Description

  The present invention relates to a gate device that restricts the passage of a user in a passage.

  Conventionally, at a ticket gate of a railroad station, a ticket gate process is performed by an automatic ticket gate for users who enter the station or users who enter from the station. The automatic ticket gate accepts tickets such as tickets, commuter passes, prepaid tickets, etc. possessed by the user, reads the ticket information recorded on this ticket, and based on the read ticket information, It is determined whether or not the ticket gate passage is accessible to the user. If the automatic ticket gate determines that the user is allowed to pass through the ticket gate, it opens the door located on the exit side of the ticket gate, and conversely determines that the user is not permitted to pass through the ticket gate. Then, the door located on the exit side of the ticket gate is closed.

In addition, there are illegal passers who intentionally break through the ticket gate passage by entering the ticket gate passage and jumping over the closed door without having a proper ticket. In order to suppress such illegal activities of passers-by, a camera that captures the users who pass through the ticket gates is installed, and if an illegal passer who deliberately breaks through the ticket gates is detected, the camera at that time It has been proposed to record and store the captured images (see Patent Documents 1 and 2, etc.).
Japanese Patent No. 3617127 Japanese Patent No. 3389029

  However, conventional automatic ticket gates have a plurality of sensors that detect the presence or absence of users along the ticket gates, and the output of these sensors tracks the position of the user passing through the ticket gates. Yes. Further, while one sensor continues to detect a user, it is determined that one user is passing through the detection area of this sensor. For this reason, in the conventional automatic ticket gate, when a plurality of users pass through the ticket gate passage, the plurality of users may be determined as one user. Therefore, when a plurality of users pass through the ticket gates, the plurality of users can pass through the ticket gates illegally with a single ticket. In other words, it has been impossible to detect an illegal act in which a plurality of users pass through the ticket gates and to prohibit these users from passing through the ticket gates.

Hereinafter, an illegal act in which a plurality of users pass through the ticket gates is referred to as overlapping traffic.

  In addition, as described above, since the automatic ticket gate determines a plurality of users performing overlapping traffic as one user, it can detect that overlapping traffic is being performed itself. Can not. For this reason, even if a camera that images a user passing through a ticket gate is installed like the automatic ticket gate proposed in Patent Documents 1 and 2, a plurality of users who are passing in an overlapping manner The captured images could not be recorded and saved. Therefore, even with the automatic ticket gates proposed in Patent Documents 1 and 2, it is not possible to obtain an effect of suppressing unauthorized passers who perform overlapping traffic.

  In addition, not only when improper traffic is detected, but if it is configured to always record and save the captured image of the camera, it is possible to record and save the captured image when overlapping traffic is performed, Check the recorded and saved captured image, and if there is a captured image when this overlapping traffic is performed, the operation must be performed to save the captured image of that portion as the captured image when the overlapping traffic is performed. It is very time-consuming and unrealistic.

  An object of the present invention is to provide a gate device capable of accurately detecting a fraudulent act in which a plurality of users pass through a passage with one pass ticket and prevent such a fraudulent act from being performed. It is to provide.

  In order to solve the above-described problems and achieve the object, the gate device of the present invention has the following configuration.

  In this gate device, the ticket information reading means accepts a passing ticket possessed by a user who has entered the passage, and reads the ticket information recorded in the passing ticket. Further, the determining means determines whether or not the user can pass the passage based on the ticket information read by the ticket information reading means. And a traffic restriction means restricts a user's traffic in the said passage according to the determination result of the said determination means.

  In addition, the number-of-people detecting means processes a captured image obtained by capturing the user passing through the passage, and detects the number of users captured in the captured image. For example, the number-of-people detecting means extracts the faces of each user imaged in the captured image, and detects the total number of the extracted faces as the number of users. Then, the number determination means determines whether the number of users detected by the number detection means is appropriate. The number determination means may determine the number of users in the passage based on, for example, the number of pass tickets read by the ticket information reading means. Therefore, even if a plurality of users who are passing through the passage are determined as a single user, the number of the plurality of users can be accurately detected by the number detection means. For this reason, it is determined by the number determination means that the number of users detected by the number detection means is not appropriate as the number of users in the passage. The passage restriction unit restricts the passage of the user in the passage regardless of the determination result of the passage permission determination unit when the number determination unit determines that the number of users in the passage is inappropriate. .

  Therefore, it is possible to accurately detect a fraudulent act in which a plurality of users pass through a passage with a single pass ticket and prevent such a fraudulent act from being performed.

  According to the present invention, it is possible to accurately detect a fraudulent act in which a plurality of users pass through a passage with a single pass ticket, and to prevent such a fraudulent act from being performed.

  Hereinafter, an automatic ticket gate as an embodiment of the present invention will be described.

  FIG. 1 is a diagram showing a configuration of a main part of an automatic ticket checker according to an embodiment of the present invention, and FIG. 2 is a schematic diagram showing an appearance of the automatic ticket checker. This automatic ticket gate 1 is installed at the ticket gate of a station, and a user who does not have an appropriate ticket (such as a ticket or commuter pass) passes through the ticket gate and enters the station, Limit participation from The automatic ticket gate 1 includes a control unit 2, a ticket processing unit 3, a user detection unit 4, a display unit 5, a door opening / closing unit 6, a notification unit 7, a captured image processing unit 8, and a camera. 9.

  The control unit 2 controls the operation of each part of the automatic ticket gate 1 main body. The ticket processing unit 3 receives a ticket held by a user who passes through the ticket gate, and reads and writes the ticket information recorded on the received ticket. The ticket includes a magnetic ticket that records the ticket information as magnetic data, a non-contact IC card that has a wireless communication function and records the ticket information in a built-in memory, and the like. The ticket processing unit 3 has a magnetic head that reads and writes the ticket information recorded on the magnetic ticket, and has a wireless communication unit that performs wireless communication with a non-contact IC card. Yes. Since these configurations are known, a description thereof is omitted here. A boarding ticket is equivalent to the pass ticket said by this invention, and boarding ticket information is equivalent to the ticket information said by this invention.

  The user detection unit 4 detects the position of the user in the ticket gate passage by detecting the presence or absence of the user with a plurality of sensors provided along the ticket gate passage. In addition, it is possible to track the users who are passing through the ticket gate by using the outputs of these sensors. The display unit 5 displays a guidance message or the like for a user traveling through the ticket gate passage on a display 5a provided near the exit side of the ticket gate passage. Moreover, the door opening / closing part 6 restricts the passage of the user in the ticket gate passage by opening and closing the door 6a provided near the exit side of the ticket gate passage. If the user who has entered the ticket gate does not have an appropriate boarding ticket, the notification unit 7 notifies that fact. Since the user detection unit 4, the display unit 5, the door opening / closing unit 6, and the notification unit 7 are known, detailed description thereof is omitted here.

  Furthermore, the captured image processing unit 8 processes the captured image of the user captured by the camera 9 and detects the number of users being captured. The camera 9 is attached to the entrance side of the ticket gate passage at a position where the user passing through the ticket gate passage is imaged from a slightly oblique direction from the front. As a result, even if another user sticks behind a certain user and passes through the ticket gate, the faces of the two users can be imaged. In other words, the camera 9 is attached so that the previous user is not in the shadow and the face of another user attached to the previous user is not captured. The camera 9 may be built in the main body of the automatic ticket gate 1 or may be attached to the ceiling or the like of the place where the automatic ticket gate 1 is installed. FIG. 2 illustrates a case where the camera 9 is attached to the main body of the automatic ticket gate 1 so as to face the entrance side of the ticket gate passage. The captured image processing unit 8 extracts the face of each captured user from the captured image of the camera 9, and detects the number of extracted faces as the number of captured users. The captured image processing unit 8 extracts the face of the user being captured from the captured image of the camera 9 by known pattern matching or the like.

  This automatic ticket checker 1 accurately detects a fraudulent act (hereinafter, this fraudulent act is referred to as overlapping traffic) where a plurality of users stick together and pass through the ticket gate passage with a single ticket. Prohibits users from passing through the ticket gates. Hereinafter, the operation of the automatic ticket gate 1 will be described in detail.

  FIG. 3 is a flowchart showing the operation of the automatic ticket gate. The automatic ticket gate 1 performs the processing shown in FIG. 3 for each user who enters the ticket gate. The automatic ticket gate 1 confirms that the user has reached the no-ticket detection position set by the user detection unit 4 on the entrance side of the ticket gate, whether the ticket processing unit 3 accepts the user's ticket (s1). Waiting for detection (s2). When the automatic ticket checker 1 accepts the ticket in s1, the ticket checker records the ticket information recorded in the ticket (s3). Based on the ticket information read in s3, the automatic ticket gate 1 determines whether or not the ticket gate passage for the user is allowed to pass (s4). In s4, based on the valid period and valid section of the ticket indicated by the ticket information read in s3, it is determined whether or not the ticket gate passage for the user is allowed. The determination as to whether or not the s4 can pass is based on whether or not the boarding ticket is appropriate.

  If the automatic ticket checker 1 determines that the passage is permitted in s4, it waits for the user to reach the no-tag detection position (s5). The no-ticket detection position is a position slightly inside the ticket gate passage, rather than a position where the user who passes through the ticket gate passage reads the ticket information of the ticket to the ticket processing unit 3. The position of the user in the ticket gate is detected by the user detection unit 4. In the automatic ticket gate 1, when the user who has determined that the passage is permitted in s4 reaches the no-tag detection position, the image processing unit 8 captures the image captured by the camera 9 (s6), and determines the number of users who are captured. Detect (s7). In s7, the user's face imaged in the captured image of the camera 9 is extracted, and the extracted face is detected as the number of users at the no-tag detection position.

  If the number of users detected in s7 is one, the automatic ticket checker 1 opens the door 6a (s8, s9), and permits the user to pass through the ticket check passage. On the other hand, if the number of users detected in s7 is two or more, it is determined that the traffic is overlapped, and the door 6a is closed (s8, s10). Moreover, the automatic ticket gate 1 performs warning alerting | reporting in the alerting | reporting part 7 (s11).

  Note that the automatic ticket gate 1 closes the door 6a at s10 when it is determined in s4 that passage of the ticket gate is not permitted, or when a user who has not accepted a ticket at s2 reaches the no-ticket detection position. At the same time, the notification unit 7 issues an alarm notification in s11.

  In this way, the automatic ticket gate 1 processes the captured image of the camera 9 and detects the number of users who have reached the no-card detection position, so that it can accurately detect the user who is passing through. be able to. Therefore, the automatic ticket gate 1 can prohibit the passage of the ticket gate passage for the user who is traveling in an overlapping manner.

  In the above example, it is determined whether or not overlapping traffic is performed based on whether or not one user is detected from the image captured by the camera 9 in s8. You may make it determine whether the overlapping traffic is performed using the number of tickets. Specifically, whether or not the number of users detected in s7 is equal to the number of users who have received a ticket that has not yet reached the no-tag position at this point It may be replaced with the process of determining. In this way, even if an appropriate ticket is received from two users, the two users are mistakenly identified as users who are overlapping and passing at the no-card detection position. Can be prevented.

  In addition, a captured image of the camera 9 when a user who has overlapped traffic is detected may be recorded and saved.

  In the above description, the present invention is applied to an automatic ticket gate 1 installed at a ticket gate of a station. However, the present invention is a gate installed at an entrance of a facility such as an amusement park or a theme park. It can also be applied to devices.

It is a figure which shows the structure of the principal part of an automatic ticket gate. It is the schematic which shows the external appearance of an automatic ticket gate. It is a flowchart which shows operation | movement of an automatic ticket gate.
