Description

  The present invention relates to a gate device that controls passage of a passerby.

  2. Description of the Related Art Conventionally, a gate device that uses a magnetic ticket or a non-contact IC card (RFID tag) as a passing ticket and controls passage of a passage according to the presence or absence of the passing ticket has been widely used. Examples of such a gate device include an automatic ticket gate installed at a ticket gate of a station and a security gate installed at an entrance of a company or the like. When a passer-by passes through the passage where the gate device is installed, a magnetic ticket is inserted into the insertion port installed on the entrance side of the gate device, or the contactless IC is connected to the antenna installed on the entrance side of the gate device. An operation of actively presenting and reading a pass ticket to the gate device, such as holding a card, is necessary. Hereinafter, a pass ticket that needs to be presented to the gate device, such as a magnetic ticket or a non-contact IC card, is also referred to as a presentation medium.

  Recently, there has been proposed a gate device that does not require a passerby to actively present a pass ticket (see Patent Document 1). In this gate device, an electrode is installed in a passage, and a human body of a passer-by who has a human body communication medium (user device) as a pass ticket functions as a dielectric of a capacitor that connects between the human body communication medium and the electrode. . That is, the gate device performs human body communication between the electrode and the human body communication medium via the human body of the passerby. Passers pass through the electrodes when passing through the passage where the gate device is installed, so they can read the information on the pass ticket to the gate device even if they have a human body communication medium and do not actively present it. Can be made. Hereinafter, a pass ticket that does not need to be presented to the gate device, such as a human body communication medium, is also referred to as a non-presentation medium.

JP 2007-172103 A

  There has never been a gate device that can use both non-presentation media and presentation media, but it may be developed in the future. When such a gate device is developed, a passer-by may have both a non-presentation medium and a presentation medium. When the passerby has both the non-presentation medium and the presentation medium, the gate device reads both the non-presentation medium and the presentation medium if the setting of the reading position and the reading timing of each medium is poor. At this time, if the gate device recognizes the presentation medium as that of the owner and recognizes the non-presentation medium as that of another passer, the passer and the medium cannot be correctly associated.

  In addition, even if the passerby has only one of the non-presentation medium and the presentation medium, if the reading position and reading timing of each medium are poorly set, the medium of the passerby who passes later will first pass through the passage. Reading before the passer's medium. At this time, if the gate device recognizes the medium of the passer-by who passes through the passage later as the passer-by who passes through the passage, the passer and the medium cannot be correctly associated.

  As described above, when the passer-by and the medium cannot be correctly associated with each other, there arises a problem that a passer-by who possesses the medium cannot pass through the passage, or a passer-by who does not have the medium can pass through the passage.

  Therefore, the present invention provides a gate device that can use a non-presentation medium and a presentation medium and correctly associate a passer-by with a presentation medium or a non-presentation medium used when the passer-by travels through a passage. The purpose is to do.

  In order to achieve the above object, the gate device of the present invention is configured as follows.

The gate device acquires the medium information from the presentation medium presented by the passer by the medium information acquisition unit on the entrance side of the passage. The presentation medium is a recording medium that allows a passer to actively present to a gate device and read recorded information, such as a magnetic ticket or a non-contact IC card. A human body communication antenna is installed behind the passage from the medium information acquisition unit, and communicates with a non-presentation medium possessed by the passer through the human body of the passer to acquire the medium information. A non-presentation medium is a recording medium that allows a passer to read recorded information only by possessing it without having to actively present it to a gate device, such as a human body communication medium. . When the medium information acquisition unit acquires the medium information from the presentation medium, the communication by the human body communication antenna is temporarily stopped. In this configuration, the passerby who actively presented the presentation medium also possesses a non-presentation medium. Even if it is, the non-presentation medium can be prevented from communicating with the gate device. Therefore, it is possible to correctly associate the passer-by with the presentation medium presented when the passer-by passes through the passage.

  In the gate device of the present invention, the first passage detection unit detects a passerby at the first passage detection position located between the medium information acquisition unit and the human body communication antenna. When the control unit detects a passerby at the first passage detection position and does not acquire medium information from the presentation medium, the control unit temporarily stops the medium information acquisition unit.

  In this configuration, before the human body communication antenna communicates with the non-presentation medium, the medium information acquisition unit does not acquire the medium information of another passer's presentation medium. Therefore, a passer-by and the non-presentation medium which the passer-by uses for passage of a passage can be correctly related.

  Moreover, if the medium information acquired from the presentation medium by the medium information acquisition unit is inappropriate, the gate device of the present invention continues the operation state without temporarily stopping the human body communication antenna.

  In this configuration, a passer-by has a presentation medium and a non-presentation medium, and even if the medium information of the presentation medium is inappropriate, the passer-by is allowed to pass if the medium information of the non-presentation medium is appropriate. Therefore, the medium information is acquired from the presentation medium by the human body communication antenna. Therefore, even if the media information of the presentation medium is inappropriate, if the passer possesses the non-presentation medium, this passer and the non-presentation medium possessed by this passer must be correctly associated. Is possible.

  In addition, the gate device of the present invention determines whether or not the medium information of the presentation medium acquired by the medium information acquisition unit is appropriate, the medium information is incorrect, and the previous usage information included in the medium information is If not appropriate, the communication by the human body communication antenna is temporarily stopped.

  If the media information of the presentation media presented by the passer is not appropriate and the previous usage information is not appropriate, there is a possibility that the boarding section and the usable period are inappropriate or the fare is insufficient. There is. In this configuration, in the above case, communication with the human body communication medium is stopped, so that this passer does not pass the passerby by the non-presentation medium, and the medium information of the presentation medium is properly set. So that passers-by can handle it.

  Further, in the gate device of the present invention, when the passerby is detected at the second passage detection position, if the communication by the human body communication antenna is in the stopped state or the medium information acquisition unit is in the stopped state, the gate device is returned to the operating state. . Therefore, the media information can be obtained immediately from the media of the next passer-by, and it is possible to correctly associate the passer-by with the presentation media or non-presentation media that the next passer-by uses when passing through the passage. it can.

  According to the present invention, the non-presentation medium and the presentation medium can be used, and the presenter or the non-presentation medium used when the passer-by passes through the passage can be correctly associated with the passer-by.

  Next, the operation of the automatic ticket gate 1 will be described. FIG. 4 is a flowchart for explaining the processing of the automatic ticket gate.

  In the control unit 10 of the automatic ticket gate 1, a magnetic ticket is inserted into the magnetic ticket slot 3A, or a non-contact IC card (hereinafter simply referred to as an IC card) is placed over the antenna 4A. I am waiting for you. The control unit 10 includes a magnetic ticket processing unit in which a magnetic ticket is inserted into the magnetic ticket insertion slot 3A or a non-contact IC card (hereinafter simply referred to as an IC card) is held over the antenna 4A. 3 or the RFID communication unit 4 acquires the ticket information recorded in the presentation medium (S1: Y), it is confirmed whether the ticket information is appropriate (S2). When the passer's entrance ticket gate process is performed, the control unit 10 determines whether an entry record is recorded on the presentation medium as previous usage information, whether the boarding section and the usable period are correct, and the like. When the control section 10 performs the entry ticket gate process for passers-by, the entrance information is recorded as the previous use information in the presentation medium, whether the boarding section and the usable period are correct, whether there is a fare shortage, etc. Judgment is made.

  When it is determined that the ticket information recorded on the presentation medium is appropriate (S2: Y), the control unit 10 temporarily stops the human body communication unit 5 (S3). As a result, even if this passerby possesses a human body communication medium in addition to a magnetic ticket or an IC card, it is possible to prevent erroneous processing on the human body communication medium. The presentation medium to be associated can be associated.

  Subsequently, the control unit 10 records the current usage information and the like on the presentation medium (S4). When performing the passer-by entrance process, the control unit 10 records the entrance information as the current use information on the presentation medium. When the passer's participation process is performed, the control unit 10 records the participation information which is the current usage information on the presentation medium, and performs a fare adjustment process.

  When the process of step S4 ends, the control unit 10 permits the passerby to pass, and causes the door drive processing unit 7 to open the door 7A installed on the exit side (S5).

  When the control unit 10 detects a passerby that has advanced to the second passage detection position by the second passage detection sensor 9B (S6: Y), the human body communication unit 5 temporarily stopped in step S3 is returned to the operating state. (S7). Thereby, the medium information can be quickly acquired from the human body communication medium of the passerby who next passes through the passage.

  And the control part 10 performs the process after step S1 again.

  On the other hand, if the control unit 10 determines in step S2 that the information recorded in the presentation medium is inappropriate (S2: N), the previous usage information is not appropriate for the presentation medium (S8: N) Other information is inappropriate. For example, information such as a boarding section and a usable period is not correct, or a fare shortage occurs. In this case, even if the passerby has a human body communication medium, passing it is a problem. Therefore, when the human body communication unit 5 is temporarily stopped (S9) and this passer possesses a human body communication medium in addition to the magnetic ticket or the IC card, the passer does not use the human body communication medium. Use to prevent passing through the passage.

  Subsequently, the control unit 10 prohibits the passerby from passing, and causes the door drive processing unit 7 to close the door 7A (S10). Then, the control unit 10 instructs the sound emission processing unit 2 and the display processing unit 8 to inform the speaker 2A and the liquid crystal monitor 8A of the reason for prohibiting passage and the handling method, and stops the ticket gate processing ( S11).

  In step S8, if the previous usage information is inappropriate on the presentation medium (S8: Y), the control unit 10 indicates that the information has not been correctly recorded on the presentation medium at the previous entry if it is an entrance. Can be considered. Also, at the time of participation, it is considered that the passerby possessed the human body communication medium but presented the presentation medium by mistake. In this case, if the passerby has a human body communication medium, no problem occurs even if the entrance process and the exit process are performed using the human body communication medium. Therefore, the control unit 10 does not prohibit the passage of the passerby, continues the operation state without temporarily stopping the human body communication unit 5, and waits for the detection of the passerby by the first passage detection sensor 9A ( S12: N). When the control unit 10 detects the passing person by the first passage detection sensor 9A (S12: Y), the control unit 10 temporarily stops the magnetic ticket processing unit 3 and the RFID communication unit 4 to display the presentation medium (magnetic ticket and The medium information is not acquired from the IC card) (S13). Further, when the controller 10 detects the passing person by the first passage detection sensor 9A (S12: Y) in step S1, in a state where the medium information is not acquired from the presentation medium (S1: N), the control part 10 performs step S13. Process. Thus, before the passer A passes through the human body communication pad 5A, medium information is acquired from the magnetic ticket or IC card from the next passer B, and the passer A's pass Misrecognition can be prevented. Therefore, the passer-by A can be correctly associated with the human body communication terminal possessed by the passer-by.

  The control part 10 makes the human body communication part 5 confirm whether it can communicate with a human body communication medium (non-presentation medium) until the 2nd passage detection sensor 9B detects a passer-by following the process of step S13. (S14: N, S15: N).

  When the control unit 10 can communicate with the human body communication medium via the passer's human body (S14: Y), the control unit 10 confirms whether the information recorded in the human body communication medium (non-presentation medium) is appropriate ( S16). When performing entry processing for passers-by, the control unit 10 determines whether an entry record is recorded as previous usage information on the presentation medium, whether the boarding section and the available period are correct, and the like. When the entry process of passers-by is performed, the control unit 10 records whether the entry information is recorded as the previous use information on the presentation medium, whether the boarding section and the usable period are correct, whether there is a shortage of fares, etc. Make a decision.

  If the control unit 10 determines that the information recorded in the human body communication medium is appropriate (S16: Y), the control unit 10 permits the passer-by to pass, and performs the processes after step S4 described above.

  On the other hand, if the information recorded in the human body communication medium is inappropriate in step S16, the control unit 10 prohibits the passer-by and passes the above-described processing after step S10.

  Further, in step S14, the control unit 10 cannot communicate with the human body communication medium (S14: N), and if the second passage detection sensor 9B detects a passerby (S15: Y), the passer Determine that you do not have a communication medium. And the control part 10 prohibits this passer's passage, and performs the process after the above-mentioned step S10.

  Thus, since the automatic ticket gate 1 of this embodiment performs the above-mentioned process, it can use both the magnetic ticket and IC card which are presentation media, and the human body communication media which are non-presentation media. Further, the passer-by can be correctly associated with the presentation medium or the non-presentation medium used when the passer-by passes through the passage.

  In the above description, the present invention has been described by taking an automatic ticket gate as an example to be used for a ticket gate operation at a station or the like. However, the present invention is not limited to this, and the present invention, such as entrance / exit management using human body communication, etc. Can be applied to various gate devices.

  The automatic ticket gate 1 has been described as being able to use three types of tickets: a magnetic ticket, an IC card, and a human body communication medium. However, the present invention is not limited to this, and a magnetic ticket and a human body communication medium or an IC card are used. Of course, it may be possible to use two types of tickets for human body communication media.

  In addition, the human body communication pad 5A has the electrode built-in, and the example in which the communication with the human body communication medium is performed through the human body by the electric field method has been described. However, the present invention is not limited to this, and Other systems that communicate with the human body communication medium (non-presentation medium) possessed by this passer-by may be used. For example, other methods such as a current method, UHF band electromagnetic wave method, elastic wave method (ultrasonic wave method), and evanescent communication method may be used.
