[0025] Specifically, the vibration sensor 6 is a piezoelectric vibration sensor. The charge amplification circuit converts the charge amount output by the piezoelectric vibration sensor into a voltage signal. The filter amplification circuit denoises and amplifies the output voltage of the charge amplification circuit.

[0026] As shown in the Figure 3 charge amplification circuit includes resistors R8, R9, and R10, capacitors C4 and C5, and a first operational amplifier. The output end of the vibration sensor 6 is connected with one end of the capacitor C4. The other end of the capacitor C4 is connected with one end of the resistor R8. The other end of the resistor R8 is connected with the inverting input terminal of the first operational amplifier. One end of the resistor R9 is grounded. The other end of the resistor R9 is connected with the non-inverting input terminal of the first operational amplifier. One end of the resistor R10 and the capacitor C5 connected in parallel is connected with the inverting input terminal of the first operational amplifier. The other end of the resistor R10 and the capacitor C5 connected in parallel is connected with the output end of the first operational amplifier. The power supply end of the first operational amplifier is connected with ±15V voltage. The output end of the first operational amplifier is connected with the input end of the filter amplification circuit.

[0027] Specifically, the charge amplification circuit is a negative feedback type charge amplification circuit with a capacitor and a resistor in parallel, in order to reduce the drift of the charge amplification circuit at the DC operating point, the feedback resistance value is designed to be 8GΩ, considering that the sensitivity of the piezoelectric vibration sensor is 25C / gn, and the measurement range is 0-100gn, according to the formula, the feedback capacitance is calculated to be 10nF, and the TL081 operational amplifier with high input impedance and low noise is selected, which has the advantages of stable operation and low cost.
