In the past, a single iron wire is commonly used for being placed in a desert for observation, so that a larger error exists in a measured value of the desert wind erosion, and further, a monitoring result for reflecting the influence of the desert wind erosion on the stability of the spiral pile in the photovoltaic module is greatly different from an actual situation. Therefore, a high-precision monitoring system is needed to be researched, and the authenticity, accuracy and effectiveness of the influence of desert wind erosion on the stability of the spiral pile are improved.
In order to solve the technical problems, the general inventive concept of the present application is to provide a monitoring system applied to the field of wind erosion monitoring for improving the monitoring accuracy.
The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Example 1:
fig. 1 is a schematic structural diagram of a monitoring system for wind erosion affecting stability of a screw pile according to an embodiment of the present application. As shown in fig. 1, the monitoring system for the influence of wind erosion on the stability of the screw pile mainly comprises: the photovoltaic module 1, the alignment pile 2 vertically extending into the ground, the monitor 3 and the terminal equipment 4 in communication connection with the monitor 3; the photovoltaic module 1 comprises a spiral pile 11 extending into the ground, and a positioning scale is arranged on the alignment pile 2.
The roles of the devices were analyzed as follows: the terminal equipment 4 controls the monitor 3 to start, and after the monitor 3 starts, wind erosion data of the target object 5 are collected based on the positioning scale of the contact position of the alignment pile 2 and the ground; wherein the target 5 is the ground between the screw pile 11 and the alignment pile 2; the terminal device 4 is configured to receive the wind erosion data, and process the wind erosion data to obtain a monitoring result.
It should be understood that the solar photovoltaic system includes a plurality of photovoltaic modules 1, each photovoltaic module 1 may have a corresponding alignment pile 2, and the corresponding relationship may be one-to-one, or may be that a plurality of photovoltaic modules 1 correspond to one alignment pile 2, so that the embodiment of the present application may be configured in a customized manner according to the actual situation, and the specific form of the corresponding relationship is not specifically limited.
The above-mentioned terminal devices 4 include, but are not limited to: intelligent devices such as computers, tablets, mobile phones and the like. The ground between the screw pile 11 and the alignment pile 2 or the ground called the underside of the photovoltaic panel, the surface of a sand hill, etc. As shown in fig. 1, the initial shape of the target 5 is a plane before the wind erosion changes (i.e., the degree of wind erosion changes), and gradually becomes parabolic as the wind erosion changes.
In addition, the photovoltaic module 1, the alignment pile 2, the monitor 3 and the terminal equipment 4 are main components of the monitoring system for the wind erosion affecting the stability of the screw pile, and in addition, the monitoring system may further include other components, such as: for fixing the various devices of the photovoltaic module 1, the alignment post 2 and the monitor 3.
Under the condition that the ground is subjected to the change of the wind erosion degree, a wind erosion pit is gradually formed, the wind erosion pit is a three-dimensional wind erosion ground, and the three-dimensional wind erosion ground is projected to a two-dimensional view, so that the three-dimensional wind erosion ground is the parabolic target object 5 in fig. 1.
Since one object 5 is parabolic and there are a plurality of objects 5 on the photovoltaic base, each object 5 is affected by the degree of wind erosion, the entire photovoltaic base is wave-shaped.
According to the description, since the alignment pile 2 is simple in structure and convenient to install, the monitor 3 and the terminal equipment 4 are easy to acquire, and the positioning scale arranged on the alignment pile 2 provides guarantee for the authenticity of wind erosion data, the monitoring system for influencing the stability of the spiral pile by wind erosion can provide an economic, convenient and efficient quantification mode by the combined action of the alignment pile 2, the monitor 3 and the terminal equipment 4, the influence of wind erosion on the stability of the spiral pile is quantified, the measurement efficiency and precision of wind erosion change rules (namely wind erosion degree change rules and ground deposition deformation rules) are greatly improved, and an accurate basis is provided for researching the influence of the wind erosion change rules on the stability of the spiral pile.
The working process of the monitoring system for the stability of the spiral pile affected by wind erosion is described as follows: the present embodiment performs a horizontal adjustment of the scanner, and under the condition of power-on, performs the following flow: (1) the starting, collecting (or acquiring) and storing point cloud data of the scanner 3 are controlled by the visualization software in the terminal equipment 4; (2) after the terminal equipment 4 obtains the point cloud data, the point cloud processing software installed by the terminal equipment is utilized to carry out segmentation processing, and the data irrelevant to the point cloud processing software is deleted; (3) according to the wind erosion data of the ground on the lower side of the photovoltaic panel measured at a certain moment, a certain horizontal position of the alignment pile 2 is taken as a wind erosion initial value, and the characteristics (such as x and y coordinates) of the ground at different horizontal positions are obtained; (4) repeatedly executing the steps (1) - (3), and measuring the characteristics (such as x and y coordinates) of the parabolic ground in different time periods; (5) and forming a wind erosion change rule, and obtaining a monitoring result for reflecting the influence of the wind erosion change rule on the stability of the spiral pile.
It should be noted that the wind erosion change rule may be fuzzy information represented by different levels, or may be a quantized specific value; similarly, the monitoring result may be fuzzy information represented by different levels, or may be a quantized specific value. For example, the blur information means: visually, the stability of the screw pile gradually decreases as the wind erosion changes. The specific numerical values refer to: the subsidence of the ground is n, which represents the wind erosion degree of the ground every three months, and the corresponding subsidence value is m when the stability of the screw pile is zero. Over time, when sn=m, the screw pile stability is zero, then a complete tilt failure occurs, where n is the number of three months.
In conclusion, the monitoring system for the stability of the spiral pile affected by wind erosion provided by the embodiment has a simple structure, is convenient to use, and can accurately measure the wind erosion degree change of the sand dune surface in real time, so that the authenticity, accuracy and effectiveness of the influence of the wind erosion degree change on the stability of the spiral pile are improved.
In one possible implementation, the monitor 3 is a three-dimensional laser scanner; wherein the three-dimensional laser scanner comprises at least one of: RGB devices, infrared emitters, and 3D depth sensors.
It should be understood that the monitor 3 is alternatively referred to as a gauge. The embodiment of the application does not limit the type and specific structure of the monitor 3, and the monitor has the wind erosion data acquisition function. The RGB device can detect the intensity of the red, green and blue colors in the light when the 3D depth sensor shoots, and accordingly adjusts the white balance of the 3D depth sensor, so that the color of an image is more accurate and natural. The infrared transmitter is used for transmitting a beam of infrared light invisible to human eyes, and the infrared light beam is opposite to a corresponding receiving window on the receiver, and when a moving object 5 passes between the infrared transmitter and the receiver, the infrared light beam is blocked, so that a 3D depth sensor is triggered to take a picture.
As can be seen by combining with a three-dimensional laser scanner, the embodiment establishes a monitoring system for wind erosion to influence the stability of the spiral pile, the system collects point cloud data of movement change of a ground sand dune on the lower side of a photovoltaic panel in different time periods through the three-dimensional laser scanner, references the whole horizontal plane position of the alignment pile 2, and processes the point cloud data with three-dimensional coordinates through software (such as point cloud processing software) in terminal equipment 4, so that an accurate wind erosion change rule can be obtained.
In one possible implementation, the 3D depth sensor is made up of three lenses of an infrared camera.
Since the infrared camera or the depth camera three-dimensional laser scanner, the monitor 3 is called a three-dimensional laser scanner.
It should be understood that, all three lenses of the infrared camera are used to collect images including the ground between the screw pile 11 and the alignment pile 2, and since the three lenses are simultaneously taken, the collected wind erosion data of the target 5 at a certain moment is three-dimensional point cloud data (simply referred to as point cloud data), and the wind erosion data of the target 5 at different moments can form time-series point cloud data.
In a possible implementation, the monitoring system further comprises a power supply, which supplies power to the monitor 3 and the terminal device 4.
In the embodiment of the present application, the power supplies corresponding to the monitor 3 and the terminal device 4 may be respectively set; the power supply may also be used to supply power to the terminal device 4, the terminal device 4 acting as a power supply to supply power to the monitor 3. Therefore, when the monitor 3 is powered, the embodiment of the application can carry out the self-defined setting of the power supply according to the rated voltage and the rated power of the monitor 3.
Example 2:
fig. 2 is a schematic structural diagram of another monitoring system for wind erosion affecting stability of a screw pile according to an embodiment of the present application. As shown in fig. 2, the photovoltaic module 1 further includes: a photovoltaic panel 12 provided on top of the end of the screw pile 11 remote from the ground, and a photovoltaic bracket 13 supported between the photovoltaic panel 12 and the screw pile 11.
It should be understood that the photovoltaic bracket 13 may be simply referred to as a bracket, and the materials of the photovoltaic bracket 13 include, but are not limited to: aluminum alloys, concrete, steel, etc.; the number of photovoltaic brackets 13 includes, but is not limited to: 2, 6, 8, etc.; the length of the photovoltaic brackets 13 includes, but is not limited to: 1.6m, 2m, 5m, 6m, 6.4m, 8m, 9m, etc., and therefore, the material, number and length of the photovoltaic bracket 13 in the embodiment of the application are not particularly limited.
In a possible implementation, the number of monitors 3 is a plurality when the horizontal length of the object 5 exceeds the scanning range V of the monitors 3.
In one possible implementation, as shown in fig. 2, the screw pile 11 includes a first screw pile 111 and a second screw pile 112 that is higher than the first screw pile 111.
The distance between the first screw pile 111 and the second screw pile 112 is smaller than the length of the photovoltaic panel 12, and two sides of the photovoltaic panel 12 are respectively erected at the top of the first screw pile 111 and the top of the second screw pile 112.
As shown in fig. 1 and 2, as the parabolic target 5 gradually sinks, the effect on the stability of the screw pile is greater, that is, the sinking degree of the target 5 has a decreasing relationship with the stability of the screw pile. And is affected by the accumulation for a long time, the overall stability of the photovoltaic module 1 is drastically reduced by being affected by one more when the parabola expands from the first screw pile 111 to the second screw pile 112.
For example: the length of the ground to the apex of the underground end of the first screw pile 111 is 3m, and when the wind erosion reaches 1.5m, the first blade of the first screw pile 111 in fig. 2 is exposed from the ground, the first screw pile 111 begins to incline, and when the wind erosion reaches the second blade of the first screw pile 111, the first screw pile is completely collapsed. During this period, the wind erosion degree is represented on the z-axis, and the ground subsidence is assumed to be n, which represents the wind erosion degree of every three months the ground is subjected to, and the corresponding subsidence value is m when the screw pile stability is zero. Over time, when sn=m, the screw pile stability is zero, then a complete tilt failure occurs, where n is the number of three months.
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 post 2 is a preset distance.
In the embodiment of the present application, the scanning range V of the monitor 3 is [0.8m,10m ] in length, and the preferred range is [0.8m,4m ], but the value of the preset distance is not specifically limited in the embodiment of the present application, for example: the distance between monitor 3 and alignment peg 2 is 3.5m.
In a possible implementation, the monitoring system further comprises a levelling bench provided under the monitor 3.
In the embodiment of the present application, the leveling platform is also referred to as a level gauge, and is used for maintaining the levelness of the monitor 3, and the connection manner between the leveling platform and the monitor 3 is not particularly limited in the embodiment of the present application.
