Description

[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security glass and a security system using the security glass, and a glass that reliably issues an alarm when the glass is broken and informs the neighborhood of intrusion, and takes time until an intruder enters. The present invention relates to a system that prevents damage by preventing intrusion by configuring.
[0002]
2. Description of the Related Art In recent years, there has been an increase in invasion thefts that infiltrate houses and offices and steal cash and valuables. In addition, the number of people who are noticed by people in their homes when they invade, leading to robbery and murder is increasing. Most of the intrusion comes from the window glass, and it breaks through the window glass without making a loud noise using a screwdriver, unlocks the sash crescent, enters even if it makes a loud sound, and the window glass with a bar In many cases, cash and valuables are stolen in a short time.
In conventional security systems for detecting breakage of glass, there is an ultrasonic sensor that is directly attached to the glass surface and detects and reports the sound when the glass breaks. In many cases, it malfunctions due to vibration when it hits. In order to detect the opening and closing of the window, a reed switch operated by a magnet is attached to the sash door and the sash frame to detect the opening and closing. However, a malfunction may occur due to the wind of the sash door.
[0004]
Even if these sensors detect intrusions, the window glass was easily destroyed, and in many cases, the housewares were infiltrated into the room in a short period of time, and household goods were stolen.
[0005]
In order to lengthen the time until intrusion, laminated glass using a special interlayer film or laminated glass with a transparent resin such as polycarbonate sandwiched between interlayer films may be used, but the cost increases. In some cases, it took a long time to get in.
[Problems to be solved by the invention]
[0006]
In order to prevent intrusion, first of all, it is necessary to have a detection means that does not malfunction.On the other hand, intruders may give up intruders when there are signs of people around them or when a loud alarm sounds However, if it can enter in a short time, it will intrude. For this purpose, it is necessary to construct a glass that is intimidated by a loud alarm sound and a powerful light at the same time as the glass breaks and takes time to enter.
[Means for Solving the Problems]
[0007]
In view of the above problems, the present invention provides a plurality of types of security devices including at least a detection device, an alarm unit that transmits a change in the surrounding environment detected by the detection device, and a transmission unit that transmits the change to an external monitoring center. In the security system comprising the window glass, the detection device is a window glass having a translucent conductive film, and the resistance value of the conductive film is detected through an electrode provided at an end of the window glass plate. The main feature is to detect the breakage.
[0008]
According to the above configuration, in order to reliably detect the glass breakage, by using the glass having a transparent conductive film, by detecting the resistance value change of the conductive film through the electrode provided at the end of the glass plate, A detection means without false alarms is realized.
[0009]
Also, since the glass has a transparent conductive film, it is not noticed that there is a sensor in the burglar, and the glass is broken against the burglar because the electrode is hidden in the sash and is not noticed. The intimidating effect is further increased if a loud alarm is sounded at the moment.
[0010]
Laminated glass that uses glass with a transparent conductive film for the outdoor glass and a resin film or resin plate that is difficult to break for the intermediate film in order to break the glass and take time to penetrate. Can be made. Moreover, the glass which has a transparent conductive film on the outdoor side with a multilayer glass can be used, and the indoor side can also be made into a laminated glass. For this reason, at first, when the glass having the transparent conductive film is broken, the threat starts with a loud alarm sound or a powerful light, and then it takes time to break the glass.
[0011]
FIG. 1 is an explanatory diagram showing an outline of the present invention. 1 is a window glass using a glass having a transparent conductive film, 2 is a detection device for detecting a change in the resistance value of the glass, 3 is connected to the detection device, and is composed of a siren or a flashlight installed outdoors. The alarm device 4 is a camera installed near the glass window, and is connected to the detection device 2 so as to start image storage when the glass breaks and the detection device is activated. Reference numeral 5 denotes a security device (home controller) having transmission means for transmission to an external monitoring center, which is connected to the call center 8 via a telephone line.
[0012]
At the same time as the glass breaks, an alarm device consisting of a siren or flashlight is activated, threatening intrusion. At the same time, the camera operates and records an image. An intrusion thief completely destroys the glass and takes time to enter the room, so images taken by the camera during this period can be sent to the contractor's mobile phone as an attached file by ADSL or the like. At this time, the contractor can also access the camera by describing the URL of the server storing the image in the mail.
[0013]
In the call center 8, by means of a report from the security device (home controller) 5, the fact that there is an abnormality in the order designated by the contractor is sequentially notified. The contractor can confirm the indoor situation by e-mail or contact from the call center, and can request the police to dispatch.
[0014]
At the same time when the glass breaks, an alarm device consisting of a siren or flashlight is activated, threatening the burglar, so that the glass window is difficult to break, and when it seems that it takes time to break in, the burglar gives up the break Damage can be prevented.
[0015]
2 to 5 show the structure of the glass used in the present invention. 2 shows a single glass plate, FIG. 3 shows a laminated glass, FIG. 4 shows a multi-layer glass, and FIG. 5 shows a form of a sliding sash. The detection device is a window glass 11 having a translucent conductive film, and breakage of the window glass is detected by detecting a change in the resistance value of the conductive film 12 through an electrode provided at an end portion of the window glass plate. .
[0016]
If the window glass with a light-transmitting conductive film is made of tempered glass, it breaks down when the glass breaks, and the resistance value of the conductive film becomes infinite. The device can be connected directly.
[0017]
In addition, by using glass having a plurality of light-transmitting conductive films and detecting glass breakage twice, it is possible to reliably detect intrusion and to report to the police.
【The invention's effect】
Since the present invention is configured as described above, detection without false alarms is possible in order to detect glass breakage. In addition, by using a transparent conductive film, the presence of the sensor is not noticed in the burglar, and the electrode is hidden in the sash and is not noticed. A sound is produced and the threatening effect can be increased. Furthermore, by making the glass form laminated glass or multilayer glass, it takes time to break the glass, and the crime prevention effect is high.
