| Abstract: | 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. |
