A device and system for monitoring spatial displacement in rock and soil based on image recognition

Abstract

The invention relates to a device and system for monitoring spatial displacement in rock and soil based on image recognition. The spherical bearing in the body (the outer ring is fixedly connected with the box body, the inner ring is a sphere and is provided with a cylindrical through hole, the central axis of the cylindrical through hole passes through the center of the inner ring and is perpendicular to the horizontal plane), three cameras (the lenses are respectively Facing the upper bottom plate, the front side plate and the right side plate, and the central axis is perpendicular to the plates facing each other; it is located above the cylindrical through hole and is fixedly connected with the inner ring of the spherical bearing; each is connected with a power cord and a Transmission line connection) and balance weight (located below the cylindrical through hole, and fixedly connected with the inner ring of the spherical bearing); the system includes more than two devices, and the box body in the device is laid as a node to form a three-dimensional space grid. The device and system of the invention can effectively monitor the spatial displacement in the rock and soil body.

Description

technical field [0001] The invention belongs to the technical field of displacement monitoring and sensing of rock and soil in civil engineering, and relates to a device and system for monitoring spatial displacement in rock and soil based on image recognition, in particular to a method for monitoring and sensing the whole body of soil under the action of external load or environment A device for displacement and its changing tendency. Background technique [0002] In recent years, with the rapid development of the country's economy, it has attached great importance to the economic development of the western region, and more and more investment has been made in the construction of transportation infrastructure in the western region. There are many mountainous areas in the western region, with large ups and downs. It is difficult and costly to build expressways, bridges, and tunnels. Some natural disasters often occur in mountainous areas. Slopes slip under the erosion of ra...

Problems solved by technology

At present, there is not much early warning work on slope disasters in China. In fact, many complex geology often encounter disasters such as mudslides, landslides, and collapses, causing damage to passing vehicles and causing huge damage to people's lives and property. It is an effective measure to ensure the safety of the slope and minimize the property loss and casualties caused by the landslide, which is to monitor the slope deformation.

Of course, not only problems like slopes need to be monitored, but many problems in real life require monitoring devices, such as the deformation of the soil inside the tunnel, the deformation of the foundation soil of the road, and the deformation of the foundation pit, etc. For these problems in the soil Soil deformation inside the body or rock, there is no relatively mature technology in China to solve this problem

As we all know, the occurrence of various geotechnical and underground engineering disasters starts from the internal deformation of the soil. The initial damage state of the soil is difficult to detect in real time only by the external displacement monitoring device, which makes the slope, landslide and other engineering geology Disaster early warning monitoring and forecast lag, resulting in greater loss of life and property
