Description

Rescue system and method for a man overboard person}

The present invention relates to a system and a method for quickly rescue a marine distress who has fallen on a ship.

If people fall on the sea, they must be rescued quickly within the viable time. Otherwise, even if they are good swimmers, they will not die for a long time due to temperature drop. Normally 10 hours in summer and 6 hours in winter is a viable time, and if you miss the golden hour, no matter how life jackets are worn, in the end, it is caused by hypothermia at sea.

Since ancient times, many people have been fishing by embarking or dropping fishing gear, but in recent years, the manpower has been greatly reduced due to mechanization. It's changing.

However, in the case of single-person boarding, when a crew member falls into the sea, there is no one to rescue it from the ship, and especially when the crew member goes down to the sea while working slowly while fishing, the hull and the shipwreck Is so far away that there is a serious situation that will never happen again.

In this case, it is virtually impossible for the crew to remain in the sea without communication with land, so rescue the survivors within their survival time.

Although there is a system for checking the safety of fishing boats on a fixed time basis in the land (Fishing and Fisheries Coast Bureau), it is not possible to check the safety in the absence of the crew, and even if the abnormality is confirmed through automatic location reporting The probability of becoming a structure within is very low.

The present invention is conceived as a distress rescue system that is rescued by a magnetic force in a single boarding system.

The first object of the present invention is to disclose a communication network interlocking means for promptly informing the land when the ship's crew falls to the sea and information transmission technology that delivers specialized information to accurately know the authenticity of the land.

A second object of the present invention is to further disclose an automatic control technology for locating and returning a distress when the ship returns to the position of the distress when the ship falls down.

That is, the first embodiment of the present invention

A ship terminal unit (1, for example, a crew terminal), which transmits a distress signal in case of signal connection and emergency in time with a server on board;

By sending periodic beacons to the terminal on the ship, it checks whether the terminal exists in the communication area of the server and receives the distress signal sent by the terminal, but the event packet when the terminal is absent or the distress signal is received. An onboard server unit 2 for generating (event signals) and transmitting them to a communication network associated with the land;

When the absence of the terminal or the distress signal is received, the server unit 2 is configured to link the distress search and the automatic steering unit 9 which returns the vessel to the position at the time of the absence of the terminal by linking the steering of the ship, the engine and the track. It discloses a marine lifesaving device comprising a.

Here, the terminal unit 1 receives a beacon signal transmitted from the inboard server 2 and wears it for life-saving or portable goods of the crew, for example, and returns a response signal indicating that there is no abnormality to the server 2. In addition, the wearer may arbitrarily press a button to generate a distress signal. Furthermore, when the wearer falls to the sea, it is determined that the event state is an electrical insulation failure caused by water pressure or seawater of 0.5 m or more, for example. You can also automatically generate a distress signal. That is, the ultimate connection between the terminal unit 1 and the server unit 2 assumes wireless.

The server unit 2 performs various functions, the first of which is a function of establishing short-range communication with the terminal unit 1. As a signal is transmitted to the beacon, when the terminal transmits a response signal, the server that receives the response determines that the boarder is in a safe state.

To this end, the server is interlocked with the local area communication module 4 via the router or the hub 3. The server can communicate with each other only when the terminal 1 exists within a certain distance through the short-range communication module 4, but if there is no response signal outside the distance on the ship, the server infers that the terminal wearing crew has been distressed.

For this purpose, for example, pan / tilt can be configured so that the user can change the communication range from the horizontal plane to the vertical plane according to the type of ship, quality and propagation characteristics of the ship so that the communication range of the beacon is limited to the shipboard range. Can be.

When the server unit 2 determines the absence of the crew member wearing the terminal, it is preferable to determine when there is no response to the beacon signal at least three times or when the distress signal is received. If it is judged that the distress state in the no response no signal below it is because the malfunction signal is sent to the land can cause confusion to the rescue agency.

In the above, it is referred to as a beacon signal, but is not limited to beacon signals as long as the terminal and the server can transmit and receive signals. However, due to the nature of the ship, it is highly likely that a signal for near field communication is used.

As a second function performed by the server, the server unit 2 generates an event packet when the terminal receives a distress signal from the terminal that is out of the communication right or in the absence of the communication right, and transmits the event packet to the communication network associated with the land. Do this. At this time, the server unit 2 operates the telecommunication module 5 via the routers, bridges, and hubs constituting the network in the ship. That is, the crewman wearing the terminal is urgently informed of the fact that the crew member is distressed through the communication network to the rescue agency on the land or to another vessel in the vicinity.

When the server transmits a distress signal in the terminal unit to easily receive a signal from the terminal, it is preferable to configure the distress signal by automatically raising the output more than a response to the normal beacon signal.

As a third function performed by the server, the server unit 2 includes a router 3 constituting a network on board and a bridge or hub corresponding thereto, as well as a camera 6 or other sensor 8, etc., for the router. It is a function to remotely transmit the status of the ship by interworking. This will be described in the second embodiment.

The fourth function performed by the server is a function that the server unit 2 stores and transmits the tracks, and the fifth function is an onboard steering when the server unit 2 receives the absence of the terminal wearing crew or the distress signal. It is a distress search and automatic steering unit 9 control function for returning a vessel to a position at the time of absence of the terminal by linking an engine and a track.

4A and 4B show the wake and control of the ship, and show the concept of controlling the distress search and the autopilot 9.

That is, the server unit 2 stores the periodic position signal measured by the GPS 7 and stores it as track data. For example, if the location continuously stored at 10-minute intervals is stored as data for one day, and an accident such as distress does not occur, the operation is repeatedly performed to switch to the regular data and delete the temporary data.

If a distress signal is received in the repetitive temporary storage data storage state, the temporarily stored, for example, one-day normal track data is transmitted to the land communication network. In other words, it is to inform the rescue agency of the path of distress while sailing. At this time, in addition to the simple wake-up data, such as the operation state is detected by the sensor to the camera image on the line and sent together to help the search structure greatly.

In addition, the server unit 2 utilizes the track itself, and performs a function of backtracking from the track at the time of distress and returning to the distress position. To this end, the ship turns back to find the distress signal that increases as the track is traced back to the trajectory and controls the engine and steering of the ship at the position of the most predominant signal to select. As a result, a crew member who has crashed into the sea will be able to board the ship on his own return. This regression process can be performed automatically after the distress occurs.

In other words, the distress rescue is carried out before the rescue agency is dispatched from the land, so that a special effect can be obtained by self-rescue within the viable time.

At this time, the track data transmitted to the land transmits the normal track 30 before the event time when the first event packet is transmitted, and transmits the regression track 40 after the event time until after the crew returns from the event time. If configured, the situation of the ship's turning on the ground and rescued by the magnetic force is learned in detail by the function of remote monitoring.

The point at which the returning ship is selected is the point where the distress signal or the beacon response signal is the largest, and the magnitude of the signal strength can be the strength measurement technique (RSSI) of the received signal or the positional search technique (TDOA, etc.) of time difference measurement method. have.

In addition, when the distress signal or the beacon response signal is not normally received, it is possible to determine a point determined by the distress position or a nearby point as the point where the ship selects.

The second embodiment of the present invention

A terminal unit (1) for transmitting a distress signal to the onboard server unit in an acknowledgment response to the beacon periodically transmitted from the onboard server and an event detected by the terminal in case of emergency;

By sending a beacon periodically to the terminal on the ship to check whether there is a terminal in the communication zone of the server, and receives a distress signal sent by the terminal, the event when the absence of the terminal or the distress signal is received An onboard server unit (2) for generating a packet and transmitting the packet to a communication network associated with the land;

The event packet includes a configuration of an event image transmission for temporarily storing the in-board dynamic image captured by the camera 6 in a predetermined frame unit and then transmitting a temporary storage file including an event time to the communication network at the time of event occurrence. A marine lifesaving device is disclosed, and the event packet may include a configuration for transmitting a plurality of track data including position data measured by the GPS 7 as in the first embodiment. .

A function of interlocking the camera 6 as a third function performed by the server will be described.

In this regard, the server unit 2 includes an in-board dynamic image captured by the camera 6 in an event packet, and the image transmits an event image temporarily stored in a predetermined frame unit. Refers to transmitting a retrospective image. As described above, it is effective to use a file temporarily stored in a time unit of about 10 minutes as described above. Also, it is preferable to include other information acquired from the sensor in the video data.

The event packet may include position information (GPS) of the terminal unit, personal information of the wearer including pre-registered crew information, and time information (ETA) at the time of the event.

Reference numeral 100 indicates an integrated acceptance into the navigation installed on the ship. 200 depicts the vessel.

5 is a flowchart showing the main core of the first embodiment and the second embodiment.

That is, the present invention transmits a beacon signal at a given time interval when the crew member boards the ship and departs (101). On the other hand, if it is determined that the response signal is normal, but does not respond for a set period of three or more times (102), the navigation 100 performs distress communication with the land (103), and the normal tracks and the stored The event image is transmitted (104).

In addition, the navigation apparatus 100 controls the steering gear 1005 and starts sailing while backtracking the tracks that have passed. In this process, it is possible to turn at a constant rotation angle, after which the returning track is transmitted (107). As a result, even if the ship is unmanned, it is possible to remotely observe a series of motions in which the ship turns and returns to itself after the accident, as well as the recognition of the time of the accident.

On the other hand, the ship continues to trace back and then moves closer to the crashed crew to capture the increased distress signal strength and selects at the point with the largest signal strength (108, 109). Accordingly, the crew who crashed into the sea will have the effect of returning to the ship or at least hanging from the ship as a lifeboat.

Meanwhile, according to one embodiment, the wind direction, wind speed, tidal current information, and track data may be displayed in a dynamic graphic.

In addition, a small lifeboat can be dropped at the event point. Here, the dropped small lifeboat can automatically travel to the position of the distress in accordance with the instructions.

In addition, the terminal unit may further include a remote control unit capable of remotely controlling the vessel.

Furthermore, since the ship or lifeboat rescued by the distress sails to the position of the distress in autonomous driving, it may hurt the distress in the process of moving to the position of the distress. Accordingly, the vessel or lifeboat may include a sensor (eg, a lidar sensor) capable of detecting a person, and the avoidance operation may be designed so as not to collide with the distress near the distress.

In addition, since the wind direction, currents, and the like after the occurrence of distress affects the path, it is possible to estimate the wake to the distress in consideration of these effects. Such track data can be transmitted to rescue agencies on land. Therefore, the exact location of the distress can be identified and the structure can be made smoothly.

In addition, lifeboats can be automatically dropped after being selected at the position of the distress.

According to another embodiment, when the ship and the rescue ship moves along the track data, there is a possibility that a collision between the ship and the rescue ship occurs. Therefore, the ship data and the rescue ship share the track data, the location of the ship and the rescue ship can be displayed on the map of the map corresponding to the track data. As a result, it is possible to prevent the collision between the vessel and the rescue ship while rescued the distress.

According to another embodiment, when the ship returns to rescue the distress, the rescue may be transmitted to a rescue agency on land to return the rescue boat. Of course, since the treatment of the distress is necessary, the rescue ship can sail to the distress position without turning.
