Abstract

PURPOSE:To eliminate the conventional problem that the structure of an applied building is limited by providing a main device with a conversion table for converting the number of a specified dwelling unit into address data specified optionally for the dwelling unit. CONSTITUTION:A conversion table memory 20 consisting of a ROM is stored with address data for calling dwelling unit devices 4-1, 4-2...4-N, and desired address data is read out of this memory 20 with a ten-key 13. Namely, when a dwelling unit number 101 (room No.1 on 1st floor), for example, is specified in decimal notation on the ten-key keyboard 13, a CPU18 converts this dwelling unit number into a memory address 8001H in hexadecimal notation to specify an addrss in said conversion table 20 and then address data 00010001 consisting of 8 bits as to the dwelling unit number 101 is read out of this memory on the basis of the address.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of the Invention] The present invention relates to an intercom device for housing complexes used in housing complexes such as condominiums, dormitories, and apartments.

[Background of the Invention] Recently, in apartment complexes such as condominiums, the main unit located at the common entrance, the main unit, and the unit units located in each unit are connected via a common communication line and transmission line. An intercom device is used that connects the

In this intercom device, the called residence is called in the following manner by operating a numeric keypad provided on the communal entrance device. In other words, for example, if the called dwelling unit's dwelling unit number is 20
3 (Room 3 on the 2nd floor), when this number is specified using the numeric keypad, address data 0010001 consisting of the upper 4 bits indicating the floor and the lower 4 bits indicating returning to the room will be sent.
1 is sent from the common entrance machine to the transmission line, and the dwelling unit of the called dwelling unit is thereby called.

By the way, the conventional intercom device described above has a one-to-one correspondence between the housing unit number and the address data, so for example, when the address data is composed of 8 bits as described above, if the number of floors of the building is 1 to 15 or less, Additionally, there was the disadvantage that the number of rooms on each floor was limited to 1 to 15 or less, that is, the structure of the building was limited.

Also, even if the address data consists of 8 bits, 5
However, it also had the disadvantage that only 1.15×15=225 address data could be obtained.゛The present invention is
In view of these conventional problems, it is an object of the present invention to provide an intercom device for apartment complexes that can be applied to buildings of various structures and that can obtain more address data than ever before.

[Configuration of the Invention] In order to achieve the above object, the present invention includes a plurality of dwelling units,
In an intercom device for apartment complexes, which is connected to a main device that selects one of these dwelling units to make a call via a common communication line and transmission line, the number of the specified dwelling unit is transmitted to the unit. The main device is provided with a conversion table for converting the address data into arbitrarily set address data, and the designated dwelling unit is called by sending the address data to the transmission line.

[Explanation of Examples] Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 conceptually shows an embodiment of an intercom device for apartment complexes according to the present invention. This device connects a communication line 2 and a transmission line 3 to a common entrance unit 1 placed at the common entrance, and connects the communication line 2 and transmission line 3 to the unit units/l-1, 4- placed in each dwelling unit. It has a configuration in which 2° to 4-N are connected in a multi-drop manner.

As shown in FIG. 2, the communal entrance device 1 includes a microphone 11,
A panel section 16 equipped with a speaker 12, a numeric keypad 13 for selecting a called dwelling unit, a key display device 14, a call button 15, etc., and a memory in which a CPU such as a microprocessor, a control program for the CPU, etc. are stored. 19, a control section 21 equipped with a conversion table memory 20 to be described later, an audio circuit 22, and the like.

The first conversion table memory 20 consisting of ROM is stored in each of the above-mentioned dwelling units 4-1, 4-2. . . , 4-N is stored, and desired address data is read from this memory 20 by operating the numeric keypad 13. That is, when, for example, the dwelling unit number 101 (Room 1 on the 1st floor) is specified in decimal by operating the number pad 13, the CPU 18 converts this dwelling unit number into a hexadecimal memory address 8001H as shown in FIG. Specify the address of the conversion table memory 20 using
Address data 00010001 consisting of bits is read from this memory.
゛The address data for each dwelling unit stored in each memory address of the memory 20 is arbitrarily (mechanically) set in advance depending on the building oil, etc.

・This embodiment has 6 conversion table memories 20 as described above.
The housing unit number specified using the numeric keypad 13 is converted into preset address data. This address data is sent from the CPU 18 to the transmission line 3 together with a control signal such as a paging signal.
゛ □Each residential unit 4-1.4
='i, . The address data is checked against its own address. Therefore, for example, if the address data is for the dwelling unit/machine 4-1, the transmission terminal section of this dwelling unit 4-1 determines that the above address data matches its own address and sends it to the communal entrance machine. Enables calls etc. with 1.

According to this embodiment, the residential unit number, which was conventionally used as address data, is converted into arbitrary address data by the conversion table memory, making it possible to obtain more address data than in the past. That is, 01l
Since room I□0 does not exist, in conventional intercom devices that directly use the house number as address data, if the address data is composed of 8 bits, 15x-
Although only address data for 15=225 dwelling units were obtained, in this example, the upper 4 bits of address support data O'000 and the lower 4 bits of address data 0 were obtained.
000, it is possible to obtain address data for a total of 16×16=256 dwelling units.

□ Also, for example, in the case of a building with 10 floors and 20 dwelling units on each floor, or a building with 20 floors. In the case of a building with 10 dwelling units on each floor, address data for each dwelling unit cannot be obtained because the maximum number of floors and the number of rooms that can be specified using the numeric keypad are 15 in the conventional intercom device, and in the above embodiment, By creating a conversion table that matches the structure of the building, address data for each dwelling unit can be obtained using normal numeric keypad operations.

For example, in the case of a building with 17 floors and 10 residential units on each floor, address data for the residential units up to the 15th floor can be obtained directly from the residential unit number specified with the numeric keypad as in the past, and 16
Of course, it is also possible to obtain only the address data for each dwelling unit on the 17th floor from the conversion table memory.

[Effects of the Invention] According to the present invention, since the residential unit number, which was conventionally used directly as address data, is converted into address data arbitrarily set in advance using a conversion table, the structure of the building to which it can be applied is limited. It is possible to solve the conventional problem of

Another advantage is that more address data can be obtained than in the past.
