摘　　要：针对血液分析仪需在8 s内完成4路血细胞和1路状态信号数据采集、处理的要求,设计一套基于现场可编程门阵列的多路数据采集与处理系统.系统实现5路数模转换的并行数据采集、数据处理,并通过串行外设接口通讯接口将处理的数据上传至ARM主机.临床试用结果表明,系统数据采集和处理的方法完全满足血液分析仪对测试速度的要求,仪器性能指标达到了国家注册检验的要求.We present a new multi-channel data acquisition and processing system based on field programmable gate array（ FPGA） for hematology analyzers. This system is able to acquire four-channel data of blood cells and process one channel status signal in eight seconds. The digital to analog converter for the total five data channels is implemented in parallel. The processed data are transferred to ARM host via the serial peripheral interface communication protocol. Clinical trials indicate that the new system fulfills the strict requirement for the test speed of hematology analyzers,and its performance meets the national registered inspection standard.
