Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] like Figure 1-3 As shown, a technology that uses high-speed cameras to quickly detect the safety performance of curtain walls includes the following specific steps:

[0026] 1) Determine the parameters of the panel panels used in the curtain wall 1 to be tested, and determine the reference frequency range of the panels according to the basic database of the vibration frequency of the curtain wall 1 compiled by the laboratory; the basic database establishes basic models according to different types of curtain walls, Calculate the theoretical frequency, detect the basic vibration frequency and frequency range of different types of curtain wall 1, correct the theoretical model, and finally obtain the basic database of curtain wall 1.

[0027] 2) A high-speed camera 2 is used for the curtain wall 1 on site, and the image speckle recognitio...

Abstract

The invention discloses a curtain wall safety performance rapid detection method based on an image technology. The method comprises four contents: using an early-stage data acquisition and later-stagevibration data processing method using a high-speed camera; marking points marked on the surface of a curtain wall by an unmanned aerial vehicle; a vibration reaction after the unmanned aerial vehicle jets shots to simulate external knocking; and a safety evaluation method. The method has the advantages of simplicity, convenience, no damage and the like, and a more reliable curtain wall detectionmode is provided for the work of the detection industry so as to ensure the safety performance of the curtain wall in the service process. The method is mainly used for quickly detecting the buildingcurtain wall and evaluating the safety performance of the curtain wall in the service period.

Description

technical field [0001] The technical field of the present invention is building safety detection, specifically a technology for quickly detecting the safety performance of a curtain wall by using a high-speed camera, which is applied to the fields of construction and detection. Background technique [0002] The traditional curtain wall inspection mainly makes some requirements for the inspection of the joints and connections of the curtain wall and the installation inspection, so that it can be controlled in advance before installation, but there are still many shortcomings. [0003] 1. The traditional curtain wall inspection technology has complex procedures, many inspection items, cumbersome operations, high inspection costs, and time-consuming and laborious. [0004] 2. The traditional curtain wall detection technology is no longer applicable to the glass curtain wall that has been installed and used. There is no on-site detection method for the overall safety status of t...
