摘要
无线传感器网络技术已日趋成熟,为了能实时、有效地对污染气体排放企业进行监控,可采用Zigbee技术对污染气体进行自动监测。设计中的无线收发模块采用XBee-PRO DigiMesh 900芯片,利用单片机作为控制芯片,通过无线通信方式形成的一个多跳自组织网络,将采集的数据经过处理变成串行数据后发送给汇聚节点,再由汇聚节点发送到控制中心。利用NS2进行了网络仿真,通过仿真,网络运行良好,丢包率低,延迟时间短,满足系统自动监测的需求。
Wireless sensor network technology has become more and more mature. In order to conduct real-time and effec- Q tive monitoring for pollution emission enterprises, Zigbee technology can be used in automatic monitoring systems for polluted gas. The wireless transceiver module uses XBee-PRO DigiMesh 900. The single chip microcomputer is taken as control chips. A multiple hops self-organization network is formed by the mode of wireless communication, which will process The acquisited data are processed and converted into serial data, sent to gathering node, and then sent to the control center from gathering node. The network simulation was performed by the aid of NS2. The simulated results show that the network runs well, packet loss rate is low, and delay time is short. Therefore, it meets the needs of automatic monitoring system.
