FIELDING DEVICE FOR HELDECK AND CONTROL METHOD THEREOF FIELDING DEVICE FOR HELDECK AND CONTROL METHOD THEREOF

FIELD OF THE INVENTION The present invention relates to a helicopter fire fighting apparatus and a control method thereof.

Generally, offshore plants such as drill ship, FPSO (Floating, Production, Storage and Offloading) or vessels that need to stay in the sea for a long time should operate helicopter , Which necessitates the installation of Helideck on the player or stern.

The helideck may be comprised of a pancake portion forming a deck floor where the helicopter takes off and landing and a pancake support portion supporting the pancake portion. The pancake part may be formed by connecting a plurality of plank to each other so as to support the helicopter. The pancake support may include H-shaped beams capable of supporting the pancake portion.

For example, the pancake portion may be formed by connecting a plurality of flank of aluminum material extending in one direction. Further, the pancake supporting portion includes a plurality of aluminum H beams extending long in a direction intersecting the extending direction of the flanks and disposed below the flanks to support the pancake portion, an aluminum H beam extending long in a direction intersecting the extending direction of the aluminum H beam, And a plurality of steel H beams disposed below the beam to support the aluminum H beam.

On the other hand, the helicopter is affected by the wind very much, and unlike the pilot 's intention during take - off and landing, unexpected accident can occur. Especially, when the helicopter takes off and land on a heli-deck operated under the sea condition where the waves hit, the risk of accidents increases greatly.

If an accident occurs when a helicopter landing or landing on the helideck, the helideck may be fired by oil spilled from the helicopter or helicopter. In this case, the fire should be suppressed as soon as possible to ensure the safety of the pilot and to prevent explosions or fire from moving to floating structures or ships.

For this purpose, a plurality of sprinklers for suppressing the fire can be installed in the pancake part. The sprinkler can be installed in such a manner that the upper surface of the pancake portion, that is, the take-off and landing surface is divided into a plurality of sectors and an appropriate number is arranged in each sector, and a nozzle for spraying droplets (clear water, seawater, foam, etc.) can do. At this time, the nozzle is installed in an exposed state on the upper part of the pancake part for smooth injection of droplets.

When a fire occurs on the heli-deck, a signal or operation of the landing man- ager near the control tower or heli-deck can cause a plurality of sprinklers to simultaneously spray droplets through the nozzles to extinguish the fire.

Since the nozzle of the sprinkler is installed on the upper surface of the pancake part, it may collide with the wheel or the skid of the helicopter when the helicopter landing. Since the impact caused by helicopter landing is tens of tons or more, when the sprinkler directly collides with the wheel or skid of the helicopter, there is a great risk of breakage or failure due to the impact.

In particular, when a helicopter crashes and some sprinklers are broken or broken, and a fire occurs in a helicopter, there is a problem that the fire can not be suppressed quickly due to breakage of the sprinkler.

Alternatively, the breakage detection unit 130 may be a flowmeter installed in the middle of a flow path (not shown) for supplying the fire-fighting medium to the injection nozzle of the fire extinguishing unit 110, and the injection of the fire- The flow rate of the fire-fighting medium may rapidly increase in the flow path, and the failure detector 130 may detect a malfunction by measuring the flow rate of the fire-fighting medium.

However, the present invention is not limited thereto. The breakage detection unit 130 may be provided separately to each of the fire extinguishing units 110 and may be included in the control unit 140, Any of the general configurations capable of effectively detecting malfunctions can be employed.

The control unit 140 can receive the detection signals from the fire sensing unit 120 and the breakage sensing unit 130 and can control the fire extinguishing unit 110 based on the detection signals. The control unit 140 may be a small built-in computer, for example, and may include a program, a memory, and a data processing unit including a CPU. The program receives a detection signal from the fire detection unit 120 and the damage detection unit 130 and identifies the fire extinguishing unit 110 based on the detection signal and determines the location of each fire extinguishing unit 110 and the fire extinguishing unit And an algorithm for controlling the fire extinguishing unit 110 such as controlling the injection pressure of the fire extinguisher 110. The program may be stored in a memory unit 150 such as a computer storage medium such as a flexible disk, a compact disk, a hard disk, and an MO (magneto-optical disk), and installed in the control unit 140. In addition, the control unit 140 can independently control the plurality of fire extinguishers 110. A specific method of controlling the fire extinguisher 110 in the control unit 140 will be described later.

The memory unit 150 is connected to the control unit 140 and stores information about the unique code for identifying the location of each fire extinguisher 110 and the distance of the fire extinguishing unit of the fire extinguishing unit 110 according to the injection pressure of the fire extinguisher 110 . The control unit 140 may control the fire extinguishing unit 110 through a process of collating the information stored in the memory unit 150 with the sensing signal received from the fire sensing unit 120 and the breakage sensing unit 130. [

Hereinafter, a specific control method of the fire fighting apparatus 100 having the above-described configuration will be described with reference to the drawings.

FIG. 4 is a flowchart for explaining a process of controlling a fire by controlling the fire fighting apparatus of FIG. 1. FIG.

When the wheel or skid of the helicopter collides with the fire extinguishing unit 110 due to collision of the helicopter or the like, a fire occurs in the helicopter, and at the same time, the injection nozzle of the fire extinguishing unit 110 is damaged ≪ / RTI > The damaged fire extinguishing unit 110 may be a single or multiple fire extinguishing units, and it is assumed that the injection nozzles of the fire extinguishing unit 110 included in the accident area 20 shown in FIG. 1 are damaged due to collision with the helicopter.

When a fire occurs in the helicopter landing in the accident area 20, the control unit 140 controls the fire extinguishing unit 110 according to the flowchart of FIG. 4 to suppress the fire.

Referring to FIG. 4, the fire detection unit 120 detects a fire and transmits a fire detection signal to the control unit 140 (S10). At this time, in addition to the fire detection signal, the location information about the point where the fire occurred can be transmitted.

When a fire detection signal is transmitted to the control unit 140, the fire extinguisher 110 close to the point where the fire occurred can be operated to suppress the fire. However, if all the injection nozzles of the fire extinguishing unit 110 in the accident area 20 are damaged due to the collision with the helicopter as described above, the injection nozzle malfunctions and the malfunction of the injection nozzle is detected by the failure detecting unit 130 And transmits a breakage detection signal to the control unit 140 (S20). At this time, the damage detection unit 130 can transmit the unique code or the location information of the fire extinguishing unit 110 that has caused the malfunction.

The control unit 140 receiving the signal from the damage detection unit 130 collects information on the unique code and the position of the fire extinguishing unit 110 stored in the memory unit 150, It is possible to identify the location of the damaged fire extinguishing unit 110 against the information contained in the received damage detection signal. If the location of the damaged fire extinguishing unit 110 is identified, the controller 140 may collect the location information of the fire extinguishing units 110 located in the vicinity of the destroyed fire extinguishing unit 110 from the memory unit 150 S30).

When the location information of the neighboring fire extinguishing unit 110 is collected, the control unit 140 may calculate the distance between the fire extinguishing units 110 and the fire extinguishing unit 110 at step S40.

The control unit 140 can group the fire extinguishers 110 according to the calculated distances (S50), and fire the fire extinguishers 110 110) (S60).

Specifically, it is possible to determine whether or not each fire extinguisher 110 is located within a first distance D1 from the fire extinguisher 110. At this time, the fire extinguishers 110 located within the first distance D1 from the damaged fire extinguisher 110 may be classified as the first group 30. [

It is possible to judge whether or not the fire extinguishers 110 not classified as the first group 30 are located within the second distance D2 from the broken fire extinguisher 110, The fire extinguishers 110 may be classified into the second group 40. Also, the fire extinguishers 110 that do not belong to both the first group 30 and the second group 40 can be classified into the third group.

When the digestion unit 110 is classified into the first group 30 to the third group in this way, the digestion unit 110 belonging to the first group 30 is in a range of not less than the reference range C1 but not more than the maximum range C2 The spraying distance may be adjusted so that the fire-fighting medium is sprayed into the spraying medium. Also, it can be precisely controlled so that the fire-fighting medium can be accurately reached at the point of fire occurrence. The fire extinguishing unit 110 belonging to the second group 40 can control the injection nozzle so that the fire extinguishing medium can be injected in the maximum range C2 and the fire extinguishing unit 110 belonging to the third group can be controlled .

However, such a control method is merely an example, and the spirit of the present invention is not limited thereto. For example, the fire extinguishing unit 110 belonging to the third group may be controlled to operate, and a method of dividing the grouping into more groups than the three groups is also possible. In addition to the reference range C1 and the maximum range C2, It is also possible to set the injection range with a large number of criteria, and it is also possible to use a method that is controlled by other criteria than the distance.

According to the fire fighting apparatus and the control method of the present embodiment having the above-described configuration, even if a part of the fire extinguishing unit 110 is broken due to collision of the helicopter or the like, the area of the fire extinguishing unit 110, The fire extinguisher can be covered by the fire extinguisher 110, so that the fire can be suppressed safely, quickly, and efficiently.
