By operating the switch 16b, a predetermined message command signal is transmitted from the central communication device 1e, and the message lamp 2 of the called intercom unit 2e is transmitted.
There has been proposed one in which 4a is turned on. According to such a configuration, it is convenient for a resident who has returned home from the outside to easily know that there has been a call from the manager by checking the lighting state of the message lamp 24a. Further, the manager does not need to repeatedly call the intercom to the resident who is not present, which is also convenient.

[0003]

However, in the above-mentioned conventional apparatus, in order to turn on the message lamp 24a of the intercom unit 2e installed in each dwelling unit, each time the intercom unit 2e is called,
It is necessary to operate the message switch 16b of the central communication device 1e one by one. Therefore, for example, when the operation of the message switch 16b is inadvertently forgotten, the message lamp 24a of the called intercom unit 2e can no longer be turned on. As a result, in the related art, it may not be possible to reliably transmit the message to the resident who has been absent, which has caused a problem in this point.

[0004] The present invention has been proposed in view of the above points, and even if a specific operation such as operating a message switch of a central communication device is not performed, an intercom is not available due to the absence of a resident. It is an object of the present invention to ensure that a message indicating that there is a message can be transmitted to an intercom unit for which a call cannot be made.

[0005]

According to the first aspect of the present invention, there is provided a communication system for a multi-family housing, which is provided in a management room of a multi-family housing. And a plurality of intercom units installed in each dwelling unit of the apartment house, and sends a message command signal to the central communication device for operating a message notification unit provided in each intercom unit. A call system for multiple dwelling units provided with a possible signal transmission means, wherein the central communication device transmits the call to the intercom unit when the intercom call to the intercom unit is finished or at a later time. Control means for controlling the transmission of a message command signal from the signal transmission means. Means, when a line connection for intercom calls with interphone unit became callee interphone call is made is configured to cancel the sending of the message command signal to the intercom unit of the call destination.

According to a second aspect of the present invention, there is provided a communication system for an apartment complex according to the first aspect of the present invention, wherein the central communication device is provided with a message cancel switch, and the control means of the central communication device is The transmission of the message command signal is also canceled when the message cancel switch is operated during the period from the start of the call to the desired intercom unit to the end of the call.

[0007] The means for notifying the presence or absence of a message provided in the intercom unit in the multi-unit call system according to the present invention as set forth in claim 1 or 2 is provided by a central call device. A message lamp that starts lighting or blinking when a predetermined message command signal is received, or a display unit that starts a predetermined screen display operation can be applied.

[0008]

According to the first aspect of the present invention, there is provided a multi-family call system according to the present invention, wherein a call for intercom communication is made from a central communication device to an intercom unit of a desired dwelling unit. If the resident of the called party is not connected to the line for the intercom call due to absence, etc., and the interphone call is not established,
At the time when the call is terminated or at a later time, the control means of the central communication device drives the signal transmission means to transmit a predetermined message command signal to the intercom unit. Thereby, the predetermined notification means of the intercom unit can be operated (for example, a message lamp is driven). That is, it is possible to operate the notification means of the intercom unit of the dwelling unit where the intercom call was not established without performing a special switch operation on the central communication device, and to reliably transmit the message to the resident that there is a message. Becomes

On the other hand, if the intercom unit responds to the intercom call from the central intercom, and the intercom call is established, the transmission of the message command signal to the intercom unit is canceled by the control of the control means. Is done. Therefore,
When an intercom call is established, the notification means of the intercom unit with which the intercom call was made does not operate improperly.

According to the second aspect of the present invention, the intercom unit does not respond to the call from the central communication device even if the intercom call cannot be established. If the message cancel switch of the central communication device is operated before the operation is completed, no message command signal is sent to the intercom unit. Therefore, even when the intercom call is not established, for example, when the manager determines that there is no need to notify the resident that there is a message, by operating the message cancel switch flexibly, It is possible to arbitrarily prevent the notification means of the desired intercom unit from operating.

[0011]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an example of a hardware configuration of a call system for an apartment house according to the present invention. This system includes a central communication device 1 installed in a management room or the like of an apartment house or the like, and a plurality of intercom units 2 installed in each dwelling unit (only one is shown in FIG. 1 for convenience). It is composed of

A communication circuit 11 provided with the handsets Ha and Hb of the central communication device 1 and the intercom unit 2;
21 are connected to each other via a communication line La, and the transmission circuits 12 and 22 are connected to each other via a signal line Lb. Mutual transmission of various control signals such as a message command signal described later is performed between the transmission circuits 12 and 22, for example, a multiplex transmission method is adopted as a specific communication method.

The central communication device 1 is configured as, for example, an alarm monitoring device for monitoring the presence or absence of an abnormality in each dwelling unit, and a signal processing unit 10 including a CPU or the like.
(Corresponding to the control means of the present invention), in addition to the communication circuit 11 and the transmission circuit 12 described above, a storage unit 13 including a ROM, a RAM, or the like functioning as a system memory;
The display unit 14, the switch unit 16, and the like are connected.

The display unit 14 includes a message transmission confirmation lamp 14a for displaying whether the central communication device 1 is ready to transmit a message command signal to the intercom unit 2, a liquid crystal display or A display screen section 14b composed of seven segments and the like, and a call lamp 14c that lights up during an intercom call are provided.
In addition to the above, an alarm lamp 14d and the like, which perform lighting driving when a signal notifying an abnormal situation such as a fire occurrence is transmitted from the intercom unit 2 to the transmission circuit 12, are provided.

The switch section 16 includes a numeric keypad 16a for inputting a call number of an intercom call, a message switch 16b operated when a predetermined message command signal is to be transmitted from the transmission circuit 12, and a transmission of a message command signal. And a message cancel switch 16c that is operated when it is desired to positively cancel the message.

The signal processing unit 10 controls the operation of each unit in the central communication device 1 and performs signal processing. The signal processing unit 10 is configured to perform the following control during an intercom call with the intercom unit 2. That is, when the handset Ha is picked up and a desired call number of the intercom unit 2 is input using the numeric keypad, the signal processing unit 10 causes the transmission circuit 12 to transmit a call signal to which the call number is added. At that time, the RA in the storage unit 13
In M, data for transmitting a message command signal to intercom unit 2 to be the destination of the intercom call is stored and registered. That is, the flag in the memory is set to 1. In addition, the signal processing unit 10
The message sending confirmation lamp 14a is controlled so as to be turned on.

Next, in response to the intercom call, the handset Hb of the intercom unit 2 on the called side is picked up and an incoming call is made, and when the speech line La is in a line connection state, the signal processing unit 10 In R
The data for transmitting the message command signal registered in the AM is deleted (the flag is set to 0), and the message transmission confirmation lamp 14 is turned off. The signal processing unit 10 also determines whether or not the communication line La is connected, but this can be determined, for example, by monitoring a change in the voltage of the communication line La. In addition, the signal processing unit 10
Not only when the intercom call is established, but also when the message cancel switch 16c is pressed before the handset Ha of the central communication device 1 is restored, the data indicating that the message command signal is transmitted is transmitted in the same manner as described above. It is configured to erase from the RAM.

As a result, data indicating that a message command signal is transmitted is deleted from the RAM of the central communication device 1 when an intercom call is established and when the message cancel switch 16c is operated (the flag is set to 0).
Otherwise, the data remains registered (with flag 1).

The signal processor 10 refers to the registered data in the RAM when the handset Ha is restored after the intercom call is executed. In such a case, if data indicating that a message command signal is to be transmitted is registered in the RAM (if the flag is 1), the intercom unit 2 on the called side is restored when the handset Ha is restored. Against
A predetermined message command signal is transmitted from the transmission circuit 12. When this signal transmission is completed, the data is erased from the RAM, and the message transmission confirmation lamp 1 is sent.
4a is turned off. However, according to the present invention, the transmission of the message command signal does not necessarily have to be performed at the time when the handset Ha is restored, and for example, the handset Ha is transmitted.
A message command signal may be sent out at a point in time when a predetermined period of time elapses after is restored.

On the other hand, if the data indicating that the message command signal is to be transmitted is not registered (when the flag is 0) at the time when the handset Ha is restored, the signal processing unit 10 performs any special processing. Is not executed, the transmission of the message command signal is canceled, and the execution is not executed.

On the other hand, in the intercom unit 2, similarly to the central communication device 1, a signal processing unit 20 composed of a CPU or the like for controlling the operation of each unit and executing signal processing is sent to the above-described communication circuit 21. Signal transmission circuit 22, a ringing signal detecting circuit 28 for executing a bell ringing when a calling signal is received, a speaker SP, a storage unit 23 functioning as a system memory, and a message lamp 24a.
Display 24 having an alarm lamp 24b, etc., a management call switch 26a operated when calling the central communication device 1, an electric lock unlock switch 26b operated when unlocking the electric lock at the entrance of the apartment, and the like. The switch unit 26 and the like provided are provided. The signal processing unit 20 of the intercom unit 2 includes various security sensors 3 for detecting the occurrence of a fire or gas leak, etc., in the I / O port 2.
7 are connected.

In the intercom unit 2, when the message command signal transmitted from the central communication device 1 is received by the transmission circuit 22, the signal processing unit 20 starts lighting driving (including blinking driving) of the message lamp 24a. It is configured to control as much as possible.

Next, a description will be given of an example of use and operation of the above-structured housing communication system. First, when the manager of an apartment house wants to transmit a message to a resident of a predetermined dwelling unit, the handset Ha of the central communication device 1 may be picked up and the call number of the predetermined dwelling unit may be input. As a result, a call to the intercom unit 2 of a predetermined dwelling unit is started.
Is registered with data for transmitting a message command signal. Next, in response to the above-mentioned call, the handset Hb of the intercom unit 2 on the called side is picked up and a response is made. When the telephone line La is connected and an interphone call is established, the RAM of the central telephone unit 1
The data to send the message command signal is deleted. Therefore, in this case, the message command signal is not unnecessarily sent to the intercom unit 2 after the intercom call is finished, and the message lamp 24a of the intercom unit 2 is not unduly turned on. .

On the other hand, the intercom unit 2 does not respond to the call due to the absence of the resident of the intercom unit 2 on the called side, and the handset of the central intercom unit 1 does not establish an intercom call. When Ha is restored, the data for transmitting the message command signal is still registered in the RAM. Therefore, in this case, when the handset Ha of the central communication device 1 is restored, the signal processing unit 10
, A message command signal is sent to the intercom unit 2, and the message lamp 24a of the intercom unit 2 can be appropriately turned on. When the message lamp 24a is turned on, there is no need for the manager to perform any special operation, so that the problem that the message lamp 24a is not turned on due to the manager forgetting to perform a predetermined switch operation is appropriately avoided. It becomes possible. In addition, the resident who has returned home from outside has confirmed that the message lamp 24a is lit, and returns to call the intercom call to the central communication device 1 so that the contents of the message can be properly confirmed.

Even if the intercom call is not established as described above, it may not be necessary to turn on the message lamp 24a of the intercom unit 2 depending on the content of the message to the resident. In this case, the manager only has to operate the message cancel switch 16c of the central communication device 1, and when this operation is performed, no message command signal is transmitted even if the intercom call is not established, and the intercom is not transmitted. The lighting of the message lamp 24a of the unit 2 can be avoided.

On the other hand, when the message cancel switch 16c is operated due to the caretaker's error or carelessness in spite of the desire to turn on the message lamp 24a of the intercom unit 2, the message switch 16b is immediately turned on. You just need to do it. Thereby, when the handset Ha returns, the message command signal can be appropriately transmitted to the intercom unit 2 on the called side, which is convenient. It should be noted that whether or not data for transmitting a message command signal is registered in the RAM can be determined by looking at the message transmission confirmation lamp 14a, so that the switch operation can be performed accurately.

Steps 100 to 100 in the flowchart of FIG.
Reference numeral 117 denotes a series of operation procedures in the central communication device 1 described above.

In the above-described embodiment, the so-called four-wire type using the communication line La and the signal line Lb individually has been described, but the present invention is not limited to this. For example, as shown in FIG. 3, a so-called two-wire system using a communication line Lc may be used (in FIG. 3, the same parts as those shown in FIG. 1 are denoted by the same reference numerals). In the multi-family communication system shown in FIG. 3, the control signal generation circuit 1 of the central communication device 1A is used.
7, a call signal is generated, and the call signal can be appropriately transmitted from the communication circuit 11 to the intercom unit 2A via the line control unit 15. Then, in response to the call from the central communication device 1A, the intercom unit 2A
Is not picked up and the intercom call is not established, an automatic incoming call is made when the call signal detection circuit 28 of the intercom unit 2A detects the call signal a predetermined number of times. When this automatic incoming call is detected on the side of the central communication device 1A, a message command signal is generated by the control signal generation circuit 17 on the side of the central communication device 1 by DTMF or the like, and the intercom unit is connected via the communication line Lc. It can be transmitted to the 2A side.
Thereby, the message lamp 24a of the intercom unit 2A can be appropriately driven to light.

As described above, the present invention can achieve the object of the present invention even when it is configured as a two-wire type, and a specific communication system between the central communication device 1 and the intercom unit 2 is provided. Is not limited.

In each of the above embodiments, the communication circuit 1
Although the type in which the handsets Ha and Hb are connected to the devices 1 and 21 has been described as an example, the present invention is not limited to this. Both the central communication device and the intercom unit are so-called hands-free types without a handset. Is also good. In this hands-free type, it is usual that a call button is provided instead of the hook switch for detecting the pick-up of the handsets Ha and Hb and the returning operation thereof. Therefore, for example, when the call button is operated on the intercom unit side in response to a call from the central communication device, the call line is brought into the line connection state, and the intercom call is established.

Further, in each of the above-described embodiments, the message lamp 2 is used as a notifying means for notifying the presence or absence of a message.
Although 4a has been described as an example, the present invention is not limited to this. For example, intercom unit 2 (or 2
A) may be provided with a display unit composed of a liquid crystal display or the like, and a message on the display unit may be displayed on a screen using characters, graphics, or the like to notify that a message is to be transmitted.

In addition, according to the present invention, the security sensor 3 is attached to the intercom unit 2 as in the above embodiment.
It is not a requirement that the central communication device 1 be connected as the alarm monitoring device.

[0033]

As will be understood from the above description, according to the multi-dwelling unit communication system according to the first to third aspects of the present invention, a message command signal is transmitted to an intercom unit in which an intercom call has been established. While it is possible to appropriately prevent improper transmission, a predetermined message command signal is transmitted to the intercom unit for which intercom communication has not been established without performing any special switch operation on the central communication device. And the desired resident can be notified that there is a message. As a result, it is possible to surely eliminate the risk that a message indicating that there is a message cannot be transmitted to a predetermined resident due to forgetting a specific operation of the central communication device as in the related art, which is extremely convenient. .

In particular, according to the present invention as set forth in claim 2,
Even if the intercom call is not established, if the message cancel switch of the central communication device is operated at a certain time, the transmission of the message command signal to the intercom unit can be canceled.
For example, if the manager determines that there is no need to notify the resident of the message, the message cancel switch is operated to activate the notification means of the desired intercom unit. Can be arbitrarily avoided, which is more convenient.
