Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an answering machine, and more particularly to an answering machine that can be combined with a security system and allow the status of the security system to be monitored from outside by telephone.

[Conventional technology]

For example, if a family member goes out and is concerned about whether or not the security system is set to the specified security mode, he or she may check the security system's security mode over the phone from outside without third parties knowing, or set the security system to the specified security mode. You may want to confirm that there are no abnormalities in the status.

Home security systems are already known as systems that meet this purpose (for example, Japanese Patent Application Laid-Open No. 1983-1999).
139300). Such a home security system is a conventional security system with telephone answering means added. For example, when an inquiry is made from a pulse dial telephone, it is determined whether the voice is from a pre-registered speaker or not, and the security situation is responded to only to the matched speaker.

On the other hand, in the case of a multi-frequency dial (push-button) telephone, a multi-frequency signal that serves as a code is determined in advance and the response is made only when that signal is received, and in the case of a digital telephone, it responds to keyboard input on the transmitter side. I try to do that.

[Problem that the invention seeks to solve]

However, the above-mentioned system has to be configured according to the type of telephone, making the system complicated. Particularly in the case of ordinary pulse dial telephones, there is a problem in that the registration of the speaker's voice and the means for recognizing it are quite complicated.
In addition, problems such as restrictions on acceptors regarding speaker voice registration and recognition errors are expected. Furthermore, there is a problem in that adding such functions to a security system increases the cost considerably.

[Means to solve the problem]

In the present invention, means is connected to an alarm device that sends an alarm signal in response to a signal from a detector, and a means for recording the alarm signal, and a beep tone corresponding to the presence or absence of an alarm or the type of alarm in response to a call. There is provided an answering machine, characterized in that the telephone answering machine is equipped with a voice response means for outputting a voice including the alarm, and the alarm recording means and the voice response means are operated in an answer recording mode.

The present invention also provides an answering machine connected to an alarm device that sends out an alarm signal in response to a signal from a detector, the answering machine being activated in response to a predetermined security mode set by the alarm device. An answering machine is provided, which is characterized in that:

[For production]

That is, an answering machine and an alarm device are combined, and a warning signal is stored in a recording means within the answering machine. On the other hand, a certain person makes a call from the outside and, in a predetermined mode of the answering machine, outputs a voice that can be recognized only by the specific caller, depending on the presence or absence of a warning signal and its type.

Moreover, the above-mentioned action can be performed in conjunction with a predetermined mode of the alarm device.

In addition, in the above-mentioned answering machine, the recording means records the fact that a call has been made, and the voice response means has a voice pattern depending on the presence or absence of a call, so that when a family member calls the house while the house is not home, , outputs a predetermined voice pattern indicating whether or not there was a call from a third party before that.

〔Example〕

Embodiments of the invention will be described below with reference to the accompanying drawings.

FIGS. 1A and 1B show configuration diagrams of an answering machine system as an embodiment of the present invention. The system is the first
As shown in Figure (A), an answering machine 1, a sensor 2,
An alarm device 3, a mode setting device 4, a main telephone 5, a signal transmitter 7, a transmission line 6, and a monitoring device 8 are connected as shown. A detailed circuit diagram of the telephone answering machine 1 and its connection with the telephone 5 are shown in FIG. 1(B), and the details will be described later.

The set mode signal M operated from the mode controller 4
1 to M3 and the alarm signal ALL detected by sensor 2
, AL2 is input, and the signal transmitter 7 sends it to the remotely placed monitoring device 8 via the transmission line 6.
This is similar to the case with conventional security systems.

The mode controller 4 includes a "set" push button 401 for setting to "warning mode (Ml) J" and a "cancellation" push button 402 for setting to "warning cancellation mode (M2) J".
and a "tour" push button 403 for setting the "tour mode (M3) J", these push buttons are connected to the multi-by-breaks 405 to 407, and the signals S 41 "" S 43 according to the push buttons are connected. Either one is applied to the alarm device 3.

The alarm device 3 includes a condition determination circuit 300 that adds conditions to the operation trigger signals S41 to S4j, a mode setting circuit 310, and a mode storage circuit 320.

The condition determination circuit 300 includes Nant gates 301, 303,
304 and OR gates 302 and 305 are connected as shown. Further, the mode storage circuit 320 is connected to launch circuits, that is, flip-flops 321 to 323 as shown. The operation of these circuits is as follows.

When the "setting" button 401 is pressed and the signal S41 is applied, the previous state is "warning release mode (M2)" (
Qz = 1) r cyclic mode (M3) J(Q'!
“1), it is assumed that the mode setting circuit 310 is valid.
is applied to The mode setting circuit 310 takes into account other conditions, that is, all sensors are set to the alert state, and
When it is determined that the warning mode (Ml) can be set as J, the mode setting signal MS is sent to the flip-flop 32.
1 to the cent terminal (S) of the flip-flop 32.
1 cent. Since Q1=1 due to the setting of the flip-flop "321", the other flip-flops 322 and 323 are loaded. As a result, the "warning mode" is set and stored in the mode storage circuit 320. This mode signal is applied to the answering machine 1, the abnormality detection circuit 330, and the signal transmitter 7. The same applies to other signals. That is, "release mode (M2)" is set when "warning mode (Ml)J" is set as the previous state (Ql = 1).
) J is sent if the previous state is "warning mode" (Q, = 1) or "warning release mode J (Q, -1)."

In addition, the setting to the above-mentioned "warning mode"
It is possible to cause the operation to be performed only when the signal from -0, that is, there is no abnormality.

The alarm device 3 has an abnormality detection circuit 330.

For example, when there is an intrusion detection signal from the intrusion sensor 201, the abnormality detection circuit 331 detects intrusion, and if intrusion is detected, outputs an "intrusion" signal. However, this “
"Intrusion" signal is AND gate 333, alert mode signal Q,
Since the intercock is on, it is in alert mode (
Ml) is output as a valid intrusion alarm signal AL+. Fire sensor 201 or gas leak sensor
(not shown) are similarly detected by the abnormality detection circuit 332, and a fire alarm signal ALz is output.

These alarm signals A are sent from the alarm device 3 to the answering machine 1.
A reset signal R3 obtained by ORing L+, ALz, mode signals M1, M3, M2, and M3 with an OR gate 340.
T is applied. The answering machine 1 will be described with reference to FIG. 1(B). The answering machine 1 includes a disconnector 11
The telephone 5 is connected to the subscriber lines L+ and Lz together with the telephone 5, and is cut off from the subscriber lines LiL+ and Lz in a normal mode in which only the telephone 5 is used. The state of the switches in the illustrated disconnector 11 is such that only the telephone 5 is connected to the subscriber lines L-+ and Lz. Therefore, when operating the telephone answering machine 1, the switch in the disconnector 11 is switched in the opposite state to that shown.

The answering machine 1 is composed of the following components. The above-mentioned disconnector 11, an incoming signal detector 12 consisting of a pair of photocouplers connected in antiparallel to detect whether or not there is a call from a caller, that is, an incoming signal, the other party and the main telephone. 5 are connected by subscriber lines L+ and Lx, and a line monitoring circuit 13 comprising a pair of photocouplers connected in antiparallel to detect whether or not a call is in progress, and an isolation transformer 1

That is, in the present invention, in response to the "warning mode" signal from the alarm device 3, to enable the answering machine in the "answering machine recording" mode and to store the alarm signal in RAM 254 within the answering machine.

Furthermore, as will be described later, these results can be heard from outside via telephone.

The CPo 28 receives an incoming signal S12 and a line monitoring signal S1 from the above-mentioned incoming signal detector 12 and line monitoring circuit 13.
3 is done manually. These signals S12°513 are outputs of phototransistors, and generally have a burst waveform. Therefore, these signals can be sent directly to the CPU.
28 and the incoming call and line monitoring may be performed within the CPU, or the incoming call signal SL2 and the line monitoring signal 513 may be inputted as logic signals processed by providing a processing circuit in the previous stage.

The CPU 28 further includes an off-hook signal S1 for determining whether the telephone 5 is on-hook (telephone not in use) or on-hook (telephone in use).
4 is done manually.

The operation of the answering machine 1 will be described below.

The answering machine 1 is 1. In addition to the "Voice recording" mode described below, it can operate in various modes such as "Call recording" mode, "Prank prevention J mode,""Playback" mode, and "Rewind" mode, but only the directly related ones will be described here. For other modes, please refer to "Answering machine" (filed on July 31, 1980) filed by the present application.

First, the "absence recording" mode will be described with reference to the flowchart of FIG.

Normally, when a family member is away from home, the home is left unattended, so when the "absence recording" button 421 of the mode setting section 42 is pressed and the signal is received by the CPU 28, the absent recording mode is entered (step 5100). On the other hand, if a security system and an answering machine, which is the object of the present invention, coexist, when you are away from home, press the "settings" button 401 on the remote controller 4 to set the alarm device 3 to alert mode. Therefore, in such a case, the absence recording mode can be set without pressing the above-mentioned "absence recording" button 421.

In this state, there is a call from the other party and the incoming signal is 5.
12 is generated (S401).

When the incoming signal S12 is input to the CPU 28, the CPo
(5102,
5103).

After a certain period of time has elapsed, the relay (KA) 36 is energized to close the line (5104). Then CPU B8 sends signal S
1 and closes the analog switch 15 (510
5).

This is to enable the output from the voice synthesis output section 29 to be sent to the other party's telephone. On the other hand, the CPU 28 receives the signal S5
is sent to close the path of terminal A3 of analog switch 17 (S106). After a certain period of time, for example 2 seconds, after energizing the relay (K-A) 36, the voice synthesis output section 29 is activated (S107). The voice synthesis output unit stores predetermined voice content in a ROM, which will be described in detail later, in order to send it to the other party as an answering machine, and the CPo 28 is a ROM in which the voice content is stored. Specify the address of the speech synthesis output unit 29
to drive. This allows the above audio to be filtered through the low-pass filter 3.
0, the analog switch 15, the subscriber line, and the LX. On the other hand, the same contents are terminal A3 of analog switch 17, OR gate 25, volume 26,
The signal is output from the speaker 27 via the amplifier 22. However, since there are no family members present in the normal absentee recording mode, the volume 26 can be turned off so that nothing is output from the speaker 27.

When the voice output is finished, the other party's requirements can be recorded on the cassette recorder 37. i.e. relay (KB)
35 to operate the erasing head (ERS-H) and the recording head (1?EC-H) so that recording can be performed while erasing the previous content (S10B). Also, the relay (K-
C) Energize 34 to enable the mechanical drive to rotate forward (S109). Furthermore, the signal S4 is output to close the path of the terminal A2 of the analog switch 17 so that the other party's requirements can be heard through the speaker 27 (S
LIO). As mentioned above, the speaker can be turned off.

Next, when the mechanical drive 371 of the cassette recorder 37 is driven, the mechanical drive rotates forward and audio recording is performed (Sill, 5112). During recording, the recording level is appropriately determined by an automatic gain control circuit (not shown), and recording is performed on the tape at an appropriate level. The rotational speed of the capstan motor of the cassette recorder is determined by the CPU 28, and tape position information is displayed on the segment display section 33 as the recording time elapses. This audio recording continues as long as the line monitoring signal S13 continues (511
3). However, recording can be stopped when the recording tape ends or after a certain period of time has elapsed in the case of a long conversation.

In addition, in the present invention, when a call is made from outside, that fact is recorded in the RAM 254 (Sllll
a).

Regarding this call, it is sufficient to detect either when the voice synthesis output circuit 29 operates or when the cassette recorder 37 operates and store it in the IIAM 254.

When the above recording stop condition occurs, the CPU 28 stops the mechanical drive 371 (S114).

The answering machine recording mode ends when the "answering machine recording" button 421 is pressed again and the answering machine recording request signal is turned off, or when the "warning mode" is canceled, or when the telephone 5 is taken off-hook. Otherwise, wait until the next incoming signal arrives (5115.5116).

If one or more of the alarm devices is operating in the "absence recording" mode, the alarm signal AL1. When AL2 is output,
Contents corresponding to the type are stored in the RAM 54.

That is, in the RAM 54, when there is an alarm signal from an external telephone or the alarm device 3 during the "absence recording" mode, the contents are stored in the order of occurrence.

If you don't have any of these, what about RA? 'l 54 remains cleared.

Next, details of the speech synthesis output in step 5107 in FIG. 2 will be described below with reference to the flowchart in FIG. 3.

The ROM in the speech synthesis output unit 29 stores data corresponding to the speech as shown in Table 1.

Below is the margin No. 1 Table First, select the 1st to 3rd output words in order and the speech synthesis output unit 29
From there, the following sounds corresponding to these are filtered through a low-pass filter 3.
0, sent to the calling party via the switch 15 (S50
0-5502).

[These are XX.

I'm away at the moment. ” Next, the contents of RAM 54 are searched and the warning signal A series 1 is detected.
゜Check whether Al1 or a call has already been made,
If applicable, the corresponding beep tones are listed in Table 1.
Select from Kan 8 to 10 and output as above (S503
~5508). That is, if there is a warning signal ALL: "Beep beep" If there is a warning signal AL2: "Beep beep" If there is a call = "Beep beep" A beep tone is output to the caller. On the other hand, if none of the above is present, a normal beep tone, ie, "beef" is output (S509).

Next, the fourth to sixth output words are selected and the following is output (S
510-5512).

[If you hear the sound, please speak for 30 seconds. ” Furthermore, the selections in steps 5503 to 5509 are output again (S!513).

After this, the process continues to step 5108 in FIG. 2, and the recording operation begins.

Here, if the caller is a member of the household or a similar person, the meaning of the beep tone is known in advance. Therefore, if such a person makes a call from the outside to a home where no one is present, he/she will hear the voice output as described above from the receiver (thereby, since the answering machine 1 is in the answer recording mode, the alarm will be sent first). It can be confirmed that the device 3 is set to the "alarm mode" because the alarm mode signal causes the answering machine 1 to operate in the "answer recording" mode as described above.

Next, even if you are outside, you can know the details of the alert status at home or whether or not someone other than yourself received a call while you were away. Therefore, if an abnormal signal is generated,
The monitoring device 8 makes it possible to make detailed arrangements or give instructions to the Iiff center.

In the above embodiment, beep tones are output in the priority order of ^Ll, AL2, and calling, but this order can be changed freely, and all events can also be output. good.

Various patterns can be set for beep tones, and the association between beep tone patterns and events can be easily changed depending on the system. Therefore, even if the beep tones have the same pattern, they indicate different contents depending on the user, and confidentiality is maintained.

Further, in the above-described embodiment, either the alarm mode (Ml) from the alarm device 3 or the "absence recording" button 421 of the mode setting section 42 causes the device to operate in the "absence recording" mode as described above.

Therefore, it may not be possible to identify that it is one of the above cases, and the alarm device 3 may not be in the alert mode even though the "absence recording" button has been pressed. Therefore, as shown in Figure 1 (B), ORGATE 5
The output of Frisopflosop 50 is directly connected to CP0 without going through CP0.
28, the CPU 28 records this in the RAM 254 when there is an input to the flip-flop 50, and clears the above record in the RAM 254 when the flip-flop 50 is reset.
In response to the input of the flip-flop 50, "absence recording" is performed.
If the button 421 is off, the mode will be set to "Voice recording j mode."On the other hand, if there is an inquiry from outside, the message shown in Table 1 will be displayed instead of the normal response beep tone (Tables 1 and 7).

Output an eleventh beep tone. That is, the beep tone when the "absence recording" mode is set by the "absence recording" button is "ping", and when the alarm mode signal is used, it is "peets beep", which can be identified.

However, if it is just this, it is not possible to tell whether there is a v-report or not, so after the first beep tone, that is, "This is XX. I am not at home at the moment.", the above "ping" or "pifu piso" is output. , the second beep tone can be made into an audio output corresponding to an event as shown in the flowchart of FIG.

The embodiment shown in FIG. 1(B) shows an example realized using the CPo 28, but the above-mentioned processing is sequential control and is not very complicated, and can also be realized by a relay sequence etc. By the applicant on July 3, 1982
(See "Answering machine" filed on the 1st). It goes without saying that the security system also applies to so-called local security systems that are not coupled to the monitoring device 8 via the transmission line 6.

Note that the above-mentioned functions can be provided as appropriate.

〔Effect of the invention〕

As described above, according to the present invention, the above-mentioned circuit is added to the functions of an answering machine, and the operating mode status and alarm status of the security system can be monitored relatively easily and with confidentiality maintained! 1! can be approved.

Furthermore, the answering machine can be set to the "answering machine recording" mode simply by setting the mode controller on the alarm device side.

Further, according to the present invention, it is possible to know from the outside whether or not there is a call from a third party other than the user himself while the "answer recording" mode is activated.
