中文摘要 |
台灣四面環海,海洋運輸因此成為台灣重要的經濟命脈。有鑑於此,本文研究一透過雲端運算與分散式儲存的系統,可用於收集散佈於海面上的監測感 應器所提供的大量資料進行運算、分析,進而判斷是否有會造成磁場異常擾動的帶磁性入侵物出現與其所在方位與運動方向的辨識。 我們利用Apache基金會所提供的Hadoop平台進行可分散處理的K-Means分群運算、收集搭載磁場感應器與DGPS定位裝置的海面感應器節點所獲得的資料,並判斷入侵物的有無與可能的移動方向,並將此結果回傳到遠端的監控終端。除了K-Means分群演算法相當適合處理磁場異常的偵測以外、本系統也透過Hadoop平台獲得優秀的可靠性與效率。 |
Abstract |
Taiwan is surrounded by ocean, thus the ocean transportation has become the necessary support of Taiwan's economy. Due to this fact, this research provides a system based on cloud computing and distributed storage which is applied to compute large amount of data provided by many sensors on the sea in order to diagnose the existence of possible magnetized invaders. We use Hadoop platform from Apache Foundation to proceed distributable K-means clustering computation to process the data collected f rom many sensor nodes containing DGPS and magnetic sensors. With these data, it is possible to diagnose the existence and the moving direction of the possible invader. And the result can be return to remote monitoring terminal. Not only K-means can detect the irregularity of any axis of the magnetic field well, but also this system obtain good reliability and performance by Hadoop platform. The goal system can detect the irregularity of any axis of the magnetic field well enough by deploying K-Means clustering and obtain good reliability and performance by Hadoop platform. |
