摘要：NOVELTY - The device has an acceleration sensor (U1) utilized to obtain first path signal and second path signal through a constant current source (U2) by an active band-pass filter circuit (U4). Third path signal is obtained from a speed sensor (U12) by an active RC low-pass circuit (U14). Fourth path signal and fifth path signal are obtained from a mechanical sensor (U17) through an active low-pass filter circuit (U19). Obtained path signals are transmitted to A/D converter through a differential amplifying circuit (U6). The constant current source is provided with a voltage power supply chip. USE - Pile integrity analysis teaching experimental platform signal synchronous collecting device. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a pile integrity analysis teaching experimental platform signal synchronous collecting device.
