Description

Technical Field

[0001] It involves the field of satellite mission planning. Background Technology

[0002] The mission planning system is a crucial component of remote sensing satellite ground operations and maintenance services. Its main function is to uniformly analyze and plan user demands from diverse sources, optimize satellite resource allocation, resolve resource conflicts, and improve satellite utilization efficiency. Currently, the demand for high temporal and spatial resolution remote sensing satellite imagery is increasing daily in various fields such as natural resource surveys, environmental protection, agriculture, forestry, power, transportation, water conservancy, and finance. Satellites need to maximize their imaging capabilities, acquiring as much data as possible while ensuring satellite safety. Simultaneously, to ensure a high success rate of data acquisition during actual use, some data needs to be retained. Therefore, how to store increasingly more data within limited storage space has become a pressing issue in mission planning.

[0003] In existing technologies, there is a study titled "A Remote Sensing Satellite Mission Planning Method Based on Genetic Algorithm," which proposes a remote sensing satellite mission planning method based on a genetic algorithm. This method optimizes satellite resource scheduling, resolves resource conflicts, and improves satellite utilization efficiency. The method uses a genetic algorithm to optimize the mission to achieve the optimal mission planning result. However, this research has shortcomings: it does not consider storage space limitations and data retention issues, thus failing to solve data storage problems; and it does not consider mission compression and data transmission processes, thus failing to achieve real-time release of storage space.

[0004] Another study, "A Remote Sensing Satellite Data Storage Method Based on File Number Allocation," presents a method for storing remote sensing satellite data based on file number allocation. This method assigns file numbers to data and sets the usage status and overwrite time of these file numbers to achieve data storage and release. This method shares a similar technical principle with the proposed solution, both addressing data storage through file number allocation and status management. However, this research has several drawbacks: it does not consider mission compression and data transmission processes, making it unable to achieve immediate release of storage space; and it does not consider mission priority and retention requirements, thus failing to retain data on demand.

[0088] Implementation Method Eleven, in conjunction with Appendix Figure 1-4 This embodiment describes the technical solution provided above in detail and completely, and demonstrates its beneficial effects through specific examples. Specifically:

[0089] Given a defined mission plan and the specific imaging, compression, and data transmission tasks, the storage allocation for imaging and compressed data needs to be completed. To address this storage issue, this implementation proposes a method for allocating file numbers for remote sensing satellite imaging and compression tasks. File numbers are assigned different usage states: unused, used and overwriteable, and used and incoverable. When allocating file numbers for imaging and compression tasks, used and overwriteable file numbers are prioritized, followed by unused file numbers. For data that does not need to be retained, the file number can be overwritten after compression or data transmission to achieve immediate storage release. For data that needs to be retained, the file number is set to incoverable, and can automatically switch to overwriteable after successful data production or after a period of retention to ensure data preservation. This method effectively solves the data storage problem.

[0090] Statistics from daily operational applications show that the results obtained using the file number allocation method for remote sensing satellite imaging and compression tasks are relatively accurate and reasonable, and basically meet the requirements of operational applications.

[0091] Specifically:

[0092] Step 1: Initialize the data transmission task set W, the imaging task set I, the compression task set P, the on-board storage imaging task file number set A, the set of used and overwhelmable file numbers in set A B, the set of used and non-overwhelmable file numbers in set A C, the set of unused file numbers in set A D, the on-board storage compression task file number set E, the set of used and overwhelmable file numbers in set E F, the set of used and non-overwhelmable file numbers in set E G, and the set of unused file numbers in set E H.

[0093] Step 2: Sort the imaging tasks in set I and the compression tasks in set P according to their start time. The sorted imaging task set is I. w The set of compression tasks is P w .

[0094] Step 3, for set I w Imaging tasks and ensemble P in w The compression task is assigned a file number, and the assigned imaging task file number is recorded in set M, while the assigned compression task file number is recorded in set N.

[0095] Step 4, Loop I w For each imaging task, assign a file number to each imaging task and set the overwrite time for the file number.

[0096] Step 4.1, Imaging Task I wi Determine I wiIs it a retransmission? If yes, do not assign a file number; otherwise, proceed to step 4.2.

[0097] Step 4.2, Imaging Task I wi Start time T i Calculate T i Given the file number status in time set A, and set D, update sets B and C. The current imaging time of the used file number x is T. ix File number x can be covered for a time period of T. x Maximum retention time t for the task i The calculation formula is:

[0098] T x =0&T i -T ix >=t i , x∈B

[0099] T x =0&T i -T ix <t i , x∈C

[0100] T x ≠0&T x <T i , x∈B

[0101] T x ≠0&T x >T i , x∈C

[0102] Step 4.3, Imaging Task I wi File number y is assigned, and the assignment rule is as follows:

[0103] y = min B

[0104] y = min D

[0105] Record the file number y in set M. If file number y is selected from set D, then remove y from set D.

[0106] Step 4.4, set the file number y to the overwrite time T. y ,

[0107] 1.I wi For tasks that cannot be overridden,

[0108] T y =0

[0109] 2.I wi This is a routine task that requires compression, which must be completed in one go. The compression completion time is T.p ,

[0110] T y =T p

[0111] 3.I wi This is a routine task that requires compression, and multiple compressions are needed. The end time of the final compression is T. pl ,

[0112] T y =T pl

[0113] 4.I wi For routine tasks, no compression is required and data transmission is completed in one go; data transmission completion time T. w ,

[0114] T y =T w

[0115] 5.I wi This is a routine task that does not require compression and involves multiple data transfers. The end time of the last data transfer is T. wl ,

[0116] T y =T wl

[0117] Step 4.5, determine set I w If all imaging tasks have completed their loop, proceed to step 5; otherwise, proceed to step 4.

[0118] Step 5, loop P w For each compression task, assign a file number to each compression task and set the overwrite time for the file number.

[0119] Step 5.1, Compression task P wi Start time T j Calculate T j Given the file number status in time set E, set H, update sets F and G, and the current compression time of used file number a is T. ja File number a can be covered for time T. a Maximum retention time t for the task p The calculation formula is:

[0120] T a =0&T j -T ja >=t p , x∈F

[0121] T a =0&T j-T ja <t p x∈6

[0122] T a ≠0&T a <T j , a∈F

[0123] T a ≠0&T a >T j , a∈G

[0124] Step 5.2, Compression Task I wi File number b is assigned, and the assignment rule is as follows:

[0125] b = min F

[0126] b = min H

[0127] Record file number b in set N. If file number b is selected from set H, then remove b from set H.

[0128] Step 5.3, set the overwrite time T for file number b. b ,

[0129] 1.P wi For tasks that cannot be overridden,

[0130] T b =0

[0131] 2.P wi For a routine task, data transmission is completed in one go, with a transmission completion time T. w ,

[0132] T b =T w

[0133] 3.P wi This is a routine task that requires multiple data transfers. The final data transfer ends at time T. wl ,

[0134] T b =T wl

[0135] Step 5.4, determine set P w If all compression tasks have completed their loop, proceed to step 6; otherwise, proceed to step 5.

[0136] Step 6: The successful production time of the downloaded data is T. s Set the overwrite time to T for the corresponding imaging file number. sDetermine if this task involves compression; if so, set the overwrite time to T for the corresponding compressed file number. s If not, end.

[0137] The following examples demonstrate the method of this implementation.

[0151] Currently, the task production status has been updated. Task 2 was successfully produced at 3.2 5:40:31. The overwriteable time for the corresponding original file number 2 and compressed file number 3 is set to 3.2 5:40:31. After the file number status is updated, file numbers are allocated to the imaging and compression tasks for the next day according to the method of this embodiment, and overwriteable times are set for the used file numbers.

[0158] Using this method, data that does not need to be retained can be overwritten instantly, releasing storage space immediately. Simultaneously, it allows for the on-demand retention of tasks that cannot be overwritten, with immediate overwriting when no longer needed. This method solves the storage problem in the planning process, significantly improving space utilization. This method effectively meets the needs of daily business applications; without it, mission planning would be more difficult, and satellite benefits would be diminished.
