| 摘 要： | 现代地球物理学科要取得更好更快的发展,需要汲取最新技术提升地球物理数据采集精度。而可编程片上系统(SoPC)技术是一种基于FPGA的灵活、高效的片上系统解决方案,为研制新型高精度地电数据采集装置提供了一条新途径。介绍了应用SoPC技术来研究并设计遵从CS5372芯片工作时序的A/D转换芯片控制器及串并转换模块,借助Matlab、DSP Builder工具的FIR重采样数字滤波器,在QuartusⅡ环境下合理集成NIOS II软核模块,并结合LabVIEW开发的上位机软件,实现了用Cyclone系列芯片替代昂贵的CS5376进行高精度地电数据采集。结果表明,采用SoPC技术可大大提升高精度地电数据采集系统的性能,且可将地电数据采集中的数字电路部分全部整合到一片SoPC芯片上。这为解决复杂地电条件提供了一种有效途径。

| Abstract: | To get better and faster development,modern geophysics needs to draw upon the latest technologies to promote the acquisition precision of geophysical data.System on Programmable Chip(SoPC) is a flexible and efficient SoC solution based on FPGA,which provides a new way to develop novel high-precision geoelectric data acquisition device.This paper introduces the application of SoPC technology to the research and design of an A/D conversion controller which complies with the time sequence of CS5372,a module conversing the serial data to parallel one,a resampling FIR digital filter using Matlab and DSP Builder,a NIOS II Soft IP Core integrated by Quartus Ⅱ and a PC software designed with LabVIEW.Under the application of equipments mentioned above,Cyclone chips which replace expensive CS5376 can be used to realize the acquisition of the high-precision geoelectric data.As the result shown,the use of the technology of SoPC can greatly improve the cost performance of high-precision geoelectric data acquisition devices and also can integrate the digital parts of geo-electric data acquisition devices into a chip,which also provide an effective way to solve problems under the complex geoelectric condition. |
