Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint entrance locking / unlocking system which reads an attendant recognition mark and automatically sounds in a visited dwelling unit to lock / unlock an electric lock at a common entrance.

[0002]

2. Description of the Related Art Conventionally, a common entrance lock / unlock system for electrically locking / unlocking doors has been used in houses, buildings and the like. This joint entrance lock / unlock system comprises a lobby intercom provided near the common entrance door and an electric lock control system for locking / unlocking the common entrance door.

The lobby intercom is provided with an operation unit such as a ten-key pad and a camera.

In such a joint entrance lock / unlock system, when unlocking in response to a call from a visitor, the master unit installed in the dwelling unit confirms the visitor on the monitor and then unlocks the lock. Then, the unlocking signal is sent to the electric lock at the common entrance via the electric lock control system and unlocked.

Further, when a resident or the like unlocks the common entrance from the outside, by operating the operation unit and inputting a predetermined common password for the resident, the electric lock control system can be operated. Compared with the PIN code registered in
When both match, the electric lock is unlocked.

It is also possible to insert the reverse master key held by a manager or the like into the key portion of the lobby intercom, and turn the key to unlock the electric lock.

In addition, recently, there is also a device which uses an identification card or the like to be unlocked by being sent to an electric lock at a common entrance via the electric lock control system.

[0008]

However, when a visitor, for example, a family member or a relative of a resident who does not know the personal identification number, or a resident who has forgotten the personal identification number, passes through the common entrance. Even if the resident operates the lobby intercom and confirms it one by one, he or she cannot pass through the common entrance.

On the other hand, there is a problem that the resident side cannot unlock the shared entrance unless the resident side confirms this and operates it from the master side one by one, and the unlocking operation at the shared entrance is troublesome. This is even more troublesome for resident homes with many visitors.

On the other hand, if the unlocking operation is performed by the personal identification number or the reverse master key or the identification card is used, the labor of the resident is not necessary. For example, by knowing the personal identification number, the identification card, etc. Since an intruder who has acquired the password can unlock the common entrance without being known to the resident, the resident side has no way of knowing that the unlocking operation has been performed, which is a security problem.

It should be noted that it is not possible to apply the above-mentioned reverse master key to a person who is expected to enter the entrance because it will increase the cost.

The present invention has been made in consideration of the above circumstances, and it is possible to unlock the electric lock at the common entrance without bothering the resident and to recognize that the common entrance has been unlocked. It aims to provide a joint entrance lock and unlock system.

In addition to the operation of ringing, an intercom display is configured to provide an identification display according to the visitors.

In this case, the intercom display section is
Since it is configured to display the identification display according to the visitors, if different identification displays are recorded and registered corresponding to the attendance recognition marks, it is possible to easily identify the prospective visitors etc. just by looking at the display. .

The joint entrance lock / unlock system according to claim 5 of the present invention is the joint door lock / unlock system according to claim 1, wherein the controller is configured to notify the visitor based on the visitor recognition mark read by the camera of the lobby intercom. On the other hand, a timer schedule for setting the time zone to execute the automatic ringing mode that automatically rings the intercom of the visited place specified beforehand and the display ringing mode that prohibits ringing and displays only It has a function.

In this system, since the controller has a timer schedule function for setting the time zones of the automatic call mode and the display call mode, the automatic call mode is set in the daytime and the display call mode is set at the nighttime. Therefore, it is possible to prevent noise caused by ringing at night.

The joint entrance lock / unlock system according to claim 6 of the present invention is the joint door lock / unlock system according to any one of claims 1-5, wherein the intercom is an intercom with a television monitor.

In this system, the lobby intercom is an intercom with a TV monitor, so that a prospective person can talk while watching the TV monitor.
