本文介绍了一种适用于实验室环境的异种机星形网络。运用异步串行通信技术,通过RS-232串行接口将实验室信息管理系统LIMS主机与分析仪器的计算机、实验室微机连接成计算机网络并开发了六种通信软件,有效地解决了实验室异种机数据通信的问题。文中对这种网络的结构、通信线路的连接方式、通信软件的功能和汉字信息传输的原理作了介绍。
This article describes a heterogenous machine star network suitable for laboratory environments. Using asynchronous serial communication technology, computer and laboratory computer of LIMS mainframe and analytical instrument of laboratory information management system are connected into a computer network through RS-232 serial interface and six kinds of communication software are developed to effectively solve the problems of different kinds of laboratory Machine data communication problems. This paper introduces the structure of this network, the connection of communication lines, the function of communication software and the transmission of Chinese characters.
