The ship automatic identification system (AIS) described above is a system for safely navigating a ship. By using an AIS device, in addition to the place where the ships are located at sea, the direction of travel and the speed, It has the feature that it can grasp information of other ships such as ship names that could not be obtained by marine data and ARPA (collision prevention assistance device).
However, AIS equipment is very expensive (for example, about 2-3 yen as a set), so it is installed in large vessels (convention vessels) that are obliged to install AIS equipment. It is not usually installed on small ships. Hereinafter, a ship equipped with an AIS device is called an “AIS-equipped ship”, and a ship not equipped with an AIS device is called an “AIS non-equipped ship”.

  The AIS described above is intended for safe navigation between AIS-equipped ships, that is, large ships, and is extremely effective for achieving this purpose, but nevertheless has the following problems.

(1) There is a limit to the number of ships that can be operated and monitored at one time with AIS equipment.
In the case of ship operation support, it is only necessary to know several ships around the ship, so AIS has a limit on the number of ships that can be supplemented within a certain time (for example, about 100 ships). Therefore, for example, in a congested sea area such as Tokyo Bay, when there are a large number of ships that require operation monitoring, there is a problem that it is not possible to monitor ships exceeding the limit number.

(2) Even with AIS-equipped ships, AIS equipment cannot monitor non-AIS-equipped ships. For this reason, only the AIS-equipped ship is displayed on the display device (CRT, etc.) of the AIS-equipped ship, and the non-AIS-equipped ship is not displayed even if it is close. Therefore, it is necessary to monitor a non-AIS-equipped ship that navigates nearby for safe operation by other means (radar or visual inspection), and cannot be monitored centrally with a large ship (AIS-equipped ship).

(3) Large ships (AIS ships) and small ships (non-AIS ships) must always be visually monitored for ships without AIS. For example, in a congested area such as Tokyo Bay, navigation safety Difficult to secure.

(4) Operation monitoring is not possible at remote locations.
AIS uses VHF near 162 MHz, and its transmission / reception distance is around 100 km. Therefore, for example, when a ship in Tokyo Bay is monitored (monitored), only a part of the bay can be monitored even at an AIS base station adjacent to the coast.
As a result, ships in Tokyo Bay and other areas could not be monitored in real time at locations remote from the coast (for example, the headquarters of the Japan Coast Guard).

Moreover, in the system of Patent Document 3, each ship is provided with a mobile communication device, a GPS receiver, and a VHF broadcast receiver, so that it is expensive like the AIS device, and the problems (1) to (4) are the same. Have.
In the system of Patent Document 4, since the positions of a plurality of ships are measured using GPS satellites and the positions of the respective ships are displayed, the installed equipment (GPS receiver, transmitter) can be made inexpensive, but the information obtained Is limited to location, etc., and is not available for operation monitoring. Moreover, it has the problem of said (1)-(4) similarly.

In the system of Patent Document 5, each ship-side terminal device using a common wireless channel used for voice communication converts the ship name, current position, speed, traveling direction, etc. of the ship into an analog signal and transmits it. The function to perform is required, and it is expensive like the AIS device, and has the same problems (1) to (4).
The system of Patent Document 6 uses a communication satellite and the Internet, but it is difficult to use for ship operation monitoring because it deals with troubles of the main engine and the like.
The device of Patent Document 7 is intended for safe operation and scheduled operation of own ship, does not have communication means with other ships, and cannot be used for ship operation monitoring.

  The present invention has been made to solve the various problems described above. That is, the object of the present invention is to (1) greatly increase the number of ships that can be operated and monitored at one time with AIS equipment, and (2) AIS-equipped ships and non-AIS-equipped ships, with inexpensive equipment and AIS-equipped ships. Ships that are not equipped with AIS can be monitored centrally and operational safety can be improved. (3) Remote and wide areas (eg, Tokyo Bay, Osaka) It is to provide a ship operation monitoring system capable of monitoring a ship in the entire bay in real time.

According to the present invention, specific AIS information, which is mounted on a plurality of AIS-equipped ships and includes position information, courses, ship speeds, ship names, and the like, is periodically broadcast in the VHF band, and other ships. A plurality of AIS devices that constantly receive and display AIS information broadcast from
Is mounted on a plurality of AIS not equipped vessels not equipped with the AIS equipment, GPS reception function, Internet connection function, and has an image display function, via the Internet, the sending AIS equipped vessels information of the AIS not equipped vessels A plurality of ship information communication means for receiving comprehensive information of the ship and the ship not equipped with AIS;
A plurality of ship information base stations having an Internet connection function, receiving ship information of the ship not equipped with AIS via the Internet, and transmitting the comprehensive information;
Having an Internet connection function, it receives AIS information from AIS equipped vessel in the VHF band, transmits the total information over the Internet, several AIS base for monitoring the movements of the ship over the reception distance VHF band Bureau,
There is provided a ship operation monitoring system comprising: a main server connected to the Internet and collecting and unifying ship information of the non-AIS ship and the AIS information as the comprehensive information in real time. .

  According to a preferred embodiment of the present invention, the ship information communication means has a function of displaying comprehensive information received via the Internet as an image.

  The communication medium used in the ship information communication means is a mobile phone having a mobile communication function, PHS, extra small radio, or wireless LAN.

  The main server detects a duplication and time difference between the ship information and the AIS information of the aggregated non-AIS-equipped ship, and centralizes and stores the time history data in a database.

  According to the configuration of the present invention described above, since a plurality of AIS base stations have an Internet connection function and can exchange information via the Internet, the AIS base station can be changed according to the degree of congestion of a ship in a designated sea area. It is possible to install a plurality of data related to the movement of the AIS-equipped ship without omission and to centralize the data collected at each base station. Therefore, even in a congested sea area such as Tokyo Bay, even when there are many ships that require operation monitoring, it is possible to monitor ships that exceed the limit number of each AIS device.

  In addition, AIS-equipped ships can receive comprehensive information on AIS-equipped ships and non-AIS-equipped ships via the Internet without installing ship information communication means. Both can be displayed, and small ships can be monitored centrally with large ships.

  In addition, even if a ship is not equipped with AIS, it is possible to receive general information about AIS-equipped ships and non-AIS-equipped ships via the Internet by installing ship information communication means. Both ships without AIS can be displayed, and small ships can be monitored centrally with large ships.

  Furthermore, since the ship information communication means, ship information base station, and AIS base station are connected via the Internet and have a main server, ships in Tokyo Bay and other areas can be moved away from the coast (for example, at sea). It can be monitored in real time at the Security Agency headquarters.

  Therefore, the ship operation monitoring system of the present invention can greatly increase the number of ships that can be operated and monitored at one time with AIS equipment, and (2) AIS with AIS-equipped ships and non-AIS-equipped ships with inexpensive equipment. It is possible to monitor onboard ships and non-AIS ships in an integrated manner and improve operational safety. (3) In remote locations from the coast (for example, Japan Coast Guard headquarters) It has excellent effects such as being able to monitor the ship in the whole bay) in real time.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In addition, in each figure, the same code | symbol is attached | subjected to a common part and the overlapping description is abbreviate | omitted.

FIG. 1 is a diagram schematically showing problems of a ship not equipped with AIS. In this figure, 1 is an AIS-equipped ship equipped with AIS equipment, and 2 is an AIS non-equipped ship not equipped with AIS. The left side of this figure shows the actual ship operating state, and the right side shows the ship operating state displayed on the display device of the AIS-equipped ship.
As shown in this figure, there has been a problem that the AIS non-equipped ship 2 cannot be monitored even if it is an AIS loaded ship 1 in the past.

FIG. 2 is an overall configuration diagram of the ship operation monitoring system of the present invention, and FIG. 3 is a schematic diagram thereof.
As shown in these drawings, the ship operation monitoring system of the present invention includes a plurality of ship information communication means 10, a ship information base station 12, and a plurality of AIS base stations 14, respectively.

The ship information communication means 10 has a GPS reception function, an Internet connection function, and an image display function. The ship information communication means 10 is mounted on a plurality of ships and transmits the ship information 5 of the non-AIS ship 1 via the Internet 7 and is mounted on the AIS. Receives general information 6 on ships and non-AIS ships.
The ship information communication means 10 has a function of displaying the comprehensive information 6 (ship information and AIS information) received from the main server 16 via the Internet 7 as an image. For this reason, the general information 6 transmitted and received via the Internet 7 is preferably text data in order to reduce the amount of data, but images may be directly transmitted and received. The ship information communication means 10 may be a mobile phone having a mobile communication function, PHS, extra-small radio, or wireless LAN.
Since these ship information communication means 10 are very inexpensive as compared with conventional AIS equipment (for example, around 100,000 yen), they should be installed in as many of the non-AIS-equipped ships 2 that do not carry the AIS equipment 3 as much as possible. preferable.

  The ship information base station 12 has an Internet connection function, receives ship information 5 of the ship not equipped with AIS 2, and transmits general information 6 (ship information and AIS information) received from the main server 16 via the Internet 7. To do. The ship information base station 12 is preferably a mobile communication base station.

  The AIS base station 14 has an Internet connection function, receives AIS information 4 from the AIS-equipped ship 1, and transmits general information 6 received from the main server 16 via the Internet 7.

The ship operation monitoring system of the present invention includes a main server 16 connected to the Internet 7 and aggregates ship information 5 of the non-AIS ship 2 and AIS information 4 of the AIS ship 1 in real time. Further, the main server 16 detects duplication and time difference between the ship information 5 and the AIS information 4 of the aggregated AIS non-loading ship 2 and unifies them as time history data and stores them in the database.
The main server 16 may be directly connected to one of the AIS base stations 14.

  FIG. 4 is an explanatory diagram for collecting AIS information by linking a plurality of base stations. As shown in this figure, according to the configuration of the present invention, since a plurality of AIS base stations 14 have an Internet connection function and can exchange information via the Internet 7, the degree of congestion of ships in a designated sea area can be increased. Accordingly, it is possible to install a plurality of AIS base stations 14, collect data related to the movement of the AIS-equipped ship 1 without omission, and unify the data collected at each base station 14. Therefore, even in a congested sea area such as Tokyo Bay, even when there are many ships that require operation monitoring, it is possible to monitor ships that exceed the limit number of each AIS device.

Hereinafter, a method for operating the system of the present invention will be described.
-AIS-equipped vessels When there are too many vessels, AIS equipment collects data with priority given to vessels close to AIS base stations (AIS-equipped vessels). For this reason, a plurality of AIS base stations 14 are installed in accordance with the degree of congestion of the ships in the designated sea area, data relating to the movement of the AIS-equipped ship 1 is collected without omission, and the data collected at each base station is unified. .
In order to realize the above, in the present invention, a main server 16 that centrally manages the AIS information 4 is provided, and a network 7 is constructed between each AIS base station 14 and data of each AIS base station 14 is stored. Aggregate to the main server 16 in real time.

-Network type marine vessel dynamics data collection system AIS information 4 is communicated directly over the Internet 7 as data communication to the main server 16. In particular, by monitoring data distribution in the terminal server of the AIS base station 14 and adding information other than the AIS information, information in excess of the information collected by the AIS base station 14 can be monitored in real time even in remote locations other than the main server 16. Is possible without using a dedicated line. Further, the information of the main server 16 can be monitored at a remote location via the Internet 7 as well.

-AIS ship without AIS By using a portable computer mounted on the ship without AIS 2, some communication means (cell phone, PHS, extra small radio, wireless LAN, etc.) and GPS as necessary, the main server 16 described above is used. A pseudo AIS function is realized by automatically transmitting / receiving navigation data to / from a WEB server connected to the LAN via the Internet. By using this method, it is possible to collect motion information at a relatively low cost even for a small vessel where the cost burden of AIS equipment is a problem.

-Utilization of collected data The AIS information 4 aggregated on the main server 16 is different in data duplication and collection time. These problems are processed and unified as time history data and registered in the database. In addition, in order to handle the database efficiently, it has a function to trace back and forth the movement of the designated ship.

According to the present invention described above, the following effects can be expected.
(1) It is possible to grasp the movement of the AIS-equipped ship in the designated sea area without omission.
(2) By accessing the main server and the database via the network, it is possible to effectively utilize the AIS information even in a ship (or place) where no AIS device is installed.
(3) Since the communication means is the Internet, it is possible to grasp information of a base station installed in a remote place in real time in real time.
(4) By introducing this system into an AIS-equipped ship, an AIS base station can be obtained. For this reason, organizations that have many ships, such as the Japan Coast Guard and others, can have base stations in various parts of the country, and can easily construct a monitoring system in the whole country (wide area).
(5) It is possible not only to grasp the movement of the ship without AIS but also to collect more detailed data.

  It should be noted that the present invention is not limited to the above-described embodiment, and can be variously modified without departing from the gist of the present invention.
