Abstract: To ensure panoramic monitoring at stations along oil and gas pipeline, and reduce the false alarm rate of border guard system, a new border guard system is designed by integrating the correlation and double-guide detection. According to the characteristics of stations and the correlation and double-guide detectors, the correlation and double-guide detectors are installed on ordinary fence and at fence corner respectively. The applications prove better security, no false or missing alarm. Therefore, it meets the requirements for timely and accurate alarm at stations.
