Description

Technical Field

[0001] The present invention relates to the field of wireless communication technology, and more specifically to a sea-air cluster wireless communication networking system. Background Art

[0002] At present, in the field of modern communications, with the increasing frequency of marine economic activities and the increasing demand for national security, the importance of sea-air cluster wireless communication technology has become increasingly prominent. However, when facing the vast sea and complex air environment, the existing sea-air cluster wireless communication system has many technical problems that need to be solved.

[0003] Currently, most existing sea-air cluster wireless communication systems rely on fixed base stations or relay stations for signal forwarding. Such an architecture is not flexible enough when responding to emergencies (such as natural disasters and military operations). Once a base station is damaged or fails, the entire communication network may be paralyzed.

[0004] In addition, traditional communication management systems often encounter problems such as unreasonable resource allocation and long data transmission delays when processing communication requests between large-scale equipment clusters. These problems are particularly prominent in sea-air cluster wireless communication scenarios, because such applications often involve a large amount of real-time data exchange, and any delay may lead to wrong decisions.

[0005] Finally, existing technical solutions often ignore dynamic obstacles (such as ships in sailing and birds in flight) when building communication networks. The existence of these obstacles will cause additional obstacles to signal propagation, thereby affecting the stability and reliability of communication.

[0006] In summary, the current sea-air cluster wireless communication technology faces many problems such as limited coverage, poor anti-interference ability, low security, insufficient flexibility and poor adaptability to dynamic environment.

[0007] Therefore, providing a new generation of sea-to-air cluster wireless communication networking system that can overcome the above-mentioned defects is an issue that needs to be urgently solved by those skilled in the art. Summary of the invention

[0008] In view of this, the present invention provides a sea-air cluster wireless communication networking system, which can not only build a communication network within a single cluster, but also build a communication link across clusters. This means that even under extreme conditions (such as sudden natural events or human interference), the system can maintain the continuity of communication through multiple backup links; at the same time, it can dynamically identify obstacles in the third communication network based on device information and make corresponding adjustments. This function solves the problem of signal attenuation in traditional systems when facing dynamic obstacles (such as ships and aircraft), and improves the reliability and stability of communication.

[0009] In order to achieve the above object, the present invention adopts the following technical solution:

[0010] A sea-air cluster wireless communication networking system comprises: an air equipment cluster, a sea equipment cluster and a communication management subsystem.

[0011] The communication management subsystem includes a device information management module, a communication link module and a network management module.

[0012] The communication link module is used to construct a first communication network for the aerial device cluster, a second communication network for the offshore device cluster, and a third communication network for the aerial device and offshore device clusters.

[0013] The device information management module is used to obtain the device information of the aerial device cluster and the offshore device cluster.

[0014] The network management module is used to identify the obstacle situation of the third communication network according to the device information, and dynamically adjust the third communication network according to the obstacle situation.

[0015] Preferably, the communication management subsystem further comprises a link establishment module, and the link establishment module is used to receive a communication establishment signal and, after identification, select corresponding nodes in the first communication network, the second communication network and the third communication network to establish communication.

[0016] Preferably, the link establishment module identifies the starting node and the target node according to the communication establishment signal, confirms the cross-network communication link in the third communication network according to the starting node and the target node, and establishes communication through the cross-network communication link.

[0017] Preferably, the link establishment module confirms a first relay node according to the inter-network communication link; the first relay node is a starting node in the inter-network communication link, and the ending node of the inter-network communication link is the target node;

[0018] or

[0019] The link establishment module confirms the first relay node and the second relay node according to the inter-network link; the first relay node and the second relay node are respectively the starting node and the ending node of the inter-network communication link.

[0020] Preferably, the device information management module is also used to mark relay nodes in the aerial device cluster and / or the offshore device cluster; and the network management module constructs the third communication network based on the relay nodes.

[0021] Preferably, the network management module includes a GIS submodule and an obstacle identification submodule.

[0022] The GIS submodule is used to obtain topographic information and construct a three-dimensional model based on the topographic information; and is used to receive the relay node information marked in the device information management module; wherein the relay node includes an air relay node and an ocean relay node;

[0023] The obstacle identification submodule is used to confirm the obstacle situation between the aerial relay node and the marine relay node according to the three-dimensional model and the relay node information, and generate multiple barrier-free communication links to form the third communication network.

[0024] Preferably, the network management module further includes a network analysis submodule; the network analysis submodule is used to extract weak signal areas according to the obstacle identification results and confirm relay candidate locations according to the weak signal areas.

[0025] Preferably, the network management module further includes a relay node optimization submodule, and the relay node optimization submodule is used to place corresponding communication equipment according to the candidate positions of the relay nodes.

[0026] Preferably, the obstacle identification submodule includes a ray emitting unit, a path tracing unit and a receiving point detection unit.

[0027] The ray emitting unit is used to confirm the emitting point of the wireless node and emit a plurality of rays at a preset angle and density.

Obviously, the drawings described below are only embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on the provided drawings without paying creative work.

[0034] Figure 2 It is a structural diagram of the network management module in the present invention. DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0036] like Figure 1 The embodiment of the present invention discloses a sea-air cluster wireless communication networking system, including an aerial device cluster, a marine device cluster and a communication management subsystem; wherein the aerial device cluster may include drones, satellites, airships, balloons with wireless communication functions, small aircraft, and aviation sensor nodes, etc.; the marine cluster devices may include ships, unmanned surface vessels, marine buoys and beacons, submersibles, offshore platforms, marine life-saving equipment, and marine sensor nodes, etc.

[0037] The communication management subsystem includes a device information management module, a communication link module and a network management module. The communication link module is used to build a first communication network for the aerial device cluster, a second communication network for the offshore device cluster, and a third communication network for the aerial device and offshore device clusters; the device information management module is used to obtain device information of the aerial device cluster and the offshore device cluster; the network management module is used to identify obstacles of the third communication network according to the device information, and dynamically adjust the third communication network according to the obstacles.

[0038] Among them, both the aerial equipment cluster and the offshore equipment cluster use single-hop information transmission to communicate in the corresponding communication network. When the target node needs to communicate across networks, a multi-hop method is used to select the corresponding node to enter the third communication network and finally jump to the target node to realize cross-network communication.

[0039] In this implementation, the aerial equipment cluster can realize communication under the aerial network in the first communication network; the marine equipment cluster can realize communication under the marine network in the second communication network. When the aerial equipment and the marine equipment need to realize cross-network communication, the third communication network can be used as a bridge between the two to realize cross-network communication.

[0040] In order to further implement the above technical solution, the communication management subsystem also includes a link establishment module, which is used to receive the communication establishment signal and select corresponding nodes in the first communication network, the second communication network and the third communication network to establish communication after identification. The link establishment module identifies the starting node and the target node according to the communication establishment signal, and confirms the cross-network communication link in the third communication network according to the starting node and the target node, and establishes communication through the cross-network communication link.

[0041] Furthermore, the link establishment module confirms the first relay node based on the cross-network communication link; the first relay node is the starting node in the cross-network communication link, and the ending node of the cross-network communication link is the target node; or the link establishment module confirms the first relay node and the second relay node based on the cross-network link; the first relay node and the second relay node are respectively the starting node and the ending node of the cross-network communication link.

[0042] Exemplarily, when an aerial node wants to establish communication with an offshore node, the link establishment module identifies the aerial node as the starting node and the offshore node as the target node; at the same time, a communication link is confirmed in the third communication network based on the starting node and the target node, and the starting point of the link is a wireless node with a relay function in the first communication network (the wireless node can be the starting node itself), and the focus of the link is a wireless node with a relay function in the second communication network (the wireless node can be the target node itself).

[0043] When confirming the communication link in the third communication network, the data transmission direction can be confirmed according to the starting node and the target node, and the communication link with the lower direction angle deviation can be confirmed in the third communication network as the optimal link for communication according to the data transmission direction.

[0044] In addition, the signal attenuation objective function can be constructed based on the data enhancement capabilities of different relay nodes, and the output can be obtained by optimizing the communication link with the least attenuation.

[0045] That is to say, the starting node can enter the third communication network directly or through a nearby relay node. Similarly, the target node can be a node in the third communication network. When the target node is not a node in the third communication network, the data can be forwarded to the target node by utilizing the function of the relay node.

[0046] In order to further implement the above technical solution, in order to build the third communication network, the system needs to grasp the location of the relay node as a node, and also needs to understand the geographic information to form a high-quality communication link between the nodes, thereby forming a third communication network. Therefore, the device information management module is also used to mark the relay nodes in the aerial device cluster and / or the offshore device cluster; the network management module builds the third communication network based on the relay nodes. In addition, the network management module includes a GIS submodule and an obstacle identification submodule; the GIS submodule is used to obtain terrain information and build a three-dimensional model based on the terrain information; it is used to receive the relay node information marked in the device information management module; wherein the relay node includes an aerial relay node and an ocean relay node; the obstacle identification submodule is used to confirm the obstacle situation between the aerial relay node and the ocean relay node based on the three-dimensional model and the relay node information, and generate multiple barrier-free communication links to form a third communication network.

[0047] like Figure 2 The present invention collects the location information of each wireless network node, including aerial device nodes and marine device nodes, through the device management module; obtains data on terrain, landforms, climate conditions, obstacle locations (such as buildings, mountains, islands, etc.), and sea surface conditions (such as wave height), seawater salinity, and seabed terrain through GIS (geographic information system). A model is constructed based on the above information, namely a three-dimensional model and a communication link model. Obstacle identification is performed in combination with the three-dimensional model and the communication link model, thereby obtaining a high-quality barrier-free communication link.

[0048] Furthermore, the network management module also includes a network analysis submodule and a relay node optimization submodule; the network analysis submodule is used to extract weak signal areas according to the obstacle identification results and confirm the relay candidate positions according to the weak signal areas. The relay node optimization submodule is used to deploy corresponding communication equipment according to the relay node candidate positions.

[0049] In this embodiment, the obstacle identification submodule includes a ray emitting unit, a path tracing unit and a receiving point detection unit; the ray emitting unit is used to confirm the emission point of the wireless node and emit multiple rays at a preset angle and density; the path tracing unit is used to control the ray propagation path according to the path of the ray and the nature of the obstacles encountered; the receiving point detection unit is used to calculate the ray energy value reaching the receiving point.

[0050] The path tracking unit can control the propagation path by reflection, refraction or absorption. The receiving point detection unit can confirm the intensity of the rays that can be received by each receiving point by calculating the ray energy value, thereby judging the strength of the signal. For areas with weak signals, additional relay nodes are added by analyzing the signal strength distribution.

[0051] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
