DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A notification device used in this embodiment
The device 1 is configured as shown in FIG.
Alarm device 2 is connected in the same way as
Emergency switch 3 is connected. Emergency switch 3 is a terminal
t_FifteenAnd the alarm device 2 is connected to the terminal t. ₁₆Connected to.

The alarm device 2 is connected to various sensors and switches for disaster prevention or crime prevention. As shown in FIG. 2, the alarm device 2 has an indicator light 21 for indicating the operating state of the various sensors and switches. A push button switch 22 for emergency notification is provided. Further, an intercom slave unit for communication between the rooms can be connected to the alarm device 2, and a handset 23 is provided for communicating with the interphone slave unit. The alarm device 2 monitors outputs of various connected sensors and switches, and is configured to transmit a notification signal to the notification device 1 when an abnormality is detected. Also, when the push button switch 22 is pressed, a notification signal is sent to the notification device 1.

The notification device 1 transmits a notification signal from the alarm device 2 and a notification signal from the emergency switch 3 to the abnormality information detection circuit 1.
2 and gives the contents of the notification signal to a control circuit 11 comprising a microcomputer. That is, the abnormality information detection circuit 12 functions as information detection means. In the control circuit 11, a telephone number of a notification destination is set in advance for each content of the notification signal. The control circuit 11 receives the contents of the message signal from the abnormality information detection circuit 12, disconnect the telephone 5 from the PSTN 4 by switching the switching contact r _11, r ₁₂ consisting of the relay contact that is connected to a public network 4. Common contact of one of the switching contacts r ₁₁ is connected to the terminal t ₁₁ via the line state detection circuit 14 is a line status detecting means, the common contact of the other switching contact r ₁₂ is connected to a terminal t _12, the terminals t
₁₁ and t ₁₂ are connected to the public network 4. The telephone 5 is connected to one of the switching contacts r ₁₁ and r ₁₂ via terminals t ₁₃ and t ₁₄ . Here, the contact for connecting the telephone 5 may be a normally closed contact. Therefore, when the telephone 5 is connected to the public network 4 via the switching contacts r ₁₁ and r ₁₂ , a telephone call with the telephone 5 becomes possible.

[0015] Between the other contact of the switching contacts r _11, r ₁₂ D
P signal contact r ₂ of the (dial pulse signal) for generating is inserted, a series circuit of the secondary winding and the contact r ₃ of the transformer T is connected in parallel to the contact r _2. Therefore, the telephone 5 is disconnected from the public network 4 by the switching contacts r ₁₁ and r ₁₂ ,
And in a state of turning off the contact point r _3, it is possible when opening and closing the contact r ₂ sends a DP signal to a public network 4. Opening and closing of the contacts r ₂ is controlled by the dial transmission circuit 13, comprising a telephone number of the notification destination to be sent to the public network 4 by DP signal.

On the other hand, a communication control circuit 15 is connected to the primary winding of the transformer T. The call control circuit 15 selects which of the dial sending circuit 13, the call circuit 16 and the voice synthesizing circuit 17 is connected to the transformer T. Dial transmission circuit 13, a public network a DTMF signal when has a function of outputting a DTMF signal (push button dial signal) over a traffic control circuit 15, the contact r ₃ contacts r ₂ is off is turned on 4 can be sent.
The communication circuit 16 enables so-called hands-free communication without using a handset, and includes a microphone and a speaker.

The voice synthesizing circuit 17 is a circuit in which a message corresponding to the notification signal is registered in advance.
When an instruction corresponding to the notification signal is received by 1, a message is transmitted by a synthetic voice. For example, when a fire is detected by a fire detector connected to the alarm device 2, a message such as "a fire has occurred" is transmitted as a synthesized voice. Thus, the control circuit 11
The call control circuit 15 and the voice synthesizing circuit 17 constitute a notification notifying unit.

In short, the DTMF signal is transmitted to the public network 4 by selectively connecting _one of the dial transmission circuit 13, the communication circuit 16 and the voice synthesizing circuit 17 to the transformer T1 by the communication control circuit 15. The user can make a call to the notification destination, or send a message using synthesized voice to the notification destination. In the present embodiment, both the DTMF signal and the DP signal can be transmitted to the public network 4, and the control circuit 11 and the dial transmission circuit 13
, The contacts r ₂ and r ₃ , the communication control circuit 15 and the transformer T constitute a dial sending means.

In the present embodiment, the notification destination is notified when the notification destination is busy or the notification destination is changed, and the notification destination can be notified. If not, it has a function to notify the user of this. That is, the control circuit 11 is connected to the display unit 18 having the notification destination indicator lamp 18a as notification success / failure notification means for performing visual notification by turning on / off. Further, an operation unit 20 including a switch group is provided as a notification destination setting unit for setting a telephone number of a notification destination. The operation unit 20 is also provided with a cancel button 20a for collectively canceling the notification by the notification success / failure notification means. A plurality of notification destinations can be set, and the notification destination indicator 18
a is provided for each notification destination. In other words, the control circuit 11 determines whether or not the notification destination indicator lamp 18a needs to be turned on / off and the notification of the voice message is necessary based on the output of the line state detection circuit 14 for each notification destination. The display unit 18 is also provided with a notification lamp 18b that blinks while calling a notification destination and performing notification notification.

The control circuit 11 also has a function as a retransmitting means for recalling a report destination for which report notification has not been established after a retransmission interval of a predetermined time after a call of each report destination has made one round. The resending means recalls only the notification destination for which the notification was not established, and the maximum number of retransmission calls can be set by the operation unit 20. In general, if the number of calls is increased, the possibility of establishing notification is increased. However, if the number of calls is increased, external calls cannot be made. Therefore, the number is set to an appropriate number as needed. Further, the control circuit 11 includes a time interval changing unit that changes at least one of the notification interval and the retransmission interval after the notification with the notification destination is established.

Next, the basic operation will be described with reference to FIGS. FIG. 3 shows a case where dialing is performed by a DTMF signal and notification notification is established, and FIG. 4 shows a case where dialing is performed by a DP signal and notification notification is not established. (A) of each of FIG. 3 and FIG.
(B) shows a change in voltage between telephone lines. First, FIG. 3 will be described. When receiving the notification signal from the alarm device 2 or the emergency switch 3, the abnormality notification detection circuit 12 gives a notification signal as shown in FIG.
Then, the voltage of the telephone line changes as shown in FIG. The switching contacts r ₁₁ and r ₁₂ always connect the telephone 5 to the public network 4, but when a notification signal is given to the control circuit 11, the switching contacts r ₁₁ and r 12
By switching ₁₂ , the telephone 5 is disconnected from the public network 4. Subsequently, after the ON for a predetermined time to contact r ₃ as shown in FIG. (B) by the control circuit 11, turns off the contact r _3. Thereafter (when there is a response from the exchange), the control circuit turns on the contact r ₃ , connects the dial transmission circuit 13 to the transformer T via the communication control circuit 15, and transmits a DTMF signal to the public network 4. When the notification destination (the other party) answers within the predetermined time, the telephone becomes available for communication. After that, when the predetermined time elapses or the notification destination finishes speaking, the notification notification to the notification destination ends.

Next, FIG. 4 will be described. Anomaly detection

If the notification destination does not respond within the fixed time,
The call is not established (report notification is not established).

In the present embodiment, since a plurality of notification destinations are set, the operation shown in FIGS. 3 and 4 is repeated for each notification destination. However, for notification destinations for which notification notification was not established, dialing is sequentially performed for each notification destination, and after dialing to each notification destination has completed one round, notification notification is not established after the retransmission interval time has elapsed. Dialing is performed sequentially only for those that have occurred at each reporting interval. In addition, the maximum number of dialings to one notification destination is limited to the number of calls set as retransmission means in control circuit 11. Next, the notification interval to each notification destination will be described with reference to FIG. Here, in the operation example shown in the figure, three notification destinations (three notification destinations A, B, and C) are set, and the number of calls to the retransmission unit is set to two (retransmission). Since the number is two, the call is made up to three times), and the notification is established to the notification destination A by the second call.

The control circuit 11 sequentially calls notification destination A, B, notification destination A for each predetermined report interval T ₁ is relatively short time when reporting to C is not satisfied, B, and C, notification When notification of the previous a is established, to change the report interval T ₃ is relatively long in comparison to report interval based on the notification interval T ₁ by a time interval changing means (e.g., about 3 minutes). Thereafter, call notification destination B, sequentially for each notification interval T ₁ to C. Therefore, in the present embodiment, since the report to the notification destination A does not perform the notification to only the notification destination B between Problem interval T ₃ after completion satisfied, respond when the notification destination A had phone folded You can. Furthermore, since notification is Problem interval T ₁ of the case and had been satisfied is set to a relatively short time, notification is because calls quickly following notification destination becomes unsatisfied enables rapid notification informing disaster Etc. can be prevented from becoming large. In the example of FIG. 5, when the notification is established, the time interval changing means increases the notification interval. However, if the notification interval is set shorter than the original notification interval except when the notification is established. Therefore, it is possible to quickly make a call to the notification destination, and it is more likely that a response can be made when a return call is received from the notification destination where the notification has been established.

FIGS. 6 to 8 show other operation examples. Also in these illustrated examples, three notification destinations are set, and the number of calls of the retransmission means is set to two (the number of retransmissions is two).
Calls up to three times). 5A to FIG. 8A, the presence or absence of a notification signal, FIG. 5B is a state of turning on / off the notification lamp 18b, and FIG.
This shows a state where B and C are being called.

In the examples shown in FIGS. 6 to 8, the notification destination A has been notified by the second call. The call is performed in the order of the notification destination A, the notification destination B, and the notification destination C. However, since the notification notification has been established twice in the notification destination A, the call is not performed thereafter. Thus, FIG.
When the notification signal is input as shown in FIG. 3A, the notification lamp 18b starts blinking as shown in FIG. 4B, and the notification destinations A, B, and C are set in advance as shown in FIG. sequentially call for each report interval T ₁ to have. In this example, the report to the notification destination A is established in the second call, the control circuit 11 informs the destination B, retransmission interval retransmission interval from Problem interval T ₀ by the time interval changing means after the call to C change to T ₂ perform the following call. Thereafter, it calls a notification destination C in the usual Problem intervals T _1, sequentially call notification destination B, and C for each notification interval T _1. In this example, after notification to the notification destination A is satisfied, the notification destination B in the normal report interval T _1, C
, The retransmission interval is changed from ₀ to the retransmission interval T
_{Since the number} is changed to ₂ , the notification interval T ₂ is appropriately set according to the number of notification destinations that have been notified by calling the same number of notification destinations A, B, and C in advance. Is also possible, and the possibility of being able to respond when there is a return call from the notification destination A where the notification has been established is increased, so that prompt measures can be taken.

Also, in the example shown in FIG. 7, when a notification signal is inputted as shown in FIG. 7A, the notification lamp 18b starts blinking as shown in FIG. notification destination a, B, sequentially call each Problem interval T ₁ which is preset C as. In this example, the notification to the notification destination A is 2
When satisfied with round eyes call, the control circuit 11 is changed from Problem interval T ₁ the notification interval by a time interval changing means to Problem interval T _2, sequentially performs a notification destination B, C calls per Problem interval T _2. Further, the control circuit 11 is set to a time equal to the original retransmission interval T ₀ even retransmission interval to Problem interval T ₂ the time interval changing means. In this example, after the notification to the notification destination A is established, the notification interval is always the notification interval T ₂
, And the retransmission interval becomes longer than the original retransmission interval T ₀ , so that the possibility of being able to answer a call back from the notification destination A increases. In this example, after the report is established, the report interval and the retransmission interval are longer than the original interval. However, the report interval and the retransmission interval may be shorter than the original interval until the report is established. In this case, the call to the notification destination can be promptly performed, and the possibility of being able to respond when a return call is received from the notification destination where the notification is established increases.

Also, in the example shown in FIG. 8, as shown in FIG.
When a notification signal is input as shown in FIG.
The light 18b starts blinking, and the notification destination as shown in FIG.
A, B, and C are set to a preset report interval T₁Your
And call sequentially. In this example, the notification to the notification destination A is 2
When the call is established at the second call, the control circuit 11
After calling to B and C, the time interval changing means
The retransmission interval T ₀From retransmission interval T_TwoChange to
The notification destination B is called. After that, the report interval T₁
To call the notification destination C, and then the retransmission interval T_TwoInformed
Call B. In this example, the notification to the notification destination A is established.
After the retransmission interval is set to the retransmission interval T_TwoAnd the notification destination
Possibility of being able to answer when there is a call back from A
Higher, and calls to other notification destinations B and C are prompt
Can be done quickly.

As described above, the switching contact r₁₁, R₁₂Is
