  Hereinafter, a laminated structure with a crime prevention function according to an embodiment of the present invention will be described with reference to the drawings.

  The laminated structure with a crime prevention function according to an embodiment of the present invention is used as a building material for a house door in the present embodiment. As shown in FIGS. 1 and 2, the door 1 has a rectangular frame 10 made of a strong insulating material having a substantially U-shaped cross section, and one opening 11 of the frame 10, that is, the door 1 is installed in a residence. In such a state, the electrode plate 20 attached to close the opening 11 toward the outside of the residence and the other opening 12 of the frame 10, that is, the opening 12 toward the inside of the residence with the door 1 installed in the residence. It has the inner wall board 30 attached so that it may block.

  A certain amount of space is formed between the electrode plate 20 and the inner wall plate 30, and a driver unit 40 for generating a warning sound is provided on the back surface of the electrode plate 20 in this space. In addition, a detection unit box 50 for providing a threatening function to a suspicious person of the laminated structure with a crime prevention function according to the present invention is provided.

  In this embodiment, the electrode plate 20 has a laminated structure in which a polyethylene plate 25 made of a dielectric (insulator) thin plate is sandwiched between aluminum plates 21 and 22 made of two thin plates which are conductors. A capacitor is formed by the structure. The electrode plate 20 functions as a variable capacitor whose ground capacitance changes as the human body approaches or separates.

  In the present embodiment, the electrode plate 20 includes two aluminum plates 21 and 22 and a polyethylene plate 25 having a size and thickness suitable for detecting the approach and contact of the human body with high sensitivity. . At present, a laminated structure plate for building materials that can be used as such an electrode plate 20 is known to have a thickness of 1.2 mm to 6.0 mm. A laminated structure plate may be used as appropriate, and a laminated structure plate other than the laminated structure plate having such a thickness may be used for the electrode plate 20. The electrode plate 20 has a lower end that is, for example, about 40 cm away from the ground, and is suitable for detecting the approach and contact of the human body with high sensitivity when the electrode plate 20 is fixed on the front surface of the electrode plate 20 without any person, for example. It has a capacitance of about 100 pF.

  Thus, the electrode plate 20 is easy to manufacture because it is made of a material having a laminated structure in which the polyethylene plate 25 is sandwiched between the aluminum plates 21 and 22 and having excellent workability. Moreover, such a laminated structure used as a normal building material can be used as the electrode plate 20, and the manufacturing cost can be suppressed.

  The driver unit 40 vibrates the electrode plate itself and generates a warning sound from the entire door. And this makes it function enough to threaten suspicious individuals. As the driver unit 40, for example, the driver unit described in Japanese Patent No. 3808015 is used. Any driver unit that vibrates the entire electrode plate to generate a warning sound and threaten a suspicious person can be used. Such a driver unit may be used. That is, even if the driver unit 40 is a general driver unit used for sounding a large speaker, it can be used as long as it can generate a warning sound by vibrating the relatively rigid electrode plate 20. It is. In the present embodiment, the driver unit 40 is supplied with driving power from inside the house via the electric wire 41. However, a battery or the like may be arranged adjacently to supply driving power. Moreover, in addition to the drive power being supplied from the house via the electric wire 41, a backup battery as a power failure countermeasure may be provided.

  The detection unit box 50 includes an intimidating sound signal generation circuit 100 shown in FIG. 3. The intimidating sound signal generation circuit 100 is electrically connected to the electrode plate 20 by an electric wire 51, and is connected to the driver unit by an electric wire 41. 40 is also electrically connected, and when a person approaches the electrode plate 20, a change in ground capacitance of the electrode plate 20 is detected, and a threatening sound generation signal having a frequency corresponding to the amount of change in the ground capacitance is sent to the driver unit 40. It is like that.

  The threatening sound signal generation circuit 100 of the detection unit box 50 is as shown in FIG. This operation will be described in detail below.

  FIG. 3 is a block diagram showing a configuration of the oscillation control type threatening sound signal generation circuit 100 used in the laminated structure with a crime prevention function according to the present embodiment.

  The threatening sound signal generation circuit 100 includes a reference oscillator 110, a dividing circuit 120, a comparison circuit 130, a voltage control oscillator 140, a buffer amplifier 160, and a power amplifier 170.

  The divided circuit 120 is connected to one aluminum plate 22 (outside the door) of the electrode plate 20, and the other aluminum plate 21 (inside the door) of the electrode plate 20 is grounded (grounded). In the case of the present embodiment, the power amplifier 170 is connected to a speaker 180 including the driver unit 40 and the electrode plate 20. In FIG. 3, for convenience of illustration, the electrode plates 20 are shown in two places, but in the present embodiment, this is shared and configured as one electrode plate 20.

  When the door is provided with a door knob or a small view window for viewing the outside from the room, it is necessary to attach these via an insulating material such as rubber so as not to short-circuit the opposing aluminum plates of the electrode plate 20. Is done.

  In addition, it is required to be careful not to short-circuit between the ground and the aluminum plate 22 outside the door with, for example, a metal tool.

  As described above, the electrode plate 20 functions as a variable capacitor whose ground capacitance changes when a suspicious person approaches or separates his / her hand, and serves as a human body sensor. This is because the human body is a kind of conductor.

  The reference oscillator 110 is a frequency variable oscillator for controlling the pitch of intimidating sounds, and is composed of an oscillator whose frequency can be changed by changing the capacitance of the capacitor C, such as an LC oscillator or a CR oscillator. The reference oscillator 110 generates a signal that oscillates at a predetermined reference frequency corresponding to the ground capacity when no person is present on the front surface of the electrode plate 20. The practical range of the oscillation frequency of the reference oscillator 110 is determined by the capacitance of the electrode plate 20 and is, for example, about 100 kHz to 1 MHz.

  The signal output from the reference oscillator 110 is directly sent to a comparison circuit 130 having a common mode amplifier and a detector, and is also sent to a dividing circuit 120 for detecting proximity to humans. The dividing circuit 120 generates an output different from the output from the reference oscillator 110 according to a change in the ground capacity of the electrode plate 20 by a person approaching or contacting the electrode plate 20, and this is output to the comparison circuit 130. Send output. The comparison circuit 130 outputs an output difference ΔV that changes in accordance with the difference between the output of the reference oscillator 110 and the output of the dividing circuit 120, that is, the approaching degree or the contact degree of a person approaching the electrode plate 20. It is sent to the voltage controlled oscillator 140.

  A voltage controlled oscillator 140 called a VCO (Voltage Controlled Oscillator) performs voltage-frequency (VF) conversion, and generates a signal that oscillates at an audible frequency band frequency (about 20 Hz to 15 kHz) corresponding to the output difference ΔV. It is like that. The signal generated by the voltage controlled oscillator 140 is sent to the driver unit 40 via the buffer amplifier 160 and the power amplifier 170. The buffer amplifier 160 prevents the oscillation frequency of the voltage controlled oscillator 140 from fluctuating by the power amplifier 170 as a subsequent stage, and includes a timer therein.

  The timer is used, for example, to determine whether or not an output difference ΔV equal to or greater than a certain threshold has continued for a certain time. As a result, for example, the degree of approach to the door 1 when the visitor rings the doorbell does not result in an output difference ΔV that is greater than or equal to this threshold, and even if the visitor touches the door for a short period of time, it does not exceed the certain threshold. The output difference ΔV does not continue for a predetermined time defined by the timer, and in such a case, a warning sound is not generated.

  On the other hand, if a suspicious person leans forward on the front of the door 1 to break the keyhole or touches the keyhole of the door 1 for a certain period of time, the output difference ΔV exceeding a certain threshold has continued for a predetermined time. Is detected by a timer, the output difference ΔV is sent to the power amplifier 170, and the driver unit 40 is driven based on the output difference ΔV corresponding to the change in the ground capacity of the electrode plate 20 according to the movement of the suspicious person. The entire electrode plate is vibrated to generate a warning sound and intimidate the suspicious person.

  Next, the effect | action of the laminated structure with a crime prevention function comprised as mentioned above is demonstrated more concretely. In addition, this laminated structure with a crime prevention function is used as a building material for a house door in this embodiment as described above. Here, when a switch (not shown) is turned on, the reference oscillator 110 starts oscillating at a frequency corresponding to the prescribed ground capacity of the electrode plate 20.

  In this state, for example, when the suspicious person approaches the residence and the hand of the suspicious person approaches or comes into contact with the electrode plate 20 to break the key of the door handle, the ground capacity of the electrode plate 20 changes, and the reference Unlike the reference signal from the oscillator 110, an output that changes in accordance with the degree of approach or contact of the suspicious person's hand to the door is output from the dividing circuit 120 to the comparison circuit 130. Then, the comparison circuit 130 obtains an output difference ΔV between the output of the reference oscillator 110 and the dividing circuit 120, and based on the output difference ΔV, the voltage controlled oscillator 140 is audible band corresponding to the output difference ΔV sent from the comparison circuit 130. And a signal is sent to the power amplifier 170 via the buffer amplifier 160, and the driver unit 40 is driven to vibrate the entire electrode plate.

  The buffer amplifier 160 has a built-in timer so that the output difference ΔV is sent to the power amplifier 170 only when the output difference ΔV exceeding a certain threshold value continues for a certain time. As a result, for example, when the visitor rings the doorbell, the output difference ΔV is not more than this threshold at the degree of approach to the door, and even if the visitor touches the door for a short time, the output exceeds the certain threshold. The difference ΔV does not continue for a predetermined time or more specified by the timer, and in such a case, a warning sound can be prevented from being generated.

  On the other hand, if a suspicious person is crouching on the front of the door for a long time to break the keyhole or touching around the keyhole of the door for a certain period of time, the timer indicates that the output difference ΔV exceeding a certain threshold has continued for a predetermined period of time. And the output difference ΔV corresponding to the movement of the suspicious person is transmitted to the power amplifier 170 and amplified, the amplified warning sound signal is transmitted to the driver unit 40, and the driver unit 40 is driven to cooperate with the driver unit 40. The entire electrode plate constituting the speaker 180 is vibrated to threaten the suspicious person as a warning sound whose frequency (pitch) changes according to the movement of the suspicious person. This makes it possible to surprise the suspicious person and dismiss him from the spot.

  Then, the laminated structure with a crime prevention function concerning the modification of embodiment mentioned above is demonstrated. Note that the laminated structure with a crime prevention function according to this modification is different from the embodiment described above for only a part of the threatening sound generation signal processing circuit, and other configurations of the electrode plate 20 and the driver unit 40 are the embodiments described above. Therefore, detailed description of common parts is omitted.

  As shown in FIG. 4, the threatening sound signal generation circuit 200 includes a reference oscillator 210, a dividing circuit 220, a comparison circuit 230, an audible sound oscillator 250, a buffer amplifier 260, and a power amplifier 270.

  The divided circuit 220 is connected to the aluminum plate 22 forming one electrode (outside of the door) of the electrode plate 20, and the aluminum plate 21 forming the other electrode (inside the door) of the electrode plate 20 is grounded. ing. In the case of this modification, the power amplifier 270 is connected to a speaker 280 including the driver unit 40 and the electrode plate 20. In FIG. 4, the electrode plate 20 is shown in two places for convenience of illustration and explanation, but the electrode plate 20 is configured as one electrode plate also in this modification.

  As described above, the electrode plate 20 functions as a variable capacitor whose ground capacitance changes when a suspicious person moves his hand close to or away from the electrode plate 20 or touches his / her hand, and can be considered as a human body sensor. This is because the human body is a kind of conductor.

  In this modification, the reference oscillator 210 is a frequency variable oscillator for controlling the volume of a threatening sound, and is composed of an oscillator whose frequency can be changed by changing the capacitance of the capacitor C, such as an LC oscillator or a CR oscillator. The reference oscillator 210 generates a signal that oscillates at a predetermined reference frequency corresponding to the ground capacity when no person is present on the front surface of the electrode plate 20. The practical range of the oscillation frequency of the reference oscillator 210 is determined by the capacitance of the electrode plate 20, and is about 100 kHz to 1 MHz, for example, as in the above-described embodiment. The signal output from the reference oscillator 210 is sent directly to the comparison circuit 230 and also sent to the dividing circuit 220.

  The dividing circuit 220 generates an output different from the output from the reference oscillator 210 in response to a change in the ground capacity when a person approaches or contacts the electrode plate 20, and sends this output to the comparison circuit 230. It has become.

  The comparison circuit 230 outputs an output difference ΔV that changes instantaneously according to the difference between the output of the reference oscillator 210 and the output of the dividing circuit 220, that is, the degree of approach or contact of the person to the electrode plate 20, and this output difference ΔV Is sent to the buffer amplifier 260. The buffer amplifier 260 is configured such that the oscillation frequency of the comparison circuit 230 is not changed by the power amplifier 270 which is a subsequent stage, and has a built-in timer.

  Similar to the above-described embodiment, the timer is used to determine, for example, whether or not an output difference ΔV equal to or greater than a certain threshold value has continued for a certain time. Thus, for example, when the visitor rings the doorbell, the output difference ΔV is not more than this threshold when the door 1 is approached. Also, even if the visitor touches the door 1 for a short period of time, it exceeds this fixed threshold. The output difference ΔV is not continued for a predetermined time specified by the timer, and in such a case, a warning sound is not generated.

  On the other hand, if a suspicious person is crouching on the front of the door for a long time to break the keyhole or touching around the keyhole of the door for a certain period of time, the timer indicates that the output difference ΔV exceeding a certain threshold has continued for a predetermined period of time. Is sent to the power amplifier 270 as a threatening sound signal.

  Also, an audible sound oscillator 250 connected to the buffer amplifier 260 is called an AFO (Audio Frequency Oscillator), and has a constant frequency and an amplitude that changes according to the output difference ΔV. The constant frequency amplitude generated at 250 is changed according to the output difference ΔV. The output from the audible oscillator 250 whose amplitude has changed due to the output difference ΔV is amplified by the power amplifier 270 only when the output difference ΔV of a certain threshold value or more is detected by the timer of the buffer amplifier 260 for a certain period of time. To be sent to. Then, by driving the driver unit 40 in response to the output difference ΔV corresponding to the change in the ground capacity of the electrode plate 20, a warning sound that changes the sound volume is generated by vibrating the electrode plate 20 as a whole. To threaten suspicious people.

  Even if the door using the laminated structure with a crime prevention function according to such a modification is attached to a house, the same effect as the above-described embodiment is exhibited. That is, when the suspicious person approaches the residence and the hand of the suspicious person approaches or comes into contact with the electrode plate 20 to break the keyhole of the door, the ground capacity of the electrode plate 20 changes, and the dividing circuit 220 is separated from the reference oscillator 210. The input reference signal is changed accordingly, and an AC signal having a voltage corresponding to the amount of change in the ground capacity is sent to the comparison circuit 230. The comparison circuit 230 sends an output difference ΔV between the output of the dividing circuit 220 and the output of the reference oscillator 210 to the buffer amplifier 260, and outputs the amplitude of the constant frequency generated by the audible sound oscillator 250 connected to the buffer amplifier 260 as the output difference ΔV. It changes according to.

  Since the buffer amplifier 260 has a built-in timer, it is determined whether or not the output difference ΔV exceeding a certain threshold has continued for a certain time. As a result, for example, when the visitor approaches the door when ringing the doorbell, the output difference ΔV is not more than this threshold value, and even if the visitor touches the electrode plate 20 around the door for a short time, this constant is maintained. In such a case, the warning sound is not generated without the output difference ΔV exceeding the threshold value of V being continued for the predetermined time or more specified by the timer.

  On the other hand, if a suspicious person is crouching on the front of the door for a long time to break the keyhole or touching around the keyhole of the door for a certain period of time, the timer indicates that the output difference ΔV exceeding a certain threshold has continued for a predetermined period of time. The output signal from the audible sound oscillator 250 whose amplitude is changed by the output difference ΔV according to the movement of the suspicious person is amplified by the power amplifier 270 and transmitted to the driver unit 40 as a warning sound signal, and the driver unit 40 is driven. As a result, the entire electrode plate constituting the speaker 280 is vibrated in cooperation with the driver unit 40, and the suspicious person is threatened as a warning sound whose volume changes according to the movement of the suspicious person.

Note that the door using the laminated structure with a crime prevention function according to this modified example is intimidating the suspicious person by changing the sound volume of the entire door according to the movement of the suspicious person. The difference is that it changes the pitch of the warning sound that the whole door reports according to the suspicious person's movement, but both can be intimidated by an unexpected threatening method and the same in terms of dissipating Demonstrate the effect.

  Moreover, in this modification, it can be said that it is preferable from the point of threatening a suspicious person that signal processing is performed so that the volume of the warning sound increases as the suspicious person approaches the electrode plate 20.

When a door using a laminated structure with a crime prevention function having the above configuration is used as a door of a house, for example, when approaching a suspicious person's house, the suspicious person has a conventional infrared sensor or security camera. First check and confirm that it is not installed, then approach the door that is easy to enter. After a suspicious person approaches this door, if the ground capacity of the electrode plate changes and exceeds a predetermined threshold value and the output difference ΔV exceeds the level of visitors at night, the output The driver unit is driven according to the difference ΔV to vibrate the laminated structure itself and emit a warning sound.

  The whole door emits a warning sound that changes the pitch and volume according to the suspicious person's movement by vibrating the whole electrode plate, and the suspicious person is surprised by the sudden warning sound from the whole door. Retreat.

  Even if the suspicious person does not dissipate with respect to the warning sound in this way, the threatening sound generated by the electrode plate 20 according to the amount of change ΔV corresponding to the degree of approach or contact of the human body to the electrode plate 20 Since the pitch and volume also change, you can give the suspicious person the fear of being barked by a dog or beast from darkness, and the suspicious person can not stay on the spot Let

As explained above, the existence of external-type security cameras, infrared sensors, etc. as before is immediately recognized by the suspicious person, so the suspicious person can break into the house after breaking it, for example However, in the door using the laminated structure with security function according to the present invention, it appears from the whole door as the suspicious person approaches the door without seemingly realizing that the security function device is provided. Since the pitch and volume of the warning sound to be changed changes, the suspicious person cannot understand which part of the door breaks when this warning sound stops, and the closer the hand is to the door trying to break the door, the more the warning sound Since the pitch and volume change and become conspicuous, the suspicious person is forced to dissipate.

In this way, the door using the laminated structure with a crime prevention function according to the present embodiment can prevent the suspicious person from entering the residence and surely prevent the suspicious person accustomed to the illegal intrusion. Can also give a deterrent to intruders.

  In addition, as shown as dotted line A1-A3 of FIG. 5, such a laminated structure with a crime prevention function is used in order to detect the approach of a suspicious person to the door D of a house (refer dotted line A1 in the figure). The embodiment is not limited. That is, for example, this laminated structure with a crime prevention function may be used as a building material on the wall surface around the sash S of a house (see dotted line A2 in the figure). Even in this case, it is possible to effectively prevent a suspicious person from breaking the sash S and entering the residence.

  Furthermore, by using such a laminated structure with a crime prevention function on the outer wall W of the house (see dotted line A3 in the figure), not only prevents suspicious people from illegally entering at night, but also graffiti on the wall at night. It can also prevent the drunks from standing on the wall at night and pissing.

  In addition, when using this laminated structure with a crime prevention function for the wall D of the above-mentioned house, the wall near the sash S, and the outer wall W, it is preferable that this lower end is separated from the ground by about 40 cm to 50 cm or more. By installing in this way, when a dog, a cat, or the like walks around the dwelling, this laminated structure with a crime prevention function can detect these erroneously and prevent a threatening sound from being generated.

  Moreover, you may utilize such laminated structures with a crime prevention function for outer panels, such as a door panel of a cash transport vehicle of vehicles, side panels other than a door, a bonnet, and a roof panel. By doing so, it is possible to threaten the suspicious person by generating a warning sound and suddenly vibrating the whole door or a part of the outer panel when the suspicious person approaches during the transportation of cash or at the time of transportation.

  Moreover, you may install such a laminated structure with a crime prevention function in the right place in the door in the welfare care facility called a care home, for example. By using such a method, it is possible to effectively prevent a night habit inside a facility of a care home resident who has been a problem in recent years and going out without permission outside the facility.

  Moreover, you may attach such a laminated structure with a crime prevention function to the door and wall in the facility which imprison a specific person. By using such a method, it is possible to prevent an imprisoned person from leaving the facility without permission.

  Moreover, you may utilize such a laminated structure with a crime prevention function for the purpose different from crime prevention in a hospital. Specifically, in the past, it was impossible to notify the outside of the patient in the toilet without pressing a push button such as a nurse call when the patient was abnormal, but the laminated structure with a crime prevention function according to the present invention is not provided. If it is installed on the wall in the toilet of such a hospital, the patient's condition in the toilet suddenly deteriorates and the electrode plate that forms part of the wall of the toilet falls on the wall in the toilet. By detecting the approach and contact, it is possible to promptly notify the nurse center of this dangerous state even in a state where the patient loses his mind.

  The laminated structure with the crime prevention function described above is attached to the driver unit on the electrode plate itself serving as a human body detection capacitor and vibrates the electrode plate itself, but is not necessarily limited to this. A speaker that issues a general warning sound may be installed in the vicinity, and a warning sound may be generated from this external speaker when a suspicious person is detected.

  By doing so, it is possible to exert a sufficient threat effect. However, if the electrode plate itself is vibrated to generate a warning sound as in the present embodiment, a sufficient effect can be exhibited with respect to making the suspicious person creepy, and the crime prevention function can be further enhanced.

  In addition to using the electrode plate itself as a speaker as described above, the crime prevention function may be further enhanced by illuminating a place where a suspicious person exists with a spotlight.

  Also, for example, when installing this laminated structure with a security function on a door or a wall surface, a plurality of laminated structures with a security function are installed side by side, and each generates a warning sound independently according to the approach or contact of a suspicious person. Also good. By doing in this way, a warning sound can be generated from various places on the door and wall according to the movement of the suspicious person, and the threatening effect on the suspicious person can be further enhanced.

  In addition, the material which comprises the electrode plate mentioned above is not limited to the aluminum plate and the polyethylene plate (polyethylene resin) pinched | interposed into this. That is, any electrode plate capable of exhibiting the action of the present invention, that is, an electrode plate whose capacity changes according to the distance from the human body, can be replaced with a good conductor such as a stainless steel plate or a copper plate instead of an aluminum plate. Needless to say, it is possible to use an electrode plate formed by sandwiching an insulator made of a resin such as polystyrene or an inorganic material such as mica with a metal made of the above. In addition, it can be set as the laminated structure with a crime prevention function which is excellent in intensity | strength and corrosion resistance and can be used over a long period of time by using a stainless steel plate as a metal plate outside an electrode plate.
