无线传感器网络在油田数据传输系统中的应用

基于无线传感器网络和GPRS/CDMA技术构建了油田数据监控系统,将数据传输网络分为两级网络结构,现场层次由ZigBee树形网络实现,普通节点数据经小区中心节点和GPRS/CDMA网络发送至远程数据服务器层。介绍了整个系统硬件结构和应用程序服务内容,重点讨论了现场网络节点设计。针对野外节点工作环境,设计了高效率的DC/DC电路、快速动态电源路径选择电路和低功耗的RF电路。初步试验表明:可以满足工作需要,具有物理结构简单、安装维护方便、运营成本低等优势。

Wireless Sensor Network Application in Oilfield Data Transmission System

Based on wireless sensor network and GPRS/CDMA technology,an oilfield data monitoring system was designed,whose data transmission network structure included field level and server level.The field level included common node and center node based on ZigBee tree network and the center node sent data to the remote server via GPRS/CDMA.The system hardware structure and server application strategy were discussed,especially field network nodes.According to the field environment,the high efficiency DC/DC circuit,fast dynamic power selection circuit and low-power RF circuit were designed.The test shows that the system has meet actual need,and has advantages of simple physical structure,convenient installation and maintenance,low operation cost,compared with other designs.
