The channel telemetry information may be stored in a formatted document, such as an eXtensible Markup Language (XML) formatted document or a lightweight data interchange (JavaScript Object Notification) document. The XML document and the JSON document are easy to read and write by people and easy to analyze and generate by machines. The embodiments of the present disclosure do not limit this.

In step S102, a ground decoding program source code writing decision tree is established, that is: the method is mainly characterized in that the source code of the ground decoding program is defined in a standardized manner, common points in the telemetry decoding process of different satellite channels are converted into the standardized definition, and artificial intelligent writing is facilitated.

And step S103, writing a satellite channel telemetering decoding program according to the channel telemetering information described in the formatting of S101 and the decision tree in the step S102.

In one embodiment, step S101 includes using a database to format the channel telemetry information. For example, according to the programming language of the written code, databases such as Access, Oracle, DB2, Sybase, MS SQL Server, information x, MySQL, etc. may be selected for use, for example, when the programming language is asp. Any one of the databases can describe the wave channel telemetry information in a formatted manner, that is, the corresponding content can be configured in a manner of updating a data table, for example, 1 day, 10 hours, and 60 minutes, and is uniformly updated into data divided into units: 1440 min, 600 min, 60 min.

Further, the database in the above embodiment includes a channel telemetry information definition data table, and step S101 is specifically implemented, as shown in fig. 2, that the channel telemetry information definition data table 2 completes telemetry state quantity definition 21 and channel allocation information definition 22, and the telemetry state quantity definition 21 completes state quantity intra-satellite transmission information definition 211 and telemetry coding and decoding mode definition 212; channel allocation information definition 22 completes telemetry primary channel allocation definition 221, channel content definition 222, telemetry operating conditions 223, and state quantity definition 224.

The channel allocation information defines that the configured telemetering state quantities sequentially form a working condition, a source packet, a channel combination and a channel according to the channel allocation requirement.

For example, satellite position vectors Rx, Ry, Rz and satellite attitude vectors θ x, θ y, θ z are downloaded through multiplexed channels.

Firstly, defining the state quantity downloaded from the satellite as follows:

TABLE 1 State quantity definition

The satellite position vector and the attitude vector are downloaded alternately through a wave channel, and the wave channel combination used is defined through a main wave channel distribution table, as shown in a table 2;

TABLE 2 Main channel definition

Serial number	Number of occupied channels	Initial wave channel	Termination channel	Name (R)
					1	1	1	2	Channel1

The channel allocation working condition definition table defines the working conditions contained in the channels, as shown in table 3;

Working condition number	Number of internal state quantity of working condition	State quantity attributes	Number of state quantity	Dimension of state quantity
					1	1	Single machine state quantity	1	3
2	1	Single machine state quantity	2	3

Through the combination, the configuration of the telemetry channel for telemetering and downloading the satellite position and attitude information is formatted and described and is used as the input of the subsequent artificial intelligence programmer for automatically writing the source code.

In this embodiment, for different satellites, the telemetry subsystem design has both a similar framework structure and different telemetry information definitions. A source code writing method of a digital satellite channel telemetering ground decoding program based on formatted description converts common points in different satellite channel telemetering decoding processes into standardized definitions and database description, and different points adopt database configuration information. And combining the two to realize the automatic writing of the source code of the decoding program. The method can greatly reduce the workload of the simulation development of the telemetry subsystem, reduce the error rate and improve the research and development efficiency.

A process for writing a satellite channel telemetering decoding program source code by an artificial intelligence programmer relates to an information acquisition module, a writing decision tree building module and an automatic writing module.

The information acquisition module reads the formatted description record of the telemetering channel telemetering information under the current working condition written by the artificial intelligence programmer, and the formatted description record comprises telemetering state quantity definition information and channel distribution definition information.

The intelligent decision module establishes a decision tree for automatic writing of a channel telemetry decoding program. And establishing a source code program set according to the source code of the existing satellite channel telemetry decoding program. The intelligent decision module clusters the source code assembly according to the universality of the codes. The result of the clustering divides the source code into a variable portion and an immutable portion. And further clustering the variable parts and the invariable parts according to functions to obtain functional files. Wherein, the immutable part mainly includes fixed code files such as data receiving and dispatching simulation, data processing, etc., namely: a data transceiving analog source file and a telemetry data decoding function source file; the variable part mainly comprises related files such as telemetry channel definition, parameter definition, channel allocation definition and the like, namely a telemetry channel definition head file, a telemetry parameter macro definition head file, a channel allocation working condition analysis source file, a channel working condition judgment source file and a channel working condition decoding source file. And establishing an intelligent writing decision tree according to the clustering division result, and determining the writing standard of each file.

And the automatic writing module converts the formatted description recording result of the satellite design result into a satellite channel telemetering ground decoding program source code according to the decision tree result. And in the writing process, a corresponding C language engineering file is created, and the required codes are written into the file, so that automatic writing is realized.

In one embodiment, step S102 establishes a ground decoding program source code writing decision tree, including: performing multi-level decomposition on a satellite telemetry channel decoding program source code; establishing a writing decision tree of a source code of a satellite telemetry channel decoding program; and establishing an artificial intelligence programmer for executing the standard writing operation according to the branch condition of the decision tree.

Further, the bottom decoding program source code is defined in a standardized manner, and can be further implemented as an invariable part and a variable part according to whether the decoding program source code changes with the database configuration information in the generation process. The invariable part mainly comprises fixed code files such as data transceiving simulation, data processing and the like, namely: a data transceiving analog source file and a telemetry data decoding function source file; the variable part mainly comprises related files such as telemetry channel definition, parameter definition, channel allocation definition and the like, namely a telemetry channel definition head file, a telemetry parameter macro definition head file, a channel allocation working condition analysis source file, a channel working condition judgment source file and a channel working condition decoding source file.

This is illustrated below simply by two examples.

For example, the general code file can be divided into five types of files, namely negotiation registration, communication data transceiving simulation, data reading and writing preprocessing, file reading and writing and processing and a mathematical function library according to function division. The five types of files are respectively stored in five folders of Agent, Data, File, IO and Maths and are stored as fixed C/C + + source files and header files. And adding the data into decoding program engineering in a direct copying mode.

The encoding and decoding mathematical function library file is used as an independent file, and processing functions corresponding to all encoding and decoding modes which can be supported by a decoding program are saved. The coding and decoding method comprises linear compression, remote measurement value and binary original code, binary complement code, binary offset code, eight-system original code, sixteen-system original code conversion, binary and temperature quantity conversion, binary and remote measurement voltage quantity conversion, linear interpolation and table look-up method.

And secondly, for example, the personalized code file can be divided into two parts, namely data transmission definition and wave channel analysis according to the functional division.

Parameters required by the program deployment process are defined in a header file mode, and the file is realized in a fixed template mode. When writing a file, firstly writing a fixed header file and a mode macro definition variable. Variables involved in the data transfer are then defined, such as by char array. The array contains content written according to the contents of the federal configuration related data sheet. And finally, defining the telemetry transmission channel in a macro definition mode.

The channel analysis part is divided into 3 files, and the functions of data packet decoding, channel decoding and working condition decoding are respectively realized. The writing format, the header file, the variable definition and call, the function definition and statement call content are specified in the file.

a. The writing format is standardized: the function defines the line wrapping after the curly brace. Variable declarations are one line empty from the concrete operation statement. The operator is empty before and after the operator. The same level of code alignment, different levels are indented in sequence. The two functions are spaced one grid apart.

b. Header file specification: the header files contained in the file comprise a system header file and a user defined header file, the content of the system header file is fixed, and the system header file and the user defined header file are directly written through code segments.

c. Variable declaration and invocation specification: and the name and the type of the telemetering state quantity are determined according to the name and the type of telemetering basic byte data and telemetering comprehensive byte data in the related data table, and the variable type identifier is added as a variable prefix during naming. The telemetry state quantity is defined as a static variable. The telemetry channel combination is defined as char array, the array length is the number of occupied channels, for example, the array name is defined as "chr + start channel number + end channel number".

d. Function definition and declaration call specification: the method comprises the steps of realizing the process from main channel analysis to channel combination by using an independent function, fixing the input and output of the function, and specifically dividing the specific contents into telemetering channel combination array definition, temporary state quantity definition, channel analysis to channel combination level and calling the next layer of analysis function, wherein the temporary state quantity definition is a fixed code segment, and the rest contents are written according to a telemetering main channel distribution table.

The working condition analytic function is divided into two layers, and the first layer is working condition judgment. For example, the function name is defined as 'Parse + channel combination name', and the function inputs the current receiving frame number and the telemetering channel combination array variable; and defining a temporary variable ucConditontoindex, assigning values to the variables according to the working condition judgment result, and calling a state quantity analysis function according to the variable assignment result. The second layer is a state quantity analysis function, for example, the name of a normalized function is defined as 'ParseChannel + initial channel number + termination channel number + case + working condition sequence number', and the function input frame number ucFrameIndex and the telemetering channel combined array variable. And the function solves the state quantity from the working condition array into the telemetering state quantity variable and calls a corresponding decoding function for decoding. For the state quantity which does not adopt the coding, directly copying the corresponding length content from the working condition array variable into the corresponding state quantity; for the state quantity adopting coding, firstly copying the content with corresponding length from the working condition array variable into a temporary variable, then calling a decoding function to decode the temporary variable represented by binary system into a physical quantity and storing the physical quantity into the corresponding state quantity.
