Description

The present invention relates to technology related to ticket processing at automatic ticket gates installed at station ticket gates.

Conventionally, electric railway companies use automatic ticket gates installed at the ticket gates of stations to process tickets for users entering and exiting the station premises.

Recently, thin client ticket gate systems are being considered, in which multiple automatic ticket gates are connected to a server via a network, and this server controls the connected multiple automatic ticket gates (for example, (See Patent Document 1). In this thin client type ticket gate system, a server instructs an automatic ticket gate to read/write ticket information on an IC card as a ticket medium. This server also calculates fares, determines whether or not the ticket gate passageway is passable, and notifies the automatic ticket gate of the results. In other words, the automatic ticket gate operates according to instructions from the server without calculating fares or determining whether or not the ticket gate is passable.

Unexamined Japanese Patent Publication No. 2019-46352

However, in the thin-client ticket gate system described in Patent Document 1, many automatic ticket gates installed at multiple stations are connected to a server, so the server may go down due to a failure, for example. When a failure occurs in the network used for communication between the server and the automatic ticket gate, the automatic ticket gate becomes unable to communicate with the server. Therefore, if the server goes down due to a failure, or if a failure occurs in the network used for communication between the server and the automatic ticket gates, the automatic ticket gates will stop working at multiple stations. In this case, the ticket inspection process for the user is stopped, resulting in a situation where the user cannot enter or exit the station premises, reducing convenience for the user.

Note that even if communication between the host server and the automatic ticket gate is interrupted, train service will not be stopped.

An object of the present invention is to provide a technology that can prevent the user's convenience from being degraded even if a communication failure occurs between a host server and an automatic ticket gate.

The automatic ticket gate of the present invention is configured as shown below in order to achieve the above object.

The medium processing section reads the identification code of the ticket medium held over the reading area by the user passing through the ticket gate passage. The communication unit transmits the identification code of the ticket medium read by the medium processing unit to the higher-level server, and receives a processing result including a determination result of whether or not the user can pass through the ticket gate passage from the higher-level server. The traffic control unit restricts the passage of users through the ticket gate passage based on the processing result received by the communication unit.

Further, the communication state detection unit detects whether the communication unit is in a poor communication state where it cannot communicate with the host server. For example, when the higher-level server is down due to a failure, or when a failure occurs in the network used to communicate with the higher-level server, the communication unit cannot communicate with the higher-level server.

The traffic control unit stores unprocessed traffic information including the identification code of the ticket medium read by the medium processing unit in the unprocessed traffic information storage unit when the communication state detection unit detects a poor communication state. and allow users to pass through the ticket gates. Furthermore, when the communication state detection section detects that the poor communication state has been resolved, the communication section transmits the unprocessed traffic information stored in the unprocessed traffic information storage section to the higher-level server.

According to this configuration, even if the higher-level server goes down due to a failure or the network used to communicate with the higher-level server has a failure, resulting in a communication failure that prevents communication with the higher-level server, , the user can pass through the ticket gate by holding the ticket medium over the reading area. Therefore, the user's convenience is not reduced. In addition, when the poor communication condition is resolved, the information of the users who passed through the ticket gate passage during the period of poor communication condition (unprocessed traffic information) is sent to the higher-level server, so the higher-level server can check the section used by the user. Can be obtained appropriately.

In addition, for example, when the communication status detection unit detects that there is no poor communication, the media processing unit applies an identification code to the ticket media located within the reading area in accordance with a reading instruction from the host server. A configuration in which, when reading is performed and the communication state detection unit detects a poor communication state, the identification code is repeatedly read from the ticket medium located within the reading area at a predetermined timing. You can also do this.

Further, in this case, the communication state detection unit may be configured to detect a poor communication state when the reading instruction from the host server is interrupted for a period exceeding a threshold time.

Further, the medium processing section may be configured to write usage information included in the processing result received from the host server by the communication section onto the ticket medium, for example.

In this case, the usage information included in the processing result may be encrypted, and the medium processing section may write the encrypted usage information on the ticket medium.

The host server also includes, for example, a usage history storage unit that stores the identification code of the ticket medium and the usage history of the ticket medium in association with each other, and the identification code of the ticket medium sent from the automatic ticket gate. When receiving the ticket, it refers to the usage history of the corresponding ticket medium stored in the usage history storage unit and sends the processing result including the determination result of whether or not the user can pass through the ticket gate passageway to the automatic ticket gate. and a usage history updating unit that updates the usage history of the corresponding ticket medium stored in the usage history storage unit according to the processing result transmitted by the communication unit to the automatic ticket gate. do it.

With this configuration, the user's usage history can be managed by the higher-level server.

Further, it is preferable that the usage history updating unit is configured to update the usage history of the corresponding ticket medium in accordance with the unprocessed traffic information when the communication unit receives the unprocessed traffic information.

According to this invention, even if there is a communication failure state in which communication cannot be performed between the host server and the automatic ticket gate, it is possible to prevent the user's convenience from being degraded.

<1. Application example＞
FIG. 1 is a schematic diagram showing the configuration of a ticket gate system according to this example. The ticket gate system in this example is a thin client type ticket gate system. The ticket gate system of this example includes a determination server 1 and a plurality of automatic ticket gates 5. The determination server 1 corresponds to the upper level server in the present invention.

Automatic ticket gates 5 are installed at ticket gates of multiple stations. In FIG. 1, two stations, A station and B station, are illustrated. A plurality of automatic ticket gates 5 installed at each station are connected to the determination server 1 via a network 3.

The determination server 1 instructs the automatic ticket gate 5 to read the ticket information stored in the IC card as the ticket medium and to write the ticket information to the IC card. An identification code for identifying the IC card and ticket information are recorded on the IC card. Although the identification code recorded on the IC card is not encrypted, the ticket information recorded on the IC card is encrypted.

The automatic ticket gate 5 does not store a decoding key for decoding encrypted ticket information. Therefore, the automatic ticket gate 5 cannot decode the ticket information read from the IC card. However, the automatic ticket gate 5 can obtain the identification code of the IC card since it is not encrypted. The automatic ticket gate 5 transmits the identification code read from the IC card and ticket information (encrypted ticket information) to the determination server 1.

The determination server 1 decodes the ticket information received from the automatic ticket gate 5, performs fare calculations for the user, encrypts the ticket information to be written on the IC card, and notifies the automatic ticket gate 5 of the same. The automatic ticket gate 5 writes the ticket information (encrypted ticket information) notified from the determination server 1 into the IC card. The determination server 1 also notifies the automatic ticket gate 5 of the determination result of whether or not the user can pass through the ticket gate passage. The automatic ticket gate 5 controls the passage of users through the ticket gate passage according to the judgment result of passability notified from the judgment server 1 (opening/closing of the door located on the exit side of the ticket passage for this user). ). Further, the determination server 1 stores the usage history of each IC card.

In the ticket gate system of this example, the automatic ticket gate 5 is in a communication failure state where it is unable to communicate with the determination server 1 because the determination server 1 is down due to a failure or a failure occurs in the network 3. If something is detected, the identification code is read from the user's IC card. The automatic ticket gate 5 allows the user who owns the IC card whose identification code has been read to pass through the ticket gate passage, and stores unprocessed passage information including the identification code of the IC card read this time.

Therefore, in the ticket gate system of this example, even when there is a communication failure in which communication is not possible between the judgment server 1 and the automatic ticket gate 5, the user cannot enter the station premises or leave the station premises. Therefore, it is possible to prevent the user's convenience from being degraded.

Further, when the poor communication state is resolved, the automatic ticket gate 5 transmits unprocessed traffic information including the identification code of the IC card read during the poor communication state to the determination server 1. By processing the unprocessed traffic information, the determination server 1 can acquire the identification code of the IC card owned by the user who passed through the ticket gate passage of the automatic ticket gate 5 when there was a communication failure state. In other words, the determination server 1 can appropriately acquire the usage section of the user even if a communication failure occurs.

<2. Configuration example>
FIG. 2 is a block diagram showing the configuration of the main parts of the determination server. The determination server 1 includes a control unit 11, a usage history database 12 (usage history DB 12), an unprocessed traffic information storage section 13, and a communication unit 14.

The control unit 11 controls the operation of each part of the main body of the determination server 1. The control unit 11 also includes a fare calculation section 11a, an unprocessed determination section 11b, a processing result generation section 11c, and a usage history update section 11d. The fare calculation unit 11a, unprocessed determination unit 11b, processing result generation unit 11c, and usage history update unit 11d included in the control unit 11 will be described later.

The usage history DB 12 is a database in which usage history of the IC card is registered for each IC card (for each IC card identification code). The usage history is a record of usage data indicating usage details for each use of the IC card. The usage data includes, for example, the date and time of usage, the station used, the type of entry/exit, and the value balance at that time. The unprocessed traffic information storage unit 13 stores the unprocessed traffic information notified from the automatic ticket gate 5. The communication unit 14 controls communication with the automatic ticket gate 5.

The fare calculation unit 11a, unprocessed determination unit 11b, processing result generation unit 11c, and usage history update unit 11d included in the control unit 11 will be described.

The fare calculation unit 11a calculates the fare for the section of railway used by the user. The unprocessed determining unit 11b determines whether the unprocessed traffic information of the identification code of the IC card to which the ticket information has been transmitted from the automatic ticket gate 5 is stored in the unprocessed traffic information storage unit 13. The processing result generation unit 11c determines whether or not a user who owns an IC card whose ticket information has been transmitted from the automatic ticket gate 5 can pass through the ticket gate passage, and also generates ticket information to be recorded on this IC card. . The processing result generation unit 11c generates a processing result including a determination result as to whether the vehicle is allowed to pass and ticket information to be recorded on the IC card. The usage history updating unit 11d additionally registers usage data related to the usage in the usage history DB 12 in accordance with usage of the IC card.

The control unit 11 of the determination server 1 is comprised of a hardware CPU, memory, and other electronic circuits. When the hardware CPU executes a processing program installed in advance, it operates as a fare calculation section 11a, an unprocessed determination section 11b, a processing result generation section 11c, and a usage history update section 11d. The memory also has an area for developing a processing program and an area for temporarily storing data generated during execution of this processing program. The control unit 11 may be an LSI integrated with a hardware CPU, memory, and the like.

FIG. 3 is a block diagram showing the configuration of the main parts of the automatic ticket gate. The automatic ticket gate 5 includes a control unit 51, an IC card R/W 52, a user detection section 53, a display section 54, a door opening/closing section 55, an unprocessed traffic information storage section 56, and a communication section 57. We are prepared.

The control unit 51 controls the operation of each part of the automatic ticket gate 5 main body. The control unit 51 of the automatic ticket gate 5 includes a communication state detection section 51a and a traffic control section 51b.

The communication state detection unit 51a detects whether or not there is a communication failure state in which communication cannot be performed with the determination server 1 via the network 3. In this example, the determination server 1 sends a read instruction command to each automatic ticket gate 5 connected via the network 3 at regular intervals ( For example, the data is repeatedly transmitted at intervals of several tens of milliseconds. The communication state detection unit 51a detects a poor communication state when the reading instruction command is interrupted for a period exceeding a threshold time (for example, several seconds). Furthermore, when the communication state detection unit 51a receives a read instruction command from the determination server 1 while detecting a poor communication state, it detects that the poor communication state has been resolved.

The traffic control unit 51b controls a door opening/closing unit 55, which will be described later, to restrict (permit or prohibit) the passage of users through the ticket gate passage.

The control unit 51 of the automatic ticket gate 5 includes a hardware CPU, memory, and other electronic circuits. When the hardware CPU executes the ticket inspection program according to the present invention, it operates as the communication state detection section 51a and the traffic control section 51b. The memory also has an area for developing the ticket inspection program and an area for temporarily storing data generated when the ticket inspection program is executed. The control unit 51 may be an LSI integrated with a hardware CPU, memory, and the like. Further, the hardware CPU is a computer that executes the ticket inspection method according to the present invention.

The IC card R/W 52 reads and writes ticket information to and from an IC card, which is a ticket medium. The IC card R/W 52 has a wireless communication area within several centimeters from the antenna, and the user reads and writes ticket information on the IC card through wireless communication with the IC card held within the wireless communication area. . The automatic ticket gate 5 is provided with an antenna so that the wireless communication area is near the entrance of the ticket gate passageway. Since IC cards used as tickets are well known, detailed explanation will be omitted here.

The user detection unit 53 detects the position of a user passing through the ticket gate passageway using a plurality of sensors arranged along the direction in which the user passes through the ticket gate passageway. The display unit 54 displays a message for the user who has entered the ticket gate passage. The door opening/closing section 55 opens and closes the door located on the exit side of users passing through the ticket gate passageway according to instructions from the traffic control section 51b.

The unprocessed traffic information storage unit 56 stores unprocessed traffic information including the identification code of the IC card read by the IC card R/W 52 when the communication state detection unit 51a detects a communication failure state. . The communication unit 57 controls communication with the determination server 1.

<3. Operation example>
The operation of the ticket gate system of the present invention will be explained below. FIG. 4 is a flowchart showing the operation of the automatic ticket gate. The automatic ticket gate 5 in this example operates in the normal mode when it can communicate with the determination server 1, and operates in the failure mode when it cannot communicate with the determination server 1.

The automatic ticket gate 5 starts operating in normal mode (s1). The automatic ticket gate 5 operates in the normal mode until the communication state detection unit 51a detects a communication failure state in which communication with the determination server 1 cannot be performed (s2). When the communication state detection unit 51a detects that the automatic ticket gate 5 is in a communication failure state in which communication with the determination server 1 cannot be performed, the automatic ticket gate 5 shifts from the normal mode to the failure mode (s3). The automatic ticket gate 5 operates in the fault occurrence mode until the communication state detection unit 51a detects that the poor communication state has been resolved (s4). In the failure mode, the automatic ticket gate 5 stores unprocessed traffic information including the identification code of the IC card read by the IC card R/W 52 in the unprocessed traffic information storage section 56. When the communication state detection unit 51a detects that the poor communication state has been resolved, the automatic ticket gate 5 transmits the unprocessed traffic information stored in the unprocessed traffic information storage unit 56 to the determination server 1 (s5). , the mode shifts from the failure mode to the normal mode (s1).

In this example, the communication state detection unit 51a detects a poor communication state when the read instruction command from the determination server 1 is interrupted for more than a threshold time (for example, several seconds). Furthermore, when the communication state detection unit 51a receives a read instruction command from the determination server 1 while detecting a poor communication state, it detects that the poor communication state has been resolved.

FIG. 5 is a flowchart showing the operation of the automatic ticket gate in normal mode. As described above, the determination server 1 sends a read instruction command to each automatic ticket gate 5 connected via the network 3 at regular intervals to instruct the automatic ticket gates 5 to read the ticket information recorded on the IC card. (for example, at intervals of several tens of milliseconds).

The automatic ticket gate 5 reads the IC card R/W 52 from the IC card located within the wireless communication area (the IC card held by the user within the wireless communication area) in accordance with the reading instruction command from the determination server 1. Repeatedly poll for a response. When the automatic ticket gate 5 reads the ticket information from the IC card held within the wireless communication area by the IC card R/W 52, it transmits the determination information including the currently read ticket information to the determination server 1 ( s11, s12). In s12, the ticket information read this time includes the date and time when the ticket information was read, the machine number that identifies the own machine (automatic ticket gate 5), the station where the own machine is installed, and the user's direction of travel (toward the station premises). The judgment information including information such as entry or exit from the station premises is sent to the judgment server 1. A communication unit 57 communicates with this determination server 1 .

The ticket information read from the IC card includes the identification code that identifies this IC card, the previous usage history (information indicating which station you entered or exited at last time), and the value balance held. , the section where the commuter pass is used, the expiration date of the commuter pass, etc. Further, information other than the identification code is encrypted. The identification code is not encrypted.

The automatic ticket gate 5 waits to receive the processing result from the determination server 1 (s13). The processing of the determination server 1 will be described later. The judgment server 1 generates a processing result including a judgment result as to whether the user can pass through the ticket gate passage, and information to be written on the IC card (date and time of current use, station used, type of entry/exit, value balance), The generated processing result is transmitted to the automatic ticket gate 5. The information written to the IC card is encrypted in the determination server 1.

The automatic ticket gate 5 writes the information to be written in the IC card received from the determination server 1 this time when the processing result received from the determination server 1 is that the user is permitted to pass through the ticket gate passageway. At the same time, the door located on the exit side of the ticket gate passageway for the user is opened (s14 to s16). The process related to s15 is performed by the IC card R/W 52. In s16, the traffic control unit 51b controls the door opening/closing unit 55 to open the door located on the exit side of the ticket gate passageway for the user.

Furthermore, if the processing result received from the determination server 1 does not allow the user to pass through the ticket gate passage, the automatic ticket gate 5 closes the door located on the exit side of the ticket gate passage for the user. (s14, s17). In s17, the traffic control section 51b controls the door opening/closing section 55 to close the door located on the exit side of the ticket passageway for the user.

Note that the process shown in FIG. 5 is a process for one user passing through the ticket gate passage, and the automatic ticket gate 5 can perform the process shown in FIG. 5 in parallel.

Next, the operation of the automatic ticket gate 5 in the failure mode will be explained. FIG. 6 is a flowchart showing the operation of the automatic ticket gate in the failure mode. The automatic ticket gate 5 repeatedly polls IC cards located within the wireless communication area (IC cards held up within the wireless communication area by the user) using the IC card R/W 52 to request a response. The automatic ticket gate 5 performs this polling independently in the failure mode. That is, in the failure mode, the automatic ticket gate 5 in this example responds to an IC card located within the wireless communication area using the IC card R/W 52 even if there is no read instruction command from the determination server 1. Repeated polling to request.

When the automatic ticket gate 5 reads the ticket information from the IC card held within the wireless communication area by the IC card R/W 52 by polling independently, the automatic ticket gate 5 reads the unprocessed ticket information including the identification code of the IC card read this time. The traffic information is stored in the unprocessed traffic information storage section 56 (s21, s22). The unprocessed traffic information is information that associates the identification code of the IC card read this time with the date and time of passage through the ticket gate (the date and time when the identification code was read), the station where the automatic ticket gate 5 is installed, the type of entry and exit, etc. .

When the automatic ticket gate 5 stores the unprocessed traffic information in the unprocessed traffic information storage unit 56 in s22, the traffic control unit 51b controls the door opening/closing unit 55 to open the door located on the exit side of the ticket passageway for the user. is opened (s23). That is, in the failure mode in which communication with the determination server 1 is interrupted, the automatic ticket gate 5 reads the identification code of the IC card owned by the user to prevent the user from passing through the ticket gate passage. Allow. Therefore, even if the judgment server 1 goes down due to a failure, or if a failure occurs in the network 3 used for communication between the judgment server 1 and the automatic ticket gate 5, the situation can be utilized. It is possible to allow people to pass through the ticket gate without noticing. As a result, when the judgment server 1 goes down due to a failure or a failure occurs in the network 3 used for communication between the judgment server 1 and the automatic ticket gate 5, the user's convenience is improved. Do not reduce sexuality.

Note that the process shown in FIG. 6 is a process for one user passing through the ticket gate passage, and the automatic ticket gate 5 can perform the process shown in FIG. 6 in parallel.

Next, the operation of the determination server 1 will be explained. The automatic ticket gate 5 in this example transmits the unprocessed traffic information to the determination server 1 in s5, as described above. When the communication unit 14 receives the unprocessed traffic information transmitted from the automatic ticket gate 5, the determination server 1 in this example stores the received unprocessed traffic information in the unprocessed traffic information storage section 13. FIG. 7 is a flowchart showing the operation of the determination server.

Note that the operation of the determination server 1 shown in FIG. 7 is an operation when communication with the automatic ticket gate 5 is not interrupted.

The determination server 1 waits for the communication unit 14 to receive the determination information transmitted from the automatic ticket gate 5 (s31). When the determination server 1 receives the determination information transmitted from the automatic ticket gate 5, the unprocessed determination unit 11b determines the unprocessed traffic information using the identification code of the IC card included in the currently received determination information. The unprocessed traffic information stored in the storage unit 13 is searched, and the presence or absence of the corresponding unprocessed traffic information is determined (s32).

If the unprocessed traffic information including the identification code of the IC card included in the currently received determination information is stored in the unprocessed traffic information storage unit 13, the unprocessed traffic determination unit 11b stores the unprocessed traffic information. is read out (s33). The number of unprocessed traffic information read in s33 is not necessarily one.

Note that, if the unprocessed traffic information including the identification code of the IC card included in the currently received determination information is not stored in the unprocessed traffic information storage unit 13, the unprocessed determination unit 11b performs s33. No processing is performed.

The fare calculation unit 11a determines whether a fare calculation is necessary to calculate the fare in the current process (s34). S34 is a process for determining whether or not there is a fare to be paid for the user. In addition, in s34, if the unprocessed traffic information has been read out in s33, the unprocessed traffic determination unit 11b determines whether or not fare calculation is necessary, including the unprocessed traffic information.

If the fare calculation unit 11a determines in s34 that fare calculation is necessary, it calculates the fare (s35). In s35, if the unprocessed traffic determination unit 11b has read the unprocessed traffic information in s33, fares may be calculated for a plurality of usage sections. If the fare calculation unit 11a determines in s34 that fare calculation is not necessary, it does not perform the process in s35.

The processing result generation unit 11c uses the determination information received in s31 and the fare amount calculated in s35 to determine whether the user is allowed to pass through the ticket gate (s36). When the processing result generation unit 11c determines that the user is permitted to pass through the ticket gate passage, it generates ticket information to be written in the user's IC card (s37). In s37, the generated ticket information is also encrypted. Furthermore, if the unprocessed traffic information is read out in s33 by the unprocessed determining unit 11b, the ticket information generated in s37 includes not only the ticket information related to the current use but also the unprocessed traffic information read out in s33. Ticket information corresponding to the information is also included. If the processing result generation unit 11c determines that the user is not allowed to pass through the ticket gate passage, it does not perform the processing related to s37.

The determination server 1 transmits the processing result generated by the processing result generation unit 11c to the automatic ticket gate 5 that has transmitted the determination information this time (s38). The processing results sent to the automatic ticket gate 5 in s38 include not only the determination result of whether the user can pass through the ticket gate passage, but also the ticket information generated in s37 (this ticket information is encrypted). )It is included. The automatic ticket gate 5, which has received the processing result transmitted by the determination server 1 in s38, executes the processing from s14 described above.

The determination server 1 updates the usage history of the corresponding IC card registered in the usage history DB 12 according to the ticket information included in the processing result sent to the automatic ticket gate 5 in s38 (s39), This process ends. Further, the judgment server 1 uses the unprocessed traffic information stored in the unprocessed traffic information storage unit 13, and in this process, registers it in the usage history DB 12 and checks the user's IC card at the automatic ticket gate 5. The unprocessed traffic information written on the card is deleted from the unprocessed traffic information storage section 13.

Note that the process shown in FIG. 7 is a process for the determination information transmitted about one user passing through the ticket gate passageway, and the determination server 1 can perform the process shown in FIG. 7 in parallel.

In this way, in the ticket gate system according to this example, when a failure occurs (when there is poor communication), the automatic ticket gate 5 allows the user to pass through the ticket gate passage simply by reading the identification code of the IC card. Also, the usage history of the IC card can be properly acquired and managed by the determination server 1.

<4. Modified example>
In the above example, it is assumed that the ticket information is stored in the IC card, but the present invention can be applied even to a system in which the ticket information is not stored in the IC card. In this case, the automatic ticket gate 5 transmits the identification code of the read IC card to the determination server 1, and the determination server 1 informs the automatic ticket gate 5 whether or not the user can pass through the ticket gate. All you have to do is send the determination result.

This ticket gate system can manage the usage history of the IC card in the usage history DB 12 of the determination server 1.

Further, the determination server 1 may have a configuration in which the usage history DB 12 is not provided. In this case, as explained in the above example, the IC card may be configured to store ticket information related to usage history.

Further, in the above example, the communication state detection unit 51a of the automatic ticket gate 5 detects whether there is a communication failure state based on the reception state of the reading instruction command from the determination server 1. The device 5 may periodically and repeatedly transmit a message to the determination server 1, and it may be detected whether there is a communication failure state based on the presence or absence of a response from the determination server 1 to this message. Further, the automatic ticket gate 5 may be configured to detect whether or not there is a communication failure through an input operation by an attendant or the like.

Furthermore, in the above example, the automatic ticket gate 5 does not store the composite key for decrypting the encrypted ticket information recorded on the IC card, but it does store the composite key. It is also possible to have a configuration in which
