Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of satellite data processing, in particular to a data processing method and device based on multiple satellites, an electronic device and a medium. BACKGROUND

[0002] Due to the limited data processing capability of low-orbit satellites, in general, low-orbit satellites only undertake data receiving and forwarding communication tasks. However, with the continuous development of low-orbit satellite technology, the number of low-orbit satellites in operation is increasing. In order to better provide communication services, the concept of low-orbit satellites undertaking data processing communication tasks is proposed. Today, there is a technical solution for low-orbit satellites to undertake data processing communication tasks, that is, the communication data to be processed is split, and the split multiple sub-communication data is sent to the corresponding low-orbit satellite for processing. Finally, the processed multiple sub-communication data is integrated, and the integrated communication data is sent.

[0003] However, the applicant of the present application found that in the traditional technical solution of low-orbit satellites undertaking data processing communication tasks, the data splitting rule needs to be determined for each batch of data to be processed, and the data splitting and matching process of the split data with the low-orbit satellite. This results in that when the time period of the collected data is continuous and the data volume of the time period is large, multiple data splitting rules need to be determined, the data needs to be split, and the split data needs to be matched with the low-orbit satellite, thereby causing low efficiency of the low-orbit satellite in processing the data to be processed.

DETAILED DESCRIPTION

[0037] The following will be described in detail in combination with the accompanying drawings Figures 1-3 The application will be further described in detail.

[0038] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0039] The embodiments of the present application provide a multi-satellite-based data processing method, which can be executed by an electronic device. The electronic device can be a server. The server can be a physical server, a server cluster composed of multiple physical servers or a distributed device, or a cloud server providing cloud computing services. The server can be installed on a ground terminal, a high-orbit satellite or a low-orbit satellite.

[0040] Referring to Figure 1 The multi-satellite-based data processing method comprises the following steps: S101, S102, S103 and S104. In S101, a communication task of an initial satellite is acquired, and based on the communication task, an image data processing standard and a target image data volume are determined.

[0041] In some embodiments, the initial satellite is a satellite for performing an image acquisition task of a target monitoring area, which can be a low-orbit satellite. The image data processing standard is a requirement for performing a data processing step on the target data collected by the initial satellite, such as data format inspection, preprocessing, image enhancement, image optimization, spatial alignment and information extraction of the target remote sensing image. The target image data volume is the data volume of the target image acquired when the initial satellite completes the image acquisition of the target monitoring area in a single acquisition period.

[0042] The communication task is a specific requirement of the initial satellite for image acquisition of the target monitoring area, such as an image acquisition area requiring image acquisition, a position to which the initial satellite needs to run for image acquisition of the target monitoring area, an image acquisition type to be used, and a type of final image data obtained after image processing of the acquired image.

[0043] The communication task is subjectively set by a technician and sent to the initial satellite. The electronic device generates a task acquisition instruction and sends it to the initial satellite. The initial satellite responds to the task acquisition instruction and sends the communication task to the electronic device.

[0044] The electronic device determines the image acquisition region corresponding to the initial satellite and the final data form of the target image collected by the initial satellite after processing by analyzing the communication task, and determines the target image corresponding to the image acquisition region and the target image data volume corresponding to the target image, and determines the image data processing standard based on the final data form.

[0045] In some embodiments, the image data processing standard includes a plurality of sub-image data processing standards, and each sub-image data processing standard corresponds to a single data processing step. Therefore, when processing the target image corresponding to the target image data volume based on the image data processing standard, the target resource consumption corresponding to the single data processing step corresponding to each sub-image data processing standard can be determined.

[0046] In some embodiments, the image data processing standard includes a plurality of sub-image data processing standards, and each sub-image data processing standard corresponds to a single data processing step. Therefore, when processing the target image corresponding to the target image data volume based on the image data processing standard, the target resource consumption corresponding to the single data processing step corresponding to each sub-image data processing standard can be determined.

[0047] S103, generating a plurality of data processing logics based on the image data processing standard.

[0048] In some embodiments, during the process of processing the target image based on the image data processing standard, the processing based on the related program set in advance is required. Therefore, before processing the target image by the satellite, the processing program corresponding to the image data processing standard, i.e., the data processing logic, needs to be generated. The data processing resource of a single satellite cannot meet the data processing of the target image. The data processing logic needs to be installed in the target satellite in advance and needs to occupy a certain data processing resource of the target satellite. Therefore, a plurality of data processing logics can be generated based on the image data standard, wherein each sub-image data standard corresponding to the image data processing standard can be determined based on the analysis of the image data processing standard, and the data processing logic corresponding to the processing step can be generated based on the processing step. The plurality of data processing logics, the plurality of target satellites, and the plurality of sub-image data standards in the image data processing standard have a one-to-one correspondence.

[0049] S104, determining the target satellite corresponding to each data processing logic based on the plurality of target resource consumptions, sending the plurality of data processing logics to the target satellites corresponding to the data processing logics respectively, and sending the target image received by the initial satellite to the plurality of target satellites for processing based on the front and rear processing logics.

[0050] In some embodiments, after generating the plurality of data processing logics, the electronic device obtains initial data receiving and forwarding tasks corresponding to the plurality of initial satellites, wherein the initial data receiving and forwarding tasks are initial communication tasks of the initial satellites; then, the electronic device determines an initial remaining resource amount corresponding to each initial satellite based on the initial data receiving and forwarding tasks, and selects a target satellite corresponding to each data processing logic from the plurality of initial satellites based on the initial remaining resource amount and the data processing logics, and sends the plurality of data processing logics to the target satellites corresponding thereto for installation.

[0051] Then, the electronic device sends the target images collected by the initial satellites to the plurality of target satellites in sequence based on the order between the plurality of data processing logics, so that the target satellites process the target images, and after the initial satellites obtain the target images, the target images can be sent to the target satellites in sequence based on the order between the processing logics without splitting the target images, thereby improving the ability and efficiency of the target satellites in data processing.

[0052] In step S101, based on the communication task, the image data processing standard and the target image data amount corresponding to the preset unit time period are determined, including: based on the communication task, the image acquisition area of the initial satellite and the area information corresponding to the image acquisition area are determined; based on the area information and the communication task, the target monitoring area is determined from the image acquisition area; the reference image corresponding to the target monitoring area and the target image data amount corresponding to the reference image are obtained.

[0053] In some embodiments, the image acquisition area is an area that needs to be imaged by the initial satellite; the area information represents information of features such as buildings, vegetation, and roads contained in the image acquisition area; and the target monitoring area is a monitoring area with the largest range and most feature information that can be acquired by the image acquisition device of the initial satellite.

[0054] The electronic device generates an image acquisition instruction and sends it to the initial satellite. The initial satellite acquires the reference image corresponding to the target monitoring area in response to the image acquisition instruction. The initial satellite sends the reference image to the electronic device, and the electronic device determines the quantity corresponding to the reference image.

[0055] In step S102, based on the communication task, the image data processing standard and the target image data amount are determined, including: based on the communication task, the final data form corresponding to the target image acquired by the initial satellite is determined; the initial data acquisition type corresponding to the initial satellite is obtained; based on the final data form and the initial data acquisition type, a plurality of data processing steps corresponding to the initial satellite are determined; and the image data processing standard is determined from the plurality of data processing steps.

[0056] In some embodiments, the final data form is a data form of the to-be-sent image obtained after processing of the target image data collected by the initial satellite, and the initial data collection type is an image type of an image collected by an image collection means used by the initial satellite for image collection of the target monitoring area based on the communication task, such as a remote sensing image collected by the initial satellite using a remote sensing technology means.

[0057] The electronic device analyzes the communication task, determines the final data form of the final image obtained by the initial satellite, and obtains the initial data collection type corresponding to the initial satellite. The electronic device determines the collection end data form corresponding to the initial satellite based on the initial data collection type, and then determines a plurality of processing steps required for conversion between the collection end data form and the final data form based on the final data form and the collection end data form corresponding to the initial data collection type, and determines the plurality of processing steps as a plurality of data processing steps corresponding to the initial satellite. Then, the electronic device integrates the plurality of data processing steps to obtain the image data standard.

[0058] In some embodiments, the image data processing standard includes a plurality of sub-image data processing standards, and then in step S102, based on the target image data amount and the image data processing standard, a plurality of target resource consumptions are determined, including: determining the processing steps included in each of the plurality of sub-image data processing standards; based on the processing steps and the target image data amount, determining a sub-target image data amount corresponding to each of the sub-image data processing standards, wherein the sub-target image data amount is the data amount output after processing the target image based on the corresponding processing steps; and based on the sub-target image data amount and the sub-image data processing standard corresponding to the sub-target image data amount, determining a target resource consumption corresponding to each of the sub-image data processing standards.

[0059] In some embodiments, the electronic device determines the processing steps corresponding to each of the sub-image data standards, and then takes the target image data amount as the initial data amount, and simulates the image data amount output after processing by each processing step through a data processing simulation means, and determines the image data amount as the sub-target image data amount corresponding to the processing step. Then, the electronic device calculates the resource consumption required in the execution process of the processing step corresponding to each of the sub-image data standards based on the sub-target image data amount and the sub-image data standard corresponding to the sub-target image data amount, and determines the resource consumption as the target resource consumption.

[0060] In some embodiments, the plurality of target resource consumptions and the plurality of data processing logics have a corresponding relationship, and then, in step S104, determining the target satellites corresponding to the plurality of data processing logics respectively includes: obtaining initial data receiving and forwarding tasks corresponding to the plurality of candidate satellites, and determining initial resource consumptions corresponding to the plurality of candidate satellites respectively based on the initial data receiving and forwarding tasks; determining initial residual resource amounts corresponding to the plurality of candidate satellites respectively based on the initial resource consumptions; calling resource occupancies corresponding to the plurality of data processing logics respectively; and determining the target satellites corresponding to the plurality of data processing logics respectively from the plurality of candidate satellites based on the initial residual resource amounts, the resource occupancies, and the plurality of data processing resource consumptions.

[0061] In some embodiments, the initial data receiving and forwarding task is a data receiving and forwarding task currently being executed by an initial satellite, and the initial resource consumption is a resource amount consumed by the initial satellite when executing the initial data receiving task.

[0062] The electronic device generates a task acquisition instruction and sends the task acquisition instruction to the plurality of candidate satellites. The candidate satellites send the initial data receiving and forwarding tasks to the electronic device in response to the task acquisition instruction. The electronic device determines the initial resource consumptions corresponding to each of the candidate satellites based on analysis of the initial data receiving and forwarding tasks, and obtains total resource amounts corresponding to each of the candidate satellites. The electronic device subtracts the initial resource consumptions from the total resource amounts to obtain initial residual resource amounts corresponding to the candidate satellites.

[0063] The electronic device calls the resource occupancies corresponding to each of the data processing logics respectively, and determines the relationship among the initial residual resource amounts, the resource occupancies, and the plurality of data processing resource consumptions. The electronic device determines the target satellites corresponding to each of the data processing logics from the plurality of candidate satellites based on the relationship among them.

[0064] In some embodiments, determining the target satellites corresponding to the plurality of data processing logics respectively from the plurality of initial satellites based on the initial residual resource amounts, the resource occupancies, and the plurality of data processing resource consumptions includes: performing cumulative calculation on the resource occupancies and the target resource consumptions having the corresponding relationship to obtain a plurality of total resource consumptions; calling a preset quantity ratio and determining a plurality of target residual resource amounts based on the preset quantity ratio and the plurality of initial residual resource amounts; comparing the plurality of total resource consumptions with the plurality of target residual resource amounts respectively; and in the case that any of the plurality of total resource consumptions is not less than any of the plurality of target residual resource amounts, determining the satellite corresponding to any of the target residual resource amounts as the target satellite of the sub-data processing logic corresponding to any of the total resource consumptions.

[0065] In some embodiments, the electronic device accumulates the resource occupation amount and the target resource consumption amount corresponding to the relationship, determines the total resource amount of the selected satellite occupied when processing the target image of the initial satellite, multiplies the preset number ratio with the plurality of initial remaining resource amounts respectively to obtain a plurality of target resource consumption amounts, and then compares the plurality of total resource consumption amounts with the plurality of target resource consumption amounts. If any total resource consumption amount in the plurality of total resource consumption amounts is not greater than any target remaining resource amount in the plurality of target remaining resource amounts, it indicates that the satellite corresponding to the any target remaining resource amount meets the requirement of loading the data processing logic corresponding to the any total resource consumption amount and has the ability to process the target image based on the data processing logic. Therefore, the electronic device determines the satellite as the target satellite of the any total resource consumption amount corresponding to the sub-data processing logic, and sends the plurality of sub-data processing logics to the target satellites corresponding thereto respectively until the electronic device determines the target satellites corresponding to the plurality of sub-data processing logics.

[0066] In some embodiments, after the target image collected by the initial satellite is sent to the plurality of target satellites for processing based on the processing logic in step S104, the data processing method based on multiple satellites further comprises: obtaining a target remaining resource amount ratio corresponding to each of the plurality of target satellites; in a case where the target remaining resource amount ratio corresponding to any target satellite in the plurality of target satellites is less than a preset resource amount ratio, obtaining a target processing logic corresponding to the any target satellite and sending the target processing logic to the target candidate satellite; in a case where the difference between the first target data amount corresponding to the next target image adjacent to the target image and the second target data amount corresponding to the target image is greater than a preset difference value, and the next target image needs to be executed by the target processing logic corresponding to the any target satellite, the next target image is sent to the target candidate satellite.

[0067] In some embodiments, the target remaining resource amount ratio is the ratio of the remaining data resource amount of the target satellite to the total data resource amount in the process of processing the target image based on the processing logic corresponding thereto. The electronic device monitors the target remaining resource amount ratio of the plurality of target satellites in real time when processing the target image based on the processing logic corresponding thereto, and compares the target remaining resource amount ratio with the preset remaining resource amount ratio.

[0068] In a case where the target remaining resource amount ratio of any target satellite is less than the preset resource amount ratio, it indicates that the remaining data resource amount of the any target satellite is small when processing the target image based on the processing logic corresponding thereto. In the presence of an urgent temporary communication task, the any target satellite cannot meet the demand of executing the urgent temporary task.

[0069] Therefore, it can be considered to set an alternative satellite corresponding to any target satellite, that is, the electronic device obtains target processing logic corresponding to any target satellite, and sends the target processing logic to the determined target alternative satellite. Subsequently, in the case that the difference between the first target data amount corresponding to the next target image adjacent to the target image and the second target data amount corresponding to the target image is greater than the preset difference value, the next target image can be considered to be sent to the target alternative satellite for processing. After that, when the next target image needs to be executed by the target processing logic corresponding to any target satellite, the next target image is sent to the target alternative satellite for processing.

[0070] In some embodiments, after step S103, generating a plurality of data processing logics based on the image data processing standard, a multi-satellite-based data processing method further includes: obtaining a collection frequency of image collection on the centralized monitoring area corresponding to the initial satellite and an operation period of the initial satellite; in the case that the collection frequency is less than the operation period, determining a plurality of image collection satellites based on the collection frequency, and generating an auxiliary collection instruction; sending the auxiliary collection instruction to the plurality of image collection satellites to control the plurality of image collection satellites to collect images of the centralized monitoring area, thereby meeting the demand for image collection of the centralized monitoring area.

[0071] In some embodiments, after controlling the plurality of image collection satellites to collect images of the centralized monitoring area, it further includes: determining a data processing period corresponding to each of the plurality of data processing logics, and in the case that the maximum data processing period among the plurality of data processing periods is greater than the collection frequency, determining a first target satellite and a second target satellite corresponding to each of the plurality of data processing logics; the target images collected by the plurality of image collection satellites are odd-even encoded, and the odd-encoding target images are sequentially sent to the plurality of first target satellites for processing based on the front and rear data processing logics, and the even-encoding target images are sequentially sent to the plurality of second target satellites for processing based on the front and rear data processing logics, thereby reducing the occurrence of congestion in the process of processing the target images in the single-chain data processing mode due to the high collection frequency.

[0072] The present application provides a multi-satellite-based data processing device, which adopts the following technical solutions:
