Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

At present, the existing ship network communication mainly uses VSAT (Very Small Aperture Terminal) communication, which is greatly affected by rain and snow weather, and has the problems of narrow uplink and downlink bandwidths and high expenses.

Referring to fig. 1, a schematic view of a conventional ship satellite communication scenario is shown, in which a network signal in a conventional satellite transmission scheme is sent from a ship to a satellite, the satellite is sent to a ground station, and after the ground station responds, data is sent from the ground station to the satellite and then distributed to the ship requesting the data. In the process, only one communication channel is arranged between the ship and the ground, and if a large amount of data is required to be communicated in the process, a large amount of congestion is generated in a single channel. There is also a huge demand on satellite computing power when multiple vessels as shown in fig. 1 are requesting simultaneously. In order to cope with such a situation, the operator has to send more satellites to respond to the network request, which causes the cost of the network satellite broadband to further increase. However, in the future, ship intellectualization puts higher requirements on network delay, bandwidth and expense cost, and the current satellite broadband cannot meet the requirements.

Based on this, the embodiment of the utility model provides a pair of boats and ships communication system and novel boats and ships can provide 5G signal communication and satellite signal communication for boats and ships to realize the nimble switching of these two kinds of communication methods, do benefit to and reduce whole communication cost, and improve boats and ships travel and experience.

For the understanding of the present embodiment, a ship communication system disclosed in the embodiments of the present invention will be described in detail first.

The first embodiment is as follows:

the embodiment of the utility model provides a ship communication system, see fig. 2, for the schematic structure of this system, it is visible by fig. 2, this system includes 5G antenna array 11, VSAT communication satellite antenna 12, signal switching module 13, router 14, switch 15 and wireless hotspot 16. The 5G antenna array 11 and the VSAT communication satellite antenna 12 are respectively connected to a signal switching module 13, the router 14, and the switch 15 are sequentially connected, and the switch 15 is further connected to at least one wireless hotspot 16.

In one possible embodiment, the VSAT communication satellite antenna 12 in the marine communication system is located on the bridge deck of the vessel for better reception of satellite signals. Also, the 5G antenna array 11 in the system may be a 5G MIMO (Multiple-Input Multiple-Output) antenna array. The MIMO technology is to use a plurality of transmitting antennas and receiving antennas at a transmitting end and a receiving end, respectively, so that signals are transmitted and received through the plurality of antennas at the transmitting end and the receiving end, thereby improving communication quality. The multi-antenna multi-transmission multi-receiving system can fully utilize space resources, realize multi-transmission and multi-reception through a plurality of antennas, and improve the system channel capacity by times under the condition of not increasing frequency spectrum resources and antenna transmitting power. The MIMO technology can effectively utilize a plurality of spatial channels existing between a plurality of antennas between transmitting and receiving systems to transmit a plurality of mutually orthogonal data streams, thereby improving data throughput and communication stability without increasing communication bandwidth.

Further, the 5G antenna array 11 may also be a Massive MIMO antenna array, and the Massive MIMO technology further uses hundreds of antenna units to serve up to several tens of mobile terminals on the basis of the MIMO technology and limited time and frequency resources, thereby further improving data throughput and energy utilization efficiency. The antennas of a conventional TDD (Time Division duplex) network are basically 2 antennas, 4 antennas or 8 antennas, and the number of channels of the Massive MIMO is 64 or 128 or 256.

In the ship communication system, the 5G antenna array 11 and the VSAT communication satellite antenna 12 are used for transceiving a 5G communication signal and a satellite signal, respectively, so that ship-based 5G communication and satellite communication are realized. Here, when in the signal coverage of the shore-based 5G signal base station, the ship can implement signal connection with the shore-based signal base station through the 5G antenna array 11 and perform network communication. When the ship works in the ocean and cannot receive shore-based 5G signals, the VSAT communication satellite antenna 12 can be connected with a communication satellite, so that the network connection of the ship is realized.

The signal switching module 13 in the system is used for switching between two modes of 5G signal communication and satellite signal communication, and a user can freely select one communication mode for communication according to the signal condition of the area where the ship is actually located. When 5G signal communication is required, the signal switching module 13 is connected with the 5G antenna array 11, and a path is formed by the 5G antenna array 11, the router 14, the switch 15 and the wireless hot spot 16 which are connected in sequence, so that the network communication of the ship is realized. When satellite communication is needed, the signal switching module 13 is connected to the VSAT communication satellite antenna 12, and a path is formed by the VSAT communication satellite antenna 12, the router 14, the switch 15 and the wireless hotspot 16 which are connected in sequence, so that network communication of the ship is also realized.

Further, in the above-described communication system, the switch 15 is a network device for electrical (optical) signal forwarding, and it may be an ethernet switch. In one embodiment, a plurality of wireless hotspots 16 are connected to the system, and each wireless hotspot 16 is connected to the switch 15 via a data line, and each wireless hotspot 16 is distributed at each network access point on the vessel. Therefore, the wireless hotspots 16 are arranged at a plurality of positions of the ship, network service can be provided for all positions of the ship, and the network use is more convenient.

In order to increase the intelligence of the ship communication system and more conveniently switch between 5G signal communication and satellite communication, in one embodiment, referring to fig. 3, on the basis of fig. 2, the system further comprises a signal strength detection module 17 and a controller 18. The signal strength detecting module 17 is respectively connected to the 5G antenna array 11 and the controller 18, and the controller 18 is further connected to the signal switching module 13. In practical operation, the signal strength detection module 17 is configured to detect the signal strength of the 5G signal currently received by the 5G antenna array 11, in one of the manners, the signal strength may be detected periodically, and in a certain or several consecutive detection periods, when no 5G signal is detected, the signal strength detection module 17 sends a trigger signal to the controller 18 to automatically switch from the 5G communication mode to the satellite communication mode. Therefore, manual switching of personnel is not needed, uninterrupted communication network is facilitated, and ship travel experience is effectively improved.

In addition, in order to protect hardware devices of the communication system better, the signal strength detection module 17, the controller 18, the signal switching module 13, the router 14, and the switch 15 in the system may be provided in a control box together, and the control box may be provided inside the ship. Therefore, the hardware equipment is arranged in the control box, and the equipment is more conveniently and uniformly maintained.

In practical operation, in order to save limited deck space on a ship, the 5G antenna in the system may use a panel-type 5G antenna array 11, and compared with a traditional single-antenna configuration, the panel-type 5G antenna array 11 is formed by combining antenna array panels. When the 5G antenna array 11 is installed on a ship, the 5G antenna array 11 may be laid on the vertical wall of the ship body, or the 5G antenna array 11 may be arranged around a support rod. Referring to fig. 4, which is a schematic diagram of the installation positions of the 5G antenna array and the VSAT antenna, the installation manner of the 5G antenna array 11 shown in fig. 4 effectively reduces interference between antennas while saving the surface area of the compass deck.

The embodiment of the utility model provides a ship communication system, this ship communication system includes 5G antenna array, VSAT communication satellite antenna, signal switching module, router, switch and wireless hotspot; the 5G antenna array and the VSAT communication satellite antenna are respectively connected with the signal switching module; the signal switching module, the router and the switch are connected in sequence; the switch is connected to at least one wireless hotspot. The embodiment of the utility model provides a ship communication system, through set up 5G antenna array and VSAT communication satellite antenna on boats and ships, can provide 5G signal communication and satellite signal communication for boats and ships, through setting up signal switching module, can realize the nimble switching of these two kinds of communication modes, to coastal waters and ocean, can select the mode of communication according to the actual signal situation of boats and ships position, be favorable to reducing whole communication cost to improve boats and ships travel and experience.

Example two:

on the basis of the ship communication system provided by the first embodiment, the second embodiment of the present invention further provides a communication method between multiple ships.

Referring to fig. 5, a schematic diagram of a multi-vessel 5G network transmission scenario is shown, in the vessel communication scenario shown in fig. 5, there are a plurality of vessels, and each vessel is installed with the vessel communication system provided in the first embodiment and one of the possible embodiments. For each ship, it can independently select a 5G communication mode or a satellite communication mode, and here, the modes are described in a manner that each ship communicates with 5G signals.

Since each ship is provided with a 5G antenna array, and 5G is specific to D2D (Device to Device) technology, the single ship and shore-based connection is no longer only a single path. In the scenario shown in fig. 5, it is assumed that ships a, B are traveling along the shore and the base station signals are clear. If the ship C and the ship E are out of the shore-based antenna coverage range but within the signal coverage range of the 5G antenna array of the two ships, the ship C and the ship E can still communicate by using the 5G signal. For another example, if ship D is located farther than both ships C and E, but they are within the signal coverage of the 5G antenna arrays of both ships C and E, then ship D located farther away can also communicate using the 5G signal. By the same popularization, if the ship loader amount for communication by using the 5G antenna array is sufficient, it is not difficult to foresee that the ship communication quality is greatly improved on offshore coasts and inland waterway channels where ships are dense, and meanwhile, the network cost is reduced to the charge level of common civil mobile phones. On the other hand, with the addition of the characteristic of the 5G communication D2D, each ship is a base station, and when the number of the base stations is sufficient, the theoretically selectable communication channels are infinite, which correspondingly relieves the satellite of the heavy pressure of the data request in the ship-dense area.

In addition, referring to fig. 6, a schematic view of a combined application scenario of a multi-vessel 5G network and a satellite network is shown, in the vessel communication scenario shown in fig. 6, a vessel communication system provided in the first embodiment and one of the possible embodiments is installed on each of a plurality of vessels. In a communication network formed by a plurality of ships, a 5G network system can be matched with a satellite broadband for use, 5G signals can be used when the ship is near shore, and the ship can be switched into the satellite broadband signals when the ship is far away from sea and has no 5G signals. Compared with a single signal source using a 5G network or satellite broadband, the combined mode relieves the problem that the 5G signal is only covered offshore, and also relieves the problem that the broadband satellite is too expensive to be used offshore. In addition, local area networks can be formed among the fleet through the 5G network, and data can be transmitted efficiently. For this communication, when one of the vessels owns the network, the other vessels in the fleet can also obtain network connection through sharing.

The embodiment of the utility model provides a communication method between many boats and ships, based on the boats and ships communication system who provides of above-mentioned embodiment realizes, through the mode that adopts 5G signal communication and VSAT satellite communication combination, when combining the high-quality signal of coastal waters, has still taken into account the network experience among the ocean navigation process, is fit for unlimited navigation area boats and ships and uses. For offshore and inland ships, after the 5G marine system is popularized, a VSAT system is not used, and only 5G signals are used for communication, so that the ship space and the communication cost can be greatly saved.
