Problems solved by technology

However, because the control system needs a certain process to build up enough torque to achieve torque balance, the same control strategy is used to control the start of the elevator under different load conditions in the prior art. The balance has been reached, but it still needs to wait for the control strategy to be executed before it can start running, so the waiting time will be longer, which will affect the operating efficiency; The state of torque balance is not reached, so the elevator will slip when it starts

Embodiment 1

[0043] Please refer to figure 1 , the present embodiment provides an elevator startup control method, comprising the following steps:

[0044] Step 101: Compensating the motor torque after the elevator brake is opened;

[0045] Step 102: Detect whether the motor torque of the elevator reaches the torque balance, and if so, end the compensation for the motor torque.

[0046] The moment balance establishment time of the elevator is different under different load conditions. Generally speaking, the greater the load of the elevator, the longer the establishment time of the moment balance. It takes a long time to establish torque balance during load. Therefore, if a control strategy is used to control the starting process of the elevator, sometimes the car will slip because the elevator torque has not been balanced, and sometimes because the motor torque has been balanced but still needs to be Wait until the control strategy is executed before it can start running. Among them, a...

Embodiment 2

[0060] The elevator includes at least a car, a guide system, a traction system, a weight balance system, and an electric drive system. Among them, the main function of the guiding system is to limit the freedom of movement of the car and the counterweight, so that the car and the counterweight can only move up and down along the guide rail. The main function of the traction system is to output and transmit power to make the elevator run. The traction system is mainly composed of traction machine, traction wire rope, guide wheel and anti-rope pulley. The main function of the weight balance system is to relatively balance the weight of the car. During the operation of the elevator, the weight difference between the car and the counterweight can be kept within the limit, so as to ensure the normal traction transmission of the elevator; the system is mainly composed of the counterweight and the weight Compensation device composition. The function of the electric drive system is ...

Abstract

The present invention relates to the technical field of elevator control, in particular to an elevator startup control method and system, wherein the method includes: compensating the motor torque after the elevator brake is opened; detecting whether the motor torque reaches torque balance, and exiting the torque compensation mode if so, After the motor torque compensation of the elevator control system is completed, the elevator acceleration and deceleration control mode is started to control the elevator operation. The elevator startup control method provided by this application uses the torque compensation mode to compensate the elevator torque when the elevator starts, so that the motor torque reaches balance as soon as possible, which ensures the stability of the elevator during operation, prevents the problem of slipping, and improves the comfort of the user At the same time, when it is detected that the motor torque reaches the torque balance, the compensation for the motor torque will be terminated immediately, and the acceleration and deceleration control mode will be used to control the elevator to immediately enter the acceleration and deceleration mode to start running, which improves the operating efficiency.

Description

technical field [0001] The invention relates to the technical field of elevator control, in particular to an elevator startup control method and system. Background technique [0002] When the elevator is started, due to the difference in weight between the elevator car side and the elevator counterweight side, at the moment when the elevator brake is opened, due to the weight difference, the elevator car will slide for a certain distance, which will cause the elevator to run comfortably. become worse and affect the riding experience. [0003] In order to solve the car slipping problem, the existing elevator control system generally adds an analog weighing device. Before the elevator runs, the weight of the car is measured by the load cell, and then an initial torque is output through a series of parameters. Torque is applied to the motor before the brake is opened in order to overcome the effect of rolling. However, in addition to increasing the cost of the system, this so...
