【摘要】 针对目前广泛存在的油气管道受到人为破坏的问题,本文提出了通过对管道周围的人、车辆等发出的震动信号进行采集,对信号特征进行分析,从而对目标进行分类识别,并根据信号到达各传感器的时间差通过三角定位原理实现对入侵目标的空间定位以及对目标的运动轨迹进行监测,从而对管道安全构成威胁的行为进行早期监测、定位和预警。更多还原

【Abstract】 Aiming at the man-made destructive problem on oil pipelines, this paper proposes method that is to collect seismic signals and make analysis into its characteristics, working out classified identification on them. Based on triangle location principle, this method can identify the interspaced location and monitor the track of the target’s movement by analyzing time of the signal’s arrival to these sense organs, finally make early monitor , localization and advance alarm of the threats to pipeline’s safety.更多还原
