Vehicular highway tunnel rapid detection system

Abstract

The invention discloses a vehicular highway tunnel rapid detection system including three parts of a visual detection device, a vehicular fixing device and a vehicle speed measuring device; the visual collecting device is used for collecting a tunnel lining image and a cross section size, and comprises a supporting rod, a support seat, a connection piece, a scanner installation rod and a scanner installation bracket; the vehicular fixing device is used for installation of the visual collecting device on the top of a vehicle, and comprises an aligning platform, a rotary support, a positioning bolt, a supporting platform, a supporting seat and a supporting beam; and the vehicle speed measuring device is used for real-time collection of vehicle traveling displacement and speed data and triggering of a camera and a 3D scanner. The vehicular highway tunnel rapid detection system has strong applicability, convenient use, fast detection speed, high image collection quality and low cost and other advantages, and solves many technical problems in highway tunnel rapid detection system application.

Description

technical field [0001] The invention belongs to the technical field of vehicle-mounted detection, and in particular relates to a vehicle-mounted rapid detection system for road tunnels. Background technique [0002] At present, tunnel inspection needs to close the traffic, usually with the help of aerial work vehicles, manual or manual instruments to complete the inspection task. This method based on manual detection has low work efficiency, high degree of personal subjectivity, high cost and high risk, and cannot meet the requirements of fast and accurate detection. "Technical Specifications for Highway Tunnel Maintenance" (JTG_H12-2015) has added frequent inspection items, and the frequency of inspection has also increased significantly, and encourages the use of information technology to carry out tunnel structure inspection. It is impossible to manage disease information, and it is difficult to make statistics and analyze the development trend of diseases. [0003] In ...

AI Technical Summary

Problems solved by technology

Compared with highway pavement and railway tunnels, highway tunnels have complex section shapes, diverse internal lighting conditions, and many types of diseases. The detection process is greatly affected by traffic flow, driving trajectory, and multi-dimensional vibration of the environment. Research Difficulty in Intelligent Detection

[0004] The tunnel images of several existing products are taken synchronously by multiple cameras. Cameras, light sources, sensors and other equipment are integrated into a huge vehicle-mounted system, which has problems such as complex system, large amount of data, and high cost, which also limits the application of this technology. Wide application in the field of rapid detection of highway tunnels
