Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a security device,
In particular, the present invention relates to a security device for setting and releasing security by opening and closing a curtain.

[0002]

2. Description of the Related Art Conventionally, security setting is performed by a security setting switch, and when a door closing sensor installed in a window detects that the window is opened in the security setting state, an alarm sound is emitted to perform security. Security devices have been proposed.

As shown in FIG. 2, such a security device includes a security setting switch 14 that is closed to perform security setting, a door-tight sensor 12 installed in a window 11, and an alarm device 15. It is.

The alarm device 15 includes a voice synthesizing IC 17 for synthesizing a security setting confirmation sound when security is set and an alarm sound when the door closing sensor 12 detects the opening of the window 11 under the control of the control unit 16, respectively. Voice synthesis IC17
An amplifier 18 for amplifying the confirmation sound or the alarm sound from the controller 18 and a speaker 19 for sounding the confirmation sound or the alarm sound amplified by the amplifier 18 are provided.

The operation of such a security device will be described below with reference to FIG. When the security setting switch 14 is closed by closing the window 11 to perform security setting, a security setting signal is output. When the control unit 16 receives the security setting signal, the voice synthesizing IC 17 is controlled by the control unit 16. A confirmation sound is output, amplified by the amplifier 18, and, for example, “security set” is announced from the speaker 19, and it is notified that the security is set.

When security is set by forgetting to close the window 11, the door closing sensor 12 detects the opening of the window 11 and outputs a detection signal. The control unit 16 receives the detection signal and detects an abnormality. State. Here, when the security setting switch 14 is closed, a security setting signal is output. When the control unit 16 in the abnormality detection state receives the security setting signal,
A warning sound is output from the voice synthesis IC 17 under the control of the control unit 16, amplified by the amplifier 18, and output from the speaker 19.
For example, "Window is open" is announced and window 11
Is informed that it is in an abnormal state of being opened.

Further, when the window 11 is opened by a suspicious person in the above-described security setting state, the door closing sensor 1
2 detects the opening of the window 11 and outputs a detection signal. When the control unit 16 in the security setting state receives the detection signal, an alarm sound is output from the voice synthesis IC 17 under the control of the control unit 16 and the amplifier 18 And the speaker 19 announces, for example, “the window is open”, and informs that the window 11 is in an abnormal state in which the window 11 is open.

In order to release the above-mentioned crime prevention setting state, the crime prevention setting switch 14 is closed, and this operation is detected by the control of the control unit 16 of the alarm device 15 to change the crime prevention setting state to the crime prevention release state. Will be restored.

[0009]

In a conventional security device, a security setting and a security release are set by operating a security setting switch. For this reason, the user must forget to operate the security setting switch and not enter the security setting state. There was a drawback in that the window was opened with the door open and a warning was issued by mistake.

The present invention has been made in order to solve this difficulty. Attention has been paid to closing the curtain at night, and a curtain opening / closing sensor for detecting the opening / closing of the curtain is used instead of the security setting switch. An object of the present invention is to provide a security device that does not forget security release.

[0011]

In order to achieve the above object, a security device according to the present invention comprises: a security device which detects an abnormality in a window by a door-closing sensor which detects opening / closing of the window and issues an alarm; A security device, comprising: a curtain opening / closing sensor 4 for detecting the opening / closing of a curtain, releasing the security when the curtain is open, and setting the security when the curtain is closed when the curtain is closed. .

According to such a security device, the security can be set and released by opening and closing the curtain instead of the security setting switch, so that the user does not forget to set and release the security.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of a security device according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing one embodiment of the present invention. The security device shown in FIG. 1 detects the opening and closing of the curtain on the curtain 3 that covers the window, and outputs a security release signal when the curtain is opened.
It comprises a curtain opening / closing sensor 4 for outputting a security setting signal when the curtain is closed, a door-tight sensor 2 installed in the window 1, and an alarm device 5.

The alarm device 5 includes a voice synthesizing IC 7 for synthesizing a security setting confirmation sound when security is set and an alarm sound when the door closing sensor 2 detects the opening of the window 1 under the control of the control unit 6, respectively. An amplifier 8 for amplifying a confirmation sound or an alarm sound from the voice synthesis IC 7 and a speaker 9 for sounding the confirmation sound or the alarm sound amplified by the amplifier 8 are provided.

The operation of such a security device will be described below with reference to FIG. When the window 1 is closed and the curtain 3 is closed for security setting, a security setting signal is output,
When the control unit 6 receives the security setting signal, a confirmation sound is output from the voice synthesis IC 7 under the control of the control unit 6, amplified by the amplifier 8, and, for example, “security set” is announced from the speaker 9, It is notified that it is in the setting state.

When the security is set by forgetting the closing of the window 1, the door closing sensor 2 detects the opening of the window 1 and outputs a detection signal, and the control unit 6 receives the detection signal and detects an abnormality. State. Here, when the curtain 3 is closed, the curtain opening / closing sensor 4 detects that the curtain 3 is closed and outputs a crime prevention setting signal. When the control unit 6 in the abnormal detection state receives the crime prevention setting signal, the control unit 6 Under the control, a warning sound is output from the voice synthesis IC 7, amplified by the amplifier 8, announces, for example, “the window is open” from the speaker 9, and is notified that the window 1 is in an abnormal state in which the window 1 is open. Further, in the above security setting state,
When the window 1 is opened by a suspicious person or the like, the door closing sensor 2 detects the opening of the window 1 and outputs a detection signal. When the control unit 6 in the security setting state receives the detection signal, the control unit 6 controls the control unit 6. A warning sound is output from the voice synthesis IC 7 by
The signal is amplified by the amplifier 8, the speaker 9 announces, for example, "the window is open", and notifies that the window 1 is in an abnormal state in which the window 1 is open.

In order to release the above-mentioned crime prevention setting state, the curtain opening / closing sensor 4 detects the opening of the curtain by outputting the curtain 3 and outputs a crime prevention release signal, and receives the crime prevention release signal. Control unit 6 of alarm device 5
Is restored from the crime prevention setting state to the crime prevention release state.

[0018]

As is apparent from the above description, according to the security device according to the present invention, a curtain opening / closing sensor for detecting the opening / closing of the curtain is used in place of the security setting switch, so that security setting and security release are not forgotten.
