Description

Technical Field

[0001] The invention belongs to the technical field of slope deformation monitoring, and in particular relates to a slope deformation monitoring and early warning device and method. Background Art

[0002] Slope support refers to the support, reinforcement and protection measures taken on the slope to ensure the safety of the slope and its environment. In the process of modern urbanization, the prevention and early warning of geological disasters are particularly important. With the development of science and technology, traditional manual monitoring methods have gradually been replaced by intelligent and automated monitoring systems. As an important part of urban infrastructure, the stability of slopes is directly related to the safety of people’s lives and property. Traditional slope monitoring methods rely on regular manual inspections, which is not only inefficient, but also difficult to achieve 24-hour uninterrupted monitoring.

[0003] With the development of artificial intelligence technology, especially the progress in the field of computer vision, image recognition technology based on deep learning provides a new solution for slope monitoring. Automatic slope monitoring and recognition cameras are deployed in key areas of the slope. The automatic slope monitoring and recognition cameras are responsible for capturing the real-time detection of landslides, rockfalls, mudslides and other phenomena on the slope. Once an abnormal situation is found, the system can immediately issue an early warning signal to remind relevant departments to take emergency measures to minimize the loss of personnel and property. The automatic monitoring and recognition cameras with advanced image recognition and data analysis technology can automatically trigger an alarm before the danger comes, and send timely early warning information to relevant departments and residents, which can improve the response speed and effect of sudden natural disasters and provide strong support for early warning and emergency response.

[0004] The patent document with announcement number CN216482806U discloses a slope lattice beam anchor structure support monitor, including a slope and a monitoring component, wherein a lattice beam is fixed on the slope surface, and three groups of mounting plates are arranged on the lattice beam, and each group of mounting plates is provided with two, which are located at both ends of the lattice beam, and the monitoring component includes a fixed rod fixed on both ends of the side of the slope, a cross bar with one end vertically fixed to one side of the fixed rod and the other end extending to the slope surface, and a first camera installed on the upper end of one side of the fixed rod and installed on the upper end of the cross bar near the slope surface, wherein the first camera is in the same straight line with the mounting plates at the top of the lattice beam and the bottom of the lattice beam respectively. This slope lattice beam anchor structure support monitor monitors the mounting plate through the first camera on the fixed rod and the cross bar. When the slope surface slides and collapses, the position of the lattice beam and the mounting plate changes, and the slope surface can be monitored in real time by monitoring the position of the mounting plate in the first camera.

[0005] The above patent monitors the mounting plate through the first camera on the fixed rod and the cross bar, but the fixed rod and the cross bar are both located on the slope. When the slope slides and collapses, the fixed rod and the cross bar will be displaced, which will then cause the camera to be displaced. It is difficult to ensure the stability of the camera, which will reduce the monitoring accuracy. In addition, the monitoring process takes a long time and is affected by the outdoor environment. It is easy for the surface of the camera to be covered with dust, which makes it difficult to clean the dust, thereby reducing the monitoring quality of the picture.

[0006] The patent document with announcement number CN117190893A discloses an intelligent real-time monitoring device for high slope deformation, which belongs to the field of slope protection. It includes a placement box, a camera is connected to the upper side of the placement box, and a sound and light alarm is electrically connected to one side of the camera. A protection box that can surround the placement box is provided on the outer side of the placement box, and a groove for placing the placement box is opened downward on the upper side of the protection box. A top cover that can block the top groove of the protection box is provided on the upper side of the protection box. A sliding plate is connected to the slope close to the protection box, and a driving component is connected between the sliding plate and the protected box. When the sliding plate moves downward, the top cover can drive the placement box, the camera and the sound and light alarm to be covered in the protection box, which can reduce damage to the equipment when a landslide occurs.

[0007] The camera of the above patent has no dustproof and protective structure on the outside, and the camera needs to be cleaned manually during long-term monitoring. The sliding plate is installed on the inclined surface of the slope. When the slope slides and collapses, it will cause the device to move, and then cause the camera to move, affecting the monitoring effect. Summary of the invention
