Embodiment Construction

[0050] The detection principle of the present invention is as figure 1 As shown, the tunnel inspection vehicle 2 drives on the left and right lanes of the tunnel 1 respectively, the driving direction is the same, and no traffic restrictions are required. The present invention is installed on the tunnel inspection vehicle 2 as a whole. 3. Mounted sensors: including cameras, thermal imaging cameras and laser scanners to continuously detect the tunnel 1. When driving on the right lane of the tunnel 1, the present invention is in a working state, rotated and positioned at the working position of 0°, and the tunnel inspection vehicle 2 Only detect the right half area of ​​tunnel 1, and complete the image stitching of the driving direction. Such as figure 2 As shown, when driving in the left lane, the rotation is positioned at the working position of 180°, and the left half area of ​​tunnel 1 is detected.

[0051] Such as image 3 As shown, the multi-sensor integrated platform f...

Abstract

The invention discloses a multi-sensor integrated platform for tunnel detection. The multi-sensor integrated platform comprises a mounting base, a rotating mechanism, a rotating holder, an automatic locking mechanism, a manual locking mechanism, a camera holder, an LED (Light Emitting Diode) lamp holder, an infrared thermal imager holder, a laser scanner holder and a control and drive unit; multiple sensors including a camera, an infrared thermal imager, an auxiliary light source and the like are integrated on the rotating holder, and the rotating holder can automatically rotate any angle around the center and can be automatically locked to maintain relative stability under the high-speed operating environment; moreover, the multi-sensor integrated platform is provided with a flexible sensor fixing and precision adjusting mechanism and a reliable locking device, thus ensuring that a tunnel detection trolley can carry out detection at the speed of 0-80Km/h and a tunnel can be quickly and continuously measured without traffic limitation; and the platform can be mounted on a mobile carrier such as an automobile, a train and the like as an independent device.

Description

technical field [0001] The invention relates to the technical field of tunnel detection, in particular to a tunnel detection multi-sensor integration platform. Background technique [0002] Tunnels play an extremely important role in highway, railway and urban rail transit systems. Ensuring the quality and safety of tunnels is the most basic requirement. Since tunnels and underground projects are located in ever-changing rock masses, the external forces they receive are not clear So far, the distribution and value of the external load system are still in the research stage in domestic and foreign academic circles and engineering circles, which determines that the design of tunnels and underground works is based on certain assumptions, and the formation of tunnels and underground works The process has the characteristic of stress state changes from beginning to end. Therefore, the daily inspection of tunnels is particularly important. The most concerned tunnel diseases in tu...
