摘要：NOVELTY - The device has acceleration sensors (U1, U7) connected with a first chip (U8) through a constant current source (U2) for processing active band pass circuits (U4, U9) through followers (U5, U10). An analog-to-digital (AD) conversion unit (U27) is connected with an analog differential amplification circuit (U6) and an input pin (U11). A speed sensor (U12) is connected with the first chip. Two mechanical sensors (U17, U22) are fixed with a second chip (U18). Differential amplifying circuits (U21, U26) are connected with the AD conversion unit. The speed sensor collects a signal. USE - Foundation pile integrity analysis teaching experimental platform synchronous data signal collecting device. ADVANTAGE - The device can realize synchronous data signal acquisition operation by using five sensors in an effective manner. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a foundation pile integrity analysis teaching experimental platform synchronous data signal collecting device.
