Description

Technical Field

[0001] The present invention relates to the field of photovoltaic technology, and in particular to a photovoltaic panel adjustment method and system, a photovoltaic panel system, and a medium. Background Art

[0002] Photovoltaic panels are devices that use the photovoltaic effect to convert solar energy into electrical energy. They are mainly composed of solar cell chips. When sunlight shines on the solar cell chip, the semiconductor material in the solar cell chip converts photon energy into electron energy, thereby generating electric current.

[0003] The power generation efficiency of photovoltaic panels is directly affected by the orientation and tilt of the photovoltaic panels. To achieve optimal power generation efficiency, the photovoltaic panels need to be kept close to the incident angle of sunlight.

[0004] However, in some weather scenarios without sunlight (such as cloudy weather, continuous rainy weather, etc.), it is difficult to detect the specific position of the sun, and thus it is difficult to accurately adjust the angle value of the photovoltaic panel. Summary of the invention

[0005] The present invention aims at providing a photovoltaic panel adjustment method and system, which can accurately and quickly adjust the angle value of the photovoltaic panel.

[0006] In a first aspect, the present invention provides a photovoltaic panel adjustment method, comprising: acquiring a light intensity value collected by an image sensor, wherein the image sensor is arranged parallel to the photovoltaic panel; determining that no sunlight is detected irradiating the photovoltaic panel at a first moment, and based on an angle value acquired within a first time period before the first moment, determining a target angle value corresponding to an angle value adjustment moment after the first moment; at the angle value adjustment moment, adjusting the angle value of the photovoltaic panel to the target angle value.

[0007] The light intensity value collected by the image sensor is obtained. If no sunlight is detected on the photovoltaic panel at the first moment, the target angle value corresponding to the angle value adjustment moment after the first moment is predicted based on the angle value obtained in the first time period before the first moment, and then the angle value of the photovoltaic panel is adjusted at the corresponding angle value adjustment moment. In this way, the angle value of the photovoltaic panel can be adjusted accurately and quickly even in a weather scene without sunlight.

[0008] Optionally, the photovoltaic panel adjustment method also includes: determining that sunlight is still not detected irradiating the photovoltaic panel at a second moment, and obtaining a historical angle value record; the second moment is located after the first moment in time sequence; the historical angle value record includes a mapping relationship between multiple different moments and historical angle values; at the angle value adjustment moment after the second moment, selecting the historical angle value corresponding to the angle value adjustment moment from the historical angle value record as the target angle value corresponding to the angle value adjustment moment.

[0009] If no sunlight is detected after the second moment, the target angle value is determined based on the historical angle value record. In this way, the actual position of the sun can still be determined in complex environments such as cloudy and low light, thereby achieving accurate and rapid adjustment of the angle value of the photovoltaic panel.

[0013] Based on the light intensity values ​​collected by all pixel areas of the image sensor, it can be determined that the first pixel area with the largest light intensity is the pixel area with the strongest sunlight. If the first pixel area is not in the center area, the angle value of the photovoltaic panel is adjusted to adjust the first pixel area to the center area, so as to turn the photovoltaic panel toward the sun. In this way, the angle value of the photovoltaic panel can be adjusted accurately and quickly.

[0026] As described in the background technology, in some weather scenes with no sunlight or low sunlight intensity (such as cloudy weather, continuous rainy weather, etc.), it is difficult to detect the specific position of the sun.

[0027] In the prior art, an astronomical calendar is usually used to obtain the sun angle value at a certain location at different times of the day, and then the orientation and inclination of the photovoltaic panel are adjusted. However, when the astronomical calendar is used to adjust the photovoltaic panel, it is difficult to accurately and quickly adjust the inclination of the photovoltaic panel.

[0028] The light intensity value collected by the image sensor is obtained. If no sunlight is detected on the photovoltaic panel at the first moment, the target angle value corresponding to the angle value adjustment moment after the first moment is predicted based on the angle value obtained in the first time period before the first moment, and then the angle value of the photovoltaic panel is adjusted at the corresponding angle value adjustment moment. In this way, the angle value of the photovoltaic panel can be adjusted accurately and quickly even in a weather scene without sunlight.

[0029] In order to make the above-mentioned objects, features and beneficial effects of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] The embodiment of the present invention provides a photovoltaic panel adjustment method, referring to Figure 1 , the following is a detailed description through specific steps.

[0031] The photovoltaic panel adjustment method provided in the following embodiments of the present invention can be executed by a control unit with data processing capability. The control unit can be a central processing unit (CPU), a microcontroller (MCU), an embedded processor, a field programmable gate array (FPGA), etc.

[0032] Step 101, obtaining the light intensity value collected by the image sensor.

[0033] In a specific implementation, the light intensity value may be collected by an image sensor, and the light intensity value is the light intensity value detected by a pixel point on the image sensor.

[0034] In the embodiment of the present invention, the image sensor may be arranged in parallel with the photovoltaic panel. Specifically, the image sensor is arranged in parallel with the photovoltaic panel, which may mean that the image sensor and the photovoltaic panel have the same inclination angle relative to the horizontal plane.

[0035] In some embodiments, the image sensor can be attached to the outer surface of the photovoltaic panel, for example, the image sensor is attached to the central area of ​​the photovoltaic panel.

[0036] like Figure 2 As shown, a schematic diagram of the positional relationship between an image sensor and a photovoltaic panel in an embodiment of the present invention is given. Figure 2 In the figure, the image sensor 22 is attached to the central area of ​​the photovoltaic panel 21.

[0037] like Figure 3 As shown, a schematic diagram of an application scenario in an embodiment of the present invention is given. Figure 3 In the embodiment, the photovoltaic panel 21 is fixed to the ground by a support 23. The image sensor 22 is arranged in the central area of ​​the photovoltaic panel 21. The photovoltaic panel 21 converts solar energy into electrical energy under the irradiation of sunlight.

[0038] In other embodiments, the image sensor may be disposed above the photovoltaic panel and parallel to the photovoltaic panel. For example, a bracket is disposed in the center of the photovoltaic panel, and the image sensor is disposed on the bracket, parallel to the photovoltaic panel, and not in contact with the photovoltaic panel.

[0039] In some other embodiments, the image sensor may be disposed on one side of the photovoltaic panel, and when the angle value of the photovoltaic panel is adjusted, the angle value of the image sensor also changes accordingly.

[0040] like Figure 4 As shown, a schematic diagram of the positional relationship between another image sensor and a photovoltaic panel in an embodiment of the present invention is given. Figure 4 In the embodiment, the image sensor 22 and the photovoltaic panel 21 are independently arranged. When the angle value of the photovoltaic panel changes, the angle value of the image sensor 22 changes accordingly to ensure that the image sensor 22 is parallel to the photovoltaic panel 21.

[0041] It is understandable that the positional relationship between the image sensor and the photovoltaic panel is not limited to the above example, and it is only necessary to ensure that the image sensor and the photovoltaic panel are arranged in parallel.

[0042] Step 102 , determining that no sunlight is detected irradiating the photovoltaic panel at a first moment, and determining a target angle value corresponding to an angle value adjustment moment after the first moment based on angle values ​​acquired in a first time period before the first moment.

[0043] In actual applications, it is known that during the operation of photovoltaic panels, there may be cloudy, rainy days, showers and other weather conditions. In some time periods, photovoltaic panels may not be able to detect sunlight.

[0044] For example, the control unit can detect that sunlight shines on the photovoltaic panel during a period of time, and that after a period of time, the sunlight is blocked by clouds and no sunlight shines on the photovoltaic panel.

[0045] In a specific implementation, the control unit may periodically detect whether there is sunlight irradiating the photovoltaic panel. Alternatively, the control unit may also detect in real time whether there is sunlight irradiating the photovoltaic panel.

[0046] If the control unit determines that no sunlight is detected irradiating the photovoltaic panel at the first moment, the angle values ​​at each angle value adjustment moment in the first time period before the first moment can be obtained. The control unit can determine the target angle value corresponding to the angle value adjustment moment after the first moment based on the angle values ​​corresponding to each angle value adjustment moment in the first time period.

[0047] In some embodiments, during a first time period before the above-mentioned first moment, the photovoltaic panel is continuously irradiated by sunlight.

[0048] In a specific implementation, the control unit may determine the angle value adjustment time according to a predetermined period. The control unit may adjust the angle value of the photovoltaic panel at the angle value adjustment time.

[0049] For example, if the predetermined period is 10 minutes, steps 101 to 103 are performed every 10 minutes, so that the angle value of the photovoltaic panel is adjusted every 10 minutes. For another example, if the predetermined period is 2 minutes, steps 101 to 103 are performed every 2 minutes, so that the angle value of the photovoltaic panel is adjusted every 2 minutes.

[0050] In a specific implementation, the longer the predetermined period is, the lower the requirement on the data processing capability of the control unit is, and accordingly, the lower the frequency of adjusting the angle value of the photovoltaic panel is, which will affect the power generation efficiency of the photovoltaic panel. Conversely, the shorter the predetermined period is, the higher the requirement on the data processing capability of the control unit is, and the higher the frequency of adjusting the angle value of the photovoltaic panel is, thereby improving the power generation efficiency of the photovoltaic panel.

[0051] In a specific application, the length of the predetermined period may be set based on the requirements for the processing capability of the control unit and the power generation efficiency.

[0052] The first time period before the first moment may include two or more angle value adjustment moments. The control unit adjusts the angle value of the photovoltaic panel at the angle value adjustment moment. That is, within the first time period, the control unit adjusts the angle value of the photovoltaic panel two or more times.

[0053] For example, if the duration of the first time period is 30 minutes and the predetermined period is 10 minutes, the first time period includes angle value adjustment time T1, angle value adjustment time T2, and angle value adjustment time T3. The control unit adjusts the angle value of the photovoltaic panel at angle value adjustment time T1, angle value adjustment time T2, and angle value adjustment time T3, respectively. The angle value corresponding to angle value adjustment time T1 is θ1, the angle value corresponding to angle value adjustment time T2 is θ2, and the angle value corresponding to angle value adjustment time T3 is θ3.

[0054] The control unit can determine the angle value change trend of the photovoltaic panel in the first time period based on the angle values ​​at different angle value adjustment moments in the first time period. Furthermore, after the first time period, when there is no sunlight irradiating the photovoltaic panel, the target angle value corresponding to the corresponding angle value adjustment moment can be determined based on the angle value change trend.

[0055] In some embodiments, linear interpolation can be used to determine the target angle values ​​corresponding to different angle value adjustment moments in the second time period after the first moment. In other embodiments, a related angle value change trend function can be fitted based on the angle value of the photovoltaic panel in the first time period, and then the target angle values ​​corresponding to different angle value adjustment moments in the second time period can be determined based on the angle value change trend function.

[0056] For example, the first moment is 14:59 on January 1, 2024, the predetermined period is 10 minutes, and the first time period is 30 minutes. The control unit adjusts the angle value of the photovoltaic panel at 14:30, 14:40, and 14:50 (i.e., three angle value adjustment moments), and the angle value obtained at 14:30 is θ1, the angle value obtained at 14:40 is θ2, and the angle value obtained at 14:50 is θ3. θ1, θ2, and θ3 are in an arithmetic progression, the difference is δ, and θ1 is the largest and θ3 is the smallest.

[0057] Therefore, it can be determined that in the first time period, the angle value of the photovoltaic panel tends to gradually decrease. In 25 minutes after the first moment (i.e., the second time period after the first moment), the target angle value corresponding to 15:00 is determined to be θ4=θ3-δ, the target angle value corresponding to 15:10 is θ5=θ4-δ, and the target angle value corresponding to 15:20 is θ5-δ.

[0058] It is understandable that other methods may also be used to obtain the angle value change trend of the photovoltaic panel within the first time period based on the angle values ​​corresponding to the angle value adjustment moments within the first time period.

[0059] Step 103: At the angle value adjustment moment, the angle value of the photovoltaic panel is adjusted to the target angle value.

[0060] In an embodiment of the present invention, a bracket adjustment mechanism coupled to the control unit may be provided. The bracket adjustment mechanism may also be coupled to the photovoltaic panel. The control unit may output an adjustment instruction to the bracket adjustment mechanism, and the adjustment instruction may be used to indicate an adjustment angle value. The bracket adjustment mechanism may adjust the angle value of the photovoltaic panel to a target angle value based on the adjustment instruction. Thus, by adjusting the bracket adjustment mechanism, the angle value of the photovoltaic panel is adjusted.

[0061] In some embodiments, the support adjustment mechanism may be disposed on the support portion of the photovoltaic panel. The angle value of the photovoltaic panel can be adjusted by adjusting the angle value of the support adjustment mechanism.

[0062] In other embodiments, the support adjustment mechanism may also be coupled to the photovoltaic panel through other connection methods to adjust the angle value of the photovoltaic panel.

[0063] In an embodiment of the present invention, if it is detected at the second moment that the photovoltaic panel is still not irradiated by sunlight, a historical angle value record can be obtained, and the historical angle value record may include a mapping relationship between a plurality of different angle value adjustment moments and historical angle values. At the angle value adjustment moment after the second moment (hereinafter referred to as the third moment), the historical angle value corresponding to the third moment is selected from the historical angle value record as the target angle value corresponding to the third moment.

[0064] In a specific implementation, the above historical angle value record can be recorded over a period of time, and the historical angle value record can be updated in real time. When the control unit detects that the photovoltaic panel is irradiated by sunlight, it can record the angle value of the photovoltaic panel corresponding to the corresponding angle adjustment moment, thereby forming a historical angle value record.

[0065] As shown in Table 1 below, a table schematically shows a historical angle value record in an embodiment of the present invention.

[0066]

[0067] Table 1

[0068] In Table 1, the recording time is the time when the control unit adjusts the angle value of the photovoltaic panel, the target angle value is the angle value of the photovoltaic panel corresponding to the corresponding recording time, the valid state refers to whether the corresponding recording time is in the valid period, and the last updated timestamp refers to the time when the historical angle value record is updated.

[0069] Specifically, in Table 1, the historical angle records were updated at 14:32 on January 4, 2024 and 14:42 on January 4, 2024, respectively. The target angle recorded at 14:30 on January 1, 2024 was 45°, and the target angle recorded at 14:40 on January 1, 2024 was 44.5°.

[0070] In a specific implementation, the above historical angle value record has time validity. If the time validity of a certain data in the historical angle value record exceeds the validity period, the data is deleted from the historical angle value record.

[0071] For example, if the validity period is 72 hours, as shown in Table 1, the data recorded at 14:30 on January 1, 2024 exceeds the validity period, so the data is deleted from the historical angle value record. The data recorded at 14:40 on January 1, 2024 has not exceeded the validity period, so the data can continue to be saved in the historical angle value record.

[0072] In the embodiment of the present invention, the historical record corresponding to the third moment can be directly obtained from the historical angle value record by means of table lookup as the target angle value corresponding to the third moment.

[0073] For example, the third moment is 14:50 on January 4, 2024. From the historical angle value records, the target angle value corresponding to 14:50 on January 3 is selected as the target angle value corresponding to the third moment.

[0074] Since the validity period of the historical angle value record may include two days or more, several historical angle values ​​corresponding to the third moment can be selected from the historical angle value record, and their average can be used as the target angle value; or, based on the changing trend of several historical angle values ​​corresponding to the third moment, the target angle value corresponding to the third moment can be determined.

[0075] For example, the third moment is 14:50 on January 4, 2024. From the historical angle value records, the target angle value θ11 corresponding to 14:50 on January 3 and the target angle value θ12 corresponding to 14:50 on January 2 are selected, and the average of θ11 and θ12 is used as the target angle value corresponding to the third moment.

[0076] For another example, based on the difference between θ11 and θ12, the target angle value corresponding to the third moment is determined to be: θ12-(θ11-θ12).

[0077] In an embodiment of the present invention, the specific durations of the first time period and the second time period can be set according to specific application scenarios. For example, the duration of the first time period is set to 30 minutes, and the duration of the second time period is set to 30 minutes. For another example, the duration of the first time period is set to 20 minutes, and the duration of the second time period is set to 40 minutes.

[0078] In an embodiment of the present invention, if sunlight is detected to be irradiating the photovoltaic panel at any time point between the first moment and the third moment, the control unit can obtain the light intensity value collected by each pixel area and adjust the angle value of the photovoltaic panel.

[0079] In a specific implementation, when the control unit detects that sunlight is irradiating the photovoltaic panel, it means that the obstruction (such as clouds) is no longer blocking the sun, so the control unit can continue to adjust the angle value of the photovoltaic panel based on a predetermined period.

[0080] In a specific implementation, the image sensor may be divided into N pixel regions according to a grid structure, each pixel region includes at least one pixel point; N is a positive integer and N≥2.

[0081] For the i-th pixel region among the N pixel regions, the grayscale values ​​of all the pixels in the i-th pixel region can be obtained, the grayscale values ​​of all the pixels in the i-th pixel region are accumulated and summed, and the sum is used as the light intensity value of the i-th pixel region; i is a positive integer and 1≤i≤N. In this way, the light intensity values ​​corresponding to each of the N pixel regions can be obtained.

[0082] It is understandable that other methods may be used to obtain the light intensity values ​​corresponding to each of the N pixel regions. For example, the grayscale average value of each pixel in each pixel region is obtained as the light intensity value corresponding to the corresponding pixel region.

[0083] In the embodiment of the present invention, after obtaining the light intensity value of each pixel area, the pixel area with the maximum light intensity value (hereinafter referred to as the first pixel area) can be determined. If it is detected that the first pixel area is located in the center area, there is no need to adjust the angle value of the photovoltaic panel; if it is detected that the first pixel area is not in the center area, the angle value of the photovoltaic panel needs to be adjusted.

[0084] In a specific implementation, the angle value of the photovoltaic panel is adjusted by adjusting the angle value of the photovoltaic panel to a target angle value so as to adjust the first pixel area to the central area. The central area mentioned above may refer to a portion of the pixel area at the middle position of the image sensor. Specifically, the central area may include M pixel areas, where M is a positive integer.

[0085] like Figure 5 As shown, a schematic diagram of pixel area division of an image sensor in an embodiment of the present invention is given.

[0086] Figure 5 In the example, the image sensor is equally divided into 16 pixel regions according to a grid structure, and the number of pixels in each pixel region is equal. Among them, region 52 is a central region, including 3 pixel regions.

[0087] When the photovoltaic panel is irradiated by sunlight, the control unit can adjust the angle value of the photovoltaic panel at each angle adjustment moment according to a predetermined period, and record the corresponding angle adjustment moment and the angle value corresponding to the angle adjustment moment in the historical angle record.

[0088] In a specific implementation, the control unit may perform Hough circle detection on the image captured by the image sensor. If a circle is detected in the image captured by the image sensor, it is determined that the sun is not blocked, that is, sunlight is irradiated to the photovoltaic panel. Conversely, if no circle is detected in the image captured by the image sensor, it is determined that the sun is blocked, that is, no sunlight is irradiated on the photovoltaic panel.

[0089] In a specific implementation, the control unit may also obtain the average brightness of several brightest pixels in the image captured by the image sensor. If it is detected that the average brightness of several pixels is less than a set value (such as set to 230), it can be determined that the sun is blocked.

[0090] It is understandable that there may be other ways to detect whether the sun is blocked, and the embodiment of the present invention may use existing solutions to detect whether the sun is blocked.
