BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0013]
FIG. 1 is a diagram showing a configuration of a password input type lock device according to an embodiment of the present invention. In FIG. 1, a password input type lock device 1 of this embodiment is used for a keyless entry system of a rental apartment, for example, and includes a lock device 3 attached to a frame 2. The handle 4 is connected to the lock device 3 by a mechanical device (not shown). The lock device 3 is provided with a latch bolt 5 operated by a handle 4 and a dead bolt 7 that is locked and unlocked by a cylinder lock 6 as in the conventional lock device. The frame 2 above the cylinder lock 6 is provided with a plurality of input switches 8 including a keyboard including numeric keys 0 to 9. The security code input type lock device 1 controls unlocking by means of a security code input via the input switch 8, and also controls execution, setting, change, clearing and temporary invalidation of a security code, which will be described later. A control circuit (not shown) that functions as a password control means for controlling and managing the password is provided.
[0014]
FIG. 2 is a diagram showing a configuration of the control circuit. In FIG. 2, the control circuit is configured by an IC such as a one-chip microcomputer, and includes a control unit 21 that performs various control operations according to a program, and a storage unit 22 that stores a set personal identification number.
[0015]
The control unit 21 is connected to the input switch 8, and a password is input to the control unit 21 via the input switch 8. The control unit 21 is connected to a locking / unlocking control unit 23 composed of an actuator such as a solenoid or a motor as a driven device for operating the deadbolt 7 of the locking device 3, and controls the locking / unlocking based on the input password. The drive of the unit 23 is controlled to unlock. Further, a display unit 24 such as a buzzer or a lamp is connected to the control unit 21. The control unit 21 manages and controls the first to fourth passwords having the functions shown in the function matrix of FIG.
[0016]
In FIG. 3, in the password input type lock device of this embodiment, four passwords of a first password, a second password, a third password and a fourth password can be set for each room. . The first personal identification number is assigned as a personal identification number used by the resident of each room of the apartment house. The second personal identification number is assigned as a personal identification number that is used when a candidate who enters a vacant room inspects the room. The third personal identification number is assigned to a construction personal identification number used by a construction and maintenance company. The fourth personal identification number is assigned to a personal identification number used by an administrator who manages the house.
[0017]
As shown in FIG. 3, in addition to the function that can be unlocked by inputting the PIN, the first PIN for the resident is set after the input of the first, second or fourth PIN. Alternatively, after the first or fourth password is input, the first password can be cleared, and after the input of the fourth password, the first password can be temporarily invalidated.
[0018]
In addition to the function that can be unlocked by inputting the second security code, the second security code for viewing can be set or changed after the fourth security code is input, and the fourth security code can be input. Thereafter, the second password can be cleared, and after the fourth password is input, the second password can be temporarily invalidated.
[0019]
When the first password is set, the second password for private viewing is invalidated. Furthermore, when the first password is cleared, the second password for viewing is validated. Such a second PIN is changed from a valid one at any time by a rolling (one-time) technique. Various methods are conceivable as a changing method. For example, the method can be arbitrarily changed based on a date, a used number, or a table in which a password is registered in advance. When a plurality of second passwords are prepared and invalidated, they are invalidated collectively. On the other hand, when a plurality of second passwords are prepared and the revoked numbers are re-validated, all or some of the prepared numbers may be validated.
[0020]
In addition to the function of unlocking by inputting the third password, the third password for construction can be set or changed after the input of the third or fourth password, and the fourth password can be changed. After the input of the number, the third password can be cleared, and after the input of the fourth password, the third password can be temporarily invalidated.
[0021]
If the first password is set, the third password for construction is invalidated. Further, when the first password is cleared, the third password for construction is validated.
[0022]
In addition to the function that can be unlocked by inputting the password, the fourth password for the administrator can be set or changed after the input of the fourth password. The first, third, and fourth passwords are assigned to passwords required when replacing a battery serving as a power supply of the apparatus.
[0023]
One or a plurality of such first to fourth personal identification numbers can be independently set. The set first to fourth passwords are stored in the storage unit 22 under the control of the control unit 21, and among the passwords stored in the storage unit 22, the cleared password is the password of the control unit 21. It is deleted from the storage unit 22 under control. The first to fourth personal identification numbers are collectively managed by a personal computer or the like prepared for the management of personal identification numbers such as the use status.
[0024]
Next, a setting procedure of enabling / disabling the first password for the resident, the second password for viewing and the third password for construction will be described with reference to the flowchart shown in FIG. I do. The procedure of the flowchart shown in FIG. 4 is executed by the control unit 21 based on a program.
[0025]
In FIG. 4, first, as an initial setting, a second password, a third password, and a fourth password are respectively set (SET), and the set passwords are stored in the storage unit 22 (steps S401 to S403). ). After the initial setting is performed, it is determined whether or not the first password for the resident is set (step S404). If the first password is set, the set password is set. Is stored in the storage unit 22 (step S405).
[0026]
On the other hand, if the first password has not been set, it is determined whether the first password has been deleted (step S406). As a result of the determination, if the first password has been deleted, the first password is deleted from the storage unit 22 (step S407). On the other hand, if the first password has not been deleted, it is determined whether or not the password has been input via the input switch 8 (step S408).
[0027]
If the result of the determination is that no password has been entered, it is determined again whether or not the first password in step S406 has been deleted. On the other hand, when the password is input, it is determined whether the first password is set and activated (step S409). As a result of the determination, if the first password is set and validated, it is determined whether the password input in step S408 matches the first password (step S410). As a result of the discrimination, when the inputted password coincides with the first password, the password is unlocked by the inputted password (step S412).
[0028]
On the other hand, if the input password does not match the first password, it is determined whether the input password matches the fourth password for the administrator (step S411). As a result of the determination, when the input personal identification number and the fourth personal identification number match, the input personal identification number is unlocked (step S412). On the other hand, if the input personal identification number does not match the fourth personal identification number, the process returns to step S404 to determine again whether or not the first personal identification number has been set.
[0029]
On the other hand, in the determination processing in step S409, if the first password is not set, it is determined whether the input password matches the second password for private viewing (step S413). If the input password matches the second password as a result of the determination, the password is unlocked by the input password (step S412). On the other hand, if the input password does not match the second password, it is determined whether or not the input password matches the third password for construction (step S414). If the input password matches the third password as a result of the determination, the password is unlocked by the input password (step S412). On the other hand, if the input personal identification number does not match the third personal identification number, the above-described processing of step S411 is performed.
[0030]
In this way, when the first password for the resident is set, the second password for viewing and the third password for construction are invalidated, and the password is entered by inputting the second and third passwords. It can no longer be locked. On the other hand, if the first password is cleared and not set, the second and third passwords are validated and unlocking can be performed by inputting the second or third password.
[0031]
Therefore, in this embodiment, when the first password for the resident is set, the second password for viewing is invalidated, and when the first password is cleared, the second password is changed. It will be re-enabled, preventing unauthorized intrusion and theft by unlocking at a time other than at the time of viewing, using the second password notified to the applicant at the time of viewing, improving the crime prevention effect It is possible to do.
[0032]
Such first to fourth passwords are actually operated as shown in FIG. In FIG. 5, at the time of construction of an apartment house, after attaching the password input type lock device of this embodiment to each room, at the time of construction or maintenance, the construction and maintenance contractor unlocks using the third password, Perform construction and maintenance (shown in (1) of FIG. 5). The occupant wishing to enter a vacant room unlocks using the second password notified from the administrator at the time of the preview and previews the room (shown in FIG. 5 (2)). The resident sets a desired first personal identification number when moving in. At this time, the second and third passwords are invalidated (shown in FIG. 5 (3)).
[0033]
After setting the first password, the resident unlocks with the set first password (shown in FIG. 5 (4)). When the resident leaves, the resident clears the set first password (shown in FIG. 5 (5-1)). Alternatively, the maintenance work may be performed by the maintenance contractor to clear the first password (FIG. 5 (5-2)). In this case, the maintenance company may have the resident give the first password when the resident leaves. Alternatively, the administrator may clear the first password by using the fourth password for the manager (shown in FIG. 5 (5-3)). If maintenance is required during the occupancy and the occupant needs to be unlocked, and the resident is not present, the occupant will be unlocked using the administrator's fourth password in the presence of the administrator (see FIG. Shown).
[0034]
【The invention's effect】
As described above, according to the present invention, when the first password is set, the second password is invalidated, and when the first password is cleared, the second password is activated again. The unauthorized access and theft can be prevented by unlocking at the time other than the time of viewing by using the second security code notified to the applicant at the time of the viewing, so that the security can be improved.
