Description

Technical Field

[0001] The present invention belongs to the field of slope prevention and control and management, and specifically relates to a method for constructing an integrated intelligent management platform for ultra-high and steep slope prevention and control technology. Background Art

[0002] At present, due to the layout requirements of transportation hubs and navigation buildings, a large number of transportation hubs need to pass through extremely high and steep slopes, or some navigation buildings are built in areas near extremely high and steep slopes. Reasonable and efficient prevention and management of extremely high and steep slopes is an issue that needs to be urgently resolved during the construction and operation period of the project, and it also concerns the safety and stability of the entire life cycle of the project.

[0003] Due to the particularity and importance of ultra-high and steep slope projects, the prevention and control of ultra-high and steep slopes requires the management of multiple links such as investigation, design, construction, and monitoring, including the acquisition and centralized processing of multi-source massive data. These data include but are not limited to the displacement data of ultra-high and steep slopes required during the construction process, the real-time morphology of slopes in the spatial geographic database that needs to be frequently changed with the construction, and the safety monitoring data of anchor bolt and anchor cable stress and deformation in the support scheme that needs to be updated in real time. However, the current management method is mainly to manage each link separately, and most of them are still at the stage of paper document archiving. A small number of links, such as monitoring, may have information software with single functions, which cannot realize the deep integration and analysis and mining of data from each link. There are problems such as uncentralized data management, unintelligent management tools, and difficulty in realizing intelligence and visualization. There are also pain points such as slow response to the prompt and handling of sudden problems on site, difficulty in efficiently and quickly locating the location of sudden problems, and inability to achieve efficient collaborative management. The existing ultra-high and steep slope project construction and operation process lacks an integrated and efficient prevention and control system, and cannot achieve real-time visualization management and timely update of high and steep slope detection and protection. Summary of the invention

[0004] The purpose of the present invention is to provide a method for constructing an integrated intelligent management platform for ultra-high and steep slope control technology, so as to realize real-time and all-round slope control data storage, collection and visual analysis, so as to provide a scientific basis for ultra-high and steep slope control decision-making.

[0005] To achieve the above objectives, the technical solution of the present invention is:

[0006] A method for constructing an integrated intelligent management platform for ultra-high and steep slope prevention and control technologies, the method comprising:

[0007] Construct a three-dimensional model of initial topography and landforms and the layout of engineering buildings for the extremely high and steep slope area to be managed, the model including coordinates and elevation data of each point in the extremely high and steep slope area;

[0008] Collect data information of extremely high and steep slope areas through acquisition equipment;

[0009] Storing the collected data information in the three-dimensional model;

[0010] After constructing a three-dimensional model with data information, a visual intelligent management platform with a graphical user interface is built to link the data information of the three-dimensional model with the graphical interactive interface of the user end.

[0011] Furthermore, the construction of the three-dimensional model of the three-dimensional initial terrain and the layout of engineering buildings includes constructing the terrain through timed cruise drones, determining the area to be scanned by the drones, planning the drone take-off and landing routes and photography elevations, setting the acquisition frequency, using drones for cruise sweeping photography, and constructing a real-time three-dimensional model through the sweeping photography results.

[0012] Furthermore, the collecting of data information of the extremely high and steep slope area includes setting a collecting device at a preset position of the extremely high and steep slope to collect terrain data, and the collecting device is connected to the local area network through a network repeater.

[0013] Furthermore, storing the data information into the three-dimensional model includes mapping the data information collected by the collection device to the three-dimensional model established by the drone scanning.

[0014] Furthermore, the data information collected by the acquisition device is mapped to the three-dimensional model established by the drone scanning, including: when the position information of a target measuring point obtained by the drone elevation photography result is [x, y, z], where x, y are coordinate values, and z is the elevation value, assuming that the coordinate position data after mapping conversion in the three-dimensional model is x', y', z', assuming

[0015]

[0016] The mapping relationship is simplified to a combination of rotation, stretching and translation.

[0017]

[0018] The matrix constants a~i refer to the matrix values ​​that need to be determined due to rotation, stretching, and translation.

[0019]

[0020] Assume that the target point is around another point (p x ,p y ,p z) is used for rotation operation, and the right-handed Cartesian coordinate system is used, that is, the positive direction of the rotation angle is counterclockwise. The rotation includes rotation around the x-axis, y-axis, and z-axis. Assume that the rotation angle around the x-axis is α, the rotation angle around the y-axis is β, and the rotation angle around the z-axis is γ. The transformation of rotation around the y-axis is:

[0021]

[0022] The total rotation around the three axes is:

[0023]

[0024] Assume that the relationship between y' and y, and between x' and x projection is as follows:

[0025]

[0026] Mapping using the perspective projection matrix:

[0027] M 视图 =M 正交 M 变换 (Formula 7)

[0028]

[0029] According to formulas 1 to 9, calculate the values ​​of x', y', and z' to get the required M 视图 , the position data of each point in the 3D model is obtained. After obtaining an accurate view, the position information of a target measuring point in the 3D model is obtained.

[0030] Furthermore, in the three-dimensional model, the coordinate position, elevation and recording time are used as access indexes, the data collected by the acquisition device are listed as a collection, the indexes are linked to the terrain coordinates one by one, the terrain data of the ultra-high and steep slope monitoring points are accessed through the access indexes, and the data after the indexes are linked to the terrain coordinates one by one is transmitted to the GUI graphical interactive operation interface on the user side, and the user accesses the data in real time through the three-dimensional model.

[0031] Furthermore, the visual intelligent management platform with a graphical user interface GUI is provided with an alarm threshold of the monitoring parameters. When the measured data of the acquisition equipment exceeds the threshold, a warning is issued, and the problem area and coordinates of the extremely high and steep slope are highlighted on the graphical user interface. The user strengthens the support measures of the extremely high and steep slope according to the specific alarm information. After the support measures are supplemented and strengthened, if the change of the monitoring data does not exceed the threshold, the alarm information on the GUI is cancelled and monitoring continues; if the monitoring data still exceeds the threshold, the alarm information is still displayed in the GUI and the corresponding area is highlighted until the support measures are strengthened so that the monitoring data is below the set threshold.

[0032] The beneficial effects of the present invention are:

[0033] 1. This system integrates regular elevation photography based on drone cruise scanning (used to update the terrain as the project is under construction) and a three-dimensional visualization system of GIS+BIM for coordinate mapping. It can link monitoring data with coordinates, time, etc. and map them one by one to the constructed three-dimensional model, so that the data can be found throughout the entire cycle of project construction and operation. On-site construction, monitoring personnel or owners can also access the data remotely in real time without going to the site and make corresponding decisions as appropriate.

[0034] 2. This method integrates the unattended collection and storage of ultra-high and steep slope data, and realizes the unattended high-frequency and timely updating of the morphology and support parameters of ultra-high and steep slopes, supporting users' offline or remote visual access and operation.

[0035] 3. This system can record and analyze slope displacement, manually input and export data, and set alarm thresholds. When the measured data exceeds the threshold, it will issue a warning in time. At the same time, the stress / strain measurement unit in the anchor rod and anchor cable is connected to the network, which can record and feedback the stress and deformation of the anchor rod and anchor cable in real time, and can scientifically manage the construction and operation of ultra-high and steep slopes. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Figure 1 The invention relates to a method for constructing an integrated intelligent management platform for ultra-high and steep slope prevention and control technology. DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the invention clearer, the present invention is further described below with reference to the accompanying drawings.

[0038] like Figure 1 As shown, the method for constructing an integrated intelligent management platform for ultra-high and steep slope prevention and control technology of the present invention includes four steps: fully automatic terrain construction based on timed cruise drones, real-time collection of information data and coordinate linking, refined BIM+GIS model construction with multi-source information coupling, and a visual management platform with a graphical user interface GUI.

[0039] Step 1: Fully automatic terrain construction based on timed cruise drone

[0040] In the area of ​​the extra-high and steep slopes to be managed, the scope of the drone sweeping area is determined according to the scale of the project, the drone take-off and landing routes and photography elevations are planned, and the acquisition frequency is set. The drone is used for the first cruise sweep photography, and a refined three-dimensional initial terrain and engineering building layout model is constructed based on the Geographic Information System (GIS) and BIM software. The coordinates and elevations of the target monitoring points on the extra-high and steep slopes can be obtained during the drone sweep photography process.

[0041] In order to reconstruct the terrain in a timely and accurate manner, drones are used to continuously conduct regular scanning and photography of the construction area during the operation of the system, so as to construct a real-time three-dimensional model through the scanning results. First, the area that needs to be scanned by the drone (i.e., the specific area where the ultra-high and steep slope is located) needs to be selected according to the project layout frame, and the corresponding coordinates need to be input into the drone control program, the optimal scanning height needs to be determined, and the scanning route and return route need to be set and input into the drone setting program. At the beginning of the project, the project area needs to be scanned and photographed and the terrain needs to be reconstructed at a specific frequency (e.g., no less than once every two days), and the scanning frequency needs to be maintained during the construction and operation period to meet the real-time update of the ultra-high and steep slope terrain.

[0042] Step 2: Real-time collection of information data

[0043] Arrange data acquisition equipment according to demand to realize long-term acquisition of various data of ultra-high and steep slopes, such as displacement, deformation, stress distribution, and deformation and internal force data of various support measures such as anchor rods and cables. When the measured stress or strain data of anchor rods and cables exceeds the maximum stress or strain of anchor rods and cables, new anchor rods and cables should be replaced. Complete the installation, debugging and information transmission test of equipment such as displacement and deformation acquisition, strain gauges and stress meters, photography and video equipment, as well as the installation of network relays and LAN testing.

[0044] During the construction, support and operation of ultra-high and steep slopes, the most important thing is to collect, link and manage the corresponding data of ultra-high and steep slopes. By setting up collection equipment (such as displacement deformation sensors, strain gauges, stress gauges, video collection equipment, etc., hereinafter referred to as node equipment) at specific locations on ultra-high and steep slopes, some key data can be collected, such as terrain-related data such as collection time, location, elevation, deformation and displacement data of slopes, internal forces and deformations of support measures such as anchor cables and anchor rods, on-site photography and real-time video data, etc. All these node devices are connected to the local area network through network repeaters to ensure that the data of the node devices can be accessed in real time from the terminal, and the data can be traced over time.

[0045] We began to use node acquisition equipment to collect data such as displacement, deformation, stress deformation in support, as well as videos, photos, etc., and transmitted the collected data to the terminal in real time through the network relay in the local area network for storage and continuous updating.

[0046] Step 3: Refined BIM+GIS model construction and coordinate linking of multi-source information coupling

[0047] According to the results of elevation photography and geodetic coordinate transformation, based on BIM software and Geographic Information System (GIS), the location of the data set collected from the node equipment is mapped to the refined three-dimensional model established by the drone scanning in the form of point-to-point (such as coordinate position, elevation information and displacement deformation, geological stratigraphic information, support measures, construction progress, monitoring plan, monitoring results, and monitoring time information) and point-to-block (such as the displacement deformation of blocks and dangerous rock masses as a whole and the corresponding monitoring information).

[0048] Due to the influence of the angle of the drone camera lens and the shooting angle, it may be necessary to obtain the real geodetic coordinate value through operations such as stretching, rotation, and translation. Assume that the position information of a certain target measuring point obtained by the drone elevation photography result is [x, y, z], where x, y are coordinate values, and z is the elevation value. The coordinate value or elevation value is based on the geodetic 2000 coordinates. Assume that the coordinate position data after mapping and conversion in the three-dimensional model is x', y', z'. In the present invention, the [x, y, z] is obtained by drone photography, and needs to be stretched, rotated, and translated to obtain x', y', z'. The x', y', z' are absolute values, which are geodetic coordinate values. Assume

[0049]

[0050] The mapping relationship can be simplified to a combination of rotation, stretching and translation, and the general formula can be written as:

[0051]

[0052] The matrix constants a~i refer to the matrix values ​​that need to be determined due to rotation, stretching, and translation. For example, in translation transformation, it can be written as:

[0053]

[0054] Assume that a point is orbiting relative to another point (p x ,p y ,p z) is used for rotation operation, using the right-handed Cartesian coordinate system, that is, the positive direction of the rotation angle is counterclockwise. We can divide the rotation into rotation around the x-axis, y-axis, and z-axis. Let the rotation angle around the x-axis be α, the rotation angle around the y-axis be β, and the rotation angle around the z-axis be γ. The transformation of rotation around the y-axis can be written as:

[0055]

[0056] The total rotation around the three axes can be written as:

[0057]

[0058] Assume that y' and y, x' and x have the following projection relationship:

[0059]

[0060] Mapping using the perspective projection matrix:

[0061] M 视图 =M 正交 M 变换 (Formula 7)

[0062]

[0063]

[0064] According to formulas 1 to 9, the required M can be obtained. 视图 .

[0065] According to formulas 1 to 9, calculate the values ​​of x', y', and z' to get the required M 视图, then the location data of each point in the three-dimensional model is obtained. After obtaining an accurate view, an accurate three-dimensional model is constructed. At this time, the data recorded in the node device (coordinate position, elevation, recording time, geological information, support measures, construction progress, monitoring plan, monitoring results, etc.) are listed as a set with coordinate position, elevation and recording time as access indexes. All data of the point can be easily accessed through the access index, and the coordinate index is accurately linked to the terrain coordinates one by one, so that when a certain position is clicked in the visualized three-dimensional model, detailed information of the terrain data of the position can appear, and the source can be traced according to time, completing the one-to-one mapping of the data in the refined three-dimensional model. Regarding the coordinate index in the present invention, for example, if the coordinate values ​​and elevation values ​​of N position points of the ultra-high steep slope are recorded, N coordinate indexes can be set, and each coordinate index can be clicked, and the coordinate value and elevation value of each position point can be displayed on the screen. When the data acquisition device is set at the position point, the coordinate index of the corresponding position point is clicked, and the screen not only displays the coordinate value and elevation value of the position point, but also displays the data information collected by the data acquisition device of the corresponding position point.

[0066] In the present invention, formulas 1 to 9 are used to establish a refined three-dimensional solid model based on the drone scanning images, and a one-to-one mapping link is established between the collected multi-source data sets and the coordinate points of the refined three-dimensional solid model, that is, the coordinate position corresponds to the data storage position, and when the terminal clicks or accesses a specific point or coordinate, all the data there (coordinate position, elevation information and displacement deformation, geological stratum information, support measures, construction progress, monitoring plan, monitoring results, monitoring time information) can be directly accessed.

[0067] Step 4: Visual management platform with graphical user interface GUI

[0068] After building a three-dimensional model with data collected by node devices, we can build a visual intelligent management platform with a graphical user interface GUI (Graphical User Interface), and transmit the linked data to the user-side GUI graphical interactive operation interface, so that users can access data in real time through the three-dimensional model, achieving the purpose of "click to check, click to see", and achieving full-time data traceability. All-time monitoring data can be accessed anytime and anywhere, and it also supports the input of manually controlled safety warning thresholds.

[0069] In the present invention, the management platform can be accessed offline or remotely through a terminal or the Internet, so that the three-dimensional engineering model can be displayed in real time, and data with node devices at any location can be accessed according to user needs, or the corresponding area can be directly clicked in the three-dimensional model to access the specific data parameters of the corresponding slope and support. It supports querying the topographic parameters of the slope at any time since the data is available and the historical data parameters of the support, and supports manually setting the alarm threshold of the monitoring parameters. When the measured data exceeds the threshold, a warning will be issued in time, and the problem area and coordinates will be highlighted on the graphical user interface to clearly and quickly inform the user of the location of the problem. After strengthening / updating the support measures, once the monitoring value falls back below the safety threshold, the alarm information disappears, and the alarm information is recorded in the system log for later query.

[0070] When the monitoring value exceeds the threshold, the alarm mechanism will be triggered. When the monitoring value exceeds the threshold, the alarm information and the corresponding area will be highlighted in real time on the GUI. At this time, the user will be prompted to make further decisions, and the user needs to strengthen and supplement the support measures in a targeted manner according to the specific alarm information. After the support measures are supplemented, if the change in the monitoring data does not exceed the threshold, the alarm information on the GUI will be cancelled and continuous monitoring will continue; if the monitoring data still exceeds the threshold, the alarm information will still be displayed in the GUI and the corresponding area will be highlighted until the support measures are strengthened so that the monitoring data falls below the threshold.

[0071] If the user sets support measures in the system, the support measures will be updated in the system, and a confirmation prompt will be initiated to the construction personnel to confirm whether the support measures have been completed. Once the construction personnel confirm the information, the system will synchronously update the information on the support construction status and retain the corresponding operation log.

[0072] In the present invention, after the intelligent management platform is established, drones can be used for regular patrol and scanning photography, and the refined three-dimensional terrain and engineering building layout model data constructed can be continuously updated as the project progresses. The data information collected by the drones and node devices is stored in the three-dimensional model, and the data update frequency can be set. According to the set frequency, in the BIM software, the three-dimensional model automatically updates the model data such as coordinate values, displacement data, stress strain and other data based on the data information collected in real time by the drones and node devices.
