To meet with requirements of tunnel micro-seismic monitoring system
like stability and multi-channel data parallel acquisition
a multi-channel microseism acquisition station based on Zynq—7000 is designed. In the programmable logic( PL) part of this chip
the logic state machine is used to control external 12—channel ADC parallel acquisition. Then programmable system( PS) part completes PL peripheral kernel driver module and application program
data interaction from kernel space to user space and between multithreadings of application layer is realized by double-buffer operation idea. The station has the characteristics of high hardware integration and channel number is customizational. The results show that the system can accurately collect the vibration signal and has certain practical application value.
