改进的Kalman滤波器在输油管道泄漏监测中的应用

Applying of Reformative Kalman Filter in Oil Conveying Pipeline’s Leakage Supervising

应用改进的Kalman滤波器对采得的输油管道原始压力数据进行实时性滤波,以消除噪声干扰、提高信噪比;利用滤波后的信号进行输油管道泄漏的报警和定位。数据仿真和工程检测实际应用表明,改进的Kalman滤波器可大大提高输油管道泄漏报警的可靠性及其定位精度。

This paper uses the reformative Kalman filter to deal with the original pressure data sampling from oil conveying pipeline in real time to eliminate the noise interference and to improve the signal noise ratio.It also uses the signal after being filtered to give an alarm and exact position of the leakage of oil conveying pipeline.The emulation and engineering applying shows that the reformative Kalman filter designed by this paper can largely improve the alarming reliability and orientation precision of oil conveying pipeline.
