A demonstration implementation of a distributed data-processing hospital information system using an intelligent local area communications network (LACN) technology is described. This system is operational at the UCSF Medical Center and integrates four heterogeneous, stand-alone minicomputers. The applications systems are PID/Registration, Outpatient Pharmacy, Clinical Laboratory, and Radiology/Medical Records. Functional autonomy of these systems has been maintained, and no operating system changes have been required. The LACN uses a fiber-optic communications medium and provides extensive communications protocol support within the network, based on the ISO/OSI Model. The architecture is reconfigurable and expandable. This paper describes system architectural issues, the applications environment, and the local area network.
本文描述了一个使用智能局域网（LACN）技术的分布式数据处理医院信息系统的示范实现。该系统在加州大学旧金山分校医学中心运行，集成了四台异构的独立小型计算机。应用系统包括患者识别/挂号、门诊药房、临床实验室和放射科/病历。这些系统保持了功能自主性，无需更改操作系统。LACN使用光纤通信介质，并基于ISO/OSI模型在网络内提供广泛的通信协议支持。该架构可重新配置和扩展。本文描述了系统架构问题、应用环境和局域网。
