【摘要】 大气污染问题突出且日益严重,对大气环境实时准确地监测具有重大社会意义。现有的监测手段实时性差、维护困难,难以满足实际需求。针对上述情况,设计了一种基于Zig Bee技术的大气监测系统,并详细阐述了系统的整体框架结构和实现方案。系统包括无线传感器网络和远程监测中心2个部分。其中无线传感器网络包括传感器节点和网关节点。传感器节点以CC2530为核心搭建,负责采集大气环境数据并通过多跳方式将数据实时发送至网关节点;网关节点以LPC2138为核心搭建,负责汇总传感器节点的数据并通过GPRS实现与远程监测中心的通信。远程监测中心使用在Microsoft Visual C++6.0环境下编制的监测软件,通过网络模块完成数据接收、显示及存储,为用户提供一个友好的人机界面。更多还原

【Abstract】 Air pollution problem is becoming increasingly serious.Therefore,an accurate air monitoring system is of great social significance.However,the existing monitoring means has poor real-time,hard to maintain,and difficult to meet actual need.Aiming at these circumstances,an monitoring system based on Zig Bee technology is designed and the whole frame structure and implementation scheme is described.The system includes two parts:wireless sensor networks and remote monitoring center.The wireless sensor networks consists of sensor nodes and gateway nodes.The sensor nodes are built with CC2530 which are responsible for collecting air environment datas and sending data in real-time to the gateway nodes through multi-hop mode,and the gateway nodes are built with LPC2138 which is responsible for collecting datas of sensor nodes and communicates with remote monitoring center via GPRS.The remote monitoring center uses monitoring softwave programmed in Microsoft Visual C + + 6.0,accomplishes data receiving,displaying and storage,through network module,which provide a friendly interface of man-computer.更多还原
