Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for managing opening / closing of a key storage chamber by collating human feature points such as fingerprints and a management method therefor.
[0002]
[Prior art]
In a building having a plurality of tenants, a key box as shown in, for example, Japanese Patent Application Laid-Open No. 61-183582 may be installed in order to collectively manage the keys of each tenant near the entrance. The key box is provided with a plurality of key storage rooms for storing the keys of each tenant. Each key storage chamber is provided with a lid that is electromagnetically locked, and is managed so as to determine that the user is a user of the corresponding key storage chamber and release the lock to open the lid.
[0003]
As an apparatus for discriminating individuals, it has been proposed to use an apparatus for collating fingerprints as disclosed in, for example, Japanese Patent Laid-Open No. 61-255539. This is to capture a fingerprint of a predetermined finger, convert the density of the screen into an electrical signal, output the feature point data of the fingerprint, match this with the pre-registered feature point data, and the two match Or inconsistency. When the lid is closed, the electromagnetic lock is released when the matching of the feature point data is determined, and the electromagnetic lock is not released when the mismatch is determined.
[0004]
Here, the input feature point data is sequentially collated with respect to the registered feature point data to find a match between the two. However, since the amount of data for one fingerprint is large, the collation time is long. Therefore, about one second is required for one fingerprint. For this reason, it takes a long time to search for a fingerprint that matches the input fingerprint from a large number of registration data.
[0005]
Therefore, feature point data is stored in correspondence with an identification number (hereinafter referred to as an ID number), and an ID number is input using a numeric keypad or a card to specify the address of the stored data. In this way, the registered data can be searched quickly, and only the searched data needs to be collated, so the processing can be completed quickly.
[0006]
[Problems to be solved by the invention]
In the conventional key management apparatus as described above, since the ID number is input by a numeric keypad or card in addition to the fingerprint verification, it is necessary to operate the numeric keypad or card at any time, which takes time and effort. There is a problem that the verification time becomes longer by the amount of the operation.
[0007]
The present invention has been made to solve the above problems, and an object of the present invention is to provide a key management device and a management method thereof that can easily perform a collation operation under a predetermined condition.
[0008]

Embodiment 1 FIG.
1 to 4 are diagrams showing an embodiment of the first, third, fifth and sixth inventions of the present invention, FIG. 1 is a perspective view of a key box, FIG. 2 is a block diagram of the key box, 3 and 4 are operation flowcharts.
[0012]
1 and 2, 1 is a key box, 2 is a key storage chamber for storing a plurality of keys (six in the figure) and storing keys (not shown), each of which can be opened and closed with a lid. An electromagnetic lock 3 is provided to lock or unlock the lid. 4 is a numeric keypad, 5 is a fingerprint reader for reading a fingerprint, 6 is a display unit for displaying operation modes, verification results, etc., 7 is a CPU, 8 is a ROM, 9 is a RAM, and 10 is an electromagnetic lock for controlling the operation of the electromagnetic lock 3. It is a control unit.
[0013]
Next, the operation of this embodiment will be described with reference to FIGS. Note that the program of this flowchart is stored in the ROM 8.
When operating this apparatus, first, a fingerprint of a predetermined finger is registered, and the lid of the corresponding key storage chamber 2 is unlocked by collating the fingerprint.
A. Fingerprint Registration Operation In order to register a fingerprint, after operating the numeric keypad 4 to set “registration mode”, the finger is placed on the fingerprint reader 5 to register the fingerprint.
In step S1, it is determined whether a registration mode number is input from the numeric keypad 4. If it is input, "registration mode" is displayed on the display unit 6 in step S2, and "password" is input to the display unit 6 in step S3. Please display ".
[0014]
In step S4, it is determined whether a password has been input from the numeric keypad 4 within a predetermined time. If it has been input, "Please place your finger" is displayed on the display unit 6 in step S5. In step S6, it is determined whether the fingerprint reader 5 has read the fingerprint. If not, the process returns to step S5. If the fingerprint is read, the process proceeds to step S7. In step S7, the feature point of the read fingerprint is calculated. In step S8, the numeric keypad 4 is operated to input the number of the corresponding key storage room (hereinafter referred to as the window number).
[0015]
In step S9, "Register OK" is displayed on the display unit 6, and in step S10, the password number, the feature point, and the window number are stored as a set in the RAM 9, and the process returns to step S3. The fingerprint is now registered.
[0016]
B. Fingerprint collation operation In order to collate fingerprints, the “collation mode” is set by operating the numeric keypad 4, and then the finger is collated by placing the finger on the fingerprint reader 5 in accordance with the instruction of the display unit 6.
When the registration mode number is not input from the numeric keypad 4 in step S1 (or when the password is not input within a predetermined time even if the registration mode number is input), whether the verification mode number is input from the numeric keypad 4 in step S11 If it is not input, the process returns to step S1.
[0017]
When the collation mode number is input, “collation mode” is displayed on the display unit 6 in step S12, and the process proceeds to step S13. In step S13, it is determined whether or not the number of registered persons in the key storage chamber 2 is x or more. If x or more, the process waits for a password to be input in step S14. When the operator operates the numeric keypad 4 to input a personal identification number, it is determined in step S15 whether the personal identification number is “correct”. If it is not “normal”, “NG” is displayed on the display unit 6 in step S16. The process returns to step S14.
[0018]
If the personal identification number is “correct”, the process proceeds to step S 17, and “Place your finger” is displayed on the display unit 6. In step S18, it is determined whether the fingerprint reader 5 has read the fingerprint. If not, the process returns to step S17. If the fingerprint is read, the process proceeds to step S19. In step S19, the feature point of the read fingerprint is calculated. In step S20, it is determined whether or not the feature point of the read fingerprint matches the feature point registered in the RAM 9. If not, “NG” is displayed on the display unit 6 in step S21, and the process returns to step S14.
[0019]
If the feature points match, “OK” is displayed on the display unit 6 in step S22 and the process proceeds to step S23. The electromagnetic lock control unit 10 removes the electromagnetic lock 3 of the corresponding key storage chamber 2 stored in the RAM 9. . Thus, the lid of the corresponding key storage chamber 2 is unlocked and opened. Here, the user takes out the key in the key storage chamber 2 or stores the key in the key storage chamber 2. When the lid is closed by hand in step S24, the lid is electromagnetically locked and locked, and the process ends.
[0020]
Next, when it is determined in step S13 that the number of registered persons is less than x, the process proceeds to step S25, and “Please put your finger” is displayed on the display unit 6. In step S26, it is determined whether the fingerprint reader 5 has read the fingerprint. If not, the process returns to step S13. If the fingerprint is read, the process proceeds to step S27. In step S27, the feature point of the read fingerprint is calculated. In step S <b> 28, it is determined whether there is a feature point of the read fingerprint that matches the feature point registered in the RAM 9. If there is no match, “NG” is displayed on the display unit 6 in step S29, and the process returns to step S13.
[0021]
If there is a match between the feature points, “OK” is displayed on the display unit 6 in step S30, and the process proceeds to step S31. The electromagnetic lock control unit 10 releases the electromagnetic lock 3 of the corresponding key storage chamber 2. Thus, the lid of the corresponding key storage chamber 2 is unlocked and opened. Here, the user takes out the key in the key storage chamber 2 or stores the key in the key storage chamber 2. When the lid is closed by hand in step S32, the lid is electromagnetically locked and locked, and the process ends. Here, S13 constitutes a medium selecting means, S13 to S20 constitute a first discriminating means, and S13, S25 to S28 constitute a second discriminating means.
[0022]
In this way, the ID number input from the numeric keypad 4 as an identification medium and the fingerprint that is a human body feature point are used, and which of the ID number and the fingerprint is used depending on the number of people registered for the key storage room 2. I am trying to select it. In other words, when the number of registered people is x or more, individuals are identified by collating ID numbers and fingerprints, and when the number of registered people is less than a predetermined value, individuals are identified only by collating fingerprints. become.
[0023]
In addition, fingerprint verification is sequentially performed on registered data as described above, but the verification time is shortened when the number of registered users is small. At this time, since the ID number is not verified, the operation time is shortened.
[0024]
Embodiment 2. FIG.
FIG. 5 shows an embodiment of the second invention of the present invention and is a main part operation flowchart of FIG. 1 to 3 are also used in the second embodiment.
That is, in step S13, it is determined whether the number of registered persons is x or more. If it is x or more, it is determined in step S41 whether the number of users of the key storage room 2 yesterday is x. If there are more than x persons, the process proceeds to step S14 and waits for the input of a password. If the registered number is less than x or the number of users is less than x, the process proceeds to step S25 to instruct fingerprint verification. Steps other than step S41 are the same as those in FIG.
[0025]
As described above, the first embodiment selects the identification medium according to the number of registered persons in the key storage room 2, whereas the second embodiment has a large number of registered persons but a small number of actually used persons. Since only fingerprints are collated, the same effects as in the first embodiment can be obtained, and management according to the actual condition of the key storage chamber 2 can be performed.
[0026]
Embodiment 3 FIG.
An embodiment of the fourth invention of the present invention is shown. In the third embodiment, the personal identification is also performed by the personal identification number. In the third embodiment, the personal identification number is extracted from the feature point data of the fingerprint. It is what you use. That is, the feature point data is stored in the RAM 9 corresponding to the password (or ID number), and the password is used as an address number for extracting the feature point data from the RAM 9. Specifically, this can be realized by removing steps S15 and S16 in FIG.
[0027]
In this embodiment, the personal identification number is input from the numeric keypad 4. However, the feature point data from the RAM 9 can be obtained from an identification medium other than human feature points such as a card (magnetic, IC, optical, non-contact, etc.). You may make it input the PIN code (or ID number) for extraction.
In this way, the same effects as those of the first embodiment can be obtained, and the processing time can be further simplified to shorten the response time.
[0028]
Other embodiments.
Instead of a fingerprint, a discrimination means that uses a human body such as a voiceprint, retina, signature, handprint, face shape, or a function associated therewith, that is, a biometric discrimination means is used.
An indicator lamp (light emitting diode or the like) is provided in the vicinity of the numeric keypad 4 and the fingerprint reader 5, and one or both of the numeric keypad 4 and the fingerprint reader 5 are displayed by lighting thereof to clearly indicate the operating device to the operator.
(3) Instead of controlling the opening and closing of the lid of the key storage room 2, this key box 1 is used for setting whether to start or end the intrusion monitoring of the corresponding room. This is also used in combination with the lid opening / closing control of the key storage chamber 2.
[0029]
(4) When the key box 1 starts to be used, only the fingerprint is verified. When the number of people increases, the input from the numeric keypad 4 is also used.
[0030]
