Abstract

<P>PROBLEM TO BE SOLVED: To provide an alarm sound communicator which utters continuously from a speaker or a buzzer installed at the inside of a house newly, when an alarm sound emitted by a certain crime prevention buzzer is detected from among the surrounding sounds gleaned by a microphone installed at the outdoor. <P>SOLUTION: To attain aforementioned purpose, the alarm sound communicator has a sound collection means which collects surrounding sounds and converts them into electrical signal, an alarm sound detection means which detects alarm sound that matches with a predetermined frequency component, and an information output means which informs that an alarm sound has been detected by the alarm sound detection means, and that an alarm has been continuously emitted newly from the information output means, when the desired alarm sound is detected by the alarm sound detection means from among the surrounding sound collected by the sound collection means. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

The present invention relates to an alarm sound alarm device for notifying an emergency situation.

A security buzzer that emits a loud alarm is widely used as a means of notifying people in the vicinity of an emergency situation.

The only person who can hear the alarm sound and recognize the occurrence of an emergency is the person who can hear the alarm sound. It becomes more difficult to hear than outdoors. Also, if there is room noise, it is difficult to hear.

Therefore, the present invention continues the alarm sound produced by a certain security buzzer from the speaker or buzzer installed indoors when the surrounding sound is collected by a microphone installed outdoors and the alarm sound is detected from the sound. An object is to provide an alarm sound alarm that newly generates an alarm sound.

In order to achieve the above object, an alarm sound alarm according to the present invention comprises a sound collecting means for collecting surrounding sounds and converting them into an electrical signal, and an alarm sound detecting means for detecting an alarm sound that matches a predetermined frequency component. , Having a notification output means for notifying that it has been detected by the warning sound detection means, and detecting a desired warning sound by the warning sound detection means from the surrounding sounds collected by the sound collection means, Subsequently, a new alarm is issued from the notification output means.

It further has sound signal transmission means for extending a transmission path from the sound collection means to the alarm sound detection means.

It further has a detection signal transmission means for extending a transmission line from the alarm sound detection means to the notification output means.

Even if it is difficult to hear the alarm sound of the security buzzer sounding outdoors, it is possible to recognize the occurrence of an emergency as if it was difficult to hear.

An alarm sound alarm according to the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an outline of a device configuration in the embodiment. The microphone 110 of the sound collecting means 100 collects outdoor ambient sounds and converts them into electric signals, which are further amplified by the sound amplifying unit 120. Moreover, since the sound collecting means 100 is intended to collect outdoor sounds, it is naturally installed outdoors.

The alarm sound detecting means 300 passes the sound electric signal through the band-pass filter 310 in order to detect the desired alarm sound from the surrounding sounds collected by the sound collecting means 100, and thereby the desired alarm sound. Is detected. A detection signal indicating the detection is sent to the notification output means 500.

The band-pass filter 310 of the alarm sound detection means 300 is detected by a filter method for processing an acoustic signal as it is, and an analog signal is converted into a digital signal by using an A / D converter and detected by a filter calculation process by a CPU. There is also a way to do it.

The notification output means 500 emits a new alarm sound using a buzzer 520 or a speaker to notify people in the room. The output control unit 510 controls how to sound an alarm sound.

Although the sound collecting means 100 is installed outdoors and the notification output means 500 is installed indoors, the main casing including the alarm sound detecting means 300 can be installed either outdoors or indoors. When the casing is installed indoors, the sound and electrical signal from the sound collection means 100 must be extended and transmitted using the sound signal transmission means 200. When the casing is installed outdoors, the detection signal from the alarm sound detection means 300 must be extended and transmitted using the detection signal transmission means 400.

The sound signal transmission means 200 and the detection signal transmission means 400 select the transmission means according to the physical state that separates the outdoors from the indoors. If there is a space to pass the electric wire, it will be wired transmission using an electric wire. When there is no space, radio transmission using radio waves or light passing through the window glass is performed.

FIG. 2 is a diagram illustrating an outline of a usage example of the alarm sound alarm in the embodiment.
The sound insulation of buildings, condominiums, houses, etc. has increased, and the sound outside has been blocked so that it is not audible to people who are indoors. This makes it difficult to hear the alarm sound of the security buzzer. Even if a transmission line cannot be secured by an electric wire, a transmission line can be secured by adding a wireless transmitter to the sound collecting means 100 of the alarm sound alarm installed outdoors. By installing and operating an alarm sound alarm with a wireless receiver indoors, alarm sounds such as a security buzzer can be detected and recognized in the same state as when listening outdoors.

These are block diagrams which show the structure of the alarm sound alarm device by embodiment. These are figures which show the usage example outline | summary of the alarm sound alarm device by embodiment.
