Description

Technical Field

[0001] This application relates to the field of building leveling survey, and in particular to a building safety early warning method, system, electronic device and medium. Background Technology

[0002] Uneven settlement of buildings has a significant impact on building safety. Uneven settlement refers to the difference in settlement between the two sides of a building, leading to tilting. There are many causes of uneven settlement, such as over-exploitation of underground resources like groundwater, uneven distribution of foundation soil, or inconsistent compaction. Currently, settlement monitoring typically involves setting settlement observation points on the exterior walls below the first floor, with personnel periodically monitoring these points to determine the degree of settlement. However, the operation of the instruments used for this monitoring is cumbersome and inconvenient. Therefore, finding a more convenient and accurate method for monitoring building settlement has become a challenge. Summary of the Invention

[0003] To facilitate more convenient and accurate settlement monitoring of buildings, this application provides a building safety early warning method, system, electronic device, and medium.

[0004] Firstly, this application provides a building safety early warning method, which adopts the following technical solution: A building safety early warning method includes: Control the rotation of the distance measuring sensor at each settlement observation point, and acquire the distance data collected during the rotation of the distance measuring sensor and the image information of the ground directly below each settlement observation point; Based on the distance data, determine the terrain flatness curve of the ground below each settlement observation point, as well as the straight-line distance to the ground directly below each settlement observation point; Acquire the historical flatness curve of the terrain, the historical straight-line distance to the ground directly below, and the historical image information of the ground directly below for each settlement observation point at the time of the last detection. The settlement value at each settlement observation point is determined based on the aforementioned terrain flatness curve, historical terrain flatness curve, straight-line distance, and historical straight-line distance. The settlement angle at each settlement observation point is determined based on the image information, historical image information, straight-line distance, and historical straight-line distance. The settlement hazard value of a building is determined based on the settlement value, settlement angle, and terrain flatness curve at each settlement observation point, and a warning is issued based on the settlement hazard value.

[0005] By employing the above technical solution, the distance measuring sensor is controlled to rotate. During this rotation, the sensor can collect distances from the settlement observation point to various locations on the ground below. This data, along with image information of the ground directly below the settlement observation point, allows for the accurate determination of the terrain flatness curve and the straight-line distance to the ground directly below the settlement observation point. Based on the terrain flatness curve and historical terrain flatness curves, the subsidence status of the ground below the settlement observation point can be determined. Ignoring the subsidence status of the ground below the settlement observation point would lead to errors in the distance between the settlement observation point and the ground, reducing the accuracy of the settlement value. The image information records the specific conditions of the ground directly below the settlement observation point. Based on historical and current terrain flatness curves, the subsidence status of the ground below can be determined. This, combined with the historical data on the distance from the settlement observation point to the ground directly below, further supports the determination of the subsidence status. The historical and current straight-line distances can accurately determine the settlement value at each settlement observation point. The historical and current image information can determine the shift of features on the ground below between the two settlement observations. Based on the shift changes and the historical and current straight-line distances, the settlement angle at each settlement observation point can be determined through trigonometric function calculations. Settlement value and settlement angle are key factors affecting the hazards of building settlement. Furthermore, the terrain flatness curve records the undulation of the ground below each settlement observation point, thus indicating the density of the soil layer at each settlement observation point. The density also affects building settlement. Therefore, based on the settlement value, settlement angle, and terrain flatness curve at each settlement observation point, the building's settlement hazard value can be accurately determined. Finally, a warning is issued based on the settlement hazard value, which is more convenient and accurate than manual instrument detection.

[0006] In another possible implementation, determining the settlement value at each settlement observation point based on the terrain flatness curve, historical terrain flatness curve, straight-line distance, and historical straight-line distance includes: The target curve segment that completely overlaps with the historical flat terrain curve is obtained by comparing the flat terrain curve. The flat terrain curve and the historical flat terrain curve are superimposed and mapped on a preset coordinate system according to the target curve segment to obtain the first coordinate point of the ground directly below each settlement observation point on the flat terrain curve, and the second coordinate point of the ground directly below each settlement observation point on the historical flat terrain curve. Determine the first distance between the first coordinate point and the second coordinate point, wherein the first distance is the subsidence value of the ground directly below each settlement observation point; The second distance is obtained by subtracting the straight-line distance from the first distance, and the settlement value at each settlement observation point is obtained by subtracting the historical straight-line distance from the second distance.

[0007] In another possible implementation, a reference marker is set on the ground directly below each settlement observation point. The determination of the settlement angle at each settlement observation point based on the image information, historical image information, straight-line distance, and historical straight-line distance includes: The offset angle and first offset distance of the reference mark are obtained by comparing the image information and historical image information. Determine the first area of ​​the reference marker in the image information and the second area of ​​the reference marker in the historical image information, and determine the area ratio of the first area to the second area; The actual offset distance of the reference mark is determined based on the area ratio and the first offset distance. Based on the actual offset distance and offset angle, a right triangle that has offset relative to the reference mark is determined, and the offset distance component of the right-angled side of the triangle perpendicular to the wall is determined. The settlement angle of each settlement observation point is determined based on the offset distance component, the straight distance, and the historical straight distance.

[0008] In another possible implementation, determining the building's settlement hazard value based on the settlement value, settlement angle, and terrain flatness curve at each settlement observation point includes: Obtain the historical settlement value, historical settlement angle, previous settlement detection time, and current time for each settlement observation point, and determine the time interval based on the previous settlement detection time and the current time; The first settlement velocity is calculated based on the time interval and the current settlement value, and the second settlement velocity is calculated based on the time interval and the current settlement angle. Calculate the first angle difference between the settlement angle and the preset settlement angle threshold; The compaction mass of the ground beneath each settlement observation point is determined based on the flat terrain curve. The settlement hazard value of each settlement observation point is determined based on the first settlement velocity, the second settlement velocity, the first angle difference, and the compaction mass. The settlement hazard value of the building is obtained by summing the settlement hazard values ​​of all settlement observation points.

[0009] In another possible implementation, determining the compaction mass of the ground beneath each settlement observation point based on the terrain flatness curve includes: Calculate the similarity between the terrain flatness curve and the historical terrain flatness curve for each settlement observation point; Linear fitting is performed on the terrain flatness curve to obtain a linear function of the terrain flatness curve, and the root mean square error between the linear function and the reference function is calculated to obtain the flatness of the ground below each settlement observation point. Determine the ratio of flatness to similarity, whereby the ratio characterizes the compaction mass of the ground beneath each settlement observation point.

[0010] In another possible implementation, at least two settlement observation points are provided on the exterior facade of the building, and at least two settlement observation points are also provided on the facade opposite to where the settlement observation points are located. The method further includes: Settlement observation points located on the same facade of the building are identified as the target settlement observation point group, and the second angle difference is obtained by subtracting the settlement angle of the corresponding position on the facade opposite to the target settlement observation point group from each settlement angle of the target settlement observation point group. Calculate the second angle difference between each settlement angle of the target settlement observation point group and the corresponding candidate settlement angle; Calculate the variance of all second angle differences; The settlement hazard value of the building is corrected based on the variance to obtain the corrected settlement hazard value.

[0011] Secondly, this application provides a building safety early warning system, which adopts the following technical solution: A building safety early warning system, comprising: The settlement observation device includes a housing, a motor installed inside the housing, a drive assembly installed on the motor, a distance sensor installed on the drive assembly, a camera device installed on the housing, and a wireless transmitter. The distance sensor is electrically connected to the wireless transmitter, and the camera device is electrically connected to the wireless transmitter. The drive assembly is used to drive the distance sensor to rotate, the distance sensor is used to collect distance data, and the camera device is used to collect image information of the ground directly below each settlement observation point. An electronic device, communicatively connected to a settlement monitoring device, is used to execute a building safety early warning method as described in any one of the first aspects.

[0012] By adopting the above technical solution, the settlement observation device is installed at the settlement observation point. The drive component drives the distance sensor to rotate, so that the distance sensor can collect distance data at various positions on the ground below during the rotation. The camera device collects image information below the settlement observation point, and the wireless transmitter sends the distance data and image information to the electronic device. This allows the electronic device to calculate the settlement hazard value of the building and issue a warning based on the settlement hazard value. Compared with manual detection using related instruments, this method is more convenient, faster, and more accurate.

[0013] In another possible implementation, the drive assembly includes a drive gear mounted on the motor output shaft, a driven gear meshing with the drive gear, and a partition mounted on the driven gear; the partition is rotatably connected to the housing, the partition is coaxial with the housing, and the ranging sensor is mounted on the partition.

[0014] By adopting the above technical solution, the rotation of the motor drives the drive gear to rotate, which in turn drives the driven gear to rotate, which in turn drives the partition to rotate, thereby driving the distance sensor to rotate. This allows the distance sensor to collect distance data at various locations on the ground below the settlement observation point during rotation. The coordinated drive of the drive and driven gears enables the distance sensor to rotate more effectively, and the wires of the distance sensor can pass through the partition and along the shaft of the driven gear, facilitating the connection of other components inside the rear housing, such as a wireless transmitter.

[0015] Thirdly, this application provides an electronic device that adopts the following technical solution: An electronic device comprising: At least one processor; Memory; At least one application, wherein the application is stored in memory and configured to be executed by at least one processor, the at least one configuration being for: executing a building safety early warning method as shown in any possible implementation of the first aspect.

[0016] Fourthly, this application provides a computer-readable storage medium, which adopts the following technical solution: A computer-readable storage medium, when the computer program is executed in a computer, causes the computer to perform a building safety early warning method as described in any one of the first aspects.

[0017] In summary, this application includes at least one of the following beneficial technical effects: The distance sensor is controlled to rotate, during which it collects distances from the settlement observation point to various locations on the ground below. This rotation acquires distance data and image information of the ground directly below the settlement observation point. Based on the distance data, the flatness curve of the ground below the settlement observation point and the straight-line distance to the ground directly below can be accurately determined. The flatness curve, along with historical flatness curves, can determine the degree of ground subsidence below the settlement observation point. Ignoring the subsidence condition of the ground below the settlement observation point would lead to errors in the distance between the settlement observation point and the ground, reducing the accuracy of the settlement value. The image information records the specific conditions of the ground directly below the settlement observation point. Based on historical and current flatness curves, the degree of ground subsidence can be determined, combined with the historical straight-line distance from the settlement observation point to the ground directly below from the previous measurement. Furthermore, the current straight-line distance can accurately determine the settlement value at each settlement observation point. The historical image information from the previous observation and the current image information can determine the shift of the features on the ground below between the two settlement observations. Based on the shift changes and the historical and current straight-line distances, the settlement angle at each settlement observation point can be determined through trigonometric function calculations. Settlement value and settlement angle are key factors affecting the hazards of building settlement. In addition, the terrain flatness curve records the undulation of the ground below each settlement observation point, thus indicating the density of the soil layer at each settlement observation point. The density also affects building settlement. Therefore, based on the settlement value, settlement angle, and terrain flatness curve at each settlement observation point, the building's settlement hazard value can be accurately determined. Finally, a warning is issued based on the settlement hazard value, which is more convenient and accurate than manual instrument detection. Attached Figure Description

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] After reading this specification, those skilled in the art may make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments.

Additionally, the character " / " in this article, unless otherwise specified, generally indicates that the preceding and following related objects have an "or" relationship.

[0030] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.

[0031] This application provides a building safety early warning method executed by an electronic device, which can be a server or a terminal device. The server can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smartphone, tablet, laptop, desktop computer, etc., but is not limited to these. The terminal device and the server can be directly or indirectly connected via wired or wireless communication. This application does not impose any limitations on this connection. Figure 1 As shown, the method includes steps S101, S102, S103, S104, S105, and S106, wherein, S101 controls the rotation of the distance measuring sensor at each settlement observation point, and acquires the distance data collected during the rotation of the distance measuring sensor, as well as the image information of the ground directly below each settlement observation point.

[0032] In the embodiments of this application, when constructing buildings or other structures, workers can drill holes in the exterior walls of the building near the ground, and these holes can serve as settlement observation points. Settlement observation points are typically set at two corners on the same exterior wall of the building. When the exterior wall of the building is too long, settlement observation points can also be set every 20 meters.

[0033] Settlement monitoring devices can be installed inside boreholes at settlement monitoring points to conduct long-term continuous monitoring of building settlement. Alternatively, the devices can be placed inside the boreholes for settlement detection when needed. The core component of the settlement monitoring device is a distance sensor, as shown in the reference... Figure 2 , Figure 2 This is a front view of the settlement observation point, where 'a' represents the settlement observation point, and the horizontal line below represents the ground. The distance measuring sensor is arranged according to... Figure 2 The arrows indicate the direction of rotation, and the two dashed lines represent the measurement range of the distance sensor. During rotation, the distance sensor collects real-time distances to various locations on the ground directly below the settlement observation point. The electronic equipment connects to the settlement observation device wirelessly or via Bluetooth, enabling it to acquire the distance data collected by the sensor during rotation. The settlement observation device also features a camera positioned below the settlement observation point to capture images. The electronic equipment acquires these images, which record the specific conditions of the ground directly below the settlement observation point, facilitating subsequent correction of settlement values ​​and ensuring greater accuracy.

[0034] S102, based on distance data, determine the terrain flatness curve of the ground below each settlement observation point, as well as the straight-line distance to the ground directly below each settlement observation point.

[0035] In this embodiment, the electronic device can plot the undulations of the ground below the settlement observation point, i.e., a terrain flatness curve, based on the continuous changes in distance data. The ground below the settlement observation point serves as a reference height point. The settlement and subsidence of the ground below can be determined based on the terrain flatness curve, which facilitates subsequent correction of the building's settlement value. The distance data collected when the distance sensor rotates to the center is the straight-line distance to the ground directly below the settlement observation point. This straight-line distance cannot be used as the settlement value. Because the building may experience uneven settlement, resulting in slight tilting, the settlement observation device is not parallel to the horizontal plane when inside the hole; there is a slight angle between it and the horizontal plane. The settlement value needs to be further calculated using this straight-line distance.

[0036] S103, acquire the historical flat terrain curve, historical straight-line distance to the ground directly below, and historical image information of the ground directly below for each settlement observation point during the last detection.

[0037] In this embodiment of the application, the electronic device stores relevant data from each settlement detection of the building, such as historical flat terrain curves, historical straight-line distances to the ground directly below, and historical image information. By acquiring the data from the previous detection and combining it with the data collected in the current detection, the electronic device can accurately obtain the settlement value of the building during the period from the last detection to the current detection.

[0038] S104. The settlement value at each settlement observation point is determined based on the terrain flatness curve, historical terrain flatness curve, straight-line distance, and historical straight-line distance.

[0039] In this embodiment, the electronic device can determine the ground subsidence between two settlement observation points by comparing the terrain flatness curve with the previous historical flatness curve. The current straight-line distance is the distance from the settlement observation point to the ground directly below. If the ground directly below subsides and the building settles, the settlement measurement will be affected by the subsidence, resulting in a large error in the settlement value. Therefore, by combining the previous historical straight-line distance, the current measured straight-line distance, and the subsidence status of the ground directly below, the settlement value at each settlement observation point can be accurately determined.

[0040] S105, based on image information, historical image information, straight-line distance, and historical straight-line distance, determine the settlement angle at each settlement observation point.

[0041] In this embodiment of the application, the historical image information records the specific conditions of the ground below the settlement observation point when the settlement detection was last carried out, and the current image information records the specific conditions of the ground directly below between the two settlement detections. By comparing these two images, the changes that have occurred on the ground directly below can be determined, that is, the offset of the ground features compared to the previous shooting. Based on the offset (image information, historical image information), the previous historical straight-line distance and the current straight-line distance, the settlement angle at each settlement observation point can be determined by trigonometric functions.

[0042] S106 determines the settlement hazard value of a building based on the settlement value, settlement angle, and terrain flatness curve at each settlement observation point, and issues a warning based on the settlement hazard value.

[0043] In this embodiment, the settlement value and settlement angle at each settlement observation point are key factors affecting the building's settlement hazards. Therefore, the overall building's hazard caused by settlement, i.e., the settlement hazard value, can be comprehensively determined based on the settlement value and settlement angle at each observation point. Once the electronic device determines the settlement hazard value, it can issue a warning, allowing staff to quickly and intuitively understand the degree of building settlement hazard. Specifically, the electronic device can be set with a preset hazard threshold. If the settlement hazard value reaches the preset threshold, a prompt message is output, such as controlling a buzzer to sound or controlling a display device to show the text message "Building settlement hazard level too high." By analyzing the distance measurement data collected by the distance sensor and the image information collected by the camera device, combined with relevant data from the previous settlement observation, the subsidence situation of the ground below the settlement observation point can be determined, thereby correcting for a more accurate settlement value and settlement angle, which is more convenient and accurate than manual detection using instruments.

[0044] One possible implementation of this application embodiment determines the settlement value at each settlement observation point based on the terrain flatness curve, historical terrain flatness curve, straight-line distance, and historical straight-line distance. Specifically, this includes steps S1041 (not shown in the figure), S1042 (not shown in the figure), S1043 (not shown in the figure), and S1044 (not shown in the figure), wherein... S1041, compare the flat terrain curve with the historical flat terrain curve to obtain the target curve segment that completely overlaps.

[0045] In the embodiments of this application, the electronic device can perform comparison using a discrete comparison method. That is, the two curves are discretized into dense point sets, and a spatial index structure (such as a KD-tree) is established for the point set of each curve. Point pairs with a distance less than a threshold ε between the two point sets are found, and the continuous sequence of matching points is the target curve segment. The target curve segment is the location where the ground below the settlement observation point did not collapse or deform during the two settlement observation periods.

[0046] S1042, Overlay and map the flat terrain curve and the historical flat terrain curve on the preset coordinate system according to the target curve segment to obtain the first coordinate point of the ground directly below each settlement observation point on the flat terrain curve, and the second coordinate point of the ground directly below each settlement observation point on the historical flat terrain curve.

[0047] In this embodiment of the application, the electronic device performs an overlay mapping on the flat terrain curve and the historical flat terrain curve according to the determined target curve segment that has not collapsed or deformed. This means placing the flat terrain curve and the historical flat terrain curve at the same horizontal level, thereby facilitating the determination of the ground subsidence status directly below the settlement observation point. The electronic device determines a first coordinate point on the flat terrain curve in the overlay mapping and a second coordinate point on the historical flat terrain curve. Both the first and second coordinate points represent the ground directly below the two settlement observation points.

[0048] S1043, determine the first distance between the first coordinate point and the second coordinate point.

[0049] The first distance is the subsidence value of the ground directly below each settlement observation point.

[0050] In the embodiments of this application, the electronic device can calculate the first distance between the first coordinate point and the second coordinate point using the distance formula between two points, or calculate the difference between the ordinates of the first coordinate point and the second coordinate point to obtain the first distance. The first distance is the collapse distance of the ground directly below.

[0051] S1044, the second distance is obtained by subtracting the straight-line distance from the first distance, and the settlement value at each settlement observation point is obtained by subtracting the historical straight-line distance from the second distance.

[0052] For the embodiments of this application, refer to Figure 3 The dashed line represents the ground undulation during this settlement observation, i.e., the flat terrain curve. The straight line above and immediately adjacent to the dashed line represents the historical flat terrain curve during the previous observation. Point 'a' is the location of the settlement observation point during the previous settlement detection, and point 'a' is the location of the settlement observation point during this settlement detection. The historical straight-line distance from the previous observation is x1, the current straight-line distance is x2, and the first distance of ground subsidence directly below is x3. The electronic device subtracts the first distance x3 from the straight-line distance x2 to obtain the distance from the current settlement observation point to the ground directly below it during the previous settlement observation, i.e., the second distance x4. Then, the electronic device subtracts the second distance x4 from the historical straight-line distance x1 to obtain the settlement distance of the settlement observation point after the previous settlement observation, i.e., the settlement value y. By determining the subsidence depth of the ground directly below the settlement observation point, the ground reference height for settlement observation is corrected. The settlement value determined using the distances from the previous and current settlement observation points to the ground directly below is more accurate.

[0053] In one possible implementation of this application embodiment, a reference mark is set on the ground directly below each settlement observation point. In step S105, the settlement angle at each settlement observation point is determined based on image information, historical image information, straight-line distance, and historical straight-line distance. Specifically, this includes steps S1051 (not shown in the figure), S1052 (not shown in the figure), S1053 (not shown in the figure), and S1054 (not shown in the figure). S1051, the offset angle and first offset distance of the reference mark are obtained by comparing the image information and historical image information.

[0054] For the embodiments of this application, refer to Figure 4 , Figure 4 The perspective is essentially a top-down view of the ground below the settlement observation point. Figure 4 Point b in the diagram represents the position of the reference marker during the previous settlement observation, b' represents the position of the reference marker during the current settlement observation, angle β represents the offset angle after the reference marker's position changes, and x5 represents the first offset distance. The reference marker can be a circular metal plate, fixed to the ground below the settlement observation point by screws, etc. The electronic equipment compares the image information with the previous historical image information to determine the offset of the reference marker between the two settlement observations. The electronic equipment can map the reference marker in a Cartesian coordinate system, thereby determining the offset angle and the first offset distance. Because ground subsidence may occur, changing the position of the settlement observation point, and uneven settlement may cause slight tilting of the building, resulting in a change in the viewing angle at the settlement observation point, the first offset distance is only the projected distance of the reference marker's offset, not the actual distance. The offset angle is the offset angle caused by the change in the position of the reference marker on the horizontal plane during the two settlement observations.

[0055] S1052, the true offset distance of the reference mark can be determined based on the first offset distance and the first distance.

[0056] In this embodiment, the first distance is the subsidence depth of the ground directly below the settlement observation point, which is also the distance the reference marker descends during the two settlement observations. The first offset distance is obtained by comparing image information and historical image information. That is, the first offset distance is the true offset distance of the reference marker in the projected distance. The first offset distance and the first distance are equivalent to the two legs of a right triangle. Therefore, the electronic device can calculate the true offset distance of the reference marker based on the first offset distance and the first distance using the Pythagorean theorem.

[0057] S1053, based on the actual offset distance and offset angle, determine the right triangle that is offset from the reference mark, and determine the offset distance component of the right-angled side of the triangle that is perpendicular to the wall.

[0058] In this embodiment of the application, the electronic device can determine a right triangle based on the actual offset distance and the offset angle. The actual offset distance is used as the hypotenuse, and the offset distance component of the right-angled side perpendicular to the wall can be obtained by calculating the offset distance component of the right-angled side of the triangle using trigonometric functions in combination with the offset angle. Since the reference mark is offset but the ranging sensor is still facing directly below the settlement observation point to collect the straight-line distance, the offset distance component is the distance between the current straight-line distance point on the ground directly below and the previous historical straight-line distance point on the ground directly below.

[0059] S1054 determines the settlement angle of each settlement observation point based on the offset distance component, straight distance, and historical straight distance.

[0060] In this embodiment, the electronic device can determine a complete triangle based on the offset distance component, the straight-line distance, and the historical straight-line distance. After determining the complete triangle, the electronic device can determine the angle between the two lines representing the straight-line distance and the historical straight-line distance, i.e., the settlement angle. Determining the offset of the reference marker through image information and historical image information, and thus determining the settlement angle, is more accurate and convenient. In other embodiments, the settlement observation device can also be equipped with an angle sensor to collect the offset angle at each settlement observation point. Alternatively, the electronic device can input the settlement observation point, offset distance component, the straight line representing the straight-line distance, the straight line representing the historical straight-line distance, the offset angle, and the position of the reference marker in the image information and historical image information into a three-dimensional spatial coordinate system for spatial vector calculation to obtain the settlement angle of each settlement observation point. Alternatively, the electronic device can input the settlement observation point, offset distance component, the straight line representing the straight-line distance, the straight line representing the historical straight-line distance, the offset angle, and the position of the reference marker in the image information and historical image information into a trained network model to calculate the settlement angle at each settlement observation point on the building. The network model can be a trained convolutional neural network model.

[0061] One possible implementation of this application embodiment is that step S106 determines the building's settlement risk value based on the settlement value, settlement angle, and terrain flatness curve at each settlement observation point. Specifically, this includes steps S1061 (not shown in the figure), S1062 (not shown in the figure), S1063 (not shown in the figure), S1064 (not shown in the figure), S1065 (not shown in the figure), and S1066 (not shown in the figure). S1061, obtain the historical settlement value, historical settlement angle, last settlement detection time and current time for each settlement observation point, and determine the time interval based on the last settlement detection time and the current time.

[0062] In this embodiment of the application, the previous historical settlement value, historical settlement angle, and previous settlement detection time can be stored in a cloud server or a local storage medium within the electronic device. The current time can be obtained by the electronic device via the Internet or a local clock chip. The electronic device subtracts the previous settlement detection time from the current time to obtain the time interval between two settlement detections.

[0063] S1062, calculate the first settlement velocity based on the time interval and the current settlement value, and calculate the second settlement velocity based on the time interval and the current settlement angle.

[0064] In this embodiment of the application, the electronic device can obtain the first settlement velocity of the building by dividing the current settlement value by the time interval, and then the electronic device can obtain the second settlement velocity of the angle tilt by dividing the current settlement angle by the time interval.

[0065] S1063, calculate the first angle difference between the settlement angle and the preset settlement angle threshold.

[0066] In this embodiment of the application, a preset settlement angle threshold is used as the dividing point for excessive building tilt angle. When the preset settlement angle threshold is reached, it indicates that the building's settlement and tilt are too large, and the degree of danger is high. Therefore, the electronic device calculates the first angle difference between the settlement angle and the preset settlement angle threshold. The larger the first angle difference, the smaller the building tilt, and the safer the building.

[0067] S1064, based on the flat terrain curve, determines the compaction mass of the ground beneath each settlement observation point.

[0068] In the embodiments of this application, the terrain flatness curve of the ground below the settlement observation point represents the undulation of the ground below the settlement observation point. The greater the undulation of the ground, the looser and more unstable the soil layer below the ground is. The greater the possibility of more severe settlement of the building in such an environment, the more the electronic device determines the compaction mass of the ground below each settlement observation point based on the terrain flatness curve. The higher the compaction mass, the more stable the geological conditions are and the safer the building is.

[0069] S1065, the settlement hazard value of each settlement observation point is determined based on the first settlement velocity, the second settlement velocity, the first angle difference, and the compaction mass.

[0070] In summary, for the embodiments of this application, the first settlement velocity, the second settlement velocity, the first angle difference, and the compaction mass are all key factors affecting the degree of settlement hazard at each settlement observation point. Therefore, staff can set corresponding coefficients for the above four key factors and store them in the local storage medium of the electronic device. After the electronic device determines the above four key factors, it normalizes the above four factors respectively. Then, the electronic device can call the corresponding coefficients to perform weighted calculation on the normalized values ​​to obtain the settlement hazard value of each settlement observation point.

[0071] S1066, summing the settlement hazard values ​​of all settlement observation points yields the building's settlement hazard value.

[0072] In this embodiment, the electronic device calculates the settlement hazard value of all settlement observation points of the building and then sums all the settlement hazard values ​​to obtain the overall settlement hazard value of the building. The settlement hazard value determined by comprehensively analyzing key factors affecting building settlement hazards, such as the first settlement velocity and the second settlement velocity, is more accurate.

[0073] One possible implementation of this application embodiment is that step S1064, which determines the compaction mass of the ground below each settlement observation point based on the terrain flatness curve, specifically includes steps Sa (not shown in the figure), Sb (not shown in the figure), and Sc (not shown in the figure), wherein... Sa calculates the similarity between the terrain flatness curve and the historical terrain flatness curve for each settlement observation point.

[0074] In the embodiments of this application, the electronic device can calculate the similarity between the terrain flatness curve and the historical terrain flatness curve by calculating the cosine distance. The higher the similarity, the less the ground below the settlement observation point has undergone deformation such as collapse during the two settlement observations, and the shallower the deformation. This indicates that the geology below the settlement observation point is more stable and has a higher degree of compaction. Conversely, it indicates that the geology below the settlement observation point is less stable and has a lower degree of compaction.

[0075] Sb is obtained by linearly fitting the terrain flatness curve to obtain a linear function of the terrain flatness curve. The root mean square error between the linear function and the reference function is calculated to obtain the flatness of the ground below each settlement observation point.

[0076] In the embodiments of this application, the electronic device obtains a linear function by linearly fitting the terrain flatness curve using Origin software, or by using the least squares method. The reference function is a function that characterizes the ground level with small undulations. Then, the vertical distance or vertical deviation from each point on the linear function to the reference function is calculated, or the residual is directly calculated. The flatness is then obtained by calculating the root mean square error (RMSE) based on the vertical distance or vertical deviation. The smaller the RMSE, the straighter and flatter the terrain flatness curve.

[0077] Sc determines the ratio of flatness to similarity, which characterizes the compaction mass of the ground beneath each settlement observation point.

[0078] In the embodiments of this application, a higher similarity indicates that the geology below the settlement observation point is more stable and dense, while a larger root mean square error indicates that the geology below the settlement observation point is less stable and less dense. The electronic device obtains a ratio by dividing the flatness by the similarity. A larger ratio indicates that the geology is less stable and less dense, while a smaller ratio indicates that the geology is more stable and dense. Therefore, using this ratio as a characterization of the density quality of the ground below the settlement observation point is more accurate and intuitive.

[0079] In one possible implementation of this application embodiment, at least two settlement observation points are provided on the exterior facade of the building, and at least two settlement observation points are also provided on the facade opposite to the settlement observation points. Following step S106, steps S107 (not shown in the figure), S108 (not shown in the figure), and S109 (not shown in the figure) are further included. S107, the settlement observation points located on the same facade of the building are identified as the target settlement observation point group, and the second angle difference is obtained by subtracting the settlement angle of the corresponding position on the facade opposite to the target settlement observation point group from each settlement angle of the target settlement observation point group.

[0080] In this embodiment, the electronic device identifies settlement observation points located on the same facade as a group, i.e., a target settlement observation point group. If each settlement observation point is equipped with a settlement observation device, each device has a corresponding number, and each observation point also has a corresponding number. The device numbers and observation point numbers are correlated, and the electronic device stores the settlement observation points located on the same facade. Therefore, the electronic device can identify the target settlement observation point group. If a worker uses a settlement observation device to sequentially detect each settlement observation point on the building, the worker can detect the points sequentially according to their numerical order, and the data obtained by the electronic device can be accurately matched to the settlement observation points.

[0081] If a building experiences uneven settlement, ideally, the settlement angle on the same facade is the same as the settlement angle on the opposite facade, but the direction of settlement tilt is opposite. Therefore, the electronic equipment subtracts the settlement angle at the corresponding position on the opposite facade from the settlement angle at each settlement observation point within the target settlement observation point group to obtain a second angle difference. If the second angle difference is 0, it indicates that the building has experienced ideal uneven settlement in the area between these two settlement observation points, meaning that the tilt angles on both sides of the building in this area are the same but in opposite directions. If the difference is not 0, it indicates that non-ideal uneven settlement has occurred, which increases the risk of cracks in the building.

[0082] S108, calculate the variance of all second angle differences.

[0083] In the embodiments of this application, the electronic device uses the variance calculation formula to calculate the variance of all second angle differences. The larger the variance, the more it indicates that the settlement tilt angles of different areas on the two opposite facades of the building are different and the angle tilt differences are large, which has a greater impact on the structural safety of the building. Conversely, the settlement tilt angles of different areas on the two opposite facades are different but the angle tilt differences are small, which has a smaller impact on the structural safety of the building.

[0084] S109, Correct the settlement hazard value of the building based on variance to obtain the corrected settlement hazard value.

[0085] In this embodiment of the application, after the electronic device determines the variance, the corrected settlement hazard value can be obtained by adding the variance to the building's settlement hazard value. Alternatively, the corrected value can be calculated using the variance and a corresponding preset coefficient, and then added to the corrected value to obtain the corrected settlement hazard value. By utilizing the differences in settlement tilt angles between different areas of the relative facade, the settlement hazard value is corrected, thus combining the uneven settlement under non-ideal conditions to obtain a more accurate and comprehensive settlement hazard value.

[0086] Furthermore, the electronic device can store a 3D model of the building. Staff can mark the location of each settlement observation point on the 3D model. Two settlement observation points at corresponding positions on two opposite facades each manage a specific building area. These two points form a group. Different building areas have different structures. The 3D model can mark the key components that have the greatest impact on the building's structural safety, such as load-bearing columns, beams, and walls. Then, the proportion of key components to all components within the building area corresponding to each group of settlement observation points is determined. The larger the proportion of key components within a group of settlement observation points, the less damage the corresponding building area suffers when the settlement tilt angle of that group of observation points is different. This building area can withstand greater and more severe settlement hazards. Conversely, a smaller proportion of key components indicates a weaker ability to withstand uneven settlement, meaning the building area will suffer greater settlement hazards when uneven settlement occurs. Therefore, electronic devices can correct the second angle difference based on the proportion of key components in different building areas. For example, the angle difference threshold for different building areas can be determined based on the proportion of key components; that is, the angle difference threshold is also larger for areas with a larger proportion of key components. When the second angle difference reaches the corresponding threshold, a correction value is added to the second angle difference, and the subsequent variance is calculated using the correction value. If the second angle difference does not reach the corresponding threshold, the second angle difference can be corrected to 0, meaning that there is no serious settlement hazard in this building area. Alternatively, a comprehensive analysis can be performed based on the proportion of key components in different building areas and the corresponding second angle difference to obtain a score for each set of settlement observation points. This score can then be used to calculate the subsequent variance or correct the building's settlement hazard value.

[0099] This application provides a computer-readable storage medium storing a computer program that, when run on a computer, enables the computer to execute the corresponding content in the aforementioned method embodiments. Compared with related technologies, this application embodiment controls the rotation of a ranging sensor. During the rotation, the ranging sensor can collect the distance from the settlement observation point to various locations on the ground below, acquiring distance data collected during the rotation and image information of the ground directly below the settlement observation point. Based on the distance data, the terrain flatness curve and the straight-line distance to the ground directly below the settlement observation point can be accurately determined. Based on the terrain flatness curve and historical terrain flatness curves, the subsidence status of the ground below the settlement observation point can be determined. If the subsidence status of the ground below the settlement observation point is not considered, errors will occur in the distance between the settlement observation point and the ground, reducing the accuracy of the settlement value. The image information records the specific situation of the ground directly below the settlement observation point. Based on historical terrain flatness curves and the current terrain flatness curve, the subsidence status of the ground below can be determined, combined with the previously detected distance from the settlement observation point to the ground directly below. The historical and current straight-line distances can accurately determine the settlement value at each settlement observation point. The previous historical image information and the current image information can determine the shift of the features on the ground below between the two settlement observations. Based on the shift changes and the previous and current straight-line distances, the settlement angle at each settlement observation point can be determined by trigonometric function calculations. Settlement value and settlement angle are key factors affecting the hazards of building settlement. Furthermore, the terrain flatness curve records the undulation of the ground below each settlement observation point, thus indicating the density of the soil layer at each settlement observation point. The density also affects building settlement. Therefore, based on the settlement value, settlement angle, and terrain flatness curve at each settlement observation point, the settlement hazard value of the building can be accurately determined. Finally, a warning can be issued based on the settlement hazard value, which is more convenient and accurate than manual instrument detection.
