| 摘要: |
| 提出并实现了一种基于PCI总线六通道高速采集系统的结构。该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，可以实现六通道同时采集和大容量数据的存储；为了实现高速和大容量采集，系统采用S5933 作为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；控制电路采用FPGA实现，简化了电路板设计，提高了灵活性。软件系统在Windows NT平台上实现，保证了整个系统的安全性与稳定性。 |

| Abstract: |
| This thesis presents a system architecture of six-channel high speed data acquisition on PCI bus and implement it. This system, using a PC as the control unit, can be used to get data from three different kinds of radar, and implement data acquisition through six channels, and store large amount of data. In order to realize high speed and large amount acquisition, we use S5933 as PCI interface, using the high transfer speed of the PCI bus,satisfying the required data transfer rate between the control unit and the acquisition unit. At the same time we use dual-port RAM to provide continuous acquisition；and use FPGA to implement the control circuits, simplify the circuit board design and improve the flexility of the design. In order to ensure the security and stablity of the whole system,we implement the software system under Windows NT operating system |
