Problems solved by technology

[0002] At present, the main methods for calculating the running height of the elevator are: installing a rotary encoder on the motor and reading the encoded pulse data to calculate the height, or installing Encoding card and card reader to calculate the height; the shortcomings of the current existing technology are mainly complicated installation and high cost, and are not suitable for application in the elevator after-installation monitoring system

Abstract

The invention relates to the technical field of elevator monitoring, in particular to a method for measuring the running height of an elevator. The method comprises the following steps of acquiring an acceleration signal in a vertical running direction by an acceleration sensor; performing data preprocessing on the acquired acceleration signal; calculating a speed v according to the acceleration obtained after data preprocessing; integrating the elevator running time through the obtained speed v to obtain an elevator running height h; forming a floor height table for the specific height of an on-site floor; when an elevator stops, comparing the running height h with the floor height table to inquire the floor number closest to the running height h; and finally, calibrating the running height h through a height calibration switch with the height of the floor number in the floor height table to finish the measurement of the running height of the elevator, determination of the floor number and calibration of the running height. According to the method, only the acceleration sensor and the height calibration switch need to be installed, and the acceleration sensor is installed on the elevator car roof, so that installation is simple and cost is low.

Description

【Technical field】 [0001] The invention relates to the technical field of elevator monitoring, in particular to a method for measuring the running height of an elevator. 【Background technique】 [0002] At present, the methods for calculating the running height of the elevator mainly include: installing a rotary encoder on the motor and reading the encoded pulse data to calculate the height, or installing an encoding card and a card reader on the hoistway and car top to calculate the height; The main reason is that the installation is complicated and the cost is high, so it is not suitable for application in the elevator after-installation monitoring system. 【Content of invention】 [0003] The purpose of the present invention is to provide a cheap and easy-to-install method to calculate the running height of an elevator. [0004] The present invention is realized by the following technical solutions: [0005] A method for measuring the running height of an elevator, compri...
