The invention according to claim 3 is the security-enhanced automatic locking device characterized in that at least one input terminal for inputting the biometric information of the individual is installed on each floor of the multilayer floor. is there.

According to a fourth aspect of the present invention, there is provided a security-enhanced automatic locking device in which a personal ID code or other personal information is stored in the card key for each user. In this case, each card key becomes a card unique to each individual, and each person needs to use it properly even if it is a resident in the same room.

According to a fifth aspect of the present invention, there is provided a security-enhanced automatic locking device characterized in that the personal ID code and other personal information of all persons permitted to enter the room are stored together with the card key. According to such a configuration, all registered housemates can share the card, which is practically convenient.

In the invention of claim 6, when it becomes necessary to invalidate the card key due to loss or cancellation of the contract, the biometric information and personal ID code registered in the biometric information registration table 20 and other personal The security-enhanced automatic locking device is characterized in that the old card key can be disabled by deleting or rewriting information. With such a configuration, when a resident is changed due to moving or the like, it is possible to cope with the change by simply changing the stored contents of the biometric information registration table without replacing the electric lock body each time.

In the security-enhanced automatic locking device according to the present invention, in order to confirm an occupant or other individual who has proper entry qualifications for each room against an automatic locking device (auto-lock door system) applicable to various apartment houses. In addition, each biometric information registration table for registering in advance the biometric information unique to each individual and the personal ID code in association with the room number is provided. The card key (or IC key) used by each individual who has the entry qualification stores a room number, a personal ID code and other necessary personal identification information. In this case, when there are a plurality of persons permitted to enter the room, it is possible to appropriately select whether to store a single personal ID code for each individual or whether to include personal ID codes of all persons who can enter the room such as family members.

When a card key is inserted into the electric lock card entrance of the room number by a person who wants to enter the room, refer to each biometric information registration table corresponding to the room number and register it in the registered personal ID code and card key The personal ID code is verified. A signal for unlocking the electric lock is generated only when the identity of these data is confirmed and it is determined that the person is authorized to enter the room. Therefore, each time a card key is inserted, an unlock signal is sent only when the person is a regular admitted person with respect to the room number. In addition, registration, maintenance, and management of each individual biometric information registration table are managed in a strict management system by an administrator, a management association, a management company, or the like. The security-enhanced automatic locking device according to the present invention also contributes to prevention of illegal intrusion due to picking or the like.

In the security-enhanced automatic locking device according to the present invention, if the user has been locked out of the room without having a card key, the device is already connected to an input terminal for inputting personal biometric information at any time. Enter the same biometric information as the registered biometric information. When a match between newly input biometric information and registered data in the biometric information registration table is confirmed, an unlocking signal is generated only within a preset delay time, and the user can enter the room. As a result of adopting this configuration, even if the card key is lost, it is possible to prevent illegal entry by the lost old card by rewriting part of the old data registered in the biometrics information registration table. .

In addition, even when the occupant cancels the contract, the old card key cannot be used by invalidating the corresponding data registered in the biometrics information registration table, which is expensive and complicated in operation. Unauthorized entry can be prevented without replacing the attached electric lock body. The new information may be registered as a personal ID code, a room number, and individual biometric information corresponding to a new card key issued to a new resident. Since registration, maintenance, and management of each biometric information registration table are managed in a strict management system as described above, economic operation is possible while strengthening security.

Hereinafter, preferred embodiments of the present invention will be disclosed with reference to the accompanying drawings. FIG. 1 is a system configuration block diagram showing an embodiment of an enhanced security automatic locking apparatus according to the present invention. The electric lock main body 10 includes a locking mechanism 12 having a hook that can be inserted and removed toward the receiving hole on the hook side, and an IC card key or other type of card key insertion / reading unit 14 in the same manner as a general lock. .

The locking mechanism 12 includes a mechanism that is automatically locked without performing a special closing operation when the door is closed, and prevents entry from the outside, and is unlocked only when an electrical signal for unlocking is applied. It is configured to be. In addition, in order to respond to an emergency situation that has become uncontrollable due to a system failure due to a power failure due to natural disasters, etc., a mechanical unlocking key can be used under appropriate management, and emergency release can be made possible. desirable. The card key insertion / reading unit 14 reads a personal ID code from the inserted card key, and generates an output signal such as a room number in which the electric lock body 10 is installed, a personal ID code, and the like.

The biometrics information registration table 20 includes a fingerprint, iris pattern, in addition to a personal ID code by a resident for each room number via a registration terminal device 30 installed in a management room, a management office, a management association, etc. Each piece of biometric information selected from a palm print, a blood vessel pattern of the palm, etc. is registered according to the room numbers 1, 2,..., N. It should be noted that registration, deletion, re-registration, and the like of each information with respect to the registration terminal device 30 must be strictly managed by an administrator or a management office.

In addition, when there are a plurality of people living together such as a family, it is convenient to store in a storage area belonging to the same room number. In addition, the authentication terminal 40 based on each individual biometric information is configured such that the same kind of biometric information as information registered in advance in each individual biometric information registration table 20 can be read at any time, and the conditions are met. In addition, the authentication signal is output only for a preset time.

In the vicinity of the center of the system configuration block diagram shown in FIG. 1, an unlocking condition determination logic circuit 50 surrounded by an alternate long and short dash line is shown. An unlocking signal is generated for the locking mechanism. When a card key is inserted into the electric lock body 10 installed in each room, the first input terminal of the first AND element 52 is the room number where the electric lock is installed, and the individual read from the card Data extracted from the ID code and other biometric information is input.

Data including the personal ID code read from each biometric information registration table 20 is input to the second input terminal of the first AND element 52 using the room number transmitted from the electric lock as a key. In this way, if the identity is recognized between the personal ID code and other data input to the first terminal and the data read from the registration table 20 input to the second terminal, an ON output is generated and OR is generated. An unlocking output is applied to the locking mechanism 12 of the electric lock body 10 via the element 54, and as a result, the locking mechanism 12 is unlocked and can enter the room.

Naturally, the output data for the counterfeited or altered card key does not match the data read from each biometric information registration table 20, so that no output for unlocking occurs. As countermeasures against counterfeit cards and altered cards, in addition to personal ID codes and data recorded on legitimate cards, data partially extracted from biometrics information, the year of birth in the Western calendar and Japanese calendar It is also possible to add a measure for ensuring the distinction of authenticity data by adding a password or the like using a combination of alphanumeric characters as appropriate. Thus, the determination in the first AND element 52 is used to generate an ON signal for unlocking when the card key is owned and the used card key is valid.

In the security-enhanced automatic locking device according to the present invention, in the automatic locking mechanism (auto-locking) door system, a person who wants to enter without a card key due to an accident or loss is registered in a valid registered room. It has a configuration that allows entry into the room on condition that the person is a permitter. In a situation where the conventional auto-lock door system is misunderstanding or momentary, it goes out of the room without possession of the card and it becomes impossible to enter the room, so it goes out to the manager or the management room and gives a spare card key. There were inconveniences that had to be borrowed or unlocked by an administrator. In particular, there is a greater possibility of encountering such a situation, such as when there are younger or older families. The same applies to the case where the user goes out of the room without possessing the card key as described above, the case where the card key is forgotten in the office or in the car, or the case where the card key is lost while away from home.

In such a case, it is the same as the biometric information registered in advance for each biometric information authentication terminal 40 installed near the room phosphorus, for example, near the elevator on the same floor or on the wall surface at the end of the corridor. Enter biometric information for each individual according to the method. In this case, when the room number is also input, each piece of biometric information corresponding to the room number is read from each piece of biometric information registration table 20, and the second AND element 56 is connected to the first and second terminals, respectively. Apply and judge identity. Note that the entire registration area of the information registration table 20 may be specified electronically by biometric information input without inputting the room number.

As a result, if the identity of both data is confirmed, the second AND element 56 generates an ON output necessary for unlocking over a preset time and transmits it to the locking mechanism 12 via the OR element 54. , Unlocked while the ON signal continues. Since this type of unlocking allows the entry of a room permitter who does not have a card key without the cooperation of an administrator or an administrator, it is sufficient to allow an appropriate time, for example, several tens of seconds to several minutes. It is desirable to set an optimal time by timer control according to the number of rooms, the length of the hallway, and the like.

In the security-enhanced automatic locking device according to the present invention, in addition to the unlocking control of the electric lock corresponding to the room number, each individual biometric information registered in advance including the personal ID code of the card key holder It is configured to authenticate the validity of the card key in consideration of the information extracted from the card, so that the forged or altered card key can be distinguished and the security can be improved. In addition, various information such as fingerprints, voice prints, irises, palm prints, palm vein patterns, etc. have been developed and put into practical use as personal ecology-specific information. It can be appropriately selected in consideration of the above.

In this way, since the card key is managed by adding the personal information of the authorized person to enter the room in addition to the room number and information specific to the electric lock, the resident has moved away, the card key has been lost or stolen, etc. In the case of use by a group of companies, etc., even if the right to enter the room is lost due to a person leaving the company, etc., it can be handled by deleting or invalidating the corresponding personal registration information on the system side, which is expensive. There is no need to replace the electric lock body.

Furthermore, by installing individual biometrics information input terminals on appropriate locations near doors of residences, around elevators, at the bottom of corridors, on staircase landings, etc., even if you do not have a card key, If the metric information confirms that the person is an authorized entry person, unlocking and entry are possible for a predetermined time. When it is necessary to request the administrator to unlock with the master key, etc., even if it is not available at midnight, early morning, holiday, etc. or it is difficult to request due to care, etc., by entering the biometric information of the person at any time Authentication enables easy unlocking and entry.

According to the security-enhanced automatic locking device according to the present invention, by applying to a condominium, an apartment, a dormitory, a weekly apartment, etc., the card key taking into account biometric information is used, so the security at the time of entry is enhanced, In addition, it is easy to handle situations such as a resident or other authorized person entering the room and the card key is closed. There is an advantage that the replacement cost and the work time can be saved.

It is a block diagram which shows the system configuration | structure of the security reinforcement | strengthening automatic locking device which concerns on this invention.
