JP2012180709A - Crime-prevention system door - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a system door with a high crime prevention effect that can prevent data skimming and duplication of an IC card, prevent a suspicious person from intruding, and enable confirmation of an alarm.SOLUTION: An external card reader/writer 1B is installed on the outdoor side of a door Z, and after a card inserted for unlocking goes through a secondary check by an internal card reader/writer 1A installed on the indoor side, the card is stored for internal management with only a password rewritten. Identification of a person in the house is made by the stored card, and detection of intrusion of a suspicious person, management of locking and unlocking of an automatic lock, and crime prevention are conducted in conjunction with a heat-sensitive human sensor 3A on the indoor side of the door and an external heat-sensitive human sensor 2A.

Description

The present invention relates to an ID card electric lock device to which a new password is contributed each time it is used, and a security door system provided with a security sensor that detects and warns a suspicious person from entering a room using a card and a human sensor. .

An electric lock is provided on the door of each room for crime prevention, and the electric lock is unlocked using a card reader or a numeric keypad input device. With the above devices, anyone can enter the room if the card is stolen or the input number is known. In order to solve such a problem, there is a place where an electric lock device using biological information having the highest crime prevention property is provided.

However, when the human body authentication is used for a general household or a hotel room, it is a troublesome work because it requires frequent access and registration of a large number of authentications. There is a need for a locking method that can be easily authenticated and has a high crime prevention effect.

If the storage medium is unlocked by the numeric keypad and the storage medium is used by the human brain, it is rarely known to others, and if the password is changed in a short period of time, the security will be high, but these operations should be performed constantly. Is hard.
This can be solved by rewriting the IC card PIN after unlocking the old pass and new pass.
It is also stored in an indoor IC card reader / writer in a reading state, combined with a heat / human sensor, sensed by a resident and a suspicious person, and outputs a lock / unlock / alarm signal from the controller.

For example, in the case of a key or card key used by an unspecified number of people like a hotel, crime prevention will not improve unless periodic key / lock exchange and card password change, and it is not possible to change the card pass for each individual It ’s hard. The present invention can be used as a new key by a device that automatically changes to a new pass each time a card key or IC card password of the holder tag attached to the key is used, and is stored in an indoor card reader in an authenticated state. Therefore, since the resident is confirmed, it is possible to prevent the intrusion of the suspicious person and to confirm the warning, and it is not necessary to make honey.

1 is a schematic view showing an embodiment of a door locking / unlocking and indoor security system according to the present invention.

The external IC card reader / writer and the indoor IC card reader / writer check the data and change password registration. However, depending on the usage, it can be configured as a detection reader / writer integrated inside and outside the door. Cards inserted from the outside can also be stored for authentication in the room. When a key or remote control key is used, the IC card function is attached to the key ring tag, an IC tag is attached, the alarm is cleared by an indoor reader when entering the room, and a new unlock password is recorded at the same time.

FIG. 1 is a diagram showing an embodiment of a door locking / unlocking and internal security system. There is a card reader / writer 1B for unlocking the door outside the door Z, and the inserted card is read by the card reader 1B. Then, the controller 1C detects and confirms the unlocking, and then the indoor card reader / writer 1A contributes the new password and records the old password together.

By keeping the indoor card reader / writer 1A in the detected state, it is in the home authentication state and the outdoor alarm 2B does not operate. For example, when the resident is absent, the suspicious person does not use the card, In case of intrusion by such a method, if the card key is not detected and stored in the indoor card reader within a certain time, it is sent from the control device 1C to the alarm device 2B and an alarm is generated. In addition, it is possible to create an absence state with a remote controller or the like at the time of going to bed and to arrange an external human sensor 2A to enhance crime prevention.

Further, in the home confirmation state, the indoor door lock is automatically locked, and the door lock is released when approached by the detection by the thermal human sensor 3A. Also, if the lever is opened and closed without taking the indoor card, a warning can be given, and it is prevented from being removed because it is near the unlocking part.

In the case of remote control keys and metal keys other than card keys, the key holder's tag part is made up of an IC card, hooked on the interior 1A, the alarm is released, and the password is automatically contributed.

In addition to being effective in preventing data skimming and duplication in the case of an unspecified number of keys at a hotel, etc., an internal authentication device can be desired to have a crime prevention effect.

This is a locking / unlocking system that improves the security of doors. A non-contact IC card reader / writer is provided outside and inside the door compartment, and a new password is contributed for each external unlocking, and the old password is recorded. It is a locking system that can also be used for indoor crime prevention management and locking management by storing it in the door in a non-contact IC card reader / writer. Indoor security lock system that sends signals such as indoor non-contact IC card reader / writer and heat sensor for heat detection to the control device to perform locking / unlocking management and suspicious person alarm etc.
