Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an emergency notification device using a telephone line.

[Background technology]

In general, an emergency notification device has several preset destinations to notify of the abnormality when an abnormality such as a fire occurs, as shown in FIG. In Figure 1,
1 is a fire sensor, 2 is a gas leak sensor, and 3 is a security sensor. 4 is a terminal device for receiving emergency input from each sensor 1 to 3 and making an emergency report. The output of the terminal device 4 is switched by the exchange 5 and sent to any one of the reporting destinations a ₁ to a _o . When an abnormality occurs, the method of calling the notification destinations a ₁ to a _o to notify the abnormality is to call the notification destinations a ₁ to a _o in sequence, and if there is no response, call each notification destination a again in the order of a ₁ to _{a o} . A common method is to repeat the call a predetermined number _of times until _one or all of them respond. In addition to the automatic dialing function when an emergency input is received as described above, the terminal device 4 also has an absentee home monitoring function, and this absentee home monitoring function is activated when the absentee setting switch 6 is pressed. It's summery. When the home monitoring function is working, the terminal device 4 automatically receives a call when a call is received from outside.
A message to the effect that the user is currently away is sent via the telephone line 7. After that, the caller sends a pin code and a command code for monitoring the house while the user is away using a combination of pushbutton signals, thereby checking the status of various devices 8 such as indoor air conditioners and electric locks, or various sensors. The statuses 1 to 3 are sent as voice messages via the telephone line 7. On the other hand, when the answering switch 6 is not pressed, the automatic call receiving function of the terminal device 4 as described above does not work, and the telephone 9 in the house does not function.
People are starting to receive direct phone calls.

By the way, let's select a so-called pager as the emergency call destination in the conventional example, so that when an abnormality occurs at home, the person first calls the pager and then has the person call home to confirm the nature of the abnormality. However, there was a problem in that if the user forgot to press the set switch 6 when leaving the house, the purpose could not be achieved. In addition, if you do not carry a pager or the like and the situation at home becomes urgent and you call home, but the answering switch 6 is not pressed, the contents of the emergency input will be The problem was that it was not possible to know. However, if you keep pressing the away setting switch 6, even if your family members are at home, the automatic call receiving function will activate and send a message to the effect that you are away, which is still inconvenient.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned points, and even if you forget to press the answering switch when you go out, when an emergency input is received, the answering switch is forcibly switched to the side where the automatic call receiving function is activated and the answering function is automatically activated. The purpose of this invention is to provide an emergency notification device that can monitor a home.

[Disclosure of the invention]

FIG. 2 is a so-called claim correspondence diagram showing the structure described in the claims of the present invention. As shown in the figure, the present invention includes a number storage means 10 for storing the telephone number of a destination to which an emergency call is to be made, and an emergency input detection means for detecting the presence or absence of an emergency input from various sensors 11 placed indoors. 12, an automatic dialing means 13 that calls the telephone number stored in the number storage means 10 when there is a detection output of the emergency input detection means 12, and an automatic dialing means 13 that makes a call to the telephone number stored in the number storage means 10 when the telephone line 7 is in a call state and there is no emergency input. A voice message sending means 14 which sends out a voice message for emergency notification at certain times; an automatic call receiving means 15 which puts the telephone line 7 into a talking state when a calling signal sent through the telephone line 7 is detected; and an automatic call receiving means 15. When there is a detection output from the emergency input detection means 12, the answering set switch 6 is connected to the side where the automatic call receiving means 15 is connected to the telephone line 7. It has forced switching means 16 for forcibly switching. The number storage means 10 stores the telephone number of the person to whom the emergency call should be made, and examples of the person to whom the emergency call should be made include not only the above-mentioned pager, but also an acquaintance's home, place of work, a manager's office, and the like. Also, depending on the contents of the emergency input, the destination may be a security insurance company, gas company, fire department, etc. Automatic dialing means 1 for making a call to such reporting destination
3, a general-purpose one can be used. The various sensors 11 include the fire sensor 1, gas leak sensor 2, security sensor 3, etc. as described above, and are appropriately placed indoors. The emergency input detection means 12 instructs the automatic dialing means 13 to perform an emergency notification operation when there is an emergency input from any of the various sensors 11. When the other party responds via the telephone line 7, the voice message sending means 14 sends out a voice message for emergency notification. The voice message sending means 14 is composed of a voice synthesis LSI, a recording tape playback means, and the like. If the destination does not respond after waiting for a certain period of time, the automatic dialing means 13
The telephone line 7 is temporarily opened and a call is made again to the same reporting destination or another reporting destination. On the other hand, when there is a detection output from the emergency input detection means 12, the absentee set switch 6 is forcibly switched to the absent home monitoring mode by the forced switching means 16. Therefore, when a call is received from outside at the timing when the automatic dialing means 13 opens the telephone line 7, the automatic call receiving means 15 operates and the telephone line 7 is put into a talking state. At this time, the voice message transmitting means 14 transmits a voice message for emergency notification via the telephone line 7, since there is an emergency input and the telephone line 7 is in a busy state. When an emergency input is made through the above operations, whether or not the answering set switch 6 has been pressed in advance, when a call comes from outside, the call is automatically received to notify the contents of the emergency input. It is something that can be done.
