The latter consists of a mode signal M2, and these return signals RT are shown in FIGS. 11(a) and (b).
), a current mode pulse signal is returned at a change in the logical value signal waveform determined by the pulse width, α.

As shown in Fig. 12, the transmission signals vs, , vs, have logical values set by pulse widths, and are transmitted as bipolar baseband signals. 'lL''[ can be obtained.

First, in constant polling, the terminals corresponding to page 1 are sequentially accessed using the transmission signal S1 shown in FIG. 9(a).

At this time, HBCI sends an external telephone line l, connection tff! i, door phone information, and connection information for telephone extensions 1xa-13b are transmitted at regular intervals. Furthermore, an emergency button switch is provided for a telephone 3, child 211 story W15. ..., child phone fi24 with Picto TV, and sensor connection unit/ ) 1
3. Furthermore, parent alarm unit 8, child alarm unit 1
5 in sequence to return information on the status of each emergency button switch.

In such a normal state, if the operation button for making an outside call on the master telephone 3 (or slave telephone W15..., 24) is operated after 7-/up is performed, the operation is activated through the key scan lamp circuit 306. The signal is my computer 3
01, the interrupt signal INT is sent to the signal transmission line 12 in current mode through the data transmission circuit 302.

If the terminal issuing the interrupt is a fixed-length terminal, the timing for transmitting the interrupt signal is when the 81st pulse of the end signal EN is received, as shown in Figure 13(a), and if the terminal is a variable-length terminal, the timing is the timing for transmitting the interrupt signal, as shown in Figure 13(a). As shown in b), the start signal S
This is when the 81st pulse of Y is received, and the above-mentioned interrupt timing for making an outside line call is performed at the former time. Now, when the interrupt signal INT is sent and HBCl is received via the data transmission circuit 105, the CPU 101 stops the polling due to this interrupt, and performs an address search terminal based on the chart 70 shown in FIG. Perform access.

In other words, each terminal is accessed by changing the mode signal of the transmission signal S to polling for interrupt address search. This access causes the interrupting terminal to return the address. In this case, by pre-allocating the 7 addresses of the terminals to each group, the address search can be carried out by calling each group (common high-order bit address) and sending back the low-order bit address data when replying. (can do.

By this address search, it is determined whether the terminal belongs to page 0 or not. If the terminal that issued the above-mentioned interrupt does not belong to page O, then HB C1 changes the mode to a monitoring mode in which it further checks the interrupt flag and determines whether it is a long 7-mat transmission or a) 7-mat transmission. If the interrupt flag IRQ is 1 in the returned data from the terminal, it is determined that an interrupt has been requested, and if the returned data is "FF",
HBC using the transmission signal S2 of the long 7 mats and the transmission signal Sl of the sheet 7 mats in other cases.
l accesses the terminal at the address.

Now, 5 of the external line connection from the above-mentioned main phone 3! Upon request, an interrupt occurs as described above, and when the interrupt is confirmed, HBCI accesses the main phone 3 in the interrupt flag clear mode to clear the interrupt flag IRQ, and then connects the external #l connection from the main phone 3 to the above. Receives the requested data. Upon receiving this request data, the CPU 101
is a transmission signal having control data that connects the outside telephone @ 1, * or Lb, and connects the circuit network circuit 312 to the vacant telephone extensions l, a, or telephone extensions b to the main telephone fi3 along with this connection. ■HBCl transmits S. This connection is made by the action of the microcomputer 301 in the main phone 3, which lights up the display lamp 7α through the key scan lamp circuit 306 to indicate an outside line connection, and also transmits the dial tone to the circuit network circuit 312 and the relay contact r55. The sound is emitted from a speaker 318 through a coupling transformer 313, a mixing circuit 314, and an amplifier 316. Next, when the dial operation button of the main telephone 3 is pressed, an interrupt similar to the above-mentioned interrupt request is performed, and the operation dial data is returned from the main telephone fi3 as a reply signal RT.

The HBCI that received this operational data uses the microcomputer 101 to convert the dial to 7-11.
1 is activated to make an outside call. By reversing the polarity of the line, the collision prevention circuit 109 detects that the handset of the selectively connected telephone of the other party has been picked up by this outside line call and the telephone is in a talking state, and upon detection of this outside line calling state, an automatic notification interrupt is generated. CPUl01 performs a control operation so that it is not performed under the detection state of an outside line call state even if there is a call state.After entering this call state, the HBCl
resumes normal polling operations.

This outside call from the main telephone 3 can be made in the same way with the two pre-charged telephones 5°... or 24, or even with the single telephone 6.

In addition, when using the one-touch dial unit 20 to make an outside call after the above-mentioned outside line is connected, it is sufficient to operate the operation button provided in advance in accordance with the telephone number of the other party.
When this operation is performed, the above-mentioned interrupt request operation is performed between the HBCl and the one-touch dial unit 20, and the data on the operation button is sent as the return signal R when transmitting the white door automation.
T is transmitted from the data transmission circuit 202 of the one-touch dial unit 20 under the control of the arithmetic processing circuit 201. The HBCl that received this reply signal RT has R in advance.
The CPU 10I reads out the data corresponding to the corresponding operation button of the one-touch dial unit 20 from among the speed dial data stored in the AM 103, and dials the dialer 111 using the dialer 111.
Or child phone If! s +..., 24), all you have to do is press the on-hook call operation button, and when this operation button is operated, the microcomputer 3
01 is connected in parallel to the hook switch H8° through the relay circuit 319, and αriz is turned on to connect the line and enable a dial tone to be emitted from the speaker 318. At the same time, the microcomputer 301 makes an outside call. A control processing operation is performed to enable the same operation as when the handset is picked up.

When an outside call is made with this on-hook condition and a connection is made to the other party's telephone, the user can pick up the handset as soon as the other party's voice is heard from the speaker 318 and a normal conversation can be made. If you want to stop this outside call, operate the vibration function again and the microcomputer 301 will turn off.
is determined and the line status is returned to the initial state, and HBCl returns to normal polling operation.

When the above-mentioned call on the main telephone 3 due to the outside call is terminated and on-hook is detected by the micro combiator 301 by the hook-switched IS2, the main telephone 3 sends a return signal RT to the HBCl side indicating the end of the call. to return to normal operating condition.

Then outside the phone llAl, a or 1. 16H through b
When the incoming call ε signal of z is sent, the corresponding incoming call detection circuit 108 of the HBCl detects this signal, and the CPU 101 of the HBCl sends the outside line gI notification to each telephone, 3.5 ．． ..., (24) and individual telephone Agebuta 7 as a simultaneous mode, each telephone 3゜5, .
..., activate the signal tone circuit 305.405 in (24) and Agebuta 7 for single telephone, and activate the amplifier 316.416.
Through the key scan lamp circuit 306, 406, a sound is emitted from the key scan lamp circuit 318, 418, 708.
, 706, the incoming call is indicated by blinking the outside line display lamp.

If the call rejection button is operated at this time, the microcomputer P stops the operation of the signal tone circuit in the telephone or standalone telephone adapter 7 on which the call rejection button was operated, and stops the ringtone. be able to.

Now, with the external #1 display lamp flashing, press any of the phones 3, 5. . . . (24) When the handset is picked up at 6, an interrupt request signal INT is sent from the telephone, for example an AM telephone, and the above-mentioned interrupt processing is performed.

After this interrupt processing is performed, data requesting an outside line connection is sent from the main telephone 3 to the HBCl by means of a reply signal RT.

When this reply signal RT is received, HBCl accesses the telephone @3 and connects the incoming telephone outside line IIa or 1. The circuit network circuit 310 is connected to the telephone extension era or MU b corresponding to b through relay contacts rff+z, r3+3, ", 1°, and a talking state is established.

When this call state ends and the handset is returned to go on-hook, the telephone 3 issues an interrupt request again, and end-of-call data is returned to HBCl as a reply signal RT, and upon reception of this reply signal RT) (BCl opens relay contact r112 to perform a cycle release, transmits control data to open the line when the telephone 3 is accessed, and opens relay contact iI.

By the way, if it is desired to temporarily put the outside line call on hold in the above-mentioned outside line call state, the user may operate the hold button on the telephone, for example, the main phone fi3.

That is, when there is a hold operation, the telephone set 3 sends out an interrupt request signal rNT, and after the above-described stabilization process is performed, the telephone set 3 sends the hold request data back to the HBCI as a reply signal RT. When this hold request is received, the connected external telephone line La, f, or b is closed via a resistor, etc., and the corresponding hold circuit 110 is operated to connect the amplifier 113, the coupling transformer 114, and the relay contact ``...
to send the hold music to the other party. Control data is then transmitted to the telephone set 3 to open the line and control the blinking of the display lamp 2 of the outside line display, thereby causing the line to be opened and the display lamp to blink. At this point, if the handset of the telephone 3 is turned on-hook, the telephone is placed on hold.

Next, in order to release the hold state, all you have to do is operate the hold button again, and this operation causes the telephone 3 to send an interrupt request signal INT, perform the above-mentioned interrupt processing, and return the data for connection #a. It is sent out as signal RT. The H B C1 that received this return signal RT
At the same time as canceling the connection, line connection control data is transmitted to the telephone set 3, returning to the call state before being put on hold, and canceling the hold state.

In addition, every time the hold state elapses, the HB
When accessing the telephone 3 that has been set on hold, the CI activates the signal VT306 to make the speaker 318 emit a hold warning tone to alert the user that the phone is on hold. It is also possible to make an extension call while on hold.

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

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

First, use any phone Wi 3-4 +..., (24)
When the operation button for speed dialing is operated according to the speed dial setting procedure, an interrupt request signal INT is sent from the telephone, for example, telephone 3, and the above-mentioned interrupt processing is performed, and the telephone 3 sends the short registration request signal INT. −
The data is returned to HB C1 as a reply signal RT. Upon receiving this reply signal RT, the HBCI transmits abbreviated registration permission data to the Mfi telephone 3 in question. In the telephone 3 that has received this abbreviated registration permission data, the microcomputer 301 works to output a sound signal indicating permission of abbreviated registration from the signal tone circuit 305 and emit it from the speaker 318. After this ringing, when the shortening operation button is operated from the telephone set 3, an interrupt request signal INT is sent from the telephone set 3, and the above-mentioned interrupt processing is performed. After this interrupt processing, when the corresponding speed dial button data and registered telephone number data are returned as a reply signal RT from the telephone 3, the HBCl that received this data writes it into a predetermined area of the RAM 103 based on this data. It is.

This speed dial registration can be repeated continuously until the operation button indicating termination is operated, and when the operation button indicating termination is operated and the data is returned from the phone W13, HBCl registers the speed dial. Upon reception of the reply %RT, control data indicating the end of short registration acceptance is transmitted.

The master telephone 3 that has received this data causes the speaker 318 to emit a sound indicating the end under the control of the micro combiator 301 in the same manner as when the registration is permitted.

In accordance with this speed dial registration, dial registration corresponding to each operation button of the want/chidial unit 20 described above is completed.

Next, calls between extensions will be explained.

For an extension call, for example, when calling the slave phone 41 from the base phone 3, first pick up the No. 1 handset of the base phone 3, press the dial button corresponding to the extension phone number, and by this pressing operation the call is made from the base phone 3. Included signal IN
T is transmitted to HBCI, and H is transmitted by the above-mentioned interrupt processing.
Data of an extension connection request is returned from the telephone 3 upon access from the BCl. Upon reception of this reply signal RT, in II B C1, the communication path switch circuit 116 operates the communication current supply circuit 117, and the circuit 7 is connected to the vacant telephone @ 1-a or f3b at the relay contact r.
114, and at the same time transmits the transmission signal ■S from the slave phone 4-HBCl on the called side and sends the signal a times M.

All telephones 4 except the calling party's master telephone 3.

24, a transmission signal vS is transmitted that causes an extension call indicator lamp to blink. *The calling party's parent phone? l! 3
, the extension call indicator lamp flashes and the network circuit 312 is connected to the predetermined telephone extension A or LYB.
are connected through relay contacts ", 1□, r31, and r315. Control data is transmitted from HBCl by a transmission signal ■S, and the main telephone 3 is connected to the extension line.

After connection #a is completed, when the push button dial is released, the interrupt request signal INT is sent again to telephone a 1) HBCI, and after this interrupt processing, the dial push from the main phone fi3 ends. Data is transmitted to HBCI.

Based on this data, the HBCl sends the called slave telephone 4. Control data for stopping the generation of the call notification sound is transmitted by the transmission signal ■S to stop the generation of the call notification sound.

At this point, when the handset of the slave telephone 41 on the called side is picked up, an interrupt request signal INT is transmitted from the telephone 41 to the HBCI, and after this interrupt processing, response data is transmitted as a reply signal RT. The BC that received this response data called W14. Similarly to the main telephone 3, control data for extension connection is transmitted using the transmission signal vS to the telephone 4. network circuit 412
to the predetermined telephone extension exa or 1. Connect to b.

With the above connection, calls can be made between extensions.

In addition, in the case of an extension connection, there is a simultaneous ringing mode, and in this case, the button dial that is preset for simultaneous ringing on the calling party's telephone can be used instead of the button dialing for individual calling described above. All of the other telephones become called telephones, and the above-mentioned ring tone is announced on all of these telephones W1, and between them and the telephone of the called party who picked up the handset first. It is now possible to make calls,
The same control processing as for individual call I is performed except for the notification control of the ringing tone.

Also, when the extension call state is entered, each telephone 3-4 +...
.

Control data is transmitted from the HBCI by the transmission signal ■S so that the extension call indicator lamp lights up in the 24 or 21 Sandoku telephone adapter 7, and the extension call status is displayed by lighting the indicator lamp. Become. During this display, even if there is a request for individual extension connection, HBCI
acts as if it does not accept the request. However, if there is a simultaneous call request during this display, the HBCI operates so as to stop the current call that is connected after connection #a and give priority to the simultaneous call.

Dog with doorbell 2? l! Leap phone calls with the handsets 3, 4, . . . , 24 will be explained.

First, in the case of a call from the door phone 2, when a call signal from the door phone 2 enters the HBCI through the door phone interface 7S 106, the HBCI is sent to the communication path switch circuit 11.
13.4, the call current supply circuit 117 is operated by 6, and the call current is supplied to the telephone extension A or LSB through the relay contact ``,'', and the door phone information is transmitted to each telephone.
, ..., 24 or the transmission signal V to the standalone telephone adapter 7
A signal tone circuit 305 is transmitted by S, and is provided in each signal tone circuit 305.

It is operated under the control of ..., Subie fJ318,41
8... The chime sound is emitted and the display lamp of the doorbell display goes off to indicate that there is a call from the doorbell 2.

When the handset of one of the telephones is picked up due to this call, telephone extension 1. Connection is made through a, l, and b, and a call state is established, and at the same time, control data for switching the blinking of the above indicator lamp to lighting is transmitted from the HBCI to each telephone 1'! 3.4. ....

24, and the respective display lamps are lit.

Next, when calling the doorbell 2 from the phone fi 3.4,..., 24 or 6, pick up the handset of the phone, press the doorbell button provided on the phone or Agebuta 7, and the call will be made under the control of HB C1. , a connection is established with the doorbell, and calls can be made.

Furthermore, if the doorphone 2 is set to multiple levels and there is a call from another doorphone while a call is being made to one doorphone, by pressing the doorphone button, the telephone can issue a connection request to the other doorphone to HBCl. can. Furthermore, if there is a doorbell call and an incoming outside line call at the same time, the HBCl gives priority to the incoming outside line call and connects the outside line to the telephone whose handset is raised. Furthermore, when a doorphone call is received during an outside line call, by operating the doorphone button, a connection request to the l'7 phone 2 and a request to hold the outside line are sent back to the HBCl, and the call can be made to any door phone 2 and the outside line is put on hold. This request to release the outside call hold can be made by shaking the doorbell button again. Further, if a doorphone call is received during an extension call, a connection request to the doorphone 2 can be made by pressing the doorphone button. In this case, the extension call is stopped. Also phone R3*
4 +...

If you make a doorphone call from 24 and press the button dial corresponding to the doorphone number set on doorphone 2, the doorphone number data will be sent to the HBC along with the connection request.
I, and the corresponding door phone 2 can be called. If there is no movement of the dial, HBCl selects and connects the door phone 2 that was last used. By repeatedly pressing the call rejection button, you can restrict the chime sound.

Next is the 'IL story F of this system! 13,4. ..., 24
Each unit 9 is equipped with microphones 317, 417, etc. for collecting sounds from a certain room, so that a so-called room monitor can be performed.

In other words, the telephone in the room you want to monitor, for example, slave telephone 41.
When the handset of 4. is lifted and the monitor setting button is pressed, the child phone 4. An interrupt request signal INT is sent to the HBCI from... Then, when the handset is returned and the stabilization request is processed, the monitor mode data is transferred from the child phone 41 to the HB.
A reply signal RT is sent back to the CI, and the HBC1 that has received this reply signal RT transmits data indicating that the reception has been received to the slave N packing machine 41 using the transmission signal VS, and the slave phone 41 The indicator lamp on the monitor display blinks under the control of the microcomputer 401, and the corresponding child phone P!
Displays that i41 is set to the monitored side.

Next, when the monitor setting button is pressed on the monitor side telephone, for example, the master telephone 3, data is exchanged with the HBCI in the same manner as the above setting, and the display lamp of the master telephone 3 is turned on. After this lighting, each phone 4. ．．

14. Can it be reproduced and monitored by the speaker 318 through the amplifier 316? I will be able to do it.

If you want to end this monitor, use the main phone 3 on the monitor side.
All you need to do is create four room monitor buttons, and after receiving the interrupt request signal INT resulting from the fabrication of the room monitor button and processing the interrupt, the HBCI receives and receives the monitor termination request data from the base phone 3. transmits the control data for terminating the monitor connection to the telephone 3 or 4 on the monitored side and the monitor side. and terminates the connection to the monitor 411.

In addition, for the above-mentioned monitoring operation, outside calls and internal calls take priority, and when these calls occur, room monitoring is automatically suspended, and H is set to resume monitoring after the call ends.
BCl controls the terminal side.

The above-mentioned operations were call-related control operations, but next, security-related operations will be explained.

First, the sensor connection unit 13 is sequentially accessed using the transmission signal vS in the monitoring mode by normal polling,
Various sensors 11 are connected to each other by accessing them.
The monitoring data is sent back as a reply signal RT, and the monitoring data is transmitted to the parent alarm unit 8 using a transmission signal S in the control mode. Here, if an abnormality is detected in the sensor 11, the parent alarm unit 8 sends the voice synthesis circuit 80
9 and the signal tone circuit 805 are connected to the microcomputer 801.
It operates under the control of the sensor, generates an alarm sound signal and a message signal according to the detection sensor, and makes them sound from the speaker 815. At the same time, an interrupt request signal INT is sent to the HBCI, and after the interrupt processing, the abnormal alarm is transferred. data to HB
The parent alarm unit 8 returns a long acknowledge signal RT to the CI. When the HBCI receives this reply signal RT, each 'FIL talk fi that has a speaker for alarming
3, 4°, . The control data for connecting the extension telephone 1 to B and further transmitting the control data for connecting the alarm sound signal and message signal to the internal telephones 13 m, l, and b to the parent alarm unit 8 using the transmission signal ■S, and transmitting the alarm sound signal and message signals to each telephone FM3.4, ..., 24 and individual telephone adapter 7 through telephone extension lines 12m or β, b.
and causes the respective speakers 318, 418, and 718 to emit an alarm sound and a message.

In addition, when the notification set button is set, 18c1 calls the telephone number of the automatic notification destination, which has been stored and set in advance in the built-in memory and RAM 103 of the microcomputer 801 of the unit 8, and the notification is made here. When the alarm is started, a display lamp for displaying a report is lit in the main alarm unit 8.

And ′ outside the system? The response detection circuit 8 detects that the line polarity has been reversed due to the pick-up of the fL handset.
When 08 is detected, the parent alarm Uni? ) 8 under the control of the microcomputer 801, a message signal for notification is output and the message is sent! 1, and the display lamp changes from blinking to lighting. This message is simultaneously emitted from the speakers 318, 418, 708 of each telephone set 3, 41, .

The number of messages to be sent is predetermined, and when that number of messages are sent, the next automatic notification destination is switched. Furthermore, if the destination of the report does not respond, the notification will be repeated a predetermined number of times by re-gialling.

Furthermore, the HBC 1 performs a control operation so as not to interrupt or stop this automatic notification even if the sensor 11 no longer detects it during the process.

If the handset of telephone 3-4+..., 24 or 6 is picked up during this call and the outside line connection button is pressed, the automatic call will be interrupted under the control of HBCI and the call with the other party will be prioritized. When the line connection was established and the call was terminated, subsequent notifications occurred and the above-mentioned alarm was issued! !
! Connected to the sensor connection unit 13, data for controlling the alarm ringing of the emergency bell 27 is sent back from the parent alarm unit 8 as a reply signal RT, and the HB
The emergency bell 27 connected to the sensor connection unit 13 is sounded under the control of the arithmetic processing circuit 131 by the Cl transmission signal S.

Furthermore, the main alarm unit 8 sends an interrupt request to the HBCl to connect the call line 1. of the door phone 2. connection is made, and the alarm sound and message notification are performed from the speaker of the door phone 2 until there is a response to the automatic notification.

By the way, the above operation has been explained with respect to the detection operation of the sensor 11, but the sensor connection unit 13 or -1 is connected to the telephones 3 and 4.
1..., 24 or the emergency button switch provided on the standalone telephone adapter 7, an interrupt request signal I'NT is output, and after the interrupt request is processed, an emergency button is sent to the main alarm unit 8. Button switch mechanism data is HB
The signal is transmitted by the transmission signal vS from Cl, and from then on, alarms and automatic notifications are issued in the same manner as during the detection operation of the sensor 11 described above. Furthermore, when the emergency button switch of the main alarm unit 8 is operated, transfer data is returned from the main alarm unit 8 to HBCl by an interrupt, and from then on, the above-mentioned sensor 1
The same processing as in the case of the first detection operation is performed.

Here, the above-mentioned automatic notification setting is performed by setting the notification set button of the parent alarm unit 8.
Since the operation of the emergency button switch is more reliable than the sensor 11 made by WA#J, the switch SWl that sets automatic notification only when the emergency button switch is operated even when the notification set button is not set is installed in the parent alarm unit 8. is provided, and when the parent alarm unit 8 returns the transfer data to HBCl, it returns the setting data of this switch SWI along with the data of the automatic notification setting, and the HBCl determines whether or not to perform automatic notification. It is supposed to be done. Therefore, if the switch S W + is turned on, an automatic report can always be made when the emergency button switch is activated.

By the way, the detection operation of the security sensor of sensor 11 is only effective when the security alert is set.
The security sensor 11c can be set and reset by using the telephone port #i system control described later, or by installing it in the parent alarm unit 8, the child alarm unit γ) 8m that does not have a function related to automatic notification of the parent alarm unit 8, or the sensor connection unit. This can be done by operating switch SW2.

Child alarm unit) 8m or the operation data of the switch SW2 of the sensor connection unit 13 is requested for an interrupt at the time of shaking, and after processing the interrupt, it is transmitted to HBCl, and then the H
The parent alarm unit 8 is activated by the transmission signal VS from BCl.
After receiving this transmission signal vs, the display data is returned to the HBCI by an interrupt request from the rear view alarm unit 8, and the control data from the HBCI is transmitted to the sensor connection unit 13 and the child alarm unit (8m). Turns on the warning set and reset indicator lamps. Of course, when the switch SW2 of the parent alarm unit 8 is operated, the operation data is transmitted to the HBCI mentioned above.

Sounding an alarm when the security is set is effective when you are at home, as it intimidates intruders, but if you are not home, you will lose the opportunity to catch the intruder, so the main alarm unit 8 will be notified by 11. ′? ! A switch SW is provided to regulate the alarm.

When this switch SW is turned on, the parent alarm unit 8 sends data to the tlBct side to stop the alarm issuing within the system. S-den 71II generation 3,4□2
4 and Agebuta 7 for single phone subhi h318°418
and 708 extension connection control.

Therefore, it is possible to automatically notify the outside of the system without the intruder noticing, and it is possible to capture the intruder.

Here, the above-mentioned automatic notification is outside the telephone fi11a, /, IJ
This cannot be done if Mα is occupied by a call from outside the system, so in this system, first call Mα outside the free phone.
The CPU 101 of the HB C1 determines whether or not the call detection circuit 108 detects an incoming call 1a, Q, or b, and if there is an open outside telephone line, the above-mentioned automatic notification is performed using that outside telephone line. Sky again! 1. If there is no external telephone line, a message is sent to a pre-determined high-priority external telephone line, and when the message reporting is completed, the line is forcibly opened and calls to the other party are stopped. The above-mentioned automatic call is made using an outside telephone line. In this way, even if an intentionally connected external telephone line is ringed by a telephone outside the system and the line is blocked, automatic alarms can be issued reliably, increasing the reliability of the system. It is possible.

Moreover, when the above-mentioned sensor 11 or the emergency button switch is activated, the handset is picked up, and the telephone 3, 4I.
..., 24 or standalone phone adapter 7 Subi 1J3
18,418.708 is connected to the network circuit 312.412 side or disconnected from the telephone 11i 13 a or lsb, so the alarm sound and message from the parent alarm unit 8 are not reported. In the HBCI, signal tone circuits 305 and 4 are provided for those in a talking state.
05,705 is sent, and a sound signal from the signal sound circuit 305.405.705 is used to emit an alarm sound, thereby making it possible to prevent false alarms.

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

First, the camera switching unit 22 turns on the monitor television camera 21 attached to the door phone 2 in conjunction with a call 1 from the door phone 2, and displays an image on the monitor television 23. In other words, when there is a call signal from the doorbell 2, HBCl transmits control data to the camera switching unit 22 using the transmission signal vS, turns on the corresponding monitor television camera 21 connected to the camera switching unit 22, and simultaneously switches the monitor Control data for starting the operation is also sent to the television 23 using the transmission signal vS, and the monitor television 23 is operated. With this operation, the video signal near the doorbell 2 is sent to the monitor TV 23 through the coaxial cable l.
The video will be sent to and displayed on the screen.

Here, the monitor television 23 is mounted in multiple stages, and each telephone set 3, 4
．． ..., if the serial I#I relationship is set in 24.6, first set HB to operate all monitor TVs 23.
The CI sends a transmission signal ■S, and then stops the operation of the monitor television 23 that does not correspond to the telephone from which the handset has been taken off, and displays the image only on the monitor television 23 that corresponds to the telephone that is talking to the doorbell 2, and the call ends. Then, a transmission signal S that stops the operation of the monitor television camera 21 and the operation of the monitor television 23 is transmitted to the camera switching unit 2.
2 and a monitor television 23.

When displaying images on the monitor television 23 without interlocking with the doorbell 2, it is recommended to set the monitor switch on the monitor television 23 to fi (S-).
It is returned to BC1, and after the interrupt request processing is completed, HBC
1 transmits control data for operating the corresponding monitor television camera 21 to the camera switching unit 22 by a transmission signal S, and operates the monitor television camera 21. After the monitoring is finished, if the monitor switch is operated again, the same processing as during operation is performed and the operation of the monitor television 23 and the one-monitor television camera 21 is stopped.

By the way, in this system, the monitor television cameras 21 are sequentially switched according to the detection operation of the security sensor 11e described above. In other words, when the above-mentioned alarm is issued, H
The BCI transmits control data for sequentially switching each monitor television camera 21 to the camera switching unit 22 as a signal ■S.
The video signals from each monitor television camera 21 are sequentially transmitted to the coaxial cable 1-. In conjunction with the operation of each monitor television camera 21, a transmission signal S is sent from the HBCI to each monitor television 23, so that images can be displayed on each monitor television 23, and the intrusion situation can be monitored.

The control of the equipment load R by the telephone line #l system *qlf and the multiplex transmission system will be explained in detail.

First, when the selector switch unit 9 or the remote control switch 16 is operated, an interrupt request signal INT is generated.
is transmitted to HBCI, and after this interrupt processing is completed, HBCI
Cl transmits control data to the relay control unit 10 to control the operated corresponding load R, and turns the corresponding load R on or off.

This ¥ + 1fiI load R includes predetermined equipment #
The control status of H can be monitored by the telephone line system control monitor unit 9. Ru. That is, when the monitor command button of the telephone line system control monitor unit 9 is operated, an interrupt signal INT is sent from the telephone line system control monitor unit 9, and after this interrupt request processing is performed, the monitor request data is sent as a reply signal RT. This reply signal RT1. :Based on this, the display data is transmitted from HBCl to the telephone line system control monitor 9 using the transmission signal ■S, and based on this display data, the micro combinator 90
1, the voice synthesis circuit 907 is operated under the control of the speaker 9, and the operating state of the corresponding equipment load R is transmitted to the speaker 9 by voice message.
12 can be generated. Similarly, in addition to the equipment load R, it is also possible to monitor the setting and reset of security precautions and the control status of the electric lock 18.

In addition, the telephone line system control monitor unit 9 is provided with an operation button for controlling a specific @ threat load R or electric lock 18, setting and resetting the crime prevention 'II commandment, and when this operation button is operated, the above-mentioned remote control switch is activated. The equipment load R or the electric lock 18 is controlled in the same manner as in the operation of 16, and setting and resetting of the security alarm are performed in the same manner as the above-mentioned setting and resetting of the security alarm. When these controls, sets, and resets are performed, the corresponding remote control switch 1
The HBCl transmits control data to turn on the display lamp provided in the telephone line #i, etc.
The signal is transmitted to the system fIIJ control monitor unit 9 and monitored by voice message.

By the way, the telephone line system control monitor unit 9 is set so that it can control the equipment load R and the electric lock 18, set and reset the security alarm, and monitor its status on a telephone outside the system. Setting can be performed using a teleconference set switch S Wet provided in the unit 9. In other words, when the telecon set switch SWo is set, HB
As a result of data exchange with C1, a set indicator lamp is lit, and along with this lighting, telephone line system control is set.

Therefore, when there is a call from a Boucher button telephone from outside the system, the HBCI will call outside the telephone @ 1, or 1
．． b to telephone extension lla or 1. A telephone line system control monitor unit 9 is connected via b. At this time, when the password is transmitted, it is taken into the microcomputer 901 through the DTMF receiver circuit 905, and it is determined whether the password matches the password registered in the built-in RAM of the microcomputer 901, and this determination data is further sent back to HBCI as a reply signal RT, and then an 8 control code sent from outside the system is received by the DTMF receiver circuit 905 and sent back to HBCI in the same way as the password, and HBCl is a predetermined control code. If so, the corresponding equipment load R or the electric lock 18 is controlled or the crime prevention alarm is set or reset based on the control hood. At this time, the speech synthesis circuit 907
The voice message signal in the telephone IIA 1 core a or l
The signal is sent to the external telephone line 11 & or 1+b connected through the sb, and the control status of the connected telephone can be monitored. In addition to setting and resetting crime prevention alerts, this system is configured so that automatic notifications can also be set and reset.

Normally, telephone line system control is performed using an I/O from a telephone outside the system.
In this system, a test switch S is installed in the telephone line system control monitor unit 9.
W4 is provided, and when this test switch SW4 is operated, an interrupt request signal INT is sent from the unit 9 to H.
After processing the interrupt, the test request data will be sent back to the BCI, and the HBCl that received the test request data will send it to each telephone set 3, 41, .
The system control monitor unit 9 is connected to the telephone extension MU a or 1. A connection is established by transmitting connection control data using a transmission signal vs. Data is transmitted between the telephone and the telephone diagram #I system control/monitor unit 9, allowing monitoring and control in the same way as a telephone outside the system. This test mode can be canceled by operating the test switch SW4 again, and 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 returned.

Now, to explain the control of the electric lock 18, the electric lock 18 is controlled in the same way as other equipment loads R.
The operation of the electric lock operation switch 19 is monitored by normal polling, and when the door is closed and automatically locked, automatic locking data is returned from the operation switch 19 side to the HBC 1 as a reply signal RT. , and further HB
A transmission signal ■S is transmitted from the CI to the electric control unit 14, and upon receiving this transmission signal VS, the electric lock control unit 14 receives data indicating that it has entered an alarm state, key status data, and its status! ! ! Return display data to HBCl,
BCl transmits each data to the operation switch 19 as a signal ■
The information is transmitted by S and displayed by an indicator lamp provided on the operation switch 19.

When the operation switch 19 is operated, the operation data is transmitted to the HBCI by an interrupt request.
sends this data to the electric lock control unit 14 to unlock it, and also sends back the status data and status display data, and the HBCI transmits this data to the operation switch 19 side in the same way as when automatically locking, and displays the unlocked lock. have them do it. Note that unlocking and locking can also be performed by telephone line system control, and the control data at this time is transmitted from the HBCl to the electric lock control unit 14 based on the received control code from the telephone line system control monitor unit 9.

When the electric lock 18 is unlocked due to destruction or the like in the above-mentioned alarm state, the electric lock control unit 14 issues an alarm, and at the same time sends operation data to the HBCl in the same way as when the sensor 11 detects the operation. Of course, a notification can be issued.

・A secret switch 25 is also connected to the electric lock control unit 14, and this secret switch 2
When the same number as the password set in advance by 5 is input, the microcomputer 1 of the electric lock control unit y) 14
411 can unlock or lock the door by inferring this match. Of course, the password can be set in the built-in RAM of the microcomputer 1411 using the keyboard of the secret switch 25.

Now, in this system, the pin number for controlling the telephone line system, the telephone number of the automatic report destination, the home telephone number sent as a message at the time of automatic report, and the speed dial settings are
! 3.4 l... can be set using the 24 button dials and the other 7 operation buttons, and its mechanism is based on the speed dial setting method described above. The only difference is the stirring action for the anxane a.

By the way, such registered data is stored in RAM10 of HBCI.
3, the registration data related to automatic reporting is stored in the BRAM of the microcomputer 801 of the parent alarm unit 8, and the password for telephone line system control is stored in the jlR of the microcomputer 901 of the telephone line system control monitor 9.
It is now possible to register AMl.

If this registered data is erased due to a power outage or other trouble, this system will display the following message. In addition, in case of short-term power outages such as instantaneous power outages, this system uses a large capacity capacitor C0 to
The power supply of 3 is backed up so that the registered data on the HBCl side cannot be easily deleted.

In other words, in unit 8 or 9, check the registered data in your own ilRAM! jS15 This is performed at regular intervals as shown in the diagram, and if this registered data has not been deleted, the process is transferred to normal processing. If the registered data has been erased, an interrupt request is made to request the HBCl to transfer the corresponding registered data, and at the same time, a built-in timer is set. If transferred, the registered data is registered in the fiRAM of each unit 8 or 9.

If no registration data is transferred after timeout, HBC
It is determined that the registered data in RAM 103 of 1 has also been erased, and the respective microcomputers 801 or 901
Under the control of the controller, the display lamps provided in the husband units 8 and 9 flash and enter a registration waiting state.

The user who sees this flashing can register the registered data erased using the operation buttons 3, 41, 24 of the telephone using the above-mentioned speed dial registration capacity (by this registration, the HBCl When the data is stored in the RAM 103, the data corresponding to units 8 and 9 is transferred from the HBCI to the respective units 8 and 9 by the transmission signal S, and is registered in the internal RAM of each microcomputer 801 and 901. , the blinking of the above-mentioned indicator lamp is stopped.
