Accordingly, any embodiment described in the Detailed Description of the Invention is illustrative for a better understanding of the invention and is not intended to limit the scope of the invention to embodiments.

The functional blocks shown in the drawings and described below are merely examples of possible implementations. In other implementations, other functional blocks may be used without departing from the spirit and scope of the following detailed description. Also, although one or more functional blocks of the present invention are represented as discrete blocks, one or more of the functional blocks of the present invention may be a combination of various hardware and software configurations that perform the same function.

In addition, the expression "including any element" is merely an expression of an open-ended expression, and is not to be construed as excluding the additional elements.

Further, when a component is referred to as being connected or connected to another component, it may be directly connected or connected to the other component, but it should be understood that there may be other components in between.

First, a schematic structure of a network system according to the present invention will be described with reference to FIG.

FIG. 1 shows a worksite in which a ship or an offshore plant is being constructed or constructed, and a network system including the composite cable 100 and the multi-connector 200 is implemented in the work site.

First, the composite cable 100 refers to a cable including the telephone cable 110 and the power cable 120 at the same time. As shown in FIG. 1, the distribution cable 100 is a communication signal received from outside through a data communication cable and an electric cable And power to the worksite with one composite cable (100).

The composite cable 100 is for providing communication signals and power to a communication terminal installed in various places in a ship or an offshore plant operation site, typically an AP terminal 300 or a telephone, It is expected to make a great contribution to improving the environment that could not be achieved at all.

On the other hand, the hybrid cable 100 is characterized by simultaneously transmitting a communication signal and power. In the case of constructing a network system by installing only one composite cable 100 at a work site, In addition to the cost savings, the space occupied by the cable can also be greatly reduced, thereby increasing the work space.

The detailed structure of the composite cable 100 will be described in detail with reference to FIG.

Next, the offshore plant network system according to the present invention includes the multi-connector 200 as a configuration. The multi-connector 200 is basically a device that is connected to the composite cable 100. When the composite cable 100 is plugged in, it receives a communication signal and power through the composite cable 100, In particular, relaying the communication signal to another communication terminal connected to the multi-connector 200.

The multi-connector 200 referred to in the present invention is basically made of a small-sized plastic injection molding, that is, an inlet plug into which the composite cable 100 is plugged in the housing 290, a distributor for acquiring and distributing communication signals and electric power, And an outlet plug through which the cable used to transmit the distributed communication signal or power to the externally connected terminal is extended.

The multi-connector 200 having such a simple structure and not requiring a large manufacturing cost can be provided in many places in a ship or an offshore plant operation site.

In particular, the multi-connector 200 contributes greatly to the maintenance cost of the entire network system in addition to the composite cable 100. At the work site, many workers are moved or the fixture is moved, and the cable is broken or the cover 150 is peeled off during the movement of the work tools. In such a case, cable damage frequently occurs. May lead to an electric power supply required for the operation, or may indirectly cause a short circuit or fire accident, and immediate maintenance measures are required. The composite cable 100 and the multi-connector 200 are components of a system that is very easy to replace. Even if a cable is damaged, the cable 100 and the power cable 120 need not be divided and replaced, In addition, the multi-connector 200 is also connected to the damaged portion of the composite cable 100 so that the new composite cable 100 can be extended. In addition, Ship or offshore plant.

The structure of the multi-connector 200 will be described in detail with reference to FIG.

Referring to FIG. 1, the offshore plant network system according to the present invention may further include an AP terminal 300.

The AP terminal 300 basically receives a communication signal and power, and is driven by using the received power. The received communication signal is transmitted to another communication terminal connected to the AP terminal 300, for example, a wired computer , And wirelessly connected portable terminals.

Particularly, the AP terminal 300 in the system according to the present invention is characterized in that it is connected to the composite cable 100 and receives a communication signal and power from the composite cable 100. At this time, the composite cable 100 is preferably extended from the outlet plug of the multi connector 200 and connected thereto. That is, the AP terminal 300 can receive a communication signal and power distributed from the multi-connector 200 through the composite cable 100. [

The AP terminal 300 ultimately plays an essential role in establishing a communication environment free from a shadow area in a ship or offshore plant operation site. The AP terminal 300 does not connect only the telephones in the work site By making wired or wireless data communication possible, workers can communicate with communication devices, computing devices, and portable terminals carried by workers at work sites.

The detailed configuration of the AP terminal 300 will be described in detail with reference to FIG.

With reference to FIG. 1, the components of the offshore plant network system according to the present invention, and the connection relationship between the components, have been described.

Hereinafter, the structure of each component will be described with reference to FIGS. 2 to 4. FIG.

2 shows the internal structure of the composite cable 100 in an easy-to-understand manner.

According to Fig. 2, it can be seen that the composite cable 100 comprises a power cable 120 consisting of two core power cables and one core ground cable, and a telephone cable 110 consisting of two lines have.

The power cable 120 may preferably be a single phase AC 220V cable and the telephone cable 110 may be a CPEV cable.

The CPEV cable refers to a pair of cables in a polyethylene insulated vinyl sheath. The CPEV cable is mainly used for a telephone line and a security communication line in a certain area. In addition, since the above-mentioned CPEV cable uses an insulator excellent in moisture resistance, the possibility of malfunction due to moisture is low, the withstanding voltage is high, and the parallel arrangement with the transmission and distribution lines is possible, there is no cable trouble caused by corrosion, And CPEV cables are suitable for use in a work site in consideration of the marine environment. Therefore, the CPEV cable can be used to construct a network environment by being embedded in the composite cable 100 of the present invention .

Meanwhile, since the composite cable 100 is frequently installed and demounted at the work site, the composite cable 100 is realized as a stranded structure composed of a plurality of strands of one core, thereby improving the durability of the cable .

The composite cable 100 may further include an additional protection layer such that the inner telephone cable 110 and the power cable 120 are covered with a thermoplastic elastomer (TPE) material 150. [

Meanwhile, the cover 150 surrounding the telephone cable 110 and the power cable 120 may be made of LSZH (Low Smoke Zero Halogen) material. The use of LSZH material is advantageous in that it can reduce the emission of toxic gas even if a fire occurs on the floating surface and prevent the spread of fire.

It should be understood that although the present specification refers only to the telephone cable 110 as a means for transmitting the communication signal in the composite cable 100, it is also possible to use an optical fiber as means for transmitting the communication signal. When an optical fiber is used as a means for transmitting a communication signal, not only a voice signal but also a large amount of data can be transmitted together, so that it is possible to effect more effective communication among the workers.

Next, the detailed configuration of the multi-connector 200 will be described with reference to FIG.

Referring to FIG. 3, it can be seen that the multi-connector 200 is largely composed of an inlet plug 210, a distribution portion (dotted rectangle), outlet plugs 230, 250 and 270, and a housing 290.

The multi-connector 200 includes two or more outlet plugs, which are connected to the composite cable 100 according to whether the resources supplied to the outside through the outlet plug are a communication signal, a power, a communication signal, And extracts a communication signal or electric power.

At this time, the multi-connector 200 may further include a voltage converting unit (not shown) for converting an AC voltage to a DC voltage. Since the power supplied through the composite cable 100 is based on an AC voltage, an apparatus driven only by a DC voltage may exist in the multi connector 200. Therefore, To provide an appropriate voltage, regardless of whether or not the voltage is used.

Meanwhile, the distributing unit may be configured to contact a cable with an electric wire connected to the outlet plug to extract a communication signal or electric power. Alternatively, an active circuit device, for example, an integrated circuit such as an ASIC may be provided, The communication signal and power can be extracted from the communication device 100 and managed by the manager (signal amount and power amount control).

That is, it should be understood that the distributing unit referred to in the present specification does not limit the internal implementation as long as it can extract a communication signal or power from the composite cable 100 and transmit it to each outlet plug.

Next, the outlet plug is an extended portion of the output cable 500. Here, the output cable 500 collectively refers to a communication signal, a power, or a communication signal extracted by the distribution unit and a cable through which electric power is transmitted . In particular, the output cable 500 for transmitting only the communication signal, the output cable 500 for only the power, and the output cable 500 for transmitting the communication signal and the power at the same time All of which may be of different structures.

Also, it should be understood that the plurality of outlet plugs have the same outer shape, but different resources can be transmitted according to the type of output cable connected to the plug. 3, the first outlet plug 230 may include a connection pin 215 connected to the power cable so as to output only power, and the third outlet plug 270 may include a power and communication signal And a connection pin 215 connected to the composite cable 100 (the power cable 120 and the telephone cable 110) so as to be capable of outputting all of the signals.

In this way, the multi-connector 200 can include a plurality of outlet plugs, each outlet plug having an output cable 500 for transmitting only communication signals, an output cable 500 for transmitting only power, And can be connected to the output cable 500 transmitting at the same time.

Referring to FIG. 3, the illustrated multi-connector 200 includes three outlet plugs. For the sake of convenience, the first outlet plug 230 outputs only power The second outlet plug 250 and the third outlet plug 270 are implemented to output communication signals and power.

As described above, the multi-connector 200 may include a plurality of outlet plugs, and each outlet plug may separately provide the communication signal and power extracted from the composite cable 100, or may provide the same.

Meanwhile, the system according to the present invention may further include a status display unit, which means a display unit that displays a communication signal or a transmission status of power to a user. The status display unit may be connected to the composite cable 100 or the multi-connector 200 in an extended manner.

Next, a detailed configuration of the AP terminal 300 will be described with reference to FIG.

Referring to FIG. 4, the AP terminal 300 includes a hybrid cable connection unit 310, a power control unit 330, and a communication module.
