At the same time, unique information for each ship-holding group can be added, and ship operation management for each ship-owning group becomes possible.
In the unlikely event that an accident occurs, it is possible to grasp the wake on the management center side, and it is possible to identify the ship that caused the accident as a third party.
It is economical because the data transmission interval can be shortened only when an abnormality occurs.

  An embodiment of a ship operation management system according to the present invention will be described below with reference to the drawings. FIG. 1 is a system configuration diagram of the embodiment.

  First, this ship operation management system can grasp the positions of the ships 20 belonging to a plurality of groups, and grasp and manage necessary information for each group of ships belonging to each group. This system is composed of each ship 20, a management center 21, and each ship holding group 27.

  First, each ship 20 has one GPS positioning device 17 or two GPS positioning devices 17 or one GPS positioning device 17, a gyrocompass 18, a personal computer 19 and chart data (CD−) not shown. R) and ship side equipment for data communication terminals.

  Next, a computer system centered on the database server 22 is arranged in the management center 21, which includes a data server, a personal computer and chart data (CD-R), a distribution server 24 for the ship 20, and a (ferry operating company, A distribution server 25 for a ship holding group 27 (such as a cargo ship operating company, a working ship holding company, and a fishery cooperative association) is arranged, and the database server 22, each distribution server 24, 25, and the management personal computer 26 are in communication with each other. .

  Further, each ship possession group 27 is provided with a personal computer 28, chart data (CD-R) and network equipment.

  The personal computer 19 of each ship 20 and the distribution server 24 of the management center 21 are LAN-connected by packet communication similar to the conventional example of FIG. 2, and in this packet communication, data from each ship 20 is transmitted to the base station wirelessly. The data is sent to the computer system of the management center 21 via the communication line 32 and the router 33 on the management center 21 side via the router 30 on the base station 31 side. Sent by the reverse route.

  The personal computer 28 of each ship-owning group 27 and the distribution server 25 for the ship-owning group 27 are connected via the Internet. Instead of the Internet, LAN connection by the packet communication described above is also possible.

  Information on the position and direction of the ship 20 (when only one GPS positioning device 17 is arranged) is usually not obtained from the ship 20 by packet communication at intervals of 5 to 10 minutes. ) And the distribution server 24 for the ship 20 together with the time (information on navigation, berthing, cargo handling, standby, evacuation, occurrence of abnormality, etc.) determined by the ship-owning group 27 to which the ship 20 belongs. To send to. Note that the GPS time (international standard time) is used for the time, and the timing for transmitting information from each ship 20 to the management center 21 is more preferable for all the ships 20 at the same time. Large capacity equipment is required. Since the position of the ship 20 can be visually confirmed from a very long distance, there is no operational problem even if the ship 20 transmits at random, and the cost of the equipment is less if it is randomly transmitted.

  From the management center 21, the position and direction of the ship 20 (only one GPS positioning device 17 is arranged) from the ship distribution server 24 every predetermined time (5 to 10 minutes). And information on the position and direction of all the other ships 20 (when only one GPS positioning device 17 is arranged, direction information cannot be obtained) is transmitted to the personal computer 19 of the ship 20. These are displayed on the screen of the personal computer 19 arranged on the ship 20 together with a chart. Further, from the management center 21, it is also possible to transmit information on a marine area that cannot be navigated, such as a marine area under construction, weather information, and the like to the personal computer 19 of each ship 20 as necessary.

  From the ship-owning group 27, only the ship 20 belonging to the ship-owning group 27 can be received from the ship-owning group 27 distribution server 25 by authentication. In the ship-owning group 27, this information is displayed on the personal computer 28 and the positions and directions of all the ships 20 belonging to the ship-owning group 27 (when only one GPS positioning device 17 is arranged, the direction information is obtained. Can not manage). When information on the occurrence of an abnormality such as departure from the ship 20 or entry to a place where entry is prohibited is transmitted to the management center 21, the following measures can be taken. (Since packet communication is charged for the amount of data to be transmitted, the fee increases when the data transmission interval is shortened, so that the ship-owning group that bears the cost can be selected as appropriate.) It is also possible to set so as to transmit immediately to the management center 21 when an abnormality occurrence is input.

  The management center 21 automatically transmits an abnormal state message to the ship-owning group 27, and the data transmission interval from the ship 20 is automatically shortened (for example, every minute) by setting.

  It is automatically transmitted from the management center 21 to the ship-owning group 27 that it is in an abnormal state, and the data transmission interval from the ship-owning group 27 to the ship 20 can be shortened (for example, every 1 minute).

  The data server 24 of the management center 21 stores information on the time, position, and direction of all the vessels 20 (when only one GPS positioning device 17 is arranged, direction information cannot be obtained). When the ship 20 equipped with the system causes a collision accident, it is possible to display the track of all the ships 20 on the personal computer of the management center 21 from these information, and to investigate and prove which ship 20 has collided. be able to.

  An unmanned ship 20 such as a trolley is not equipped with a personal computer 19 but is provided with only a protocol converter and is equipped with a solar cell, thereby transmitting position, direction, and time data to the management center 21. It can be managed by the holding group 27. This makes it possible to grasp the drifting situation when the trolley drifts when the sea conditions are poor.
