【摘要】 文章给出了一种可控震源地震系统中的扫描信号发生器的设计。采用嵌入式ARM微处理器S3C2410和数字信号处理芯片TMS320VC5402的双核架构,研究设计了基于Qt/Embedded的设置扫描信号参数的图形界面,完成了Linux系统下HPI驱动程序设计以及用DSP产生扫描信号的软件设计。通过测试,观测在DSP端信号输出端生成的波形,获得了符合特定设置要求的扫描信号波形,满足系统的设计要求。更多还原

【Abstract】 This paper presents a sweep signal generator design in vibroseis system.It applies the dual-core architecture of embedded microprocessor S3C2410 and digital signal processor TMS320VC5402,It designs graphical interface of sweep signal parameter based on Qt/Embedded,finishes the HPI driver design under Linux and the software design of sweep signal produced by DSP.The test and observation of the waveform on the signal output port of DSP show the sweep signal waveform which correspond with special setting requirements is acquired,which proves that the system has achieved the designed goal.更多还原
