The plurality of firewalls 11 to 14 refer to a criterion for dividing an entire ship into a predetermined MFZ (Maximum Fire Zone) region. In the present invention, the entire ship is divided into five MFZ (MFZ0 to MFZ4) regions. Here, the number of MFZ zones is preferably set appropriately according to the size of the ship.

The plurality of internal high frequency (UHF) antenna cables 21 to 24 are respectively installed in a plurality of MFZ (Maximum Fire Zone) zones defined on the basis of the firewalls 11 to 14, do.

The radio signal distributors 31 to 34 transmit the radio signals transmitted in the MFZ region different from the transmission of the radio signals received through the internal UHF antenna cables 21 to 24 to the internal UHF antenna cables 21 to 24 . Here, since the configuration and operation of the plurality of radio signal distributors 31 to 34 are the same, only one radio signal distributor 31 will be described below for convenience of explanation.

2 and 3, the radio signal distributor 31 includes a cabinet 31b provided on a handrail 81 installed on a deck and having a distributor 31a for distributing radio signals. A guide line pipe 31c installed in a vertical direction of the cabinet 31b to guide the inner UHF antenna cable 21 to the MFZ zone MFZ4; A radio signal generated in the MFZ zone connected to the distributor 31a built in the cabinet 31b is transmitted to the radio signal repeater 40 and the radio signal transmitted from the radio signal repeater 40 is received And an external UHF antenna cable 31d. Here, the external UHF antenna cable 31d is preferably installed inside the cable protection cable pipe 82. The cabinet 31b is provided with a handle 31e for opening and closing the door.

The radio signal repeater 40 receives and amplifies the radio signal obtained by the radio signal distributor 31, and propagates the amplified radio signal to the plurality of MFZ regions.

In each MFZ area, install an internal UHF antenna cable (21 ~ 24) along the cable tray to install various cables required in the MFZ area. That is, the internal UHF antenna cables 21 to 24 are installed in the same manner as a cable installation method using a cable tray installed in each MFZ area.

In a case of intending to communicate with a person in another MFZ zone in a specific MFZ zone (for example, MFZ4) during intra-board communication, the UHF band radio signal generated in the MFZ4 zone is received through the internal UHF antenna cable 21, And is transmitted to the signal distributor 31.

Here, the wireless signal distributor 31 is mounted on the handrail 81 installed on the deck, which is the uppermost part of the ship, using U-bolts or the like.

And is also connected between the radio signal repeater 40 and the radio signal distributor 31 through the UHF antenna cable 31d. At this time, in order to protect the UHF antenna cable 31d, it is preferable to embed the UHF antenna cable 31d in the cable protection cable pipe 82. [

The radio signal repeater 40, which receives the UHF band radio signal transmitted from the radio signal distributor 31 through the UHF antenna cable 31d, amplifies the received signal and supplies the amplified signal to the UHF antenna cable 31d to the MFZ zone. Here, the wireless signal repeater 40 amplifies the wireless signal received from the wireless signal distributor 31, and transmits the amplified wireless signal to the specific wireless signal distributor to transmit the wireless signal to only the MFZ area managed by the specific wireless signal distributor. Alternatively, the RF signal received from the MFZ 4 region may be transmitted to all MFZ regions by amplifying the RF signal received from the RF signal distributor 31 and transmitting the amplified RF signal to all the RF signal distributors. In the present invention, it is assumed that a radio signal received in a specific MFZ region is transmitted to all MFZ regions.

The radio signal in the UHF band transmitted from the radio signal repeater 40 is received by a radio signal distributor controlling each MFZ zone installed on the deck, and the radio signal distributor transmits a radio signal received through an internal UHF antenna cable connected thereto , And allows a person in the MFZ zone to receive a radio signal transmitted from another MFZ zone.

By implementing a communication converter for on-board broadcasting and transmitting / receiving UHF band radio signals on the basis of the above-described principle, even when a specific MFZ area is burned, communication can be performed using radio signals of UHF band between different MFZ areas .

On the other hand, when the radio signal distributor 31 receives the radio signal transmitted from the other MFZ region from the radio signal repeater 40, the radio signal distributor 31 transmits the radio signal through the connected internal UHF antenna cable 21, So that the signal transmitted from the area can be received.

Here, the wireless signal may be a voice signal for communication between people, and may be a voice signal for warning broadcasting or announcement broadcasting.

The present invention is also characterized in that, as another feature, the unmanned telephone set 50 is provided in a part of the MFZ area of the entire ship (for example, the MFZ3 area), and the telephone communication with the other MFZ area or the control room is also possible Do.

In another aspect of the present invention, an automatic telephone set 60 is provided in a part of the MFZ area of the entire ship (for example, MFZ2 area), and automatic dialing and telephone conversation with the other MFZ area or the control room It is also possible.

Further, as another feature of the present invention, an advanced broadcasting system 71 (72) for in-ship broadcasting is provided in some areas (for example, MFZ3 and MFZ1) of the MFZ area of the ship , So that it is possible to perform on-board broadcasting in a wired manner. Here, the Public Address System is a known system for amplifying or controlling sound in a large room or in front of a large audience. Usually, it is implemented using a plurality of microphones, a power amplifier, a speaker, and the like.

Although the present invention has been described in detail with reference to the above embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.

The present invention is applied to communication equipment technology for wirelessly communicating between different MFZ zones even when a specific MFZ zone is burned in a ship.
