Abstract

Disclosed is a device which can make pedestrians aware of approaching vehicles. A vehicle mounted device (2), containing an IC tag (9), is positioned in cars or other vehicles. A detection device (1), containing an internal RFID reader module (4), is carried by pedestrians. If the RFID reader module (4) recognises the presence of an IC tag (9), a processor (6) judges that a vehicle is approaching the pedestrian and sends a warning signal to a mobile telephone or similar through a communication unit (7). The mobile telephone then informs the user of the approaching vehicle through a ringtone or vibration, thus preventing collisions between pedestrians and vehicles. Furthermore, due to the use of an IC tag in the vehicle mounted device (2) this system is inexpensive and easy to popularise.

　自動車が背後から近づいてきたことを歩行者が認識できておらず、また、自動車の運転手も注意をしていなかった等の理由により、自動車と歩行者とが接触事故を起こすことがある。特に、自動車がモータで駆動されるようになることにより、自動車自体が発する騒音が少なくなり、通行人がより気づき難くなる傾向にある。また、自動車側では、車内にテレビを設置したり、裏道等でカーナビゲーションを見ていたり、携帯電話を操作していたりすると、周囲の歩行者に対して注意が散漫になる傾向がある。 * A pedestrian may not be aware that the car is approaching from behind, and the car driver may not be aware of it, causing a contact accident between the car and the pedestrian. In particular, when an automobile is driven by a motor, noise generated by the automobile itself is reduced, and a passer-by tends to be more difficult to notice. On the automobile side, attention tends to be distracted to surrounding pedestrians when a television is installed in the car, when a car navigation is seen on a back road or when a mobile phone is operated.
　このように自動車と歩行者との接触事故を防止する発明としては、特許文献１に開示されているような技術が知られている。この発明は、歩行者のもつ携帯電話の電波を利用して歩行者の存在を認識するものである。 As such an invention for preventing a contact accident between a car and a pedestrian, a technique disclosed in Patent Document 1 is known. The present invention recognizes the presence of a pedestrian using radio waves of a mobile phone held by the pedestrian.

（実施の形態１）
　図１は、この発明の実施の形態1にかかる車両認識システムを示す概念図である。図２は、車両認識システムの使用状態を示す説明図である。図３は、図１に示した車両認識システムの構成図である。この車両認識システム１００は、歩行者（ユーザ）９０が携帯する検出装置１と、車両９１に搭載する車載器２とから構成され、これら検出装置１と車載器２とを相対認識するものである。 (Embodiment 1)
FIG. 1 is a conceptual diagram showing a vehicle recognition system according to Embodiment 1 of the present invention. FIG. 2 is an explanatory diagram showing a use state of the vehicle recognition system. FIG. 3 is a configuration diagram of the vehicle recognition system shown in FIG. The vehicle recognition system 100 includes a detection device 1 carried by a pedestrian (user) 90 and an in-vehicle device 2 mounted on a vehicle 91, and recognizes the detection device 1 and the in-vehicle device 2 relative to each other. .
　検出装置１は、歩行者９０が携帯しやすい、例えばポケットに収納できる程度の大きさの筐体３に、無線通信手段であるFRID（Radio Frequency IDentification）リーダモジュール４と、RFIDリーダモジュール４に接続したアンテナ５と、RFIDリーダモジュール４からの信号に対して所定の処理を行う処理部６と、携帯電話や携帯ゲーム機との通信を行う通信部７と、電源８とを収容した構成である。RFIDリーダモジュール４は、所定の無線周波数の電波により後述する車載器２のIC（Integrated Circuit）タグ９との間で無線通信を行うものであり、通信内容のエンコードやデコードや送受信信号を変換するための制御部（図示省略）を備えている。アンテナ５は、前記制御部に接続され且つRFIDリーダモジュール４の基板上に導体パターンとしてループ状に形成される（図示省略）。 The detection device 1 is connected to a radio communication means FRID (Radio Frequency IDentification) reader module 4 and an RFID reader module 4 in a housing 3 that is easy to carry by a pedestrian 90, for example, large enough to be stored in a pocket. The antenna 5, the processing unit 6 that performs predetermined processing on the signal from the RFID reader module 4, the communication unit 7 that communicates with a mobile phone or a portable game machine, and a power source 8 are accommodated. . The RFID reader module 4 performs wireless communication with an IC (Integrated Circuit) tag 9 of the vehicle-mounted device 2 to be described later using radio waves of a predetermined radio frequency, and encodes and decodes communication contents and converts transmission / reception signals. A control unit (not shown). The antenna 5 is connected to the controller and is formed in a loop shape as a conductor pattern on the substrate of the RFID reader module 4 (not shown).
　検出装置１の通信可能範囲は、下記アクティブ型のICタグ９により数１０ｍに設定されている。前記処理部６は、RFIDリーダモジュール４からの信号の変化に基づいて車両の接近を後述する手順により判断する。また、ユーザ側で特定した車両が近づいているか否かを判断する。 The communicable range of the detection device 1 is set to several tens of meters by the active type IC tag 9 below. The processing unit 6 determines the approach of the vehicle based on a change in the signal from the RFID reader module 4 according to a procedure described later. Further, it is determined whether or not the vehicle specified on the user side is approaching.
　前記通信部７は、携帯電話、携帯音楽プレーヤー、携帯ゲーム機（例えば、ニンテンドーDS：任天堂株式会社登録商標）等の携帯電子機器との通信を行うものであり、例えば、ブルートゥース（Bluetooth）用の通信部１０と、IEEE 802.11規格に準じた無線LANによる通信部１１とを備える。携帯電話や携帯ゲーム機は、これらの通信方式に対応した機種でなければならない。なお、これらは同じ２．４GHｚの周波数で無線通信を行うため、切換部１２によりユーザが携帯電話で用いるか或いは携帯ゲーム機で用いるかを選択する。前記電源８は、前記RFIDリーダモジュール４、処理部６および通信部７に対して電力の供給を行うものであり、一次電池または二次電池からなる。 The communication unit 7 communicates with a portable electronic device such as a mobile phone, a portable music player, a portable game machine (for example, Nintendo DS: registered trademark of Nintendo Co., Ltd.), for example, for Bluetooth (Bluetooth). A communication unit 10 and a communication unit 11 using a wireless LAN conforming to the IEEE 802.11 standard are provided. Mobile phones and portable game machines must be models that support these communication methods. Since these perform wireless communication at the same frequency of 2.4 GHz, the switching unit 12 selects whether the user uses a mobile phone or a mobile game machine. The power source 8 supplies power to the RFID reader module 4, the processing unit 6, and the communication unit 7, and is composed of a primary battery or a secondary battery.
　車載器２は、自動車９１のシガーソケットに差し込むシガープラグ２０を備えた筐体２１内に、アクティブ型のICタグ９と、シガープラグから供給される電力を所定の電流電圧に変換する変換器２２とを内蔵している。なお、電源として電池を用いる場合、筐体２１はシガープラグ２０及び変換器２２を必要としない。電池を電源とする場合、自転車等の発電機やバッテリーを装備していない車両にも搭載できる。ICタグ９は安価に製造できるので、車両側の所有者も購入しやすいため、普及させやすい利点がある。 The vehicle-mounted device 2 includes an active IC tag 9 and a converter 22 that converts electric power supplied from the cigar plug into a predetermined current voltage in a housing 21 having a cigar plug 20 to be inserted into a cigar socket of an automobile 91. And built-in. In addition, when using a battery as a power supply, the housing | casing 21 does not require the cigar plug 20 and the converter 22. FIG. When the battery is used as a power source, it can be mounted on a bicycle generator or a vehicle not equipped with a battery. Since the IC tag 9 can be manufactured at a low cost, the owner on the vehicle side can easily purchase it.
　ICタグ９には、車両の固有情報が記憶されている。例えば、普通車、軽自動車、トラック等の自動車の種別である。また、二輪車に用いる場合、ICタグ９には、大型バイク、原付、自転車等の種別が記憶される。当該車両の固有情報は、販売店でICタグ９に書き込むようにするのが好ましい。例えば、トラックのユーザが当該車載器２を購入した場合、販売店に依頼してトラックの情報を書き込んでもらうようにする。なお、予め全車両分の情報を記憶した車載器２を用意して販売するようにしても良い。 The IC tag 9 stores vehicle specific information. For example, it is a type of automobile such as a normal car, a light car, and a truck. When used in a two-wheeled vehicle, the IC tag 9 stores types such as large motorcycles, mopeds, and bicycles. The vehicle specific information is preferably written in the IC tag 9 at the store. For example, when a truck user purchases the vehicle-mounted device 2, he / she asks a dealer to write the track information. In addition, you may make it prepare and sell the vehicle equipment 2 which memorize | stored the information for all the vehicles beforehand.
　次に、この発明の車両認識システム１００の動作を説明する。図４は、この車両認識システム１００の動作を示すフローチャートである。検出装置１の処理部６は、一定時間毎（例えば０．１秒毎）に車載器２が通信可能範囲３０内にあるか否かを判別する（ステップ１）。すなわち、通信可能範囲３０内に車載器２に搭載されているICタグ９が存在すれば、このICタグ９の固有情報を認識し続け、車両が動いていないと判断する。続いて、通信可能範囲３０内にICタグ９が存在していない状態から、ICタグ９が存在する状態になった場合（ステップ１～２）、その回数をカウントし（ステップ３）、所定のN回数（例えばN=３回）まで当該処理を行う（ステップ４）。 Next, the operation of the vehicle recognition system 100 of the present invention will be described. FIG. 4 is a flowchart showing the operation of the vehicle recognition system 100. The processing unit 6 of the detection device 1 determines whether or not the vehicle-mounted device 2 is within the communicable range 30 at regular time intervals (for example, every 0.1 second) (step 1). That is, if the IC tag 9 mounted on the vehicle-mounted device 2 exists in the communicable range 30, it continues to recognize the unique information of the IC tag 9 and determines that the vehicle is not moving. Subsequently, when the IC tag 9 is present from the state where the IC tag 9 does not exist within the communicable range 30 (steps 1 and 2), the number of times is counted (step 3), The process is performed up to N times (for example, N = 3 times) (step 4).
所定回数だけICタグ９の存在が確認された場合、車載器２を搭載した車両９１が接近していると判断し（ステップ５）、通信部７により携帯電話または携帯ゲーム機に所定の信号を送信する（ステップ６）。携帯電話、携帯音楽プレーヤーまたは携帯ゲーム機では、予め定められたアナウンス、アラーム音、バイブレーション又は画面表示等により、車両９１の接近をユーザに報知する。なお、前記ステップ２において、ICタグ９が通信可能範囲３０に存在しなくなった場合は、車両９１が遠ざかるものと判断し、ステップ１に戻る。 When the presence of the IC tag 9 is confirmed a predetermined number of times, it is determined that the vehicle 91 equipped with the vehicle-mounted device 2 is approaching (step 5), and a predetermined signal is sent to the mobile phone or the portable game machine by the communication unit 7. Transmit (step 6). In a mobile phone, a portable music player, or a portable game machine, the approach of the vehicle 91 is notified to the user by a predetermined announcement, alarm sound, vibration, screen display, or the like. If the IC tag 9 no longer exists in the communicable range 30 in step 2, it is determined that the vehicle 91 is moving away, and the process returns to step 1.
なお、RFIDリーダモジュール４が常時ICタグ９を読み取る状態を維持し、ICタグ９が認識されていない状態（通信可能範囲にICタグ９が非存在の状態）から認識状態（通信可能範囲にICタグ９が存在の状態）になり、一定時間、認識状態が維持されたときに、車両９１が接近していると判断しても良い。接近判断に一定時間が必要なのは、接近した後に遠ざかることもあり、そのような場合にも接近と判断してユーザに報知すると、ユーザが混乱するためである。 Note that the RFID reader module 4 always maintains a state in which the IC tag 9 is read, and the IC tag 9 is not recognized (the IC tag 9 is not present in the communicable range) and the recognized state (the IC is in the communicable range). It may be determined that the vehicle 91 is approaching when the tag 9 is present) and the recognition state is maintained for a certain period of time. The reason why a certain time is required for the approach determination is that the user may move away after approaching, and in such a case, if the user is determined to approach and is notified to the user, the user is confused.
　上記ステップ５において、前記処理部６は、車両９１の種類をICタグ９の情報から判別する。ICタグ９には、上記のように車両９１の種別が書き込まれている。処理部６は、RFIDリーダモジュール４によりICタグ９の情報を読み出し、どの種類の車両９１が接近しているのか判断する。そして、判断の結果を、通信部７によりユーザの携帯電話または携帯ゲーム機に送信する。また、前記選択部１３では、報知対象とする車両９１を選択する。即ち、自転車の接近は報知が不要で、自動車のみにしたい場合は、当該選択部１３にてユーザが自転車を除外しておけば、処理部６は、自転車が接近した情報を通信部７に送らない。 In step 5 described above, the processing unit 6 determines the type of the vehicle 91 from the information of the IC tag 9. The type of the vehicle 91 is written in the IC tag 9 as described above. The processing unit 6 reads information of the IC tag 9 by the RFID reader module 4 and determines which type of vehicle 91 is approaching. Then, the result of the determination is transmitted to the user's mobile phone or portable game machine by the communication unit 7. The selection unit 13 selects a vehicle 91 to be notified. That is, when the approach of the bicycle does not need to be notified and only the automobile is desired, if the user excludes the bicycle in the selection unit 13, the processing unit 6 sends information on the approach of the bicycle to the communication unit 7. Absent.
　図５は、携帯電話の画面上の表示例を示す説明図である。携帯電話３１のユーザは、道路を歩行しながらメール文章を入力している場合、その入力に集中し、周囲に気を配ることができない。このため、画面３２の最上位に警告３３を表示させる。例えば「車両が近づいています」等の文章や、車両９１の絵を表示する。また、車両９１の種別についても、画面３２上に表示できる。例えば「トラックが接近しています」やトラックの絵を表示する。これらの表示内容については、検出装置１からその都度送信してもよいし、携帯電話３１に記憶させておき、検出装置１からの信号に基づいて表示させるようにしても良い。 FIG. 5 is an explanatory diagram showing a display example on the screen of the mobile phone. When the user of the mobile phone 31 is inputting e-mail text while walking on the road, the user concentrates on the input and cannot pay attention to the surroundings. For this reason, a warning 33 is displayed at the top of the screen 32. For example, a sentence such as “the vehicle is approaching” or a picture of the vehicle 91 is displayed. Further, the type of the vehicle 91 can also be displayed on the screen 32. For example, “Track is approaching” or a picture of the track is displayed. These display contents may be transmitted from the detection device 1 each time, or may be stored in the mobile phone 31 and displayed based on a signal from the detection device 1.
　図６は、携帯ゲーム機の画面上の表示例を示す説明図である。携帯ゲーム機３４は、子供が道路上で操作している場合があり、携帯電話同様に周囲への注意が散漫になっている。このため、画面３５上の最上位に警告３６を表示させる。例えば、「くるまですよ！」等の文章や、車両９１の絵などを表示する。また、車両９１の種別についても、画面３５上に表示できる。例えば「自転車が接近しています」や自転車の絵を表示する。これらの表示内容については、検出装置１からその都度送信してもよいし、携帯ゲーム機３４に記憶させておき、検出装置１からの信号に基づいて表示させるようにしても良い。 FIG. 6 is an explanatory diagram showing a display example on the screen of the portable game machine. The portable game machine 34 may be operated by a child on the road, and attention to the surroundings is distracting like a mobile phone. For this reason, a warning 36 is displayed at the top on the screen 35. For example, a text such as “It is a car!” Or a picture of the vehicle 91 is displayed. The type of the vehicle 91 can also be displayed on the screen 35. For example, “bicycle is approaching” or a bicycle picture is displayed. These display contents may be transmitted from the detection device 1 each time, or may be stored in the portable game machine 34 and displayed based on a signal from the detection device 1.
　なお、検出装置１自体に報知手段を追加しても良い。報知手段としては、スピーカー、バイブレータ及びLED等の発光素子の全て又はいずれかを用いるのが良い。特に、バイブレータや発光素子は耳の不自由な歩行者に好適であり、目が不自由な歩行者には、スピーカーやバイブレータが好適である。 In addition, you may add an alerting | reporting means to the detection apparatus 1 itself. As the notification means, it is preferable to use all or any of light emitting elements such as a speaker, a vibrator, and an LED. In particular, the vibrator and the light-emitting element are suitable for a deaf pedestrian, and for a deaf pedestrian, a speaker and a vibrator are suitable.
　以上、この発明の車両認識システム１００によれば、歩行者９０が自動車などの車両９１の接近を相対的に知ることができるので、車両９１との接触事故を未然に防止できる。また、歩行者９０が持ち歩き且つ最も手に触れることが多い携帯電話３１や携帯ゲーム機３４を報知手段として用いることにより、より歩行者９０に注意を促すことができる。特に、若者や子供は、携帯電話、携帯音楽プレーヤー、携帯ゲーム機を使いながら歩いたり、道に留まっていたりするため、これらの機器自体から報知することが最も効果的といえる。 As described above, according to the vehicle recognition system 100 of the present invention, since the pedestrian 90 can relatively know the approach of the vehicle 91 such as an automobile, a contact accident with the vehicle 91 can be prevented in advance. In addition, the pedestrian 90 can be more alerted by using the mobile phone 31 or the portable game machine 34 that the pedestrian 90 carries and touches most frequently as the notification means. In particular, since young people and children walk and stay on the road while using mobile phones, portable music players, and portable game machines, it can be said that it is most effective to make notifications from these devices themselves.
　図７は、この実施の形態１の車両認識システムの別の例を示す構成図である。この検出装置１４は、携帯電話や携帯ゲーム機に信号を送信して報知するのではなく、通信部の代わりに、検出装置１自体に報知手段１５を設けた点が異なる。その他の構成は上記同様である。この報知手段１５としては、スピーカー、バイブレータ及びLED等の発光素子の全て又はいずれかを用いるのが良い。このようにすれば、検出装置１のみを携帯することで、車両９１の接近を判断できる。 FIG. 7 is a configuration diagram showing another example of the vehicle recognition system of the first embodiment. The detection device 14 is different from the first embodiment in that a notification means 15 is provided in the detection device 1 itself instead of transmitting a signal to a mobile phone or a portable game machine. Other configurations are the same as described above. As the notification means 15, it is preferable to use all or any of light emitting elements such as a speaker, a vibrator, and an LED. In this way, the approach of the vehicle 91 can be determined by carrying only the detection device 1.
　また、上記検出装置１を携帯電話、携帯音楽プレーヤーまたは携帯ゲーム機と一体化させても良い。その場合、通信部７は不要であり、携帯電話等の処理部に直に接続すればよい。 Further, the detection device 1 may be integrated with a mobile phone, a portable music player, or a portable game machine. In this case, the communication unit 7 is not necessary and may be directly connected to a processing unit such as a mobile phone.
（実施の形態２）
　図８は、この発明の実施の形態２に係る停車地点認識システムを示す構成図である。この停車地点認識システム２００は、検出装置２０１と、地点設置器２０２とから構成され、検出装置２０１と地点設置器２０２とを相対認識するものである。以下、検出装置２０１を携帯電話２０３に内蔵し、且つ、電車の各駅に地点設置器２０２を設置した場合を例に挙げて説明する。携帯電話２０３を例に挙げたのは、殆どのユーザが屋外での駅の検索には携帯電話を用いるためである。 (Embodiment 2)
FIG. 8 is a block diagram showing a stop point recognition system according to Embodiment 2 of the present invention. The stop point recognition system 200 includes a detection device 201 and a spot installation device 202, and recognizes the detection device 201 and the spot installation device 202 relative to each other. Hereinafter, a case where the detection device 201 is built in the mobile phone 203 and the point installation device 202 is installed at each station of the train will be described as an example. The mobile phone 203 is taken as an example because most users use a mobile phone to search for a station outdoors.
　検出装置２０１は、携帯電話２０３の筐体に内蔵されており、無線通信手段であるRFIDリーダモジュール４と、RFIDリーダモジュール４に接続したアンテナ５と、RFIDリーダモジュール４からの信号に対して所定の処理を行う処理部６と、携帯電話２０３本体の処理部２０４とのインタフェース２０５とを備えた構成である。RFIDリーダモジュール４は、所定の無線周波数の電波により後述する地点設置器２０２のICタグ９との間で無線通信を行うものであり、通信内容のエンコードやデコードや送受信信号を変換するための制御部（図示省略）を備えている。アンテナ５は、前記制御部に接続され且つRFIDリーダモジュール４の基板上に導体パターンとしてループ状に形成される（図示省略）。 The detection device 201 is built in the housing of the mobile phone 203, and the RFID reader module 4 that is a wireless communication means, the antenna 5 connected to the RFID reader module 4, and a signal from the RFID reader module 4 are predetermined. The processing unit 6 that performs the above processing and the interface 205 with the processing unit 204 of the mobile phone 203 main body are provided. The RFID reader module 4 performs wireless communication with an IC tag 9 of a point installation device 202, which will be described later, using radio waves of a predetermined radio frequency, and controls for encoding and decoding communication contents and converting transmission / reception signals. Part (not shown). The antenna 5 is connected to the controller and is formed in a loop shape as a conductor pattern on the substrate of the RFID reader module 4 (not shown).
　検出装置２０１の通信可能範囲は、下記アクティブ型のICタグ９により数１０ｍに設定されている。前記処理部６は、RFIDリーダモジュール４からの信号に基づいて目的駅への到着を後述する手順により判断する。前記RFIDリーダモジュール４、処理部６等は、携帯電話２０３の電源から電力の供給を受ける。 The communicable range of the detection device 201 is set to several tens of meters by the active IC tag 9 below. The processor 6 determines arrival at the destination station based on a signal from the RFID reader module 4 according to a procedure described later. The RFID reader module 4, the processing unit 6, etc. are supplied with power from the power source of the mobile phone 203.
　また、検出装置２０１には、駅の固有情報を記憶した記憶部２０６と、駅を選択する選択部２０７とが設けられている。記憶部２０６は、携帯電話２０３のメモリの記憶容量の一部を検出装置２０１用に割り当てるようにするのが良い。駅の固有情報は、インターネット経由で本システムの専用のサーバ２０８から一括ダウンロードして取得し、前記記憶部２０６に記憶しておく。サーバ２０８に格納されている駅の固有情報は、定期的に更新されるので、ユーザは任意の時期に更新を行うようにする。 Also, the detection device 201 is provided with a storage unit 206 that stores unique information of a station and a selection unit 207 that selects a station. The storage unit 206 may allocate a part of the storage capacity of the memory of the mobile phone 203 to the detection device 201. Station specific information is acquired by batch downloading from the dedicated server 208 of the present system via the Internet and stored in the storage unit 206. Since the station-specific information stored in the server 208 is updated periodically, the user performs an update at an arbitrary time.
　地点設置器２０２は、筐体内に、アクティブ型のICタグ９を内蔵している。電力は、１００V電源または太陽電池パネル等から供給する。ICタグ９には、駅の固有情報が記憶されている。例えば、駅名や駅に近い公共施設や商業施設等である。設置場所は、駅のホームが好ましい。 The point installation device 202 incorporates an active type IC tag 9 in a housing. Electric power is supplied from a 100 V power source or a solar cell panel. The IC tag 9 stores station specific information. For example, a station name or a public facility or commercial facility near the station. The installation place is preferably a station platform.
　次に、この発明の停車地点認識システム２００の動作を説明する。図９は、停車地点認識システムの使用状態を示す説明図である。図１０は、この停車地点認識システムの動作を示すフローチャートである。ユーザは、予め各駅の固有情報をインターネット経由で専用のサーバ２０８からダウンロードし、記憶部２０６に記憶させておく。例えば、ユーザが所定の駅に到達するまで本を読みたいと考えた場合、検出装置２０１の機能をオンにし、携帯電話２０３から所定の駅の名前を入力する（ステップ１）。 Next, the operation of the stop point recognition system 200 of the present invention will be described. FIG. 9 is an explanatory diagram showing a use state of the stop point recognition system. FIG. 10 is a flowchart showing the operation of the stop point recognition system. The user previously downloads the unique information of each station from the dedicated server 208 via the Internet and stores it in the storage unit 206. For example, when the user wants to read a book until reaching a predetermined station, the function of the detection device 201 is turned on, and the name of the predetermined station is input from the mobile phone 203 (step 1).
　選択部２０７は、この入力された目的駅及びその一つ前の駅および一つ後の駅を自動的に選択して、各駅の固有情報を記憶部２０６から抽出し（ステップ２）、一時的に処理部６のメモリに記憶する。なお、目的駅の前後の駅を抽出するのは、目的駅に到着したことをユーザが知ってから下車準備をしても間に合わないことがあるからである。例えば、満員電車や多くの荷物を持っている場合等は、下車に準備が必要であるから、目的駅の前の駅で報知されるのが好ましい。なお、後の駅を抽出したのは、山の手線等の環状線ではどちらの経路から目的駅に到達するか判らないためである。換言すれば、目的駅に到着予定である旨をユーザに報知するためである。 The selection unit 207 automatically selects the input destination station, the preceding station and the next station, and extracts the unique information of each station from the storage unit 206 (step 2), and temporarily Is stored in the memory of the processing unit 6. The reason why the stations before and after the destination station are extracted is that it may not be in time even if the user knows that the destination station has been reached and prepares to get off. For example, when a crowded train or a lot of luggage is needed, it is preferable to be notified at the station in front of the destination station because preparation is required for getting off. The reason why the later stations are extracted is that it is not known from which route the destination station is reached on the circular line such as the Yamanote line. In other words, it is for informing the user that he is arriving at the destination station.
　次に、処理部６は、駅に到着するたびに駅に設置した地点設置器２０２のICタグ９の情報を読み出し（ステップ３）、前記抽出した駅の固有情報と照合し、当該抽出した駅の固有情報と一致するまで繰り返し行う（ステップ４）。照合の結果、前記抽出した駅の固有情報と一致した場合、ユーザに目的駅の手前であることを報知するよう、携帯電話２０３の処理部２０４に命令を送る（ステップ５）。続いて、目的の駅に到着した場合、当該駅の固有の情報を読み取って目的とする駅の固有情報と照合する（ステップ６及びステップ７）。照合の結果、目的駅の固有情報と一致した場合、ユーザに目的駅であることを報知するよう、携帯電話２０３の処理部２０４に命令を送る（ステップ８）。 Next, the processing unit 6 reads the information of the IC tag 9 of the point installation device 202 installed at the station every time it arrives at the station (step 3), compares it with the extracted unique information of the station, and extracts the extracted station The process is repeated until it matches the unique information (step 4). As a result of the collation, if it matches the extracted unique information of the station, a command is sent to the processing unit 204 of the mobile phone 203 so as to notify the user that the station is in front of the target station (step 5). Subsequently, when arriving at the target station, the unique information of the station is read and collated with the unique information of the target station (steps 6 and 7). As a result of the collation, if it matches the specific information of the destination station, a command is sent to the processing unit 204 of the mobile phone 203 to notify the user that the destination station is the destination station (step 8).
　また、上記駅の固有情報には、駅の近隣の公共施設や商業施設の情報等が記憶されているので、これらの情報もあわせて読み取ることができる。駅側では、ICタグ９の内容を書き換えるためのリーダライタにより、かかる情報を地点設置器２０２のICタグ９に記憶させる。これにより、簡単に駅の固有情報の更新が行える（但し、駅名自体の情報は更新しない）。 In addition, since the information specific to the station stores information on public facilities and commercial facilities in the vicinity of the station, these information can also be read together. On the station side, the information is stored in the IC tag 9 of the point installation device 202 by a reader / writer for rewriting the contents of the IC tag 9. Thereby, the station specific information can be easily updated (however, the station name itself is not updated).
　専用のサーバ２０８が駅の固有情報を管理する。新規または既存の駅に地点設置器２０２が設置された場合には、この地点設置器２０２のICタグ９に記憶されている駅の固有情報を、管理者がサーバにアップロードし、ユーザがダウンロード可能な状態にしておく。 Dedicated server 208 manages station specific information. When the point installation device 202 is installed in a new or existing station, the administrator can upload the station specific information stored in the IC tag 9 of the point installation device 202 to the server, and the user can download it. Keep it in a proper state.
　以上、この発明の停車地点認識システム２００は、目的駅の手前の駅でユーザに目的駅が近いことを報知するため、下車準備を行う時間が取れ、降り遅れることがない。また、目的駅に到着したことも報知されるので、確実に目的駅であることを認識できる。なお、上記では携帯電話２０３に検出装置２０１を組み込んだ例を示したが、携帯ゲーム機や携帯音楽プレーヤーに組み込むようにしても良い。この場合、サーバ２０８からパーソナルコンピュータに駅の固有情報をダウンロードし、パーソナルコンピュータから当該携帯ゲーム機や携帯音楽プレーヤーのメモリに駅の固有情報を移動するようにする。 As described above, since the stop point recognition system 200 of the present invention notifies the user that the destination station is near at the station in front of the destination station, it takes time to get off and does not delay getting off. In addition, since the arrival at the destination station is also notified, it can be recognized that the destination station is reached. In addition, although the example which incorporated the detection apparatus 201 in the mobile telephone 203 was shown above, you may make it incorporate in a portable game machine or a portable music player. In this case, station specific information is downloaded from the server 208 to the personal computer, and the station specific information is moved from the personal computer to the memory of the portable game machine or portable music player.
　また、地点設置器２０２をバス停に設置しても良い。この場合、地点設置器２０２のICタグ９への電力供給は、バス停に設置した太陽発電パネルから行うようにするのが好ましい。バス停の場合であっても上記駅をバス停に置き換えて考えれば、同じことであるから、その説明を省略する。特に、地点設置器２０２が安価に製造できるため、バス停に好適である。また、地点設置器２０２のICタグ９の情報の書き換えも、バスの運転手がリーダライタを用いて行えばよい。 Alternatively, the point installation device 202 may be installed at a bus stop. In this case, power supply to the IC tag 9 of the point installation device 202 is preferably performed from a solar power generation panel installed at the bus stop. Even in the case of a bus stop, if the above station is replaced with a bus stop, the same is true, so the description thereof is omitted. In particular, since the point installation device 202 can be manufactured at low cost, it is suitable for a bus stop. In addition, the information on the IC tag 9 of the point installation device 202 may be rewritten using a reader / writer by the bus driver.
（実施の形態３）
　図１１は、この発明の実施の形態３に係る置き忘れ防止システムを示す概念図である。この置忘れ防止システム３００は、検出装置３０１とICタグ３０９とから構成される。検出装置３０１は携帯電話３０２に内蔵されている。これは、殆どのユーザが携帯電話３０２の忘れを優先的に確認する傾向にあり、且つ、ユーザに報知する手段として好適だからである。また、ICタグ３０９には、パッシブ型のものを用いる。パッシブ型のICタグ３０９は、リーダからの電波から電力を発生させるので、電源は不要である。 (Embodiment 3)
FIG. 11 is a conceptual diagram showing a misplacement prevention system according to Embodiment 3 of the present invention. This misplacement prevention system 300 includes a detection device 301 and an IC tag 309. The detection device 301 is built in the mobile phone 302. This is because most users tend to check forgetting the cellular phone 302 preferentially and are suitable as a means for notifying the user. The IC tag 309 is a passive type. The passive IC tag 309 generates power from radio waves from the reader, and thus does not require a power source.
　検出装置３０１の構造は、実施の形態２の検出装置２０１と同じである。なお、検出装置３０１の通信可能範囲は２ｍ～３ｍに設定されている。前記処理部６は、RFIDリーダモジュール４からの信号に基づいてICタグ３０９を貼り付けた物が自分の周りにあるか否かを後述する手順により判断する。前記RFIDリーダモジュール４、処理部６等は、携帯電話３０２の電源から電力の供給を受ける。 The structure of the detection device 301 is the same as that of the detection device 201 of the second embodiment. Note that the communicable range of the detection device 301 is set to 2 m to 3 m. Based on the signal from the RFID reader module 4, the processing unit 6 determines whether or not there is an object to which the IC tag 309 is attached around it by a procedure described later. The RFID reader module 4, the processing unit 6, etc. are supplied with power from the power source of the mobile phone 302.
　ユーザは、ICタグ３０９を忘れやすい物に貼り付ける。ICタグ３０９は、図１２に示すように、ICタグ３０９が中央に配置されたシール３１０として複数供給される。複数のICタグ３０９に書き込まれている固有情報は共通である。このICタグ３０９のシール３１０は複数枚が同じ台紙３１１に貼られてセット販売され、購入時に検出装置３０１でICタグ３０９の固有情報を読み取り、これを記憶部２０６に登録することで使用できるようにする。 The user attaches the IC tag 309 to something that is easy to forget. As shown in FIG. 12, a plurality of IC tags 309 are supplied as a seal 310 in which the IC tags 309 are arranged in the center. The unique information written in the plurality of IC tags 309 is common. A plurality of the stickers 310 of the IC tag 309 are affixed on the same mount 311 and sold as a set, and the unique information of the IC tag 309 is read by the detection device 301 at the time of purchase and can be used by registering it in the storage unit 206. To.
　次に、この置忘れ防止システムの動作について説明する。使用の前提として、ユーザは、ICタグ３０９が中央に配置されたシール３１０を置き忘れ防止したい物（対象物）に対して張り付けておく。また、携帯電話３０２は必ずユーザが身に付けているものとする。まず、携帯電話３０２の検出装置１をオンにし、ICタグ３０９がRFIDリーダモジュール４の通信可能範囲にあるかを常に監視する。ユーザが対象物を置き忘れた状態で対象物から離れると、RFIDリーダモジュール４との通信ができなくなるので、前記処理部６は、置き忘れが生じたものとして携帯電話３０２の処理部３０３に報知すべき旨の命令を出す。携帯電話３０２では、アナウンス、アラーム音、バイブレーション又は画面表示等によりユーザに置き忘れが生じていることを報知する。 Next, the operation of this misplacement prevention system will be described. As a premise of use, the user attaches the seal 310 with the IC tag 309 disposed in the center to an object (object) to be prevented from being left behind. Further, it is assumed that the mobile phone 302 is always worn by the user. First, the detection device 1 of the mobile phone 302 is turned on, and it is always monitored whether the IC tag 309 is within the communicable range of the RFID reader module 4. If the user leaves the object in a state where the object has been left behind, communication with the RFID reader module 4 becomes impossible. Therefore, the processing unit 6 should notify the processing unit 303 of the mobile phone 302 that the object has been left behind. An order to that effect is issued. The mobile phone 302 notifies the user that misplacement has occurred by an announcement, alarm sound, vibration, screen display, or the like.
　なお、ユーザは、ICタグ３０９を複数の対象物に貼り付けることで、様々な持ち物の置き忘れを効果的に防止できる。なお、携帯電話３０２を置き忘れてしまった場合でも、ICタグ３０９を貼り付けた対象物を持っていれば、携帯電話３０２のアラームが鳴る等によりユーザが気づくことができる。 Note that the user can effectively prevent misplacement of various belongings by attaching the IC tag 309 to a plurality of objects. Even if the mobile phone 302 is left behind, if the user has an object to which the IC tag 309 is attached, the user can be aware of the alarm of the mobile phone 302 or the like.
　以上、この発明の置き忘れ防止システム３００では、対象物を置き忘れても携帯電話３０２により報知されるので、置き忘れを防止できる。また、安価なパッシブ型のICタグ３０９をシール３１０に貼り付けて、このシール３１０を対象物に適宜貼り付けるようにしたので、ユーザが簡単にシステムを設定できる。なお、子供向けには、携帯ゲーム機に検出装置３０１を内蔵することで同様の効果が得られる。さらに、検出装置３０１を独立した筐体に内蔵してもよい（図示省略）。この場合、検出装置３０１の本体には、ユーザに対する報知手段としてスピーカー、バイブレータ及びLED等の発光素子の全て又はいずれかを用いるのが良い。処理部６がこれらの報知手段を動作させる。このようにすれば、当該本体のみを携帯することで、置き忘れ防止を図ることができる。 As described above, in the misplacement prevention system 300 according to the present invention, even if an object is misplaced, it is notified by the mobile phone 302, so that misplacement can be prevented. In addition, since an inexpensive passive IC tag 309 is attached to the seal 310 and the seal 310 is appropriately attached to the object, the user can easily set the system. For children, the same effect can be obtained by incorporating the detection device 301 in a portable game machine. Further, the detection device 301 may be built in an independent housing (not shown). In this case, all or any of light emitting elements such as a speaker, a vibrator, and an LED may be used as a notification unit for the user in the main body of the detection device 301. The processing unit 6 operates these notification means. In this way, it is possible to prevent misplacement by carrying only the main body.
