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

The present invention proposes a black box device for a ship. It targets small and medium-sized fishing boats with a high risk of accidents, but is not limited thereto. It is not limited to the ocean but also considers environments such as rivers and lakes. As shown in FIG. 1, the black box is installed on the upper side of the deck and is electrically connected to the engine room of the ship, the steering room (bridge), and the like.

According to the present invention, the main body 10 has a structure with a storage chamber 12 and a polarization dome 16. The main body 10 is formed based on a resin having strength, salt resistance, salt water resistance, heat resistance, weather resistance, and flame retardancy, and in some cases, is formed by partially adding metal. The storage chamber 12 is formed on the side surface of the main body 10 based on FIGS. 1 and 2, and the polarization dome 16 is tightly coupled to the top surface of the main body 10. The storage chamber 12 is formed to have an opening on one side of the main body 10. The polarization dome 16 forms a watertight space therein while blocking light reflected from the surface of the object to improve image quality.

In addition, according to the present invention, the floating body 20 having the controller 22 of the microcomputer circuit is detachably accommodated in the storage chamber 12. The floating body 20 is also formed of a material having physical properties equal to or greater than that of the main body 10. The floating body 20 is configured not to protrude to the outside of the main body 10 in a state coupled to the storage chamber 12. The controller 22 is mounted so that the floating body 20 performs a set operation after a sea accident. The controller 22 is based on a microcomputer circuit with a microprocessor, memory, and input / output interfaces.

At this time, the memory of the controller 22 stores programs and data for performing the set algorithm. The data in the memory also includes information about the ship's clearness, ship number, captain, and IP address.

On the other hand, as shown in Figure 3, the main body 10 can be equipped with a controller 22 of the microcomputer circuit as in the floating body 20.

As a detailed configuration of the present invention, the main body 10 and the floating body 20 perform wireless charging through each power supply 14 and 24 and wireless communication through each communication module 18 and 28. It is characterized by.

Referring to FIG. 3, when the main body 10 and the floating body 20 are combined, the power supply 14, 24 and the communication module 18, 28 correspond. The power supply 14 of the main body 10 receives and converts power from the engine room or steering room of the ship to charge the battery of the floating body 20 wirelessly. Signal transmission and reception between the main body 10 and the floating body 20 is processed through short-range wireless communication such as Bluetooth through the communication modules 18 and 28. According to such a wireless charging and wireless communication method, since any terminal and wire are not exposed to the floating body 20, it is advantageous in improving durability and operational reliability.

Of course, it is not excluded to apply at least partially wired charging or wired communication between the main body 10 and the floating body 20. In this case, it is preferable to add packing to the storage chamber 12 of the main body 10 so as to improve water tightness with the floating body 20.

As a detailed configuration of the present invention, the main body 10 is characterized in that it further comprises a lock 26 to restrain or allow the separation of the floating body 20.

In FIG. 3, a state in which the lock 26 is installed inside the storage chamber 12 of the main body 10 is illustrated. The lock 26 can be configured with a hook, hinge, solenoid, or the like. The hook is capable of engaging a locking groove (not shown) formed in the floating body 20. Normally, the locker 26 restrains the arbitrary separation of the floating body 20, and separation is allowed by the controller 22 under the set conditions described later.

In addition, according to the present invention, the photographing means 30 is a structure that supports a plurality of cameras 36 through the gimbal 32 on the main body 10. 1 and 2, four cameras 36 are mounted on the holder 34 on the upper surface of the main body 10. In addition to the wide-angle function, the camera 36 uses a marine special lens having salt resistance and salt resistance. On the holder 34, an LED light 38 is mounted adjacent to the camera 36. When four cameras 36 are included in the photographing means 30, the gimbal 32 is sufficient to implement a two-axis motion of pitching and rolling, but it may be composed of three or more axes including yawing. In consideration of the ship-mounting environment, the gimbal 32 requires vibration resistance.

In addition, according to the present invention, the detection means 40 for detecting a signal related to a ship accident forms a structure that is installed on at least one of the main body 10 and the floating body 20. The detection means 40 collects or generates all information related to the ship's operational status, accident history, separation of the floating body 20, and the like. Most of the sensing means 40 is advantageously disposed in the main body 10 in order to save battery power of the floating body 20.

As a detailed configuration of the present invention, the detection means 40 is a navigation detector (41) for detecting the navigation information of the ship, the attitude detector (42) for detecting the attitude of the ship and the camera (36), the impact on the ship It is characterized in that it comprises a shock detector (43) for detection, an immersion detector (45) for detecting flooding of the ship, and a GPS module (46) for detecting the positions of the ship and the floating body (20).

3 and 4, there are shown a flight detector 41, a posture detector 42, an impact detector 43, an immersion detector 45, a GPS module 46 constituting the detection means 40, and the like. Although only the GPS module 46 is mounted on the floating body 20 and the rest is mounted on the main body 10, the present invention is not limited thereto, and may be configured redundantly. For example, the immersion detector 45 may be mounted on the floating body 20. The operation detector 41 collects engine engine cycle / view information, steering room audio information, and marine weather information. The posture detector 42 is composed of a part that detects the inclination of the hull and a part that detects the motion of the gimbal 32. The impact detector 43 detects abnormal impacts above a set value applied to the ship. The immersion detector 45 detects the presence of moisture and the change in water pressure. The GPS module 46 is composed of a GPS receiver and a GPS transmitter, and is mounted in the steering room and the floating body 20, respectively. The controller 22 of the floating body 20 inputs and stores the above-described signal in real time through an input interface. In this case, the controller 22 of the floating body 20 may be associated with the controller 22 of the main body 10.

At this time, it is preferable that the sensing means 40 of the present invention further includes a flow rate detector 48. The flow rate detector 48 uses an acoustic wave flowmeter (ADCP) that can be mounted in a compact structure adjacent to the outer surface of the body 10. Of course, the flow velocity detector 48 can also be mounted on the floating body 20. When the ship sinks into the ocean or river, there is a possibility that the floating body 20 may be lost or damaged by a high flow rate. The controller 22 inputs the signal of the flow rate detector 48 through the input interface and maintains the restrained state of the floating body 20 with the locker 26 when the flow rate is greater than or equal to the set value. Of course, if the flow rate of algae or river water is less than the set value, the locking device 26 is operated to allow separation of the floating body 20.

In addition, according to the present invention, the recording means 50 is configured to record the operation information of the ship and the image information of the camera 36 on the floating body 20 in connection with the main body 10. The recording means 50 includes the memory of the controller 22, and the flight information storage unit 52 and the image information storage unit 54 may be configured as separate memory cards. It is recommended that important voice information, such as the contents of the dialogue of the bridge, be separately stored in the voice information storage unit 56 among the ship's navigation information.

In addition, according to the present invention, the airbag 60 inflated in a set condition forms a structure coupled to the floating body 20. The airbag 60 is stored in a folded state on one side of the inside of the floating body 20. In FIG. 4, the controller 22 of the floating body 20 controls the power supply 24, the LED lighting 38, and the GPS module 46 while controlling the deployment of the airbag 60. Even when the floating body 20 is randomly detached from the main body 10 and sinks when the ship crashes, the controller 22 may delay the deployment of the airbag 60 depending on the situation.

As a detailed configuration of the present invention, the airbag 60 is connected to at least one of the high pressure chamber 62 and the inflator, and is further characterized in that it further includes a male expansion member 61 on the inner surface and an antenna wire on the outer surface.

Referring to FIG. 5, an airbag 60, a high pressure chamber 62, and a valve 63 are installed in the floating body 20. The high pressure chamber 62 is filled with high pressure nitrogen and is connected to the air bag 60 through the valve 63. The valve 63 uses an electronic type that can be driven by the controller 22. Although not shown in the figure, a known inflator can be connected to the airbag 60 to develop the explosive force of the gunpowder. In addition, a configuration utilizing a separation reaction of sodium azide (NaN) may be added. When the airbag 60, the high pressure chamber 62, and the valve 63 are mounted on the floating body 20, it is easy to independently determine the floating timing of the floating body 20.

The water expansion member 61 attached to the inner surface of the air bag 60 can be expanded by moisture even when the air bag 60 is perforated to maintain a floating state.

The antenna wire attached to the outer surface of the airbag 60 in a pattern form assists the receiving and transmitting functions of the GPS module 46.

Meanwhile, the airbag 60 may further include a flag-shaped indicator 65 on a part of the outer surface. The rod of the flag consists of a metal material connected to the Antae spiral, and in some cases, a chemistry light capable of luminous display can be added.

It is obvious to those skilled in the art that the present invention is not limited to the described embodiments, and can be variously modified and modified without departing from the spirit and scope of the present invention. Therefore, such modifications or modifications will have to belong to the claims of the present invention.
