Stereo garage lifting vehicle carrying flat plate safety state monitoring and evaluating method

Abstract

The invention discloses a stereo garage lifting vehicle carrying flat plate safety state monitoring and evaluating method. A lifting vehicle carrying flat plate, steel wire ropes, a temperature self-compensation fiber bragg grating strain sensor, an optical fiber transmission line, a fiber bragg grating data acquisition unit and a stereo garage lifting vehicle carrying flat plate safety state evaluating unit are included. The temperature self-compensation fiber bragg grating strain sensor is mechanically and fixedly mounted on the four steel wire ropes of the lifting vehicle carrying flat plate to monitor the deformation condition of the steel wire ropes, according to deformation monitoring data of the steel wire ropes, the stereo garage lifting vehicle carrying flat plate safety state evaluating unit calculates the bearing load and the inclination degree of the lifting vehicle carrying flat plate, and according to the bearing load and the inclination degree of the flat plate, safety monitoring and early warning can be conducted on vehicle hanging collision or turnover accidents caused by the bearing capacity and inclination of the flat plate.

Description

technical field [0001] The invention belongs to the safety field of three-dimensional garage equipment, and in particular relates to a method for monitoring and evaluating the safety state of a three-dimensional garage lifting vehicle-carrying flat panel. Background technique [0002] With the development of the economy and the improvement of living standards, automobiles have become a means of transportation that people rely on in their lives. At the same time, with the sharp increase in the number of cars, the problem of static traffic has become very prominent, which has brought a series of illegal parking problems. In order to solve the problem of parking difficulties, three-dimensional garages began to enter the sight of urban planners. The three-dimensional garage maximizes land use in a limited construction area, greatly increases the number of parking vehicles, and alleviates the problem of difficult parking in prosperous areas to a certain extent. The three-dimens...

AI Technical Summary

Problems solved by technology

The three-dimensional garage is a special equipment. Although professional engineers will regularly overhaul the garage, the three-dimensional garage is frequently used. In the long-term operation process, its lifting system is the most prone to problems. The resulting rollover or hitch accidents often occur

The main reason for the overturning or hanging collision accident in the three-dimensional garage is the inclination of the lifting vehicle platform and the insufficient carrying capacity. The four steel wire ropes of the car platform are deformed unevenly or the bearing capacity is reduced

At present, the safety issues of the three-dimensional garage lifting system mainly focus on the maintenance and maintenance of the motor and chain, but there is no relevant report on the method of monitoring and evaluating the safety status of the lifting vehicle platform based on the force monitoring of the steel wire rope of the lifting system
