Embodiment
By the technology contents, the structural feature that specify the utility model, realized purpose and effect, know clearly below in conjunction with execution mode and conjunction with figs. and give explanation.
See also Fig. 1; The utility model provides a kind of marine vessel power line carrierband network constructing system; For realizing boats and ships broadband network and Internet connection, the utility model comprises router one, electric power bridge storage 2, electric power repeater 6 and coupler 3-5, and router one receives the external network signal; Send electric power bridge storage 2 to; Electric power bridge storage 2 is through in the high-frequency carrier signal loading and power line 12 of coupler 3 with carrying information, and electric power repeater 6 receives high-frequency carrier signal and plays the signal amplification and the effect of signal emission from power line through coupler 4, and electric power modem 7 is connected with power line; With sending on the subscriber equipment 8 after the high-frequency carrier signal demodulation, thus the transmission of the information of realization.
See also Fig. 2; Below in conjunction with the application of the utility model on boats and ships a kind of specific embodiment is provided; Present embodiment is to router one network signal to be provided by operator or bank base net network signal transmitter; In total cabinet 11 positions of bank basigamy electricity an electric power bridge storage 2 is set; This electric power bridge storage will be modulated into the high-frequency wideband carrier signal from the network signal that router one provides, and this bandwidth carrier signal is loaded into the top layer of power line 12 to high-frequency signal through coupler 3, with electromagnetic field is transferred to the total cabinet 9 of ship power distribution.The total cabinet 11 of this bank basigamy electricity connects cabinet 10 to total cabinet 9 power supplies of ship power distribution through bank base-shipboard cable.
In concrete the application; Also dispose a bank base-shipboard cable in the total cabinet 9 of ship power distribution and connect cabinet 10; This bank base-shipboard cable connects the effect that cabinet 10 plays bidirectional switch; When boats and ships pulled in to shore, bank base-shipboard cable connects cabinet 10 made the total cabinet 9 of ship power distribution be connected with the total cabinet 11 of bank basigamy electricity, thereby makes the total cabinet of bank basigamy electricity to total cabinet 9 power supplies of ship power distribution; In the boats and ships offshore, bank base-shipboard cable connects cabinet 10 makes the total cabinet 9 of ship power distribution be connected with marine generator, and marine generator is connected to the total cabinet 9 of ship power distribution.
Because the bandwidth carrier signal can produce bigger decay in the transmission course on power line; Influence the communication effect of broadband power line in the cabin; Therefore in order to remedy this signal attenuation; The technical scheme that the utility model adopts is an electric power repeater 6 to be set and to be connected in the front end that bank base-shipboard cable connects cabinet 10 through a coupler 4, and the front end of so-called circuit is meant that bank base-shipboard cable connects the front end circuit of the input of cabinet 10.The bandwidth carrier signal that electric power repeater 6 receives on the power line 12 through coupler 4; Simultaneously with being transferred on the boats and ships cable with the mode of bandwidth carrier signal once more after this bandwidth carrier signal restoring; In the present embodiment, consider that the wire laying mode of boats and ships cable and space are limited, the other end of repeater is connected with coupler 5; This coupler 5 is a power adapter; Power adapter is a capacitive coupling equipment, and it adopts the power line output of the total cabinet 9 of capacity coupled mode and ship power distribution to be connected, and its effect is the same with the coupling magnet ring.Power adapter 5 is connected with the total cabinet 9 of ship power distribution, the output signal on the electric power repeater 6 is coupled on the boats and ships cable of the total cabinet of ship power distribution.Here said electric power repeater 6 does not limit and uses one, but can a plurality of electric power repeaters 6 be set according to the power distribution architecture of boats and ships and the length of cable, to reach best communication efficiency.
As preferably; The electric power repeater 6 of present embodiment is provided with a network interface, and this network interface is connected with a wireless network receiving equipment 13, and this wireless network receiving equipment 13 can be a wireless aps; Also can be other mobile network's receiving equipments, like handheld terminals such as mobile phones.Adopt a wireless aps to be connected in the present embodiment, play wireless route, be used for receiving wireless wifi network signal, and be connected through the network interface of ethernet line with electric power repeater 6 with the network interface of electric power repeater 6.Above-mentioned wifi signal is provided by wireless signal transmission equipment on the bank, and the broadband network of 3G perhaps is provided by operator.Adopt this technical scheme, just can make boats and ships under the state of offshore or navigation, reach the purpose of boats and ships and Internet connection, also can make bank base personnel that the data and the information of equipment in the boats and ships local area network (LAN) are provided simultaneously.
In actual use; The electric power modem 7 in each cabin of boats and ships is connected with the mains, and when boats and ships moved, electric power modem 7 was connected with subscriber equipment 8; This subscriber equipment is meant IP transducer, Network Video Surveillance equipment or other electronic equipments that need communicate by letter etc.; For example, in work chamber, just can pass through electric power modem 7 connection management Surveillance center, ship-handling is monitored; At equipment compartment, IP transducer and Network Video Surveillance carry out online work information monitoring through electric power modem 7 network that is connected to other cabins in the cabin; At accommodation, IP phone or PC are connected to network through electric power modem 7.Certainly; Present embodiment does not limit and uses an electric power modem 7, but corresponding with it electric power modem 7 of each user's 11 equipment disposition, like this; Just can realize the local area network communication of boats and ships, constitute marine vessel power line carrierband network constructing system.As preferably; The subscriber equipment 8 of the utility model can be to be connected through the network interface of ethernet line with electric power modem 7; Also can adopt another kind of electric power modem 7, this electric power modem 7 can be launched the network signal that electric power modem 7 demodulation are come out from the band signal transmission cards with the form of wireless signal; User side receives the network signal of electric power modem 7 emissions through wireless network card, connects thereby reach communication.
