摘要
为了准确的分析地下石油的储量和位置,需要在施工测线上大量的物理点同时观测地震波并对其进行分析,文章中设计了一款石油勘探多通道数据采集系统;FPGA是系统的主控制模块,其硬件资源按功能可划分为A/D、D/A逻辑控制,时钟分频,数据缓冲区控制,电源监控,双端口逻辑控制,PCI9054控制等功能;FPGA通过PC104+总线与上位机进行数据传输;该系统经过时序仿真及硬件调试,已经达到了多通道数据采集的各项指标,验证了最初设计思想的正确性。
Aimed at determing the reserves and location of petroleum, a system applied to collecting multichannel data for petroleum based on FPGA （ Field Programmable Gate Array ） has been designed. As the logic control center, the hardware resources of FPGA have been partitioned into several function modules, which will implement the A/D convertion, D/A convertion, frequency splitting, data buffer control, power--supply voltage monitor, dual--port logic control and PCI9054 control in the mutichannel,data acquisition system. Then the data will be transferred to computer through a PC104plus bus. The system could also be applied in multi--analog signals test and hardware debugging.
