Problems solved by technology

[0002] At present, the mainstream elevator control system is basically closed-loop vector control, and the premise of realizing closed-loop control is to install an encoder on the motor shaft. Achieving low-cost operation requires normal operation control without an encoder
However, for the current elevator control system without an encoder, there are the following disadvantages: because there is no encoder for position positioning, the efficiency of the elevator running curve is low, or the elevator leveling debugging is troublesome, time-consuming and laborious

Abstract

The invention relates to a lift control method and system. The lift control method comprises the following steps of 1, recording deceleration distances from S1 to Sn of a lift between every two adjacent floors from the time point when the lift decelerates to the time point when the lift runs to leveling positions; 2, calculating deceleration speeds from A1 to An of the lift between every two adjacent floors according to the running speed of the lift and the crawling speed of the lift; and 3, adjusting the deceleration speed A1 according to the deceleration distance S1, the running speed of the lift and the crawling speed of the lift to control the lift to be leveled between the top floor and the second top floor, and then sequentially adjusting the deceleration speeds from A2 to An according to the deceleration distances from S2 to Sn, the running speed of the lift and the crawling speed of the lift to control the lift to be leveled between every two adjacent floors until the leveling of the lift between every two adjacent floors is completed. According to the lift control method and system, the leveling debugging of the lift can be completed only according to the deceleration distances, the running speed of the lift and the crawling speed of the lift, the operation is convenient, and no encoder for positioning is needed.

Description

technical field [0001] The present invention relates to elevator control technology, in particular to an elevator control method and system with no encoder and simple leveling adjustment. Background technique [0002] The current mainstream elevator control systems are basically closed-loop vector control, and the premise of realizing closed-loop control is to install an encoder on the motor shaft. Achieving low-cost operation requires normal operation control without an encoder. However, for the current elevator control system without encoder, it has the following disadvantages: because there is no encoder for position positioning, the efficiency of the elevator running curve is low, or the elevator leveling debugging is troublesome, time-consuming and labor-intensive. SUMMARY OF THE INVENTION [0003] Based on this, it is necessary to provide an elevator control method and system that requires no encoder and is simple to adjust for leveling. [0004] An elevator contro...
