Description

  The present invention relates to an entry / exit management method and apparatus, for example, an entrance / exit management method for managing a person entering or leaving an important management area having an entrance door that is clearly partitioned and locked from other areas for security reasons or other reasons. And device.

  If you are in a specific location (hereinafter referred to as a controlled area) that manages or manufactures information or equipment related to trade secrets that are trade secrets or confidential information, strictly control who has access to the controlled area (ie, entering and leaving the room). There is a need to restrict or manage and make only pre-authorized people accessible.

  For this purpose, the entire management area is closed, and one or a small number of doors (entrance doors) locked by, for example, electric locks, which can be entered and exited, are provided, and keys or IDs given to authorized persons from this door are provided. It is common to use a card to enable entry and exit. Of course, it is necessary to strictly manage such keys and ID cards so that they are not easily counterfeited or misused. In addition, it is necessary to always have a plurality of visitors (that is, two or more people) to enter the management area to prevent leakage of secrets and other accidents caused by one malicious visitor.

  The prior art in such technical fields is disclosed in several technical documents. After the first operator inputs the operator data to the operation device installed outside the management area, the second operator inputs the operator data within a certain period of time to authenticate the operator. An entrance / exit management system for unlocking a door is disclosed (for example, see Patent Document 1).

  In addition, when entering and leaving the entrance area to the monitoring area locked with an electric lock, a plurality of operation devices are provided, and it is confirmed that individual information registered in advance is input to both of these operation devices. Thus, a management system is disclosed that unlocks and allows entry into the monitoring area from the entrance door (see, for example, Patent Document 2).

Japanese Patent No. 3548693 (6th page, FIG. 3) JP 11-141233 A (page 3-5, FIGS. 1 and 2)

  However, the prior art as described above has a problem that it is impossible to perform reliable entrance / exit management. That is, in the entrance / exit system disclosed in Patent Document 1, when the management area is unmanned, for example, using an ID card obtained illegally (or forged), two IDs are obtained from the first controller. If the card is read, even one person can easily enter the management area. Also, when the user exits, the second controller may be allowed to read the first ID card and then the second operator may be allowed to read another ID card within a certain time. On the other hand, even in the management system disclosed in Patent Document 2, one operator with malicious intent can unlock and enter the monitoring area by inputting two pieces of individual information from each controller. . Therefore, in these prior arts, there is a problem that the reliability of allowing only a predetermined person to enter a management area under predetermined conditions is not sufficient.

  The present invention has been made in view of the above-described problems of the prior art, and a main object thereof is to provide an entrance / exit management method and apparatus that manages (limits) entrance / exit into a management area with higher reliability. .

  In order to solve the above-described problems, the entrance / exit management method and apparatus according to the present invention employs the following characteristic configuration.

(1) In order to prevent only one person from entering an important management area clearly separated from other areas by providing an entrance door with an electric lock , at an interval that cannot be accessed by one person at the same time. In an entrance / exit management method for managing entrance / exit to the management area in accordance with an operation to the first and second operating devices arranged ,
An unmanned state confirmation step for confirming whether or not the management area is unmanned, and when the management area is unattended, an operator confirmation medium that is brought close to the first and second operating devices. And an operator confirmation step for confirming whether or not a previously authorized person has operated each of the first and second operators simultaneously by reading with the second operator and the unmanned state confirmation step, respectively. A first unlocking step of unlocking an electric lock of the entrance door of the management area based on a result of the confirmation of both the confirmation and the confirmation by the operator confirmation step; and When it is confirmed by the confirmation that there is already a person in the management area, it is confirmed whether any one of the first and second operating devices is a permitted person in advance. Said A second unlocking step for unlocking the air lock; a reading for bringing the operator confirmation medium closer to the first and second operation devices; and the operator confirmation medium from the first and second operation devices. A timing instructing step for instructing a plurality of timings to be separated, and confirming whether or not the reading and releasing have been performed within a predetermined time from the reading and releasing timing instructed in the timing instructing step. An entry / exit management method comprising a reading / leaving time confirmation step .

  According to the entry / exit management method and apparatus of the present invention, the following remarkable effects in practical use can be obtained. In other words, when the management area is unattended, the entrance door electric lock is unlocked only when a plurality of (for example, two) pre-registered operators operate the operation devices arranged sufficiently apart from each other. Thus, since a plurality of operators are permitted to enter the room, it is possible to reliably prevent only one person from entering the room. Furthermore, each controller instructs the operator to read / release the operator confirmation medium such as an IC card at least once and monitors the actual read / release operation timing. Exit management becomes possible.

  Hereinafter, the configuration and operation of a preferred embodiment of an entrance / exit management method and apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

  First, FIG. 1 is a schematic configuration diagram of an entrance / exit portion to a management area which is a main part of an entrance / exit management device according to the present invention. In the management area (not shown), there is provided a management area entrance door 10 in which only authorized persons can enter and leave the room. The management area entrance door 10 is locked by, for example, an electric lock 12 and is configured such that it can be unlocked and entered / exited only when a specific authorized person is permitted. A first operating unit 20 and a second operating unit 30 that are IC card readers are installed on both sides of the management area entrance door 10 at intervals that cannot be accessed by one person at the same time.

  Next, FIG. 2 is a system configuration diagram showing the configuration of the entrance / exit management device according to the present invention. The entrance / exit management device for the management area includes an electric lock 12 provided at the management area entrance door 10, the door opening / closing detection means 14, a first operation device 20, a second operation device 30, and the first and first operation devices. The control units 21 and 31 are respectively connected to the two operation devices 20 and 30, and the monitoring server 40 is connected to the control units 21 and 31 via a LAN (local area network) 50.

  Here, the first operating unit 20 and the second operating unit 30 are preferably ICs arranged at a sufficient distance (that is, an interval that cannot be accessed simultaneously by one person) on both the left and right sides of the management area entrance door 10. It is a card reader. As will be described later, a display unit is provided for instructing the operator on the operation procedure visually (display) or audibly (voice). In addition, the monitoring server 40 includes a collation data storage unit 41 that preliminarily stores collation data for collation and authentication with an IC card or the like that is an operator confirmation medium input from the operation devices 20 and 30, a management area The number of people who have entered the room is subtracted from the number of people who have left the room, and the number of people entering the room is checked and stored, and a CPU (Central Processing Unit) 43 that is a controller that performs various controls. Contains.

  Next, with reference to the flowchart of FIG. 3, the preferred implementation of the method for managing entry / exit to the management area according to the present invention, which is the overall operation of the management apparatus for entering / exiting the management area according to the present invention shown in FIGS. An example will be described. First, the number of people in the management area of the monitoring server 40 determines whether the number of people in the management area is zero, that is, whether the management area is unattended (step S1). In the case of unattended (step S1: Yes), it is determined whether or not there is an input by the operator in both the first operating device 20 and the second operating device 30 (step S2). When there is an input for both the first controller 20 and the second controller 30 (step S2: Yes), it is determined whether the operator data of the first controller 20 is permitted to enter the room. The data input to the operating device 20 is sent to the monitoring server 40 via the control unit 21 and checked by the matching data 41 in the monitoring server 40 and the CPU 43 (step S3). If the operator of the first controller 20 is a room permitter (step S3: Yes), it is determined whether the operator of the second controller 30 can enter the room in the same manner as described above. (Step S4). And when it is confirmed that the operator of the 2nd operation device 30 is also an entry permission person (step S4: Yes), the electric lock 12 provided in the management area entrance door 10 is unlocked (step S5). ). Thereby, two persons, the operator of the first operating device 20 and the operator of the second operating device 30 can enter the room.

  On the other hand, when the 1st operation device 20 and the 2nd operation device 30 are not input simultaneously (step S2: No), when the operator of the 1st operation device 20 is not a person permitted entry (step S3: No). Alternatively, if the operator of the second controller 30 is not a person who has been permitted to enter the room (step S4: No), the process returns to the above-described step S2, and simultaneous input (that is, normal operation) of both the controllers 20 and 30. Wait for input by the user).

  When the management area is not unattended, that is, when two or more people have already entered the management area (step S1: No), it is determined whether or not there is an input to the first controller 20 (step S6). ). Then, it is determined whether or not the operator of the first controller 20 is a person permitted to enter the room by sending data input from the control unit 21 to the monitoring server 40 (step S7). When the operator of the first operating device 20 is a person who is permitted to enter the room (step S7: Yes), the electric lock 12 provided in the management area entrance door 10 is unlocked and the first operation is performed. The operator of the vessel 20 is allowed to enter the room (step S5). That is, since there are already two or more people in the management area, the operator of the first controller 20 is allowed to enter the room alone, and there are a total of three or more people in the management area. On the other hand, when the operator of the first controller 20 is not a room entry permitter (step S7: No), the process returns to the above-described step S6, and the person permitted to enter the room operates the first controller 20. wait.

  On the other hand, if there is no input from the first operating device 20 described above (step S6: No), it is determined whether there is an input from the second operating device 30 (step S8). If there is an input from the second operation device 30 (step S8: Yes), it is determined whether or not the operator of this operation device 30 is a room entry permitter (step S9). If the person is a room entry permitter (step S9: Yes), the electric lock 12 of the management area entrance door 10 is unlocked to allow entry into the management area (step S5). That is, since there are already two or more people in the management area, the operator of the second controller 30 is allowed to enter the room alone. If the operator of the second controller 30 is not a room entry permitter (Step S9: No), the process returns to Step S6 described above and waits for input from the first controller 20.

  Next, FIG. 4 is a timing chart for explaining the operation of the management device for entering and leaving the management area according to the present invention when the management area is unattended. 4, (a) shows the input operation timing of the first operating device 20, (b) shows the input operation timing of the second operating device 30, and (c) shows the authentication operation timing of the monitoring server 40.

  4 (a) and 4 (b), the hatched portion indicates a state in which an input operation has been performed on the respective operation devices 20 and 30. That is, there was an input to the first controller 20 at time t1, and it was input to the second controller 30 at time t2. Therefore, the monitoring server 40 performs an authentication operation of the input data to each of the operating devices 20 and 30 from time t2 input to both the first operating device 20 and the second operating device 30 at the same time. Then, the authentication operation by the monitoring server 40 is completed at time t3.

  Next, with reference to FIG. 5 and FIG. 6, the card reading operation by the first operating device 20 and the second operating device 30 will be described. As shown in FIG. 5, the first operating device 20 and the second operating device 30 are arranged on both the left and right sides of the management area entrance door 10 so as to be sufficiently separated from each other. Therefore, even if a malicious third party 29 holds two IC cards 25a and 25b in both hands, it tries to input (or access) the first operating unit 20 and the second operating unit 30. However, it is impossible to input these IC cards 25a and 25b to the first operating device 20 and the second operating device 30 simultaneously. Here, it is assumed that the first operating device 20 and the second operating device 30 have substantially the same configuration.

  Further, to input the IC cards 25a and 25b to the first operating device 20 or the second operating device 30, it is performed in accordance with an instruction as shown in FIG. The operation device 20 includes a display device 22 such as an LCD (liquid crystal display device), for example, a pair of LEDs (light emitting diodes) 23 and an IC card reading unit 24.

  First, when a person who wants to enter the management area approaches the management area entrance door 10, it is detected by a detection means (not shown) such as an infrared detector. Then, as shown in FIG. 6 (A), the message “Please read the card” is displayed on the display 22 of the controller 20. If necessary, voice may be used instead of this message or together with the message. When the IC card 25 is placed in front of the IC card reading unit 24 in accordance with the instruction of the display device 22, one of the pair of LEDs 23 is turned on to indicate that the IC card 25 is being read.

  When the reading of the IC card 25 is completed, a message “Please release the card” is displayed on the display 22 as shown in FIG. 6B. When the IC card 25 is separated from the IC card reading unit 24 in accordance with the instruction, the other of the pair of LEDs 23 is turned on. This indicates that the controller 20 has successfully read the data on the IC card 25 (the data input by the controller 20 is sent to the monitoring server 40 described above and performs an authentication operation). That is, the operator of the operating device 20 must perform an input operation of the IC card 25 at an appropriate timing in accordance with an instruction displayed on the display device 22 of the operating device 20.

  Next, the timing of the input operation of the IC card 25 by the first operating device 20 and the second operating device 30 and the authentication operation by the monitoring server 40 will be described with reference to the timing chart of FIG. FIG. 7A shows an instruction by the display 22 of the first operating device 20, particularly an instruction timing for separating the IC card 25 from the IC card reading unit 24. (B) shows the data input operation timing by the IC card 25 of the first controller 20. (C) shows the timing of an instruction to release the IC card 25 from the second controller 30. (D) shows the timing at which the IC card 25 is input to the IC card reader 24 of the second controller 30. And (e) shows the timing of the authentication operation | movement of the operator by the monitoring server 40. FIG.

  The operator of the first controller 20 starts his input operation by applying his IC card to the IC card reading unit 24 at time t1, and is given after an instruction to release the IC card 25 at time t3. The IC card 25 is separated from the IC card reading unit 24 at time t6 which is within time T. On the other hand, at time t2 after time t1, the operator of the second operating device 30 touches his IC card 25 against the IC card reading unit and after time t3 when an instruction to release the IC card is given to the display. At time t4, the IC card 25 is separated from the IC card reading unit. In this specific example, the instruction to release the IC card of the second operating device 30 (FIG. 7A) is issued simultaneously with the instruction to release the IC card of the first operating device 20 (FIG. 7C). However, the instruction from the second operating device 30 disappears at time t5 earlier than the instruction from the first operating device 20.

  As described above, after an instruction to release the IC card of the first controller 20 is issued, by managing the time T when the operator actually releases the IC card 25, unauthorized access can be prevented more reliably. Note that there is. Then, at time t6 after confirming that the operators of the first operating device 20 and the second operating device 30 have operated the respective IC cards at an appropriate timing, the authentication operation by the monitoring server 40 is started. .

  Next, another embodiment of the IC card reading operation will be described with reference to FIG. In this specific embodiment, both the first operating device 20 and the second operating device 30 read instructions for two cycles (or twice) (that is, an IC card) before the authentication operation by the monitoring server 40 is started. Is applied to the IC card reading unit 24) and a release instruction (operation to release the IC card from the IC card reading unit 24) is performed. Furthermore, after switching from the reading instruction to the instruction to release, the time until the IC card is actually released from the IC card reading unit 24 and the time until the IC card 25 is actually applied to the IC card reading unit 24 from the IC card reading instruction Is limited in advance. That is, it is determined whether the times T1, T2, and T3 shown in FIG. 8B and the times T4, T5, and T6 shown in FIG. 8D are within a predetermined time. Then, only when these times T1 to T6 are within the specified time, the monitoring server 40 performs an authentication operation of the operator.

  By this timing management, only those who are familiar with this data entry operation are allowed to enter the management area, and even more malicious third parties can enter the room, and if the management area is unattended, only one person can enter the room more reliably. It is possible to shut out.

  The configuration and operation of the preferred embodiment of the method and apparatus for entering and leaving the management area according to the present invention have been described in detail. However, it should be noted that such examples are merely illustrative of the invention and do not limit the invention in any way. Those skilled in the art will readily understand that various modifications and changes can be made according to a specific application without departing from the gist or spirit of the present invention.

  For example, the medium for inputting data to the first operation device and the second operation device is not limited to the above-described IC card, and data input such as a magnetic card, a personal identification number, fingerprint and other biometric authentication is possible. is there. It is also possible to provide three or more operating devices to increase the number of people entering the management area to three or more. In addition, an alarm will be provided so that if a malicious third party detects that a third party is attempting to enter the controlled area, it will notify the security guard, the security company or the nearest police station by voice or other means. It may be.
