  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a side sectional view of a vibration detecting device according to a first embodiment of the present invention, FIG. 2 is a plan sectional view of an entrance pouch provided with a vibration detecting device, and FIG. 3 is a configuration diagram of an entrance provided with the vibration detecting device, 4 is a cross-sectional view of the entrance porch provided with the vibration detection device, FIG. 5 is a cross-sectional view of the vibration detection means, and FIG. 6 is a block diagram of the detection device.

  In FIG. 1, a flexible cable-like piezoelectric sensor 7 is attached as a vibration detecting means on the surface of an elastic member such as a sponge 6, and further overlaps the piezoelectric sensor 7 at a plurality of points. As described above, aluminum round bars 8 are attached in parallel to each other at substantially equal intervals as a plurality of hard bar-like members. It is sandwiched from above and below by two resin films 9a and 9b having no water permeability so as to cover the sponge 6, the piezoelectric sensor 7 and the aluminum round bar 8, and four sides are thermally welded so that dust and water do not enter. This is a dustproof and waterproof means. Therefore, even when installed outdoors such as around a house exposed to wind and rain, highly reliable detection can be performed. Alternatively, only the piezoelectric sensor 7 may be sealed with the resin films 9a and 9b and adhered to the surfaces of the resin films 9a and 9b so as to be sandwiched between the sponge 6 and the plurality of aluminum round bars 8. Since the sponge 6 and the aluminum round bar 8 are not electrically connected to the piezoelectric sensor 7, even if a slight amount of dust or water adheres, the influence on the operation is small. However, it is preferable that no dust or water adheres.

  In addition, as shown in FIG. 2, the piezoelectric sensor 7 is meandered and the aluminum round bar 8 is arranged so as to be substantially orthogonal to the linear portion of the meandering piezoelectric sensor 7 so that one aluminum round bar is provided. 8 intersects the piezoelectric sensor 7 at a plurality of points. A control unit 11 that processes an output signal from the piezoelectric sensor 7 is connected to one end of the piezoelectric sensor 7. The control unit is configured by determination means, notification means, and the like, and is electrically connected to the piezoelectric sensor 7 by a coaxial cable 12 or the like. This determination means and notification means are housed in a dustproof and waterproof housing and detect vibration. It is arranged in the vicinity of the device 13. By installing a determination unit and a notification unit that perform signal processing on the output from the piezoelectric sensor 7 in the vicinity of the vibration detection unit, a highly reliable object that is not easily affected by external noise can be obtained.

  The operation and action of the vibration detection device 13 configured as described above will be described below with reference to FIGS.

  As shown in FIGS. 3 and 4, the vibration detection device 13 is embedded in the porch 15 outside the house, in this case, in front of the entrance door 14 which is the entrance, and the detection result output by the notification means is the display means 16 in the interior of the house. Is displayed. In addition, you may link with the other apparatus installed in the inside of a house.

  Further, the pouch 15 has a movable body 18 that is movable in a vertical direction at a part of the upper surface, particularly a portion where a person 17 stands, and the vibration detection device 13 is disposed below the vibration body 13 so that vibration applied to the movable body 18 vibrates. It is applied to the detection device 13. An O-ring 20 is disposed in the gap between the main body 19 of the pouch 15 and the movable body 18 so that dust and water enter the inside and the vibration detection device 13 does not get dust and water. Thereby, it can be set as a thing more reliable than the next by giving a double dustproof part waterproof means together with the dustproof waterproof means of the piezoelectric sensor 7. FIG.

As shown in FIGS. 3 to 4, when a person 17 such as a resident, a visitor, or an intruder stands in front of the entrance door 14, the person 17 is placed on the movable body 18 on the upper surface of the pouch 15. At this time, the load and vibration of the person 17 are transmitted through the movable body 18 and reach the vibration detecting device 13. At that time, the sponge 6 and the aluminum rod 8 as vibration transmission promoting means have the following actions. Although the sponge 6 is distorted by the load and vibration, the aluminum round bar 8 is not distorted at the body weight of the person 17, so the piezoelectric sensor 7 is formed on the sponge 6 together with the aluminum round bar 8. It becomes a form to intrude. The piezoelectric sensor 7 is bent along the cross-sectional shape of the aluminum round bar 8 to generate a large signal output. In the experiment, a satisfactory result could be obtained by using a piezoelectric sensor having a diameter of about 2.5 mm and arranging a plurality of aluminum round bars having a diameter of 6 mm at intervals of 50 to 100 mm.

  In addition, when unevenness is provided on the piezoelectric sensor 7 side of the movable body 18, the same effect can be obtained without installing the aluminum round bar 8.

  In addition, since the piezoelectric sensor 7 has flexibility and the aluminum round bar 8 is separated into a plurality, the vibration detector 13 can be bent or rounded in a direction perpendicular to the aluminum round bar 8. There is also an effect that carrying in and installation become easy.

  At this time, the hardness of the sponge 6 is preferably such that when the person 17 is placed on the movable body 18 of the pouch 15, there is no sense of incongruity due to the change, and the displacement is several mm, preferably about 2 mm.

  In this configuration, the vibration detection device 13 may be arranged upside down.

Moreover, although the aluminum round bar 8 was used as a hard rod-shaped member, the same effect can be expected with other metals having a hardness that does not compressively deform due to the weight or vibration of the person 17 or a resin rod. Further, the shape is not limited to a round cross section, and may be an oval shape, an elliptical shape, or a polygonal shape. In the case of a polygonal shape, it is desirable that the corner portion is chamfered so as not to damage the piezoelectric sensor 7. In addition, the diameter and the arrangement interval of the aluminum round bars 7 are only one example, and the effects of the invention are not limited thereto.
Hereinafter, the piezoelectric sensor 7 used in the vibration detection device 13 of the present invention will be described.

  In FIG. 5, the piezoelectric sensor 7 includes a central electrode 701 made of a conductor as an inner electrode, a piezoelectric layer 702 that is a pressure-sensitive member, an outer electrode 703 made of a conductor, and a coating layer 704 made of an elastic body. As the piezoelectric layer 702, a resin-based polymer piezoelectric material such as polyvinylidene fluoride or a composite piezoelectric material in which a piezoelectric resin powder is mixed in a specific resin base material can be used. The outer electrode 703 is disposed so as to surround the inner electrode 701 and the piezoelectric layer 702. Since the piezoelectric sensor 7 has a coaxial cable shape, the outer electrode 703 serves as a shield with respect to the central electrode 701 that transmits a signal. It will be less susceptible to the effects of external electromagnetic noise. Therefore, even when an electronic device is used nearby to collect and process vibration signals or a communication device such as a mobile phone is used nearby, the piezoelectric sensor 7 is less likely to be superposed of noise. A high vibration detection device 13 can be provided.

  Although the coaxial cable-like piezoelectric sensor 7 is shown as an example of the cable-like vibration detecting means having the inner electrode and the outer electrode, the present invention is not limited to this, and a cable having a plurality of center conductors, a center conductor The same effect can be obtained by using a cable that is eccentric from the center of the outer electrode, a cable whose cross-sectional shape is not circular, or the like.

Next, an example of processing of the output signal of the piezoelectric sensor 7 and the detection action of the person 17 will be described. FIG. 6 is a block diagram of the biological signal detection apparatus 10 according to the first embodiment of the present invention. In FIG. 6, the control unit 11 includes a determination unit 21 and a notification unit 22. The judging means 21 filters the output signal from the piezoelectric sensor 7 with a predetermined filtering characteristic and amplifies the output signal with a predetermined amplification degree. The output signal of the filter section 23 is set to a preset value. A comparator unit 24 that performs comparison and a processing unit 25 that receives an output of the comparator unit 24 and discriminates a person and an object based on a predetermined reference and outputs a signal. And the alerting | reporting means 22 receives the output of the process part 25, and outputs a signal so that the visit of the person 17 may be displayed on the display means 16 installed indoors.

  Note that the notification means 22 may output the signal by wire or wirelessly.

  The operation and action of the vibration detection apparatus 13 configured as described above will be described below with reference to FIGS. In FIG. 7, the output signal V of the filter unit 23 corresponding to the output of the piezoelectric sensor 7 when the person 17 rides on the vibration detection means 13 and the vibration of the body of the person 17 is applied to the piezoelectric sensor 7 and the comparator 24 FIG. 6 is a characteristic diagram showing a change with time of an output signal J. FIG. 8 shows the time lapse of the output signal V of the filter unit 23 and the output signal J of the comparator unit 24 corresponding to the output of the piezoelectric sensor 7 when the object is placed on the vibration detecting means 13 and applied to the load piezoelectric sensor 7 of the object. It is a characteristic view which shows a change.

  Here, as the filtering characteristics of the filter unit 23, for example, commercial power supply frequencies that are easily superimposed on a signal as noise are 50 Hz and 60 Hz. As a characteristic, for example, a band-pass filter that passes a signal component of 1 Hz to 20 Hz is used.

Even when the person 17 is in front of the entrance door 14, the person 17 often moves in some way. Also, even if the person 17 is intentionally stopped, the center of gravity is upset and the person 17 stands when standing on the porch 15 in front of the entrance door 14. The vibration such as the load movement and the gravity center fluctuation is applied to the piezoelectric sensor 7 through the movable body 18 of the pouch 15. At this time, the piezoelectric sensor 7 is deformed, and a signal corresponding to the deformation acceleration of the piezoelectric sensor 7 is output by the piezoelectric effect. For this reason, pressure or the like due to body weight without variation is not detected, and only vibration components with variation are detected, and body movement such as shaking is detected. At this time, the bending deformation of the piezoelectric sensor 1 is increased particularly in the portion of the aluminum round bar 8, and a larger output signal is obtained. FIG. 7 shows the output signal V of the filter unit 23. When the person 17 is detected, a signal component larger than the reference potential V ₀ appears in V. And the acceleration which is the secondary differential value of the deformation amount also increases, and as a result, the output signal of the piezoelectric sensor also increases. The comparator unit 24 is amplitude from _{V 0} which _V | V-V ₀ | is determined to detect a vibration, if larger than _{D 0,} and outputs the BALS signal of Lo → Hi → Lo as judging output at time t1.

  This pulse signal appears repeatedly many times while the person 17 is on the pouch 15. On the other hand, as shown in FIG. 8, when an object such as a baggage is placed on the pouch 15, a signal is generated only at the moment when the baggage is placed, but since the baggage itself does not generate vibration, the vibration converges after time Δt. After that, no signal is generated. That is, if a signal derived from vibration is detected continuously for a time Δt or more, it can be determined that the person 17 is in front of the entrance door 14, and the person 17 can be distinguished from an object. Δt is about several seconds, for example, even if the baggage is put slowly, it is considered to be about 10 seconds, and the processing unit 25 determines that the person 17 is detected and outputs a signal when vibration is detected for 10 seconds or more. Then, from this output result, the notification means 22 sends a signal to, for example, the indoor display means 16.

  However, the determination time for a person and a bag is not limited to 10 seconds, and may be set as appropriate according to the installation location and situation.

  As described above, according to the configuration of the present invention, it is possible to reliably discriminate between a person and an object.Therefore, when there is an object in front of the door and there is no person, the door is mistakenly unlocked, or a visitor or a suspicious person It is possible to provide a highly reliable vibration detection device 13 that does not misreport that it has come.

In addition, a small vibration signal due to an object that is obviously lighter than a person, or a large vibration signal that is obviously due to an object heavier than a person may be determined as an object before the determination time elapses by setting a threshold value for the output from the comparator unit 24. good.

  In addition, although the example using the two resin films 9a and 9b as the dustproof and waterproof means has been described, the present invention is not limited to this, and the mouth may be sealed in a single resin bag.

  Note that the installation location of the vibration detection device 13 is not limited to the front door 14 as in the present embodiment, but is installed in front of a doorway door or in front of a window for entering a terrace or a veranda. But there are similar effects.

  In addition, it may be installed in front of a window that normally does not allow people to enter and exit. In this case, it can be used for detecting that a suspicious person is trying to enter the interior of the house. In that case, the notification means 22 may notify the resident's mobile phone or security company that a suspicious person has been detected.

  In addition, even if an airbag is used as an elastic member such as the sponge 6, the same effect can be obtained.

  Further, it is preferable that the pouch 15 has a hole for drainage when water enters the inside.

(Embodiment 2)
A biological signal detection apparatus according to the second embodiment of the present invention will be described with reference to FIG. FIG. 9 is a side cross-sectional view of the vibration detection apparatus of the present embodiment.

  In the following, the second to ninth embodiments will be described only with respect to the points different from the previously described embodiments, and those with the same reference numerals will exhibit the same operational effects and will not be described in detail. .

  The difference of this embodiment from the first embodiment is that it has a sponge 6 and a resin film 9c having no water permeability as a dustproof and waterproof means of the vibration detecting device 13, and the four sides around the resin film 9c and the sponge 6 Is that the piezoelectric sensor 7 is protected against dust and water. In this case, it is desirable to use a closed-cell sponge so that the sponge 6 does not have water permeability. An elastic body such as rubber that is not foamed may be used.

  With the above configuration, the number of component parts can be reduced. Further, since the film member on the lower surface is reduced as compared with the first embodiment, the flexibility is higher and the installation property is better.

(Embodiment 3)

  The difference from the first and second embodiments is that a piezoelectric sensor 7 is attached to the vibration detecting device 13 on the sponge 6 and a flexible and waterproof material such as a silicone sealant 26 is provided thereon. It is the point which apply | coated and laminated | stacked the member.

  At this time, the silicon sealant 26 may be laminated only in the vicinity of the cable-shaped piezoelectric sensor 7. In this case, the arrangement shape of the silicon sealant 26 is meandering like the piezoelectric sensor 7 as shown in FIG. become.

  With the above configuration, the number of component parts can be reduced. Moreover, since the film member on the lower surface is reduced as compared with the first embodiment, and the amount of the upper surface member is small depending on the way of lamination, the flexibility becomes higher and the installation property is improved.

  The silicon sealant 16 may be laminated on the entire surface or may be laminated on the lower surface to further enhance the dustproof and waterproof effect.

  Alternatively, the silicon sealant 26 may be laminated and applied to the piezoelectric sensor 7 in advance and attached to the sponge 6.

FIG. 12A is a side cross-sectional view of the vibration detection device of the present embodiment, and FIG. 12B is a side cross-sectional view showing a state where a load is applied to the vibration detection device of the present embodiment.
The difference from the first to third embodiments is that the vibration detector 13 includes a plurality of aluminum round bars 8 as the first plurality of rod-shaped members and a plurality of aluminum round bars 27 as the second plurality of rod-shaped members. Thus, the first aluminum round bar 8 and the second aluminum round bar 27 are arranged so as not to overlap with each other in that the piezoelectric sensor 7 is sandwiched between the first aluminum round bar 8 and the second aluminum round bar 27. In this example, the aluminum round bar 8 and the aluminum round bar 27 are arranged in parallel to each other, and the aluminum round bar 8 is arranged between the aluminum round bars 27.

  At this time, the piezoelectric sensor 7 sandwiched between the first aluminum bar 8 and the second aluminum bar 27 follows the cross-sectional shape of the aluminum round bar 8 and the aluminum round bar 27 due to a load or vibration from the human body 17. A large signal output is generated due to the bending action. Further, even when the vibration detector 13 is used on the back side, the bending action is applied along the cross-sectional shapes of the aluminum round bar 27 and the aluminum round bar 8 to generate a large signal output. It can be set as the easy-to-use vibration detection device 13 that can be installed in the vehicle.

  Here, the second aluminum rod 27 is arranged at an intermediate position between the adjacent first aluminum round rods 8. By doing so, the first aluminum circle adjacent to the right side of the aluminum round rod 27 is secondly arranged. Since the bending action is generated in the piezoelectric sensor 7 both between the bar 8 and the first aluminum round bar 8 adjacent on the left side, vibration can be detected efficiently.

  Note that the second aluminum round bar 27 is not limited to this, and even if the second aluminum round bar 27 is arranged at a position shifted from the intermediate position of the adjacent first aluminum round bar 8, there is a slight decrease in efficiency. Is detectable.

  In addition, the first plurality of bar members and the second plurality of bar members are not limited to round bars. An elliptical shape, an elliptical shape, or a rectangular shape may be used. In the case of a rectangular shape, it is desirable that corner portions are chamfered so as not to damage the piezoelectric sensor 1. Furthermore, it goes without saying that the same effect can be expected even if the shapes of the first rod-shaped member and the second rod-shaped member are different.

(Embodiment 5)
A vibration detection apparatus according to a fifth embodiment of the present invention will be described with reference to FIGS. 13a and 13b. FIG. 13a is a side sectional view of a pouch in which the vibration detecting device of the present embodiment is embedded, and FIG. 13b is a side sectional view showing a state where a load is applied.

  The difference from the first to fourth embodiments is that the lid 28 is provided on the upper surface of the pouch 15 as a configuration that is installed on the vibration detection device 13 and transmits the vibration to the vibration detection device 13. Thus, the vibration is transmitted to the vibration detecting means 13.

  In FIG. 13 a, the pouch 15 has a lid body 28 that bends in a vertical direction at a part of the upper surface, particularly a part where a person 17 stands, and the vibration detection device 13 is arranged below the vibration body 18 and applied to the movable body 18. Is applied to the vibration detector 13. A packing 29 is disposed in the gap between the main body 19 and the lid body 28 of the pouch 15 so that dust or water enters the inside and the vibration detection device 13 does not get dust or water.

  When there is no person or object on the pouch 15 as shown in FIG. 13a, the lid 28 is not bent, so the vibration detecting device 13 and the lid 28 are not in contact with each other. When the person 17 is placed on the cover 28, the cover 28 is structured to be supported by the pouch 15 around the periphery, so that the central portion of the cover 28 is bent and can contact the vibration detection device 13 to transmit a load or vibration. It becomes like this. At this time, the bending deformation amount of the lid body 28 is preferably set to a hardness or a form so that when the person 17 is placed on the lid body 28, there is no sense of incongruity due to the change, and the displacement is several mm, preferably about 2 mm. .

  Here, since the periphery of the lid 28 is supported, even if the lid 28 is bent, a step is hardly formed at the boundary with the pouch 15, so that a person or an object is not caught and the installation is more natural. The state can be realized.

(Embodiment 6)
A vibration detection apparatus according to the sixth embodiment of the present invention will be described with reference to FIG. FIG. 14 is a side cross-sectional view showing a state in which a load is applied to the pouch in which the vibration detection device according to the present embodiment is embedded. The difference from the first to fifth embodiments is that the movable body 30 of the pouch 15 is not a part of the upper surface of the pouch 15 but the entire upper surface.

  The movable body 30 is supported by a spring 31 so that when there is no person or object, the vibration detection device 13 is not subjected to a load. When a person gets on the movable body 30, it is several mm, preferably about 2 mm. A spring 31 having such a hardness as to be displaced is used. Further, a stopper 32 is provided in the vicinity of the vibration detector 13 installation portion of the main body 19 of the pouch 15. When an excessive load is applied on the movable body 30, the load is received by the stopper 32 and the excessive load is detected by vibration. The configuration is such that the apparatus 13 is not applied. The stopper 32 may be provided on the movable body side or in the vibration detection device 13.

  By adopting such a configuration, it becomes difficult for water or the like poured from above such as rain to enter. Moreover, even if the conductor 30 is displaced, no step is generated in the pouch 15, so that a person or an object is not caught and a more natural installation state can be realized.

  Further, when there is no person or object on the pouch 15, no vibration is applied to the vibration detection means 13, and when an excessive load is applied to the pouch 15, vibration is not applied to the vibration detection means 13. The deterioration with time of the detection means 13 can be suppressed, and a highly reliable product can be obtained.

  Further, it is preferable to provide a damper for damping the vibration so as not to continue to vibrate at the resonance frequency of the spring 31 when a load or vibration is applied to the movable body 30.

In the first to sixth embodiments, the cable-shaped piezoelectric sensor is used as the vibration detecting means. However, other types of piezoelectric sensors may be used. For example, the vibration detecting means may be a film or ribbon having both PVDF thin films sandwiched between electrodes. The same effect can be obtained by using this piezoelectric sensor. However, countermeasures against electromagnetic noise such as wrapping and shielding the sensor itself with a conductive sheet are taken as appropriate. In the first to sixth embodiments, the piezoelectric sensor 8 is used as the vibration detection means. However, the vibration detection means uses an optical fiber having a characteristic that the transmitted light is modulated in response to the pressure deformation. Has the same effect.

(Embodiment 7)
A vibration detection apparatus according to a seventh embodiment of the present invention will be described with reference to FIGS. 15 is a side cross-sectional view of the vibration detection device of the present embodiment, FIG. 16 is a plan view of the entrance / exit, FIG. 17 is a plan view without a movable body of the entrance / exit, and FIG. 18 is a side cross-sectional view of the installation portion of the vibration detection device. FIG. The difference from the first to sixth embodiments is that a hard bar-like member such as an aluminum round bar 8 for promoting the transmission of vibration to the vibration detector is not used. As an alternative to this, a configuration using a deck pullout which is a house entrance / exit member installed on the entrance porch will be described.

  As shown in FIG. 15, the vibration detection device 33 of this embodiment is not provided with the aluminum round bar 8, and the piezoelectric sensor 7 is attached to the surface of an elastic member such as the sponge 6. The sponge 6 and the piezoelectric sensor 7 are covered with two resin films 9a and 9b having no water permeability so as to cover the sponge 6 and the piezoelectric sensor 7 and sealed by thermally welding the four surrounding sides. However, the movable deck 34, which is a movable body disposed thereon, has a large drawing 35 made of aluminum square material or the like on the lower surface, and the vibration detecting device 33 is disposed below the large drawing 35 to move the movable body. The vibration of the movable deck 34 is transmitted to the vibration detection device 33.

  As shown in FIGS. 16 and 17, a large draw 35 is assembled on a pouch main body 19 made of concrete, mortar, or the like, and a plate material such as a wooden board 36 is fixed to be a deck 37 so as to go straight thereon. At this time, for example, the large pull 35 is formed by assembling several tens of millimeters of aluminum square or the like at intervals of several hundred mm, and a wooden board 36 having a width of about 100 mm and a length of about 1 to 2 meters is fixed to the large pull 35. At this time, a part of this deck 37, in particular, the other deck 37 in front of the entrance door 14 is separated and used as the movable deck 34. In order to move the movable deck 34 in the vertical direction, the large pull 35 and the wood board 36 are separated from the other decks 37. In this example, the five wooden boards in front of the entrance door 14 and the large drawer arranged on the lower surface thereof can be separated from the other decks and removed as shown in FIG. The vibration detection device 33 of this example has such a positional relationship and size that it is disposed under the two large forks 35 as shown in FIG. Further, a rubber plate 38 is laid on the lower surface of the vibration detection device 35, and the vibration detection device 33 is damaged by minute protrusions on the concrete surface or mortar surface of the pouch 15, for example, the resin films 9a and 9b for dustproof and waterproof are damaged. Prevents the intrusion of dust and water by improving the reliability. Further, a rubber plate 39 is also laid on the upper surface of the vibration detection device 33 to prevent the vibration detection device 33 from being damaged by a corner portion of the large cross-section 35 and, for example, disconnection of the piezoelectric sensor 7, thereby improving reliability. .

  The place where the rubber plate 38 is installed is not limited to the lower surface of the vibration detection device 33. If there is a concrete surface in the vicinity of the side surface of the vibration detection device 33, it is preferable to install a rubber plate on the side surface. Further, the material of the rubber plate 38 is not limited to rubber, and a resin plate, sponge, or the like can be used so that the protrusion on the concrete surface does not directly contact the vibration detecting device 33.

  The material of the rubber plate 39 between the large pull 35 and the vibration detection device 33 may be not only rubber but also sponge or the like.

  The operation and action of the vibration detection device 33 configured as described above will be described. As shown in FIG. 18, when a person 17 is placed on the movable deck 34, vibration due to the load and movement reaches the vibration detection device 33 through the wooden board 36 and the large pull 35. Then, the piezoelectric sensor 7 is indented into the sponge 6 together with the large pull 35 in the sponge 6 that is deformed by a load or vibration. Since the piezoelectric sensor 7 is subjected to a bending action along the large cross-sectional shape and generates a large signal output, it can reliably detect vibration. Moreover, since the building material generally used for a house is utilized as a vibration transmission promotion member, the structure of the vibration detector 33 can be simplified.

  Although the example in which the wood board 36 is used as the board material of the deck 37 is shown, the present invention is not limited to this, and the same effect can be obtained by using a metal board such as aluminum, a resin board, and a recycled wood board. .

  In addition, as shown in FIG. 19, when there is no large pull in front of the entrance door 14 to be detected, or when the number of large pulls on the vibration detection device 33 is small, a pressing member 40 is arranged as an alternative to the large pull 35. May be. In that case, as shown in FIG. 19, the same effect as the large drawing 35 can be obtained by fixing a member having the same size as the large drawing 35 to the wood block 36 of the movable deck 34 with a screw or the like. However, if the height dimension of the pressing member 40 is not the same as that of the draw 35, the movable deck 34 is inclined, but the width is not necessarily the same. Further, the pressing member 40 is not necessarily installed in parallel with the large drawing 35, and may be installed in a right angle direction. By fixing the pressing member 40 to the movable deck 34, the pressing member 40 can be handled integrally with the movable deck, so that workability is improved.

  In addition, since the number of the large pulls 35 is small, when the overload is locally applied to the vibration detection device 33 and the piezoelectric sensor 7 is crushed, for example, when the weight of the wooden board 36 of the deck 37 is large, the large pulls are performed. By disposing one to several pressing members 40 between 35 and dispersing the pressure, the reliability can be improved.

  As shown in FIG. 20, when the overload 35 is narrow and as a result, an overload is locally applied to the vibration detecting device 33, a hard plate is interposed between the large pull 35 and the vibration detecting device 33. The reliability can be improved by widening the pressure receiving surface and dispersing the pressure by disposing the shaped member, for example, a metal plate 41 having a thickness of several millimeters with a width larger than the large width. The metal plate is preferably made of aluminum or stainless steel which is not easily corroded, but is not limited to this, and other metals or strong resin may be used.

  Moreover, although the movable deck 34 can be removed, if the jig | tool 42 like FIG. 21 is used, workability | operativity will improve. The jig 42 has a U-shape, and includes a main body 43 having a diameter of about 10 mm and a grip portion 44. The gap between the wooden boards 36 constituting the movable deck 34 is small so as not to impair the aesthetics or to allow an object to fall down, and is not necessarily enough to allow the operator's hand to enter. Therefore, as shown in FIG. 22, the end of the U-shaped jig 42 is put in the gap of the wooden board 36 and hooked, and the operator can hold the grip portion 44 and lift it at both ends of the movable deck 34. Thereby, since it is not necessary to make a big hole for putting a hand in the deck 37 in order to maintain the vibration detection apparatus 33, workability | operativity can be improved without impairing aesthetics.

  The elastic body on which the piezoelectric sensor 7 is attached is not limited to a sponge, but may be non-foamed rubber. In this case, the same effect is obtained that the piezoelectric sensor 7 emits a signal when the piezoelectric sensor 7 enters the rubber due to the elasticity of the rubber. Alternatively, a non-foamed rubber and sponge may be stacked. In addition, the piezoelectric sensor 7 may be attached to a cloth or a film without being attached directly to an elastic body such as the sponge 6 and enclosed in the resin films 9 a and 9 b together with the sponge 6.

(Embodiment 8)
A vibration detection apparatus 13 according to an eighth embodiment of the present invention will be described with reference to FIG. FIG. 23a) is a side sectional view showing a state where no load is applied to the pouch 15 in which the vibration detection device 13 of the present embodiment is embedded, and FIG. 23b) is a pouch in which the vibration detection device 13 of the present embodiment is embedded. FIG. 15 is a side sectional view showing a state in which a load is applied to 15. The difference from the first to seventh embodiments is that the movable body is divided into a plurality of parts.

  The movable body of the present embodiment is divided into two in the longitudinal direction, which are a first movable body 44a and a second movable body 44b. At this time, when the person 17 is placed on the second movable body 44b, a load and vibration are applied only to the first movable body 44b, and the vibration detecting device 13 only in a portion below the second movable body 44b receives a deformation action and receives a signal. Is output. Since the piezoelectric sensor 7 generates a signal even with a partial deformation action, the vibration detection device 13 can detect the person 17.

  With such a configuration, the mass of each of the movable bodies 44a and 44b can be reduced, so that the movable bodies 44a and 44b can be moved even with a smaller force, and smaller vibrations can be detected. Can be increased. Moreover, since the mass of the movable bodies 44a and 44b is small, the movable bodies 44a and 44b can be easily lifted during maintenance, so that workability is improved.

  Moreover, as shown in FIG. 24, the pressing member 46 may be arranged on the lower surface of each of the movable bodies 45a and 45b divided into a plurality. For example, an aluminum square bar of about several tens of millimeters is used as the pressing member 46, and about 2 to 3 pieces are installed under the movable bodies 45a and 45b. With such a configuration, the load and vibration applied to the movable bodies 45a and 45b are concentrated on the pressing member 46 and transmitted to the vibration detecting device 33. Therefore, the pressing member 46 becomes a vibration transmission promoting member, As in the seventh embodiment, the vibration detecting device 33 having a simpler configuration without the aluminum round bar 8 can be obtained.

  In addition, although the structure which divides | segments a movable body into 2 was demonstrated in this Embodiment, it is not restricted to this, Even if it divides | segments into 3 or more, there exists the same effect. The same applies to the case of division in the depth direction of FIG. 23 and FIG. 24, and further, it may be divided in the longitudinal direction and also in the depth direction as shown in FIG.

  In addition, the planar shape of the divided movable body 28 may be a polygon or a circle instead of a rectangle. For example, if it is a hexagon like a beehive, a movable body can be arranged without a gap. In this way, each of the divided movable bodies may be configured so that it can move independently when it receives a load. If it is not a proper shape, the size and shape of the divided movable body may be adapted to the situation in the field and the properties of the members.

(Embodiment 9)
A vibration detection apparatus according to the ninth embodiment of the present invention will be described with reference to FIGS. FIG. 26 is a block diagram when the vibration detection device is used as a security device, and FIG. 27 is a configuration diagram of the entrance where the vibration detection device is installed. The difference from the first to sixth embodiments, especially the difference from the first embodiment, is that the operation after the vibration detection device detects vibration is used to determine the suspicious person and to deal with the suspicious person. It is a point.

The processing of the output signal of the vibration detection device 13 will be described below. In FIG. 26, when the control unit 11 detects a vibration signal, the control unit 11 sends a signal to the controller 47 which is a determination unit coupled by wire or wirelessly. Then, the controller 47 that has received the signal performs wireless communication with an ID card 48 that is an ID transmitter / receiver of a person permitted to enter the room. The person permitted to enter the room is, for example, a resident or a visitor. At this time, when the ID registered in advance can be verified, an operation such as unlocking the entrance door 14 is performed. If the ID cannot be verified, or there is no ID card, the controller 47 determines that the person is a suspicious person or an unconfirmed person, and displays a signal indicating that the unidentified person has visited or there is a suspicious person on the display means 16 installed indoors. Is output. At the same time, the camera 49, the light 50, the speaker 51 and the like installed outdoors are operated. As shown in FIG. 27, outside the house, a lighting device such as a camera 49 and a light 50, a speaker 51, and the like are installed toward the entrance door 14 where the vibration detection device 13 is installed. When a suspicious person is detected, the light 50 directed toward the vibration detection device 13 illuminates the suspicious person, and the camera 49 captures and records the suspicious person's figure and face. Further, a warning sound is emitted from the speaker 51 and threatened. The light 50 may be used not only for the purpose of illumination for the camera 49 but also for the threat of a suspicious person. By doing so, the intrusion of suspicious persons can be prevented and recorded.

  Further, in the configuration as in the conventional example, since the electrodes are in contact with each other to generate a signal, detection cannot be performed until a predetermined displacement occurs in the detection device, but the piezoelectric sensor 7 generates an output to detect the deformation acceleration. The time until the response time is as fast as several tens to several hundreds of ms after applying a load or vibration regardless of the displacement, so devices such as the camera 49 and the light 50 are activated before the suspicious person moves. Therefore, the detected suspicious person can be photographed reliably.

  In this example, the configuration in which the vibration detection device 13 is installed in front of the entrance door 14 has been described. However, the present invention is not limited to this, and the same is true even if it is installed in a place where a suspicious person may enter such as in front of a door or under a window. The following effects can be obtained. Moreover, if it installs in more places, such as under the entrance door 14, a doorway, and a window, the comprehensive security performance of a house will become severer.

  It should be noted that the camera 49 and the light 50 are not only the entrance door 14 where the vibration detection device 13 is installed, but also can capture and illuminate a wider area around the entrance door 14, so that the suspicious movement is quick. A person or a suspicious person who escaped suddenly is more likely to be photographed in any part of the field of view of the camera 49, and is preferable because it can be photographed without missing. Further, by photographing and illuminating a wide range, it is possible to reduce the possibility that a suspicious person will be missed when there are multiple suspicious persons.

  If the light 50 is installed at the same position and in the same direction as the camera 49, it can be expected that the light 50 will not be backlit when photographing a suspicious person.

  The camera 49 may be a still image shooting camera or a moving image shooting camera, or may be a high-sensitivity camera in case of darkness such as at night or for installation in a shaded place. In this case, since illumination for photographing is not always necessary, the light 50 does not have to coincide with the photographing range of the camera 49, and for example, a position that blinds the suspicious person effectively. Or it may be oriented. Further, the lighting device such as the light 50 may use a flash or the like. Furthermore, not only voice notification and threatening by the speaker 51, but also the generation of threatening sound by a buzzer may be used.

  As described above, since the vibration detection device according to the present invention has waterproof and dustproof means arranged in the vibration detection means, it is embedded not only around the house but also around the fence laid on the site of factories, railways, airports, etc. For example, it can be used as a security system such as installing in front of a plurality of lockers or room doors and reporting when the door is illegally opened.
