Abstract

An automatic window provided with a sound recognition device for the prevention of noise, which comprises a noise inputting unit (5), a sound recognition device (1), a central control unit (4), a window opening and closing device (2) and a window (3). Analysis is effected by the sound recognition device (1), in which sounds to be removed have been registered, whereby the central control unit (4) closes the window (3) to effectively remove noises which have been registered in the sound recognition device (1).

Description

Technical field

Present invention is about the opening or shutting control unit for the automatic window or automatic door.

Background Art

Japanese unexamined patent application no. P-A47-82267, i.e. Tokukai-Shou 47-82267, was disclosed in Japan.
It is about an automatic window for prevention of noise.
The purpose of this former invention is an automatic opening and shutting of the window, detecting the noise of the airplane.
Japanese unexamined patent application no. JP-A3-81487, i.e. Tokukai-Hei 3-81487, was disclosed in Japan.
It is about an opening and closing unit which uses a sound sensor and sound detecting circuit.
The purpose of this former invention is closing the window, detecting the sound of hail, and noting when it is hail.
In the first former technology, the following judgement is lacking.
The judgement that the sound from the outside is the sound of an airplane, or not in this way, the automatic window may close, detecting the sound from a car for example which runs nearby.
The automatic windows used in the school may close, detecting the voice ot the students who are playing sport in the ground, or, detecting the sound of a broadcast in the school ground.
In the second technology, the following judgement lacks.
The judgement that the detected sound is a sound of hail or not.
Due to these defects misoperation may arise. That is to say, the machine may be activated by a sound other than hail.
Present invention tries to solve the above problem using the recent technology of speech recognition.
"Microsoft Windows Sound System" is an example of sound recognition technology.

Disclosure of Invention

Present invention is an automatic window provided with a sound recognition unit for prevention of noise, which comprises an input unit 5 of noise from an outside, a sound recognition unit 1 that analyzes whether the sound is a registered noise or not, a window 3, a window driving unit 2 and a central processing unit 4 that gives the window driving unit 2 an instruction "Open the window" or "Close the window" according to a signal of the sound recognition unit 1.
When an external noise enters the input unit 5 of the noise, the central processing unit 4 judges whether the input noise is a registered noise (for example, a noise of an airplane) or not, using an analysis of the sound recognition unit 1. If the noise is a registered one, the central processing unit 4 gives the window driving unit 2 the signal of "Close the window" and the window 3 closes. While the noise of the airplane is over pre-set sound volume window 3 is closed. If its noise decreases in volume the central processing unit 4 gives the window driving unit 2 the signal to " Open the window" and window 3 opens.
When voices of pupils enter the input unit 5 of the noise, the central processing unit 4 judges that it is not a registered noise, using the analysis of the sound recognition unit 1 that compares input noise with registered noise. Window 3 stays open.

Best Mode for Enforcement of Invention

The input unit 5 of noise comprises mike and so on.
The window driving unit 2 comprises a motor and so on. It is possible to apply present invention to schools, apartment, houses, and hospitals.
Present invention can cope with various noises which are registered in advance.
If the noise ot an airplane is registered on the sound recognition unit 1, the windows or doors of a house near airport or under the route of airplanes close automatically.
If the noise of the super express "Hikari" or other trains are registered, the windows or doors of houses along the route of the trains are closed automatically. The unit will only detect the noise of the super express "Hikari" or other trains.
For areas that are near both the airport and the route ot the super express "Hikari", if both the noises of the airplane and the super express "Hikari" are registered, present invention can cope with both noises.
Present invention can also be applied to the prevention of noise from factories. If noise from a factory is registered, present invention can cope with it. That is, the windows are closed automatically, when the noise of the factory arises. The window opens automatically, when the noise stops.
When the noise arises intermittently, the window will open or close automatically according to its noise.
If present invention is applied to the panels of the root ot a hothouse and the sound of hail is registered in the sound recognition unit 1, the plants in the hothouse can be protected by closing the panels of the roof of the hothouse automatically.
Due to the tact that both airplanes, the super express "HIKARI" run to a set time schedule, these times can be programmed into the central processing unit 4.
These time schedules are very time schedules of their noise.
For example, at the place where super express passes at 10:00 AM, the central processing unit 4 can close the window 3 between 9:55 AM and 10:05 AM.
In this way, even if the input unit 5 of noise or the sound recognition unit 1 becomes out of order, the windows will still be opened or closed automatically when present invention is used in a coffee house or a private house, on line connection of the central processing unit 4 can be made to an audio machine (for example, stereo) or a radio, a wire broadcasting unit in this way, it is possible to output background music or multiply the volume of the sound of the music and at the same time have the windows closed, when the external noise is detected.
When we apply present invention to a hospital, it is convenient for the patients who are disabled, as opening or closing windows is automatic.
When we apply present invention to a private house, it is convenient for elderly people for the same reason.
Present invention is convenient for the elderly.
If we register the noise of the super express "Hikari" when it rains, automatic opening and closing of the windows becomes accurate, when it rains. If we use rain sensor (not illustrated), the central processing unit judges that it is rain, using a signal of rain sensor and keeps the window closed, when it rains.

Industrial availability

We can effectively exclude registered noises, because the central processing unit 4 closes the window 3 using the analysis of the sound recognition unit 1 which registers sounds that we want to exclude.
Using this invention, we can open or close the window automatically, allowing, the air of the room to exchange, and preventing ticks and mold. We can reduce the allergies that creates allergic reactions to people.
The windows will remain open for sounds that are not registered on the sound recognition unit 1, in this way, hearing the voices of their children playing outdoors, parents inside can take care of their children.
If we set one sound recognition unit on flats or apartment house and its signal is delivered to each room, we can realize present system economically.

Claims
