Description

Device and method for transmitting distress signal with Buoy

The present invention relates to a buoy distress signal generating apparatus and method for transmitting a distress signal to the ship control center to inform the position of the sunk ship by leaving the marine vessel and floating in the sea when the ship sinks due to stranding or collision of the marine vessel In more detail, the photovoltaic state of the capacitor is used in consideration of a case where it is difficult to collect the solar energy, such as during the sundown at night, using the solar energy as an electric energy for transmitting the distress signal, including a solar panel and a capacitor The present invention relates to a buoy distress signal generating apparatus and method that can increase the reception rate for a distress signal of a control center by changing a distress signal transmission period.

In general, when a ship operating in the ocean is sunk by a stranded or collision due to an accident, there is a buoy (Buoy) installed to rise from the marine vessel to the sea to indicate the sinking position of the vessel.

The buoy is equipped with a wire rope, an emergency position-indicating radio beacon (EPIRB) transmitter and a black box for salvaging the sinking vessel, and are stored in a storage box installed on the vessel. At the same time, the buoy rises due to buoyancy to determine the sinking position.When the final position of the sinking ship is known, the divers are mobilized by connecting grabs or clamps that make up the lifting vessels with wire ropes. It is configured to be lifted immediately without any work.

In general, when the ship is sunk, the buoy embeds a GPS (Global Positioning System) receiver to transmit the GPS-related signals to the ship control center so that the position of the sinking ship can be recognized by the relevant authorities. Since the position movement is caused by the push to the accurate reception of the control center for the GPS signal is required.

Accordingly, the buoy is drawn out of the storage battery and the antenna contained in the inside of the marine vessel at the same time and the electricity supplied from the battery to transmit a predetermined distress signal including the GPS signal is drawn to the buoy outer surface of the continuous distress signal The transmission is made.

However, the storage battery included in the buoy as described above is limited in capacity, and due to the continuous radiation of distress signals, the storage capacity of the battery is mostly consumed before the discovery of the ship. In addition, when sailing to the sea, such as a large ship, the distress signal radiated from the buoy is continuously transmitted in order to smoothly receive the distress signal because the frequency of existence of other ships adjacent to the control center as well as the large ship is low. Since the discharge of the battery is accelerated and the discharging signal transmission is completed within a short time, the discharging signal is discharged with the output, and thus the distress signal of the control center or the nearby ship is not properly received, which causes problems in rescue operations.

Therefore, when the distress signal including the position information of the stranded ship is sent out, the structure of the distress signal is increased quickly by increasing the amount of power of the continuous capacitor to increase the reception rate of the control center for receiving the distress signal. It is an object of the present invention to provide an apparatus and method which can be achieved.

In addition, the present invention is to maintain the power consumption in consideration of the amount of power of the capacitor even when the sailing vessel is stranded in the night, and to transmit the distress signal through the continuous antenna, the control center is distressed through the efficient use of power An object of the present invention is to increase the reception rate for a signal to achieve a structure.

In addition, by sending various distress signals, distress signals can be received not only from the control center but also from other organizations, so that the distress signal can be contacted through the agency where the distress signal was first received. It is an object of the present invention to achieve a quick rescue and lifting operation through cooperation.

In order to achieve the above object, the buoy distress signal generating device according to the present invention is located on the upper surface of the buoy to collect solar light to generate electricity, and a capacitor for storing the electricity generated in the solar panel And a distress signal generator for detecting a power amount of the capacitor, a distress signal generator for generating a distress signal including ship information, such as a ship sinking position, a ship navigation information, a ship registration number, and the distress signal generator. A transmitter for modulating the distress signal provided from the transmitter and transmitting the distress signal through a plurality of channels, and controlling the transmitter to transmit the distress signal when the amount of power of the capacitor falls below a predetermined value through detection of the voltage sensor unit. The distress signal is transmitted by adjusting a transmission ratio between a plurality of channels of the transmitter. It may comprise a control unit.

At this time, the distress signal generating device further comprises a water level sensor for detecting the sinking state of the ship by measuring the water level or water pressure, and the control unit is switched to the wake-up mode on the basis of the detection of the water level sensor in the sleep mode It is possible to supply the power of the capacitor to the distress signal generator and the transmitter.

The transmitter may include an RF unit for modulating the distress signal into an RF signal and transmitting the RF signal; It may include an auxiliary RF unit for transmitting a signal to the special channel is synchronized to the set special channel.

In addition, when the amount of power falls below a predetermined value based on the detection of the amount of power of the voltage sensor unit, the controller may distribute the power of the RF unit, the mobile communication unit, and the auxiliary RF unit by a predetermined ratio to transmit the distress signal. have.

The control unit may include at least one or more numerical values obtained by dividing the total power of the capacitor by a predetermined interval, and a table in which the communication period and the transmission ratio of each channel are preset for each of the predetermined intervals. Whenever the amount of power of the capacitor falls or recovers to a predetermined value, the sensing signal is transmitted to the controller, and the controller converts the distress signal into a communication period corresponding to the detection signal and a transmission weight based on the table. You can send a signal.

On the other hand, in the buoy distress signal generation method for transmitting a distress signal by floating on the water surface in accordance with the detection of the sinking of the ship according to an embodiment of the present invention, the solar panel located on the upper surface of the buoy to collect the sunlight to collect electricity A first step of generating, a second step of detecting a power amount of a capacitor storing electricity generated by the solar panel through a voltage sensor, and ship information such as a ship sinking position, a ship navigation information, a ship registration number, etc. A third step of generating a distress signal, a fourth step of modulating the distress signal, transmitting the distress signal through a plurality of channels, and a detection period of the voltage sensor according to a power amount of a capacitor Compared with the preset table of the transmission ratio of the channel, and adjusts the communication period for transmitting the distress signal through the channel and the channel is composed of a plurality Wu can adjust the transmission ratio between the different channels comprise a fifth step of transmitting the distress signal to a plurality of channels.

It may be characterized in that for transmitting.

In addition, the fifth step may be characterized in that the distress signal is transmitted by converting the power amount of the capacitor to a predetermined value every time the power amount of the capacitor falls or recovers.

In addition, the present invention adjusts the transmission cycle of the communication cycle and the signal transmission channel in consideration of the amount of power of the capacitor even when the sailing vessel is stranded in the night so that the power consumption is kept to a minimum, so that the continuous distress signal is transmitted through the antenna In addition, through such efficient power use, the control center has an effect of increasing the reception rate for the distress signal.

In addition, the present invention transmits a distress signal through a variety of communication channels to receive a distress signal not only in the control center, but also in other institutions to reach the control center through the agency that received the distress signal first, In cooperation with other rescue agencies, it is effective to ensure rapid rescue and lifting operations.

Hereinafter, an apparatus and a method for generating a distress signal of a buoy according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing an embodiment of the process of leaving the buoy in the sinking ship, unlike the configuration that is connected to the ship through a wire rope while the ship is sunk while being buoyant on the water surface while the ship is sunk The buoy is stored in a separate opening and closing storage space located on the deck of the ship, and when the ship is sunk when the frame of the opening and closing storage space is opened as an embodiment to allow the buoy to float.

In the detachment process for the existing wire rope, the wire rope indicates the position of the sinking ship, or a crane installed on the lifting ship used the wire rope as a lifting means using a locking means on the wire rope. However, buoys connected to such wire ropes may cause the wire ropes to be caught by reefs or other obstacles in a bad marine environment, and the buoys may not be supported, and the roller winding the wire ropes may not rotate properly. Otherwise, when the buoys are entangled with each other and the wire ropes are not completely exposed on the surface of the water, the existing buoy distress signal transmitting device does not work properly, resulting in a problem that the ship rescue work cannot be performed. In addition, when the ship is sunk in the deep sea, the buoy may not be exposed to the water surface when the wire rope does not provide a sufficient length.

Therefore, in order to expose the distress signal generator included in the buoy according to the present invention normally on the water surface, the separation process is presented completely separated from the ship, looking at the detailed configuration through the enlarged view of A shown in FIG. Located on the deck of the ship constitutes a storage space in the form of a box, the outer wall of the storage space may be configured in the form of a frame 40 to open and close the storage space by the operation of folding in two stages.

The frame may be attached to the water level sensor 20 or the water pressure sensor 20, the ship sinks through the water level sensor 20 or the water pressure sensor 20 to receive a signal reaching a predetermined level or water pressure The opening and closing process of the frame 40 may be performed through the frame control unit 30.

Meanwhile, the buoy 10 including the distress signal generating device according to the present invention may be provided with a water level sensor 20 or a water pressure sensor 20 on the outer surface similarly formed on the frame and buoy 10 The frame 40 may be opened or closed by transmitting an opening / closing signal to the frame control unit 30 through the water level sensor 20 or the water pressure sensor 20 formed in the frame control unit 30.

In addition, the distress signal generating device of the buoy 10 includes a solar panel 110 and a capacitor 120, by storing the electricity collected through the solar panel 110 in the capacitor 120 by a capacitor ( The solar panel 110 so as to maintain the amount of power required to prevent the problem that the signal transmission is not properly made by floating on the water surface after the distress signal generator due to the natural discharge of the 120 is sinking from the sinking ship By continuously supplying power to the capacitor 120 to maintain a constant amount of power.

Through the configuration as described above, when the ship is sunk as shown, the frame is opened and closed by the water level sensor or the water pressure sensor installed in the frame or buoy, the buoy to rise above the water surface to transmit the distress signal Can be.

On the other hand, the buoy distress signal generating device according to the present invention by continuously supplying and maintaining a sufficient amount of power to the capacitor through the solar panel to maintain the distress signal in charge of the management of sailing vessels such as police as well as the ship control center It is possible to increase the reception rate of the distress signal by transmitting through various channels to the institution. In addition, since there is no means to receive power when the ship sinks during the night, an apparatus and method for efficiently using the amount of power stored in the capacitor will be presented through FIGS. 2 to 6.

Looking at the detailed configuration of the distress signal generation device of the buoy according to the present invention through Figure 2, the solar panel 110 is located on the upper surface of the buoy to collect electricity to generate electricity, and the solar panel 110 Capacitor 120 for storing electricity generated in the, and the voltage sensor unit 130 for detecting the amount of power of the capacitor 120, and ship information such as ship sinking position and ship navigation information, ship registration number, etc. A distress signal generator 150 for generating a distress signal, a transmitter 160 for modulating the distress signal generated by the distress signal generator 150 and transmitting the distress signal through at least one channel; When the amount of power of the capacitor 120 falls below a predetermined value through the detection of the voltage sensor unit 130, the period of transmitting the distress signal is controlled by controlling the transmitter 160, and the transmitter 160When a plurality of channels are configured, the controller 170 may transmit a distress signal to a plurality of channels by adjusting a transmission ratio between different channels.

At this time, the control unit 170 operates in the sleep mode by the detection of the sensor unit 140 consisting of a water level sensor or a water pressure sensor when the ship is sinking the sensor for the sinking state of the ship by reaching a certain level or water pressure When the detection signal of the unit 140 is received, it may be switched to the wakeup mode to apply power.

In addition, the controller 170 determines whether the power supply of the capacitor 120 is immediately replenished by the photovoltaic panel 110 based on the detection of the voltage sensor unit 130, so that the sunken time is Determine whether it is night or daytime.

In the daytime, the control unit 170 may continuously transmit the distress signal. However, in the case of the night, the control unit 170 may not collect current by the solar panel 110. The power amount of the capacitor 120 may be determined based on the detection signal by the voltage sensor unit 130, and the power amount of the capacitor 120 may be efficiently used by adjusting the transmission period of the distress signal through the transmitter 160.

On the other hand, since the reason for transmitting the distress signal is to receive the distress signal as quickly as possible so that the structure is made quickly, the distress signal generator according to the present invention transmits the distress signal through a variety of channels for the sinking By allowing information to be transmitted to various agencies associated with police and ships, as well as ship control centers, organizations that receive distress signals can take precautions to ensure rescue is as fast as possible.

To this end, the transmitter 160 includes a plurality of communication channels, including a plurality of communication channels such as an RF unit 162, a near field communication unit 163, and an auxiliary RF unit 164, as shown in FIG. It may include a switching unit 161 for adjusting the communication ratio for the communication channel. The communication channel is described as an embodiment of the present invention and may be configured to include other communication channels.

The control unit 170 controls the switching unit 161 to minimize the amount of power consumption by adjusting the ratio of sending a distress signal through the communication channels when the amount of power of the capacitor 120 falls below a predetermined value. At the same time, through the various communication channels, it is possible to promptly take preemptive measures and cooperate with other organizations from the agency that first received the distress signal.

Meanwhile, the distress signal generating unit 150 generates a GPS message generating unit 151 for generating position information of a sunken ship, and an SMS message in which ship registration information and information necessary for other distress signals such as a departure point and a destination are preset. It may include an SMS message generating unit 152, the control unit 170 controls the distress signal generating unit 150 according to the amount of power of the capacitor 120 to generate the location information and the SMS message Optionally, it may be delivered to the transmitter 160.

That is, when the power supplemented by the solar panel is present and the amount of power does not fall below a preset value, the controller 170 modulates the distress signal into an RF signal at regular intervals through the RF unit 162. When the number falls below a preset value, the transmission rate is continuously reduced, and the weight of the distress signal transmitted through the RF unit 162 is reduced, and the SMS message is transmitted through a connection with a wireless base station through the short range mobile communication unit 163. Alternatively, the distress signal may be transmitted to various agencies through the auxiliary RF unit 164 which transmits the distress signal in synchronization with a police or a predetermined specific channel.

In addition, the controller 170 presets the specific gravity of the distress signal transmitted through the RF unit 162, the short-range mobile communication unit 163 and the auxiliary RF unit 164 whenever it falls below a predetermined value at a predetermined interval. The distress signal may be distributed by specific gravity, and the distress signal may be transmitted for a long time by minimizing power consumption by extending the period of the transmitter for each predetermined value of a predetermined interval.

When falling below the predetermined value as described above is applicable not only when the ship is sunk at night described above, but also when the power generated by the solar panel is weak due to the cloudy weather at the time of sinking, an appropriate distress signal according to environmental changes. It is possible to change the transmission method of, and to continuously transmit a distress signal when it returns to a predetermined value or more.

4 to 5 are graphs and tables showing an embodiment of the transmission ratio of each communication means included in the transmitting unit according to the amount of power of the distress signal generating apparatus. Referring to FIG. 4, only the RF unit ① when the amount of power is maximum. When the distress signal is transmitted and power is not supplemented, the amount of power decreases and falls below a predetermined value, thereby reducing the transmission weight of the RF unit, and the transmission ratio through the short-range mobile communication unit (②) and the auxiliary RF unit (③). It is possible to increase the reception rate of the distress signal by raising the various agencies to receive the distress signal.

On the other hand, referring to Figure 5, as described above, it is possible to adjust the communication period and the transmission weight of each communication channel in accordance with a predetermined power amount value at a predetermined interval. 5 is an embodiment of a table preset for the communication period and the transmission ratio, the control unit performs RF communication through the RF unit in a T period up to 80% of the power amount, when the power amount falls below 80%, communication The period may be converted to 2T, and the transmission ratios of the RF unit, the mobile communication unit, and the auxiliary RF unit may be converted to 80%, 15%, and 5%, respectively. Even when the amount of power falls below 60%, the communication period and the transmission weight can be converted according to the table as described above. This allows the distress signal to be transmitted for as long as possible depending on the amount of power stored in the capacitor. The setting of such a table is described as an example for the detailed description of the present invention, and the setting of the numerical value, the communication period, and the transmission weight of the amount of power is not limited thereto.

6 is a flowchart illustrating a method for generating a distress signal according to the present invention. When the ship is sunk, the control unit receiving a signal from a water pressure sensor or a water level sensor converts into a wake-up mode and measures a power amount of the capacitor. It may be determined whether the amount of power is supplemented from, and if so, it is possible to transmit the distress signal through the RF unit.

If not supplemented, the distress signal is transmitted through the RF unit, but if the amount of power falls below a predetermined value, the RF unit, the mobile communication unit, and the auxiliary RF unit may convert the predetermined communication period and transmission ratio to transmit. have.

After that, if the replenishment of power does not occur continuously, the distress signal may be transmitted as long as possible by converting the communication period and the transmission weight for each value set at a predetermined interval. On the contrary, when the time zone is changed from night to day, or the weather is changed from cloudy to sunny, and the power is supplied to the capacitor by the solar panel, the communication is performed whenever the recovery is over a predetermined interval. It is possible to return the distress signal by returning the cycle and the transmission ratio to the preset communication cycle and transmission ratio according to the increased power amount, and to continuously transmit the distress signal while maintaining the amount of power of the capacitor in various institutions related to the ship. By increasing the reception rate of can be achieved a quick structure.
