Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an intercom system for an apartment complex.

[Background technology]

Conventionally, this type of intercom system for apartment complexes is as shown in Fig. 1, in which 1 is an entrance intercom device installed in the entrance lobby of each building A, B, C, etc. of an apartment complex; Each building A, B, C...
This is an intercom device for a dwelling unit installed in each dwelling unit, and the intercom device 1 for the entrance selectively calls each dwelling unit, and an intercom call line is established between the intercom device 1 for the entrance and the intercom device 2 for a specific dwelling unit. A central calling means 1a is provided to connect the terminals and make calls freely. By the way, in such a conventional example, control room intercom devices 3A, 3B, 3C, etc., which are capable of communicating with the entrance intercom devices 1 of each building A, B, C, etc. or the intercom device 2 of each residential unit, are used. are each building A, B,
It was set up in response to C... Therefore, these management room intercom devices 3A, 3B, 3C...
In addition to requiring a large amount of space,
There is a problem that the appearance is spoiled, and since each control room intercom device 3A, 3B, 3C, . . . requires an intercom communication device, the configuration becomes complicated and the cost increases.

[Purpose of the invention]

The present invention has been made in view of the above points, and its purpose is to provide an intercom system for apartment complexes in which the intercom device for a control room is miniaturized, the configuration is simple, and the cost is low. be.

[Disclosure of the invention]

(Embodiment) Figures 2 to 4 show an embodiment of the present invention, in which an intercom system for apartment complexes similar to the conventional example is used as an intercom device 3 for each building A, B, and C. A call indicator lamp L _A corresponding to the buildings A, B, and C receives a call signal from the central calling means 1a of the entrance intercom device 1 disposed in the entrance lobby and the calling means of the intercom device 2 for each dwelling unit. A call display means 4 that lights up L _B and L _C , and an intercom device 1 for the entrance of buildings A, B, and C selected by the building selection switches S _1A , S _1B , and S _1C
Alternatively, a line switching means 5 for setting an intercom call line between the residential intercom device 2 and the intercom device 2;
An intercom device 8 is installed in the management room. In the figure, 6 _A , 6 _B , 6 _C are connected to the communication lines 11 _A , 11 _B , 11 _C at their contacts r _A , r _B , r _C
7 is a latch circuit that latches the selection data by the building selection switches S _1A , S _1B , S _1C consisting of push button switches, and 9 is an up-down detection circuit that detects whether the handset of the intercom communication device 8 is up or down. The latch circuit 7 is reset when the handset goes up or down. S _2A , S _2B , and S _2C are call switching contacts controlled by the output of the latch circuit 7. _10A , _10B , _10C are control signal lines that transmit calling signals, _13A , _13B , 13C are intercom devices 1 for the entrances of each building A, B, and _C from the control room.
Alternatively, it is a call selection switch for calling each dwelling unit intercom device 2 and making a call, and is a numeric keypad for inputting the address (residential unit number) set corresponding to the entrance intercom device 1 or each dwelling unit intercom device 2. and a call switch Sb that is turned on during a call. Note that a calling signal for mutually calling each intercom device 1, 2, and 3 to perform an intercom call is transmitted as a time division multiplexed signal through control signal lines _10A ,
10 _B and 10 _C. The call display means 4 and the line switching means 5 are controlled by a control circuit 15 using a microcomputer.
_A , 15 _B , and 15 _C are realized.

(Operation of the Embodiment) Now, if a specific dwelling unit is called using the central calling means 1a of the entrance intercom device 1 of building A of the apartment complex, the specific dwelling unit intercom device 2 of building A and the entrance intercom will be called. It becomes possible to make an intercom call with the device 1. In addition, if you call the control room from the entrance intercom device 1 of building A or any of the intercom devices 2 for residences, the call display light L _A corresponding to building A on the control room intercom device 3 will light up and the call will be sent from building A. It is displayed that it is a call, and contact _rA of switching relay _6A is turned on. If the manager presses the building selection switch _S1A corresponding to building A, the selection data is held in the latch circuit 7 and the call switching contact is
_S2A is turned on, the call line _11A is connected to the intercom call device 8, and an intercom call is made between the control room intercom device 3 and the entrance intercom device 1 of Building A or any of the residential unit intercom devices 2. It will be possible. In addition, when calling the entrance intercom device 1 of each building A, B, and C or the intercom device 2 for each dwelling unit from the management room side, for example, press the building selection switch S _1A to select building A, and press , just press the call switch Sb after inputting a predetermined address using the numeric keypad Sa of the call selection switch _13A .

The present invention is configured as described above, and receives a call signal from the central calling means of the entrance intercom device of each building and the calling means of the intercom device for each dwelling unit, and lights up the call indicator lamp corresponding to the building. An intercom device for a control room is provided, which is equipped with a call display means for displaying a call, and a line switching means for setting an intercom call line between the intercom device for the entrance of the building selected by the building selection switch or the intercom device for the dwelling unit. The intercom system for the control room corresponding to each building is integrated and miniaturized, which has the advantage of not requiring a large installation space and not detracting from the aesthetics.
Since there is no need to provide an intercom communication device for each building, the structure is simplified and costs can be reduced.
