Then, the ship management method of the present invention using the system configured as described above will be described.

4 is a flowchart illustrating a pairing process between the fixed terminal 11 and the mobile terminal 12 according to an embodiment of the present invention.

As shown in FIG. 4, when the fixed terminal 11 is installed in a ship and power is applied, system initialization of the fixed terminal 11 is performed (S1), and the fixed terminal 11 is attached or driven by a user. By doing so, the mobile terminal 12 also performs system initialization (S2). Subsequently, a procedure for registering the mobile terminal 12 is performed.

If the fixed terminal 11 determines that there is no registered mobile terminal 12, the fixed terminal 11 encrypts its own fixed terminal ID (S3), and then transmits and receives a registration request message including the encrypted fixed terminal ID. The transmission is sent to the mobile terminal 12 existing within the radius (S4).

Accordingly, when the mobile terminal 12 receives the registration request message, the mobile terminal 12 decodes the registration request message to obtain a fixed terminal ID (a) (S5), and then the mobile terminal 12 moves its own. After encrypting the ID of the terminal 12 (S6), an authorization request message composed of the encrypted own mobile terminal 12 ID and the unencrypted fixed terminal ID is transmitted to the fixed terminal 11 (S7).

Thus, when the fixed terminal 11 receives the approval request message, the fixed terminal 11 decrypts the approval request message to obtain the mobile terminal 12 ID (S8), and then the fixed terminal 11 is fixed to its own After encrypting the terminal ID (S9), the authentication authentication message composed of its own encrypted fixed terminal ID and the non-encrypted mobile terminal 12 ID is transmitted to the mobile terminal 12 (S10).

Accordingly, when the mobile terminal 12 receives the approval authentication message, the mobile terminal 12 decrypts the approval authentication message to obtain the fixed terminal ID (b) (S11), and registers with the obtained fixed terminal ID (b). It is determined whether the fixed terminal ID (a) obtained from the request message matches (S12). When the fixed terminal IDs match, the mobile terminal 12 transmits an authentication confirmation message to the fixed terminal 11 (S13).

Thus, the pairing between the fixed terminal 11 and the mobile terminal 12 is made (S14).

On the other hand, in the communication between the fixed terminal 11 and the mobile terminal 12, all communication including the pairing is made by the encryption base. In addition, communication between the fixed terminal 11 and the base station 2, communication between the base station 2 and the center (3) is also made by the encryption base.

As one example, encryption-based communication between the fixed terminal 11 and the mobile terminal 12 may be made, which is a case of manufacturing a pair from the time of manufacture, in this case the fixed terminal 11 and The key may be stored in a combination of identifiers of the mobile terminal 12, and the key is used only when communication is made. This makes it impossible to pair with the other mobile terminal 12, the security of the communication between the fixed terminal 11 and the mobile terminal 12 can be maintained.

As another example, encryption-based communication may be performed between one fixed terminal 11 and a plurality of mobile terminals 12, which may be paired with each of the fixed terminals 11. In this case, in this case, secure communication between each of the mobile terminals 12 can be achieved by inputting different PINs to the fixed terminal 11 and each of the mobile terminals 12. It is possible to replace the mobile terminal 12, it is possible to achieve a pairing and secure communication by changing the PIN.

As another example, encryption-based communication may be performed only in a periodic information transmission / reception section by inputting a PIN to the fixed terminal 11 and the mobile terminal 12 prior to a transaction. By changing the secure communication between the fixed terminal 11 and the mobile terminal 12 can be achieved. Of course, after the transaction, the used PIN can be deleted, and if the same user is in communication, the PIN can be used without deleting the PIN. In addition, in this embodiment, only the communication between the fixed terminal 11 and the mobile terminal 12 has been described, but the same technique may be applied between the fixed terminal 11 and the base station 2. As such, it is preferable that the technology of changing the key every time communication is applied to ship information or flight information that is regularly transmitted and received.

5 is a flowchart illustrating a ship management method according to an embodiment of the present invention.

As shown in FIG. 5, when pairing is performed, the fixed terminal 11 transmits departure request information to the base station 2 (S21).

Accordingly, the base station 2 receives the departure request information, determines whether the departure is possible (S22), and if possible, transmits the departure approval information to the fixed terminal 11 (S23). Of course, if the ship is not able to sail, you will need to inform the ship why.

Subsequently, when the fixed terminal 11 transmits the received departure approval information to the mobile terminal 12 (S24), the mobile terminal 12 receives the departure approval information and displays it on the display unit 126 in the form of a message ( S25). The user of the navigation information transmission and reception terminal 1 confirms that the departure procedure is performed through the display unit 126.

The fixed terminal 11 generates ship information including position information, speed information, direction information and a fixed terminal ID transmitted from the GPS receiver 111 (S26), and generates the generated ship information to the base station 2 and the mobile terminal. Each transmission is made to (12) (S27, S28).

Accordingly, the base station 2 superimposes the ship information on the object detected by the radar and displays it on the electronic chart (S29), while the mobile terminal 12 displays the position, speed and direction of the ship on its own embedded electronic chart. (S30).

On the other hand, from the time when the ship information is generated, the base station 2 determines whether the ship departs from the departure / arrival boundary area set with the port as a reference point, and determines that the vessel departs from the departure / arrival boundary area, Departure is finally confirmed from pairing information of the fixed terminal 11 and the mobile terminal 12 (S31). That is, the departure approval information and the pairing information serve as a criterion for determining departure.

The base station 2 transmits the flight information including the weather information, the danger zone information, the emergency message, and the broadcast message to the fixed terminal 11 (S32). Accordingly, when the fixed terminal 11 transmits the received navigation information to the mobile terminal 12 (S33), the mobile terminal 12 receives the navigation information and outputs it to the display unit 126 (S34).

On the other hand, when the vessel enters the border area of the port for entry of the vessel, when the mobile terminal 12 transmits the entry request information to the fixed terminal 11 (S35), the fixed terminal 11 enters the port The request information is transmitted to the base station 2 (S36). In this embodiment, the port request is performed by the ship, but when the ship enters the border area of departure and arrival, if there is no special action in the base station (2) can proceed to the port approval process, the steps S35 and Step S36 may be omitted.

Accordingly, the base station 2 receives the entry request information and determines whether the entry is possible (S37), and if possible, transmits the entry approval information to the fixed terminal 11 (S38).

Subsequently, when the fixed terminal 11 transfers the entry approval information to the mobile terminal 12 (S39), the mobile terminal 12 receives the entry approval information and displays it on the display unit 126 in the form of a message (S40). The user of the navigation information transmission and reception terminal 1 confirms that a port entry procedure is performed through the display unit 126.

Thereafter, when the user of the navigation information transmission and reception terminal 1 detaches the mobile terminal 12 from the fixed terminal 11 or terminates the power supply of the mobile terminal 12, the fixed terminal 11 and the mobile terminal 12 are separated. Pairing is terminated (S41).

The fixed terminal 11 transmits pairing end information to the base station 2 (S42).

Accordingly, the base station 2 finally confirms the arrival from the arrival approval information and the pairing end information of the fixed terminal 11 and the mobile terminal 12 (S43). In other words, the entry approval information and the pairing end information serve as a criterion for determining entry.

In this way, the pairing information or the pairing end information between the fixed terminal 11 and the mobile terminal 12 can be used as reference information for determining departure and arrival. That is, the mobile terminal 12 serves as a key for receiving departure and arrival.

On the other hand, an emergency situation may occur when sailing a ship, and the shape of the emergency situation may be determined through pairing between the fixed terminal 11 and the mobile terminal 12.

-If there is no ship information detected on the radar, it can be determined that the device failure of the fixed terminal (11).

-If ship information exists without being detected on the radar, it can be determined as the stranding of the ship.

-If ship information does not exist without being detected on the radar, it may be judged as the ship sinking.

-After the paying end information is received, when the ship information is detected in the radar, it may be determined that the device failure or loss of the mobile terminal 12, or the abduction or escape of the user of the mobile terminal 12.

-If the ship information is detected on the radar after the paying end information is received, it may be determined that the device of the fixed terminal 11 is broken or lost, or that the user of the mobile terminal 12 is kidnapped or escaped. .

After the paying end information is received, if ship information exists without being detected in the radar, it may be determined that the mobile terminal 12 is abducted or escaped along with the stranding of the ship.

If the ship information is not detected in the radar after the paying end information is received, it may be determined that the mobile terminal 12 is abducted or escaped with the sinking of the ship.

In addition, among these emergency situations, the crew may drift at sea due to the escape of the user of the mobile terminal 12, in which case, the function of the long-range wireless communication unit (not shown) of the mobile terminal 12 is selected. By the direct communication with the base station (2) can transmit an accident occurrence signal, emergency rescue request signal.

Accordingly, the base station 2 may perform rescue operations by transmitting rescue information considering the current location of the ship or the final location where ship information does not exist to the navy or the maritime police.

Here, a method of managing a ship by matching radar and ship information will be described.

6 is a block diagram of a base station according to an embodiment of the present invention.

As illustrated in FIG. 6, the base station 2 includes a server 21 and a radar 22 including the ship information conversion unit 211. Of course, this configuration can also be provided in the center 3.

The vessel information converting unit 211 transforms and outputs the position information of the vessel information into an automatic identification system (AIS) format, which is a format recognized by the normal radar 22 and ECDIS (Electronic Chart Display and Information System).

By modifying and outputting the information displayed on the normal radar 22 and the ECDIS, the radar 22 and the object displayed on the ECDIS can be matched and managed.

Meanwhile, in the present embodiment, the case where the radar 22 is operated around the ECDIS has been described. However, the vessel may be displayed on the electronic chart through the normal display unit.

Here, the algorithm for transforming to the AIS form will be described.

Two considerations are required to convert AIS data. You need to change which message type to run and change to the AIS code character system.

First, the AIS message type used here uses message type 1, message type 2, message type 3, message type 4 and message type 5. Message type 1 to 3 displays the ship's location information, and message type 5 displays the length, width, and arrival port, which are the ship's specifications. Do it.

The character system of the received data follows the 8-bit system, and the AIS character system follows the 6-bit system and requires conversion. In addition, transmission message standard and data system are needed to recognize AIS. Message type 1 ~ 4 expressing basic information of ship and message type 5 expressing vessel type size are used.

으로 256개 문자세트(Set)가 존재하고, AIS 문자체계의 경우

으로 64개의 문자체계만 존재한다. 따라서 변경작업을 수행하기 위해서는 수신된 문자체계가 ASCII형태를 따르고 있기 때문에 수신된 데이터를 6비트 캐랙터로 변경해야 하는데 변경하는 방법은 아래와 같다.
First of all, in order to change the character system received in 8-bit into a 6-bit system recognized by AIS,

There are 256 character sets, and for AIS character system

There are only 64 character systems. Therefore, in order to perform the change operation, since the received character system follows the ASCII format, the received data must be changed to the 6-bit character.

Change of ASCII code value

6-bit code table Remove code values that are not recognized in the ASCII Value <48 or ASCII> 119 or (ASCII> 87 and ASCII <96) sections to remove unmatched code values to correspond to the corresponding code table. If the value is valid, ASCII> 128, ASCII + 32, and other values are calculated as ASCII + 40.
