Based on this, referring to fig. 1, it shows a schematic diagram of a method for designing an intelligent management system of a digital satellite according to an embodiment of the present invention, where the method includes:

s101: respectively designing a satellite design research and development subsystem, a satellite production manufacturing subsystem, a satellite remote control and remote measurement subsystem and a satellite digital twin subsystem based on the full-flow service of the links from design, production manufacturing, test to on-orbit maintenance of the satellite;

s102: designing a resource database as a bottom support aiming at the full-flow service; wherein the resource database comprises: the system comprises a component model library, a component archive library, a whole star model library, a whole star archive library, a design resource library, a process resource library, a protocol resource library and a test resource library; and each database is independently decoupled and can interactively communicate.

In some examples, in connection with the structure of the resource database 10 designed by the above scheme shown in fig. 2, the designing the resource database as an underlying support for the full flow service includes:

a management component (not shown in the figure) is arranged for each database, and a management maintenance interface (shown as a point filling block of each database in fig. 2) is arranged to facilitate management updating and maintenance of internal data information of each database, so that independent maintenance of data information in each database can be realized; in addition, an information output interface (as shown in fig. 2, which is not a filling block of each database) is correspondingly provided for each database, and is used for providing the information, which is managed, updated and maintained inside the database, to other databases, so that the other databases synchronize the information, which is managed, updated and maintained by the database.

In some examples, corresponding identification information is set for each item of data information in each of the above resource databases so that the data information is uniquely identified and confirmed. In addition, corresponding version control content can be set for each item of data information in the database, and the version control content is transmitted to other databases through the information output interface, so that the other databases can confirm that the synchronized data information is up to date.

In addition to the above settings for all databases, in some examples, the designing a resource database as an underlying support for the full flow service includes, in a design process for a single database:

and correspondingly setting an attribute set consisting of a plurality of characteristic attribute values for each component model or the whole star model in the component model library or the whole star model library, wherein each attribute in the attribute set correspondingly describes one characteristic of the model. It should be noted that all data or information related to the model can be a part of the model, and the data or information has a relatively complex and various representation forms, and in order to be able to maximally contain the data and information related to the model and make it easy and convenient to digitize, the embodiment of the present invention sets that each model (component model or whole star model) has a plurality of attributes, and each attribute value corresponds to one of the characteristics that describe the model, and based on this, an attribute set formed by a plurality of attribute values can describe a specific model in detail and completely. In some examples, as shown in fig. 3, the attribute values may be represented in a single-value form or a list form, and each attribute corresponds to one representation form, such as a single value or a list, in combination with the attribute set formed by N attributes corresponding to the model (component model or whole star model) shown in fig. 3. For example, taking the single-value attribute values shown in attribute 1 and attribute N as an example, the value types thereof may be expressed as a single text, a numerical value, a boolean value, a list, a picture or a file, etc.; taking the list attribute value shown in attribute 2 as an example, it may be considered that the list attribute value is formed by combining a plurality of single values, for example, 3 single values (identified as value 11, value 21, and value 31) shown in attribute 2 in fig. 3, and the combination of these single values can describe the attribute of a certain characteristic of the model as a whole, and therefore, the value type in the list may include text, a numerical value, boolean, or a list.

And designing the component archive or the whole star archive to be mainly used for storing the archive information which is converted from the model and is suitable for purchase and production, so that the archive information in the component archive or the whole star archive corresponds to each component model or whole star model in the component model library or the whole star model library. In some examples, the archive information corresponding to each component model or whole star model in the component archive or whole star archive may be added with the content related to finance, supply chain and production and manufacturing, such as manufacturer information, price information, process information, etc., on the basis of the corresponding model information. In the representation form, i.e. the single value or the list, of the respective model information may preferably be inherited; the corresponding representation may also be adaptively generated, preferably in accordance with computer or process system software using the resource database 10.

For the design resource library, the design resource library is designed to be mainly used for integrating design resources, such as pictures, CAD documents, 3D model files and other information, used by the satellite in the component and whole satellite design stage, and the design resources can exist in the representation form of files. With the continuous design, production and manufacture of the satellite, the resources in the resource library can be continuously expanded to accelerate the design efficiency of the satellite components and the whole body.

The library of process resources is designed to include the various process requirements that are to be followed to process and test the various components during the manufacturing process. These process requirements may be stored in the form of representations of various process documents and process specification texts.

The protocol resource pool is designed to include various protocol information contained or employed by the satellite components, which exist in text form, and which are the basis for intra-satellite as well as inter-satellite communications.

The test resource library is designed to comprise all test cases and test methods of components or whole stars in the production and test stages. With the continuous design, production and manufacture of the satellite, the content of the test resource library can be continuously modified and enriched, the production efficiency of the satellite can be accelerated, and the overall reliability of the satellite can be improved.

In combination with the above configuration and design content for each database in the resource database 10, in some examples, the resource database designed as a bottom support for the full flow service may be specifically designed for the resource database 10, and the architecture may be used to represent information flow trend and interaction between the databases, as shown by solid arrows in fig. 4:

designing a protocol resource library to provide support of communication protocol information for each component model in a component model library; respectively designing a component model library and a whole star model library to provide a data basis for archive information of corresponding models of the component archive library and the whole star archive library; designing a design resource library to provide support for design resources related to the models in the component model library and the whole star model library; the process repository and the test repository are designed to support process information and test information related to the component archive and the whole star archive, respectively.

It should be noted that through the design process for the composition and architecture of the resource database 10 shown in fig. 2 to 4, the databases are not only independently decoupled, but also can be mutually associated and interactively communicated, so as to achieve communication between the digital satellite underlying libraries, thereby providing core support for the full-flow service of the satellite from design, production, manufacturing, testing, and even in-orbit maintenance links.

With reference to fig. 1 to 4, designing a satellite design and development subsystem, a satellite production and manufacturing subsystem, a satellite remote telemetry subsystem, and a satellite digital twin subsystem respectively for the full flow service from design to production and manufacturing to test to in-orbit maintenance link based on the satellite described in S101, which may be specifically implemented to design and obtain a digital satellite production and manufacturing system 50 as shown in fig. 5, where the digital satellite production and manufacturing system 50 includes: a satellite design development subsystem 501, a satellite production manufacturing subsystem 502, a satellite remote telemetry subsystem 503 and a satellite digital twin subsystem 504; wherein the content of the first and second substances,

the satellite design development subsystem 501, configured to: generating a target whole satellite model matched with the satellite to be produced from a model database and a file database of the whole satellite and the satellite components based on the overall design requirement of the satellite to be produced;

the satellite production manufacturing subsystem 502 configured to: acquiring corresponding component information, a whole satellite material list and process information from the satellite resource database according to the target whole satellite model, and disassembling the corresponding component information, the whole satellite material list and the process information into corresponding production tasks and corresponding materials which are issued to corresponding stations to perform corresponding production and assembly of each component of the target whole satellite model so as to obtain a target satellite finished product;

the satellite telemetry sub 503 is configured to: testing the target satellite finished product based on a protocol resource database and a test resource database to complete a test task before the whole satellite leaves a factory;

the satellite digital twinning subsystem 504, configured to: and through interaction with the satellite design research and development subsystem, the satellite production manufacturing subsystem and the satellite remote control and remote measurement subsystem, the satellite design research and development subsystem, the satellite production manufacturing subsystem and the satellite remote control and remote measurement subsystem are determined and the three-dimensional digital model is displayed in the running stage of the satellite production manufacturing process based on the satellite resource database.

For the system shown in fig. 5, it should be noted that the satellite design and development subsystem 501, the satellite production and manufacturing subsystem 502, and the satellite remote telemetry subsystem 503 cover the whole flow business of the satellite from design to production and manufacturing to testing, even in-orbit maintenance; the corresponding three-dimensional data model, or digital twins, constructed by the satellite digital twin subsystem 504 needs to be determined and displayed in combination with the operation phase of the subsystem corresponding to each applicable scene.

Based on the above-mentioned resource database 10 and the full flow service exhibited by the digital satellite production manufacturing system 50, referring to fig. 6, for the satellite design and development subsystem 501, the satellite production manufacturing subsystem 502, the satellite remote telemetry subsystem 503 and the satellite digital twin subsystem 504 in the digital satellite production manufacturing system 50, the design process thereof may include:

s601: aiming at the satellite design research and development subsystem 501, when an expected whole satellite model or a part model cannot be inquired from the whole satellite model library and the part model library in the whole satellite model selection design stage, whole satellite modeling and/or part modeling are/is carried out by combining the part model library, the whole satellite model library, the design resource library and the process resource library, resource data in the part model library, the whole satellite model library, the design resource library and the process resource library are updated in the modeling process, and archive data of a corresponding part model or a whole satellite model in the part archive library and the whole satellite archive library are updated;

s602: aiming at the satellite production manufacturing subsystem 502, decomposing a production task based on a process resource library and issuing the production task to corresponding production stations, wherein each production station executes production material receiving and production assembly based on a component archive library and a whole satellite archive library;

s603: for the satellite production and manufacturing subsystem 502, performing finished product testing based on the testing resource library to control the production and assembly quality;

s604: for the satellite remote control and telemetry subsystem 503, completing a test task before the whole satellite of the target satellite finished product leaves the factory based on the component archive library, the protocol resource library and the test resource library;

s605: and aiming at the satellite digital twin subsystem 504, generating a three-dimensional digital model based on the component model library and the whole satellite model library, acquiring the operation data of the in-orbit satellite according to the protocol resource library, and monitoring and displaying the operation state of the in-orbit satellite.

For the technical solution shown in fig. 6, in combination with the information flow direction schematic diagram shown in fig. 7, specifically:

the satellite design research and development subsystem 501 queries resource data in the whole satellite model library from project requirements when the whole satellite is selected; when the whole satellite model library does not have whole satellite model data meeting project requirements, the whole satellite collaborative modeling is required, and at the moment, a component model library, a whole satellite model library, a design resource library and a process resource library are required to provide data support, for example, in the process of collaborative modeling of the whole satellite, component information contained in the whole satellite model library also needs to be subjected to component model selection, and then the component model library is inquired; if the required component model does not exist in the component model library, then component collaborative modeling is required, and at the moment, the component model library, the design resource library, the process resource library and the protocol resource library are also required to be supported to construct the component model, and the whole satellite model is constructed after the component model is constructed, and in the process of modeling the component model and the whole satellite model, the related resource library can be subjected to bidirectional iterative updating based on the construction process of the satellite design research and development subsystem 501. In addition, after the final design and development of the component model and the whole star model are finished, corresponding component information and whole star information are generated and stored in a corresponding component archive and a whole star archive. The information in the two archives has a unique archive number, so that the uniqueness of the information in the whole system is guaranteed.

The production task decomposition of the satellite production manufacturing subsystem 502 requires support of a process resource library, while production material taking and production assembly requires support of a component archive and a whole satellite archive. Furthermore, in the satellite manufacturing subsystem 502, the finished product testing requires support of a test resource library. And bidirectional iterative updating is carried out aiming at the test resource library in the finished product test process.

All functions of the satellite remote control and telemetry subsystem 503 need support of a component resource library and a protocol resource library, and the ground automated batch test for a single machine or a whole satellite also needs support of a test resource library and the test resource library needs bidirectional iterative update.

All functions of the satellite digital twin subsystem 504 need support of a component model library, a whole satellite model library and a protocol resource library, so that the functions of constructing a digital twin and a scene, performing simulation analysis, monitoring a monitoring state and the like are realized.

Based on the design process shown in fig. 6 and the information flow trend shown in fig. 7, it should be noted that the four subsystems all need to use the satellite resource database 10 as a data base, and the four systems not only use the resource data in the resource database 10 but also iteratively update the satellite resource data related to the database in the process of the full-flow service, so as to continuously refine and expand the resource data in the resource database 10. The continuously improved and expanded satellite resource data can help a system executing the full-flow business to make a quick decision and operate, so that the research and development period of the satellite can be effectively shortened, and the production efficiency of the satellite is improved.

In addition, it should be noted that, in combination with the association between the database and each subsystem shown in fig. 7, the production and assembly tests of the satellite can be integrated, and a plurality of modules cooperate to work in a unified manner, based on the component model library, the component archive library, the whole-satellite model library, and the whole-satellite archive library, the whole process of the satellite production and manufacturing and testing links can be completed, and the circulation of the intelligence can be realized. For example, taking a satellite assembly production link performed by the satellite production manufacturing subsystem 502 as an example, when a problem occurs in the assembly process, such as an excessively large area occupied by a certain satellite component and no assembly, the assembly center is responsible for feeding back information update of the component of the satellite, and may add a gasket or modify parameter information such as an installation angle, the assembly center is responsible for modifying the component information, when the component information is updated, the component model library information is modified, the modification process drives the satellite remote control and remote measurement subsystem 503 to prompt the satellite remote control and remote measurement subsystem 503 that the component model is modified, all production manufacturing links related to the satellite can be modified intelligently, so that intelligent assembly and finished product testing are realized, and the operation of the whole process is realized intelligently.

In addition, it should be noted that, in combination with the composition and architecture design of the resource database 10 shown in fig. 2 to fig. 4, it can be seen that the more important component model library, component archive library, whole star model library and whole star archive library in the resource database 10, and in combination with the above description of the technical solution, the archive information in the component archive library or the whole star archive library corresponds to each component model or whole star model in the component model library or whole star model library, that is, the most important or core database in the resource database 10 is the component model library and the whole star model library. Further, since the whole star model is composed of component models, it can be understood that the component models are even more important than the whole star model.

Based on this, for the component model, the traditional satellite component model library only lists the information of all the component models, and there is little interaction of design information flow, and the interaction logic relationship between the component model library, the component model archive, and the whole-satellite model library and the whole-satellite archive library. In the embodiment of the invention, in the full-flow service process from design, production, manufacture, assembly and test to final on-orbit operation and maintenance of the satellite, all databases are expected to be connected in series based on all services, information among all databases can be supplemented in different links, and the different databases can also carry out information interaction and acquisition synchronization and finally serve as a core basis for design and production integration of the digital satellite. Based on this, for the building of the component model library, the component model information needs to be processed, for example, the component information is abstractly modeled, and therefore, in some examples, the component models in the component model library may include: four types of models, namely a protocol model, an interface model, a structural model and a behavior model. For these model types, the process of building a library of component models may include:

for the protocol model, in the component model of the satellite, the protocol information corresponding to different models is different, and the protocol information corresponding to the same model is also different for different manufacturers, and for different protocol information, a unified management needs to be performed. Based on different protocol format information, considering compatibility, expansibility and the like, the protocol information modeling processing is carried out on the component model, in the embodiment of the invention, the protocol model information is used as an attribute of the single-machine component model, so that the protocol model can be adapted to protocols of different models and different manufacturers, and meanwhile, after the protocol model is built, the protocol information and the component model are correspondingly bound, thereby facilitating the subsequent testing link. For example, in the process of testing a component model, when a protocol needs to be issued, the protocol information of the component model can be directly checked, that is, the protocol information can be used as a protocol information identifier and provided for a protocol resource library of a satellite testing link, and the synchronization of the protocol information of the component is realized from the protocol resource library, so that the protocol control and the like of the component model in a remote measuring and remote control stage and an on-orbit maintenance stage at a later stage are facilitated, and in general, the specific component protocol information and the component are bound to be used as a protocol source of all satellite design and production links.

For the interface model, the interface model of the component can be designed by abstracting the interface model of the component so as to realize interface calling between the components and the whole satellite; in addition, interface model information of the components can be reserved, so that in the design process of the whole satellite and the design process of the subsystems, when the interfaces of the models need to be called and various libraries are communicated, the information calling and synchronization are realized by reserving the interface models.

For the structural model, abstract modeling can be performed on structural information of the component, the abstract modeling mainly comprises information of a 3D model, a part diagram, a whole satellite assembly diagram and the like, and the structural model and the information of the component can be conveniently checked in each link process in the later stage, such as the satellite digital twin subsystem 504.

For the behavior model, abstract modeling can be performed on the behavior of the component, and the attitude behavior parameters of the component model are recorded, so that later-period dynamic calculation is facilitated, and the specific attitude information of the component model in the whole satellite operation stage is calculated.

It should be noted that, since the whole satellite is composed of a plurality of component models, the design of the component model library not only needs to include all the component model information, but also can get through the information flow of the business process design and the various libraries, so that the model library of the satellite can be efficiently and quickly managed, and the overall design of the satellite is accelerated.

Meanwhile, the corresponding component archive library can be generated through the component model library information, so that a basis is provided for the production assembly and the whole satellite test of the satellite at the later stage.

Based on the above construction composition of the component model library, in some examples, the whole star model library may also perform modeling decomposition, and the component models in the whole star model library may include: the method comprises the steps of forming a model, a behavior model, a connection model and a characteristic model, managing a whole satellite model base based on the models in a unified and digital mode, efficiently and quickly completing the satellite production and manufacturing links, and realizing the completion of all the links of satellite design and production and manufacturing based on the whole satellite model base and archive information. For these model types, the build process may include:

for the formation model, the whole satellite comprises all the part model information, and the whole satellite is composed of a plurality of part models, so that the contained part model information is uniformly formed into the formation model in the whole satellite model library to serve as the characteristics of the whole satellite, the use in the later satellite design and production and manufacturing processes is convenient, and the communication of all library links is realized.

For the behavior model, because the characteristic attribute information of each satellite is different, each satellite has the characteristic behavior model characteristic thereof, the characteristics can be used in each link of satellite design and production, and the attitude indexes of different satellites are different, the whole satellite can be used as a model, and the abstract trip is the model characteristic.

For the connection model, because the whole satellite is composed of a plurality of components, and the different components are in associated communication, or the whole satellite is connected with each model through a power-on cable network, the connection between the different component models can abstract out a connection model, and the unified modeling management of the connection between the satellite components is realized.

For the characteristic model, different satellites have different characteristic attribute information, the different characteristic information is abstracted out for modeling, and the characteristic model information of the whole satellite is formed, so that later links such as whole satellite design, production and manufacture surround the characteristic information to be expanded, and unified management of the different characteristic information of the different satellites is realized.

It should be noted that the whole satellite model library depends on the component model library, the component model library is generated according to the selected component model information in the whole satellite design process, and in different satellite production links, because the information added to the whole satellite model library is rich and different, the whole satellite library can be gradually perfected by adding some product-level information and production-level information, and simultaneously the archive information of the digital satellite is generated.

Based on the construction of the component model library and the shaping model library, the digital model design process for the component model and the whole star model can be as shown in fig. 8, specifically:

for the satellite design research and development subsystem 501, in the part model selection/design phase, regarding the design of the part model library, first, depending on ids attribute information of the part, specifically including information parameters of machine, heat, electrical interface and the like, preliminary model library information for the model can be established by reading the entry system, then, each department designer can directly acquire the part model information from the existing part model library through the satellite design research and development subsystem 501 according to specific whole satellite parameter indexes, in the part model selection phase, if the adopted part model does not exist in the part model library, a new part can be added into the part model library. In the process, designers and a supply chain can adjust the attribute information of some component models through the calculation parameter information of each department, and the adjusted parameter information can be used as a component-level parameter list, so that a component model library is enriched and updated, and respective modeling information is added.

In the whole satellite design stage, each department designer can obtain whether the parts selected by each subsystem meet whole satellite index information or not by utilizing the satellite design research and development subsystem 501 according to specific part parameter information through intelligent calculation and analysis, and then carry out the processes of part adjustment and information iteration, wherein the process can generate a product-level parameter list of the parts as attribute information of a part model, and the product-level parameter list is added into a part model library to enrich and update the part model library; meanwhile, the model information base of the component is finally determined by performing cooperative operation, iterative modification and the like on the single-machine component model base among different satellite subsystems, such as a structure system, an attitude and orbit control system, an electric system and the like. After the satellite is designed, the whole satellite information base of the satellite can be generated by relying on all component model information bases required by the satellite, and all attribute information of the whole satellite of the satellite, including but not limited to own unique information and information of all component models adopted, and the like, is added in the whole satellite information base. In addition, a component archive library is generated according to the model information library to guide a production department of the satellite, a BOM list of the components is obtained through selection of the component archive library, and a production assembly process is guided.

In the process of the satellite design research and development subsystem 501, parameter information of the component model is supplemented, and a production-level parameter list is provided, wherein the production-level parameter list is supplemented and enriched into the component model library based on the production-level parameter list and the bottom-level data synchronization between the bottom-level process database and the component model library, that is, the component model library is still supplemented and enriched in the process of the process design, at this stage, the final version of the component model library can be basically determined, at the later satellite production stage, the component model library is not operated, and at the same time, the component archive library is generated by combining the production-level parameter list and depending on the final version of the component model library, and at the later satellite production preparation stage, the assembly test stage and the on-orbit maintenance stage, the component archive library and the whole satellite archive library are mainly modified.

For the satellite production manufacturing subsystem 502, in the production preparation phase of the satellite, the platform master, the engineer, the supply chain, the assembly test center and the warehouse can still supplement the archive data information of the component model in the production process of the whole satellite, synchronize to the component archive through the synchronization of the information between the bottom layer libraries based on the information of the supply product library, the equipment test library and the like, and then update the information of the whole satellite archive by combining the information of the component archive.

For the satellite production and manufacturing subsystem 502, in the satellite assembly test stage, parameter modification or parameter information supplementation and the like can be performed on the model for the problems in the assembly test, and each link provides archive data, supplements all parameter information into a component archive, and simultaneously updates the whole satellite archive.

For the satellite remote control and telemetry subsystem 503, in the in-orbit maintenance phase of the satellite, the platform owner updates in-orbit information of the satellite, such as protocol parameter information, and supplements the in-orbit parameter information to the component archive, and updates the whole satellite archive at the same time.

It should be noted that the component list BOM table selected from the component archive library can be used as an input of the BPM system to get through based on the component model library, the design resource library, the protocol resource library, the process resource library and the test resource library set forth in the foregoing technical solutions, so as to guide the satellite production and assembly process, and to implement the production and circulation of the digital satellite in the final satellite testing link after the assembly is completed.

Based on the technical scheme of the embodiment of the invention, communication between the component model library and the whole satellite model library is realized, and the whole satellite model library and the whole satellite archive library are combined as a basis to realize communication of each link of satellite design and production and manufacture, and even can comprise other databases related in the manufacturing process, such as a BPM-BOM library, a satellite software configuration item library, an entrance and exit account library, a supply chain purchasing information library, an assembly center component entity library and a production line, and a satellite test system library of a test center to realize communication of information among all the libraries.
