摘　　要：针对当前临床实验室仪器与计算机系统间的通信需求,研究国际上普遍采用的ASTM E1831,ASTM E1394标准,基于DCOM技术和ASTM标准提出一种相对通用的联机通信设计方案,包括多层分布式应用、ASTM标准通信实现和数据收发多线程处理。实现具有标准化接口的实验仪器与计算机系统之间的双向信息传输,不仅业务变更灵活,而且有利于运算均衡。Considering the demand of communication between clinical laboratory instruments and computer system, this thesis studies the international standards ASTM E1381 and ASTM E1394, and puts forward a relatively common solution based on DCOM and ASTM, including multi-tier distributed application, ASTM communication implementation and sending/receiving data by multi-thread. The application accomplishes two-way information transmission between laboratory instruments with standardized interface and computer system. It not only can flexibly switch operation, but also is helpful to load balancing.
