Description

Technical Field

[0001] This invention relates to the field of monitoring equipment, and more particularly to a monitoring device and a photovoltaic analysis platform based on multi-source data monitoring. Background Technology

[0002] Currently, for ground-mounted centralized and industrial / commercial distributed photovoltaic power stations, photovoltaic detection and analysis platforms use monitoring equipment to collect real-time images of photovoltaic arrays, electrical equipment, site environment, and perimeter security around the clock, enabling proactive early warning of shading defects, bird hazards, fire detection, personnel intrusion, and equipment anomalies.

[0003] In existing technologies, surveillance cameras are mostly installed using high-mounted support poles. Equipment installation, as well as subsequent regular inspections and maintenance of the cameras, require working at heights or dismantling the entire support pole. This method is cumbersome. Furthermore, the surveillance cameras and their accessories require cables to connect to the control box, which typically runs through the support pole and connects to the control box on the pole.

[0004] Currently, most support poles have wire holes at the top and bottom, resulting in narrow cable routing paths. This makes cable installation and subsequent maintenance inconvenient. Therefore, there is still room for improvement in how to make the installation of surveillance cameras easier, as well as in cable routing and subsequent maintenance.

[0005] Therefore, it is necessary to provide a new monitoring device to solve the above-mentioned technical problems. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] This invention provides a monitoring device.

[0022] Please refer to the following: Figures 1 to 3 In one embodiment of the present invention, the monitoring device includes: The support rod 1 includes a bottom tube 11 and a top tube 12. The top tube 12 is vertically and elliptically installed at the top of the bottom tube 11. The top tube 12 has a strip-shaped hole 121. Mounting base 2, which is installed on the top end of the top pipe 12, has a horizontally arranged mounting head 21 on the mounting base 2, and a wire hole 211 is opened at the bottom of the mounting head 21; Camera 4 is mounted on the mounting head 21; The sealing structure 5 includes a sealing plate 51 and a slider 52. The slider 52 is laterally slidably installed inside the top tube 12. The sealing plate 51 is used to seal the strip hole 121. The sealing plate 51 is connected to the slider 52 through a connector. A wire-passing opening 122 is reserved between the bottom end of the sealing plate 51 and the lower end of the strip hole 121. Control box 8 is mounted on the bottom tube 11.

[0023] Please refer to the following: Figure 7 (a) and Figure 9 The support rod 1 is installed in the pre-set installation position, the sealing plate 51 is in the pushed-open state, the strip hole 121 is connected to the inside of the top pipe 12, and the top pipe 12 is lowered to a certain height (which can be adjusted to a height that is convenient for the operator to operate according to the height of the operator). Since the support rod 1 is already fixedly installed at this time, the installation position of the support rod 1 will not be offset when the camera 4 is installed, and the installation height is appropriate, which facilitates the quick installation of the camera 4. During installation, the power supply and data transmission cable 20 of camera 4 passes through the wire hole 211 of the mounting head 21 and then enters the top tube 12. The operator's hand (or tools) can enter the inner cavity of the top tube 12 through the upper end of the strip hole 121 to help pull the cable 20 downwards, so that the cable 20 enters the top tube 12 and the entire cable 20 hangs down in the top tube 12. At this time, since the top tube 12 is placed in the bottom tube 11, the cable 20 is not connected to the control box 8. After the cable 20 enters the jacking pipe 12, the camera 4 is fixedly installed with the mounting head 21, and then the jacking pipe 12 is raised to its maximum height.

[0024] Please refer to the following: Figure 7 (a) to Figure 7 (b) During the ascent, the jacking pipe 12 gradually moves out of the bottom pipe 11. The staff can adjust the position of the cable 20 hanging in the jacking pipe 12 through the strip hole 121, and make the bottom end of the cable 20 pass through the bottom of the strip hole 121 and enter the control box 8 through the preset hole of the control box 8 to connect with the internal equipment. After the connection is completed, the staff adjusts the position of the sealing plate 51 so that the sealing plate 51 blocks the strip hole 121. The bottom end of the cable 20 is located in the wire-passing opening 122 formed by the bottom end of the sealing plate 51 and the bottom of the strip hole 121. By blocking the strip hole 121, the cable 20 is protected, which greatly reduces the probability of external environment such as rain and dust corroding the cable 20.

[0025] Similarly, when the camera 4 is subsequently inspected, replaced, or additional equipment is added, the jacking pipe 12 can be lowered, and the cable 20 can be adjusted using the strip hole 121 to achieve quick installation and wiring.

[0026] This invention allows the camera 4 to be lowered to a height that is easy to operate by connecting the top tube 12 and the bottom tube 11 in a height that is adjustable. At this time, the support rod 1 is already fixedly installed, and the installation position of the support rod 1 will not shift when installing the camera 4, thus facilitating the quick installation of the camera 4. At the same time, by opening a strip hole 121 on the top tube 12 and setting a sealing structure 5, the strip hole 121 is opened during installation, which facilitates the adjustment of the cable 20 when threading the wire, and makes it easy for the bottom end of the cable 20 to pass through the threading opening 122, thereby achieving quick threading and further improving the installation speed of the camera 4, making the installation of the camera 4 more convenient.

[0027] The power supply and data transmission cable 20 of the camera 4 can be a single cable 20 that simultaneously provides power and data transmission, or they can be different cables 20.

[0028] In this embodiment, the control box 8 is equipped with devices such as a switch, an air switch, terminal blocks, and a power module. The camera 4 is connected to the switch via a network cable and to the terminal blocks via a power cord. When the network cable and power cord are integrated, the power cord connected to the switch is connected to the terminal blocks.

[0029] Preferably, the length of the strip hole 121 is close to the length of the jacking pipe 12, and the length of the un-hole section at both ends of the jacking pipe 12 is ≤2~5 cm.

[0030] As a preferred embodiment of this example, the sealing block is set to be adapted to the size of the wire threading opening 122, and one or more through holes are opened on the sealing block. The cable 20 passes through the wire threading opening 122 and then through the sealing block. Subsequently, the sealing block is embedded in the wire threading opening 122 to further improve the sealing effect, and a sealing ring is set in the through hole to increase the sealing effect. Please refer to it again. Figure 2 The camera 4 is mounted on the mounting head 21 via a mounting bracket 41. The mounting bracket 41 is equipped with a rotating component. The camera 4 is mounted on the mounting bracket 41 by rotating a shaft. The rotating component is used to control the pitch angle of the camera 4.

[0031] The rotating component can be an automatic control component such as a servo motor, which is fixedly connected to the rotating shaft. Alternatively, it can be a positioning structure such as a knob, which is threaded onto the fixed bracket 41. Tightening the knob abuts against the rotating shaft and limits its movement.

[0032] Please refer to it again. Figure 2 As an optional embodiment, the sealing structure 5 further includes a slide rod 53, which is horizontally installed inside the top pipe 12 and adjacent to the strip hole 121. The slider 52 is sleeved on the slide rod 53 to form a sliding connection.

[0033] Since the slide bar 53 is horizontally installed on the jacking pipe 12, when the sealing plate 51 is opened, it is pushed into the jacking pipe 12, such as... Figure 7 and Figure 8 As shown, the slot 121 can be opened at this time, so that the position of the cable 20 can be adjusted when threading the cable.

[0034] Please refer to the following: Figure 6 , Figure 8 and Figure 10 Preferably, a set of sliding rods 53 is provided at both the upper and lower ends of the strip hole 121, and each set includes two sliding rods 53; the two upper sliding rods 53 are arranged at intervals above the strip hole 121, and the two lower sliding rods 53 are respectively arranged on the left and right sides of the strip hole 121. The two ends of the slider 52 are respectively fitted onto the two slide rods 53, and the two ends of the slider 52 do not completely cover the slide rods 53. Both ends of the slider 52 have arc-shaped slots, and are fitted onto the slide rods 53 by means of the arc-shaped slots.

[0035] Please refer to the following: Figure 7 , Figure 9 and Figure 10 When the cable 20 enters the jacking pipe 12 through the wire hole 211, the staff can adjust the end of the cable 20 to pass through one side of the slide bar 53 to avoid entering between the two slide bars 53.

[0036] Therefore, when the jacking pipe 12 rises and the bottom end of the cable 20 with the strip hole 121 passes through, and the sealing plate 51 is closed, since the two ends of the slider 52 do not fully cover the slide rod 53, and the cable 20 passes through one side of the slide rod 53, the side of the slider 52 and the sealing plate 51 will not push the cable 20 to be outside the jacking pipe 12.

[0037] Preferably, multiple sliding rods 53 can be installed at different height positions on the inner wall of the jacking pipe 12 and on one side of the strip hole 121. After the cable 20 enters the jacking pipe 12 through the wire hole 211, the cable 20 is positioned on one side of the sliding rod 53. The cable 20 is limited by the sliding rods 53 at multiple height positions, which further prevents the cable 20 from moving out of the strip hole 121 and reduces the frequency of manual adjustment.

[0038] In this design, adhesive strips are provided on both sides of the sealing plate 51. After the sealing plate 51 is embedded into the strip hole 121, the adhesive strips are in a compressed state, which improves the sealing performance and the stability of the installation.

[0039] As another optional method in this embodiment, an arc-shaped slide rail is installed on the inner wall of the top pipe 12 and above the strip hole 121. The slider 52 is slidably installed on the arc-shaped slide rail, and the top of the sealing plate 51 is fixedly connected to the slider 52. Thus, the strip hole 121 can be opened by pushing the sealing plate 51 laterally.

[0040] Please refer to the following: Figure 2 and Figure 4 The mounting base 2 is rotatably connected to the top pipe 12. The monitoring equipment also includes an assembly cylinder 3, a rotating device 6, and a limiting rod 7. The assembly cylinder 3 is rotatably mounted on the top of the mounting base 2. An assembly plate 31 is provided inside the mounting base 2. The limiting rod 7 is used to limit the circumferential movement of the assembly cylinder 3. The rotating device 6 includes a motor 61 and a connecting block 62. The motor 61 is mounted on the assembly plate 31. The connecting block 62 is fixedly connected to the output shaft 611 of the motor 61 and the mounting base 2.

[0041] In this embodiment, the limiting rod 7 is used to limit the circumferential movement of the assembly cylinder 3, which means limiting the rotational movement of the assembly cylinder 3.

[0042] That is, the assembly cylinder 3 cannot rotate relative to the mounting base 2, so the motor 61 cannot rotate relative to the mounting base 2, allowing the motor 61 to stably drive the mounting base 2 to rotate.

[0043] Existing monitoring equipment, such as spherical monitoring equipment, has a self-rotation function. However, in use, the monitoring equipment is usually mounted on the support pole 1 by a mounting bracket, which is usually horizontally mounted on the fixed pole. When the monitoring device is placed between two photovoltaic panels 30 and monitors only one side of the photovoltaic panel area, if it needs to rotate 180° to monitor the other side area, the field of view of the camera 4 is easily blocked by the support pole 1, making it difficult to monitor both areas.

[0044] By rotating the assembly cylinder 3 to the top pipe 12, the motor 61 drives the connecting block 62 to rotate the assembly cylinder 3, thereby rotating the camera 4 and adjusting the monitoring direction of the camera 4.

[0045] It is understood that in this embodiment, there is a preset rotation gap between the limiting rod 7 and the bracket rod 1 so as not to obstruct the rotation of accessories such as the camera 4.

[0046] Please see Figure 11 In (a), by rotating the camera 4 to the other side of the support rod 1, it is possible to monitor the photovoltaic panels 30 in different areas, thereby increasing the monitoring range of the camera 4. Furthermore, by rotating the camera 4 directly to the other side of the support rod 1, the monitoring view will not be obstructed.

[0047] It is understandable that when the camera 4 is monitoring the photovoltaic panel 30, the support rod 1 is located on the side of the camera 4 and will not obstruct its monitoring view.

[0048] In this embodiment, the assembly plate 31 has a through hole to facilitate the entry of the power cord of the motor 61 into the top tube 12.

[0049] The assembly cylinder 3 and the mounting base 2 are detachably connected, and the top end of the assembly cylinder 3 is threaded with an end cap, which facilitates the assembly of the motor 61.

[0050] The center of the end cap is provided with a mounting base for the lightning rod 10. The grounding wire of the lightning rod 10 passes through the through hole on the mounting plate 31 and finally grounds through the support rod 1.

[0051] By installing lightning rod 10 to prevent lightning strikes, the entire monitoring equipment was damaged by high voltage after the support pole 1 was damaged.

[0052] Please refer to it again. Figure 1 As an optional solution in this embodiment, the bottom end of the bottom tube 11 is provided with a base 111, the bottom end of the limiting rod 7 is installed on the base 111, and the limiting block 32 is horizontally installed on the assembly cylinder 3. The top end of the limiting rod 7 passes through the limiting block 32 and forms a vertical sliding connection.

[0053] The base 111 at the bottom end of the bottom tube 11 is fixedly installed at the preset installation position in the photovoltaic area. The limiting rod 7 is installed on the base 111, so that the assembly cylinder 3 can be stably limited, that is, the motor 61 can be limited, so that the motor 61 can stably drive the mounting base 2 to rotate through the connecting block 62, that is, stably adjust the monitoring direction of the camera 4 and drive the spotlight 9 to reciprocate to drive away birds.

[0054] Furthermore, by setting a limiting rod 7 connected to the assembly cylinder 3, the support rod 1 is prone to swaying due to the unobstructed open photovoltaic area and large crosswind load. The connection between the limiting rod 7 and the assembly cylinder 3 further limits the support rod 1, improving its stability and thus enhancing the stability of the camera 4.

[0055] As another optional solution in this embodiment, the bottom end of the limiting rod 7 can also be connected to the bottom tube 11 through a support block.

[0056] The lifting and lowering function of the jacking pipe 12 in this invention has the following optional embodiments: In one embodiment, a positioning pin is horizontally threaded to the top of the bottom tube 11, and a nut is fixedly installed on one side of the top of the bottom tube 11. One end of the positioning pin passes through the nut and the side wall of the bottom tube 11 in sequence and is threadedly connected to the nut. A knob is provided at one end of the positioning pin outside the bottom tube 11, and an arc-shaped stop block is provided at the other end. A rubber pad is provided on the contact surface of the arc-shaped stop block, and the arc-shaped stop block fits against the outer wall of the top tube 12.

[0057] When adjusting the height of the jacking pipe 12, the positioning pin is rotated by turning the knob, which causes the arc-shaped stop block to loosen the jacking pipe 12. At this time, the jacking pipe 12 can be lowered or raised. After adjusting to the appropriate position, the positioning pin is tightened so that the arc-shaped stop block abuts against the jacking pipe 12 and limits its movement.

[0058] Please see Figure 6 In another embodiment, the bottom end of the top tube 12 extends into the interior of the bottom tube 11 and is threadedly connected to the bottom tube 11.

[0059] By threading the jacking pipe 12 to the bottom pipe 11, the jacking pipe 12 can be raised or lowered relative to the bottom pipe 11 by rotating the jacking pipe 12. In the subsequent maintenance of equipment such as camera 4, the equipment cable 20 is first disassembled from the control box 8, and the sealing plate 51 is opened before rotating the top tube 12 to lower it, so that the cable 20 will not be pulled and tangled by rotation. Opening the sealing plate 51 can adjust the position of the cable 20 so that the cable 20 is kept outside the bottom tube 11. Among them, a threaded surface can be provided on the inner surface of the bottom pipe 11, and a threaded surface can be provided at the bottom end of the top pipe 12 to realize threaded connection; Alternatively, an external threaded surface can be provided on the surface of the top pipe 12, and an internal threaded surface can be provided at the top of the inner wall of the bottom pipe 11 to achieve a threaded connection.

[0060] In this embodiment, the rotating and lifting function of the jacking pipe 12 has the following optional implementation methods: As an optional method in this embodiment, the rotation of the jacking pipe 12 is achieved by manual rotation by the operator or with the aid of tools; Please see Figure 2 In this optional configuration, motor 61 is used only to drive the mounting base 2 to rotate.

[0061] Please see Figure 5 As another optional embodiment, the blocking structure 5 further includes a driving block 54, which is vertically mounted on the slider 52; The rotating device 6 also includes a mounting bracket 63, which is installed at the bottom end of the output shaft 611 of the motor 61; In the initial state, the opening of the assembly 63 is aligned with the drive block 54.

[0062] Please refer to the following: Figure 5 and Figure 8 The initial state refers to the state when camera 4 is fully installed, at which point camera 4 is facing the detection area; one side and bottom of the mounting kit 63 are open for assembly. Please refer to the following: Figure 7 (a) and Figure 8When installing the camera 4, the top tube 12 descends and retracts into the bottom tube 11, the sealing plate 51 is in the open state, the strip hole 121 faces the control box 8, and the sealing plate 51 is opened to the maximum state. At this time, the drive block 54 is fully inserted into the interior of the mounting set 63, the drive block 54 abuts against the side wall of the mounting set 63, the center line of the drive block 54 is collinear with the center line of the mounting set 63, that is, collinear with the center of the motor 61, and the mounting set 63, the drive block 54, the slider 52 and the slide rod 53 form a rotating force-bearing whole, thereby driving the top tube 12 to rotate. After the camera 4 is assembled, the motor 61 drives the assembly 63 to drive the drive block 54 to rotate. The drive block 54 drives the top tube 12 to rotate through the slider 52 and the slide rod 53, so that the top tube 12 and the bottom tube 11 are threaded together and the top tube 12 rises. When it rises to the preset working height, the motor 61 stops. At this time, the strip hole 121 is still facing the control box 8.

[0063] like Figure 7 As shown in (b); subsequently, the bottom end of the cable 20 of the camera 4 can be threaded into the inside of the control box 8 to connect with the internal equipment. During the lifting process, the bottom end of the cable 20 is not connected to the control box 8, thereby preventing the cable 20 from getting tangled and pulled when the top tube 12 rotates.

[0064] After the connection is completed, pull the sealing plate 51 into the strip hole 121 to block the strip hole 121. Adjust the cable 20 so that it is located in the wire threading opening 122.

[0065] At the same time, the sealing plate 51 drives the slider 52 to move, causing the drive block 54 to separate from the mounting bracket 63; thus, when the motor 61 drives the mounting base 2 to rotate and adjusts the monitoring direction of the camera 4, it will not drive the top pipe 12 to rotate.

[0066] Thus, the motor 61 can be used to drive the rotation of the jacking pipe 12 to achieve lifting and lowering, which facilitates the rotation and lifting of the jacking pipe 12 and avoids manual rotation, as the jacking pipe 12 is relatively heavy and manual rotation is difficult.

[0067] When installing equipment such as camera 4, the rotating device 6 can drive the jacking pipe 12 to rise and fall, which facilitates the installation of camera 4. After the installation is completed, the sealing plate 51 blocks the strip hole 121, and the driving block 54 separates from the mounting device 63. The rotating device 6 is used to adjust the monitoring direction of camera 4.

[0068] The rotating device 6 is equipped with a maintenance module, and the control box 8 is equipped with a maintenance control switch. When the maintenance control switch is pressed, the motor 61 will first drive the camera 4 to the starting state, that is, the accessory 63 will make its opening face the drive block 54 and align with it. Even if the opening of the accessory 63 is not aligned with the drive block 54 due to the subsequent adjustment of the monitoring direction of the camera 4, it can be rotated and adjusted first. During subsequent maintenance, similarly, first open the sealing plate 51 to insert the drive block 54 into the assembly 63, and then first unlock the equipment cable 20 from the control box 8 to prevent it from getting tangled during rotation, so that the cable 20 is kept outside the bottom tube 11 for easy subsequent operation.

[0069] Preferably, a rubber pad is provided on the inner wall of the assembly 63. When the drive block 54 is installed into the assembly 63, the rubber pad is squeezed to improve the stability of the assembly.

[0070] Furthermore, bolts can be threaded through and connected to the top pipe 12, and the sealing plate 51 is rotatably connected to the bolts through the assembly block, thereby using the bolts to further limit the position of the assembly 63.

[0071] In this embodiment, the distance between the limiting rod 7 and the mounting base 2 is greater than the maximum distance between the camera 4 and the mounting base 2, so that when the motor 61 drives the top tube 12 to rotate and lift, the mounting base 2 rotates accordingly, and the limiting rod 7 will not block the camera 4 from rotating accordingly. Preferably, when the jacking pipe 12 is lowered, the pitch angle of the camera 4 can be adjusted by rotating the component to rotate the camera 4 downward by the maximum angle, thereby reducing the maximum distance between the camera 4 and the mounting base 2; thereby reducing the setting distance between the limit rod 7 and the support rod 1.

[0072] Please see Figure 3 As a preferred embodiment, the sealing structure 5 further includes a driving block 55, one end of which is mounted on the sealing plate 51.

[0073] The drive block 55 facilitates pushing or pulling the sealing plate 51 to open or block the strip hole 121.

[0074] Preferably, the drive block 55 has a through hole to facilitate pulling the drive block 55.

[0075] As a preferred embodiment, two positioning posts 81 are installed at intervals on the top of the control box 8, and the other end of the drive block 55 is inserted between the two positioning posts 81.

[0076] When the pulling block 55 drives the sealing plate 51 to block the strip hole 121, the pulling block 55 is inserted between the two positioning posts 81, thereby limiting the rotation of the pulling block 55, which in turn limits the rotation of the jacking pipe 12, preventing the jacking pipe 12 from rotating and shifting during use, causing changes in the height of the camera 4, etc., and improving the stability of use.

[0077] Please see Figure 11 (a) The monitoring equipment can be fixedly installed at a preset installation location in the photovoltaic area.

[0078] Please see Figure 11 (b) Alternatively, a sliding rail structure 40 can be set between adjacent photovoltaic areas, and the monitoring equipment can be installed on the sliding rail structure 40. The monitoring equipment can be moved by the sliding rail structure 40, so that a larger area of ​​photovoltaic equipment can be monitored by one monitoring device.

[0079] The slide rail structure 40 includes a slide rail and a drive trolley. The slide rail is laid on the ground, the rollers of the drive trolley are located in the slide rail groove, and the base 111 of the support rod 1 is installed on the drive trolley.

[0080] Please refer to it again. Figure 1 The monitoring device also includes a mounting plate 22, which is mounted on the mounting base 2 and located above the mounting head 21.

[0081] By setting the mounting plate 22, other devices can be added, such as spotlights 9. The spotlights 9 are used as bird deterrents. When the camera 4 or other devices detect birds, the motor 61 drives the mounting base 2 to rotate back and forth within a preset angle through the connecting block 62, thereby driving the spotlights 9 to rotate back and forth. The colored light emitted by the spotlights 9 follows the back and forth rotation, thereby achieving the effect of repelling birds and preventing bird droppings from falling onto the photovoltaic panel 30.

[0082] The mounting base 2 has a through hole to facilitate the cable 20 of the spotlight 9 to pass through the top pipe 12 and enter the control box 8; the mounting plate 22 has a mounting hole to facilitate assembly with the mounting bracket of the spotlight 9.

[0083] The control box 8 is also equipped with a control module for driving the bird deterrent. When the detection equipment such as the camera 4 detects a bird, it drives the spotlight 9 to rotate back and forth to irradiate and deter the bird.

[0084] The working principle of the monitoring equipment provided by this invention is as follows: Please see Figure 7 (a) When installing equipment such as camera 4, the top pipe 12 is lowered and retracted into the bottom pipe 11 (the lowering height can be adjusted according to the height of the workers), the sealing plate 51 is in the open state, the strip hole 121 is facing the direction of the control box 8, and the sealing plate 51 is opened to the maximum state. At this time, the drive block 54 is fully inserted into the interior of the mounting set 63, the drive block 54 abuts against the side wall of the mounting set 63, and the center line of the drive block 54 is collinear with the center line of the mounting set 63, that is, collinear with the center of the motor 61. At this time, the height of the mounting head 21 is convenient for the staff to install the camera 4. When threading the wire, the cable 20 of the camera 4 is passed through the threading hole 211 and then into the top pipe 12, and then the camera 4 is installed. After the camera 4 is assembled, the motor 61 drives the assembly 63 to drive the drive block 54 to rotate. The drive block 54 drives the top tube 12 to rotate through the slider 52 and the slide rod 53, so that the top tube 12 and the bottom tube 11 are threaded together and the top tube 12 rises. When it rises to the preset working height, the motor 61 stops. At this time, the strip hole 121 is still facing the control box 8.

[0085] Please see Figure 7 (b) Subsequently, the bottom end of the cable 20 of the camera 4 can be passed through the strip hole 121 and inserted into the inside of the control box 8 to connect with the internal equipment. During the lifting process, the bottom end of the cable 20 is not connected to the control box 8, thereby preventing the cable 20 from getting tangled and pulled when the top tube 12 rotates. After the connection is completed, pull the sealing plate 51 into the strip hole 121 to block the strip hole 121. Adjust the cable 20 so that it is located in the wire threading opening 122.

[0086] At the same time, the sealing plate 51 drives the slider 52 to move, causing the drive block 54 to separate from the mounting bracket 63; thus, when the motor 61 drives the mounting base 2 to rotate and adjusts the monitoring direction of the camera 4, it will not drive the top pipe 12 to rotate.

[0087] Thus, the motor 61 can be used to drive the rotating jacking pipe 12 to achieve lifting and lowering, which facilitates the rotation of the jacking pipe 12.

[0088] The present invention also provides a photovoltaic analysis platform based on multi-source data monitoring.

[0089] Please see Figure 12 A photovoltaic analysis platform based on multi-source data monitoring includes: a data acquisition module, an analysis and prediction module, and a cleaning module. The data acquisition module includes a parameter acquisition module and the monitoring equipment. The parameter acquisition module is used to collect the operating parameter data, power data and meteorological data of the photovoltaic panel 30; The monitoring equipment is used to collect image data of the photovoltaic panel 30; The analysis and prediction module is used to analyze the data collected by the data acquisition module, predict the power generation of the photovoltaic panel 30, and output a cleaning plan for the photovoltaic panel 30. The cleaning module is used to perform the dust cleaning operation on the photovoltaic panel 30.

[0090] The specific structure of the monitoring equipment is as described in the above embodiments. Since the photovoltaic analysis platform based on multi-source data monitoring adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0091] The data collected by the data acquisition module is transmitted to the database via the gateway.

[0092] The raw data in the database needs to be preprocessed. The preprocessing steps include raw data cleaning, data transformation, data processing, data standardization, and data modeling.

[0093] Raw data cleaning: removing noise, outliers, and duplicate data to ensure data accuracy and consistency, and to avoid analytical biases and decision-making errors caused by erroneous data.

[0094] Data transformation: Convert heterogeneous raw data into a unified format, complete normalization processing, eliminate differences in the dimensions of different features, and improve the computational performance of the algorithm.

[0095] Data processing: Perform statistical calculations on the cleaned and transformed data to obtain average, maximum, minimum, daily power consumption, monthly power consumption, and daily average power consumption indicators, and perform multi-source data fusion to generate composite business indicators.

[0096] Data standardization: Eliminates inconsistencies in data encoding, format, and terminology, facilitating data sharing and integration within the enterprise.

[0097] Data modeling: Build standardized data models, optimize data read and write efficiency, and support upper-level business decisions.

[0098] The sub-prediction module includes a power generation prediction model.

[0099] The power generation prediction model uses sunlight, photovoltaic panel 30's own attributes, historical power generation, dust thickness, temperature, and irradiance as input features. It employs a Long Short-Term Memory (LSTM) network and a Regression Differential Moving Average (ARIMA) algorithm to predict the power generation of the photovoltaic panel 30 after cleaning. LSTM and ARIMA are good at processing time series and can capture the time-series changes in power generation and the long-term dependencies between multiple variables.

[0100] The sub-prediction module can also be configured with a power generation loss prediction algorithm, which is divided into a short-term loss prediction unit and a long-term loss prediction unit.

[0101] The short-term loss prediction unit is used to calculate power generation loss in the next few days; the input data sources include future weather forecast temperature, historical average temperature-average irradiance datasets for the same period, and pollution level data output by dust sensors.

[0102] Short-term loss prediction execution steps: S101: Using linear regression, support vector regression, or LSTM / GRU time series models, combined with weather forecast temperature and historical samples from the same period, predict the irradiance for a period of time in the future. S102: Calculate the theoretical power generation Pclean under ideal conditions without dust pollution based on predicted irradiance and temperature; S103: Call the pre-trained dust pollution-power generation efficiency loss model and output the power generation efficiency loss ratio ηloss; S104: Short-term power generation loss is calculated according to Ploss=Pclean×ηloss.

[0103] Furthermore, the long-term loss prediction unit is designed for medium- to long-term loss assessment over the next 1-3 months; inputs include historical power generation data for the same period over the past 1-3 years, historical time-series data from dust sensors, and historical meteorological data; the long-term loss prediction execution steps are as follows: S201: Using time series analysis or machine learning models, predict the degree of dust pollution in the next 1-3 months and analyze the seasonal variation pattern of dust pollution. S202: The random forest algorithm is used to fit the nonlinear relationship between power generation, temperature and irradiance, and the baseline power generation Pclean under dust-free conditions is output. S203: Combine the predicted amount of dust accumulation pollution and call the efficiency loss model to obtain the long-term power generation efficiency loss ratio ηloss. S204: Calculate the long-term power generation loss Ploss = Pclean × ηloss.

[0104] The analysis and prediction module also includes a difference analysis model; the difference analysis model includes a power generation statistics unit for ideal clean state, a power generation statistics unit after cleaning, a power generation statistics unit for uncleaned state, a first difference comparison unit, and a second difference comparison unit. The ideal clean state power generation statistics unit calculates the power generation of photovoltaic panel 30 under ideal clean state based on light intensity and light duration.

[0105] The power generation statistics unit after cleaning reads the voltage, current and running time of the photovoltaic panel after cleaning, and calculates the actual power generation after cleaning. The power generation statistics unit for the uncleaned state is used to calculate the power generation by directly collecting the electrical parameters of the control group when the power station has 30 uncleaned control photovoltaic panels; when there is no control group or the data collected from the control group is abnormal, the power generation in the uncleaned state is estimated by relying on historical sunshine, weather and predicted dust thickness.

[0106] The first difference comparison unit uses ideal clean power generation as the dependent variable and environmental factors such as light intensity and temperature as independent variables to construct a linear regression model, compare the current actual power generation with the ideal power generation, quantify the current performance loss of photovoltaic panels 30, and provide a basis for whether to start cleaning operations and assess the potential benefits of cleaning. The second difference comparison unit compares the power generation after cleaning with the power generation in the uncleaned state to obtain the increase in power generation brought about by the cleaning operation, which is used to evaluate the necessity and economic benefits of the cleaning work.

[0107] The analysis and prediction module also includes a cleaning plan analysis and prediction model.

[0108] The cleaning plan analysis and prediction model receives outputs from the difference analysis model and the model prediction module, while also incorporating external variables such as cleaning costs, meteorological data, and market electricity prices. With maximizing power generation revenue as the objective function, constraints include a cleaning cost budget and a power generation target for the power plant. A genetic algorithm is used to find the optimal solution in the multi-factor solution space, outputting the optimal cleaning date and time, as well as the expected power generation and revenue after cleaning. The genetic algorithm simulates the natural selection mechanism, making it suitable for this type of multi-constraint, multi-variable optimization scenario.

[0109] The cleaning module can use a photovoltaic cleaning robot or be configured with manual cleaning tools to complete the dust removal operation of the photovoltaic panels 30.
