Description

An embodiment of the present invention relates to a ticket gate and a ticket gate processing program.

Conventionally, ticket gates installed at railway stations and the like determine whether or not a user can enter or exit (pass) based on the information written on the ticket presented by the user during the entry or exit process. When determining whether or not a user can pass, the ticket gate determines whether or not a user can pass based on the validity zone and expiration date, etc., identified from the information recorded on the ticket, and also determines whether or not a user can pass based on whether or not the entry/exit cycle recorded on the ticket is normal. In other words, conventional ticket gates determine that a user cannot pass if they enter or exit repeatedly.

Furthermore, conventional ticket gates use IC cards with contactless communication or portable electronic devices such as mobile terminals as tickets. For example, a ticket gate determines whether or not a contactless IC card can pass based on information read by contactless communication from a contactless IC card held up at a specified reading position. Ticket gates also determine whether or not a contactless IC card can pass by checking the entry/exit cycle. For this reason, if an IC card that has already been processed as passable is held up again immediately afterwards, the ticket gate will process the IC card as not allowing passage.

However, in actual operation, a user may hold up an IC card again without realizing that the IC card has already been processed as passable during a single entry or exit. In such cases, conventional ticket gates will uniformly process the user who holds up the IC card again as not being able to pass through, which creates the problem that the user must be assisted by an attendant to pass through the ticket gate.

In order to solve the above problems, the present invention aims to provide a ticket gate and a ticket gate processing program that can prevent fraudulent use while allowing the re-presentation of a ticket medium.

According to an embodiment, the ticket gate has a memory, a ticket processing unit, and a processor. The memory holds information. The ticket processing unit reads information from the ticket medium presented by the user. If the information read from the ticket medium by the ticket processing unit indicates passage, the processor stores processed ticket information in memory, including information about the ticket that has been permitted, and if the information read from the ticket medium by the ticket processing unit indicates non-passage, the processor allows the user to pass if the information read from the ticket medium matches the processed ticket information stored in the memory.

Hereinafter, embodiments will be described with reference to the drawings.
FIG. 1 is a diagram showing an outline of the overall configuration of a ticket gate system 1 according to an embodiment of the present invention.
The ticket gate system 1 is a system that connects ticket gates 13 installed at the ticket gates of each station. In the configuration example shown in Fig. 1, the ticket gate system 1 includes a server 11, a monitoring panel 12, and ticket gates 13. For example, the server 11 is connected to the monitoring panel 12 installed for each monitored object such as a ticket gate or a station. A plurality of ticket gates 13 installed at the ticket gates of each station are connected to the monitoring panel 12 of each station.

The server 11 is connected to the monitoring panel 12 via a network. The server 11 supplies the monitoring panel 12 with information to be provided to each ticket gate 13. The server 11 may also obtain, via the monitoring panel 12, information indicating the operating status of each ticket gate 13 and information indicating the results of the ticket gate processing at each ticket gate 13.

The monitoring panel 12 is connected to the server 11 and to multiple ticket gates 13. The monitoring panel 12 is connected, for example, to a ticket gate 13 installed at the ticket gate to be monitored. The monitoring panel 12 monitors the operating status of each connected ticket gate 13 and remotely supplies operating instructions to each ticket gate 13. The monitoring panel 12 also has the function of distributing information supplied from the server 11 to each ticket gate 13.

Each ticket gate 13 is installed at the ticket gate of each station and performs ticket gate processing (entry processing and exit processing) at the ticket gate. The server 11, the monitoring panel 12, and the ticket gate 13 constitute a ticket gate system that realizes ticket gate processing at ticket gates at stations and the like. The ticket gate 13 switches operating modes in response to instructions from the monitoring panel 12, and performs ticket gate processing using information from the monitoring panel 12.

In the following description, the ticket gate 13 according to this embodiment performs ticket gate processing based on a contactless IC card held by the user as the ticket medium. However, the ticket medium that the ticket gate 13 processes as a ticket may be any medium that records information that can be read by the ticket gate 13.

For example, the ticket medium may be a magnetic recording medium (magnetic ticket) in which information is recorded in a magnetic recording section, a recording medium (code ticket) in which coded information such as a two-dimensional code is recorded (printed or displayed), a contactless IC card that transmits and receives information via contactless communication, a mobile terminal such as a mobile phone that has the same functions as a contactless IC card, or a mobile terminal that displays coded information such as a two-dimensional code.

Next, the configuration of the ticket gate 13 according to the embodiment will be described.
FIG. 2 is a side view that illustrates a schematic configuration example of the ticket gate 13 according to the embodiment.
For example, two ticket gates 13 form one ticket gate (entrance or exit) passage in a set. The ticket gates 13 may be used as dedicated entry or exit gates that can pass through the ticket gate passage in only one direction, or as dual-purpose gates that can pass through the ticket gate passage in both directions. The ticket gates 13 are set in advance as either dedicated entry gates, dedicated exit gates, or dual-purpose gates.

In the configuration example shown in FIG. 2, the ticket gate 13 has a housing 30 that forms an entrance or exit passage. The housing that forms the ticket gate 13 is provided with a ticket processing unit (passenger ticket processing unit) 32 that performs ticket processing such as reading information from a ticket held by a user. A reading unit (communication unit) of the ticket processing unit 32, through which the user presents the ticket, is provided at one end (the end on the entrance side) of the top surface of the housing 30 that forms the ticket gate 13. The ticket processing unit 32 reads information recorded on an IC card that the user presents to the reading unit as a ticket.

For example, the ticket processing unit 32 includes a card reader/writer that reads information from an IC card that the user presents as a ticket at a specified reading unit. Note that the ticket processing unit 32 may also be equipped with a device that processes media other than IC cards used as tickets. For example, the ticket processing unit 32 may be configured to include a magnetic ticket processing unit that processes magnetic tickets that have ticket information recorded in a magnetic recording unit. Also, the ticket processing unit 32 may be configured to include a code reader that reads code information from a medium on which code information as ticket information is printed.

A display unit 33 for providing guidance to users or staff is provided on the top surface of the housing forming the ticket gate 13. The display unit 33 is, for example, configured with a liquid crystal display device. The display unit 33 displays a guidance screen that informs users passing through the passage of the results of the ticket gate processing. The display unit 33 may be provided in a position where the user can confirm the displayed content. The display unit 33 is not limited to being set at the end of the top surface of the housing on the exit side, and may be provided, for example, in the center of the top surface of the housing or adjacent to the reading unit of the ticket processing unit 32 on the top surface of the housing.

At both ends of the side of the case 30 that forms the ticket gate 13 facing the passageway, there are provided doors 34, 35 that can be opened and closed to allow or deny passage of pedestrians. In the configuration example shown in FIG. 2, if the direction of arrow a is the direction of travel toward the exit, door 34 is provided at the end of the passageway on the exit (entrance) side and prevents users from passing through the passageway. Door 35 is provided at the end of the passageway on the entrance (entrance) side and prevents users from entering the passageway.

A number of detection sensors (human detection sensors) 36 are provided inside a sensor cover on the top surface of the housing 30 that forms the ticket gate 13 and on the side of the housing 30. The detection sensors 36 are composed of reflective detection sensors or transmissive detection sensors. The output signal from the detection sensors 36 is either "light" or "dark." The detection sensors 36 detect whether or not a person is present at a specified detection position. The ticket gate 13 uses the multiple detection sensors 36 to detect the presence or absence of a person at each detection position in the passage. As a result, the ticket gate 13 is able to determine the position of a user passing through the passage based on the detection results of the multiple detection sensors 36.

Furthermore, the ticket gate 13 is provided with a proximity sensor 37 on the side facing the passage entrance direction on the side where the reading unit of the ticket processing unit 32 is provided (the entrance side of the passage). The proximity sensor 37 detects a person approaching the ticket gate 13. The ticket gate 13 detects a person approaching the passage using the proximity sensor 37, allowing the person to smoothly undergo ticket gate processing. For example, the proximity sensor 37 may detect a person in a position where they can present an IC card as a boarding ticket to the reading unit of the ticket processing unit 32. In this case, the ticket gate 13 may control the ticket processing unit 32 to become operable according to the detection result of the proximity sensor 37.

In addition, when the passageway is operated in both directions, the ticket gate 13 controls the direction of travel of the user (ticket gate direction) by controlling the opening and closing of the door 35 in response to the detection result of the approach sensor 37. In addition, the ticket gate 13 may be configured to control switching between a power saving mode, which reduces power consumption by turning off the display unit 33, and a normal operation mode (operation mode in which ticket gate processing is performed), in response to the detection result of the approach sensor 37.

The ticket gate 13 may also be provided with a passage guidance display unit on the side facing the passage entrance direction on the side where the reading unit of the ticket processing unit 32 is provided (the entrance side of the passage). For example, the ticket gate 13 may display on the passage guidance display unit whether or not entry to the passage to the ticket gate is possible.

Next, the configuration of the ticket gate 13 according to this embodiment will be described.
FIG. 3 is a block diagram showing an example of the configuration of a control system in the ticket gate 13 according to this embodiment.
In the example configuration shown in Figure 3, the ticket gate 13 has a processor 41, a ROM 42, a RAM 43, a memory unit 44, a communication unit 45, a clock 46, a door control unit 47, a ticket processing unit 32, a display unit 33, a detection sensor 36, and a proximity sensor 37.

The processor 41, ROM 42, and RAM 43 function as a control unit that controls the entire ticket gate 13. The processor 41 is, for example, a calculation unit such as a CPU. The processor 41 realizes various processing functions by executing programs stored in the ROM 42 or the memory unit 44. For example, the processor 41 executes a ticket gate processing program stored in the ROM 42 or the memory unit 44 for performing the ticket gate processing described below.

The ROM 42 is a non-volatile memory. The ROM 42 functions as a program memory that stores programs executed by the processor 41. The ROM 42 stores programs executed by the processor 41, control data, etc.

RAM 43 is a memory that temporarily stores data. RAM 43 functions as a working memory. RAM 43 loads programs and stores data being processed by processor 41. RAM 43 also functions as a buffer memory that temporarily stores communication data, etc.

The storage unit 44 is a memory that stores data. The storage unit 44 includes a rewritable non-volatile memory such as an HDD or SSD. The storage unit 44 stores information such as fare information used in ticket gate processing. The storage unit 44 may also store programs executed by the processor 41, control information, etc.

The communication unit 45 is a communication interface for communicating with the monitoring panel 12. The communication unit 45 may be an interface for wired communication with the monitoring panel 12, or an interface for wireless communication. The communication unit 45 transmits information indicating the operating status to the monitoring panel 12, and receives control instructions such as the operating mode from the monitoring panel 12.

The clock 46 measures time. The processor 41 obtains the elapsed time based on the time measured by the clock 46. The clock 46 may be a timer that measures the elapsed time from a time instructed by the processor 41.

The ticket processing unit 32 processes the ticket medium presented by the user. In this embodiment, the ticket processing unit 32 is configured with a card reader/writer that performs contactless communication with a contactless IC card (or a mobile terminal device with the same function as a contactless IC card) as the ticket medium. The ticket processing unit 32 may also include a mechanism for processing a magnetic ticket as the ticket medium.

The ticket processing unit 32 communicates with a contactless IC card, which serves as a ticket medium, held over the reading unit (predetermined reading range), and acquires information recorded on the IC card. When allowing a user who has held an IC card over the reading unit to pass, the ticket processing unit 32 writes information indicating the results of ticket gate processing, etc., to the held IC card.

The display unit 33 is a display that displays guidance to users passing through the ticket gate. The display unit 33 is installed, for example, near the exit side or near the center of the main body of the ticket gate 13 so that it is easy for users passing through the ticket gate to see. The display content, such as guidance, displayed on the display unit 33 is controlled by the processor 41.

The door control unit 47 includes a door opening/closing mechanism that opens and closes the doors 34 and 35. The door control unit 47 controls the passage of users by opening and closing the doors 34 and 35. For example, the door control unit 47 closes the door 34 to prevent passage through the passage that the ticket gate 13 forms at the ticket gate.

The detection sensor 36 is a sensor that detects the presence or absence of a person (object). As shown in FIG. 2, the detection sensor 36 is installed on the side of the ticket gate 13 so that each position in the passage is a detection position, and outputs a detection signal indicating the presence or absence of a person at each position to the processor 41. The processor 41 can detect the position of a person in the passage and whether or not a person is passing through the passage based on the detection result of the detection sensor (human detection sensor) 36.

The approach sensor 37 detects a person approaching the ticket gate 13. The approach sensor 37 is provided on the entrance side of the housing of the ticket gate 13, and outputs a detection signal to the processor 41 indicating the presence or absence of a person near the entrance of the ticket gate 13.

Next, a summary of the process performed by the ticket gate 13 in the ticket gate system 1 according to the embodiment will be given.
The ticket gate 13 according to this embodiment controls whether or not a user can pass depending not only on the validity of the ticket, such as the validity zone and validity period, but also on the entry/exit status (entry/exit cycle). Furthermore, the ticket gate 13 according to this embodiment allows the user to pass even if the user holds up the same IC card twice, as long as certain conditions are met.

For example, when the ticket gate 13 according to this embodiment allows a certain IC card to pass, it allows the IC card to be held up again within a specified re-presentation time, and allows the user to pass. To achieve this type of operation, the ticket gate 13 stores information about IC cards that have been determined to be passable, and if an IC card that has been processed as passable is presented again within the specified re-presentation time, it allows the user who presented the IC card to pass.

FIG. 4 is a diagram showing an example of information related to an IC card that has been processed as passable and is held by the ticket gate 13 according to the embodiment.
When the processor 41 of the ticket gate 13 processes the IC card presented by the user as passable, it stores information about the IC card as shown in Fig. 4 in the RAM 43. In the example shown in Fig. 4, the card number, the processing time, and written information are stored in the RAM 43 as information about the IC card that has been processed as passable (processed card information).

The card number is information for identifying an IC card that has been processed as passable. The card number may be any unique information that can be read from the IC card.
The processing time is information indicating the time when the IC card was processed as passable. The processing time may be the time when information was read from the IC card, or the time when write information was written to the IC card. Furthermore, instead of the processing time, the processed card information may be updated and stored as needed to indicate the elapsed time since the IC card was processed as passable.

The written information is information (written encoding) written to an IC card that has been processed as passable. The ticket gate 13 writes encoded information indicating the processing result, including entry/exit information indicating whether the card is in an entry or exit state, to an IC card that has been processed as passable. Therefore, the written information stores the encoded information written to the IC card as processed card information.

Next, a ticket inspection process (passage control process) performed by the ticket inspector 13 according to the embodiment based on an IC card presented by a user will be described.
FIG. 5 is a flowchart for explaining the ticket examination process performed by the ticket examiner 13 according to the embodiment for an IC card presented by a user.
During standby, the processor 41 of the ticket gate 13 monitors the detection results of the approach sensor 37 and the detection sensor 36. The processor 41 detects the entrance of a user into the passageway based on the detection results of the approach sensor 37 and the detection sensor 36.

When processor 41 detects a user entering the passageway, it operates ticket processing unit 32 to make the IC card that the user holds over the reading unit readable. When a user in the passageway holds (presents) an IC card over the reading unit, ticket processing unit 32 reads the information recorded on the IC card held over the reading unit. Ticket processing unit 32 supplies the information read from the IC card held over the reading unit to processor 41. Processor 41 acquires the information that ticket processing unit 32 reads from the IC card held over the reading unit (ST11).

When the ticket processing unit 32 acquires information read from the IC card held up to the reading unit, the processor 41 executes a passage judgment to judge whether the user is permitted to pass based on the information read from the IC card (ST12). The processor 41 judges whether the user is permitted to pass based on the validity of the ticket based on ticket information such as the validity zone and expiration date specified from the information read from the IC card, and also judges whether the user is permitted to pass based on the entry/exit status (entry/exit cycle judgment) indicated by the entry/exit information read from the IC card.

That is, processor 41 determines whether the user is allowed to pass based on the validity of the ticket and the entry/exit status. To determine the entry/exit cycle, processor 41 determines whether the entry/exit information is normal based on whether entries or exits are consecutive. For example, if the entry/exit information read from an IC card held up to the reading section by a user passing in the direction of entry indicates an entry state, processor 41 determines that the entry/exit cycle is abnormal (passage is prohibited) because entries are consecutive. Also, processor 41 determines that the entry/exit cycle is normal if the entry/exit information read from an IC card held up to the reading section by a user passing in the direction of entry indicates an exit state.

When it is determined that the user is permitted to pass based on the information read from the IC card (ST13, YES), processor 41 generates write information to be written to the IC card that has been permitted to pass, and writes encoded write information that encodes the generated write information to the IC card (ST14). For example, when processor 41 allows a user to enter, it writes information that sets the entry/exit information to an entry state to the IC card by ticket processing unit 32, in addition to information such as the entry station and date and time. When processor 41 allows a user to exit, it writes information that sets the entry/exit information to an exit state to the IC card by ticket processing unit 32, in addition to information such as the exit station and date and time.

When the write information is written to the IC card determined to be passable, the processor 41 stores the card number (identification information), processing time, and write information (write encoding information) of the IC card determined to be passable in the RAM 43 (or the memory unit 44) as processed card information (ST15). The processed card information is information about the IC card that was presented by a user in the passage and processed as passable. Furthermore, if the operation assumes that a user will hold up their IC card multiple times in succession, the processed card information may be information about the IC card that was previously processed as passable.

After storing the processed card information, the processor 41 allows the user who presented the IC card to pass and executes a process to prompt the user to pass (ST16). For example, the processor 41 allows the user to pass by opening the exit door 34 via the door control unit 47 and displaying a message on the display unit 33 indicating that the user is allowed to pass.

In addition, when the user is permitted to pass, the processor 41 monitors the user's position using the detection sensor 36 until the user passes through the passage (exits through the exit), and measures the time that has elapsed since the user was permitted to pass (determined to be permitted to pass) while remaining in the passage.

When it is detected that the user has passed through the passage (exited through the exit) (ST17, YES), the processor 41 clears the processed card information relating to the card presented by the user from the RAM 43 (ST24).

If the user remains in the passage (ST17, NO), the processor 41 determines whether the time that has elapsed since the user was permitted to pass has exceeded the predetermined re-presentation time (ST18). If the time that has elapsed since the user was permitted to pass while remaining in the passage has exceeded the predetermined re-presentation time (ST18, YES), the processor 41 clears the processed card information relating to the card presented by the user from the RAM 43 (ST24).

As a result, the ticket gate 13 can deny passage to a user who has remained in the passageway for a long time exceeding the specified re-presentation time and who then re-presents an IC card that has been processed as permitted to pass. By changing the re-presentation time in relation to the elapsed time, the ticket gate 13 can set the time during which an IC card that has been processed as permitted to pass can be presented again (re-presented).

If the time that the user remains in the passage is within the specified re-presentation time (ST18, NO), the processor 41 accepts the presentation of the IC card by the user while retaining the processed card information in the RAM 43. If the processor 41 detects that the IC card has been held over the reading section within the specified re-presentation time that has elapsed since passage was permitted (ST19, YES), the processor 41 returns to ST11 while retaining the processed card information, reads the IC card, and executes the above-mentioned process.

If an IC card that has been processed as permitted to pass is presented again to the reader of the ticket gate 13, the IC card presented again will be judged to have an abnormal entry/exit information, since it will result in continuous entry or exit. In other words, if an IC card is read again while still holding the processed card information, the processor 41 will determine that passage is not permitted based on the entry/exit cycle judgment in the passage judgment of ST12.

If it is determined that the IC card held over the reading section is not passable (ST13, NO), the processor 41 determines whether the card number of the read IC card (held IC card) matches the card number in the processed card information (ST20). If the card number of the read IC card matches the card number in the processed card information, the processor 41 can identify that the IC card is an IC card that was held over again after being processed as passable.

If the card number of the read IC card does not match the card number in the processed card information (ST20, NO), processor 41 denies the user who presented the IC card passage in accordance with the result of the passage judgment that determined passage to be denial (ST23). If the card number of the read IC card differs from the card number in the processed card information, it can be determined that the read IC card is not an IC card that was held up again after the passage judgment. Therefore, when the card numbers differ, processor 41 can prevent fraudulent use by denying the user passage based on the passage judgment result using the information stored in the IC card.

In addition, if the card number of the read IC card matches the card number in the processed card information (ST20, YES), the processor 41 further determines whether the written information in the processed card information with the matching card number matches the read information read from the IC card held over the reading unit (ST21).

If the written information in the processed card information does not match the read information read from the IC card (ST21, NO), processor 41 will not allow the user who presented the IC card to pass through (ST23). If the information written on the IC card when it is held up again differs from the written information in the processed card information, it is possible that other information was illegally written to the IC card before it was held up again, or that a processing error occurred. For this reason, when the written information in the processed card information does not match the read information read from the IC card, processor 41 will not allow the user who presented the IC card to pass through and will prompt an attendant to take action, thereby preventing illegal use, etc.

If the written information in the processed card information matches the read information read from the IC card held over the reading section (ST21, YES), the processor 41 calculates the elapsed time (the time until the IC card is held over again) from the processing time in the processed card information in which the card number and written information match and the current time measured by the clock 46, and determines whether the elapsed time is within the specified re-presentation time (ST22).

If the elapsed time exceeds the specified re-presentation time (ST22, NO), the processor 41 will not allow the user who presented the IC card to pass through (ST23). Since it is expected that a user will unintentionally hold up their IC card multiple times in a short period of time, by not allowing the user to pass through if the same IC card is held up again after the specified re-presentation time has elapsed, it is possible to prevent fraudulent use, etc.

If the elapsed time is within the specified re-presentation time (ST22, NO), that is, if an IC card with the same card number and matching written information is held up again within the specified re-presentation time, the processor 41 proceeds to ST15 and allows the passage of the user who held up the IC card (held it up again) over the reading section.

As described above, when the ticket gate according to the embodiment processes an IC card presented by a user as passable, it stores information about the IC card in a memory such as a RAM as processed card information. When the ticket gate determines that the IC card presented by a user is not passable, if the information about the IC card matches the processed card information about the IC card processed immediately before, it allows the user who presented the IC card to pass.

As a result, even if a user accidentally holds up the same IC card multiple times, if the information on the IC card matches the processed card information, the user can be allowed to pass through. As a result, it is possible to provide a ticket gate that is less stressful for users, while still preventing fraudulent use by checking the information recorded on the IC card and allowing the user to pass through even if they hold up their IC card again.

In addition, when the ticket gate according to the embodiment determines that the IC card presented by the user is not allowed to pass, if the card number of the IC card matches the card number contained in the processed card information relating to the most recently processed IC card, the ticket gate allows the user who presented the IC card to pass.

This makes it possible to reliably check whether a user has held up the same IC card multiple times, providing a ticket gate that can implement passage control that allows users to hold up their IC card again unintentionally.

Furthermore, when the ticket gate of the embodiment determines that the IC card presented by a user is not to be passed through, if the information on the IC card matches the processed card information and the time that has elapsed since the processing time indicated by the processed card information is within a specified re-presentation time, the ticket gate will allow the user who presented the IC card to pass through.
This makes it possible to provide a ticket gate that can realize passage control that allows a user to hold up the same IC card multiple times within a specified re-presentation time.
