地震物理模拟系统设计技术

The design technology about the system of seismic physical simulation

地震物理模拟系统主要由定位系统和数据采集系统组成。定位系统设计开发中应用FPGA可编程器件,实现了对光栅返回脉冲的噪声信号处理,可靠计数、锁存和同步信号的实时触发功能。采集系统采用USB2.0技术,实现对模拟地震数据的高速采集传输。

the system of seismic physical simulation mainly includes the location system and the data acquisition system. The location system is particularly developed by FPGA （Field Programmable Gate Array） ,which can complete the functions such as the accurate counting and the noise processing about the feedback pulse from raster ruler , and execute the fast trigger on the synchronization signal generator. The section of data acquisition system is based on the USB2.0 technology , which finish the transmission of seismic simulation data on high speed.
