摘　　要：在研究了lontalk协议的基础上,提出了一种基于Xilinx XC3S200型FPGA和PCI的lonworks总线数据采集卡的设计方案;PCI桥接芯片PCI9052实现本地端与计算机的数据传输,FPGA的逻辑设计根据实际应用需求实现部分LonTalk协议,完成对lonworks帧的解封和数据存储;该采集卡目前已运用于和谐1型大功率交流机车制动系统的数据采集,运行效果良好,证明了设计方案的合理性。A method of designing Lonworks data acquisition card based on Xilinx XC3S200 FPGA and PCI is presented in the paper, after researching the protocol of Lontalk. PCI Bridged Chips PCI9052 achieved the local side and the computer side connecting. The logic design of FPGA controlled the Decoding frame of Lonworks and data storage, according to the the protocol of Lontalk and the application. This instrument is now used for data sampling of brake system of HXdl locomotive successfully, the rationality of the method has been proved,
