Abstract

PURPOSE:To prevent the a prank call or an error call from a common entrance machine is an interphone system for a housing complex. CONSTITUTION:Interphone devices 2-1 to 2-n are provided with identification(ID) number storing circuits 11 and a switch 7a for selecting the validity/invalidity of ID number collating, and at the time of a collating mode, an ID number inputted at the time of receiving a call from the common enterance machine 1 is collated with a number stored in the circuit 11 and interphone speaking is enabled only when both numbers coincide with each other.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intercom system for an apartment house used in an apartment house such as a condominium, and more particularly to improvement of an intercom device for each dwelling unit.

[0002]

2. Description of the Related Art FIG. 3 is a system configuration diagram of a conventional intercom system for a housing complex. In the figure, reference numeral 1 is a collective entrance machine which is arranged at a collective entrance of an apartment house and calls a designated dwelling unit together with the input of a dwelling unit number, and makes a call with a resident of the dwelling unit. It is transmitted to the dwelling units 2-1 to 2-n.

If it is determined that each of the dwelling units 2-1 to 2-n receives a dwelling unit number signal and transmits it to the CPU 5, and that the transmitted dwelling unit number is its own number, Energize relay Ry6, handset 7
And contact point 6 that connects the gateway 1 with
-A is closed, the ringing tone generation circuit 9 is activated, and when it is detected that the handset 7 is turned off by a resident, the contact 5a is closed to enable the call to the collective entrance 1. It consists of

Next, the operation of the conventional system having the above configuration will be described with reference to the flowchart of FIG. When the dwelling unit intercom emitted from the apartment house entrance machine 1 is called, for example, the first dwelling unit intercom 2-1 is called, the dwelling unit number signal is received by the transmission circuit 4 via the transmission line 3. C
The PU 5 determines whether the received data matches its own address (S-1), and responds, for example, if the value is 1 (S-1).
-2).

Next, the relay 6 is turned on to make its relay contact 6-a to connect the handset to the call line 8 and drive the ringing tone generating circuit 9 to make a ringing tone, for example, "ping pawn". Occurs (S-3). When the resident turns off the handset 7, the contact 7-a is turned on (S-4), and communication with the collective entrance is possible (S-5).
When the resident turns on the handset 7, the contact 7-a turns off. When the CPU 5 detects this, the relay 6 turns off, the contact 6-a breaks, and the call ends (S-6).

[0006]

Since the conventional system is configured as described above, it is possible to call any dwelling unit by entering the dwelling unit number corresponding to the dwelling unit from the collective entrance machine. Since it is possible to call the resident by inputting the dwelling unit number at, there is a disadvantage that even if the system is convenient for the resident, it may cause inconvenience depending on how it is used.

The present invention has been made in order to solve the above-mentioned problems, and an object thereof is to obtain an intercommunal system for collective housing capable of preventing a prank call.

[0008]

An intercom system for housing units according to the present invention is installed in a collective entrance of an apartment house, and is installed in a collective entrance machine for intercom communication with a calling dwelling unit. The personal identification number storage circuit that stores the personal identification number and the personal identification number stored in the intercom of each dwelling unit is provided with a personal identification number storage circuit that sends the personal identification number set to At the time of coincidence determination, a call control means for responding to a specific call and enabling an intercom call, and a switch for setting valid / ineffective switching of the coincidence determination operation of the personal identification number are provided.

[0009]

The call control means according to the present invention performs the matching judgment operation between the personal identification number transmitted from the collective entrance after the dwelling unit number and the personal identification number stored in the personal identification number storage circuit,
Only when a match is determined, a ringing tone is generated for the inhabitants of the dwelling unit, so that a person who does not know the personal identification number will not be misled by a prank call. Further, during the time period when the coincidence judgment operation of the personal identification number is unnecessary, the dwelling unit can be called only by inputting the ordinary dwelling unit number by invalidating the switch.

[0010]

EXAMPLES Example 1. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a system configuration diagram of an apartment house intercom system in this embodiment. In the figure,
The same reference numerals as those in FIG. 3 indicate the same or corresponding portions. In the figure, reference numeral 10 is a valid / invalid setting switch for setting valid / invalid of the coincidence judgment operation of the personal identification number, and 11 is a personal identification number storage circuit.

Next, the operation of this embodiment according to the above configuration will be described with reference to the flowchart of FIG. Similar to the conventional system, it is assumed that a call is made to the dwelling unit intercom 2-1 from the apartment house entrance machine 1. The CPU 5 checks whether the signal received by the transmission circuit 4 is its own address, eg, 1 (S-1), and then checks the state of the secret code valid / invalid setting switch 10 (S-1a). At this time, if the switch is turned on, that is, if it is set to "valid", the received data (the PIN number input on the side of the collective entrance) that is subsequently received, for example, "1, 2, 3, 4" is stored in advance as the PIN number. It is checked whether or not the password stored in the circuit 11 matches the secret code, for example, "1, 2, 3, 4" (S
-1b), and in this case, responds because they match (S
-2), the following is the same operation as the conventional example ((S-3)
~ (S-6).

[0012] The personal identification number of the medical examination is, for example, "4.
3, 2, 1 ”, and if the data does not match the data in the memory circuit 11 (S-1b), no response is made and the operation ends. When the state of the personal identification number valid / invalid setting circuit 10 is set to OFF, that is, "invalid" (S-4), the personal identification number is not checked and a prompt response is made (S-2). The operation is similar to the conventional example ((S-3) to (S-6)).

The collective entrance machine 1 may be provided with a collation lamp and turned on under the following conditions. When the personal identification number setting circuit 10 is turned on after the transmission circuit 4 of the house receives the self-address “1”, that is, when the personal identification number needs to be collated, if the fact is transmitted to the collective entrance 1 via the transmission circuit 4, The collective entrance machine 1 receives this and turns on the verification lamp. As a result, there is an effect that it becomes an effective guidance for the person who operates the call at the gathering entrance.

In the first embodiment, the identification number may be collated a predetermined number of times, for example, up to three times.

[0015]

As described above, according to the present invention, an intercom call can be made with the resident of the dwelling unit at random only when the personal identification number issued to the dwelling unit from the entrance door to the dwelling unit matches the PIN number of the calling dwelling unit. It is possible to prevent use of the intercom for mischievous purposes such as calling a resident. Further, since the resident can be called without inputting the personal identification number by switching the switch of the intercom device, the system is easy for the user to use.
