Description

  The present invention relates to a gate system that controls the entry and exit of people in a management area such as a building or room that restricts people who can enter and exit.

  2. Description of the Related Art Conventionally, a gate system that restricts the entry and exit of people in a management area such as a building or a room that restricts people who can enter and exit has been proposed. In the conventional general gate system, an electronic lock is attached to an entrance door of the management area. Usually, the door is closed and the electronic lock is locked. Identification information is registered for those who are permitted to enter and exit the management area (hereinafter referred to as authorized persons). The identification information is, for example, an ID or biometric information (features such as a face and a fingerprint). Readers that read identification information are installed on both sides of the management area door. The person who wants to enter and leave the management area can read the identification information before the door. The gate system compares the identification information read from the person who wants to enter / exit with the identification information of each registered permitter to determine whether the person who wishes to enter / exit is a permitter. If it is determined that the person is an authorized person, the electronic lock of the door is unlocked and the door is permitted to be opened and closed. That is, the permitting person who wants to enter and leave the room is permitted to enter and leave the room. Conversely, if it is determined that the person is not permitted, the locked state is maintained without unlocking the electronic lock of the door. That is, when the person who wants to enter / exit is a non-permitted person, entry / exit is not permitted.

Also, recently, a wireless communication medium having a wireless communication function storing an ID is allowed to be possessed by an authorized person, and when the authorized person moves to the vicinity of the entrance / exit, wireless communication using the vicinity of the entrance / exit of the management area as a wireless communication area A gate system has been proposed in which an apparatus (corresponding to the above-described reader) automatically obtains an ID from a wireless communication medium possessed by the person and determines whether or not the person is an authorized person. (See Patent Document 1). In this gate system, if the permitter possesses a wireless communication medium, it is not necessary to perform any special action when entering or leaving the management area. In addition, a gate system that determines whether or not a group of a plurality of people is allowed to enter and exit a management area at once is proposed (see Patent Document 2). This patent document 2 states that “if one person is allowed to enter the room, the whole group is allowed to enter”, “if one person is not allowed to enter the room, all the groups are not allowed to enter”, etc. A gate system that can perform various entrance / exit controls according to the security level by providing a function that can be set and a function that controls the entry and exit of people in the management area according to this setting is shown.

  However, conventional gate systems do not allow unauthorized persons to leave the controlled area when the permitted person leaves the controlled area, or to allow the disabled person to enter the controlled area, or vice versa. No consideration was given to companionship. In other words, in the conventional gate system, security is ensured on the assumption that there is no unauthorized person on the opposite side of the side where the authorized person is located across the door of the entrance and exit of the management area.

  In addition, when unlocking the electronic lock, to prevent the situation that there is a non-permitted person on the opposite side of the side where the authorized person is located across the door of the controlled area, for example, the managed area It is necessary to provide a structure for detecting that an unauthorized person has entered between the double doors. Therefore, as the configuration becomes complicated, the processing of the system also becomes complicated, and there is a problem that the cost for constructing the system is greatly increased. In addition, when double doors are used, it takes a long time to enter and exit the management area, which hinders the smooth passage of the permitter.

  An object of the present invention is to provide a gate system capable of sufficiently ensuring security and sufficiently suppressing an increase in cost for system construction.

  Another object of the present invention is to provide a gate system that allows a permitter to enter and exit smoothly in a management area.

  In order to solve the above problems, the gate system of the present invention has the following configuration.

(1) A reading means for reading the identification information from each medium located in the wireless communication area, with the periphery of the opening and closing body in the space on one side partitioned by the opening and closing body installed at the gate position as a wireless communication area
A first reading device having identification information output means for outputting the identification information read by the reading means;
Reading means for reading the identification information from each medium located in the wireless communication area, the periphery of the opening and closing body in the space on the other side separated by the opening and closing body as a wireless communication area, and
A second reading device having identification information output means for outputting the identification information read by the reading means;
Identification information storage means for storing identification information of each medium that permits passage of the gate position;
Identification of each medium output by the first reading device is acquired, and for each medium identification information acquired here, identification of a medium that permits passage of the gate position stored in the identification information storage means First determination means for determining whether the information is information;
Identification of each medium output by the second reading device is acquired, and for each medium identification information acquired here, identification of the medium that permits passage of the gate position stored in the identification information storage means Second determination means for determining whether the information is information; and
When the first determination unit and the second determination unit determine that all identification information is identification information of a medium that permits passage of the gate position, the opening / closing body is opened. A traffic control device having an opening and closing body control means for performing control to permit,
It has.

  In this configuration, the first reading device having a wireless communication area around the opening / closing body in the space on one side divided by the opening / closing body installed at the gate position is identified from each medium located in the wireless communication area. Read and output information. In addition, a second reading device having a wireless communication area around the opening / closing body in the space on the other side separated by the opening / closing body reads and outputs the identification information from each medium located in the wireless communication area. . The gate position is the entrance / exit of the management area, and the opening / closing body is installed at the entrance / exit of the management area, and is a door, a flap, or the like that restricts the entrance and exit of people in the management area. Further, the space on one side is a space outside the management area (or inside the management area), and the space on the other side is a space inside the management area (or outside the management area).

  In the first determination unit, the gate device determines whether or not the identification information that permits passage of the gate position stored in the identification information storage unit for each piece of medium identification information output from the first reader, that is, first It is determined whether each person located within the wireless communication area of the reading apparatus is a person who is permitted to pass the gate position. Further, in the second determination means, for each medium identification information output by the second reading device, whether or not the identification information permits passage of the gate position stored in the identification information storage means, that is, the second reading. For each person located within the wireless communication area of the device, a determination is made as to whether the person is permitted to pass through the gate. When the gate control means determines that all the identification codes are identification codes permitting passage of the gate position by the first determination means and the second determination means, the opening / closing body is opened. Control to allow that.

  That is, the gate device determines whether or not the person is a permitter for each person who wishes to enter the management area, for example, by the first determination means, and for example, from the management area by the second determination means. For each person who wants to leave the room, a determination is made as to whether the person is a permitter. Then, when it is determined that all the applicants for entering the room and those who want to leave the room are permitted, the electronic lock provided on the opening / closing body is unlocked by the opening / closing body control means, and the opening / closing body is opened. Allow. The opening / closing body may be a manual door that is opened and closed by a passerby who passes through the gate position, or may be an automatic door.

  In this way, when all of the person who wants to enter the room on one side of the opening / closing body and the person who wants to leave the room on the other side of the opening / closing body are permitters, the control for permitting the opening / closing body to be opened is performed. So, without allowing the double door to open and close (without complicating the configuration), when the permitter leaves the management area, the non-permitted person enters the management area from the opposite side or on the contrary When the permitter enters the management area, it is possible to prevent the unauthorized person from coming out of the management area from the opposite side. Therefore, it is possible to sufficiently secure security and sufficiently suppress an increase in cost for system construction.

(2) The traffic control device
The identification information of the medium determined to permit passage of the gate position by the first determination means or the second determination means, and the identification information of the medium determined to not allow passage of the gate position. A setting means for setting whether to allow the opening / closing body to be opened conditionally or not to allow the opening / closing body to be opened when mixed.
The opening / closing body control means is determined not to permit the passage of the gate position and the identification information of the medium determined to permit the passage of the gate position by the first determination means or the second determination means. Means for controlling whether to allow the opening / closing body to be opened conditionally or not to be opened based on the setting of the setting means when the identification information of the medium is mixed. is there.

  In this configuration, in the setting means, when a permitter and a non-permitted person are mixed among a plurality of persons who want to enter the room on one side of the opening / closing body, or a plurality of persons on the other side of the opening / closing body Permits the opening / closing body to be opened conditionally or disallows the opening / closing body to be opened when there are both permitted persons and non-permitted persons among those who want to leave the room Can be set. When a permitter and a nonpermitted person are mixed among a plurality of people who wish to enter the room on one side of the opening / closing body, the opening / closing body control means determines whether the opening / closing body is based on the setting of the setting means. Is controlled whether to open the opening conditionally or not to open the opening / closing body.

  For example, the setting means can set an identification code of an authorized person who may bring an unauthorized person to the management area. Opening / closing body control means. The identification code for which the first determination means has determined whether or not to permit passage of the gate position includes the identification code of the permitter that is set to be allowed to be accompanied, and the first If the identification code of the non-permitted person is included in the identification code that determines whether the determination means permits passage of the gate position, or conversely, whether the second determination means permits passage of the gate position Whether the identification code of the permitter that is set to be allowed to be accompanied is included in the identification code that has been determined whether or not the second determination means permits passage of the gate position When the determined identification code includes an unauthorized person identification code, the opening / closing body is permitted to be opened conditionally.

  Therefore, if for any reason you want to allow a disallowed person to enter or leave the controlled area, you can bring the disallowed person into or out of the controlled area by accompanying a permitted person who is allowed to take it with you. it can. As a result, it is possible to perform control related to entry / exit of the management area according to the operation status while ensuring sufficient security.

(3) Furthermore, an imaging device including an output unit that images the wireless communication area of the first reading device and outputs the captured image,
The traffic control device includes:
An image processing unit that acquires a captured image output by the imaging device and detects the number of passers-by located in the wireless communication area of the first reading device;
The opening / closing body control means has a number of passersby located in the wireless communication area of the first reading device detected by the image processing means, rather than the total number of identification information of the medium acquired from the first reading device. If there are many, it is a means to control whether to permit opening and closing of the opening / closing body is conditional or not based on the setting of the setting means.

  In this configuration, the imaging device captures an image of the inside of the wireless communication area of the first reading device. That is, the imaging device images a passerby (a person who wants to enter the room or a person who wants to leave the room) who wants to move from one side of the opening / closing body to the other side through the gate position. In the image processing means, the gate control device processes an image of a passerby (a person who wants to enter or leave the room) imaged by the imaging device, and detects the number of persons. Then, when the total number of passers-by obtained by processing images picked up by the imaging device is larger than the total number of identification codes read by the first reader, that is, the passer-by has no medium. When there is a person, control is performed to permit the opening / closing body to be opened conditionally or not to open the opening / closing body based on the setting of the setting means.

  Therefore, if an unauthorized person who does not own the media for any reason wants to enter or leave the controlled area, the authorized person may be allowed to enter or leave the controlled area without the media. it can. Thereby, entrance / exit control according to the situation can be performed while sufficiently securing security.

  In addition, an image pickup device for picking up an image of the wireless communication area of the second reading device is additionally provided, and an image picked up by the image pickup device is processed to move from one side of the opening / closing body to the other side. Comparing the number of passers who want to travel with the total number of identification codes read by the second reader, and moving to the other side from one side of the opening / closing body It may be determined whether or not there is a user who does not have the medium, and processing similar to the above may be performed according to the determination result.

(4) The opening / closing body control means of the traffic control device includes:
If there is no identification information determined by the first determination means and the second determination means that the medium is permitted to pass through the gate position, the opening / closing body is not permitted to be opened. Control is performed.

  In this configuration, when there is no authorized person, the opening / closing body is not permitted to be opened, so that the security is not lowered.

(5) The traffic control device
When the control for disabling the opening and closing of the opening / closing body is performed, an output means for outputting the reason is provided.

  For this reason, it is possible to notify the person around the opening / closing body of the reason why the opening / closing body is not permitted to open.

  According to the present invention, it is possible to sufficiently suppress the cost for system construction and operation without reducing the security for management of people entering and leaving the management area.

  In addition, permitters can enter and exit smoothly in the management area.

  Furthermore, entry / exit control according to the situation can be performed while ensuring sufficient security.

The locking / unlocking unit 22 detects the open / closed state of the door 7 based on the output of a sensor (not shown) that detects the open / closed state of the door 7 provided on the door 7. The transmission / reception unit 23 receives an instruction to lock or unlock the electronic lock 8 transmitted from the host device 1 or notifies the host device 1 of the open / closed state of the door 7.

  When the door 7 is configured as an automatic door, the locking / unlocking unit 22 unlocks the electronic lock 8 when the host device 1 instructs to unlock the electronic lock 8, and Open. When the host device 1 instructs to lock the electronic lock 8, the door 8 is closed and the electronic lock 8 is locked.

  FIG. 5 is a diagram illustrating a configuration of a main part of the reading device in the entrance / exit management system of this embodiment. The reading device 3 includes a control unit 31 that controls the operation of the main body, a wireless communication unit 32 that receives an ID transmitted from the wireless communication medium 9 located in the wireless communication area, and an ID received by the wireless communication unit 32. That is, a transmission unit 33 that transmits the ID read from the wireless communication medium 9 to the host device 1. The first wireless communication area of the entrance wireless communication device 3A is formed around the door 7 outside the management area. However, as shown in FIG. 1, a part has reached the management area. The second wireless communication area of the leaving wireless communication device 3A is formed around the door 7 inside the management area. However, as shown in FIG. 1, a part has reached the outside of the management area. That is, the first wireless communication area and the second wireless communication area overlap at the boundary between the management area and the outside of the management area. Each time the wireless communication unit 32 receives an ID from the wireless communication medium 9, the reading device 3 immediately transmits the ID received by the transmission unit 33 to the host device 1. The wireless communication medium 9 is configured to transmit an ID as a wireless signal at regular intervals, for example, every 1 s. Therefore, the reader 3 receives the ID from each wireless communication medium 9 located in the wireless communication area at regular time intervals.

  FIG. 6 is a diagram showing the configuration of the main part of the display device in the entrance / exit management system of this embodiment. The display device 4 displays a control unit 41 that controls the operation of the apparatus main body, a reception unit 42 that receives a display instruction transmitted from the host device 1, a message based on the display instruction received by the reception unit 42, and the like. A display unit 43. In the entry display device 4A, the display unit 43 is attached at a position that is easy for a person entering the management area to see. Specifically, the display unit 43 is attached around the door 7 in the management area and outside the management area. In addition, the display device 4B for leaving the room has the display unit 43 attached to a position that is easy to see for those who leave the management area. Specifically, the display unit 43 is attached around the door 7 in the management area and inside the management area.

  Next, operation | movement of the entrance / exit management system of this embodiment is demonstrated. FIG. 7 is a flowchart showing the operation of the reading device, FIG. 8 is a flowchart showing the operation of the electronic lock control device of this embodiment, and FIGS. 9 and 10 are flowcharts showing the operation of the host device of this embodiment. is there.

  When the wireless communication unit 32 receives the ID transmitted from the wireless communication medium 9 located in the wireless communication area (s1), the reading device 3 receives the ID received this time from the transmission unit 33 together with its own identification code. The data is transmitted to the host device 1 (s2), and the process is repeated. As described above, the wireless communication medium 9 is configured to voluntarily send an ID as a wireless signal at regular intervals. Therefore, when the wireless communication medium 9 exists in the wireless communication area, that is, when the person who owns the wireless communication medium 9 is in the wireless communication area, the reading device 3 repeats this processing at regular intervals. .

  Here, the wireless communication medium 9 is configured to transmit the ID spontaneously at regular intervals, but may be configured to transmit the ID in response to polling from the reading device 3. In this case, the reader 3 may be configured to perform polling at regular intervals.

  In addition, the reader 3 transmits the identification code of the own device together with the ID received by the wireless communication unit 32 to the host device 1 because the reader 3 that has transmitted the ID in the host device 1 reads the reading for entering the room. This is because it is possible to determine whether the device 3A or the reading device 3B for leaving the room.

  The electronic lock control device 2 locks the electronic lock 8 of the door 7 at the normal time. When the transmission / reception unit 23 receives an unlocking instruction for the electronic lock 8 from the host device 1 (s11), the locking / unlocking unit 22 unlocks the electronic lock 8 (s12). As a result, the door 7 can be freely opened and closed. After that, when the electronic lock control device 2 receives the locking instruction of the electronic lock 8 from the host device 1 in the transmission / reception unit 23 (s13), the door 7 is in a closed state or for a certain time from the reception of the locking instruction, for example, Wait for 5s to elapse (s14, s15). The electronic lock control device 2 detects the open / closed state of the door 7 based on the output of a sensor that detects the open / closed state of the door 7. When the electronic lock control device 2 detects that the door 7 has been closed before a predetermined time has elapsed, the electronic lock control device 2 locks the electronic lock 8 (s16), and returns to s11. On the other hand, the electronic lock control device 2 keeps the door 7 open for some reason without the door 7 being closed, that is, anyone can enter and leave the management area. It is determined that it is in a state, and error processing such as notifying this state to a security room or sounding an alarm is performed (s17). By performing the error processing related to s17, a response is promptly performed when the door 7 is held in an open state due to an unauthorized act or when the door 7 is held in an open state due to some failure. Can be made. The electronic lock control device 2 performs a recovery operation by a security guard after executing the error process in s17, and when the door 7 is closed (s18), the electronic lock 8 is locked (s19), and the process returns to s11. . The period from when the electronic lock control device 2 unlocks the electronic lock 8 at s12 to when the electronic lock 8 is locked at s16 is a period during which entry / exit in the management area is permitted.

  Next, the operation of the host device 1 will be described. At this time, the electronic lock 8 of the door 7 is locked. The host device 1 determines whether or not the wireless communication medium 9 is located in the first wireless communication area (s21). Specifically, the determination is made based on whether or not the ID of the wireless communication medium 9 transmitted from the entrance reader 3A is received. If the host device 1 determines that the wireless communication medium 9 is located in the first wireless communication area in s21, that is, if it is determined that there is a person who wants to enter the management area, It is determined whether there is an unauthorized person who is not permitted to enter or exit the management area (s22). In s22, for each ID transmitted from the room reading device 3A, it is confirmed using the permitter database 16 whether the ID is permitted to enter or leave the management area. The total number of IDs determined not to be permitted to enter or leave the management area is detected as the total number of unauthorized persons. Then, if the detected number of disallowed persons is 0, it is determined that there are no disallowed persons, and if it is 1 or more, it is determined that there are disallowed persons.

  When determining that there is a disallowed person in s22, the host device 1 determines whether or not to permit this disallowed person to enter the management area with a condition (s23). In s23, first, it is determined whether or not there is a permitted person among persons in the first wireless communication area, that is, whether or not all persons in the first wireless communication area are unauthorized persons. In this determination, if the total number of IDs received this time from the entrance reader 3A is equal to or less than the total number of non-permitted persons detected in s22, it is determined that there is no permitted person, and in other cases, there is a permitted person. To do. Here, the host device 1 determines that entry into the management area is not permitted if all the members are non-permitted. On the other hand, if there is a permitter, it is determined for each permitter whether or not to permit the unauthorized person to enter the management area with a condition based on the setting condition of the record registered in the setting condition database 17. To do. Specifically, the person who wishes to enter the room includes a permitted person who is allowed to be accompanied, and the current time is the date and time when the permitted person is allowed to be accompanied. In the case where the maximum number of persons allowed to be accompanied by a person is equal to or greater than the total number of non-permitted persons detected this time, it is determined that entry into the management area is permitted under certain conditions. In other cases, it is determined that entry is not permitted.

  If the host device 1 determines that there is no unauthorized person in s22, or if it is determined that entry is permitted with conditions in s23, whether or not the wireless communication medium 9 is located in the second wireless communication area is determined. Determine (s24). Specifically, the determination is made based on whether or not the ID of the wireless communication medium 9 transmitted from the reading device 3B for leaving the room has been received. If the host device 1 determines that the wireless communication medium 9 is not located in the second wireless communication area in s24, that is, if it is determined that there is no person who wants to leave the management area, the host device 1 The electronic lock 8 is instructed to be unlocked, and the display device 4A is instructed to display an entrance permission message (s25). The situation in s25 is a situation where there is a person who wants to enter the management area and there is no person who wants to leave the management area. In s25, if there is no disapproved person among those who wish to enter the room, an instruction is given to display a message such as “Please enter immediately” on the entry display device 4A. If there is a disallowed person, that is, if entry is permitted under certain conditions, a message such as “Mr. XX, 3 disallowed persons are accompanied” is displayed to the entry display device 4A. To do. As a result, it is possible to allow the authorized person who is allowed to be accompanied to recognize that the person is accompanying or the number of persons who are accompanied. Therefore, when there is a non-permitted person who is not recognized by the permitted person who is allowed to share, the permitted person can be recognized as such, and sufficient security can be ensured. Further, at this time, the host device 1 does not issue a display instruction to the display device 4B for leaving the room, but no problem arises because there is no person who wants to leave the room.

  If the host apparatus 1 determines in s24 that the wireless communication medium 9 is located in the second wireless communication area, that is, if it is determined that there is a person who wants to leave the management area, the host apparatus 1 Then, it is determined whether or not there is an unauthorized person who is not permitted to enter or exit the management area (s26). The determination concerning s26 is the same as s22 described above, and for each ID transmitted from the leaving reading device 3B, an ID that allows entry into and exit from the management area using the permitter database 16. In this confirmation, the total number of IDs determined not to be permitted to enter or leave the management area is detected as the total number of unauthorized persons. Then, if the detected number of disallowed persons is 0, it is determined that there are no disallowed persons, and if it is 1 or more, it is determined that there are disallowed persons.

  When determining that there is a disallowed person in s26, the host device 1 determines whether or not to permit the disallowed person to leave the management area with a condition (s27). The process related to s27 is the same as the process related to s23. First, whether or not there is a permitter among the persons in the second wireless communication area, that is, all persons in the second wireless communication area are not permitted. It is determined whether it was a person. Then, the host device 1 determines that leaving from the management area is not permitted if all the members are not permitted. On the other hand, if there is a permitter, for each permitter, it is determined whether or not to permit the unauthorized person to leave the management area with a condition based on the setting condition of the record registered in the setting condition database 17. To do.

  The host device 1 instructs the electronic lock control device 2 to unlock the electronic lock 8 when it is determined at s26 that there is no unauthorized person, or when it is determined at s27 that it is permitted to leave the room. The entry display device 4A is instructed to display an entry permit message, and the exit display device 4B is instructed to display an exit permit message (s28). The situation in s28 is a situation where there are people who want to enter the management area and those who want to leave. In s28, if there are no disapproved persons among those who wish to enter the room, display a message such as "Please enter the room promptly. If it is instructed to display on the display device 4A for entry, and there are disapproved persons among those who wish to enter the room, that is, if the entry is permitted under certain conditions, “Mr. Instruct the display device 4A to display a message such as “Be careful not to collide with someone who wants to leave the room on the other side.” Also, if there are no unauthorized persons among those who want to leave the room, a message such as “Please leave immediately. Please be careful not to collide because there is a person who wants to enter the room on the other side.” If it is instructed to display on the display device 4B and there is a disapproved person among those who want to leave, that is, if it is permitted to leave the room under certain conditions, "Mr. “Be careful not to collide because there is a person who wants to enter the room on the opposite side.”, The display device 4B is instructed to display the message. As a result, the authorized person who is allowed to be accompanied can recognize that the person is accompanied and the number of people who are accompanied, and the person who wishes to enter or leave the room on the opposite side. Therefore, it is possible to prevent the person who wants to enter the room and the person who wants to leave the room from colliding at the position of the door 7.

  The host device 1 continues to receive the ID transmitted from the reading device 3 while performing this process. As described above, the first wireless communication area and the second wireless communication area are set outside and inside the management area with the door 7 in the management area in between, and partly near the door 7. Are overlapping. For this reason, the person who enters the management area passes through the first wireless communication area and the second wireless communication area in this order. When the host device 1 receives the ID received from the entry reader 3A from the exit reader 3B, the person who owns the wireless communication medium 9 storing the ID has entered the management area. to decide. On the other hand, when the ID received from the room reading device 3B is received from the room reading device 3B, it is determined that the person who has the wireless communication medium 9 storing the ID has left the management area.

  The host device 1 has completed entry or exit of the person who has permitted the entry this time, and there are no other authorized persons or non-permitted persons in the first wireless communication area and the second wireless communication area ( In the following, the process waits until the lock is permitted (s29). Also at this time, the host device 1 receives the ID transmitted from the reading device 2 at regular intervals. When the host device 1 enters a state where no ID is transmitted from the reading device 2, the host device 1 determines that the lock is permitted. Further, the host device 1 detects an unauthorized person entering or leaving the management area until the lock is permitted (s30). As described above, the host device 1 receives the ID transmitted from the reading device 3 at regular intervals. In the received ID, if there is an ID other than the person who has permitted entry or exit in the previous process, it is determined whether this ID is an ID that allows entry into or exit from the management area. If the ID allows entry into and exit from the management area, entry into and exit from the management area is not restricted. On the other hand, if the ID is not permitted to enter or leave the management area, it is detected as an unauthorized person entering or leaving the room. When the host device 1 detects an unauthorized entry / exit in s30, the host device 1 performs error processing such as reporting to the security room (s32), and returns to s29. Thereby, when appropriate entry / exit is performed in the management area, it is possible to secure security against an unauthorized entry / exit entering the management area by using this opportunity of entry / exit. When the host device 1 determines that the lock is permitted in s29, the host device 1 instructs the electronic lock control device 2 to lock the electronic lock 8 (s31).

  If the host device 1 determines that the conditional exit is not permitted in s27, the host device 1 instructs the entry display device 4A to display an entry non-permission message, and the exit display device 4B does not leave the room. The display of the permission message is instructed (s33). At this time, the host apparatus 1 performs error processing for notifying the security room or the like of the situation that has occurred (s34). The situation in s33 is a situation where entry into the management area is permitted for those who wish to enter, but is not permitted for those who wish to leave. In s33, it is instructed to display a message such as “There is a person who wants to leave the room on the opposite side of the door 7. Please wait for a while.” on the display device 4A for entering the room. There is an unacceptable person in the room. Cannot leave the room "is displayed to the leaving display device 4B. As a result, the applicant who wishes to enter the room within the first wireless communication area can be notified of the reason for not being able to enter the management area. It can be notified that there are unauthorized persons. In s33, since the electronic lock 8 is not unlocked, unauthorized persons can be prevented from leaving the management area illegally, and sufficient security can be ensured. Further, when the processing related to s33 is completed, the host device 1 returns to s21 and repeats the above-described processing. Therefore, at this time, the unauthorized person in the second wireless communication area is outside the second wireless communication area. The reason why it is determined not to permit the conditional exit in s27, such as by moving to, is eliminated, or a security guard or the like who has received notification regarding error processing in s34 responds to the first wireless communication Those who wish to enter the area can enter the management area.

  If the host device 1 determines in s35 that the wireless communication medium 9 is located in the second wireless communication area, that is, if it is determined that there is a person who wants to leave the management area, the host device 1 It is determined whether or not there is an unauthorized person who is not permitted to enter or exit the management area (s36). The determination relating to s36 is the same as s22 and s26 described above, and entry / exit into the management area is permitted using the permitter database 16 for each ID transmitted from the exit reading device 3B. It is confirmed whether or not it is an ID, and the total number of IDs determined in this confirmation that entry into and exit from the management area is not permitted is detected as the total number of unauthorized persons. Then, if the detected number of disallowed persons is 0, it is determined that there are no disallowed persons, and if it is 1 or more, it is determined that there are disallowed persons.

  When determining that there is a disallowed person in s36, the host device 1 determines whether or not to permit this disallowed person to leave the management area with a condition (s37). The process related to s37 is the same as the process related to s23 and s27. First, whether or not there is an authorized person among the persons in the second wireless communication area, that is, all the persons in the second wireless communication area are all. Determine if you were an unauthorized person. Then, the host device 1 determines that leaving from the management area is not permitted if all the members are not permitted. On the other hand, if there is a permitter, for each permitter, it is determined whether or not to permit the unauthorized person to leave the management area with a condition based on the setting condition of the record registered in the setting condition database 17. To do.

  In addition, when the host device 1 determines to permit the conditional exit in s37, the host device 1 determines whether or not the electronic lock 8 may be unlocked (s38). The determination relating to s38 is canceled if entry to the controlled area under conditions is not permitted in s23, that is, if there is a person who is not permitted to enter the managed area in the first wireless communication area. It is determined that locking is not possible, and it is determined that unlocking is possible in other cases. If the host device 1 determines that the unlocking is possible in s38, the host device 1 instructs the electronic lock control device 2 to unlock the electronic lock 8, and instructs the display device 4B to display a leaving permission message ( s39). The situation in s39 is a situation where there is no person who wants to enter the management area and there is a person who wants to leave the management area. In s39, if there is no disapproved person among those who want to leave, it is instructed to display a message such as “Please leave immediately” on the display device 4B for leaving, If there is a disallowed person, that is, if you are allowed to leave the room under certain conditions, instruct the display device 4B to display a message such as “Mr. To do. As a result, it is possible to allow the authorized person who is allowed to be accompanied to recognize that the person is accompanying or the number of persons who are accompanied. Therefore, if there is a non-permitted person who is not recognized by the permitted person who is allowed to share, the permitted person can be recognized as such, and sufficient security can be ensured. At this time, the host device 1 does not issue a display instruction to the entry display device 4A. However, since there is no person who wishes to enter the room, there is no particular problem. When the processing related to s39 is completed, the host device performs the processing after s29.

If the host device 1 determines that unlocking is not possible in s38, the host device 1 instructs the display device for exit 4B to display an exit disapproval message (s40). In s40, if necessary, the entry display device 4A is also instructed to display an entry non-permission message. At this time, the host device 1 performs error processing for notifying the security room or the like of the situation that has occurred (s41). The situation at s40 is
(1) There is no applicant for entry, and the person who wants to leave is not allowed to leave. (2) The person who wants to enter the room is not allowed to enter, and the person who wants to leave is allowed to leave. ) Anyone who is not allowed to enter the room who wants to enter the room and who is not allowed to leave the room.

  In the situation of (1) above, the host device 1 instructs the display device 4B to display a message such as “There are non-permitted persons among those who want to leave. At this time, the display device 4A for entering the room is not instructed to display an entry non-permission message. Also, in the situation of (2) above, it is instructed to display a message such as “There are unauthorized persons among those who wish to enter the room. Instruct the exit display device 4B to display a message such as “There is an applicant who is not allowed to enter the room on the opposite side of 7. Please wait.” Furthermore, in the situation of (3) above, it is instructed to display a message such as “There are unauthorized persons among those who wish to enter the room. A message such as “There is a disapproved person among the applicants. Cannot leave.” Is displayed to the exit display device 4B.

  Further, when the processing related to s41 is completed, the host device 1 returns to s21 and repeats the above-described processing, so that an unauthorized person in the first wireless communication area at this time is outside the first wireless communication area. The reason why it was determined not to permit conditional entry in s23 is resolved (in the case of (2) above), or a security guard who has received notification regarding error processing in s41 By responding, a person who wants to leave the room in the second wireless communication area can leave the management area.

  In the above embodiment, even if a non-permitted person properly entering the management area due to the permission of the authorized person, the person cannot leave the management area without the permission of the authorized person. An entry / exit history database in which the history of entry / exit in the management area is registered is stored in the storage unit 12, and when leaving the room, an error process such as reporting to the security room is performed if the ID is accompanied by the permitter. It may not be. In this way, it is possible to prevent an unnecessary report from being made to the security room, and it is also possible for one unaccompanied person who has entered the management area to be withdrawn alone.

  Further, in the above embodiment, the host device 1 performs the error process for notifying the security room or the like when it is determined that the conditional entry is not permitted or the conditional ambassador Yutsu is not permitted. The error processing may not be performed. If the configuration does not perform error handling in this case, when an unauthorized person who does not intend to enter the management area passes through the first wireless communication area, an unnecessary report is sent to the security room in the security room. Can be prevented. However, if error processing is performed, it is possible to quickly catch unauthorized persons who illegally enter the management area and unauthorized persons who illegally enter the management area, thereby improving security.

  Furthermore, since the entrance / exit system of this embodiment can enter / exit a plurality of persons at once, smooth passage can be realized. In addition, when the permitter leaves the management area, the unauthorized person may enter the management area, or when the permitter enters the management area, the unauthorized person may leave the management area. Can be prevented. Moreover, it is not necessary to make the door 7 of the management area into a double structure, and the cost increase for system construction can be sufficiently suppressed.

  Next, another embodiment of the present invention will be described. FIG. 11 is a diagram showing a configuration of an entrance / exit management system according to another embodiment. The entrance / exit management system of this embodiment is different from the above-described embodiment in that an entry imaging device 5A for imaging the first wireless communication area and an exit imaging device 5B for imaging the second wireless communication area are added. . Other configurations are the same as those in FIG. 1, and the same components as those in FIG. The entrance imaging device 5 </ b> A inputs an image of the first wireless communication area being imaged to the host device 1. In addition, the imaging device 5B for leaving the room inputs the image of the second wireless communication area being imaged to the host device 1.

  In this embodiment, the entrance imaging device 5A and the exit imaging device 5B are provided, but only one of the imaging devices may be provided. In this case, from the viewpoint of security, it is desirable to provide the entrance imaging device 5A. In general, it is more effective to increase the security to prevent unauthorized persons from entering the controlled area than to increase the security to prevent unauthorized persons from leaving the controlled area illegally. Because is big.

  Further, this embodiment is different from the above embodiment only in the operation of the host device 1, and the operations of the electronic lock control device 2, the reading device 4, and the display device 5 are the same as those in the above-described embodiment. The entrance imaging device 5 </ b> A and the exit imaging device 5 </ b> B transmit the captured image to the host device 1 in synchronization with the timing at which the reading device 4 transmits the ID to the host device 1. The host device 1 includes an image processing unit 14 as shown in FIG. The image processing unit 14 is configured to process the captured image input from the imaging device 5 and detect the number of people captured in the captured image. For example, a person's face, torso, legs, and the like are cut out from the captured image by pattern matching, and processing is performed to detect the number of people being picked up from the total number of cut faces, torso, legs, and the like.

  Hereinafter, the operation of the host device 1 in the entrance / exit management system of this embodiment will be described. 13 and 14 are flowcharts showing the operation of the host device of this embodiment. In FIG. 13 and FIG. 14, the same step number is attached | subjected about the same process as the process demonstrated in FIG. 9 and FIG. When the host device 1 detects that the wireless communication medium 9 is located in the first wireless communication area in s21, the host device 1 processes the captured image captured by the entrance imaging device 5A and performs the first wireless communication. The number of people who want to enter the room is detected (s51). Then, it is determined whether there is an unauthorized person in the first wireless communication area (s52). The difference between the process related to s52 and the process related to s22 described above is that the number of persons detected in s51 is set as the number of persons who want to enter the room. That is, it is possible to detect a non-permitted person who does not have the wireless communication medium 9 in the first wireless communication area.

  In step s23, the host device 1 determines whether or not to permit entry of a disallowed person with a condition. If the host device determines that the passage of the unauthorized person is permitted with conditions in s23, the host device processes the captured image captured by the exit imaging device 5B, and whether there is a person in the second wireless communication area, and The number of persons is detected (s53). That is, in s53, the number of persons who want to leave is detected by processing the captured image captured by the exit imaging device 5B. If the number of persons detected in s53 is 0, that is, if there is no person in the second wireless communication area, the processes after s25 are performed. If the host device 1 determines that there is a person who wants to leave the room in s53, the host device 1 determines whether there is a disallowed person in the second wireless communication area in s54 (s54). The difference between the process related to s54 and the process related to s26 described above is that the number of persons who want to leave is set as the number of persons detected in s53. That is, it is possible to detect a non-permitted person who does not have the wireless communication medium 9 in the second communication area. When the host apparatus 1 performs the process related to s54, the host apparatus 1 performs the processes after s27.

  If the host device 1 determines that there is no person who wishes to enter the room at s21 or does not permit entry with a condition at s23, the host device 1 performs the process according to s34, and the wireless communication medium 9 is placed in the second wireless communication area. If is not located, the process returns to s21. If it is determined in s21 that the wireless communication medium 9 is located in the second wireless communication area, the captured image captured by the exit imaging device 5B is processed to detect the number of people who want to leave (s55). . Then, it is determined whether there is an unauthorized person in the second wireless communication area (s56). The difference between the process related to s56 and the process related to s36 described above is that the number of persons detected in s55 is set as the number of persons who want to enter the room. In other words, an unauthorized person who does not have the wireless communication medium 9 in the second wireless communication area can be detected. When the host apparatus 1 performs the process related to s56 and then performs the process related to s37, when it is determined in this s37 that the conditional exit is not permitted, the host apparatus 1 performs the field process after s40.

  On the other hand, if the host device 1 determines in s56 that there is no non-permitted person or that it is permitted to leave in condition in s37, the host device 1 processes the picked-up image picked up by the image pickup device 5A for entry and the number of people who want to enter Is confirmed to be 0 (s57). In s57, it is confirmed whether or not an unauthorized person who does not have the wireless communication medium 9 is in the first wireless communication area. When the host apparatus 1 detects that there is no person who wants to enter the room in s57, the host apparatus 1 performs the process after s38, and when it detects that there is a person who wants to enter the room in s57, the host apparatus 1 performs the process after s40.

  Thus, in this embodiment, while having the same effect as the system of the above embodiment, an unauthorized person who does not have the wireless communication medium 9 by using the imaging device for entry 5A and the imaging device for exit 5B. Since it is possible to detect a person who wants to enter the room and a person who wants to leave the room, the security can be further improved.
