Description

Technical Field

[0002] With the rapid development of the marine economy, the safety requirements for marine operations and navigation are increasing. During marine operations, emergencies such as natural disasters and ship accidents often occur, and these incidents often require reliable communication systems for emergency response. However, traditional communication methods are often limited in the marine environment, making it difficult to meet the complex and changing marine emergency needs and unable to provide stable and efficient communication services.

[0003] A multi-mode converged communication system is a system that integrates multiple communication methods and can dynamically select the most suitable communication method according to the environment. Multi-mode communication systems have been applied in some fields, such as disaster emergency communications and multi-mode terminals in military operations. However, most of these systems are large-scale equipment, mainly used for fixed or vehicle-mounted platforms, and are difficult to deploy quickly and use portable in emergencies at sea. Some studies have explored the combination of satellite and ad hoc network technology to extend the communication range through ad hoc networks in areas that are not covered by satellites. However, such systems still rely on fixed or semi-fixed terminals, and the deployment speed is slow, making it difficult to meet the requirements of portability and flexibility. The high cost and complex equipment are not suitable for common maritime emergency scenarios, especially in the civilian field. Summary of the invention

In this article, where feasible, the embodiments can be combined with each other, features between different embodiments can be replaced or borrowed, and one or more features can be omitted in one embodiment.

[0040] The present application provides a portable multi-mode fusion maritime emergency communication system. Figure 1 The structure diagram of the portable multi-mode fusion maritime emergency communication system is shown in FIG. Figure 1 The system includes: satellite communication module, ad hoc network module, LTE module, WIFI module, data exchange module, data control module, and power module. The following is a detailed introduction to the specific functions of each module.

[0041] The satellite communication module establishes communications with a remote ground command center or other satellite terminals via satellite links, ensuring that voice, data and video information can be transmitted far away from land.

[0042] The self-organizing network module uses self-organizing network technology to realize automatic network formation of multiple nodes and direct communication between multiple nodes; the multiple nodes here include rescue ships, buoy equipment, equipment carried by rescue personnel, etc.

[0043] LTE module, used to connect to 4G / 5G mobile communication network; this module is preferably used in offshore areas connected to ground communication infrastructure, and can also form a small private network base station in the absence of a communication base station. It supports functions such as high-definition video transmission and real-time data transmission.

[0044] The WIFI module is used to provide wireless connection in a local area. It is suitable for scenarios where the distance between devices is short, ensuring short-range wireless data transmission and ensuring smooth communication between rescue personnel and equipment.

[0045] The data exchange module is used to realize the switching of different communication modes. When multiple communication modes coexist, it intelligently selects the optimal path and quickly switches between different modes to ensure the stability and continuity of data transmission.

[0046] Specifically, if within the range of satellite communication signals, communication with the ground command center or other satellite terminals is established preferentially through the satellite communication module;

[0047] If LTE signal is available, switch to LTE mode through the LTE module;

[0048] Local data communication is achieved between devices in close proximity through the WIFI module;

[0049] If there is no external network support, start the self-organizing network module to enable the rescue nodes to form an independent communication network.

[0050] The system continuously monitors network status, including bandwidth, latency, signal strength and other parameters. Based on these monitoring data, the system dynamically adjusts the switching of communication methods to optimize data transmission efficiency. For example, when the rescue ship moves to the LTE signal coverage area, the system will automatically switch from satellite communication to the LTE network.

[0051] Furthermore, the data exchange module is also used for:

[0052] When the system needs to transmit data, it first enters the waiting phase and monitors the wireless channel to confirm that no other devices are currently communicating;

[0053] If the channel is idle, the system will send a request to send signal; after receiving the signal, the receiving end returns a clear to send signal to indicate that it is ready to receive; once the system receives the clear to send signal, it starts transmitting data frames; when the receiving end successfully receives the data frame, it returns a confirmation signal; at the same time, other devices sharing the channel will enter a silent period after receiving the request to send signal or the clear to send signal. During the silent period, no data will be sent in order not to interfere with ongoing communications. Figure 2 A schematic diagram of the sending protocol is shown.

[0054] The data exchange module undertakes the dynamic routing task of the wireless communication network to ensure the stability and reliability of the network connection. In terms of routing strategy, data exchange combines the advantages of static routing and dynamic routing, and combines the characteristics of flooding and on-demand routing to adapt to different network environments.

[0055] The data control module is used to monitor the status and signal quality of all communication links, and regularly check the message queue, and process and distribute the messages in the message queue; according to the preset priority, the messages with higher priority (such as voice, command, alarm, etc.) are sent out through the data exchange module;

[0056] The data control module is connected to other communication nodes through wireless links and can manually configure and adjust the routing path in the wireless network. When the mobile terminal needs to transmit information to the shore-based data system, it can automatically explore the optimal path to other devices by sending a routing query signal.

[0057] The power module is used to provide power supply for each module in the system. The power module is a rechargeable battery with efficient energy management and backup power mechanism to ensure that the system can run for a long time.

[0058] All the above modules are compactly integrated into a portable trolley case or backpack with folding trolleys and wheels, or shoulder straps, which are convenient for operators to carry in various complex environments. It also has good durability, such as waterproof, moisture-proof, dust-proof, shock-proof, etc., which can protect the normal operation of the equipment in harsh marine environments. Figure 3 A schematic diagram of a portable suitcase is shown. Figure 4 A schematic diagram of a portable suitcase after unfolding is shown.

[0059] The embodiment of the present application also provides a portable multi-mode fusion maritime emergency communication method, including:

[0060] Step 1, install the portable multi-mode fusion maritime emergency communication system, and the system automatically detects the status of each module through the self-test function; the portable multi-mode fusion maritime emergency communication system is a portable multi-mode fusion maritime emergency communication system according to the aforementioned embodiment, and the specific constituent modules and specific implementation functions of the system can refer to the aforementioned embodiment.

[0061] Step 2: After the system is powered on, the data control module is activated and is responsible for building and initializing the control logic program. After the data control module is configured, it monitors the status and signal quality of all communication links, and regularly checks the message queue, and processes and distributes the messages in the message queue. The main program will continuously check the message queue in a loop. Once a new message is found, it will be classified and distributed, including forwarding the message or executing the corresponding command. According to the preset priority, the message with higher priority will be sent out through the data exchange module.

[0062] Step 3: The system automatically detects available network resources (satellite signals, ad hoc network nodes, LTE coverage areas or WIFI hotspots) around it and selects stable, high-bandwidth communication methods for connection based on preset priorities. For example, in an ocean environment, satellite communication is prioritized, and in areas close to the shore, LTE is prioritized.

[0063] Step 4: The system automatically switches the communication mode according to the actual situation.

[0064] The data exchange module is automatically activated when the system is started. It is responsible for building and initializing the wireless communication network to ensure the orderliness of communication. The protocol based on request to send / clear to send is adopted to reduce conflicts in communication. The main goal is to minimize data conflicts and avoid conflicts between terminals through handshake exchanges.

[0065] Step 5: When the emergency is over, the system stores all transmitted data and operation records and generates detailed logs for analysis. The operator turns off the device and the portable device can be quickly restored to its initial state and ready for the next deployment.

[0066] In summary, this application has the following technical effects:

[0067] 1. This application combines satellite communication, ad hoc network, LTE and WIFI technologies, and can provide stable communication services in different environments. The system guarantees the multi-level needs of emergency communication. It realizes the emergency communication guarantee needs in environments without long, medium and short range communication infrastructure.

[0070] 4. Compared with general emergency communication equipment, this application has stronger environmental adaptability, and is especially suitable for long-term operation in the marine environment, which greatly improves the stability and reliability of the equipment.
