Description

Spacecraft uplink control data generation method and device

Technical Field

The invention relates to the technical field of spacecrafts, in particular to a method and a device for generating uplink control data of a spacecraft.

Background

With the development of aerospace tasks, the types of spacecrafts are more and more, and the carried load is more and more complex. The ground control center carries out complex control on the spacecraft by means of uplink control data, the structure of the uplink control data tends to be diversified and irregular, and the application process is more flexible. The data structure is defined by a software hard coding mode conventionally, and the generation and framing of uplink control data are carried out, so that the uplink control data are required to be realized by separate programming aiming at different spacecrafts and loads. This approach requires high and enormous effort on the software development and maintenance team. And the part of ground control center adopts a database parameter binding mode to carry out fixed description definition on each control data structure, and uplink control software reads the database binding parameters to carry out framing to generate data, and the structural change of the uplink control data is adapted by manually adjusting the binding parameters. The method can support spacecraft control tasks with small number of data structures and small change, and when the types of the spacecraft are more, the difference of control data structures is large, and the number of the data structures reaches tens of thousands, the workload of manual binding maintenance is huge.

Specifically, in the spacecraft control process, the spacecraft is single in type and simple in control data structure. The data structure is usually defined by a software coding mode, and each type of control data structure is realized by adopting a set of complete codes to generate and frame the uplink control data. After the user inputs the control parameters to be transmitted and the software reads the parameters, the source code conversion and the assembly are carried out according to the data structure type defined by the codes, and a control data file in a binary format or a text format is generated. When the control parameters change, the software code is modified again, and the processing and the generation of a new uplink data structure are realized. The scheme is only suitable for the conditions that the control data structure is simple and few in variety, and for the complex control data structure, the program code amount is huge, and the workload of software development and programming maintenance is great. Because the control data structure description is carried out by adopting a software coding mode, when the control data structure is changed, the software code needs to be changed, and the version control and the reliability of the software are greatly reduced. When the types of the spacecraft are increased, a large number of repeated codes exist in the software, and the maintenance of the software is very heavy.

In addition, part of ground control center adopts database parameter binding mode to describe control data structure, each control data structure is defined as a structural parameter in database, and uplink control software reads database binding parameter to complete loading of control data structure and type. After the software reads the parameters, the source code conversion and the assembly are carried out according to the data structure type bound by the database, and a control data file in a binary format or a text format is generated. When the structure of the control parameter changes, the binding parameter is adjusted manually to adapt to the structural change of the uplink control data, and the software code does not need to be modified any more. The method can support spacecraft control tasks with small number of data structures and small change, and when the types of the spacecraft are more, the difference of control data structures is large, and the number of the data structures reaches tens of thousands, the workload of manual binding maintenance is huge. According to the scheme, each type of control data structure is completely unfolded and bound, and the scheme is visual. However, the top layer structure and the middle layer structure of various control data of the same spacecraft are the same, and the scheme does not fully utilize the characteristic, so that the data structures are classified and integrated, the workload of binding is great, and the storage resources of the database are wasted.

In this embodiment, a control data structure extraction, framing, and generation processing architecture is designed. As shown in fig. 6, this architecture is composed of a frame structure extraction binding unit, an instruction structure tree creation unit, and a data step-by-step framing generation unit.

In a specific embodiment of the present invention, this embodiment describes a process of extracting an uplink control data structure of a spacecraft, describes a process of dynamically assembling an identification word and constructing an instruction structure tree, and describes a data generation method of an inner layer frame and an outer layer package in combination with control parameters input by a user.

Providing a frame structure FILE1 by an external system, wherein the content is shown in fig. 2; the expansion instructions defined by the user design are SHELL1 to SHELL5, the basic instructions are CMD1 to CMD5, and the content is shown in FIG. 8; the control parameter FILE input by the user is FILE2, and the content is:

command code string shell1+cmd1, parameters a=1, b=2, c=3;

command code string shell1+cmd2, parameters e=1, f=2;

command code string shell2+cmd1, parameters a=10, b=20, c=30;

command code string shell1+cmd4, parameters x=1.4, y=2.9, z=1.5.

Step one, frame structure information extraction and binding. The system extracts the information of the 'mapping between the identification word and the data unit', and an external user manually performs the instruction information of design and binding according to the extracted information of the 'mapping between the identification word and the data unit' and in combination with the control requirement of an external spacecraft development unit, and stores the information of the 'mapping between the identification word and the data unit' and the instruction information into a database. The frame structure information extraction and binding working steps of the invention are as follows:

(1) As shown in fig. 2, the identification word extraction module performs frame structure decomposition and extraction on the external frame structure FILE1 layer by layer. Firstly, processing the highest layer, and using 11H of a data frame A as an identification word for uniquely identifying the frame structure; the DATAFRAME field corresponds to the underlying data content as a data unit field, which has no specific format for pointing to the underlying structure; the "TAIL" field is the end of frame, which is a fixed value of "00H"; the frame structure to which the identification word "11H" points therefore includes: "11H", "DATAFRAME", "00H".

(2) Continuing to process the data frame B in the same way, extracting the identification word "12H" to point to the frame structure: "12H", "DATAFRAME", "TAIL"; after the highest layer processing of fig. 2 is completed, the repeated identification words are deleted, the frame structure corresponding to the identification words "11H" and "TAIL" is used as the 1 st layer and named as "TOP", and the extraction of the highest layer identification word and data unit mapping information is completed.

(3) Continuing with the second layer of fig. 2, the identification words "21H", "22H", "23H", and corresponding frame structures are extracted in the same way; the second layer is named the name "DATAFRAME" of the data unit of the upper layer (first layer); and the extraction of the second layer of information of the identification word and the data unit mapping is completed.

(4) When processing the third layer, 5 recognition words can be extracted: "31H", "32H", "33H", deleting duplicate identifiers "32H" and "33H", and the final extracted list of identifiers is "31H", "32H", "33H", and frame structure; the processing of the lower layers of fig. 2 continues until the last layer of the frame structure, i.e. the last layer has no data unit fields, is extracted. The "identifier-data unit mapping" information shown in fig. 7 is constructed and stored in the system database.

(5) Binding instruction information such as basic instructions and expansion instructions to a database. The binding of the basic instruction and the expansion instruction is designed manually according to the external requirement, and no fixed program or method is adopted, and the binding is not taken as the content of the invention. The purpose of this process is to design two types of instructions, representing the basic function control instructions and the shell of the basic instructions, respectively. The two types of instructions are added with basic identification words and extended identification words, and the basic identification words and the extended identification words are used for representing frame structures corresponding to the instructions. As shown in fig. 8, the identification words of the command CMD1 are "31H, 41H", and indicate framing using the frame structure corresponding to the "31H" identification word of the 3 rd layer and the frame structure corresponding to the "41H" identification word of the 4 th layer. The extensible nature of a base instruction represents the shell that the instruction can use. As shown in fig. 8, the extensible attribute of the command CMD3 is "SHELL1, SHELL3, SHELL4", which means that the command can be packaged with the extended commands SHELL1, SHELL3, SHELL4, but cannot be packaged with the commands "SHELL2, SHELL 5".

Step two, identifying the dynamic assembly of words and constructing an instruction structure tree. And loading frame structure information from a database by a binding information loading module, traversing and expanding the frame structure information by an instruction tree creation module, constructing instruction structure tree information, and storing the instruction structure tree information into a system cache. The working steps are as follows:

(1) By establishing a link between the basic instruction and the extended instruction, dynamic combination association of the extended identification word of the extended instruction and the basic identification word of the basic instruction is realized. As shown in fig. 8, the basic instruction and the extended instruction list are read; traversing the extended instruction list.

(2) And acquiring a 1 st expansion instruction SHELL1, traversing all basic instructions CMD1 to CMD5 according to the SHELL1 instruction code, and checking whether the expandable attribute of the basic instruction CMD1 contains the instruction code SHELL1. If the extensible attribute of the command CMD1 contains SHELL1, adding the CMD1 into a child node linked LIST LIST1 of SHELL 1; otherwise, not processing the command CMD1; the next command CMD2 is continuously read. When the command SHELL1 completes the processing of the basic command CMD5, the child node LIST1 of SHELL1 contains 5 basic commands "CMD1 to CMD5".

(3) And establishing an instruction structure tree corresponding to the instruction SHELL1. Taking an instruction code number SHELL1 of the extended instruction as a root node of the tree structure; reading the information of the identification word-data unit mapping shown in fig. 7, traversing the extended identification words 11H, 21H of the extended instruction SHELL 1; the frame structure corresponding to the 1 st identification word "11H" is acquired from the 1 st layer of fig. 7, the identification word field "11H" is added below the root node as a child node, the frame structure "DATAFRAME" field is linked to the "11H" node in turn, and the "TAIL" field is linked to the "DATAFRAME" node.

(4) Continuing to acquire a frame structure corresponding to the 2 nd identification word 21H from the 2 nd layer, and linking the identification word field 21H to the data unit field DATAFRAME corresponding to the 1 st identification word 11H as a child node; the SYS field of the frame structure is sequentially linked to the 21H node, and the traversing of the extended identification word of the command SHELL1 is completed.

(5) Traversing the basic commands CMD1 to CMD5 in the child node linked LIST LIST1 of the SHELL1 in turn, and adding the commands CMD1 to CMD5 to the data unit SYS node of the last identification word 12H of the expansion command SHELL1 in turn as child nodes. The links of the base commands CMD1 to CMD5 to the upper level "SYS" node are dynamic (identified by the dashed lines in fig. 9).

(6) Processing basic commands CMD1 to CMD5 one by one, traversing basic identification words 31H and 41H of the basic command CMD1, sequentially adding frame structure fields corresponding to the identification words 31H and 41H, wherein the adding method is the same as that of an expanding command, and linking to the bottommost node: a, B, C parameter information for BLK 1. After the processing of the basic command CMD1 is completed, the processing of CMD2 to CMD5 is continued.

(7) After traversing the child node linked LIST1 of the SHELL1 is completed, the construction of the instruction structure TREE1 corresponding to the instruction SHELL1 is completed, and the system stores the TREE1 into a cache. Fig. 9 shows an instruction structure TREE1 of the extended instruction SHELL 1. The system continues to construct the instruction structure TREEs TREE2 to TREE5 of the extended instructions SHELL2 to SHELL5 according to the steps of (2) to (6), and sequentially stores the instruction structure TREEs TREE2 to TREE5 into a system cache for the instruction framing call.

Thirdly, after a user inputs a control parameter FILE2, a corresponding instruction structure tree is instantiated according to an instruction list to be framed and related data in control parameters, and framing of data blocks is carried out in a step-by-step generation mode of inner layer framing and outer layer packaging, so that complete control data source codes are generated. The working steps are as follows:

(1) The control parameters instruct the grouping. The system reads the control parameter FILE2, sorts and GROUPs the control parameter FILE2 according to the instruction code strings, GROUPs the instruction code strings with the same expansion instruction into the same GROUP, and GROUPs the control parameter FILE2 into 2 GROUPs, GROUP1: shell1+cmd1, shell1+cmd2, shell1+cmd4; GROUP2: SHEL2+CMD1. Next, GROUP1 and GROUP2 are sequentially processed, instruction framing and data generation processing are performed, and GROUP1 is first processed.

(2) An instruction structure tree is instantiated. Loading an instruction structure TREE1 corresponding to an expansion instruction SHELL1 of the GROUP1, searching basic instructions CMD1, CMD2 and CMD4 in the GROUP1 in the instruction structure TREE1, determining links from the basic instructions CMD1, CMD2 and CMD4 to a superior node SYS, deleting links and child nodes of the instructions CMD3 and CMD5 in the TREE1, and completing the instantiation of the instruction structure TREE, wherein FIG. 10 is an instruction structure TREE GROUP1_TREE1 instantiated according to the GROUP1.

(3) The inner layer of the basic instruction frames. Traversing child nodes of the instructions CMD1, CMD2 and CMD4 in the instantiated GROUP1_TREE1, and performing parameter processing and framing from top to bottom. The 1 st identification word "31H" and the frame structure field "DAT" of CMD1 are assembled in sequence, first 31H is converted into source code, and then field "DAT" is processed, because field "DAT" is a data unit field, and framing of the frame structure of "31H" is suspended.

(4) According to the identification word 41H linked by the data unit field DAT, framing the identification word 41H and the frame structure, including converting the parameters A=1, B=2 and C=3 into corresponding data block source CODEs 41; when the bottom layer "41H" of the command CMD1 identifies that the frame structure is assembled, the composed data block "CODE41" is returned to the "31H" layer as the content of the data unit field "DAT" of the "31H".

(5) Continuing the frame structure processing of 31H, framing to generate a data block source CODE CODE31, and sequentially returning to the upper layer until the 1 st layer of the command CMD1 to generate the whole data block source CODE CODECMD1 corresponding to the command CMD 1.

(6) Continuing to process commands "CMD2 and CMD4" in GROUP1_TREE1, and generating data block source codes "CODECMD2" and "CODECMD4". The source code lengths of the generated data blocks "codec cmd1", "codec cmd2", and "codec cmd4" are 65B, 31B, 55B, respectively.

(7) After the basic instruction generates the data blocks, the data block lists "codec cmd1", "codec cmd2", and "codec cmd4" are returned to the expansion instruction SHELL1 as the input contents of the bottom-most identification word "21H" data unit "SYS".

(8) The outer encapsulation of the instruction is expanded. And traversing the child node of the command SHELL1 in the GROUP1_TREE1, performing parameter processing and framing from top to bottom, wherein the framing method of each layer is the same as that of the basic command except the bottommost layer. When framing the "SYS" field of the frame structure of the lowest identification word "21H", the data blocks "CODECMD1", "CODECMD2" and "CODECMD4" are added in sequence to the "SYS" field.

(9) First, a data block "codec 1" is added, and before the data block is added, it is determined whether the total length of the added data block exceeds the maximum length attribute max=100deg.B of the instruction SHELL 1. The length of the data block of the CODECMD1 is 65B, and is smaller than the maximum length, the data block CODECMD1 is added; continuing to add the data block CODECMD2 (length 31B), and adding the data block CODECMD2 if the total added length 65B+31B=96B is smaller than the maximum length; continuing to add the data block codec 4 (length 55B), and if the total length added 96b+55b=151B is greater than the maximum length 100B, suspending the addition; copying the SHELlnew1 instruction structure tree as SHELlnew1, and linking the non-added data block 'CODECMD 4' under the SHELlnew1 instruction structure tree; continuing to complete the data encapsulation of the SHELL1 instruction, a final data block FRAME1 is generated.

(10) And continuing to process the instruction structure tree SHELnew 1 according to the same method, and completing encapsulation framing of the instruction SHELnew 1 to generate control source code data FRAME2.

(11) Continuing to process the GROUP2, and referring to the steps (2) to (10), carrying out the instantiation of the instruction structure tree, the inner layer framing of the basic instruction and the outer layer encapsulation of the extended instruction to generate the final control data source code FRAME3.
