Description

  The present invention relates to a traffic management device that manages entry into or exit from a management area where entry of people is restricted by a traffic medium such as a card.

  In the past, admission of outsiders, outsiders, etc. (hereinafter collectively referred to as outpatients) has been regulated, and the outsiders are not allowed to enter a management area such as a building or a restricted area within the building. In order to prevent entry, a receptionist manages the entrance of a visitor, but it has been proposed to save labor in reception work as follows (for example, Patent Document 1). When an entrance gate is set up at the entrance of the management area, and the visitor inserts an visitor card issued for each visitor into the entrance gate, the entrance gate door opens and allows entry. In addition, an exit gate is provided at the exit of the management area, and when the visitor inserts the visitor card into the exit gate, the exit gate door opens and can be exited.

  In addition, in order to allow multiple people to pass through the automatic ticket gate using a single contactless IC card, an operation unit is provided for inputting the number of people passing through the automatic ticket gate, allowing only the entered number of people to pass. It has been proposed to collect a fee commensurate with the number of people from the balance of the IC card (for example, Patent Document 2). In addition, instead of providing an operation unit in the automatic ticket gate, an operation unit for inputting the number of people who pass through the non-contact type IC card itself and a display unit for displaying the number of people entered are provided, and the automatic ticket gate has the IC It has also been proposed that by reading the data of the number of people set in the card, only that number of people is allowed to pass, and a fee corresponding to the number of people is collected from the balance of the IC card (for example, Patent Document 3). Furthermore, although using a magnetic card, an automatic ticket vending machine issues a group ticket that records the number of groups, and opens and closes the automatic ticket gate door so that only the number recorded on the group ticket can pass. It is also proposed to control (for example, Patent Document 4).

JP-A-11-259712 (paragraphs 0024 to 0030) JP-A-10-198827 (Claim 1, paragraphs 0011 to 0026) JP 2002-109579 A (Claim 1, paragraphs 0020 to 0080) JP 7-78277 A (Claim 1, paragraphs 0011 to 0030)

  However, in the case of the above-mentioned Patent Document 1, even if the visitor consists of several groups, the visitor card must be issued for each visitor, and it is troublesome to issue the visitor card. There is a problem that it is expensive. In the device disclosed in Patent Document 2, an operation unit for inputting the number of persons must be provided in the automatic ticket gate, which increases the manufacturing cost of the automatic ticket gate. In addition, since it takes time for the user to input the number of people, the automatic ticket gate becomes crowded during morning and evening rush hours.

  In what is shown in Patent Document 3, a special IC card having an operation unit and a display unit must be used, and practical use is difficult in terms of cost, size, weight, and robustness of the IC card. Conceivable. In addition, if a plurality of persons are set and used on the operation unit and then left as they are, charges for the plurality of persons are collected even when one person passes the automatic ticket gate. In the thing shown by patent document 4, a group ticket must be issued with an automatic ticket vending machine for every number of groups, and there exists a problem that it cannot be used in the environment where an automatic ticket vending machine is not installed.

  An object of the present invention is to manage a person's entry into or exit from a management area by using a passage medium without providing an operation unit for inputting the number of people to pass, and a plurality of one passage medium. An object of the present invention is to provide a traffic management device that allows people to pass.

  In the traffic management device of the present invention, reading means for reading information recorded on a non-contact type traffic medium held over a communicable area, and whether or not the user of the traffic medium can pass based on the information read by the reading means A passability determining means that determines whether or not a user can open and close, a door that can be opened or closed to restrict or permit the passage of a user, a sensor that detects the passage of a user, and a sensor that is determined by the passability determination means. And a control unit that controls the opening and closing of the door so as to allow the detected user to pass. When the determination result for the passing medium is allowed to pass, the passing medium is placed in the communicable area. When it is continuously held over a plurality of times, the control means controls the opening and closing of the door so that the same number of persons can pass therethrough. Here, the sensor is a combination of the traffic detection sensor shown in the embodiment and the function of the control unit.

  In this way, a plurality of people can pass through the traffic management device using one traffic medium. As a result, for example, even if the outpatients who pass through the traffic management device consist of several groups, there is no need to issue a passing medium for each outpatient, and the labor and cost associated with issuing the passing medium are reduced. can do. In addition, since it is not necessary to provide an operation unit for inputting the number of people who pass through the traffic management device, the manufacturing cost of the traffic management device does not increase. Furthermore, the operation of holding the passing medium over the communicable area of the reading means multiple times does not take much time as compared with the operation of inputting the number of people in the operation unit as long as the number of times is less than the predetermined number, so there are many passers-by. Even at times, congestion in the traffic management device is prevented. For example, the number of outpatient groups entering a management area where admission of outpatients is restricted is generally up to about 5 people, and at most about 10 people. It can be done in a shorter period of time than inputting the number of people in the operation unit.

  In the embodiment of the present invention, when the determination result for the passing medium is allowed to pass and the passing medium is continuously held over the communicable area a plurality of times, the control means determines the number of times the holding is held. Can be displayed. In this way, since the number of times held is displayed, even if the actual communicable area that cannot be visually recognized is different from the communicable area assumed by the user of the traffic medium, the traffic management device recognized by the traffic management device You can know the number of times you hold your hand, that is, the number of people you can pass. Thus, the user holds the passing medium over the communicable area until the number of passing persons is displayed, so that the situation where the door is closed during passing can be prevented.

  In the embodiment of the present invention, the control means controls the opening and closing of the door so as to restrict the passage of the user when a predetermined time has elapsed after the passage is determined to be permitted, and the determination result for the passage medium is allowed to pass. In this case, when the traffic medium is continuously held over the communicable area a plurality of times, the control means can extend the predetermined time according to the number of times of the hold. By doing in this way, even if there are many people who pass and it takes time to pass, it is prevented that a door closes during passing. For example, when the number of times of holding is one, the predetermined time is set to 5 seconds, and when the number of times of holding is increased by one, it is extended by one second.

Further, in the embodiment of the present invention, the upper limit value of the number of persons permitted to pass when the passing medium is continuously passed over the communicable area is recorded in the passing medium. In the case where the result is passable, when the passable medium is continuously held over the communicable area a plurality of times, the control means only determines the smaller number of the passed times and the upper limit value. Controls opening and closing of the door so that people can pass through, and displays that the operation is valid for the number of operations that are less than or equal to the upper limit, and the operation for the operations that exceed the upper limit. Can be displayed to indicate that is invalid.
By doing in this way, the upper limit value of the number of people who can pass can be defined by holding one passage medium a plurality of times based on the operation status of the traffic management device. Further, the upper limit value does not need to be the same for all the traffic media, and the upper limit value can be adjusted according to the number of the traffic media. Further, since the fact that the holding operation at that time is valid or invalid is displayed according to the magnitude relationship between the number of times the passing medium is held and the above upper limit value, there is an actual communication area that cannot be visually recognized. Even if it is different from the communicable area assumed by the user of the traffic medium, the number of effective holding operations can be known. Thereby, the user can know the upper limit of the number of people who can pass. Alternatively, the passage medium is held over the communicable area until the same number of effective persons as the number of persons who pass is displayed. As a result, it is possible to prevent a situation in which the door is closed during traffic.

Further, in the embodiment of the present invention, the control means is set with an upper limit value of the number of persons allowed to pass when the passing medium is continuously passed over the communicable area, and the determination result for the passing medium If the passage medium is continuously passed over the communicable area a plurality of times, the control means will only allow the smaller number of persons between the number of times that the pass is held and the upper limit value. The door is controlled to open and close so that the operation is valid for the number of operations that are less than or equal to the upper limit, and the operation is performed for the operations that exceed the upper limit. It can be displayed that it is invalid.
By doing in this way, the upper limit value of the number of people who can pass can be defined by holding one passage medium a plurality of times based on the operation status of the traffic management device. In addition, according to the magnitude relationship between the number of times the passing medium is held and the above upper limit value, it is displayed that the holding operation at that time is valid or invalid. Even if it is different from the communicable area assumed by the user of the traffic medium, the number of effective holding operations can be known. Thereby, the user can know the upper limit of the number of people who can pass. Alternatively, the passage medium is held over the communicable area until the same number of effective persons as the number of persons who pass is displayed. As a result, it is possible to prevent a situation in which the door is closed during traffic.

  Furthermore, in the embodiment of the present invention, the above-described passing medium can be a passing medium that is carried and used by a person on a daily basis. Here, the traffic medium used everyday by a person is, for example, an employee card possessed and used by an employee who can freely enter a management area where entry of an outpatient is regulated. By passing such a daily carrying medium over the communicable area a plurality of times, the same number of persons can pass therethrough, so that it is not necessary to issue a traffic medium for a visitor or the like. Also, in such a case, with the consent of the employee, the employee will be accompanied by a visitor and enter the management area through the traffic management device, so that suspicious persons should be prevented from entering the management area. Can do. Furthermore, the upper limit value of the number of passable persons recorded in the passing medium can be adjusted according to the job title of the employee or the like. Such cards are not limited to employee cards, but are also used by employees who work in the management area and are used by registrants registered as persons who can enter the management area. It may be a person card.

  According to the present invention, since a plurality of people can pass through the traffic management device using one traffic medium, it is possible to reduce the labor and cost associated with issuing the traffic medium. In addition, since it is not necessary to provide an operation unit for inputting the number of people to pass in the traffic management device, the manufacturing cost does not increase, and congestion in the traffic management device due to the number input operation does not occur.

  Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of a traffic management device according to the present invention. 2A is a side view of the traffic management device, and FIG. 2B is a front view of the traffic management device. FIG. 3 is a block diagram showing an electrical configuration of the traffic management device. FIG. 4 is a block diagram showing an electrical configuration of a card reader used in the traffic management device. The traffic management device is installed at the entrance / exit of the management area 51 where entry of outsiders, outsiders, etc. (hereinafter collectively referred to as “foreigners”) is restricted. The management area 51 is partitioned by a partition wall 53 from a non-management area 52 where a visitor can freely enter.

  The traffic management apparatus includes a pair of main bodies 2a and 2b arranged in parallel, and card readers 21a and 21b are provided on the main bodies 2a and 2b, respectively. When entering the management area 51 or leaving the management area 51, a person who has the card reader 21 a, 21 b read the valid (regular) card 1 that is a non-contact type passage medium (hereinafter referred to as “passable”) A person) can pass through the passage 50 of the traffic management device. In FIG. 1, the top 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. In the card display portions 22a and 22b, according to the validity / invalidity of the card 1 read by the card readers 21a and 21b, respectively, a message (hereinafter referred to as an OK message) shown in FIG. A message (hereinafter referred to as an NG message) indicating the passage failure shown in (b) is displayed. In addition, a passage permission / inhibition display unit 27 is provided on the front surface of the main body 2, and symbols (for example, “◯” and “×”) indicating whether the passage 50 is permitted to pass are displayed. In the present embodiment, since the passage 50 can pass in both directions, the symbol “◯” indicating that the passage is allowed is displayed on both the passage permission / inhibition display portions 27 of the main bodies 2a and 2b.

  Doors 23a, 24a and doors 23b, 24b are provided on the passage 50 side of the main bodies 2a, 2b, respectively, so that they can be opened and closed, and the doors 23, 24 are normally open. In this state, when an invalid (unauthorized) card 1 user or a person who does not have the card 1 (hereinafter also referred to as an inaccessible person) attempts to enter the management area 51, the exit door 24 is shown in FIG. Closes as shown by arrow A. Further, when an inaccessible person tries to leave the management area 51, the door 23 on the exit side closes as shown by an arrow B in FIG. When entering, the lower side of FIG. 1 is the entrance side, and the upper side is the exit side. When leaving, the entrance and exit sides are the opposite of entry.

  Further, on the passage 50 side of the main bodies 2a and 2b, passage detection sensors 25 and 26 for detecting passersby are provided. The traffic detection sensors 25 and 26 are, for example, transmission type optical sensors, and a projector is attached to one main body 2a, and a light receiver is attached to the other main body 2b. 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 the passage of a person who cannot pass, the control unit 20 closes the door 24 on the exit side.

  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 23 and 24. That is, the control unit 20 controls the opening and closing of the doors 23 and 24. In addition, the control unit 20 displays the above-described symbol indicating whether or not traffic is allowed on the pass / fail display unit 27 according to the operation mode of the traffic management device.

  The card reader 21 itself used in the present invention is known and reads card information recorded on the non-contact type card 1 via the antenna coil of the card reader 21. Here, a method of reading card information from the card 1 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 / I that is a communication interface for the antenna coil 215, the transmission circuit 213 and the reception circuit 214 connected to the antenna coil 215, the CPU 210, the memory 211, and the control unit 20. An F circuit 212 is 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.

  The operation of the card reader 21 will be described with reference to FIG. The operation described below is the same in the second embodiment described later, and is 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 card detection flag which is a variable whose area is secured in the memory 211 (S1). Next, a card reading process is executed to read card information from the card 1 (S2).

  An outline of the card reading process will be described. The time required for the card reader 21 to read the card information from the card 1 is extremely short compared to the time during which the card 1 is held over the communicable area of the card reader 21. For this reason, in the card reading process, when the card information of the same card 1 is continuously read, only the card information read first is used, and the card information read after that is not used. ing. Further, in the ordinary card reading process, no special meaning is given to the number of times the card 1 is held over the communicable area. Therefore, even when the same card 1 is held over the communicable area several times, it is held for the first time. Only the card information read first is used, and the card information read when it is held over is not used.

  Note that the card 1 being held over the communicable area of the card reader 21 means that the card 1 is removed from the communicable area after being placed in the communicable area, and communicated after being placed in the communicable area again. Is out of the possible area. However, as will be described later, in the present invention, traffic management is performed based on the number of times the card 1 is held over the communicable area, so that the read card information is used every time the card 1 is held over the communicable area. I have to. For example, when the card 1 is held over the communicable area twice, two pieces of card information are used.

  In the card reading process, 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 215, and as a result, the magnetic field passing through the antenna coil 215 changes. When the card information is received from the card 1 held over the communicable area of the card reader 21 by transmitting the command (S12: YES), it is checked whether the card detection flag is 0 (S13). When the card detection flag is 0 (S13: YES), that is, when the card 1 is read for the first time after being placed over the communicable area, the card detection flag is set to 1 (S14), and the received card information Is written in the transmission buffer in which the area is secured in the memory 211 (S15), and the process returns to the main process.

  If the card detection flag is not 0 (is 1) (S13: NO), the previous read card information stored in the memory 211 is compared with the card information received this time, so that the same card as the previous card is obtained. It is checked whether information has been received (S16). When the same card information as the previous time is received (S16: YES), that is, when the same card 1 is continuously held over the communicable area, the card information of the card 1 has already been written in the transmission buffer (S15). Therefore, return to the main process without doing anything. When the received card information is different from the previously received card information (S16: NO), since the card information of the new card 1 is read, the received card information is written in the transmission buffer (S15), and the process returns to the main process. .

  If it is determined in S12 that the card information has not been received (S12: NO), that is, if the card 1 does not exist within the communicable area of the card reader 21, the card detection flag is set to 0 (S17). Return to the main process. In such a case, since the card detection flag is set to 0, when the card 1 is taken out of the communicable area of the card reader 21 and then put into the communicable area again, the card information of the same card 1 Is written to the transmission buffer (S13 to S15).

  After the card reading process (S2) is executed, the system waits for a predetermined time (for example, 100 milliseconds) (S3). The reason for waiting for the time is to prevent the same card information from being read a plurality of times when the card 1 moves in and out of the boundary of the communicable area due to the shaking of the card user's hand. Next, it is checked whether or not a card information transmission instruction is received from the control unit 20 (S4). If not received (S4: NO), the process returns to S2 and the card reading process is performed again. If received (S4: YES), it is checked whether there is card information to be transmitted to the transmission buffer (S5). If there is card information to be transmitted (S5: YES), the card information is read from the transmission buffer, transmitted to the control unit 20 (S6), and the process returns to S2. If there is no card information to be transmitted (S5: NO), the fact that there is no card information is transmitted to the control unit 20 (S7), and the process returns to S2.

  Next, an outline of the operation of the traffic management device according to the present invention will be described. Since the operation when entering and leaving is the same, the operation when entering will be described. Here, it is assumed that a person who can freely enter the management area 51 using the card 1, for example, an employee possesses the card 1 (employee card). When the employee holds the valid card 1 over the card reader 21 a to read the card information, the employee can enter the management area 51 through the passage 50 without closing the door 24 on the exit side. On the other hand, when the entrance-side traffic detection sensor 25 detects the passage of the inaccessible person while the doors 23 and 24 are open, the exit-side door 24 is closed to restrict (inhibit) the passage of the inaccessible person. That is, the control unit 20 performs opening / closing control of the door 24 so that the same number of people as the number of the read valid cards 1, that is, the number determined to be passable, can pass through the passage 50.

  When an employee enters the management area 51 with a person who does not have the card 1, for example, a visitor, the employee holds the card 1 over the card reader 21 as many times as the number of visitors. For example, when there are two outpatients, the card 1 is held over the card reader 21 three times. By passing three times, the number determined to be allowed to pass becomes 3, and an employee and two foreigners can pass through the traffic management device.

  Next, with reference to FIGS. 6-9, the detail of operation | movement of the traffic management apparatus at the time of entrance 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 two variables whose areas are secured in the memory 20b of the control unit 20, that is, the number of permitted persons and the permitted number of timers (S21).

  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 passage permission timer will be described. After a valid card 1 is read by the card reader 21a, if a card user such as an employee does not enter the management area 51 and returns to the non-management area 52, 1 is already added to the number of allowed traffic. As a result, inaccessible people will be able to enter. 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. This fixed time is managed by a traffic permission timer. Since the timer process is started every 100 milliseconds as described above, the above-described fixed time (5 seconds) is realized by setting 50 for the passage permission timer.

  Return to the description of the main process. After S21, the doors 23 and 24 on the entrance side and the exit side are opened (S22). Next, the card reader 21a is instructed to transmit the card information read from the card 1 (S23). Upon receiving this instruction, the card reader 21a transmits the read card information 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 (S24: NO), the card reader 21a is again instructed to transmit the card information read from the card 1 (S23). When the card information is received (S24: 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 apparatus) in the card information. It is checked whether it is card information (S25).

  If it is the card information of the invalid card 1 (S25: NO), an NG message (FIG. 8B) indicating that traffic is restricted (prohibited) is displayed on the card display unit 22a (S38), S23 Return to. If it is the card information of the valid card 1 (S25: YES), it is checked whether the received card information is different from the previously received card information (S26). If the card information is different (S26: YES), that is, if it is card information of a new card 1, 1 is set as the number of times of holding, which is a variable for counting the number of times the card 1 is held over the card reader 21a (S27). ). Next, an OK message (FIG. 8A) indicating that traffic is permitted is displayed on the card display unit 22a (S28), and 1 is added to the number of permitted traffic (S29). Further, the set value (50) is set in the passage permission timer (S30), and the process returns to S23. Therefore, when the card user tries to enter after 5 seconds, the door 24 on the exit side is closed. The opening / closing control of the door 24 will be described later.

  When the received card information is the same as the previously received card information (S26: NO), that is, when the same card 1 is continuously held over again, the upper limit check (S31) of the number of times of holding shown in FIG. 7 is performed. . Here, data used for checking the upper limit of the number of times of covering will be described. In addition to the card-specific information and the card number described above, the card 1 has data (hereinafter referred to as a card passable person upper limit value) that defines the upper limit of the number of persons that can pass when the card 1 is held over several times. It is recorded. Here, when the card passable person upper limit value is 0, it is assumed that there is no upper limit value (no limit) for the passable person number. In addition, when the number is a positive integer, up to that number can pass through the traffic management device.

  For example, a card 1 having a card pass limit of 1 cannot be used when an employee and a visitor enter together. If the card 1 with the maximum number of cards that can be passed is held over the card reader twice, the employee and one visitor can enter together. If the card 1 is held over the card reader three times, the employee and two foreigners can enter together. However, even if you hold it over four times, you can only enter up to three people. The memory 20b of the control unit 20 of the traffic management device also records data that defines the upper limit value of the number of people who can pass when the card is held over several times (hereinafter referred to as the device passable upper limit value). Yes. The upper limit value of the number of people who can pass through the device is only a positive integer, and the value has the same meaning as the upper limit of the number of people who can pass through the card. The maximum value of the positive integer is not particularly limited. However, for example, a value of about 5 to 10 is used as the maximum value of the positive integer because of the nature of the present invention.

  In the upper limit check of the number of times of holding shown in FIG. 7, it is checked whether or not the upper limit value of the passable number of people exists in the received card information (the above-mentioned upper limit value of the passable number of cards is a positive integer) (S41). . If the upper limit value exists (S41: YES), if the above-mentioned number of times of holding is smaller than the upper limit value (S42: YES), the return value is OK and the process returns to the main process. If the number of times of holding is greater than or equal to the upper limit value (S42: NO), the return value is set to NG and the process returns to the main process. If the received card information does not have an upper limit value of the passable number of people (S41: NO), if the number of times of holding is smaller than the upper limit value of the passable number of people set in the passage management device (S43: YES), a return value is set. Return to the main process as OK. If the number of times of holding is not less than the above upper limit value (S43: NO), the return value is set to NG and the process returns to the main process.

  Return to the description of the main process. If the return value from the cover count upper limit check (S31) is OK (S32: YES), 1 is added to the count (S33), and the OK message and the number of people allowed to pass are displayed as shown in FIG. 8 (c). The data is displayed on the card display unit 22a (S34). Here, the number of passable persons displayed is the same value as the number of times of holding. In addition, since the number of passable persons increases by 1 from the previous time, it can be seen that the operation of holding the card 1 was effective. That is, a display indicating that the holding operation is effective is displayed. Next, since the number of people allowed to pass is increased by one, 1 is added to the number of people allowed to pass (S35). Further, a value obtained by adding the additional number of people to the set value (50) is set in the passage permission timer (S36), and the process returns to S23. Here, the additional number of people is added because the time required for everyone to pass increases due to an increase in the number of passable people. The additional number of people is calculated by, for example, {(number of times of holding-1) × 10}. As a result, when the number of passable people is 3, the additional number of people is 20, so the value of the pass permission timer is 50 + 20 = 70, and the pass permission timer expires in 7 seconds.

  If the return value from the cover count upper limit check (S31) is NG (S32: NO), as shown in FIG. 8 (d), the OK message, the passable number, and the passable number are the upper limit values. The information is displayed on the card display unit 22a (S37). Here, the number of passable persons displayed is the same value as the number of times of holding, but the number of times of holding is a value smaller than the number of times the card 1 is held over the card reader. Further, since it is displayed that the number of passable persons is the upper limit value, or the number of passable persons does not increase even though the card 1 is held over, it can be understood that the operation of holding the card 1 was invalid. That is, a display indicating that the holding operation is invalid is displayed. Next, a value obtained by adding the additional number of people to the set value (50) is set in the passage permission timer (S36), and the process returns to S23.

  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 entrance-side traffic detection sensor 25 detects the traffic of a passerby (S51). 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 (S51: NO), the process proceeds to S55.

  When the passage of a passerby is detected (S51: YES), if the value of the permitted number of people is 0 (S52: YES), if the door 24 on the exit side is open, it is closed (S53), and the process proceeds to S55. 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 (S52: NO), if any of the doors 23 and 24 on the entrance side and the exit side is closed (S54), the process proceeds to S55. As a result, the passable person detected by the entrance-side traffic detection sensor 25 is allowed to pass.

  In S55, 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 (S55: NO), the process returns to the caller without doing anything. If the passage of a passerby is detected (S55: YES), if the value of the permitted number of people is not 0, 1 is subtracted from the permitted number of people (S56, S57), and the process returns to the caller. Here, the door 24 on the exit side is not closed even when the value of the permitted number of people is zero by subtraction. However, when the passage detection sensor 25 on the entrance side detects the passage of a person with the value of the permitted number of persons being 0, the door 24 on the exit side is closed (S52 to S53), and the passage of the inaccessible person is restricted. .

  Next, the timer process will be described. When the timer process is started, if the value of the traffic permission timer is not 0, 1 is subtracted from the traffic permission timer (S61, S62). If the value of the traffic permission timer becomes 0 as a result of the subtraction, 0 is set as the number of permitted traffic (S63, S64), and the process returns to the caller. Here, the door 24 on the exit side is not closed even if 0 is set as the number of persons permitted to pass. However, when the passage detection sensor 25 on the entrance side detects the passage of a person with the value of the permitted number of people being 0, the door 24 on the exit side is closed (S52 to S53). In other words, when the pass permission timer started when the valid card 1 is read by the card reader 21 expires, the user of the valid card 1 cannot pass through the traffic management device.

  A second embodiment of the present invention will be described. FIG. 10 is a plan view of the traffic management device of the present embodiment, and the same components are indicated by the same reference numerals as in the previous embodiment. In the previous embodiment, a traffic management device was provided at the entrance / exit of the management area 51 to manage entry into the management area 51 and exit from the management area 51. In the present embodiment, a traffic management device including the main bodies 2a and 2c is installed at the entrance of the management area 51, and the entrance to the management area 51 is managed. Further, a traffic management device comprising the main bodies 2b and 2c is installed at the exit of the management area 51 to manage exit from the management area 51.

  In the previous embodiment, the doors 23 and 24 are normally open, and the door 23 or 24 is closed when passage of a person who cannot pass is detected. On the other hand, in this embodiment, the doors 24a and 24c of the entrance passage 50a and the doors 23b and 23d of the exit passage 50b are normally closed. After the card reader 21a (or 21b) reads the valid card 1, if the detection sensor 25 (or 26) on the entrance side detects the passage of a passable person, the door 24a as shown by the arrow C (or arrow D). , 24c (or doors 23b and 23d). Then, after the detection sensor 26 (or 25) on the exit side detects the passage of the passable person, the doors 24a and 24c (or the doors 23b and 23d) are closed again. The doors 23a and 23c of the entrance passage 50a and the doors 24b and 24d of the exit passage 50b are always open, and are unnecessary doors in the present embodiment.

  Next, the details of the operation of the traffic management apparatus installed at the entrance of the management area 51 will be described by comparing with the flowchart of the previous embodiment. In S2 (FIG. 5) of the main process of the previous embodiment, the entrance-side and exit-side doors 23, 24 are opened. In this embodiment, the entrance-side doors 23a, 23c are opened and the exit-side door 24a is opened. 24c are closed. This is the difference in the main process. The cover count upper limit check (FIG. 7) is the same in both embodiments.

  FIG. 11 is a flowchart showing the traffic detection process and timer process of the present embodiment. The number of each step in FIG. 11 is a number obtained by adding 100 to the number of the corresponding step in the previous embodiment (FIG. 7). Hereinafter, differences from the previous embodiment will be described. First, in this embodiment, the doors 23a and 23c on the entrance side are always open. Therefore, if the doors 24a and 24c on the exit side are closed in S154, they are opened. This is different from S54. Secondly, in this embodiment, the doors 24a and 24c on the exit side are normally closed, so when S158 and S159 are added and 1 is subtracted from the number of permitted passages, the value of the permitted number of passages becomes 0. The side doors 24a and 24c are closed. Thirdly, S165 is added for the same reason, and the doors 24a and 24c on the exit side are closed when the value of the passage permission timer becomes zero.

  In the embodiment described above, a case in which an outpatient who does not have the card 1 passes through the traffic management device together with the employee by causing the card reader 21 to read the card 1 held by the employee by holding the card reader 21 a plurality of times. Although described, the present invention is not limited to this. For example, a card for entering and leaving the management area 51 may be prepared in advance for reception, and this card may be used by an employee, a visitor, or the like to enter or leave the management area.

  Further, in the above embodiment, the upper limit value of the number of persons who can pass by setting the card 1 over the card reader 21 is set in the memory 20b of the card 1 and the control unit 20, and the upper limit value is set for the card 1. Although the upper limit value set in the memory 20b is checked when it is not, the present invention is not limited to this. For example, the upper limit value may be set only for one of the card 1 and the memory 20b, or the upper limit value may not be set for both.

  Furthermore, in the above embodiment, the OK message and the number of people who can pass are displayed on the card display unit 22 provided in front of the card reader 21. Instead, a part of the top cover of the card reader 21 may be a display unit that lights up green and red, and green may be turned on instead of the above-mentioned OK message, and red may be turned on instead of the NG message. Good. In this case, when the valid card 1 with the maximum number of passable persons set to 2 is held over the card reader 21 four times, green lights for the first and second times, and red lights for the third and fourth times. To do. That is, when the first and second holding operations are valid when green is lit, the third and fourth holding operations are invalid when red and red.

  Furthermore, in the above embodiment, management of the usage history of the card 1 has not been described, but each time the card 1 is used, the card number recorded on the card 1 and the card 1 are held over the card reader 21. May be stored in the memory 20b of the control unit 20 as a set of data, and the usage history of the card 1 may be managed using the stored data. Thereby, for example, the number of visitors can be checked for each card holder.
