　 ところで、無線通信機同士は、同じ周波数帯域（ＭＦ、ＨＦ、ＶＨＦ等）でのみ通信可能であり、どの周波数帯域に対応しているかは無線通信機によって異な る。そのため、従来は、ある周波数帯域で他船に対して通信開始処理を行い、応答があって初めてこの他船と通信可能であることを把握できる。なお、他船の無 線通信機がその周波数帯域に対応していない場合は応答がない。また、その周波数帯域で通話中である場合は、通話に割り込む形となってしまう。そのため、別 の周波数帯域で再び通信開始処理を行う必要がある。このように、他船と通信可能であるか把握するまでに時間が掛かってしまう。 By the way, wireless communication devices can communicate with each other only in the same frequency band (MF, HF, VHF, etc.), and which frequency band is supported depends on the wireless communication device. Therefore, conventionally, it is possible to grasp that it is possible to communicate with another ship only when there is a response by performing a communication start process for the other ship in a certain frequency band. In addition, there is no response when the other-line wireless communication device does not support the frequency band. Further, when a call is in progress in that frequency band, the call is interrupted. Therefore, it is necessary to perform communication start processing again in a separate frequency band. In this way, it takes time to determine whether communication with other ships is possible.
　特許文献１から４では、他船から様々な情報を取得する技術が開示されているが、上記の課題を解決するために必要な情報は取得されていない。なお、移動体同士（又は移動体と基地局）で通信を行うシステムであれば、船舶に限られず同じ課題が存在する。 Patent Documents 1 to 4 disclose techniques for acquiring various information from other ships, but information necessary for solving the above problems is not acquired. In addition, if it is a system which communicates between mobile bodies (or a mobile body and a base station), it will not be restricted to a ship, but the same subject exists.
　本発明は以上の事情に鑑みてされたものであり、その主要な目的は、他の移動体が備える無線通信機と通信できるか否かを短時間で把握するための無線通信用表示装置を提供することにある。 The present invention has been made in view of the above circumstances, and a main object of the present invention is to provide a wireless communication display device for grasping in a short time whether or not communication with a wireless communication device included in another mobile body is possible. It is to provide.

Therefore, for example, by determining the communication channel so that the external wireless communication device is separated from the communication channel in use, interference and noise can be avoided.

It is preferable to determine a frequency band and a communication channel for this purpose.
　これにより、ユーザ側ではなくシステム側で周波数帯域及び通信チャンネルを決定するため、ユーザ側で周波数帯域及び通信チャンネルを選択する手間を省くことができる。 Thereby, since the frequency band and communication channel are determined not on the user side but on the system side, it is possible to save time and effort for selecting the frequency band and communication channel on the user side.
　 前記の無線通信用表示装置においては、前記制御部は、前記表示部に表示された前記移動体が選択された場合に、選択された前記移動体と通信を行うための周波 数帯域及び通信チャンネルを求めて前記表示部に表示し、選択された周波数帯域及び通信チャンネルで無線通信の開始を指示することが好ましい。 In the wireless communication display device, the control unit, when the moving body displayed on the display unit is selected, a frequency band and a communication channel for communicating with the selected moving body.

　次に、図面を参照して本発明の実施形態を説明する。初めに、図１及び図２を参照して、相互通信システムの概要及び各船舶が備える無線通信システムについて説明する。 Next, an embodiment of the present invention will be described with reference to the drawings. First, with reference to FIG.1 and FIG.2, the outline | summary of a mutual communication system and the radio | wireless communications system with which each ship is provided are demonstrated.
　 相互通信システム１は、船舶同士又は船舶と陸上局（基地局）が互いに無線通信するためのシステムである。図１に示すように、船舶及び陸上局には、無線通信 機１１が設けられている。無線通信機１１は、ＤＳＣ（Ｄｉｇｉｔａｌ　Ｓｅｌｅｃｔｉｖｅ　Ｃａｌｌｉｎｇ）通信等を行って他の船舶又は陸上局と無線通信 を行うための装置である。なお、本明細書では、「通信」又は「無線通信」は、データのやり取りだけでなく音声通話も含む概念とする。 The mutual communication system 1 is a system for wireless communication between ships or between a ship and a land station (base station). As shown in FIG. 1, a ship and a land station are provided with a wireless communication anchor 11. The wireless communication device 11 is a device for performing a wireless communication rod with other ships or land stations by performing DSC (Digital Selective Calling) communication or the like. In this specification, “communication” or “wireless communication” is a concept including not only data exchange but also voice communication.
　 各船舶には、図２に示す無線通信システム５が設けられている。無線通信システム５は、第１無線通信機１１ａと、第２無線通信機１１ｂと、ＧＰＳ受信機１５ と、ＡＩＳ送受信機１７と、表示装置（無線通信用表示装置）２０と、を備えている。なお、基本的には各船舶が備える無線通信システム５の構成は略同じであ るが、無線通信機１１の機種及び台数は通常は異なっていると考えられる。 Each ship is provided with a wireless communication system 5 shown in FIG. The wireless communication system 5 includes a first wireless communication device 11 a, a second wireless communication device 11 b, a GPS receiver 15, an AIS transceiver 17, and a display device (display device for wireless communication) 20. . In addition, although the structure of the radio | wireless communications system 5 with which each ship is equipped is fundamentally the same, it is thought that the model and the number of radio | wireless communication apparatuses 11 are usually different.
　第１無線通信機１１ａは、第１無線アンテナ １２ａと接続されている。また、第１無線通信機１１ａは、ＤＳＣ（Ｄｉｇｉｔａｌ　Ｓｅｌｅｃｔｉｖｅ　Ｃａｌｌｉｎｇ）通信を行う。これにより、他の船 舶又は陸上局が備える無線通信機とデータ通信を行ったり、マイク機能及びスピーカ機能を有する通話装置１１０（図１を参照）を用いて音声通話を行ったりす ることができる。 The first wireless communication device 11a is connected to the first wireless antenna 12a. The first wireless communication device 11a performs DSC (Digital Selective Calling) communication. Thereby, data communication can be performed with a radio communication device included in another ship or land station, or a voice call can be performed using the call device 110 (see FIG. 1) having a microphone function and a speaker function. it can.
　本実施形態のように海上において無線通信機同士で無線通信を行う場合は、通信相手を特定するための識別情報としてＭＭＳＩ番号が用いられる。なお、ＭＭＳＩ番号は船舶又は陸上局毎に設定された文字列であり、異なる船舶又は陸上局には異なるＭＭＳＩ番号が設定されている。 When performing wireless communication between wireless communication devices at sea as in the present embodiment, an MMSI number is used as identification information for specifying a communication partner. The MMSI number is a character string set for each ship or land station, and different MMSI numbers are set for different ships or land stations.
　 また、無線通信機同士で無線通信を行うためには、同じ周波数帯域かつ（予め定められた）同じ通信チャンネルの電波を使用する必要がある。この周波数帯域と しては、例えばＭＦ（中波）、ＨＦ（短波）、及びＶＨＦ（超短波）等を挙げることができる。どの周波数帯域を使用できるかは無線通信機の機種によって異な る。本実施形態の第１無線通信機１１ａは、ＭＦ及びＨＦを使用して無線通信を行うことができる。 In addition, in order to perform wireless communication between wireless communication devices, it is necessary to use radio waves of the same frequency band and (predetermined) communication channel. Examples of this frequency band include MF (medium wave), HF (short wave), and VHF (very short wave). Which frequency band can be used depends on the type of wireless communication device. The first wireless communication device 11a of the present embodiment can perform wireless communication using MF and HF.
　通信チャンネルとは、上記の周波数帯域のうち通信中に使用する周波数である。なお、周囲で使用されている通信チャンネルと周波数が近い通信チャンネルで無線通信を行った場合、無線通信に混信及びノイズが発生することがある。 The communication channel is a frequency used during communication in the above frequency band. When wireless communication is performed on a communication channel having a frequency close to that of a communication channel used in the surroundings, interference and noise may occur in the wireless communication.
　 第２無線通信機１１ｂは、第２無線アンテナ１２ｂと接続されている。第２無線通信機１１ｂは、第１無線通信機１１ａと同様に、他の船舶又は陸上局が備える 無線通信機と無線通信を行うことができる。第２無線通信機１１ｂは、ＶＨＦを使用して無線通信を行うことができる。従って、図２に示す無線通信システム５ では、ＭＦ，ＨＦ，ＶＨＦに対応している。以下の説明では、第１無線通信機１１ａと第２無線通信機１１ｂとをまとめて無線通信機１１と称することがある。 なお、無線通信機１１の機種及び台数は船舶又は陸上局毎に異なるため、対応可能な周波数帯域も船舶又は陸上局毎に異なる。 The second wireless communication device 11b is connected to the second wireless antenna 12b. Similarly to the first wireless communication device 11a, the second wireless communication device 11b can perform wireless communication with a dredging wireless communication device provided in another ship or a land station. The second wireless communication device 11b can perform wireless communication using VHF. Accordingly, the wireless communication system 5 shown in FIG. 2 supports MF, HF, and VHF. In the following description, the first wireless communication device 11a and the second wireless communication device 11b may be collectively referred to as the wireless communication device 11. Note that since the model and the number of the wireless communication devices 11 are different for each ship or land station, the frequency bands that can be supported are also different for each ship or land station.
　 ＧＰＳ受信機１５は、ＧＰＳアンテナ１６と接続されている。ＧＰＳ受信機１５は、ＧＰＳ衛星からの測位信号を、ＧＰＳアンテナ１６を介して受信する。 ＧＰＳ受信機１５は、この測位信号に基づいて自船の位置（詳細には、ＧＰＳアンテナ１６の位置、地球基準の絶対位置）を求めて表示装置２０の制御装置２１ へ出力する。なお、ＧＰＳ受信機１５は、ＧＰＳ以外のＧＮＳＳを用いて自船の位置を求めても良い。 The GPS receiver 15 is connected to the GPS antenna 16. The GPS receiver 15 receives a positioning signal from a GPS satellite via the GPS antenna 16. The GPS receiver 15 obtains the position of the ship (specifically, the position of the GPS antenna 16 and the absolute position of the earth reference) based on the positioning signal and outputs it to the control device 21 of the display device 20. Note that the GPS receiver 15 may determine the position of the ship using a GNSS other than GPS.
　ＡＩＳ送受信機１７ は、ＡＩＳアンテナ１８と接続されている。ＡＩＳとは、自船の位置情報や航行情報等を周囲に送信するシステムである。ＡＩＳ送受信機１７は、他船から送信 されてくるＡＩＳ信号をＡＩＳアンテナ１８を介して受信したり、自船の情報をＡＩＳ信号としてＡＩＳアンテナ１８を介して送信したりする。ＡＩＳ信号は、 無線通信機１１を用いた無線通信と異なり、相手を特定せずに信号を送信する。即ち、ネットワーク通信で例えれば、無線通信機１１はユニキャスト又はマルチ キャストに類似した送信を行い、ＡＩＳ送受信機１７はブロードキャストに類似した送信を行う。なお、本明細書では、ネットワーク通信以外であっても、相手 を特定せずに（即ち不特定多数に）情報を送信することを「ブロードキャスト」と称する。従って、ＡＩＳ送受信機１７はブロードキャストによりＡＩＳ信号を 送信する。 The AIS transceiver 17 is connected to the AIS antenna 18. AIS is a system that transmits the position information, navigation information, etc. of the ship to the surroundings. The AIS transmitter / receiver 17 receives an AIS signal transmitted from another ship via the AIS antenna 18 or transmits information on the ship as an AIS signal via the AIS antenna 18. Unlike the wireless communication using the wireless communication device 11, the AIS signal transmits the signal without specifying the other party. That is, in the case of network communication, the wireless communication device 11 performs transmission similar to unicast or multi-cast, and the AIS transceiver 17 performs transmission similar to broadcast. In the present specification, even if it is other than network communication, transmitting information without specifying the other party (that is, to an unspecified number) is referred to as “broadcast”. Therefore, the AIS transceiver 17 transmits the AIS signal by broadcasting.
　ここで、一般的にＡＩＳ信号として送信される情報は、船舶の名称、位置、船首方位、船速、目的地、積載物、ＭＭＳＩ番号等である。ＡＩＳ送受信機１７は、他船が送信したＡＩＳ信号を受信して解析することで、他船の情報を求めて制御装置２１へ出力する。 Here, information generally transmitted as an AIS signal is the name, position, heading, ship speed, destination, load, MMSI number, etc. of the ship. The AIS transceiver 17 receives and analyzes the AIS signal transmitted from the other ship, obtains information on the other ship, and outputs it to the control device 21.
　 本実施形態のＡＩＳ送受信機１７は、上記の情報に加え、自船（無線通信システム５）が備える無線通信機１１に関する情報、詳細には無線通信機１１の通信機 能及び通信状態を示す情報（通信機情報）を送信することができる。なお、他の船舶にも無線通信システム５が設けられているため、ＡＩＳ送受信機１７は、他 船のＡＩＳ送受信機１７が送信した他船の通信機情報を受信する。 In addition to the above information, the AIS transmitter / receiver 17 of the present embodiment includes information related to the wireless communication device 11 included in the ship (wireless communication system 5), specifically, information indicating the communication function and communication state of the wireless communication device 11. (Communication device information) can be transmitted. In addition, since the wireless communication system 5 is provided also in the other ship, the AIS transceiver 17 receives the communication information of the other ship transmitted by the AIS transceiver 17 of the other dredger.
　本実施形態では、通信機情報として、無線通信システム５ が備える無線通信機１１が対応している周波数帯域、当該周波数帯域毎を使用して通信中か否か、及び通信している場合に使用している通信チャンネルが含まれ る。ＡＩＳ送受信機１７は、他船から受信した通信機情報を解析して制御装置２１へ出力する。なお、ＡＩＳ信号の解析は、ＡＩＳ送受信機１７で行っても良い し、制御装置２１で行っても良い。 In the present embodiment, as the communication device information, the frequency band supported by the wireless communication device 11 included in the wireless communication system 5 否, whether or not communication is being performed using each frequency band, and used when communicating The communication channel that is being used is included. The AIS transceiver 17 analyzes the communication device information received from the other ship and outputs it to the control device 21. The analysis of the AIS signal may be performed by the AIS transceiver 17 or the control device 21.
　表示装置２０は、制御装置２１と、表示部２２と、操作部２３と、記憶部２４と、を備える。なお、表示装置２０を構成する各部は、同じ筐体内に配置されていても良いし、別の筐体内に配置されていても良い。 The display device 20 includes a control device 21, a display unit 22, an operation unit 23, and a storage unit 24. In addition, each part which comprises the display apparatus 20 may be arrange | positioned in the same housing | casing, and may be arrange | positioned in another housing | casing.
　制御装置２１は、ＣＰＵ、ＲＡＭ、及びＲＯＭ等を備えたマイクロコンピュータとして構成されている。制御装置２１は、ＲＯＭに記憶されたプログラムをＲＡＭに読み出して実行することで、様々な制御を行うことができる。 The control device 21 is configured as a microcomputer including a CPU, a RAM, a ROM, and the like. The control device 21 can perform various controls by reading a program stored in the ROM into the RAM and executing it.
　 また、制御装置２１は、情報受信部２１ａと、情報送信部２１ｂと、制御部２１ｃと、を備える。情報受信部２１ａは、ＡＩＳ送受信機１７等を介してＡＩＳ信 号又はその解析結果を受信する。情報送信部２１ｂは、自船に関する情報をＡＩＳ送受信機１７へ出力し、当該ＡＩＳ送受信機１７がＡＩＳ信号等を外部へ送信 する。換言すれば、制御装置２１は、ＡＩＳを介して、ＡＩＳ信号又はその解析結果（通信機情報等）を送受信する。情報送信部２１ｂは、ＡＩＳ送受信機１７ 等を介してＡＩＳ信号を外部へ送信する。制御部２１ｃは、例えば、ＧＰＳ受信機１５から入力された自船の位置情報と、記憶部２４が記憶する海図情報と、に 基づいて、自船の位置を海図上に表示する処理を行う。また、制御部２１ｃは、ＡＩＳ送受信機１７から入力された情報に基づいて、上記の海図上に更に他船の 位置及び前記通信機情報等を表示する処理を行う。また、制御部２１ｃは、無線通信機１１に無線通信の開始を指示することができる。 Moreover, the control device 21 includes an information reception unit 21a, an information transmission unit 21b, and a control unit 21c. The information receiving unit 21a receives the AIS signal or its analysis result via the AIS transceiver 17 or the like. The information transmission unit 21b outputs information about the ship to the AIS transceiver 17, and the AIS transceiver 17 transmits an AIS signal and the like to the outside. In other words, the control device 21 transmits and receives an AIS signal or an analysis result (communication device information or the like) via the AIS. The information transmitter 21b transmits an AIS signal to the outside via the AIS transceiver 17 or the like. For example, the control unit 21c performs a process of displaying the position of the ship on the chart based on the position information of the ship that is input from the GPS receiver 15 and the chart information stored in the storage unit 24. Further, based on the information input from the AIS transmitter / receiver 17, the control unit 21c further performs a process of displaying the dredger position of the other ship and the communication device information on the above chart. In addition, the control unit 21c can instruct the wireless communication device 11 to start wireless communication.
　表示部２２は、液晶ディスプレイ等で構成されており、制御部２１ｃが作成した画像を表示画面に表示する。 The display unit 22 is composed of a liquid crystal display or the like, and displays an image created by the control unit 21c on the display screen.
　 操作部２３は、ユーザが操作を行うためのインタフェースである。操作部２３は、トラックボール、マウス、及びキーボード等の操作装置であっても良いし、表 示部２２の筐体に設けられた物理キーであっても良いし、表示部２２のタッチパネルであっても良い。例えば、ユーザが操作部２３を操作して、表示部２２に表 示された他船を選択することで、選択した他船に関する詳細な情報が表示される。 The operation unit 23 is an interface for a user to perform an operation. The operation unit 23 may be an operation device such as a trackball, a mouse, and a keyboard, may be a physical key provided on the housing of the display unit 22, or may be a touch panel of the display unit 22. May be. For example, when the user operates the operation unit 23 and selects another ship displayed on the display unit 22, detailed information regarding the selected other ship is displayed.
　記憶部２４は、表示部２２に表示するための海図情報を記憶している。記憶部２４は、フラッシュメモリ又はハードディスク等の記憶装置であっても良いし、ＳＤカード等の記憶媒体であっても良い。 The storage unit 24 stores nautical chart information to be displayed on the display unit 22. The storage unit 24 may be a storage device such as a flash memory or a hard disk, or may be a storage medium such as an SD card.
　 次に、図３から図６までを参照して、他船から通信機情報を取得して表示し、ユーザの指示に応じて通信開始処理を行う流れについて説明する。図３は、無線通 信の開始までに双方の船舶で行われる処理を示すシーケンス図であり、図４から図６は、この処理を行っている際に船舶２の表示部２２に表示される内容を示す 図である。なお、以下の説明では、船舶２が船舶３に対して無線通信を開始する場合について説明する。 Next, with reference to FIG. 3 to FIG. 6, a flow of acquiring and displaying communication device information from another ship and performing communication start processing in accordance with a user instruction will be described. FIG. 3 is a sequence diagram showing processing performed by both ships until the start of wireless communication. FIGS. 4 to 6 are displayed on the display unit 22 of the ship 2 during this processing. FIG. In the following description, a case where the ship 2 starts wireless communication with the ship 3 will be described.
　図３に示すように、 船舶３のＡＩＳ送受信機１７は、定期的又は不定期でＡＩＳ信号を不特定多数に送信する（シーケンス番号１）。上述したように船舶３が送信するＡＩＳ信号に は、船舶３のＭＭＳＩ番号、船舶３が備える無線通信機１１が対応している周波数帯域、船舶３が他の船舶と通信中であれば当該通信で使用中の周波数帯域及び 通信チャンネルが含まれる。 As shown in FIG. 3, the AIS transceiver 17 of the dredger 3 transmits an AIS signal to an unspecified number of people regularly or irregularly (sequence number 1). As described above, the AIS signal transmitted by the ship 3 includes the MMSI number of the ship 3, the frequency band supported by the wireless communication device 11 included in the ship 3, and the communication if the ship 3 is communicating with another ship. And the frequency band and communication channel used in the network.
　船舶２のＡＩＳ送受信機１７は、船舶３が送信したＡＩＳ信号を受信して解析し、制御部２１ｃ へ出力する（シーケンス番号２）。制御部２１ｃは、入力されたＡＩＳ信号の解析結果を表示部２２に表示し、通信相手の選択を受け付ける（シーケンス番号 ３）。図４は、このとき表示部２２に表示される内容を示す図である。 The AIS transceiver 17 of the ship 2 receives and analyzes the AIS signal transmitted by the ship 3, and outputs it to the control unit 21c (sequence number 2). The control unit 21c displays the analysis result of the input AIS signal on the display unit 22, and accepts the selection of the communication partner (sequence number 3). FIG. 4 is a diagram showing the contents displayed on the display unit 22 at this time.
　図４では、陸地部分に斜線を付している。また、実際 の海図には様々な情報（水深、浮標等）が表示されるが、図面を見易くするためにこれらの表示を省略している。図４には、自船位置シンボル３１と、ＡＩＳシ ンボル３２～３４と、が表示されている。自船位置シンボル３１は、自船（船舶２）の位置を示している。ＡＩＳシンボル３２～３４は、ＡＩＳ信号を解析する ことで得られた他船の位置及び船首方位等を示している。なお、ＡＩＳシンボル３２が船舶３に対応するものとする。 In Fig. 4, the land portion is hatched. In addition, various information (water depth, buoy, etc.) is displayed on the actual nautical chart, but these are omitted for the sake of clarity. In FIG. 4, a ship position symbol 31 and AIS symbols 32 to 34 are displayed. The own ship position symbol 31 indicates the position of the own ship (ship 2). The AIS symbols 32 to 34 indicate the position and heading of the other ship obtained by analyzing the AIS signal. It is assumed that the AIS symbol 32 corresponds to the ship 3.
　本実施 形態では、このＡＩＳシンボル３２～３４の近傍に、周波数帯域情報４１が表示される。周波数帯域情報４１には、ＡＩＳシンボル３２～３４が示す船舶が備え る無線通信機１１が対応可能な周波数帯域と、この周波数帯域を使用して通信中か否かと、が示されている。例えばＡＩＳシンボル３２で示す船舶（船舶３） は、ＨＦとＶＨＦに対応可能であり、何れの周波数帯域でも通信中でないことが示されている。このように、周波数帯域情報４１は、該当する船舶の近傍に表示 される。換言すれば、通信機情報に含まれる位置情報に基づいて決定された位置に周波数帯域情報４１が表示される。 In the present embodiment, frequency band information 41 is displayed in the vicinity of the AIS symbols 32 to 34. The frequency band information 41 indicates a frequency band that can be supported by the wireless communication device 11 provided in the ship indicated by the AIS symbols 32 to 34 and whether or not communication is being performed using this frequency band. For example, it is shown that the ship (ship 3) dredge indicated by the AIS symbol 32 is compatible with HF and VHF and is not communicating in any frequency band. Thus, the frequency band information 41 is displayed near the corresponding ship. In other words, the frequency band information 41 is displayed at a position determined based on the position information included in the communication device information.
　なお、 周波数帯域情報４１の表示態様は任意であり適宜変更することができる。例えば、自船が対応可能であって他船が対応不能な周波数帯域については、非表示では なく、他の周波数帯域と異なる表示態様（グレーアウト等）で表示しても良い。あるいは、自船が対応不能であって他船が対応可能な周波数帯域について、他の 周波数帯域と異なる表示態様（グレーアウト等）で表示しても良い。また、ＡＩＳシンボル３２～３４が選択されて初めて周波数帯域情報４１が表示されても良 いし、周波数帯域情報４１を表示するモードを有し、当該モードが選択されて初めて周波数帯域情報４１が表示されても良い。 It should be noted that the display mode of the soot frequency band information 41 is arbitrary and can be changed as appropriate. For example, the frequency band that can be handled by the ship but cannot be handled by other ships may be displayed in a display mode (grayed out) different from the other frequency bands without being hidden. Alternatively, the frequency band that cannot be handled by the ship and that can be handled by other ships may be displayed in a display mode (grayed out or the like) different from other dredging frequency bands. Also, it is acceptable that the frequency band information 41 is displayed for the first time after the AIS symbols 32 to 34 are selected, and there is a mode for displaying the frequency band information 41. The frequency band information 41 is displayed only after the mode is selected. May be.
　 従来は、周波数帯域情報４１は表示されていなかったため、ある周波数帯域で他船に対して通信開始処理を行い、応答があって初めてこの他船とその周波数帯域 で通信可能であることを把握していた。そのため、他船と通信可能であるか把握するまでに時間及び手間が掛かっていた。この点、本実施形態では、表示部２２ に周波数帯域情報４１が表示されるので、他船と通信可能であるかを瞬時に把握できる。 Conventionally, since the frequency band information 41 has not been displayed, a communication start process is performed for another ship in a certain frequency band, and it is understood that communication with this other ship can be made in this frequency band only after there is a response. It was. For this reason, it takes time and effort to determine whether communication with other ships is possible. In this regard, in the present embodiment, since the frequency band information 41 is displayed on the display unit 22, it is possible to instantly grasp whether communication with other ships is possible.
　また、他船と無線通信する目的の１ つとして、他船との衝突をスムーズに回避するということが挙げられる。そのため、例えば自船と衝突の可能性がある他船については、通信可能か否かを特に把 握したいというニーズがある。この点、本実施形態では、他船の位置及び船首方位がグラフィカルに表示されているので、自船と衝突の可能性がある他船及びこ の他船と通信可能であるかを素早く把握できる。 Also, one of the purposes of wireless communication with other ships is to avoid collisions with other ships smoothly. Therefore, there is a need to particularly grasp whether or not communication is possible for other ships that may collide with the ship. In this respect, in this embodiment, the position and heading of the other ship are graphically displayed, so that it is possible to quickly grasp whether the other ship that may collide with the own ship and the other ship can communicate with this ship. .
　また、図４では、互いに通信中の船舶同士は、線で接続されることで、互い に通信中であることが示されている。なお、別の表示態様により、互いに通信中であることを示しても良い。例えば、通信中の船舶同士を同じ色で着色しても良 い。この線の近傍には、使用通信チャンネル情報４２が表示されている。 Further, in FIG. 4, it is shown that ships that are communicating with each other are communicating with each other by being connected with a line. In addition, you may show that it is communicating with each other by another display mode. For example, it is okay to color the ships in communication with the same color. In the vicinity of this line, used communication channel information 42 is displayed.
　使用通信チャンネル情報４２は、通信中の船舶同士 が使用している周波数帯域及び通信チャンネルを示す情報である。例えばＡＩＳシンボル３３，３４で示す船舶は、ＶＨＦのＣＨ６０を使用して互いに無線通信 を行っている。このように使用通信チャンネル情報４２を表示することで、自船（船舶２）の近傍で使用している周波数帯域及び通信チャンネルを把握すること ができるので、混信及びノイズが発生しないように通信チャンネルを選択することが可能となる。 The used communication channel information 42 is information indicating a frequency band and a communication channel used by ships in communication. For example, the ships indicated by the AIS symbols 33 and 34 use the VHF CH60 to perform radio communication with each other. By displaying the used communication channel information 42 in this way, it is possible to grasp the frequency band and communication channel used in the vicinity of the ship (ship 2), so that the communication channel does not generate interference and noise. Can be selected.
　ユーザは、操作部２３を操 作して、例えばＡＩＳシンボル３２～３４をクリック又はダブルクリックすることで、無線通信の通信相手として選択することができる。制御部２１ｃは、ユー ザの選択を受け付け、受け付けた通信相手に応じて適切な周波数帯域及び通信チャンネルを求める（シーケンス番号４）。具体的には、制御部２１ｃは、自船 （船舶２）と他船（船舶３）で共通して対応している周波数帯域を選択する。そして、制御部２１ｃは、周囲で同じ周波数帯域を使用して通信が行われている場 合、他の船舶が使用中の通信チャンネルとは周波数の差が大きくなるように通信チャンネルを求める。 The user can select a wireless communication partner by operating the operation unit 23 and clicking or double-clicking the AIS symbols 32 to 34, for example. The control unit 21c accepts the user's selection and obtains an appropriate frequency band and communication channel according to the accepted communication partner (sequence number 4). Specifically, the control unit 21c selects a frequency band corresponding to both the own ship (the ship 2) and the other ship (the ship 3). And the control part 21c calculates | requires a communication channel so that the difference of a frequency may become large, when communication is performed using the same frequency band in the circumference | surroundings and the communication channel which other ships are using.
　また、制御部２１ｃ は、ユーザが無線通信の通信相手を選択した場合、図５に示すように、通信開始ポップアップウインドウ４３を表示してユーザの選択（指示）を受け付ける。通 信開始ポップアップウインドウ４３には、選択した通信相手（本実施形態では船舶３（ＡＩＳシンボル３２））のＭＭＳＩ番号、上記で求めた周波数帯域及び通 信チャンネル、及びこの条件で通信開始処理を行うか否かを選択する項目が表示される。このとき、無線通信を行う無線通信機１１を表示しても良い。また、選 択された相手と通信可能な無線通信機１１が複数存在する場合、ユーザに選択させる表示を行っても良い。 Further, when the user selects a communication partner for wireless communication, the control unit 21c displays a communication start pop-up window 43 and accepts the user's selection (instruction) as shown in FIG. In the communication start pop-up window 43, the communication start processing is performed with the MMSI number of the selected communication partner (in this embodiment, the ship 3 (AIS symbol 32)), the frequency band and communication channel obtained above, and these conditions. An item for selecting whether or not is displayed. At this time, the wireless communication device 11 that performs wireless communication may be displayed. Further, when there are a plurality of wireless communication devices 11 that can communicate with the selected partner, a display that allows the user to select may be performed.
　ユーザが通信開始 ポップアップウインドウ４３の「Ｙｅｓ」を選択した場合、制御部２１ｃはユーザの指示を受け付け（シーケンス番号５）、無線通信を開始する準備を行う。具 体的には、求めた周波数帯域で無線通信を行う無線通信機１１（本実施形態では第２無線通信機１１ｂ）に対して、無線通信を開始する指示、船舶３のＭＭＳＩ 番号、使用する周波数帯域及び通信チャンネル等（まとてめ設定情報と称する）を出力する。第２無線通信機１１ｂは、この設定情報に基づいて、船舶３に対し て、通信開始処理を行う（シーケンス番号６）。なお、ユーザは、通信開始ポップアップウインドウ４３の「Ｎｏ」を選択し、希望する周波数帯域及び通信チャ ンネルを選択して無線通信の開始を指示しても良い。 When the user selects “Yes” in the communication start pop-up window 43, the control unit 21c accepts the user instruction (sequence number 5) and prepares to start wireless communication. Specifically, for the wireless communication device 11 (second wireless communication device 11b in this embodiment) that performs wireless communication in the obtained frequency band, an instruction to start wireless communication, the MMSI serial number of the ship 3, and the use The frequency band, communication channel, etc. (collectively referred to as setting information) are output. Based on this setting information, the second wireless communication device 11b visits the ship 3 and performs communication start processing (sequence number 6). The user may select “No” in the communication start pop-up window 43, select the desired frequency band and communication channel, and instruct the start of wireless communication.
　船舶３の無線通信機１１は、この処理を受けて無線通信を確立する処理 を行い、船舶２の第２無線通信機１１ｂに対して応答を行う（シーケンス番号７）。以上により、船舶２と船舶３の間で無線通信を行うことができる。このと き、図６に示すように、自船（船舶２）と他船（船舶３）が線で接続されるとともに、使用通信チャンネル情報４２が表示される。 The wireless communication device 11 of the ship 3 receives this processing and performs a process to establish wireless communication, and makes a response to the second wireless communication device 11b of the ship 2 (sequence number 7). As described above, wireless communication can be performed between the ship 2 and the ship 3. At this time, as shown in FIG. 6, the own ship (ship 2) and the other ship (ship 3) are connected by a line, and used communication channel information 42 is displayed.
　 以上に説明したように、本実施形態の表示装置２０は、情報受信部２１ａと、表示部２２と、制御部２１ｃと、を備える。情報受信部２１ａは、外部の船舶が備 える無線通信機１１（外部無線通信機）の通信機能及び通信状態を特定するための情報である通信機情報を受信する。表示部２２は、船舶及び当該船舶の通信機 情報を表示する。制御部２１ｃは、表示部２２に表示された船舶の選択を受け付け、選択された船舶の通信機情報に基づいて当該船舶との無線通信の開始を指示 する。 As described above, the display device 20 of the present embodiment includes the information receiving unit 21a, the display unit 22, and the control unit 21c. The information receiving unit 21a receives communication device information that is information for specifying the communication function and communication state of the wireless communication device 11 (external wireless communication device) provided by an external ship. The display unit 22 displays the ship and the communication device information of the ship. The control unit 21c receives the selection of the ship displayed on the display unit 22, and instructs the start of wireless communication with the ship based on the communication device information of the selected ship.
　これにより、他船の無線通信機１１の通信機能（対応している周波数帯域等）及び通信状態（通信中か否か等）を取得 して表示するため、他船の無線通信機１１と無線通信が可能か否かを短い時間で把握することができる。また、無駄な通信開始処理が行われなくなるので、ユー ザの手間を軽減できる。 Thereby, in order to obtain and display the communication function (corresponding frequency band, etc.) and the communication state (whether communication is in progress, etc.) of the radio communication device 11 of the other ship, Whether or not communication is possible can be grasped in a short time. In addition, since unnecessary communication start processing is not performed, the user's trouble can be reduced.
