A data-driven elevator traction force monitoring method and monitoring device

Abstract

The invention discloses an elevator traction force monitoring method based on data driving and a monitoring device of the elevator traction force monitoring method based on data driving. The elevatortraction force monitoring method comprises the steps of acquiring a change signal of the acceleration change over time of an elevator car and station positions of the elevator car; acquiring running time of the elevator car at different stations; comparing the longitudinal data and the transverse data respectively; and analyzing and determining whether the traction force is degraded or not. The monitoring device is characterized in that a flat-layer sensor is in signal connection with a controller and is used for collecting the position signals of the stations of the elevator car; the flat-layer sensor is fixed on the top of the elevator car; and a base station baffle is fixed to a base station in a well and is used for confirming the position of the base station. The monitoring method andthe monitoring device have the beneficial effects that the monitoring device is arranged at the top of the elevator car and in the well, and is convenient and rapid to install; the monitoring deviceis independent of elevator autonomous monitoring and is not limited by the models of elevators, so that the universality is high; and the big data analysis method is adopted to compare the longitudinal data and the transverse data between historical data of test results, and the big data management provides reference for monitoring traction performance and guiding prevention and maintenance of a traction wheel / steel wire ropes, so that the labor maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of elevator inspection and detection; in particular, it relates to a data-driven elevator traction monitoring method and a monitoring device. Background technique [0002] With the rapid development of my country's economic construction and the rapid construction of high-rise buildings, elevators have become a convenient vertical means of transportation for the people. They play an irreplaceable role in daily life, and their operational reliability is increasingly valued. As one of the important parameters of elevator design, traction force is also an important factor to consider the safety, comfort and stability of elevators. As the elevator is used for a long time, factors such as excessive lubrication and wear of the wire rope and excessive wear of the traction sheave groove will cause the friction coefficient to become smaller, which will lead to insufficient traction. When the traction force is insuffic...

Problems solved by technology

[0007] 1. In the detection method, the distance difference between the absolute position of the elevator car and the actual position of the leveling floor is calculated, which is affected by the braking force of the elevator and there is a deviation;

[0008] 2. The requirement for the leveling position in the detection method is not limited to the floor closest to the elevator stop position, and the detection results are different due to the different leveling positions
