    該系統還採用美國進口原裝晶元與先進的無線數字高頻技術微電腦cpu控制器主機組成。在防範地點安裝好主機后，並設置在布防狀態。一旦有盜賊闖入防範地點，探測器立刻發射無線編碼信號，安裝在距防區150米以內的主機立即發出警笛聲報警，報警時撥打預先設定的聯網中心號碼或報警電話手機號碼，接警電話里回放用戶預錄的報警語音，遠程報警，同時通過網際網路來實時傳遞布防撤防報警等狀態，通過電腦網路來查詢歷史記錄。
  2. The system is consist of the main data processing board which is based onthe fpga device and fast ethernet phyceiver rtl8201l and a - law pcm data encoder and decorder chip msm7702 - 3, and the dial - up and display board which is based on mcu. the main board would carry out the core task of data processing, such as voice data packing and unpacking, the ethernet frame processing, protocol processing, call processing, etc. the dial - up and display board would carry out the task of display the ip address which is input by consumer and status of network during talk period from the main board, and so on. in the paper the system of lan ip telephone and the tcp / ip protocol is introduced firstly, then the fpga device is stated. after that the fpga - based hardware scheme is introduced in detail in chapter four

    系統以altera公司的acex1k系列的fpga和快速以太網控制器rtl8201l和語音編解碼晶元msm7702 - 3為核心構建了數據處理主板和以單片機為控制器的撥號顯示子板組成。數據處理主板的核心任務，包括語音數據處理、以太網幀處理、協議處理、呼叫處理等。撥號顯示子板則完成通話前的顯示用戶所撥過的ip地址，通話期間網路狀態的顯示等等。
  3. It reframes the traceback problem as a polynomial reconstruction problem, and uses techniques from algebraic coding theory to provide robust methods of transmission and restriction. the scheme is a new solution to the traceback problem during a dos attack ; the honeypot for ddos, which is a tool of traceback, lures the attacker to believe that he successfully compromised a slave for his needs, convincingly simulating the architecture of a potential ddos attack ; the source - based approach to ddos defense, which is a useful adjunt to traceback systems, deploys a ddos defense system at source - end networks. attacks are detected by monitoring two - way traffic flows, and the attacks originating from source networks are stopped by rate - limiting ; the routing mechanism based on pushback treats ddos attacks as a congestion - control problem

    最後，就有關ddos攻擊反向追蹤問題，從四個方面對其解決方案進行了研究：在分析比較幾種反向追蹤演算法的基礎上，著重研究了代數方法編碼反向追蹤信息的方案，該方案把追蹤重構問題當作多項式重構問題，使用代數編碼理論技術提供魯棒的傳送和重構方法，是dos攻擊過程中的反向追蹤問題的一種新的解決方法； ddos陷阱作為反向追蹤的工具，引誘攻擊者相信自己成功與所需的傀儡主機通話，令人信服地模擬出潛在ddos攻擊體系結構；基於源的ddos防禦方法作為反向追蹤有用的補充，將防禦系統部署在源網路，通過監控雙向流量檢測攻擊和限制速率終止來自源的攻擊；基於向後倒推的防禦ddos的路由機制把ddos攻擊看作擁塞控制問題，添加功能到每個路由器來檢測並優先丟棄可能屬于攻擊的包，通過向後倒推上級路由器也得到通知而把這樣的包丟棄。
  4. And the main focus is the design, implementation and testing of an adaptive line echo canceller and a vocoder based on multi - band excitation ( mbe ) model

    主要工作是設計並實現電話線路自適應回波抵消器和基於多帶激勵模型的語音編解碼器。
  5. Telephone communication is the most widely employed ways of communication in the world. telephone communication is becoming more and more important as the national economic reform deepens. dynamic channel borrowing assignment mode is an effective method in communication channel expansion. although it has been put into practical use in satellite communication and mobile communication, no one has attempted to apply it to telephone line expansion. in this paper the author expands the telephone line via dynamic channel borrowing assignment mode, ascertains the expansion scheme, designs the circuit of hardware in telephone line expansion device, draws up software programme, analyses the call lose after using the expansion device theoretically and then experiments to verify it. eight subscribers can share one or two telephone lines with the help of the telephone line expansion device with each phone a sole number. this makes it possible for subscribers to use any free telephone line. thus increasing the number of subscriber and utilization ration of telephone line. in addition. this project makes it possible for expansion subscribers to communicate directly while not to make use of outer line. which further decreased the system call lose

    多通道共用是通信通道擴容的一種有效的方法，已在衛星通信、移動通信中得到應用，但尚未應用到電話線路擴容中。本文利用多通道共用原理對電話線路進行擴容，確定了多通道共用方式電話線路擴容的設計研究方案，研究設計了電話線路擴容器的硬體電路，編制了電話線路擴容器的軟體，並對使用電話線路擴容器后的呼損進行了理論分析及試驗研究。本文研究設計的多通道共用方式電話線路擴容器可以使8個用戶共用1 2對電話線路，每部用戶話機都具有獨立的電話號碼，可以利用任一空閑的電話線路，故能夠增加電話用戶，提高電話線路的利用率。
