Description

TECHNICAL FIELD

[0001] The embodiment of the present application belongs to the technical field of communication and emergency rescue, and particularly relates to a sea emergency rescue method, a rescue terminal and an application system. BACKGROUND

[0002] During sea operation and navigation, personnel falling into water accidents occur frequently. Due to the complex marine environment, limited visual range and other factors, the fallen personnel are difficult to be found and rescued in time, and the life safety of the sea operation personnel is greatly threatened. At present, the common sea emergency rescue system plays a certain role in ensuring the safety of sea personnel, but still has many drawbacks, especially in the aspects of on-site rescue monitoring and information communication.

[0003] For example, the existing sea emergency rescue system mainly relies on the automatic identification system (AIS) and radar for ship dynamic detection, and there are coverage blind areas and cannot accurately locate the fallen individual. For another example, most sea rescues rely on very high frequency (VHF) radio, maritime satellite telephone, Beidou short message communication and the like. Among them, the VHF radio is limited by distance and cannot be rescued at a long distance; the maritime satellite telephone and the Beidou short message device have high cost and complex operation, and in an emergency, the fallen personnel are often difficult to use independently.

[0050] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0051] As mentioned earlier, current maritime emergency rescue systems still have many shortcomings in terms of on-site rescue monitoring and information communication. Firstly, regarding monitoring and early warning, existing maritime emergency rescue systems rely on AIS and radar for vessel dynamic monitoring and weather data from meteorological satellites and coastal observation stations to assist in early warning. However, these monitoring methods have coverage blind spots and insufficient monitoring capabilities for small vessels or areas far from the coast, making it difficult to capture real-time situations when someone falls into the water. For example, when someone accidentally falls into the water, the AIS system can only display the vessel's position and cannot accurately locate the individual. In particular, some rescue equipment has a low level of intelligence; for example, existing life jackets are mostly basic buoyancy devices and lack active distress and location functions. When a person in the water loses consciousness, they cannot actively transmit their location. Secondly, regarding communication system applications, VHF radio is limited by distance and cannot send distress signals over long distances; while maritime satellite phones and BeiDou short message services can achieve global communication, these two devices are expensive and complex to operate. In emergency situations, people in the water cannot effectively use them.

[0052] It is evident that existing maritime rescue systems struggle to effectively locate people in the water during severe weather (such as heavy fog or torrential rain) or at night. Some vessels are equipped with overboard alarms that require manual activation, meaning that when people are incapacitated after falling into the water, they cannot actively send out distress signals, delaying rescue efforts. Furthermore, current rescue communication methods are limited, lacking in positioning accuracy and information transmission efficiency, which can lead to slow rescue response times, increasing the risk to lives and the difficulty of search and rescue for those in the water.

[0053] Therefore, in view of the above problems, this application provides a maritime emergency rescue method, rescue terminal and application system, which can automatically and quickly call for help when a person falls into the water, and can realize the rescue of people who have fallen into the water at low cost based on the integrated sea-air communication system.

[0054] like Figure 1 The diagram illustrates the data communication process in an application scenario applicable to a maritime emergency rescue method provided in this embodiment. After a person falls into the water, the self-distressing distress signal device 101, mounted on the person's life jacket, automatically sends a distress signal to the integrated communication terminal 102 on the ship via an AIS communication link. The integrated communication terminal 102 and the backend maritime emergency rescue platform 104 can achieve two-way BeiDou short message communication based on the BeiDou satellite 103. Therefore, after receiving the distress signal from the self-distressing distress signal device 101, the integrated communication terminal 102 can report relevant information about the person falling into the water to the maritime emergency rescue platform 104 via the BeiDou short message communication link and receive command information from the maritime emergency rescue platform 104. This allows for rapid synchronization of on-site rescue and remote rescue command, improving rescue efficiency and success rate.

[0055] The technical solution of this application will be described below through specific embodiments.

[0056] Reference Figure 2 The diagram illustrates a maritime emergency rescue method provided in an embodiment of this application, which may specifically include the following steps:

[0057] S201. Receive distress information sent by the spontaneous distress device mounted on the life jacket via the AIS communication link.

[0058] It should be noted that the embodiments of this application can be applied to converged communication terminals, that is, the executing entity of this method can be a converged communication terminal, which can be a terminal configured on a ship and capable of simultaneously adapting to the AIS system and the BeiDou short message system. In other words, the converged communication terminal in the embodiments of this application can refer to a terminal device that integrates related technologies such as the AIS system and the BeiDou short message system, and this terminal device can communicate with the AIS system and the BeiDou short message system. For example, such as... Figure 1 The integrated communication terminal 102 installed on the ship shown can communicate with the spontaneous distress device 101 via the AIS communication link, and can also communicate with the maritime emergency rescue platform 104 via the Beidou short message communication link.

[0059] In this embodiment, the spontaneous distress signaling device can be mounted on a life jacket and is capable of automatic monitoring and autonomous distress signaling. After a person falls into the water, the spontaneous distress signaling device can automatically generate distress information and send it to the converged communication terminal on the ship.

[0060] In one possible implementation of this application, the self-rescue device can automatically monitor for people falling into water using built-in or external sensor units. For example, the self-rescue device can be connected to an external water-falling sensor unit, and the data sensed by the water-falling sensor unit determines that a person has fallen into water. The self-rescue device can automatically generate a rescue message based on the person falling into water incident. That is, the rescue message is generated when the self-rescue device detects a person falling into water, and this rescue message can be used to indicate that a person has fallen into water and that relevant personnel need to provide timely rescue.

[0061] In one example, the distress signal may include the identity information of the person in the water and their location in the water. The identity information may be entered into a self-activated distress device when the person is wearing a life jacket or equipped with such a device. For example, any person on board the vessel may pre-enter their personal identity information into a self-activated distress device and then attach the device to their life jacket. Alternatively, the self-activated distress device may be pre-attached to the life jacket, and the person may enter their personal identity information into the self-activated distress device on the life jacket before putting it on.

[0062] The location information of a person falling into the water can be obtained through the positioning unit built into the self-destructive distress device. For example, a positioning unit, such as a BeiDou positioning unit, can be configured in the self-destructive distress device to locate its current position in real time. Since the self-destructive distress device can be attached to a life jacket, when a person wearing a life jacket falls into the water, the location of the self-destructive distress device, as determined by the positioning unit in real time, is the actual location of the person who fell into the water at the moment of fall.

[0063] The self-deployed distress signal device can transmit the identity information and the location of a person who has fallen into the water to the converged communication terminal on the vessel. Specifically, the self-deployed distress signal device can transmit the aforementioned identity information and location information to the converged communication terminal via the AIS communication link.

[0064] In one possible implementation of this application, after the spontaneous distress signaling device is powered on, the converged communication terminal can establish and maintain an AIS communication link with the device. When a person falls overboard, the spontaneous distress signaling device can send distress information to the converged communication terminal through the established AIS communication link. That is, the converged communication terminal on the ship can receive distress information sent by the spontaneous distress signaling device via the AIS communication link when a person falls overboard.

[0065] S202. Based on the distress information, trigger the ship's alarm device to issue an alarm for the incident of a person falling into the water.

[0066] In this embodiment, the vessel may be equipped with alarm devices, such as broadcasting systems, display devices, or warning lights. These alarm devices can proactively alert personnel on board when an accident occurs or other events requiring warning arise. Therefore, after the converged communication terminal receives a distress signal from the spontaneous distress device, it can promptly trigger the vessel's alarm devices to warn of a person falling overboard, enabling relevant personnel to rescue the person in the water in a timely manner.

[0067] In one possible implementation of this application, the alarm device on the ship can be an integrated audio-visual alarm device. Upon receiving a distress signal, the converged communication terminal can extract the identity information and location information of the person who fell into the water from the distress signal, and then use the aforementioned integrated audio-visual alarm device to issue an alarm for the incident in the form of sound, light, and electricity. For example, the integrated audio-visual alarm device can emit a high-decibel alarm sound and flash warning lights after a person falls into the water, alerting relevant personnel that an incident has occurred.

[0068] In addition, the alarm device may also include a display device. While using an integrated audio-visual alarm device to warn of drowning accidents, the device can also display the drowning person's identity information and location. For example, the display device can show the drowning person's name, age, gender, occupation, and other identification information, as well as the specific latitude and longitude of the drowning location.

[0069] In one possible implementation of this application, the water-falling location information displayed by the display device can also be the relative position of the water-falling location to the ship. This relative position can be used to indicate where the water-falling location is on the ship's hull, such as the bow, stern, starboard, or port side of the ship's cabin.

[0070] Specifically, after a person falls into the water and the converged communication terminal has received a distress signal from a spontaneous distress device, the converged communication terminal can extract the location information from the distress signal and determine the relative position of that location to the vessel. Then, the terminal can display the identity information of the person in the water and a schematic diagram of the vessel's external structure, marking the relative position on the diagram. For example, assuming the location is determined to be at the stern, the terminal can display the vessel's hull structure and mark a point at the stern, highlighting or flashing this point to inform relevant personnel of the exact location and facilitate rescue efforts.

[0071] S203. The incident of a person falling into the water is transmitted to the maritime emergency rescue platform via the Beidou short message communication link.

[0072] In this embodiment, the purpose of triggering the ship's alarm device to issue an alarm for a person falling overboard based on the distress message in S202 is to prompt relevant personnel on board to promptly rescue the person in the water, which constitutes on-site rescue. The maritime emergency rescue method provided in this embodiment can also transmit the current situation of the person falling overboard to a backend maritime emergency rescue platform while conducting on-site rescue, thereby utilizing the platform advantages of the maritime emergency rescue platform to implement remote rescue. The implementation of the aforementioned functions of the maritime emergency rescue platform can rely on a server and various terminal devices connected to that server.

[0073] For example, such as Figure 1 The maritime emergency rescue platform 104 shown can achieve two-way BeiDou short message communication with the integrated communication terminal 102 on the ship. Therefore, the integrated communication terminal 102 can transmit information about a person falling overboard to the maritime emergency rescue platform 104 via the BeiDou short message communication link.

[0074] Specifically, after receiving a distress signal from a spontaneous distress device, the converged communication terminal can, on the one hand, issue an alarm through an alarm device, enabling relevant personnel to promptly organize on-site rescue; on the other hand, the converged communication terminal can generate a rescue report based on the distress signal regarding the drowning incident. For example, the rescue report may include the specific incident (person drowning), the drowning person's identity information (such as name, age, gender, etc.), and the drowning location information (latitude and longitude, etc.).

[0075] Since the converged communication terminal will transmit the rescue report information to the maritime emergency rescue platform via the BeiDou short message communication link, the rescue report information should have an information format adapted to the BeiDou short message communication link.

[0076] In one possible implementation of this application, the converged communication terminal can convert the received distress message into a format compatible with the BeiDou short message communication link. Then, based on a preset rescue information template and the converted distress message, a rescue report for a person falling into the water is generated. The rescue information template can be pre-configured in the converged communication terminal, pre-configuring corresponding information text for the incident and leaving blank spaces for personalized information. Thus, upon receiving the distress message, personalized information such as the name, age, gender, and location of the person falling into the water can be extracted and filled into the corresponding blank spaces in the rescue information template, resulting in a rescue report that needs to be reported to the maritime emergency rescue platform.

[0077] In this embodiment of the application, the converged communication terminal reports relevant information about a person falling into the water to the maritime emergency rescue platform. The purpose is twofold: firstly, to inform the platform of the occurrence of the accident, and secondly, to leverage the platform's ability to coordinate the efforts of multiple parties to jointly rescue the person who fell into the water.

[0078] Therefore, upon receiving a report of a person falling overboard from the converged communication terminal, the maritime emergency rescue platform can quickly generate corresponding rescue instructions. For example, the rescue instructions may include a rescue plan, which can be specifically generated based on the situation at the scene of the incident and taking into full account factors such as sea currents and weather. The maritime emergency rescue platform can also transmit the aforementioned rescue instructions back to the converged communication terminal via the BeiDou short message communication link. After receiving the rescue instructions from the maritime emergency rescue platform in response to the rescue report, the converged communication terminal on the ship can broadcast or display the rescue plan to guide rescue operations on board. For example, the maritime emergency rescue platform can promptly assess the potential changes in the location of the person in the water based on information about sea currents, thereby instructing on-site rescue personnel to rescue the person based on the changed location.

[0079] In one possible implementation of this application, after receiving a reported incident of a person falling overboard, the maritime emergency platform can promptly organize relevant sea and air forces to rescue the person. For example, drones can be used to conduct real-time aerial search and rescue of the person in the water, and requests for assistance can be sent to other vessels in the vicinity of the incident area to jointly rescue the person. This application does not limit this aspect.

[0080] The maritime emergency rescue method provided in this application can automatically detect the overboard signal through multimodal sensors, triggering alarms and reporting location data without manual operation, thus achieving automatic and rapid distress signaling. This significantly shortens the time from overboard to sending a distress signal, buying valuable time for rescue. Secondly, this application utilizes existing AIS communication links and the BeiDou short message system to construct communication links between the self-generating distress signaling device and the integrated communication terminal, as well as between the integrated communication terminal and the maritime emergency rescue platform, at low cost. This eliminates the need for building complex dedicated communication networks, reducing system construction and operation costs. Furthermore, the self-generating distress signaling device on the life jacket can adopt a modular design, resulting in a simple structure that facilitates large-scale production and promotion. Thirdly, this application combines AIS communication links to achieve short-range communication between ship and crew, and BeiDou short message system to achieve long-range communication between ship and shore, constructing an integrated sea-air communication network. This integrated sea-air communication ensures that overboard information and rescue conditions can be quickly and accurately transmitted to the maritime emergency rescue platform, which serves as the rescue command center, improving the efficiency of rescue coordination. In addition, the backend maritime emergency rescue platform, based on real-time information received about people falling into the water, can quickly plan the optimal rescue route and dispatch the most suitable rescue forces, reducing rescue decision-making time and enabling rapid response and rescue of people who have fallen into the water.

[0081] It should be noted that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0082] Based on the foregoing method embodiments, this application also provides a maritime emergency rescue application system. For example... Figure 3 The diagram shown is a schematic of a maritime emergency rescue application system provided in an embodiment of this application. The system 300 may include a self-suspension distress signaling device 301, a converged communication terminal 302, and a maritime emergency rescue platform 303. The converged communication terminal 302 is configured on the ship and is communicatively connected to the self-suspension distress signaling device 301 and the maritime emergency rescue platform 303. Specifically, the self-suspension distress signaling device 301 is mounted on a life jacket and connected to the converged communication terminal 302 via an AIS communication link, while the maritime emergency rescue platform 303 is connected to the converged communication terminal 302 via a BeiDou short message communication link.

[0083] The self-generating distress signal device 301 is used to generate distress information when a person falls into the water, and to send the distress information to the converged communication terminal 302 through the AIS communication link. The distress information includes the identity information of the person who fell into the water and the location information of the person who fell into the water.

[0084] The converged communication terminal 302 is used to trigger the ship's alarm device to issue an alarm for the incident of a person falling into the water based on the distress information;

[0085] The maritime emergency rescue platform 303 is used to receive the rescue report information reported by the integrated communication terminal 302 regarding the personnel falling into the water accident via the Beidou short message communication link, and to feed back rescue instruction information to the integrated communication terminal 302. The rescue instruction information includes a rescue plan generated based on the situation at the scene of the fall into the water.

[0086] In this embodiment, the basic function of the self-discharge distress device 301 is as follows: when a person falls into the water, the self-discharge distress device 301 uses its built-in accelerometer and external multimodal sensors, such as a water-falling sensor, to detect the person's water-falling signal and uses a preset algorithm to determine that the person is in the water. Subsequently, the self-discharge distress device 301 will automatically activate its BeiDou positioning and AIS communication functions, and upload the person's identity information, location information, and other data to the ship's converged communication terminal 302 via the AIS communication link.

[0087] The basic function of the converged communication terminal 302 is as follows: upon receiving a distress signal from the spontaneous distress device 301, it immediately triggers the ship's integrated audio-visual alarm system (e.g., emitting a high-decibel alarm sound, flashing warning lights, and displaying the location and identity of the person in the water on a screen), facilitating rapid location of the person in the water and rescue operations by the crew. Simultaneously, the converged communication terminal 302 transmits real-time information about the person in the water and the ship's rescue efforts to the downstream maritime emergency rescue platform 303 via a BeiDou short message communication link.

[0088] The 303-level maritime emergency rescue platform can visualize data based on a geographic information system (GIS), allowing rescue commanders to intuitively grasp the situation at the scene of the drowning and quickly dispatch nearby rescue forces (such as rescue boats, helicopters, drones, etc.) to achieve rapid rescue of the drowning person.

[0089] The following section provides a detailed introduction to the system 300, taking into account the structure and functions of devices and terminals such as the spontaneous distress device 301 and the converged communication terminal 302.

[0090] like Figure 4 The diagram shown is a structural block diagram of a self-sustaining distress device provided in an embodiment of this application. Figure 4 The self-service distress device shown can be Figure 3 The self-deployed distress device 301 in the middle. From Figure 4It can be seen that the spontaneous distress signaling device mainly includes the main control unit (MCU), water-fall sensor unit (Sensor1), acceleration sensor unit (Sensor2), device indicator unit (Indicator), AIS communication unit (Comm_Unit1), BT Bluetooth communication unit (Comm_Unit2), Beidou positioning unit (Comm_Unit3), and power supply unit (PMU), etc. Among them:

[0091] Equipment main control unit: It is responsible for overall equipment control, storing device IDs, processing equipment data and communication protocols, and is an essential unit of the equipment.

[0092] Waterfall sensor unit: It monitors the situation of people falling into the water. Once the waterfall situation is detected, the equipment will initiate a rescue request. It is an essential unit of the equipment.

[0093] AIS Communication Unit: After the equipment initiates a rescue request, it establishes an AIS communication link between the person in the water and the ship's communication fusion terminal. It is an essential unit of the equipment.

[0094] Beidou positioning unit: After the equipment initiates a rescue request, it provides the latitude and longitude location information of the person who fell into the water and uploads it to the ship's communication fusion terminal through the AIS communication link. It is an essential unit of the equipment.

[0095] Power supply unit: Provides power to the entire device. The device can be powered by lithium batteries, which need to be charged. It is an essential unit of the device.

[0096] Bluetooth communication unit: Provides an auxiliary communication channel for the device, facilitating device parameter settings, firmware upgrades, status queries, etc. It is not a necessary unit for the device and can be omitted according to the actual design case.

[0097] Accelerometer sensor unit: Provides status monitoring for the equipment. For example, during a person's fall, the person's status can be determined based on the acceleration data monitored by the accelerometer sensor unit. This unit is not essential to the equipment and can be omitted based on the actual design case.

[0098] Equipment indicator unit: Provides indicator light information for equipment operation, such as charging information indicators and equipment working status indicators. This is not a necessary unit for the equipment and can be omitted according to the actual design case.

[0099] In practical implementation, the water-falling sensor unit can be manufactured separately from the main equipment. This means the sensor unit can be connected to the equipment interface via a cable, and the sensor can share the same interface with an external charging device (such as a charger). For marine applications, fewer interfaces generally mean higher equipment reliability.

[0100] like Figure 5The diagram shown is a schematic representation of the connection between a water-falling sensor unit and an external charging device in a self-rescue device according to an embodiment of this application. Figure 5 The device itself provides a physical interface through which a water-falling sensor unit can be connected when needed. When charging is required, the water-falling sensor unit can be removed from this physical interface and connected to a charging device via the same interface for charging.

[0101] like Figure 6 The diagram shown is a structural block diagram of a converged communication terminal provided in an embodiment of this application. Figure 6 The converged communication terminal shown can be Figure 3 The converged communication terminal 302 integrates the functions of both the AIS and BeiDou (BD_RDSS) systems. Figure 6 It can be seen that the converged communication terminal mainly includes a main control unit, an AIS communication unit, and a Beidou short message communication unit BD_RDSS. It can provide interfaces for the ship's display system and the sound and light alarm system, which are used to connect the display device and the sound and light alarm device, respectively.

[0102] Equipment main control unit: It completes the overall control of the equipment, processes equipment data and performs communication protocol processing, and also provides interfaces for external devices. It is an essential unit of the equipment.

[0103] AIS communication unit: Enables AIS communication with the spontaneous distress signaling device and is an essential unit of the equipment;

[0104] BD_RDSS Communication Unit: also known as Beidou Communication Unit or Beidou Short Message Communication Unit, it completes short message communication with the background emergency rescue platform and is an essential unit of the equipment.

[0105] The working principle of the converged communication terminal is as follows: once a distress call from a person in the water is detected (by receiving a distress signal from a self-generated distress device), the ship's audible and visual alarm devices are immediately activated, and the identity and location information of the person in the water are displayed on the display device, prompting relevant personnel on board to organize a rescue. Simultaneously, the status of the person in the water and the rescue progress are reported to the backend maritime emergency rescue platform via the BeiDou short message system.

[0106] In conjunction with the foregoing embodiments, such as Figure 7 The diagram shown illustrates a spontaneous distress call process provided in an embodiment of this application. Figure 7 The distress call process shown is based on Figure 1 The communication link shown and Figure 3 The maritime emergency rescue system shown is implemented.

[0107] like Figure 7As shown, the self-discharge distress signal device can be modularly mounted on the life jackets worn by personnel on board. Initially, the device operates in a low-power state and can monitor signal status in real time through water-fall sensor units, acceleration sensor units, etc., to determine whether a person has fallen into the water. If a person falls into the water, the self-discharge distress signal device can initiate positioning to obtain the corresponding water location information (such as latitude and longitude). In one example, the self-discharge distress signal device can maintain real-time positioning functionality after power-on; in another example, the self-discharge distress signal device can operate in a low-power state without activating real-time positioning functionality, only initiating positioning based on instructions from the main control unit after confirming a water-fall incident, thus reducing the power consumption of the self-discharge distress signal device. Next, the self-discharge distress signal device reads the device ID and the latitude and longitude information of the water location, and initiates the AIS communication link.

[0108] like Figure 7 As shown, the self-activating distress signal device can use two different distress signal modes based on its own battery level. Both distress signal modes can support continuous alarms until the person in the water is rescued. For example, the two different distress signal modes can be determined based on the alarm frequency of the self-activating distress signal device:

[0109] SOS Mode 1: When the battery level is detected to be ≥80%, the automatic SOS device can report an SOS message every 10 seconds within 1 hour to 2 hours; every 60 seconds within 2 hours to 24 hours; and every 300 seconds within 24 hours to 72 hours.

[0110] SOS Mode 2: When the battery level is detected to be less than 80%, the automatic SOS device can report an SOS message every 10 seconds within 1 hour to 2 hours; every 120 seconds within 2 hours to 24 hours; and every 480 seconds within 24 hours to 72 hours.

[0111] After rescuing a person who has fallen into the water and bringing them ashore or onto a boat, the self-activating distress signal device can detect the remaining battery power. If the battery power is ≥80%, the device can be configured to enter sleep mode. If the battery power is <80%, the self-activating distress signal device can prompt the user to charge the battery for future use.

[0112] Below, we will introduce, with a specific example, how to use the maritime emergency rescue method and application system provided in the embodiments of this application to rescue people who have fallen into the water.

[0113] Example background:

[0114] During a nighttime voyage, a crew member on an ocean-going cargo ship accidentally fell overboard while working on deck. At the time, there was a light fog, visibility was low, and the crew member made no noticeable sound when he fell overboard, making it impossible to detect him in time through manual lookout.

[0115] Rescue process:

[0116] The moment a crew member falls into the water, the water-falling sensor unit in the rescue equipment (automatic distress signaling device) on their life jacket senses the water-falling signal and immediately activates the AIS communication module to send the crew member's location data (such as latitude and longitude information) to the AIS terminal (converged communication terminal) on the ship via the AIS communication link.

[0117] Upon receiving the overboard signal and location data, the ship's AIS terminal triggered the ship's rescue equipment (audio-visual alarm device), emitting a piercing alarm and flashing red warning lights to attract the attention of nearby crew members. Simultaneously, the AIS terminal displayed the exact location of the person in the water on its screen (the ship's display equipment). After quickly confirming the situation, the crew initiated emergency rescue procedures and dispatched a rescue boat to prepare for the rescue.

[0118] The ship's AIS terminal uses the BeiDou short message system to report the location information of the person who fell into the water, the time of falling into the water (year / month / day / hour / minute), the basic information of the crew member (name, age, etc.), and the rescue status of the dispatched rescue boat to the back-end maritime emergency rescue platform in real time.

[0119] After receiving the information, the backend platform accurately marked the location of the person in the water on the GIS map. Based on the distribution of rescue forces in the surrounding sea area, it dispatched the nearest patrol boat and rescue helicopter to provide support. The rescue helicopter arrived first, using aerial observation to further pinpoint the location of the person in the water and dropping rescue equipment to stabilize their condition. Subsequently, the rescue boat and patrol vessel arrived and successfully rescued the crew member.

[0120] Example effect:

[0121] The entire rescue process, from the moment the person fell into the water to their successful rescue, took only 30 minutes, a significant improvement in efficiency compared to traditional rescue methods. Thanks to the advantages of this method and application system—automatic and rapid distress signaling and integrated sea-air communication—the backend maritime emergency rescue platform was able to monitor the situation in real time, accurately allocate rescue resources, and effectively ensure the safety of the person in the water.

[0122] The maritime emergency rescue method and application system provided in this application can automatically trigger an alarm after a person falls into the water, overcoming the drawback of not being able to send an alarm in real time when people are in a panic while in the water, thus improving rescue monitoring and identification performance and rescue efficiency. This application embodiment transmits the fall-in-the-water alarm information via an AIS link, integrating it with the ship's communication system, reducing the cost of building a rescue system. Furthermore, this application embodiment constructs an integrated sea-air communication network by adding a BeiDou short message long-range communication link, ensuring that fall-in-the-water information and rescue status can be quickly and accurately transmitted to the rescue command center (back-end maritime emergency rescue platform), improving rescue coordination efficiency.
