[0044] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0045] like Figure 1 FIG. 1 is a functional module diagram of an embodiment of a reflected light tracking system of the present invention. In an embodiment of the reflected light tracking system of the present invention, the reflected light tracking system of the present invention comprises:

[0046] A control subsystem, wherein the control subsystem is used to trigger a control instruction;

[0047] A reflected light tracking subsystem is connected to the control subsystem, and is used to receive the control instruction and perform real-time tracking of the maximum reflected light on the ground based on the control instruction.

[0048] The reflected light tracking system includes a control subsystem 1 and a reflected light tracking subsystem 2. The control subsystem 1 is used to trigger a control instruction and drive the reflected light tracking subsystem 2 to move its position through a digital signal or an analog signal, so as to track the maximum reflected light on the ground in real time through the reflected light tracking subsystem 2.

[0049] It should be noted that, in this embodiment, Figure 2 As shown in the schematic diagram of the reflected light tracking system, the control subsystem 1 is composed of a controller, in which a maximum reflected light chasing algorithm is preset to trigger a control instruction based on the maximum reflected light chasing algorithm, and the control instruction is sent to multiple motors 30. After the motor 30 rotates, it drives transmission mechanisms such as gears and tracks to move the position of the light reflecting component 10 in the reflected light tracking subsystem 2, wherein the motor 30 can control multiple moving mechanisms 101 at the same time.

[0050] Furthermore, the reflected light tracking subsystem includes:

[0051] A motor, the motor being used to receive a control instruction triggered by a maximum reflected light chasing algorithm in the control subsystem;

[0052] A light reflecting assembly, the light reflecting assembly is connected to the motor, and the light reflecting assembly is used to be driven by the motor to move to an optimal light reflecting position corresponding to the maximum light reflected from the ground at a preset time, so as to radiate the maximum light reflected from the ground to the back of the photovoltaic assembly at the optimal light reflecting position;

[0053] A linkage mechanism is connected to the light reflecting assembly, and is used to link a plurality of the light reflecting assemblies to move synchronously.

[0054] It should be noted that, in this embodiment, Figure 3 The first schematic diagram of the structure of the reflected light tracking subsystem shown in the figure shows that the reflected light tracking subsystem 2 may include a light reflecting component 10, a linkage mechanism 20, and a motor 30. The light reflecting component 10 is used to radiate the maximum reflected light from the ground to the back of the photovoltaic component 10, so as to increase the power generation of the back of the photovoltaic component and make full use of the sunlight radiation; the linkage mechanism 20 can drive multiple sets of light reflecting components 10 to move synchronously, wherein the linkage mechanism 20 includes a connecting rod 201; and the motor 30 moves the light reflecting component 10 in the reflected light tracking subsystem 2 through a transmission mechanism such as a gear and a crawler according to the received control command.

[0055] Furthermore, the light reflecting component includes: a moving mechanism, a reflective material and a slide rail, the moving mechanism is arranged on the slide rail and can move relative to the slide rail, the reflective material is arranged on the moving mechanism, the moving mechanism is used to drive the reflective material to move on the slide rail, and the reflective material is used to radiate the maximum reflected light from the ground to the back of the photovoltaic component at the optimal reflective position.

[0056] Specifically, for example, Figure 4The second schematic diagram of the structure of the reflected light tracking subsystem shown in the figure shows that in this embodiment, the cable 1011 can be used as the moving mechanism 101, and the motor 30 drives the pulley to rotate, so that the cable 1011 sleeved on the pulley rotates. The cable 1011 is a high-strength flexible rope such as a steel wire rope. If the cost is not considered, it can also be other rigid rods. Considering that the single-row array in the actual power station is generally composed of multiple prefabricated pipe piles 105, in order to save the cost of the cable 1011, one or more groups of cables 1011 can be set for the single-row array. The reflective material 102 is placed on the cable 1011 and installed on the cable 1011 by fasteners such as a pressure block and a bolt. When the cable 1011 moves forward and backward, the reflective material 102 is also driven to move synchronously. All cables 1011 in the same row are connected by a connecting rod 201, so that each group of cables 1011 can be rotated synchronously. The cable 1011 and the connecting rod 201 and other components are all fixed to the nearest pipe pile 105 through the clamp 104.

[0057] Furthermore, in another embodiment, considering the obstruction of the pipe pile 105 , two sets of reflected light tracking systems can be set up, and reflective materials 102 are arranged in front and behind the pipe pile 105 respectively. The moving direction of the reflective material 102 can be independently driven by different motors 30 .

[0058] Furthermore, the length of the slide rail is consistent with the maximum stroke of the motor and the maximum moving step of the reflective material.

[0059] The motor 30 module drives the moving mechanism 101 equipped with the reflective material 102 to move on the slide rail 103. The length of the laid slide rail 103 determines the moving step length of the reflective material 102 that can be driven by the motor 30. The length of the slide rail 103 is also related to information such as solar radiation intensity, altitude angle and azimuth angle, so that the reflective material 102 can move to the position with the strongest reflected light from the ground at different times, thereby improving the power generation efficiency of the back of the photovoltaic module 40 and increasing the power generation of the system.

[0060] In this embodiment, the reflected light tracking system includes a control subsystem 1 and a reflected light tracking subsystem 2. The control subsystem 1 is used to trigger a control instruction, and drive the reflected light tracking subsystem 2 to move its position through a digital signal or an analog signal, so as to track the maximum reflected light on the ground through the reflected light tracking subsystem 2. The reflected light tracking subsystem 2 may include a light reflecting assembly 10, a linkage mechanism 20, and a motor 30. The light reflecting assembly 10 includes a moving mechanism 101, a reflective material 102, and a slide rail 103. The moving mechanism 101 can carry the reflective material 102, so that the moving mechanism 101 moves synchronously with the reflective material 102 when moving on the slide rail 103; the linkage mechanism 20 can drive multiple moving mechanisms 101 to move synchronously, wherein the linkage mechanism 20 includes a connecting rod 201; and the motor 30 moves the moving mechanism 101 in the reflected light tracking subsystem 2 through a transmission mechanism such as a gear and a crawler according to the received control instruction, so that the reflective material 102 also moves synchronously.

[0061] Compared with the prior art in which the reflective material is fixed at a position, in the present invention, the reflective material is fixed on the moving mechanism in the reflected light tracking subsystem, and then the moving mechanism is controlled by the control command triggered by the control subsystem, and the reflective material is also moved synchronously, so that the reflective material can track the maximum reflected light on the ground in real time. Therefore, the present invention can make full use of the reflected light on the ground through the reflected light tracking system, reflect the maximum reflected light on the ground to the back of the double-sided photovoltaic module as much as possible, improve the power generation efficiency of the back of the double-sided module, increase the power generation of the system, and reduce the cost of laying the reflective material of the system, thereby achieving cost reduction and efficiency improvement.

[0062] Further, based on the various embodiments of the above-mentioned reflected light tracking system, various embodiments of the reflected light tracking method of the present invention are proposed. The reflected light tracking method of the present invention is applied to the above-mentioned reflected light tracking system.

[0063] Please refer to Figure 5 , Figure 5 It is a schematic flow chart of the first embodiment of the reflected light tracking method of the present invention.

[0064] In this embodiment, an embodiment of a reflected light tracking method is provided. It should be noted that, although a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different from that shown here.

[0065] Step S10, triggering a control instruction through the control subsystem;

[0066] Step S20: receiving the control instruction through the reflected light tracking subsystem, and tracking the maximum reflected light on the ground in real time based on the control instruction.

[0067] The control command is triggered by the control subsystem 1, and the control command is received by the motor 30 in the reflected light tracking subsystem 2, and the position of the mobile mechanism 101 in the reflected light tracking subsystem 2 is moved through transmission mechanisms such as gears and tracks, wherein the mobile mechanism 101 can carry the reflective material 102, so that when the mobile mechanism 101 moves on the slide rail 103, the reflective material 102 moves synchronously, thereby realizing real-time tracking of the maximum reflected light on the ground by the reflective material 102, so that the maximum reflected light on the ground is radiated to the back of the photovoltaic module 40 through the reflective material 102, thereby greatly improving the power generation efficiency of the back of the photovoltaic module.

[0068] Furthermore, in the above step S10, “triggering a control instruction through the control subsystem” may include:

[0069] Step S101 : triggering a control instruction based on a maximum reflected light chasing algorithm in the control subsystem.

[0070] Through the preset maximum reflected light chasing algorithm, the position of the mobile mechanism 101 can be changed according to the changes in solar radiation intensity, altitude angle, azimuth angle and other information, that is, the reflective material 102 is moved to the position where the ground reflected light is the strongest in time, so that the maximum ground reflected light can be radiated to the back of the photovoltaic module 40 through the reflective material 102.

[0071] It should be noted that, in this embodiment, parameters such as the parameters of the bracket supporting the photovoltaic components and the sunlight radiation parameters are comprehensively considered in the maximum reflected light chasing algorithm.

[0072] Furthermore, the above step S101, “triggering a control instruction based on the maximum reflected light chasing algorithm in the control subsystem”, includes:

[0073] Step S1011, based on the maximum reflected light chasing algorithm in the control subsystem, the distance between two adjacent photovoltaic modules is equally divided to obtain a plurality of reference points;

[0074] Step S1012, determining the viewing angle coefficient and the sunlight radiation intensity at each of the reference points, determining the optimal reflective position according to the viewing angle coefficient and the sunlight radiation intensity, and triggering a control instruction based on the optimal reflective position.

[0075] According to the maximum reflected light chasing algorithm in the control subsystem, the distance between each photovoltaic module can be equally divided to obtain multiple reference points, and the viewing angle coefficient and sunlight radiation intensity at each reference point can be further determined to obtain the best reflective position at different times according to the viewing angle coefficient and sunlight radiation intensity at each reference point, and the control instruction is triggered based on the best reflective position, so that the reflective material will move to the best reflective position corresponding to each time under the control instruction, and radiate the maximum reflected light from the ground at the best reflective position to the back of the photovoltaic module. Therefore, this embodiment improves the power generation efficiency of the back of the photovoltaic reflective module.

[0076] Furthermore, in the above step S1012, "determining the best reflective position according to the viewing angle coefficient and the sunlight radiation intensity" may include:

[0077] Step a, obtaining the product value of the viewing angle coefficient and the solar radiation intensity at each reference point at a preset time, and determining the maximum product value from a plurality of the product values;

[0078] Step b: taking the reference point corresponding to the maximum product value as the best light-reflecting position at the preset moment, wherein the ground reflected light is strongest at the best light-reflecting position.

[0079] First, the distance between two adjacent photovoltaic modules 40 is divided into multiple reference points 1-n by taking the pipe pile 105 as a reference. Figure 6 As shown, the product value of the viewing angle coefficient and the solar radiation intensity at each reference point at the preset time is determined, and the maximum product value is determined from each product value, and finally the reference point corresponding to the maximum product value is used as the optimal position to complete the construction of the chasing maximum reflection method. Then, when the control instruction is triggered by the chasing maximum reflection method in the control subsystem 1, the reflective material 102 is controlled to move to the optimal position corresponding to the preset time based on the control instruction, so as to realize the real-time tracking of the maximum reflected light of the ground by the reflective material 102.

[0080] Furthermore, in the above step S1012, “determining the viewing angle coefficient and the solar radiation intensity at each of the reference points” may include:

[0081] Step c, obtaining the viewing angle coefficient at each reference point according to the physical parameters of the component carrying the photovoltaic component and the distance between two adjacent photovoltaic components, and determining the sunlight radiation intensity at each reference point at the preset time.

[0082] Before obtaining the product value of the viewing angle coefficient and the solar radiation intensity at each reference point at the preset time, it is necessary to predetermine the viewing angle coefficient at each reference point and the solar radiation intensity at each reference point at the preset time.

[0083] Specifically, for example, Figure 7 As shown, the viewing angle coefficient VF at each reference point is solved according to the style, size, inclination angle of the bracket carrying the photovoltaic assembly 40 and the distance between two adjacent photovoltaic assemblies 40. i , where i∈(1,2,3,…,n). In addition, the whole day is divided into m time periods in equal proportion, from morning to night, they are the 1st, 2nd, 3rd,…,mth moments, and the information such as the sunshine radiation intensity, altitude angle, and azimuth angle at time t is solved according to the local longitude and latitude information, where t∈(1,2,3,…,m). Then, the sunshine radiation intensity W at each reference point at time t is solved according to the style, size, inclination angle, distance between two adjacent photovoltaic modules, and sunshine radiation intensity, altitude angle, azimuth angle, and other information of the bracket. t-i To determine the product value VF of the viewing angle coefficient and the solar radiation intensity at each reference point at a preset time i ×W t-i Finally, the product value at each reference point determines the maximum product value max(VF i ×W t-i ), the reference point at this time is the optimal reflective position corresponding to time t.

[0084] Furthermore, in the above step S10, “tracking the maximum reflected light on the ground in real time based on the control instruction” may include:

[0085] Step S101, moving the reflective material to the optimal position based on the control instruction to track the maximum reflected light on the ground in real time.

[0086] When the control instruction is triggered by the maximum reflected light chasing algorithm in the control subsystem 1, the reflective material 102 will be moved and controlled according to the control instruction, so that the luminescent material 102 moves to the optimal reflective position corresponding to each moment, so as to realize real-time tracking of the maximum reflected light on the ground, thereby improving the power generation efficiency on the back of the photovoltaic module.

[0087] In this embodiment, a control instruction is triggered by the maximum reflection chasing method in the control subsystem, and the control instruction is received by the motor in the reflected light tracking subsystem. According to the control instruction, the reflective material carried by the mobile mechanism in the reflected light tracking subsystem is moved by transmission mechanisms such as gears and tracks, so that the reflective material is moved to the optimal reflective position corresponding to each moment, so as to achieve real-time tracking of the maximum reflected light on the ground, wherein the viewing angle coefficient VF at each reference point is solved according to the style, size, inclination angle, distance between two adjacent photovoltaic modules, and sunlight irradiation intensity, altitude angle, azimuth angle and other information of the bracket. i , and the solar radiation intensity W at each reference point at time t t-iTo determine the product value VF of the viewing angle coefficient and the solar radiation intensity at each reference point at a preset time i ×W t-i Finally, the product value at each reference point determines the maximum product value max(VF i ×W t-i ), the reference point at this time is the optimal reflective position corresponding to time t.

[0088] In the present invention, the control instruction is triggered by the maximum reflected light chasing algorithm in the control subsystem, and then the reflective material carried by the mobile mechanism in the tracking subsystem is moved and controlled by the control instruction, so that the reflective material moves to the optimal reflective position corresponding to the preset time, so as to track the maximum reflected light on the ground in real time. Therefore, the present invention can reflect the maximum reflected light on the ground to the back of the double-sided photovoltaic module as much as possible through the movable reflective material, thereby improving the power generation efficiency of the back of the double-sided module, increasing the power generation of the system, and reducing the cost of laying the system reflective material, thereby achieving cost reduction and efficiency improvement.
