If the writing fails, the automatic ticket gate 2 transmits unwritten occurrence notification to a management server 3, and the management server 3 receiving the unwritten occurrence notification transmits unwritten relief notification including writing relief data to the whole or part of a plurality of automatic ticket gates 2. The automatic ticket gate 2 receiving the unwritten relief notification records the writing relief data, and re-determines the entry/exit state of the user based on the writing relief data if the entry/exit state of the user is determined as improper based on the read entry/exit data.

Description

  The present invention relates to an automatic ticket gate system and an automatic ticket gate for performing entrance processing or participation processing based on information recorded on an information recording medium.

  In recent years, automatic ticket gates that perform entry processing or entry processing (hereinafter referred to as “entrance / exit processing”) using an information recording medium such as an IC card having a wireless communication function are arranged at a ticket gate at a station. This type of automatic ticket gate reads predetermined information from the information recording medium when the information recording medium possessed by the user is positioned within the communication area of the automatic ticket gate, and the user's traffic is based on the read information. It is determined whether or not to permit. If the user's passage cannot be permitted, the user's passage is prevented by closing the door provided in the ticket gate passage. If the passage is permitted, new information is stored in the user's information recording medium. Write.

  For example, in Patent Document 1, as a result of arithmetic processing based on information read from a user's information recording medium, when entry / exit is not permitted or when entry / exit is permitted, An automatic ticket gate configured to close a door is disclosed. Here, incomplete writing means, for example, a signal indicating that the information has been written from the information recording medium after the information to be written to the information recording medium is transmitted from the automatic ticket checker to the information recording medium. Means that the communication between the two has been interrupted before receiving the message, in other words, that the automatic ticket checker has failed to write information to the information recording medium.

Japanese Patent Laid-Open No. 2004-220067

By the way, since the information recording medium moves together with the user, the information recording medium is in the automatic ticket gate while the automatic ticket gate is transmitting information to the information recording medium, that is, during the writing of information by the automatic ticket gate. It is difficult to completely prevent the occurrence of incomplete writing. For this reason, in the conventional automatic ticket gate, even when the user can be permitted to enter and exit, the door is closed with a certain frequency.
When the door of the automatic ticket gate is closed, subsequent users can no longer pass through the ticket gate passage, and as a result, the smooth passage of the user in the ticket gate passage is obstructed. On the other hand, it may be possible not to close the door when writing is not completed, but if writing fails, the door will be closed because it is determined that the entrance / exit state is not appropriate at the next entry / exit. Therefore, after all, the smooth passage of users in the ticket gate passage is hindered.

  The present invention has been made paying attention to the conventional problems as described above, and writing has not been completed in an automatic ticket gate system or automatic ticket checker that performs entry / exit processing using an information recording medium such as an IC card. The purpose of this is to prevent the smooth passage of users in the ticket gate passage from being obstructed.

An automatic ticket gate system according to one aspect of the present invention includes a plurality of automatic ticket gates that perform entry / exit processing based on information read from an information recording medium, and a management server that exchanges information with each of the plurality of automatic ticket gates. Each of the plurality of automatic ticket gates includes an information reading means for reading identification information and entrance / exit data from a user information recording medium, and an entrance / exit read by the information reading means. It is determined whether or not the user's entry / exit state is appropriate based on the data, and the determination unit that permits the user's passage when the user's entry / exit state is appropriate; Information writing means for writing new entrance / exit data on the information recording medium of the authorized user, and writing when entrance / exit data writing by the information writing means fails While sending to the management server a write incomplete occurrence notification including identification information of an information recording medium that has been lost and incompletely written and write incomplete data that is entry / exit data that has failed to be written, Information transmission / reception means for receiving an incomplete write relief notification including identification information and incomplete write data of an information recording medium in an incomplete write state from the management server;
Information recording means for recording the identification information of the information recording medium and the write incomplete data included in the received incomplete write relief notice, and the determination means is the entrance / exit read by the information reading means When it is determined that the user's entry / exit state is not appropriate based on the data, when the identification information that matches the identification information read by the information reading means is recorded in the information recording means, the information reading means The management server re-determines whether the entry / exit state of the user is appropriate based on the incomplete write data recorded in the information recording means instead of the entry / exit data read by the management server, Upon receipt of the write incomplete occurrence notification from at least one of the plurality of automatic ticket gates, identification of the information recording medium in the write incomplete state included in the write incomplete occurrence notification Transmitting the write incompletion remedies notice including the broadcast and write incompletion data to all or part of the plurality of automatic ticket gate.

  An automatic ticket checker according to another aspect of the present invention provides information reading means for reading identification information and entrance / exit data from an information recording medium, and the entrance / exit state of the user based on the entrance / exit data read by the information reading unit. It is determined whether or not it is appropriate, and when it is determined that the entrance / exit state of the user is appropriate, a determination unit that allows the user to pass, and an information record of the user permitted to pass by the determination unit An information writing means for writing new entry / exit data on the medium; and an information recording means for recording the identification information of the information recording medium inputted from the outside and the entry / exit data associated with the identification information, the determination The means determines the information read by the information reading means when it is determined that the entrance / exit state of the user is not appropriate based on the entrance / exit data read by the information reading means. When identification information that matches the information is recorded in the information recording means, instead of the entry / exit data read by the information reading means, based on incompletely written data recorded in the information recording means Re-determine whether the user's entry / exit status is appropriate.

  According to the automatic ticket checker system and the automatic ticket checker, if a write incomplete occurs at the time of entry / exit, a relief process is performed for the incomplete write at the next entry / exit, so the write incomplete There is no need to block user traffic each time this occurs. As a result, it is possible to greatly prevent the smooth passage of the user in the ticket gate passage due to the incomplete writing.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 shows a schematic configuration of an automatic ticket gate system according to an embodiment of the present invention. The automatic ticket gate system according to the present embodiment is installed at a ticket gate at a station and performs a plurality of automatic entry / exit processing based on information read from, for example, an IC card 10 (corresponding to the “information recording medium” of the present invention). A ticket gate 2 and a management server 3 that is connected to each of the plurality of automatic ticket gates 2 and exchanges information with each automatic ticket gate 2 are provided. Here, each of the plurality of automatic ticket gates 2 may be arranged at different stations, or a part or all of them may be arranged at the same station.

  The IC card 10 is a non-contact type IC card that operates by power transmitted from the automatic ticket checker 2, and as shown in FIG. 1, a wireless communication unit 11 that performs wireless communication with the automatic ticket checker 2 And a recording unit (memory) 12 for recording various information and a control unit 13 for controlling the operation of the IC card 10.

The wireless communication unit 11 receives various commands transmitted from the automatic ticket gate 2 (particularly, an IC card reader / writer 21b described later) and outputs the received commands to the control unit 13. The control unit 13 processes the received command and creates a response to the received command. The created response is transmitted to the automatic ticket gate 2 via the wireless communication unit 11.
In the recording unit 12, identification information for identifying and identifying the IC card 10, commuter pass section, commuter pass validity period, entrance or exit information written by the automatic ticket gate 2 (hereinafter referred to as “entrance / exit information”) In addition, the balance of electronic currency is recorded. Here, the entrance / exit information is information that is written into the IC card 10 by the automatic ticket gate 2 at the time of entry or entry, information on the station where the user of the IC card 10 entered or entered, information on the entry date / time or entry date / time. including. Here, it is assumed that the entry / exit information written at the last (most recent) is recorded in the recording unit 12. Although one recording unit 12 is shown in the figure, a plurality of recording units may be provided, and each piece of information may be recorded in separate recording units.

  FIG. 2 is a block diagram showing the configuration of the automatic ticket gate 2, and FIG. 3 is a perspective view of the automatic ticket gate 2. Here, a pair of automatic ticket gates are arranged in a reverse direction at a predetermined interval at the ticket gate of an actual station, and a user enters a ticket gate passage formed between the pair of automatic ticket gates. However, FIG. 3 shows only one of the automatic ticket gates 2 of the pair of automatic ticket gates, that is, when the user passes in the direction of the arrow in the figure. Only the automatic ticket gate 2 that performs entry processing is shown.

  As shown in FIGS. 2 and 3, the automatic ticket gate 2 includes a wireless communication unit 21 that performs wireless communication with the IC card 10, and a first door unit 22 that can be opened and closed provided on the entrance side of the ticket gate. The second door 23 that can be opened and closed provided on the exit side of the ticket gate, a traffic detection sensor 24 that detects a user passing through the ticket gate, and a guidance message for the user passing through the ticket gate are displayed. Received via the display unit 25, the speaker 26 that outputs a warning sound or the like when an abnormality occurs, the information transmission / reception unit 27 that exchanges information with the management server 3, and the wireless communication unit 21 and / or the transmission / reception unit 27 An information recording unit 28 that records (input) various information and a control unit 29 that controls various operations of the automatic ticket gate 2 are provided.

The wireless communication unit 21 performs wireless communication with the IC card 10 to read information from the IC card 10 and write information to the IC card 10. The wireless communication unit 21 is provided on the upper surface on the entrance side of the ticket gate passage of the automatic ticket gate 2. It includes an antenna 21a provided and an IC card reader / writer (indicated as “IC-R / W” in FIG. 2) 21b. Although not shown, a predetermined range above the antenna 21a is a communication area of the wireless communication unit 21 (that is, the automatic ticket gate 2). The wireless communication unit 21 (automatic ticket gate 2) can read and write information with respect to the IC card 10 located in the communication area. The 1st door part 22 and the 2nd door part 23 block a user's passage (pass of a ticket gate) at the time of closing operation. The traffic detection sensor 24 is, for example, a transmission type photosensor, and is provided on the inner surface of the automatic ticket gate 2 at a predetermined interval, and can detect the presence or absence of a user and the passage of the user.
The operation of the wireless communication unit 21, the second door unit 23, the display unit 25, the speaker 26, and the transmission / reception unit 27 is controlled by the control unit 29, and the operation of the first door unit 22 is an automatic ticket gate arranged with a ticket gate passage in between. This is controlled by a control unit of the other automatic ticket gate (not shown) of the pair of automatic ticket gates.

The automatic ticket gate 2 according to the present embodiment operates as follows based on the control by the control unit 29, for example.
First, the automatic ticket gate 2 sends out a polling command for capturing the IC card 10 through the wireless communication unit 21 in a fixed period in the standby state. The IC card 10 located in the communication area is recognized by receiving a response to the polling command from the IC card 10. Upon recognizing the IC card 10, the automatic ticket gate 2 transmits a mutual authentication command to the IC card 10 via the wireless communication unit 21 and receives a response to the mutual authentication command from the IC card 10. Mutual authentication with This mutual authentication is not particularly limited, but is performed by, for example, a common key cryptosystem. When the mutual authentication is performed, the automatic ticket gate 2 can read information from the IC card 10 and write information to the IC card 10 via the wireless communication unit 21.

Thereafter, the automatic ticket gate 2 reads the information recorded on the IC card 10 via the wireless communication unit 21 and determines whether or not to allow the user carrying the IC card 10 to pass based on the read information. Determine whether. Such determination is performed by the control unit 29. Specifically, the control unit 29 determines whether to allow the user to pass based on the entrance / exit information read from the IC card 10 and the balance of the electronic currency.
As a result of the determination, if the user's passage is not permitted, the control unit 29 closes the second door portion 23 to block the user's passage and causes the display unit 25 to display a predetermined message. Then, a warning sound is output from the speaker 26. On the other hand, when permitting the passage of the user, the control unit 29 causes the wireless communication unit 21 to write information to the IC card 10. The information written in the IC card 10 is, for example, new entrance / exit information or a balance obtained by subtracting the usage fee from the electronic currency balance (hereinafter simply referred to as “balance after subtraction”).

  In addition, when the controller 29 fails to write the new entry / exit information and the balance after the subtraction to the IC card 10, that is, the write command for the new entry / exit information and the balance after the subtraction is sent to the IC card 10. If communication with the IC card 10 is interrupted after transmission to the card 10 and before receiving a response to the write command, it is determined that writing failure, that is, writing incomplete has occurred. When it is determined that writing has not been completed, the control unit 29 writes the identification information of the IC card 10 in the writing incomplete state and the writing incomplete data that has failed to be written to the IC card 10. An incomplete occurrence notification is created and transmitted to the management server 34 via the information transmission / reception unit 27. At this time, the second door portion 23 is not closed and the user is allowed to pass.

Further, when receiving a write incomplete relief notification (to be described later) from the management server 34, the control unit 29 identifies the IC card identification information and write incomplete data (hereinafter referred to as “ The data for writing relief ”is recorded in the information recording unit 28, and the incomplete writing relief process is executed using the information recorded in the information recording unit 28 during the entrance / exit process. When the incomplete write relief process is executed, a relief process execution notification including the identification information of the IC card that has undergone the relief process is created and transmitted to the management server 34 via the information transmitting / receiving unit 27.
Therefore, in the automatic ticket gate 2 according to the present embodiment, the wireless communication unit 21 (more specifically, the IC card reader / writer 21b) corresponds to the “information reading unit” and the “information writing unit” in the present invention, and the control unit 29 Corresponds to “determination means” in the present invention, the information transmission / reception unit 27 corresponds to “information transmission / reception means” in the present invention, and the information recording unit 28 corresponds to “information storage means” in the present invention. The display unit 25 and the speaker 26 correspond to the “notification unit” of the present invention, the second door unit 23 corresponds to the “door unit” of the present invention, and the control unit 29 corresponds to the “door control unit” of the present invention. Equivalent to.

Returning to FIG. 1, the management server 3 manages the processing data and the like of each automatic ticket checker 2 and provides information necessary for entry / exit processing to each automatic ticket checker 2, as shown in FIG. , An information transmitting / receiving unit 31 that exchanges information with each automatic ticket gate 2, an information recording unit 32 that records various information including information necessary for entrance / exit processing, and a control that controls the operation of the management server 3 Unit 33.
When the management server 3 receives the write incomplete occurrence notification from at least one of the plurality of automatic ticket gates 2, the IC card 10 in the write incomplete state included in the write incomplete occurrence notification A write incomplete relief notice including the identification information and the incomplete write data as relief data is created, and this write incomplete relief notice is transmitted to all of the plurality of automatic ticket gates 2 to obtain a plurality of automatic ticket gates. One of the machines 2 is caused to execute a write incomplete relief process.

Next, each process executed in the automatic ticket gate system configured as described above will be described with reference to flowcharts.
4 to 6 are flowcharts showing entrance / exit processing executed in the automatic ticket checker 2, and is started when a response to a polling command transmitted at a constant cycle is received from the IC card in a standby state.
4 to 6, an IC card is detected in step S1. That is, when a response to the polling command is received from an IC card that has entered the wireless area, it is detected that the IC card has entered the communication area.

  In step S2, mutual authentication is performed with the detected IC card. This mutual authentication is performed, for example, when the automatic ticket checker 2 transmits a mutual authentication command to the IC card via the wireless communication unit 21 and receives a response to the transmitted mutual authentication command from the IC card. As described above, after mutual authentication is performed, the automatic ticket gate 2 can read information from the IC card and write information to the IC card.

  In step S3, information recorded on the IC card is read. To read this information, the automatic ticket gate 2 transmits a read command to the IC card via the wireless communication unit 21, and the IC card 10 that has received this read command reads the information from the specified address in the memory 12 and automatically checks the ticket. This is done by transmitting to the machine 2. Here, the identification information, entrance / exit information, and electronic currency balance recorded in the IC card 10 are read.

In step S4, it is determined whether the entry / exit state of the user carrying the IC card is appropriate. This determination is made based on the information read in step S3, and when the entrance / exit sequence is normal and the electronic currency balance is equal to or higher than the usage fee, it is determined that the user's entrance / exit state is appropriate. When the entrance / exit sequence is abnormal or when the balance of the electronic currency is less than the usage fee, it is determined that the entrance / exit state of the user is not appropriate. The automatic ticket gate 2 permits the user to pass if the entrance / exit state is appropriate, and does not allow the user to pass if the entrance / exit state is not appropriate.
Here, the case where the entrance / exit sequence is abnormal means, for example, a case where an attempt is made to enter with an IC card in which entry information is not recorded or an attempt is made to enter with an IC card without entry information recorded. . Moreover, as the usage fee, for example, a section fare or a minimum section fare from an entry station to a departure station is applicable. In this embodiment, the automatic ticket gate 2 at the participating station compares the balance of the electronic currency with the section fare, and the automatic ticket gate 2 at the entrance station compares the balance of the electronic currency with the minimum section fare. To do.
And if a user's entrance / exit state is appropriate, it will progress to step S5, and if a user's entrance / exit state is not appropriate, it will progress to step S8 (FIG. 5).

  In step S5, the new entry / exit information and the balance after subtracting the usage fee from the electronic currency balance read in step 3 are written in the IC card. Information is written to the IC card by the automatic ticket checker 2 transmitting a write command to the IC card via the wireless communication unit 21. Note that writing of the balance after the subtraction in this step is usually performed by the automatic ticket gate 2 at the participating station.

  In step S6, it is determined whether or not the writing of information to the IC card is completed. When a response to the transmitted write command is received from the IC card, it is determined that the writing of information to the IC card is completed, and the process proceeds to step S7 to return to the standby state. On the other hand, if communication with the IC card is interrupted before receiving a response to the transmitted write command (the IC card moves out of the communication area), it is determined that writing has not been completed and step S17 (FIG. Go to 6).

  In step S8 (FIG. 5), it is determined whether or not write relief data is recorded in the information recording unit. As described above, the write relief data is the identification information and the write incomplete data of the IC card in the write incomplete state, which is included in the write incomplete relief notification received from the management server 3. These are recorded in the information recording unit 28 associated with each other. If at least one write relief data is recorded in the information recording unit 28, the process proceeds to step S9. If not recorded, the process proceeds to step S16.

In step S9, the IC card identification information is collated. That is, the identification information read in step S3 is compared with the identification information recorded in the information recording unit 28.
In step S10, it is determined whether or not the identification information that matches the identification information read in step S3 is recorded in the information recording unit 28. If the identification information that matches the identification information read in step S3 is stored in the information recording unit 28, the process proceeds to step S11. If the identification information is not recorded in the information recording unit 28, the process proceeds to step S16.

  In step S11, unwritten data associated with the identification information that matches the identification information read in step S3 is read from the information recording unit 28. The incomplete data to be read is new entry / exit information, or both new entry / exit information and the balance after subtraction.

In step S12, it is re-determined whether or not the user entry / exit state is appropriate. Such re-determination is performed based on the incompletely written data read in step S11. That is, the determination in step S4 is made based on the information read from the IC card in step S3, but the determination in this step is the document recorded in the information recording unit 28 instead of the information read from the IC card in step S3. Based on incomplete data.
As a result of the re-determination, if the user entry / exit state is appropriate, the process proceeds to step S13, and if the user entry / exit state is not appropriate, the process proceeds to step S16.

  In step S13, the new entry / exit information and the balance after subtraction obtained by subtracting the usage fee from the balance of the electronic currency in the incompletely written data are written to the IC card. Information writing to the IC card is performed by transmitting a write command to the IC card, as in step S5. The writing of the balance after the subtraction in this step is usually performed by an automatic ticket gate at the entrance station.

  In step S14, it is determined whether or not the writing of information to the IC card is completed. When a response to the transmitted write command is received from the IC card, it is determined that the writing of information to the IC card is completed, and the process proceeds to step S15. On the other hand, if communication with the IC card is interrupted before receiving a response to the transmitted write command (the IC card moves out of the communication area), it is determined that writing has not been completed and step S17 (FIG. Go to 6).

  In step S15, a relief process notification is created and transmitted to the management server 3. This relief processing notification indicates that the incomplete write relief processing has been executed for the IC card that has been in an incomplete write state, and the user's entry / exit state is determined by redetermination based on the incomplete write data. It includes identification information of an IC card determined to be appropriate, that is, a rescued IC card. Then, after the relief processing notification is transmitted to the management server 3, the process proceeds to step S7, and the automatic ticket gate 2 returns to the standby state.

  In step S16, the user's passage is blocked. In the present embodiment, the second door portion 23 is closed, a predetermined message is displayed on the display unit 24, and a predetermined warning sound is output from the speaker 26. In addition, this traffic blocking state is continued until it is canceled by, for example, a station staff.

  In step S17 (FIG. 6), the user is informed that writing has not been completed, that is, writing of information to the IC card has failed. Specifically, a message for requesting the IC card to be positioned again in the communication area (re-holding request message) is displayed on the display unit 25 and a predetermined warning sound is output from the speaker 26. In addition, since the 2nd door part 23 is not closed here, the user can pass the automatic ticket gate 2. FIG.

  In step S18, a polling command and a mutual authentication command are sent alternately. That is, mutual authentication with an IC card that has failed to be written and is in an incomplete writing state and capture of the IC card of the subsequent user are performed in parallel. This is because, when an IC card that has not been written is positioned again in the communication area, information that has failed to be written to the IC card (see step S5 or step S13) can be rewritten. This is to improve the processing efficiency of the automatic ticket gate 2 by making it possible to capture an IC card possessed by another user.

  In step S19, it is determined whether a response to the mutual authentication command has been received from the IC card that has not been written. If a response to the mutual authentication command is received, the process proceeds to step S20. If a response to the mutual authentication command is not received, the process proceeds to step S21. When a response to the polling command is received from a new IC card regardless of whether or not a response to the mutual authentication command is received, the automatic ticket checker 2 is the same as this flow for the new IC card. Processing is performed in parallel.

  In step S20, information that failed to be written is rewritten to the IC card that has not been written. In this case, since the user recognizes that the information writing has failed, the information rewriting hardly occurs. And after rewriting information, it progresses to step S7 and the automatic ticket gate 2 returns to a standby state.

  In step S21, it is determined whether or not the user has passed through the automatic ticket gate 2. This determination is made based on the output of the traffic detection sensor 24. If the user passes the automatic ticket gate 2, the process proceeds to step S22. On the other hand, if the user has not passed the automatic ticket checker 2, the process returns to step S17, and the notification of the incomplete writing and the alternate sending of the polling command and the mutual authentication command are continued.

  In step S <b> 22, a writing incomplete notification is generated and transmitted to the management server 3 via the information transmitting / receiving unit 27. As described above, the write incomplete occurrence notification includes identification information of an IC card that has failed to write information and is in an incomplete write state, and write incomplete data that has failed to be written to the IC card. Then, after the writing completion notification is transmitted to the management server 3, the process proceeds to step S7, and the automatic ticket gate 2 returns to the standby state.

FIG. 7 is a flowchart showing a first process executed by the management server 3. This first process is to output a write incomplete relief command for relieving an IC card in an unfinished state to each automatic ticket checker 2, and write from at least one of the plurality of automatic ticket checkers 2. The process is started when an incomplete notification of occurrence (see step S22 in FIG. 6) is received.
In FIG. 7, in step S31, IC card identification information and write incomplete data are extracted from the received write incomplete occurrence notification.
In step S32, a write incomplete relief notification including the IC card identification information and write incomplete data extracted in step S31 as write relief data is created. This incomplete write relief notification is generated for each IC card identification information, and functions as an incomplete write relief command for the automatic ticket gate 2.
In step S <b> 33, the created incomplete write relief notice is transmitted to all of the plurality of automatic ticket gates 2.

FIG. 8 is a flowchart showing the recording process of the write relief data in the automatic ticket checker 2, and is started when a write incomplete relief notification (see step S33 in FIG. 7) is received from the management server 3.
In FIG. 8, in step S41, write relief data included in the received write incomplete relief notification, that is, identification information of the IC card in the write incomplete state and its write incomplete data are extracted.
In step S42, the write relief data extracted in step S41 is recorded in the information recording unit 28. If write relief data having the same identification information already exists in the information recording unit 28, the data is updated.
As a result, the automatic ticket gate 2 can perform processing (see FIG. 5) based on the write relief data recorded in the information recording unit 28 during the entrance / exit processing, and is in an incomplete writing state. A relief process for the IC card can be executed.

FIG. 9 is a flowchart showing the second process executed by the management server 3. This second process is to output a release command for canceling the incomplete write relief command to each automatic ticket checker 2, and from at least one of the plurality of automatic ticket checkers 2, a relief processing notification (FIG. 5). The process is started upon receiving (see step S15).
In FIG. 9, in step 51, identification information of the IC card included in the received relief processing notification, that is, the rescued IC card is extracted.
In step S52, a repair completion notification including the identification information of the IC card extracted in step S51 is created. This relief completion notification functions as a release command for canceling the incomplete write relief command for the automatic ticket gate 2.
In step S53, the created repair completion notification is transmitted to all of the plurality of automatic ticket gates 2.

FIG. 10 is a flowchart showing the erasure processing of the write relief data in the automatic ticket checker 2 and is started when a relief completion notification (see step S53 in FIG. 9) is received from the management server 3.
In FIG. 10, in step S61, the identification information of the IC card included in the received repair completion notification, that is, the identification information of the repaired IC card is extracted.
In step S62, the write relief data having the identification number that matches the identification information of the IC card extracted in step S61 is erased (cleared).

The automatic ticket gate system (automatic ticket gate) described above has the following effects.
Even if the automatic ticket checker fails to write to the IC card and the write is not complete, the automatic ticket checker does not close the door (does not block the user's traffic), so the write has not been completed. Occurrence does not hinder the smooth passage of users in the ticket gate.

  Even if it passes through the automatic ticket gate in an unfinished state, relief processing (that is, re-determination of passage permission and writing of unfinished data) is performed at the next entry / exit. This reduces the number of cases where traffic is not permitted at the next entry / exit due to the incomplete writing. As a result, it is possible to significantly suppress the occurrence of unfinished writing from being an obstacle to smooth passage in the ticket gate passage.

  When the incomplete writing occurs, the fact is notified and the mutual authentication command and the polling command are alternately sent. Therefore, when the user places the IC card in the communication area again. While allowing information to be rewritten, processing for the next user's IC card can also be started.

  Since the management server sends the incomplete write relief notice and the relief completion notice to all automatic ticket gates, it is different from the station where the write incomplete occurred, as well as the automatic ticket gate of the station where the write incomplete occurred. It is possible to carry out the incomplete relieving process by the automatic ticket checker at the station, and it is possible to prevent the same relief process from being executed by a plurality of automatic ticket checkers.

In the above-described embodiment, an IC card is used as the information recording medium, but it goes without saying that a portable terminal with an IC card function may be used.
Further, in the above-described embodiment, the write incomplete occurrence notification transmitted from the automatic ticket checker to the management server and the write incomplete relief notification transmitted from the management server to the automatic ticket checker are in a write incomplete state. The identification information of the IC card and incompletely written data that failed to be written are included. However, the present invention is not limited to this, and the both notifications may further include, for example, a date and time when writing failed. In this way, by comparing the entrance / exit information read from the IC card with the date and time when the writing failed, it is possible to effectively prevent the rescue process from being erroneously performed.

  Furthermore, in the above-described embodiment, the user's entry / exit state (whether or not the user is permitted to pass) is determined based on the entry / exit information read from the IC card and the balance of the electronic currency. However, when the IC card is used as a commuter pass, the user's entry / exit state may be determined based only on the entry / exit data read from the IC card. In this case, the processing related to the balance of the electronic currency in the above-described embodiment becomes unnecessary. That is, the “entrance / exit data” in the present invention includes a case where both the entrance / exit information and the balance of the electronic currency are included, and a case where only the entrance / exit information is included.

  Furthermore, in the above-described embodiment, the management server transmits the incomplete write relief notification and the repair completion notification to all of the plurality of automatic ticket gates. However, the management server transmits to a part of the plurality of automatic ticket gates. It may be. For example, the management server has a function of storing information on the used station for each identification information of the IC card, and the write incomplete relief is performed only on the automatic ticket gates arranged at stations with high usage frequency (above the judgment threshold). A notification may be transmitted, or an incomplete write relief notification may not be transmitted to an automatic ticket gate other than the automatic ticket gates located at stations with no usage record. In this way, the automatic ticket gate does not need to record more information than necessary, and can efficiently perform relief processing for incomplete writing.
