　このような料金収受システムでは、無線通信に利用する周波数帯によっては、路面や設置物等で電波が反射するなどして、料金収受の対象とする車両（以下、「対象車両」とも記載する。）以外の車両（対象車両の後続車両、他の車線を走行する車両等）との誤通信を引き起こしてしまう可能性がある。 In such a toll collection system, a vehicle targeted for toll collection (hereinafter also referred to as “target vehicle”) due to radio waves being reflected on the road surface or installations depending on the frequency band used for wireless communication. It is possible to cause erroneous communication with vehicles other than the above (vehicles following the target vehicle, vehicles traveling in other lanes, etc.).
　特許文献１には、車両検知器で車両が通信可能領域にあることを識別することで、対向車線からの通信に対し課金しないように制御する道路料金システムが提案されている。 [Patent Document 1] proposes a road charge system in which a vehicle detector identifies that a vehicle is in a communicable area so that communication from an oncoming lane is not charged.

＜第１の実施形態＞
　以下、図１Ａ～図５を参照しながら、第１の実施形態に係る料金収受システムについて詳細に説明する。 <First Embodiment>
Hereinafter, the fee collection system according to the first embodiment will be described in detail with reference to FIGS. 1A to 5.
（料金収受システムの全体構成）
　図１Ａ、図１Ｂは、第１の実施形態に係る料金収受システムの全体構成を示す図である。
　図１に示す料金収受システム１は、例えば、有料道路の料金所（入口料金所または出口料金所）に設置される。図１に示すように、料金収受システム１は、料金所の車線Ｌと、当該車線Ｌの路側に敷設されたアイランドＩに設置されている。
　なお、以下の説明では、車線Ｌが延在する方向（図１Ａ、図１Ｂにおける±Ｘ方向）を「車線方向」とも記載し、車線方向に対し水平に直交する方向（図１における±Ｙ方向）を「車線幅方向」とも記載する。また、車線Ｌの車線方向において車両Ａが到来する側（－Ｘ方向側）を車線Ｌの「上流側」とも記載し、車両Ａが退出する側（＋Ｘ方向側）を車線Ｌの「下流側」とも記載する。また、車両Ａが走行する方向（＋Ｘ方向）を基準に、その右側（－Ｙ方向側）を「車線幅方向右側」とも記載し、その左側（＋Ｙ方向側）を「車線幅方向左側」とも記載する。 (Overall structure of toll collection system)
1A and 1B are diagrams showing the overall configuration of a fee collection system according to the first embodiment.
The toll collection system 1 shown in FIG. 1 is installed, for example, at a toll gate (entrance toll gate or exit toll gate) of a toll road. As shown in FIG. 1, the toll collection system 1 is installed in a lane L of a tollgate and an island I laid on the roadside of the lane L.
In the following description, the direction in which the lane L extends (±X direction in FIGS. 1A and 1B) is also referred to as “lane direction”, and the direction that is orthogonal to the lane direction horizontally (±Y direction in FIG. 1). ) Is also described as “lane width direction”. In addition, the side where the vehicle A arrives in the lane direction of the lane L (−X direction side) is also referred to as the “upstream side” of the lane L, and the side where the vehicle A exits (+X direction side) is the “downstream side of the lane L”. ] Is also described. Further, based on the traveling direction of the vehicle A (+X direction), the right side (-Y direction side) is also referred to as "lane width direction right side", and the left side (+Y direction side) is also referred to as "lane width direction left side". Enter.
　車線Ｌの車線幅は、アイランドＩによって車線Ｌ内において車両の入れ替わり（追い抜き等）ができないように調整されている。 Lane width of lane L is adjusted by island I so that vehicles cannot be swapped (passing over, etc.) within lane L.
　図１Ａ、図１Ｂに示すように、料金収受システム１は、車線制御装置１０と、車両検知器１１Ａ、１１Ｂと、料金収受機１２と、発進制御機１３と、車両検知器１４と、リーダ装置１５とを有してなる。 As shown in FIGS. 1A and 1B, a toll collection system 1 includes a lane control device 10, vehicle detectors 11A and 11B, a toll collection device 12, a start control device 13, a vehicle detector 14, and a reader device. 15 and.
　車線制御装置１０（課金装置）は、各種設置機器の全体を制御することで、車線Ｌに進入した車両Ａの搭乗者に対する課金処理を行う。車線制御装置１０が行う具体的な処理については後述する。 The lane control device 10 (billing device) performs a billing process for the passengers of the vehicle A that has entered the lane L by controlling the various installed devices as a whole. Specific processing performed by the lane control device 10 will be described later.
　車両検知器１１Ａ、１１Ｂは、車線Ｌの最も上流側（図１Ａにおける車線方向の位置Ｘ１Ａ、Ｘ１Ｂ）に設けられ、車両Ａの車線Ｌへの進入を検知する。車両検知器１１Ａ、１１Ｂは、主に、車線Ｌ上に存在する車両のキュー管理を行う目的で設置される。
　車両検知器１１Ａ、１１Ｂは、左側のアイランドＩに配置されている投光塔と、右側のアイランドＩに配置されている受光塔と、を有してなる透過型の車両検知器である。車両検知器１１Ａ、１１Ｂは、投光塔の投光素子から投光された光を受光塔の受光素子が受光した否かに応じて、車両Ａの存在を検知する。
　車両検知器１１Ｂは、車両検知器１１Ａよりもわずかに（例えば４０ｃｍ程度）下流側に設けられる。これにより、車線制御装置１０は、車両検知器１１Ａ及び車両検知器１１Ｂの各々から出力される車両検知信号を取得した順番に基づいて、車両の前進・後退を判別することができる。 The vehicle detectors 11A and 11B are provided on the most upstream side of the lane L (positions X1A and X1B in the lane direction in FIG. 1A) and detect the entry of the vehicle A into the lane L. The vehicle detectors 11A and 11B are installed mainly for the purpose of queue management of vehicles existing on the lane L.
The vehicle detectors 11A and 11B are transmissive vehicle detectors having a light projecting tower arranged on the island I on the left side and a light receiving tower arranged on the island I on the right side. The vehicle detectors 11A and 11B detect the presence of the vehicle A depending on whether or not the light receiving element of the light receiving tower receives the light emitted from the light emitting element of the light emitting tower.
The vehicle detector 11B is provided slightly downstream (for example, about 40 cm) from the vehicle detector 11A. As a result, the lane control device 10 can determine whether the vehicle is moving forward or backward based on the order in which the vehicle detection signals output from the vehicle detector 11A and the vehicle detector 11B are acquired.
　料金収受機１２は、車両検知器１１Ａ、１１Ｂの下流側（図１Ａにおける車線方向の位置Ｘ２）に設けられ、到来した車両Ａに搭乗する利用者からの料金の支払いを受け付ける。具体的には、料金収受機１２は、利用者が所持するプリペイド式のＩＣカードのタッチを受け付けて金額の引き去り処理を行う。また、料金収受機１２は、利用者からの現金の投入を受け付けて料金を収受する。 The toll collector 12 is provided on the downstream side of the vehicle detectors 11A and 11B (position X2 in the lane direction in FIG. 1A), and accepts payment of a fee from a user boarding the incoming vehicle A. Specifically, the fee collection machine 12 accepts a touch of a prepaid IC card carried by the user and carries out a withdrawal process. Further, the fee collection machine 12 accepts the input of cash from the user and collects the fee.
　発進制御機１３は、料金収受機１２の更に下流側に設けられ、車線Ｌに進入した車両Ａの発進を制御する。具体的には、発進制御機１３は、通常時においては開閉バーＢを閉状態とし、車両Ａの発進（車線Ｌからの退出）を制限する。また、発進制御機１３は、車両Ａに搭乗する利用者から料金の支払いを適正に受け付けた場合には開閉バーＢを開状態とし、車両Ａの発進を許可する。 The start controller 13 is provided further downstream of the toll collector 12, and controls the start of the vehicle A that has entered the lane L. Specifically, the start controller 13 normally closes the open/close bar B to limit the start of the vehicle A (withdrawal from the lane L). Further, when the start controller 13 properly receives the payment of the charge from the user boarding the vehicle A, the opening/closing bar B is opened and the start of the vehicle A is permitted.
　車両検知器１４は、車線Ｌの最も下流側（図１Ａにおける車線方向の位置Ｘ４）に設けられ、車両Ａの車線Ｌからの退出を検知する。車両検知器１４は、車両検知器１１Ａ、１１Ｂと同様に、車線Ｌ上に存在する車両のキュー管理を行う目的で設置される。また、車両検知器１４による車両検知信号が出力されている間は、発進制御機１３の開閉バーＢが閉状態とならないように制御される。これにより、発進制御機１３の開閉バーＢが退出中の車両と接触することが防止される。 The vehicle detector 14 is provided on the most downstream side of the lane L (position X4 in the lane direction in FIG. 1A) and detects the exit of the vehicle A from the lane L. The vehicle detector 14, like the vehicle detectors 11A and 11B, is installed for the purpose of queue management of vehicles existing on the lane L. Further, while the vehicle detection signal is being output by the vehicle detector 14, the opening/closing bar B of the start controller 13 is controlled so as not to be in the closed state. This prevents the opening/closing bar B of the start controller 13 from coming into contact with the vehicle leaving.
　リーダ装置１５は、無線通信を介して、車両Ａに付されたＲＦＩＤタグ（以下、単に「タグ」とも記載する。）ＴＧから、当該タグＴＧに記録されているタグＩＤを読み取る。タグＩＤとは、タグＴＧに記録されている情報であって、タグＴＧに関連付けられた有料道路の利用者を個々に識別可能な識別情報である。
　図１Ａ、図１Ｂに示すように、リーダ装置１５は、車線Ｌの上方に設置され、その設置位置から下方（車線Ｌの路面）に向けて電波を放射する。これにより、リーダ装置１５は、車線Ｌ上の所定範囲に無線通信可能領域Ｑを形成する。リーダ装置１５は、この無線通信可能領域Ｑの範囲内に存在するタグＴＧと無線通信を行ってタグＩＤを読み取ることができる。しかし、リーダ装置１５が放射した電波が車体や設置機器の表面で反射するなどして、無線通信可能領域Ｑの範囲外に存在するタグ（例えば、車線Ｌの隣の車線を走行する車両に付されたタグ）のタグＩＤを読み取ってしまう場合もある。
　図１Ａ、図１Ｂに示すように、リーダ装置１５は、放射する電波によって車線Ｌ上に形成される無線通信可能領域Ｑが、車両検知器１１Ａ、１１Ｂによる車両検知位置（車線方向の位置Ｘ１Ａ、Ｘ１Ｂ）を含むように設置されている。
　無線通信可能領域Ｑには同時に複数の車両が入らないような大きさに調整されている。例えば、無線通信可能領域Ｑの車線方向の長さは、１．５～２．５メートル程度に調整されるのが好ましい。これにより、ある車両の後方を走行する車両に付されたタグＴＧを先に読み取ってしまうことを防止することができる。 The reader device 15 reads the tag ID recorded in the tag TG from the RFID tag (hereinafter, also simply referred to as “tag”) TG attached to the vehicle A via wireless communication. The tag ID is information recorded in the tag TG and is identification information capable of individually identifying a user of a toll road associated with the tag TG.
As shown in FIGS. 1A and 1B, the reader device 15 is installed above the lane L and emits radio waves downward from the installation position (road surface of the lane L). As a result, the reader device 15 forms the wireless communicable area Q in a predetermined range on the lane L. The reader device 15 can read the tag ID by performing wireless communication with the tag TG existing within the range of the wireless communicable area Q. However, the radio wave radiated by the reader device 15 is reflected on the surface of the vehicle body or the installed device, and therefore, a tag existing outside the range of the wireless communicable area Q (for example, a vehicle traveling in the lane next to the lane L is attached). In some cases, the tag ID of the created tag) is read.
As shown in FIG. 1A and FIG. 1B, in the reader device 15, a wireless communicable area Q formed on the lane L by the radiated radio waves indicates a vehicle detection position by the vehicle detectors 11A and 11B (a lane direction position X1A, X1B) is installed.
The size is adjusted so that a plurality of vehicles cannot enter the wireless communication area Q at the same time. For example, the length of the wireless communicable area Q in the lane direction is preferably adjusted to about 1.5 to 2.5 meters. This makes it possible to prevent the tag TG attached to the vehicle traveling behind a certain vehicle from being read first.
（料金収受システムの機能構成）
　図２は、第１の実施形態に係る料金収受システムの機能構成を示す図である。
　図２に示すように、車線制御装置１０は、ＣＰＵ１００と、通信インタフェース１０１と、メモリ１０２とを有している。 (Functional structure of toll collection system)

　開閉制御部１００５は、課金処理部１００４による課金処理が完了した場合に、発進制御機１３を開制御する。また、開閉制御部１００５は、車両検知器１４による車両検知信号の出力が停止した場合（つまり、車両Ａの車尾が位置Ｘ４を通過した場合）、発進制御機１３を閉制御する。 The transmitting unit 1000 repeatedly transmits a response request signal to the wireless communicable area Q on the lane L via the reader device 15.
The identification information acquisition unit 1001 acquires the tag ID received by the reader device 15 as a response to the response request signal (the tag ID recorded in the tag TG attached to the vehicle A).
The identification information specifying unit 1003 acquires a vehicle detection signal from the vehicle detectors 11A and 11B arranged so as to be able to detect the vehicle existing within the range of the communicable area Q.
The identification information identifying unit 1003 identifies the tag ID acquired within a predetermined period based on the timing of acquiring the vehicle detection signal from the vehicle detectors 11A and 11B among the tag IDs acquired multiple times.
The billing processing unit 1004 performs billing processing based on the tag ID specified by the identification information specifying unit 1003.
The opening/closing control unit 1005 controls the opening control of the start controller 13 when the charging processing by the charging processing unit 1004 is completed. In addition, the opening/closing control unit 1005 closes the start controller 13 when the vehicle detector 14 stops outputting the vehicle detection signal (that is, when the tail of the vehicle A passes through the position X4).

　タグＴＧからの応答信号を受信した場合（ステップＳ０１；ＹＥＳ）、識別情報取得部１００１は、リーダ装置１５を介して、当該応答信号に含まれるタグＩＤと、その取得時刻（タイムスタンプ）を取得識別情報テーブルＴＢに記録する（ステップＳ０２）。タグＴＧからの応答信号を受信していない場合（ステップＳ０１；ＮＯ）、車線制御装置１０は、ステップＳ０２の処理を行うことなく次のステップに進む。 The identification information acquisition unit 1001 of the lane control device 10 determines whether the response signal from the tag TG to the response request signal of step S00 is received via the reader device 15 (step S01).
When the response signal from the tag TG is received (step S01; YES), the identification information acquisition unit 1001 acquires the tag ID included in the response signal and the acquisition time (time stamp) via the reader device 15. The information is recorded in the identification information table TB (step S02). When the response signal from the tag TG is not received (step S01; NO), the lane control device 10 proceeds to the next step without performing the process of step S02.
　次に、車線制御装置１０の車両検知信号取得部１００２は、車両検知器１１Ａ、１１Ｂの各々から、所定の順番（車両検知器１１Ａ、車両検知器１１Ｂの順）で車両検知信号を取得したか否かを判定する（ステップＳ０３）。
　車両検知器１１Ａ、１１Ｂの各々から所定の順番で車両検知信号を受け付けていない場合（ステップＳ０３；ＮＯ）、車線制御装置１０は、ステップＳ００に戻り、上記処理を繰り返し実行する。 Next, whether the vehicle detection signal acquisition unit 1002 of the lane control device 10 has acquired the vehicle detection signals from each of the vehicle detectors 11A and 11B in a predetermined order (the vehicle detector 11A and the vehicle detector 11B in that order). It is determined whether or not (step S03).
When the vehicle detection signals have not been received in a predetermined order from each of the vehicle detectors 11A and 11B (step S03; NO), the lane control device 10 returns to step S00 and repeats the above processing.
　車両検知器１１Ａ、１１Ｂの各々から所定の順番で車両検知信号を取得した場合（ステップＳ０３；ＹＥＳ）、車線制御装置１０の識別情報特定部１００３は、この時点で取得識別情報テーブルＴＢに記録されている複数のタグＩＤのうちの一つを課金対象として特定する処理を行う。具体的には、識別情報特定部１００３は、車両検知器１１Ａ、１１Ｂの各々から所定の順番で車両検知信号を取得したタイミングから、予め定められた所定期間Δｔ前までの間に取得したタグＩＤが存在するか否かを判定する（ステップＳ０４）。
　車両検知器１１Ａ、１１Ｂの各々から所定の順番で車両検知信号を取得したタイミングから所定期間Δｔ前までの間に取得したタグＩＤが存在する場合（ステップＳ０４；ＹＥＳ）、識別情報特定部１００３は、当該所定期間Δｔの中で最も遅く取得したタグＩＤを課金対象として特定する（ステップＳ０５）。 When the vehicle detection signals are acquired in a predetermined order from each of the vehicle detectors 11A and 11B (step S03; YES), the identification information specifying unit 1003 of the lane control device 10 is recorded in the acquisition identification information table TB at this time. One of the plurality of tag IDs that are being charged is specified as a billing target. Specifically, the identification information identifying unit 1003 acquires the tag IDs acquired from the timing when the vehicle detection signals are acquired from each of the vehicle detectors 11A and 11B in a predetermined order and before the predetermined time period Δt. It is determined whether or not exists (step S04).
When there is the tag ID acquired from the timing at which the vehicle detection signals are acquired from each of the vehicle detectors 11A and 11B in the predetermined order and before the predetermined period Δt (step S04; YES), the identification information specifying unit 1003 determines The tag ID acquired latest in the predetermined period Δt is specified as the charging target (step S05).
　車線制御装置１０の課金処理部１００４は、ステップＳ０５で特定されたタグＩＤに基づいて課金処理を行う（ステップＳ０６）。具体的には、課金処理部１００４は、ステップＳ０５で特定されたタグＩＤと課金額とを関連付けて上位装置に送信する。この上位装置には、タグＩＤと利用者に関する個人情報（例えば、口座番号等）とが関連付けられて記録されている。上位装置は、車線制御装置１０からタグＩＤ及び課金額を受信すると、当該タグＩＤに紐づく個人情報を利用して、課金額の引き去り処理を行う。 The charging processing unit 1004 of the lane control device 10 performs charging processing based on the tag ID specified in step S05 (step S06). Specifically, the billing processing unit 1004 associates the tag ID specified in step S05 with the billing amount, and transmits it to the host device. Tag information and personal information about the user (for example, an account number) are associated with each other and recorded in this host device. Upon receiving the tag ID and the charge amount from the lane control device 10, the upper-level device uses the personal information associated with the tag ID to perform the charge amount withdrawal process.
　車両検知器１１Ａ、１１Ｂの各々から所定の順番で車両検知信号を取得したタイミングから所定期間Δｔ前までの間に取得したタグＩＤが存在しない場合（ステップＳ０４；ＮＯ）、車両検知器１１Ａ、１１Ｂを通過した車両ＡのタグＴＧを正しく読み取ることができなかったか、又は、そもそも車両ＡがタグＴＧを付していないことが想定される。そこで、この場合、課金処理部１００４は、車線Ｌに設置された料金収受機１２を通じて課金処理を行う。
　具体的には、課金処理部１００４は、料金収受機１２を有効化する。具体的には、課金処理部１００４は、まず、料金収受機１２での支払いに必要な情報（課金額等）を料金収受機１２に送信する。課金処理部１００４は、料金収受機１２での支払が必要であることを車両Ａの搭乗者等に通知する。例えば、課金処理部１００４は、料金収受機１２のスピーカやディスプレイを通じて、音声によるアナウンスや課金額等を示す案内表示を行う。
　有効化された料金収受機１２は、利用者からＩＣカードのタッチ操作を待ち受ける状態、又は、利用者から現金の投入を待ち受ける状態となる。なお、他の実施形態に係る料金収受機１２は、いつでも一定金額の収受を受け付けられる状態で待機し、車線制御装置１０（課金処理部１００４）からの信号ではなく、利用者からの操作をトリガとして料金収受してもよい。
　続いて、課金処理部１００４は、料金収受機１２を通じた課金処理（ＩＣカードに対する課金額の引き去り処理、投入された現金に対する処理）を行う（ステップＳ０８）。 When there is no tag ID acquired from the timing at which the vehicle detection signals are acquired from each of the vehicle detectors 11A and 11B in a predetermined order and before the predetermined period Δt (step S04; NO), the vehicle detectors 11A and 11B. It is assumed that the tag TG of the vehicle A that has passed through is not correctly read, or that the vehicle A does not have the tag TG in the first place. Therefore, in this case, the charging processing unit 1004 performs the charging processing through the fee collection device 12 installed in the lane L.
Specifically, the billing processing unit 1004 activates the fee collection device 12. Specifically, the billing processing unit 1004 first transmits to the toll collection device 12 the information (billing amount, etc.) necessary for payment at the toll collection device 12. The billing processing unit 1004 notifies the passenger or the like of the vehicle A that payment at the fee collection device 12 is required. For example, the billing processing unit 1004 displays a voice announcement, a guidance display indicating a billing amount, etc. through the speaker and the display of the fee collection device 12.
The activated toll collection machine 12 is in a state of waiting for a touch operation of the IC card by the user, or in a state of waiting for the cash input from the user. It should be noted that the toll collection device 12 according to another embodiment stands by in a state where it can accept collection of a fixed amount of money at any time, and triggers an operation from the user instead of a signal from the lane control device 10 (billing processing unit 1004). You may collect the charges.
Subsequently, the billing processing unit 1004 performs a billing process (a process of deducting the billing amount for the IC card, a process for the inserted cash) through the fee collection device 12 (step S08).
　タグＩＤによる課金処理（ステップＳ０６）、又は、料金収受機１２による課金処理（ステップＳ０８）により課金処理が完了すると、開閉制御部１００５は、発進制御機１３を開制御する（ステップＳ０９）。これにより、車両Ａは、車線Ｌを退出することができる。 When the billing process is completed by the billing process using the tag ID (step S06) or the billing process by the fee collection device 12 (step S08), the opening/closing control unit 1005 controls the start controller 13 to open (step S09). Thereby, the vehicle A can leave the lane L.
　次に、図４、図５を参照しながら、図３の処理フローに基づく車線制御装置１０の具体的な制御例について説明する。
　図３のステップＳ００の処理が繰り返し実行されることで、リーダ装置１５は、応答要求信号を繰り返し発信している、タグＴＧがこの応答要求信号を受信した場合には、直ちに応答信号Ｒを返信する。図４に示すタイミングチャートＤＲは、リーダ装置１５が受信したタグＴＧからの応答信号Ｒの受信状況を時系列で示している。
　なお、上述したように、リーダ装置１５が受信する応答信号Ｒは、リーダ装置１５が形成する無線通信可能領域Ｑ内に存在するタグＴＧから受信したものとは限らない。リーダ装置１５が放射する電波の反射等により、例えば、車線Ｌの隣の車線を走行する車両のタグからの応答信号を受信することも想定される。即ち、タイミングチャートＤＲに示す応答信号Ｒには、車線Ｌに進入した車両以外の車両に付されたタグからの応答信号も含まれている。 Next, a specific control example of the lane control device 10 based on the processing flow of FIG. 3 will be described with reference to FIGS. 4 and 5.
By repeatedly executing the process of step S00 of FIG. 3, the reader device 15 repeatedly transmits the response request signal. When the tag TG receives the response request signal, the reader device 15 immediately returns the response signal R. To do. The timing chart DR shown in FIG. 4 shows the reception status of the response signal R from the tag TG received by the reader device 15 in time series.
Note that, as described above, the response signal R received by the reader device 15 is not necessarily received from the tag TG existing in the wireless communicable area Q formed by the reader device 15. It is also assumed that, for example, a response signal is received from a tag of a vehicle traveling in the lane adjacent to the lane L due to reflection of radio waves radiated by the reader device 15. That is, the response signal R shown in the timing chart DR also includes a response signal from a tag attached to a vehicle other than the vehicle that has entered the lane L.
　車線制御装置１０の識別情報取得部１００１は、タイミングチャートＤＲに示される応答信号Ｒのそれぞれについて、図３のステップＳ０１～ステップＳ０２の処理により、各応答信号Ｒに含まれるタグＩＤと、その取得時刻とを関連付けて取得識別情報テーブルＴＢに記録する（図５参照）。 The identification information acquisition unit 1001 of the lane control device 10 obtains the tag ID included in each response signal R and the acquisition thereof for each of the response signals R shown in the timing chart DR by the processing of steps S01 to S02 in FIG. It is recorded in the acquired identification information table TB in association with the time (see FIG. 5).
　また、図４に示す車両検知信号Ｄ１Ａは車両検知器１１Ａから受信する車両検知信号である。また、図４に示す車両検知信号Ｄ１Ｂは、車両検知器１１Ｂから受信する車両検知信号である。車両Ａが車線Ｌに進入した場合、車両検知信号Ｄ１Ａ→車両検知信号Ｄ１Ｂの順番で“ＯＮ”する。 The vehicle detection signal D1A shown in FIG. 4 is a vehicle detection signal received from the vehicle detector 11A. The vehicle detection signal D1B shown in FIG. 4 is a vehicle detection signal received from the vehicle detector 11B. When the vehicle A enters the lane L, the vehicle detection signal D1A is turned on in the order of the vehicle detection signal D1B.
　図３のステップＳ０３の処理において、車両検知信号取得部１００２は、車両検知信号Ｄ１Ａ→車両検知信号Ｄ１Ｂの順番で“ＯＮ”したか否かを判定する。車両検知信号Ｄ１Ａが時刻ｔ１Ａで“ＯＮ”し、続いて、車両検知信号Ｄ１Ｂの順番で“ＯＮ”した場合、車両検知信号取得部１００２は、そのときの時刻ｔ１Ｂを取得する。
　この場合、車線制御装置１０の識別情報特定部１００３は、時刻ｔ１Ｂから所定期間Δｔだけ遡った時刻ｔａ（＝ｔ１Ｂ－Δｔ）を算出する。そして、識別情報特定部１００３は、図５の取得識別情報テーブルＴＢを参照して、各タグＩＤについて、その取得時刻が時刻ｔａ～時刻ｔ１Ｂの間に含まれているか否かを判定する。識別情報特定部１００３は、取得時刻が時刻ｔａ～時刻ｔ１Ｂの間に含まれているタグＩＤを抽出する。取得時刻が時刻ｔａ～時刻ｔ１Ｂの間に含まれているタグＩＤが複数存在する場合は、識別情報特定部１００３は、その中から最も遅く取得したタグＩＤ（図５に示す例では、“ＩＤ３”）を特定する。そうした場合、図３のステップＳ０６の処理において、課金処理部１００４は、ステップＳ０５で特定されたタグＩＤ（“ＩＤ３”）と課金額とを関連付けて上位装置に送信する。 In the process of step S03 of FIG. 3, the vehicle detection signal acquisition unit 1002 determines whether the vehicle detection signal D1A is turned on in the order of the vehicle detection signal D1B. When the vehicle detection signal D1A turns “ON” at time t1A and subsequently turns “ON” in the order of the vehicle detection signal D1B, the vehicle detection signal acquisition unit 1002 acquires the time t1B at that time.
In this case, the identification information identifying unit 1003 of the lane control device 10 calculates the time ta (=t1B-Δt) which is traced back from the time t1B by the predetermined period Δt. Then, the identification information identifying unit 1003 refers to the acquisition identification information table TB of FIG. 5 and determines whether the acquisition time of each tag ID is included between the time ta and the time t1B. The identification information specifying unit 1003 extracts the tag ID whose acquisition time is included between the time ta and the time t1B. When there are a plurality of tag IDs whose acquisition time is included between the time ta and the time t1B, the identification information specifying unit 1003 acquires the latest tag ID from the tag IDs (“ID3 in the example shown in FIG. 5”). )) is specified. In such a case, in the process of step S06 of FIG. 3, the billing processing unit 1004 transmits the tag ID (“ID3”) specified in step S05 and the billing amount in association with each other to the host device.
　なお、取得識別情報テーブルＴＢにおいて、時刻ｔａ～時刻ｔ１Ｂの間に取得されたタグＩＤが存在しなかった場合、識別情報特定部１００３は、課金対象とするタグＩＤを特定することはできない（図３のステップＳ０４；ＮＯ）。この場合、課金処理部１００４は、料金収受機１２を有効化して、当該料金収受機１２を通じた課金処理を行う（図３のステップＳ０７～ステップＳ０８参照）。 In the acquired identification information table TB, when the tag ID acquired between time ta and time t1B does not exist, the identification information specifying unit 1003 cannot specify the tag ID to be charged (see FIG. 3 step S04; NO). In this case, the billing processing unit 1004 activates the toll collection machine 12 and performs the billing process through the toll collection machine 12 (see steps S07 to S08 in FIG. 3).
（作用・効果）
　以上の通り、第１の実施形態に係る車線制御装置１０（課金装置）は、リーダ装置１５を介して車線Ｌ上の無線通信可能領域Ｑに応答要求信号を繰り返し発信する発信部１０００と、リーダ装置１５が応答要求信号に対する応答として受信した情報であって、車両Ａに付されたタグＴＧ（情報記録媒体）に記録されたタグＩＤ（識別情報）を取得する識別情報取得部１００１と、通信可能領域Ｑ内に存在する車両Ａを検知可能に配置された車両検知器１１Ａ、１１Ｂから車両検知信号を取得する車両検知信号取得部１００２と、複数回取得したタグＩＤのうち車両検知信号を取得したタイミング（図４の時刻ｔ１Ｂ）を基準とする所定期間内（図４の時刻ｔａ～時刻ｔ１Ｂの間）に取得したタグＩＤを特定する識別情報特定部１００３と、識別情報特定部１００３によって特定されたタグＩＤに基づいて課金処理を行う課金処理部１００４と、を備える。
　このようにすることで、複数回取得されたタグＩＤのうち、課金対象とする車両Ａが無線通信可能領域Ｑ内に確実に存在するタイミングとほぼ同時刻に取得したタグＩＤを、その車両Ａに付されたタグＴＧのタグＩＤであると推定して課金処理を行うことができる。ここで、リーダ装置１５は、異なる位置に複数のタグが存在した場合に、その中から最も強い応答信号に含まれるタグＩＤ（即ち、リーダ装置１５に最も近いタグに記録されたタグＩＤ）を読み取りやすいという特性を有する。そのため、車両検知信号を取得したタイミングとほぼ同時刻に取得したタグＩＤは、その時点で無線通信可能領域Ｑ内に存在する車両Ａ（即ち、課金対象とする車両Ａ）に付されたタグＴＧに記録されたタグＩＤである可能性が高い。したがって、課金対象とする車両Ａが無線通信可能領域Ｑ内に確実に存在するタイミングとほぼ同時刻に取得したタグＩＤを、その車両Ａに付されたタグＴＧのタグＩＤであると推定することで、課金対象とする車両Ａ（車線Ｌの無線通信可能領域Ｑ内に存在する車両Ａ）から正しく課金できる可能性を高めることができる。
　以上より、第１の実施形態に係る車線制御装置１０によれば、誤課金が発生しにくい料金収受システムを提供することができる。 (Action/effect)
As described above, the lane control device 10 (billing device) according to the first embodiment includes the transmitting unit 1000 that repeatedly transmits the response request signal to the wireless communicable area Q on the lane L via the reader device 15, and the reader. Communication with the identification information acquisition unit 1001 that acquires the tag ID (identification information) recorded in the tag TG (information recording medium) attached to the vehicle A, which is information received by the device 15 in response to the response request signal. A vehicle detection signal acquisition unit 1002 that acquires a vehicle detection signal from vehicle detectors 11A and 11B that are arranged to detect the vehicle A existing in the possible area Q, and a vehicle detection signal that is acquired from a plurality of tag IDs acquired multiple times. The identification information identifying unit 1003 that identifies the tag ID acquired within a predetermined period (between time ta and time t1B in FIG. 4) based on the timing (time t1B in FIG. 4) identified by the identification information identifying unit 1003. And a billing processing unit 1004 that performs billing processing based on the tag ID thus obtained.
By doing so, among the tag IDs acquired a plurality of times, the tag ID acquired at substantially the same time as the timing when the vehicle A to be charged certainly exists in the wireless communicable area Q is used as the vehicle ID. It is possible to perform the charging process by presuming that the tag ID is the tag ID of the tag TG attached to. Here, when there are a plurality of tags at different positions, the reader device 15 gives the tag ID included in the strongest response signal among them (that is, the tag ID recorded in the tag closest to the reader device 15). It is easy to read. Therefore, the tag ID acquired at almost the same time as the time when the vehicle detection signal is acquired is the tag TG attached to the vehicle A (that is, the vehicle A to be charged) existing in the wireless communicable area Q at that time. There is a high possibility that the tag ID is recorded in. Therefore, it is assumed that the tag ID acquired at substantially the same time when the vehicle A to be charged exists in the wireless communicable area Q is the tag ID of the tag TG attached to the vehicle A. Thus, it is possible to increase the possibility that the vehicle A to be charged (the vehicle A existing in the wireless communicable area Q of the lane L) can be charged correctly.
As described above, according to the lane control device 10 according to the first embodiment, it is possible to provide a toll collection system in which incorrect charges are less likely to occur.
　また、第１の実施形態に係る車線制御装置１０（課金処理部１００４）は、識別情報特定部１００３によってタグＩＤが特定されなかった場合に、車線Ｌに設置された料金収受機１２を通じて課金処理を行う（図３のステップＳ０４；ＮＯ、ステップＳ０７、ステップＳ０８参照）。
　このようにすることで、タグを付していない車両やタグに不具合がある車両に対しては、料金収受機１２を介して課金することができる。 Further, the lane control device 10 (billing processing unit 1004) according to the first embodiment performs the billing process through the fee collection device 12 installed in the lane L when the tag ID is not identified by the identification information identifying unit 1003. Is performed (step S04 of FIG. 3; NO, see step S07, step S08).
By doing so, it is possible to charge the vehicle not tagged or the vehicle having a defective tag through the fee collection device 12.
　また、第１の実施形態に係る車両検知信号取得部１００２は、通信可能領域Ｑ内に存在する車両を検知可能に配置された二つの車両検知器１１Ａ、１１Ｂの各々から車両検知信号Ｄ１Ａ、Ｄ１Ｂを取得する。そして、識別情報特定部１００３は、当該二つの車両検知器１１Ａ、１１Ｂの各々から予め定められた順序で車両検知信号を取得した場合に、タグＩＤを特定する。
　このように、二つの車両検知信号の順番を判定条件とすることで、車両が正しく進入した場合のみ課金処理を行うことができる。 In addition, the vehicle detection signal acquisition unit 1002 according to the first embodiment detects vehicle detection signals D1A and D1B from each of the two vehicle detectors 11A and 11B that are arranged to detect vehicles existing in the communicable area Q. To get Then, the identification information identifying unit 1003 identifies the tag ID when the vehicle detection signals are acquired from each of the two vehicle detectors 11A and 11B in a predetermined order.
In this way, by using the order of the two vehicle detection signals as the determination condition, it is possible to perform the charging process only when the vehicle correctly enters.
　また、第１の実施形態に係る開閉制御部１００５は、課金処理が完了した場合に、発進制御機１３を開制御する。
　このようにすることで、リーダ装置１５を介して読み取られたタグＩＤによる課金処理が完了した場合に、直ちに発進制御機１３を開制御させ、車両Ａを車線Ｌから退出させることができる。 Further, the opening/closing control unit 1005 according to the first embodiment controls the opening control of the start controller 13 when the billing process is completed.
By doing so, when the billing process based on the tag ID read via the reader device 15 is completed, the start controller 13 can be immediately opened and the vehicle A can be exited from the lane L.
（第１の実施形態に係る料金収受システムの製造方法）
　図１、図２を参照しながら、第１の実施形態に係る料金収受システム１の製造方法について説明する。 (Method for manufacturing the fee collection system according to the first embodiment)
A method of manufacturing the fee collection system 1 according to the first embodiment will be described with reference to FIGS. 1 and 2.
　第１の実施形態に係る料金収受システム１は、既設の料金収受システムに対し、リーダ装置１５等を追設することで製造してもよい。ここで、既設の料金収受システムは、車線制御装置１０、車両検知器１１Ａ、１１Ｂ、料金収受機１２、発進制御機１３及び車両検知器１４を備えている。ただし、この段階では、車線制御装置１０は、料金収受機１２を通じた課金処理の機能を有するのみで、リーダ装置１５を用いた課金処理に係る機能を有していない。 The fee collection system 1 according to the first embodiment may be manufactured by adding the reader device 15 and the like to the existing fee collection system. Here, the existing toll collection system includes a lane control device 10, vehicle detectors 11A and 11B, a toll collector 12, a start controller 13 and a vehicle detector 14. However, at this stage, the lane control device 10 only has the function of the charging process through the toll collection device 12, and does not have the function of the charging process using the reader device 15.
　料金収受システム１を製造するにあたり、作業者は、既設の料金収受システムに対し、車線Ｌ上に形成される無線通信可能領域Ｑが、車両検知器１１Ａ、１１Ｂの検知位置（位置Ｘ１、Ｘ２）を含むように、リーダ装置１５を追設する。
　次に、作業者は、車線制御装置１０に対し、発信部１０００、識別情報取得部１００１、車両検知信号取得部１００２及び識別情報特定部１００３としての機能を追加する。 When manufacturing the toll collection system 1, the worker has a wireless communication area Q formed on the lane L in the existing toll collection system, where the wireless detectors 11A and 11B detect positions (positions X1 and X2). The reader device 15 is additionally provided so as to include.
Next, the worker adds the functions of the transmission unit 1000, the identification information acquisition unit 1001, the vehicle detection signal acquisition unit 1002, and the identification information identification unit 1003 to the lane control device 10.
　このようにすることで、第１の実施形態に係る料金収受システム１を安価かつ簡便に製造することができる。 By doing so, the fee collection system 1 according to the first embodiment can be manufactured inexpensively and easily.
（変形例）
　以上、第１の実施形態に係る料金収受システム１及び車線制御装置１０について詳細に説明したが、料金収受システム１及び車線制御装置１０の具体的な態様は、上述のものに限定されることはなく、要旨を逸脱しない範囲内において種々の設計変更等を加えることは可能である。 (Modification)
Although the toll collection system 1 and the lane control device 10 according to the first embodiment have been described above in detail, the specific aspects of the toll collection system 1 and the lane control device 10 are not limited to those described above. It is possible to add various design changes and the like without departing from the gist of the invention.
　例えば、第１の実施形態に係る識別情報特定部１００３は、車両検知信号を取得した時刻ｔ１Ｂから所定期間Δｔだけ遡った時刻ｔａまでの間に取得したタグＩＤを特定するものとして説明したが、他の実施形態においてはこの態様に限定されない。
　例えば、他の実施形態に係る識別情報特定部１００３は、時刻ｔ１Ｂから所定期間Δｔだけ経過した時刻（ｔ１Ｂ＋Δｔ）までの間に取得したタグＩＤを特定してもよい。また、他の実施形態に係る識別情報特定部１００３は、時刻ｔ１Ｂを含む所定幅（Δｔ）の期間（時刻ｔ１Ｂ－Δｔ１～時刻ｔ１Ｂ＋Δｔ２、Δｔ１＋Δｔ２＝Δｔ）に取得したタグＩＤを特定してもよい。 For example, the identification information specifying unit 1003 according to the first embodiment has been described as specifying the tag ID acquired between the time t1B when the vehicle detection signal is acquired and the time ta which is traced back by a predetermined period Δt. Other embodiments are not limited to this aspect.
For example, the identification information identifying unit 1003 according to another embodiment may identify the tag ID acquired from the time t1B to the time (t1B+Δt) after the elapse of the predetermined period Δt. Further, the identification information identifying unit 1003 according to another embodiment may identify the tag ID acquired during a period of a predetermined width (Δt) including the time t1B (time t1B-Δt1 to time t1B+Δt2, Δt1+Δt2=Δt). ..
　また、第１の実施形態に係る識別情報特定部１００３は、所定期間Δｔの間に複数のタグＩＤが取得されていた場合には、その中から最も遅く取得された一つのタグＩＤを特定するものとして説明したが、他の実施形態においてはこの態様に限定されない。即ち、識別情報特定部１００３は、所定期間Δｔの間に取得されていた複数のタグＩＤの中からいずれか一つのタグＩＤを特定する機能を有していれば、その手法は如何なる態様であってもかまわない。
　例えば、他の実施形態に係る識別情報特定部１００３は、所定期間Δｔの間に複数回タグＩＤが取得されていた場合には、その中から、同一のタグＩＤとして複数回取得されているタグＩＤを一つ特定してもよい。より具体的な一例としては、識別情報特定部１００３は、所定期間Δｔの間で取得されたタグＩＤのうち、同一のタグＩＤとして最も多く取得されている一つのタグＩＤを特定する。
　このようにすることで、タグＩＤが複数回取得されたことを条件として、当該車線を走行していた車両のタグＩＤとみなすので、誤課金が発生する可能性を一層低減することができる。 Further, when a plurality of tag IDs are acquired during the predetermined period Δt, the identification information specifying unit 1003 according to the first embodiment specifies the one tag ID acquired latest from them. However, the present invention is not limited to this aspect in other embodiments. That is, as long as the identification information specifying unit 1003 has a function of specifying any one tag ID from the plurality of tag IDs acquired during the predetermined period Δt, the method is in any form. It doesn't matter.
For example, when the tag ID has been acquired multiple times within the predetermined period Δt, the identification information identifying unit 1003 according to another embodiment selects from among them the tag that has been acquired multiple times as the same tag ID. You may specify one ID. As a more specific example, the identification information identifying unit 1003 identifies one tag ID that is acquired most as the same tag ID among the tag IDs acquired during the predetermined period Δt.
By doing so, the tag ID is regarded as the tag ID of the vehicle traveling in the lane on condition that the tag ID has been acquired a plurality of times, and thus the possibility of incorrect charging can be further reduced.
