针对目前数据采集系统中的大容量传输问题,采用PCI总线设计开发了一种新的数据采集系统,介绍了PLX9054芯片的EE-PROM的配置方法,详细地研究了PCI9054从模式的读写时序,重点讲解了板卡设计开发中的难点和细节,同时还给出了上位机软件的开发方法;实验结果表明,本地采集速率可达30MB/s,传输速度有了显著提高,具有一定的实用性和推广价值。
In view of the recent problem of mass data transfer in data acquisition system,we design and develop a new system with the PCI bus.The Article detailed analyses the read-write succession of PCI9054 target mode,introduces the configuration of PLX9054 chip EEPROM and explains the difficulty and details in the design and development of card with emphasis.IN addition,it also gives the method of exploitation about superior machine software.The experimental result indicated that this locality gathered the speed to be possible to reach 30MB/s,the transmission speed had the remarkable enhancement.The technology and methods adopted in the system are practical and worthy of using abroad.
