the use scene of the elevator, when the load is larger, a stronger current loop is needed, that is, the current loop coefficient is larger, when the load is smaller, a weaker current loop is needed, that is, the current loop coefficient is smaller, so as to ensure the stability of the elevator operation. The scheme selects the current loop coefficient with appropriate size according to the current operation state of the elevator, so that the elevator can stably operate in various states, and the comfort of the elevator is improved.
