Description

本発明は、料金収受システムおよび料金収受システムの時刻修正方法に関する。   The present invention relates to a fee collection system and a time correction method of the fee collection system.

有料道路の料金の収受を電子的に行うＥＴＣ（Electronic Toll Collection)システムが用いられている（例えば、特許文献１参照）。
ＥＴＣシステムでは、料金所に設置されたＥＴＣ処理装置に接続された無線制御装置（端末装置）と車両に設置された車載装置間での通信によって、料金の収受処理を行う。
特願平７−９３６２４号公報 An ETC (Electronic Toll Collection) system that electronically collects toll road charges is used (see, for example, Patent Document 1).
In the ETC system, toll collection processing is performed by communication between a wireless control device (terminal device) connected to an ETC processing device installed at a toll booth and an in-vehicle device installed in a vehicle.
Japanese Patent Application No. 7-93624

ここで、端末装置がタイマを有し、このタイマの時刻が料金収受に用いられる場合がある。例えば、出口料金所に端末装置を設置したフリーフローＥＴＣシステムにおいて、夜間や環境ロードプライシングによる割引を実施する場合がある。この場合には、出口料金所での料金所収受処理時に車両の通過時刻を確認し、確認された時刻に応じて割引を実施する。
このように、端末装置のタイマの時刻が重要となる場合があることから、端末装置のタイマの時刻を自動的に修正できれば便宜である。これを実現するために、上位装置から端末装置に時刻情報を配信し、端末装置が配信された時刻情報に基づき時刻を自動的に修正することが考えられる。
しかしながら、上位装置から配信される時刻情報が誤っている場合には、端末装置のタイマが誤った時刻に設定される。その結果、例えば、割り引きが適用されるべき時間帯の収受処理に対して、割り引きが適用されない可能性が生じることになる。
上記に鑑み、本発明は時刻の修正の正確性の向上を図った料金収受システムおよび料金収受システムの時刻修正方法を提供することを目的とする。 Here, the terminal device may have a timer, and the time of this timer may be used for toll collection. For example, in a free flow ETC system in which a terminal device is installed at an exit toll gate, there may be a discount at night or due to environmental road pricing. In this case, the passing time of the vehicle is confirmed during the toll collection process at the exit toll gate, and a discount is implemented according to the confirmed time.
Thus, since the time of the timer of the terminal device may be important, it is convenient if the time of the timer of the terminal device can be automatically corrected. In order to realize this, it is conceivable that time information is distributed from the host device to the terminal device, and the time is automatically corrected based on the time information distributed by the terminal device.
However, when the time information distributed from the host device is incorrect, the timer of the terminal device is set to the incorrect time. As a result, for example, there is a possibility that the discount is not applied to the collection process in the time zone where the discount is to be applied.
In view of the above, an object of the present invention is to provide a toll collection system and a toll correction method for a toll collection system that improve the accuracy of time correction.

It is characterized by.

本発明に係る料金収受システムの時刻修正方法は、端末装置と、上位装置とを具備する料金収受システムの時刻修正方法であって、前記上位装置のタイマの時刻と、前記端末装置のタイマの時刻との差が所定範囲内であるか否かの時刻範囲判断を行うステップと、前記時刻範囲判断の結果に基づき、前記端末装置のタイマの時刻を修正するか否かの時刻修正可否判断を行うステップと、前記時刻修正可否判断の結果に基づき、前記端末装置のタイマの時刻を修正するステップと、を具備することを特徴とする。   A time collection method for a fee collection system according to the present invention is a time collection method for a fee collection system comprising a terminal device and a host device, wherein the timer time of the host device and the timer time of the terminal device are A time range determination as to whether or not the difference between the two is within a predetermined range, and based on the result of the time range determination, determine whether or not to correct the time of the timer of the terminal device And a step of correcting the time of the timer of the terminal device based on the result of the determination of whether or not the time can be corrected.

The timer measures time and can be used as a time reference for the entire ETC system 100. The time correction availability determination unit determines whether or not to correct the time. The transmission / reception unit transmits the time of the timer and the result of the determination of whether or not the time can be corrected, receives the result of the time range determination from the wireless control device 131, and the like.

ＥＴＣ処理装置１２１、保守端末１２２は、料金所に対応して配置される。この料金所は、入口、出口のいずれでも差し支えない。
ＥＴＣ処理装置１２１は、無線制御装置１３１からのデータを送受信し中央処理装置１１０にデータを送受信する。
保守端末１２２は、無線制御装置１３１のタイマの時刻を修正するための入力等が可能である。 The ETC processing device 121 and the maintenance terminal 122 are arranged corresponding to the toll gate. This toll booth can be at either the entrance or the exit.
The ETC processing device 121 transmits / receives data from the wireless control device 131 and transmits / receives data to / from the central processing device 110.
The maintenance terminal 122 can be input to correct the time of the timer of the wireless control device 131.

無線制御装置１３１、画像処理装置１３２，アンテナ１３３は車線に対応して配置される。即ち、車線が複数ある場合には、一つのＥＴＣ処理装置１２１の下に複数の無線制御装置１３１、画像処理装置１３２，アンテナ１３３が設置されることになる。例えば、入口料金所のブース毎に設置することができる。   The wireless control device 131, the image processing device 132, and the antenna 133 are arranged corresponding to the lane. That is, when there are a plurality of lanes, a plurality of wireless control devices 131, image processing devices 132, and antennas 133 are installed under one ETC processing device 121. For example, it can be installed for each booth at the entrance toll gate.

無線制御装置１３１は、端末機器として、アンテナ１３３を介して、車両に設置された車載装置との間で通信を行い、料金収受処理を行うものであり、図示しないタイマ、時刻範囲判断部、時刻修正部、送受信部、警報機を有する。タイマは時刻を計時するものであり、例えば、時刻に応じた割引料金の適用等に利用される。時刻範囲判断部は、中央処理装置１１０から受信した時刻と自己のタイマの時刻との差が所定範囲内であるか否かの時刻範囲判断を行う。時刻修正部は、中央処理装置１１０から受信した時刻修正可否判断の結果に基づいて、タイマの時刻の修正を行う。送受信部は、中央処理装置１１０からの時刻情報および時刻修正可否判断の結果の受信、および中央処理装置１１０への時刻範囲判断の結果の送信等を行う。警報機は、警報（異常報知信号）を出力する。

（ＥＴＣシステム１００の動作）
以下、ＥＴＣシステム１００の動作を説明する。
図２は、ＥＴＣシステム１００の動作手順の概略の一例を表すフロー図である。
図２は、ＥＴＣシステム１００全体での時刻の修正処理を行うための処理手順を表し、（１）上位装置（中央処理装置１１０）からの時刻の配信（ステップＳ１０）、（２）端末装置（無線制御装置１３１）での配信された時刻範囲の判断（ステップＳ２０）、（３）上位装置（中央処理装置１１０）での時刻修正可否の判断（ステップＳ３０）、（４）時刻修正可否の判断結果に基づく端末装置（無線制御装置１３１）での時刻修正処理（ステップＳ４０）が順に行われる。 (Operation of ETC system 100)
Hereinafter, the operation of the ETC system 100 will be described.
FIG. 2 is a flowchart showing an example of an outline of an operation procedure of the ETC system 100.
FIG. 2 shows a processing procedure for performing time correction processing in the entire ETC system 100. (1) Time distribution from the host device (central processing unit 110) (step S10), (2) Terminal device ( (3) Judgment of whether or not the time adjustment is possible (step S30), (4) Judgment of whether or not the time adjustment is possible (step S20) Time correction processing (step S40) in the terminal device (wireless control device 131) based on the result is sequentially performed.

図３〜６は、図２の処理内容の詳細を表すフロー図であり、それぞれ図２のステップＳ１０〜Ｓ４０に対応する。以下、詳細に説明する。
（１）中央処理装置１１０からの時刻の配信（ステップＳ１０）
中央処理装置１１０は、時刻配信時期が到来したときに（ステップＳ１１）、時刻を修正するための時刻修正情報を各無線制御装置１３１に向けて送信する（ステップＳ１２）。配信される情報には、時刻の修正に関わることを表す時刻修正関連情報と、修正後の時刻を表す時刻情報とが含まれる。
配信される時刻は、中央処理装置１１０のタイマの時刻に基づく。また、時刻配信時期の到来の判断は、例えば、所定の時間間隔、所定の時刻が到来したことに基づいて行える。 3 to 6 are flowcharts showing details of the processing contents of FIG. 2, and correspond to steps S10 to S40 of FIG. 2, respectively. Details will be described below.
(1) Time distribution from the central processing unit 110 (step S10)
When the time distribution time comes (step S11), the central processing unit 110 transmits time correction information for correcting the time to each radio control device 131 (step S12). The distributed information includes time correction related information indicating that the time is related to correction and time information indicating the time after correction.
The distribution time is based on the time of the timer of the central processing unit 110. The arrival of the time distribution time can be determined based on, for example, the arrival of a predetermined time interval and a predetermined time.

（２）無線制御装置１３１での配信された時刻範囲の判断（ステップＳ２０）
中央処理装置１１０から送信された時刻は、ＥＴＣ処理装置１２１を経由して、無線制御装置１３１で受信される（ステップＳ２１）。
無線制御装置１３１は中央処理装置１１０より時刻を受信した際、受信した時刻と無線制御装置１３１自身の時刻を比較し（ステップＳ２２）、二つの時刻の差がある一定範囲内であるかの判定（時刻範囲の判断）を行う（ステップＳ２３）。
無線制御装置１３１が受信した時刻と自身の時刻の差が一定範囲を超える場合は、中央処理装置１１０より受信した時刻が正しいか否か信頼性が低く、中央処理装置１１０が配信した時刻に基づいて自動的に時刻を修正するのは適切でないからである。
この二つの時刻の差が所定範囲内であれば判定結果「ＯＫ」を、一定範囲を超えていれば判定結果「ＮＧ」を、中央処理装置１１０に送信する（ステップＳ２４，Ｓ２５）。即ち、無線制御装置１３１から中央処理装置１１０に時刻範囲判断の結果が送信される。なお、この所定範囲として、例えば、１０秒、１５秒、３０秒等の時間範囲を採用することができる。 (2) Judgment of distributed time range in radio control apparatus 131 (step S20)
The time transmitted from the central processing unit 110 is received by the radio control unit 131 via the ETC processing unit 121 (step S21).
When receiving the time from the central processing unit 110, the wireless control device 131 compares the received time with the time of the wireless control device 131 itself (step S22), and determines whether the difference between the two times is within a certain range. (Time range determination) is performed (step S23).
If the difference between the time received by the wireless control device 131 and its own time exceeds a certain range, the reliability of whether the time received from the central processing unit 110 is correct is low and based on the time distributed by the central processing unit 110 This is because it is not appropriate to correct the time automatically.
If the difference between the two times is within a predetermined range, the determination result “OK” is transmitted to the central processing unit 110 if the difference is over a certain range (steps S24 and S25). That is, the result of time range determination is transmitted from the wireless control device 131 to the central processing unit 110. As this predetermined range, for example, a time range such as 10 seconds, 15 seconds, or 30 seconds can be employed.

（３）中央処理装置１１０での時刻修正可否の判断（ステップＳ３０）
中央処理装置１１０は、各無線制御装置１３１より送信された時刻比較判定結果情報を受信し（ステップＳ３１）、判定結果を集計する（ステップＳ３２）。即ち、中央処理装置１１０の配信時刻（無線制御装置１３１の受信時刻）と無線制御装置１３１自身の時刻の差が一定範囲を超えた無線制御装置１３１の台数をカウントする。 (3) Judgment of whether or not time correction is possible in central processing unit 110 (step S30)
The central processing unit 110 receives time comparison determination result information transmitted from each wireless control device 131 (step S31), and totals the determination results (step S32). That is, the number of radio control devices 131 in which the difference between the distribution time of the central processing unit 110 (the reception time of the radio control device 131) and the time of the radio control device 131 itself exceeds a certain range is counted.

中央処理装置１１０は、中央処理装置１１０の配信時刻に従い無線制御装置１３１の時刻を修正するか否かを判定する（ステップＳ３３）。
具体的には、以下のように判定（時刻修正可否の判断）がなされる。
無線制御装置１３１全体の台数に対し、二つの時刻の差が一定範囲を超えた無線制御装置１３１の台数の方が少ない場合には（判定結果「ＮＧ」台数 ＜ 判定結果「ＯＫ」台数）、中央処理装置１１０が配信した時刻を“正”とし中央処理装置１１０は無線制御装置１３１に対し「時刻修正可信号」を送信する（ステップＳ３３、Ｓ３４）。また、二つの時刻の差が一定範囲を超えた無線制御装置１３１の台数が、二つの時刻の差が一定範囲内の無線制御装置１３１台数以上の場合（判定結果「ＮＧ」台数 ≧ 判定結果「ＯＫ」台数）は、中央処理装置１１０が配信して時刻を“正”とせず中央処理装置１１０は無線制御装置１３１に対し「時刻修正否信号」を送信する（ステップＳ３３、Ｓ３５）。即ち、中央処理装置１１０は、時刻の修正を行うか否かの時刻修正可否判断の結果を送信する。 The central processing unit 110 determines whether or not to correct the time of the wireless control device 131 according to the distribution time of the central processing unit 110 (step S33).
Specifically, the determination (determination of whether or not time correction is possible) is made as follows.
When the number of wireless control devices 131 in which the difference between the two times exceeds a certain range is smaller than the total number of wireless control devices 131 (judgment result “NG” number <judgment result “OK” number), The time at which the central processing unit 110 delivers is “correct”, and the central processing unit 110 transmits a “time correction enable signal” to the radio control unit 131 (steps S33 and S34). In addition, when the number of wireless control devices 131 in which the difference between the two times exceeds a certain range is greater than or equal to the number of wireless control devices 131 in which the difference between the two times is within the certain range (determination result “NG” number ≧ determination result “ The number of “OK” is distributed by the central processing unit 110 and the time is not “correct”, and the central processing unit 110 transmits a “time correction rejection signal” to the wireless control device 131 (steps S33 and S35). That is, the central processing unit 110 transmits a result of whether or not to correct the time.

（４）時刻修正可否の判断結果に基づく無線制御装置１３１での時刻修正処理（ステップＳ４０）
無線制御装置１３１は、中央処理装置１１０から送信された時刻修正可否判断の結果を受信し（ステップＳ４１）、受信した時刻修正可否情報に対応する処理を行う（ステップＳ４２〜Ｓ４５）。 (4) Time correction processing in the wireless control device 131 based on the determination result of time correction possibility (step S40)
The wireless control device 131 receives the result of the time correction availability determination transmitted from the central processing unit 110 (step S41), and performs processing corresponding to the received time correction availability information (steps S42 to S45).

即ち、「時刻修正可信号」を受信した無線制御装置１３１は受信時刻に従い自身のタイマの時刻を修正する（ステップＳ４２〜Ｓ４３）。「時刻修正否信号」を受信した無線制御装置１３１は時刻修正をおこなわず、警報（異常報知信号）を出力する（ステップＳ４２、Ｓ４４）。
時刻修正をおこなわず警報を出力した無線制御装置１３１に対しては、保守端末１２２より時刻設定のための入力を行う（ステップＳ４５）。保守作業（手動）にて時刻設定を行う際に、保守端末１２２より遠隔から時刻設定を行えるようにして、道路の上方空間に建てられたガントリ上に設置された機器へのアクセスが不要となる。なお、この警報を中央処理装置１１０側で出力されるようにして、中央処理装置１１０から電話等の連絡手段で係員に時刻設定の指示を行ってもよい。 That is, the wireless control device 131 that has received the “time correction enable signal” corrects the time of its own timer according to the reception time (steps S42 to S43). Receiving the “time correction rejection signal”, the wireless control device 131 does not correct the time and outputs an alarm (abnormality notification signal) (steps S42 and S44).
An input for setting the time is performed from the maintenance terminal 122 to the wireless control apparatus 131 that has output an alarm without correcting the time (step S45). When setting the time in maintenance work (manual), the time can be set remotely from the maintenance terminal 122, and access to equipment installed on the gantry built in the space above the road becomes unnecessary. . The alarm may be output on the central processing unit 110 side, and the central processing unit 110 may instruct the staff to set the time using a communication means such as a telephone.

以上を纏めると以下のようになる。
（１）ＥＴＣシステム１００において、中央処理装置１１０が配信した時刻を無線制御装置１３１が受信し、自身のタイマの時刻を修正する。この結果、複数の無線制御装置１３１のタイマの時刻を自動的に修正できる。 The above is summarized as follows.
(1) In the ETC system 100, the wireless control device 131 receives the time distributed by the central processing unit 110, and corrects the time of its own timer. As a result, the timer times of the plurality of wireless control devices 131 can be automatically corrected.

（２）無線制御装置１３１は受信した時刻と自身のタイマの時刻を一旦比較し、比較結果がある一定範囲内であるかの判定を行い、この判定結果を中央処理装置１１０に送信する。中央処理装置１１０は受信した各無線制御装置１３１の判定結果を集計し、中央処理装置１１０の配信時刻と無線制御装置１３１自身の時刻の差が一定範囲を超えた無線制御装置１３１の台数をカウントする。さらに、カウント結果に従い、中央処理装置１１０の配信時刻による無線制御装置１３１の時刻を修正するかを判定し（いわば多数決による判定）、判定結果を各無線制御装置１３１に送信する。無線制御装置１３１は、受信した中央処理装置１１０からの判定結果が時刻修正可の場合に自身のタイマの時刻を修正する。   (2) The wireless control device 131 compares the received time with the time of its own timer, determines whether the comparison result is within a certain range, and transmits the determination result to the central processing unit 110. The central processing unit 110 counts the received determination results of each wireless control device 131, and counts the number of wireless control devices 131 in which the difference between the distribution time of the central processing device 110 and the time of the wireless control device 131 exceeds a certain range. To do. Furthermore, according to the count result, it is determined whether to correct the time of the wireless control device 131 based on the distribution time of the central processing unit 110 (so-called determination by majority vote), and the determination result is transmitted to each wireless control device 131. The wireless control device 131 corrects the time of its own timer when the received determination result from the central processing unit 110 can correct the time.

このようにして、中央処理装置１１０より配信される時刻が信頼性の低い場合は無線制御装置１３１のタイマの時刻が配信時刻に修正されることを防止するとともに、中央処理装置１１０より配信される時刻が信頼性の高い場合は無線制御装置１３１時刻が配信時刻に自動修正される。   In this way, when the time distributed from the central processing unit 110 is low in reliability, the time of the timer of the wireless control device 131 is prevented from being corrected to the distribution time, and distributed from the central processing unit 110. When the time is highly reliable, the time of the wireless control device 131 is automatically corrected to the distribution time.
