Description

Technical Field

[0001] The present application relates to the field of satellite communication, navigation and remote sensing technology, and in particular to a multi-level collaborative linkage method and system for ocean satellite communication, navigation and remote sensing. Background Art

[0002] With the rapid development of satellite Internet technology, high-precision navigation technology, and high-resolution remote sensing technology, the comprehensive application of satellite communication, navigation, and remote sensing (communication, navigation, and remote sensing) is widely used in the ocean, emergency and other industries, which has promoted the rapid development of various industries towards digitalization and intelligence. At present, the comprehensive application of communication, navigation, and remote sensing is mainly reflected in two directions. The first is the spatial integration of space-based resources. It carries communication, navigation, and remote sensing payloads on the same satellite platform at the same time to realize the integration of single-satellite communication, navigation, and remote sensing functions, or coordinates various types of communication, navigation, and remote sensing satellites to form a constellation system with space communication, navigation, and remote sensing integration functions. This space-based resource integration model is currently in the development stage and has not yet been promoted and applied in industry applications; the second is the comprehensive application of satellite communication, navigation, and remote sensing resources on the ground (including land and ocean), which is mainly the independent construction of satellite communication, navigation, and remote sensing application systems in various industries, and each system obtains information and processes it separately before comprehensive application. In the context of the rapid development of satellite communication, navigation, and remote sensing technology, how to give full play to the systematic and systematic service capabilities of satellite communication, navigation, and remote sensing ground comprehensive applications in the business systems of various industries on the ground is an important driving force for improving the information service capabilities of industry business applications, and is also an important technical development demand for the future comprehensive application of satellite communication, navigation, and remote sensing. Therefore, it is necessary to comprehensively enhance the satellite communication, navigation, and remote sensing ground comprehensive application service capabilities.

[0003] The existing ground-based integrated application of satellite communication, navigation and remote sensing obtains information through satellite communication, navigation and remote sensing systems respectively, and then realizes the integrated application of processed information after processing it separately on their respective business application platforms. The existing ground-based integrated application of satellite communication, navigation and remote sensing has not realized multi-level and systematic integration, and is mainly reflected in the integrated application at a certain point or a certain level. Its integrated application effect is not high, its problem-solving ability is not strong, and its benefits are not high. It mainly reflects the shortcomings in three aspects: First, at the marine monitoring site, there is no coordinated and integrated application of multiple means of satellite communication, navigation and remote sensing, resulting in incomplete monitoring data types and insufficient accuracy; second, the satellite communication, navigation and remote sensing application systems are independently constructed, and satellite communication resources, satellite remote sensing resources and satellite navigation resources are not dispatched on demand in real time, resulting in waste of satellite resources and lack of real-time coordinated use capabilities, and insufficient real-time service capabilities for business; third, the business system's integrated integrated dispatching capabilities for communication, navigation and remote sensing satellite resources are insufficient, resulting in weak rapid linkage capabilities between marine scene on-site monitoring, business system warning and emergency handling / management and disposal activities, and weak emergency rapid response / management and disposal capabilities.

[0004] Therefore, there is an urgent need for a multi-level coordinated linkage method for ocean satellite communication, navigation and remote sensing, which can realize on-demand and instant comprehensive scheduling of various satellite resources based on the mutual cooperation of multiple levels, form the ability to deeply integrate multi-source data, ensure the rapid linkage of multiple businesses, and enhance the comprehensive ground application capabilities of satellite communication, navigation and remote sensing. Summary of the invention

[0005] In view of this, the present application provides a method and system for multi-level coordinated linkage of ocean satellite communication, navigation and remote control, which has the comprehensive perception capability of various means of satellite communication, navigation and remote control, realizes on-demand and instant comprehensive scheduling of various satellite resources, forms the ability of deep fusion of multi-source data, ensures the rapid linkage of multiple businesses, and enhances the comprehensive ground application capability of satellite communication, navigation and remote control.

[0006] Specifically, the present application is implemented through the following technical solutions:

[0007] The first aspect of the present application provides a multi-level coordinated linkage method for ocean satellite communication, navigation and remote sensing, the method comprising:

[0008] The business application system generates business requirements, and based on the business requirements, instantly sends the communication, navigation and remote sensing satellite resource requirements to the communication, navigation and remote sensing satellite resource scheduling system and the data processing system; the communication, navigation and remote sensing satellite resource scheduling system and the data processing system include multiple service platforms, each service platform corresponds to a type of satellite resources;

[0009] The communication, navigation and remote sensing satellite resource scheduling system and data processing system instantly call the corresponding target satellite resources from the operator's communication, navigation and remote sensing satellite resource system according to the communication, navigation and remote sensing satellite resource demand, and transmit the monitoring data monitored by the operation monitoring system and management activities to the communication, navigation and remote sensing satellite resource scheduling system and data processing system based on the target satellite resources;

[0010] The monitoring data is obtained by comprehensively applying multiple monitoring methods such as satellite communication, navigation and remote sensing. The order and combination relationship of the monitoring methods are different in different application scenarios. The target satellite resources include communication satellite resources, navigation satellite resources and remote sensing satellite resources. The source, type and time period of the monitoring data transmitted by each type of satellite resources are different.

[0011] The communication, navigation and remote sensing satellite resource scheduling system and the data processing system fuse the monitoring data received from each target satellite resource to obtain fused information, and transmit the fused information to the business application system;

[0012] The business application system instantly controls the management activities corresponding to the business needs based on the fusion information.

[0013] The second aspect of the present application provides a multi-level coordinated linkage system for ocean satellite communication, navigation and remote sensing, characterized in that the system includes an operation monitoring system and management activities, an operator communication, navigation and remote sensing satellite resource system, a communication, navigation and remote sensing satellite resource scheduling system and data processing system, and a business application system;

[0014] The operation monitoring system and management activities are used to monitor the data of the target ocean area, obtain the monitoring data, and transmit the monitoring data to the shore-sea-air-space multi-source remote sensing large model through the target satellite resources in the operator's communication and remote sensing satellite resource system;

[0015] The business application system is used to generate business needs, and based on the business needs, it instantly sends the communication, navigation and remote sensing satellite resource needs to the communication, navigation and remote sensing satellite resource scheduling system and data processing system; the communication, navigation and remote sensing satellite resource scheduling system and data processing system include multiple service platforms, each service platform corresponds to a type of satellite resources;

[0016] The communication, navigation and remote sensing satellite resource scheduling system and data processing system are used to instantly call corresponding target satellite resources from the operator's communication, navigation and remote sensing satellite resource system based on the communication, navigation and remote sensing satellite resource demand; the target satellite resources include communication satellite resources, navigation satellite resources and remote sensing satellite resources, and the source, type and time period of the monitoring data transmitted by each type of satellite resources are different;

[0017] The operator's communication, navigation and remote sensing satellite resource system is used to provide the communication, navigation and remote sensing satellite resource scheduling system and data processing system with the monitoring data monitored by the operation monitoring system and management activities based on the target satellite resources;

[0018] The communication, navigation and remote sensing satellite resource scheduling system and data processing system are also used to fuse the monitoring data received from each target satellite resource to obtain fused information, and transmit the fused information to the business application system;

[0019] The business application system is also used to instantly control management activities corresponding to the business needs based on the fusion information.

[0020] The present application provides a method and system for the multi-level coordinated linkage of ocean satellite communication, navigation and remote sensing. In the first aspect, the present application is a method for coordinated linkage at multiple levels, and the multiple levels include business application systems, communication, navigation and remote sensing satellite resource scheduling systems and data processing systems, operator communication, navigation and remote sensing satellite resource systems, and operation monitoring systems and management activities. Among them, in the operation monitoring system and management activity layer, monitoring data of multiple different data types are obtained through multiple monitoring means, and multi-means comprehensive monitoring is realized. In the communication, navigation and remote sensing satellite resource scheduling system and data processing system layer, by calling the corresponding target satellite resources on demand and in real time according to the business needs of the business application system to obtain monitoring data, resource on-demand coordinated scheduling is realized. In the communication, navigation and remote sensing satellite resource scheduling system and data processing system layer, monitoring data of multiple different data types are ultimately sent to the shore, sea, air and space multi-source remote sensing large model of this layer, and the shore, sea, air and space multi-source remote sensing large model performs fusion processing on the received monitoring data, realizing multi-source data fusion. In the business application system layer, by using the fusion information sent based on the shore, sea, air and space multi-source remote sensing large model, the management activities corresponding to the business needs are immediately controlled, and rapid business coordinated linkage is realized. Through the comprehensive application of operation monitoring systems and management activities, operator communication, navigation, remote sensing satellite resource systems, communication, navigation, remote sensing satellite resource scheduling systems and data processing systems, and business application systems, a multi-level, systematic communication, navigation, remote sensing integrated application service is achieved, from multi-means comprehensive monitoring, on-demand coordinated scheduling of resources, multi-source data fusion to rapid business coordination and linkage. This solves the problem of weak rapid linkage capabilities between multiple business processes in traditional methods, improves the rapid emergency response capabilities of disasters and the efficient execution capabilities of management and guidance activities, can reduce property losses in the first place, and improves the efficient and safe operation management capabilities of the marine industry.

[0021] Secondly, the satellite resource scheduling system and data processing system for communication, navigation and remote sensing determine the target satellite resources for transmitting monitoring data and the calling method of the target satellite resources based on the business needs of the business application system, and call the target satellite resources based on the calling method to realize the reuse of the satellite resource systems of each operator and the unified on-demand scheduling of the satellite resources of the operator, so as to promote the efficient and immediate application of satellite resources by various businesses, and solve the problem of low resource utilization efficiency and high system construction and use costs caused by the traditional method of building various satellite ground systems or independently scheduling various satellite resources. At the same time, it also solves the problem of insufficient business real-time service capabilities caused by insufficient resource integration and coordinated scheduling capabilities of the traditional method. Specifically, this system has the ability to collect various monitoring information using the Beidou satellites, remote sensing satellites, communication satellites and ground system resources of the operator. The system's calling of the operator's satellite resources directly depends on the needs of the business layer, that is, if the business layer needs it, it directly calls mature commercial satellites to obtain the corresponding information, otherwise it does not call it. In this way, the coordinated use of various satellite resources broadens the source of system information and improves the accuracy of system decision-making. At the same time, because satellite resources are called on demand, there is no need to build various satellites and corresponding satellite ground systems separately, which saves the cost of using the system.

[0022] On the third aspect, the large multi-source remote sensing model of shore, sea, air and space in the present application integrates and processes the different types of original monitoring data received based on various types of communication, navigation and remote sensing satellites. Compared with the traditional method of first processing each type of communication, navigation and remote sensing monitoring data separately and then integrating them, it better ensures the synchronization and correlation between various types of data, improves the degree of data fusion, improves the efficiency of data processing, improves the ability to extract intelligent information from various types of monitoring data, and enhances the scientific nature of subsequent control and management activities based on the monitoring data.

[0023] In the fourth aspect, the multiple operation monitoring systems proposed in this application make comprehensive use of multiple satellite communication, navigation and remote control means to obtain different monitoring data of the target ocean area. When obtaining monitoring data in different application scenarios, the order and combination relationship of various satellite communication, navigation and remote control means are different. When obtaining the monitoring data corresponding to marine disasters, the first monitoring data is first obtained by navigation means, and then the second monitoring data is obtained by remote sensing means, and finally the third monitoring data is obtained by communication means. When obtaining the monitoring data corresponding to marine engineering operations, the first monitoring data is obtained by navigation means, and the second monitoring data is obtained by remote sensing means at the same time, and the first monitoring data is transmitted by communication means, that is, the acquisition and transmission of the first monitoring data use navigation means and communication means at the same time. When obtaining the monitoring data corresponding to reclamation, the second monitoring data is first obtained by remote sensing means; then the first monitoring data is obtained by navigation means, and the first monitoring data is transmitted by communication means, and the third monitoring data is obtained by communication means at the same time. In this way, the reliability, accuracy, and real-time performance of the collected data such as marine disaster monitoring, marine engineering operation monitoring, and reclamation illegal construction monitoring are improved, the monitoring data type is enriched, and the monitoring scope is expanded.

[0029] Specific embodiments are given below to introduce the technical solution of the present application in detail.

[0030] Figure 1 This is a flow chart of the first embodiment of the multi-level collaborative linkage method for ocean satellite communication, navigation and remote sensing provided by this application. Please refer to Figure 1 , the method provided in this embodiment may include:

[0031] S101. The business application system generates business needs, and based on the business needs, instantly sends the communication, navigation, and remote sensing satellite resource needs to the communication, navigation, and remote sensing satellite resource scheduling system and data processing system; the communication, navigation, and remote sensing satellite resource scheduling system and data processing system include multiple service platforms, and each service platform corresponds to a type of satellite resources.

[0032] Specifically, the method provided in this embodiment is applied to a multi-level coordinated linkage system of ocean satellite communication, navigation and remote sensing, which includes an operation monitoring system and management activities, an operator communication, navigation and remote sensing satellite resource system, a communication, navigation and remote sensing satellite resource scheduling system and data processing system, and a business application system. Among them, the communication, navigation and remote sensing satellite resource scheduling system and data processing system include a communication, navigation and remote sensing resource service integrated scheduling platform, multiple service platforms and a shore-sea-air-space multi-source remote sensing large model, and the multiple service platforms include a communication satellite integrated network management platform, a Beidou service platform and a remote sensing resource service platform.

[0033] Furthermore, the business requirements of the business application system are determined by the application scenario. The demand for communication, navigation, and remote sensing satellite resources is related to the business requirements of the business application system. The demand for communication, navigation, and remote sensing satellite resources includes multiple types of satellite resource requirements. For example, the demand for communication, navigation, and remote sensing satellite resources may include communication satellite resource requirements, navigation satellite resource requirements, and remote sensing satellite resource requirements. Combined with the above description, the communication, navigation, and remote sensing satellite resource scheduling system and data processing system include multiple service platforms, each service platform corresponds to a type of satellite resources, that is, the communication satellite integrated network management platform corresponds to communication satellite resources, the Beidou service platform corresponds to navigation satellite resources, and the remote sensing resource service platform corresponds to remote sensing satellite resources.

[0034] The method provided in this embodiment, when receiving the business needs of the business application system, the operator's communication, navigation and remote sensing resource system can immediately call the target satellite resources corresponding to the business needs according to the business needs to obtain the monitoring data corresponding to the business needs, without the need to build a communication, navigation and remote sensing satellite ground application system. It has the advantages of low investment cost and high economic benefit, and solves the problems of low resource utilization efficiency and high system construction and use costs caused by the traditional method of separately building various communication, navigation and remote sensing satellite ground application systems or independently scheduling various satellite resources. The response time is fast, no waste of resources will be caused, and the real-time service capability is strong.

[0035] S102. The communication, navigation and remote sensing satellite resource scheduling system and the data processing system instantly call the corresponding target satellite resources from the operator's communication, navigation and remote sensing satellite resource system according to the communication, navigation and remote sensing satellite resource demand, and transmit the monitoring data monitored by the operation monitoring system and management activities to the communication, navigation and remote sensing satellite resource scheduling system and the data processing system based on the target satellite resources.

[0036] Specifically, the monitoring data is obtained by the operation monitoring system and management activities through monitoring the target ocean area, wherein the target ocean area is set according to actual needs, and it usually corresponds to the operation monitoring system and management activities. It should be noted that the specific composition of the monitoring data is related to the business requirements of the business application system, that is, the business requirements of the business application system are different, the corresponding operation monitoring system and management activities are also different, and the specific composition of the monitoring data is also different.

[0037] Furthermore, the monitoring data can be divided into the first monitoring data, the second monitoring data and the third monitoring data according to the source, type and time period. Among them, the first monitoring data is transmitted by navigation satellite resources or by the integration of navigation satellite resources and communication satellite resources, the second monitoring data is transmitted by remote sensing satellite resources, and the third monitoring data is transmitted by communication satellite resources. It should be noted that communication satellite resources and remote sensing satellite resources include multiple different satellite systems respectively, and the data transmitted by different satellite systems in the same satellite resource are different (the corresponding target satellite resources and the target satellite system of the target satellite resources are selected based on the business needs of the business application system). For example, the monitoring data (third monitoring data) obtained by the communication satellite resources include video data, positioning information, and forensic return data; remote sensing satellite resources obtain satellite remote sensing data (second monitoring data) of multiple remote sensing satellite systems according to the business needs and transit time of the business application system; navigation satellite resources include the Beidou navigation satellite system, and the Beidou navigation satellite system obtains monitoring data (first monitoring data) corresponding to the business needs of the business application system, and the monitoring data obtained by the Beidou navigation satellite system includes positioning information and conventional meteorological and hydrological information based on short message transmission.

[0038] Furthermore, in addition to monitoring data, the data monitored by the operation monitoring system and management activities also include control and management activity data, which is transmitted by communication satellite resources. The control and management activity data includes satellite phone, voice and video data.

[0039] It should be noted that the business requirements of the business application system are different, and the corresponding monitoring data are also different. When the business requirements of the business application system are marine disaster monitoring, the corresponding monitoring data include first monitoring data, second monitoring data and third monitoring data, and also include control and management activity data. Among them, the first monitoring data includes conventional meteorological and hydrological information based on short message transmission, which is transmitted through Beidou short messages in navigation satellite resources. The second monitoring data includes satellite remote sensing data (ocean satellite remote sensing data and meteorological satellite remote sensing data), which is transmitted through remote sensing satellite resources (ocean remote sensing satellites and meteorological remote sensing satellites). The third monitoring data includes video data, which is transmitted through high-throughput satellites in communication satellite resources. Control and management activity data includes satellite phones, which are transmitted through Tiantong satellites in communication satellite resources.

[0040] When the business demand of the business application system is marine engineering operation monitoring, the corresponding monitoring data includes first monitoring data and second monitoring data, and also includes control and management activity data. The first monitoring data includes positioning information, which is obtained through Beidou satellites in navigation satellite resources and then transmitted by high-throughput satellites in communication satellite resources. The second monitoring data includes satellite remote sensing data (SAR satellite remote sensing data), which is transmitted through remote sensing satellite resources (SAR remote sensing satellites). Control and management activity data includes voice and video data, which is transmitted through high-throughput satellites in communication satellite resources.

[0041] When the business demand of the business application system is land reclamation monitoring, the corresponding monitoring data includes first monitoring data, second monitoring data and third monitoring data, and also includes control and management activity data. The first monitoring data includes positioning information, which is obtained through the Beidou satellite in the navigation satellite resources and then transmitted by the high-throughput satellite in the communication satellite resources. The second monitoring data includes satellite remote sensing data (high-resolution remote sensing data), which is transmitted through remote sensing satellite resources (high-resolution remote sensing satellite). The third monitoring data includes forensic return data, which is transmitted through the high-throughput satellite in the communication satellite resources. The control and management activity data includes voice and video data, which is transmitted through the high-throughput satellite in the communication satellite resources.

[0042] Further, in combination with the above description, the communication, navigation and remote sensing satellite resource scheduling system and the communication, navigation and remote sensing resource integrated scheduling platform in the data processing system are used to call the communication satellite integrated network management platform of the operator's communication satellite system, the Beidou service platform for calling the Beidou navigation satellite system, and the remote sensing resource service platform for calling the operator's remote sensing satellite system. Among them, the communication, navigation and remote sensing resource integrated scheduling platform transmits the communication, navigation and remote sensing satellite resource demand to the corresponding target service platform based on the communication, navigation and remote sensing satellite resource demand, and the target service platform instantly calls the target satellite resources to the corresponding operator's communication, navigation and remote sensing satellite resource system based on the communication, navigation and remote sensing satellite resource demand.

[0043] For example, when the target service platform is a communication satellite integrated network management platform, the corresponding operator's communication satellite resource system is the operator's communication satellite system, and the corresponding target satellite resources are communication satellite resources. At this time, the communication satellite integrated network management platform applies to the operator's communication satellite system for calling communication satellite resources.

[0044] When the target service platform is the Beidou service platform, the corresponding operator's communication, navigation and remote sensing satellite resource system is the Beidou navigation satellite system, and the corresponding target satellite resources are navigation satellite resources. At this time, the Beidou service platform applies to the Beidou navigation satellite system for calling navigation satellite resources.

[0045] When the target service platform is a remote sensing resource service platform, the corresponding operator's communication and navigation satellite resource system is the operator's remote sensing satellite system, and the corresponding target satellite resources are remote sensing satellite resources. At this time, the remote sensing resource service platform applies to the operator's remote sensing satellite system for calling remote sensing satellite resources.

[0046] In specific implementation, the communication, navigation, and remote sensing satellite resource scheduling system and data processing system instantly call the target satellite resources from the operator's communication, navigation, and remote sensing satellite resource system according to the communication, navigation, and remote sensing satellite resource demand, including: the communication, navigation, and remote sensing resource comprehensive scheduling platform determines the target monitoring information, target satellite resources and calling method according to the communication, navigation, and remote sensing satellite resource demand; determines the corresponding calling platform according to the target satellite resources; calls the calling platform according to the calling method, and uses the satellite system corresponding to the calling platform to receive the target monitoring information.

[0047] Specifically, the target satellite resources represent the satellite resources used to transmit monitoring data, which are determined by the communication, navigation, and remote sensing satellite resource requirements. Different communication, navigation, and remote sensing satellite resource requirements correspond to different target satellite resources. Furthermore, the calling platform is determined based on the target satellite resources, and each type of target satellite resource corresponds to a calling platform. The calling method represents the way in which the platform is called. The calling method is related to the communication, navigation, and remote sensing satellite resource requirements. Different communication, navigation, and remote sensing satellite resource requirements correspond to different calling methods.

[0048] In specific implementation, the communication, navigation, and remote sensing resource integrated dispatching platform determines the corresponding target satellite resources for transmitting target monitoring information, the target monitoring information to be transmitted, and the calling method for calling the target satellite resources based on the received communication, navigation, and remote sensing satellite resource requirements. Further, based on the determined target satellite resources, the corresponding calling platform and the satellite system corresponding to the calling platform are determined (different satellite systems transmit different data), the platform is called based on the determined calling method, and the target monitoring information is received based on the satellite system corresponding to the calling platform.

[0049] Optionally, the comprehensive scheduling platform for communications, navigation, and remote sensing resources determines the target monitoring information, target satellite resources, and calling method according to the communications, navigation, and remote sensing satellite resource requirements, including: determining the calling order according to the communications, navigation, and remote sensing satellite resource requirements, and determining the calling time based on the target satellite resources and the communications, navigation, and remote sensing satellite resource requirements.

[0050] Specifically, the calling mode includes the calling time and the calling sequence, and the calling time represents the calling time of the target satellite resource. When the target satellite resource is a plurality of different satellite resources, the calling sequence represents the calling sequence of different target satellite resources. It should be noted that the business requirements of the business application system are different, and the requirements for communication, navigation and remote sensing satellite resources are also different. Accordingly, the calling time and calling sequence of the target satellite resources are also different.

[0051] Optionally, in combination with the above description, the target satellite resources include communication satellite resources, navigation satellite resources and remote sensing satellite resources. Among them, remote sensing satellite resources include ocean remote sensing satellite resources, meteorological remote sensing satellite resources, SAR remote sensing satellite resources and high-resolution remote sensing satellite resources. When the target satellite resources are remote sensing satellite resources, the method includes: responding to the business needs, determining the target remote sensing satellite resources according to the business needs; determining the target satellite system in the target remote sensing satellite resources according to the monitoring objects corresponding to the business needs, the monitoring objects of different business needs are different, and the target satellite systems of different monitoring objects are different.

[0052] Specifically, the business requirements of the business application system are different, and the corresponding monitoring objects are also different. Accordingly, the remote sensing satellite resources used to transmit the monitoring data of the related monitoring objects are also different. Among them, the remote sensing satellite resources include multiple satellite systems, and each satellite system transmits different data based on the different monitoring objects, that is, the business requirements of the business application system are different, and the satellite systems of the remote sensing satellite resources are also different. In summary, when the target satellite resources corresponding to the business requirements of the business application system are remote sensing satellite resources, the business requirements determine the corresponding remote sensing satellite resources and the satellite systems of the remote sensing satellite resources.

[0053] In specific implementation, based on the business requirements of the business application system, the target remote sensing satellite resources corresponding to the business requirements are determined. Based on the monitoring objects corresponding to the business requirements of the business application system, the target satellite system for receiving the monitoring data of the monitoring objects in the target remote sensing satellite resources is determined.

[0054] In the method provided in this embodiment, multiple operation monitoring systems comprehensively utilize multiple satellite communication, navigation and remote control means to obtain different monitoring data of the target ocean area. When obtaining monitoring data in different application scenarios, the order and combination relationship of various satellite communication, navigation and remote control means are different. When obtaining monitoring data corresponding to marine disasters, first use navigation means to obtain the first monitoring data, then use remote sensing means to obtain the second monitoring data, and finally use communication means to obtain the third monitoring data. When obtaining monitoring data corresponding to marine engineering operations, use navigation means to obtain the first monitoring data, and use remote sensing means to obtain the second monitoring data at the same time, and use communication means to transmit the first monitoring data, that is, the acquisition and transmission of the first monitoring data use navigation means and communication means at the same time. When obtaining monitoring data corresponding to reclamation, first use remote sensing means to obtain the second monitoring data; then use navigation means to obtain the first monitoring data, and use communication means to transmit the first monitoring data, and use communication means to obtain the third monitoring data at the same time. In this way, the reliability, accuracy, and real-time performance of the collected data such as marine disaster monitoring, marine engineering operation monitoring, and reclamation illegal construction monitoring are improved, the monitoring data type is enriched, and the monitoring scope is expanded.

[0055] S103, the communication, navigation and remote sensing satellite resource scheduling system and the data processing system fuse the monitoring data received from each target satellite resource to obtain fused information, and transmit the fused information to the business application system.

[0056] Specifically, the communication, navigation, and remote sensing satellite resource scheduling system and data processing system include a communication, navigation, and remote sensing resource service platform and a shore, sea, air, and space multi-source remote sensing large model. The communication, navigation, and remote sensing resource service platform is used to call target satellite resources to obtain monitoring data, and the shore, sea, air, and space multi-source remote sensing large model is used to fuse and process the monitoring data.

[0057] In specific implementation, the communication, navigation, and remote sensing satellite resource scheduling system and data processing system fuse the monitoring data received from each target satellite resource to obtain fusion information, and transmit the fusion information to the business application system, including: the communication, navigation, and remote sensing resource service platform instantly calls multiple target satellite resources according to the business needs, the shore, sea, air, and space multi-source remote sensing large model receives the monitoring data containing multiple different types of data and performs fusion processing, and sends the fused information to the business application system; the business application system sends the communication, navigation, and remote sensing satellite resource needs to the communication, navigation, and remote sensing resource service platform based on the fusion information and the warning conditions corresponding to the business needs, so as to control the management activities corresponding to the business needs.

[0058] Specifically, in combination with the above description, the monitoring data includes at least first monitoring data, second monitoring data and third monitoring data. The first monitoring data, the second monitoring data and the third monitoring data are of different types, and each target satellite resource transmits monitoring data of one type of data.

[0059] In specific implementation, the communication, navigation and remote sensing resource service platform determines multiple target satellite resources according to the business needs of the business application system, calls each target satellite resource in turn based on the calling method of the multiple target satellite resources, and transmits the different types of monitoring data corresponding to each target satellite resource to the shore, sea, air and space multi-source remote sensing large model. The shore, sea, air and space multi-source remote sensing large model fuses the received monitoring data containing multiple different types, and sends the fused information to the business application system. The business application system determines the corresponding early warning conditions based on the business needs, determines whether the fused information meets the early warning conditions, and selects the corresponding processing method based on the judgment result (when the fused information meets the early warning conditions, control the management activities corresponding to the business needs; when the fused information does not meet the early warning conditions, repeat the judgment process).

[0060] Optionally, the communication, navigation, remote sensing resource service platform instantly calls multiple target satellite resources according to the business needs, the shore, sea, air, and space multi-source remote sensing large model receives monitoring data containing multiple different types of data and performs fusion processing, and sends the fused fusion information to the business application system, including: the shore, sea, air, and space multi-source remote sensing large model fuses the received monitoring data of multiple different types of data to obtain first fusion information, and transmits the first fusion information to the business application system; the business application system determines whether a supplementary call is needed based on the business needs, and when it is determined that a supplementary call is needed, compares the first fusion information with the verification conditions, and determines the supplementary call requirements for target satellite resources different from the first fusion information based on the comparison results, the communication, navigation, remote sensing resource service platform obtains supplementary information according to the supplementary call requirements and sends it to the shore, sea, air, and space multi-source remote sensing large model; the verification conditions are related to the business needs; the shore, sea, air, and space multi-source remote sensing large model fuses the first fusion information and the supplementary information to obtain fusion information.

[0061] Specifically, the business requirements of business application systems are different, and the corresponding monitoring data are also different. The way in which the shore, sea, air and space multi-source remote sensing large model fuses the monitoring data to obtain fused information is also different (when it is determined that no supplementary call is needed, the first fused information after fusion is directly determined as the fused information; when it is determined that a supplementary call is needed, the first fused information after fusion and the supplementary information obtained by the supplementary call are fused to obtain the fused information).

[0062] In specific implementation, the shore, sea, air and space multi-source remote sensing large model determines the monitoring data of multiple different types of data for fusion based on the business needs of the business application system, fuses to obtain the first fusion information, and transmits the first fusion information to the business application system. The business application system determines whether to make a supplementary call based on its own business needs. When it is determined that no supplementary call is required, the business application system controls the management activities corresponding to the business needs based on the received first fusion information and warning conditions. When it is determined that a supplementary call is required, the business application system compares the first fusion information with the verification conditions. When the first fusion information meets the verification conditions, it determines the supplementary call requirements of the target satellite resources different from the first fusion information, and then calls the target satellite resources to obtain supplementary information, and sends the supplementary information to the shore, sea, air and space multi-source remote sensing large model. Further, the shore, sea, air and space multi-source remote sensing large model fuses the first fusion information and the supplementary information to obtain fusion information. The business application system controls the management activities corresponding to the business needs based on the received fusion information and warning conditions.

[0063] The method provided in this embodiment, on the first aspect, after acquiring the corresponding type of monitoring data based on the target satellite resources, directly sends the monitoring data to the shore, sea, air and space multi-source remote sensing large model for fusion processing. Compared with the traditional method of first processing various types of original monitoring data by independent systems according to categories and then fusing them, which leads to problems such as insufficient fusion and weak information extraction ability, the present application directly fuses various types of original monitoring data, better ensures the synchronization and correlation between various types of data, improves the data fusion degree, improves the efficiency of data processing, enhances the intelligent information extraction ability of various types of monitoring data, and improves the scientific nature of the subsequent control and management activities based on the fusion results of various types of monitoring data.

[0064] S104: The business application system instantly controls management activities corresponding to the business needs based on the fusion information.

[0065] Specifically, management activities represent the management of the target ocean area, and management activities correspond to the business requirements of the business application system. Different business requirements lead to different corresponding management activities.

[0066] In specific implementation, after the business application system receives the fused information transmitted by the large multi-source remote sensing model of shore, sea, air and space, it compares the fused information with the warning conditions corresponding to the business needs, and controls the management activities in real time based on the comparison results.

[0067] Optionally, when the business demand of the business application system is marine engineering operation management, the corresponding business application system is a marine engineering operation operation management platform, and the corresponding operation monitoring system and management activities are marine engineering operation monitoring systems and video conference activities. The method includes: the marine engineering operation operation management platform generates business demand, and based on the business demand, sends the communication, navigation, and remote sensing satellite resource demand to the communication, navigation, and remote sensing satellite resource scheduling system and data processing system; the communication, navigation, and remote sensing satellite resource scheduling system and data processing system instantly call the corresponding target satellite resources from the operator's communication, navigation, and remote sensing satellite resource system according to the business demand, and based on the target satellite resources, transmit the monitoring data monitored by the marine engineering operation monitoring system and video conference activities to the communication, navigation, and remote sensing satellite resource scheduling system and data processing system; the target satellite resources include communication satellite resources, navigation satellite resources and remote sensing satellite resources; the communication, navigation, and remote sensing satellite resource scheduling system and data processing system fuse the monitoring data received from each target satellite resource to obtain fusion information, and transmit the fusion information to the marine engineering operation operation management platform; the marine engineering operation operation management platform instantly controls the video conference activity corresponding to the business demand based on the fusion information.

[0068] Specifically, when the business demand of the business application system is marine engineering operation management, the corresponding operation monitoring system is the marine engineering operation monitoring system. The monitoring data includes positioning information and satellite remote sensing data. The control and management activity data includes voice and video data. Among them, the positioning information is obtained through the Beidou satellite in the navigation satellite resources, and then transmitted by the high-throughput satellite in the communication satellite resources. The satellite remote sensing data is SAR remote sensing data, which is transmitted by the SAR remote sensing satellite in the remote sensing satellite resources. Voice and video data are transmitted by the high-throughput satellite in the communication satellite resources.

[0069] In specific implementation, the marine engineering operation management platform generates business needs, and based on its own business needs, it sends the communication, navigation, and remote sensing satellite resource needs to the communication, navigation, and remote sensing satellite resource scheduling system and data processing system. The communication, navigation, and remote sensing satellite resource scheduling system and data processing system determine the corresponding target satellite resources based on the received communication, navigation, and remote sensing satellite resource needs, and immediately call the target satellite resources to transmit the monitoring data monitored by the marine engineering operation monitoring system and video consultation activities to the shore, sea, air, and space multi-source remote sensing large model (first, obtain positioning information through the Beidou satellite in the navigation satellite resources, and transmit it to the shore, sea, air, and space multi-source remote sensing large model through the high-throughput satellite in the communication satellite resources. When the SAR remote sensing satellite passes over the target ocean area, the SAR remote sensing data is transmitted to the shore, sea, air, and space multi-source remote sensing large model based on the positioning information through the SAR remote sensing satellite).

[0070] Optionally, the communication, navigation and remote sensing satellite resource scheduling system and data processing system fuse the monitoring data received from each target satellite resource to obtain fused information, including: obtaining surface-level displacement information of the drilling platform in the ocean based on the second monitoring data in the monitoring data; obtaining point-level displacement information based on the first monitoring data in the monitoring data; fusing the surface-level displacement information and the point-level displacement information to obtain displacement information of marine engineering operations; and conducting corresponding video consultation activities when the displacement information meets the verification conditions of the business application system.

[0071] Specifically, the second monitoring data includes satellite remote sensing data (SAR remote sensing data), which is transmitted through remote sensing satellite resources (SAR remote sensing satellites). The first monitoring data includes positioning information, which is obtained through Beidou satellites in navigation satellite resources and transmitted by high-throughput satellites in communication satellite resources.

[0072] In specific implementation, the shore, sea, air and space multi-source remote sensing large model performs common processing and phase comparison on the second monitoring data to obtain the surface-level displacement information of the target ocean area. Furthermore, the shore, sea, air and space multi-source remote sensing large model uses the Beidou high-precision positioning algorithm to calculate the first monitoring data to obtain the point-level displacement information of the communication satellite resource monitoring point. Furthermore, the shore, sea, air and space multi-source remote sensing large model fuses the surface-level displacement information of the target ocean area and the point-level displacement information of the communication satellite resource monitoring point to obtain the displacement information of the marine engineering operation, and transmits the displacement information of the marine engineering operation to the marine engineering operation operation management platform. When the marine engineering operation operation management platform receives the displacement information of the marine engineering operation transmitted by the shore, sea, air and space multi-source remote sensing large model, it compares the displacement information with the verification conditions corresponding to the marine engineering operation. When it is determined that the displacement information meets the verification conditions, the marine engineering operation operation management platform calls high-throughput satellite resources to conduct video consultation activities.

[0073] The method provided in this embodiment, by setting up an ocean engineering operation management platform and instantly calling Qualcomm satellite resources to realize online consultation and disposal methods with the rear, solves the problem of low level of high-precision ocean operations due to insufficient comprehensive application capabilities of satellite resources in current ocean operations, realizes rapid linkage capabilities of efficient operation safety warning and video consultation and disposal, and ensures reliable operation of ocean engineering.

[0074] The method provided in this embodiment, in the first aspect, is a method for collaborative linkage at multiple levels, and the multiple levels include business application systems, communication, navigation, and remote sensing satellite resource scheduling systems and data processing systems, operator communication, navigation, and remote sensing satellite resource systems, and operation monitoring systems and management activities. Among them, at the operation monitoring system and management activity layer, monitoring data of multiple different data types are obtained through multiple monitoring means, and multi-means comprehensive monitoring is realized. At the communication, navigation, and remote sensing satellite resource scheduling system and data processing system layer, by instantly calling the corresponding target satellite resources on demand according to the business needs of the business application system to obtain monitoring data, resource on-demand collaborative scheduling is realized. At the communication, navigation, and remote sensing satellite resource scheduling system and data processing system layer, monitoring data of multiple different data types are ultimately sent to the shore, sea, air, and space multi-source remote sensing large model of this layer, and the shore, sea, air, and space multi-source remote sensing large model performs fusion processing on the received monitoring data, realizing multi-source data fusion. At the business application system layer, by instantly controlling the management activities corresponding to the business needs based on the fusion information sent by the shore, sea, air, and space multi-source remote sensing large model, rapid business collaborative linkage is realized. Through the comprehensive application of operation monitoring systems and management activities, operator communication, navigation, remote sensing satellite resource systems, communication, navigation, remote sensing satellite resource scheduling systems and data processing systems, and business application systems, a multi-level, systematic communication, navigation, remote sensing integrated application service is achieved, from multi-means comprehensive monitoring, on-demand coordinated scheduling of resources, multi-source data fusion to rapid business coordination and linkage. This solves the problem of weak rapid linkage capabilities between multiple business processes in traditional methods, improves the rapid emergency response capabilities of disasters and the efficient execution capabilities of management and guidance activities, can reduce property losses in the first place, and improves the efficient and safe operation management capabilities of the marine industry.

[0075] Secondly, the satellite resource scheduling system and data processing system for communication, navigation and remote sensing determine the target satellite resources for transmitting monitoring data and the calling method of the target satellite resources based on the business needs of the business application system, and call the target satellite resources based on the calling method to realize the reuse of the satellite resource systems of each operator and the unified on-demand scheduling of the satellite resources of the operator, so as to promote the efficient and immediate application of satellite resources by various businesses, and solve the problem of low resource utilization efficiency and high system construction and use costs caused by the traditional method of building various satellite ground systems or independently scheduling various satellite resources. At the same time, it also solves the problem of insufficient business real-time service capabilities caused by insufficient resource integration and coordinated scheduling capabilities of the traditional method. Specifically, this system has the ability to collect various monitoring information using the Beidou satellites, remote sensing satellites, communication satellites and ground system resources of the operator. The system's calling of the operator's satellite resources directly depends on the needs of the business layer, that is, if the business layer needs it, it directly calls mature commercial satellites to obtain the corresponding information, otherwise it does not call it. In this way, the coordinated use of various satellite resources broadens the source of system information and improves the accuracy of system decision-making. At the same time, because satellite resources are called on demand, there is no need to build various satellites and corresponding satellite ground systems separately, which saves the cost of using the system.

[0076] On the third aspect, the large multi-source remote sensing model of shore, sea, air and space in the present application integrates and processes the different types of original monitoring data received based on various types of communication, navigation and remote sensing satellites. Compared with the traditional method of first processing each type of communication, navigation and remote sensing monitoring data separately and then integrating them, it better ensures the synchronization and correlation between various types of data, improves the degree of data fusion, improves the efficiency of data processing, improves the ability to extract intelligent information from various types of monitoring data, and enhances the scientific nature of subsequent control and management activities based on the monitoring data.

[0077] In the fourth aspect, the multiple operation monitoring systems proposed in this application make comprehensive use of multiple satellite communication, navigation and remote control means to obtain different monitoring data of the target ocean area. When obtaining monitoring data in different application scenarios, the order and combination relationship of various satellite communication, navigation and remote control means are different. When obtaining the monitoring data corresponding to marine disasters, the first monitoring data is first obtained by navigation means, and then the second monitoring data is obtained by remote sensing means, and finally the third monitoring data is obtained by communication means. When obtaining the monitoring data corresponding to marine engineering operations, the first monitoring data is obtained by navigation means, and the second monitoring data is obtained by remote sensing means at the same time, and the first monitoring data is transmitted by communication means, that is, the acquisition and transmission of the first monitoring data use navigation means and communication means at the same time. When obtaining the monitoring data corresponding to reclamation, the second monitoring data is first obtained by remote sensing means; then the first monitoring data is obtained by navigation means, and the first monitoring data is transmitted by communication means, and the third monitoring data is obtained by communication means at the same time. In this way, the reliability, accuracy, and real-time performance of the collected data such as marine disaster monitoring, marine engineering operation monitoring, and reclamation illegal construction monitoring are improved, the monitoring data type is enriched, and the monitoring scope is expanded.

[0078] Fifthly, when setting up the marine engineering operation monitoring system, based on the existing SAR satellite periodic monitoring of surface displacement / settlement, Beidou satellites and high-throughput satellites are used to achieve real-time transmission of Beidou high-precision displacement data at each monitoring point, which improves the monitoring accuracy and real-time monitoring capability of marine engineering operations, and can meet the high-precision operation requirements of marine platforms such as drilling platform movement / pile standing. When setting up the marine engineering operation management platform, the real-time call of Qualcomm satellite resources is used to achieve online consultation and disposal methods with the rear, solving the problem of low marine high-precision operation level due to insufficient comprehensive application capabilities of satellite resources in marine operations, achieving efficient operation safety warning and rapid linkage capabilities of video consultation and disposal, and ensuring reliable operation of marine engineering.
