Description

Vessel Operation Support System

Technical Field

The present invention relates to a ship driving support system for supplying support information from a support agent or sensor to a ship driver. More specifically, the present invention relates to a ship driving support system for improving information sharing among ship staff.

Background

The operation of the vessel is based on the cooperation of the staff involved in the operation of the vessel, where the staff are the ship's driver (one for each task, such as a pilot, captain, chief navigator, etc.) and support personnel (navigator, tugboat). Crew, etc.). In particular, in the case of large ships, the cooperation of staff is essential, and it is important to keep in close contact between the staff and to provide them with common information. This is most important when assistance is required to operate the vessel, for example when the vessel enters or departs.

Vessel driving support devices have been developed to achieve this purpose. However, these devices are developed under the assumption that they will be controlled by one ship driver, and there is a problem that ship driving assistance information provided from the staff on the ship is concentrated on the ship driver.

As shown in FIG. 9, a ship pilot 62, a captain 63, a navigator 64, and a steersman 65 for steering a rudder or propulsion handle on a steering console are provided by a bridge; 61) in a space. Before the above-mentioned conventional ship driving support devices were developed, the ship pilot 52 or the navigator 64, which was a support agent, provided oral support information to the master 63, who was a ship driver, and the captain 63 was a helming officer ( 65) verbally commanded. Therefore, the support information provided by the support personnel is also transmitted to the helmsman 65, who could easily understand the meaning of the command that the captain 63 said. However, the above-mentioned conventional ship driving assistance apparatuses display assistance information on a display (not shown) positioned in front of the captain 63. Therefore, although the captain 63 can easily obtain the assistance information, the assistance information displayed on the screen of the display is not visible to the helmsman 65. This makes the helmsman 65 uncomfortable, because when he receives a command from the ship driver, there is insufficient information to understand the meaning of the command.

Furthermore, in the situation shown in FIG. 10, the tugboat 73 helps the large ship 71 to dock at the pier. At this time, the communication between the ship pilot 62 and the tugboat crew 72 or the auxiliary personnel 75 of the pier 74 is made of a radio, this cooperation is not as strong as the cooperation on the ship. The tugboat crew 72 and assistant 75 on the outside of the ship are also important staff. Therefore, it is desirable that support information or instructions be communicated to them.

It is an object of the present invention to provide a ship driving support system for improving information sharing among staff in order to overcome the problems of the prior art described above.

Summary of the Invention

The present invention provides a plurality of terminal devices in which vessel operation support information for supporting vessel operation and vessel operation command information determined by the vessel driver are executed by the vessel driver and support personnel. It is exchanged by performing communication between them, thereby providing a ship driving support system in which a terminal device holds common information.

A host device for collecting ship driving support information and ship driving command information from the terminal device may be provided in a communication network connecting the terminal device, and the ship driving support information and ship driving command information are distributed to the terminal device by the host device. Can be.

The terminal device may transmit its ship driving assistance information and ship driving command information to another terminal device.

Detailed Description of the Invention

Preferred embodiments according to the present invention will be described below in detail with the accompanying drawings.

The ship driving support system according to the present invention is configured such that a ship driver and a support agent execute each terminal device 1, and information such as ship driving support information or ship driving command information may be transmitted through a plurality of terminal devices ( Exchanged by 1), and each terminal device 1 has common information. Three specific examples of communication operated by the terminal device 1 will be described below. In the embodiment shown in FIG. 1A, the host device 3 which collects ship driving assistance information and ship driving command information from the terminal device may be provided on a communication network 2 to which a plurality of terminal devices 1 are connected. The ship driving assistance information and the ship driving command information may be distributed from the host device 3 to the terminal device 1. In the embodiment shown in FIG. 1B, each of the plurality of terminal devices 1 may transmit its ship driving assistance information or ship driving command information to another terminal device. Comparing the embodiment of FIG. 1B with the embodiment of FIG. 1A, the communication network 2 shown in FIG. 1A is a star-like network concentrated on the host device 3, while FIG. In the illustrated embodiment, no host device is installed and the terminal device 1 communicates in a one-to-many mode, which is called a loop-like network. In the embodiment shown in FIG. 1C, the terminal device 1 transmits information by using AIS. The AIS will be described in detail below. In the embodiment shown in FIG. 1A or FIG. 1B, the AIS communication system using the AIS device 4 and the communication system of the terminal device 1 are certainly independent systems, whereas the terminal device 1 shown in FIG. ) Transmits the ship driving assistance information and the ship driving command information by using the AIS communication system via the communication device 4 'constituting the AIS.

The embodiment shown in FIG. 1A is described in detail below.

As shown in FIG. 2, the ship driving support system according to the present invention includes a plurality of terminal devices 1 executed by the ship driver and the support personnel, a communication network 2 connected to the terminal devices 1, and ship driving. It consists of a host device (3) for collecting the ship driving information and the ship driving command information determined by the ship driver to support the terminal device (1).

The terminal device 1 stores a screen 11 for displaying a chart image, an input unit 12 for inputting ship driving assistance information or ship driving command information, a communication unit 13 which is an interface of a communication network, and an input. And a memory 14 for storing ship driving assistance information, ship driving instruction information, and chart image information. The screen 11 may restore and display the chart image information distributed from the host device 3, and may add the ship operation assistance information and the ship operation command information converted into the image to the chart image. Furthermore, when the chart image information is further stored as a database in each memory 14 of the terminal device 1, it is not necessary to distribute the chart image information from the host device 3, and the displayed page information is distributed. Can be.

The terminal device 1 may be configured as a portable personal computer (PC). Portable PCs include liquid crystal displays, pointing devices such as stylus pens, semiconductor devices, memory devices such as hard disks, and LAN adapters (wireless LANs). These components may be assigned to screen 11, input 12, communication 13 and memory 14.

The staff runs their personal terminal device 1. That is, it is assumed that the captain, the ship pilot, the navigator and the tugboat crew carry out their personal terminal device 1. It is assumed that all staff's terminal devices have exactly the same hardware and software. However, the authority to input the ship driving command information is set in the terminal device 1a (the ship driver terminal device) of the captain who is the ship driver. In most cases, when a ship pilot touches a ship, the ship pilot becomes a ship driver and the captain becomes a support agent. At this time, the terminal device 1 of the ship pilot is set to the ship terminal device 1a. The vessel driver terminal device 1a having the authority to input ship driving command information may input both ship driving assistance information and ship driving command information. Terminal devices 1b, executed by assistant personnel, pilots, navigators, and tugboat crews, can only enter vessel driving assistance information. This is because if the ship driving command information is input from the terminal device 1b, ship driving command information not authorized by the ship driver will not be transmitted to the staff. For example, setting the input authority is made by recording the input authority in the host apparatus 3 according to the ID number of the terminal device 1a or the address of the terminal device 1a of the communication network 2.

When used only inside a ship, the communication network 2 may be a wired LAN. However, a wireless LAN may be preferably used for communication to terminal devices 1 used outside the ship, for example in tugboats, berths, land control stations and the like. The host device 3 serves as a server in a wireless LAN. The terminal device 1 transmits and receives electromagnetic waves between access points. Further, when entering or departing, the cellular phone circuit can also be used as the communication network 2 in the service area of the cellular phone.

The host device 3 is composed of a computer and provided inside the ship. The host device 3 includes a chart drawing database 31 for storing chart data, a first memory 32 for storing ship driving assistance information, a second memory 33 for storing ship driving command information, and the like. The same can be configured. The chart database 31 stores terrain data such as coastlines and contours and data related to the location of navigational aids such as buoys, landmarks, lighthouses, and the like. The host device 3 reads the chart data from the chart database 31 for the expected navigation area associated with the ship's position, and obtains an information scheme that enables easy restoring of the chart image and saving information throughput. Process the data and distribute the data to the terminal device 1. The first memory 32 stores ship driving assistance information supplied from various sensors and ship driving assistance information collected from a terminal device. The second memory 33 stores ship operation command information such as a predetermined route, command bearing, command speed, and the like collected from the ship driver terminal device 1a.

Various sensors 34, such as navigation systems, gyro, speedometers, radars and the like, are connected to the host device 3. The ship driving assistance information supplied from the sensor 34 to the host device 3 includes its own position, route and speed, and the position, route and speed of another vessel, destination, and the like. By combining the ship driving assistance information supplied from the sensor 34 with the chart data in the host device 3, it is possible to calculate relative positions such as the distance to the coast and the distance between the ship and other ships, and the calculated relative positions. Can be added to the ship driving assistance information.

As shown in FIG. 1A, the AIS device 4 is generally installed in a ship (this device is not shown in FIG. 2). The AIS device 4 is a sensor input connected to various navigational measurement devices such as navigation devices (e.g. GPS, etc.), a rotary compass, a unique information storage for vessel-specific information, and an automatic identification system embodied by international treaties. It consists of AIS communication unit connected to (AIS or Universal AIS). It is a navigational device that constantly knows the ship's current position, a rotating compass that recognizes the bow's orientation, land-based course and land-based speed (equivalent to land-based speed) in time. The AIS apparatus 4 is equipped with the AIS device 4, which can be calculated from the change of the navigation results according to it, and by importing the ship's own name, length, form, ID code, etc. from the unique information section, and also recording such AIS information in a communication message. AIS information can be exchanged between ships. AIS performs communications by ensuring slots or bands for all of the vessels by using multiple communication systems such as time division systems. For example, AIS communication is performed at least once every 12 seconds. In the ship's own data, communication is performed once a second.

By connecting the AIS device 4 to the host device 3, it is possible for the host device 3 to obtain AIS information from another ship. The host device 3 can distribute the AIS information obtained as ship driving assistance information to the terminal device 1.

As shown in FIG. 3, the Voyage Data Recorder (VDR) device 5 is installed inside the ship to record the ship operation situation from the past to the present. The VDR device 5 includes the main body, date, time, ship position, bow bearing, bridge sound, communication sound, radar image, acoustic depth sounding, chief alarm sound, key angle received from each sensor or instrument. various data related to rudder angle, engine telegraph, ship's cargo door condition, fire and watertight doors, ship body load, wind direction, wind speed, etc., and a recording medium for recording such data for a specified time from past to present It consists of a capsule contained in the waterproof case. During a marine disaster, data relating to the time of the accident is read from the capsule. Ship driving support information and ship driving command information according to the present invention are collected from the host device (3). Therefore, the VDR device 5 can be connected to the host device 3, and the ship driving support information and the ship driving command information can be provided in a capsule and recorded.

The operation of the ship driving assistance system is described below.

For example, the case where a ship enters is demonstrated. The terminal device 1 displays the chart image on the screen 11 based on the chart image information around the vessel distributed from the host device 3. Thus, as shown in FIG. 4, the coastline 41, the contours (not shown), the marina 42, the landmarks 43, the lighthouse 44, the buoy 45, etc., including the breakwater, are shown on the screen. It is. Further, the terminal device 1 plots an image of the vessel on the basis of the position and the route of the vessel, that is, the ship driving assistance information, and adds the image on the chart image. The vessel 46 is marked by the symbol of the vessel position on the chart surface, the pointed portion of the vessel symbol is the direction along the ship's course. The image of the vessel route 47 is plotted from the vessel route information. The image of the other vessel 48 plots its position and orientation. Furthermore, the vector is calculated from the route and speed of the other ship, with the vector 49 image added to the image of that other ship. An image of the route line 51 is displayed based on the buoy 45 and the landmark 43.

The support personnel input visual information such as the approach of other ships observed on the actual site, the appearance of new ships and the navigational aids, or the information observed from the radar and the indicator of the sensor panel to the terminal device 1b as ship driving assistance information. can do. This ship driving assistance information is collected by the host device via the communication network 2.

The ship driving assistance information collected by the host device 3 from the terminal device 1 of the sensor 34 or all the staff and the ship driving assistance information processed by the host device 3 are all terminals from the host device 3. To the device 1.

Meanwhile, the captain who is a ship driver inputs ship driving command information such as a predetermined route, a command route, a command speed, and the like into the terminal device 1a. For example, a predetermined route may be entered as a drawing with a pointing device on the chart image. Ship operation command information determined by the terminal device 1a is collected by the terminal device 3 via the communication network 2, and the host device 3 distributes the ship driving command information to the terminal device 1.

The terminal device 1 plots a predetermined route image based on the vessel operation command information, and adds the image on the chart image. As a result, the predetermined route 51 determined by the captain is displayed on all terminal devices 1. Command routes or command speeds (all not shown) may also be converted to images and displayed on the chart, and the images may be displayed outside the chart image or in a window with numbers or scales.

In the embodiment according to the present invention, the image related to the ship driving assistance information or the ship driving command information is formed in the terminal device 1, but the images are also formed in the host device 3, and can be synthesized with the chart image. Can be further distributed.

Therefore, all ship driving assistance information and ship driving command information are generally displayed on all terminal devices 1. Since the ship driving assistance information and the ship driving instruction information are displayed without omission on the terminal device 1, the intention of the command can be easily understood by the support personnel.

Since the terminal device 1 is configured to be portable, the movement of the staffs cannot be restricted. For example, sometimes the captain is on the wing outside of the bridge 61 to see the actual site, but since the captain can run terminal device 1a, the ship operation command is carried out as if the captain was inside the bridge. Can be.

Furthermore, since the wireless LAN is used as the communication network 2, the same information as distributed inside the ship can be distributed to the staff outside the ship, and the ship driving assistance information can be collected from the staff outside the ship. . Therefore, many staffs can certainly cooperate closely.

Ship driving support information and ship driving command information transmitted and received by the terminal device 1 are recorded in the VDR device 5 at every instant. Thus, in case of a disaster, the ship driving assistance information and the ship driving command information can be read from the capsule as data related to the accident time, which helps to clarify what happened.

If the vessel 46, which was outside the vicinity of the buoy 45 at the time of entry, passes through the buoy 45 on the side of the landmark 43, the host apparatus 3 distributes the garbage information even if it is enlarged. . As shown in FIG. 5, the terminal device 1 displays a sea chart image of the sea area including the ship 46 and the marina 42, which indicates the destination direction and is in an enlarged state. The predetermined route determined by the captain is indicated as the approach path 52. The vessel symbol 53 indicates a predetermined position when the vessel stops.

When the vessel 46 reaches the planned position 53 at which the vessel will stop, the host device 3 distributes the chart image information in an enlarged size. As shown in FIG. 6, the terminal device 1 displays an island chart image in which the vicinity of the marina 42 is enlarged. The stationary vessel 46 is displayed based on its position and orientation. The vessel 46 is moved substantially parallel by a tugboat (not shown), moving close to the marina 42. The predetermined route determined by the captain is indicated as a proximity path 56 from a plurality of points 54 on the board of the ship 46 to a plurality of points 55 on the berth 42. The distances d1, d2 from the ship 46 to the berth 42 and the proximity speeds v1, v2 in the proximity path 56 are represented by numbers. The tugboat crew acts on orders.

7 shows an example of a flowchart processed by the host device 3 and the terminal device 1.

As shown in FIGS. 7A and 7B, the host device 3 collects ship driving assistance information from the sensor 34 and the terminal devices 1a and 1b, and calculates necessary ship driving assistance information. As another route of the flowchart, the host device 3 collects ship operation command information from the terminal device 1a. The ship driving assistance information and the ship driving command information are stored in the first memory 32 and the second memory 33 (update of information).

In the course of communication, the host device 3 and the terminal device 1 communicate periodically via the communication network 2. The vessel driving assistance information or vessel driving instruction information input from the individual terminal device 1 is collected by the host apparatus 3, and the combined vessel driving assistance information and the vessel driving instruction information are combined with the chart image information related to the current position. Together from the host device 3 to the terminal device 1.

As shown in FIG. 7B, the terminal device 1 inputs ship driving support information or ship driving command information from the input unit 12, and stores them in the memory 14. Ship driving support information, ship driving command information, and chart image information received by the communication unit 13 and stored in the memory 14 are converted into images and displayed on the screen 11.

The embodiment shown in FIG. 1B is described in detail below.

As shown in FIG. 8, a program operating in the terminal device 1 includes a data storage unit 81 for storing and managing data during procedure execution; A display unit 82 for retrieving the displayed data from the data storage unit 81, displaying the data on the screen, and storing the data input on the screen in the data storage unit 81 again; An input unit 83 for inputting characters, character strings, and commands to the display unit 82 when an element such as a push button displayed on the screen is pressed; An input / output unit 84 for performing data analysis and data input-output to an externally connected device such as an AIS device 4; A calculation unit 85 for performing calculation on the data in the data storage unit 81; A communication unit 86 for implementing a communication program and performing communication from the wireless LAN 2 to a similar terminal device 1; And a chart chart information unit 87 for extracting an arbitrary portion from chart chart image information related to a geographically wide area and supplying it to the data storage unit 81.

This terminal device 1 is implemented by the ship driver and the support personnel as in the embodiment shown in FIG. The communication system is different because there is no host device. However, since the terminal device 1 transmits the ship driving support information or the ship driving command information of its own terminal device 1 via each wireless LAN 2, all the terminal devices 1 share the common information. Keeping is similar. Thus, the operation of the ship driving assistance system is the same as the operation described with respect to the embodiment shown in FIG.

Therefore, in the terminal device 1 of the ship driver, the ship driver operates the input unit 83 and inputs a predetermined route. On the other hand, the AIS information of its own vessel and other vessels held by the AIS apparatus 4 may be displayed via the input / output unit 84. Therefore, it is possible to check whether his ship is actually going the scheduled route. In addition, the possibility of collision with other ships can be checked based on the AIS information related to the ship's predetermined route and other ships. The result of the status check is displayed by the display unit 82 as ship driving assistance information, whereby the ship driver can easily operate the ship.

In the embodiment shown in 1c, the terminal device 1 transmits ship driving assistance information and ship driving command information using the AIS communication system. Therefore, in AIS, each channel (slot or band) is guaranteed for each ship and can be used to exchange AIS information between ships. Here, the terminal device 1 executes the communication procedure specified by the AIS in the communication unit 86 shown in FIG. 8, and sets the communication unit 86 as the communication device 4 'conforming to the AIS.
