Elevator car load device correction method

Abstract

The invention discloses an elevator car load device correction method which includes the steps: recording the weight of an elevator counter-weight and car empty weight; acquiring the weight corresponding to output torque; comparing the sum of the car empty weight and the weight corresponding to the output torque with the weight of the elevator counter-weight to obtain car internal load calculationweight; acquiring car internal load weighing weight; judging whether the car internal load calculation weight and the car internal load weighing weight have deviation or not; comparing the car internal load calculation weight with the car internal load weighing weight to obtain correction coefficient if the car internal load calculation weight and the car internal load weighing weight have deviation; compensating the correction coefficient into a weighing device calculation module to correct an elevator weighing device. The elevator car load device correction method is used for correcting thedeviation of the elevator weighing device, elevator weighing accuracy and elevator running comfort are improved, and the elevator car load device correction method has good economic benefits.

Description

technical field [0001] The invention relates to the field of elevator control, in particular to a method for correcting a load-carrying device of an elevator car. Background technique [0002] In the existing elevator system, the load in the elevator car is mainly completed by a weighing device. The weighing device is generally on the car or the rope end, and rubber or springs and other deformable objects are installed. When the load of the car is different, the corresponding deformation will occur, and the corresponding analog signal will be output, and then the processor of the elevator system will collect the analog signal and calculate the weight of the load in the car. These objects for estimating the weight and load value in the car are easily affected by thermal expansion and contraction, or their own aging phenomena, which will reduce the accuracy of the load value in the car. The weighing and starting of the elevator mainly depends on the accuracy of the weighing d...

These objects that estimate the weight and load value in the car are easily affected by thermal expansion and contraction, or their own aging phenomena, which will reduce the accuracy of the load value in the car

The weighing and starting of the elevator mainly depends on the accuracy of the weighing device. When the calculated value deviates, it will cause problems such as starting shock, the operating comfort of the system will deteriorate, and it needs to be restarted every few months. Weighing machines are used to correct weighing deviations, increasing maintenance workload and maintenance costs
