[0002] During satellite operation, the solar array, as an important energy acquisition component, directly affects the satellite's energy conversion efficiency and operational stability through the accuracy of its attitude adjustment. Furthermore, target satellites often need to be equipped with multiple information acquisition devices and use these devices to collect different types of information for solar array attitude adjustment in order to ensure the accuracy of the calculated position and angle of the solar array and maximize energy output.

[0003] However, traditional solar panel attitude adjustment methods rely excessively on the stability and accuracy of information acquisition equipment. When one or more of the information acquisition equipment suffers from reduced sensitivity due to prolonged operation or external negative factors, the accuracy of the acquired information decreases, thereby affecting the energy conversion efficiency of the solar panel.

Detailed Implementation

[0033] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] This application provides a method for adjusting the solar attitude of a solar array, which can be executed by an electronic device. The electronic device can be a server, which can be an independent physical server, a server cluster composed of multiple physical servers, or a distributed device, or a cloud server that provides cloud computing services. The server can be installed on a low-Earth orbit satellite or a high-Earth orbit satellite.

[0036] Reference Figure 1 A method for adjusting the solar wing's attitude towards the sun includes steps S101, S102, S103, and S104, wherein...

[0037] S101, if the energy output corresponding to the target satellite's orbital position point is not within the preset energy output range, acquire the target satellite's solar array's target attitude information and the historical attitude information of the previous operating cycle adjacent to the current operating cycle.

[0038] In some embodiments, the preset orbital position point is a specific position point subjectively set by technicians in the target satellite's orbit; the energy output is the amount of energy generated by the target satellite's solar array within a preset unit time period; the target solar attitude information is the information collected by the information acquisition equipment installed on the target satellite when the target satellite is at the preset orbital position point, used to determine the position and angle adjustment of the solar array; the historical solar attitude information is the information collected by the information acquisition equipment installed on the target satellite when the target satellite is at the preset orbital position point in the previous operating cycle, used to determine the position and angle adjustment of the solar array.

[0039] The electronic equipment monitors the target satellite's operation in real time. When the target satellite reaches a preset orbital position, the electronic equipment generates an information acquisition command and sends it to the target satellite. The target satellite responds to the command by transmitting its autonomously monitored energy output to the electronic equipment. The electronic equipment compares the acquired energy output with a preset energy output range. This preset range is based on the historical energy output of the preceding operational cycle adjacent to the current energy output; that is, it uses this historical energy output as a benchmark to set the minimum and maximum values ​​of the preset energy output range.

[0040] If the electronic equipment determines that the energy output is not within the preset energy output range, it indicates that when the target satellite moves to the preset orbital position, the energy output of its solar array fluctuates significantly compared to the energy output of the previous operating cycle. This suggests that the sensitivity of the information acquisition equipment installed on the target satellite may be reduced, thus affecting the position and angle adjustment of the solar array. Subsequently, the electronic equipment acquires the target satellite's solar array's target attitude information and the historical attitude information of the previous operating cycle adjacent to the current operating cycle.

[0041] S102, based on the target's attitude information toward the sun and historical attitude information toward the sun, determine the initial attitude adjustment information.

[0042] In some embodiments, the target attitude information to the sun includes multiple sub-target attitude information to the sun, the historical attitude information to the sun includes multiple sub-historical attitude information to the sun, a certain sub-target attitude information to the sun corresponds to a certain sub-historical attitude information to the sun and a certain acquisition device among multiple information acquisition devices installed on the target satellite; the initial attitude adjustment information is a certain sub-target attitude information to the sun or a part of the sub-target attitude information to the sun among the multiple sub-target attitude information to the sun.

[0043] The electronic device compares and analyzes the target's attitude information relative to the sun with historical attitude information relative to the sun to determine the information deviation between the target's attitude information relative to the sun and historical attitude information relative to the sun. Based on the information deviation, it selects the initial attitude adjustment information from the multiple sub-target attitude information relative to the sun contained in the target's attitude information relative to the sun.

[0044] S103, determine multiple historical attitude adjustment information corresponding to the initial attitude adjustment information, and determine the target attitude adjustment information based on the multiple historical attitude adjustment information.

[0045] In some embodiments, the multiple historical attitude adjustment information are information collected by the information acquisition equipment installed on the target satellite during different historical operating cycles, corresponding to the initial attitude adjustment information, for adjusting the position and angle of the solar array; the target attitude adjustment information is information determined by comparing and calculating multiple historical attitude adjustment information to replace the initial attitude adjustment information.

[0046] The electronic device acquires multiple first historical attitude adjustment information, analyzes and preliminarily filters the multiple first historical attitude adjustment information to obtain multiple second historical attitude adjustment information. Subsequently, the electronic device performs calculation and secondary filtering based on the multiple second attitude adjustment information to determine the target attitude adjustment information.

[0047] S104: Based on the target attitude adjustment information and the target attitude towards the sun information, determine the final attitude towards the sun information, and control the solar array to adjust its attitude based on the final attitude towards the sun information.

[0048] In some embodiments, the final solar attitude information is parameter information for adjusting the position and angle of the target satellite's solar array.

[0049] After determining the target attitude information, the electronic equipment filters out the attitude adjustment information corresponding to the target attitude adjustment information from the target attitude information, and replaces the attitude adjustment information with the target attitude adjustment information to obtain the new target attitude information, i.e., the final attitude information. Subsequently, the electronic equipment determines the adjustment control information of the position and angle of the solar array based on the final attitude information and sends the adjustment control information to the target satellite.

[0050] The target satellite responds to adjustment and control information, controlling the solar array to adjust its attitude. By filtering out the attitude adjustment information with large deviations from the attitude adjustment information corresponding to multiple different information acquisition devices, and replacing it with historical attitude adjustment information, the final attitude adjustment information is used to calculate the adjustment and control information again. This reduces the possibility of reduced sensitivity of one or more information acquisition devices, which could lead to a decrease in the accuracy of the information acquired by those devices, thereby improving the energy conversion efficiency of the target satellite's solar array.

[0051] In some embodiments, when the target attitude information includes multiple sub-target attitude information, the historical attitude information includes multiple sub-historical attitude information, and there is a correspondence between the multiple sub-target attitude information and the multiple sub-historical attitude information, step S102, determining initial attitude adjustment information based on the target attitude information and the historical attitude information, includes: determining multiple information deviations based on the multiple sub-target attitude information and the multiple sub-historical attitude information; comparing the multiple information deviations with preset information deviations respectively; and determining the sub-target attitude information corresponding to any information deviation as the initial attitude adjustment information when any information deviation is greater than the preset information deviation.

[0052] In some embodiments, there is a one-to-one correspondence between multiple sub-target attitude information and multiple sub-historical attitude information, and a certain sub-target attitude information and a certain sub-historical attitude information with a one-to-one correspondence are collected by the same information acquisition device; then the electronic device compares and analyzes the sub-target attitude information and the sub-historical attitude information with a one-to-one correspondence to determine the amount of information deviation between the two.

[0053] Subsequently, the electronic device compares the obtained multiple information deviations with the preset information deviations. If any of the multiple information deviations is greater than the preset information deviation, it indicates that the sub-target attitude information corresponding to any information deviation has changed significantly compared to its corresponding historical attitude information, and there is a possibility that the sensitivity of the information acquisition device has decreased. Then, the electronic device determines the sub-target attitude information corresponding to any information deviation as the initial attitude adjustment information.

[0054] In step S103, determining multiple historical attitude adjustment information corresponding to the initial attitude adjustment information includes: acquiring first historical attitude adjustment information corresponding to a preset number of operating cycles adjacent to the target satellite and event information corresponding to the first historical attitude adjustment information; performing preliminary screening on the multiple first historical attitude adjustment information based on the event information to obtain multiple second historical attitude adjustment information; determining the average historical attitude adjustment information based on the multiple second historical attitude adjustment information, and screening the multiple second historical attitude adjustment information based on the average historical attitude adjustment information to obtain multiple historical attitude adjustment information.

[0055] In some embodiments, the electronic device obtains from the storage device the first historical attitude adjustment information and the event information corresponding to the first historical attitude adjustment information for a preset number of adjacent operating cycles of the target satellite in the past operation. The first historical attitude adjustment information and the initial attitude adjustment information are collected by the same information acquisition device, and the event information is information reflecting the operating status of the target satellite in its environment when it obtains the first historical attitude adjustment information.

[0056] Subsequently, the electronic device compares multiple event information with preset event information, discards the first historical attitude adjustment information corresponding to event information that is inconsistent with the preset event information, and retains the first historical attitude adjustment information corresponding to event information that is consistent with the preset event information, and determines it as the second historical attitude adjustment information.

[0057] The electronic device will obtain multiple historical attitude adjustment information and calculate the average value to obtain the average historical attitude adjustment information. Then, the electronic device will determine the range of the average historical attitude adjustment information based on the average historical attitude adjustment information and compare multiple second historical attitude adjustment information with the range of the average historical attitude adjustment information. Subsequently, the electronic device will determine the second historical attitude adjustment information that is within the range of the average historical attitude adjustment information as the historical attitude adjustment information, and thus obtain multiple historical attitude adjustment information.

[0058] In step S103, the target attitude adjustment information is determined based on multiple historical attitude adjustment information, including: determining the mean historical attitude adjustment information corresponding to the multiple historical attitude adjustment information; comparing the multiple historical attitude adjustment information with the mean historical attitude adjustment information respectively; and determining the historical attitude adjustment information with the smallest difference from the mean historical attitude adjustment information among the multiple historical attitude adjustment information as the target attitude adjustment information.

[0059] In some embodiments, the electronic device calculates the average of multiple historical attitude adjustment information to obtain the corresponding average historical attitude adjustment information. Then, the electronic device compares the multiple historical attitude adjustment information with the average historical attitude adjustment information, selects the historical attitude adjustment information with the smallest difference from the average historical attitude adjustment information from the multiple historical attitude adjustment information, and determines the historical attitude adjustment information as the target attitude adjustment information.

[0060] In some embodiments, the sub-target attitude information, sub-historical attitude information, historical attitude adjustment information, and target attitude adjustment information are all parameter values ​​collected by the information acquisition device. These parameter values ​​are used to calculate and control the position and angle of the solar array.

[0061] In step S104, the final attitude information for the sun is determined based on the target attitude adjustment information and the target attitude information for the sun, including: discarding the sub-target attitude information for the sun that corresponds to the target attitude adjustment information in the target attitude information for the sun, and obtaining partial target attitude information for the sun; and determining the final attitude information for the sun based on the preset attitude parameter determination rules, the partial target attitude information for the sun, and the target attitude adjustment information.

[0062] In some embodiments, the electronic device filters out the sub-target attitude information corresponding to the target attitude adjustment information from multiple sub-target attitude information in the target attitude adjustment information, and discards the sub-target attitude information to obtain partial target attitude information. Subsequently, the electronic device integrates the partial target attitude information and the target attitude adjustment information, and calls the preset attitude parameter determination rules to calculate the parameter information used to adjust the position and angle of the solar array of the target satellite, that is, the final attitude information.

[0063] In some embodiments, after controlling the solar array to adjust its attitude based on the final solar attitude information, the above-described method for adjusting the solar array's attitude further includes: obtaining the target energy output corresponding to the solar array, and determining the energy output range based on the energy output; comparing the target energy output and the energy output range; generating a mode continuous execution command and equipment sensitivity reduction information when the target energy output is greater than the upper limit of the energy output range; and generating a mode interruption execution command and equipment normal operation information when the target energy output is within the energy output range.

[0064] In some embodiments, after the target satellite adjusts its solar array attitude based on the final solar attitude information obtained from the electronic device, the solar array performs energy conversion based on the adjusted state. The electronic device monitors the energy output of the target satellite's solar array in real time, that is, obtains the target energy output corresponding to the sun. The preset time period corresponding to the target energy output is equal to the preset time period of the energy output. Subsequently, the electronic device compares the target energy output with the energy output range, wherein the energy output range is set based on the energy output.

[0065] If the electronic equipment determines that the target energy output exceeds the energy output range, it indicates that one or more of the information acquisition devices installed on the target satellite have reduced sensitivity. Therefore, the electronic equipment generates a mode-continuous execution command and equipment sensitivity reduction information, and sends the mode-continuous execution command to the target satellite. This allows the target satellite to continue determining its attitude information for the next operating cycle based on the method used to determine the final attitude information for the sun. The electronic equipment also sends the equipment sensitivity reduction information to the ground control center to inform ground technicians that the target satellite has a problem with reduced sensitivity in its information acquisition devices.

[0066] When the electronic equipment determines that the target energy output is within the energy output range, it indicates that after adjusting the solar array based on the final solar attitude information, its energy output does not change significantly compared to adjusting the solar array based on the solar attitude information obtained by the information acquisition equipment. There is no issue of reduced sensitivity of the information acquisition equipment. Subsequently, the electronic equipment generates a mode interruption execution command and normal equipment information, and sends the mode interruption execution command to the target satellite, enabling the target satellite to continue adjusting the solar array based on the information obtained by the information acquisition equipment, and to send the normal equipment information to the ground control center.

[0067] In some embodiments, when the initial attitude adjustment information includes multiple initial attitude adjustment information, after determining the initial attitude adjustment information based on the target solar attitude information and historical solar attitude information in step S102, the above-described method for adjusting the solar wing's solar attitude further includes: determining a first number of multiple sub-target solar attitude information included in the target solar attitude information and a second number corresponding to the multiple initial attitude adjustment information; when the second number is less than the first number and the second number is greater than half of the first number, generating equipment fault information and historical data retrieval instructions, and controlling the target satellite's information acquisition equipment to stop operating based on the equipment fault information, and controlling the target satellite's solar wings to perform attitude adjustment based on the historical data retrieval instructions.

[0068] In some embodiments, when there are multiple initial state adjustment information, it indicates that multiple information acquisition devices may have reduced sensitivity. The more information acquisition devices with reduced sensitivity, the less meaningful it is to use the information acquisition devices to collect information for adjusting the solar array. Therefore, the electronic device determines a first number of multiple sub-target solar attitude information and a second number corresponding to multiple initial attitude adjustment information, which are included in the target's solar attitude information. Subsequently, the electronic device compares the first number and the second number. If it determines that the second number is less than the first number and the second number is greater than half of the second number, it indicates that more than half of the information acquisition devices may have reduced sensitivity. Then, the electronic device generates device fault information and historical data retrieval instructions, and sends the device fault information to the target satellite, causing the target satellite to control the information acquisition devices to stop operating, thereby reducing the energy consumption of the information acquisition devices. Based on the historical data retrieval instructions, the electronic device retrieves the solar attitude information of the target satellite in previous operating cycles and adjusts the attitude of the solar array based on the solar attitude information.
