    DESCRIPTION

    System for detecting the fall of people overboard and rescue them.

    Technical sector 5

    The invention falls within the technical sector of the nautical industry, specifically with the boat safety industry. It can be used well in the sector of transport of leisure people with large ships destined for cruises, but its scope also applies to vessels of any other type 10, and even in which a single occupant can travel.

    Background of the invention

    Accidents occur every year in which a person traveling on a cruise ship or in 15 a smaller ship accidentally falls over the side of the vessel in which they travel. In very few cases the boats are provided with a detection system that begins a protocol to try to recover said fallen person. The effectiveness of these systems is limited and it is possible that a fall will remain undetected with the loss of that person and the practical impossibility of recovering it given the immensity of 20 Mar.

    There are in the state of the art systems and devices to warn of the fall of a passenger from a ship, these systems resort to surveillance cameras and their operation is based on the comparison of images with those of a database, 25 to search between pixels and check if they correspond to a person or not. They work in line with a radar system that detects the physical object that falls.

    There are also known alarm systems that work with RFID technology and that work by moving away from an antenna, this means that they need a system that is in continuous communication. In order for this communication to take place, it is necessary for the user to carry an element that requires a battery, so that user must be responsible for said battery being charged, otherwise the system would not work.
     35
    There are several systems in the state of the art that deal with the detection of a person who falls overboard automatically. Mainly they can be divided into two types of systems:

    - A first type that are those systems that depend on a device that generates a continuous signal and in the absence of that continuous signal the system interprets as a man falling into the water.

    - A second type are those systems that depend on the analytical capacity of devices installed on board that detect the fall of a man into the water. Four. Five

    Within the first type of system there are different types of interpretation of the signal cut: cut of the range of the VHF emission (with an approximate range of 50 meters) or the cut of any other type of wireless link. All these systems transmit the moment of the cut of the link or the contact with the water of the device that generates the continuous signal, automatically generating the warning of Man to the Water.
    The first type systems are associated with buoyancy type vests or devices that are attached to the arm, wrist or ankle of the user and are not comfortable for the user, since the dimensions of the components are high.

    Within this first type of systems, document GB 2 441 561 A is known, which discloses a device that uses an active chip integrated with battery and that continuously emits a signal, assigning to each crew a chip, through a network of Antennas on the boat detect when that signal is lost and once that signal has been lost give the warning of Man to Water.
     10
    Within the second type, only the use of radar technology and a camera, integrated in a detection station, the presence of radar echo and detection through Video Analysis technology where comparing what is detected by the sensor is compared, is known video with patterns from a data bank to give the Man to Water warning, when the person passes in front of the area under study. The reliability of this type of system 15 is guaranteed at 95%.

    However, the second type of system requires the installation of cameras in areas of the boat where, depending on the type of boat they could be anti-aesthetic and expensive to maintain. twenty

    Regarding the reaction to the fall of a Man into the Water, the known devices depend on human performance, and are usually protocols to be followed by the crew of the boat aimed primarily at keeping the situation of the person who has settled and sending devices of buoyancy. To facilitate the shipping work 25 of the buoyancy device there are lifeguards and floating ends that can be launched by means of pyrotechnic devices maximizing the scope of the same.

    For boats of a single crewman there are automatisms that allow the boat not to distance itself from the crewman once the fall has occurred, or even a circle approach. These systems require the installation of a servo-assisted helm and other automatisms to perform the maneuvers once the fall of a Man into the Water has been detected.

    In systems of the first type it is also very complicated for large-sized vessels to ensure coverage of the entire volume of the vessel, going through steel slabs and plates to capture the signal produced by the signal emitting device.

    Explanation of the invention 40

    The system for detecting the fall of people by the side of a boat and salvage the same object of the invention comprises a plurality of passive chips configured to be detected when passing through the area of influence of a radio frequency identification antenna, known as RFID antenna located 45 perimeter in the vessel where the system is installed.

    The radio frequency identification antenna is located below the lower deck of the vessel, and is sectorized so that it covers the entire perimeter of the vessel but with the antenna formed in sections, and its function is to detect step 50
    of a chip through the detection zone that covers the radio frequency identification antenna, so that the passage through that zone activates a Man to Water signal.

    Passive chips are configured to be assigned to a specific person, so that the characteristics of that person are stored in a database. 5

    The system object of the invention has the advantage of avoiding false positives due to the absence of a signal which is how similar systems known to date work, but only the Man to Water signal is activated, when a chip enters the zone of Radio frequency identification antenna detection. 10

    Once the Man on Water signal has been activated, the system warns the bridge of the vessel of the fall of the specific person who has fallen, indicating the area through which the fall has occurred.
     fifteen
    The antenna used in the invention uses RFID technology with a UHF frequency. It is a linear polarization antenna, capable of reading in the 360 or opening. It allows to delimit an area of reading of the chips that exactly coincides with the line of the antenna itself with a range of range that varies with the emission power - reception sensitivity. In this way, an antenna of this type that was formed as a line, would generate a detection zone shaped like a cylinder, the antenna itself being its axis, and shaped as a circumference (but without touching its ends) would generate a detection zone that would be a toroid volume.

    In the presented system, the antenna travels the entire perimeter of the hull, just 1 centimeter from it (as indicated by its technical specifications) and emits perpendicularly in all radial directions. This type of antenna whose main core is composed of Ferrite is very sensitive to the proximity to the metal of the hull. This feature is used to delimit the detection zone and avoid false positives. It is not interesting to detect the chip on the other side of the hull, inside a warehouse, or from 30 above on the deck. Therefore, the proximity to the metal helmet is used and the use of a metal structure as a sun visor that allows its screening in those directions that are not useful for the detection system, specifically upwards.

    System reliability provided the chip is in the reading range is 99%. In a vessel, since the chips are assigned to specific people, the identity of the person who has suffered the fall is known and, given the divisions made in the perimeter, also the area through which the fall occurred.

    The system for detecting the fall of people by the side of a boat and rescue of the same object of the invention comprises:

    - a plurality of chips configured to be assigned to people,

    - an RFID antenna configured to create a detection volume along the perimeter of the vessel,

    - a plurality of readers to capture the RFID antenna signal,

    - a warning system, 50

    - at least one container with marine salvage material:

    - an information management program sent by the readers;

    In the system object of the invention, a chip enters the reading zone of the RFID antenna 5 and activates the warning system so that the marine salvage material of at least one container reaches the same position of the chip once it has precipitated in the water its bearer with it.

    The system for detecting the fall of people by the side of a boat and the rescue of the same object of the invention comprises a platform for integrating the signals emitted by the RFID readers, the speed of the boat, the management system of the alert on the bridge, which can be acoustic and visual, and response management through the opening of the containers.
     fifteen
    The RFID antenna is installed at a distance of at least 1 cm from the vessel's hull and is rescued at the top of the vessel by the side of a vessel and salvage the same object of the invention and is covered at its top by an umbrella-shaped element, whose function is to shield the signal from the RFID antenna by limiting the range and reception angle of said antenna in an upward direction.

    In each container you can find at least the following marine salvage material: a beacon with GPS, a radar responder, a strobe, a smoke device configured to activate on contact with water, a container with 25 colored ink, a buoyancy device and a protective element and fixer of the position within the container of all the mentioned elements. This protector will be made in two halves, from a foam that absorbs the impact of its impact against the sea, safeguarding the material it protects.
     30
    The GPS beacon emits on a detectable radio frequency for the COSPAS-SARSAT satellite network and for search aircraft. The radar responder responds to a radar sweep at a frequency of 9 GHz. The buoyancy device can vary from an approved lifeguard to an inflatable raft. To minimize the space to occupy in the container they will be deflated and equipped with a bottle of compressed gas 35 and a hydrostatic automatism that will force their swelling when they fall into the water. In the event that the inflatable raft had the appropriate size, it could be equipped with a mast at whose end the radar responder would be fixed and that would remain vertical after the raft was inflated, which would increase the detection range of search radars. 40

    The containers of the system object of the invention comprise a door that is opened by a system to choose between an electromagnet that releases a pin that keeps the door closed (in the absence of electric current is kept closed) and a pyrotechnic pin that when triggered by An electrical impulse develops identical function. 45 In any case, they will be equipped with an emergency manual release.

    The container of the system of detection of falling of people by the side of a boat and rescue of the same object of the invention may be located in an inclined orientation so that the exit of the devices inside the container 50
    be by gravity. When falling in the same way that a person would, with the same direction and speed, the discharged devices follow the same path as the fallen person.

    In another embodiment of the container, said container comprises in the interior an element to choose between a spring, a compressed gas or a small pyrotechnic load 5 to drive the fixing element of the position of the devices of the container (with all the fixed elements that protects) and that it leaves the interior of it, without gravity having to act for its exit.

    Preferred Embodiment of the Invention 5

    The system for detecting the fall and rescue of people by the overboard object of the invention comprises:

    - a plurality of UHF RFlD chips (1) configured to be carried by people; 10

    - an antenna (2) RFlD UHF located on the perimeter of the hull of the vessel, below the lower deck of the vessel;

    - readers (3) RFID UHF to capture the signal received by the RFID antenna (2); fifteen

    - warning system (6),

    - at least one container (5) with marine salvage material;
     twenty
    - an information management program sent by the readers;

    - an integration platform (4) of the signals emitted by the RFID readers (3), of the speed of the boat, of management of the alert system on the bridge, which can be acoustic and visual, and of response management through the opening of 25 containers (5).

    Each chip (1) is a passive chip that does not require a battery and is intended to be carried by a single person, so that person on the chip carries an identity that relates to the information included in a database about its person and that will be 30 of great help in case of falling overboard.

    The RFID antenna (2) is divided into sections, so that the vessel in which it is installed in zones is divided. The RFID antenna (2) generates a detection zone (7) in the perimeter of the vessel and detects the passage of any chip (1) through said zone (7). Being 35 individualized areas allows warning on the bridge where the fall occurred.

    The RFID antenna (2) in the preferred embodiment of the invention is placed at a minimum distance of the vessel's hull of 1 cm and is covered by a shielding element (8) that is perpendicular to the vessel, and that in the preferred embodiment of the invention is an "L" profile, with one branch of the L attached to the vessel and the other branch the L protruding from the hull of the vessel. The shielding element (8) has the function of limiting the range of the RFID antenna (2) upwards, with the aim of avoiding chip detections (1) of people who are simply hovering overboard and which would lead to false alarms.

    To guarantee the minimum distance of the RFID antenna (2) to the hull of the boat, in the preferred embodiment of the invention, the RFID antenna (2) is fixed to the hull by rings (11) that are connected to the hull of the boat. fifty

    The operation of the system object of the invention is as follows:

    - when a chip (1) enters the detection zone (7) the readers (3) send a signal to the integration platform (4);
     5
    - at least one alarm occurs in the warning system (6);

    - a calculation is made according to the speed of the vessel and the area of the vessel in which the chip (1) has been detected to drop the contents of the container (5) located at the stern, in order that said content I reached the water in the 10 moment in which the fallen person passes through that point.

    The alarm in the warning system (6) can be an audible alarm, a visual alarm and in the preferred embodiment a specific alarm at the command post of the vessel to communicate the incident. fifteen

    Inside the container (5) is at least:

    - a radio beacon (12) with GPS to facilitate localization by transmitting a radio wave that locates the COSPAS-SARSAT satellite network and 20 search aircraft. the radio beacon offers a range of about 40 hours;

    - a radar responder (13), which reflects the sweep of a radar, operates at a frequency of 9 GHz and the battery offers a range of 96 hours pending receiving the radar signal and 8 hours of emission; 25

    - a strobe light (9) to facilitate the visual location of the person;

    - a smoking device (14) that activates on contact with water and facilitates the visual location of the person; 30

    - a container with colored ink (20) to mark the position in the water of the fallen person;

    - a buoyancy device (21) that can be from a lifeguard to an inflatable raft with a bottle of compressed air (10) for inflation.

    The devices inside the container (5) are not connected to each other with the idea that their different shapes and dredges are not sensitive to the wind in a different way than a person in the water would be. Also inside the container (5) all devices 40 are fixed in position by means of a position fixing element (1S) that can be made of polyurethane foam, for example, to prevent the devices from hitting each other. and be damaged before fulfilling its function.

    The closing of the containers (5) is by means of a door (16) that can be opened in two ways:

    - by means of an electromagnet that releases a pin (17) that keeps the door (16) closed and in the absence of electric current is kept closed,
     fifty
    - by means of a pyrotechnic pin (18) that is triggered electronically or by releasing a spring.

    In any case, the containers (5) also have a manual opening mode in case the previous opening system fails. Furthermore, the design of the door (16) is such that no 5 can prevent the fall of the devices inside the container (5).

    For the exit of the devices inside the container (5) there are also two options:
     10
    - gravity fall, occurs by tilting the container (5) and when the door (16) opens all devices fall to the sea, or

    - with drive, either by means of a spring (19), a compressed gas or a small pyrotechnic charge, in this case the position fixing element (15) of the 15 devices of the container (5) absorbs part of the initial impulse, and that the exit of the container (5) must simulate the fall by gravity of a person.

    The development of the preferred embodiment of the invention carried out previously is intended to serve as a guideline to show a particular development of the invention although the scope 20 of the invention is defined by the following claims.
