Abstract: 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.

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。
