一种基于无线传感网络的色谱工作站硬件设计

Design of Data Collector of Chromatograph Workstation Based on Wireless Sensor Networks

常见的色谱工作站采用的是有线连接,这种点对点的连接方式存在着系统扩展性差、安装繁琐、布线距离及走向限制等问题。为此,设计出一套基于ZigBee的无线色谱工作站,在传统色谱工作站的基础上,利用无线射频(RF)技术,实现了一台计算机与一个或多个色谱仪之间的无线连接,并具备自动组网、智能匹配、丢包补发等功能。

Most existing chromatograph workstations,which are based on wired connection,have restrictions in expansibility and setting up.This paper describes a new design of chromatograph workstation based on ZigBee,which connects one or many chromatograph detectors with computers wirelessly.Additionally,the system can match device intelligently and deal with packet loss.
