An Evaluation Method for Elevator Operation Status Based on Detection Data

To effectively evaluate the status of elevators, an evaluation method for elevator operation status based on detection data is proposed. An elevator operation status evaluation index system is created in conjunction with elevator inspection and testing requirements. The correlation degree of the influential parameters for the elevator operation status is calculated based on the gray correlation method and hierarchical analysis method. And then the elevator operation status is evaluated by the correlation. Taking three elevators in a certain building as an example to evaluate the operation status, the influence parameter matrix for the evaluation of elevator operation status is constructed based on the detection data. The weight and correlation degree of the influencing parameters are calculated, and the evaluation of the elevator operation status is achieved. The result was "good", which is consistent with the actual inspection and detection.
