摘要
研究了盗油实时监测报警系统.此系统可及时发现盗油对输油管道的破坏,避免管道泄漏及原油被窃取.研究应用应力波检测的原理对人为破坏管道进行监测.采用主站基站主从式无线通讯的方式,进行数据的传输以及盗油的报警定位.根据现场测试的数据,选择应力波检测模式,并分析了应力波信号随检测距离的时频特性变化.系统对应力波信号的检测距离达到了1km,取得了较好的检测效果,降低了系统造价.
In this paper a system for on line monitoring the oil stealing is investigated. The system can detect the man-made destroying of oil pipelines in time, and thus can avoid pipeline leakage and oil stealing. The stress wave detection technique is employed for monitoring the man-made destroying. A server/client communication between the host station and nodes is adopted to transfer data, alarm and locate where the oil stealing happens. According to the filed data, the mode of stress wave to be picked up is selected and the characteristic changes of stress wave signals in time and frequency domain are analyzed. The distance of stress wave detection is more than 1km and the system cost is reduced.
