Description

Oscillation detection device

The present invention relates to a vibration detection device.

Conventionally, a sensor that converts the pressure applied to an object into an electrical signal and outputs it is known. For example, Patent Document 1 discloses a vibration detection device used for a window-proof security device, which converts a pressure applied by a piezoelectric element into a voltage, amplifies the voltage by an amplifying circuit, and generates a vibration noise component. There is attenuation by the filter circuit.

According to such a vibration detection device, a change in external force can be detected as a simple change in voltage value. For example, when mounted on a glass plate, the vibration of the vibration is attenuated, so that malfunction due to vibration is prevented, It can be detected as an abnormality when vibration by breakdown, a strike, etc. is more than a threshold value.

[Patent Document 1] Patent No. 2620211 (paragraphs 0008 to 0011)

However, since the magnitude of the voltage of the piezoelectric element is proportional only to the "magnitude" of the vibration and is not related to the type (shock, deformation, etc.), as described above, simply converting the external force into a voltage provides a vibration detection device. Although it was possible to detect that a certain amount of external force was applied to the attached object, it was not possible to distinguish what thought the external force was caused by.

Therefore, when a threshold value is set on the basis of a relatively small magnitude of vibration caused by the opening and closing of a window, there is a possibility that the small impact generated when the glass is lightly knocked is detected as abnormal. In addition, if the threshold value is set based on the magnitude of the relatively large vibration due to window breakage or the like, there is a fear that a small vibration such as opening and closing of the window cannot be detected as an abnormality.

The present invention proposes a vibration detection device capable of discriminating what kind of external force is caused by an action when an external force is applied from the background.

In order to solve the above problems, the vibration detecting apparatus according to the present invention comprises a detector for converting the pressure change applied to the object into a voltage, and a measurement unit for measuring the voltage output from the detection unit, the measurement unit And a filter means for respectively passing the voltages outputted from the plurality of frequency bands, and outputting voltages of the plurality of frequency bands passed through the filter means as respective signals.

The detection unit and the measurement unit are mounted on the same circuit board.

The detection unit and the measurement unit are mounted on the same circuit board, and the circuit board is covered in a case.

The detection unit is characterized in that it is covered by a coating material and does not directly contact air.

The signal output from the measuring unit includes a first signal indicating that pressure is applied to the object over time, and a second signal indicating that pressure is momentarily applied to the object.

The detection unit may be configured by a unimorph piezoelectric element or a bimorph piezoelectric element.

The measuring unit sets thresholds for voltages in a plurality of frequency bands, and outputs the signals when measuring voltages equal to or greater than the threshold.

When an external force is applied to a detection unit such as a piezoelectric element, the vibration of the detection unit varies according to the type (applied method) of the external force, and the frequency characteristic of the generated voltage changes. For example, when an external force is momentarily applied, such as a strike, an electromotive force having a relatively high frequency is generated. When an external force is applied over time so as to be gradually deformed, an electromotive force having a relatively low frequency is generated.

Therefore, the type of external force can be discriminated by extracting the voltage generated from the piezoelectric element for each frequency band corresponding to the type of external force by using the filter means in the measurement unit. For example, when a high frequency voltage is measured, it can be determined that a hit or the like has been given, and when a low frequency voltage is measured, it can be determined that an external force such as deformation is given. In this way, if a threshold value of a different voltage is set for each frequency band, detection according to the type of external force is possible.

Since the detection unit converts the external force into a voltage, and the voltage is output as a signal for each of a plurality of frequency bands by the measurement unit, an external force corresponding to each frequency (for example, an instantaneous external force or an external force over time) is applied to a certain degree. You can recognize if you are losing.

EMBODIMENT OF THE INVENTION Hereinafter, with reference to drawings, the best form for implementing this invention is demonstrated. For convenience, unless otherwise indicated, parts showing the same effect are denoted by the same reference symbols, and description thereof is omitted.

FIG. 1A shows a plan view of the detection unit 20 in the vibration detection device 1, and FIG. 1B shows a side view. The piezoelectric element 10 used in the vibration detecting device 1 is a unimorph piezoelectric element, and electrodes 10b and 10c are formed on both surfaces of the piezoelectric ceramic 10a such as barium titanate, lead titanate, and lead zirconate titanate. In the present embodiment, the piezoelectric ceramic 10a has a disk shape of about 9 mm in diameter and about 0.1 mm in thickness, and the electrodes 10b and 10c are circular with a diameter of about 8 mm. One side (electrode 10c side) of the piezoelectric element 10 is bonded to a metal plate 12 such as brass, stainless steel, etc., whereby a detection unit 20 for detecting vibration is provided. In this embodiment, the metal plate 12 is circular with a diameter of about 12 mm and has a thickness of about 0.1 mm.

The detection unit 20 is formed when the metal plate 12 is bent in the direction shown in FIG. 2A and the piezoelectric element 10 is stretched in the radial direction, and the metal plate 12 is shown in FIG. 2B. Since the direction in which the voltage generated when the piezoelectric element 10 is reduced by bending is reversed, the detection unit 20 vibrates so that the bending of the metal plate 12 alternates the state of (a) and the state of (b). Repeatedly generates AC voltage of frequency according to vibration. Therefore, by measuring the voltage generated by the detection unit 20, it is possible to determine how the detection unit 20 is vibrating.

The detection unit 20 is bonded to a circuit board 14 such as a glass epoxy substrate on the metal plate 12 side (see FIG. 4). The circuit board 14 includes a filter circuit 22 for cutting the noise component from the voltage generated by the detector 20, an amplifier circuit 24 for amplifying the voltage passing through the filter circuit 22, and the amplifier circuit ( A measuring section 30 for measuring the voltage amplified by 24) and an output connector 28 for outputting the measurement result from the measuring section 30 are provided (see Fig. 3). As such, the detection unit 20, the filter circuit 22, the amplifier circuit 24, and the measurement unit 30 are integrally provided on the same circuit board 14, so that the noise due to the wiring and the like is reduced and high precision sensing is performed. can do. Moreover, it becomes a compact vibration detection apparatus and unitization becomes easy. In addition, since the detection unit 20 is mounted on the circuit board 14, when the vibration detection device 1 is mounted on an object to be sensed, the inherent vibration of the object is caused by inherent vibration rather than mounting the detection unit 20 directly to the object. It is difficult to be affected.

Lead wires (not shown) are respectively attached to the electrode 10b and the metal plate 12 on the surface side of the detection unit 20, and the lead wires are connected to be input to the filter circuit 22. The adhesion of the detection part 20 can suppress that vibration is absorbed by an adhesive agent by using the thing with the high hardness after adhesion | attachment like an epoxy adhesive agent. In addition, when mounting the detection unit 20, the filter circuit 22, the amplifier circuit 24, and the measurement unit 30 on the circuit board 14, other circuits or the like within 2 mm of the detection unit 20 (filter circuit ( 22), it is preferable not to arrange the amplification circuit 24 and the measurement part 30. This is to prevent unnecessary noise from being generated by disposing other circuits or the like.

The filter circuit 22 cuts the frequency components (noise) that are not necessary for measurement, and filters the frequency components necessary for the measurement. In this embodiment, it consists of a high pass filter and a low pass filter, and cuts out the components which are not necessary for a measurement from the voltage which the detection part 20 generated. In addition, the filter circuit 22 is comprised by a capacitor | condenser and a resistor, for example.

The voltage amplification ratio of the amplification circuit 24 can be appropriately changed, and when the voltage generated by the detection unit 20 is high depending on the installation target or the installation position, the voltage amplification ratio is not so large, for example, about 3 to 5 times. When the voltage generated by the detector 20 is low, the voltage amplification factor can be increased to about 20 times, for example. The amplifier circuit 24 is configured using, for example, an operation amplifier and a resistor.

The measurement unit 30 measures voltage values of a plurality of kinds of frequency bands from the input voltage, and determines whether each measured value exceeds a threshold value, and A / A for converting an input analog voltage into a digital voltage signal. The digital filter which is the filter means 34 which filters the voltage signal of the frequency band to be measured from the voltage signal converted by the D conversion means 32 and the A / D conversion means 32, and the voltage which filtered the said digital filter. Comparing means 36 for outputting a comparison result by comparing the signal with a threshold. The measuring unit 30 is, for example, a ROM that stores a program for realizing the functions of the filter means 34 and the comparison means 36, a CPU that executes arithmetic processing based on a program stored in the ROM, and arithmetic processing of the CPU. It consists of a one-chip microcomputer etc. equipped with RAM and A / D conversion function which function as a work area of data in the system.

For example, when measuring two kinds of frequency bands, the voltage of the first frequency band filtered by the first digital filter 34a with respect to the voltage signal inputted to the measuring unit 30 and A / D converted. The signal is monitored by the first comparing means 36a, and the voltage signal of the second frequency band filtered by the second digital filter 34b is monitored by the second comparing means 36b. Then, a signal according to a result of comparing a predetermined threshold value with respect to each voltage signal and each frequency band is output. For example, when a voltage signal equal to or greater than the threshold is measured, a signal indicating such content is output. When a voltage signal equal to or greater than the threshold is not observed, a predetermined signal is output. Therefore, when an irregularity such as disconnection of the output line from the vibration detection device 1 is performed, disconnection or the like can be detected by not being able to receive any signal at the output destination of the vibration detection device 1. have. Moreover, you may make it the structure which always outputs a constant pulse signal irrespective of the comparison result with a threshold value.

5 and 6 show changes in time of the voltage generated by the detection unit 20 when an external force is applied to the vibration detection device 1, respectively. FIG. 5 is a case where an external force is applied (deformation) over time so as to gradually deform, and FIG. 6 is a case where an external force is momentarily applied (tapping) such as a strike. Here, in the case of the modification, a voltage characteristically occurs at a voltage having a frequency band of 0.1 Hz to 10 Hz, in particular 1 Hz to 5 Hz, which is a relatively low frequency. In the case of tapping, a voltage characteristically occurs at a voltage having a frequency band of 10 Hz to 40 Hz, particularly 20 Hz to 40 Hz, which is a relatively high frequency.

Thus, for example, in the case of measuring deformation and tapping, the frequency band filtered by the first digital filter 34a is set to 0.1 Hz to 10 Hz, and the frequency band filtered by the second digital filter 34b is set to 10 Hz to 40 Hz. Can be set to In addition, in order to discriminate deformation and tapping with higher accuracy, the frequency band filtered by the first digital filter 34a is set to 1 Hz to 5 Hz, and the frequency band filtered by the second digital filter 34b is set to 20 Hz to 40 Hz. It is good to set.

In addition, the voltage signal obtained by filtering the first digital filter 34a and the second digital filter 34b is output as it is (or by D / A conversion), respectively, and it is determined whether the threshold value is exceeded by a comparison means provided before the output. Also good. In this case, since a certain voltage such as noise is always output, it is not necessary to always output a constant signal as described above.

Moreover, although the method of installing the filter means 34 in the measurement part 30 was shown, as another method, the voltage generate | occur | produced by the detection part diverges, and the 1st filter circuit (band pass filter) is provided with respect to the other, It is also possible to pass a second filter circuit (band pass filter) to obtain voltages of two kinds of frequency bands, respectively, and to determine whether a threshold is exceeded by providing a comparison means for each.

The circuit board 14 to which the detection unit 20, the filter circuit 22, the amplification circuit 24, and the measurement unit 30 are fixed includes, for example, a box portion 41 in which a plastic or the like is concave, and the box. It is covered with the case 40 which consists of the cover part 45 which couples to the part 41 (refer FIG. 4). Through-holes 14a and 14b are formed in the diagonal corners of the circuit board 14, and the through-holes 14a and 14b of the circuit board 14 are also formed in the box part 41 and the cover part 45, respectively. The through holes 41a, 41b, 45a, 45b are formed in the corresponding portions. The through-holes 41a and 41b on the side of the box portion 41 are drilled to the center of the columnar portions 42a and 42b protruding upward from the bottom of the box portion 41, and penetrate through the lid portion 45 side. The holes 45a and 45b are drilled to the center of the columnar portions 46a and 46b protruding downward from the back surface side of the lid portion 45. As a result, when the circuit board 14 is covered with the case 40, the circuit board 14 includes the columnar portions 42a and 42b of the box portion 41 and the columnar portions 46a and 46b of the lid portion 45. Pinched by In addition, since the through holes 45a, 14a and 41a penetrate through the through holes 45b, 14b and 41b, the case 40 and the circuit board 14 can be fixed diagonally by two screws. have. In the box portion 41, a through hole 47 is formed at a position corresponding to the output connector 28 provided on the circuit board 14. The through hole 47 is blocked by the output connector 28 in a state where the circuit board 14 is accommodated in the box portion 41.

By covering the circuit board 14 with the case 40 in this manner, since the detector 20 is cut off from the outside by the case 40, external air does not affect the detector 20. In addition, when not using the case 40, it is preferable to coat the detection part 20 with epoxy resin etc. in order not to be influenced by air. In addition, the cover may be covered with the case 40, or the epoxy resin or the like may be filled in the state in which the circuit board 14 is stored in the case 40. In this case, the air is also blocked from the air in the case. It is not affected by. In addition, the material for coating and filling can be changed suitably.

The installation of the vibration detecting device 1 covered with the case 40 to the object may be bonded to the case 40 and the object, but is screwed by a through hole formed in the case 40 and the circuit board 14. It is preferable. Vibration or deformation of the object is conducted to the circuit board 14 through the case 40 because the circuit board 14 is pinched by the box portion 41 and the cover part 45. It is directly conducted from the screw to the circuit board 14, so that the accuracy of detection is increased. In addition, since the through holes for screwing are formed on the diagonal, vibration is likely to be transmitted to the circuit board 14.

Although the case of measuring about two types of frequency bands was shown, it is not limited to this, It can measure about three or more types of frequency bands. In this case, for example, it can be realized by increasing the number of digital filters and determining means.

Although the unimorph piezoelectric element was demonstrated as an example as the piezoelectric element 10, it is not limited to this, It is also possible to use a bimorph piezoelectric element. The bimorph piezoelectric element has a structure in which piezoelectric elements are adhered to both surfaces of a metal plate, and similarly to unimorph piezoelectric elements, voltage is output in accordance with a change in external force due to vibration or the like.

The launch unit 292 includes a sensor (not shown) for detecting organic manipulations by an organic person, a solenoid (not shown) for firing organic beads, and the like, to launch organic beads for organic matter. When the bead control board 203 receiving the image detects the organic manipulation by the sensor of the launching unit 292, in response to the detected organic manipulation, the solenoid or the like is driven to intermittently shoot the organic beads, and the organic plaque 101 Organic beads are sent to the organic region 103 of.

The vibration detecting device 1 is sealed in the case 40 and is fixed to a central portion (part indicated by A in FIG. 8) of the plate-shaped iron plate 127 provided on the right and left sides of the frame member 110 across the left and right sides. do. As the vibration detecting device 1 is fixed to the rigid plate-like member which is widely installed in this manner, the vibration generated in the pachinkogi 100 can be easily transmitted to the vibration detecting device 1. The main control board 201 is connected to the output side of the vibration detection device 1, and a process for cheating is performed in accordance with a signal from the vibration detection device 1.

In this embodiment, the vibration detector 1 deforms the frame member 110 so that the intruder intrudes the piano wire or the wire into the organic panel 101 and bends the nails such as bending the nail. By tapping the pachinkogi 100 is to detect the negative (so hard hitting, tapping the device) to change the behavior of the organic beads at the same time. In this case, when an external force such as deformation by wire manipulation is applied over time, a voltage having a frequency band of 0.1 Hz to 10 Hz, particularly a voltage of 1 Hz to 5 Hz, is characteristically generated in the detection unit 20. In addition, when an instantaneous impact such as tapping due to hard hitting is applied, the detection unit 20 characteristically generates a frequency band of 10 Hz to 40 Hz, particularly a voltage of 20 Hz to 40 Hz. In addition, the voltage generated from the detection unit 20 by vibration of the organic beads, vibration of the launching unit, vibration of the variable granular apparatus (opening / closing door 109a), and vibration of the production counterparts 115 and 116 generated when abandonment is performed. Any frequency is characteristic at several kHz.

The filter circuit 22 is comprised by the high pass filter which filters the voltage which has a frequency above 0.1 Hz, and the low pass filter which filters the voltage which has a frequency below 50 Hz. As a result, only the frequency band of 0.1 Hz to 50 Hz, including the frequency band (0.1 Hz to 10 Hz) for detecting deformation and the like from the voltage output from the detector 20 and the frequency band (10 Hz to 40 Hz) for detecting tapping and the like, can be filtered. It is possible to cut other noise components including a voltage generated by vibration of organic beads or the like. In addition, the amplifier circuit 24 is a circuit which amplifies an input voltage about three times. As a result, the voltage from which the noise is removed from the filter circuit 22 is amplified and input to the measurement unit 30.

In the measuring unit 30, the input voltage of the frequency band of 0.1 Hz to 50 Hz is first A / D converted from an analog voltage to a digital voltage signal. Subsequently, a first measurement voltage (0.1 Hz to 10 Hz frequency band) and a voltage signal having a frequency of 10 Hz to 40 Hz through a digital low pass filter, which is a first filter 34a that filters only voltage signals having a frequency of 10 Hz or less. The second measurement voltage (frequency band of 10 Hz to 40 Hz) passing through the digital bandpass filter, which is the second filter 34b that filters the bay, is compared and processed by the first comparing means and the second comparing means, respectively. Further, a digital bandpass filter for filtering a voltage signal in a frequency band of 1 Hz to 5 Hz as the first filter 34a, and a digital bandpass filter for filtering a voltage signal in a frequency band of 20 Hz to 40 Hz as a second filter 34b. When used, the waveform analysis process can be performed with higher accuracy.

The first measurement voltage is compared with or more than a deformation threshold set in advance by the first comparing means 36a, and when it is equal to or more than the deformation threshold, a deformation detection signal indicating such contents is output to the main control board 201. Further, the second measurement voltage is compared with whether or not the tapping threshold set in advance by the second comparing means 36b, and when the tapping threshold is equal to or more than the tapping detection signal, the tapping detection signal indicating the content is output to the main controller 201. In addition, since the voltage generated by deformation or the like due to misconduct is smaller than the voltage generated by tapping or the like, the deformation threshold is set smaller, for example, the deformation threshold is 100 mV and the tapping threshold is 500 mV. In the normal state, the normal detection signal, which is a constant pulse signal, is output from the measurement unit 30. Therefore, when irregularity, such as disconnection of the output line from the vibration detection apparatus 1, is performed, it can detect by not being able to receive a normal detection signal in the main board 201.

The operation example of the vibration detection apparatus 1 is shown. When the operator inserts a driver or the like between the frame member 110 and the outer frame 123 of the pachinko corgi 100, deformation occurs in the frame member 110 (steel plate) on which the vibration detecting device 1 is fixed. As a result, a voltage including a frequency band of 0.1 Hz to 10 Hz, which is a frequency characteristically generated from deformation, is generated from the detection unit 20 in the vibration detection device 1. The voltage is amplified by the filter circuit 22 by a frequency other than 0.1 Hz to 50 Hz and then amplified by about three times by the amplifier circuit 24 and input to the measurement unit 30. The voltage value here is, for example, 100 mV or more at 0.1 Hz to 10 Hz, and 500 mV or less at 10 Hz to 50 Hz.

The voltage input to the measuring unit 30 is converted into a digital voltage signal by the A / D conversion means 32, and a voltage signal of 0.1 Hz to 10 Hz, which is a frequency band of 10 Hz or less, by the digital low pass filter (first measurement Voltage) is extracted. In addition, a voltage signal (second measurement voltage) in the frequency band of 10 Hz to 40 Hz is extracted by the digital band pass filter.

The first measured voltage determines whether the voltage value is 100 mV or more by the first comparing means. In addition, the second measured voltage determines whether the voltage value is 500 mV or more by the second comparing means. Since deformation due to insertion of the driver occurs, the voltage value of 500 mV or more is not measured by the second comparing means, but since the voltage of 100 mV or more is measured by the first measuring means, the strain detection signal is not applied to the main control board 201. Is sent.

In addition, when the organic person hardly hits the pachinkogi 100, the vibration is conducted to the iron plate 127 on which the vibration detecting device 1 is fixed. As a result, a voltage including a frequency band of 10 Hz to 40 Hz, which is a frequency characteristically generated on tapping from the detection unit in the vibration detection device 1, is generated. The voltage is amplified by the filter circuit 22 by a frequency other than 0.1 Hz to 50 Hz and then amplified by about three times by the amplifier circuit 24 and input to the measurement unit 30. The voltage value here is, for example, 500 mV or more at 10 Hz to 40 Hz, and 100 mV or less at 01 Hz to 10 Hz.

The voltage input to the measuring unit 30 is converted into a digital voltage signal by the A / D conversion means 32, and is 0.1 Hz to a frequency band of 10 Hz or less by the digital low pass filter as the first filter means 34a. The voltage signal (first measured voltage) of 10 Hz is extracted. In addition, a voltage signal (second measurement voltage) in the frequency band of 10 Hz to 40 Hz is extracted by the digital band pass filter, which is the second filter means 34b.

The first measured voltage is determined by the first comparing means 36a to determine whether the voltage value is 100 mV or more. In addition, the second measured voltage determines whether the voltage value is 500 mV or more by the second comparing means 36b. Since the vibration is generated by striking the pachinkogi 100 strongly, the voltage value of 100 mV or more is not measured by the first comparing means 36a, but the voltage of 500 mV or more is measured by the second comparing means 36b. The tap detection signal is transmitted to the substrate 201.

The processing by the main control substrate 201 for cheating will be described with reference to FIG. 11. First, the main board 201 detects whether there is an input signal from the vibration detecting device 1 (step S101). When the cheating is not performed from the vibration detecting device 1 to the main control board 201 (when the deformation detection signal and the tapping detection signal are not transmitted), a normal detection signal is output. If no signal is detected from the vibration detecting device 1 in 201, an error detection process is performed and an error message is transmitted to the management device (for example, the hall computer) (step S107). Thereby, confirmation of disconnection etc. by a hall point source becomes possible.

In the case where the signal from the vibration detection device 1 is input, when it is determined that the signal is a normal detection signal, it is detected again whether there is an input signal without performing further processing (step S102). When it is determined that the signal from the vibration detecting device 1 is not a normal detection signal, it is determined next whether it is a deformation detection signal (step S103). If it is determined that the distortion detection signal is present, deformation detection processing is performed (step S104).

According to the deformation detection process, a deformation notification command is sent from the main control board 201 to the sub-control board 202, and the display and voice notification indicating that the door is open with the output of the alarm sound, or the lamp control. It can be notified by the blinking of the directing light 111 by the substrate 206. Thereby, it is possible to inform the officer of the organic field that excessive deformation is applied to the pachinkogi 100, and let the officer go to the pachinkogi 100 to perform the necessary treatment. In addition, when a deformation notification command is sent from the main control board 201 to the bead control board 203 received as an image, the launch stop process is performed to prevent the launch of the organic beads, and the stop payment process is performed to pay the organic beads. This is not done. The main control board 201 may stop the basic operation after transmitting the deformation notification command so that a signal from each detection unit is not input. In this case, if it is set as a structure which recovers | restores by the recovery process by a person in charge, an irregularity will be prevented further.

If it is determined in step S103 that it is not a distortion detection signal, it is determined whether or not it is a tapping detection signal (step S105). If it is determined here that it is a tap detection signal, a tap detection process is performed (step S106).

According to the tapping detection process, a tapping notification command is sent from the main control board 201 to the sub-control board 202, and a display notification of the content instructing not to knock the door with the output of the alarm sound or the lamp control board 206 is performed. It can also be notified by the blinking of the rendering light 111 by. Thereby, it is possible to inform the officer of the organic field that an excessive shock is applied to the pachinkogi 100, and let the officer go to the pachinkogi 100 to perform the necessary treatment. In addition, when a tapping notification command is sent from the main control board 201 to the bead control board 203 received as an image, the launch stop processing is performed so that the launch of the organic beads is not possible, and the stop payment processing is performed to pay the organic beads. This is not done. The main control board 201 may stop the basic operation after transmitting the tapping notification command so that a signal from each detection unit may not be input. In this case, if it is set as a structure which recovers | restores by the recovery process by a person in charge, an irregularity will be prevented further.

In addition, when the process of stopping a part or all of the functions of the organic processes by the strain detecting process and the tapping detecting process is performed, the organic state immediately before the strain detecting signal and the tapping detecting signal is input to the main control substrate 201 is stored. Is preferably. Thereby, when it is judged that it is not cheating by the confirmation of the officer, when an abandonment is restored, it becomes possible to return an abandonment state.

If it is determined in step S105 that it is not the tap detection signal, it is considered that an unknown signal other than the normal detection signal, the deformation detection signal, and the tap detection signal is input. In this case, an error detection process is performed and a management device (for example, a hall An error message is sent to the computer). In this way, failure, malfunction, or the like of the vibration detection device 1 is confirmed by the hall point source. Moreover, although the structure which performs the same error detection process in the case where the signal from the vibration detection apparatus 1 is not input and in the case where an unknown signal is input is shown, you may set it as a separate error process, respectively.

In addition, when the distortion detection signal is outputted, an example in which the pachinkogi is notified by the strain detection process (step S104) has been presented. However, only the pachinko hole management device may be notified without performing this. Unlike the hard hitting, which is the target of the strain detection signal, unlike the hard hitting, which is the target of the tapping detection signal, the operation is more likely to be performed continuously for a long time. Become.

The vibration detection apparatus 1 is screwed to the center part (part shown by B of FIG. 13) of the horizontal frame 1311 provided in the back surface side of the front door 1003 in the state enclosed in the case 40. As shown in FIG. As the vibration detecting device 1 is fixed to the rigid plate-like member which is widely installed in this manner, the vibration generated in the slot machine 1001 can be easily transmitted to the vibration detecting device 1. The main control board 1021 is connected to the output side of the vibration detection device 1, and processes fraudulent acts in accordance with a signal from the vibration detection device 1.

In the present embodiment, the vibration detection device 1 causes the concealer to open the front door 1003 forcibly to operate the medal selector unfairly (an act of fraud) and to strongly strike and damage the slot machine 1001. (Damage behavior) is detected at the same time. In this case, when an external force such as deformation due to cheating is applied over time, a voltage having a frequency band of 0.1 Hz to 10 Hz, particularly a voltage of 1 Hz to 5 Hz, is characteristically generated in the detector 20. In addition, when a momentary impact such as tapping due to a damage action is applied, a voltage having a frequency band of 10 Hz to 40 Hz, particularly a voltage of 20 Hz to 40 Hz, is characteristically generated in the detector 20. In addition, the frequency of the voltage generated from the detection unit 20 due to the vibration of the reel generated when abandoning or the like is characteristically shown at several kHz.

Since the configurations of the filter circuit 22 and the amplifier circuit 24 are the same as those in the first embodiment, they are omitted. In the measurement unit 30, the deformation threshold is 200 mV and the tapping threshold is 800 mV, which is larger than the setting for the pachinkogi 1. In the slot machine 1001, the tapping operation such as tapping the slot button 1014 to stop the reel is performed on a daily basis. When the vibration generated therefrom is disturbed, normal tapping is caused. The threshold is set large. In addition, since the voltage generated when the front door 1003 is forcibly opened is higher than the voltage generated when the frame member 110 of the pachinkogi 1 is deformed, the deformation threshold is set large. Regarding the measurement unit 30, other configurations are omitted because they are the same as in the first embodiment.

The operation example of the vibration detection apparatus 1 is shown. When the owner attempts to open the front door 1003 of the slot machine 1001, deformation occurs in the horizontal frame 1311 in which the vibration detecting device 1 is fixed. As a result, a voltage including a frequency band of 0.1 Hz to 10 Hz, which is a frequency characteristically generated with respect to deformation, is generated from the detection unit in the vibration detecting apparatus 1. The voltage is amplified by the filter circuit 22 by a frequency other than 0.1 Hz to 50 Hz and then amplified by about three times by the amplifier circuit 24 and input to the measurement unit 30. The voltage value here is, for example, 200 mV or more at 0.1 Hz to 10 Hz and 800 mV or less at 10 Hz to 50 Hz.

The voltage input to the measuring unit 30 is converted into a digital voltage signal by the A / D conversion means 32, and is 0.1 Hz to a frequency band of 10 Hz or less by the digital low pass filter as the first filter means 34a. The voltage signal (first measured voltage) of 10 Hz is extracted. In addition, a voltage signal (second measurement voltage) in the frequency band of 10 Hz to 40 Hz is extracted by the digital band pass filter, which is the second filter means 34b.

The first measured voltage is determined by the first comparing means 36a to determine whether the voltage value is 200 mV or more. In addition, the second measured voltage determines whether the voltage value is 800 mV or more by the second comparing means 36b. Since the slot machine 1001 is greatly deformed, since the voltage of 200 mV or more is measured by the first measuring means, the deformation detection signal is transmitted to the main control board 1021.

In addition, when the slot machine 1001 is strongly beaten by the inductor, the vibration is conducted to the horizontal frame 1311 in which the vibration detection device 1 is fixed. As a result, a voltage including a frequency band of 10 Hz to 40 Hz, which is a frequency characteristically generated on tapping from the detection unit in the vibration detection device 1, is generated. The voltage is amplified by the filter circuit 22 by a frequency other than 0.1 Hz to 50 Hz and then amplified by about three times by the amplifier circuit 24 and input to the measurement unit 30. The voltage value here is, for example, 800 mV or more at 10 Hz to 40 Hz, and 200 mV or less at 0.1 Hz to 10 Hz.

The voltage input to the measuring unit 30 is converted into a digital voltage signal by the A / D conversion means 32, and a voltage signal of 0.1 Hz to 10 Hz, which is a frequency band of 10 Hz or less, by the digital low pass filter (first measurement Voltage) is extracted. In addition, a voltage signal (second measurement voltage) in the frequency band of 10 Hz to 40 Hz is extracted by the digital band pass filter.

The first measured voltage is determined by the first comparing means 36a to determine whether the voltage value is 200 mV or more. In addition, the second measured voltage determines whether the voltage value is 800 mV or more by the second comparing means 36b. Since the vibration is generated by striking the slot machine 1001 strongly, since the voltage of 800 mV or more is measured by the second comparing means 36b, the tap detection signal is transmitted to the main substrate.

The processing by the main control substrate 1021 for cheating is the same as that in the first embodiment, and the lamp, the speaker, the liquid crystal display, etc., depending on the type of the notification to the owner and the notification to the attendant (cheating, damage). By appropriately.

As shown in FIG. The main control board (not shown) in the main control board case 2050 is connected to the output side of the vibration detecting device 1, and processing for illegal behavior is performed in accordance with the signal from the vibration detecting device 1.

In this embodiment, the vibration detection device 1 causes the user to open the main door 2020 forcibly to steal money (theft) and to vigorously hit the vending machine 2001 (damage). Behavior) at the same time. In this case, when external force is applied over time such as deformation due to theft, a voltage having a frequency band of 0.1 Hz to 10 Hz, particularly a voltage of 1 Hz to 5 Hz, is characteristically generated in the detector. In addition, when a momentary impact such as tapping due to a damage action is applied, a voltage having a frequency band of 10 Hz to 40 Hz, particularly a voltage of 20 Hz to 40 Hz, is characteristically generated in the detector.

Since the configurations of the filter circuit 22 and the amplifier circuit 24 are the same as those in the first embodiment, they are omitted. In the measuring section 30, a digital bandpass filter for filtering a voltage signal in a frequency band of 1 Hz to 5 Hz as the first filter means 34a, and a voltage signal in a frequency band of 20 Hz to 40 Hz as the second filter means 34b. A digital band pass filter is used, and the strain threshold is 200 mV, and the tapping threshold is used in two types, 400 mV and 800 mV.

The vending machine 2001 has various installation places, and especially when it is installed outdoors, it is influenced by various vibrations. For this reason, malfunctions increase if it is not possible to accurately detect vibration caused by deformation or tapping. Therefore, the voltage was measured in a narrower frequency band than in the case of pachinkogi.

In addition, the vending machine 2001 is often located at a place away from the installation place, and the user often makes jokes such as knocking. Therefore, if a notification or the like is given for an impact that does not cause damage, the normal operation will be disturbed. However, even if the impact is not caused to damage, it can be expected to reduce the play by preventing this. Therefore, two kinds of tapping thresholds are set, and it is set as the structure which can process according to the magnitude | size of a tapping method. About the measurement part 30, since the other structure is the same as that of Example 1, it abbreviate | omits.

The operation example of the vibration detection apparatus 1 is shown. When a user tries to forcibly open the main door 2020 of the vending machine 2001, the deformation occurs in the main door 2020 in which the vibration detecting device 1 is fixed. As a result, a voltage including a frequency band of 0.1 Hz to 10 Hz, which is a frequency characteristically generated from deformation, is generated from the detection unit 20 in the vibration detection device 1. The voltage is amplified by the filter circuit 22 by a frequency other than 0.1 Hz to 50 Hz and then amplified by about three times by the amplifier circuit 24 and input to the measurement unit 30. The voltage value here is, for example, 200 mV or more at 0.1 Hz to 10 Hz, and 400 mV or less at 10 Hz to 50 Hz.

The voltage input to the measuring unit 30 is converted into a digital voltage signal by the A / D conversion means 32, and the voltage signal in the frequency band of 1 Hz to 5 Hz by the digital band pass filter which is the first filter means 34a. (First measurement voltage) is extracted. Further, the voltage signal (second measurement voltage) in the frequency band of 20 Hz to 40 Hz is extracted by the digital band pass filter, which is the second filter means 34b.

The first measured voltage is determined by the first comparing means 36a to determine whether the voltage value is 200 mV or more. In addition, the second measured voltage determines whether the voltage value is 400 mV or more or 800 mV or more by the second comparing means 36b. Since the main door 2020 is greatly deformed, since the voltage of 200 mV or more is measured by the first measuring means, the deformation detection signal is transmitted to the main control substrate.

In addition, when the main door 2020 is strongly knocked by the user, the vibration is conducted to the main door 2020 in which the vibration detecting device 1 is fixed. As a result, a voltage including a frequency band of 10 Hz to 40 Hz, which is a frequency characteristically generated by tapping from the detection unit 20 in the vibration detection device 1, is generated. The voltage is amplified by the filter circuit 22 by a frequency other than 0.1 Hz to 50 Hz and then amplified by about three times by the amplifier circuit 24 and input to the measurement unit 30. The voltage value here is, for example, 400 mV or more at 10 Hz to 40 Hz, and 200 mV or less at 0.1 Hz to 10 Hz.

The voltage input to the measuring unit 30 is converted into a digital voltage signal by the A / D conversion means 32, and the voltage signal in the frequency band of 1 Hz to 5 Hz by the digital band pass filter which is the first filter means 34a. (First measurement voltage) is extracted. Further, the voltage signal (second measurement voltage) in the frequency band of 20 Hz to 40 Hz is extracted by the digital band pass filter, which is the second filter means 34b.

The first measured voltage is determined by the first comparing means 36a to determine whether the voltage value is 200 mV or more. In addition, the second measured voltage determines whether the voltage value is 400 mV or more or 800 mV or more by the second comparing means 36b. Thus, when the voltage of 400 mV to 800 mV is measured by the second measuring means, the tap detection signal (small) is transmitted to the main board, and when the voltage of 800 mV or more is measured, the tap detection signal (large) is applied to the main board. Is sent.

The processing by the main substrate (not shown) for cheating will be described. When a deformation detection signal or a tapping detection signal (large) is input to the main substrate, the criminality is high, so that a response by voice, light, or the like is made, and the security company is notified. In addition, when a tapping detection signal (small) is input to the main control board, the criminality is low and it is considered to be a simple joke or an accident. Therefore, attention to voice, light, etc. is kept, and no notification is given to the security company.
