Two main aspects are involved in the paper . firstly , by the research on the digital signal processing , the digital signal processing program of vibration fault analysis for rotor system is developed 本文主要進行了三方面工作:第一,對數字信號處理技術進行了研究,編制了轉子系統振動故障的數據分析程序模塊。
Next , introduct the technology of the protocol analysis . it means when examin the data packet , wo can use the protocol analysis technology to distinguish the protocol type of the data , then use the corresponding data analysis procedure to examin the data packet . so the examination efficiency can improved . finally , the k - r algorithm used for system data analysis module is parallelized design . and through the comparision the original algorithm and parallel algorithm , we can find that under the 即在對截獲的數據包進行檢測時,先使用協議分析的技術辨別數據包的協議類型,再使用相應的數據分析程序來檢測數據包,從而提高了系統的檢測效率; 5 )對系統數據分析模塊中使用的k - r模式匹配算法進行了并行化設計,并比較了原算法和并行算法的時間復雜度和執行代價。
