Description

  The present invention relates to an apparatus for calling another ship by wireless communication.

  Many ships are equipped with wireless communication devices for performing wireless communication with pilots of other ships. When another ship approaches the ship that it controls and there is a risk of collision, be careful of the ship operator who is at risk of collision by using a wireless communication device installed in the ship. (It is often the case that the operator of the ship and the operator of the wireless communication device mounted on the ship are different. Therefore, in this specification, only the person who operates the ship is referred to as the ship operator. Not only those who operate the wireless communication device mounted on the ship, but also the operator of the device mounted on the ship, not only the person who operates the device but also the ship on which the device is mounted. In addition, for the sake of simplicity, the expressions “call the ship's pilot” and “communication with the ship's pilot” are simply called “call the ship” and “communication with the ship”. What to express To.).

  When calling other ships with a wireless communication device, it is necessary to first recognize each other by calling each other's name. When the ship name of the other party is unknown, the other party is called by telling the traveling direction and characteristics of the ship. Then, the pilot of another ship is called himself by listening to the traveling direction, characteristics, etc. of the currently called ship with the wireless communication device and collating with the traveling direction, characteristics, etc. of the ship he is maneuvering. Recognize that

  In a radio communication device mounted on a ship, a call channel that is a frequency channel for calling another ship is assigned. The calling channel is defined as a channel that uses a frequency common to the world from the viewpoint of safe operation of the ship. In order to call the other party, the frequency channel of the wireless communication device is set as the calling channel, and after recognizing each other, the operation channel is switched to continue the wireless communication.

  As described above, when performing wireless communication by calling another ship using a wireless communication device, the ship name of the calling partner ship or the ship operated by the ship itself, the traveling direction, etc. are immediately grasped, and the wireless communication device The frequency channel needs to be set up quickly. However, it is difficult to perform this series of operations quickly, and a collision accident may occur if the operation of the ship operator is delayed even a little.

  Therefore, a ship calling radio device such as a DSC (Digital Selective Calling) device is widely used as a device for quickly performing a series of operations from setting a calling channel, calling the other party, and switching to an operation channel. An identification number is assigned to all ships on which the ship calling radio apparatus is mounted, and a series of operation processes are performed according to this identification number. When calling the other party's ship, the operator of the ship calling radio device inputs the identification number of the other party's ship and information on the operation channel used after the call.

  FIG. 7 shows a configuration of a ship calling radio device 5 that has been conventionally used. The ship calling radio device 5 includes a wireless communication unit 30 that performs wireless communication on a calling channel or an operation channel, a calling signal generation unit 14, and a hearing reception unit 22. The call signal generation unit 14 generates a call signal A including the identification number of the partner ship and information regarding the operation channel used after the call, and inputs the call signal A to the wireless communication unit 30. In addition, the information regarding the identification number of the partner ship and the operation channel is input by the operator via a keyboard or the like (not shown) provided in the ship calling radio apparatus 5. The radio communication unit 30 converts the incoming call signal A into a signal obtained by modulating the carrier wave, further converts the signal into a radio frequency, amplifies the signal, and transmits the signal via the antenna 16.

  A call channel is used to transmit the call signal A. The hearing reception unit 22 receives the call signal A transmitted from the ship calling radio device 5 mounted on another ship at any time via the antenna 20. Then, an identification number is extracted from the received call signal A, and it is monitored whether or not it is called by comparing it with its own identification number stored in the unique information storage unit 26.

  When the ship calling radio apparatus 5 recognizes that the ship on which the ship is mounted is called by the hearing reception unit 22, the display unit 28 displays that the ship is called from another ship. Then, the frequency channel of the wireless communication unit 30 is set as an operation channel under the control of the channel control unit 24, and is set in a state where wireless communication with the calling ship by the wireless communication unit 30 is possible. After such setting, the called ship's pilot can talk to the calling ship's pilot via the receiver 34.

  Thus, according to the ship calling radio device 5, by specifying the identification number of the ship of the other party to be called and the operation channel to be used after the call, a series from the setting of the calling channel to the setting of the operating channel. Can be automatically performed.

  In order to call the ship of the other party by the ship calling radio device 5, it is necessary to know the identification number of the ship of the other party in advance. It is conceivable to apply a ship identification system as means for knowing the ship identification number. In this system, a terminal device mounted on each ship notifies information about its own identification number and navigation information such as position and speed by wireless transmission, and the terminal device also provides information on identification numbers of other ships, Navigation information is received wirelessly, and a system such as AIS (Automatic Identification System) is realized. Hereinafter, the terminal device in this system is referred to as a ship identification device.

  FIG. 8 shows a configuration of a general ship identification device 7. The positioning unit 62 receives a positioning signal from a positioning satellite such as a GPS satellite via the antenna 60, calculates the position, speed, etc. of the ship on which it is mounted, and generates navigation information. Further, the ship information storage unit 66 stores unique information such as information related to the ship name, identification number, type of cargo, destination port, estimated arrival time, ship type, and the like. The own ship information generation unit 64 acquires the navigation information from the positioning unit 62 and the unique information from the ship information storage unit 66 to generate a ship information signal including the information, and via the radio circuit unit 68 and the antenna 70. Notification transmission is performed.

  The notification information acquisition unit 72 acquires a ship information signal that is transmitted by other plural vessels through the antenna 70 and the radio circuit unit 68. The display information generation unit 74 extracts navigation information of a plurality of other ships from the acquired ship information signal, and displays other ship graphic data for drawing the positions of the other ships on the graph, and unique information of other ships. The unique information array data for displaying various information in the array specified by the operator is generated. The display unit 76 displays a chart based on other ship graphic data and a chart based on the unique information array data in accordance with the switching of the operator.

  On the other hand, the other ship information output unit 78 outputs ship information signals from a plurality of other ships acquired via the antenna 70 and the radio circuit unit 68 in the order of acquisition. Hereinafter, a signal output in the order in which ship information signals from a plurality of other ships are acquired is particularly referred to as other ship information signal I. The other ship information signal I can be said to be a signal including other ship information in which navigation information and unique information of other ships are arranged as information elements.

  Since the ship identification device 7 can display information related to the identification numbers of other ships, navigation information, and the like, the operator can monitor the trends of ships that exist within a predetermined range from the ship on which the ship is mounted. Together with their identification numbers and the like.

  When a ship operator finds a ship that may collide with the ship identification device 7, the ship is called by the ship identification number displayed on the ship identification device 7, and the ship call radio device 5 wirelessly The collision may be avoided by performing wireless communication via the communication unit 30. However, the ship calling radio device 5 and the ship identification device 7 are configured separately and independently, and the ship identification number is input to the ship calling radio device 5 with reference to the display unit 76 of the ship identification device 7. On the other hand, since it is necessary to carry out by manual key input, it takes a long time to find a ship that may collide and call it.

  The ship calling radio device and the ship identification device are configured separately and independently because of the following background. (1) In the ship identification system, the system design is made on the assumption that the position and the course direction of other ships can be easily and accurately grasped, and the possibility of a collision or the like can be avoided in advance. . (2) Therefore, it is not assumed that radio communication is actively performed with other ships. (3) Under such a design philosophy, ship identification systems such as AIS have rapidly spread in recent years, and have been installed in many ships independently of radio devices.

  However, when operating a ship, it is most important from the viewpoint of safe ship operation to call other ships and actively communicate with the radio, and wireless operation by long-time operation of ship calling radio devices such as DSC devices. There are many requests from ship operators to take advantage of accumulated technology.

  In view of this, it is conceivable that information displayed on the ship identification device 7 is automatically acquired to avoid complicated operations such as manual key entry of the identification number. In this case, the design for further adding the ship calling radio apparatus 5 to the ship identification apparatus 7 that has already been designed is performed. When the ship calling radio device 5 is added to the ship identification device 7, it is necessary to construct an interface between both devices in the display information generation unit 74 of FIG.

  Further, as described above, ship identification systems such as AIS are widely used, and it is assumed that there is an increasing demand for further adding a ship calling radio apparatus to a ship identification apparatus already mounted on a ship. In this case, the ship identification device already mounted on the ship is modified, requiring a lot of labor and cost for the modification. Further, when the ship identification device already mounted on the ship is newly made into a combination of the ship identification device and the ship calling radio device, the existing value of the existing device can be attributed to nothing.

  Therefore, a configuration in which the other ship information signal I output by the other ship information output unit 78 in FIG. 8 is automatically acquired is conceivable. However, since the information included in this signal is only information obtained by arranging navigation information and unique information of other ships as information elements, a ship to be called is selected, and a call signal A including the identification number of the selected ship is quickly displayed. It is difficult to directly use as a signal for generating the signal.

  This invention is made | formed with respect to such a subject, and acquires the information regarding another several ship from the existing apparatus, and provides the ship call apparatus which calls another ship rapidly.

The present invention calls the other ship via wireless communication, performs wireless communication after the call using the different frequency channel than the frequency channel used for the call, a DSC radio apparatus for shipboard, other multiple other vessels information identification information and navigation information for each ship and the information element, obtained from AIS device mounted on the mounting ship, information elements of the other ship information with high order accessibility to mounting ship舶An information input unit that reads information according to an operation of the information input unit and an information input unit for performing a call operation are arranged by the sequence determination unit. An allocation unit to be allocated to each determined information element, and an information element allocated to the information element based on the array determined by the array determination unit. A display unit that displays the display of the means in association with each other, and when the information input unit is operated together with the display by the display unit, the identification information included in the information element to which the operated information input unit is assigned, An identification information acquisition unit acquired from an array determination unit, an identification information acquired by the identification information acquisition unit, and a call signal generation unit that generates a call signal including information on an operating frequency channel used after calling another ship, and the call A call signal transmission unit that transmits the call signal generated by the signal generation unit.

The ship-mounted DSC radio apparatus according to the present invention further includes an operation frequency channel acquisition unit that acquires information on the operation frequency channel from the information input unit, and the call signal generation unit includes the operation frequency channel acquisition unit. It is preferable to generate a paging signal including information on the operating frequency channel acquired by. The ship-mounted DSC radio apparatus according to the present invention further includes an operating frequency channel storage unit that stores information on the operating frequency channel, and the calling signal generation unit is stored in the operating frequency channel storage unit. It is preferable to generate a paging signal including information on the operating frequency channel.

Further, in the ship-borne DSC radio apparatus according to the present invention, wireless communication for performing wireless communication between the hearing reception unit that receives a signal for calling the mounted ship transmitted from another ship and the other ship of the calling source. And a communication channel control unit that controls a communication frequency channel of the wireless communication unit, wherein the communication channel control unit indicates a communication frequency channel of the wireless communication unit indicated by a signal received by the hearing reception unit It is preferable to set the operating frequency channel.

  Further, the ship-borne DSC radio apparatus according to the present invention includes a receiving unit that receives a radio signal transmitted from another ship, and a reception channel control unit that controls a reception frequency channel of the receiving unit, In the reception channel control unit, it is preferable that the call signal transmission unit transmits a call signal and sets the reception frequency channel of the reception unit to an operation frequency channel used after calling another ship.

  According to the present invention, since information elements of other ship information can be used after being arranged into information suitable for calling the other party, the ship to be called can be called quickly.

  FIG. 1 shows a configuration of a boat calling radio apparatus 1 according to the first embodiment of the present invention. The arrows in the figure indicate the flow of information, of which the flow of information related to control is indicated by broken lines. The control unit 40 controls the arrangement determination unit 10, the ship selection unit 12, and the call signal generation unit 14 by transmitting and receiving the control signal C. The operations of the other components will be described below together with the operation of the ship calling radio device 1.

  First, an operation for calling another ship will be described. The other vessel information signal I output from the vessel identification device 7 shown in FIG. This signal includes other ship information in which navigation information and unique information for each of the other ships are arranged as information elements, but the order of this arrangement has no particular meaning, and the ship identification device 7 obtains notification information. This is based on the order in which the ship information signals are acquired from the plurality of other ships in the unit 72.

  FIG. 2 shows a configuration of other ship information included in the signal input to the array determination unit 10. An identification number, a position represented by latitude and longitude, a direction in which the bow direction of the ship is 0 °, a distance from the ship, a ground speed, a course direction in which the north direction is 0 °, and a ship name are arranged. . In FIG. 2, a series of information written in one line from the identification number to the ship name is used as one information element. The other vessel information may include other unique information such as the type of cargo, the destination port, and the estimated arrival time.

Arrangement determining unit 10 stores other ship information for a predetermined number of ships (n ships), and stores the information elements of the other ship information for the stored n ships in the order of high possibility of access to the ship. Array. As the arrangement method, the following (1) to (4) are mainly considered.
(1) A current distance arrangement method in which information elements are arranged in order of increasing distance from the ship at the present time.
(2) A distance arrangement method after a designated time in which the distance from the own ship after the time t ₂ designated by the operator is calculated, and the information elements are arranged in order of increasing distance.
(3) An approach speed arrangement method that calculates an approach speed of the other ship to the own ship by calculating speed vectors of the own ship and the other ship at the present time, and arranges information elements in order of increasing approach speed.
(4) Calculate the straight track drawn by the ship and other ships until the time t ₄ specified by the operator, and information on the order of the ships having the straight track closest to the straight track of the ship A wake array method to arrange elements. Here, the distance between two tracks is defined as the distance between the points on each track at the time at which the two straight tracks are expected to be closest.

Any of the above arrangement methods (1) to (4) is considered to arrange the information elements in the order of high accessibility to the ship, and is selected by the operator according to the situation. Specifically, when the operator inputs a command from the key input unit 36, the control unit 40 sets the operation of the arrangement determining unit 10. In addition, the settings of the times t ₂ and t ₄ are stored in advance in the storage unit 38 by the operator via the key input unit 36 and the control unit 40, and the control unit 40 reads them to control the arrangement determining unit 10. To do. In the following description, a case where the current distance arrangement method is selected will be described.

  The arrangement determination unit 10 focuses information on the distance from the own ship among the information elements of the other ship information on the n ships, and arranges the information elements in order of increasing distance. Then, the other vessel information on which the arrangement is performed is input to the display unit 28 and the vessel selection unit 12, and the arrangement result is displayed on the display unit 28 as shown in FIG. From the arranged result, a key input waiting state for selecting a ship is entered. In the “call key” column of the display unit 28, key input numbers for selecting a vessel to be called out from the displayed vessels are displayed, and these are assigned by the arrangement determining unit 10 when arranging the vessels. It is done.

  When the operator determines from the display on the display unit 28 that the ship with the identification number “564647848” has a high risk of collision, the key “1” shown in the “calling key” field is input from the key input unit 36. Thus, the vessel selecting unit 12 selects an information element corresponding to the vessel having the identification number “5646447848” and inputs the information element to the calling signal generating unit 14. This operation is performed by the control unit 40 controlling the ship selecting unit 12 based on information input to the key input unit 36 by the operator.

  When the operator presses the key shown in the “calling key” column, the display unit 28 displays that the operation channel is waiting for input, and the ship calling radio apparatus 1 determines the operation channel. Information W can be input to the call signal generation unit 14 via the key input unit 36 and the control unit 40. Here, the operation channel refers to a frequency channel for continuing wireless communication after calling the other party and recognizing each other as described above. The information W for determining the operation channel is input to the call signal generation unit 14 by further inputting the operation channel after the operator presses the key indicated in the “call key” column. Note that the control unit 40 automatically reads out information for determining a radio channel previously assigned as an operation channel from the storage unit 38 and inputs the information to the call signal generation unit 14 without using a configuration in which the operation channel is key-input. A configuration is also possible.

  The call signal generation unit 14 generates the call signal A based on the input information element, the unique information of the own ship stored in advance in the unique information storage unit 26, and the information W for determining the operation channel. Here, the calling signal A is a signal for calling other ships by wireless communication, and is a signal including information on the identification number of the ship to be called and the own ship, and information on the operation channel used after calling. The call signal A can further include arbitrary unique information such as the ship to be called and the ship name of the ship.

  The call signal generation unit 14 extracts unique information such as the identification number of the ship to be called from the input information element, acquires the unique information such as the identification number of the own ship from the unique information storage unit 26, and determines the operation channel. When the information W to be designated is specified by the control unit 40, the call signal A is generated and input to the wireless communication unit 30. The radio communication unit 30 converts the input call signal A into a signal obtained by modulating the carrier wave, thereby converting the signal into a radio frequency band signal, amplifying the signal, and transmitting the signal via the antenna 16. Note that the call signal generation unit 14 inputs information about the call channel to the channel control unit 24, and the channel control unit 24 controls the wireless communication unit 30 so that the call signal A is transmitted through the call channel. The calling signal A transmitted as an electromagnetic wave from the antenna 16 is received by the ship calling radio apparatus 1 mounted on another plurality of ships.

  The call signal generation unit 14 inputs information included in the call signal A to the display unit 28, and when the call signal A is transmitted, the display as shown in FIG. The display contents are the calling channel, the identification number of the vessel to be called, and the operation channel, but it is also possible to display unique information other than the identification number of the vessel to be called.

  The call signal generation unit 14 further inputs information W for determining an operation channel to the channel control unit 24. Thus, after the call signal A is transmitted, the channel control unit 24 receives the wireless communication unit 30 at a predetermined timing so that communication for the pilot of the calling ship to respond is performed on the operation channel. The frequency can be controlled.

  The wireless communication unit 30 receives a signal based on the response of the boat operator who has called through the antenna 16, and notifies the operator of the boat calling wireless device 1 of the response through the speaker 32. Thereafter, communication by conversation between the operator of the ship calling radio apparatus 1 and the calling party is performed by the receiver 34. In this embodiment, the communication via the wireless communication unit 30 is assumed to be voice communication by the receiver 34 and the speaker 32, but general data communication such as facsimile data and image data can also be performed. It is.

  Next, the operation when the ship calling radio apparatus 1 receives a call will be described. The hearing reception unit 22 receives the call signal A transmitted from the ship calling radio apparatus 1 mounted on another ship at any time via the antenna 20, and extracts the identification number from the received call signal A. Specifically, the call signal A received by the antenna 20 is amplified, frequency-converted, and demodulated to extract an identification number. The hearing receiving unit 22 collates the extracted identification number with the identification number of the own ship stored in the unique information storage unit 26, and determines whether or not it is called.

  When the hearing receiving unit 22 recognizes that the ship carrying the ship is called, the information contained in the received call signal A is input to the display unit 28 and is called from another ship. Is displayed. FIG. 5 shows an example of the display. The display contents are the calling channel, the calling ship's identification number, the calling ship's ship name, and the operation channel, but it is also possible to display unique information other than the calling ship's identification number.

  The ship calling radio apparatus 1 displays on the display unit 28 that it has been called from another ship and is in a state in which wireless communication with the calling ship is possible. Specifically, based on the information W for determining the operation channel extracted from the received call signal A, operation processing such as setting the frequency channel of the wireless communication unit 30 to the operation channel is performed. Note that the setting of the frequency channel of the wireless communication unit 30 is performed under the control of the channel control unit 24. After such operation processing, the called ship's pilot can make a call for response to the calling ship's pilot via the receiver 34. Thereafter, communication by conversation between the operator of the calling ship and the operator of the ship calling radio apparatus 1 is performed by the receiver 34.

In the ship calling radio apparatus 1 according to the first embodiment shown in FIG. 1, the operator himself / herself has to determine the risk of collision of the ship according to the display shown in FIG . Their in this, the ship calls the wireless device 3 according to the second embodiment shown in FIG. 6, is provided with means for performing risk prediction automatically. The same components as those in the ship calling radio apparatus 1 in FIG.

  The other vessel information arranged by the arrangement determining unit 10 is input to the display unit 28 and the vessel selecting unit 12, and the arrangement result is displayed on the display unit 28 as shown in FIG. On the other hand, the other ship information signal I output from the ship identification device 7 shown in FIG. The risk prediction unit 50 stores other ship information on a predetermined number of ships (n ships), and sets the information elements of the other ship information on the stored n ships in order of high possibility of approaching the ship. Arrange. As the arrangement method, as described above, for example, (1) current distance arrangement method (2) distance arrangement method after specified time (3) approach speed arrangement method (4) wake arrangement method, etc. can be considered. Here, it is assumed that the risk prediction unit 50 performs the risk prediction using the arrangement methods (1) to (4) described above.

  In the risk prediction unit 50, the degree of accessibility, that is, the degree of risk is defined by numerical values from 1 to n. For example, the greater the numerical value, the greater the risk level. Then, information elements are arranged for each of the arrangement methods (1) to (4), and a risk level is assigned to the information element corresponding to each ship.

  The risk prediction unit 50 calculates a weighted average value for each information element based on the four risk levels assigned in each of the arrangement methods (1) to (4). The weighting of each arrangement method in the weighted average is stored in advance in the storage unit 38 via the key input unit 36 and the control unit 40, and is configured so that the control unit 40 can set it by reading it out. Is preferred. Next, the risk prediction unit 50 arranges information elements in descending order of the weighted average value based on the four risk levels. This arrangement is preferably displayed on the display unit 28.

  A risk determination is further performed on the information element having the largest four weighted average values. The risk determination is an information element that can determine the risk, for example, a ship corresponding to an identification number included in the information element when the distance from the own ship has a predetermined risk condition. Judge that there is a risk of collision. The predetermined risk condition is stored in advance in the storage unit 38 by the operator via the key input unit 36 and the control unit 40, for example, the distance from the ship is within 200 m, and the control unit It is preferable that 40 can be set by reading it.

  If it is determined by the risk determination that there is a collision risk, the risk prediction unit 50 determines that the warning unit 52, the display unit 28, and the ship selection unit 12 determine that there is a collision risk. Enter the corresponding information element. The warning unit 52 gives a warning that the ship corresponding to the identification number included in the input information element has a collision risk by a warning sound or voice guidance. In addition, the display unit 28 displays that the ship corresponding to the identification number included in the input information element may collide, and that the call signal A is automatically transmitted to the ship. Further, the ship selection unit 12 selects an information element corresponding to the ship having the identification number included in the input information element, and inputs the information element to the call signal generation unit 14.

  Note that the ship calling radio apparatus 3 is in a key input waiting state for selecting a ship from the arrangement result displayed on the display unit 28 until it is determined that there is a collision risk by the danger determination. Yes. In the key input waiting state, a key shown in the “call key” column is pressed, and the operation process in which the call signal A is transmitted by the input of the operation channel has priority over the risk prediction by the risk prediction unit 50. Further, even after it is determined that there is a collision risk by the risk determination, the risk prediction by the risk prediction unit 50 is interrupted together with the key press and the operation channel input shown in the “call key” column, It is also possible to employ an interrupt process in which a call signal A is transmitted by pressing a key indicated in the “call key” column and inputting an operation channel. If the arrangement result by the arrangement method from (1) to (4) above or the arrangement result by the weighted average value based on the four risk levels is displayed on the display unit 28, the operator can select any arrangement. Based on the results, the ship to be called can be selected.

  About the operation process in which the call signal generation unit 14 generates the call signal A based on the input information element, the own ship's unique information stored in the unique information storage unit 26 in advance, and the information on the operation channel and calls the other party Is the same as the ship calling radio apparatus 1 according to the first embodiment. However, when the call signal A based on the risk prediction is transmitted, the information W for determining a predetermined operation channel is automatically read from the storage unit 38 by the control unit 40 and sent to the call signal generation unit 14. Entered.

  In the ship calling radio device 3, since the ship having a collision risk is detected by the danger prediction unit 50 and the calling signal A for the ship is automatically transmitted, it is possible to prevent a collision accident due to human error. .
