In this case the telephone line wire l ₁ connection information from HBC1, intercom information, transmits telephone extension l ₃ a, the connection information l ₃ b respectively every predetermined time. In addition, the main telephone 3 provided with an emergency button switch,
Child telephone 5 ₁ ..., pict TV Tsukiko telephone 24, further sensor connection unit 13, further parent alarm unit 8, and sequentially calls the child alarm unit 15 is returned to the information of each of the emergency button switch state.

Such parent telephone 3 after an hooked up in the normal state (or the child telephone 5 ₁ ..., 24) of the there is an operation of the operation button for external call, the operation signal is a microcomputer through the key scan ramp circuit 306 the interrupt signal INT via fetched data transmission circuit 302 to 301 is to be delivered in the current mode to the signal transmission line l _2.

The interrupt signal is sent at the time of receiving the S1 pulse of the end signal EN as shown in Fig. 13 (a) when the terminal that issues the interrupt is a fixed length terminal, and when the terminal of a variable length is shown in Fig. 13 ( As shown in b), when the S1 pulse of the start signal SY is received, the timing of interruption such as the above-mentioned outside line calling is performed by the former. Now, the above interrupt signal IN
When T is transmitted and HBC1 is received via the data transmission circuit 105, the CPU 101 stops the polling by this interrupt and performs terminal access for address search based on the flowchart shown in FIG.

That is, changing the mode signal of the transmission signal VS ₁ to poll the interrupt address search to access the terminals. With this access, the terminal that has interrupted the address returns the address. In this case, by allocating the terminal address in advance for each group, the address is called in units of groups (address of a common upper bit) at the time of address search,
By returning address data of lower bits at the time of reply, the address search can be speeded up.

Now, it is determined whether the terminal belonging to this address search belongs to page 0. If the interrupted terminal does not belong to page 0, then the HBC1 switches the mode to the monitoring mode for further checking the interrupt flag and determining whether long format transmission or short format transmission is performed. Interrupt flag in reply data of
IRQ is determined that an interrupt request if 1, if more data have been replies "FF", the transmission signal VS ₂ of long format, using the transmission signal VS ₁ of the short format is otherwise HBC1 then accesses the terminal at that address.

Now, when there is a request for an external line connection from the above-mentioned parent telephone 3 and the above-mentioned interruption occurs, and the interruption is confirmed, the HBC 1 accesses the parent telephone 3 in the interrupt flag clear mode to clear the interruption flag IRQ. The external telephone connection request data is received from the parent telephone 3. Upon receiving the request data, the CPU 101 connects the telephone extension l ₁ a or l ₁ b, and in accordance with the connection, connects the circuit extension circuit 312 to the telephone extension l ₃ a or the telephone extension l ₃ b which is vacant with respect to the parent telephone 3.
HBC1 transmits a transmission signal VS having control data for connecting In this connection, the main telephone 3 turns on the indicator lamp indicating the external line connection through the key scan lamp circuit 306 by the function of the microcomputer 301, and the dial tone causes the network circuit 312, the relay contact r _316, and the coupling transformer 313. The sound is emitted from the speaker 318 through the mixing circuit 314 and the amplifier 316. Then, when the dial operation button of the master telephone 3 is pressed, the same interruption as at the time of the interrupt request described above is performed, and the operation dial data is returned from the master telephone 3 as the reply signal RT.

In the HBC1 which has received the operation dial data, the dialer 111 is operated by the function of the microcomputer 101 to make an outside line call. The anti-collision circuit 109 detects that the telephone set is picked up and the telephone is in a talking state by the external telephone which is selectively connected by the external line calling by reversing the polarity of the line, and the automatic notification interrupt is generated by detecting the external line talking state. The CPU 101 performs a control operation such that the control is not performed even when the outside line communication state is detected.
After entering this call state, HBC1 resumes the normal polling operation.

The outside line call from the parent telephone 3 is made to the child telephone 5 ₁ … or 24
Further, the same can be done with the single telephone 6.

When the one-touch dial unit 20 is used to make an outside line call after the outside line connection, it is sufficient to operate the operation button provided in advance corresponding to the telephone number of the other party,
When this operation is performed, the above-mentioned interrupt request operation is performed between the HBC1 and the one-touch dial unit 20, and the operation button data is calculated by the data transmission circuit 202 of the one-touch dial unit 20 as the reply signal RT when the short format is returned. It is transmitted under the control of the processing circuit 201. In the HBC 1 receiving this reply signal RT, the CPU 101 reads out the data corresponding to the operation button of the one-touch dial unit 20 in the abbreviated dial data stored in the RAM 103 in advance, and the dialer 111 makes a dial call to call the other party's telephone. is there.

Next, in the on-hook state, the master telephone 3 (or the slave telephone 5
₁ …, 24) When making an outgoing call, press the on-hook transmission operation button, and when this operation button is operated,
The microcomputer 301 turns on a relay contact r ₃₁₄ connected in parallel to the hook switch HS ₁ through a relay circuit 319 to make a line connection to enable a dial tone to be emitted from a speaker 318. The control processing operation is performed so that the same operation as in the state where the call origination is detected and the handset is picked up is possible.

When an external call is made on-hook and connected to the telephone of the other party, a normal telephone call can be made by taking the handset when the voice of the other party is heard from the speaker 318. When the operation button is operated again to stop the call from the outside line, the microcomputer 301 determines "OFF" and returns the line state to the initial state, and the HBC1 returns to the normal polling operation.

When the call on the parent telephone 3 by the above-mentioned outside line call ends and the on-hook is detected by the hook switch HS ₂ by the microcomputer 301, the parent telephone 3 replies to the HBC1 side with a return signal RT to the HBC1 by sending a return signal RT. Return to normal operating state.

Next, when an incoming signal of 16 Hz is transmitted through the telephone external line l ₁ a or l ₁ b, the corresponding incoming detection circuit 108 of the HBC ₁ detects this signal, and the CPU 101 of the HBC ₁ receives the transmission signal VS ₁ ,
The external line information is transmitted to each telephone 3,5 ₁ …, (24) and the single telephone adapter 7 in the simultaneous mode, and each telephone 3,5 ₁ …, (2)
4) and signal tone circuits 305, 40
5 and the speakers 318,418,
A sound is emitted from 708, and a display lamp for displaying an outside line flashes through the key scan lamp circuits 306, 406, and 706 to indicate an incoming call.

At this time, when the call rejection button is operated, the operation of the signal tone circuit is stopped by the operation of the microcomputer in the telephone or the single telephone adapter 7 on which the call rejection button is operated, so that the ringing tone is stopped. it can.

Well one of the telephone 3, 5 ₁ ... in a state in which the outside-line display of the display light is flashing (24), when the handset is taken up in 6, the telephone, for example, the interrupt request signal INT from the parent telephone 3 is sent The interrupt processing described above is performed. After this interrupt processing is performed, the request data for the external line connection from the master telephone 3 is sent to the HB by the reply signal RT.
Will be sent to C1.

When this reply signal RT is received, the telephone 3
To connect the network circuit 310 to the telephone extension l ₃ a or l ₃ b corresponding to the incoming telephone extension l ₁ a or l ₁ b by relay contacts r ₃₁₂ , r ₃₁₃ , r ₃₁₅ , Make a call.

When the call state ends and the handset is returned and goes on-hook, an interrupt request is made again by the telephone 3 and the end data is returned to HBC1 as a reply signal RT. Is the relay contact r ₁₁₂
Is released to transmit the line open control data when the telephone 3 is accessed, and the relay contact r ₃₁₃ is opened.

Incidentally, when it is desired to temporarily hold the external line call in the external line call state, the hold button of the telephone, for example, the master telephone 3 may be operated.

That is, when there is a hold operation, the telephone 3 sends an interrupt request signal INT, and after the above-described interrupt processing is performed, the data of the hold request is returned from the telephone 3 as a return signal.
Returned to HBC1 as RT. Amplifier 113 operates the corresponding holding circuit 110 as well as close the telephone line wire l ₁ a or l ₁ b in connection via a resistor and the like have this hold request, a coupling transformer 114, through relay contacts r ₁₁₃ Sends music on hold to the other party. Then, control data for controlling the line opening and the blinking of the indicator lamp for displaying the outside line is transmitted to the telephone 3 to open the line and blink the indicator lamp. Here, if the handset of the telephone 3 is put on-hook, the telephone 3 is put on hold.

Next, to release the hold state, the hold button may be operated again. With this operation, the interrupt request signal INT is transmitted from the telephone 3 to perform the above-described interrupt processing, and the data of the line connection request is returned to the return signal RT. Is sent as Upon receiving this return signal RT, the HBC1 releases the line connection, transmits the line connection control data to the telephone 3, returns to the call state before the hold, and releases the hold state.

Each time a certain period of time elapses in the hold state, HB
C1 activates the signal tone circuit 306 at the time of access to the telephone 3 for which the hold is set, causes the speaker 318 to emit a hold caution sound, and alerts the user that the hold is being performed.
It is also possible to call an extension during this hold.

By the way, in the present system, it is possible to make a call using a so-called short-circuit dial when making an outside line call. Next, the setting operation of this speed dial will be described.

By the way, in the present system, it is possible to make a call using a so-called short-circuit dial when making an outside line call. Next, the setting operation of this speed dial will be described.

First, when an operation button for shortening is operated in any one of the telephones 3, 4 _1, ..., (24) in accordance with the procedure for setting abbreviated dialing, an interrupt request signal INT is transmitted from the telephone, for example, the master telephone 3, and Interrupt processing is performed,
The shortened registration request data from the telephone 3 is sent as a reply signal to HBC1.
Returned as RT. The HBC 1 having received the reply signal RT transmits the shortened registration permission data to the telephone 3. In the telephone 3 receiving the shortened registration permission data, a sound signal indicating the shortened registration permission is output from the signal sound circuit 305 by the operation of the microcomputer 301 and is emitted from the speaker 318. When the user operates a shorter operation button than the telephone 3, the interrupt request signal INT is transmitted from the telephone 3, and the above-described interrupt processing is performed. After this interrupt processing, when the corresponding speed dial button data and the registered telephone number data are returned from the telephone 3 as a reply signal RT, the HBC 1 that has received the data writes the data in a predetermined area of the RAM 103 based on the data. The registration of the speed dial can be continuously repeated until the operation of the operation button indicating the end is completed. When the operation button indicating the end is operated and the data is returned from the telephone 3, the HBC 1 performs this registration. Upon receiving the reply signal RT, control data indicating the end of the shortened registration acceptance is transmitted. Receiving this data, the parent telephone 3 emits a sound indicating the end from the speaker 318 under the control of the microcomputer 301 as in the case of permitting the registration.

Dial registration corresponding to each operation button of the one-touch dial unit 20 can be performed according to the registration of the speed dial.

 Next, a call between extension lines will be described.

If internal calls to call parent telephone 3 child telephone 4 ₁ for example, pick up the handset of the parent telephone 3 First, press the push button dial corresponding to telephone extension. This push operation causes an interrupt signal IN from the parent telephone 3
T is transmitted to the HBC 1, and the extension connection request data is returned from the telephone 3 by the access from the HBC 1 by the above-described interrupt processing. By receiving this reply signal RT, HBC1

Also connected through a predetermined telephone extension l ₃ a or l ₃ b relay circuitry circuit 312 to the contact r _312, r _313, r ₃₁₅ with blinking the indicator lamp extension call to the parent telephone 3 caller The control data is transmitted from the HBC 1 by the transmission signal VS, and the master telephone 3 is connected to the extension.

When the push button dial is released after the extension connection is completed, the interrupt request signal INT is sent again from the master phone 3 to the HBC1, and after the interrupt process, the dial press-down completion data from the master phone 3 is sent to the HBC1. Is transmitted. Based on this data, control data for stopping the sounding of the call notification sound from the HBC ₁ to the called telephone set 41 is transmitted by the transmission signal VS, and the sounding of the call notification sound is stopped.

When the child telephone 4 ₁ handset of the caller is taken at this point, the interrupt request signal INT from the telephone 4 ₁ is transmitted to the HBC1, it transmits the response data as a reply signal RT after the interrupt process. The circuitry circuitry 412 of the telephone set 4 ₁ like the parent telephone 3 the control data extension connection by transmitting the transmission signal VS with respect to the telephone 4 _1, BC has received the response data of a predetermined telephone extension l ₃ a or l ₃
Connect to b.

 With the above connection, extension calls can be made.

In addition, in the case of extension connection, there is a paging mode, and in this case, the push button dial that is set in advance for paging on the calling telephone may be operated instead of the push button dial for individual calling described above. All of the telephones of the above become callee telephones, and all of these telephones notify the above-mentioned ringing tone, and a telephone call can be made with the callee telephone that first picks up the handset. Like this,
Except for the notification control of the ringing tone, the same control processing as the individual ringing is performed.

The respective telephone 3,4 ₁ ... enters the internal call status, 24, or at the single phone adapter 7 is the control data by the transmission signal VS from HBC1 as indicator lamp extension call is lit is transmitted, displayed The internal call status is displayed by turning on the lamp. During this display, even if there is a request for an extension individual connection, the HBC 1 operates so as not to accept the request. However, if there is a simultaneous call request during this display, the HBC 1 operates to stop the call by the current extension connection and give priority to the simultaneous call.

Then doorphone 2 and telephone 3, 4 ₁ ..., it will be described a call between 24.

First, in the case of a call from the door phone 2, a call signal from the door phone 2 is set to H through the door phone interface 106.
Once in BC1, HBC1 operates the speech current supply circuit 117 by channel switch circuit 116 supplies a speech current to telephone extension l ₃ a or l ₃ b through relay contacts r _114, intercom information each phone 3 , 4 ₁ ..., 24, or alone telephone by transmitting the transmit signal VS to the adapter 7, tone circuit is provided to each 305, 405 ... the microcomputer 301, 401 ...
, The chime sound is emitted from the speakers 318, 418,... And the display lamp of the door phone display is blinked to indicate that there is a call from the door phone 2.

When taken up the handset of any telephone This call will connection is performed call state through telephone extension l ₃ a or l ₃ b between the extension call as well as intercom 2 and the telephone, at the same time the The control data for switching the blinking of the display lamp to ON from HBC1 to each telephone
It is transmitted to 3,4 ₁ …, 24, and the respective display lamps are turned on.

Next, when calling the intercom 2 from the telephones 3, 4 ₁ ..., 24 or 6, take up the handset of the telephone and operate the intercom button provided on the telephone or the adapter 7 to operate the HBC1.
Under the control of, a connection with a door phone is made and a call can be made.

A plurality of doorphones 2 are provided, and when there is a call from another doorphone during a call with one doorphone, a connection request for another doorphone can be issued to the HBC1 from the telephone by pressing the doorphone button. . In addition, if the intercom call and the incoming call are simultaneously made, the HBC 1 gives priority to the incoming call and establishes an outside connection to the telephone whose handset has been raised. Further, when the intercom is called during the outside call, the connection request for the intercom 2 and the request for holding the outside line are returned to the HBC 1 by operating the intercom button, so that the communication with the intercom 2 and the holding of the outside line can be performed. This outside line hold release request can be made by re-operating the door phone button. Further, when the intercom is called during the extension call, a connection request with the intercom 2 can be issued by operating the intercom button. In this case, the extension call is stopped. The phone 3,4 ₁ ..., sent back to HBC1 intercom number data by pressing the push-button dial corresponding to the intercom number that is set on the intercom 2 together with the connection request in the intercom call from 24 calls the corresponding intercom 2 be able to. If there is no operation of this dial, the last intercom call 2
Select to connect. By operating the incoming call rejection button, the chime sound can be suppressed.

Next, the microphones 317, 417 for collecting the sound of the room where the telephones 3, 4 ₁ ..., 24 and the unit 9 of this system are provided respectively.
So that a so-called room monitor can be performed.

In other words, the telephone in the room you want to monitor, for example, sub-phone 4 ₁
When with the handset lifted monitor setting button is pressed, an interrupt request signal INT from the child telephone 4 ₁ ...
Is sent to HBC1. Then after processing of this interrupt request is made when the handset is returned, the data of the monitor mode is returned to the return signal RT from the child telephone 4 ₁ to HBC1, that it has received the HBC1 receives this reply signal RT data indicating transmitted by the transmission signal VS to the child telephone 4 _1, set the child telephone 4 ₁ of monitor display of the display lamp blink under the control of the microcomputer 401, the child telephone 4 ₁ to the monitor side Show what was done.

Next, when the monitor setting button is pressed on the telephone on the monitor side, for example, the master telephone 3, data is exchanged with the HBC 1 in the same manner as the above-described setting, and the display lamp of the master telephone 3 is turned on. After this lighting, the mixing circuits 414 and 314 of the respective telephones 4 ₁ and 3 are connected to the relay contacts r ₄₁₂ , r ₄₁₃ , r ₄₁₅ , r ₄₁₆ ,
_{r 312, r 313, r 315} , connected through r ₃₁₆ to telephone extension l ₃ a or l ₃ b. The telephone 4 ₁ amp 417 of the monitor-side is operated under the control of the microcomputer 401, a microphone 417
The speech signals collected by from amplifier 417, mixer 414, coupled through the transformer 413 is sent to the telephone extension l ₃ a or l ₃ parent telephone 3 on the monitor side through b, the coupling transformer 313 in the parent telephone 3, the mixing circuit 314 , Speaker 318 through amplifier 316
You will be able to monitor the replayed by.

When the monitor is to be terminated, the room monitor button of the master telephone 3 on the monitor side may be operated. After receiving the interrupt request signal INT by operating the room monitor button and performing the interrupt processing, the master telephone 3 Upon receiving the monitor termination request data, the HBC ₁ transmits the control data for terminating the monitor connection to the telephones 3 or 41 on the monitored side and the monitor side, and terminates the monitor connection.

Note that outside calls and extension calls have priority over the above-mentioned monitor operation, and when these calls are made, the room monitor is automatically suspended and the monitors are restarted after the call ends.
HBC1 controls the terminal side.

The above operation is a control operation related to a call, but an operation related to security will now be described. First, the sensor connection unit 13 is sequentially accessed by the transmission signal VS in the monitoring mode by normal polling, and the monitoring data of the various sensors 11 connected to each is sent back as the reply signal RT by the access, and the monitoring data is sent. Is transmitted to the parent alarm unit 8 by the control mode transmission signal VS. When an abnormality is detected in the sensor 11, the parent alarm unit 8 operates the voice synthesis circuit 809 and the signal sound circuit 805 under the control of the microcomputer 801, and generates an alarm sound signal and a message signal corresponding to the detected sensor. Sound from the speaker 815, and at the same time the interrupt request signal INT is set to HB.
The alarm data is sent to C1, and after the interruption processing, the transfer data of the abnormal alarm is sent back to the HBC1 from the parent alarm unit 8 with a long acknowledge reply signal RT. The HBC1 which received this reply signal RT has each telephone 3, 4 ₁ ..., 24 having a speaker for reporting.
Control data to the single telephone adapter 7 and the transmission signal VS
In transmission, and the respective mixing circuits 307,407,707 on the basis of the transmission signal VS is connected to the extension telephone l ₃ a or extension telephone l ₃ b, further telephone extension the alarm sound signal and the message signal to the parent alarm unit 8 l Control data to be connected to ₃ a and l ₃ b are transmitted by the transmission signal VS, and an alarm signal and a message signal are transmitted through the telephone extension l ₃ a or l ₃ b to each telephone 3, 4 ₁
, 24 and the single telephone adapter 7, and the respective speakers 318, 418, 718 emit an alarm sound and a message.

When the notification set button is in the set state, the HBC 1 has the microcomputer 801 built-in memory and the RAM 10 of the unit 8 in advance.
The dialer 111 makes a call to the telephone number of the automatic notification destination stored and set in 3. Here, when the notification is started, the display lamp of the notification display is turned on in the parent alarm unit 8.

When the response detection circuit 808 detects that the telephone handset outside the system has been picked up and the line polarity has been inverted, a message signal for notification is output under the control of the microcomputer 801 of the parent alarm unit 8 and a message is output. Is notified, and the display lamp is switched from blinking to lighting. This message is sent simultaneously to each telephone 3,4 ₁ …, 24 and the speakers 318,4 of the single telephone adapter 7.
The message is issued from 18,708, after which this message replaces the alarm sound and the accompanying message.

The number of messages is predetermined, and when the number of messages is reported, the destination is switched to the next automatic report destination. When the report destination does not respond, the report is repeated a predetermined number of times by redialing again.

In addition, the HBC 1 performs a control operation such that the interruption is not stopped even if the detection of the sensor 11 is lost during the automatic notification.

Phone 3,4 ₁ ... in this report, taken up the handset 24, or 6, line as call automatic notification is interrupted under the control of HBC1 the external connection button is pressed mating takes precedence When the connection is established and the call ends, the notification operation after the interruption is restarted.

Now, data for control to ring the emergency bell 27 connected to the sensor connection unit 13 in conjunction with the above-mentioned alarm issuance operation is returned from the parent alarm unit 8 as a return signal RT, and the transmission signal VS of the HBC1 is transmitted. By sensor connection unit
The emergency bell 27 connected to 13 is rung under the control of the arithmetic processing circuit 131.

Further, the parent alarm unit 8 causes the HBC 1 to connect the communication line ₁₆ of the door phone 2 in response to an interrupt request, and an alarm sound and a message are issued from the speaker of the door phone 2 until an automatic notification response is received.

By the way, the above operation has been described with respect to the detection operation of the sensor 11, but the sensor connection unit 13 or the telephones 3, 4 ₁ .
Alternatively, when the emergency button switch provided on the single telephone adapter 7 is operated, an interrupt request signal INT is output. After the interrupt request processing, the emergency button switch operation data is transmitted to the parent alarm unit 8 from the HBC1 by the transmission signal VS. , And thereafter, the alarm issuance and the automatic notification are performed in the same manner as in the detection operation of the sensor 11 described above. When the emergency button switch of the parent alarm unit 8 is operated, the transfer data is returned from the parent alarm unit 8 to the HBC 1 by interruption,
Thereafter, the same processing as in the case of the detection operation of the sensor 11 described above is performed.

Here, the setting of the above automatic notification is performed by the parent alarm unit 8.
The operation of the emergency button switch is more reliable than the malfunction of the sensor 11, so the automatic notification is limited to the operation of the emergency button switch even when the report set button is not set. Switch SW to set
₁ is provided in the parent alarm unit 8, the parent alarm unit 8 sends back along with the data settings automatically reported setting data of the switch SW ₁ when replying to Utsuriho data HBC1, for automatic notification The determination of whether or not is performed by the HBC1. Hence can be performed automatic reporting is always at the time of the alarm due to the operation of the emergency button switch if by turning on the switch SW _1.

By the way, the detection operation of the security sensor 11c in the sensor 11 is effective only when the security alarm is set, and the resetting of the security sensor 11c is performed by using a telephone line system control described later or by using the main alarm unit 8 or A switch provided on the child alarm unit 8a or sensor connection unit that does not have the function of automatically reporting the parent alarm unit 8.
It is able to perform by the operation of the SW _2.

After the interrupt processing an interrupt request is made to the child alarm unit 8a or operating data of the switch SW ₂ of the sensor connection unit 13 during operation, is transmitted to HBC1 is further transmitted by the transmission signal VS from HBC1 to the parent alarm unit 8 registers After receiving the transmission signal VS, the display data is returned to the HBC1 by an interrupt request from the parent alarm unit 8, and the control data from the HBC1 sets and resets the alert of the sensor connection unit 13 and the child alarm unit 8a. Turn on the indicator lamp of. Of course, the operation data is not transmitted to the HBC 1 when the switch SW ₂ of the parent alarm unit 8 is operated.

The alarm issuance at the time of the crime prevention set is a threat to the intruder and is effective when at home, but loses the opportunity to catch the intruder when absent. It is provided with a switch SW ₃ to regulate the broadcast. When this switch SW ₃ is turned on,
Parent alarm unit 8 is in the system sends data to stop the alarm onset report on HBC1 side, thereby restricting the extension connection control of the telephone 3, 4 _1, 24 and speakers 318,418 and 708 single phone adapter 7. Therefore, an intruder can be captured automatically without being noticed by the intruder, and the intruder can be captured.

Since the above automatic notification cannot be performed when the telephone lines l ₁ a and l ₁ b are blocked by a call from outside the system, this system first detects an incoming call on the available telephone line l ₁ a or l ₁ b. The CPU 101 of the HB1 determines whether or not the incoming call is detected by the circuit 108, and if there is a vacant telephone line, the telephone line is used to perform the above automatic notification. If there is no empty telephone line, a message is reported to the telephone line with the highest priority determined in advance, and when this message report ends, the line is forcibly released and the call with the other party is stopped. The above-mentioned automatic call is performed using the telephone outside line. In this way, even if the telephone line that is intentionally connected is called up by a telephone outside the system and the line is occupied, automatic alarming can be reliably performed, and the reliability of the system can be improved. You can.

Telephones 3, 4 ₁ … 24 in a state where the handset is picked up when the sensor 11 or the emergency button switch is operated.
Alternatively or speakers 318,418,708 single phone adapter 7 is connected to the network circuit 312 and 412 side, telephone extension l ₃ a or
l ₃ b, the alarm sound and the message from the parent alarm unit 8 are not notified.
In C1, the signal tone circuits 305, 40 provided for those in a call state
Sending control data to operate 5,705, signal tone circuit 305,4
A warning signal is issued by the sound signal of 05,705 to prevent unreporting.

Next, the operation of the camera switching unit 22 will be described.

First, the camera switching unit 22 turns on the monitor TV camera 21 attached to the door phone 2 in conjunction with the call of the door phone 2 and displays an image on the monitor TV 23. That is, when there is a call signal from the door phone 2, the HBC 1 transmits control data to the camera switching unit 22 by the transmission signal VS,
The corresponding monitor television camera 21 connected to is turned on, and at the same time, control data for starting the operation is also sent to the monitor television 23 by the transmission signal VS to operate the monitor television 23. By this operation, the video signal near the doorphone 2 is converted to a coaxial cable.
the video is projected is sent to the monitor television 23 through l _5.

Here, a plurality of monitor televisions 23 are provided and each telephone 3, 4
HBC1 sends the transmission signal VS so that all monitor televisions 23 are operated first when the interlocking relations are set to ₁ ..., 24, 6 and then the operation of the monitor television 23 which does not correspond to the telephone set with the handset. To display the image only on the monitor TV 23 corresponding to the telephone in communication with the intercom 2 and to stop the operation of the monitor TV camera 21 and the operation of the monitor TV 23 when the call ends. 22 and monitor television 23.

When displaying an image on the monitor TV 23 without interlocking with the door phone 2, it is good to operate the monitor switch provided on the monitor TV 23, and in this case, an interrupt request signal INT is returned to the HBC1 from the monitor TV 23, After the interruption request processing is completed, the HBC 1 transmits control data for operating the corresponding monitor television camera 21 to the camera switching unit 22 by the transmission signal VS, and operates the monitor television camera 21. When the monitor switch is operated again after the end of monitoring, the same processing as in the operation is performed, and the operations of the monitor television 23 and the monitor television camera 21 are stopped.

By the way, in this system, the monitor television camera 21 is sequentially switched by the detection operation of the security sensor 11e. In other words, when the above-mentioned alarm is issued, HBC1
Transmits the control data for sequentially switching the monitor television cameras 21 to the camera switching unit 22 by the transmission signal VS, and sequentially transmits the video signals from the monitor television cameras 21 to the coaxial cable ₁₆ . Transmission signal VS from HBC1 to each monitor TV 23 linked with the operation of each monitor TV camera 21
And display the image on each monitor TV 23,

Next, the equipment load R by the telephone line system control and the multiplex transmission system
The control of will be described.

First, when the selector switch unit 9 or the remote control switch 16 is operated, the interrupt request signal INT becomes H
The HBC1 transmits the control data to the relay control unit 10 so as to control the operated corresponding load R and turns the corresponding load R on or off after the interruption processing is completed.

The control state of the facility load R, which is predetermined among the facility loads R, can be monitored by the telephone line system control monitor unit 9. That is, when the monitor command button of the telephone line system control monitor unit 9 is operated, the interrupt signal INT
Is sent from the telephone line control monitor unit 9, and after this interrupt request processing is performed, the monitor request data is returned to the HBC1 as a reply signal RT, and the display data is sent from the HBC1 by the transmission signal VS based on the reply signal RT. It is possible to transmit to the telephone line system control monitor 9, operate the voice synthesizing circuit 907 under the control of the microcomputer 901 based on this display data, and generate the speaker 912 by voice message about the operating state of the corresponding equipment load R. You can do it.
Similarly, in addition to the equipment load R, it is also possible to set security alarms, monitor resets, and monitor the control state of the electric lock 18.

The telephone line system control monitor unit 9 is provided with operation buttons for controlling a specific equipment load R or an electric lock 18 and for setting and resetting a security alarm. When the operation buttons are operated, the operation of the remote control switch 16 is performed. Equipment load R as in the case
Alternatively, control of the electric lock 18 is performed, and in the case of setting and resetting the security alarm, the same operation as the above-described security alarm set and reset is performed. When these controls, set, or reset are performed, the control data for turning on the display lamp provided on the corresponding remote control switch 16 or the like is sent to the HBC1.
Is transmitted, and the display data is transmitted to the telephone line system control monitor unit 9 to be monitored by a voice message.

By the way, the telephone line system control monitor unit 9 controls the equipment load R and the electric lock 18, sets and resets the security alarm on the telephone outside the system, and sets so that the state can be monitored. set is able to perform the teleconverter set switch SW ₀ that is provided to the unit 9. In other words, when the tele-conset switch SW ₀ is set, the indicator lamp of the set display is turned on by exchanging data with the HBC 1,
At the same time, the telephone line system control is set.

When Thus to have calls from a push button telephone set from the outside of the system, HBC1 telephone to the telephone outside line l ₁ a or l ₁ b extension
through l ₁ a or l ₁ b for connecting the telephone line system control monitor unit 9. At this time, when the personal identification number is transmitted, it is taken into the microcomputer 901 through the DTMF receiver circuit 905, and it is determined whether the personal identification number matches the personal identification number registered in the internal RAM of the microcomputer 901. To HBC1 as a reply signal RT HBC1
Control code sent from outside the system is subsequently received by the DTMF receiver circuit 905 and returned to the HBC1 in the same manner as the password, and if the control code is a predetermined control code, the HBC1 is based on the control code. The control of the corresponding equipment load R or the electric lock 18 or the setting or resetting of the security alarm are performed. At this time, the voice message signal of the voice synthesizing circuit 907 is transmitted to the telephone external line l ₁ a or l ₁ b connected through the telephone extension l ₃ a or l ₃ b, and the control state can be monitored in the connected telephone. Of. The present system is configured so that the setting and resetting of the automatic notification in addition to the setting and resetting of the security alarm can be performed in the same manner.

Normally, telephone line system control is performed by a control code from a telephone outside the system. In this system, however, the test switch SW ₄ is provided to the telephone line system control monitor unit 9.
The has established, the test switch SW ₄ is to be operated interrupt request signal INT is sent to the unit 9 from HBC1, will be returned to the interrupt processing after the test request data, HBC1 receiving this test request data each telephone 3 and 4 ₁ ..., make a connection by transmitting the transmission signal VS of the connection control data to connect through the 24 and telephone line system control monitor unit 9 telephone extension l ₃ a or l ₃ b. Thereafter, when a predetermined control code is input from the telephone whose handset has been lifted by operating the push button dial, data transmission between the telephone and the telephone line system control monitor unit 9 is performed via the HBC1, and the system is out of the system. Monitor and control in the same way as the telephone set of This test mode can be released by operating the test switch SW ₄ again. By this operation, the same interrupt processing as at the time of the test request is performed, the connection state is released, and the original state is restored.

Next, the control of the electric lock 18 will be described. The electric lock 18 is controlled similarly to other equipment loads R, and the operation of the electric lock operation switch 19 is monitored by ordinary polling. When the door is closed and automatic locking is performed, the automatic locking data
It is returned to C1 as a reply signal RT and further transmitted from HBC1 to electric control unit 14 by transmission signal VS.
The electric lock control unit 14 receiving the VS returns the data indicating that the alarm state has been entered, the lock state data and the state display data to the HBC1, and the HBC1 sends the respective data to the operation switch 19
The signal is transmitted by the transmission signal VS, and the display is performed by the display lamp provided on the operation switch 19.

Then, when the operation switch 19 is operated, the operation data is transmitted to the HBC1 by an interrupt request, and the HBC1 sends this data to the electric lock control unit 14 to unlock it, and further returns its status data and status display data. , HBC1 transmits this data to the operation switch 19 side in the same manner as at the time of automatic locking, and performs unlocking display. Note that unlocking and locking can also be performed by telephone line system control, and the control data at this time is based on the reception control code from the telephone line system control monitor unit 9 based on the HBC1.
Is transmitted to the electric lock control unit 14.

When the electric lock 18 is unlocked due to destruction or the like in the above alarm state, the electric lock control unit 14 issues an alarm, and at the same time, sends operation data to the HBC 1 in the same manner as at the time of the detection operation of the sensor 11 and outputs an alarm. Of course, an alarm can be issued.

The electric lock control unit 14 has a secret switch
When the secret switch 25 is connected and the same number as the preset password is input by the secret switch 25, the microcomputer 1411 of the electric lock control unit 14 determines this match and unlocks or locks. I can do it. Of course, the secret code can be set in the built-in RAM of the microcomputer 1411 by the keyboard of the secret switch 25.

In this system, the password of the telephone line system control, the telephone number of the automatic report destination, the home telephone number to be sent out as the message for automatic report, and the setting of speed dial
It can be set with 3, 4 ₁ …, 24 push button dials and operation buttons for other functions. The operation is based on the setting method of the abbreviated dial described above, and the operation buttons for the functions used are different. Only.

By the way, such registration data is registered in the RAM 103 of the HBC1 and the registration data relating to the automatic notification is stored in the built-in RAM of the microcomputer 801 of the parent alarm unit 8, and the personal identification number of the telephone line control is stored in the telephone line control monitor 9. It is designed to be registered in the built-in RAM of the microcomputer 901.
