[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0023] Embodiment 1

[0024] Figure 1 A functional module diagram of a resource management system for a communication satellite system provided by an embodiment of the present invention, such as Figure 1 As shown, the system includes: a system resource publishing module 10, an application information management module 20 and a resource allocation and planning management module 30.

[0025] The system resource publishing module is used to obtain the latest resource information of the communication satellite system and publish the resource information on a designated website; the resource information includes: orbital elements, ephemeris and idle windows of each communication satellite.

[0026] The application information management module is used to receive communication satellite resource use applications submitted by the user center through the designated website, and to perform a legality check on the communication satellite resource use applications, so as to send the legal communication satellite resource use applications to the resource allocation and planning management module.

[0027] The resource allocation and planning management module is used to process legitimate communication satellite resource use applications based on preset conflict resolution rules, obtain a first processing result, and feed back the first processing result to the user center; wherein the first processing result includes: application success, application failure.

[0028] The resource management system provided by the embodiment of the present invention is specifically in the form of a portal website system. As one of the ways for the user center to interact with the communication satellite system, the portal website system is responsible for publishing the latest resource information of the communication satellite system to all user centers in real time in the form of a portal website, receiving and processing communication satellite resource use applications submitted by each user center, publishing resource allocation results, etc.

[0029] In the embodiment of the present invention, the system resource release of the communication satellite system includes: communication satellite orbital elements release, communication satellite ephemeris release, and communication satellite idle window release. Specifically, the system resource release module obtains the latest communication satellite orbital elements from the website database and releases them on the designated website. If a request for downloading the communication satellite orbital elements is received from the user center, the system resource release module reads the latest orbital element information from the website database in real time, and then saves the information in an orbital element file of a designated format, and finally provides the user center with a download link for the orbital element file.

[0030] The system resource publishing module is also used to obtain the latest communication satellite ephemeris from the website database and publish it on the website. If a request for downloading communication satellite ephemeris is received from the user center, the system resource publishing module reads the latest ephemeris file in the website database in real time and then provides the user center with a download link for the ephemeris file.

[0031] The system resource publishing module is also used to publish the idle window of the communication satellite. The space window is the time window when the communication satellite resources are not used by users. When publishing the idle window, the non-idle window of the communication satellite will also be displayed. In the embodiment of the present invention, the non-idle window includes: a user target planning window and an internal occupation window. The user target refers to various spacecraft, long-range reconnaissance aircraft, electronic reconnaissance ships, etc. equipped with communication satellite terminals. Through the user target terminal, the communication satellite can establish an intersatellite link with the user target, and complete the data transmission between the user center and the user target through this intersatellite link, or implement measurement and control of the user target. The user center refers to the engineering measurement and control center or business measurement and control center, application center, and other users of the user target, such as the control center or command and control unit of the ship, unmanned aerial vehicle, etc. equipped with the user target terminal. The user target planning window is the time window in which the user target plans to occupy the communication satellite resources, and the internal occupation window refers to the time window in which the communication satellite system plans to occupy the communication satellite resources.

[0032] In an embodiment of the present invention, the idle windows of a communication satellite are displayed in units of beams. For example, if a communication satellite provides three beams to the outside, then when publishing idle windows, the communication satellite will correspond to the idle window distributions of the three beams, namely, the idle window distribution of the first beam, the idle window distribution of the second beam, and the idle window distribution of the third beam.

[0033] After the system resource publishing module publishes the latest resource information of the communication satellite system on the designated website, all user centers can intuitively view the idle status of the communication satellite system resources on the designated website. Based on this, each user center can refer to the idle windows of each communication satellite according to its own task requirements, and after calculation, initiate an application for the use of one or more communication satellite resources that can complete the task, thereby effectively reducing the blindness of the user center in applying for communication satellite resources.

[0034] After receiving the communication satellite resource use application sent by the user center, the application information management module first performs a legality check on the application. The embodiment of the present invention does not specifically limit the items for the legality check, and the user can set it according to actual needs. If it is determined that the application is an illegal application, the application information management module will prompt the user center in the form of a pop-up dialog box to indicate the reason why the application is illegal; if it is determined that the application is a legal application, the application information management module needs to send it to the resource allocation and planning management module, and then wait for the processing result of the resource allocation and planning management module in a polling manner.

[0035] After receiving the legitimate communication satellite resource use application, the resource allocation and plan management module will process the legitimate communication satellite resource use application according to the preset conflict resolution rule, obtain the first processing result and feed it back to the user center. When allocating communication satellite resources and formulating resource use plans, there are many known conflict resolution rules in the art. The embodiment of the present invention does not specifically limit the content of the preset conflict resolution rules, and the user can set them according to actual needs.

[0036] After obtaining the first processing result, the application page of the user center will be updated accordingly. Optionally, the first processing result will be displayed on the interactive interface of the designated website, and the idle window release page and the communication satellite resource usage plan page of the system resource release module will be updated as appropriate. Specifically, if the first processing result is a successful application, the idle window release page and the communication satellite resource usage plan page will be updated according to the application information in the communication satellite resource usage application; if the first processing result is a failed application, there is no need to update the above two pages.

[0037] In addition, for legitimate applications for the use of communication satellite resources, the application information management module is also used to save the application information as a file that meets the interface requirements, store the file in the website file table of the website database, and store the file number in the notification message table in the website database to provide log records for subsequent information tracing.

[0038] The embodiment of the present invention provides a resource management system for a communication satellite system, which includes: a system resource publishing module, an application information management module and a resource allocation and planning management module; the system resource publishing module obtains the latest resource information of the communication satellite system and publishes the resource information on a designated website; wherein the resource information includes: the orbital elements, ephemeris and idle window of each communication satellite, so that all user centers can intuitively view the idle situation of the communication satellite system resources on the designated website, effectively reducing the blindness of the user center to the communication satellite resource application. The application information management module receives the communication satellite resource use application submitted by the user center through the designated website, and performs a legality check on the communication satellite resource use application, so as to send the legal communication satellite resource use application to the resource allocation and planning management module, and the resource allocation and planning management module processes the legal communication satellite resource use application based on a preset conflict resolution rule, obtains a first processing result, and feeds the first processing result back to the user center. The resource management system of the communication satellite system simplifies the interaction process between the user center and the communication satellite system, improves the interaction capability of the communication satellite system and the resource utilization rate of the communication satellite system, thereby improving the user experience.

[0039] In an optional implementation manner, the publishing forms of the idle windows include: graphics, tables; the types of idle windows include: public idle windows, directional idle windows.

[0040] The idle window includes the following two display modes under the graphics publishing form: all user target display mode and specified user target display mode.

[0041] In the all-user target display mode, the system resource publishing module displays a public idle window.

[0042] In the designated user target display mode, the system resource publishing module displays the public idle window and the directional idle window of the designated user target.

[0043] The idle window includes the following display elements in the form of a table publication: communication satellite, resource type, type of idle window, applicable user objectives and start and end periods of the idle window.

[0044] Based on the above content, it can be seen that in the form of graphic publishing, the user center can require the idle windows to be displayed in two modes: "all user targets" or "specified user targets" (that is, specific user targets). In the "all user targets" mode, the idle windows only include public idle windows, which refer to unoccupied time windows. In addition, in order to further reduce the blindness of resource application, if none of the user targets under the jurisdiction of user center A have the right to use beam X, the system resource publishing module will not display the resources of beam X for user center A.

[0045] In the "specified user target" mode, the idle window includes not only the public idle window but also the directional idle window of the selected designated target. The directional idle window refers to the time window that has been occupied by other user target plans, and within the time window occupied by the plan, the communication satellite resources can cover the designated user target. In other words, in the process of using a certain communication satellite resource to complete the task of other user targets, the communication satellite resources can also be used to complete the task of the designated user target. Similarly, in order to reduce the blindness of resource application, if the selected designated user target B does not have the right to use beam X, the system resource publishing module will not display the resources of beam X for the user center.

[0046] Figure 2 A schematic diagram of an idle window in a graphical publishing form provided by an embodiment of the present invention, optionally, the resource management system is set to display the idle windows from the current time to next Sunday by default after midnight on Thursday; the idle windows from the current time to this Sunday are displayed by default at other times. The system operator can specify a time period for display, and the start and end time and summary (user target, internal occupancy) of the corresponding time period can be displayed by clicking the corresponding position on the page with the mouse.

[0047] In an embodiment of the present invention, in the form of table publication, the display elements of the idle window include: communication satellite (specifically, communication satellite identifier), resource type (specifically, beam identifier), type of idle window (public idle window / directional idle window), applicable user targets (public idle window displays all user targets, directional idle window displays specified user targets) and start and end time periods of the idle window.

[0048] The user center can select the idle window type, start and end time period, communication satellite, resource type, and user target to query the idle window. Under the system default state, all public idle windows that have been sent from the current moment are displayed.

[0049] In an optional implementation, the legitimacy check of the communication satellite resource use application includes: a semantic check and a window visibility check.

[0050] After it is determined that the frame format and interface format of the application for use of the communication satellite resources meet the preset requirements, it is determined that the semantic check has passed.

[0051] When the user target that plans to occupy the communication satellite resources is located within the beam coverage of the communication satellite resources that it plans to occupy during the planned occupation period in the communication satellite resource use application, it is determined that the window visibility check has passed.

[0052] In actual application scenarios, after the user center successfully applies for communication satellite resources, the task may no longer be executed due to changes in the task plan. Therefore, the communication satellite resources in the original application are no longer needed during the planned occupation period in the original application. Therefore, in order to avoid waste of resources, in an optional implementation, the application information management module is also used to receive an application for cancellation of the use of communication satellite resources submitted by the user center through a designated website, and to perform a legality check on the application for cancellation of the use of communication satellite resources, so as to send the legal application for cancellation of the use of communication satellite resources to the resource allocation and planning management module.

[0053] The resource allocation and planning management module is used to process the legal application for revoking the use of communication satellite resources based on preset revocation rules, obtain a second processing result, and feed back the second processing result to the user center; wherein the second processing result includes: revocation success, revocation failure.

[0054] Optionally, the legality check of revoking the application for using the communication satellite resources includes: a semantic check and a legality check of the submission time.

[0055] After it is determined that the frame format and interface format of the application for revocation of the use of communication satellite resources meet the preset requirements, it is determined that the semantic check has passed.

[0056] When it is determined that the time difference between the submission time of the communication satellite resource use application to be revoked and the task start time in the communication satellite resource use application to be revoked is greater than or equal to a preset time threshold, it is determined that the legality check of the submission time has passed.

[0057] It should be noted that the prerequisite for executing the legality check of the submission time is that the communication satellite resource use application pointed to by the communication satellite resource use application cancellation (that is, the communication satellite resource use application to be revoked) exists. If the application does not exist, it can be directly determined that the legality check of the communication satellite resource use application cancellation fails. If it is determined that the application is an illegal application, the application information management module will prompt the user center in the form of a pop-up dialog box to indicate the reason why the application is illegal. If it is determined that the application is a legal application, the application information management module needs to send it to the resource allocation and planning management module, and then wait for the processing result of the resource allocation and planning management module through polling.

[0058] After receiving the legitimate application for canceling the use of communication satellite resources, the resource allocation and planning management module will process the legitimate application for canceling the use of communication satellite resources according to the preset cancellation rule, obtain a second processing result and feed it back to the user center. The embodiment of the present invention does not specifically limit the content of the preset cancellation rule, and the user can set it according to actual needs. For example, the cancellation can be confirmed to be legitimate, or the cancellation number of the user center in the historical time period is less than the preset number threshold, then the cancellation is allowed.

[0059] After obtaining the second processing result, the application page of the user center will be updated accordingly. Optionally, the second processing result will be displayed on the interactive interface of the designated website, and the idle window release page and the communication satellite resource usage plan page of the system resource release module will be updated as appropriate. Specifically, if the second processing result is a successful revocation, the idle window release page and the communication satellite resource usage plan page will be updated according to the application information in the currently revoked communication satellite resource usage application; if the second processing result is a failed revocation, there is no need to update the above two pages.

[0060] In addition, for legitimate applications to revoke the use of communication satellite resources, the application information management module is also used to save the information of the revocation application as a file that meets the interface requirements, store the file in the website file table of the website database, and store the file number in the notification message table in the website database to provide log records for subsequent information tracing.

[0061] Furthermore, after the user center successfully applies for communication satellite resources, the mission information (for example, time, swing angle, mission nature, link rate, etc.) of the original communication satellite resource usage plan may change. Therefore, in an optional implementation, the application information management module is also used to receive the resource usage plan adjustment application submitted by the user center through the designated website, and perform a legitimacy check on the resource usage plan adjustment application to send the legitimate resource usage plan adjustment application to the resource allocation and plan management module.

[0062] The resource allocation and plan management module is used to process legitimate resource usage plan adjustment applications based on preset conflict resolution rules, obtain a third processing result, and feed the third processing result back to the user center; wherein the third processing result includes: adjustment successful, adjustment failed.

[0063] After receiving the resource use plan adjustment application sent by the user center, the application information management module first performs a legality check on the application. The legality check items include at least: semantic check and window visibility check. It should be noted that the prerequisite for performing the window visibility check is that the communication satellite resource use application pointed to by the resource use plan adjustment application (that is, the communication satellite resource use application to be adjusted) exists. If the application does not exist, it can be directly determined that the legality check of the resource use plan adjustment application has failed. If it is determined that the application is an illegal application, the application information management module will prompt the user center in the form of a pop-up dialog box to indicate the reason why the application is illegal. If it is determined that the application is a legal application, the application information management module needs to send it to the resource allocation and planning management module, and then wait for the processing result of the resource allocation and planning management module through polling.

[0064] After receiving a legitimate resource usage plan adjustment application, the resource allocation and plan management module will process the legitimate resource usage plan adjustment application according to a preset conflict resolution rule, obtain a third processing result and feed it back to the user center.

[0065] After obtaining the third processing result, the plan page of the user center will be updated accordingly. Optionally, the third processing result will be displayed on the interactive interface of the designated website, and the idle window release page and the communication satellite resource usage plan page of the system resource release module will be updated as appropriate. Specifically, if the third processing result is a successful adjustment, the idle window release page and the communication satellite resource usage plan page will be updated according to the application information in the resource usage plan adjustment application; if the third processing result is a failed adjustment, there is no need to update the above two pages.

[0066] In addition, for legitimate resource usage plan adjustment applications, the application information management module is also used to save the application information as a file that meets the interface requirements, store the file in the website file table of the website database, and store the file number in the notification message table in the website database to provide log records for subsequent information tracing.

[0067] In an optional implementation, the application information such as the communication satellite resource use application, the communication satellite resource use cancellation application and the resource use plan adjustment application of the user center can be submitted by directly uploading the generated application file, and can be uploaded in batches. The communication satellite resource use application can also be submitted after entering it one by one from the web page.

[0068] The application for canceling the use of communication satellite resources can be submitted from the application page. The user center can directly cancel a communication satellite resource use application with one click. The application for adjusting the resource use plan can be submitted from the plan page. Specifically, the user center can adjust or supplement the corresponding information (including time, roll angle, mission nature, link rate, etc.) based on an existing resource use plan, thereby generating an application for adjusting the resource use plan.

[0069] Optionally, the user center can query its own application information according to the start and end time, user goal, mission type and other conditions, including the specific content of the application, the resource allocation status of the application and the detailed resource allocation processing results, etc. The general user center can only view its own application, and the special user center can view the applications of all satellites under its jurisdiction.

[0070] In an optional implementation, the resource management system further includes: a planning information management module.

[0071] The plan information management module is used to receive plan query requests submitted by the user center through the designated website, and feedback the query results based on the query authority of the user center.

[0072] Among them, the user center includes the following categories: ordinary user center and special user center; the ordinary user center only has the query authority for its own mission plan; the special user center has the query authority for the mission plans of all satellites under its jurisdiction.

[0073] Specifically, the user center can query the planning information of the user targets under its jurisdiction according to the mission time, communication satellite resources, user targets and other conditions. The general user center can only view and download its own planning information, while the special user center can view and download the planning information of all satellites under its jurisdiction. In addition, planning information such as user plans and cancellation plans can be downloaded and saved as corresponding files on the website, and batch download is supported.

[0074] In an optional implementation, the resource management system further includes: a user target information management module and a user center information management module.

[0075] The user target information management module is used to receive and store the movement information of the user targets under its jurisdiction sent by the user center.

[0076] The user center information management module is used to receive and process user center addition requests, deletion requests and modification requests sent by system maintenance personnel.

[0077] Specifically, the user center can submit the motion information of the user target under its jurisdiction by uploading the generated file directly from the web page, such as the number of user spacecraft's post-precision orbits, user target attitude changes, user target's scheduled track, theoretical trajectory, user target motion area, etc. After the user center uploads the above file, the website stores the file in the website file table of the website database and stores the file number in the notification message table in the website database. After the website is synchronized to the internal database, it will be processed by the resource allocation and planning management module, including operations such as storage, parameter configuration and information synchronization.

[0078] System maintenance personnel can also add, delete and modify user center information by sending new addition requests, deletion requests and modification requests to the user center, including: the name of the user center, IP address, user address code, user targets, and other important information of the user center.

[0079] In an optional implementation, the resource management system further includes: a security management module.

[0080] The security management module is used to maintain the access security of the resource management system based on preset defense strategies, and is also used to record the operation logs of all user centers.

[0081] Specifically, the preset defense strategy requires:

[0082] 1. The designated website of the resource management system is only open to the user center that has been reviewed and authorized. The identity of the user center is verified by combining the randomly generated image format verification code information. When the identity is authenticated in the user center, the identity information of the user center is encrypted and transmitted.

[0083] 2. For user center requests to query application plan information, technical measures shall be taken to prevent illegal intrusion into the database.

[0084] 3. Control suspected password cracking behavior in the user center. When the user center fails to enter the password multiple times, the user center will be prohibited from logging in.

[0085] 4.
