[0050] To facilitate understanding of this embodiment, a low-orbit satellite communication method based on a photovoltaic power generation device disclosed in an embodiment of the present invention is first introduced in detail, wherein the photovoltaic power generation device is integrated with a satellite receiving device. Figure 1 As shown, the method comprises the following steps:

[0051] 101. During the operation of photovoltaic power generation equipment, light energy is collected and low-orbit satellite signals are detected through satellite receiving equipment;

[0052] In one embodiment of the present invention, the low-orbit satellite communication method based on photovoltaic power generation equipment first needs to realize the process of light energy collection and satellite signal detection. Specifically, the photovoltaic power generation equipment absorbs sunlight through a solar cell array, and the solar cell array is composed of multiple photovoltaic units connected in series and parallel. When light shines on the surface of the solar cell, the photon excites the electron to form an electron-hole pair. Under the action of the built-in electric field, the electron and the hole separate and move in opposite directions, thereby forming a potential difference between the two poles of the battery and generating a photocurrent. The power management unit in the photovoltaic power generation equipment collects the photocurrent, adjusts the working point of the photovoltaic unit in real time through the maximum power point tracking technology, converts the light energy into electrical energy and stores it. At the same time, the intelligent power regulation system dynamically adjusts the photovoltaic output according to the real-time lighting conditions, optimizes the power conversion process while ensuring sufficient power output through an adaptive algorithm, and the built-in electromagnetic interference monitoring device continuously measures the electromagnetic radiation level of each part of the system. When the interference level is detected to exceed the preset threshold, the power conversion frequency is automatically adjusted or switched to a low interference mode to ensure the normal operation of the system.

[0053] Specifically, while collecting light energy, the satellite receiving device receives signals from low-orbit satellites through an antenna array. The satellite receiving device first scans the available satellite signal frequency bands and records the signal strength and signal-to-noise ratio of different frequency bands. By performing spectrum analysis on the received signal, the specific frequency components belonging to the low-orbit satellite are identified. The signal detection process uses a combination of threshold comparison and correlation detection to set an appropriate detection threshold to extract and compare the amplitude, phase and frequency characteristics of the received signal. In the signal detection process, considering the rapid movement characteristics of low-orbit satellites, it is necessary to compensate for the influence of Doppler shift. The satellite receiving device dynamically updates the frequency of the local oscillator by calculating the frequency offset of the received signal to maintain synchronous detection of the signal. In this process, the satellite receiving device also needs to perform preliminary decoding and frame synchronization on the signal to verify the validity of the signal and prepare for the establishment of subsequent communication links.

[0054] 102. When a satellite signal is detected, the operating parameters of the photovoltaic power generation equipment are dynamically adjusted according to the electric energy data collected by the light energy and the low-orbit satellite signal, and the low-orbit satellite corresponding to the satellite signal is locked based on the operating parameters to achieve a stable satellite communication link, wherein the operating parameters include the direction and angle of the photovoltaic power generation equipment and the dynamic power supply strategy of the photovoltaic power generation equipment;

[0055] In one embodiment of the present invention, when a satellite signal is detected, dynamically adjusting the operating parameters of the photovoltaic power generation equipment according to the electric energy data collected by light energy and the satellite signal includes: when a satellite signal is detected, calculating the optimal orientation of the photovoltaic power generation equipment to receive the satellite signal according to the satellite signal, and adjusting the direction and angle of the photovoltaic power generation equipment in real time according to the optimal orientation; calculating the electric energy capacity currently available for satellite communication according to the electric energy data collected by light energy and the strength of the satellite signal, and generating a dynamic power supply strategy for the photovoltaic power generation equipment based on the electric energy capacity, wherein the dynamic power supply strategy includes a real-time power generation power allocation ratio and a battery charging and discharging plan.

[0056] Specifically, when the satellite receiving device detects the satellite signal, it first needs to calculate the optimal orientation of the photovoltaic power generation device based on the satellite signal. Specifically, the satellite receiving device extracts the features of the received satellite signal and obtains the signal feature data through methods such as signal strength measurement and Doppler frequency shift analysis. These signal feature data are input into the preset signal propagation model, which comprehensively considers factors such as signal strength, signal-to-noise ratio, and Doppler frequency shift to calculate the direction of the signal source. Based on the calculated signal source direction, the system further uses the theoretical reception model to determine the optimal orientation of the satellite signal. Subsequently, the system compares the calculated optimal orientation with the current orientation of the photovoltaic power generation device, obtains the orientation difference through vector analysis, and quantifies the difference into specific adjustment parameters. Based on these adjustment parameters, the system generates control instructions for the direction and angle actuators of the photovoltaic power generation device, and the control actuators adjust the direction and angle of the photovoltaic power generation device in real time so that the device orientation is consistent with the calculated optimal orientation. During the adjustment process, the system continuously monitors the reception quality of the satellite signal to ensure the accuracy of the orientation adjustment.

[0057] Specifically, after completing the optimal orientation adjustment, the system begins to process data related to electricity. The system first collects light energy collection data from photovoltaic power generation equipment, including real-time power generation, light intensity, temperature and other parameters, and performs time series analysis on these data to identify the changing trend of light energy collection. At the same time, the system performs multi-threshold grading processing on the satellite signal intensity data, divides the signal strength into different levels, and estimates the expected power consumption required for low-orbit satellite communications based on the communication quality requirements corresponding to different levels. The system balances the predicted power data with the expected power consumption, comprehensively considers the current lighting conditions, battery status and other factors, and derives the current power capacity that can be used for satellite communications. This power capacity data reflects the amount of power that the system can allocate to satellite communications while ensuring basic power generation needs.

[0058] Specifically, based on the calculated available power capacity, the system parameterizes the preset power supply strategy template. In this process, the system first selects the basic strategy template suitable for the current scenario from the template library, and then adjusts and optimizes the parameters in the template according to the actual power capacity and communication requirements. The system also verifies the constraints of the configured power supply strategy to ensure that the strategy meets the various operating requirements of the system. The verified power supply strategy contains two core components: the real-time power generation allocation ratio and the battery charge and discharge plan. Among them, the real-time power generation allocation ratio specifies the allocation scheme of the current power generation between different uses, while the battery charge and discharge plan specifies the battery charge and discharge strategy at different time periods to ensure that the system can continue to operate stably. In this way, a complete dynamic power supply strategy is formed to guide the energy management of photovoltaic power generation equipment.

[0059] Furthermore, when a satellite signal is detected, the optimal orientation of the photovoltaic power generation device to receive the satellite signal is calculated based on the satellite signal, and the direction and angle of the photovoltaic power generation device are adjusted in real time based on the optimal orientation, including: performing signal feature extraction processing on the satellite signal to obtain signal feature data, and inputting the signal feature data into a preset signal propagation model to obtain a signal source direction estimation result; based on the signal source direction estimation result, determining the optimal orientation of the satellite signal, and quantifying the orientation difference based on the optimal orientation and the current orientation of the photovoltaic power generation device to obtain an orientation adjustment parameter; based on the orientation adjustment parameter, generating a control instruction for the direction and angle actuator of the photovoltaic power generation device, and according to the control instruction, controlling the direction and angle actuator to adjust the direction and angle of the photovoltaic power generation device in real time.

[0060] Specifically, in the process of extracting the signal features of the satellite signal and inputting the preset signal propagation model to obtain the signal source direction estimation result, the system first collects the basic characteristic parameters of the satellite signal, such as the intensity, frequency and phase. The signal is analyzed in the time-frequency domain by Fourier transform to extract the spectrum characteristics of the signal. Then, the system performs Doppler frequency shift analysis on the signal and calculates the Doppler frequency shift of the signal. Based on the Doppler frequency shift and signal strength attenuation characteristics, the system establishes a signal propagation path loss model. The expression of the path loss model is:

[0061] ;

[0062] in, The reference distance The path loss at is the path loss exponent, is a shadow fading that obeys Gaussian distribution. Finally, the system calculates the azimuth of the signal source direction through the signal propagation model. and pitch angle In the process of determining the optimal orientation of the satellite signal based on the signal source direction estimation result and quantifying the difference between it and the current orientation of the photovoltaic power generation equipment, the system first calculates the azimuth angle. and pitch angle A space vector model was established. The objective function was optimized by the minimum mean square error criterion, and the formula is:

In the process of generating the direction and angle actuator control instructions of the photovoltaic power generation equipment based on the orientation adjustment parameters, and adjusting the direction of the photovoltaic power generation equipment in real time according to the control instructions, the system first converts the angle correction amount into the motor speed and displacement control amount.

By executing control instructions, the drive motor drives the photovoltaic panel to rotate to the target position, thereby realizing real-time orientation adjustment of the photovoltaic power generation equipment.

[0075] Furthermore, the electric energy data collected by the light energy and the strength of the satellite signal are used to calculate the electric energy capacity currently available for satellite communication, and the dynamic power supply strategy of the photovoltaic power generation equipment is generated based on the electric energy capacity, including: performing time series analysis on the electric energy data collected by the light energy to obtain the electric energy generation trend, and predicting the electric energy generation in the future time window according to the electric energy generation trend to obtain predicted electric energy data; performing multi-threshold grading on the intensity data of the satellite signal to obtain the communication quality level, and estimating the expected power consumption of the low-orbit satellite communication according to the communication quality level; performing balance calculation on the electric energy capacity available for satellite communication according to the predicted electric energy data and the expected power consumption to obtain the electric energy capacity currently available for satellite communication; and performing parameterized configuration processing and constraint verification processing on the preset power supply strategy template based on the currently available electric energy capacity to obtain the dynamic power supply strategy of the photovoltaic power generation equipment.

[0076] Specifically, in the process of analyzing the time series of the electric energy data collected by light energy and predicting the future electric energy generation, the system first analyzes the historical electric energy data series. The system uses an improved deep learning time series prediction model LSTM-Attention model, which combines the influence of weather factors. The prediction model formula is as follows:

Then, the system performs multi-threshold classification processing on the satellite signal strength data to obtain the communication quality level. In order to evaluate the expected power consumption of low-orbit satellite communications, the system proposes a multi-dimensional signal quality evaluation model that comprehensively considers factors such as signal strength, Doppler frequency shift, and atmospheric attenuation. The signal quality formula of this model is:

Subsequently, the system balances the power capacity available for satellite communication based on the predicted power data and expected communication power consumption. The balancing process is achieved through an intelligent control strategy. The system establishes an energy allocation model based on a fuzzy neural network, which is expressed as:

The system evaluates and adjusts the strategy in real time to ensure that energy efficiency is optimized while satisfying various constraints, thereby generating the final dynamic power supply strategy.

[0091] Furthermore, based on the currently available electric energy capacity, the preset power supply strategy template is parameterized and configured and the constraint verification is performed to obtain the dynamic power supply strategy of the photovoltaic power generation equipment, including: comparing and analyzing the currently available electric energy capacity and the predicted electric energy data to obtain the electric energy profit and loss state, and preliminarily allocating the real-time power generation power of the photovoltaic power generation equipment according to the electric energy profit and loss state to obtain an initial power allocation ratio; performing satellite communication demand constraint processing on the initial power allocation ratio to obtain a power allocation scheme that meets the communication demand, and simulating and calculating the battery charging and discharging process according to the power allocation scheme and the current battery power state of the battery of the photovoltaic power generation equipment to obtain a battery charging and discharging plan; fine-tuning the initial power allocation ratio according to the battery charging and discharging plan to obtain the real-time power generation power allocation ratio; performing time series combination processing on the real-time power generation power allocation ratio and the battery charging and discharging plan to obtain a dynamic power supply strategy.

[0092] Specifically, in the process of comparing and analyzing the current available power capacity and the predicted power data, the system first establishes a power balance assessment model by calculating the power difference:
