基于ZIGBEE的嵌入式自動抄表系統(tǒng)的研究.rar

近年來，近距離無線傳輸技術(shù)是發(fā)展最快、最引入注目的技術(shù)，而ZigBee恰恰是填補了低速率無線通信技術(shù)的空缺，與其他標準在應(yīng)用上相得益彰。它專注于近距離傳輸，成本低、同時入門檻也低，雖然其出現(xiàn)較晚，但目前已經(jīng)得到人們越來越多的關(guān)注，成為無線技術(shù)研究的一個新熱點。本文在詳細分析了傳統(tǒng)的抄表方式和無線抄表系統(tǒng)的發(fā)展狀況以及相關(guān)的無線數(shù)據(jù)傳輸技術(shù)的基礎(chǔ)上，提出了基于ZigBee技術(shù)的無線抄表系統(tǒng)的方案。論文在研究ZigBee組網(wǎng)技術(shù)的基礎(chǔ)上，設(shè)計了基于ZigBee開發(fā)平臺的無線嵌入式抄表系統(tǒng)，編寫了相應(yīng)的軟件，完成了相應(yīng)的調(diào)試和分析，并進行了系統(tǒng)的可靠性、實時性和安全性等問題分析。為了減少系統(tǒng)由于節(jié)點路由而造成的功耗損耗過大的問題，本文在組網(wǎng)應(yīng)用過程中采用Tree+AODVjr的路由算法，從而保持系統(tǒng)能夠保持較小功耗的情況下進行數(shù)據(jù)的多跳路由，同時以ARM S3C2410為核心實現(xiàn)了基站設(shè)計，實現(xiàn)小區(qū)電表數(shù)據(jù)的集中采集，并通過GPRS/GSM模塊實現(xiàn)基站和抄表中心的數(shù)據(jù)傳輸和實時控制，在此基礎(chǔ)上，對抄表系統(tǒng)軟件也進行了相應(yīng)的設(shè)計。通過單點對單點、星形網(wǎng)絡(luò)數(shù)據(jù)傳輸實驗，取得了相應(yīng)的實驗數(shù)據(jù)，對于協(xié)議的特點、系統(tǒng)可靠性和功耗情況有了整體把握，為今后ZigBee技術(shù)的進一步研究和應(yīng)用打下了堅實基礎(chǔ)。實驗結(jié)果顯示，本文提出的方案切實可行，并且采用ZigBee技術(shù)具有節(jié)約資源、操作方便、可靠性高而且易于管理等特點，基站和系統(tǒng)利用較為成熟的GPRS/GSM網(wǎng)絡(luò)技術(shù)進行通訊，既滿足了實時性要求，又降低了成本。

入侵檢測系統(tǒng)的網(wǎng)絡(luò)包分類技術(shù)研究

基于FPGA技術(shù)的網(wǎng)絡(luò)入侵檢測是未來的發(fā)展方向，而網(wǎng)絡(luò)包頭的分類是入侵檢測系統(tǒng)的關(guān)鍵。文章首先介紹了FPGA技術(shù)的基本原理以及其在信息安全方面的應(yīng)用，接著介紹入侵檢測系統(tǒng)以及FPGA技術(shù)在入侵檢測系統(tǒng)中的應(yīng)用。分析了幾種比較出名的網(wǎng)絡(luò)包分類算法，包括軟件分類方法、TCAM分類算法、BV算法、Tree Bitmap算法以及端口范圍分類算法。在此基礎(chǔ)上，文章設(shè)計了一個基于FPGA技術(shù)的入侵檢測系統(tǒng)包分類的基本框架圖，實現(xiàn)框架圖中的各個基本功能模塊。在實現(xiàn)過程中，提出了一類結(jié)合三態(tài)內(nèi)容可尋址內(nèi)存(TCAM)和普通存儲器(RAM)的網(wǎng)絡(luò)包包頭分類方案。我們將檢測規(guī)則編號并位圖化，使用RAM存儲與包頭結(jié)構(gòu)相關(guān)的規(guī)則位圖，通過TCAM上的數(shù)據(jù)匹配操作，快速關(guān)聯(lián)待分析的網(wǎng)絡(luò)數(shù)據(jù)包與入侵檢測規(guī)則。文章還討論了網(wǎng)包頭分類方法的優(yōu)化算法，將優(yōu)化算法與未優(yōu)化算法在速度和空間上進行比較。此外，還討論了對Snort的規(guī)則庫進行整理和規(guī)則化的問題。最后，對所設(shè)計的包頭分類匹配模塊在Quartus II進行仿真評估，將實驗結(jié)果與已有的一些分類算法進行了比較。結(jié)果說明，本設(shè)計在匹配速度和更新速度上有優(yōu)勢，但消耗了較多的存儲空間．

This scheme is initiated by Ziv and Lempel [1]. A slightly modified version is described by Storer and Szymanski [2]. An implementation using a binary tree is proposed by Bell [3]. The algorithm is quite simple: Keep a ring buffer, which initially contains "space" characters only. Read several letters from the file to the buffer. Then search the buffer for the longest string that matches the letters just read, and send its length and position in the buffer.

Contains a complete archiver by Haruhiko Okumura. The archiver uses an LZ engine whose output is compressed with static Huffman. The file is chopped into pieces which all get their own independent set of Huffman tree s. ARJ 2.41, ZIP 2.0 and PKZIP 2.04g use essentially the same method. ZOO and LHA even use excactly the same method.
