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 out and HBCI is received via the data transmission circuit 105, the CPU 101
l) The above polling is stopped due to the input, and terminal access for address search is performed based on the flowchart shown in FIG.

In other words, the mode signal gi-tx of the transmission signal Sl is replaced with the polling of the address search to access each terminal. This access causes the interrupting terminal to return the address. In this case, by pre-allocating terminal addresses for each group, it is possible to speed up the address search by calling in groups (common high-order bit addresses) and sending back the low-order bit address data when replying. can.

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 0, then HBCl changes the mode to a monitoring mode in which it further checks the interrupt flag and determines whether the transmission is long 7 format transmission or short 7 format transmission. If the interrupt flag IRQ in the returned data from the terminal is 1, it is determined that an interrupt has been requested, and if the returned data is "FF"l,
HB using long 7-ohm transmission signal ■S2, otherwise short 7-ohm transmission signal ■S1
C1 accesses the terminal at that address.

Now, the above-mentioned parent phone! There is a request for external line connection from f13 and an interrupt is generated as described above.When the interrupt is confirmed, HB C1 accesses the main phone 3 using the interrupt flag courier mode, clears the interrupt flag IRQ, and then clears the interrupt flag IRQ. The connection request data is received from the above external #a. From receiving this request data, the CPU
i o 1 is an outside telephone line f, a or! lb is connected, and with this connection, the free telephone extension ff is connected to the main phone 3.
The HBCI transmits a transmission signal S having control data for connecting the network circuit 312 to the network circuit 13a or the telephone extensions t and b. This connection is made to the key scan lamp circuit 3 by the 1111 of the micro combiator 301 in the main phone 3.
At the same time, the display lamp indicating the external line connection is lit through 06, and the beep is connected to circuit w4 circuit 312 and relay contact r.
77. , a coupling transformer 313 , a mixing circuit 314 ,
The sound is emitted from a speaker 318 via an amplifier 316. When the dial operation button of the main telephone 3 is then pressed, an interrupt similar to the above-mentioned interrupt request is made, and the operation dial data is returned from the main telephone 3 as a reply signal RT.

In the HBCI that received this operation dial data, the microcomputer 101's VIk! & causes the caller 111 to operate and make an outside call. Selected by making this outside call! On the connected other party's phone/1
The anti-collision circuit 109 detects that the handset has been disconnected and is in a talking state by reversing the polarity of the line, and due to this detection of an outside line call state, even if there is an automatic notification mr+, it will not be carried out under the detection state of an outside line call state. CPU
l01 performs a control operation, and after entering this talking state, HBCl resumes normal polling operation.

This external call from the main phone 8113 is sent to the slave phone 51...
・Or 24 or even a single telephone 6 can be used in the same manner.

In addition, when using the one-touch dial 22) 20 to make an outside call after connecting the above-mentioned outside line, it is sufficient to operate the operation button provided in advance according to the telephone number of the other party.
When this operation is performed, the above-mentioned interrupt request operation is performed in the dark between the HB C1 and the one-touch dial unit 20, and the data of the operation button is transmitted to the data transmission circuit 202 of the one-touch dial unit 20 as a return signal RT during short 7-ohm transmission. The data is transmitted under the control of the arithmetic processing circuit 201. When the HBCl receives this reply signal RT, the CPU 101 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 advance in the RAM 103, and dials out using the Guyara-111 to call the other party's phone. It calls.

Next, in the on-hook state, the main phone 3 (or slave phone 5,
..., 24), just press the on-hook call operation button, and when this operation button is operated, the microcomputer 301 is connected in parallel to the hook switch H8 through the relay circuit 319. At the same time, the microcomputer 301 detects an outside call and operates in the same manner as when the handset is picked up by turning on relay contacts r and 14 to establish a line connection and enable a dial tone to be emitted from the speaker 318. If you make an outside call while on-hook to perform control processing operations and are connected to the other party's telephone, when you hear the other party's voice from the speaker 318, you can pick up the handset and resume normal conversation. It will be possible to do it. If it is desired to stop this outside call, by operating the operation button again, the microcomputer 301 determines "off" and returns the line state to the initial state, and the HBCI returns to normal polling operation.

When the above-mentioned call to the main phone 3 due to the outside line call ends and on-hook is detected by the hook switch HS 2 in the microcomputer 301, the main phone 3 sends the end of the call back to HBCIm with a return signal RT to HBCl. Return to normal operating condition.

Next, call outside line NIa or 1. When a 16Hz incoming signal is sent through b, the corresponding incoming call detection circuit 108 of HBCl detects this signal, and
i o i transmits the outside line information to each telephone fi3.5, .
, (24) and the standalone telephone adapter 7 operate the signal tone circuits 305 and 405 to emit sound from the speakers 318, 418, 708 through the amplifiers 316, 416, and the key scan lamp circuits 306, 406, 7.
06, the outside line display lamp blinks to indicate an incoming call.

If the incoming call rejection button is operated at this time, the microcomputer of the telephone or standalone phone Agebuta 7 on which the incoming call rejection button has been operated can stop the operation of the signal tone circuit and stop the ringtone. can.

Now, with the external #1 display lamp flashing, select either phone fi3, fi5. . . . (24) When the handset is picked up at 6, an interrupt request signal INT is sent from the telephone, for example, the master telephone 3, and the above-mentioned interrupt processing is performed.

After this interrupt processing is performed, request data for external line connection is sent from the main telephone 1f13 to QHBCl by the reply signal RT.

When this reply signal RT is received, HBC 1 accesses the telephone 3 and calls the incoming telephone extension 11a or 1, b +: corresponding telephone extension 13m or 13b.
connect the circuit network circuit 310 to the relay contacts r312, r31ff
, r, 1° to connect and make a call.

When this call state ends and the handset is returned to go on-hook, the telephone 3 issues an interrupt request again, and the end of call data is returned to HBCl as a reply signal RT. opens relay contact rll□ to open the line, transmits line opening control data when the telephone 3 is accessed, and then opens relay contact rll.

1. Open.

By the way, if it is desired to temporarily put the outside line call on hold in the above-mentioned outside line call state, it is sufficient to operate the hold button on the telephone, for example, the main telephone 3.

That is, when there is a hold operation, the telephone 1913 sends an interrupt request signal INT, and after the above-described interrupt processing is performed, the telephone 1fi3 sends the data of the hold request back to the HBCl as a reply signal RT. When this hold request is received, the connected external telephone line 111A or 11b is closed via a resistor, etc., and the corresponding hold circuit 110 is operated to transmit the hold tone to the other party through the amplifier 113, coupling transformer 114, and relay contact r113. Send to. And the phone in question? ? At step 13, control data for controlling the opening of the line and the flashing of the indicator lamp indicating the outside line is transmitted, and the opening of the line and the blinking of the indicator lamp are performed. At this point, if the handset of the telephone 3 is turned on-hook, the telephone is placed on hold.

Next, to cancel 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 send the data of the line connection request to the return signal RT. Sent as .

Upon receiving this return signal RT, the HBCI releases the line connection, transmits line connection control data to the telephone set 3, returns to the conversation state before the hold, and releases the hold state.

In addition, every time the elapsed time of the pending state elapses, the HB
Cl activates the signal tone circuit 306 when accessing the telephone set to be on hold (f13) to emit a hold alert tone from the speaker 318 to alert the user that the phone is on hold. It is also possible to call.

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, when one of the telephones 1913-41, . The interrupt processing is performed, and the abbreviated registration request data is returned from the telephone 1'fi3 to the HBCI as a reply signal RT. Upon receiving this reply signal RT, the HBCI transmits the abbreviated registration permission data to the telephone bill 3. The telephone 3 that received this abbreviated registration permission data uses the microcomputer 3.
01, the signal sound circuit 305 outputs a sound signal indicating permission for abbreviated registration, and the speaker 318 emits the sound signal.

After this ringing, when the shortening operation button is operated from the telephone Ig13, an interrupt request signal INT is sent from the telephone Ig13, 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 to a predetermined area of RAMI 03 based on this data. .

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 telephone 3, the HBCI registers the speed dial. Upon reception of the reply signal RT, control data indicating the end of short registration acceptance is transmitted. The master telephone 3 that has received this data makes a sound indicating the end of the registration sound on the speaker 318 under the control of the microphone computer 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 one-touch dial unit 20 described above can also be performed.

Next, calls between extensions will be explained.

For an extension call, for example, when calling a slave telephone 8!4+ from the master telephone 3, the user first picks up the handset of the master telephone 3 and presses the dial button corresponding to the internal telephone number. As a result of this push operation, an interrupt signal INT is transmitted from the telephone 3 to the HBCI, and data of an internal M connection request is returned from the telephone 3 by access from the HBCI through the above-mentioned interrupt processing. Upon reception of this reply signal RT, the HBCI operates the call current supply circuit 117 by the call path switch circuit 116, and connects the circuit to the vacant telephone extension Z3a or l, b via the relay contact r114.
At the same time, the transmission signal VS is transmitted from the HBCI to the slave telephone 41 on the called side, and the signal tone circuit 305
Activate the phone W14. 4. The speaker 318 of the speaker 318 emits a call notification sound, and all telephones except the calling party's master telephone 3 are contacted. ....

24, a transmission signal S is transmitted that causes an extension call indicator lamp to blink. In addition, for the calling party's main phone 3, the extension calling indicator lamp flashes and the predetermined telephone extension is called! , a or lvb through relay contacts r5, 2, r, 11, ``, 1°'', control data is transmitted from the HBCI by the transmission signal S, and the main telephone 3 is connected to the extension line.

After this extension connection is completed, when the push button dial is released, a V'M re-interval request signal INT is sent to HB C1 from the base phone 3. Dial press end data is transmitted to the HBCI.

Based on this data, the HBCl sends the called slave telephone 4. Then, control data for stopping the generation of the call notification sound is transmitted by the transmission signal S, and the generation of the call notification sound is stopped.

At this point, when the handset of the slave telephone 41 on the called side is picked up, an interrupt request signal INT from the telephones R4 and #- is transmitted to HBCl, and after this interrupt processing, response data is transmitted as a reply signal RT. The BC that received this response data sends the control data for extension connection to the telephone 4I using the transmission signal V in the same way as the main telephone 3.
S to the telephone 4. The network circuit 412 is connected to a predetermined telephone extension 1ja or 13b+: afterward.

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 phone can be operated instead of the button button dialing for individual calling described above. All of the telephones on the telephone line become the telephones of the called party, the above-mentioned ringing tone is announced on all of these telephones, and a call is made with the telephone of the called party who picks up the handset first. The control process is the same as that for individual calls except for the notification control of the ringing tone.

Also, when the extension call state is entered, each phone number n3-41...
.

24, or the transmission signal from the HBCI when the extension call indicator lamp lights up on the standalone telephone adapter 7.
Control data is transmitted by S, and the extension call status is displayed by lighting the display lamp. During this display, even if there is a request for individual extension connection, the HBCI operates as if it does not accept the request. However, if there is a simultaneous call request while this display is displayed, the call using the current extension connection will be stopped, and the HB will be set to give priority to the simultaneous call.
The CI performs the action.

The call between the doorbell 2 and the telephone fi3.4, . . . , 24 will be explained to the dog.

First, in the case of a call from the door phone 2, when the call signal from the door phone 2 enters HB C1 through the door phone inter 7 2s 106, HBCl is sent to the communication path switch circuit 1.
16 operates the communication current supply circuit 117, and supplies communication current to the telephone @ 13a or 13a or 13b through the relay contact ``, 14'', and transmits the doorbell information to each telephone 3.
,4. . . , 24 or the independent telephone Agebuta 7 by means of the transmission signal S, and the signal sound circuits 305, 405, . . .
401-..., the input beaker 318,
418...Sounds a small chime and flashes the display lamp of the doorbell display to indicate that there is a call from the doorbell 2.

When the /% end set of one of the telephones is picked up by this call, the telephone #! 11. A connection is established through a or r3b and a call is established, and at the same time the control data that switches the blinking of the indicator lamp above to lighting is H.
Each phone call costs $13.4 from BCl.

24, and the respective display lamps are lit.

When calling the doorphone 2 from the following two telephones 3.4, 24, or 6, pick up the handset of the telephone and operate the doorphone button provided on the telephone or Agebuta 7. Under the control of the HBCI, A connection is established with the doorbell and calls can be made.

In addition, if multiple door phones 2 are installed and there is a call from another door phone while a call is being made to one door phone, by pressing the door phone button, the phone can issue a connection request to the other door phone to HBCI. Vero. Furthermore, if there is a doorbell call and an incoming call from outside #I at the same time, the HB C1 gives priority to the incoming call from outside #a, and connects after outside #i according to the telephone set with the handset raised. Furthermore, if the doorbell calls during an outside line call, by operating the doorbell hook, you can request connection to the phone 2 and request that the outside line be put on hold.I]B
By replying to C1, a call can be made to door phone 2 and an outside line can be placed on hold. This request to release the outside call hold can be made by operating the doorphone button again. Furthermore, if a doorphone call is received during an extension call, a connection request to the doorphone 2 can be made by operating the doorphone button. In this case, the extension call is stopped. Also, telephones 3 and 4. ....

24, if you press the button dial corresponding to the doorphone number set on doorphone 2, the doorphone number data will be sent to the HBCI along with the connection request.
, and the corresponding doorbell 2 can be called. If this dial is not operated, the HBCl selects and connects the door phone 2 that was last used. Note that you can restrict the chime sound by operating the call rejection button.

Next, the telephones 113-4 +..., 24 and unit 9 of this system are each equipped with microphones 317, 417... that collect the sounds of a certain room, so that a so-called room monitor can be performed. It has become.

In other words, the telephone in the room you want to monitor, for example, the child telephone 4.
When the handset is raised and the monitor setting button is pressed, an interrupt request signal INT is sent from the corresponding slave phone 1s14+ to HBCl. When the handset is returned and the interrupt request is processed, the monitor mode data is transferred from the slave phone R4 to the HB.
A reply signal RT is sent back to Cl, and the HBCI that has received this reply signal RT transmits data indicating that it has been received to the slave phone 41 using the transmission signal S, and displays the monitor display of the slave phone a41. The display lamp blinks under the control of the microcomputer 401, and the child phone 19t
41 is set to the monitored side.

Next, when the monitor setting button is pressed on the monitor side phone, for example, the base phone 3, data is exchanged with the HBCI in the same way as the above settings, and the display lamp of the base phone 3 is turned on. After lighting up, each phone 41, 3

Connect to telephone extension era or l, b through s+swr++s. The amplifier 417 of the telephone tf141 on the monitored side is connected to the microcomputer 401.
The audio signal collected from the microphone 417 is transferred to the amplifier 417, the mixing circuit 414, and the coupling transformer 413.
Telephone @ 13 a or 1. b to the main phone 3 on the monitor side, and the ml is reproduced by the speaker 318 through the coupling transformer 313, mixing circuit 314, and amplifier 316 in the filler 3 for monitoring.

If you want to end this monitor, use the main phone R3 on the monitor side.
All you have to do is operate the room monitor button, and after receiving the interrupt request number INT caused by the operation of this room monitor button and processing the interrupt, receive the monitor end request data from the parent 'iJ1 episode 3. The HBCl transmits the control data for terminating the monitor connection to the telephones 3 or 4 on the monitored side and the monitor side. and terminate the monitor connection.

In addition, for the above-mentioned monitoring operation, priority is given to external calls and internal calls, and when these calls occur, the room monitor is automatically suspended, and the monitor is restarted after the call ends.
B C1 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 ■S in the monitoring mode using normal polling.
Various sensors 11 are connected to each other by accessing them.
The monitoring data is sent back as reply signals R and T, and the monitoring data is transmitted to the parent alarm unit 8 using a control mode transmission signal S. Here, if an abnormality is detected in the sensor 11, the parent alarm unit 8 activates the voice synthesis circuit 8.
09 and the signal tone circuit 805 are connected to the microcomputer 80.
1, generates an alarm sound signal and a message signal according to the detection sensor, makes them sound from the speaker 815, simultaneously sends an interrupt request signal tNTt-HBC1, and after processing the interrupt, transfers the abnormal alarm. The parent alarm unit 8 returns the alarm data to HBCl using a long AC/Ritz reply signal RT. The i-+B C1 which received these reply signals R and T is each telephone fi3.4 having a speaker for alarm.

. a or extension phone 1. b, and further transmits control data for connecting the alarm sound signal and message signal to the telephone extensions ff13a, e, and b to the parent alarm unit 8 using the transmission signal ■S, and transmits the alarm sound signal and the message signal. Each telephone 3,
4. .

In addition, when the notification set button is set, B C1 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, using the Guyara 111. When the notification is started, a notification lamp is turned on in the parent alarm unit 8.

When the response detection circuit 808 detects that the handset of a telephone outside the system is picked up and the polarity of the line is reversed, a notification message signal is output under the control of the microcomputer 801 of the parent alarm unit 8, and the message is is reported, and the display lamp changes from blinking to lighting. This message is simultaneously emitted from the speakers 318, 418, 708 of each telephone 3, 4, .

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 does not respond, the notification will be repeated a predetermined number of times by redialing again.

*The HB C1 performs control operations so that the automatic notification of an octopus will not be interrupted and stopped even if the sensor 11 no longer detects the call.

If the handset of telephone 3, 41..., 24 or 6 is picked up during this notification and the outside line connection button is pressed, H
Automatic reporting was suspended under the control of the BCI.

A line connection is made so that the call with the other party is given priority, and when the call ends, the interrupted reporting operation is resumed.In conjunction with the above-mentioned alarm issuing operation, the line is connected to the sensor connection unit (13). A return signal RT is sent from the parent alarm unit 8 to control data for ringing the emergency bell 27.
13! :M consecutive emergency bells 27 are sounded under the control of the arithmetic processing circuit 131.

Furthermore, the parent alarm unit 8 requests the HBCI to connect the call #i16 of the door phone 2, and the speaker of the door phone 2 issues an alarm sound and a message until there is a response to the automatic report.

By the way, the above operation has been explained regarding the detection operation of the sensor 11, but the sensor connection unit 13 or the telephone ffi 3
y 4 +..., 24 or when the emergency button switch provided on the standalone telephone Agebuta 7 is operated, an interrupt request signal INT is output, and after processing the interrupt request, the emergency button switch is sent to the parent alarm unit 8. The operation data is transmitted from the HBCI by the transmission signal S, 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. Also, when the emergency button switch of the main alarm unit 8 is operated, the main alarm unit 8 sends i(B C
1, the transfer data is returned by interruption, and thereafter the same processing as in the case of the detection operation of the sensor 11 described above 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 malfunction of the sensor 11, the switch SW sets automatic notification only when the emergency button switch is operated even when the notification set button is not set.
1 is provided in the peeping alarm unit 8, and when the parent alarm unit 8 returns the transfer data to the HBCI, it returns the setting data of this switch SW1 together with the automatic notification setting data, and determines whether to perform automatic notification. HB for negative decision
This is done by CI. Therefore switch S
If W+ is turned on, an automatic report will always be made when the emergency button switch is activated.

By the way, the detection operation of the crime prevention sensor 11C among the sensors 11 is effective only when the crime prevention alarm is set.
This sector reset of the security sensor 11C can be carried out using the telephone line system control described later, or by using the switch SW2 provided on the parent alarm unit 8 or the child alarm unit (8a) that does not have the FI function for automatic reporting of the parent alarm unit 8, or the sensor connection unit. This can be done by handling the .

Operation data of the switch SW2 of the child alarm unit) 8a or the sensor connection unit 13 is requested for an interrupt at the time of operation, and after the interrupt is processed, it is transmitted to the HBCl, and then sent to the H
The parent alarm unit 8 is activated by the transmission signal ■S from the BCI.
This transmission signal ■S will be transmitted to and registered from the rear view alarm unit 8? ! The display data is returned to the HBCI in response to the FIQ-inclusive request, and the warning set and reset display lamps of the sensor connection unit 13 and child alarm unit 8a are turned on in accordance with the control data from the HBCI. Of course, the switch SW of the parent alarm unit 8
During the second operation, no operation data is transmitted to the HBCI.

Triggering 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 although the main alarm unit 8 is automatically notified, A switch SW is provided to regulate the information.

When this switch SW3 is turned on, the parent alarm unit 8 transmits H data to stop alarm issuing within the system.
Send it to the BCl side, 1 each! Story 1g! 3.4. .

24 and standalone phone adapter 7 speakers 318°41
8 and 708 are restricted.

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 carried out through telephone outside line La, 1. This cannot be done if b is occupied by a call from outside the system, so in this system first call #ilQ outside the free phone,
, a or Q, , b are determined by the HBCI CPU 101 depending on whether or not the incoming call detection circuit 108 detects an incoming call, and 'g! If there is an external telephone line available, the above-mentioned automatic notification is performed using that external telephone line. In addition, if there is no free outside line, a message is sent to a commercial outside line with a predetermined priority order, and when the message notification is completed, the line is forcibly opened and calls to the other party are stopped. The above-mentioned automatic call is made using the external telephone line. In this way, even if an external telephone line that is intentionally connected is put into a ringing state by a telephone outside the system and the line is blocked, automatic alarms can be issued without fail, and the reliability of the system can be improved. It can be done.

In addition, when the above-mentioned sensor 11 or the emergency button switch is activated, the telephone fi3.4 is in a state where the handset is picked up.
,..., 24 or the speakers 318, 418, 708 of the independent telephone Agebuta 7 are connected to the network circuit 312, 412 side, or are disconnected from the telephone #i13 a, l, b. , the alarm sound and 1 message from the parent alarm unit 8 are not notified, but in the HBCI, the signal sound circuits 305 and 40 provided for those in the talking state
5.705 is sent, and a sound signal from the signal sound circuit 305.405.705 is used to generate 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 from the door phone 2, and displays an image on the monitor television 23. When there is a call signal from the main wireless phone 2, the HBCI transmits control data to the camera switching unit 22 using the transmission signal S, turns on the corresponding monitor television camera 21 connected to the camera switching unit 22, At the same time, the control data for the start of operation m4 is sent to the monitor 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 2 through the coaxial cable 15.
The video is sent to the telephones 3, 4, .
. . . If the interlocking relationship is set for 24 and 6, the HBCI first sends a transmission signal S to operate all monitor televisions 23, and then the hand 7t is taken.
The operation of the monitor television 23 that does not respond to the IL call is stopped, the video is displayed only on the monitor television 23 corresponding to the telephone that is talking to the doorbell 2, and when the call ends, the operation of the monitor television camera 21 and the operation of the monitor television 23 are stopped. Transmission signal ■S to stop the camera switching i unit 22
The data is transmitted to the TV 23 every 1 to 2 days.

When displaying an image on the monitor television 23 without interlocking with the doorbell 2, it is best to operate a monitor switch provided on the monitor television 23. In this case, the monitor television 23 returns an interrupt request signal INT to the HBCI, After the interrupt request processing is completed, the HBCI transmits control data for operating the corresponding monitor television camera 21 to the camera switching unit 22 using a transmission signal VS,
The monitor television camera 21 is operated. After the monitoring is finished, if the monitor switch is operated again, the same processing as during 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 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
BCl transmits control data for sequentially switching each monitor television camera 21 to the camera switching unit 22 as a signal VS.
The video signals from each monitor television camera 21 are sequentially transmitted to the coaxial cable 26. In conjunction with the operation of each monitor television camera 21, a transmission signal vS 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.

Next, control of equipment load R by telephone line system control and one multiplex transmission system will be explained.

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
The CI 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.

The control state of the predetermined equipment load R among the equipment loads R can be monitored in the telephone line system control monitor unit 9. In other words, when the monitor command button of the telephone line M control monitor unit 9 is operated, the 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 returned to the HBCI as a reply signal RT, and this reply signal R
Based on T, the display data is transmitted from the HBCI to the telephone line system control monitor 9 by the transmission signal The operating state of R can be transmitted to the speaker 912 by a voice message. 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.

Further, the telephone line system control monitor unit 9 is provided with an operation button for controlling a specific equipment load R or the electric lock 18, and setting and resetting security alarms, and when this operation button is pressed, the above-mentioned remote control switch 16 is activated. The equipment load R or the electric lock 18 is controlled in the same manner as in the case of activation, 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 HBCI transmits control data to turn on the display lamps provided in the corresponding remote control switches 16, etc., and the display data is transmitted to the telephone M system control monitor unit 9. The message is then transmitted to and monitored by voice message.

By the way, the telephone line system control monitor unit 9 is set to be able to control the equipment load R and the electric lock 18, set and reset security alarms, and monitor the status of telephones outside the system. Setting can be performed using a teleconference set switch SW0 provided in the unit 9. That is, when the telephone set switch SWo is set, the display lamp for displaying the setting is lit by exchanging data with the HBC 1, and along with this lighting, the telephone port #it system control is set.

Therefore, when there is a call from a button telephone from outside the system, the HBCI will call outside the telephone @ 1, a or!
1b to telephone extension fla 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 a control code sent from outside the system is received by the DTMF receiver circuit 905 and sent back to HBCl in the same way as the password, and HBCI sends 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 code. At this time, the speech synthesis circuit 907
voice message signal in the telephone #il*a or t,
Outside telephone connected through b @ 1 la or 1. b, and the control status can be monitored on the connected telephone. 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 by a control hood from a telephone set outside the system, but in this system, the telephone line system control monitor unit 9 includes a test switch SW,
When this test switch SW is operated, an interrupt request signal INT is sent from the unit 9 to the HBC.
After processing the interrupt, the test request data will be sent back to the HB that received the test request data.
Cl transmits connection control data using a transmission signal S so as to connect each telephone set 3, 41, . conduct. After that, when a predetermined control code is input from the telephone with the handset raised by operating the button dial, data is transmitted between the telephone and the telephone line system control monitor unit 9 via the HBC 1, and data is transmitted outside the system. It will be possible to monitor and control the device in the same way as a telephone. 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. Furthermore, HB
A transmission signal Vs is transmitted from the CI to the electric control unit 14, and the electric lock control unit 14 that receives this transmission signal S returns data indicating that it has entered an alarm state, key status data, and status display data to the HBC 1. S, HB
C1 transmits each data to the operating 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, and the HBCI
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 HBCl transmits this data to the operation switch 19 (IIII) in the same way as when automatically locking, and unlocks it. Furthermore, unlocking and locking can also be performed via telephone line system control, and the control data at this time is transmitted from HBCl to the electric lock control unit 14 based on the received control code from the telephone screen mIA control monitor unit 9. be done.

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 HB C1 in the same way as when the sensor 11 detects the operation. Of course, an alarm can be issued.

Furthermore, a switch 25 is connected to the electric lock control unit 14, and when the same number as the preset password is input by the secret switch 25, the microcomputer 1411 of the electric lock control unit 14 It is now possible to unlock or lock the door by determining this match. Of course, the password can be set using the keyboard of the secret switch 25 in the built-in RAM of the microcomputer 1411! :Can be set.

Now, in this system, the pin number for telephone line control, 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 set on the telephone 3.
,4. ..., 24 pusher button dials and 7 others
Settings can be made using the operation buttons for the 77-axis dial, and the operation is basically the same as the speed dial setting method described above, with the only difference being the operation buttons used for the 77-axis dial.

By the way, such registered data is stored in RAM1 of HB C1.
03, the registration data related to the automatic notification is stored in the MRAM of the micro combiator 801 of the parent alarm unit 8, and the password for telephone #i system control is stored in the microcomputer 901 of the telephone line system control monitor 9.
It is now registered in @RAM.

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.

That is, the unit 8 or 9 checks the registered data in its own i1RAM at regular intervals as shown in FIG. 15, and if the registered data has not been erased, it proceeds to normal processing. If the registered data has been erased, an interrupt request is made to the HBCl to request the transfer of the corresponding registered data, and at the same time a built-in timer is set. If there is a transfer, the registered data is registered in the built-in RAM of each unit 8 or 9.

If registration data is not transferred even 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 display lamps provided in each unit 8 and 9 blink, and the unit enters a registration waiting state.

The user who sees this blinking can register the registered data erased by pressing the operation button 24 on the telephone@3.4bi, using the above-mentioned speed dial registration capacity, and by this registration, the HBCI 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
AM is registered, and the blinking of the above-mentioned display lamp is stopped.
