AI Technical Summary

Technical Problem

Traditional elevator balance control methods are unable to adapt to the dynamically changing load distribution in the car in real time, resulting in unbalanced loading, increased vibration, increased energy consumption and equipment wear, and are unable to meet the requirements of modern elevators for operational quality and safety.

Method used

It adopts a load monitoring group, a liquid adjustable counterweight structure and a dynamic balance controller. The matrix-distributed load sensors monitor the pressure changes at the bottom of the car in real time, and the Y-axis and X-axis transverse movement components are used to adjust the position and weight of the counterweight liquid tank. The high-performance microprocessor is used to perform precise balance control.

Benefits of technology

It improves the stability of elevator operation, reduces vibration and noise, enhances safety, improves system reliability and energy saving, adapts to diverse load distribution, extends equipment service life and reduces maintenance costs.
