B determines the data frame injected not successfully according to the effective number；
C decompose again to the data frame injected not successfully and be refilled；
The data frame of d mono- injection file is all after the completion of injection, and ground control station is by the file size of the injection file
It is sent to spaceborne image processing apparatus, spaceborne image processing apparatus receives the file size of the injection file.
Below with reference to Fig. 4, to the spaceborne in-orbit configuration method of file provided in an embodiment of the present invention to parallel computation unit 1
In-orbit restructuring procedure is described in detail:
In-orbit restructuring procedure is divided into 3 stages:
First stage injects the decomposition of file, is completed by ground control station.
G1: injection frame decomposes: injection file is decomposed into multiple data frames.
Injection file is decomposed into the data frame for meeting certain byte length by ground control station, for the integrality for guaranteeing data
And correctness, the frame head part of each data frame include that injection reference number of a document, the file of injection file belonging to data frame are long
Effective frame number of degree and data frame, contains the CRC16 check code of 2 bytes in the trailer sections of data frame, naturally it is also possible to be
Other check codes, such as MD5 check code.
G2: data frame decomposes: each data frame is decomposed into some instructions frame.
For the safety for meeting satellite-ground link transmission, data frame is decomposed into the command frame of the word lengths such as several, each data
Frame decomposites the command frame come according to the byte sequencing of decomposition labeled as first frame, intermediate frame and tail frame.
G3: command frame is sent: for each data frame, the command frame of decomposition being sent out according to the sequencing of decomposition
It goes.
For each data frame, the command frame of decomposition is sent to star by satellite-ground link according to the sequencing of decomposition
Image processing apparatus is carried, is received by processing unit.
Second stage, file injection, is completed by spaceborne image processing apparatus.
S1: command frame receives: the instruction after the processing unit of spaceborne image processing apparatus receives command frame, to command frame
Coding is identified and is parsed, and is determined as injecting command frame and be received.
S2: command frame is assembled: carrying out assembly to received command frame and obtains data frame；
Based on the received the first frame of sequencing and command frame, intermediate frame and tail frame flag to command frame carry out it is assembled and
Framing forms complete data frame.
S3: data frame check: the check code for extracting the postamble position of data frame verifies data frame.
Identify and record the injection reference number of a document of the frame head part of data frame, the file size of injection file and data frame
Effective frame number is extracted the CRC16 check code of the trailer sections of data frame, is verified to entire data frame, and verification is correct
Data frame be written data buffer area, abandon the data frame of check errors.
S4: correct data frame write-in data storage device will data frame write-in: be verified.
Correct data frame will be verified, according to the injection reference number of a document of record and effective frame number, data storage is written
Respective file area, the data of memory block are written, in addition to inject data frame, also include CRC16 check code.
S5: (i.e. the secondary verification of data frame) is verified after data frame write-in: the data frame of write-in data storage device is carried out
Secondary verification.
The data frame of write-in is read, and one check code (verification after write-in is calculated using checking algorithm to the data frame
Code), the existing check code (check code before write-in) of the check code being calculated and the data frame is compared；It is write if consistent
Enter success, otherwise write-in failure.
Specifically, reading the data frame of write-in, and execute CRC16 verification to the data frame of reading and calculate after data frame writes
Method calculates verification, by the result of calculating and the CRC16 check code of write-in and is compared, and success is written if unanimously, otherwise
Write-in failure.If be written successfully, processing unit needs the effective number of the successful data frame of tracking telemetry and command station return write-in to the ground,
Write-in failure does not have to then return.The effective number for the data frame that ground is returned by statistical disposition unit, it may be determined which data
Frame is successfully injected into configuration unit, by the comparison with injection file, can be divided again the data frame injected not successfully
Solution, refills.
S6: injection File Integrity Checking: for the file size ratio of the data frame length and injection file that are successfully written
To judge whether injection file is complete.
Can determine whether injection file is complete with the data frame length for being successfully written into data storage by comparing file size
Whole, if file size is equal to the data frame length for being successfully written data storage area, then the injection file is complete, updates injection text
