Description

Technical Field

[0001] This invention relates to the field of emergency communication technology, specifically to a three-dimensional integrated air-space-ground communication command platform. Background Technology

[0002] In responding to major natural disasters such as earthquakes and floods, disaster areas often face a severe situation of "three disruptions": power outages, ground communication disruptions, and road blockages. This makes it difficult to quickly and effectively deploy traditional emergency communication methods that rely on fixed infrastructure, hindering information transmission between on-site rescue teams and the rear command center, and seriously affecting the timeliness and accuracy of rescue decisions.

[0003] In existing technologies, emergency communication solutions mostly focus on optimizing the ground network architecture to meet communication needs in extreme environments. For example, Chinese patent CN119967637A discloses a ground network architecture for emergency communication scenarios with three interruptions. This architecture achieves rapid deployment of the ground network through a combination of intelligent terminal backbone nodes and multiple edge nodes. The backbone nodes serve as access points for satellite communication, while the edge nodes utilize a self-programmable open-source operating system to support low-power wireless transmission and possess basic computing power, enabling local data processing and multi-hop network extension. This solution, to some extent, solves the problems of small coverage, high power consumption, and slow network deployment of traditional portable terminals, and reduces the burden on backbone nodes through edge computing, thereby improving data processing efficiency.

[0004] However, this terrestrial network architecture still has significant limitations. First, its communication resources mainly rely on collaboration between ground nodes, lacking deep integration with airborne (such as drones) and satellite resources. This results in network coverage being significantly limited by terrain, easily creating blind spots in complex disaster environments. Second, although edge nodes possess basic computing power, their computing capabilities are still insufficient for large-scale data collaboration or real-time applications such as high-definition video stream processing. Furthermore, intelligent routing decisions are primarily based on the terrestrial network status, failing to dynamically integrate real-time performance parameters of the air-space-ground multi-dimensional links, thus affecting the priority guarantee of critical service transmission. In addition, this architecture is relatively weak in data fusion and command coordination. Information from different sources is not uniformly processed to form a global situational awareness, and the issuance and execution feedback links of command instructions are not efficient enough to support real-time collaborative operations among multiple parties. Summary of the Invention

[0005] The purpose of this invention is to provide a three-dimensional integrated air-space-ground communication and command platform. By deploying and integrating satellite, ground, and air nodes in stages to construct an integrated air-space-ground communication network, and employing an intelligent fusion control server that includes a software-defined network controller, an intelligent routing engine, an edge computing module, a data fusion module, and a local command and dispatch module, it achieves expanded communication range, improved data transmission efficiency, and more accurate and efficient command and decision-making. It also has adaptive optimization capabilities, controllable cost, rapid deployment, and ease of promotion, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The intelligent fusion control server is used to uniformly schedule and manage the multi-dimensional communication resources in the integrated air-space-ground communication network, and to realize the fusion processing and command coordination of multi-source data on site.

[0009] Preferably, the integrated air-space-ground communication network includes:

[0012] Tethered rotary-wing drones, equipped with public mobile communication micro base stations and ground self-organizing network access units, are used to extend ground network coverage;

[0013] Fixed-wing long-endurance unmanned aerial vehicles (UAVs) equipped with wide-area relay equipment are used for network link extension.

[0014] Preferably, the intelligent fusion control server includes a software-defined network controller; the software-defined network controller is used to abstract the physical communication devices in the integrated air-space-ground communication network into virtual links and switching nodes, and collect the topology status, link performance and load of the entire network in real time to form a unified global network view.

[0015] Preferably, the intelligent fusion control server further includes an intelligent routing engine; the intelligent routing engine dynamically calculates and selects end-to-end transmission paths for different types of service data streams based on the global network view; the selection is based on service priority, real-time quality parameters of each available link, and global load balancing strategy.

[0016] Preferably, the intelligent fusion control server further includes an edge computing module; the edge computing module is used to perform localized real-time analysis of raw video and data streams from on-site reconnaissance drones, camera equipment and sensor nodes, extract key information and generate structured data to reduce bandwidth consumption on satellite links.

[0017] Preferably, the intelligent fusion control server further includes a data fusion module; the data fusion module is used to receive multi-source data processed by the edge computing module, and align the multi-source data to an electronic map using a high-precision spatiotemporal reference as a link, to generate and continuously update a dynamic on-site comprehensive situation map.

[0018] Preferably, the intelligent fusion control server further includes a local command and dispatch module; the local command and dispatch module, based on the comprehensive situation map at the scene, supports commanders to plot on the electronic map and issue action instructions to the handheld smart terminals of personnel at the scene, and supports real-time collaborative consultation between the forward command vehicle, the rear command center and multiple action units at the scene.

[0019] Preferably, the intelligent routing engine is also used to automatically detect restored or newly added network resources on site, and incorporate the restored or newly added network resources into the integrated air-space-ground communication network for unified management and scheduling, and automatically schedule non-urgent business data to the restored or newly added network channels, so as to prioritize the use of core resources for critical business transmission.

[0020] Preferably, the deployment process of the platform includes:

[0021] The advance team, carrying the aforementioned backpack satellite internet terminal, handheld smart terminal, and broadband self-organizing network radio, arrived at the target area first and established a preliminary satellite link and ground self-organizing network.

[0023] Deploy tethered rotary-wing UAVs and fixed-wing long-endurance UAVs to form a complete air-space-ground hybrid communication network.

[0024] Preferably, after the task is completed, the software configuration and task data of the intelligent fusion control server can be completely saved for subsequent review and analysis and to prepare for the next event response.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. This invention deeply integrates the space-based advantages of satellite communication, the air-based flexibility of UAV platforms, and the coverage capabilities of ground self-organizing networks, forming a collaborative and organic whole. It achieves a qualitative change in network coverage from planar to three-dimensional, effectively overcoming the communication blind spot problem caused by complex terrain.

[0027] 2. This invention introduces an intelligent fusion control mechanism with global optimization capabilities, which can perceive the status parameters of satellite links, UAV relays and ground networks in real time, and make dynamic routing decisions based on service priorities and link quality, enabling critical services to automatically select the optimal transmission path, thus ensuring the continuity and stability of command information in the context of fluctuating network resources.

[0028] 3. This invention enables localized preprocessing of massive amounts of on-site data through the collaboration of edge computing and central intelligence. Only high-value information is transmitted back via satellite, greatly alleviating bandwidth pressure. At the same time, multi-source data are fused under a unified spatiotemporal benchmark to generate a panoramic situation map, and support the precise issuance of instructions and real-time consultation among multiple parties.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] To address the challenges of deploying traditional emergency communication methods, such as limited coverage, insufficient data processing capabilities, and low command and coordination efficiency, in situations where major natural disasters cause "three disruptions" (disruption of communication, communication disruptions, and communication disruptions), please refer to [link to relevant documentation]. Figure 1-2This embodiment provides the following technical solution:

[0035] After a disaster occurs, the emergency response mechanism is activated, and the deployment and application of the three-stage integrated air-space-ground communication command platform proposed in this invention immediately commences.

[0036] I. Platform Deployment Process

[0037] Phase 1: Rapidly and initially establishing a communication link

[0038] The advance team, carrying standard equipment, arrived at the target area first by helicopter, off-road vehicle, or on foot. The standard equipment included a backpack satellite internet terminal, a handheld smart terminal, and several broadband self-organizing network radios.

[0039] Upon reaching the target location, the advance team members first deployed backpack satellite internet terminals. These terminals integrate satellite modems and embedded smart routers. After automatically aligning with the satellite and establishing a satellite link, they immediately become remote access points connected to the rear command center, breaking the information isolation caused by the three disconnections and providing initial remote command and information feedback functions using limited bandwidth.

[0040] While the satellite link was established, the team members deployed various broadband self-organizing network radios at key locations. The broadband self-organizing network radios adopted the Mesh networking protocol and automatically searched for and established connections with each other after being powered on, forming a decentralized multi-hop wireless terrestrial network, which was directly connected to the backpack satellite internet terminal.

[0041] The handheld smart terminal serves as the user access point, automatically connecting to the network via a nearby broadband self-organizing network radio. On-site personnel use the handheld smart terminal for voice and text communication and location sharing within their team, and transmit the data back to the command center via satellite link.

[0042] Phase Two: Deployment of Emergency Communication Command Vehicles

[0043] An emergency communication command vehicle equipped with a communication command platform subsequently arrived at the scene. The emergency communication command vehicle is a Python-style all-terrain double-section vehicle. The front vehicle (1) serves as the driving unit, responsible for towing and moving the entire vehicle; the rear vehicle (2) serves as the equipment carrier and command platform, integrating communication equipment, an intelligent fusion control server, and a power supply system. The intelligent fusion control server, acting as the dispatch center, incorporates a software-defined network controller, an intelligent routing engine, an edge computing module, a data fusion module, and a local command and dispatch module.

[0044] Guided by the established satellite link, the Python all-terrain dual-section vehicle selects a suitable area for deployment. Once in place, it quickly deploys the vehicle-mounted satellite antenna 3, which is installed on a liftable bracket on the top of the rear vehicle 2. The liftable bracket can be extended or retracted to reduce wind resistance during driving. Once in place, it immediately rises and uses the vehicle-mounted satellite antenna 3 to establish a second, higher-bandwidth satellite primary link. At the same time, the intelligent fusion control server is powered on and started.

[0045] Phase 3: Deploying Unmanned Aerial Vehicle Systems

[0046] The drone is stored in a dedicated compartment at the rear of the rear vehicle 2. The compartment door can be opened electrically. The top of the rear vehicle 2 is reserved for a drone take-off and landing platform 4 and a tethering and retraction device.

[0047] The tethered rotary-wing drone takes off from the drone launch and landing platform 4 and rises to a height of tens of meters. It obtains continuous power from the power supply system of the rear vehicle 2 through a tether cable and is equipped with a miniaturized public mobile communication micro base station and a ground self-organizing network access unit. After the drone takes off, its onboard communication equipment automatically integrates with the ground self-organizing network. Due to its aerial position advantage, its wireless signal coverage can be rapidly expanded, effectively making up for the coverage blind spots of the ground self-organizing network caused by the terrain, and providing broadband access services for the handheld smart terminals held by on-site personnel.

[0048] Meanwhile, fixed-wing long-endurance UAVs cruise in higher airspaces, carrying wide-area relay equipment and electro-optical reconnaissance payloads, responsible for extending network links and monitoring areas over a wide range.

[0049] At this point, the deployment of a hybrid air-space-ground communication network was completed.

[0050] II. Platform Application Process

[0051] If the aforementioned communication networks were to operate independently, they would suffer from inefficiency and complex management. Therefore, the intelligent fusion control server of the communication command platform has come into play.

[0052] The software-defined network controller configured in the intelligent converged control server establishes connections with all network units such as satellite modems, UAV airborne communication equipment, self-organizing network gateways, and vehicle routers through its interface protocol. The intelligent converged control server abstracts these devices into virtual links and switching nodes with different attribute parameters, and collects the topology status, link performance, and load status of the entire network in real time to form a unified global network view.

[0053] The intelligent routing engine configured within the intelligent converged control server dynamically calculates and selects the optimal end-to-end transmission path for different service data flows based on the aforementioned global network view. Specifically, when on-site personnel initiate a video call request via a handheld smart terminal, the intelligent routing engine first determines the type of the current service and its preset priority. Subsequently, it detects all available wireless access points for the smart terminal, including public mobile communication signals provided by tethered rotary-wing UAVs, nearby ad hoc network nodes, and wide area network signals maintained by long-endurance UAVs. Based on service priority, real-time quality parameters of each available link, and global load balancing strategies, the intelligent routing engine makes a decision in a very short time, selecting an optimal path for the video call. For example, the highest priority video call is designated to be transmitted back via the handheld smart terminal, tethered UAV, and satellite link to the command vehicle, while a regular data report can be guided to the path of handheld smart terminal, terrestrial ad hoc network, and backpack satellite internet terminal, thereby ensuring the continuity and stability of critical services under any network fluctuations.

[0054] The edge computing module within the intelligent fusion control server is the core of on-site data processing. Raw video and data streams from various reconnaissance drones, camera equipment, and sensor nodes are not all transmitted back to the command center; instead, they undergo localized real-time analysis here. For example, massive video streams captured by drones are first analyzed in real-time within the edge computing module. Through its pre-built lightweight analysis model, it automatically identifies key target information in the images. After analysis, the raw, large-volume video data is refined into structured data containing only key information such as event type, geographic coordinates, and timestamps, and then associated with selected key video clips or images. This edge processing mode avoids the massive amounts of raw data consuming the limited bandwidth of satellite links, allowing satellite links to transmit higher-value data.

[0055] The data fusion module configured in the intelligent fusion control server receives all processed multi-source data and aligns all data to an electronic map using the high-precision spatiotemporal reference provided by the satellite navigation system as a link, forming a dynamic comprehensive situation map of the scene. This map is simultaneously displayed and continuously updated on the display terminal of the command vehicle and the large screen of the rear command center. Commanders can intuitively see information and data including the location distribution of personnel from all parties, key areas of concern, risk warnings, task area divisions, and status markers of critical infrastructure.

[0056] The local command and dispatch module configured within the intelligent fusion control server enables efficient collaborative operations based on the aforementioned real-time shared comprehensive situation map. Commanders can directly plot on the electronic map and issue specific action instructions with a single click to the handheld smart terminals of specific teams or individuals. Upon receiving the instructions, the terminals can provide action guidance based on their own location information. During mission execution, the trajectories, statuses, and transmitted on-site information of each unit serve as new information sources fed back into the comprehensive situation map. The platform also integrates multi-party consultation functions, supporting real-time collaboration between forward command vehicles, the rear command center, and multiple on-site action units. Annotations and decisions made during consultations can be overlaid on the comprehensive situation map in real time, ensuring that all participants maintain a consistent understanding of the current situation and the mission.

[0057] The communication command platform proposed in this invention also has adaptive capabilities. As some infrastructure is gradually restored, temporary power is supplied to the site, or public mobile communication networks on the edge of the disaster area are partially restored, the intelligent routing engine automatically detects and discovers these newly added network resources and automatically incorporates them into the communication platform for unified management and scheduling. The platform automatically schedules non-urgent background traffic such as data synchronization and information dissemination to these restored or newly added network channels, thereby prioritizing core resources such as satellite links and dedicated networks for the most critical frontline command, real-time video, and critical data backhaul, enabling the platform's effectiveness to continuously improve as site conditions change.

[0058] After the entire handling task is completed, the software configuration and task data in the intelligent fusion control server can be completely saved, which facilitates subsequent review and analysis and contingency plan optimization, and prepares for rapid response to the next event. The whole solution forms a complete workflow from rapid deployment and intelligent operation to experience accumulation.

[0059] Working principle: The working process of this invention begins with phased rapid network deployment. The advance team first uses backpack satellite terminals and self-organizing network radios to establish an initial satellite link and ground multi-hop network with the rear. The emergency communication command vehicle that arrives later establishes a more powerful primary satellite link and deploys an intelligent fusion control server. Finally, by deploying tethered UAVs and long-endurance UAVs, the network coverage and link relay capabilities are extended from the air, thereby forming a complete three-dimensional communication system.

[0060] The platform's core operating principle lies in the collaborative operation of the intelligent converged control server. The software-defined network controller continuously monitors the real-time status of the entire network, constructing a unified network view. Based on this view, the intelligent routing engine dynamically selects the optimal end-to-end transmission path for service data of different priorities, ensuring the smooth operation of critical services such as video calls. The edge computing module performs localized intelligent analysis on raw video and sensor data collected on-site, extracting valuable structured information and significantly reducing the transmission burden on satellite links.

[0061] The processed multi-source information is integrated into a unified electronic map by the data fusion module, generating a dynamically updated comprehensive situational awareness map to provide intuitive support for command and decision-making. The local command and dispatch module relies on this situational awareness map to accurately issue instructions and facilitate multi-party collaborative consultations, forming a closed-loop command system. Furthermore, the platform possesses adaptive capabilities, automatically identifying and integrating restored or newly added network resources on-site, continuously optimizing resource allocation. At the end of the entire mission cycle, the system's configuration and operational data are fully saved for review and contingency plan optimization, thus forming a complete work cycle from rapid deployment and intelligent operation to experience accumulation.
