Design of oilfield wireless monitoring system based on ZigBee and WiFi

针对油田数据的采集监测及远程应用的需求,提出了一种用于油田的无线网络系统。该系统将Zig Bee技术与Wi Fi技术相结合,实现监测信息的无线传输;传感节点以XBee PRO S2B为主控芯片,通过电量、压力、载荷、位移、温度传感器实时采集项目数据,采集到的数据通过Zig Bee网络传至Zig Bee-Wi Fi中继转换器转送至Wi Fi网络,转换器既作为Zig Bee网络的协调器,又作为Wi Fi网络的节点;通过Zig Bee网络与Wi Fi网络的结合,数据可以在移动手持设备上显示并并进行分析。系统实现了油田的远程监测、2种通信技术的转换及低功耗、高速率数据传输,使油田数据的采集更加方便、灵活。

In order to overcome the limitations of traditional industrial cable data acquisition system,a kind of wireless network system is proposed to meet the needs of oilfield data acquisition,monitoring and remote application. The system realizes the wireless transmission of monitoring information by combining ZigBee technology with WiF i technology. The real-time data acquisition of the system is implemented by electricity,pressure,load,displacement and temperature sensors,the collected data is transported to WiFi network through ZigBee-WiFi relay converter. XBee PRO S2 B is as the main chip of sensor nodes. The relay converter is both a coordinator of ZigBee network and a node of WiFi network. The collected data can be displayed on a mobile handheld device and analysed by combining ZigB ee network with WiFi network. The system realizes the remote monitoring in oil fields,completes the conversion between two kinds of communication techniques,and realizes the low-power consumption and high-speed data transmission. It makes the oilfield data acquisition more convenient and flexible.
