摘　　要：针对隧道微地震监测系统对系统稳定性及多通道数据并行采集的需求,设计了一种基于Zynq-7000平台的多通道微地震数据采集节点。在Zynq-7000芯片的PL部分采用逻辑状态机实现外部12路ADC并行采集控制,在PS部分编写PL外设内核驱动模块及应用程序,内核空间到用户空间以及应用层多线程之间采用双缓存乒乓操作思想实现数据交互。同时该采集节点具有硬件集成度高、通道数可定制的特点。实验结果表明:该系统能够准确地采集到震动信号,具有一定的实际应用价值。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.
