Description

Wireless alarm signal for marine lifesaving and marine lifesaving alarm system using same {Wireless alarm signal generator for marine lifesaving and alarm signal generating system for marine lifesaving using the same}

The present invention relates to a marine lifesaving radio alarm signal and a marine lifesaving warning system using the same, and by using a marine lifesaving warning signal installed in a life jacket worn by a user and a mobile terminal wirelessly interworking therewith, the user may have a safety accident It relates to a wireless alarm signal for marine lifesaving and a marine lifesaving alarm system using the same, configured to detect the condition obtained in seawater, generate a visual alarm signal using LED light, and transmit a distress rescue signal to a remote alarm server.

Techniques have been proposed to detect drowning people in distress and prevent drowning accidents.

As an example of this prior art, Korean Patent Registration No. 10-0716518 (registered on May 03, 2007) relates to a GPS wireless distress alarm interworking with a ship and a navigational aid communication network and a wireless distress warning system using the same, and is transmitted from a GPS satellite. We proposed a wireless distress alarm using GPS that can receive information, calculate the exact current coordinates of a person in distress, and transmit a distress signal using this information, and a wireless distress alert system using the same.

However, in the prior art, the GPS receiver is provided with a GPS receiver and a communication unit for communicating with a wireless distress alert repeater provided on an island/sea buoy/lighthouse is provided. There was a limitation in that the unit price would rise to manufacture it. In addition, although the prior art can transmit distress location information, there is a limitation in that it cannot provide visual information identified with the naked eye to a nearby vessel.

As another example of the prior art, Korean Patent Registration No. 10-0375442 (registered on February 26, 2003) relates to a low-power wireless warning system and method for marine lifesaving, carried by each individual aboard a ship, and a maritime accident occurs. Transmitter that detects this, transmits a rescue request signal, and emits a flash signal to notify the location of the victim; and a receiver connected to the transmitter wirelessly, receiving a rescue request signal transmitted from the transmitter, outputting an alert, and requesting a rescue to the outside through a beacon mounted in the ship itself.

However, in the prior art, since a receiver for receiving a rescue request signal transmitted from a transmitter and outputting an alert is installed on a ship, when a shipwrecked person drowns in a ship operating at high speed, the ship's location information and the ship's location information match There was a limit to not being able to do it. In addition, although the transmitter has a flash signal generator and can generate a visual warning signal, the flash signal generator applies a high voltage to a discharge tube in which xenon gas is injected into a glass or quartz tube, so there is a risk of electric shock for use in a marine environment. There is a limitation in that it is difficult to install a high voltage discharge tube in a miniaturized transmitter.

As another example of the prior art, Republic of Korea Patent Registration No. 10-1633347 (registered on June 20, 2016) relates to an automatic distress reporting system using a location identification beacon and a smart device. When an outbreak occurs, it automatically detects the temperature to determine whether or not drowning, and receives the satellite signal transmitted from the GPS satellite from the GPS receiver to accurately determine the current location of the person in distress, and sends a rescue request signal including location information and drowning information to the control center However, the location identification beacon and the smart device transmit and receive information using the low-power Bluetooth method, so that if the distance between the two devices is out of a certain section during fishing activities, it is judged to be out of the sensing range and the location identification beacon We proposed a configuration that automatically requests rescue in the state of drowning or leaving the fishing vessel.

However, in the prior art, since the smart device is installed on a ship, there is a limitation that the location information of the ship and the location information of the shipwreck may not match when a shipwrecked person drowns in a ship operating at high speed. In addition, although the prior art can transmit distress location information, there is a limitation in that it cannot provide visual information identified with the naked eye to a nearby vessel.

Preferably, at least one side of the other end of the cylindrical body 12 and the end face 14, the connecting string coupling hole (17, 17') is formed. For example, the connecting straps 4 are coupled to both ends of the main body 10, respectively, and may be installed in the horizontal direction at the chest position of the life jacket LV. As another example, the connecting string 4 is coupled to one end side of the main body 10 and may be connected and installed to one side (eg, side portion) of the life jacket LV through the connecting string 4 . Through this configuration, as will be described later, the second exposure hole 10b is the water surface (WL) by the dead weight (F1) and the buoyancy force (F2) in a state in which the wireless alarm signal for marine lifesaving (SG) is obtained and floating in water. ) It is possible to obtain an advantageous installation state to achieve a state exposed to the upper portion and to achieve a state in which the first exposure hole 10a is exposed to the lower portion of the water surface WL.

To this end, the left end 20a of the control board part 20 is provided on both inner side surfaces of the cylindrical body 12 so that the control board part 20 can be inserted or withdrawn in a sliding manner along the longitudinal direction (A). ) and the right end 20b may be respectively formed with a left recess 12a and a right recess 12b that can be inserted in a sliding manner (see FIG. 8 ).

Preferably, the end face 14 of the main body 10 includes a concave portion 10a-1 having a periphery concave around the first exposed hole 10a, and The end 22a is installed to be located inside the concave portion 10a-1 (refer to FIG. 4).

Through this configuration, it is possible to prevent as much as possible a situation in which the end 22a of the sensing pin 22 is directly exposed to waves or rainwater, so that (+) , It is possible to prevent a situation in which the end 22a of the sensing pin 22 on the (-) side is energized to each other and erroneously sensed by the acquisition.

On the other hand, the LED pipe 30 is inserted into the second exposed hole 10b and is disposed to extend toward the LED chip 26 , and transmits the LED light projected from the LED chip 26 to the main body portion. (10) is projected outward. As the LED pipe 30 of this embodiment, a known LED pipe made of, for example, a transparent PC (Polycarbonate) material may be used.

For example, if water has been detected, but the movement is not maintained for more than a preset time (eg, 10 seconds), it can be regarded as a case in which the user has been erroneously detected as a water ingestion by waves or rainwater, not as a state in which the user has entered the sea. . In consideration of this, it is further detected whether the movement is maintained for a preset time or longer in a state where water is detected.

When the MCU 28 detects that the movement is maintained for more than a preset time in the state of water detection, the user can actually see it as a distress state obtained at sea, so the LED chip 26 is turned on (ON). ) and transmits a distress detection signal to the mobile terminal 100 (S500). A time when it is determined that the user is in a distress state or a time when a distress detection signal is transmitted may be regarded as a distress detection time.

The distress signal includes user identification information registered through the marine lifesaving application 107, coordinate information at the time of distress detection recognized through the GPS module 109 built in the mobile terminal, and time information at the time of distress detection do.

The alert server 200 transmits the distress rescue signal to the rescue agency terminal 300 when receiving the distress rescue signal from the mobile terminal 100 . The rescue agency terminal 300 that has received the distress rescue signal may transmit a rescue command to the rescue agency vessel at the nearest location in consideration of the coordinate information of the distress detection time and the time information of the distress detection time. In addition, by including the user identification information of the user in distress in the rescue command, the rescuer accurately identifies the user in distress during the rescue operation so that an error does not occur in the rescue operation.
