DETAILED DESCRIPTION

[0042] The exemplary embodiments will be described in detail herein with reference to the attached drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments are not meant to represent all implementations consistent with the application.

[0043] In the past, a single iron wire is usually used to be placed into the desert for observation, which leads to a large error in the measurement of desert wind erosion, and further leads to a large difference between the monitoring results and the actual situation for reflecting the influence of desert wind erosion on the stability of the screw pile in the photovoltaic module. Therefore, it is urgent to research a high-precision monitoring system to improve the authenticity, accuracy and effectiveness of the influence of desert wind erosion on the stability of the screw pile.

[0044] To solve the above technical problems, the overall inventive concept of the present application is how to provide a monitoring system applied to the field of wind erosion monitoring for improving monitoring accuracy.

[0045] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in detail in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0046] Embodiment 1:

[0047] Figure 1 A structural schematic diagram of a monitoring system for the influence of wind erosion on the stability of a screw pile is provided for the embodiments of the present application. As Figure 1 shown, the monitoring system for the influence of wind erosion on the stability of the screw pile mainly includes a photovoltaic module 1, an alignment pile 2 vertically extending into the ground, a monitor 3, and a terminal device 4 in communication connection with the monitor 3; wherein the photovoltaic module 1 includes a screw pile 11 extending into the ground, and the alignment pile 2 is provided with a positioning scale.

[0048] The functions of each device are analyzed as follows: the terminal device 4 controls the monitor 3 to start, and the monitor 3 collects wind erosion data of a target object 5 based on the positioning scale of the contact position of the alignment pile 2 with the ground after starting; wherein the target object 5 is the ground between the screw pile 11 and the alignment pile 2; the terminal device 4 is used to receive the wind erosion data and process the wind erosion data to obtain a monitoring result.

[0049] It should be understood that the solar photovoltaic system includes a plurality of photovoltaic modules 1, each of which can have a corresponding alignment pile 2. The corresponding relationship can be one-to-one correspondence, or a plurality of photovoltaic modules 1 can correspond to one alignment pile 2. Therefore, the embodiments of the present application can be customized according to actual conditions, and the specific form of the above corresponding relationship is not limited in the embodiments of the present application.

[0050] The above terminal device 4 includes but is not limited to: computers, tablets, mobile phones and other smart devices. The ground between the screw pile 11 and the alignment pile 2, or the ground under the photovoltaic panel, the surface of the sand dune, etc. As Figure 1 shown, the initial shape of the target object 5 before being changed by wind erosion (i.e. the change of wind erosion degree) is a plane, and gradually becomes a parabola with the change of wind erosion.

[0051] In addition, the photovoltaic module 1, the alignment pile 2, the monitor 3 and the terminal device 4 are main components of the monitoring system for the influence of wind erosion on the stability of the screw pile, and in addition, the monitoring system can further include other components, for example: various devices for fixing the photovoltaic module 1, the alignment pile 2 and the monitor 3.

[0052] Under the influence of the change of the degree of wind erosion, the ground gradually forms wind erosion pits, and the wind erosion pits are three-dimensional wind erosion ground. When the three-dimensional wind erosion ground is projected onto two dimensions, it is Figure 1 a target object 5 in a parabolic shape.

[0053] Since one target object 5 is in a parabolic shape, and there are multiple target objects 5 on the photovoltaic base, each target object 5 is affected by the degree of wind erosion, and therefore the entire photovoltaic base is in a wavy line shape.

[0054] As can be seen from the above description, since the alignment pile 2 is simple in structure and easy to install, the monitor 3 and the terminal device 4 are easy to obtain, and the positioning scale provided on the alignment pile 2 provides a guarantee for the authenticity of the wind erosion data, through the joint action of the alignment pile 2, the monitor 3 and the terminal device 4, the monitoring system for the influence of wind erosion on the stability of the screw pile can provide an economic, convenient and efficient quantitative method for quantifying the influence of wind erosion on the stability of the screw pile, greatly improving the measurement efficiency and accuracy of the wind erosion change rule (i.e. the degree of wind erosion change rule, the ground deposition deformation rule), and providing an accurate basis for studying the influence of the wind erosion change rule on the stability of the screw pile.

[0055] The working process of the monitoring system for the influence of wind erosion on the stability of the screw pile is described as follows: In this embodiment, the scanner is horizontally adjusted, and under the condition of being powered on, the following processes are executed: ① The starting, collecting (or collecting, acquiring) and saving point cloud data of the scanner 3 are controlled through the visual software in the terminal device 4; ② After the terminal device 4 obtains the point cloud data, the point cloud processing software installed thereon is used for segmentation processing, and the data irrelevant thereto is deleted; ③ According to the wind erosion data of the ground under the photovoltaic panel measured at a certain moment, a certain horizontal position of the alignment pile 2 is taken as the initial value of wind erosion, and the characteristics (for example, x and y coordinates) of the ground at different horizontal positions are obtained; ④ Repeat ①-③ to measure the characteristics (for example, x and y coordinates) of the parabolic ground at different time periods; ⑤ Form the wind erosion change rule, and obtain the monitoring result reflecting the influence of the wind erosion change rule on the stability of the screw pile.

[0056] It should be noted that the wind erosion change rule can be fuzzy information represented by different levels, or specific numerical values after quantization; similarly, the monitoring result can be fuzzy information represented by different levels, or specific numerical values after quantization. For example, the fuzzy information means that from the visual point of view, with the change of wind erosion, the stability of the screw pile gradually decreases. The specific numerical value means that the ground subsidence is n value, which represents the degree of wind erosion of the ground every three months, and when the stability of the screw pile is zero, the corresponding subsidence value is m value. With the passage of time, when sn=m, the stability of the screw pile is zero, and then complete tilting damage occurs, wherein n is the number of three months.

[0057] In summary, the monitoring system for the influence of wind erosion on the stability of the screw pile provided by the embodiment has simple structure and is convenient to use, can accurately measure the change of the wind erosion degree of the sand dune surface in real time, and further improves the authenticity, accuracy and effectiveness of the influence of the change of the wind erosion degree on the stability of the screw pile.

[0058] In a possible implementation manner, the monitor 3 is a three-dimensional laser scanner; wherein the three-dimensional laser scanner comprises at least one of the following: an RGB device, an infrared emitter and a 3D depth sensor.

[0059] It should be understood that the monitor 3 is also called a measuring instrument. The type and specific structure of the monitor 3 are not limited in the embodiment, and the monitor 3 only needs to have the function of collecting wind erosion data. The RGB device can detect the intensity of red, green and blue colors in the light when the 3D depth sensor takes a picture, and adjust the white balance of the 3D depth sensor accordingly to ensure that the image color is more accurate and natural. The infrared emitter is used to emit a beam of invisible infrared light to the corresponding receiving window of the receiver. When the moving target 5 passes between the infrared emitter and the receiver, the infrared beam is interrupted, thereby triggering the 3D depth sensor to take a picture.

[0060] In combination with the three-dimensional laser scanner, the embodiment establishes a monitoring system for the influence of wind erosion on the stability of the screw pile. The system collects point cloud data of the movement change of the ground sand dune under the photovoltaic panel at different time periods through the three-dimensional laser scanner, refers to the whole horizontal position of the alignment pile 2, processes the point cloud data with three-dimensional coordinates through the software (for example, point cloud processing software) in the terminal device 4, and then the accurate wind erosion change rule can be obtained.

[0061] In a possible implementation manner, the 3D depth sensor is composed of three lenses of an infrared camera.

[0062] Since the infrared camera is also called a depth camera three-dimensional laser scanner, the monitor 3 is also called a three-dimensional laser scanner.

[0063] It should be understood that the three lenses of the infrared camera are used to collect images of the ground between the screw pile 11 and the alignment pile 2, and since the three lenses are simultaneously photographed, the wind erosion data of the target object 5 at a certain time collected is three-dimensional point cloud data (referred to as point cloud data for short), and the wind erosion data of the target object 5 at different times can constitute time sequence point cloud data.

[0064] In a possible implementation manner, the monitoring system further includes a power supply, which supplies power to the monitor 3 and the terminal device 4.

[0065] In the embodiments of the present application, the monitor 3 and the terminal device 4 can be respectively provided with respective power supplies; or the terminal device 4 can be supplied with power by the power supply, and the terminal device 4 can supply power to the monitor 3 as a power supply. Therefore, the embodiments of the present application can perform self-defined setting of the power supply according to the rated voltage and the rated power of the monitor 3 when supplying power to the monitor 3.

[0066] Embodiment 2:

[0067] Figure 2 Another monitoring system for monitoring the influence of wind erosion on the stability of the screw pile is provided in the embodiments of the present application. As shown in Figure 2 The photovoltaic assembly 1 further includes a photovoltaic panel 12 arranged at the top of the end of the screw pile 11 away from the ground, and a photovoltaic support 13 arranged between the photovoltaic panel 12 and the screw pile 11.

[0068] It should be understood that the photovoltaic support 13 can be referred to as a support for short, and the material of the photovoltaic support 13 includes but is not limited to aluminum alloy, concrete, steel, etc.; the number of the photovoltaic support 13 includes but is not limited to 2, 6, 8, etc.; and the length of the photovoltaic support 13 includes but is not limited to 1.6 m, 2 m, 5 m, 6 m, 6.4 m, 8 m, 9 m, etc. Therefore, the embodiments of the present application do not specifically limit the material, number, and length of the photovoltaic support 13.

[0069] In a possible implementation manner, when the horizontal length of the target object 5 exceeds the scanning range V of the monitor 3, the number of the monitors 3 is multiple.

[0070] In a possible implementation manner, as shown in Figure 2 The screw pile 11 includes a first screw pile 111 and a second screw pile 112 higher than the first screw pile 111.

[0071] The distance between the first screw pile 111 and the second screw pile 112 is less than the length of the photovoltaic panel 12, and the two sides of the photovoltaic panel 12 are arranged on the top of the first screw pile 111 and the top of the second screw pile 112, respectively.

[0072] As shown in Figure 1 and Figure 2As shown, the greater the parabolic target 5 subsides, the greater the impact on the spiral pile stability, that is, the subsidence degree of the target 5 and the spiral pile stability have a decreasing relationship. And affected by long-term accumulation, when the parabola expands from the first spiral pile 111 to the second spiral pile 112, the overall stability of the photovoltaic module 1 will rapidly decrease due to the influence of one more times.

[0073] For example: the length from the ground to the vertex of the underground end of the first spiral pile 111 is 3m, when the wind erosion degree reaches 1.5m, the first blade of the first spiral pile 111 in figure 2 is exposed from the ground, the first spiral pile 111 begins to tilt, and when the wind erosion degree reaches the second blade of the first spiral pile 111, it is completely collapsed. During this period, the wind erosion degree is reflected on the z-axis, assuming that the ground subsidence is n value, indicating the wind erosion degree of the ground every three months, and the corresponding subsidence value of the spiral pile stability is m value. With the passage of time, when sn=m, the spiral pile stability is zero, and complete tilting failure occurs, where n is the number of three months.

[0074] It should be noted that the distance between the monitor 3 and the photovoltaic module 1 is any value within the scanning range V of the monitor 3; the distance between the monitor 3 and the alignment pile 2 is a preset distance.

[0075] In the embodiment of the application, the scanning range V of the monitor 3 has a length range of [0.8m, 10m], and preferably a range of [0.8m, 4m]. The embodiment of the application does not specifically limit the value of the preset distance, for example: the distance between the monitor 3 and the alignment pile 2 is 3.5m.

[0076] In a possible implementation manner, the monitoring system further comprises a leveling platform arranged below the monitor 3.

[0077] In the embodiment of the application, the leveling platform, also known as the level, is used to maintain the levelness of the monitor 3, and the connection manner between the leveling platform and the monitor 3 is not specifically limited in the embodiment of the application.

[0078] In a possible implementation manner, the cross-sectional area of the alignment pile 2 is greater than the cross-sectional area of the spiral pile 11.

[0079] Since the cross-sectional area of the alignment pile 2 is large enough, and the length of the alignment pile 2 buried underground is much greater than the length of the spiral pile 11 buried underground, the alignment pile 2 is not easily affected by wind erosion, and can provide accurate data support for the embodiment.

[0080] Embodiment 3:

[0081] Figure 3 A flowchart of a monitoring method for the influence of wind erosion on the stability of a spiral pile provided by the embodiment of the application. As shown inFigure 3 As shown in the method for monitoring the influence of wind erosion on the stability of a screw pile, the terminal device in the monitoring system for monitoring the influence of wind erosion on the stability of a screw pile provided in Embodiment 1 or Embodiment 2 comprises the following steps:

[0082] S10, control the monitor to start, so that the monitor collects wind erosion data of the target after starting based on the positioning scale of the contact position of the alignment pile and the ground; wherein the target is the ground between the screw pile and the alignment pile.

[0083] S20, receive the wind erosion data and process the wind erosion data to obtain the monitoring result.

[0084] In the embodiments of the present application, the above processing can refer to existing conventional processing, including but not limited to: finite element difference denoising processing, point cloud segmentation processing, etc. The processing process is not limited in the embodiments of the present application.

[0085] The terminal device is installed with processing software (such as point cloud processing software), through which the wind erosion data can be processed by finite element difference denoising and point cloud segmentation, and then the wind erosion change rule of the ground under the photovoltaic panel affected by wind erosion change can be obtained.

[0086] The point cloud segmentation processing is based on the three-dimensional point cloud data collected by the monitor, and the three-dimensional point cloud data unrelated to the ground can be deleted by frame selection in the point cloud processing software.

[0087] In actual application, for example, Figure 4 As shown in the method for monitoring the influence of wind erosion on the stability of a screw pile, the terminal device in the monitoring system for monitoring the influence of wind erosion on the stability of a screw pile provided in Embodiment 1 or Embodiment 2 comprises the following steps:

[0088] Step S1, debug the device. It should be understood that the debugging here refers to debugging the computer configuration, adjusting the software parameters, etc., so that the terminal device can be matched and connected with the monitor.

[0089] Step S2, obtain parameters. In the embodiments, the parameters refer to a set of point cloud data with three-dimensional coordinates obtained from the monitor, and then the characteristic parameters (including the coordinates of the three feature points on both sides of the parabola and the vertex) are obtained from the point cloud data.

[0090] Step S3, establish a parabolic wind erosion mathematical model. The parabolic wind erosion mathematical model established here is an expression in the form of a parabola.

[0091] Step S4, calculate the characteristic parameters. The calculation of the characteristic parameters here refers to: quantifying the wind erosion change rule by calculating the difference of the characteristic parameters at different times.

[0092] Step S5, evaluating the wind erosion amount change in different positions. It should be understood that the wind erosion amount change refers to the wind erosion change described above, and the embodiment of the present application studies this step S5 in two dimensions, and the wind erosion amount change is described by a two-dimensional area.

[0093] By performing the above steps S1-S5, the embodiment of the present application can improve the measurement efficiency and accuracy of the wind erosion change rule, and provide accurate basis for studying the influence of the wind erosion change rule on the stability of the screw pile.

[0094] In a possible implementation manner, the wind erosion data is time-series point cloud data, and the wind erosion data is processed to obtain a monitoring result, including the following steps.

[0095] S201, performing filtering processing on the time-series point cloud data to obtain filtered time-series point cloud data.

[0096] S202, selecting a plurality of target moments.

[0097] S203, for each target moment, selecting point cloud data of the target moment from the filtered time-series point cloud data, and analyzing terrain feature data of the target object at the target moment and an included angle data between the screw pile and the horizontal plane at the target moment from the point cloud data of the target moment.

[0098] In the embodiment of the present application, the model corresponding to the point cloud data of the target moment is a parabola with an opening upward. The terrain feature data is the coordinates of three feature points on both sides of the parabola and the vertex.

[0099] S204, based on the terrain feature data of all target moments, constructing a first mathematical model for reflecting the wind erosion change rule, and based on the included angle data of all target moments, constructing a second mathematical model for reflecting the included angle change rule.

[0100] In combination with step S203 and step S204, the quantization process of the wind erosion change rule is analyzed as follows in the embodiment of the present application:

[0101] Through the monitoring instrument, three-dimensional point cloud data of the ground (which gradually presents a parabolic shape due to the influence of wind erosion change) under the photovoltaic panel at a moment is obtained, which is simplified into a two-dimensional plane of x and z axes for analysis, to obtain three feature point coordinates of both sides (x1, z1), (x2, z2) of the parabola and the vertex (x3, z3), and then a parabola is fitted. Similarly, different parabolas can be obtained at different time points. By comparing the above three feature point coordinates of the parabolas at different time points, the three feature point coordinate change amounts are obtained, which are quantization data of the influence of wind erosion degree on the ground under the photovoltaic panel.

[0102] The first mathematical model can refer to the parabolic wind erosion mathematical model described above. S205, based on the first mathematical model and the second mathematical model, the correlation analysis of the wind erosion change rule and the angle change rule is carried out, and the monitoring result reflecting the influence of wind erosion on the stability of the screw pile is obtained.

[0103] In a possible implementation, when the horizontal length of the target object exceeds the scanning range V of the monitor, the number of monitors is multiple.

[0104] In step S10, after the monitor is started, the wind erosion data of the target object is collected based on the positioning scale of the position where the alignment pile contacts the ground, including the following steps:

[0105] S101, each monitor collects part of the wind erosion data of the target object based on the positioning scale of the position where the alignment pile contacts the ground after starting.

[0106] S102, splice all the part of the wind erosion data of the target object collected by all the monitors to obtain the wind erosion data of the target object.

[0107] In the embodiment of the application, the scanner can scan a certain row of photovoltaic components in the photovoltaic field (i.e., photovoltaic base), from the edge of the photovoltaic component of the previous row to the edge of the photovoltaic component of the next row.

[0108] Because the scanner has the advantages of convenience and economy, and the imaging data (i.e., the wind erosion data) obtained by the scanner is relatively accurate, the embodiment can improve the monitoring accuracy of the monitoring system. However, due to the limitation of the scanning range, the scanner may not be able to simultaneously capture the ground between all the screw piles and the alignment piles. To address this situation, the embodiment of the application can use multiple scanners for point observation, and the point cloud data splicing method can be used to solve the problem.

[0109] For ease of understanding, the splicing process of the point cloud data is analyzed as follows: ① divide the point cloud data in the software to delete redundant point cloud data; ② open two point cloud data (for example, multiple point cloud data are displayed in a window, and the user selects) to be spliced in the software; ③ move the two point cloud data to the approximate position; ④ complete the splicing through the splicing function provided by the software; ⑤ filter out the coincident points through the filtering function, and the splicing of the two sets of point cloud data can be obtained.

[0110] In a possible implementation, the method further includes:

[0111] The terminal device sends a data storage instruction carrying a preset time period length to the monitor, so that the monitor stores the wind erosion data of the target object collected in different time periods respectively according to the preset time period length.

[0112] The embodiment of the present application can realize automatic monitoring of wind erosion data, and facilitate traceability.

[0113] The monitoring method for the influence of wind erosion on the stability of the screw pile provided by the embodiment is realized based on the monitoring system for the influence of wind erosion on the stability of the screw pile, and therefore, the implementation principle and technical effects are similar, which will not be described here.

[0114] It should be noted that the user information and data (including but not limited to data for analysis, stored data, displayed data, etc.) involved in the present application are all information and data authorized by the user or authorized by all parties, and the collection, use and processing of related data need to comply with relevant laws, regulations and standards of countries and regions, and provide corresponding operation entrances for users to choose authorization or refusal.
