Fire alarm equipment that performs two-way transmission of fire, control, etc. signals and multiple intercoms installed in each residential unit, collective entrance, management room, etc. are interconnected via telephone lines, and intercom call control signals are transmitted. This system is equipped with a communication equipment that superimposes a transmission signal from the fire alarm equipment from the side repeater and transmits it to the receiving side repeater to make a call.

(Function) According to the configuration of the present invention, when a calling operation is performed using the intercom, a call control signal is given to the repeater installed on the calling side, and the calling side receives the call from the receiver. A call control signal is superimposed on the transmission signal from the repeater and sent to the receiver, and when the receiver receives and decodes the call control signal, it transmits the call control signal for the call at the timing when the called repeater is called. In addition to sending out,
The receiving side repeater decodes the call control signal sent via the receiver, instructs the intercom to make a call, and also establishes a line connection to form a communication line with the calling side. be.

In bidirectional transmission using the transmission line 40, addresses are set in advance for each of the repeaters 2, 22, and 32, and the transmission control unit 12 sequentially calls the repeaters according to the predetermined address order. Polling is performed, and the format of the transmission data sent from the transmission control unit 12 to the repeater has a predetermined number of address bits followed by a predetermined number of control bits, and the desired control data is sent at the same time as the repeater is called. It is designed to be superimposed and sent out.

On the other hand, the repeaters 2, 22, and 32 check the address bits of the call data sequentially sent from the transmission control unit 12 of the receiver 10, and when they receive address data that matches their own set address, It decodes the contents of the data bits received following the address bits, and performs control processing, display processing, etc. based on the contents of the data bits. Furthermore, if a fire detection signal, other alarm signal, or even control signal is input to the repeater when the self-call is determined, an abnormality detection signal is input to the transmission control unit 12 together with the self-address. response data with additional control signals added.
For this reason, the fire detector 3 installed in the dwelling unit is connected to the repeater 2 installed on the housing information panel 1a, and the repeater 2 is called when a fire detection signal is obtained from the fire detector 3. Then, the repeater 2 returns to the receiver 10 response data in which fire detection data is added following the self-address. Further, the housing information panel 1a is provided with an indoor receiver 4, and a door lock sensor 5 and a gas leak sensor 6 are connected to the indoor receiver 4, and when theft or gas leak is detected, the indoor receiver 4 is connected to the indoor receiver 4.

The call control signal obtained by the call operation of the call operation section 8 is given to the repeater 2, and is sent out from the repeater 2 superimposed on the transmission signal of the fire alarm equipment. Further, the call control switch 9 is turned on and off by the repeater 2, and when a call control signal is given to the repeater 2 from the call operation section 8, the call control switch 9 is turned on and off by the repeater 2.
The call control switch 9 is closed in response to the input of the call control signal from the call operation unit 8 to the
When the repeater 2 receives a call control signal from another terminal by superimposing it on the transmission signal of the fire alarm equipment,
The call control switch 9 is closed based on the determination of the call control signal by decoding the received data in the repeater 2.

The configuration of the communication device in the housing information panel 1a is the same for the other housing information panels 1b, 1c, . . . .

On the other hand, the control room base unit 20 is also provided with a call operation unit 24 using a numeric keypad or the like and an intercom device 25, and the output of the intercom device 25 is connected to an external call line 50 via a call control switch 26 and a call transformer 28. The call control switch 26 is closed by a call control signal from the call control unit 24 when making a call, and when a call is received, the fire alarm equipment is closed by a call control signal received by the repeater 22 superimposed on the transmitted signal. Closed based on decoding the call control signal from the terminal.

Further, the collective entrance unit 30 is also provided with a call operation unit 34 using a numeric keypad or the like and an intercom device 35, and the output of the intercom device 35 is connected to an external call line 50 via a call control switch 36 and a call transformer 38. When making a call, the call control switch 36 is closed under the control of the repeater 32 using a call control signal from the call operation section 34, and when receiving a call, the call control switch 36 is closed under the control of the repeater 32, which is superimposed on the transmission signal of the fire alarm equipment. Closed based on decoding of received call control signals from other terminals.

Next, the operation of the above embodiment will be explained.

First, in the normal monitoring state, the transmission control unit 12 of the receiver 10 sends a calling signal specifying repeater addresses in sequence to the transmission line 40 to
For example, if a fire breaks out in a dwelling unit in which the housing information panel 1a is installed and the fire sensor 3 outputs a fire detection signal to the repeater 2, the repeater 2 will call the self-calling unit sequentially. When it is determined, response data consisting of a combination of the self-address and fire detection data is sent to the transmission line 40, and the response data from the repeater 2 is received and decoded by the transmission control unit 12, and a fire alarm is sent to the fire reception unit 14. Since the receiver 10 is installed in the management room, the person in charge of the management room can know that a fire has occurred in the housing unit where the housing information panel 1a is installed. .

On the other hand, when a visitor comes to the residence where the housing information board 1a is installed and uses the collective entrance machine 30 to make a call to the housing unit where the housing information board 1a is installed, for example, if a visitor comes to the housing unit where the housing information board 1a is installed, first set up the housing information board 1a on the collective entrance machine 30. When you perform a calling operation such as entering a room number using the calling operation section 34 consisting of a numeric keypad or the like, the calling operation section 34
A call control signal specifying the intercom device 7 of the housing information board 1a is outputted to the repeater 32, the call control switch 36 is closed, and the intercom device 35 is connected to the external call line 50. When the repeater 32 determines a call from the transmission control unit 12 of the receiver 10, it sends response data to the transmission line 40, which includes its own address followed by call data based on the call control signal from the call operation unit 34. That is, receiver 1
In response to the repeater call by 0, the repeater sends response data having a frame structure consisting of (self address) + (calling address) + (calling data). The response data from the repeater 32 is received and decoded by the transmission control unit 12 of the receiver 10, and since the received and decoded response data includes the address data and call control data of the receiving side repeater, transmission The control unit 12 sends to the transmission line 40 the calling data, which is the calling address followed by the calling party's address and calling control data, at the timing of calling the repeater 2 of the called party's address. Therefore, repeater 2, which is the receiving side,
In this case, the call is determined from the received data decoded based on the determination of the own address, and the call is placed on the intercom device 7, and the call control switch 9 is closed. 35 and an intercom device 7 on the receiving side are connected via a telephone line 50, and the intercom device 7 that receives the call picks up the handset, thereby making it possible to communicate with the collective entrance device 30.

Of course, when the call ends, the intercom device 7,
35 gives a call end signal to repeaters 2 and 32, and each of repeaters 2 and 32 opens call control switch 9 to cut off the call line.

Such call control, in which a call control signal is transmitted from a calling side repeater to a called side repeater superimposed on the transmission signal of the fire alarm equipment to make a call, is used to communicate with other dwelling units and the control room main unit 20. The same applies to the time between.

(Effects of the Invention) As explained above, according to the present invention, a plurality of repeaters provided in each residential unit, collective entrance, management room, etc. are connected to a receiver via a transmission line, and the receiver and each repeater are connected to each other via a transmission line. Fire alarm equipment that performs two-way transmission of transmission signals such as fire control signals to and from the equipment, and multiple intercom equipment installed in each residential unit, collective entrance, management room, etc. are interconnected via telephone lines, and the intercom equipment Since the call control signal is transmitted from the calling repeater to the receiving repeater in addition to the transmission signal of the fire alarm equipment to make a call, the call control signal from the calling equipment is transmitted to the fire alarm equipment. Because the transmission is bidirectional from the calling side to the called side, there is no need for the telephone equipment to have a call control function as a private branch exchange, and each intercom device can be connected to each other via a telephone line controlled by a repeater. Since it is only necessary to make a connection, the configuration of the telephone equipment can be simplified and equipment costs can be significantly reduced.

In addition, by simply performing periodic inspections of the fire alarm equipment, since telephone calls are controlled through the fire alarm equipment, the maintenance and inspection of the telephone equipment is also performed at the same time, making it possible to maintain and manage a highly reliable system.
