摘　　要：根据落锤动态标定装置的工作原理，提出了一种改进标定方法，依据此标定方法的需要设计了一套对多路瞬态信号采集的硬件控制电路。信号采集电路主要由硬件电路控制信号的转换，信号转换速度不受MCU工作速度的限制，工作中信号采集的速度和采集的数据点数都可以通过MCU进行设置，本硬件控制电路主要基于CPLD来实现。In this paper, on basis of the principle of drop hammer device, a new calibrating method is presented. According to the method a control circuit is designed of multichannel signal acquisition. The signal conversion is controlled by hardware circuit and conversion speed isn＇t confined by working speed of MCU. Acquisition speed and digital information point are setted by MCU, the hardware control circuit is achieved based on CPLD.
