Description

Technical Field

[0001] The utility model relates to a system for ship signal transmission and power supply, in particular to an all-optical network system for ships. Background Art

[0002] Currently, digital networks have been popularized on ships. Regardless of the size and type of the ship, the network system has become an infrastructure of the ship. The all-optical network (AON, All Optical Network) has the characteristics that the signals transmitted only undergo the conversion of electricity / light and light / electricity when entering and leaving the network, and always exist in the form of light during the network transmission and switching process. Therefore, it has the characteristics of transmitting to network terminal devices through one optical cable, without a relay switch, long wiring distance, simple network structure, and high network resource utilization rate, which is particularly suitable for the limited space of ships. However, from the actual implementation perspective, due to the passive transmission of the all-optical network, most of the network terminal devices used on ships need to adopt the POE power supply method. Therefore, a POE (Power Over Ethernet) switch needs to be configured for the network terminal devices to achieve the POE power supply function. It can be seen that the current wiring method adopted on ships is actually a hybrid optical and electrical wiring method. Further, the cable length of the POE switch cannot exceed 100 meters. For network terminal devices more than 100 meters away from the POE switch, a relay switch needs to be additionally installed to achieve this. It can be seen that when the all-optical network is applied to ships, due to the emergence of the POE switch, the ship space becomes more tense, the wiring becomes complex, and the long-distance wiring advantage of the all-optical network is greatly reduced, and it is even inferior to the electrical network, so it needs to be solved. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an all-optical network system for ships, which realizes the transmission of signals of the all-optical network and also provides the POE power supply function through the ONU, without a POE switch, with simple wiring, enabling the ship to truly realize the all-optical network.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An all-optical network system for ships includes a network cabinet, in which a server, a core switch, an optical line terminal, and an ONU centralized power supply box are arranged. Among them: the server is connected to the optical line terminal via the core switch, the optical line terminal is connected to the optical splitters arranged on each deck of the ship, and each optical splitter is connected to the cabin ONUs and the public area ONUs on the same deck as it; the ONU centralized power supply box is connected to the ONU power distribution boxes arranged on each deck of the ship, and each ONU power distribution box is connected to the cabin ONUs and the public area ONUs on the same deck as it.

[0006] The advantages of the present utility model are as follows:

[0007] The present utility model re-integrates ship power supply and signal transmission. While realizing all-optical network signal transmission, it is equipped with an ONU with POE power supply function, getting rid of the dependence of the all-optical network on the POE switch. The wiring is simple. The server, core switch, optical line terminal, and ONU centralized power supply box are integrally arranged in the network cabinet, occupying less space and not affecting the normal use of the ship. There is no need for intermediate power access, meeting the long-distance uninterrupted signal transmission requirements of multiple cabins and multiple public areas on each deck of the ship and the power supply needs of network terminal devices that require POE power supply. The ship truly realizes an all-optical network (i.e., all signals are transmitted through optical signals), enabling the all-optical network to truly play its own advantages.

[0012] As Figure 1 shown, the present utility model provides an all-optical network system for a ship, including a network cabinet 10. Inside the network cabinet 10, there are a server 11 as a control and storage center, a core switch 12, an optical line terminal 13, and an ONU centralized power supply box 20. Among them: The server 11 is connected to the optical line terminal 13 via the core switch 12. The optical line terminal 13 is connected to the optical splitters 30 arranged on each deck of the ship. Each optical splitter 30 is connected to the cabin ONUs 40 and the public area ONUs 50 on the same deck as it; The ONU centralized power supply box 20 is connected to the ONU power distribution boxes 70 arranged on each deck of the ship. Each ONU power distribution box 70 is connected to the cabin ONUs 40 and the public area ONUs 50 on the same deck as it.

[0013] In actual implementation, the optical line terminal 13 is connected to the optical splitter 30 through an optical cable, and the optical splitter 30 is connected to each cabin ONU 40 and each public area ONU 50 on the same deck through an optical cable. Among them, the optical splitter 30 is connected to the optical signal access ports of the cabin ONU 40 and the public area ONU 50. Further, the ONU centralized power supply box 20 is connected to the ONU power distribution box 70 through a power supply cable, and the ONU power distribution box 70 is connected to each cabin ONU 40 and each public area ONU 50 on the same deck through a power supply cable. Among them, the ONU power distribution box 70 is connected to the power access ports of the cabin ONU 40 and the public area ONU 50.

[0014] In actual design, the cabin ONU 40 is provided with an RJ45 POE port and a USB port. The RJ45 POE port is used to connect network terminal devices that need to be powered in the POE mode, such as Figure 1 the shown Internet access device 61, telephone 62, IPTV (Interactive Network TV) 63, and wireless AP (Wireless Access Point) 64, etc. Similarly, the public area ONU 50 is provided with an RJ45 POE port and a USB port. The RJ45 POE port is used to connect network terminal devices that need to be powered in the POE mode, such as Figure 1 the shown wireless AP 65, monitoring probe 66, etc.

[0015] Such as Figure 4 , the figure schematically shows the cabin ONU 40, which has an optical signal access port and a power access port, and is provided with four RJ45 POE ports and a USB port. The setting of the public area ONU 50 is basically the same as that of the cabin ONU 40, so it will not be elaborated here. Please refer to Figure 4 to understand.

[0016] In actual design, the ONU centralized power supply box 20 includes an AC / DC power module 21, which is used to convert alternating current into direct current required for power supply to each deck and send it to each ONU power distribution box 70.

[0017] Such as Figure 2 , the figure exemplarily shows an ONU centralized power supply box 20, which is provided with 6 deck output ports (A, B,..., F deck output ports), and can be used to be respectively connected to the ONU power distribution boxes 70 on 6 decks.

[0018] The ONU power distribution box 70 is marked with wiring marks to each cabin and each public area for easy troubleshooting. Such as Figure 3, as shown in the figure by way of example, there is an ONU power distribution box 70. The deck where it is located is provided with 8 cabins and 8 public areas. Therefore, the ONU power distribution box 70 provides 8 cabin ports (cabin 1 port, cabin 2 port, …, cabin 8 port) and 8 public area ports (public area 1 port, public area 2 port, …, public area 8 port). The 8 cabin ports are used to connect to the power access ports of each cabin ONU 40, and the 8 public area ports are used to connect to the power access ports of each public area ONU 50.

[0019] In actual implementation, each deck is provided with an optical splitter 30 and an ONU power distribution box 70. The optical splitter 30 and the ONU power distribution box 70 on the same deck are arranged in one box to simplify wiring and save ship space.

[0020] In the present utility model, the core switch 12, the optical line terminal 13, the optical splitter 30, the ONU centralized power supply box 20, the ONU power distribution box 70, the cabin ONU 40 and the public area ONU 50 are all existing devices in the art. Among them: The core switch 12 is a switch with some router functions. The optical line terminal (OLT, Optical Line Terminal) is a terminal device for connecting to an optical fiber trunk line. The optical splitter 30 is a passive device, also known as an optical splitter, which does not require external energy and only needs input light. The ONU centralized power supply box 20 is used to supply power to all ONUs of the entire all-optical network, and the ONU power distribution box 70 is used to supply power to all ONUs on different decks. The cabin ONU 40 and the public area ONU 50 are both ONUs (Optical Network Unit), which are terminal devices for fiber optic access and are used in cooperation with the OLT.

[0021] POE (Power Over Ethernet) is a technology that, without any modification to the existing Ethernet Cat.5 cabling infrastructure, can transmit data signals to some IP-based terminals (such as IP telephones, wireless local area network access points AP, network cameras, etc.) and at the same time provide DC power supply for such devices. POE is also called Power over LAN (POL) or Active Ethernet, and is sometimes simply referred to as Ethernet power supply. It is a latest standard specification that uses the existing standard Ethernet transmission cable to transmit data and electric power simultaneously and maintains compatibility with the existing Ethernet system and users.

[0022] Such as Figure 1The utility model provides two independent lines, one of which is used for signal transmission. The optical line terminal 13 in the network cabinet 10 and the optical splitter 30 on different decks provide signal transmission function for the ONUs of the whole ship. The other line is used for power supply. The ONU centralized power supply box 20 in the network cabinet 10 and the ONU distribution box 70 on different decks provide power for the ONUs of the whole ship, and the ONU provides POE power supply function for use by various network terminal devices. Here, the optical line terminal 13 exchanges data with the server 11 through the core switch 12, and the optical splitter 30 and the ONU distribution box 70 are physical devices that do not need to be powered by a power supply. The ONUs here are the cabin ONU 40 and the public area ONU 50.

[0023] It can be seen that the utility model not only realizes the all-optical network transmission signal through the above design, but also realizes the POE power supply function that is free from the dependence on the POE switch. There is no need to connect any power supply in the middle, the wiring is simple, and less space is occupied on the ship, so that the ship can truly realize the all-optical network, thereby making the all-optical network truly play its own advantages.

[0024] The beneficial effect of the power supply method of the utility model is that the all-optical network does not need to be specially configured with a POE switch to meet the needs of individual devices that require POE power supply, thereby avoiding the increase in equipment, wiring types and complexity caused by the configuration of a POE switch. This power supply method does not require a relay power supply on a ship, just like optical cables, and uses the same distribution line as optical cables, thereby simplifying the wiring of the all-optical network.

[0025] The above are preferred embodiments of the present invention and the technical principles used therein. For those skilled in the art, without departing from the spirit and scope of the present invention, any obvious changes such as equivalent transformation, simple replacement, etc. based on the technical solution of the present invention are within the protection scope of the present invention.
