Application in Oil and Gas Pipelines Security of Multi-Dimensional Three Kam Detection Technology

摘要: 为了确保输油气管道站场的安全性，针对对射类探测技术“误报率高”、振动光缆探测技术“误报率低，但功耗要求高、投资高”的缺点，提出了低功耗、低投资且误报率极低的多维三鉴探测技术，该技术通过探测器中陀螺仪、加速度传感器、压敏传感器感知周围各种振动数据，信号采集从传统的一元变成三元，在三个维度中建立多变量模型式，更精确的区分入侵及干扰，大大降低了误报率，同时采用了低功耗设计，非常适合油气管道站场及阀室的入侵探测要求，通过实际应用发现，多维三鉴探测技术大大降低了误报率，同时节省大量投资，应用功能效果很好。

Abstract: In order to ensure the safety of oil and gas pipeline sites, aiming at radiation detection technology “high false alarm rate”, and “low false alarm rate, but high power consumption and high investment”, low investment and low false alarm rate multi-dimensional three Kam detection technology will be put forward: The technology senses the vibrations through the detector gyroscope, acceleration sensor, pressure-sensitive sensors, signal acquisition from the traditional one latitude to third la- titude, establishing multivariable model in the three dimensions to distinctmore accurately between invasion and interference, greatly reducing the false alarm rate, while the use of low-power design is ideal for oil and gas pipelines sites and valves intrusion detection requirements. The practical application shows that the multi-dimensional three-Kam detection technology greatly reduces the false alarm rate, saving a lot of investment and has a good application function.
