[0045] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0046] In view of the above-mentioned defects of the prior art, the present invention provides a tunnel deformation monitoring system, method and medium. Figure 1 shows a block diagram of a tunnel deformation monitoring system according to an embodiment of the present invention, Figure 2FIG. 4 shows a block diagram of a tunnel deformation monitoring system according to another embodiment of the present invention. Figure 1 and Figure 2 As shown, the system includes: a number of monitoring instruments 100 and a determination module 200 connected via a communication module 300;

[0047] like Figure 3 As shown, a plurality of monitoring instruments 100 are distributed and arranged at each section of the tunnel, one of the plurality of monitoring instruments 100 is used as a first monitoring instrument, and the others are used as second monitoring instruments, for obtaining a first distance between each monitoring instrument and a target point in the tunnel, a second distance between the first monitoring instrument and the second monitoring instrument, and a target angle;

[0048] The determination module 200 is used to determine whether the tunnel is deformed according to the first distance, the second distance and the target angle, and to determine the deformation amount of the tunnel when the tunnel is deformed.

[0049] Among them, a plurality of monitoring instruments 100 can be set at any position of each section in the tunnel, and a plurality of monitoring instruments 100 can communicate with each other through a mesh network. A target point can be set at any position of each section of the tunnel.

[0050] The present invention is composed of a plurality of monitoring instruments and a determination module. The plurality of monitoring instruments obtain a first distance between the monitoring instruments and a target point in a tunnel, a second distance between the monitoring instruments, and a target angle. Then, the determination module determines whether the tunnel is deformed according to the first distance, the second distance, and the target angle. In this way, the deformation of each section of the tunnel is automatically detected, the accuracy of the detection result is improved, the efficiency of tunnel deformation detection is improved, and the safety of the tunnel is improved.

[0051] like Figure 2 As shown, the monitoring instrument 100 includes: a deformation measurement module 110 and a position detection module 120;

[0052] The deformation measurement module 110 is used to obtain a first initial distance between the monitoring instrument and the target point at the current moment and a first real-time distance between the monitoring instrument and the target point at a preset time after the current moment;

[0053] The position detection module 120 is used to obtain the second initial distance and the first target angle between the first monitoring instrument and the second monitoring instrument at the current moment, and the second real-time distance and the second target angle between the first monitoring instrument and the second monitoring instrument for a preset time after the current moment.

[0054] The deformation measurement module 110 may include: an array laser, and the position detection module 120 may include: a millimeter wave radar. The first distance may include: a first initial distance and a first real-time distance; the second distance may include: a second initial distance and a second real-time distance; and the target angle may include a first target angle and a second target angle.

[0055] For example, there may be n target points. The first distance set between the n target points and the monitoring instrument can be obtained by the array laser, as shown in Formula 1:

[0056] S it =(x1,x2,…,x n ) Formula 1

[0057] In formula 1, S it Refers to the first distance set; i refers to the section number, and i = 1, 2, ..., m; t refers to the acquisition time interval, min. n Refers to the first distance between n target points and the monitoring instrument.

[0058] The current time t = 0. For example, the preset time length may be determined according to the actual scenario, and the present invention sets it to 10 minutes, that is, t = 10. In this way, the first initial distance and the first real-time distance between each monitoring instrument and the target point can be obtained.

[0059] Similarly, the millimeter wave radar can also be used to obtain the second initial distance and the first target angle between the first monitoring instrument and the second monitoring instrument at t=0, and the second real-time distance and the second target angle between the first monitoring instrument and the second monitoring instrument at t=10.

[0060] In addition, the wavelength of millimeter-wave radar is usually in the range of 1 to 10 mm, which is between microwaves and centimeter waves. It is less affected by environmental interference and uses FMCW continuous sawtooth wave modulation. It can simultaneously detect the location information of multiple monitoring instruments, including distance and angle.

[0061] In this way, the monitoring instrument is composed of the deformation measurement module 110 and the position detection module 120, which realizes the acquisition of the first distance, the second distance and the target angle, and provides a basis for determining whether the tunnel is deformed.

[0062] like Figure 2 As shown, the determination module 200 includes: a first determination module 210 and a second determination module 220;

[0063] A first determination module 210, connected to the deformation measurement module 110, is used to determine whether radial deformation occurs in the tunnel according to the first initial distance and the first real-time distance;

[0064] The second determination module 220 is connected to the position detection module 120, and is used to determine whether the tunnel has longitudinal deformation according to the second initial distance, the second real-time distance, the first target angle and the second target angle.

[0065] Among them, the longitudinal deformation of the tunnel can be determined by comparing the changes in the distance and angle between the monitoring instruments; the radial deformation of the tunnel can also be determined by comparing the positional relationship between each target point and the monitoring instrument.

[0066] In this way, the determination module 200 is composed of the first determination module 210 and the second determination module 220, which realizes the detection of whether radial deformation and longitudinal deformation occur in the tunnel, and improves the accuracy of deformation detection.

[0067] In a possible embodiment, the first determination module 210 includes: a first determination submodule and a second determination submodule;

[0068] A first determination submodule, configured to determine that radial deformation of the tunnel occurs if the first initial distance is not equal to the first real-time distance;

[0069] The second determination submodule is used to determine that no radial deformation occurs in the tunnel if the first initial distance is equal to the first real-time distance.

[0070] Among them, whether the tunnel has radial deformation can be determined by whether the first initial distance is equal to the first real-time distance. In this way, whether the tunnel has radial deformation can be accurately determined, thereby improving the accuracy of radial deformation.

[0071] In a possible embodiment, the second determination module 220 includes: a third determination submodule and a fourth determination submodule;

[0072] A third determination submodule, configured to determine that the tunnel has undergone longitudinal deformation if the second initial distance is not equal to the second real-time distance and / or the first target angle is not equal to the second target angle;

[0073] The fourth determination submodule is used to determine that no longitudinal deformation occurs in the tunnel if the second initial distance is equal to the second real-time distance and the first target angle is equal to the second target angle.

[0074] The distances measured between the monitoring instruments can be used as a calibration standard. For example, when the error between the distance measured by the first monitoring instrument and the second monitoring instrument and the distance measured by the second monitoring instrument and the first monitoring instrument is less than the allowable error ε, it indicates that the accuracy meets the requirement. For example, the allowable error can be determined according to the actual scenario, and the present invention is not limited here.

[0075] In addition, whether the tunnel has undergone longitudinal deformation can be determined by determining whether the second initial distance is equal to the second real-time distance and whether the first target angle is equal to the second target angle. In this way, whether the tunnel has undergone longitudinal deformation can be accurately determined, thereby improving the accuracy of longitudinal deformation.

[0076] like Figure 2 As shown, the determination module 200 also includes: a third determination module 230, which is connected to the first determination module 210 and the second determination module 220, and is used to determine the initial position of the target point at the current moment according to the first initial distance, the second initial distance and the first target angle when the tunnel is deformed; and determine the real-time position of the target point for a preset time after the current moment according to the first real-time distance, the second real-time distance and the second target angle; and determine the deformation amount of the tunnel according to the initial position and the real-time position.

[0077] For example, a coordinate system is established with the first monitoring instrument as the origin. Then, based on the second initial distance and the first target angle, the initial coordinates of the second monitoring instrument can be obtained through Formula 2; based on the second real-time distance and the second target angle, the real-time coordinates of the second monitoring instrument can be obtained through Formula 2.

[0078]

[0079] Wherein, (x2, y2, z2) refers to the coordinates of the second monitoring instrument; (x1, y1, z1) refers to the coordinates of the first monitoring instrument; l refers to the second distance; θ xz ,θ xy Refers to the target angle.

[0080] Next, the initial position of the target point can be determined based on the first initial distance between the monitoring instruments 100 and the target point; the real-time position of the target point can also be determined based on the first real-time distance between the monitoring instruments 100 and the target point. After that, the radial deformation of the tunnel can be calculated by subtracting the horizontal coordinates of the initial position and the real-time position; the longitudinal deformation of the tunnel can also be calculated by subtracting the vertical coordinates of the initial position and the real-time position.

[0081] In addition, the origin can also be other points, such as Figure 4 shown.

[0082] In this way, the deformation of the tunnel can be calculated accurately, which improves the accuracy of deformation calculation.

[0083] In a possible embodiment, the system further includes: a display module 400 connected to the determination module 200, and configured to perform interpolation calculations based on the first distance, the second distance, and the target angle, respectively, to generate a distribution diagram of tunnel deformation results.

[0084] like Figure 5As shown, when there are intersections such as inclined shafts in the tunnel that cannot be measured directly, measurements can be made through nearby monitoring instruments. Interpolation calculations can also be performed based on the first distance, the second distance, and the target angle to obtain the tunnel deformation in the unmonitored area, thereby generating a distribution map of the tunnel deformation results. Specifically, the cubic spline interpolation method can be used for interpolation to avoid the Runge phenomenon.

[0085] In this way, the deformation result distribution map of the entire tunnel can be obtained, which improves the comprehensiveness of tunnel monitoring.

[0086] According to another aspect of the present invention, a tunnel deformation monitoring method is also provided, which is performed by a tunnel deformation monitoring system, the system comprising: a plurality of monitoring instruments 100 and a determination module 200 connected via a communication module 300; one of the plurality of monitoring instruments 100 is used as a first monitoring instrument, and the others are used as second monitoring instruments; Figure 6 A flow chart of a tunnel deformation monitoring method according to an embodiment of the present invention is shown, the method comprising:

[0087] S101, obtaining a first distance between each monitoring instrument and a target point in the tunnel, a second distance between the first monitoring instrument and the second monitoring instrument, and a target angle;

[0088] S102, determining whether the tunnel is deformed according to the first distance, the second distance and the target angle;

[0089] S103, when the tunnel is deformed, determining the deformation amount of the tunnel.

[0090] The tunnel deformation monitoring method provided by the present invention can also be used in conjunction with a computer-readable storage medium, on which a computer program is stored, and the computer program is executed to run a tunnel deformation monitoring method. The computer program can run computer instructions, which include computer program codes, which can be in source code form, object code form, executable file or some intermediate form.

[0091] Computer-readable storage media may include: any entity or device that can carry computer program code, recording media, USB flash drives, mobile hard disks, magnetic disks, optical disks, computer memory, read-only memory (ROM), random access memory (RAM), electrical carrier signals, telecommunication signals, and software distribution media, etc.

[0092] It should be noted that the content contained in computer-readable storage media can be appropriately increased or decreased based on the requirements of legislation and patent practices in the jurisdiction. For example, in some jurisdictions, based on legislation and patent practices, computer-readable storage media do not include electrical carrier signals and telecommunications signals.

[0094] The present invention is composed of a plurality of monitoring instruments and a determination module. The plurality of monitoring instruments obtain a first distance between the monitoring instruments and a target point in a tunnel, a second distance between the monitoring instruments, and a target angle.

In this way, the deformation of each section of the tunnel is automatically detected, the accuracy of the detection result is improved, the efficiency of tunnel deformation detection is improved, and the safety of the tunnel is improved.
