Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure in which only a specific person can unlock an automatic lock by operating a communication means such as a mobile phone at the entrance of a room in a building and enter the room. Auto-lock unlocking system.

[0002]

2. Description of the Related Art In places where it is not necessary to strongly prohibit outsiders from entering, such as entrances to apartments, unlocking is performed using a password. That is, the occupant of the building can enter the PIN on a visitor's call machine installed outside the entrance, unlock the door, and enter the building without having the entrance key. On the other hand, when entering each section (room) in the building, since it is necessary to completely prevent outsiders from entering for protection of privacy and crime prevention, the unlocking method using a password etc.
Not adopted. In particular, the unlocking of an auto-locking door with an enhanced security function is based on the use of a key. Therefore, when a specific number of persons such as sales representatives share a room having an auto-locking door, each person holds a key such as a card key and enters the room using the key.

[0003]

As described above, the unlocking of the self-locking type door is exclusively performed by using a key. However, the use of keys also has the following disadvantages. First, even when the number of users in a room is large, keys must be prepared for all users. For example, when a large number of contract employees use a room as a sales office, when hiring new contract employees or ending contracts, it is necessary to rent or return keys, which makes the work of managing keys complicated. Become.

In the case of unlocking with a key, it is not possible to grasp the entry status such as the name of the person who entered the room and the time of entry. Therefore, even if an outsider borrows a key and enters the room illegally, it is not possible to identify the person who lent the key to the outsider and to know the time of unauthorized entry I can't do that either. Further, if the key is lost or stolen, an outsider who has obtained the key can easily misuse the key. To prevent this abuse, all keys used must be replaced with new ones,
If a metal key is used, an unexpected expense will be required to make a new key. In addition, since it takes time to change to a new key, there is a possibility that an outsider can abuse during that time.

The present invention has been made in view of the above-mentioned problems of the prior art, and allows only a specific person to enter a room by an easy operation without using a key. It is an object of the present invention to provide an automatic lock unlocking system that can prevent outsiders from entering a room with safety.
