E-navigation system providing for multi-communication and communication method

The present invention relates to an e-navigation system and a communication method that supports multiple communication, and more particularly, in the case where a ship and a ship, a ship and a land (control system) communicate with each other, when the size of data to be transmitted is large The present invention relates to an e-navigation system and a communication method supporting multiple communications for dividing the data into one or more and distributing the data to other communication means to reduce the transmission time of data.

According to the International Maritime Organization (IMO) 's International Convention for Safety of Life At Sea (SOLAS), which provides information on the security and safety of ships, automatic identification devices for various international navigation ships Automatic Identification System (AIS) and Ship Security Alert System (SSAS) should be installed. In addition, discussions on Long-Range Identification and Tracking of ships (LRIT), including the Maritime Life Safety Convention, or international agreements such as the Asian Piracy Prevention Convention and the International Maritime Security Regulations, are national obligations for the Contracting States.

In Korea, the ship safety law stipulates that the ship's location call device should be installed on passenger ships and international ships of 300ton or more to secure safe operation of the ship through real-time monitoring of the ship's operation status and to respond quickly in case of an accident. In addition, a national crisis management system is in place for joint utilization of marine disaster information among major agencies such as the National Security Council (NSC), National Intelligence Service, Ministry of Public Administration and Security, and the Korea Maritime Police Agency.

 However, the conventional communication system between ship and ship, and ship and land (control system) is based on the type of ship and the range of navigation, for example, by the automatic identification system (AIS) in coastal areas, and by satellite communication in the ocean area, navigational information is exchanged. In particular, since most fishing boats use the voice communication system managed by the fishing service station, there is a small number of collisions between small fishing boats and large ships near the coastal waters because information communication between ships using different communication systems is not performed properly. It is happening.

On the other hand, in Korea, the Ministry of Land, Transport and Maritime Affairs manages AIS communication network and the Maritime Police Agency manages VHF / DSC communication network. It is an obstacle to the establishment of a comprehensive marine management system for marine resource development.

In addition, even when the size of the data to be transmitted and received is large, since data is transmitted through one communication means, there is a problem in that data is transmitted slowly.

Therefore, e-navigation has been attracting attention for providing various ship operation information and navigation environment information, and for efficient use of ship's stable operation, life-saving rescue activities, marine safety, marine environment protection activities, and correction of marine resources.

It is achieved by an e-navigation system supporting multiple communications, characterized in that for transmitting the partial data to a communication server or another vessel at the same time.

In addition, another object of the present invention is a first step of measuring the current position of the ship, and setting the list information of the communication means corresponding to the position; A second step of setting an optimum communication means by reflecting any one or more of QoS information, cost information, and status information among the list information of the communication means; Setting at least one communication means other than the optimum communication means as candidate communication means, and determining whether communication is possible among the candidate communication means; A fourth step of generating partial data obtained by dividing the state data including the navigation information measured by the ship into one or more when communication is possible through one or more communication means including the optimum communication means; And a fifth step of transmitting the partial data to a communication server or another ship by using the one or more communication means.

In addition, the partial data of the present invention preferably includes identification information for identifying the order of the state data.

In addition, even after setting the optimum communication means of the present invention, if the position of the ship is predicted to be unable to communicate with the optimum communication means, it is preferable to automatically convert the optimum communication means.

Therefore, when the e-navigation system and communication method supporting multiple communication of the present invention can be connected to one or more communication means, it is possible to divide and transmit data divided by one or more communication means, thereby transmitting and receiving data. It is effective to shorten.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an e-navigation system supporting multiple communication according to an embodiment of the present invention. Referring to Figure 1, it shows a ship-shore communication.

The ship's switching server 100 transmits the state data including the navigation information measured by the ship to the land, and when the state data is transmitted to the land, the ship's switching server 100 receives the terminal data from the land communication server 100.

One or more communication means are connected to the switching server 100 in the ship. The communication means is selected corresponding to the position of the vessel, and the switching server 100 automatically selects the optimum communication means. In order to communicate with other ships as well as on land, select the best means of communication.

The switching server 100 may transmit the state data using an optimal communication means when transmitting the state data, but when the state data is large or the speed of the communication means is slow, the switching server 100 generates one or more pieces of partial data divided by relative data. To transmit the partial data to the communication server 200 using one or more communication means.

If the priority is distress or emergency, the cost is not considered, and if it is safe or general, the cost is searched for.

Since the ship may be in motion, the connected means of communication may be lost. Therefore, the switching server 100 reflects the position of the ship in real time and automatically converts the communication means when it is predicted that the connected communication means is likely to be cut off. Prediction of the disconnection of the communication means predicts that the communication signal is weak or using the communication range in the communication means.

The communication server 200 has the partial data transmitted from the switching server 100 each having an identification number, so that the communication server 200 combines the partial data transmitted from one or more communication means and recovers the state data to the terminal 300. To be provided).

The communication server 200 may receive the state data from the switching server 100, but transmits the operation data transmitted from another ship to the switching server 100. At this time, the communication server 200 also divides the navigation data into one or more pieces of data to transmit to the switching server 100 using one or more communication means.

When one or more communication means are available, the data processing unit 110 divides the state data into partial data, collects one or more pieces of data transmitted from the communication server, and generates flight data.

The partial data is data obtained by dividing the state data by one or more, and the partial data includes identification information for identifying the data.

The communication switching unit 120 sets an optimal communication means among one or more communication means, and sets other communication means as candidate communication means. In establishing the optimum means of communication, the ship's position is taken into account, and the ship's position includes CDMA, Wibro, VHF, HF, AIS, satellite networks, etc. It is preferable to include Wibro, WLAN, VHF, satellite network and the like.

In addition, QoS information, data status information, cost information, etc. are considered. The QoS information includes the speed, data size, seamless, etc. of the communication means, and the cost information is the communication cost incurred when transmitting and receiving data corresponding to the communication means. The status information of the data indicates the priority of the data, and the priority of the data may be set according to the ship's situation, and the priority may be divided into status information such as distress, emergency, safety, and general. If the priority is distress or emergency, the cost is not considered, and if it is safe or general, the cost is searched for.

In determining the communication means according to the position of the ship, the communication switching unit 120 automatically converts the communication means in anticipation that the connected communication means may be disconnected because the ship may move in a fluid manner. Prediction of the disconnection of the communication means predicts that the communication signal is weak or using the communication range in the communication means.

The multi-communication interface unit 130 is an interface for compatibility for communication using a communication means such as CDMA, Wibro, VHF, HF, AIS, satellite network. That is, when using communication with the outside, since one or more communication means is comprised, the interface of each communication means is included.

The database 140 stores state data including navigation information of the vessel measured from the sensor unit and the position detection unit, and stores the navigation data transmitted from the communication server. In addition, the system systematically manages data such as storing, deleting, and modifying data and information generated in the vessel or outside.

The controller 150 controls the data processor 110, the communication switching unit 120, the multi-communication interface unit 130, and the database 140. In addition, when there is at least one communication means among the communication means set from the communication switching unit 120, the partial data generated by the data processing unit 110 is transmitted to the communication server using at least one communication means. That is, it is determined whether multiple communication is possible by one or more communication means, and when possible, the state data is transmitted to the communication server using several communication means at the same time.

3 is a flowchart illustrating a communication method of e-navigation supporting multiple communication according to an embodiment of the present invention. Referring to FIG. 3, the position of the vessel is measured (S310), and list information of communication means corresponding to the position of the vessel is provided (S320).

The status information of the data indicates the priority of the data, and the priority of the data may be set according to the ship's situation, and the priority may be divided into status information such as distress, emergency, safety, and general. If the priority is distress or emergency, the cost is not considered, and if it is safe or general, the cost is searched for.

The candidate communication means is set except for the optimum communication means among the list information of the communication means. In addition to the optimal communication means, it is determined whether communication is possible among the candidate communication means (S340), and when communication is possible, the state data including the navigation information measured by the ship is divided into partial data (S350). The partial data is data obtained by dividing the state data by one or more, and the partial data includes identification information for identifying the data.
