Abstract
The invention discloses an elevator component performance model construction method. The method comprises the steps of determining performance characterization indexes of elevator parts, a calculationmethod of the performance characterization indexes and variables required for calculating the performance characterization indexes; determining all influence factors related to the performance of theelevator parts; obtaining influence factor values and variable values of the elevator parts when the elevator parts are in the influence factor values; calculating a characterization index value by using the variable value; according to the corresponding relation between the variable values and the influence factor values, utilizing the characterization index values and the influence factor values corresponding to the variable values corresponding to the characterization index values to form model data pairs related to the performance of the elevator parts; and utilizing the model data pair to construct an elevator part performance model. According to the method, the relation model between the performance characterization indexes and the influence factors is constructed by utilizing the real data (influence factor values and variable values) of elevator operation, so that the actual performance conditions of elevator parts are accurately mastered, and reference is provided for design,operation quality and maintenance of elevators.
Description
technical field [0001] The present invention relates to the field of elevators, and specifically belongs to a method for constructing an elevator component performance model. The elevator component performance model is used to describe the influence factors related to the elevator component performance have on the performance of the elevator component, wherein the elevator component can be It is a single elevator part that can independently realize a certain function, or it can be a component that can realize a certain function and is composed of multiple elevator parts. Background technique [0002] There are many components in the elevator, and each elevator component has a certain function. The performance of the elevator components will directly affect the overall performance of the elevator. Therefore, in order to be able to accurately evaluate the overall performance of the elevator in use, it is necessary to grasp the performance of the elevator components in a timely...
