Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an unlocking device for a building entrance when an emergency worker enters a building.

[Prior art] Conventionally, in the event of an elevator failure, emergency personnel must enter the building, so keep the entrance and exit keys at a maintenance company or ask them to provide a secret code for electric locks,
The key to the building entrance was being operated.

[Problems to be solved by the invention]

In a general house where a home elevator is installed, in the event that the elevator fails, the terminal device attached to the elevator takes in the failure signal of the elevator and automatically notifies the monitoring center of the maintenance company via the telephone line. . On the basis of this report, emergency personnel proceed to the fault recovery. At this time,
If there is no one except the person trapped inside the elevator in the building, the rescue work will not be possible even if it arrives at least if the key to the building entrance is not unlocked. Further, it is difficult for an elevator maintenance company to keep keys of a contracted building because the target is a general house. Also, in case of trouble such as loss of key,
This poses a security risk directly to residents.

An object of the present invention is to provide a building entrance / exit unlocking device capable of unlocking a building entrance / exit even when an emergency person does not have a key of the building when an elevator fails.

[Means for solving the problem]

An object of the present invention is to provide an elevator, a terminal device for notifying the operation failure state of the elevator, and an input / output device for a building entrance / exit unlocking device provided with a locking device which can be remotely operated at an entrance / exit. When the input signal of the elevator coincides with the identification code transmitted from the center device monitoring the state of the elevator to the terminal device, the terminal device of the elevator transmits an unlocking signal to the locking device in conjunction with the failure signal of the elevator. This is achieved by unlocking the doorway of the building by outputting.

[Action]

When the elevator failure signal is input, the elevator terminal device reports the failure information to the monitoring center of the maintenance company via a telephone line according to a preset procedure. The monitoring center selects personnel for recovery and transmits a signal input by the emergency personnel upon arrival to the terminal device.
The signal input from the input device at the entrance of the building is taken into the terminal device and collated with the signal transmitted from the monitoring center. If the two signals match, the terminal device checks for the presence or absence of a failure signal of the elevator, and if so, sends an unlock signal to the controller of the electric lock.

For this reason, if the signal from the input device matches the identification code transmitted from the monitoring center and the elevator is out of order, the key at the entrance of the building is unlocked. That is, even if the emergency personnel do not have the key of the building, the doorway of the building can be unlocked.

〔Example〕

 Hereinafter, an embodiment of the present invention will be described with reference to FIG.

FIG. 1 is an overall configuration diagram showing one embodiment of a building entrance / exit unlocking device of the present invention.

1 is an electric lock at the entrance of the building. Reference numeral 2 denotes a controller that controls locking and unlocking of the electric lock 1. Numeral 3 designates a password provided near the electric lock 1 for inputting a password. Reference numeral 4 denotes a key for directly operating the electric lock 1 manually. 5 is an elevator control panel. Reference numeral 6 denotes a terminal device which takes in the above-mentioned signals, such as the failure signal from the control panel 5, the operation status, and the call signal of the intercom 8 in the elevator car 7, and reports them via a telephone line. Reference numeral 9 denotes a monitoring center for monitoring the status of the elevator, which receives a notification from the terminal device 6, processes the information, and transmits information to the terminal device 6. 10 is a service station that arranges emergency personnel.

At normal times, the electric lock 2 at the entrance of the building is locked and unlocked using the key 4.

The elevator fails and the elevator control panel 5 outputs a failure signal to the terminal device 6 in a specific sequence.
The terminal device 6 reports information to the monitoring center 9 via a telephone line. Alternatively, when a person trapped in the elevator car 7 operates the intercom 8, the terminal device 6
Connects the intercom 8 to the monitoring center via a telephone line after a predetermined time. Thus, in an emergency, the monitoring center 9 grasps the situation and requests the service station 10 to dispatch personnel.

Further, the monitoring center 9 transmits the idNO of the dispatched personnel to the terminal device 6. In the terminal device 6, the idNO of the personnel
Is stored in the memory area. The numeric keypad 3 is connected to the terminal device 6, and an emergency staff member arrives and inputs idNO. The terminal device 6 compares the input of the numeric key 3 with the idNO of the personnel transmitted from the monitoring center 9, and if they match, determines whether or not there is an elevator failure signal. The terminal device 6 outputs an unlock signal to the controller 2 when there is an elevator failure signal and the input of the numeric key 3 matches the transmission from the monitoring center 9. Thereby, the electric lock 1 at the entrance of the building is unlocked.

If the elevator is not out of order, the electric lock 1 can be operated even if the idNO from the monitoring center 9 and the input of the numeric key 3 match.
Do not unlock.

Further, it is difficult to abuse for inputting from the numeric keypad 3 and setting the idNO of the person to be determined from the monitoring center 9 each time.

According to this embodiment, when an elevator fails, only personnel designated by the maintenance company can unlock the doorway of the building without a key.

〔The invention's effect〕

According to the present invention, the maintenance company does not need to keep the key of the building entrance in order to enter the building in an emergency. Even if the unlocking method is leaked to a third party, the doorway of the building cannot be unlocked unless the elevator is out of order. Further, even if the idNOs of the emergency personnel are leaked, since the idNO is set on the monitoring center side, it is impossible for a third party to witness and misuse the operation of the input device.
