摘要
提出一种 PCI总线多通道高速采集系统的结构并予以实现。这个系统采用微机作为采集主控单元 ,兼容三种体制雷达的采集要求 ,可以实现六通道连续采集 ,并可以实现大量数据的存储 ;为了实现高速和大容量采集 ,系统采用基于 S59933的 PCI总线接口 ,利用 PCI总线的高速传输能力 ,满足主控单元与采集单元的数据传输要求 ;同时利用双口 RAM内部切换保证连续采集和连续传输 ;控制采用 CPLD集中实现 ,简化了电路板设计 ,提高了灵活性。
A system architecture of multi channel high speed data acquisition on PCI bus is given. The system uses a PC as the control unit to get data in three different kinds of radar, and implements data acquisition through six channels for storing large amount of data. In order to realize high speed and large amount of data acquisition, the system uses the S5933 based PCI interface through the high transfer speed of the PCI bus,to satisfy the required data transfer rate between the control unit and the acquisition unit, and uses Dual Port SRAM to provide continuous acquisition, and CPLD to implement the control circuits. The design of circuit board is simplified and the flexility of the system is improved.
