[0024]
Next, the operation | movement which concerns on the said structure is demonstrated with reference to the flowchart of FIGS. 9-13 which mainly shows the control operation of the control part 7. FIG. In this embodiment, room entry management is performed by two-person verification, and the passage of the revolving door 1 is controlled by performing an anti-passback check. In addition, when entering the main room Cm, the ID discrimination results of both the card readers CR3 and CR4 are OK, and only the person who has pressed the IN button CRc discriminates the ID by the fingerprint reader B1, and the other person ID by the retina reader B2. As a result, you can enter the room only when it is OK. At this time, an anti-passback check is performed. When two people enter the room, the racks RA and RB are unlocked. When one person enters the room, only the rack RA is unlocked. Furthermore, one person can leave the main room Cm by the card reader CR3. Of course, an anti-passback check is also performed.
[0025]
First, the passage of the revolving door 1 will be described. In FIG. 9, the passer's ID card is read by the card reader CR1 (step S1), and if the ID number is OK, whether or not the front room flag for the anti-passback check of the passer is set. When the determination is made (steps S2 to S3) and the front chamber flag is set, the rotary door 1 is unlocked for ¼ turn in the direction in which the lock is inserted, and the OK lamp of the indicator lamp CRb is primarily lit. (Steps S4-S5). If the front room flag is not set, the NG lamp of the indicator lamp CRb is primarily turned on (step S6).
[0026]
When the revolving door 1 is rotated within a predetermined time, the front room flag of the passerby who has read the card reader CR1 is set (indicating that the front room Cb is not gone out) (steps S7 to S8). ). If NO is determined in steps S1, S3, and S7, the process proceeds to step S9, where it is determined whether or not the card reader CR2 is read. If not, the process returns to step S1. If it is read, the process proceeds to step S10 shown in FIG.
[0027]
In step S10 shown in FIG. 10, if the ID number is OK, it is determined whether or not the front room flag for the anti-passback check of the passerby is set (step S11), and the front room flag is set. If it is, the rotary door 1 is unlocked for 1/4 turn in the direction in which the lock is released, and the OK lamp of the indicator lamp CRb is primarily lit (steps S12 to S13). If the front room flag is not set, the NG lamp of the indicator lamp CRb is primarily turned on (step S14).
[0028]
When the revolving door 1 is rotated within a predetermined time, the passer's flag of the passer who has read the card reader CR2 is not raised (indicating that he has gone out of the front chamber Cb) (steps S15 to S16). In addition, when it determines with NO in step S10, S11, S15, and after passing step S16, it returns to step S1 shown in FIG.
[0029]
Next, the passage of the door 2 will be described. First, the time of entering a room will be described. In FIG. 11, two persons are collated by card readers CR3 and CR4, and both passers-by ID cards are read within a predetermined time (step S17). If both ID numbers are OK, the indicator light CRb The OK lamp is primarily turned on (step S19), and it is determined whether or not the IN buttons CRc of the card readers CR3 and CR4 are pressed within a predetermined time (steps S20 and S21).
[0030]
When it is determined in step S20 that the IN button CRc of the card reader CR3 has been pressed within a predetermined time, or when it is determined in step S21 that the IN button CRc of the card reader CR4 has not been pressed within the predetermined time. Next, it is determined whether or not the fingerprint collation by the fingerprint reader B1 is OK within a predetermined time and the main room flag is not set (step S22). If the main room flag is not set, the OK lamp of the indicator lamp CRb is set. Is primarily turned on (step S23), and the electric lock of the door 2 is primarily unlocked (step S24), and the process proceeds to step S31 shown in FIG. That is, although two people are collated, it is possible to enter a room by ID discrimination of only one person.
[0031]
On the other hand, if it is determined in step S20 that the IN button CRc of the card reader CR3 is not pressed within a predetermined time, or it is determined in step S21 that the IN button CRc of the card reader CR4 is pressed within a predetermined time. In this case, the retina collation by the retina reader B2 is OK within a predetermined time, and it is determined whether or not the main room flag is set (step S25). If the main room flag is not set, the indicator lamp CRb is turned on. While the OK lamp is primarily turned on (step S26), the electric lock of the door 2 is primarily unlocked (step S27), and the process proceeds to step S33 shown in FIG. Similarly, although two people are collated, it is possible to enter a room by ID discrimination of only one person.
[0032]
If NO is determined in step S18, the NG lamp of the indicator lamp CRb is primarily lit and the process returns to step S17 (step S28). If NO is determined in step S22, the NG lamp of the indicator lamp CRb is primarily turned on and the process returns to step S17 (step S29). Similarly, when it is determined NO in step S25, the NG lamp of the indicator lamp CRb is primarily lit and the process returns to step S17 (step S30). In addition, if the use of the fingerprint reader B1 and the retina reader B2 is determined by a passerby in advance, the lighting method of the NG lamp of the indicator lamp CRb may be changed (for example, blinking) or notified by an alarm or the like when used incorrectly. And intruders can be detected.
[0033]
Next, when the door 2 is opened in step S31 shown in FIG. 12, the passer's main room flag is set (step S32). Similarly, when the door 2 is opened in step S33, the main room flag of the passer-by is set (step S34). And when both main room flags stand, each electromagnetic lock of rack RA and RB can be removed (steps S35-S36). On the other hand, if neither main room flag is set, only the electromagnetic lock of the rack RA can be removed (step S37). The rack automatically locks when closed by hand. In other words, the number of electromagnetic lock release controls differs depending on whether two people enter or only one person enters.
[0034]
Next, the time of leaving from the main room Rm will be described. In FIG. 13, the card reader CR5 is read (step S38), and it is determined whether or not the lead passer's main room flag is set (step S39). If the main room flag is set, the indicator light CRb is OK. The lamp is primarily turned on and the electric lock of the door 2 is temporarily unlocked (steps S40 to S41). And when the door 2 opens, the main room flag of the lead passer is not raised (steps S42 to S43). If it is determined NO in step S39, the NG lamp of the indicator lamp CRb is primarily lit and the process returns to step S38 (step S44). That is, when leaving the room, the exit control is performed based on the anti-passback check of each person.
[0035]
As described above, according to the above-described embodiment, two people are collated, but an anti-passback check by only one person can be performed by intentionally displaying that only one person enters the room by inputting a button. In addition, the security level is improved by using different biometric IDs. For example, if Mr. A is determined to be a fingerprint and Mr. B is determined to be an iris, the person entering the room can be regarded as an intruder when attempting to perform an iris verification using Mr. A's card. In addition, only one ordinary rack is touched when one person enters the room, and a high-security rack can be touched when two persons enter the room, thus reducing the overall labor force (allowing one person to enter the room). And can improve the security level.
[0036]
The present invention can be implemented according to the following embodiments.
(1) Not only two-person verification but also verification of a plurality of three or more persons can be similarly performed.
(2) As an ID determination means, a numeric keypad or biometric ID may be employed in addition to the card reader.
(3) The IN button may be eliminated, and it may be set not to enter the room at the time of initial personal ID data registration.
(4) The fingerprint reader B1 and the retina reader B2 that are collated when entering the main room may be eliminated.
(5) The fingerprint reader B1 and the retina reader B2 can be made in the same manner using any other biometric ID such as iris, signature, and voice.
(6) When one person enters the room, the fingerprint reader B1 and the retina reader B2 may be used for verification.
(7) Anti-passback check may not be performed.
(8) The rack may be opened separately by ID discrimination, mechanical key, or manually.
(9) An alarm may be issued when the fingerprint reader B1 and the retina reader B2 are operated incorrectly (when Mr. A operates the retina reader B2 despite being the fingerprint reader B1).
[0037]
【The invention's effect】
As described above, according to the present invention, in an entrance / exit management system in which a plurality of persons are identified and both can be accessed when the ID determination result is OK, it is possible to enter and exit only a small number of passers-by. You can get a management system.
