Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on one or more embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0031] The present invention is described in detail below in conjunction with specific implementation methods and the accompanying drawings.

[0032] System Example

[0033] According to an embodiment of the present invention, a solar photovoltaic device monitoring and control system is provided. Figure 1 FIG. 1 is a schematic diagram of the structure of a solar photovoltaic device monitoring and control system provided in this embodiment. The solar photovoltaic device monitoring and control system according to the embodiment of the present invention includes:

[0034] The photovoltaic assembly comprises a first extended photovoltaic panel 1, a reference photovoltaic panel 2 and a second extended photovoltaic panel 3 which are laid in sequence along a horizontal direction, and the first extended photovoltaic panel 1, the reference photovoltaic panel 2 and the second extended photovoltaic panel 3 are laid in a spiral shape at a preset angle along the laying direction;

[0035] The angle adjustment module 4 is fixedly connected to the bottom of the photovoltaic module and is used to adjust the angle of the photovoltaic module according to the adjustment instruction sent by the comparison module 6.

[0036] The voltage acquisition module 5 is electrically connected to each photovoltaic panel and is used to detect the power generation voltage of each photovoltaic panel respectively.

[0037] The comparison module 6 is used to receive the power generation voltage values ​​of the first extended photovoltaic panel 1, the reference photovoltaic panel 2 and the second extended photovoltaic panel 3 collected by the voltage collection module 5 at preset time intervals. When the power generation voltage difference between the first extended photovoltaic panel 1 and the second extended photovoltaic panel 3 is greater than the first preset value, the power generation voltage difference between the first extended photovoltaic panel and the second extended photovoltaic panel is compared, and the larger power generation voltage value is compared with the power generation voltage value of the reference photovoltaic panel 2. If the preset adjustment conditions are met, an adjustment instruction is issued to the angle adjustment module 4, wherein, according to the adjustment instruction, the photovoltaic component is controlled to adjust to the side of the extended photovoltaic panel with a larger power generation voltage according to the preset adjustment angle.

[0038] The solar photovoltaic device monitoring and control system provided in this embodiment, the photovoltaic component includes three photovoltaic panels arranged at equal angles in the horizontal direction along the laying direction, so that the power generation voltage of each photovoltaic panel can be determined by the voltage acquisition module 5, and it can be determined that the extended photovoltaic panel with a larger power generation voltage absorbs the most solar energy. Therefore, the comparison module 6 can determine whether the power generation voltage difference of the three photovoltaic panels meets the adjustment condition of the photovoltaic component according to the preset comparison condition. When the condition is met, an adjustment instruction will be sent to the angle adjustment module 4. This not only ensures that the photovoltaic component changes with the illumination direction of the sunlight, but also makes the photovoltaic component adjust to the direction of greater solar radiation to absorb more solar energy, thereby maximizing the utilization of solar energy as much as possible.

[0039] In one embodiment, reference Figure 1 , the first extended photovoltaic panel 1, the reference photovoltaic panel 2 and the second extended photovoltaic panel 3 are arranged axially in increasing or decreasing angles according to the arrangement order, and the angles between two adjacent photovoltaic panels are equal. For example, the initial state of the reference photovoltaic panel 2 is horizontal, and the inclination angle α 基准 is 0°, then the first extended photovoltaic panels 1 on both sides are arranged at an angle α 1 and the layout angle α of the second extended photovoltaic panel 3 2 They are α 基准 -a° and α 基准 ﹢a°, in this embodiment, a is preferably 2-4; compared with photovoltaic components arranged at the same level, photovoltaic panels set at different angles can determine the direction of stronger sunlight through the voltage difference between them, which can be used as a condition for adjusting the angle of the photovoltaic component, and the angle between the photovoltaic panels is not set very large, so that the voltage difference can be used to determine the direction of stronger sunlight, and at the same time, it can ensure that the photovoltaic panels of the photovoltaic component can be arranged at the same level to ensure that each photovoltaic panel faces the sun at a better angle.

[0040] In this embodiment, the voltage collection module 5 can be a photovoltaic panel voltage collection circuit in the prior art, whose input end is electrically connected to the photovoltaic panel terminal and is used to collect the magnitude of the positive voltage of the photovoltaic panel terminal. The photovoltaic panel voltage collection circuit is not described in detail here.

[0041] In this embodiment, the angle adjustment module 4 is fixedly arranged at the bottom of the reference photovoltaic panel 2, and the first extended photovoltaic panel 1, the reference photovoltaic panel 2 and the second extended photovoltaic panel 3 are fixedly arranged. The angle adjustment module 4 of this embodiment can also be implemented using the photovoltaic panel angle adjustment device in the prior art, as long as this embodiment can be implemented so that the photovoltaic assembly can adjust the swing or angle according to the adjustment instructions.

[0042] The following example illustrates the schematic structure of the angle adjustment module 4, but is not limited to the following structure that can achieve the angle adjustment of the photovoltaic module. It is only used to illustrate how the angle adjustment module 4 can achieve the adjustment of the direction of the reference photovoltaic panel 2. Figure 2 , is a schematic diagram of the connection between the angle adjustment module 4 and the reference photovoltaic panel 2 provided in this embodiment.

[0043] The angle adjustment module 4 includes a rotating part 41, a support rod 42 and a telescopic rod 43. The first end of the support rod 42 is connected to the transmission shaft of the rotating part 41, the second end of the support rod 42 is hinged to the reference photovoltaic panel 2, and the two ends of the telescopic rod 43 are respectively hinged to the support rod 42 and the reference photovoltaic panel 2. During the adjustment process, the angle between the photovoltaic module and the horizontal plane can be adjusted by adjusting the telescopic rod 43, and the rotating part 41 can drive the support rod 42 to rotate around its own axis, so that the photovoltaic module rotates, thereby changing the direction of the photovoltaic module.

[0044] In this embodiment, the comparison module 6 compares and analyzes the real-time monitoring information such as the generated voltage of each photovoltaic panel and the angle information of the corresponding photovoltaic module. First, the generated voltage V 1 and the power generation voltage V of the second extended photovoltaic panel 3 2 If the difference in the generated voltage is greater than the first preset value, the maximum value V of the generated voltage of the two extended photovoltaic panels is further compared. max and the reference photovoltaic panel power generation voltage V 基准 ; Among them, the first preset value is 10% to 25%, for example, V 1 is 50v, V 2 When the voltage difference is 30V, the voltage difference is 20V, then 20V / 50V=0.4, which exceeds 10% to 25%. The selection of 10% to 25% is based on the use scenario of the photovoltaic module. For example, if it is used in a plain area, 10% can be selected, and if it is used in a hilly area, 20% can be selected. There is no specific limitation here.

[0045] In this embodiment, the maximum value V max The power generation voltage V of the reference photovoltaic panel 基准 , if the preset adjustment conditions are met, where the adjustment condition is the maximum value V max Higher than the power generation voltage V of the reference photovoltaic panel 基准 1.2 to 1.5 times of the maximum value V, an adjustment instruction is sent to the angle adjustment module 4 to control the telescopic rod 43 to extend / contract so that the photovoltaic module moves toward the maximum value V maxThe corresponding extended photovoltaic panel side is horizontally axially adjusted to a preset angle, wherein the preset angle is 3° to 5°; in this way, the preset time interval is realized by using the monitored photovoltaic component information to perform orderly comparison and realize the adjustment of the photovoltaic component. Only when the preset conditions are met, the angle adjustment module 4 will issue an adjustment instruction, and no signal will be issued in other cases. In this way, the swing amplitude of the photovoltaic component is adjusted by continuously comparing the power generation voltage of the three photovoltaic panels, so that the photovoltaic component is continuously adjusted in the direction of higher solar energy; in addition, the preset threshold value not only improves the comparison efficiency of the control system, but also avoids the mechanical loss caused by the frequent swing of the photovoltaic component. At the same time, such intelligent control reduces the operating burden of the comparison module to process data, and improves the working efficiency of the control system. After that, this process is circulated to ensure that the entire photovoltaic component slowly approaches the extended photovoltaic panel side of the maximum power generation voltage, so as to ensure that the photovoltaic power generation system can fully absorb and utilize solar energy resources. In addition, the swing angle and adjustment times of the photovoltaic component are stored and documented in a timely manner through the storage module, which is conducive to the relevant personnel to retrieve and check the adjustment frequency and operating status of the photovoltaic power generation system, and provide corresponding basis and guarantee for its operation and maintenance and infrastructure maintenance.

[0046] In this embodiment, a data storage module 7 is also provided for analyzing and processing the photovoltaic component information uploaded by the voltage acquisition module 5, and then recording the power generation voltage of each photovoltaic panel and the angle of the photovoltaic component adjusted by the angle adjustment module 4 and storing them in the storage module to form a file. This is not only beneficial for management personnel to analyze the power generation status of the photovoltaic components, but also can ensure accurate comparison of the information provided by the system for real-time monitoring.

[0047] The beneficial effects of the present invention are:

[0048] (1) The monitoring device of the present invention is composed of three photovoltaic panels placed at different angles, so that more comprehensive sunlight information can be obtained. The installation of the three photovoltaic panels only requires that the extended photovoltaic panel is on the left and right sides of the base photovoltaic panel, and there are no requirements for other specific installation positions. The monitoring device can be applied to photovoltaic power generation systems in different environments and locations.

[0049] (2) The present invention monitors the photovoltaic components in real time, records the power generation voltage and angle of the photovoltaic panels of the voltage acquisition module and forms a file, compares the power generation voltage according to the sequence and presets the threshold value, thereby improving the working efficiency of the control system and reducing the mechanical loss caused by the frequent swinging of the photovoltaic component bracket.

[0050] (3) The concept of the entire control system of the present invention is to monitor the intensity and direction of sunlight, make timely adjustments to the entire photovoltaic module, and record the adjustment information in the storage module to form a file, thereby greatly improving the power generation efficiency of the photovoltaic module, and recording the relevant adjustment information and power generation voltage, which is conducive to relevant personnel to retrieve and check the adjustment frequency and operating status of the photovoltaic power generation system, providing corresponding basis and guarantee for its operation and maintenance and infrastructure repair.
