Description

Technical Field

[0001] The present application relates to the technical field of deformation monitoring, and in particular to a deformation monitoring device and a monitoring method. Background Art

[0002] At present, deformation monitoring is the work of continuously observing the deformation phenomenon of the deformable body, analyzing the deformation morphology of the deformable body, and predicting the development trend of the deformation of the deformable body. Deformation monitoring includes establishing a deformation monitoring network to monitor horizontal displacement, settlement, tilt, cracks, deflection, swing and vibration.

[0003] In the prior art, deformation monitoring is generally carried out by manual observation or measurement by measuring robots. Among them, manual observation requires manual operation of instruments for observation; manual observation cannot achieve real-time observation and is also very costly. Although the use of measuring robots for measurement can achieve real-time high-precision measurement, the cost of measuring robots is high, and the positions that a measuring robot can monitor are limited. For occasions with more monitoring positions, a large number of measuring robots need to be invested, which is very costly and is particularly unsuitable for large-scale promotion and use.

[0004] Therefore, how to improve the existing deformation monitoring method to overcome the above-mentioned deficiencies is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

Then the displacement of the deformable body along the X-axis direction is ΔX=(X1-X2+ΔY)*tanβ.

[0007] Preferably, the angle α is 45°.

[0008] Preferably, the angle β is 45°.

[0009] Preferably, the angle α is between 30° and 60°.

[0010] Preferably, the angle β is between 30° and 60°.

[0011] Preferably, the step of obtaining the Y-axis displacement includes: uploading Y1 and Y2 measured by the first distance measuring component to the early warning platform by using a communication module, and the early warning platform calculates and outputs the displacement ΔY.

[0012] Preferably, the step of obtaining the Z-axis displacement includes: uploading Z1 and Z2 measured by the second ranging component to the early warning platform by using a communication module, and the early warning platform calculates and outputs the displacement ΔZ.

[0013] Preferably, the step of obtaining the X-axis displacement includes: uploading X1 and X2 measured by the third distance measuring component to the early warning platform by using a communication module, and the early warning platform calculates and outputs the displacement ΔX.

[0014] The present application also provides a deformation monitoring device for the above deformation detection method, comprising: A target, the target is mounted on the deformable body to be monitored, and the target is provided with a first substrate, a second substrate and a third substrate; the first substrate is parallel to the XZ plane; the second substrate is perpendicular to the YZ plane, and an angle α is formed between the second substrate and the XY plane; the third substrate is perpendicular to the XY plane, and an angle β is formed between the third substrate and the YZ plane; A first distance measuring component, the first distance measuring component is arranged along the Y-axis direction, and the first distance measuring component is used to measure a first distance between the first distance measuring component and the first substrate; A second distance measuring component, the second distance measuring component is arranged along the Y-axis direction, and the second distance measuring component is used to measure a second distance between the second distance measuring component and the second substrate; A third distance measuring component, the third distance measuring component is arranged along the Y-axis direction, and the third distance measuring component is used to measure a third distance between the third distance measuring component and the third substrate; A communication module and an early warning platform, wherein the communication module is used to transmit the first spacing, the second spacing and the third spacing to the early warning platform, and the early warning platform is used to calculate and output the displacement ΔY, the displacement ΔZ and the displacement ΔX.

[0015] Preferably, the first substrate, the second substrate and the third substrate are arranged at intervals along the Z-axis direction.

[0016] Preferably, the deformation monitoring device further comprises a support for mounting the first ranging assembly, the second ranging assembly and the third ranging assembly.

[0017] Preferably, the support member includes a mounting frame, a rotating frame and a fixed frame; the mounting frame is used to mount the first ranging assembly, the second ranging assembly and the third ranging assembly, the mounting frame is rotatably connected to the rotating frame, the rotation axis of the mounting frame is parallel to the X-axis, and the mounting frame can stop rotating when it rotates to any position relative to the rotating frame; the rotating frame is rotatably connected to the fixed frame, the rotation axis of the rotating frame is parallel to the Z-axis, and the rotating frame can stop rotating when it rotates to any position relative to the fixed frame.

[0018] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention installs a target on the deformable body to be monitored, and sets a first substrate, a second substrate, and a third substrate with a specific position relationship on the target. Since the first distance measuring component is set along the Y-axis direction, and the first substrate is parallel to the XZ plane, the displacement of the deformable body along the Z-axis direction and the X-axis direction will not cause the distance between the first distance measuring component and the first substrate to change; when the deformable body is displaced along the +Y-axis direction, the distance between the first distance measuring component and the first substrate will increase; conversely, when the deformable body is displaced along the -Y-axis direction, the distance between the first distance measuring component and the first substrate will decrease; therefore, the first distance measuring component can be used to measure the distance between the first distance measuring component and the first substrate at the first moment and the second moment along the Y-axis direction. When the first moment and the second moment are Y1 and Y2 respectively, the displacement of the deformable body along the Y-axis direction in the time interval from the first moment to the second moment ΔY=Y2-Y1, wherein the displacement ΔY is a negative value, which indicates displacement along the -Y-axis direction, and a positive value, which indicates displacement along the +Y-axis direction.

[0019] (2) When the deformable body is displaced along the +Z axis, the distance between the second distance measuring component and the second substrate will decrease; conversely, when the deformable body is displaced along the -Z axis, the distance between the second distance measuring component and the second substrate will increase; and when the deformable body is displaced along the +Y axis, the distance between the second distance measuring component and the second substrate will increase; conversely, when the deformable body is displaced along the -Y axis, the distance between the second distance measuring component and the second substrate will decrease; therefore, when considering measuring the displacement of the deformable body along the Z axis, it is necessary to eliminate the influence of the displacement of the deformable body along the Y axis. Then, the displacement of the deformable body along the Z axis ΔZ = (Z1-Z2+ΔY)*tanα, where a negative value of the displacement ΔZ indicates displacement along the -Z axis, and a positive value indicates displacement along the +Z axis.

[0020] (3) When the deformable body is displaced along the +X axis direction, the distance between the third distance measuring component and the third substrate will decrease; conversely, when the deformable body is displaced along the -X axis direction, the distance between the third distance measuring component and the third substrate will increase; and when the deformable body is displaced along the +Y axis direction, the distance between the second distance measuring component and the second substrate will increase; conversely, when the deformable body is displaced along the -Y axis direction, the distance between the second distance measuring component and the second substrate will decrease; therefore, when considering measuring the displacement of the deformable body along the X axis direction, it is necessary to eliminate the influence of the displacement of the deformable body along the Y axis direction, and the displacement of the deformable body along the X axis direction ΔX = (X1-X2+ΔY)*tanβ; wherein, a negative value of the displacement ΔX indicates a displacement along the -X axis direction, and a positive value indicates a displacement along the +X axis direction.

[0021] In summary, the present application uses a target with a first substrate, a second substrate and a third substrate, and cooperates with a first distance measuring component, a second distance measuring component and a third distance measuring component to measure, so as to obtain the displacement of the deformable body along the three dimensions of the X axis, the Y axis and the Z axis, thereby realizing real-time automatic deformation monitoring, and there is no need to re-target after the target moves. Compared with the existing measurement robot, the deformation monitoring device has a simple structure, a small size and a low cost, and is particularly suitable for large-scale promotion and use.

[0033] Embodiment 1

[0034] Reference Figures 1 to 6 , this embodiment provides a deformation monitoring method, comprising the following steps: Preparation step: installing a target 1 with a first substrate 11, a second substrate 12 and a third substrate 13 on a deformable body to be monitored; wherein the first substrate 11 is parallel to the XZ plane; the second substrate 12 is perpendicular to the YZ plane, and an angle α is formed between the second substrate 12 and the XY plane; the third substrate 13 is perpendicular to the XY plane, and an angle β is formed between the third substrate 13 and the YZ plane; Obtaining the Y-axis displacement: using the first distance measuring component 2 to measure the distance between the first distance measuring component 2 and the first substrate 11 along the Y-axis direction at the first moment and the second moment, the distance between the first distance measuring component 2 and the first substrate 11 is Y1 and Y2 respectively, then the displacement of the deformable body along the Y-axis direction ΔY=Y2-Y1; Obtaining the Z-axis displacement: using the second distance measuring component 3 to measure the distance between it and the second substrate 12 along the Y-axis direction at the first moment and the second moment, the distance is Z1 and Z2 respectively, then the displacement of the deformable body along the Z-axis direction ΔZ = (Z1-Z2+ΔY)*tanα; Obtain the X-axis displacement: Use the third distance measuring component 4 to measure the distance between it and the third substrate 13 along the Y-axis direction at the first moment and the second moment, respectively X1 and X2, then the displacement of the deformable body along the X-axis direction ΔX = (X1-X2+ΔY)*tanβ.

[0035] Working principle: Figure 2As shown, by installing a target 1 on the deformable body to be monitored, and by setting a first substrate 11, a second substrate 12 and a third substrate 13 with a specific position relationship on the target 1. Figure 2 and Figure 3 Since the first distance measuring component 2 is arranged along the Y-axis direction and the first substrate 11 is parallel to the XZ plane, the displacement of the deformable body along the Z-axis direction and the X-axis direction will not cause the distance between the first distance measuring component 2 and the first substrate 11 to change; and since when the deformable body is displaced along the +Y-axis direction, the distance between the first distance measuring component 2 and the first substrate 11 will increase; conversely, when the deformable body is displaced along the -Y-axis direction, the distance between the first distance measuring component 2 and the first substrate 11 will decrease; therefore, when the first distance measuring component 2 is used to measure the spacing between it and the first substrate 11 at the first moment and the second moment along the Y-axis direction, the displacement ΔY of the deformable body in the time interval from the first moment to the second moment along the Y-axis direction is Y1 and Y2 respectively, wherein a negative value of the displacement ΔY indicates a displacement along the -Y-axis direction, and a positive value indicates a displacement along the +Y-axis direction. It can be understood that the reason why Y2-Y1 is used is to make the positive and negative values ​​of the displacement ΔY correspond to the positive and negative directions of the Y axis respectively, so as to facilitate the intuitive display of the displacement direction.

[0036] Combination Figure 2 and Figure 3 When the deformable body is displaced along the +Z axis direction, under the action of the angle α, the signal emitted by the second ranging component 3 will be reflected back from the second substrate 12 earlier, thereby causing the distance between the second ranging component 3 and the second substrate 12 to decrease; conversely, when the deformable body is displaced along the -Z axis direction, the signal emitted by the second ranging component 3 will be reflected back from the second substrate 12 later, thereby causing the distance between the second ranging component 3 and the second substrate 12 to increase. Furthermore, when the deformable body is displaced along the +Y axis direction, the distance between the second distance measuring component 3 and the second substrate 12 will also increase by the same amount; conversely, when the deformable body is displaced along the -Y axis direction, the distance between the second distance measuring component 3 and the second substrate 12 will decrease by the same amount; therefore, when considering measuring the displacement of the deformable body along the Z axis direction, it is necessary to eliminate the influence of the displacement of the deformable body along the Y axis direction, so the displacement of the deformable body along the Z axis direction ΔZ=(Z1-Z2+ΔY)*tanα, wherein a negative value of the displacement ΔZ indicates displacement along the -Z axis direction, and a positive value indicates displacement along the +Z axis direction. It can be understood that the reason for using Z1-Z2 is to make the positive and negative values ​​of the displacement ΔZ correspond to the positive and negative directions of the Z axis, respectively, so as to facilitate intuitive display of the displacement direction.

[0037] like Figure 4As shown, when the deformable body moves along the +X axis direction, the signal emitted by the third distance measuring component 4 will be reflected back from the third substrate 13 earlier, thereby causing the distance between the third distance measuring component 4 and the third substrate 13 to decrease; conversely, when the deformable body moves along the -X axis direction, the signal emitted by the third distance measuring component 4 will be reflected back from the third substrate 13 later, thereby causing the distance between the third distance measuring component 4 and the third substrate 13 to increase. Figure 2 and Figure 3 , and because when the deformable body is displaced along the +Y axis direction, the distance between the second distance measuring component 3 and the second substrate 12 will increase equally; conversely, when the deformable body is displaced along the -Y axis direction, the distance between the second distance measuring component 3 and the second substrate 12 will decrease equally; therefore, when considering measuring the displacement of the deformable body along the X axis direction, it is necessary to eliminate the influence of the displacement of the deformable body along the Y axis direction, and the displacement of the deformable body along the X axis direction ΔX=(X1-X2+ΔY)*tanβ; wherein, a negative value of the displacement ΔX indicates a displacement along the -X axis direction, and a positive value indicates a displacement along the +X axis direction. It can be understood that the reason for using X1-X2 is to make the positive and negative values ​​of the displacement ΔX correspond to the positive and negative directions of the X axis, respectively, so as to facilitate the intuitive display of the displacement direction.

[0038] The following is a specific description of the displacement of the deformed body in the +Y axis direction ΔY as an example: Figure 5 and Figure 6 As shown, for the first ranging component 2, Y1 is the distance between the first ranging component 2 and the corresponding initial reflection point, and Y2 is the distance between the first ranging component 2 and the corresponding displacement reflection point. Then, the displacement of the deformable body along the Y-axis direction is ΔY=Y2-Y1, and ΔY is a positive value, which means displacement along the +Y-axis direction.

[0039] like Figure 5 As shown, for the second distance measuring component 3, Z1 is the distance between the second distance measuring component 3 and the corresponding initial reflection point, and Z2 is the distance between the second distance measuring component 3 and the corresponding reflection point after displacement, then ΔZ=(Z1-Z2+ΔY)*tanα. Among them, since Z1-Z2 is a negative value, and the absolute value of Z1-Z2 is equal to the absolute value of Y2-Y1, the displacement of the deformable body along the Z-axis direction ΔZ=(Z1-Z2+ΔY)*tanα=0, that is, the deformable body has no displacement along the Z-axis direction.

[0040] like Figure 6As shown, for the third distance measuring component 4, X1 is the distance between the third distance measuring component 4 and the corresponding initial reflection point, and X2 is the distance between the third distance measuring component 4 and the corresponding displacement reflection point, then ΔX=(X1-X2+ΔY)*tanβ. Similarly, since X1-X2 is a negative value, and the absolute value of X1-X2 is equal to the absolute value of Y2-Y1, the displacement of the deformable body along the X-axis direction ΔX=(X1-X2+ΔY)*tanβ=0, that is, the deformable body has no displacement along the X-axis direction.

[0041] That is to say, by using the target 1 with the first substrate 11, the second substrate 12 and the third substrate 13, and cooperating with the first distance measuring component 2, the second distance measuring component 3 and the third distance measuring component 4 to achieve measurement, the displacement of the deformable body along the three dimensions of the X axis, the Y axis and the Z axis can be obtained, thereby achieving real-time automatic deformation monitoring, and there is no need to re-target after the target 1 moves. Compared with the existing measurement robot, the deformation monitoring device has a simple structure, small size and low cost, and is particularly suitable for large-scale promotion and use.

[0042] In this embodiment, the angle α and the angle β are preferably 30° to 60°, and the most preferred value is 45°. When the value is 45°, tanα and tanβ are both equal to 1, and the calculation is simpler.

[0043] In this embodiment, if Figure 7 As shown, the step of obtaining the Y-axis displacement includes: using the communication module 5 to upload Y1 and Y2 measured by the first distance measuring component 2 to the early warning platform 6, and the early warning platform 6 calculates and outputs the displacement ΔY.

[0044] In this embodiment, if Figure 7 As shown, the step of obtaining the Z-axis displacement includes: uploading Z1 and Z2 measured by the second distance measuring component 3 to the early warning platform 6 by using the communication module 5, and the early warning platform 6 calculates and outputs the displacement ΔZ.

[0045] In this embodiment, if Figure 7 As shown, the step of obtaining the X-axis displacement includes: uploading X1 and X2 measured by the third distance measuring component 4 to the early warning platform 6 by using the communication module 5, and the early warning platform 6 calculates and outputs the displacement ΔX.

[0046] Embodiment 2

[0047] Reference Figures 1 to 4 Based on the deformation monitoring method of the first embodiment, this embodiment provides a deformation monitoring device, including a target 1, a first distance measuring component 2, a second distance measuring component 3, a third distance measuring component 4, a communication module 5 and an early warning platform 6. The target 1 is installed on the deformable body to be monitored, and a first substrate 11, a second substrate 12 and a third substrate 13 are provided on the target 1.

[0048] The first substrate 11 is parallel to the XZ plane; the second substrate 12 is perpendicular to the YZ plane, and an angle α is formed between the second substrate 12 and the XY plane; the third substrate 13 is perpendicular to the XY plane, and an angle β is formed between the third substrate 13 and the YZ plane.

[0049] It should be noted that, under the premise that the first substrate 11, the second substrate 12 and the third substrate 13 meet the above relationship, the relative positions of the first substrate 11, the second substrate 12 and the third substrate 13 on the target 1 can be adjusted arbitrarily. In this embodiment, the first substrate 11, the second substrate 12 and the third substrate 13 are preferably arranged at intervals along the Z-axis direction (it is sufficient to keep the intervals along the axis direction, and the positions can also be arbitrary, such as Figure 2 As shown, along the +Z axis direction are the third substrate 13, the first substrate 11 and the second substrate 12).

[0050] The first distance measuring component 2 is arranged along the Y-axis direction, and the first distance measuring component 2 is used to measure the first distance between it and the first substrate 11. The second distance measuring component 3 is arranged along the Y-axis direction, and the second distance measuring component 3 is used to measure the second distance between it and the second substrate 12. The third distance measuring component 4 is arranged along the Y-axis direction, and the third distance measuring component 4 is used to measure the third distance between it and the third substrate 13. The communication module 5 is used to transmit the first distance, the second distance and the third distance to the early warning platform 6, and the early warning platform 6 calculates and outputs the displacement ΔY, the displacement ΔZ and the displacement ΔX.

[0051] Reference Figure 1 In this embodiment, in order to facilitate the unified installation of the first ranging component 2, the second ranging component 3 and the third ranging component 4, the deformation monitoring device also includes a support member 7 for installing the first ranging component 2, the second ranging component 3 and the third ranging component 4.

[0052] It should be understood that the present application does not limit the specific structure of the support member 7, and only a specific structure is provided below for reference: Figure 8As shown, the support member 7 includes a mounting frame 71, a rotating frame 72 and a fixed frame (the fixed frame is not shown in the attached figure); the mounting frame 71 is used to install the first distance measuring component 2, the second distance measuring component 3 and the third distance measuring component 4, the mounting frame 71 is rotatably connected to the rotating frame 72, the rotation axis of the mounting frame 71 is parallel to the X axis, and the mounting frame 71 can stop rotating when it rotates to any position relative to the rotating frame 72; the rotating frame 72 is rotatably connected to the fixed frame, the rotation axis of the rotating frame 72 is parallel to the Z axis, and the rotating frame 72 can stop rotating when it rotates to any position relative to the fixed frame. By rotating and adjusting the mounting frame 71 and the rotating frame 72, the positions of the first distance measuring component 2, the second distance measuring component 3 and the third distance measuring component 4 can be adjusted, so as to facilitate installation and positioning during the actual installation process. Among them, it can be understood that the rotation installation methods between the mounting frame 71 and the rotating frame 72 and between the rotating frame 72 and the fixed frame are all prior art and will not be described in detail here.

[0053] It should be noted that the first ranging component 2, the second ranging component 3, the third ranging component 4, the communication module 5 and the early warning platform 6 themselves and the electrical connection or wireless transmission method therebetween are all existing technologies and will not be described in detail here.

[0054] It should be understood that in some embodiments of the present application, in actual operation, when the XY plane is arranged horizontally and there may be a height difference between the point to be monitored and the observation point, at this time, it may cause the first ranging component 2, the second ranging component 3 and the third ranging component 4 to be difficult or impossible to be arranged along the Y-axis direction. In this case, the first ranging component 2, the second ranging component 3 and the third ranging component 4 can also be set to have a certain angle with the Y-axis (the specific angle depends on the actual environment of the site). At this time, the coordinates of the point to be monitored and the observation point in the horizontal coordinate system can be first measured, and then the measured offset value can be converted into the offset in the horizontal coordinate system through coordinate system conversion.

Those skilled in the art should understand that the present application is not limited by the above embodiments.
