As an important component of a network information system, the space-based information system has unique space-time advantages and is more prominent in the construction of smart cities and the like in the future.
Because of the important strategic position of the space-based system, the space-based system is developed at home and abroad without much power. The space-based system is the independent establishment stage of each functional space-based system at the earliest. The typical United states is built into 43 space-based electronic reconnaissance satellites represented by 'keyhole' and the like, more than 30 space-based information transmission satellites represented by 'advanced extremely high frequency' and the like, and navigation satellites represented by a GPS (global positioning system) to provide reliable information collection, military communication and navigation positioning service capability for military combat; three satellite application systems of satellite communication, satellite earth observation and satellite navigation positioning are established and formed in China.
Aiming at the problems that the space-based systems which are independently constructed cannot effectively realize interconnection, intercommunication, interoperation and the like, the space-based systems enter a global networking interconnection stage. Information interconnection and sharing among space-based systems are realized through a global information grid, a comprehensive space communication system (SCaN), a joint space operation center task system (JMS) project, an integrated command and control (ISC2) project and the like in the United states, and the quick response capability of the army combat is greatly improved; at present, China is developing a world-wide integrated information network vigorously, which is composed of a space-based backbone network, a space-based access network, a foundation node network and the like, and is interconnected and communicated with a ground internet and a mobile communication network to construct a world-wide integrated information network system with global coverage, random access, on-demand service, safety and reliability.
The development of space-based systems and networks lags behind the ground seriously for a long time, and the problems of single function, isolated information, dispersed resources, slow response and the like which influence diversified and intelligent combat application are still outstanding. The space-based system generally adopts a ground-based management and control, operation and maintenance and information processing mode, and the operation of the system depends heavily on the ground. Due to the limitation of domestic station arrangement, the problems of discontinuous operation control, untimely control and the like inevitably exist due to the insufficient visible arc sections of space-based systems such as satellites and the like, and the service requirements of globalization and all-time service cannot be met. The ground-based information comprehensive processing method causes problems of slow response speed, poor safety and the like, and is difficult to provide safe, reliable, fast and real-time space-based resource service.

Fig. 1 shows an intelligent space-based system based on a cloud pool end, which is disclosed in this embodiment, and implements cloud management service, pool aggregation resource, and end management service by using a service mode of "cloud + pool + end". The cloud is a space-based cloud platform and is responsible for managing task requests initiated by users. The pool is a unified virtual resource pool established after virtualization, namely a space-based resource pool, which is a middle layer in the architecture and is also a core connection point of a cloud and an end, and provides the capability of realizing resource sharing with other satellites. The end is the object of the final resource service, including equipment and personnel, such as aircraft, naval soldiers, etc.
Fig. 2 is a schematic diagram of a pooling process of space-based resources in this embodiment, which specifically includes the following processes:
(1) satellites in space-based systems are all nodes with certain computing, storage, sensing and execution resources. The satellite nodes are connected into a distributed satellite cluster through an inter-satellite network to form a space-based network.
(2) Each node in the space-based network firstly virtualizes own resources into general computing resources, storage resources, network resources, sensing resources and execution resources through a resource virtualization technology, and the resource virtualization scheme based on the KVM is adopted as same as the ground virtualization technology, and the virtualization layer is directly realized on a physical hardware layer through a virtualization module embedded in an operating system. While virtualization of computing, storage, and network resources can be achieved through the virtualization layer. The virtualization of the sensing and execution resources can be abstracted into a logical device by loading a device driver, can be uniformly expressed into a universal logical resource by adding tags and interface packages to the sensing and execution resources, and realizes the virtualization of the sensing and execution resources.
(3) Virtual resources of each node are integrated and pooled into a unified CPU pool, a storage pool, a sensing pool, an execution pool and a network resource pool through a distributed cloud network operating system, and pool-based resources are achieved. The distributed cloud network operating system can share the resources scattered on each satellite into a whole, the most detailed granularity resource of the hardware resource is realized through the virtualization module in the operating system, the demand-oriented calling according to the demand is realized, and the operation can be reduced to increase the resource configuration and the use flexibility.
(4) Five resource pools in the resource pools respectively establish own resource catalogs and indexes, and a unified resource catalog and a universal indexing method are externally provided, so that the logical resources can be mapped to the satellite which actually shares the resources through the resource catalogs and the indexes.
Fig. 3 is a schematic layered diagram of the cloud management service of the space-based cloud platform in this embodiment, that is, a process of interfacing resources of the space-based resource pool to serve the service. The method comprises the following specific steps:
(1) and the resources in the space-based resource pool are accessed into the adapter through the virtual resources, so that a using method is provided for the upper layer calling. The virtual resource access adapter is equivalent to an access channel of a resource pool. For computing resources, the virtual resource access adapter is equivalent to access management of contents such as CPU time slice scheduling and memory addresses. As for the storage resource, the virtual resource access adapter is equivalent to access management of contents such as a storage block and IO read/write. As for network resources, a virtual resource access adapter corresponds to access management of contents such as a network port, a route, and a gateway. As for the sensing resource, the virtual resource access adapter corresponds to access management of the drive of the sensor, the data read/write interface, and other contents. The virtual resource access adapter corresponds to access management of contents such as driving of an executor and execution command control for an execution resource.
(2) And various resources are accessed and uniformly packaged into an API (application program interface), so that a scheduling interface is provided for scheduling of various resources. The scheduling of each type of resources needs to use a self-encapsulation method, so that the problems of conflict and the like caused by scheduling confusion of the resources are avoided. At this step, it can be packaged as an elastic computing API, an elastic storage API and an elastic network API, and a general sensing API and a general execution API, respectively. The first three categories of resources, namely computing, storage and networking resources, are more resilient. The flexibility here refers to the performance of the three types of resources in scheduling can be large or small, and scheduling is performed according to the service requirements. The latter two types of resources, namely sensing and execution resources, are heavily versatile. The general purpose here means that the resources can be not limited by electric and physical interfaces, etc., and it provides a general scheduling method, and the resources can be called as required according to the space-time property of the satellite when in use.
(3) And various resources are comprehensively and cooperatively scheduled by the scheduling service. Each type of resource is not individually scheduled, but is comprehensively and cooperatively scheduled by a unified cooperative scheduling process according to a certain scheduling strategy, such as a plurality of types of scheduling strategies with minimum queue time, minimum power consumption and the like, so that the aim of efficiently utilizing the resources is fulfilled.
(4) The resources are matched with the service requirements. And scheduling resources by the service scheduling service, completing the matching of various service resource requests of the space-based cloud application to specific resource services by the service resource matching management, realizing the mapping from the service to the resources and establishing the service connection between the service and the resources. And integrating the processes, namely realizing the function of the space-based cloud platform management service.
In the aspect of end-sharing service, the terminal accesses to the satellite and obtains the schematic diagram of the sky-based information service as shown in fig. 4. On one hand, terminals such as airplanes, naval vessels, personnel and the like can access the internet, and corresponding data products and information services are obtained through a ground cloud data center. The ground cloud center is directly connected with the ground station to manage and control the space-based system or acquire the space-based information service. On the other hand, a terminal with authority may send a resource service request to a space-based system through a small satellite access device carried by the terminal or a ground satellite access network, such as a satellite gateway, a base station, or the like, so as to obtain a corresponding space-based service. An edge server is designed and added in an access network, and certain resources such as calculation, storage and the like are introduced, so that certain edge processing can be performed on requests and services, the time delay is reduced, and the service quality is provided.
Referring to fig. 5, for a further implementation manner of the space-based resource pool in this embodiment, the space-based resource pool may be further constructed to form a space-based resource library based on the five types of physical resources, i.e., the computing resource, the storage resource, the network resource, the sensing resource, and the execution resource, and in addition to the platform resource and the software resource in the cloud platform. The resources of the space-based resource library are divided into three categories according to the software and the hardware of the resources, and the three categories are as follows:
(1) physical type: the facilities are space-based hardware resources, all subsystems and modules of the satellite are decoupled in function by subdividing the satellite platform and the payload functional structure, and the hardware structures with the same or similar functions are organically fused to form a hardware resource pool. The hardware structure of the satellite can support software calling, and can also realize cooperative scheduling among networks through a uniform interface.
Common infrastructure resources include computing resources, storage resources, network resources, sensing resources, and energy resources; and the satellite local resources are execution resources. Specifically, the infrastructure resources are as follows:
computing resources: CPU, ARM, DSP, GPU, PowerPC, etc.;
storage resources: solid state, SRAM, Flash, EEPROM, etc.;
communication resources: radio frequency communication module, laser communication module, quantum communication module, (frequency, channel, etc. are parameters of communication facilities);
executing the resource: reaction wheels, magnetic torquers, star sensors, etc.;
sensing resources: gyroscopes, accelerometers, magnetometers, thermistors, cameras, radio frequency receiving equipment, and the like.
(2) Platform class: on the platform level, a space-based cloud storage platform is established based on distributed storage, dynamic deployment and dynamic reconstruction of storage resources are supported, and high-speed data storage and on-demand data service can be realized. The stored data resources mainly comprise space-based time-space information, satellite state information, image information, a knowledge base and the like. The knowledge base is the knowledge stored by each satellite, and the knowledge can be pre-stored models, rules and the like for executing tasks and completing data processing, and can also be useful knowledge extracted by a certain method from information of running and executing tasks of the satellite in long-term running. Specifically, there are resources such as data and databases, knowledge/rule bases, spatio-temporal data, image data, system state data and files.
(3) Software class: at the software resource level, the software resource refers to application software, system software and a container mirror packaged based on container technology, which can realize specific functions. The software resources in the embodiment support direct calling and migration application of the space-based system to the existing software resources. The software in this embodiment is not limited to the program or mirror image running on the satellite, and may be dynamically deployed according to resource requirements, and run on other satellites, so as to implement flexible definition and on-orbit reconstruction of the satellite functions. Specifically, there are support programs, application programs, system programs, libraries, mirror images, and the like. The software resources are stored in a satellite local software repository.
The platform type and software type resources belong to renewable resources, partial data type and software type in a space-based system. The resources have huge data, more convenient sharing and higher times, so that in a bandwidth-limited space-based network, the resources can be shared efficiently only by a request-response-based mode. The resource scheduling is also realized through a resource management module in the cloud platform. The resource management module in the space-based cloud platform is a resource management module in a distributed operating system, is a distributed resource manager in the space-based cloud platform, is a process distributed in each satellite, and is responsible for managing and scheduling resources, that is, as shown in fig. 6. When a resource management module on a satellite receives a certain resource request, the resource management module judges whether the resource request is the resource requirement of a physical type or a platform/software type, and then searches through a resource directory of the satellite. And if the resources are consistent, responding to the request, then establishing connection, sending the platform class or data class resources responded, and completing resource sharing.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
