Description

Technical Field

[0001] The present invention relates to the field of radar technology, and particularly to a landslide monitoring method, an electronic device, and a storage medium based on radar. Background Art

[0002] With the rapid development of the country's infrastructure, more and more transportation facilities such as roads, railways, and bridges are built on the slopes prone to geological disasters. As a highly destructive geological disaster, landslides constantly threaten the safety of human life and property and the normal operation of various infrastructure facilities. Therefore, efficient and accurate landslide monitoring technology is of great significance for disaster warning and prevention.

[0003] Currently, existing technologies mostly rely on a single millimeter-wave radar to detect a single corner reflector to judge landslides. However, this monitoring method has many drawbacks and seriously lacks multi-dimensional data support. A landslide is a complex three-dimensional spatial movement process. A single millimeter-wave radar can only provide limited one-dimensional or two-dimensional data and is difficult to completely and accurately describe the displacement changes of the mountain body in space. For example, it is impossible to simultaneously obtain the lateral and longitudinal displacements of the mountain body in the horizontal direction and the lifting changes in the vertical direction. The direct consequence of this lack of multi-dimensional data is that potential dangerous changes in other directions of the mountain body cannot be detected, and a comprehensive, accurate, and reliable basis for disaster warning cannot be provided. In the face of complex mountain geological conditions and diverse landslide incentives, misjudgment or missed judgment is extremely likely to occur, thus delaying the best opportunity to respond to disasters and bringing great risks to people's lives, property, and infrastructure.

[0004] In summary, the existing technology for judging landslides based on a single millimeter-wave radar detecting a single corner reflector has significant deficiencies in terms of monitoring comprehensiveness, data integrity, and warning reliability. There is an urgent need for innovative monitoring methods to improve the warning ability for landslide disasters and effectively ensure the safety of people's lives and property and the stable operation of infrastructure. Summary of the Invention

[0005] The problem to be solved by the present invention is to provide a landslide monitoring method, an electronic device, and a storage medium based on radar to overcome the defect that the existing landslide monitoring method is extremely prone to misjudgment or missed judgment due to lack of multi-dimensional data support.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: A landslide monitoring method based on radar includes the following steps:

[0007] Taking the corner reflectors arranged on the monitored mountain body as targets, simultaneously obtaining the displacement information of the corner reflectors through more than three millimeter-wave radars arranged outside the monitored mountain body;

[0008] Taking any one of the millimeter-wave radars as the center point, receiving the displacement information of the corner reflector measured by the remaining millimeter-wave radars, and calculating the displacements Δx, Δy, and Δz of the corner reflector in three dimensions in the Cartesian coordinate system based on the three-dimensional coordinate values of each millimeter-wave radar and the initial three-dimensional coordinate value of the corner reflector, and real-time outputting the three-dimensional coordinate value of the current corner reflector;

[0009] Comparing the three-dimensional coordinate value of the current corner reflector with a set threshold to realize early warning of the monitored mountain body.

[0010] As a further improvement of the present invention, the millimeter-wave radar measures the displacement information of the corner reflector through phase, that is:

[0011]

[0012] where ΔR mn is the displacement value of the m-th corner reflector measured by the n-th millimeter-wave radar, is the initial phase of the millimeter-wave radar, is the current phase of the millimeter-wave radar, and λ is the wavelength of the millimeter-wave radar in vacuum.

[0013] As a further improvement of the present invention, the millimeter-wave radar serving as the center point calculates the small displacements Δx m , Δy m and Δz m in three dimensions of the m-th corner reflector in the Cartesian coordinate system through the following matrix:

[0014]

[0015] Solving the above matrix by Gaussian elimination method to obtain (Δx m , Δy m , Δz m ), and thus calculating the three-dimensional coordinate value (a m +Δx m , b m +Δy m , c m +Δz m ) of the m-th corner reflector after movement;

[0016] where (a m , b m , c m ) is the initial three-dimensional coordinate value of the m-th corner reflector, (x n , y n , z n ) is the three-dimensional coordinate value of the n-th millimeter-wave radar, and R mnIt is the measured distance value of the m-th angular reflection at the initial position of the n-th millimeter-wave radar.

[0017] As a further improvement of the present invention, since the moving distance of the angular reflection is tiny, R can be mn Regarding the relationship of x, y, and z as linear, that is, the moving distance of the angular reflection relative to the millimeter-wave radar is the accumulation of the projections of the moving distances of the angular reflection in three dimensions in the Cartesian coordinate system on the line connecting the millimeter-wave radar and the angular reflection. Therefore, according to the linear approximation method:

[0018]

[0019] Thus, a system of linear equations with three variables can be obtained:

[0020]

[0021] The matrix is obtained by transforming this system of equations.

[0022] As a further improvement of the present invention, the three-dimensional coordinate values of the millimeter-wave radar and the initial three-dimensional coordinate values of the angular reflection are both obtained through measurement and stored in the upper computer. Any one of the millimeter-wave radars can receive the three-dimensional coordinate values of the millimeter-wave radar and the initial three-dimensional coordinate values of the angular reflection transmitted by the upper computer.

[0023] As a further improvement of the present invention, multiple angular reflections are provided and are respectively arranged at different positions of the monitored mountain body. Any one millimeter-wave radar can simultaneously obtain the displacement information of multiple angular reflections within its detection area, and any one angular reflection is simultaneously within the detection areas of at least three millimeter-wave radars.

[0024] As a further improvement of the present invention, the installation positions of more than three millimeter-wave radars are all different, and at least one of the X coordinate values and Y coordinate values of any two millimeter-wave radars is different.

[0025] As a further improvement of the present invention, all the millimeter-wave radars are communicatively connected through a network to transmit information to each other.

[0026] The present invention also provides an electronic device, including a memory, a processor, and a computer program stored on the memory and executable on the processor. When the processor executes the computer program, the above-mentioned landslide monitoring method based on radar is implemented.

[0027] The present invention also provides a storage medium, on which a computer program is stored. When the computer program is executed by a processor, the above-mentioned landslide monitoring method based on radar is implemented.

[0028] The beneficial effects of the present invention are as follows: The present invention provides a radar-based landslide monitoring method, an electronic device, and a storage medium. By arranging more than three millimeter-wave radars outside the monitored mountain body and simultaneously monitoring the corner reflectors on the mountain body, displacement information of the corner reflectors can be obtained from multiple directions and angles. Based on the three-dimensional coordinate values of each millimeter-wave radar and the corner reflectors, the displacements of the corner reflectors in the three dimensions Δx, Δy, and Δz in the Cartesian coordinate system are accurately calculated, realizing all-round and multi-dimensional precise monitoring of the mountain body displacement. This can not only comprehensively capture the complex displacement changes of the mountain body in space, effectively eliminate monitoring blind spots, but also, through the fusion and analysis of multi-dimensional data, more accurately judge the landslide situation of the mountain body, reduce misjudgments and missed judgments caused by one-sided data, provide a more reliable basis for disaster early warning, minimize the losses caused by landslide disasters, and effectively ensure the safety of people's lives and property and the stable operation of various infrastructure facilities. Further, by using multiple corner reflectors distributed at different positions on the mountain body, the present invention can cover a larger area of the mountain body, avoid monitoring blanks, and will not miss any area where landslides may occur. In addition, the present invention is easy to implement. Only several corner reflectors need to be placed on the mountain body, without the need for power supply or networking, and the infrastructure construction is very convenient.

[0036] The following describes the technical solutions provided by the embodiments of the present application in conjunction with the accompanying drawings.

[0037] Refer to Figure 1 and Figure 2 , the present invention provides a radar-based landslide monitoring method, including steps S1 to S3.

[0038] S1. Using at least one corner reflector arranged on the monitored mountain body as the target, simultaneously obtain the displacement information of the corner reflector through more than three millimeter-wave radars arranged outside the monitored mountain body.

[0039] S2. Taking any one of the millimeter-wave radars as the center point, receive the displacement information of the angle reflection measured by the other millimeter-wave radars, and calculate the displacements Δx, Δy, and Δz of the angle reflection in the three dimensions in the Cartesian coordinate system based on the three-dimensional coordinate values of each millimeter-wave radar and the initial three-dimensional coordinate values of the angle reflection, and output the three-dimensional coordinate values of the current angle reflection in real time.

[0040] S3. Compare the three-dimensional coordinate values of the current angle reflection with the set threshold. Once the three-dimensional coordinate values of the current angle reflection exceed the set threshold, immediately give an early warning to the monitored mountain body.

[0041] In the present invention, more than three millimeter-wave radars are arranged outside the monitored mountain body to simultaneously monitor the angle reflections on the mountain body, and the displacement information of the angle reflections can be obtained from multiple directions and multiple angles. Based on the three-dimensional coordinate values of each millimeter-wave radar and the angle reflection, the displacements of the angle reflection in the three dimensions Δx, Δy, and Δz in the Cartesian coordinate system are accurately calculated, realizing the all-round and multi-dimensional accurate monitoring of the mountain body displacement. This can not only comprehensively capture the complex displacement changes of the mountain body in space, effectively eliminate the monitoring blind area, but also, through the fusion and analysis of multi-dimensional data, more accurately judge the landslide situation of the mountain body, reduce the misjudgment and missed judgment caused by the one-sidedness of the data, provide a more reliable basis for disaster early warning, thus realizing the real-time and accurate early warning of the monitored mountain body, minimizing the losses caused by the landslide disaster, and effectively ensuring the safety of people's lives and property and the stable operation of various infrastructure.

[0042] In the present invention, all millimeter-wave radars are communicatively connected through a network to realize the mutual transmission of information.

[0043] In S1, the millimeter-wave radar measures the displacement information of the angle reflection through the phase, that is:

[0044]

[0045] where, ΔR mn is the displacement value of the m-th angle reflection measured by the n-th millimeter-wave radar, is the initial phase of the millimeter-wave radar, is the current phase of the millimeter-wave radar, and λ is the wavelength of the millimeter-wave radar in vacuum.

[0046] In S2, the three-dimensional coordinate values of all millimeter-wave radars and the initial three-dimensional coordinate values of all angle reflections are obtained through measurement and stored in the upper computer, and any one millimeter-wave radar can receive the three-dimensional coordinate values of the millimeter-wave radar and the initial three-dimensional coordinate values of the angle reflection transmitted by the upper computer.

[0047] Define, (a m , b m , c m) is the initial three-dimensional coordinate value of the m-th corner reflector, (x n , y n , z n ) is the three-dimensional coordinate value of the n-th millimeter-wave radar, R mn is the measured distance value of the n-th millimeter-wave radar to the m-th corner reflector at the initial position, R mn ’ is the measured distance value of the n-th millimeter-wave radar to the m-th corner reflector after movement. It can be known that:

[0048]

[0049] Since the actual movement distance of the corner reflector is tiny, the relationship of R mn with respect to x, y, and z can be approximately regarded as linear, that is, the movement distance of the corner reflector relative to the millimeter-wave radar is the accumulation of the movement distances of the corner reflector in three dimensions in the Cartesian coordinate system projected on the line connecting the millimeter-wave radar and the corner reflector. Therefore, according to the linear approximation method:

[0050]

[0051] Thus, a system of linear equations with three variables can be obtained:

[0052]

[0053] Convert this system of equations into matrix form as follows:

[0054]

[0055] Since (a m , b m , c m ), (x n , y n , z n ), R mn and ΔR mn are all known. Therefore, in S3, the millimeter-wave radar as the center point calculates the tiny displacements Δx m , Δy m and Δz m of the m-th corner reflector in three dimensions in the Cartesian coordinate system through the above matrix.

[0056] In this embodiment, specifically, the Gaussian elimination method is used to solve the above matrix, and (Δx m , Δy m , Δz m ) can be obtained, so as to calculate the three-dimensional coordinate value of the m-th corner reflector after movement (a m + Δx m , b m + Δy m , c m + Δzm )。

[0057] As shown Figure 2 in the figure, S represents the mountain slope. Assuming that a millimeter-wave radar is arranged at three positions A(x1, y1, z1), B(x2, y2, z2), and C(x3, y3, z3) respectively, and O(a m , b m , c m ) is the initial position for measuring the corner reflector, the following matrix can be obtained:

[0058]

[0059] Among them, A(x1, y1, z1), B(x2, y2, z2), C(x3, y3, z3), O(a m , b m , c m ), R m1 , R m2 , R m3 , ΔR m1 , ΔR m2 and ΔR m3 are all known. By using the Gaussian elimination method, (Δx m , Δy m , Δz m ) can be calculated, and the three-dimensional coordinate value O'(a m + Δx m , b m + Δy m , c m + Δz m ) of the m-th corner reflector after movement is output.

[0060] Similarly, when there are four millimeter-wave radars arranged, namely A(x1, y1, z1), B(x2, y2, z2), C(x3, y3, z3) and D(x4, y4, z4), the matrix can be obtained:

[0061]

[0062] Similarly, (Δx m , Δy m , Δz m ) can be calculated, and the three-dimensional coordinate value O'(a m + Δx m , b m + Δy m , c m + Δz m ) of the m-th corner reflector after movement is output.

[0063] It should be noted that due to the ΔR measured by the actual millimeter-wave radar mnThere will be errors. Therefore, the calculation error caused by the measurement error can be reduced by increasing the number of millimeter-wave radars.

[0064] Furthermore, the prior art only relies on a single millimeter-wave radar to detect a single corner reflector to judge landslides. Not only does it have the problems of misjudgment or missed judgment as described in the background art, but also a single millimeter-wave radar is limited by its own perspective and can only obtain corner reflector information from a single direction. Due to the complex and changeable mountain terrain, this single-perspective monitoring is extremely prone to a large number of monitoring blind spots, unable to comprehensively perceive the actual displacement of the mountain body, making the analysis and evaluation of landslides inaccurate and unable to fully understand the true situation of landslides, including key information such as the scale, speed, direction, and potential impact range of the landslide.

[0065] In response to this, the present invention arranges multiple corner reflectors at different positions on the mountain body to be monitored. Any millimeter-wave radar can simultaneously obtain the displacement information of multiple corner reflectors within its detection area, and any corner reflector is simultaneously within the detection areas of at least three millimeter-wave radars, so as to be able to output the three-dimensional coordinate values O' of the moved multiple corner reflectors in real time. By arranging multiple corner reflectors at different positions on the mountain body, the present invention can cover a larger area of the mountain body, avoid the occurrence of monitoring blanks, and the corner reflectors at different positions can sense the displacement changes of the mountain body in the local area where they are located. Taken together, they can comprehensively reflect the displacement of the entire mountain body, which is particularly important for the monitoring of large or complex terrain mountains and will not miss any areas where landslides may occur.

[0066] It can be understood that the installation positions of more than three millimeter-wave radars in the present invention are all different, and at least one of the X coordinate values and Y coordinate values of any two millimeter-wave radars is different. The present invention obtains the three-dimensional position information of the corner reflectors on the mountain body by spacing more than three millimeter-wave radars in the horizontal and vertical directions.

[0067] After simulation, a monitoring system of five corner reflectors + three millimeter-wave radars established based on this method can accurately and real-time detect the three-dimensional coordinate information of the five corner reflectors, so as to monitor the landslides in the coverage area. When the installation positions of the millimeter-wave radars are A(0, 0, 0.5m), B(0, 0, 0), and C(0.5m, 0, 0), when the change in the measured distance is less than 5 cm, the calculation error is not greater than 1 mm.

[0068] Through the description of the above embodiments, those skilled in the art can clearly understand that each embodiment needs to be implemented by means of a combination of a hardware platform and software. Therefore, the present invention also provides an electronic device, which includes a memory, a processor, and a computer program stored on the memory and executable on the processor.

Further, the software programs and modules in the above-mentioned memory may also include an operating system, which may include various software components and / or drivers for managing system tasks (such as memory management, storage device control, power management, etc.), and may communicate with various hardware or software components to provide a running environment for other software.

The above-mentioned processor can be a general-purpose processor, including a central processing unit (CPU), a network processor (NP), etc. It can implement or execute the methods disclosed in various embodiments of the present invention.

[0071] In addition, the present invention also provides a storage medium, on which a computer program is stored, and when the computer program is executed by a processor, it implements the radar-based landslide monitoring method as described above.
