DETAILED DESCRIPTION
[0056] The core of the present invention is to provide a tracking photovoltaic slope roof system to improve the light energy utilization rate of the slope roof.
[0057] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation modes.
[0058] like Figure 2 As shown, the present application provides a tracking photovoltaic slope roof system control method, comprising the following steps:
[0059] S1. Obtain the incident angle of light at the current position and time. The current position and time can be obtained through the Internet, or can be obtained according to the astronomical calendar algorithm, or can be manually set when the tracking photovoltaic slope roof system is installed.
[0060] See also Figure 3 In some embodiments of the present application, the above steps may include the following steps:
[0061] S11, implanting an astronomical calendar, wherein the astronomical calendar is a conventional technology in this field.
[0062] S12, confirming the longitude and latitude. The longitude and latitude can be obtained online, or manually set when the tracking photovoltaic slope roof system is installed, specifically by measuring the longitude and latitude of the current location with a longitude and latitude measuring instrument and manually inputting them; or by setting a positioning instrument, which can obtain the longitude and latitude through satellite or online.
[0063] S13, obtaining the calculated light incident angle. After the current time and longitude and latitude are determined, the calculated light incident angle at the current position can be obtained by a conventional algorithm in the art.
[0064] S14, measuring the solar altitude angle and azimuth to obtain the incident angle of the measured light.
[0065] S15, comparing the difference between the calculated light incident angle and the measured light incident angle to see whether it is within the light incident angle threshold, if yes, executing step S16, otherwise, executing step S17.
[0066] S16, obtaining the incident angle of the light at the current position and the current time.
[0067] In some embodiments of the present application, the step further includes the following steps:
[0068] S17, obtaining the generated power. The generated power can be directly measured or calculated. The conventional method of obtaining the generated power by calculation is to obtain the voltage and current of the generated power to calculate the generated power. Of course, this method is only one method of obtaining the generated power. As long as the generated power can be calculated, it belongs to the protection scope of this application.
[0069] S18, determine whether the fluctuation of the generated power is normal, if it is normal, execute step S19; otherwise, the system self-locks.
[0070] S19: The sensor is blocked, and step S2 is executed.
[0071] S2. Determine the optimal angle of the photovoltaic module based on the corresponding relationship between the light incident angle and the irradiation intensity; and obtain the target driving angle of the driving device based on the slope of the sloping roof.
[0072] See also Figure 4 The slope of a pitched roof is the angle between the roof and the horizontal plane.
[0073] For example, when the slope roof is on the sunny side, the slope is α, and the incident angle of light is β. In order to maximize the absorption of light radiation by the photovoltaic module, the solar panels of the photovoltaic module are perpendicular to the incident direction of the light. The optimal angle at which the photovoltaic module installed on the sunny slope roof should be rotated from the roof is:
[0074] γ1=90°-(90°-α)-(90°-β)=α+β-90°
[0075] When the sloped roof is the shaded side, the optimal angle at which the photovoltaic module should rotate from the roof is:
[0076] γ2=180°-(180°-2α+α+β-90°)=90° +α-β
[0077] And according to the final transmission coefficient and the arrangement angle, the target driving angle of the driving device is obtained. For example, when the transmission coefficient is 1, when the driving end of the driving device is arranged coaxially with the rotating shaft of the photovoltaic module, the target driving angle of the driving device is consistent with the optimal angle.
[0078] After the driving motors on the sunny slope and the shady slope adjust the photovoltaic brackets according to the above-mentioned angles, the photovoltaic modules on both sides will be at the optimal inclination angle.
[0079] There are many driving devices that can achieve the above-mentioned drive. For example, the driving device may include a driving motor, and the output shaft of the driving motor is directly connected to the rotating shaft of the photovoltaic component. The transmission connection can be through a threaded connection, a spline connection, or a flat key connection. As long as the structure can achieve the transmission of torque, it is within the protection scope of this application. Or the driving device may include a driving motor and a transmission mechanism, and the output shaft of the driving motor is connected to the input end of the transmission mechanism, and the output end of the transmission mechanism is connected to the rotating shaft of the photovoltaic component. The above-mentioned transmission mechanism is a gear transmission mechanism or a worm gear transmission mechanism. As long as it can achieve the transmission of the torque output by the driving motor to the rotating shaft of the photovoltaic component, it is within the protection scope of this application.
[0080] Furthermore, the above-mentioned drive device has a built-in braking function, and the specific brake with a braking function is arranged on the drive motor or the transmission mechanism. When the required angle is reached, the brake is activated. The preferred drive motor of the present application has a built-in brake, wherein the brake is in a normally closed state, and when the drive motor is running, the brake is opened, and after the drive motor stops running, the brake is closed for braking.
[0081] In order to detect the driving angle of the driving device in real time, an angle sensor for detecting and feeding back the driving angle of the driving device may also be provided. The angle sensor may be used to detect the driving angle of the transmission mechanism and may also be used to detect the driving angle of the driving motor. Preferably, the driving angle of the driving motor detected by the angle sensor in the present application facilitates subsequent adjustment of the driving angle.
[0082] It should be noted that the photovoltaic assembly includes a photovoltaic bracket and a solar panel arranged on the photovoltaic bracket, and the rotation axis is arranged in the middle of the photovoltaic bracket or on one side of the photovoltaic bracket. When it is arranged in the middle of the photovoltaic bracket, the entire photovoltaic assembly rotates around the rotation axis located in the middle; when it is arranged on one side of the photovoltaic bracket, the entire photovoltaic assembly rotates around the rotation axis located on one side. Preferably, the rotation axis is arranged on one side of the photovoltaic bracket, and when a sloping roof is installed, the rotation axis is close to the top of the sloping roof, so that the sloping roof on the sunny side or the sloping roof on the shady side can adjust the optimal angle of the photovoltaic assembly as a whole, and there will be no situation where part of the photovoltaic assembly is at the optimal angle and the remaining part is not at the optimal angle, thereby further improving the utilization rate of the sloping roof.
[0083] S3. The driving device operates according to the target driving angle to make the photovoltaic module at the optimal angle.
[0084] In this step, after the target driving angle is determined, the driving device can be operated according to the internally stored program. In order to improve the accuracy of the operation of the driving device, the present application may also include the following steps:
[0085] Obtaining an actual driving angle of the driving device; wherein the actual driving angle can be obtained based on an angle sensor, and can also be obtained based on the correspondence between the internally recorded running time and the driving angle. As long as the actual driving angle can be obtained, it is within the protection scope of the present application.
[0086] Compare the actual drive angle with the target drive angle. If the difference between the actual drive angle and the target drive angle is within the angle threshold, the drive device stops running; otherwise, the drive device continues to run. Since the angle sensor and the drive motor have a certain operating accuracy, if the difference between the actual drive angle and the target drive angle is within the angle threshold, it means that the photovoltaic module is at the optimal angle. The optimal angle of the photovoltaic module may have a certain deviation in different positions. As long as this deviation meets the general requirements, it can be understood that the optimal angle meets the requirements.
[0087] The control method of the tracking photovoltaic slope roof system of the present invention can make the photovoltaic components at the optimal angle in real time. Photovoltaic components can be arranged on both the shady side and the sunny side of the slope roof, thereby improving the light energy utilization rate of the slope roof.
[0088] In this application, one side of the photovoltaic module is rotatable. Therefore, the entire photovoltaic module needs to be set with a limit angle. When the limit angle is reached, it means that the photovoltaic module has rotated to the limit position. At this time, the photovoltaic module cannot continue to rotate. For safety and feasibility considerations, the control method also includes the following steps:
[0089] The position information of the photovoltaic module is obtained; the position information can be angle information or displacement information. The angle information can be obtained through an angle sensor or based on the corresponding relationship between the stored time and the driving angle; the displacement information can be obtained by setting a displacement measuring instrument or based on the corresponding relationship between the stored time and the displacement.
[0090] If the position information reaches the first limit position, the drive device stops running; otherwise, the drive device continues to run. The first limit position can be understood as the limit position when rotating in the first direction or the second direction. In the figure, when the photovoltaic component is on the sunny side, the first direction is counterclockwise, and when the photovoltaic component is on the shady side, the first direction is clockwise. Of course, the first direction and the second direction mentioned above can be interchangeable in different regions, which will not be repeated here.
[0091] Furthermore, if the position information reaches the second limit position, the drive device stops running; otherwise, the drive device continues to run. The second limit position can be understood as the limit position when rotating in the second direction or the first direction. In the figure, when the photovoltaic component is on the sunny side, the second direction is clockwise, and when the photovoltaic component is on the shady side, the first direction is counterclockwise. Of course, the first direction and the second direction mentioned above in different regions can be interchangeable, which will not be repeated here.
[0092] For safety reasons, the impact of meteorological information on the strength of photovoltaic modules will be fully considered at the beginning of the design of photovoltaic modules. Correspondingly, the drive device usually has a torque threshold. When the impact of meteorological information on the photovoltaic bracket reaches or exceeds the strength threshold of the photovoltaic module, the drive device will drive the photovoltaic module to reset to improve the photovoltaic module's ability to resist the strength generated by meteorological information.
[0093] Specifically, when the photovoltaic power generation is at the optimal angle, the control method further includes the following steps:
[0094] See also Figure 5 In order to optimize the above method, the method can also switch to different modes according to different working conditions. Specifically, the method can also include the following steps:
[0095] S41 obtains motor parameters and meteorological information; wherein, the meteorological information can be obtained through the Internet, or through terminal equipment, or by setting up a meteorological monitoring unit. The meteorological information can be radiation intensity, wind volume, wind direction, rainfall and snowfall. Correspondingly, different detection elements can be set for different meteorological information, such as an irradiation intensity sensor for detecting wind volume, an anemometer for detecting wind volume and wind direction, a rainfall sensor for detecting rainfall, and a snowfall sensor for detecting snowfall. The relevant equipment can directly adopt mature products, wherein the irradiation intensity sensor and rainfall / snowfall sensor are installed in the middle position of the top of the photovoltaic bracket, and the anemometer is installed in the main wind direction position on the top of the photovoltaic bracket.
[0096] Motor parameters may include parameters such as voltage, current, torque, etc., among which voltage, current and torque can be obtained by setting corresponding detection elements.
[0097] S42 classifies working conditions according to motor parameters and meteorological information; when motor parameters exceed the standard and meteorological parameters exceed the standard, the emergency avoidance mode is executed; when motor parameters are normal and meteorological parameters are normal, the normal tracking mode is executed; when motor parameters exceed the standard and meteorological parameters are normal, the automatic avoidance mode is executed.
[0098] When in emergency avoidance mode, it means that the PV module will be damaged if it continues to maintain the optimal angle. For safety reasons, the drive device stops tracking and drives the PV module to a safe state.
[0099] When in normal tracking mode, it means that the PV panels will not be damaged and the drive unit continues to track.
[0100] When in automatic risk avoidance mode, the system self-locks and generates electricity normally, and the drive device stops tracking.
[0101] See also Figure 6 When the system cannot generate electricity after sunset and the photovoltaic components need to be reset, the control method further includes the following steps:
[0102] S51 PV panels return to their original state;
[0103] S52 obtains motor parameters;
[0104] S53 drive angle returns to zero, the motor continues to be powered;
[0105] S54 determines whether the change of the motor parameter exceeds the motor parameter threshold; if so, the process ends; otherwise, the process proceeds to step S55;
[0106] The S55 photovoltaic module continues to return to its original position.
[0107] S56 drive angle is reset to zero.
[0108] The above is the method for zeroing the system. Of course, the system can also be reset manually or through a terminal device.
[0109] Further, in order to expand the control method of this control method, please refer to Figure 7 , the control method further comprises the following steps:
[0110] S61 receives an operation instruction of the terminal device; the above operation instruction may be an instruction to adjust the photovoltaic module to an optimal angle, or an instruction to adjust the photovoltaic module to a safe state, or an instruction to switch the photovoltaic module to a normal tracking mode, or an instruction to switch the photovoltaic module to an emergency avoidance mode, or an instruction to switch the photovoltaic module to an automatic avoidance mode, or an instruction to switch the photovoltaic module to zero, and the like.
[0111] S62 performs corresponding actions according to the operation instructions. Each actuator performs corresponding actions according to the above instructions. When the instruction is to adjust the photovoltaic assembly to the optimal angle, the control system performs the action of adjusting the optimal angle; when the instruction is to adjust the photovoltaic assembly to a safe state, the control system performs the action of adjusting to a safe state; when the instruction is to switch the photovoltaic assembly to a normal tracking mode, the control system performs the action of normal tracking; when the instruction is to switch the photovoltaic assembly to an emergency avoidance mode, the control system performs the action of the emergency avoidance mode; when the instruction is to switch the photovoltaic assembly to an automatic avoidance mode, the control system performs the action of the automatic avoidance mode; when the instruction is to switch the photovoltaic assembly to zero, the control system performs the action of zeroing.
[0112] The user can use the terminal device to interact with the server through the network to receive or send messages, etc. Various client applications can be installed on the terminal device.
[0113] The terminal device can be hardware or software. When the terminal device is hardware, it can be various electronic devices, including but not limited to smart phones, tablet computers, wearable devices, vehicle-mounted devices, augmented reality (AR) / virtual reality (VR) devices, ultra-mobile personal computers (UMPC), netbooks, laptops, desktop computers and other electronic devices. When the terminal device is software, it can be installed in the electronic devices listed above. It can be implemented as multiple software or software modules (for example, to provide distributed services), or it can be implemented as a single software or software module. The embodiments of the present application do not impose any restrictions on the specific type of electronic device.
[0114] The server may be a server that provides various services, such as a backend server that provides support for a terminal device. The backend server may respond to receiving an information acquisition request sent by a terminal device, analyze the request, etc., obtain a processing result (such as information to be pushed), and return the processing result.
[0115] It should be noted that the server can be hardware or software. When the server is hardware, it can be implemented as a distributed server cluster consisting of multiple servers, or it can be implemented as a single server. When the server is software, it can be implemented as multiple software or software modules (for example, used to provide distributed services), or it can be implemented as a single software or software module. No specific limitation is made here.

[0119] It should be noted that the control system 400 obtains the current position and the current time, which can be obtained through the Internet, or according to the astronomical calendar algorithm, or manually set when the tracking photovoltaic slope roof system is installed. Figure 3 In some embodiments of the present application, the control system 400 may obtain the incident angle of the light at the current position and the current time according to the following steps:
[0120] S11, implanting an astronomical calendar, wherein the astronomical calendar is a conventional technology in this field.

The longitude and latitude can be obtained online, or manually set when the tracking photovoltaic slope roof system is installed, specifically by measuring the longitude and latitude of the current location with a longitude and latitude measuring instrument and manually inputting them; or by setting a positioning instrument, which can obtain the longitude and latitude through satellite or online.

[0127] S17, obtaining the generated power. The generated power can be directly measured or calculated. The conventional method of obtaining the generated power by calculation is to obtain the voltage and current of the generated power to calculate the generated power.

[0129] S19, the sensor is blocked.
[0130] See also Figure 4The slope of the pitched roof is the angle between the roof and the horizontal plane. For example, when the pitched roof is on the sunny side, the slope is α, and the incident angle of light is β. In order to maximize the absorption of light radiation by the photovoltaic module 100, the solar panels of the photovoltaic module 100 are perpendicular to the incident direction of light. The optimal angle at which the photovoltaic module 100 set on the sunny pitched roof should be rotated from the roof is:
[0131] γ1=90°-(90°-α)-(90°-β)=α+β-90°
[0132] When the sloped roof is the shaded side, the optimal angle at which the photovoltaic module 100 should rotate from the roof is:
[0133] γ2=180°-(180°-2α+α+β-90°)=90° +α-β
[0134] And according to the final transmission coefficient and the arrangement angle, the target driving angle of the driving device 200 is obtained. For example, when the transmission coefficient is 1, when the driving end of the driving device 200 is coaxially arranged with the rotating shaft 101 of the photovoltaic module 100, the target driving angle of the driving device 200 is consistent with the optimal angle.
[0135] After the driving motors 201 on the sunny slope and the shady slope respectively adjust the photovoltaic brackets 102 according to the above angles, the photovoltaic components 100 on both sides will be at the optimal inclination angle.
[0136] The driving device 200 is arranged on one side or both sides of the photovoltaic module 100. There are many driving devices 200 that can realize the above-mentioned driving. For example, the driving device 200 may include a driving motor 201, and the output shaft of the driving motor 201 is directly connected to the rotating shaft 101 of the photovoltaic module 100 by transmission. The transmission connection can be through a threaded connection, a spline connection, or a flat key connection. As long as the structure that can achieve the transmission of torque is within the protection scope of this application. Or the driving device 200 may include a driving motor 201 and a transmission mechanism 202, the output shaft of the driving motor 201 is connected to the input end of the transmission mechanism 202 by transmission, and the output end of the transmission mechanism 202 is connected to the rotating shaft 101 of the photovoltaic module 100 by transmission. The above-mentioned transmission mechanism 202 is a gear transmission mechanism 202 or a worm gear transmission mechanism 202. As long as the torque output by the driving motor 201 can be transmitted to the rotating shaft 101 of the photovoltaic module 100, it is within the protection scope of this application. For example, when it is a gear transmission mechanism 202, it includes a driving gear 2021 and a driven gear 2022, wherein the output shaft of the drive motor 201 is fixed to the driving gear 2021, the driving gear 2021 is meshed with the driven gear 2022, and drives the driven gear 2022 to rotate, and the driven gear 2022 is fixed on the rotating shaft 101 of the photovoltaic component 100.
[0137] Furthermore, the driving device 200 has a built-in braking function, and a specific brake with a braking function is arranged on the driving motor 201 or the transmission mechanism 202. When the desired angle is reached, the brake is activated. The preferred driving motor 201 of the present application has a built-in brake, wherein the brake is in a normally closed state, and when the driving motor 201 is running, the brake is opened, and after the driving motor 201 stops running, the brake is closed for braking.
[0138] In order to detect the driving angle of the driving device 200 in real time, an angle sensor for detecting and feeding back the driving angle of the driving device 200 may also be provided. The angle sensor may be used to detect the driving angle of the transmission mechanism 202, and may also be used to detect the driving angle of the driving motor 201. Preferably, the driving angle of the driving motor 201 detected by the angle sensor in the present application is convenient for subsequent adjustment of the driving angle.
[0139] The control system 400 controls the driving device 200 to operate according to the target driving angle so that the photovoltaic module 100 is at the optimal angle. When the target driving angle is determined, the driving device 200 can operate according to the internally stored program. In order to improve the accuracy of the operation of the driving device 200, the control system 400 in the present application can also:
[0140] The actual driving angle of the driving device 200 is obtained; wherein, the actual driving angle can be obtained according to the angle sensor, and can also be obtained according to the correspondence between the internally recorded running time and the driving angle. As long as the actual driving angle can be obtained, it is within the protection scope of the present application.
[0141] Compare the actual drive angle with the target drive angle. If the difference between the actual drive angle and the target drive angle is within the angle threshold, the drive device 200 stops running; otherwise, the drive device 200 continues to run. Since the angle sensor and the drive motor 201 have a certain operating accuracy, if the difference between the actual drive angle and the target drive angle is within the angle threshold, it means that the photovoltaic module 100 is at the optimal angle. The optimal angle of the photovoltaic module 100 may have a certain deviation at different positions. As long as this deviation meets the general requirements, it can be understood that the optimal angle meets the requirements.
[0142] The tracking photovoltaic slope roof system of the present invention can make the photovoltaic components at the optimal angle in real time. The photovoltaic components 100 can be arranged on both the shady side and the sunny side of the slope roof, thereby improving the light energy utilization rate of the slope roof.
[0143] The photovoltaic assembly 100 includes a photovoltaic support 102 and a solar panel 103 arranged on the photovoltaic support 102, and the rotation axis 101 is arranged in the middle of the photovoltaic support 102 or on one side of the photovoltaic support 102. When it is arranged in the middle of the photovoltaic support 102, the entire photovoltaic assembly 100 rotates around the rotation axis 101 located in the middle; when it is arranged on one side of the photovoltaic support 102, the entire photovoltaic assembly 100 rotates around the rotation axis 101 located on one side. Preferably, the rotation axis 101 is arranged on one side of the photovoltaic support 102, and when the sloping roof is installed, the rotation axis 101 is close to the top of the sloping roof, so that the sloping roof on the sunny side or the sloping roof on the shady side can adjust the optimal angle of the photovoltaic assembly 100 as a whole, and there will be no situation where part of the photovoltaic assembly 100 is at the optimal angle and the remaining part is not at the optimal angle, thereby further improving the utilization rate of the sloping roof.
[0144] In the present application, one side of the photovoltaic assembly 100 is rotatable, so the entire photovoltaic assembly 100 needs to be set with a limit angle. When the limit angle is reached, it means that the photovoltaic assembly 100 has rotated to the limit position. At this time, the photovoltaic assembly 100 cannot continue to rotate. For safety and feasibility considerations, the control system 400 also includes a first position sensor, which obtains the position information of the photovoltaic assembly 100; the position information can be angle information or displacement information. The angle information can be obtained through an angle sensor, or based on the corresponding relationship between the stored time and the driving angle; the displacement information can be obtained by setting a displacement meter, or based on the corresponding relationship between the stored time and the displacement.
[0145] The control system 400 determines whether the position information has reached the first limit position. If the position information reaches the first limit position, the drive device 200 stops running; otherwise, the drive device 200 continues to run. The first limit position can be understood as the limit position when rotating in the first direction or the second direction. In the figure, when the photovoltaic component 100 is on the sunny side, the first direction is counterclockwise, and when the photovoltaic component 100 is on the shady side, the first direction is clockwise. Of course, the first direction and the second direction mentioned above in different regions can be interchangeable, which will not be repeated here.
[0146] The control system 400 also includes a second position sensor. If the position information reaches the second limit position, the drive device 200 stops running; otherwise, the drive device 200 continues to run. The second limit position can be understood as the limit position when rotating in the second direction or the first direction. In the figure, when the photovoltaic component 100 is on the sunny side, the second direction is clockwise, and when the photovoltaic component 100 is on the shady side, the first direction is counterclockwise. Of course, the first direction and the second direction mentioned above can be interchangeable in different regions, which will not be repeated here.
[0147] For safety reasons, the photovoltaic assembly 100 will fully consider the impact of meteorological information on the strength of the photovoltaic assembly 100 at the beginning of its design. Correspondingly, the driving device 200 usually has a torque threshold. When the impact of meteorological information on the photovoltaic bracket 102 reaches or exceeds the strength threshold of the photovoltaic assembly 100, the driving device 200 will drive the photovoltaic assembly 100 to reset, so as to improve the ability of the photovoltaic assembly 100 to resist the strength generated by the meteorological information.
[0148] Specifically, when the photovoltaic assembly 100 is at the optimal angle, the control system 400 also includes: a meteorological monitoring unit for collecting meteorological information. The meteorological information can be obtained through the Internet, or through a terminal device, or by setting a meteorological monitoring unit.

The relevant equipment can directly adopt mature products, wherein the irradiation intensity sensor and the rainfall / snowfall sensor are installed in the middle position of the top of the photovoltaic bracket 102, and the anemometer is installed in the main wind direction position at the top of the photovoltaic bracket 102.
[0149] The control system 400 obtains motor parameters and meteorological information; wherein, the meteorological information can be obtained through the Internet, or through terminal equipment, or by setting a meteorological monitoring unit. The meteorological information can be radiation intensity, wind volume, wind direction, rainfall and snowfall. Correspondingly, different detection elements can be set for different meteorological information, such as an irradiation intensity sensor for detecting wind volume, an anemometer for detecting wind volume and wind direction, a rainfall sensor for detecting rainfall, and a snowfall sensor for detecting snowfall. The relevant equipment department can directly use mature products, wherein the irradiation intensity sensor and the rainfall / snowfall sensor are installed in the middle position of the top of the photovoltaic bracket 102, and the anemometer is installed in the main wind direction position at the top of the photovoltaic bracket 102. Motor parameters may include parameters such as voltage, current, torque, etc., wherein voltage, current and torque can be obtained by setting corresponding detection elements.
[0150] The control system 400 classifies working conditions according to motor parameters and meteorological information; when motor parameters exceed the standard and meteorological parameters exceed the standard, the emergency avoidance mode is executed; when motor parameters are normal and meteorological parameters are normal, the normal tracking mode is executed; when motor parameters exceed the standard and meteorological parameters are normal, the automatic avoidance mode is executed.
[0151] When the system cannot generate electricity after sunset and the photovoltaic assembly 100 needs to be reset, the control system 400 also includes: obtaining motor parameters; if the motor parameters are within the motor parameter threshold, then determining that the photovoltaic assembly 100 is reset to zero; otherwise, the driving device 200 drives the photovoltaic assembly 100 to continue to return to its original position, and the driving angle is memorized and reset to zero.
[0152] Further, in order to expand the control method of the system, the control system 400 also includes: an interaction unit for receiving an operation instruction of a terminal device; obtaining a target drive angle according to the operation instruction. Among them, a user can use a terminal device to interact with a server through a network to receive or send messages, etc. Various client applications can be installed on the terminal device. Receive an operation instruction of the terminal device; the above-mentioned operation instruction may be an instruction to adjust the photovoltaic component 100 to an optimal angle, or an instruction to adjust the photovoltaic component 100 to a safe state, or an instruction to switch the photovoltaic component 100 to a normal tracking mode, or an instruction to switch the photovoltaic component 100 to an emergency avoidance mode, or an instruction to switch the photovoltaic component 100 to an automatic avoidance mode, or an instruction to switch the photovoltaic component 100 to zero, and so on. The corresponding actions are specifically executed as follows: when the instruction is to adjust the photovoltaic component 100 to the optimal angle, the control system 400 executes the action of adjusting the optimal angle; when the instruction is to adjust the photovoltaic component 100 to a safe state, the control system 400 executes the action of adjusting to the safe state; when the instruction is to switch the photovoltaic component 100 to a normal tracking mode, the control system 400 executes the action of normal tracking; when the instruction is to switch the photovoltaic component 100 to an emergency avoidance mode, the control system 400 executes the action of the emergency avoidance mode; when the instruction is to switch the photovoltaic component 100 to an automatic avoidance mode, the control system 400 executes the action of the automatic avoidance mode; when the instruction is to switch the photovoltaic component 100 to zeroing, the control system 400 executes the action of zeroing.
