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

[0053] Example 1

[0054] The embodiment of the present invention provides an intelligent tracking and damping system for a photovoltaic bracket, such as Figure 1 As shown, including:

[0055] Light collection module: A preset sensor group is installed on the photovoltaic bracket to collect real-time light information;

[0056] Light chasing adjustment module: determines the bracket angle coefficient based on real-time light information, converts the bracket angle coefficient into specific control motion parameters, and the control device adjusts the position of the photovoltaic panel according to the received control motion parameters, and determines whether the light chasing is completed through the preset light chasing algorithm;

[0057] Vibration collection module: deploys preset sensors at key nodes of the bracket to collect vibration data of the bracket in real time;

[0058] Shock reduction implementation module: Analyzes real-time vibration data and reduces the vibration of the bracket based on the analysis results and preset methods.

[0059] In this embodiment, the bracket angle coefficient is a parameter used to indicate the inclination angle of the photovoltaic bracket relative to the horizontal plane or the position of the sun. For example, the bracket angle coefficient is 30 degrees, which means that the angle between the bracket and the horizontal plane is 30 degrees. At this time, the photovoltaic panel will receive sunlight at the best angle.

[0060] In this embodiment, the specific control motion parameter refers to the actual adjustment amplitude and direction calculated based on the illumination collection result. For example, if the illumination information shows that the sunlight intensity is biased towards the south, the control motion parameter may be "rotate 15 degrees south";

[0061] In this embodiment, the control device is a mechanical or electronic system for receiving control motion parameters and performing corresponding adjustments, for example, a servo motor is used as the control device to adjust the orientation of the photovoltaic panel according to the received parameters;

[0062] In this embodiment, the preset light-chasing algorithm is a program or formula for calculating the optimal photovoltaic panel angle based on real-time lighting data.

[0063] In this embodiment, the preset sensor deployment refers to selecting and installing the sensor position in the design stage in order to effectively monitor specific parameters. For example, the acceleration sensor is preset and deployed at the bottom and connection point of the bracket to accurately measure the vibration data. The preset sensor, for example, an accelerometer is selected as the preset vibration sensor. The sensor can record the vibration data of the bracket under the action of wind or other external factors in real time, and send this data to the control system for analysis and processing, including acceleration sensors, vibration sensors or strain gauges. The specific selection depends on the monitoring requirements and bracket design;

[0064] In this embodiment, the key node refers to the position in the support structure that has a greater impact on the overall performance. For example, the connection parts and support points of the support are key nodes because these places are easily affected by greater vibration;

[0065] In this embodiment, the vibration data of the bracket refers to the information about the movement and vibration of the bracket collected by the sensor, for example, the vibration frequency and amplitude data recorded by the vibration sensor, such as "the vibration frequency is 10 Hz, and the vibration amplitude is 5 mm".

[0066] In this embodiment, the preset method refers to a specific strategy for analyzing and processing data developed during the system design phase. For example, a Kalman filter algorithm is used as a preset method to reduce the impact of noise on vibration data analysis, thereby improving the shock absorption effect.

[0067] The beneficial effects of the above technical solution are: through the integration of light collection and vibration monitoring, intelligent light tracking and dynamic vibration reduction of photovoltaic panels are realized, sensors are used to obtain light and vibration information in real time, the bracket angle is automatically adjusted to optimize light absorption, and vibration data is effectively analyzed. Vibration reduction measures are implemented, which significantly improves the stability and power generation efficiency of the photovoltaic system in complex environments, and has strong intelligence and adaptability.

[0068] Example 2

[0069] The embodiment of the present invention provides an intelligent tracking and vibration reduction system for a photovoltaic bracket, a light collection module, including:

[0070] Intensity determination unit: a preset light sensor group is arranged on the top of the bracket to collect real-time light intensity information;

[0071] Variable determination unit: detects the change data of light intensity by a preset light intensity sensor and converts the data into variable data information;

[0072] Angle determination unit: detects the altitude angle and azimuth angle of the sun based on a preset angle sensor.

[0073] In this embodiment, the preset light sensor group refers to a group of sensors that have been determined and installed in the system design stage, which are used to measure light intensity, for example, multiple light sensors (such as photoresistors and photodiodes) installed on the top of the photovoltaic bracket are used to obtain light intensity information at different angles;

[0074] In this embodiment, the real-time light intensity information refers to the light intensity data collected by the sensor at the current moment. For example, the light intensity fed back by the sensor in real time is 800 lux, indicating the light intensity of the environment at that moment.

[0075] In this embodiment, the preset light intensity sensor refers to a sensor for detecting light intensity that is selected and fixedly installed during the system design stage. For example, a photoelectric sensor is used as the preset light intensity sensor to ensure that changes in ambient light are accurately captured;

[0076] In this embodiment, the light intensity change data refers to the light intensity change recorded over a period of time, for example, the light intensity changes from 600 lux to 750 lux within 10 seconds, and this data can be used to analyze light fluctuations;

[0077] In this embodiment, variable data information refers to converting the light intensity change data into numerical information that can be used for further calculation and analysis. For example, the light intensity change data is processed as "the light increment is 150 lux" to facilitate subsequent judgment of the need for light tracking adjustment.

[0078] In this embodiment, the preset angle sensor refers to a sensor determined and installed during the system design phase for measuring the solar altitude angle and azimuth angle. For example, a tilt sensor and an azimuth sensor are used as preset angle sensors to provide real-time sun position data to help adjust the angle of the photovoltaic panel.

[0079] The beneficial effects of the above technical solution are: efficient light data collection is achieved through a multi-sensor layout, light intensity is monitored in real time through the light sensor on the top of the bracket, basic data is provided for subsequent adjustments, light changes are converted into variable data, the system's sensitivity to environmental changes is enhanced, and preset angle sensors are used to accurately detect the sun's altitude and azimuth, providing key inputs for intelligent tracking, thereby improving the photovoltaic bracket's ability to adapt to lighting conditions and significantly improving power generation efficiency and the system's intelligence level.

[0080] Example 3

[0081] The embodiment of the present invention provides an intelligent tracking and damping system for a photovoltaic bracket, and a light tracking adjustment module, including:

[0082] Coefficient determination unit: Determines the angle coefficient of the bracket based on real-time lighting information:

[0083]

[0084] Where k is the angle coefficient of the bracket, I is the real-time light intensity, and I max is the preset maximum light intensity, θ h is the altitude angle of the sun relative to the horizon, θ a is the azimuth angle of the sun relative to the photovoltaic panel, H is the preset environmental attenuation coefficient, D is the preset distance attenuation coefficient, F is the efficiency factor of the photovoltaic panel, and τ is the preset time attenuation coefficient.

[0085] Parameter conversion unit: converts the angle coefficient of the bracket into specific control motion parameters;

[0086] Angle adjustment unit: converts the motion parameters of the motor into control instructions based on a preset method, starts the control device according to the sent control instructions, and adjusts the angle of the bracket;

[0087] The intelligent light-chasing unit determines whether the bracket is adjusted to the target position based on the preset light-chasing algorithm. If the target angle is not reached, it continues to adjust until the preset target is reached.

[0088] In this embodiment, the preset environmental attenuation coefficient refers to a coefficient determined in the design stage to indicate the degree of attenuation of light intensity due to environmental factors (such as haze, shadow, etc.). For example, the preset environmental attenuation coefficient is 0.8, which means that under certain environmental conditions, the light intensity is only 80% of the ideal value;

[0089] In this embodiment, the preset distance attenuation coefficient refers to a coefficient used to describe the degree to which the light intensity attenuates with distance. For example, the preset distance attenuation coefficient is 0.9, which means that the light intensity will decrease by 10% for every 1 meter increase in distance.

[0090] In this embodiment, the efficiency factor of the photovoltaic panel refers to the efficiency ratio of the photovoltaic panel in converting the received light into electrical energy. For example, the efficiency factor of the photovoltaic panel is 0.18, which means that the photovoltaic panel can convert 18% of the received light energy into electrical energy.

[0091] In this embodiment, the preset time attenuation coefficient refers to a coefficient used to indicate the degree to which the light intensity may attenuate over time. For example, the preset time attenuation coefficient is 0.95, indicating that the light intensity may decay to 95% of the original intensity after one hour.

[0092] In this embodiment, the control instruction refers to an instruction for instructing the control device to perform a specific action, for example, a control instruction of "adjusting the angle of the bracket to 30 degrees" instructs the motor to rotate the bracket to a target angle at a specific speed;

[0093] In this embodiment, the preset target refers to the ideal angle or position that the photovoltaic panel should achieve, which is set during the system design phase. For example, the preset target is that the optimal angle between the photovoltaic panel and the sun is 45 degrees to ensure the best light reception effect.

[0094] The beneficial effects of the above technical solution are: the angle coefficient of the bracket is dynamically determined through real-time lighting information, the light-chasing ability of the photovoltaic bracket is optimized, the optimal angle is calculated according to multiple environmental factors, and the photovoltaic panel is ensured to receive sunlight in the optimal position. The angle coefficient is converted into motor control parameters, and the angle adjustment unit generates precise control instructions, starts the adjustment mechanism, and continuously monitors the bracket position to ensure that it is quickly and accurately adjusted to the target angle, thereby improving the efficiency and adaptability of photovoltaic power generation and effectively enhancing the intelligence level of the system.

[0095] Example 4

[0096] The embodiment of the present invention provides an intelligent tracking and vibration reduction system for a photovoltaic bracket, and a parameter conversion unit, comprising:

[0097] Angle determination subunit: Determine the target tilt angle of the bracket based on the angle coefficient. At the same time, determine the target rotation angle of the bracket according to the solar illumination information and the initial position of the photovoltaic bracket, and then determine the tilt angle and rotation angle:

[0098] Δθ=θ h -arccos(k)-θ curreny

[0099] Δφ=(θ a -φ current +360°)mod360°

[0100] Among them, Δθ is the tilt angle of the bracket, Δφ is the rotation angle of the bracket, and θ h is the altitude angle of the sun relative to the horizon, θ a is the azimuth of the sun relative to the photovoltaic panel, k is the angle coefficient of the bracket, θ current is the current tilt angle of the bracket, φ current is the current rotation angle of the bracket;

[0101] Direction determination subunit: Determine the rotation direction based on the rotation angle. If Δθ>0, it tilts clockwise, otherwise it rotates counterclockwise. If Δφ>0, it rotates clockwise, otherwise it rotates counterclockwise.

[0102] The time determination subunit determines the rotation time based on the rotation angle and the preset support rotation speed;

[0103] Parameter determination subunit: determines the rotation angle, direction, preset bracket speed and rotation time as the motion parameters of the motor.

[0104] In this embodiment, the target tilt angle refers to the ideal tilt angle of the photovoltaic panel set for optimal light reception during the photovoltaic bracket adjustment process. Assuming that the altitude angle of the sun is 45 degrees and the angle coefficient of the bracket is 1.2, then through calculation, the target tilt angle may be set to 54 degrees (45 degrees × 1.2) to ensure that the photovoltaic panel can better capture sunlight;

[0105] In this embodiment, the target rotation angle refers to the angle that the photovoltaic bracket should be adjusted relative to its initial position to ensure that the photovoltaic panel always faces the sun. If the current rotation angle is 30 degrees, and the azimuth angle of the sun changes and needs to be rotated to 60 degrees, the target rotation angle is 30 degrees (target 60 degrees - current 30 degrees). This indicates that the bracket needs to be adjusted by 30 degrees to maintain optimal light reception.

[0106] The beneficial effects of the above technical solution are: by accurately calculating the inclination and rotation angles of the photovoltaic bracket, intelligent tracking of sunlight is achieved, the altitude and azimuth of the sun are comprehensively considered to ensure that the bracket receives sunlight at the optimal angle, and the rotation direction is flexibly adjusted. The time determination subunit optimizes the rotation duration, converts all motion parameters into motor control signals, improves the tracking efficiency and response speed of the bracket, and significantly enhances the performance and energy utilization of photovoltaic power generation.

[0107] Example 5

[0108] The embodiment of the present invention provides an intelligent tracking and vibration reduction system for a photovoltaic bracket, a vibration collection module, including:

[0109] Node acquisition unit: perform structural analysis on the support structure to obtain several key nodes;

[0110] Type acquisition unit: analyzes each key node to determine the node type of each key node;

[0111] Node deployment unit: based on the preset node type-sensor type, obtains the preset sensor type to be deployed at each key node, and then deploys the corresponding preset sensor at each key node.

[0112] In this embodiment, structural analysis refers to the evaluation of the physical properties and stress conditions of the photovoltaic bracket to identify key points that may affect its stability and performance. For example, during the analysis process, engineers use finite element analysis to find the stress concentration points of the bracket under the action of wind and identify several key nodes. These nodes are the parts of the bracket structure that need to be monitored most.

[0113] In this embodiment, the node type refers to the classification of the nodes according to their functions and stress conditions in structural analysis to facilitate the selection of appropriate monitoring methods. For example, the key nodes of a photovoltaic bracket may be classified as "bearing nodes", "connection nodes" or "support nodes", and each type of node has different characteristics in bearing capacity and function.

[0114] In this embodiment, the preset node type-sensor type refers to selecting and configuring suitable sensors for specific types of key nodes during the design phase to achieve accurate monitoring. If a "bearing node" is determined to be a key node type, the preset sensor type may be a strain sensor for real-time monitoring of its bearing capacity; and a "connection node" may be equipped with an acceleration sensor to detect vibration conditions.

[0115] The beneficial effects of the above technical solution are: through structural analysis and node type identification, accurate monitoring of key nodes of photovoltaic brackets is achieved. After extracting structural key points, the type acquisition unit determines the functional characteristics of each node, thereby ensuring the targeted deployment of sensors. The deployment optimizes the sensor configuration, enhances the comprehensiveness and accuracy of data collection, and improves the system's real-time response capability to bracket vibration, providing reliable data support for subsequent shock absorption strategies, and significantly improving the safety and stability of photovoltaic equipment.

[0116] Example 6

[0117] An embodiment of the present invention provides an intelligent tracking and vibration reduction system for a photovoltaic bracket, comprising:

[0118] Key nodes, including: connection points, support structure nodes, rotation joint nodes, and fixed point nodes;

[0119] Preset sensors include: acceleration sensor, gyroscope, strain sensor, accelerometer array and vibration sensor.

[0120] In this embodiment, the connection point is the connection part between the bracket and the photovoltaic panel or other components, which bears the function of transmitting force. For example, the connection point between the bottom of the photovoltaic bracket and the ground bears the transmission of gravity and wind force;

[0121] In this embodiment, the support structure node is a support structure inside the bracket that provides stability and strength, for example, a cross support point in the middle of the bracket that can effectively disperse the load applied to the structure;

[0122] In this embodiment, the rotation joint node allows the bracket to rotate in a specific direction, which is usually used to track the movement of the sun. For example, the rotation joint between the top of the bracket and the photovoltaic panel can adjust the tilt angle of the photovoltaic panel according to the position of the sun;

[0123] In this embodiment, the fixed point node provides fixed support to ensure that the bracket does not move under the action of external force. For example, the fixed point between the bottom of the bracket and the foundation is ensured to be stable by bolts or the like.

[0124] In this embodiment, the preset sensors are monitoring devices selected for specific types of key nodes, which are used to obtain structural status and environmental information in real time, including: acceleration sensor: used to measure the acceleration changes of the bracket in different directions, helping to monitor vibration conditions, for example, installed on the supporting structure node to monitor the bracket's response to wind or earthquake, gyroscope: measures the angular velocity and direction changes of the bracket to help maintain its stability, for example, installed at the rotating joint node to ensure that the photovoltaic panel always faces the sun, strain sensor: monitors the deformation of the bracket material to ensure that it works within the bearing capacity, for example, installed at the connection point to detect strain caused by gravity or wind, accelerometer array: composed of multiple accelerometers, providing more comprehensive vibration monitoring, for example, arranged at different positions of the bracket to obtain vibration patterns in real time to ensure structural safety, vibration sensor: specifically monitors the vibration frequency and amplitude of the bracket to identify potential faults, for example, installed at the fixed point node to monitor whether abnormal vibration occurs after long-term operation.

[0125] The beneficial effects of the above technical solution are: through the design of key nodes and the combination of multiple sensors, comprehensive monitoring and analysis of the vibration of photovoltaic brackets are achieved. Various sensors work together to capture the dynamic changes and vibration characteristics of the brackets in real time, ensure the accuracy and reliability of the data, and optimize the real-time adjustment capability of the shock absorption strategy, thereby improving the seismic performance and overall stability of the brackets, and significantly enhancing the operating safety and efficiency of photovoltaic equipment in harsh environments.

[0126] Example 7

[0127] The embodiment of the present invention provides an intelligent tracking and shock absorption system for a photovoltaic bracket, and a shock absorption realization module, including:

[0128] Coefficient determination unit: Analyze the vibration data to determine the vibration coefficient:

[0129]

[0130] Y is the vibration coefficient, α max is the preset maximum vibration acceleration, g is the preset gravity acceleration, f r is the vibration-related frequency factor, n is the vibration damping coefficient of the bracket, δ is the vibration enhancement factor, β is the temperature influence coefficient, T e is the ambient temperature;

[0131] A first strategy determination unit: determining whether the vibration coefficient exceeds a preset basic vibration coefficient threshold value, and if so, determining a corresponding basic shock absorption strategy in a preset coefficient-basic shock absorption strategy database based on the vibration coefficient;

[0132] The second strategy determination unit is configured to determine whether the vibration coefficient exceeds a preset high-intensity vibration coefficient threshold value, and if so, determine a corresponding high-intensity shock reduction strategy in a preset coefficient-high-intensity shock reduction strategy database based on the vibration coefficient;

[0133] Shock absorption optimization unit: Continuously monitors the vibration data of the bracket, and adjusts the shock absorption parameters of the shock absorption strategy in real time based on the vibration data to form a closed-loop control.

[0134] In this embodiment, the vibration coefficient is a value calculated by analyzing the vibration data, which reflects the vibration intensity of the bracket under specific conditions. If the vibration acceleration monitored by the sensor is 5m / s 2 , and the acceleration due to gravity is 9.8m / s 2 , then the vibration coefficient may be defined as their ratio, which represents the vibration effect on the bracket;

[0135] In this embodiment, the preset maximum vibration acceleration is a threshold value set by the system. Exceeding this value may cause damage to the support structure. Assume that the preset maximum vibration acceleration is 6m / s 2 , when the monitored acceleration exceeds this value, the system will automatically initiate shock absorption measures to protect the bracket;

[0136] In this embodiment, the vibration-related frequency factor refers to a parameter related to the vibration frequency and is used to analyze the characteristics of the vibration. For example, if the bracket resonates at a specific frequency, the frequency factor may be set to a multiple of the frequency to identify potential resonance problems;

[0137] In this embodiment, the vibration damping coefficient refers to the energy absorption capacity of the bracket material and structure to vibration, reflecting its shock absorption effect. If the damping coefficient of the bracket is 0.5, it means that the bracket can effectively absorb 50% of the vibration energy when vibrating, thereby reducing the vibration amplitude;

[0138] In this embodiment, the temperature influence coefficient takes into account the impact of ambient temperature changes on the vibration characteristics and material properties of the bracket. For example, when the temperature rises, the stiffness of the material may decrease, so the preset temperature influence coefficient may be set to 1.2 to adjust the vibration calculation.

[0139] In this embodiment, the preset basic vibration coefficient threshold is the minimum safe vibration coefficient value set by the system, which is used to judge normal and abnormal states. If the preset basic vibration coefficient threshold is 2.0, when the calculated vibration coefficient is 2.5, the system will consider the vibration normal. If it is lower than 2.0, it is considered that measures need to be taken.

[0140] In this embodiment, the preset high-intensity vibration coefficient threshold is a set high-risk vibration coefficient. Exceeding this value indicates that the bracket is in a dangerous state and immediate measures need to be taken. Assuming that the preset high-intensity vibration coefficient threshold is 4.0, when the vibration coefficient is monitored to be 4.5, the system will trigger an alarm and execute a high-intensity shock absorption strategy.

[0141] In this embodiment, the shock absorption parameters refer to various parameters used to adjust and optimize the shock absorption strategy to achieve a more effective shock absorption effect, including the damping coefficient of the bracket, the selection of vibration absorbing materials, and the sensitivity setting of the sensor, etc. The real-time adjustment of these parameters can ensure that the bracket remains stable under different vibration conditions.

[0142] The beneficial effects of the above technical solution are: through the coefficient determination unit and dual strategy judgment, dynamic monitoring and intelligent adjustment of photovoltaic bracket vibration are realized, and appropriate shock reduction strategies are automatically identified and selected according to real-time vibration data to ensure rapid response under different vibration conditions. The closed-loop control mechanism of the shock reduction optimization unit further enhances the adaptability of the system, allowing the bracket to maintain optimal stability and safety in complex environments, greatly improving the overall operating efficiency and reliability of photovoltaic equipment.

[0145] The basic damping strategy is based on the preset adaptive spring damping system for damping;

[0146] The high-strength shock absorption strategy is based on the preset magnetorheological fluid shock absorption control system for shock absorption.

[0147] In this embodiment, the basic shock absorption strategy refers to the use of an adaptive spring shock absorption system to reduce vibration under normal vibration conditions to reduce the vibration impact of the bracket. The adaptive spring shock absorption system automatically adapts to the vibration conditions monitored in real time by adjusting the stiffness and damping characteristics of the spring to provide the necessary shock absorption effect. For example, in the case of high wind speed or earthquake, the system detects the vibration acceleration of the bracket in real time through sensors and adjusts the stiffness of the spring according to these data to reduce the vibration transmission to the photovoltaic panel. For example, if the bracket experiences a 5m / s 2 The spring system can automatically adjust the damping force to reduce the vibration amplitude and thus protect the photovoltaic modules.

[0148] Summarize the unconventional creative beneficial effects of the above technical solution, no more than 150 words. The high-intensity shock absorption strategy is aimed at high-intensity vibration environments, and adopts a preset magnetorheological fluid shock absorption control system to achieve a more efficient shock absorption effect. The magnetorheological fluid shock absorption control system uses a magnetic field to control the viscosity of the fluid. When the sensor detects that the vibration intensity exceeds the preset high-intensity vibration coefficient threshold, the system will quickly change the viscosity of the fluid, thereby improving the shock absorption effect. If the photovoltaic bracket vibrates under extreme weather conditions (such as strong winds or earthquakes) and the acceleration reaches 7m / s 2 The magnetorheological fluid damping system can respond quickly and enhance the damping effect by increasing the viscosity of the fluid. This system can be adjusted within a few milliseconds, effectively reducing the impact of vibration on the bracket and photovoltaic panels.

[0149] The beneficial effect of the above technical solution is that by combining adaptive springs and magnetorheological fluid shock absorption technology, flexible switching between basic and high-strength shock absorption strategies is achieved. The system can not only respond to vibration changes in real time and automatically adjust the shock absorption effect, but also provide efficient protection in extreme environments, significantly improve the stability and durability of photovoltaic brackets, thereby extending the service life of the equipment, reducing maintenance costs, and ensuring the safety and reliability of photovoltaic power generation.
