Independent computing and storage spaces are built in combination with the need for mutual isolation, and static and dynamically separated computing and storage resources are built.

[0013] Furthermore, in step 2, the distributed heterogeneous processing resources are abstracted into containers, a logical soft bus is defined, and a separate control plane and data plane interconnection architecture is constructed, as follows:

[0015] Step 2.2, using the partial circuit reconfiguration technology of the field editable logic gate array, the programmable logic gate array is divided into a static area and multiple dynamic areas, the static area runs the basic configuration circuit and can match various channel software; the dynamic area runs different channel algorithms;

[0016] Step 2.3, storing different channel software in the logic storage unit, and controlling the reconstruction configurator through the programmable logic gate array resource management module to load the different channel software in the logic storage unit into the specified planning area, thereby realizing dynamic reconstruction of the channel software;

[0017] Step 2.4: Through the resource management module, the local operation of the firmware, processing software, and protocol software of each hardware module in the channel software is called in the memory resources to complete the operation of the satellite channel software.

[0018] Furthermore, in step 3, the channel software is divided into sub-functions according to the interface, function, logic, and state attributes, and is segmented, organized, and packaged to form a callable algorithm library, as follows:

[0019] Step 3.1, the channel software set includes four categories: narrowband waveform, broadband waveform, protection waveform and customized waveform, which are partitioned and stored according to the categories of calculation processing, logic processing and drive processing;

[0084] Example

[0085] The present embodiment provides a satellite channel online upgrade method based on regionally reconfigurable components that can be arranged, that is, it includes a satellite communication channel hardware resource regional reconstruction process, a processing resource arrangement and deployment process, a channel software component segmentation process, a channel software automatic online upgrade process, etc., which are further described below according to the diagram.

[0086] like Figure 1 The schematic diagram of the satellite channel hardware resource area reconstruction process mainly includes satellite channel resource area planning and reconstruction. The specific steps are as follows:

[0087] ① Divide the physical hardware according to application operations, logical operations, logical storage, interface transmission and reception, exchange processing and other resources, and build independent computing and storage spaces based on the need for mutual isolation, and build solid-state and dynamic separated computing storage and other resources.

[0088] ② Based on the standardized logic bus design, under the arrangement and control of the control reconstruction configurator, the mapping between reconfigurable physical hardware resources and channel software or high-level protocol software is realized, and a configurable parameter transfer path is established.

[0089] ③ Each module is divided into a static area and multiple dynamic areas. The static area runs the basic configuration circuit, and the dynamic area runs different applications, logic, transmission and reception and other operations.

[0090] ④ Load different channel files into the specified dynamic area to achieve dynamic reconstruction of the channel software. The entire configuration process does not affect other working areas.

[0091] ⑤ Through the resource management module, the local operation of the firmware, processing software, and protocol software of each hardware module in the channel software is called in the memory resources to complete the operation of the satellite channel software.

[0092] like Figure 2 The satellite channel software component library reconstruction deployment architecture diagram mainly includes the collection of the source code resource library of the channel software, the segmentation and organization of the source code to form a software component library, and the combination and replacement of the component library to reconstruct it into an executable program. The specific steps are as follows:

[0093] ① Channel software collection, consisting of four categories: various narrowband waveforms, broadband waveforms, protection waveforms and customized waveforms, is partitioned and stored according to categories such as calculation processing, logic processing, and drive processing.

[0094] ② Through the design of software system architects and the compilation of library files by software designers, sub-functions are divided according to attributes such as interface, function, logic, and status to form a channel software component library, which includes a general encoding library, decoding library, modulation and demodulation library, channel estimation library, synchronization algorithm library, access control library, business processing library, network enhancement library, information interaction library, component management library, as well as special processing libraries such as high dynamic, multi-occlusion, low burst, and hidden carrier.

[0095] ③ Software operation system construction, build the hardware environment according to logical operation resources, application operation resources, logical storage resources, flash memory resources, exchange processing resources, interface transceiver resources, etc., and establish system files such as driver operation, health management, file transfer, and information transmission of each module.

[0096] ④Construct the software message passing environment. According to the communication functions abstractly encapsulated by the hardware platform, realize the message frame transmission interaction through packet switching or shared memory, and establish the communication driver modules of each module.

[0097] ⑤ Software library file loading environment construction. When the running environment and transfer environment are built, the required encoding library, decoding library, modulation and demodulation library, business processing library, and special processing library are called by starting the system call component management library, and the startup timing construction process is entered according to the calling strategy.

[0098] ⑥ Software timing startup: According to the specific characteristics of hardware, driver, information interaction, etc., the startup file is written as the timing file for the subsequent system self-startup to complete the reconstruction process of the channel software.

[0099] like Figure 3 The automatic online upgrade flow chart of satellite channel software mainly includes the steps of connecting to the upgrade system, pre-upgrade verification, real-time detection, post-upgrade verification, and one-key rollback. The specific process is as follows:

[0100] ①Connect the upgrade system. Since satellite communication is a non-real-time online system, the selection of upgrade channels is divided into two ways: on-demand application and online real-time distribution. On-demand application means applying for a dedicated satellite upgrade channel when an upgrade is required, actively customizing the upgrade software, and triggering the automatic upgrade process after the user confirms. Online real-time distribution is to arrange the online upgrade automatic process through the idle time slot of the control channel that must be reserved for the system to maintain normal operation.

[0101] ② Customized software and software import, on-demand application upgrade method, users can trigger the menu information in the software upgrade warehouse, and customize the upgrade operation process of the upgrade project through the user's subjective choice. After the customization is completed, the satellite channel terminal equipment imports the software package to be upgraded to trigger the automatic upgrade process. The online real-time distribution upgrade method is to compare the system version online in the form of a system upgrade package, and automatically determine the upgrade operation process after a two-way match based on the system version setting strategy and the user upgrade strategy. The satellite channel terminal equipment imports the system upgrade package to trigger the automatic upgrade process.

[0102] ③Verification before version upgrade, on-demand application or online real-time distribution upgrade methods all use the version verification program in the automatic upgrade process to verify the upgrade file, and use a prompt window to give the verification result. If it fails, it will prompt the verification failure and whether it needs to be upgraded again, and delete the wrong upgrade version at the same time; if it succeeds, it will display success and prompt whether to start the upgrade. If you choose to upgrade, it will enter the automatic upgrade process. After successfully entering this step of the automatic upgrade process, the upgraded satellite channel of the satellite channel terminal can be dismantled or the upgrade resources can be recycled.

[0103] ④ Process recording and real-time error detection. After the upgrade starts, data recording and error detection are performed according to the process points pre-set by the upgrade software. If an error occurs, the one-key rollback step is entered, and user information is given in the form of a prompt box; if no process point error occurs, the software automatic upgrade process will continue until the upgrade step is completed.

[0104] ⑤Verification after version upgrade. After the automatic upgrade step is completed, the installation environment and installed software are verified according to the checkpoints pre-set by the software. If an error occurs, enter the one-key rollback step and provide user information in the form of a prompt box; if no checkpoint error occurs, the software upgrade is completed.

[0105] ⑥ One-click rollback: uninstall the installation environment and installed software according to the rollback point pre-set by the software. After the uninstallation is completed, the user will be prompted whether to delete the upgrade package and upgrade again. If necessary, repeat the on-demand application in step ①. If not, the upgrade process ends and automatically enters the online real-time distribution in step ①.

[0106] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
