Description

【００３４】
自動改札機の乗客センサが感知を始めてから時間ｔ₁だけ、探して発見した定期券を、その乗客が所有している定期券とみなす。表１の例では、乗客１からは２枚、乗客２からは１枚、乗客３からは３枚の定期券を検知したことを示している。乗客数、通し番号は例えばこの例のように、自動改札機が稼働してから、初期値１から１ずつインクリメントすればよい。ＩＤ番号は定期券独自に記憶してあるＩＤ番号である。図１で述べたように、定期券と自動改札機はこのＩＤ番号をキーにして、情報の読み書きを実行する。情報の読み書きとは、図１のステップ１０３、１０４、１０５等の処理である。読み書きの処理が終われば、’処理済’のフラグを０から１に変化させる。ここでは、６番の定期券を検知したものの、まだ読み書きの処理が済んでいないことを示している。各乗客が有効な切符を入力したか否かを’切符有’というフラグで示す。有効な切符の投入が有ればその区間を、なければ’０’を記述する。乗車区間は、その定期券で乗れる範囲を示す。有効期間は、その定期券が使用できる期間であるが、具体例の説明は本発明では省略する。
【００３５】
ラッシュ時以外なら、時間ｔ₁の間に１人の乗客の所有する定期券を正しく読むことは比較的容易である。問題は、ラッシュ時のように微小時間間隔に自動改札機に２人の乗客が現われた時である。例えば、乗客１の定期券を読んでいる時間ｔ₁の間に、乗客２の定期券も読んでしまうことも考えられる。こういう場合は、正規な乗車をしている乗客に不正乗車の疑いをかけることはできないので、以下のような処理を行う。
【００３６】
図１の処理のようにｎ番目の乗客のチェック（以下乗客ｎの処理）を行う時、その乗客が所有している定期券は、乗客（ｎ−１）が自動改札機に接近してから検知した定期券と、と乗客ｎが自動改札機に接近してから検知した定期券の両方を考慮する。表１の例では、乗客２の処理を行っている時は、「乗客２は、定期券通し番号１から３までを所有している」と考える（以下では、’定期券通し番号ｎ’を’定期券ｎ’と表現する）。もし、乗客２が定期券３と乗車区間Ａ−Ｃの切符だけなら、それらの区間は連続していないので、不正乗車する疑いが有るので、定期券３にＡ駅から乗車したことを、書き込む。しかし、もし定期券２が乗客２のものならば、正常な乗車であるので、定期券２に「Ａ駅から乗車」と書き込んではいけない。このように、ラッシュ時には、１人手前の乗客の定期券の情報も読み、図１の処理を行う。乗客１の処理を行った時に、定期券２に「Ａ駅から乗車」と書き込んでも、乗客２の処理を行った時に正常な乗車であることが分かれば、それをクリアする、またはＣ駅からＤ駅までのいずれかの駅名を書き込む。従って、ラッシュ時には処理済フラグを２ビット設ける。例えば乗客（ｎ−１）の処理済フラグの１ビット目は乗客（ｎ−１）を処理する時に用いて、２ビット目は乗客ｎを処理する時に用いる。
【００３７】
同様にして、乗客（ｎ＋１）の処理を行う時は、乗客ｎが自動改札機に接近してから検知した定期券と、乗客（ｎ＋１）が自動改札機に接近してから検知した定期券を考慮し、処理を行う。このようにして正常な乗車をしている乗客に迷惑がかからないようにする。ラッシュ時のモードか通常のモードかは、係員が自動改札機に接続してあるコントローラからスイッチを切り替えたり、タイマーによってソフトウェアで自動的に切り替えても良い。
【００３８】
図３に乗客がＡ駅で下車する時の、自動改札機と定期券の処理の流れを示す。
【００３９】
ステップ３０１
自動改札機は自分が持つ乗客センサで、乗客が来たのを感知すれば、定期券に’ＩＤ番号を送れ’という命令を発信する。
【００４０】
ステップ３０２
ステップ３０１で自動改札機から定期券に発した命令に対して、もしその乗客が定期券を保有していれば、自動改札機に定期券固有のＩＤ番号を発信しているので、それを自動改札機が受信したかどうかを判定する。受信していればステップ３０３へ、そうでなければステップ３０１ヘ進む。
【００４１】
ステップ３０３
この乗客は、定期券を保有しているので、自動改札機から定期券に、ステップ３０２で受信した「ＩＤ番号」と「乗車区間を報告せよ」という命令を発信する。それを受けた定期券は、上記「ＩＤ番号」が自分の番号であることを確認した後、自分の「ＩＤ番号」と「定期券所定の乗車区間」を自動改札機に発信する。自動改札機はそれらを読み取り、「ＩＤ番号」と「乗車区間」を対応付けて、記憶する。
【００４２】
ステップ３０４
ステップ３０３と同様にして、自動改札機は定期券の有効期間を読み取る。
【００４３】
ステップ３０５
乗車駅、乗車日時に矛盾はないか？をチェックする。例えば、この定期券の所定の乗車区間が、Ａ駅からＢ駅までであっても、定期券の乗車駅名がこの区間でなければ、矛盾が有る、と判断する。また、乗車日時が現在時刻よりも所定の時間以上も以前であれば、乗車日時に矛盾がある、と判断し、表２のＯＫｏｒＮＧフラグにＮＧを書き込み、矛盾がなければＯＫを書き込む。
【００４４】
ステップ３０６
乗客センサが感知し始めてから、ｔ₁秒経過したか否か判断する。もうすでに、ｔ₁秒経過していたらステップ３０７へ進み、まだｔ₁秒経過していなければ、ステップ３０１へ戻り、他の定期券を探す。
【００４５】
ステップ３０７
自動改札機に切符が入力されていれば、ステップ３０８へ進む。そうでなければ、ステップ３０９へ進む。
【００４６】
ステップ３０８
入力された切符は下車可能な切符かどうか判定する。下車可能であればステップ３１０へ、そうでなければステップ３１４へ進む。
【００４７】
ステップ３０９
自動改札機が検知した定期券の中で、下車可能な定期券があるかどうかを、表２のＯＫｏｒＮＧフラグを参照して、判定する。下車可能な定期券があればステップ３１２へ、なければステップ３１４へ進む。自動改札機が定期券を１枚も検知できなかった場合は、ステップ３１４に進むことは言うまでもない。
【００４８】
ステップ３１０
自動改札機が検知した定期券があるか否か判定する。この乗客が定期券を所有していればステップ３１１へ、所有していなければステップ３１３へ進む。
【００４９】
ステップ３１１
切符だけによる正常な乗車なので、もしその乗客が定期券を保有していれば、すべての定期券の乗車に関する情報をクリアする。
【００５０】
ステップ３１２
正常な乗車なので、その乗客が保有しているすべての定期券の乗車に関する情報をクリアする。
【００５１】
ステップ３１３
この乗客は、下車可能な切符または、定期券を保有しているので、自動改札機のゲートを開けて、下車を認める。
【００５２】
ステップ３１４
下車できる切符も定期券もないので、自動改札機のゲートを閉め、音を発したりして、その乗客が下車できないようにする。
【００５３】
ステップ３１１、ステップ３１２で、乗車に関する情報をクリアする、と述べたが、その必要性を説明する。図２で、「切符と定期券の乗車区間が連続しない場合、定期券の乗車駅名にＡ駅と書き込む」と述べた。Ｄ駅からＣ駅まで有効な切符と、Ｂ駅からＡ駅まで有効な定期券を使って、Ｄ駅から切符で乗車し、Ａ駅で定期券を使って下車すると、不正乗車となるが、この乗客が切符を使ってＣ駅で下車する時は、正常な乗車である。この場合は、乗車時に書き込んだ乗車駅名＝Ｄ駅、をクリアする必要が有る。ステップ３１１がこれにあたる。また、複数枚の定期券で有効な乗車をした場合は、下車時にすべての定期券の乗車に関する情報をクリアする。ステップ３１２がこれにあたる。
【００５４】
表２に、下車の場合、自動改札機が乗客の投入した切符、乗客が所有している定期券の情報を、読み取った例を示す。
【００５５】
【表２】

【００５６】
乗車の時と同様、自動改札機が乗客センサで乗客を感知してから時間ｔ₁の間、検知した定期券をその乗客が所有している定期券と考える。
【００５７】
乗客１は３枚、乗客２から乗客４は２枚の定期券を所有している。乗客１はＤ駅から乗車したので、定期券１、２、３には乗車駅名がＤ駅、と乗車の時に書き込まれている。乗客１は定期券１が有るので、下車可能である、とステップ３０５は判定し、ＯＫｏｒＮＧの欄に’ＯＫ’と記述する。その他の定期券に対しては、’ＮＧ’と記述する。また、ステップ３１２で定期券１、２、３の乗車に関する情報をクリアする。
【００５８】
乗客２は有効な切符を投入したので、切符有フラグに１が立っている。定期券４、５は下車不可能であるが、（Ａ−Ｚ）間で有効な切符を投入したので、下車可能とする。ただし下車する前に、ステップ３１１で定期券４、５の乗車に関する情報をクリアする。
【００５９】
乗客３はＣ駅から（Ｃ−Ｂ）間で有効な切符で乗車した。その切符と定期券７は区間が連続しているので、ステップ１１６で乗車駅名をＢ駅と記述した。従って、定期券７で下車可能である、と判定する。
【００６０】
乗客４はＤ駅から（Ｄ−Ｃ）間で有効な切符で乗車したので、定期券８、９には乗車駅＝Ｄ駅と記録してある。しかし下車時はその切符を投入せず、定期券８で下車しようとしたいわゆるキセル乗車である。定期券８で下車しようとしても、乗車駅名＝Ｄ駅と記録してあるので、下車は認めない。
【００６１】
ＯＵＴｏｒＩＮとあるのは、ＯＵＴがもう自動改札機の外へ出た。ＩＮがまだ自動改札機の中に滞留している、を意味する。表２では、本発明とは直接関係ないので、有効期間と乗車日時の具体例は省略する。
【００６２】
このように本実施例によるとキセル乗車を防止するだけでなく、２枚以上の定期券を使ったり、１枚の切符と１枚または複数の定期券を使って正常な乗車をした乗客を区別することができる。従って、正常な乗車をした乗客には迷惑をかけることなく、不正乗車した乗客だけを発見することができる。
【００６３】
ラッシュ時は、乗車の場合に述べたように乗客（ｎ＋１）の処理をする場合は、乗客ｎと乗客（ｎ＋１）が所有していると考えられる定期券すべてを対象にして下車可能であるか否かを判定する。表２の例では、もし定期券７が乗客４の物であれば、乗客４の下車をＯＫにする。
【００６４】
自動改札機の導入が全駅一斉でなく、段階的に行われるならば、次のことにも留意が必要である。
【００６５】
（１）乗車駅に自動改札機がなく、下車駅にある場合
乗車駅名、乗車日時が書き込まれていないので、いつ、どこから乗車したのか不明であるが、不正乗車の証拠がないので、下車を認める。
【００６６】
（２）乗車駅に自動改札機があり、下車駅にない場合
乗車駅名、乗車日時がクリアされずに、定期券に残る。この後、上記（１）の場合になると、下車時の情報では、「数日前に乗車した」ということになる。従って、ステップ３０５で乗車日時に矛盾がないか否かチェックする、と述べたが、「所定の日数が経過していれば有効」等の判断をしなければならない。
【００６７】
また、現在は２つの鉄道会社が、乗換え駅で改札口を通らずに、乗換え可能を認めていることがある。ある乗客が（Ａ−Ｂ）間で有効な定期券１と（Ｂ−Ｃ）間で有効な定期券２を持って、Ａ駅からＣ駅まで乗車する場合を考える。Ｂ駅で改札口を通らずに乗り換えれば、定期券１の乗車に関する情報をクリアできないし、定期券２に乗車に関する情報を書き込むことができない。このような場合は、Ｂ駅の連絡通路に定期券専用の非接触ＩＣカードのリーダライタを設置し、乗客がポケットに定期券を入れたまま通行できるようにして、定期券を読み書きすればよい。これは、ステップ１０１からステップ１０５、及びステップ３０１からステップ３０５の手順で実現可能である。この方法であれば、乗客に「自動改札機を通らなければならない」という煩わしさを取り除くことができ、正しい乗車に関する情報の読み書きが可能になる。
【００６８】
次に、自動改札機を通らずに、有人改札口から乗車する乗客の対策を考える。有人改札口にも非接触ＩＣカードのリーダライタを設置し、定期券を読み書きする。そして駅員の側には切符リーダを設置し、切符を駅員に見せて乗車する乗客からは、その切符を受け取り、設置した切符リーダで切符の情報を読めば良い。切符の情報を読むのと並行して、非接触ＩＣカードのリーダライタでその乗客が定期券を持っているか否かを調べる。これは、図１、図２の手順で実現可能である。切符の搬送のみを自動改札機の代わりに駅員が代行するだけで、後は図１、図２と同じ処理を実行する。有人改札口で定期券を見せて下車する乗客に対しては、非接触ＩＣカードのリーダライタで、その定期券の乗車に関する情報等を読み、正常な乗車か否かを調べることができる。有人改札口に切符を出して下車する乗客がいれば、駅員がそれを切符リーダに入力し、非接触ＩＣカードのリーダライタはこの乗客が定期券を所有しているか否かを探す。定期券を所有していれば、そこに書き込まれている乗車に関する情報をクリアする。これは、図３、図４の手順で実現可能である。この方法で、有人改札口を通って不正乗車を行う乗客を発見することができる。
【００６９】
第２の実施例として、乗車、下車時には乗客に、定期券を自動改札機の読み取り部に近付けてもらう、という方法を述べる。この方法では、乗車時は乗客が隠し持っている定期券を探すため、第１の実施例と同様に、自動改札機の発信部は強い電波を発する。逆に下車時は乗客が差し出した定期券で、正常な乗車か否か判定すれば良いので、自動改札機の発信部は乗車時よりも弱い電波で、定期券を検知することができる。本実施例によると、乗客が自動改札機に定期券を近付けるので、自動改札機は乗客の到着順に正しく定期券を読める、という効果がある。デメリットとして、下車時は弱い電波で、読み書きするので、ポケットに所有している定期券の乗車に関する情報をクリアできない可能性が有るが、今度その定期券で乗車する時に、強い電波で乗車に関する情報を書き込めば良い。
【００７０】
「非接触ＩＣカードをポケットに入れたままで、乗車、下車でき、その情報をホストコンピュータに転送して、後日乗客の口座から運賃を引き落す」というシステムが発表されている。しかし、１人の乗客が複数枚のＩＣカードを所有している場合の対策は、述べられていない。従って、乗客１が何らかの都合で自分のＩＣカードと、乗客２のＩＣカードの２枚を持って乗車すると、乗車していない乗客２からも運賃を徴収してしまう、という問題があった。第３の実施例では、この場合の対策を述べる。乗車時、図１の処理で１人の乗客が複数枚のＩＣカードを所有している、と自動改札機が判断すれば、１枚のＩＣカードに対してのみ、乗車に関する情報を書き込む。図１では、’定期券’と記述してあるが第３の実施例では、’定期券’を’ＩＣカード’に置き換えて考えることは言うまでもない。下車時の処理は２通り考えられる。１つ目は、乗車と同様の処理で１人の乗客が複数枚のＩＣカードを所有しているのを検知すると、乗車に関する情報が書き込んであるＩＣカード（１枚とは限らない）すべてに下車を記録して、ホストコンピュータに報告する、という方法である。２つ目は、乗車に関する情報が書き込んであるＩＣカードの中で、１枚にだけ下車を記録して、ホストコンピュータに報告する、という方法である。本実施例によると、乗車していない乗客から運賃を徴収する、という間違った運営を防止することができる。
【００７１】
【発明の効果】
本発明によれば、１枚だけでなく、複数枚の定期券を有している乗客に対しても、不正乗車を防止できる効果がある。

[Industrial application fields]
The present invention relates to a method for preventing unauthorized boarding of a railway engine or the like.
[0002]
[Prior art]
It is considered to apply it to tickets, commuter passes, etc. using a non-contact readable / writable IC card. However, a method for preventing illegal boarding by combining this card with a ticket is not discussed.
[0003]
On the other hand, the inventors filed an illegal boarding prevention method combining one ticket and one contactless IC card commuter pass in Japanese Patent Application No. 5-79338.
[0004]
Japanese Patent Publication No. 61-58872 describes a method for preventing unauthorized passengers who get on one commuter pass and get off on another commuter pass.
[0005]
[Problems to be solved by the invention]
In Japanese Patent Application No. Hei 5-79338, when one passenger has a plurality of commuter passes and gets on and off the automatic ticket gate, it does not consider reading and writing information on all commuter passes.
[0006]
In JP-B-61-58872, passengers who possessed two regular commuter passes (A-B commuter pass and B-C commuter pass) do not pass through the automatic ticket checker at station B. When changing at the mouth, there was a problem that when getting off at station C, it was treated as an illegal ride even though it was a normal ride.
[0007]
[Means for Solving the Problems ]
[0008]
When a passenger gets on a ticket, the automatic ticket gate looks for and reads a ticket and an IC card commuter pass that may be owned by the passenger for a certain period of time, and determines whether the boarding section is continuous or not For non-continuous IC card commuter passes, information on boarding such as the boarding station name is written in the IC card commuter pass. When the passenger gets off with the IC card commuter pass, the information on boarding the IC card commuter pass and the boarding section are compared, and a means for determining whether or not the passenger has boarded from the predetermined boarding section is provided. Discover unauthorized passengers who board from outside the boarding section.
[0009]
[Action]
The automatic ticket gate installed at the ticket gate checks the range that can be boarded with a ticket by means of reading a magnetized ticket. In addition, since there is a means to detect when the passenger approaches, the IC card can be detected periodically by means of issuing a signal to the IC card commuter pass owned by the passenger for a predetermined time from the time the passenger is detected. Find out if you have a ticket. If the signal from the IC card commuter pass is received, it can be understood that the passenger owns the IC card commuter pass. If a plurality of IC card commuter passes are detected, the boarding sections of all the IC card commuter passes are checked by means for reading the information of the IC card commuter pass.
[0010]
When the passenger gets on the ticket, the automatic ticket gate reads the ticket and the IC card commuter pass and determines whether the boarding section is continuous or not. The information on boarding such as the boarding station name is written by means for writing information on boarding on the IC card commuter pass.
[0011]
When the passenger gets off with the IC card commuter pass, the information on the boarding and the boarding section of the IC card commuter pass are compared, and a means for determining whether the passenger has boarded from the predetermined boarding section Discover unauthorized passengers boarding from outside.
[0012]
【Example】
Prior to the description of the examples, terms will be defined. Getting on and getting off originally means getting on the train or getting off the train, but in this specification, entering the station from the automatic ticket gate is 'riding', outside the station from the automatic ticket gate Getting out is called 'getting off'.
[0013]
In addition to tickets and commuter passes, there are prepaid cards and postpaid credit cards, and in the case of getting off, there is also a checkout statement that proves that the insufficient fee has been paid at the station. In the following embodiment, when you get on a 'ticket', it includes a prepaid card and a credit card in addition to a ticket, and when you get off at a 'ticket', it includes not only the card but also a checkout statement. . Furthermore, the commuter pass uses a non-contact readable / writable IC card. The non-contact IC card is described in, for example, Japanese Patent Laid-Open No. 61-193897, and the description thereof is omitted here.
[0014]
FIG. 1 and FIG. 2 show the flow of processing of an automatic ticket gate and a commuter pass when a passenger gets on from A station. In the following description, it is assumed that the station names are in the order of A station, B station, C station, and D station on one route, and X station and Y station on other routes.
[0015]
Step 101
The automatic ticket gate uses its own passenger sensor, and if it detects that a passenger has arrived, it issues a command to 'send ID number' to the commuter pass.
[0016]
Step 102
In response to the command issued to the commuter pass from the automatic ticket checker in step 101, if the passenger has a commuter pass, the ID number unique to the commuter pass is sent to the automatic ticket checker, so that Determine whether the ticket gate has received. If it has been received, the process proceeds to step 103; otherwise, the process proceeds to step 101.
[0017]
Step 103
Since this passenger has a commuter pass, the instruction “ID number” and “report the boarding section” received in step 102 is sent from the automatic ticket gate to the commuter pass. The commuter pass that has received it confirms that the “ID number” is its own number, and then transmits its own “ID number” and “predetermined boarding section” to the automatic ticket gate. The automatic ticket gate reads them, and stores the “ID number” and “boarding section” in association with each other.
[0018]
Step 104
In the same procedure as in step 103, the automatic ticket checker reads the validity period of the commuter pass.
[0019]
Step 105
The automatic ticket gate sends a command “ID number” and “write the boarding station name and date and time” to the commuter pass. The commuter pass, after confirming its own “ID number”, writes the boarding station name and boarding date and time. Hereinafter, the boarding station name and the boarding date and time are collectively referred to as “boarding information”.
[0020]
Step 106
It is determined whether t ₁ seconds have elapsed since the passenger sensor started sensing. If t ₁ second has already elapsed, the process proceeds to step 107. If t ₁ second has not yet elapsed, the process returns to step 101 to search for another commuter pass.
[0021]
Step 107
If a ticket has been input to the automatic ticket gate, the process proceeds to step 108. Otherwise, go to step 110.
[0022]
Step 108
It is determined whether the input ticket is a ticket that can be boarded. If it is possible to get on the vehicle, the process proceeds to step 109;
[0023]
Step 109
Based on the “boarding section” and “valid period”, it is determined whether there is a commuter pass that can be boarded in the commuter pass detected by the automatic ticket gate. If there is a commuter pass that can be boarded, the process proceeds to step 115; otherwise, the process proceeds to step 114 because the boarding is performed only with a valid ticket.
[0024]
Step 110
As in step 109, it is determined whether there is a commuter pass that can be boarded among the commuter passes detected by the automatic ticket gate based on the “boarding section” and the “valid period”. If there is a commuter pass that can be ridden, the process proceeds to step 111. If not, neither the valid commuter pass nor the ticket is owned.
[0025]
Step 111
For passengers who have multiple commuter passes, a valid commuter pass (since this station is station A, for example, the boarding section is AB) and a commuter pass in which the section continues (for example, the boarding section is Check if there is (B-C station). Since information on boarding (boarding station name, boarding date and time) is written in all commuter passes in step 105, if there is such a commuter pass (in this case, a commuter pass for boarding section BC), go to step 113. move on. Otherwise, go to step 114.
[0026]
Step 112
Since the inserted ticket is invalid or does not have a valid commuter pass, the gate of the automatic ticket gate is closed and a sound is generated so that it cannot be boarded.
[0027]
Step 113
Since the passenger may get off at station C using this commuter pass, the automatic ticket gate clears the “boarding station name” stored in the commuter pass. Alternatively, if the boarding section of the commuter pass is from station B to station C, one of the station names may be written in “boarding station name”.
[0028]
Step 114
Since this passenger has a ticket that can be boarded or a valid commuter pass, he opens the gate of the automatic ticket gate and permits boarding.
[0029]
Step 115
Since this passenger boarded with a ticket while holding a commuter pass, it is checked whether the range in which the ticket can be taken and whether boarding sections of all commuter passes owned by the passenger are continuous. For example, if the valid section of the valid ticket is between (AC) and the boarding section of the commuter pass is between (C−D), it is determined that “the boarding section of the ticket and the commuter pass is continuous”. . Further, even if the boarding sections overlap (for example, “it is possible to ride to C station with a ticket” and “the boarding section of the commuter pass is from B station to D station”), it is considered to be continuous.
[0030]
On the other hand, if “the ticket boarding range is to B station” and “the commuter pass is from C station to D station”, it is determined that the ticket is not continuous. If the ticket and at least one commuter pass section are continuous, the process proceeds to step 116, and if the ticket and all commuter tickets are not continuous, the process proceeds to step 114.
[0031]
Step 116
The automatic ticket gate clears the “boarding station name” stored in the commuter pass that is continuous with the ticket. Alternatively, if the boarding section of the commuter pass is from station C to station D, one of the station names may be written in “boarding station name”.
[0032]
Table 1 shows an example in which the ticket gate that the automatic ticket checker has loaded and information on the commuter pass owned by the passenger are shown in Table 1.
[0033]
[Table 1]

[0034]
The commuter pass found by searching for and finding the commuter pass for the time t ₁ after the passenger sensor of the automatic ticket checker starts sensing is regarded as the commuter pass owned by the passenger. The example in Table 1 shows that two commuter passes were detected from passenger 1, one from passenger 2, and three from passenger 3. The number of passengers and the serial number may be incremented by 1 from the initial value 1 after the automatic ticket gate operates, as in this example, for example. The ID number is an ID number stored in the commuter pass. As described in FIG. 1, the commuter pass and the automatic ticket checker read and write information using this ID number as a key. Reading and writing information is the processing of steps 103, 104, 105, etc. in FIG. When the reading / writing process is completed, the “processed” flag is changed from 0 to 1. Here, although the commuter pass No. 6 has been detected, the reading / writing process has not been completed yet. A flag “ticket present” indicates whether each passenger has entered a valid ticket. If there is a valid ticket input, the section is described, and if not, “0” is described. The boarding section indicates a range where the commuter pass can be used. The valid period is a period during which the commuter pass can be used, but description of specific examples is omitted in the present invention.
[0035]
Except during rush hours, it is relatively easy to read a commuter pass owned by one passenger during time t ₁ . The problem is when two passengers appear in the automatic ticket gate at very short time intervals as in rush hour. For example, during the time you are reading a commuter pass of the passenger ₁ t 1, it is also conceivable that would read the commutation ticket of passengers 2. In such a case, since a passenger who is properly boarded cannot be suspected of illegal boarding, the following processing is performed.
[0036]
When the n-th passenger is checked (hereinafter referred to as “passenger n processing”) as in the process of FIG. 1, the commuter pass owned by the passenger is after the passenger (n−1) approaches the automatic ticket gate. Both the detected commuter pass and the commuter pass detected after passenger n approaches the automatic ticket gate are considered. In the example of Table 1, when passenger 2 is being processed, it is considered that “passenger 2 owns commuter pass serial numbers 1 to 3” (hereinafter, “commuter pass serial number n” is Expressed as ticket n '). If passenger 2 is only ticket for commuter pass 3 and boarding section A-C, since those sections are not continuous, there is a suspicion of illegal boarding, so write that commuter pass 3 got from station A . However, if the commuter pass 2 belongs to the passenger 2, the commuter pass is a normal ride, so the commuter pass 2 must not be written as “Get on from station A”. Thus, at the time of rush, the information of the commuter pass of the passenger before one is also read and the process of FIG. 1 is performed. Even if you write “Boarding from station A” on the commuter pass 2 when you process passenger 1, you can clear it if you know that you are riding normally when you process passenger 2, or from station C Write any station name up to station D. Therefore, 2 bits for the processed flag are provided at the time of rush. For example, the first bit of the processed flag of passenger (n-1) is used when processing passenger (n-1), and the second bit is used when processing passenger n.
[0037]
Similarly, when processing the passenger (n + 1), the commuter pass detected after the passenger n approaches the automatic ticket gate and the commuter pass detected after the passenger (n + 1) approaches the automatic ticket gate. Consider and process. In this way, passengers who are riding normally will not be disturbed. The rush mode or the normal mode may be switched by a controller from a controller connected to the automatic ticket gate, or automatically by software using a timer.
[0038]
FIG. 3 shows the flow of processing of the automatic ticket gate and the commuter pass when the passenger gets off at station A.
[0039]
Step 301
The automatic ticket gate uses its own passenger sensor, and when it detects that a passenger has arrived, it sends a command to the commuter pass, 'Send ID number'.
[0040]
Step 302
In response to the instruction issued to the commuter pass from the automatic ticket checker in step 301, if the passenger has a commuter pass, the ID number unique to the commuter pass is sent to the automatic ticket checker, so it is automatically Determine whether the ticket gate has received. If it has been received, the process proceeds to step 303; otherwise, the process proceeds to step 301.
[0041]
Step 303
Since this passenger has a commuter pass, the instruction “ID number” and “report the boarding section” received in step 302 is sent from the automatic ticket gate to the commuter pass. The commuter pass that has received it confirms that the “ID number” is its own number, and then transmits its own “ID number” and “predetermined boarding section” to the automatic ticket gate. The automatic ticket gate reads them, and stores the “ID number” and “boarding section” in association with each other.
[0042]
Step 304
Similar to step 303, the automatic ticket gate reads the validity period of the commuter pass.
[0043]
Step 305
Are there any contradictions in the boarding station and boarding date and time? Check. For example, even if the predetermined boarding section of this commuter pass is from station A to station B, if the boarding station name of the commuter pass is not this section, it is determined that there is a contradiction. If the boarding date and time is more than a predetermined time before the current time, it is determined that there is a contradiction in the boarding date and time, and NG is written in the OKorNG flag in Table 2, and OK is written if there is no contradiction.
[0044]
Step 306
It is determined whether t ₁ seconds have elapsed since the passenger sensor started sensing. If t ₁ second has already elapsed, the process proceeds to step 307. If t ₁ second has not yet elapsed, the process returns to step 301 to search for another commuter pass.
[0045]
Step 307
If a ticket has been input to the automatic ticket gate, the process proceeds to step 308. Otherwise, go to step 309.
[0046]
Step 308
It is determined whether the input ticket is a ticket that can be dismounted. If it is possible to get off, the process proceeds to step 310; otherwise, the process proceeds to step 314.
[0047]
Step 309
It is determined with reference to the OKorNG flag in Table 2 whether there is a commuter pass that can be disembarked among the commuter passes detected by the automatic ticket gate. If there is a commuter pass that can be taken off, the process proceeds to step 312; Needless to say, if the automatic ticket checker fails to detect any commuter pass, the process proceeds to step 314.
[0048]
Step 310
It is determined whether there is a commuter pass detected by the automatic ticket gate. If this passenger owns the commuter pass, the process proceeds to step 311, and if not, the process proceeds to step 313.
[0049]
Step 311
Since it is a normal boarding by ticket only, if the passenger has a commuter pass, the information on boarding all commuter passes is cleared.
[0050]
Step 312
Since it is a normal boarding, information on boarding of all commuter passes held by the passenger is cleared.
[0051]
Step 313
The passengers, which can get off the ticket, or, because it holds a commuter pass, opened the gate of the automatic ticket gate, admit get off.
[0052]
Step 314
Since there is no ticket or commuter pass that can be disembarked, the gate of the automatic ticket gate is closed and a sound is generated to prevent the passenger from getting off.
[0053]
In step 311 and step 312, it is described that the information related to the boarding is cleared. The necessity will be described. In FIG. 2, “If the ticket and the boarding section of the commuter pass are not continuous, write A station in the boarding station name of the commuter pass”. If you use a ticket valid from D station to C station and a commuter pass valid from B station to A station, get on the ticket from D station and get off using the commuter pass at A station, When this passenger gets off at station C using a ticket, it is normal. In this case, it is necessary to clear the boarding station name = D station written at the time of boarding. Step 311 corresponds to this. In addition, when a valid boarding is performed with a plurality of commuter passes, information on boarding of all commuter passes is cleared when getting off. Step 312 corresponds to this.
[0054]
Table 2 shows an example in which, in the case of a disembarkation, an automatic ticket checker reads information on tickets inserted by passengers and commuter passes owned by passengers.
[0055]
[Table 2]

[0056]
As in the case of boarding, the commuter pass detected for the time t _{1 after} the automatic ticket checker detects the passenger with the passenger sensor is considered as a commuter pass owned by the passenger.
[0057]
Passenger 1 has three commuter passes, and passengers 2 to 4 have two commuter passes. Since the passenger 1 got on from the D station, the commuter pass 1, 2, and 3 are written with the name of the boarding station as the D station. Step 305 determines that the passenger 1 can get off because the commuter pass 1 is present, and describes “OK” in the column of OKorNG. For other commuter passes, write 'NG'. In step 312, information on boarding of commuter passes 1, 2 and 3 is cleared.
[0058]
Passenger 2 has inserted a valid ticket, so the ticket flag is set to 1. The commuter passes 4 and 5 cannot be disembarked, but since a valid ticket is inserted between (AZ), it is possible to disembark. However, before getting off, information on boarding the commuter passes 4 and 5 is cleared at step 311.
[0059]
Passenger 3 got on a valid ticket from station C to (C-B). Since the section of the ticket and the commuter pass 7 is continuous, the boarding station name is described as B station in step 116. Therefore, it is determined that the commuter pass 7 can get off.
[0060]
Passenger 4 boarded with a valid ticket from D station to (DC), so commuter pass 8 and 9 recorded that boarding station = D station. However, when getting off, it is a so-called “Xelel” boarding that tries to get off with the commuter pass 8 without inserting the ticket. Even if you try to get off with the commuter pass 8, you will not be able to get off because the boarding station name is recorded as D station.
[0061]
As for OUTorIN, OUT has already gone out of the automatic ticket gate. This means that IN is still in the automatic ticket gate. In Table 2, since it is not directly related to the present invention, specific examples of the valid period and the boarding date and time are omitted.
[0062]
In this way, according to the present embodiment, not only is it prevented from getting on the ticket, but also distinguishes between passengers who use two or more commuter passes, or who normally ride using one ticket and one or more commuter passes. can do. Therefore, it is possible to find only passengers who have boarded illegally without causing trouble to passengers who have boarded normally.
[0063]
During rush hours, if passengers (n + 1) are processed as described in the case of boarding, is it possible to get off for all commuter passes that passengers n and passengers (n + 1) are likely to own? Determine whether or not. In the example of Table 2, if the commuter pass 7 is for the passenger 4, the passenger 4 gets off the vehicle.
[0064]
If automatic ticket gates are introduced in stages, not at all stations, the following points should be noted.
[0065]
(1) When there is no automatic ticket gate at the boarding station and there is a boarding station The boarding station name and boarding date and time are not written, so it is unknown when and where you boarded, but there is no evidence of illegal boarding. Admit.
[0066]
(2) If there is an automatic ticket gate at the boarding station and not at the getting-off station, the boarding station name and boarding date and time are not cleared and remain in the commuter pass. Thereafter, in the case of (1) above, the information at the time of getting off means that "I got on a few days ago". Therefore, in step 305, it is described whether or not there is a contradiction in the boarding date and time. However, it is necessary to make a determination such as “valid if a predetermined number of days have passed”.
[0067]
In addition, two railway companies may now allow the transfer at the transfer station without going through the ticket gate. Consider a case where a certain passenger has a commuter pass 1 valid between (A-B) and a valid commuter pass 2 between (B-C) and rides from A station to C station. If you change trains at station B without passing through the ticket gates, you cannot clear information related to boarding commuter pass 1, and you cannot write information about boarding on commuter pass 2. In such a case, a reader / writer for a non-contact IC card dedicated to a commuter pass should be installed in the communication passage of station B so that the passenger can pass with the commuter pass in the pocket and read and write the commuter pass. . This can be realized by the procedure from step 101 to step 105 and from step 301 to step 305. With this method, it is possible to remove the annoyance of “passing through an automatic ticket gate” to passengers, and to read and write information on correct boarding.
[0068]
Next, let us consider measures for passengers who get on from manned ticket gates without going through automatic ticket gates. A reader / writer for contactless IC cards is also installed at manned ticket gates to read and write commuter passes. Then, a ticket reader is installed on the station staff side, and the ticket is received from a passenger who shows the ticket to the station staff and gets on the ticket, and the ticket information is read by the installed ticket reader. In parallel with reading the ticket information, the reader / writer of the non-contact IC card checks whether the passenger has a commuter pass. This can be realized by the procedure shown in FIGS. The station clerk can act on behalf of the ticket gate instead of the automatic ticket gate, and the same processing as in FIGS. 1 and 2 is executed. For passengers who get off by showing a commuter pass at a manned ticket gate, it is possible to read information on boarding of the commuter pass with a reader / writer of a non-contact IC card to check whether it is normal boarding. If there is a passenger who gets out of the ticket gate at the manned ticket gate, the station staff inputs it into the ticket reader, and the reader / writer of the non-contact IC card searches whether this passenger owns the commuter pass. If you have a commuter pass, clear the information about the ride written on it. This can be realized by the procedure shown in FIGS. In this way, it is possible to find a passenger who makes an illegal ride through the manned ticket gate.
[0069]
As a second embodiment, a method will be described in which passengers get their commuter pass closer to the reading section of the automatic ticket gate when getting on and off. In this method, the passenger's concealment ticket is searched for when riding, so that the transmitter of the automatic ticket checker emits a strong radio wave as in the first embodiment. On the other hand, since it is sufficient to determine whether or not the boarding is normal with a commuter pass provided by the passenger when getting off, the sending part of the automatic ticket checker can detect the commuter pass with weaker radio waves than when boarding. According to this embodiment, since the passenger approaches the commuter pass to the automatic ticket gate, there is an effect that the automatic ticket gate can read the commuter pass correctly in the order of arrival of the passengers. As a demerit, when you get off, it will read and write with weak radio waves, so there is a possibility that you can not clear the information on boarding the commuter pass you own in your pocket, but when you get on the commuter pass this time, information on boarding with strong radio waves Should be written.
[0070]
A system has been announced that "you can get on and off with a contactless IC card in your pocket, transfer that information to the host computer, and later deduct the fare from the passenger's account." However, no countermeasure is described when one passenger owns a plurality of IC cards. Therefore, there is a problem that if the passenger 1 gets on his / her own IC card and the IC card of the passenger 2 for some reason, the fare is collected from the passenger 2 who is not on the board. In the third embodiment, a countermeasure for this case will be described. When boarding, if the automatic ticket checker determines that one passenger possesses a plurality of IC cards in the process of FIG. 1, information relating to boarding is written only to one IC card. In FIG. 1, “commuter pass” is described. Needless to say, in the third embodiment, “commuter pass” is replaced with “IC card”. There are two ways to get off. First, if it is detected that one passenger owns a plurality of IC cards in the same process as the boarding, all the IC cards (not limited to one) on which information on boarding is written are recorded. This is a method of recording the arrival and reporting it to the host computer. The second method is to record only one stop in an IC card in which information related to boarding is written and report it to the host computer. According to the present embodiment, it is possible to prevent a wrong operation of collecting a fare from a passenger who is not on board.
[0071]
【The invention's effect】
According to the present invention, it is possible to prevent unauthorized boarding even for passengers who have not only one but also a plurality of commuter passes.
