Comprising a processing device installed in the lower chamber, and a console at least one of input and output devices of the processing unit installed in the upper chamber is mounted, the processing unit and the input device The partition floor plate is characterized in that at least one wiring hole through which a cable for connecting the cable and a cable for connecting the arithmetic processing device and the output device are passed.

According to the steering room structure of the ship, the input device and the output device are installed in the upper chamber, and the arithmetic processing device connected to the input device and the output device is installed in the lower chamber. That is, the arithmetic processing unit housed in the cabinet in the conventional console is installed in the lower chamber. Therefore, the input device and the output device, which are usually installed in the upper room where the operator is, are downsized as compared with the conventional cabinet type console. That is, it is possible to simplify the devices installed in the operation space (that is, the upper chamber) of the steering room without reducing the number of devices provided in the steering room. As a result, the operator's operation space in the steering room is expanded, and operability can be improved. In addition, it is possible to reduce the floor area of the steering room while securing an operation space for an operator, which is the same as the conventional one.

Further, in the steering room structure of the above-mentioned ship, a cable connecting the arithmetic processing device and the input device and a cable connecting the arithmetic processing device and the output device are inserted into the wiring hole of the partition floor plate. No fire protection is required. As a result, it is possible to reduce the labor and cost involved in the cable wiring work.

In the steering room structure of the ship, the height of the lower chamber may be 900 mm or more and less than 2000. The height of the lower chamber is the vertical distance from the upper surface of the floor of the steering room to the lower surface of the partition floor plate.

As a result, a sufficient room height is ensured for operators and workers to perform inspection and construction work in the lower room.

In the steering room structure of the above-mentioned ship, the partition floor plate may be provided with a transparent portion for visually recognizing the lower chamber from the upper chamber.

Thereby, the operator or the worker can visually recognize the state of the arithmetic processing device installed in the lower chamber from the upper chamber through the transmitting portion without moving to the lower chamber.

In the steering room structure of the above-described ship, the partition floor plate may be provided with an inspection port for visually recognizing the lower chamber from the upper chamber.

As a result, the operator or the operator can visually check the state of the arithmetic processing unit installed in the lower chamber through the inspection port without moving to the lower chamber.

In the steering room structure of the ship, the partition floor plate may be provided with an access hatch for a person to access the lower room from the upper room.

This allows an operator or worker to move between the upper and lower chambers through the access hatch.

The steering room structure of the ship may include an air conditioner that independently air-conditions the upper chamber and the lower chamber.

As a result, the lower chamber in which the arithmetic processing unit that generates heat is arranged and the upper chamber, which is the operation space for the operator, can be adjusted to the temperature and humidity environment according to the purpose.

The wheelhouse structure of the ship may include a fire alarm in each of the upper chamber and the lower chamber.

Thereby, even if a fire occurs in either the upper chamber or the lower chamber, the fire is promptly notified.

The wheelhouse structure of the ship may include an automatic diffusion type fire extinguisher in the lower chamber.

As a result, when a fire occurs in the lower chamber, the automatic diffusion type fire extinguisher provides a quick initial fire extinguishing.

In the steering room structure of the ship, a plurality of pillar members supporting the partition floor plate may be provided upright on the floor of the steering room, and the arithmetic processing device may be attached to the pillar members.

In this way, since the pillar member for supporting the partition floor plate also has the function of supporting the arithmetic processing device, the supporting member only for the arithmetic processing device can be omitted. Therefore, it is possible to secure a working space for an operator or a worker while securing a wiring space and a space for arranging devices such as an arithmetic processing unit in the lower chamber.

FIG. 1 is a schematic sectional view of a steering room 2 of the ship 1 and its surroundings, showing a steering room structure of the ship 1 according to an embodiment of the present invention. FIG. 1 shows a steering room 2 provided in the ship 1 and a cabin 9 arranged immediately below the steering room 2. The cabin 9 may be a cargo room or a machine room.

A steering room 2, which is a space surrounded by windows, partition walls, upper and lower decks, etc., is formed in the ship 1. The floor 20 (deck) of the steering room 2 is formed by squeezing steel plates and is heat-insulated by a non-combustible material or a non-combustible sealing material. The non-combustible material may be, for example, one or more of glass fiber, ceramic fiber, rock wool and the like. The floor 20 of the wheelhouse 2 has a fireproof structure that complies with the fireproof standard (A60 class partition) of the bulkhead and deck between the control location of the SOLAS convention and the adjacent location.

Although not shown, the ceiling of the steering room 2 and the partition wall that separates the steering room 2 from the surrounding cabin are also formed of steel plates and have a predetermined heat insulating process. That is, the wheelhouse 2 is provided with a partition wall between the control location of the SOLAS convention and an adjacent location and a fireproof structure that complies with the fireproof standard (A60 class partition) of the deck.

(4) A partition formed by a bulkhead or deck that meets the requirements of (4) being capable of blocking the passage of smoke and flame until the end of the 60-minute standard fire test.

A partition floor plate 3 is laid above the floor 20 of the steering room 2 at a predetermined interval in the vertical direction from the floor 20. The partition floor plate 3 divides the steering chamber 2 into two spaces, an upper chamber 21 and a lower chamber 22, which are upper and lower spaces. The upper surface of the floor 20 of the steering room 2 and the upper surface of the partition floor plate 3 are parallel to each other. Further, the vertical distance from the upper surface of the floor 20 of the steering room 2 to the lower surface of the partition floor plate 3, that is, the height H of the lower room 22 is 900 mm or more and less than 2000 mm. If the height of the lower chamber 22 is 900 mm or more, a sufficient indoor height is secured for the operator or the worker to perform inspection or construction work in the lower chamber 22. However, if the height H of the lower chamber 22 is excessively increased, the height of the steering chamber 2 is excessively increased. Therefore, the height H of the lower chamber 22 is such that an operator or a worker can bend or sit to work. It is desirable to keep the height.

FIG. 2 is a diagram showing a support structure for the partition floor plate 3. As shown in FIG. 2, the partition floor plate 3 is placed on a frame 30 standing on the floor 20 of the steering room 2. The frame 30 is composed of a plurality of columns 31 standing on the floor 20 of the steering room 2 and beams 32 connecting the columns 31 to each other.

The partition floorboard 3 may be made of, for example, one or more materials selected from a wooden board, a wooden or resin panel, a thin steel plate, and the like. The partition floor plate 3 is not a structural member defined by the structural member of the ship 1, but may have a strength that can support the load of the equipment or operator placed on the partition floor plate 3. Further, although it is desirable that the partition floor plate 3 is made of a non-combustible material, it is necessary to comply with the requirements for smoke and flame passage and the temperature rise limit required for the A class partition and the B class partition. I don't need it.

The partition floor plate 3 is provided with an access hatch 38 for allowing an operator or a worker to access from the upper chamber 21 to the lower chamber 22 or vice versa. A plurality of access hatches 38 may be provided in one steering room 2. The access hatch 38 is an elevating port provided with the opening/closing lid 33.

In the steering room 2 of the boat 1 having the above-described configuration, the lower room 22 is provided with a processing device 51 and a power supply device, and the upper room 21 is provided with a console 50 equipped with at least one of an output device 52 and an input device 53. is set up. The output device 52 is means for outputting information from the arithmetic processing device 51, and has an information transmission function and/or a situation presentation function. The input device 53 is a means for inputting commands and information to the arithmetic processing device 51, and has a function of adjusting various situations of the ship 1. The devices mounted on the console 50 are not limited to the above, and for example, communication devices may be mounted.

It should be noted that FIG. 1 shows one console 50 included in the navigation and control workstations in the steering room 2 and a processor 51 corresponding thereto, but a plurality of consoles 50 are provided in the steering room 2. It may be provided. In the wheelhouse 2, in addition to voyage and control workstations, berthing work workstations, surveillance and auxiliary voyage workstations, workstations related to safety, voyage planning workstations, etc. are provided, but each workstation has one or more consoles. May be provided. Each console is equipped with equipment and instruments according to the function of the workstation.

The console 50 has a substantially horizontal operation console, and the input device 53 is provided on the operation console. Further, the output device 52 is arranged at the end of the line of sight of the operator who faces the console in the console 50.

The output device 52 mounted on the console 50 may be, for example, at least one of a display, a touch panel, an alarm lamp, and an alarm device. Further, the output device 52 mounted on the console 50 may include a display unit of various instruments such as a gyro compass and a GPS device. For example, various consoles such as an engine monitor, a long range radar, a screen of a bridge information unit, a screen of an electronic chart unit and a short range radar may be mounted on the console of a navigation and control workstation.

The input device 53 mounted on the console 50 may be, for example, at least one of a keyboard, a lever, a joystick, a button, a switch, a dial, and a touch panel. For example, the navigation and control workstation console includes an operation unit including an autopilot dial of the bridge information unit, an engine telegraph, a thruster dial, a joystick lever, a whistle switch, a steering wheel, an inboard telephone, an operation panel of an electronic chart unit, Various input devices 53 such as a navigation light and a whistle control panel, a thruster and a steering control panel may be mounted.

The arithmetic processing unit 51 and the output unit 52 are electrically connected (that is, capable of transmitting and receiving signals) by a communication cable. Then, the output signal from the arithmetic processing device 51 is output from the output device 52. Similarly, the arithmetic processing unit 51 and the input unit 53 are electrically connected by a communication cable. Then, a signal including a command and information input from the input device 53 is input to the arithmetic processing device 51. Further, an electric power supply cable for supplying electricity from an unillustrated inboard power supply is connected to the arithmetic processing device 51, the output device 52, and the input device 53. Below, a communication cable, an electricity supply cable, etc. are called cables 60.

The partition floor plate 3 is provided with a wiring hole 55 through which the cables 60 are passed. The wiring hole 55 penetrates the partition floor plate 3. In order to conceal the wiring hole 55 from the steering room 2 and improve the appearance, the wiring hole 55 may be provided in the partition floor plate 3 below the leg of the console 50 or in the vicinity thereof.

Since the partition floor plate 3 does not correspond to a partition wall and a deck between the control place and the adjacent place, the conventional fireproofing of the penetration part is unnecessary. This conventional fireproofing of the through portion is, for example, filling a fireproof sealing material between the combing forming the through portion and the cables 60, and further covering the through portion with a heat insulating plate material.

It is desirable that the arithmetic processing unit 51 be provided immediately below the wiring hole 55 in order to shorten the length of the cables 60 and facilitate wiring. The arithmetic processing unit 51 is attached to the frame 30 for supporting the partition floorboard 3. In the present embodiment, a device base 37 is provided so as to straddle a plurality of columns 31 that form the frame 30, and the arithmetic processing device 51 is fixed to the device base 37. In this way, since the columns 31 (column members) for supporting the partition floor plate 3 also have the function of supporting the arithmetic processing device 51, a supporting member only for the arithmetic processing device 51 can be omitted. it can. As a result, it is possible to secure a working space for the operator or the worker while securing a wiring space and a space for disposing devices such as the arithmetic processing device 51 in the lower chamber 22.

The frame 30 may be provided with a cable hanger 39. The cable hanger 39 is for guiding and holding the cables 60 laid in the lower chamber 22. Here, the cable hanger 39 may be provided on the upper portion of the frame 30. As a result, ducts or pipes (not shown) can be laid under the cables 60, and interference between the ducts or pipes and the cables 60 can be avoided. Further, in the limited space of the lower chamber 22, ducts, pipes, cables 60, the arithmetic processing device 51, etc. can be arranged in an orderly manner.

As described above, in the structure of the steering room 2 of the boat 1 according to the present embodiment, the arithmetic processing unit 51 housed in the cabinet of the conventional console is installed in the lower room 22 and installed in the upper room 21. An input device 53 and an output device 52 are mounted on the console 50. Therefore, the console 50 according to the present embodiment is smaller than the conventional cabinet-integrated console. By downsizing the console 50, the operator's operation space in the steering room 2 can be expanded and the operability of the steering room 2 can be improved. In addition, it is possible to reduce the floor area of the steering room 2 while securing an operator's operation space equivalent to the conventional one. Further, by adopting the downsized console 50, the degree of freedom in layout of each device in the steering room 2 is increased as compared with the conventional steering room 2.

The number of alarm devices provided in the console 50 may be reduced in order to further reduce the size of the console 50. In this case, the console 50 is provided with a small number of representative alarm devices, and the lower chamber 22 is provided with individual alarm devices indicating the specific contents of the alarm. A typical alarm device is an alarm device for informing the operator of the presence or absence of a defect when some defect occurs.

Each alarm device is installed in the housing of the arithmetic processing unit 51 arranged in the lower chamber 22 or in the vicinity thereof, and outputs a warning upon receiving a signal from the arithmetic processing unit 51 and other instruments. Here, the representative alarm device may be at least one of an alarm lamp and an alarm speaker, and the individual alarm device may be an alarm lamp or the like. When the arithmetic processing unit 51 detects a defect, it outputs an alarm from both a typical alarm device and individual alarm devices. Then, the operator who is informed of the malfunction by the representative alarm device can visually recognize the individual alarm devices installed in the upper chamber 21 to the lower chamber 22 to know the specific content of the alarm. ..

A transparent portion 35 may be provided on at least a part of the partition floor plate 3 so that an operator can visually recognize various devices including the processing unit 51 and the alarm device installed in the upper chamber 21 to the lower chamber 22. The transparent portion 35 of the partition floor plate 3 is formed of a transparent material that forms the same plane as the surrounding partition floor plate 3 and is transparent to the interior of the upper chamber 21 to the lower chamber 22. As the transparent material, for example, a plate material such as tempered glass or polycarbonate having a strength capable of withstanding the load of the operator is adopted.

Further, in place of or in addition to the transmission part 35, the partition floor plate 3 may be provided with an inspection port 36 for visually recognizing the inside of the upper chamber 21 from the lower chamber 22. The inspection port 36 is an opening through which an operator looks into the lower chamber 22 from the upper chamber 21 or inserts his/her hand to perform work. The inspection port 36 may be provided with a transparent or opaque lid.

As described above, through the transparent portion 35 and/or the inspection port 36 of the partition floor plate 3, the operator or the operator can visually check the status of various devices installed in the lower chamber 22 without moving to the lower chamber 22. it can. Then, if necessary, the operator or the worker can move from the upper chamber 21 to the lower chamber 22 through the access hatch 38 to perform maintenance of various devices.

Fire alarms 41 and 42 are provided in each of the upper chamber 21 and the lower chamber 22 of the steering room 2. As a result, even if a fire occurs in either the upper chamber 21 or the lower chamber 22, the operator or the seafarer is immediately notified of the fire. In the conventional underfloor wiring structure, it is not obligatory to install a fire alarm in the underfloor wiring space.

The lower chamber 22 of the steering room 2 is provided with an automatic diffusion type fire extinguisher 43. The automatic diffusion type fire extinguisher 43 is configured to react with heat and explode by itself when the environmental temperature exceeds a predetermined temperature to dissipate the powder fire extinguishing agent. In this way, by providing the lower chamber 22 with the fire extinguisher that automatically detects the temperature rise due to the fire and disperses the powder fire extinguishing agent, quick initial fire extinguishing can be performed. In the conventional underfloor wiring structure, no fire extinguisher is required to be installed in the underfloor wiring space.

Further, the steering room 2 is provided with an air conditioner that independently air-conditions the upper chamber 21 and the lower chamber 22. That is, indoor units 56 and 57 of an air conditioner are provided in each of the upper chamber 21 and the lower chamber 22. The number of outdoor units corresponding to these indoor units 56, 57 may be one, or an outdoor unit may be provided corresponding to each of these indoor units 56, 57. By providing such an air conditioner, each of the lower chamber 22 in which various devices including the heat-generating arithmetic processing device 51 are arranged and the upper chamber 21 which is an operation space are adjusted to an appropriate temperature and humidity environment. can do.
