Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a view showing a marine apparatus according to an embodiment of the present invention, and FIG. 2 is a view for explaining the structure and operation principle of the laser apparatus and the radar apparatus of FIG. 1 .

As shown in FIG. 1 , a marine device 90 according to an embodiment of the present invention includes some or all of the laser device 100 , the radar device 110 , the sound output device 120 , and the display device 130 . and may further include a camera or a control device.

Here, "including some or all" means that some components such as the sound output device 120 or the display device 130 are omitted so that the marine device 90 is configured, or some configuration such as the laser device 100 It means that the element can be configured by being integrated with other components such as the radar device 110, and it will be described as including all in order to help a sufficient understanding of the invention.

The laser device 100 is used to measure the height of the sea level and the sea floor by vertically emitting a laser from the bridge 97 to the sea level (or sea floor), and to measure the height of the bridge and the (sea) water level. To this end, the laser device 100 may further include a data acquisition and processing unit, a laser transmitting unit and a laser receiving unit, and a lens unit as shown in FIG. 2A . The data acquisition and processing unit may perform an operation such as converting an analog signal into a digital signal, or may serve as a CPU or MPU, or may operate under the control of the CPU or MPU. For example, the laser device 100 periodically (for example, 5 seconds) measures the height of the sea level and the sea floor, and the height of the bridge and the water surface, stores the measurement results, and then displays the stored measurement results on the display device 130 . However, for example, when it is determined that the vessel 99 enters the bridge 97 under the control of the control unit, measurement is performed on the occasion and appropriate visual information is output through the display device 130 based on this. have.

A laser has a monochromatic nature that generates light of a single wavelength, a straightness with a very small spread of light, a high luminance with very high brightness, a focusing rate that can be focused into a very small size using a lens, and a high energy intensity that can be obtained. It has energy intensity. Because of its unique properties, lasers are widely applied in science and industry, and can be widely used for high-speed Internet, DVD storage media, barcodes, laser surgery, defense, distance measurement and target indicators.

The laser device 100 according to the embodiment of the present invention operates as a water level observation device, and for this purpose, a technique for improving sweep linearity of a Frequency Modulated Continuous Wave (FMCW) radar is applied to improve accuracy. . In addition, signal processing using DSP (Digital Signal Processor) is performed to simplify the device hardware (H/W) and software (S/W) by using a chip that combines major elements through the recently commercialized FMCW radar device. can do. Based on this, the laser device 100 may include a signal processing module and an operation module.

In addition, the radar device 110 measures the distance of the ship 99 approaching the bridge 97 or the facility (water) by launching the radar horizontally with respect to the sea level, and notifying a warning when approaching more than a certain distance. To this end, the radar device 110 includes a transmitter, a receiver, a transceiver, etc. as shown in FIG. 2B , and may further include an antenna. Radar is a device that emits a powerful electromagnetic wave and receives the echo wave that is reflected from the target object to identify the object or detect the position and moving speed of the object. It mainly detects airplanes, ships, cars, clouds, etc. used to do When low-frequency electromagnetic waves with long wavelengths are used for radar, the detection distance is increased due to low attenuation, but the resolution is lowered because it is difficult to identify objects smaller than the wavelength. Conversely, if a high frequency wave with a short wavelength is used, the resolution is increased, but the attenuation is severe because it is absorbed or scattered by moisture, clouds, and air molecules in the air (oxygen molecules are sensitive to specific frequencies). Therefore, the wavelength used by radar is different depending on its purpose. According to an embodiment of the present invention, the radar uses radio waves or microwaves.

The sound output device 120 includes, for example, a horn speaker, and performs a warning notification for the vessel 99 . More precisely, it warns the personnel of the vessel 99 . It can be seen that the control unit such as CPU or MPU notifies by voice that a risk may occur when approaching the bridge 97 based on the measurement result of the laser device 100 or the radar device 110 .

In the process of this, for example, the control unit can determine the nationality of the vessel 99 entering the bridge 97 or the nationality of the person concerned (eg, captain or navigator, etc.) may be For this purpose, the shape of the ship 99 or a specific language can be checked using the captured image of the camera, but in order to increase accuracy, a warning broadcast can be transmitted based on the ship information registered with the local Maritime and Port Administration and the consulate. Of course, there may be various methods for acquiring the nationality information of the ship 99 . For example, all ships must carry a ship's nationality certificate. Therefore, when a communication signal of a communication module mounted in the issuance of a ship nationality certificate is detected, it can be used. Or, if there is a system that provides the location tracking information of a specific vessel, the nationality of the entering vessel 99 is acquired through this, and more precisely, the nationality of the captain or navigator (or helmsman) is identified and broadcasts are transmitted based on this. can In this case, the drone may be sent to the corresponding vessel 99 to determine the nationality. For example, it is possible to make a filming through a drone, receive a captured image, and analyze it to determine the nationality.

As can be seen in FIG. 1 , the display device 130 may display an approach prohibition, a STOP warning display, a water level, and a distance display between the bridge 97 and the sea level, and may be displayed at intervals of 5 seconds. Of course, the display information of the display device 130 may also be controlled under the control of the controller. The display information through the display device 130 may be useful at night, and may be used in parallel with the sound output device 120 at night. Of course, in the case of the display device 130 , the control unit such as the CPU may output the output in the language of the vessel 99 or the nationality of the person concerned based on the nationality. For example, English may be provided by default, but for Russian or Indian ships, information may be provided in the language of the respective country.

Although not separately shown in FIG. 1 , the control device may be configured in the form of an individual device, but may also be mounted and used in a specific device, for example, the laser device 100 . Through this, the overall control operation is performed by interworking with the peripheral devices. The control device may typically analyze the data received through the laser device 100 to measure the water level, the distance between the bridge 97 and the sea level. The measurement result may be stored in a storage unit such as a memory, and the approach distance with the vessel 99 approaching the bridge 97 through the radar device 110 may be measured. The control device may selectively output a warning notice or warning text according to the type of the vessel 99 in order to increase accuracy. For example, when the weight of the entering vessel 99 can be determined or the height or size of the vessel can be determined, a warning notification or the like may be selectively provided based on this. It is possible to measure the size and more precisely the height of the entering vessel through the radar device 110, so based on the result, it is possible to determine whether the bridge 97 has passed and provide an appropriate announcement or warning text. will be.

A marine device according to an embodiment of the present invention, that is, various devices such as the laser device 100 of FIG. 1 are provided inside the enclosure, and the enclosure is essentially made of a waterproof design. In addition, a cradle or a lens mount design for a sensor, that is, a laser or radar sensor is made. Furthermore, the housing is designed in consideration of salt water resistance and the like. Surface treatment in consideration of salt water resistance may be performed in a manner such as coating on the inside and/or outside (surface) of the housing.

FIG. 3 is a diagram illustrating a maritime apparatus according to another embodiment of the present invention, and FIG. 4 is a block diagram illustrating a detailed structure of the maritime apparatus of FIG. 1 or FIG. 3 .

As shown in Figures 3 and 4, the offshore device 190 of Figure 3 according to another embodiment of the present invention is not only the bridge 97 of Figure 1, but also the offshore wind power generation facility (see Figure 2 (a)), And it can be installed and used in large marine structures (refer to (b) of FIG. 2), signal transceivers 400, 410, control unit 420, ship and water level observation unit 430 and warning notification unit (440, 450) ) in part or all, and may further include a storage unit and the like.

Here, "including some or all" means that some components such as a storage unit are omitted, or some components such as a ship and water level observation unit 430 are integrated into other components such as the control unit 420. As meaning that can be configured and the like, it will be described as including all in order to help a sufficient understanding of the invention.

The laser unit 400, the radar unit 410, the control unit 420, the ship and water level observation unit 430, the display unit 440 and the sound output unit 450 of FIG. 4 according to an embodiment of the present invention are hardware modules. , a software module or a combination thereof.

Regarding the offshore wind power demonstration complex in the Southwest Sea, the government is pushing for the creation of an offshore wind power generation complex (99.2MW, 28 units) in Lake Saemangeum along the Northern Limit Line (NLL) in the West Sea and the construction of a wind power equipment factory in the industrial complex zone 2. The Turbine and Foundation Structure EPC site of the West Namhae Offshore Wind Power Demonstration Complex is located in the middle sea between Wido, Buan-gun, Jeollanam-do and Yeonggwang-gun, Jeollanam-do. It is 10 km from Gusipo Port and about 9 km from the nearest sea. The total contract amount of the project was 234.3 billion won, and it was started in 2017 and was scheduled to be completed on November 30, 2019. Such offshore wind power generation facilities are vulnerable to access by ships that are located in the sea. Although a navigational aid facility was installed to block access, great damage was expected if it collided with an offshore wind power facility due to an operational error of the navigational aid facility or the vessel's negligence. It will be possible to prevent damage by applying it to these offshore structures.

In addition, a large marine structure is an abbreviation of “Lange Automatic Navigational Bouy”, and LANBY or guidance light buoy is a large light buoy with a title diameter of 10m or more and a high-intensity light source and various navigational safety support facilities installed with a height of 10m or more above the water surface. . Dangerous shoals, sandbars, and reefs are marked, and the location of land reefs or the access road of the traffic separation zone is marked. Each regional Maritime and Fisheries Administration has about 1 or 2, so the number is not large, but if the operation is stopped, it is an important structure that greatly increases the risk of a sailing vessel. Downtime is expected to be reduced.

The laser unit 400 and the radar unit 410 constituting the signal transceivers 400 and 410 may be configured in the form of a sensor module. In other words, the laser or radar is configured in the form of a semiconductor chip to transmit and receive the laser, and the radar unit 410 may transmit and receive the radar. Of course, the laser unit 400 may include a lens on a semiconductor chip, and the radar unit may include an antenna. The laser unit 400 and the radar unit 410 may include a signal processing module and an operation module, respectively. Signals processed by the laser unit 400 and the radar unit 410 are provided to, for example, analog or digital signals to the control unit 420 .

In the embodiment of the present invention, the laser unit 400 and the radar unit 410 are described for convenience of description, but these may be a ship condition measurement unit or a sea water condition measurement unit. For example, even when measuring the approach of a ship through a camera, it is possible to measure the distance sufficiently through image analysis. When a distance value per pixel is designated, the distance between the bridge and the ship can be measured by multiplying the number of pixels by the designated distance value. In addition, distance or speed can be calculated in this way because distance is obtained when the distance is differentiated, and the distance is obtained when the speed is integrally calculated. In addition, since the height of the vessel can also be measured through image analysis, the embodiment of the present invention will not be specifically limited to a laser or a radar. Of course, rather than operating the camera all the time, it is possible to save power by operating the camera only when an approach of a vessel is detected through RF communication or the like.

The control unit 420 includes the laser unit 400, the radar unit 410, the ship and water level observation unit 430, the display unit 440 and the sound output unit 450 constituting the maritime device 190 of FIG. Responsible for control operation. The data signal or signal data provided from the laser unit 400 and the radar unit 410 is provided to the vessel and the water level observation unit 430 . In addition, the control unit 420 controls the display unit 440 and the sound output unit 450 based on the calculation results provided by the vessel and the water level observation unit 430 , respectively. A pre-stored warning phrase may be displayed on the display unit 440 , and a pre-stored warning broadcast may be transmitted to the sound output unit 450 .

In addition, when the nationality of the entering vessel is determined, the controller 420 may select an appropriate language based on this to transmit a warning phrase or warning broadcast. Although a pre-stored language is simply selected and transmitted, the operation may be performed by performing language conversion based on a specific language (eg, English). As such, the control unit 420 may operate to take appropriate countermeasures based on the vessel's entry state, for example, the distance to the vessel, the height of the bridge and the water surface, the sea level and the sea floor, and the like. For example, when a camera is installed, the camera may be operated when an accident occurs, or the camera may be photographed from the entry situation of the vessel to prepare for the after-action of the accident. Of course, shooting using a drone may be possible, but since it is possible to perform an operation according to an embodiment of the present invention by mounting the marine device 190 on the drone, the embodiment of the present invention is not particularly limited to any one form. won't In this case, it can be very advantageous in terms of power management. For example, if the remaining amount of battery power is measured and reaches a reference value, it is returned to a base, for example, the competent regional Oceans and Fisheries Administration, for power charging.

Of course, the initial setting operation of the marine device 190, that is, the operation performed according to the preset conditions, is installed on a bridge or a structure, and the warning information provided depending on whether it is installed on a bridge or structure in which area is slightly different can do. Typically, the standard value for judgment may be slightly different. Except for this point, it can be seen that the operation of the maritime apparatus 190 according to the embodiment of the present invention is generally similar.

The ship and water level observation unit 430 may measure, for example, the height of the bridge and the water surface, and the height of the sea floor and the sea level, respectively, based on the data signal received by vertically emitting a laser to the sea level. The vessel and water level observation unit 430 may determine whether the entering vessel can safely pass by measuring the height of the bridge and the water surface. Therefore, it may be possible to measure the height as well as the distance of the entering vessel unless it is a case of simply prohibiting the entry.

In other words, when it is determined that the entering vessel has a considerable weight, the vessel and water level observation unit 430 may determine that the height of the sea floor and the sea level is low. In addition, the distance to the ship may be measured based on the data signal for the echo wave received by firing the radar, or the speed may be measured through the measurement distance. By measuring the time at which the radar is launched (t1) and the time at which the radar is received (t2), the speed is measured based on the transmission distance per second of the radar, and the distance can be measured through this. Distance measurements may be made to order to slow down or prohibit entry. However, if it is necessary to pass through a bridge, measure the size of the vessel, such as the height of the vessel exposed from the water surface, through a camera or radar, and compare it with the results of measuring the height of the bridge and water surface to determine whether to pass or not. it might be

Furthermore, the vessel and water level observer 430 may additionally perform an operation for determining the nationality of the vessel in consideration of the vessel of a foreign nationality. It can be known through the analysis of the captured image, but as mentioned above, the identification information of the vessel is received through communication with the vessel, and based on the received identification information, the nationality can be determined by automatically inquiring into the local Maritime and Port Administration. have. The ship and water level observation unit 430 measures the speed by, for example, transmitting the laser or radar at a specified time t1 and then measuring the time t2 at which the echo wave reflected or reflected from the object is received, and the speed The distance can be calculated by integrating the measured values of . The distance or height can be measured through these calculations. For example, if the height of the water surface (h1) is known from the bridge and the height (h2) of the sea floor from the bridge is known, the height (h3) of the sea level from the water surface can be known. That is, h3 = h2 - h1 is calculated.

For example, the display unit 440 and the sound output unit 450 constituting the warning notification units 440 and 450 expose warning phrases or warning broadcasts toward the vessel. More precisely, the ship's personnel listen to the warning broadcast or see the warning text so that appropriate countermeasures are taken. Through this, it is possible to prevent the ship from collided with a bridge or an offshore structure in advance.

In addition, the marine device 190 of FIG. 4 may include a power supply unit or a solar cell. Substantially, the power supply unit may operate in a power saving mode. In addition, it is also possible to periodically charge through the solar cell. Of course, they may be used in combination. For such power management, the maritime device 190 may be implemented by being mounted on the drone. For example, when a system for monitoring about 98 offshore bridges across the country is configured, maritime safety may be further promoted by collectively monitoring the power of the maritime device 190 at the control center.

In addition to the above, in relation to the laser unit 400, the radar unit 410, the control unit 420, the ship and water level observation unit 430, the display unit 440, and the sound output unit 450 of FIG. Since it is not much different from the marine device 90 of

Meanwhile, as another embodiment of the present invention, the controller 420 of FIG. 4 includes a CPU and a memory, and the CPU and the memory may be configured as a single chip. The control unit 420 may include a control circuit, an operation unit (ALU), a command interpretation unit, a registry, and the like, and the memory may include a RAM. The control circuit may perform a control operation, the operation unit may interpret the operation processing of binary bit information, and the instruction interpreter may interpret whether the input binary bit information is related to the performance of any operation. Here, the analysis may be that after matching the data on the left and right sides of the lookup table (LUT), the control circuit finds the data on the right based on the data on the left and performs the operation. The registry is involved in software data storage. According to the above configuration, the CPU copies the program of the ship and the water level observation unit 430 when the maritime device 190 is initially driven, loads it into the memory, and then executes it to quickly increase the data processing speed.
