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

The ship maneuvering support system according to the present invention exchanges information such as ship maneuvering support information and ship maneuvering command information by carrying a terminal device 1 with that of a ship operator and a supporter, and communicating with the plurality of terminal devices 1. Each terminal device 1 is configured to hold common information. Three examples are shown as forms of communication performed by the terminal device 1. That is, in the form of FIG. La, a host device 3 that collects ship maneuvering support information and ship maneuvering command information from each terminal device exists in a communication network 2 to which a plurality of terminal devices 1 are connected. It distributes ship maneuvering support information and ship maneuvering command information to each terminal device 1. In the form of FIG. Lb, each of the plurality of terminal devices 1 notifies the other terminal devices 1 of the marine vessel maneuvering support information or the marine vessel maneuvering instruction information of the own terminal device. Compared with the configuration in Fig. 1a, the communication network 2 in Fig. 1a is a star network centered on the host device 3, whereas the configuration in Fig. Terminal devices 1 communicate one-to-many or form a loop network. In the form of FIG. Lc, the terminal device 1 transmits information using AIS. Although details of AIS will be described later, in the form of FIG. 1 a or FIG. 1 b, the communication system of AIS used by AIS device 4 and the communication system of terminal device 1 are completely different systems. In the form of lc, the terminal device 1 transmits the ship maneuvering support information and the ship maneuvering command information by using the communication system of AIS by the communication device 4 ′ based on AIS. Hereinafter, details of the embodiment of FIG. 1A will be described.

As shown in FIG. 2, this ship maneuvering support system includes a plurality of terminal devices 1 carried by a ship operator and a supporter, a communication network 2 to which each terminal device 1 is connected, and a system for supporting ship maneuvering. A host device 3 for collecting from each terminal device 1 the ship maneuvering support information and the ship maneuvering command information determined by the ship operator.

The terminal device 1 has a screen section 11 for displaying a chart image, an input section 12 for inputting ship maneuvering support information and ship maneuvering command information, and a communication section 13 for providing an interface to a communication network. And a memory 14 for storing the distributed navigation support information, navigation instruction information, and chart image information. The screen unit 11 can restore the chart image information distributed from the host device 3 to a chart image and display the chart image, and can also convert the ship maneuvering support information and the ship maneuvering instruction information into an image and superimpose it on the chart image. When the chart image information is stored in the memory 14 of each terminal device 1 in advance, it is not necessary to distribute the chart image information from the host device 3 and the page to be displayed is not necessary. Information may be delivered.

The terminal device 1 is preferably composed of a portable personal computer. The portable personal computer is equipped with a liquid crystal display, a pointing device such as a stylus pen, a communication port, a storage device such as a semiconductor memory and a hard disk, and a LAN (wireless LAN) adapter. It can be assigned to section 12, communication section 13 and memory 14.

The terminal device 1 is carried by each staff member. Here, it is assumed that the master, pilot, navigator, and evening port crew carry the terminal device 1 respectively. The terminal device 1 owned by each staff is exactly the same for both hardware and software. However, the terminal device (terminal device for the ship operator) of the captain who is the ship operator , The right to input ship maneuvering command information is set. Generally, when the pilot is on board, the pilot is often the pilot and the captain is the supporter. In this case, the terminal 1 of the pilot is set as the terminal 1a for the pilot. The terminal device la for the ship operator to whom the input right for the ship operation command information is set can input both the ship operation support information and the ship operation command information. Other terminal devices 1b of pilots, navigators, and tug crews who are supporters can input only navigation support information. This is because if the vessel maneuvering command information could be input from another terminal device lb, the vessel maneuvering command information that the operator did not authorize would reach each staff member. The setting of the input right can be performed by, for example, registering the input right in the host device 3 in association with the ID number of the terminal device 1a or the address of the terminal device 1a in the communication network 2.

The communication network 2 may be a wired LAN only on the ship, but a wireless LAN may be used to communicate with a terminal device 1 used outside the ship, such as a tugboat, a berth, or a land-based control center. The host device 3 acts as a server in the wireless LAN. Each terminal device 1 transmits and receives radio waves to and from the access point. In addition, a mobile phone line can be used as the communication network 2 for operations within the mobile phone service area, such as when entering or leaving a port.

The host device 3 is composed of a computer and is provided onboard the ship. The host device 3 has a chart database 31 for storing chart data, a first memory 32 for storing ship maneuvering support information, a second memory 33 for storing ship maneuvering instruction information, and the like. The nautical chart database 31 stores topographical data of coastlines and contours, and data on the arrangement of signs such as buoys, targets, and lighthouses. The host device 3 reads the chart data of the sea area to be navigated retrieved from the chart database 31 based on the position of the ship, and processes the chart data into an information format that can be easily restored to a chart image and saves information capacity. It will be delivered to the terminal device 1. The first memory 32 stores the ship maneuvering support information provided from the various sensors and the ship maneuvering support information collected from the terminal device. The second memory 33 stores marine vessel maneuvering command information such as a scheduled course, a command course, and a command speed collected from the terminal device 1a for the marine operator.

In addition, the host device 3 includes various types of positioning systems, gyros, speedometers, radars, and the like. Sensor 34 is connected. The ship maneuvering support information provided from these sensors 34 to the host device 3 includes the own ship position, own ship course, own ship speed, other ship position, other ship course, other ship speed, destination, and the like. The host device 3 can calculate the relative position, such as the distance to the shore, the track of the own and other ships, and add the information to the ship maneuvering support by integrating the ship maneuvering support information and chart data provided from the sensor 34.

Although not shown in FIG. 2, the ship is equipped with an AIS device 4 as shown in FIG. The AIS device 4 is composed of a sensor input section connected to various types of ship measuring instruments such as a positioning device (for example, GPS) and a jay mouth, a unique information storage section that stores ship-specific information, and international conventions. It is composed of an AIS communication section that is subscribed to a specified automatic ship identification system (Automatic Identification at ion System; AIS, Unive rsa: 1—AIS). The current position of the ship is recognized by the positioning device, the heading is recognized by the gyro, the course to ground and the ground speed (synonymous with the ground speed) are calculated from the temporal change of the positioning result, and the own information of the ship is AIS information can be exchanged between ships equipped with AIS equipment 4 by calling the ship name, ship length, ship type, ship identification code, etc., and writing these AIS information in a message. . In AIS, each ship communicates by securing a slot or band using a multiplex communication system such as a time-division system. AIS communications occur regularly, for example, at least once every 12 seconds. The communication can be performed once a second for the night of own ship.

Since the AIS device 4 is connected to the host device 3, the host device 3 can take in AIS information from another ship. The host device 3 can distribute the obtained AIS information to the terminal device 1 as ship handling support information.

As shown in Figure 3, the ship is equipped with a VDR (Voyage Data Recorder) 5 that records the maneuvering status from the past to the present. VDR device 5 includes date, time, ship position, heading, bridge sound, communication sound, radar image, sound sounding, main alarm, rudder angle, engine telegraph, cargo door opening / closing, fireproof watertight door, hull load, wind direction, wind speed, etc. The main body of the device that captures the data from each sensor or device, and records these data for a predetermined time from the past to the present It consists of a capsule that stores the recording medium to be recorded in a watertight manner, so that the data at the time of the accident can be read from the capsule in the event of a marine accident. In the present invention, since the ship maneuvering support information and the ship maneuvering command information are collected in the host device 3, the VDR device 5 is connected to the host device 3, and the ship maneuvering support information and the ship maneuvering command information are provided as recording information on the capsule. Good.

Hereinafter, the operation of the ship maneuvering support system will be described.

Here, the case of port entry is taken as an example. Each terminal device 1 displays a chart image on the screen unit 11 based on the chart image information around the own ship distributed from the host device 3. That is, as shown in Fig. 4, shoreline (including jetty) 41, contour line (not shown), berth 42, target 43, lighthouse 44, buoy 45, etc. are displayed on the screen. . Further, each terminal device 1 creates an image of the own ship based on the own ship position and the own ship course, which are the ship maneuvering support information, and superimposes the image on the chart image. Own ship 46 is indicated by a symbol with its tip facing the own ship course on the own ship position on the chart image. An image of the track 47 is created from the track information. An image of another ship 48 is created from the position of the other ship and the course of the other ship. In addition, the vector is calculated from the course and speed of the other ship, and the image of the vector 49 is added to the image of the other ship. Further, an image of the route 50 is displayed based on the buoy 45 and the target 43.

The supporter sends to terminal device 1b the visual information obtained from the actual field of view, such as the approach of another ship, the appearance of a new ship, or the passage of a sign, and the information visually recognized from the radar scope of the sensor panel, the pointer of the measuring instrument, etc. It can be input as ship maneuvering support information. This ship maneuvering support information is collected by the host device 3 via the communication network 2.

The ship maneuvering support information collected by the host device 3 from the terminal devices 1 and the sensors 34 owned by each staff member and the ship maneuvering support information processed by the host device 3 are distributed from the host device 3 to all the terminal devices 1.

On the other hand, the master, who is the ship operator, inputs the ship operation command information such as the planned course, the command course, the command speed, etc. to the terminal device 1a. For example, a scheduled course can be entered by drawing on a chart image using a pointing device. The ship maneuvering command information determined by the terminal device 1a is collected by the host device 3 via the communication network 2, and the host device 3 Is transmitted to each terminal device 1.

Each terminal device 1 creates an image of the planned course based on the ship maneuvering instruction information and superimposes the image on the chart image. As a result, the scheduled course 51 determined by the master is displayed on all terminal devices 1. The command course and command speed (not shown) may be imaged and displayed on the chart image, or may be displayed as numerical values or scales outside the chart image or in a window.

In the present embodiment, the image relating to the maneuvering support information and the maneuvering instruction information is formed by each terminal device 1.However, this image is created by the host device 3 and is combined with the chart image and distributed. You may do so.

In this way, the entire vessel maneuvering support information and vessel maneuvering command information are displayed in common on all terminal devices 1. Since the ship maneuvering support information and the ship maneuvering command information are all displayed on the terminal device 1, the intention of the command can be well understood by the supporter.

Further, since the terminal device 1 is configured to be portable, the staff can move freely. For example, the master sometimes goes out to the wing (outside the bridge 61) and sees the actual field of view. At this time, he also carries the terminal device 1a, so he operates the boat in the same way as when he is in the cabin. It is possible to issue a command.

In addition, since a wireless LAN is used as the communication network 2, it is possible to distribute information completely common to the onboard staff to outboard staff, and to collect information on maneuvering support from the outboard staff. Can be. Therefore, it is possible to cooperate with more staff more closely.

In addition, ship maneuvering support information and ship maneuvering command information transmitted and received from each terminal device 1 at every moment are recorded in the VDR device 5. Therefore, in the event of a marine accident, the maneuvering support information and the maneuvering command information are read out from the capsule as data at the time of the accident, which can be useful for elucidating the cause of the accident.

When the ship 46, which was outside the buoy 45 at the time of entering the port, then passes through the buoy 45 on the side of the target 43, the host device 3 distributes the chart image information on a larger scale. . As shown in FIG. 5, each terminal device 1 displays a chart image in which the sea area including the own ship 46 and the berth 42 to which the ship 1 goes is zoomed in. PT / JP2003 / 003347

9 The planned course determined by the master is displayed as approach route 52. 53 is a symbol indicating the scheduled stop position.

When the ship 46 almost arrives at the scheduled stop position 53, the host device 3 distributes the chart image information of a further reduced scale. As shown in FIG. 6, each terminal device 1 displays a chart image in which the vicinity of the berth 42 is zoom-enlarged. Based on own ship position and own ship course, stopped own ship 46 is displayed. It can be seen that own ship 46 is in a posture almost parallel to berth 42. Own ship 46 will be almost translated and approach berth 42 by tugboat (not shown). The scheduled course determined by the master is displayed as an approach route 56 from the multiple points 54 on the side of the ship 46 to the multiple points 55 on the berth 42. The shore distances d 1 and d 2 from the ship 46 to the berth 42 on each approach route 56 and the approach speeds v l and v 2 are displayed numerically. Dougboat crew will proceed in accordance with this directive.

7a and 7b show examples of the processing procedure in the host device 3 and the terminal device 1, respectively.

As shown in FIG. 7A, the host device 3 collects ship maneuvering support information from the various sensors 34 and the terminal devices 1a and 1b, and calculates ship maneuvering support information that needs to be calculated. On the other hand, the host device 3 collects the ship maneuvering command information from the terminal device 1a and stores the ship maneuvering support information and the ship maneuvering command information in the first memory 32 and the second memory 33 (information). Update).

Although not shown, in the communication processing, the host device 3 and the terminal device 1 periodically communicate via the communication network 2, and each of the terminal devices 1 receives the ship maneuvering support information or the ship maneuvering instruction information individually input. The information is collected by the host device 3, and the integrated ship maneuvering support information and ship maneuvering command information are distributed from the host device 3 to each terminal device 1 together with the current location chart image information.

As shown in FIG. 7 b, the terminal device 1 inputs the maneuvering support information or the maneuvering command information from the input unit 12, stores it in the memory 14, receives it by the communication unit 13, and writes it in the memory 14. The screen section that converts the remembered navigation support information, navigation instruction information, and chart image information into images 1 Display in 1.

Next, details of the embodiment of FIG. 1B will be described.

As shown in FIG. 8, the program incorporated in the terminal device 1 includes a data storage unit 81 for storing and managing various data being processed, data for display from the data storage unit 81, and display on a screen. A display unit 82 that displays and stores data input on the screen in the data storage unit 81.Characters and character strings that correspond to elements such as push buttons displayed on the screen when pressed. Input / output unit for inputting / outputting and analyzing data with externally connected devices such as the AIS device 4 and the data storage unit 8 1 A communication unit 86 that performs various calculations on the same terminal device 1 that executes the communication protocol and communicates with the same terminal device 1 over the wireless LAN 2. Extract any part from image information and provide it to data storage unit 81 And the like chart information section 8 7 that. By reading these programs into a tablet-type personal computer, this evening-type personal computer can be operated as the terminal device 1 of the present invention.

This terminal device 1 is carried by the boat operator and each supporter in the same manner as in the embodiment of FIG. Since there is no host device, the communication method is different, but each terminal device 1 notifies the ship maneuvering support information or the ship maneuvering command information of its own terminal device 1 via the wireless LAN 2 so that all the terminal devices 1 have common information. Is the same. Therefore, the operation of the ship maneuvering support system is the same as the operation described in the embodiment of FIG.

The calculation unit 85 can execute a state check of the own ship and the other ship. That is, in the operator's terminal device 1, the operator operates the input unit 83 to input the planned course, while the AIS information of the own ship and other ships held by the AIS device 4 is stored in the IZ 0 unit. Since it can be referenced from 84, it is possible to check whether the ship is actually on the planned course. In addition, the possibility of collision with another ship can be checked from the planned course of the own ship and the AIS information of the other ship. The results of these status checks are displayed as navigational support information on the display unit 82, making it easier for the operator to operate the vessel.

In the form of m 1 c, the terminal device 1 uses the AIs communication system to And ship maneuvering command information. In other words, in AIS, each ship secures its own channel (slot or band) and uses it to exchange AIS information between each ship. Therefore, the terminal device 1 causes the communication unit 86 in FIG. 8 to execute the communication procedure specified in the AIS, and sets the communication unit 86 to a communication device 4 ′ conforming to the AIS.
