JPH0489981A - Door unlocking method - Google Patents

Abstract

PURPOSE:To prevent a registered code number for ill purpose by allowing a door to be unlocked first when the input number entered from a door control means is identical to the code number, which has been set remotely via a telephone circuit. CONSTITUTION:In a monitoring center 1, a code number is stored in a code number memory means 4 of a door locking device 3 through a telephone circuit 2. In conformity to an instruction from the center 1, an emergency operator 5 enters the instructed code number in a code number input device 6. The number entered in this input device 6 is compared by a code number judging means 7 with the code number stored in the memory means 4, and when they are identical, an unlock signal is given to the door 8. For a third party person 11 who has eventually acquired the code number from the emergency operator, the monitoring center 1 changes the code number to prevent the code number from being used for ill purpose.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for unlocking a door of a building to be remotely monitored.
In particular, the present invention relates to a door unlocking method suitable for emergency personnel to unlock the door of a building to be monitored based on instructions from a remote monitoring center.

[Conventional technology]

In order to prevent crimes by outsiders who know the PIN number, conventional devices set a condition that the elevator failure detection signal is "present" in addition to matching the PIN number, so that even if the PIN number is known, It was configured so that it could not be unlocked when the elevator failure detection signal was "absent".

[Problem to be solved by the invention]

In the above-mentioned prior art, even if the password is leaked to a third party, the third party who knows the password cannot unlock the entrance door when the failure signal of the elevator is "no". However, if there is a wide-area, long-term power outage or if the power is intentionally cut off, the elevator will issue a failure signal due to the power outage, and a third party who knows the password will be able to unlock the entrance.

The present invention makes it possible to easily and frequently change the registered PIN to prevent the PIN from being leaked and being unlocked by a third party who knows the PIN or by a staff member who is no longer in charge. The purpose is to provide a method for unlocking the door.

[Means to solve the problem]

In order to achieve the above purpose, in a door unlocking method that consists of a device that allows the door of a building to be unlocked by a PIN code, a PIN code set from a remote location via a telephone line and a PIN code input from the door operating means are used. The feature is that the door is unlocked when the input numbers match.

[Effect]

The door of the object to be monitored is unlocked only when the password transmitted and set from the monitoring center to the monitoring device matches the number input by the monitoring personnel dispatched at the direction of the monitoring center. This prevents anyone other than the emergency personnel from unlocking the lock, and prevents misunderstandings about the lock for security reasons.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG.

In the figure, a monitoring center 1 stores a password in a password storage means 4 of a door locking device 13 via a telephone line 2. On the other hand, the monitoring center 1 instructs the emergency personnel 5 about the password. The emergency personnel 5 is dispatched to the scene and inputs the password instructed by the monitoring center into the password input device 6. The PIN determination means 7 compares the PIN stored in the PIN storage 4 with the value input into the PIN input device 6, and outputs an unlocking signal to B8 if the PIN is correct. do. This allows the emergency personnel 5 to enter the building 9. When the emergency personnel 5 who knows the W# identification number leaves the company and becomes a former emergency personnel 10, the monitoring center can change the password, so the former emergency personnel 10 cannot misuse the password. Additionally, for a third party 11 who has obtained the password of the emergency personnel 5 by some means, the monitoring center 1 can change the password after the emergency personnel 5 leaves the building 9.
Misuse of the password by a third party 11 can be prevented.

Although the above-mentioned embodiment does not mention the passwords of persons other than the emergency personnel 5 in the building 9, a plurality of password storage means 4 are provided, and the password storage means 4 are under the control of the monitoring center.
If the configuration is configured so that the PIN code can be set from the monitoring center for the building, Yoshikawa's BIJF identification number for items other than emergency equipment can be used according to the convenience of the building, and the PIN code for emergency personnel can be changed only in an emergency. It can be managed separately from the PIN numbers of people other than personnel.

〔Effect of the invention〕

According to the present invention, since the password can be set from the monitoring set, it is possible to prevent the password from being misused. Also,
Emergency personnel do not need to memorize a different PIN number for each building, and are instructed to enter the PIN number each time from the monitoring center, which has the effect of preventing problems such as forgetting a PIN number or losing a memo. .

Claims (1)

[Claims] (1) When unlocking a building door using a device that allows the door to be unlocked using a PIN, the PIN set from a remote location via a telephone line matches the input number entered from the door operating means. A door unlocking method characterized by unlocking the door at times.
