[0002] At present, the safety monitoring model for water gates is based on numerical prediction of pre-buried safety monitoring points, determines whether the facilities corresponding to the current points have safety risks through point threshold, or displays the data of the section through the section diagram. However, the pre-buried safety monitoring points are limited, and cannot predict the safety risks of each component of the water gate. If the safety monitoring points are increased, the cost will be increased, such as equipment cost and operation and maintenance cost. SUMMARY

[0003] The technical problem to be solved by the present application is to provide a water gate safety monitoring method and terminal, which can realize more comprehensive and intuitive risk early warning for the water gate without increasing the cost.

[0004] To solve the above technical problems, one technical solution adopted by the present application is:

[0008] based on the monitoring data, performing three-dimensional space interpolation calculation to obtain the monitoring data of each component in the water gate three-dimensional grid, and comparing the monitoring data of each component with the corresponding preset early warning threshold to obtain the risk early warning result of each component;

[0009] According to the risk early warning result of each component, rendering each component in the water gate BIM model with a preset color corresponding to the risk early warning result to obtain a rendered water gate BIM model.

[0010] To solve the above technical problems, another technical solution adopted by the present application is:

[0011] A water gate safety monitoring terminal, comprising a memory, a processor and a computer program stored in the memory and executable on the processor, wherein the processor implements the following steps when executing the computer program:

[0012] The space where the sluice gate is located is divided into three-dimensional meshes to obtain the sluice gate's three-dimensional mesh, and the sluice gate is modeled in three dimensions to obtain the sluice gate's BIM model;

[0013] The 3D mesh of the sluice gate is bound to the BIM model of the sluice gate, and the monitoring data of the preset safety monitoring stations in the sluice gate structure are obtained.

[0014] Based on the monitoring data, three-dimensional spatial interpolation calculations are performed to obtain the monitoring data of each component in the three-dimensional grid of the sluice gate.

[0015] Based on the risk warning result of each component, each component in the sluice gate BIM model is rendered using a preset color corresponding to the risk warning result, resulting in a rendered sluice gate BIM model.

[0016] The beneficial effects of this invention are as follows: The space surrounding the sluice gate structure is divided into a three-dimensional mesh to obtain a three-dimensional mesh of the sluice gate.

The three-dimensional mesh of the sluice gate is bound to the sluice gate BIM model, and monitoring data from preset safety monitoring stations within the sluice gate structure is acquired. Based on the monitoring data, three-dimensional spatial interpolation calculations are performed to obtain the monitoring data for each component in the sluice gate's three-dimensional mesh.

[0020] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0021] Please refer to Figure 1 A method for monitoring the safety of a sluice gate, comprising the following steps:

[0022] The space where the sluice gate is located is divided into three-dimensional meshes to obtain the sluice gate's three-dimensional mesh, and the sluice gate is modeled in three dimensions to obtain the sluice gate's BIM model;

[0023] The 3D mesh of the sluice gate is bound to the BIM model of the sluice gate, and the monitoring data of the preset safety monitoring stations in the sluice gate structure are obtained.

[0024] Based on the monitoring data, three-dimensional spatial interpolation calculations are performed to obtain the monitoring data of each component in the three-dimensional grid of the sluice gate. The monitoring data of each component is then compared with the corresponding preset early warning threshold to obtain the risk warning result of each component.

[0025] Based on the risk warning result of each component, each component in the sluice gate BIM model is rendered using a preset color corresponding to the risk warning result, resulting in a rendered sluice gate BIM model.

[0026] As can be seen from the above description, the beneficial effects of the present invention are as follows: The space where the sluice gate structure is located is divided into three-dimensional meshes to obtain a three-dimensional mesh of the sluice gate; the sluice gate structure is then modeled in three dimensions to obtain a sluice gate BIM model; the sluice gate three-dimensional mesh is bound to the sluice gate BIM model; monitoring data from preset safety monitoring stations within the sluice gate structure is obtained; three-dimensional spatial interpolation calculations are performed based on the monitoring data to obtain monitoring data for each component in the sluice gate three-dimensional mesh; the monitoring data for each component is compared with the corresponding preset warning threshold to obtain a risk warning result for each component; and each component in the sluice gate BIM model is rendered using a preset color corresponding to the risk warning result to obtain a rendered sluice gate BIM model. The present invention does not require adding more safety monitoring stations; it utilizes the monitoring data from existing safety monitoring stations to obtain monitoring data for each component in the sluice gate three-dimensional mesh through three-dimensional spatial interpolation calculations, resulting in more comprehensive safety monitoring. Rendering each component in the sluice gate BIM model using a preset color corresponding to the risk warning result highlights components with safety issues, allowing for a quick understanding of the current safety status of the sluice gate. Thus, without increasing costs, a more comprehensive and intuitive risk warning for the sluice gate is achieved.

[0027] Furthermore, the binding of the sluice gate's 3D mesh with the sluice gate's BIM model includes:

[0028] Convert the Cartesian coordinates of each component in the sluice gate BIM model to latitude and longitude.

[0029] Each component in the sluice gate BIM model is associated with each component in the sluice gate 3D mesh based on the latitude and longitude.

[0030] As described above, since the positional information of the components in the sluice gate BIM model is in Cartesian coordinates and the positional information of the components in the sluice gate 3D mesh is in latitude and longitude, after converting the Cartesian coordinates of each component in the sluice gate BIM model to latitude and longitude, it is associated with each component in the sluice gate 3D mesh, thereby realizing the rapid binding between the sluice gate 3D mesh and the sluice gate BIM model.

[0031] Furthermore, the step of performing three-dimensional spatial interpolation calculations based on the monitoring data to obtain the monitoring data for each component in the three-dimensional grid of the sluice gate includes:

[0032] The position of the preset safety monitoring station in the sluice gate's three-dimensional grid is obtained based on the position of the preset safety monitoring station in the sluice gate's BIM model.

[0033] Based on the monitoring data of the components corresponding to the positions of the preset safety monitoring stations in the three-dimensional grid of the sluice gate, an interpolation algorithm is used to perform three-dimensional spatial interpolation calculations to obtain the monitoring data of each component in the three-dimensional grid of the sluice gate.

[0034] As described above, the positions of the preset safety monitoring stations in the sluice gate BIM model are obtained, and then the monitoring data of the components corresponding to the positions of the preset safety monitoring stations in the sluice gate 3D grid are used to perform 3D spatial interpolation calculations using an interpolation algorithm to obtain the monitoring data of each component in the sluice gate 3D grid. In this way, more comprehensive sluice gate safety monitoring can be achieved through the existing limited safety monitoring stations, thereby improving the reliability of sluice gate safety monitoring.

[0035] Furthermore, the preset warning threshold includes a first preset warning threshold, a second preset warning threshold, and a third preset warning threshold;

[0036] Also includes:

[0037] Obtain historical monitoring data for each component in the sluice gate BIM model;

[0038] The positive and negative three times the root mean square difference of the historical monitoring data of each component is used as the first preset early warning threshold of each component;

[0039] The maximum and minimum values ​​of the historical monitoring data for each component are used as the second preset early warning threshold for each component.

[0040] The third preset warning threshold for each component is calculated using the minimum probability method based on the historical monitoring data of each component.

[0041] As described above, each component has three preset warning thresholds, each corresponding to a different level of risk. This allows for tiered warnings of risks, making safety monitoring more effective.

[0042] Furthermore, the step of comparing the monitoring data of each component with the corresponding preset early warning threshold to obtain the risk warning result for each component includes:

[0043] For each component, if the monitoring data of the component is less than or equal to the first preset warning threshold, the risk warning result of the component is determined to be no risk.

[0044] If the monitoring data of a component is greater than the first preset warning threshold and is not less than the minimum value or not greater than the maximum value of the second preset warning threshold, then the risk warning result of the component is determined to be a level one risk warning.

[0045] If the monitoring data of a component is less than the minimum value of the second preset warning threshold or greater than the maximum value of the second preset warning threshold, and less than the third preset warning threshold, then the risk warning result of the component is determined to be a level two risk warning.

[0046] If the monitoring data of a component is greater than the third preset warning threshold, then the risk warning result of the component is determined to be a level three risk warning.

[0047] As described above, for each component, the risk warning results include no risk, level 1 risk warning, level 2 risk warning, or level 3 risk warning, so that the corresponding colors can be used for rendering according to different risk warning results, which can more intuitively show the safety status of each component of the sluice gate.

[0048] Please refer to Figure 2 A sluice gate safety monitoring terminal includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it performs the following steps:

[0049] The space where the sluice gate is located is divided into three-dimensional meshes to obtain the sluice gate's three-dimensional mesh, and the sluice gate is modeled in three dimensions to obtain the sluice gate's BIM model;

[0050] The 3D mesh of the sluice gate is bound to the BIM model of the sluice gate, and the monitoring data of the preset safety monitoring stations in the sluice gate structure are obtained.

[0051] Based on the monitoring data, three-dimensional spatial interpolation calculations are performed to obtain the monitoring data of each component in the three-dimensional grid of the sluice gate. The monitoring data of each component is then compared with the corresponding preset early warning threshold to obtain the risk warning result of each component.

[0052] Based on the risk warning result of each component, each component in the sluice gate BIM model is rendered using a preset color corresponding to the risk warning result, resulting in a rendered sluice gate BIM model.

[0053] As can be seen from the above description, the beneficial effects of the present invention are as follows: The space where the sluice gate structure is located is divided into three-dimensional meshes to obtain a three-dimensional mesh of the sluice gate; the sluice gate structure is then modeled in three dimensions to obtain a sluice gate BIM model; the sluice gate three-dimensional mesh is bound to the sluice gate BIM model; monitoring data from preset safety monitoring stations within the sluice gate structure is obtained; three-dimensional spatial interpolation calculations are performed based on the monitoring data to obtain monitoring data for each component in the sluice gate three-dimensional mesh; the monitoring data for each component is compared with the corresponding preset warning threshold to obtain a risk warning result for each component; and each component in the sluice gate BIM model is rendered using a preset color corresponding to the risk warning result to obtain a rendered sluice gate BIM model. The present invention does not require adding more safety monitoring stations; it utilizes the monitoring data from existing safety monitoring stations to obtain monitoring data for each component in the sluice gate three-dimensional mesh through three-dimensional spatial interpolation calculations, resulting in more comprehensive safety monitoring. Rendering each component in the sluice gate BIM model using a preset color corresponding to the risk warning result highlights components with safety issues, allowing for a quick understanding of the current safety status of the sluice gate. Thus, without increasing costs, a more comprehensive and intuitive risk warning for the sluice gate is achieved.

[0054] Furthermore, the binding of the sluice gate's 3D mesh with the sluice gate's BIM model includes:

[0055] Convert the Cartesian coordinates of each component in the sluice gate BIM model to latitude and longitude.

[0056] Each component in the sluice gate BIM model is associated with each component in the sluice gate 3D mesh based on the latitude and longitude.

[0057] As described above, since the positional information of the components in the sluice gate BIM model is in Cartesian coordinates and the positional information of the components in the sluice gate 3D mesh is in latitude and longitude, after converting the Cartesian coordinates of each component in the sluice gate BIM model to latitude and longitude, it is associated with each component in the sluice gate 3D mesh, thereby realizing the rapid binding between the sluice gate 3D mesh and the sluice gate BIM model.

[0058] Furthermore, the step of performing three-dimensional spatial interpolation calculations based on the monitoring data to obtain the monitoring data for each component in the three-dimensional grid of the sluice gate includes:

[0059] The position of the preset safety monitoring station in the sluice gate's three-dimensional grid is obtained based on the position of the preset safety monitoring station in the sluice gate's BIM model.

[0060] Based on the monitoring data of the components corresponding to the positions of the preset safety monitoring stations in the three-dimensional grid of the sluice gate, an interpolation algorithm is used to perform three-dimensional spatial interpolation calculations to obtain the monitoring data of each component in the three-dimensional grid of the sluice gate.

[0061] As described above, the positions of the preset safety monitoring stations in the sluice gate BIM model are obtained, and then the monitoring data of the components corresponding to the positions of the preset safety monitoring stations in the sluice gate 3D grid are used to perform 3D spatial interpolation calculations using an interpolation algorithm to obtain the monitoring data of each component in the sluice gate 3D grid. In this way, more comprehensive sluice gate safety monitoring can be achieved through the existing limited safety monitoring stations, thereby improving the reliability of sluice gate safety monitoring.

[0062] Furthermore, the preset warning threshold includes a first preset warning threshold, a second preset warning threshold, and a third preset warning threshold;

[0063] Also includes:

[0064] Obtain historical monitoring data for each component in the sluice gate BIM model;

[0065] The positive and negative three times the root mean square difference of the historical monitoring data of each component is used as the first preset early warning threshold of each component;

[0066] The maximum and minimum values ​​of the historical monitoring data for each component are used as the second preset early warning threshold for each component.

[0067] The third preset warning threshold for each component is calculated using the minimum probability method based on the historical monitoring data of each component.

[0068] As described above, each component has three preset warning thresholds, each corresponding to a different level of risk. This allows for tiered warnings of risks, making safety monitoring more effective.

[0069] Furthermore, the step of comparing the monitoring data of each component with the corresponding preset early warning threshold to obtain the risk warning result for each component includes:

[0070] For each component, if the monitoring data of the component is less than or equal to the first preset warning threshold, the risk warning result of the component is determined to be no risk.

[0071] If the monitoring data of a component is greater than the first preset warning threshold and is not less than the minimum value or not greater than the maximum value of the second preset warning threshold, then the risk warning result of the component is determined to be a level one risk warning.

[0072] If the monitoring data of a component is less than the minimum value of the second preset warning threshold or greater than the maximum value of the second preset warning threshold, and less than the third preset warning threshold, then the risk warning result of the component is determined to be a level two risk warning.

[0073] If the monitoring data of a component is greater than the third preset warning threshold, then the risk warning result of the component is determined to be a level three risk warning.

[0074] As described above, for each component, the risk warning results obtained by comparing the monitoring data with the preset warning threshold include no risk, level one risk warning, level two risk warning, or level three risk warning. This allows for subsequent rendering using corresponding colors based on different risk warning results, providing a more intuitive display of the safety status of each component of the sluice gate.

[0075] The sluice gate safety monitoring method and terminal described above are applicable to safety monitoring scenarios for sluice gate structures. The following detailed embodiments illustrate these methods:

[0076] Please refer to Figure 1 and Figure 3 Embodiment 1 of the present invention is as follows:

[0077] A method for monitoring the safety of a sluice gate, comprising the following steps:

[0078] S1. Divide the space where the sluice gate is located into a three-dimensional mesh to obtain the three-dimensional mesh of the sluice gate, and perform three-dimensional modeling of the sluice gate to obtain the sluice gate BIM model.

[0079] For example, if the space occupied by the sluice gate structure is 0.125m³ (0.5m×0.5m×0.5m), a cubic 3D grid of the sluice gate can be obtained by directly dividing the space into three dimensions using the maximum and minimum heights and latitude and longitudes of the sluice gate structure.

[0080] S2. Bind the 3D mesh of the sluice gate to the BIM model of the sluice gate, and obtain the monitoring data of the preset safety monitoring stations in the sluice gate structure, specifically including S21-S23:

[0081] S21. Convert the Cartesian coordinates of each component in the BIM model of the sluice gate into latitude and longitude.

[0082] In the sluice gate BIM model, the positional information of each component is in Cartesian coordinates, while in the sluice gate 3D mesh, the positional information of each component is in latitude and longitude (e.g., WGS84). Therefore, converting the Cartesian coordinates in the sluice gate BIM model to latitude and longitude allows for binding with the sluice gate 3D mesh. Figure 3 As shown, Figure 3 The 2D grid is given as a simple representation of the 3D grid of the sluice gate. In actual application, the generated 3D grid of the sluice gate is still 3D. The latitude and longitude obtained after the coordinate transformation of a certain component corresponds to the grid 21. Then the component is bound to the grid 21. The specific transformation method is the existing technology.

[0083] The component can be any sluice gate structure that you want to monitor, such as the gate panel, the wall of the sluice gate, the column of the sluice gate building, etc.

[0084] S22. Associate each component in the sluice gate BIM model with each component in the sluice gate three-dimensional mesh according to the latitude and longitude.

[0085] S23. Obtain monitoring data from the preset safety monitoring stations in the sluice gate structure.

[0086] Specifically, monitoring data from pre-installed safety monitoring stations within the sluice gate structure are acquired at the same time. These pre-installed safety monitoring stations are existing, pre-deployed safety monitoring stations.

[0087] S3. Based on the monitoring data, perform three-dimensional spatial interpolation calculations to obtain the monitoring data of each component in the three-dimensional grid of the sluice gate, and compare the monitoring data of each component with the corresponding preset warning threshold to obtain the risk warning result of each component. The preset warning thresholds include a first preset warning threshold, a second preset warning threshold, and a third preset warning threshold, specifically including S31-S36:

[0088] S31. Based on the location of the preset safety monitoring station in the BIM model of the sluice gate, obtain the location of the preset safety monitoring station in the three-dimensional grid of the sluice gate.

[0089] S32. Based on the monitoring data of the components corresponding to the positions of the preset safety monitoring stations in the three-dimensional grid of the sluice gate, an interpolation algorithm is used to perform three-dimensional spatial interpolation calculation to obtain the monitoring data of each component in the three-dimensional grid of the sluice gate.

[0090] In one optional implementation, the interpolation algorithm includes, but is not limited to, Kriging interpolation, three-dimensional linear interpolation, three-dimensional polynomial interpolation, and cubic spline interpolation. For example, based on the monitoring data of the components corresponding to the positions of preset safety monitoring stations in the three-dimensional grid of the sluice gate, three-dimensional spatial interpolation calculations are performed using the Kriging interpolation method to obtain the monitoring data of each component in the three-dimensional grid of the sluice gate.

[0091] By utilizing existing safety monitoring stations, such as displacement monitoring, it becomes clear that forces within a sluice gate structure are interconnected; when displacement occurs in one location, other connected locations will also experience displacement. Therefore, after obtaining detection values ​​from a limited number of safety monitoring points, interpolation calculations can be used to calculate the possible displacement data for other locations throughout the entire space. This allows for more comprehensive safety monitoring of the sluice gate without the need to add more safety monitoring stations.

[0092] S33. For each component, if the monitoring data of the component is less than or equal to the first preset warning threshold, then the risk warning result of the component is determined to be no risk.

[0093] S34. If the monitoring data of the component is greater than the first preset warning threshold and not less than the minimum value or not greater than the maximum value of the second preset warning threshold, then the risk warning result of the component is determined to be a level one risk warning.

[0094] S35. If the monitoring data of the component is less than the minimum value of the second preset warning threshold or greater than the maximum value of the second preset warning threshold, and less than the third preset warning threshold, then the risk warning result of the component is determined to be a level two risk warning.

[0095] S36. If the monitoring data of the component is greater than the third preset early warning threshold, the risk warning result of the component is determined to be a level three risk warning.

[0096] In one alternative implementation, before S3, the following is also included:

[0097] Obtain historical monitoring data for each component in the sluice gate BIM model;

[0098] The positive and negative three times the root mean square difference of the historical monitoring data of each component is used as the first preset early warning threshold of each component;

[0099] The maximum and minimum values ​​of the historical monitoring data for each component are used as the second preset early warning threshold for each component.

[0100] The third preset warning threshold for each component is calculated using the minimum probability method based on the historical monitoring data of each component. The minimum probability method is an existing technology.

[0101] Each component has three corresponding preset warning thresholds. The risk warning levels corresponding to the first, second, and third preset warning thresholds increase progressively, better reflecting the urgency of safety risks. Data of all components in the sluice gate BIM model are acquired and stored in the system, and the preset warning thresholds for each component are maintained.

[0102] S4. Based on the risk warning result of each component, render each component in the sluice gate BIM model using a preset color corresponding to the risk warning result to obtain the rendered sluice gate BIM model.

[0103] For example, for each component, if the risk warning result of the component is no risk, then the component is rendered in green in the sluice gate BIM model; if the risk warning result of the component is a level one risk warning, then the component is rendered in blue in the sluice gate BIM model; if the risk warning result of the component is a level two risk warning, then the component is rendered in orange in the sluice gate BIM model; and if the risk warning result of the component is a level three risk warning, then the component is rendered in red in the sluice gate BIM model. In this way, the safety status of the entire sluice gate structure can be seen intuitively, and components that may have safety risks can be located more quickly.

[0104] Please refer to Figure 2 Embodiment two of the present invention is as follows:

[0105] A sluice gate safety monitoring terminal includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the various steps of the sluice gate safety monitoring method in Embodiment 1.

[0106] In summary, this invention provides a sluice gate safety monitoring method and terminal. The method involves dividing the space of the sluice gate structure into a three-dimensional mesh to obtain a 3D mesh, and then creating a 3D model of the sluice gate structure to obtain a BIM model. The 3D mesh is then bound to the BIM model, and monitoring data from preset safety monitoring stations within the sluice gate structure is acquired. Based on this monitoring data, 3D spatial interpolation calculations are performed to obtain monitoring data for each component within the 3D mesh. The monitoring data for each component is compared with a corresponding preset warning threshold to obtain a risk warning result for each component. Each component in the BIM model is rendered using a preset color corresponding to the risk warning result, resulting in a rendered BIM model. This invention eliminates the need for additional safety monitoring stations, utilizing existing monitoring data to obtain monitoring data for each component in the 3D mesh through 3D spatial interpolation calculations. This provides more comprehensive safety monitoring. Rendering each component in the BIM model using a preset color corresponding to the risk warning result highlights components with safety issues, allowing for a quick understanding of the current safety status of the sluice gate. Thus, without increasing costs, a more comprehensive and intuitive risk warning for the sluice gate is achieved. In addition, each component has three preset warning thresholds, each corresponding to a different level of risk, which enables graded warnings of risks and makes safety monitoring more effective.
