Mobile building roof panel structure health detection method

Abstract

The invention discloses a mobile building roof panel structure health detection method. The method comprises the following steps that S1, a mobile mechanism carries a sensor to a position needing to be detected; S2, the mobile mechanism lowers the sensor; and S3, the sensor acquires signals, wherein the sensor lowered by the mobile mechanism in the step S2 is a vibration sensor, the signals collected by the sensors in the step S3 are frequency information of a roof panel structure, and the mobile mechanism in the step S1 is a mobile monitoring robot. A mobile carrying mode is used, the robot is used for carrying the mobile sensor for mobile collection, so that the purpose of traversing all roof panels is achieved, and the uncertainty of the performance degradation positions of the roof panels in an operation state is overcome; two most important problems of monitoring data incompleteness caused by limited sensor types and arrangement positions are solved; an automatic cruise robot carrying vibration acquisition equipment is used, so that roof full-coverage detection can be realized; and mobile vibration signal acquisition is carried out, large-scale routing inspection is carried out on roof panels, and frequency information of structure response is recorded.

Description

technical field [0001] The invention relates to a method for detecting the structure of a building roof panel, in particular to a method for detecting the health of a mobile building roof panel structure. Background technique [0002] The traditional detection method of the roof panel system is to regularly dispatch maintenance personnel to carry out visual inspections, so as to detect local structural looseness, corrosion and other damage in time. According to the provisions of Article 11.1.1 of "JGJ255-2012 Technical Regulations for Skylighting Roofs and Metal Roofs", when the daylighting roof and metal roof panels are completed and accepted, the contractor shall provide the owner with an operation and maintenance manual, which shall include regular maintenance and maintenance requirements , to train repair and maintenance personnel for owners. However, relying on manual maintenance consumes manpower and material resources, the inspection operation is difficult and ineffi...

Problems solved by technology

[0008] 1. A large number of deployments are required;

[0009] 2. Due to discrete distribution points, even if a large number of sensors are deployed, it is still impossible to achieve the purpose of full coverage;

[0010] 3. It is impossible to know whether the layout location is the best location

[0011] 4. Point selection, construction installation, wiring, etc. are extremely inconvenient and costly

[0012] It is not difficult to find that none of the above monitoring methods can solve the following key uncertainties:

[0013] 1) The performance degradation of large-area roof slabs and the randomness of risk occurrence locations under operating conditions;

[0014] 2) Limited sensor types and layout locations lead to incompleteness of monitoring data;

[0015] 3) Environmental impact and test noise lead to acquisition distortion, which affects the accuracy and reliability of monitoring data;
