[0031] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0032] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] Common monitoring methods include inclinometer monitoring, displacement sensor monitoring, global navigation satellite system monitoring, total station monitoring, etc. The difficulties and requirements faced by monitoring include: overcoming the influence of different weather conditions, all-weather automatic monitoring, observation locations that are difficult for personnel to reach, as high accuracy as possible, and cost savings. Therefore, the present application provides an object displacement monitoring device that can monitor at night, in windy weather, etc., which can reduce monitoring costs and improve monitoring accuracy.

[0034] The present application installs the object displacement monitoring device at the displacement sensitive point of the target object to be detected.

[0035] Among them, the displacement sensitive point refers to a specific position or component on an object where the displacement change is more significant and sensitive to the displacement change under external or internal conditions.

[0036] Specifically, in mechanical engineering or structure, displacement sensitive points refer to key locations that can significantly reflect the deformation, movement or vibration characteristics of structures or machine parts such as bridges, buildings, wind turbine towers, aircraft wings, etc., such as the far end of a cantilever structure.

[0037] For example, see Figure 1 , Figure 1 FIG. 1 is a schematic diagram of an installation structure of an object displacement monitoring device according to an embodiment of the present invention. Figure 1 As shown, in this embodiment, the object displacement monitoring device 1 is installed at the far end of the cantilever structure of the target object 2.

[0038] The present application installs an object displacement monitoring device 1 at a displacement sensitive point M, which can monitor the status of a structure or equipment, and accurately monitor and analyze the displacement sensitive point to obtain potential faults or abnormal conditions of the target object, thereby helping to improve the reliability, safety and efficiency of the target object.

[0039] According to an embodiment of the present invention, an embodiment of an object displacement monitoring device is provided. Figure 2 , Figure 2 is a schematic diagram of an object displacement monitoring device according to an embodiment of the present invention.

[0040] like Figure 2 As shown, the object displacement monitoring device 1 of the present application includes a camera module 11, a distance measuring module 12 and a processing module 13, wherein the camera module 11, the distance measuring module 12 and the processing module 13 are respectively connected to each other.

[0041] The camera module 11 is used to determine target position information of multiple target points, and send the target position information to the distance measurement module 12 and the processing module 13 .

[0042] The camera module 11 is a device with a camera function, such as a pan / tilt camera, a panoramic camera, a monocular camera, a multi-camera, etc.

[0043] In one implementation, the camera module 11 also includes an infrared observation mode. The infrared observation mode is used for nighttime observation to improve data collection accuracy.

[0044] Specifically, Figure 1 As shown, the camera module 11 is used to determine multiple target points on the non-target object 3, such as on a stable foundation or on adjacent buildings and structures, and ensure that the target point is a fixed point, and there is no obstacle between the target point and the camera module 11, obtain the target position information of each target point, and send the target position information to the ranging module 12 and the processing module 13. The number of target points is at least three.

[0045] In one implementation, the number of target points is three. The camera module 11 is used to detect the foundation, fixed buildings, fixed structures, etc. of non-target objects, and three target points that are not blocked by obstacles and are clear are determined. Further, the target position information of the three target points is determined. In a possible implementation, a surveyor performs precise measurement of the target points, and inputs the target position information of the target points into the embedded system of the camera module 11, and sends the target position information to the ranging module 12 and the processing module 13.

[0046] For example, Figure 1 As shown, the camera module 11 is installed at the displacement sensitive point M, and the camera module is used to determine the target point A, the target point B and the target point C on the foundation, and the target position information of the target point A is determined as (x 1 ,y 1 ,z 1 ), the target position information of target point B is (x 2,y 2 ,z 2 ) and the target position information of the target point C is (x 3 ,y 3 ,z 3 ), and (x 1 ,y 1 ,z 1 )、(x 2 ,y 2 ,z 2 )、(x 3 ,y 3 ,z 3 ) is sent to the ranging module 12 and the processing module 13.

[0047] In another implementation, the camera module 11 also includes a human body detection function.

[0048] Specifically, the camera module 11 performs human body detection on the shooting area to obtain a human body detection frame. When it is detected that the human body detection frame is close to the ranging path of the ranging module 12 or overlaps with the ranging path of the ranging module 12, the ranging module 12 is turned off.

[0049] Among them, the human body is detected to avoid harm to the human body by the monitoring device and improve the safety of monitoring.

[0050] The distance measuring module 12 is used to measure the target distance between the target point and the displacement sensitive point according to the target position information, and send the target distance to the processing module 13 .

[0051] The distance measuring module 12 is a device with a distance measuring function, such as a radar distance measuring device, a laser distance measuring device, etc.

[0052] Specifically, the ranging module 12 is a laser rangefinder. Specifically, the ranging device 12 is used to receive target position information, and laser pulses are emitted to the target point according to the target position information, and reflected laser is received, and the target distance between the displacement sensitive point M and the target point is determined based on the reflected laser, and the target distance is sent to the processing module 13.

[0053] In one implementation, the laser rangefinder emits a laser pulse to the target point according to the target position information. When the laser pulse encounters the target point, it will be reflected back. The laser rangefinder receives the reflected laser and accurately measures the flight time of the laser pulse from emission to reception. It calculates the target distance between the displacement sensitive point M and the target point according to the speed of light (c=299,792,458 m / s), and sends the target distance to the processing module 13.

[0054] In one implementation, the laser rangefinder emits a continuous wave or a modulated waveform, such as a sine wave laser beam. When the laser irradiates the target point and returns, a phase difference will be generated between the reflected light wave and the original emitted light wave due to the different path lengths. The target distance between the displacement sensitive point M and the target point is calculated by detecting the phase difference, and the target distance is sent to the processing module 13.

[0055] For example, Figure 1 As shown in the figure, the target distance between the displacement sensitive point M and the target point A is l using the laser rangefinder. 1 , the target distance between the displacement sensitive point M and the target point B is l 2 , the target distance between the displacement sensitive point M and the target point C is l 3 .

[0056] In one implementation, the distance measurement module 12 is provided with a collection frequency, collects a plurality of target data sets of target distances and corresponding collection times according to the collection frequency, and sends the target data sets to the processing module 13 .

[0057] For example, the collection frequency is every hour or every day.

[0058] The processing module 13 is used to determine the current position information of the displacement sensitive point M based on multiple target position information and corresponding target distances, and compare the current position information with the initial position information of the displacement sensitive point M to determine the displacement information of the target object 2.

[0059] The processing module 13 is a device with computing functions, such as a computer, a processor, etc.

[0060] Specifically, the processing module 13 receives the target position information of the target point and the target distance between the displacement sensitive point M and the target point. The target position information and the target distance are used for data fitting to determine the current position information of the unique displacement sensitive point M. Further, the processing module 13 obtains the initial position information of the displacement sensitive point M, compares the current position information with the initial position information, and determines the displacement direction, displacement distance and other information of the target object 2.

[0061] In one implementation, the triangulation principle is used to determine the current position information of the displacement sensitive point M. Specifically, a distance function between the displacement sensitive point M and the three target points is constructed:

[0062]

[0063] The current position information of the displacement sensitive point M is calculated to be (x, y, z).

[0064] Furthermore, the current position information (x, y, z) calculated by the above distance function is generally two results, namely the first position information and the second position information.

[0065] See also Figure 3 , Figure 3 FIG. 1 is a schematic diagram of a current position determination method according to an embodiment of the present invention. Figure 3 As shown, the distance from the target point A is l 1 And the distance from the target point B is l 2 The set of points is a circle in space, and the distance from the target point C is l 3 The set of points is a sphere in space. Generally, the circle has two intersection points with the sphere. The present application compares the first position information, the second position information and the initial position information to determine the current position information.

[0066] Among them, the position detection result is a three-dimensional coordinate, which is convenient for the subsequent analysis of the displacement status of the target object in three dimensions. At the same time, the position of the displacement sensitive point is automatically monitored by using the three-point positioning method, which can improve the accuracy of position detection.

[0067] In one implementation, the position information closest to the initial position information is selected as the current position information, wherein the initial position information is obtained by calculation using the target point when the object displacement monitoring device is installed.

[0068] Specifically, a first distance between the first position information and the initial position information is calculated; a second distance between the second position information and the initial position information is calculated; when the first distance is less than the second distance, the first position information is used as the current position information; when the second distance is less than the first distance, the second position information is used as the current position information.

[0069] In one implementation, when the target point is a point on the ground, position information with a positive value is used as the current position information.

[0070] Among them, an analysis and judgment method for multiple position results is proposed, and the calculated position information is compared with the initial position information to further accurately determine the current position information, realize automatic error detection, save manpower and reduce costs.

[0071] In another implementation, there are four target points, of which three target points A, B, and C are positioning points, and another target point D is a verification point. The above implementation is used to determine the current position information of the displacement sensitive point M using the positioning points A, B, and C. The processing module 13 is used to calculate the test distance between the current position information and the verification point D, and the test distance is compared with the target distance of the verification point D detected by the distance measurement module 12. When the distance difference is less than or equal to the preset distance, the calculation result is accurate. When the distance difference is greater than the preset distance, the distance measurement detection is performed again.

[0072] Among them, by selecting a fourth or more fixed points as calibration points and calibrating the measurement data and results, the reliability of the monitoring device can be increased.

[0073] Further, the displacement information of the displacement sensitive point M is determined.

[0074] In one implementation, the processing module 13 of the present application determines the moving angle and moving direction of the displacement sensitive point M according to the current position information and the initial position information.

[0075] In another implementation, the processing module 13 of the present application determines the displacement trend of the displacement sensitive point M according to the current position information and the initial position information.

[0076] Specifically, the processing module 13 receives multiple sets of target data sets from the ranging module 12, and determines the position information of the displacement sensitive point M and the position data set of the corresponding acquisition time based on the target position information and the historical position information in the multiple sets of target data sets, and determines the displacement trend of the target position 2 in combination with the initial position information and the corresponding initial time of the displacement sensitive point M.

[0077] Exemplarily, the processing module 13 calculates the movement curve of the displacement sensitive point M, and analyzes the movement curve to determine the deformation trend of the target object 2 for safety assessment.

[0078] Among them, the displacement of objects is continuously monitored and the displacement trend is analyzed to facilitate the safety assessment of the object displacement and improve availability.

[0079] Furthermore, when the displacement exceeds a preset displacement, an early warning is issued.

[0080] In this implementation, the present application installs an object displacement monitoring device at a displacement sensitive point, with fewer devices to be arranged, no major structural modifications are required, and the installation is convenient, which can reduce the monitoring cost. At the same time, the target point is determined by the object displacement monitoring device, and the displacement of the target object is determined by the selected target point. The target point can be determined according to the structural position of the target object, and different target objects can be adaptively monitored, further improving the pertinence of monitoring and improving the monitoring accuracy.

[0081] According to an embodiment of the present invention, another embodiment of an object displacement monitoring device is provided. Figure 4 , Figure 4 is a schematic diagram of another object displacement monitoring device according to an embodiment of the present invention.

[0082] like Figure 4 As shown, Figure 2 Compared with the object displacement monitoring device shown in FIG. 1 , the object displacement monitoring device 1 of this embodiment further includes a focusing module 14 , wherein the focusing module 14 is connected to the camera module 11 .

[0083] The camera module 14 is also used to rotate according to the target position information and align the directions of multiple target points. The focus module 14 is used to adjust the focal length of the camera module 11 until the camera module 11 captures multiple target points.

[0084] Specifically, after the camera module 11 determines the target position information of the multiple target points, the camera module 11 adjusts the lens to be aligned with the directions of the multiple target points, and uses the focusing module 14 to focus.

[0085] For example, see Figure 1 The camera module 11 is aimed at the target point A, the focusing module 14 focuses on the target point A, and the distance measurement module 12 measures the target distance l between the displacement sensitive point M and the target point A. 1 The camera module 11 is aimed at the target point B, the focus module 14 focuses on the target point B, and the distance measuring module 12 measures the target distance l between the displacement sensitive point M and the target point B 2 The camera module 11 is aimed at the target point C, the focus module 14 focuses on the target point C, and the distance measuring module 12 measures the target distance l between the displacement sensitive point M and the target point C 3 .

[0086] Among them, providing the focusing module 14 can improve the accuracy of target point position detection.

[0087] The object displacement monitoring device 1 of this embodiment further includes a data storage module 15 , and the data storage module 15 is connected to the camera module 11 , the distance measurement module 12 and the processing module 13 respectively.

[0088] The data storage module 15 is used to store the target position information of the target point, the target distance between the target point and the dry point of the displacement surface, the initial position information of the displacement sensitive point M, the historical position information, and the current position information.

[0089] Specifically, after the camera module 11 determines the target position information of multiple target points, the target position information is sent to the data storage module 15. After the ranging module 12 measures the target distance, the target distance is sent to the data storage module 15. After the processing module 13 obtains the initial position information, historical position information, and current position information, the initial position information, historical position information, and current position information are sent to the data storage module 15.

[0090] The object displacement monitoring device 1 of this embodiment further includes a wireless transmission module 16 , and the wireless transmission module 16 is connected to the data storage module 15 .

[0091] The wireless transmission module 16 is used to transmit the data stored in the data storage module 15 to the user end.

[0092] The object displacement monitoring device 1 of this embodiment further includes a power supply module (not shown in the figure), which is respectively connected to the camera module 11, the distance measurement module 12, the processing module 13, the focus module 14, the data storage module 15 and the wireless transmission module 16.

[0093] The power supply module is used to supply power to the camera module 11 , the distance measuring module 12 , the processing module 13 , the focusing module 14 , the data storage module 15 and the wireless transmission module 16 .

[0094] According to an embodiment of the present invention, an embodiment of a method for monitoring the displacement of an object is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0095] In this embodiment, a method for monitoring the displacement of an object is provided, which can be used in the above-mentioned object displacement monitoring device. Figure 5 is a flow chart of a method for monitoring object displacement according to an embodiment of the present invention. It should be noted that if there are substantially the same results, this embodiment does not necessarily use Figure 5 The process sequence shown is limited.

[0097] Step S502: measure the target distance between the target point and the displacement sensitive point respectively according to the target position information, and send the target distance to the processing module.

[0098] Step S503: determining the current position information of the displacement sensitive point based on the multiple target position information and the corresponding target distances, and comparing the current position information with the initial position information of the displacement sensitive point to determine the displacement information of the target object.

[0100] In this implementation, the present application installs an object displacement monitoring device at a displacement sensitive point, with fewer devices to be arranged, no major structural modifications are required, and the installation is convenient, which can reduce the monitoring cost. At the same time, the target point is determined by the object displacement monitoring device, and the displacement of the target object is determined by the selected target point.
