[ Pass filter 140 for passing only an interlayer noise signal mainly having a low frequency band by eliminating a high frequency noise intervening in a detected interlayer noise signal and a static electricity preventing static electricity And a cable connected to the terminal portion 170 of the interlayer noise signal detecting module 100 of the present invention and the interlayer noise signal controlling module 200 Comprises a reverse voltage protection unit 160 can be prevented from emitter reverse voltage is incoming.

More specifically, the sensing unit 110 of the inter-layer noise signal sensing module 100 according to the present invention includes a sensor unit 111, a noise elimination low-pass filter 112, and a reverse current prevention unit 113 .

The sensor unit 111 of the sensing unit 110 can be applied irrespective of the type of sensor if it detects an interlayer noise signal such as noise, impact sound (weight and weight) and vibration and generates a potential difference. Specifically, the sensor unit 111 is a low-cost, low-power piezo-vibration sensor capable of promptly responding to minute interlayer noise acting on the outside in order to provide high sensitivity at low frequencies. In the Piezo Vibration Sensor, one end of a vibration beam is fixed to a fixed end, and the other is a free end, and a mass is mounted at a predetermined position of the end portion, so that the vibration beam and the mass are integrally When the beam is horizontally mounted, it is possible to provide a vibration sensor capable of providing a high sensitivity at a low frequency, in which, when the beam is mounted horizontally, the vibration beam is accelerated to the vertical plane due to inertia of the mass attached to the other end of the vibration beam, According to the principle, it senses the magnitude of the vibration for the interlayer noise signal such as the vibration sound and the impact noise applied from the outside proportional to the change of the resonance frequency of the beam, and generates a potential difference in direct proportion to the magnitude of the applied vibration.

Accordingly, the circuit elements of the inter-layer noise signal sensing module 100 are protected from static electricity (ESD) that may be generated from the outside, that is, from the ambient environment of the sensor or human body contact.

The reverse voltage prevention unit 160 of the interlayer noise signal detection module 100 according to the present invention connected to the static electricity protection unit 150 detects the output of the interlayer noise signal detection module 100 using the reverse voltage prevention diode The circuit elements of the interlayer noise signal sensing module 100 according to the present invention are protected by preventing the reverse voltage from being drawn from the interlayer noise signal control module 200 connected to the terminal portion 170.
