Embodiment 1

[0062] as attached figure 1 And attached figure 2 As shown, a specific embodiment of the bridge inspection system based on the method of the present invention is used for bridge 7 inspections, including: unmanned aerial vehicle 1, data transmission module 3, ground control center 4, and carried on the unmanned aerial vehicle 1 on the data acquisition module 2. The UAV 1 can be in the form of a fixed-wing UAV, a multi-rotor UAV or an unmanned helicopter. Wherein, the data collection module 2 includes various sensors mounted on the UAV 1 for collecting on-site information of the bridge. The data acquisition module 2 further includes a laser three-dimensional scanner 21 and a ground radar 22 . The UAV 1 collects on-site data of the bridge 7 through a laser three-dimensional scanner 21 and a ground radar 22 . The on-site data collected by the drone 1 is sent to the ground control center 4 through the data transmission module 3 . The data processing and fault detection module...

Embodiment 2

[0075] as attached Figure 8 As shown, a specific embodiment of the bridge inspection method of the present invention, comprising the following steps:

[0076] S101) The unmanned aerial vehicle 1 collects the field data of the bridge 7 through the laser three-dimensional scanner 21 and the ground radar 22 carried on it;

[0077] S102) The on-site data collected by the UAV 1 is sent to the ground control center 4 through the data transmission module 3;

[0078] S103) The data processing and fault detection module 5 of the ground control center 4 processes the laser three-dimensional scanning data collected by the laser three-dimensional scanner 21 to complete the three-dimensional modeling of the detected area of ​​the bridge 7, and at the same time, the radar echo collected by the ground radar 22 wave data processing;

[0079] S104) The data processing and fault detection module 5 detects the defect and the position of the defect of the bridge 7 by analyzing the three-dimens...

Abstract

The invention discloses a bridge inspection method. The bridge inspection method comprises the following steps: acquiring field data of a bridge by an unmanned aerial vehicle through a laser three-dimensional scanner and a geological radar which are mounted thereon, sending the field data acquired by the unmanned aerial vehicle to a ground control center through a data transmission module, processing laser three-dimensional scanning data acquired by the laser three-dimensional scanner to complete three-dimensional modeling of a detected area of the bridge and processing radar echo data acquired by the geological radar by a data processing and fault detection module of the ground control center, and analyzing the three-dimensional modeling and the radar echo data to detect defects of the bridge and positions of the defects by the data processing and fault detection module. By the bridge inspection method, the technical problems of high cost, low efficiency, single means and low reliability of the existing bridge inspection method can be solved.

Description

technical field [0001] The invention relates to the field of engineering measurement, in particular to a bridge inspection method, in particular to an inspection system applied to railway bridges. Background technique [0002] As of 2013, the total mileage of domestic railways has exceeded 100,000 kilometers, and the operating mileage of high-speed rail has reached nearly 10,000 kilometers. Calculated based on the proportion of bridges accounting for 52% of the lines, there are about 5,000 kilometers of high-speed rail bridges in my country. For example, the accumulative length of the Beijing-Tianjin intercity bridge accounts for 86.6% of the total length of the main line, 80.5% for the Beijing-Shanghai high-speed railway, 94.0% for the Guangzhou-Zhuhai intercity bridge, 48.5% for the Wuhan-Guangzhou Railway, and 74.3% for the Harbin-Dalian Railway. According to the "Medium and Long-term Railway Network Planning", the development of my country's high-speed railways focuses o...
