基于ZigBee的数据采集系统设计

Design of Data Collection System Based on ZigBee

数据采集系统是由工作站和传感节点构成,传感节点被放置在不同的区域内,起采集现场环境数据的作用,工作站则是用于对所采集的数据进行分析和处理。目前,在该类系统中,工作站和传感节点之间可以采用有线或无线两种方式进行联网。采用无线方式联网具有安装便捷、使用灵活、经济节约、易于扩展等特点。本文采用ZigBee无线技术来组建现场工作站系统网络,从而构建一个基于ZigBee的无线数据采集系统,该系统能提供给用户通用的无线互联硬件模块和软件开发接口,便于用户快速构建相应的系统。

Data collection system is made up of a workstation and sensor nodes. Sensor nodes are placed in different areas, which are used to collect environmental data. Workstation is used to analyze and handle data of collection. At present, there are two ways （wired and wireless ways） to connect workstation and sensor nodes. Wireless connected way has the characteristics of fixing easily, using flexibly, economy, expanding easily and so on. A new ZigBee technology is used to organize network of locale workstation to construct a wireless data collection system based on ZigBee. The system can provide user common wireless connected hardware modules and software developing interface in order to construct corresponding system fast.
