机场油库油品泄漏监测的无线传感器节点设计

根据对机场油库油品泄漏的无线网络化监测方式需求,采用光离子化传感(PID)技术,设计了一种基于MSP430单片机与CC2520射频通信相结合,并以锂电池供电结合太阳能补给的低功耗无线传感器节点。该节点以低电压工作的PID集成器件配合专门设计的主动式集气装置,并采用集成温度传感器进行温度补偿。对该节点用于机场油库油品泄漏检测的有效性分析和功耗估计表明,可以满足无线网络化监测油品泄漏的要求。提出了一种新的机场油库油品泄漏监测报警系统设计方案,综合应用检测技术、计算机技术、无线网络技术等,研究设计集气装置,并采用节点协同监测及节点低功耗设计等,使整个系统体现了智能化、安全可靠、节能实用的设计原则,可以满足机场油库现场实际监测需求。

Study on Detection Technique for Pipeline Leakage

Pipeline in te grity defect is a considerable portion in all the defects.Therefore, the study o n detection technique is of great concern to the owners of pipelines. A real ti me monitoring system of pipeline defect is established. For unexpected accidents of pipeline leakage, several methods of signal processing, including wavelet an alysis are utilized. The leakage can be located accurately in time. This system is applied to many long distance pipelines in China, which has made great contri butions to the economy.
