Abstract

The invention provides a tunnel segment slab staggering detection device based on a millimeter wave sensor and a tunnel segment slab staggering detection method based on a millimeter wave sensor. Thedetection device comprises a rotating shaft, and first millimeter wave radar ranging sensors and second millimeter wave radar ranging sensors are mounted on the rotating shaft; the first millimeter wave radar ranging sensors and the second millimeter wave radar ranging sensors are alternately arranged; when the rotating shaft is located at the first rotating position and the rail vehicle is located at the first pipe piece section, the antenna beam centers of the K1 first millimeter wave radar ranging sensors are aligned with K1 first joints located above the rail in the first pipe piece section respectively; and when the rotating shaft is located at the second rotating position and the rail vehicle is located at the second pipe piece section, the antenna beam centers of the K2 second millimeter wave radar ranging sensors are aligned with K2 second joints located above the rail in the second pipe piece section respectively. The purpose of accurate detection is achieved through the advantages of high precision and high resolution of the millimeter-wave radar, the real-time one-time detection can be achieved, and detection efficiency is high.

Description

technical field [0001] The invention relates to a tunnel contour deformation detection system method and device, in particular to a tunnel contour deformation detection system method and device based on an intelligent millimeter wave radar. Background technique [0002] Such as figure 1 As shown, for the tunnel formed by splicing segments, the joint position of the segments often has the problem of misalignment, so it is necessary to detect the joint position of the segments. [0003] For the detection of the joint position of the segments, the existing technology generally adopts the contour deformation detection method, that is, generally uses 3D laser scanning and image vision technology, and the equipment cost is expensive; the anti-interference performance is poor, and the acquired image and point cloud data are easily affected by the tunnel. Harsh environmental interference requires manual fitting and splicing of images and data, which lacks system stability and robus...
