Embodiment Construction

[0019] Such as Figure 1 to Figure 3 As shown, a method for automatically adjusting the starting compensation torque of an elevator according to the present invention is based on an elevator system provided with a weighing device. The elevator system mainly includes a power supply 1, a motor drive device 2, a motor 3, a controller 4, Weighing device 5, car 6 and counterweight 7. Wherein, the weighing device 5 adopts an eddy current sensor and is installed on the car 6 to detect the load of the car in real time and output the weighing data to the control board of the motor drive device 2 . The motor drive device 2 is mainly used to receive the control signal output by the controller 4 and the weighing data output by the weighing device 5, and drive the motor 3 to generate the starting compensation torque according to the starting compensation data provided by the controller.

Abstract

The invention discloses a method for adjusting the starting compensating moment of an elevator automatically. The method for adjusting the starting compensating moment of the elevator automatically comprises the following steps that A, a weighing self-learning condition is set, the operating state of the elevator is detected in real time through a controller of an elevator system, and when the operating state of the elevator meets the weighing self-learning condition, the weighing self-learning work mode is started; B, in the weighing self-learning work mode, when the elevator reaches each weighing self-learning storey, a weighing device detects the no-load weight of the weighing self-learning storey and outputs no-load weight data to the controller of the elevator system; C, the weighing offset is worked out through the controller of the elevator system according to the no-load weighing data; and D each time the elevator starts, the starting compensating moment is re-calculated by the controller of the elevator system according to the current load data and the weighing offset output by the weighing device, the starting compensating moment data are output to a motor driving device of the elevator system, and the motor driving device drives a motor to generate the starting compensating moment according to the starting compensating moment data.

Description

technical field [0001] The invention belongs to the technical field of elevator control, and in particular relates to a method for automatically adjusting the starting compensation torque of an elevator. Background technique [0002] At present, for elevators equipped with weighing devices, the starting compensation torque is mainly carried out in the following way: when the elevator starts, the weighing device detects the load of the elevator car, generates weighing data and feeds back to the controller of the elevator system , the controller sends a control signal according to the weighing data and the current elevator running state to control the motor through the motor drive device to generate a corresponding starting compensation torque. Although this processing method is simple in structure and low in cost, it can meet the operation requirements of most elevators. In addition, the elevator compensation chain and compensation cable will also affect the effect of starti...
