Problems solved by technology
[0003] Tunnels will undergo structural deformation after years of use. During tunnel operation, continuous tunnel structural deformation monitoring is an important guarantee for tunnel operation safety. When the lining structure of a shield tunnel is deformed, segment displacement will inevitably occur, and the tube High-pressure bending failure of segment joints will lead to cracks on segments, and even breakage of segment connecting bolts, and damage to the joint structure between adjacent segments

Embodiment Construction
[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments.
[0037] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for the purpose of illustration only and do not represent the only embodiment.
[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood...

The invention relates to an image recognition-based tunnel safety intelligent monitoring and early warning device, which comprises a first detection assembly and a second detection assembly, the second detection assembly is arranged corresponding to the joint of two adjacent segment units, the first detection assembly is arranged on the inner ring of the segment units corresponding to the segment units, and whether cracks appear on the inner wall of a tunnel or not can be acquired through a camera; the second detection assembly is attached to the inner wall of the tunnel, the lining plate structure can transmit displacement applied to the outer side annular wall of the lining plate structure to the end in the circumferential direction of the lining plate structure, the displacement is detected through a sensor at the end, whether the tunnel lining structure deforms or not is judged, and after the sensor detects that the displacement is generated, the lining plate structure is detected. And the first detection assemblies on the two sides are simultaneously driven to start monitoring the inner wall of the tunnel, so that intelligent monitoring and early warning are realized. The lining plate can monitor deformation displacement of the two adjacent segment units at the same time, the plate body of the lining plate corresponds to the segments in the segment units, displacement damage at the joint of any segment of the segment units can be sensed and detected, and monitoring of deformation of the lining plate is more accurate.
Description
technical field [0001] The invention relates to the technical field of tunnel safety monitoring, in particular to an intelligent monitoring and early warning device for tunnel safety based on image recognition. Background technique [0002] With the development of tunnel engineering construction, shield tunnel has become the mainstream tunnel construction method due to its high degree of mechanization, small construction disturbance, strong adaptability to complex geological conditions, and safe and fast construction, and is widely used in urban subways. , railway tunnels and cross-river or cross-sea underwater tunnels. [0003] The tunnel will undergo structural deformation after years of use. During the operation of the tunnel, continuous monitoring of the deformation of the tunnel structure is an important guarantee for the safety of the tunnel operation. When the lining structure of the shield tunnel is deformed, the segment displacement will inevitably occur. The high-...
