Description

Technical Field

[0001] This utility model relates to the field of water search and rescue technology, and more specifically, to a split-type marker for indicating the location of a person who has fallen into the water. Background Technology

[0002] Safety and rescue are critical issues that urgently need to be addressed in all activities within the marine economy. Devastating accidents such as grounding, storms, marine life threats, platform / ship collisions, and loss of power can occur, seriously threatening human life and marine economic activities. Failure to solve the problems of maritime distress rescue and alarm systems and reducing casualties will directly impact the development of the marine economy. Position beacons are key equipment for maritime distress rescue and alarm systems, typically integrated into life jackets or worn on the body, used to send location signals after a person falls overboard. Position beacons often employ an integrated design, relying on a positioning module and a radio communication module to achieve distress alarm functionality.

[0003] However, currently used positioning beacons are relatively fixed to the person, and after falling into the water, their weight or obstruction by clothing often prevents the communication module from surfacing, causing signal transmission failure. Specifically, the radio waves emitted by the positioning and communication modules attenuate by over 99% within 1 meter underwater, making it impossible for search and rescue centers to receive location information; the positioning and communication modules also drift underwater due to water interference, resulting in significant positioning errors. All of these factors severely reduce the probability of rescuing people who have fallen into the water. Utility Model Content

[0004] The problem solved by this invention is that traditional locating markers are prone to signal transmission failure after a person falls into the water.

[0005] To solve the above problems, this utility model provides a split-type marker for indicating the location of people who have fallen into the water.

[0006] Firstly, this utility model provides a split-type drowning location marker, comprising:

[0007] The upper target body has a density less than that of water and is equipped with a positioning and communication unit inside.

[0008] The lower part of the marker body has a water-touch switch on its outer side and a control unit and a power supply unit inside it.

[0009] A rope, which has a built-in cable and is connected between the upper beacon and the lower beacon;

[0010] A magnetic attraction structure is provided at the connection between the upper target body and the lower target body;

[0011] When the water-touch switch detects that the object has fallen into the water, the control unit controls the magnetic attraction structure to release, causing the upper and lower targets to separate and then connect via the rope.

[0012] In one embodiment of this utility model, the positioning and communication unit includes an AIS module, a Beidou positioning and communication module, and a 5G communication module.

[0013] In one embodiment of the present invention, the magnetic attraction structure includes a permanent magnet and an electromagnet, wherein the permanent magnet and the electromagnet are respectively disposed on the end faces of the upper target and the lower target that are close to each other.

[0014] In one embodiment of this utility model, lighting lamps are respectively provided on the opposite sides of the upper and lower markers.

[0015] In one embodiment of this utility model, a manual switch is provided on the outer side of the lower marker.

[0016] In one embodiment of the present invention, a rope storage compartment is provided at one end of the lower target body near the upper target body, and the rope is wound around and stored in the rope storage compartment by a locking mechanism.

[0017] In one embodiment of this utility model, the upper marker body is provided with a U-shaped rope anchor at one end near the lower marker body.

[0018] In one embodiment of the present invention, a sensor unit is further provided inside the lower target body, the sensor unit including a body temperature sensor, a pulse sensor and a triaxial acceleration sensor.

[0019] In one embodiment of this utility model, a connecting buckle is provided at one end of the lower target body near the upper target body. The connecting buckle is used to lock the relative positions of the upper target body and the lower target body when the magnetic attraction structure is engaged.

[0020] In one embodiment of this utility model, a mounting buckle is provided on the outer side of the lower target body.

[0021] Compared with existing technologies, the beneficial technical effects of this utility model are as follows: This utility model provides a split-type drowning location beacon, which consists of an upper beacon body with a density less than water and a lower beacon body connected by a magnetic structure. When the water-touch switch detects a drowning signal, the control unit immediately releases the magnetic structure, causing the upper beacon body, which houses the positioning and communication unit, to quickly float to the surface under buoyancy. This completely avoids the problems of severe signal attenuation and transmission failure caused by obstruction by the body or clothing, or by the equipment sinking underwater, greatly improving the success rate of positioning and distress signal transmission. Simultaneously, after the upper and lower beacons separate, the cable inside the rope ensures that the power unit can continuously supply power to the upper beacon body, and data signals can be transmitted; the rope remains connected, allowing the upper beacon body to float freely to the optimal communication position, while the lower beacon body (usually worn by the person) remains intact. Search and rescue personnel can quickly locate the drowning person based on the upper beacon body floating on the surface. Attached Figure Description

[0029] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Although some embodiments of this utility model are shown in the drawings, it should be understood that this utility model can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this utility model. It should be understood that the drawings and embodiments of this utility model are for illustrative purposes only and are not intended to limit the scope of protection of this utility model.

[0030] The term "comprising" and its variations as used herein are open-ended, meaning "including but not limited to"; the term "based on" means "at least partially based on"; the term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments"; and the term "optionally" means "optional embodiments". Definitions of other terms will be given in the following description. It should be noted that the concepts of "first," "second," etc., mentioned in this utility model are only used to distinguish different devices, modules, or units, and are not used to limit the order of functions performed by these devices, modules, or units or their interdependencies.

[0031] It should be noted that the terms "one" and "multiple" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0032] To address the problems existing in the aforementioned related technologies, this embodiment provides a split-type marker for indicating the location of people who have fallen into the water.

[0033] Please see Figures 1-3 Firstly, this utility model provides a split-type water-falling personnel positioning beacon, comprising an upper beacon body 1, a lower beacon body 2, a rope 3, and a magnetic structure. The upper beacon body 1 has a density less than water and is equipped with a positioning and communication unit inside; the lower beacon body 2 has a water-touch switch 21 on its outer side and is equipped with a control unit 22 and a power supply unit 23 inside; the rope 3 has a built-in cable and connects the upper beacon body 1 and the lower beacon body 2; the magnetic structure is located at the connection between the upper beacon body 1 and the lower beacon body 2; wherein, when the water-touch switch 21 detects falling into the water, the control unit 22 controls the magnetic structure to release, causing the upper beacon body 1 and the lower beacon body 2 to separate and be connected by the rope 3.

[0034] Furthermore, to ensure that the position beacon can be quickly and reliably activated regardless of its water-drop posture, the water-touch switches 21 can be arranged in a multi-point configuration, distributed across multiple outer surfaces (including the top and bottom) of the position beacon. This design avoids situations where a single water-touch switch 21 cannot contact the water in time due to obstruction by a person, clothing, or other objects, greatly improving the redundancy and reliability of water-touch detection. It ensures that regardless of the angle at which the device enters the water, at least one water-touch switch 21 can sense and activate the position beacon immediately. The power supply unit 23 can be located at the bottom of the lower beacon body 2 to power the entire position beacon and lower its center of gravity.

[0035] It should be noted that the control unit 22, or central processing unit (CPU), is the "brain" or "core controller" of the entire personnel positioning beacon. Its main responsibilities are to receive signals, make judgments, and execute commands, and to process sensor data, control the startup logic, and operate the positioning communication unit.

[0036] This invention divides the positioning beacon into an upper beacon 1 and a lower beacon 2, connected by a magnetic structure. The density of the upper beacon 1 is less than that of water. When the water-touch switch 21 detects that the beacon has fallen into the water, the control unit 22 immediately controls the release of the magnetic structure, causing the upper beacon 1, which houses the positioning and communication unit, to quickly float to the surface under buoyancy. This effectively avoids severe signal attenuation and transmission failure caused by obstruction by a person or clothing, or by the device sinking underwater, greatly improving the success rate of positioning and distress signal transmission. Simultaneously, after the upper beacon 1 and lower beacon 2 separate, the cable within the rope 3 ensures that the power unit 23 continuously supplies power to the positioning and communication unit within the upper beacon 1, and that data signal transmission can occur between the positioning and communication unit and the control unit 22. The rope 3 remains connected, allowing the upper beacon 1 to float freely to the optimal communication position, while the lower beacon 2 (usually worn by the person) and the upper beacon 1 remain connected. Search and rescue personnel can quickly locate the person in the water based on the upper beacon 1 floating on the surface.

[0037] In one embodiment of the present invention, the positioning and communication unit includes an AIS module 11, a Beidou positioning and communication module 12, and a 5G communication module 13.

[0038] It should be noted that AIS module 11 (Automatic Identification System module) is primarily designed for efficient close-range maritime rescue. It proactively broadcasts the location signal of a person in the water to all nearby AIS-equipped vessels, displaying the distress information directly on their navigation screens. This provides accurate and immediate alerts to the nearest rescue forces (passing vessels), significantly reducing rescue response time, and is particularly suitable for densely populated shipping areas such as merchant shipping lanes. Beidou positioning and communication module 12 serves as the ultimate guarantee for global, blind-spot-free rescue. Utilizing the wide coverage and independence of satellite communication from terrestrial networks, it ensures reliable transmission of location and distress information to national search and rescue centers even in extreme conditions such as offshore areas or areas without public network signals. It also enables two-way communication to confirm successful alarms and coordinate the deployment of specialized rescue forces such as aircraft and ships. 5G communication module 13 primarily serves for high-bandwidth, low-latency, and efficient near-shore communication. Within the coverage area of ​​mobile networks, leveraging their high speed and low latency characteristics, location data and possible additional sensor data (such as vital signs) can be quickly and stably uploaded to the cloud-based rescue platform, providing search and rescue centers with richer decision-making information and enabling access to a wider range of potential rescue resources through public networks.

[0039] Simultaneously, an AIS module 11, a Beidou positioning and communication module 12, and a 5G communication module 13 are set up to form a "triple redundancy communication and positioning guarantee system" covering different scenarios, distances, and standards, which greatly improves the success rate and reliability of distress signals.

[0040] In one embodiment of the present invention, the magnetic attraction structure includes a permanent magnet 41 and an electromagnet 42, which are respectively disposed on the end faces of the upper target 1 and the lower target 2 that are close to each other.

[0041] Please see Figure 4 and Figure 5 It should be noted that the permanent magnet 41 can be set on the lower end face of the upper marker 1. The permanent magnet 41 has fixed magnetism. The electromagnet 42 can be set on the upper end face of the lower marker 2. The electromagnet 42 is electrically connected to the power supply unit 23. When the marker is not activated, it forms an attractive connection with the permanent magnet 41. When the water touch switch 21 detects water falling, the control unit 22 can control the electromagnet 42 to obtain the opposite electromagnetic polarity and repel the permanent magnet 41. At this time, the upper marker 1 and the lower marker 2 automatically separate at the magnetic connection.

[0042] In one embodiment of this utility model, lighting lamps 5 are respectively provided on opposite sides of the upper marker 1 and the lower marker 2. The lighting lamps 5 are used for continuous illumination to enhance visibility and search and rescue identification.

[0043] In one embodiment of this utility model, a manual switch 24 is provided on the outer side of the lower marker body 2. The manual switch 24 is used to manually activate the marker for locating people who have fallen into the water, and can be manually deactivated after use.

[0044] In one embodiment of the present invention, a rope storage compartment 31 is provided at one end of the lower marker 2 near the upper marker 1, and the rope 3 is wound around and stored in the rope storage compartment 31 by a locking mechanism.

[0045] It should be noted that the locking mechanism can be an electromagnetically controlled friction brake mechanism, which actively controls the locking via an electrical signal. It may include an electromagnetic brake, a brake disc, a storage shaft, and a torsion spring. The rope is wound around the storage shaft with the torsion spring, one end of which is connected to the brake disc. The brake pads of the electromagnetic brake (locked when de-energized, released when energized) normally press tightly against the brake disc under the action of their internal springs, preventing the storage shaft from rotating (locked state). The coil of the electromagnetic brake can be connected to the circuit of the control unit 22. When the water-touch switch 21 is activated, the control unit 22 energizes the electromagnetic brake coil, generating magnetic force to overcome the internal spring pressure, causing the brake pads to separate from the brake disc and releasing the lock. The upper beacon 1 can then freely pull the rope 3 upwards under buoyancy.

[0046] In one embodiment of this utility model, a U-shaped rope anchor 32 is provided at one end of the upper marker 1 near the lower marker 2. This anchor is used to fix one end of the rope 3, ensuring tension transmission and line stability.

[0047] In one embodiment of the present invention, the lower body 2 is further provided with a sensor unit, which includes a body temperature sensor 25, a pulse sensor 26 and a triaxial accelerometer 27.

[0048] It should be noted that the lower part of the body 2 has a sensing window or sensing area on the side that contacts the human body. The sensing units of the body temperature sensor 25 and the pulse sensor 26 are arranged in this window and sealed with waterproof and wave-transparent materials (such as medical-grade silicone or specific plastics) to ensure that the sensors can be directly or nearly directly attached to the human skin.

[0049] It should be noted that the control unit 22 has a built-in algorithm for determining the vital signs of a person who has fallen into the water, which can be used to determine whether a person who has fallen into the water is still alive or has drowned. The algorithm is based on the acceleration motion information of the wearer monitored by the triaxial accelerometer 27, the body temperature of the wearer monitored by the body temperature sensor 25, and the pulse of the wearer monitored by the pulse sensor 26. It uses artificial intelligence algorithms to comprehensively determine the vital signs of the person who has fallen into the water, as follows:

[0050] Acceleration information is acquired by a triaxial accelerometer 27. Through coordinate transformation, the acceleration information is converted into acceleration components in a fixed coordinate system, and the influence of gravity is removed, thereby calculating the magnitude of the acceleration vector.

[0051] Calculate the sum of the magnitudes of the acceleration vectors over a period of time, record it as the cumulative acceleration amplitude, and then obtain the cumulative acceleration amplitude of the person who fell into the water;

[0052] Based on the wearer's body temperature monitored by the body temperature sensor 25 and the wearer's pulse monitored by the pulse sensor 26, the average body temperature and average pulse over a period of time are calculated.

[0053] The model inputs the cumulative acceleration, average body temperature, and average pulse of the person who has fallen into the water, along with their corresponding latitude and longitude location and time, into an intelligent vital signs assessment model to obtain the vital signs assessment result (i.e., whether they are still alive or have drowned). This allows for dynamic adjustment of alarm priorities and enrichment of distress information (such as adding medical emergency status), providing search and rescue centers with multi-dimensional intelligence on "location + vital signs," significantly improving rescue efficiency and the chances of survival.

[0054] In one embodiment of this utility model, a connecting buckle 28 is provided at the end of the lower marker 2 near the upper marker 1. The connecting buckle 28 is used to lock the relative positions of the upper marker 1 and the lower marker 2 when the magnetic attraction structure is engaged. The connecting buckle 28 is used to fix the relative positions of the upper marker 1 and the lower marker, preventing relative rotation of the upper marker 1 and the lower marker 2 before the position marker is opened, thus improving stability.

[0055] In one embodiment of this utility model, the outer side of the lower marker 2 is provided with a mounting buckle 29. This is used to fix the marker to the life jacket or life suit. When a person falls into the water, the upper marker 1 and the lower marker 2 separate, but the lower marker 2 remains fixed to the life jacket or life suit by the mounting buckle 29.

[0056] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
