Abstract

<P>PROBLEM TO BE SOLVED: To allow persons, who wheels a truck loaded with baggage to pass a transportation management apparatus without bumping against a door without using a special transportation medium. <P>SOLUTION: When a person, who leaves from a management area 51, holds up a card 1 to a card reader 21a in a usual manner, card information is read out. Subsequently, a passage detection sensor, which is provided in the side of a passage 50a for main bodies 2a and 2c, detects the passage of the person, and then doors 24a and 24c are opened and then closed in the side of an exit so that only the person can pass. If the card 1 is continuously held up to the card reader 21a for more than a specified period or a plurality of times, the doors 24a and 24c are controlled so as to be opened and closed in the exit side without linking the number of times that the card 1 is read out with the number of traffic objects to be detected by the passage detection sensor. For example, even if the passage detection sensor detects two passing objects (baggage and a person who wheels a truck), the doors 24a and 24c are not closed. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a traffic management device that manages traffic of people by a traffic medium such as a card, such as an automatic ticket gate installed at a ticket gate of a station and a gate device installed at an entrance of a building.

  In recent years, automatic ticket gates that read card information of contactless cards such as commuter passes have been used. The automatic ticket gate determines whether or not the card user can pass based on the read card information. If it is determined to be allowed to pass, the door of the automatic ticket gate is opened, and if it is determined not to pass, the door is closed. ing. If the door is kept open when a certain user is allowed to pass, even those who do not have a valid card (regular card) will pass through the automatic ticket gate. Therefore, in order to prevent the passage of people who do not have a valid card, a person who passes through the automatic ticket checker is detected, and the door is opened and closed so that only one person can pass for the determination of one pass. I have control. That is, the door is closed when the passage of the second person is detected with respect to one pass determination. In addition, the door may be closed when the sensor detects that a person who has been permitted to pass has passed the automatic ticket gate.

  As described above, the passage of a person is detected by a sensor, but when the passerby is pushing a cart loaded with luggage, the sensor erroneously detects that the luggage is a person and the person pushing the carriage If you try to pass, the door closes, and there is a risk of the door hitting a person. Therefore, the passage position and speed of the vehicle (person or baggage) are detected by the sensor. When the door is closed, the closing speed of the door or the closed state of the door (fully closed or semi-closed) is determined based on the detected data. Control is proposed (for example, patent document 1).

  Also, if the door is closed immediately after the sensor detects that a person has passed, the elderly, wheelchair users, etc. will feel that the door is open for a short period of time, and the sensor will detect that the wheelchair has passed. However, when the wheelchair is not completely passed, there is a problem that the door contacts the wheelchair. Therefore, if an automatic ticket vending machine issues a dedicated card with data indicating that it is a wheelchair user, etc., and the automatic ticket checker reads the card, the passage exit indicates that the person has passed. It has been proposed to lengthen the time from when the sensor on the side detects until the door is closed, or to slow down the door closing speed (for example, Patent Document 2).

  Although not related to an automatic ticket gate, Patent Document 3 describes a room according to the number of times an entrance / exit card is held over a card reader within a certain time in an entrance / exit management device equipped with a non-contact type card reader. It is shown to unlock and lock the doors.

JP 10-21433 (paragraphs 0001 to 0014, 0036 to 0041) JP 2002-15343 A (paragraphs 0001 to 0018) JP 10-124634 A (summary)

  However, in the thing of the said patent document 1, when a sensor misdetects, the closing speed or closed state of a door is controlled so that a door may not hit a passerby, or it may not hit strongly even if it hits. However, when a false detection occurs, there is a problem that the door closes and traffic jam occurs in the automatic ticket gate. In the thing of the said patent document 2, since the time until the door is closed after the sensor of the exit side of a passage detects that a person passed, the problem that a door contacts a wheelchair is solved. The However, no consideration is given to the case where the sensor on the entrance side of the passage erroneously detects that the wheelchair is two passing bodies. In addition, a dedicated card used by a wheelchair user or the like must be issued by an automatic ticket vending machine separately from a card used by a general person, resulting in a problem that equipment costs increase as a whole system.

  The present invention solves the above-mentioned problems, and the problem is that a person who pushes a cart loaded with luggage does not hit the door without using a dedicated passage medium. The purpose of this invention is to provide a traffic management device that can be used.

  In the traffic management device according to the first aspect of the present invention, reading means for reading information recorded on a non-contact type traffic medium held over a communicable area, and a user of the traffic medium based on the information read by the reading means Passability determination means for determining whether or not traffic is allowed, an openable / closable door that restricts or allows user traffic, and if the pass / fail judgment means allows the user to pass. An open / close control means for controlling the opening and closing of the door and controlling the opening and closing of the door so as to restrict the passage of the user when the determination result of the passage permission / inhibition determining means is a passage failure. In the case where the determination result is passable, at least one of the cases where the passable medium is continuously held over the communicable area for a predetermined time or more than once in the communicable area. , Opening and closing control means, passing the medium to open and close control of the door in a manner different from the case of addition to being held over a short time than a predetermined time once a communicable area.

  As described above, when a person who takes time to pass, such as a person pushing a cart loaded with luggage, keeps the passing medium over the communicable area for more than a predetermined time, or by holding it over several times, The opening / closing of the door is controlled in a manner different from when the passing medium is held over the communicable area. For example, the opening and closing of the door is controlled so that the door is not closed during passage of a person who takes time to pass. Thereby, even if it is a person who takes time for traffic, it does not hit a door and can pass through a traffic management apparatus in comfort. In addition, since it is not necessary for a person who takes time to travel to use a dedicated traffic medium, the equipment cost of a traffic management system including a traffic medium issuing machine does not increase.

  In an embodiment of the first invention, the opening / closing control means controls the opening / closing of the door so that the opening time of the door in the at least one case is longer than the opening time of the door in the other cases. it can. Thereby, in at least one of the above cases, even a person who takes time to pass does not hit the door, and can pass through the traffic management device with peace of mind.

  In the traffic management device according to the second invention, the reading means for reading the information recorded on the non-contact type traffic medium held over the communicable area, and the user of the traffic medium based on the information read by the reading means A passage permission / non-permission determining means for determining whether or not a person can pass; an openable / closable door that restricts or allows a user's passage; a sensor that detects a user's passage; and the number of passages determined by the passage permission / inhibition determining means. An opening / closing control means for associating the number of passing bodies detected by the sensor with each other and allowing the opening of the doors so as to allow the passage of the number of users that are allowed to pass. When the determination result is passable, at least one of the case where the passable medium is continuously held in the communicable area for a first predetermined time or more and the passable medium is held in the communicable area a plurality of times Expediently, the switching control means, the number and sensor Allowed, determined in passing determination means without associating the number of traffic body detecting, controlling opening and closing the door.

  In this way, for example, when a person pushing a cart loaded with luggage continues to pass the passage medium over the communicable area for a first predetermined time or more than one time, or the sensor is loaded with the luggage and the cart. Even if the person who presses the button is recognized as a user, the number of passable objects determined by the passability determination means is not associated with the number of vehicles detected by the sensor. The door can be opened and closed so that the door does not close inside. Here, the sensor is a combination of the traffic detection sensor shown in the embodiment and the function of the control unit. The vehicle detected by the sensor is a load, a person pushing a cart, or the like. As a result, even a user who has a high possibility of recognizing that the sensor is a plurality of traffic bodies does not hit the door, and can pass through the traffic management device with peace of mind. Further, since the user does not need to use a dedicated traffic medium, the equipment cost of the traffic management system including the traffic medium issuing machine is not increased.

  In an embodiment of the second invention, in at least one of the cases described above, the opening / closing control means allows the passage of a vehicle detected by a predetermined number of sensors for one passage. Can be controlled to open and close. Thereby, for example, if the predetermined number is set to 2, even if the sensor recognizes the baggage and the person pushing the carriage as users, the door is prevented from closing during passage. . In addition, when the sensor detects more than a predetermined number of passing bodies, it is possible to restrict unauthorized passing by closing the door.

  In an embodiment of the second invention, in at least one of the cases described above, the opening / closing control means can control the opening / closing of the door so that the door is opened for a second predetermined time. In this way, even when the sensor recognizes the baggage and the person pushing the carriage as the user, the door is opened only for the second predetermined time. The door is prevented from closing. The second predetermined time is a time when even a person who takes time to pass, such as a person pushing a cart loaded with luggage, can pass with a margin.

  According to the present invention, even if a person who takes time to pass, such as a person pushing a cart loaded with luggage, can use the traffic management device without worrying about the door without using a dedicated traffic medium. can do.

  Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

FIG. 4 is a block diagram showing an electrical configuration of a card reader used in the traffic management device. The traffic management devices are respectively installed at the entrance and the exit of the management area 51 where entry of people such as the inside of a building or the station premises is restricted. The exit traffic management device is composed of a pair of main bodies 2a and 2c arranged in parallel, and the entrance traffic management device is composed of a pair of main bodies 2b and 2c arranged in parallel. The management area 51 is partitioned by a partition wall 53 from a non-management area 52 where a person can freely enter.

  Card readers 21a and 21b are provided in the main bodies 2a and 2b, respectively, and those who leave the management area 51 and those who enter the management area 51 are effective (regular) non-contact traffic media. By allowing the card reader 21a, 21b to read the card 1, it is possible to pass through the passages 50a, 50b of the traffic management device. In FIG. 1, the cover of the antenna coil (antenna) of the card reader is shown as card readers 21a and 21b. The card 1 is recorded with card-specific information indicating that the card is used in the traffic management device, a card number for identifying the card user, and the like (hereinafter collectively referred to as card information). Yes. Although it may be determined whether the card is a valid card including a card number or the like, the card 1 in which correct card unique information is recorded is treated as a valid card here.

  Card display portions 22a and 22b are provided in front of the card readers 21a and 21b, respectively. On the card display units 22a and 22b, a message (hereinafter also referred to as an OK message or an NG message) indicating whether or not traffic is permitted is displayed according to the validity / invalidity of the card 1 read by the card readers 21a and 21b. Further, a passage permission / indication display unit 27 is provided on the front surface of the main body 2. For example, “○” indicating that the passage 50a is allowed to pass through the front passage permission / inhibition display portion 27 on the management area 51 side of the main body 2a. ”Is displayed, and“ × ”indicating that the vehicle is not allowed to be displayed is displayed on the pass / fail display portion 27 on the back surface of the main body 2a on the non-management area 52 side.

  Doors 23a and 24a are provided on the passage 50a side of the main body 2a, doors 23b and 24b are provided on the passage 50b side of the main body 2b, doors 23c and 24c are provided on the passage 50a side of the main body 2c, and the passage 50b side of the main body 2c is provided. The doors 23d and 24d are provided to be openable and closable. The doors 23a, 23c, 24b, and 24d are always open. Further, the doors 24a, 24c, 23b, and 23d are normally closed, and the passage of an invalid (unauthorized) user of the card 1 or a person who does not have the card 1 (hereinafter also referred to as an impassable person) is restricted (prohibited). Is done. When the valid card 1 is read by the card reader 21a (21b), the doors 24a and 24c (doors 23b and 23d) on the exit side are opened as shown by the arrow A (arrow B) in FIG. (Hereinafter also referred to as a passable person).

  When exiting, the upper side of FIG. 1 is the entrance side, and the lower side is the exit side. When entering, the entrance side and the exit side are reversed when leaving. In the present embodiment, the doors 23a and 23c that are always open are unnecessary. However, when the passage 50a is used as an entrance / exit passage, the doors 23a and 23c and the like are also opened and closed. A card reader is also provided on the unmanaged area 52 side.

  Further, on the passage 50a side of the main bodies 2a and 2c, passage detection sensors 25 and 26 for detecting a passerby are provided. The traffic detection sensors 25 and 26 are transmissive optical sensors, and a projector is attached to one main body 2a, and a light receiver is attached to the other main body 2c. Detection signals from the passage detection sensors 25 and 26 are sent to the control unit 20, and the control unit 20 controls the opening and closing of the doors 23 and 24 based on the detection signals. For example, when the passage detection sensor 25 on the entrance side detects passage of a passable person, the control unit 20 opens the doors 24a and 24c. A similar passage detection sensor (not shown) is also provided on the side of the passage 50b of the main bodies 2b and 2c.

  The electrical configuration of the traffic management device will be described with reference to FIG. The control unit 20 is provided in any one of the main bodies 2 and includes a CPU 20a, a memory 20b, and the like. The control unit 20 stores the card information from the card reader 21 and the detection signals of the traffic detection sensors 25 and 26 in the memory 20b, and based on the card information and the detection signals, the card display unit 22 and the door opening / closing drive unit 28. To control. The door opening / closing drive unit 28 drives a door opening / closing mechanism (not shown) according to a signal from the control unit 20, thereby opening and closing the doors 24a, 24c and the like. That is, the control unit 20 controls opening and closing of the doors 24a and 24c. In addition, the control unit 20 displays the above-described symbol indicating whether or not passage is permitted on the passage permission / rejection display unit 27 according to the operation mode of the traffic management device.

  Although the card reader 21 itself used in the present invention is known, a method for reading the card information recorded on the card 1 with the card reader 21 will be briefly described. The non-contact card 1 includes an antenna coil and an IC chip connected to the antenna coil, and the IC chip includes a transmission circuit, a reception circuit, a control circuit, a memory in which card information is recorded, and the like. On the other hand, as shown in FIG. 4, the card reader 21 is an I / F that is a communication interface to the antenna coil 216, the transmission circuit 214 and the reception circuit 215 connected to the antenna coil 216, the CPU 210, the memory 211, and the control unit 20. A circuit 212 and a clock circuit 213 are provided. Then, when the card 1 is held over the operating magnetic field range (communication possible area) of the card reader 21, by detecting the fluctuation of the magnetic field caused by changing the current flowing in one antenna coil by the other antenna coil, Communication is performed between the card 1 and the card reader 21.

  In this communication, the card reader 21 transmits a command, and the card 1 that has received the command transmits card information. Further, the card reader 21 stores the read card information in the memory 211. When the CPU 210 receives a card information transmission instruction from the control unit 20 of the traffic management device, the CPU 210 transmits the card information stored in the memory 211 to the control unit 20. If the card information is not stored in the memory 211, the fact that there is no card information is transmitted. Further, as will be described later, the time when the card 1 is continuously held over the card reader 21 is obtained using the time read from the clock circuit 213.

  The operation of the card reader 21 will be described with reference to FIGS. The following operations are the same in the second and third embodiments described later, and are realized by the CPU 210 executing a program stored in the memory 211 of the card reader 21. When the traffic management device is turned on, the main process is started. First, 0 is set to a variable whose area is secured in the memory 211, that is, a card detection flag and a continuation flag (S1). Next, a card reading process is performed to read card information from the card 1 (S2). Although details of the card reading process will be described later, an outline of the card reading process will be described here.

  When the card 1 is held over the communicable area of the card reader 21 and the card information is read by the card reader 21, the above-mentioned card detection flag is set to 1, and the transmission buffer whose area is secured in the memory 211 Card information and continuation time are written in The continuous holding time is the time that the card 1 has been held over the communicable area of the card reader 21. For example, when the card 1 is held over the communicable area for 2 seconds, the card information is read many times, but when it is read for the first time, the card information and the continuous holding time (in this case “0”) is 1. When the data is written into the transmission buffer as a set of data and cannot be read (after 2 seconds have elapsed), the card information and the continuous holding time (2 seconds) are written into the transmission buffer.

  The duration is determined as follows. When the card information is first read, the card information and the time read from the clock circuit 213, that is, the read time is stored in a temporary buffer whose area is secured in the memory 211. Then, the continuous holding time is obtained by subtracting the reading time from the time read from the clock circuit 213 when the card information can no longer be read. The continuation flag is set to 1 when the same card information is read in the previous reading process and the current reading process, and is set to 0 when different card information is read.

  After the card reading process (S2), it is checked whether or not a card information transmission instruction is received from the control unit 20 (S3). If not received (S3: NO), the process returns to S2 and the card reading process is performed again. I do. If received (S3: YES), it is checked whether there is card information to be transmitted to the transmission buffer (S4). When there is card information to be transmitted (S4: YES), the card information and the continuation time are read from the transmission buffer and transmitted to the control unit 20 (S5), and the process returns to S2. If there is no card information to be transmitted (S4: NO), the fact that there is no card information is transmitted to the control unit 20 (S6), and the process returns to S2.

  Next, the card reading process will be described with reference to FIG. First, a command is transmitted to the card 1 in order to read the card information of the card 1 (S11). This command changes the current flowing through the antenna coil 216, and as a result, the magnetic field passing through the antenna coil 216 changes. When the card information is received from the card 1 by transmitting the command (S12: YES), it is checked whether or not the card detection flag is 0 (S13). When the card detection flag is 0, that is, when the card 1 is read first (S13: YES), the card detection flag is set to 1 (S14), and the received card information and the above-described reading time are set as one set. Is stored in the temporary buffer as data (S15). Further, the received card information and the continuation holding time (here, “0” indicating the first reading) are written in the transmission buffer (S16), and the process returns to the main process.

  If the card detection flag is not 0 (1) (S13: NO), whether the same card information as the previous time was received by comparing the card information stored in the temporary buffer with the received card information Whether or not is checked (S17). When the same card information as the previous time is received (S17: YES), 1 is set in the continuation flag indicating that the same card information is continuously received (S18), and the received card information is stored in the temporary buffer and the transmission buffer. Return to the main process without writing. When the same card information as the previous time is not received (S17: NO), it is checked whether or not the continuation flag is 0 (S19). If it is 0 (S19: YES), since the card information of the new card 1 is read, the received card information and the above-mentioned reading time are stored in the temporary buffer (S15), and the received card information and the continuation holding are held. The time (here, “0”) is written in the transmission buffer (S16), and the process returns to the main process.

  If the continuation flag is not 0 (1) (S19: NO), the continuation flag is set to 0 (S20). In this case, card information and reading time when the card 1 that has been held over the card reader 21 continuously until the previous time is first read are stored in the temporary buffer. Therefore, the continuation time is calculated by subtracting the reading time from the time read from the clock circuit 213 (S21). Since the time for the card reader 21 to read the card information from the card 1 is sufficiently shorter than the time for the person to hold the card 1 over the card reader 21, the calculated continuous holding time is actually the card Is approximately equal to the time over which Then, the card information in the temporary buffer and the calculated continuous holding time are written in the transmission buffer as a set of data (S22). Further, since the card information of the new card 1 is read, the received card information and the above-described reading time are stored in a temporary buffer (S15), and the received card information and the continuous holding time (here, “0”). Is written in the transmission buffer (S16), and the process returns to the main process.

  If it is determined in S12 that the card information has not been received (S12: NO), it is checked whether the card detection flag is 1 or 0 (S23). If the card detection flag is 0 (S23: NO), the process returns to the main process. If the card detection flag is 1 (S23: YES), 0 is set in the card detection flag (S24), and it is checked whether the continuation flag is 1 or 0 (S25). If the continuation flag is 0 (S25: NO), the process returns to the main process. When the continuation flag is 1 (S25: YES), the continuation flag is set to 0 (S26), and the continuation holding time is calculated from the reading time in the temporary buffer in the same manner as S21 and S22 (S27). The card information in the temporary buffer and the calculated continuation time are written in the transmission buffer as a set of data (S28), and the process returns to the main process.

  Next, an outline of the operation of the traffic management device regarding exit from the management area 51 will be described. The operation related to entry is the same as the operation related to exit. The doors 24a and 24c on the exit side are normally closed. When the valid card 1 is held over the card reader 21a, the doors 24a and 24c are opened, and the user of the valid card is allowed to pass. When the passage detection sensor 26 on the exit side detects the passage of the user, the doors 24a and 24c are closed. Further, when the entrance-side passage detection sensor 25 detects the passage of the inaccessible person while the doors 24a and 24c are open, the doors 24a and 24b are closed, and the passage of the inaccessible person is restricted (prohibited). That is, the passage of passers-by is managed by associating the number of read valid cards 1 with the number of passers-by passing through the passage 50a.

  In this way, when a person pushing a cart loaded with luggage (hereinafter referred to as a cart user) passes the valid card 1 over the card reader 21a and passes through the passage 50a, the traffic detection sensor 25 or 26 is loaded with the luggage or the cart. If it is determined that the user is a passer-by, the doors 24a and 24c are closed even though the cart user does not pass through the passage 50a. Therefore, in the present invention, when the valid card is held over the card reader 21a a plurality of times (for example, three times or more) or continuously for a predetermined time (for example, two seconds or more), it is read. The number of valid cards 1 (hereinafter also referred to as “permitted traffic”) and the number of traffic bodies (here, carts, luggage, cart users) detected by the traffic detection sensors 25 and 26 (hereinafter referred to as “detected traffic”). The traffic of the passerby is managed so as not to correspond to the number of bodies.

  As this management method, there are a passage permission number constant mode and a passage permission number indefinite mode, and either mode is selected according to data preset in the memory 20b of the control unit 20. In the constant traffic allowance mode, only one set number of traffic (for example, 2) preset in the memory 20b is allowed for one pass permission. In the indefinite number of allowed traffic mode, the card is detected regardless of the number of vehicles detected by the traffic detection sensors 25 and 26 until a predetermined time (for example, 10 seconds) elapses from when the card 1 is held over as described above. , Allow the passage of traffic. Increasing the number of allowed settings or the predetermined time allows the cart user to pass through with certainty, but causes the problem of allowing the passage of persons who cannot pass. Therefore, the optimum setting permission number and the predetermined time are determined in consideration of the usage status of the traffic management device.

  Next, with reference to FIG. 7 and FIG. 8, the detail of operation | movement of the traffic management apparatus regarding the above-mentioned leaving is demonstrated. The operations shown below are realized by the CPU 20a executing programs for main processing, traffic detection processing, and timer processing stored in the memory 20b of the control unit 20. In addition, a management program (not shown) manages execution of three processing programs. Normally, main processing is executed, and traffic detection processing and timer processing are executed at regular intervals. In the following description, it is assumed that the traffic detection process is activated every 50 milliseconds and the timer process is activated every 100 milliseconds. When the traffic management device is turned on, the main process is started. First, 0 is set to the following four variables whose areas are secured in the memory 20b of the control unit 20, that is, the number of persons permitted to pass, the normal passing timer, the extended passing timer, and the door closing timer (S41).

  The number of permitted persons indicates the number of persons who can pass through the traffic management device, and is incremented by 1 each time the valid card 1 is read by the card reader 21a. Next, the normal traffic timer will be described. After the valid card 1 is read by the card reader 21a, if the card user returns to the management area 51 without leaving the management area 51, 1 is added to the permitted number of passages. You can leave. In order to prevent such a situation, when a certain time (for example, 5 seconds) has passed since the last time the valid card 1 was read, 0 is set as the number of persons permitted to pass. It is a normal traffic timer that manages this fixed time. Since the timer process is started every 100 milliseconds as described above, the above-mentioned fixed time (5 seconds) is realized by setting 50 for the normal travel timer.

  Next, the extended traffic timer will be described. The extended traffic timer is a timer used for the same purpose as the normal traffic timer, and is set when the valid card 1 is continuously held over the card reader 21a for a predetermined time or more than once. . The extended traffic timer is set to a value that realizes a certain time (for example, 10 seconds) that is greater than the normal traffic timer. As described above, since the timer process is started every 100 milliseconds, the predetermined time (10 seconds) is realized by setting 100 to the extended traffic timer. The door closing timer is a timer for managing the time from when the card user's traffic is detected by the exit-side traffic detection sensor 26 until the doors 24a and 24c are closed.

  Return to the description of the main process. After S41, the doors 23a and 23c on the inlet side are opened, and the doors 24a and 24c on the outlet side are closed (S42). Next, the card reader 21a is instructed to transmit the card information read from the card 1 (S43). Upon receiving this instruction, the card reader 21a transmits the read card information and the continuation time to the control unit 20 as described above. If the card information has not been read, a message to that effect is sent. If the card information is not received from the card reader 21a (S44: NO), the card reader 21a is again instructed to transmit the card information read from the card 1 (S43). When the card information is received (S44: YES), either the valid card 1 or the invalid card 1 is checked by checking the card specific information (information indicating that the card 1 is used in the present apparatus) in the card information. It is checked whether it is card information (S45).

  If it is card information of the invalid card 1 (S45: NO), an NG message is displayed on the card display unit 22a to indicate that traffic is restricted (prohibited) (S58), and the process returns to S43. If it is the card information of the valid card 1 (S45: YES), an OK message is displayed on the card display unit 22a to indicate that passage is permitted (S46). Next, the value of the continuation holding time received together with the card information is checked (S47). When the value of the continuous holding time is 0, that is, when the received card information is the card information read first when the card 1 is held over the card reader 21a (S47: YES), the received card It is checked whether the information is different from the previously received card information (S48).

  If it is different, that is, if it is card information of a new card 1 (S48: YES), 1 is set as the number of repetitions which is a variable for counting the number of times the card 1 is held over the card reader 21a (S49). Then, 1 is added to the number of persons permitted to pass (S50). Further, the set value (50) is set in the passage permission timer, 0 is set in the door closing timer (S51), and the process returns to S43. Since the door closing timer is set to 0 in this way, the door closing timer activated by the passage of the previous card user is timed out, thereby preventing the doors 24a and 24c on the exit side from being closed. .

  In S48, when it is determined that the received card information is the same as the previously received card information, that is, when the card 1 is held over again (S48: NO), 1 is added to the number of repetitions described above (S52). . If the number of repetitions does not exceed the predetermined number even after addition (S53: NO), the process returns to S43. If the number of repetitions is equal to the predetermined number as a result of the addition (S53: YES and S54: YES), whether the traffic management device is operating in the above-described constant traffic permission mode or the traffic permission number indefinite mode. (S55). When operating in the constant passage permitted number mode (S55: YES), (the above-mentioned set permitted number -1) is added to the number of permitted passages (S56). Since 1 is already added to the number of permitted persons when the card information of the card 1 held for a predetermined number of times is first received (S50), the set permitted number (for example, 2) is added to the permitted number of persons. It will be done. In this way, the number of permitted sets and the number of detected vehicles are associated with one pass permission. In other words, the number of traffic permits is corrected by the number of permitted settings. Then, as will be described later, the doors 24a and 24c are controlled to be opened and closed so as to allow the passage of detected passing bodies corresponding to the set permitted number.

  Next, the set value (100) is set in the extended passage timer, and 0 is set in the door closing timer (S57), and the process returns to S43. In the constant traffic allowance mode, the doors 24a and 24c are closed when the passage detection sensor 26 on the exit side detects the passage of the set number of passable vehicles, so that the normal traffic is passed to the extended traffic timer. Even if the same setting value (50) as that set in the timer is set, the operation of the traffic management device is not affected.

  On the other hand, when operating in the indefinite number of allowed traffic mode (S55: NO), as described above, the number of permitted traffic and the number of detected vehicles are not associated with each other. Without adding to, the above set value (100) is set in the extended passage timer, the door closing timer is set to 0 (S57), and the process returns to S43. Here, the setting value (100) of the extended traffic timer is set to be larger than the setting value (50) of the normal traffic timer, but a person pushing a cart loaded with luggage can pass through the traffic management device with a margin. Since it is sufficient if the time can be realized by the extended traffic timer, the set value of the extended traffic timer does not necessarily need to be larger than the set value of the normal traffic timer. On the other hand, when the number of repetitions is larger than the predetermined number (S53: YES and S54: NO), the set permission number is already added to the permitted number of people (S50, S56), so the number is added to the permitted number of people. Without setting the above set value in the extended traffic timer, the door closing timer is set to 0 (S57), and the process returns to S43.

  If it is determined in S47 that the value of the received continuous holding time is not 0 (S47: NO), it is checked whether or not the continuous holding time is equal to or longer than a predetermined time (S59). If it is longer than the predetermined time (S59: YES), S55 to S57 described above are executed, and the process returns to S43. If it is less than the predetermined time (S59: NO), the process returns to S43 without doing anything. Regarding the card information, the above-described S49 to S51 are executed when the card information is first received.

  Next, the traffic detection process will be described with reference to FIG. When the traffic detection process is activated, it is checked whether or not the traffic detection sensor 25 on the entrance side detects the traffic of the passerby (S101). Specifically, the output signal of the traffic detection sensor 25 at the time of the previous traffic detection process stored in the memory 20b of the control unit 20 is compared with the current output signal, and the output signal is transmitted from the light-shielded state. If the state has changed, it is determined that traffic has been detected. When the passage of the passerby is not detected (S101: NO), the process proceeds to S105.

  When the passage of a passerby is detected (S101: YES), if the value of the permitted number of people is 0 (S102: YES), close the doors 24a and 24c on the exit side if they are open (S103), and go to S105. move on. As a result, the passage of the inaccessible person detected by the entrance detection sensor 25 is restricted. On the other hand, when the value of the number of permitted persons is not 0 (S102: NO), if the doors 24a and 24c on the exit side are closed, they are opened (S104), and the process proceeds to S105. As a result, the passable person detected by the entrance-side traffic detection sensor 25 is allowed to pass.

  In S105, it is checked whether or not the passage detection sensor 26 on the exit side detects passage of a passerby. Specifically, the output signal of the traffic detection sensor 26 stored in the memory 20b of the control unit 20 in the previous traffic detection process is compared with the current output signal, and the output signal is transmitted from the light-shielded state. If the state has changed, it is determined that traffic has been detected. When the passage of the passerby is not detected (S105: NO), the process returns to the caller without doing anything. When the passage of a passerby is detected (S105: YES), the following three processes are performed.

  First, when the value of the extended traffic timer is 0, that is, when processing is performed by holding the card 1 in a normal manner (S106: YES), the number and detection of traffic permission are detected as follows. The traffic management is performed in association with the number of traffic bodies to be used. First, if the value of the permitted number of persons is not 0 (S108: NO), 1 is subtracted from the permitted number of persons (S109). Further, when the value of the permitted number of people is 0 as a result of the subtraction (S110: YES), the first or second set value is set as the door closing timer based on whether or not the value of the extension timer is 0 ( S111), the process returns to the caller. In this case, since the value of the extension timer is 0, the first set value is set. This door closing timer is subtracted by a timer process described later, and when the value becomes 0, the doors 24a and 24c on the outlet side are closed.

  Here, the second setting value (for example, 20) set when the value of the extension timer is not 0 is set to a value larger than the first setting value (for example, 10). This is so that the person who pushes the carriage can pass with peace of mind. As can be seen from the positional relationship between the door 24a and the traffic detection sensor 26 shown in FIG. 2A, even if the doors 24a and 24c are closed immediately after the traffic detection sensor 26 on the outlet side detects the traffic, No one hits you. Therefore, from the viewpoint of preventing the doors 24a and 24c from hitting passers-by, it is not always necessary to control the doors 24a and 24c using the door closing timer, and the doors 24a and 24c are closed in S111. Also good.

  Secondly, when the value of the extended traffic timer is not 0 and the traffic management device is operating in the constant traffic allowance mode (S106: NO and S107: YES), the same as in the first case. Execute S108 to S111 and return to the caller. In this way, the traffic management is performed by associating the number of permitted passages corrected by the above-described number of permitted settings with the number of detected vehicles.

  Thirdly, when the value of the extended traffic timer is not 0 and the traffic management device is operating in the traffic permission count indefinite mode (S106: NO and S107: NO), the traffic detected as the number of traffic permits is detected. Since it is not associated with the number of fields, it returns to the caller without doing anything. In this case, as will be described later, when the extended passage timer expires, the doors 24a and 24c on the exit side are closed.

  Next, the timer process will be described. When the timer process is started, if the value of the normal traffic timer is not 0, 1 is subtracted from the normal traffic timer (S121, S122), and if the value of the extended traffic timer is not 0, 1 is subtracted from the extended traffic timer. (S123, S124). Next, if both the normal traffic timer and the extended traffic timer are 0, the permitted traffic number is set to 0, and if the exit doors 24a and 24c are open, they are closed (S125 to S127). Next, it is checked whether or not the value of the door closing timer is 0 (S128). If it is not 0 (S128: NO), 1 is subtracted from the door closing timer (S129). As a result of the subtraction, when the value of the door closing timer becomes 0 (S130: YES), if the doors 24a and 24c on the outlet side are open, they are closed (S131) and the process returns to the caller.

  A second embodiment of the present invention will be described. In the previous embodiment, the doors 24a, 24c on the exit side of the traffic management device are normally closed, and when the valid card 1 is read by the card reader 21, the doors 24a, 24c, etc. are opened to detect the passage of the card user. The doors 24a and 24c are closed after a predetermined time has elapsed. In this embodiment, as shown in FIG. 9, the doors 23 a to 23 d and 24 a to 24 d are normally opened, and the entrance-side detection sensor 25 detects that the inaccessible person has left, the exit-side doors 24 a and 24 c are opened. Close as shown by arrow C. Further, when a passage detection sensor (not shown) on the entrance side detects entry of a person who cannot pass, the doors 23b and 23d on the exit side are closed as indicated by an arrow D.

  Next, with respect to the operation of the traffic management device regarding exit from the management area 51, differences from the previous embodiment in the main process will be described. In the present embodiment, the doors 23a and 23c on the entrance side and the doors 24a and 24c on the exit side are opened instead of the process of S42 (FIG. 7). Further, since the doors 24a and 24c on the exit side are normally opened, the door closing timer is unnecessary, and there is no processing (S41, S51, S57) for setting the door closing timer to 0.

  Next, differences between the traffic detection process and the timer process will be described. FIG. 10 is a flowchart showing the operation of this embodiment. The steps of FIG. 10 corresponding to the steps of FIG. 8 of the previous embodiment are numbered by adding 100 to the step number of FIG. In the present embodiment, the doors 24a and 24c on the exit side are normally opened, so there are no steps corresponding to S110 to S111 and S127 to S131 in FIG. This is different from the previous embodiment. Therefore, the doors 24a and 24c are closed only in the present embodiment when the passage of the inaccessible person is detected by the entrance-side passage detection sensor 25 when the number of permitted persons is zero (S202, S203). .

  Next, a third embodiment of the present invention will be described. In the first embodiment, traffic detection sensors 25 and 26 are provided on the passages 50a and 50b side of the main body 2 of the traffic management device, and traffic management is performed by detecting persons who actually pass through the traffic detection sensors 25 and 26. However, the traffic management device of this embodiment does not use a traffic detection sensor. In this embodiment, as shown in FIG. 1, the doors 24a, 24c on the exit side are normally closed, and when the valid card 1 is read by the card reader 21, the doors 24a, 24c, etc. are opened, and a predetermined time has passed. When elapses, the doors 24a, 24c and the like are closed. Further, when the valid card 1 is continuously held over the card reader 21 for a predetermined time or more than once, or when it is held over several times, the opening time of the doors 24a, 24c and the like is set in the usual manner. I try to make it longer than if it was.

  FIG. 11 is a flowchart of the main process of this embodiment, and FIG. 12 is a flowchart of the timer process. In the present embodiment, since no traffic detection sensor is used, there is no traffic detection processing. The steps in FIG. 11 corresponding to the steps in FIG. 7 of the first embodiment are given numbers obtained by adding 300 to the step numbers in FIG. The difference between FIG. 7 and FIG. 11 will be described below. In the present embodiment, since the traffic management based on the permitted number of traffic is not performed, steps corresponding to S50 and S54 to S56 in FIG. 7 do not exist in FIG. In addition, there is no process for setting the number of permitted persons to 0 (S341).

  In the present embodiment, since the doors 24a and 24c are closed after a predetermined time has elapsed since the doors 24a and 24c are opened, the door closing timer is unnecessary, and the process for setting the door closing timer to 0 is performed. Does not exist (S341, S351, S357). Furthermore, since the opening times of the doors 24a and 24c are determined by the normal passage timer and the extended passage timer, in the present embodiment, a set value larger than a set value (for example, 50) (S351) set in the normal pass timer. (For example, 100) is set as an extended traffic timer (S357).

  Next, the timer process of this embodiment will be described with reference to FIG. First, it is checked whether or not the values of the normal traffic timer and the extended traffic timer are both 0 (S371). When both are 0 (S371: YES), if the doors 24a and 24c on the outlet side are open, they are closed (S372). If either is not 0 (S371: NO), the doors 24a, 24c on the outlet side are opened (S373). Next, if the value of the normal traffic timer is not 0, 1 is subtracted from the normal traffic timer (S374 to S375). Further, if the value of the extended traffic timer is not 0, 1 is subtracted from the extended traffic timer (S376 to S377), and the process returns to the caller.

  As described above, when the valid card 1 is read by the card reader 21a and the set value is set in the normal passage timer or the extended passage timer (S351, S357), the doors 24a and 24c are opened, and the normal time has passed. When the values of the traffic timer and the extended traffic timer are both 0, the doors 24a and 24c are closed.

  In the first to third embodiments described above, when the card 1 is continuously held over the communicable area of the card reader 21a for a predetermined time or more, and when it is held over the communicable area a plurality of times, a normal method is used. The doors 24a and 24c are controlled to be opened and closed in a manner different from the opening and closing control of the doors 24a and 24c performed when the card 1 is held over, but the opening and closing control is performed in a different manner only in either case. May be.

  In the second embodiment, each traffic management device is dedicated to entry or exit. However, the present invention can also be implemented by managing entrance and exit with a single traffic management device. In this case, when the passage detection sensor 26 on the non-management area 52 side detects the passage of a person who cannot enter, the doors 23a and 23c on the management area 51 side are closed, and the passage detection sensor 25 on the management area 51 side leaves. When the passage of the inaccessible person is detected, the doors 24a and 24c on the non-management area 52 side are closed.
