Description

  The present invention relates to an apartment house intercom system, and in particular, it is possible to easily enter the apartment house even if the PIN code leaks to a third party by periodically changing the PIN code of the automatic door. The present invention relates to an apartment intercom system for preventing.

A conventional apartment house intercom system has an automatic door with an electric lock at the entrance, and the electric lock is unlocked unless it is unlocked by a resident (including the unlocking operation in the room master unit). It was difficult for suspicious people or the like to enter the apartment house. (For example, patent document 1).
JP 2000-101731 A

  However, in the conventional apartment house intercom system, when unlocking the automatic door of the collective entrance, it was done by entering the PIN number at the collective entrance machine, but when a third party was behind the collective entrance machine, The security code may be leaked and the security may be reduced.

  The present invention has been made to solve the above-mentioned problems, and periodically improves the security by changing the personal identification number and notifying each room base unit or management room base unit of the personal identification number information. Let Another object of the present invention is to provide a collective housing intercom system that can improve security by assigning a PIN to each area even in a large-scale system equipped with a plurality of collective entrances. Yes.

In order to solve the above-mentioned problem, the invention according to claim 1 is characterized in that a visitor calls a resident to make a call, and a resident who has confirmed the call from the collective entrance machine responds. It consists of a master unit for making calls with visitors, a control unit for controlling the main entrance and the master unit, and an automatic door for visitors or residents to enter and exit the apartment. A control unit that changes a password for unlocking the automatic door at a predetermined cycle; a password memory for storing the password changed by the control circuit; A communication circuit for notifying the changed password to the living room master unit and the management room master unit is provided.

Further, the invention of claim 2 is that, in claim 1, a plurality of collective entrance machines are connected, and the controller controls call control for restricting the parent unit that can be called from each collective entrance machine. Based on the information in the memory, a password for unlocking the automatic door that is changed at a predetermined cycle for each gateway, and the changed password based on the information in the call restriction memory. This is characterized in that it is transmitted to the parent room that is subject to call control of the machine.

Further, in the invention of claim 3 according to claim 1 or claim 2, the code number memory continuously stores the code number before the change for a predetermined period, and the predetermined period is both before and after the change. It is characterized in that the password of the password is made valid.

According to the invention of claim 1, since the personal identification number is periodically changed, it is possible to maintain security even if it is known to a non-resident. It is possible to prevent intrusion.

According to the invention of claim 2, in the case of a large-scale apartment house to which a plurality of entrance halls are connected and separated for each entrance hall, a password is assigned to each. Even if it is a resident of an apartment house, it can prevent entering into another area, and can improve security further.

According to the invention of claim 3, since the password before change is valid only for a predetermined period, it is possible to enter the housing complex even if the user forgets to confirm.

BEST MODE FOR CARRYING OUT THE INVENTION The best embodiment to which the apartment house intercom system of the present invention is applied will be described below with reference to the drawings.
FIG. 1 is an external view showing a configuration of an apartment house intercom system according to an embodiment of the present invention. FIG. 1 is a diagram showing a configuration of an apartment house intercom system according to an embodiment of the present invention. Installed in the room, installed at the entrance of the management room base unit 1, collective housing for communication with the collective entrance units 2a, 2b... And the room base units 3a, 3b. .., The management room master unit 1 or the collective entrance units 2a, 2b... .., connected to the control unit 4 and the collective entrance units 2a, 2b,... For controlling the management room master unit 1, the collective entrance units 2a, 2b,. Automatic door 5a, 5 with electric lock b,... are composed of mobile phones 6a, 6b,.

  Further, the control device 4 includes a communication room 40, 41 for communicating with the mobile phone via the management room base unit 1, the living room base units 3a, 3b... And the collective entrance units 2a, 2b. 42, 43, a control circuit 44 for controlling each circuit of the control device 4, a personal identification number memory 45 for storing a personal identification number, a call restriction memory 46 for regulating each call destination, the collective entrance machines 2a, 2b,. A password candidate registration memory 47 is provided for preparing and using a plurality of password numbers to be changed in advance.

Hereinafter, the operation of the multi-family apartment house intercom system configured as described above will be described.
Here, when a visitor calls a desired resident using the collective entrance machines 2a, 2b... And responds with the living room master units 3a, 3b..., The collective entrance machines 2a, 2b are transmitted via the control device 4. ... and the room base units 3a, 3b, ..., a call between them, and an operation to unlock the automatic doors 5a, 5b, ... by operating the room base units 3a, 3b, ... Since is the same as in the prior art, description thereof is omitted.
In this embodiment, since the management room master unit 1 is connected, the management room base unit 1 is connected to the entrance doors 2a, 2b,. Since it is the same as that of the past also about having a telephone call between, it abbreviate | omits description.
