The catv charge and control system is mainly composed of the management software 、 the header data modulator and the terminal charge and control equipment. i am responsible for design catv charge and control equipment and test system. the header data modulator is used to encrypt the control single from computer and transmit it into the appointed frequency. the terminal charge and control equipment demodulate out the control single from data modulator and transmit it to the addressing control part, where the demodulated fsk single is received and well - handled by the cpu unit, decode the unauthorized signals and deliver it to the shut point, shut point make use of capability of wideband anf characteristic of shut, then the signal of illegal customer will be turn off and vice versa, the legal customer can receive the normal signal
前端數據調制器完成對計算機輸出的控制信號加密處理,將指令碼載送到一指定頻率點。終端收費控制器解調出控制信號,送至單片機尋址控制部分。單片機尋址控制部分接收經fsk數據解調器送來的信號,送入cpu單元后,解出不授權信號,然後向關斷部分送入信號,關斷部分利用pin二極體的寬帶工作能力以及關斷特性,實現對非授權用戶或者非法用戶的信號關斷,使之不能正常收視,繳費用戶進行開通正常收視,達到控制用戶通道的管理。In order to make the studying about the seismic exploration method possess systematic nature and the ability of tackling key problem in front - zone of mountain, we have done the research work of tackling key problem aiming at the field gathering technology of seismic exploration of the complicated structure belt ( the construction of underground and the earth ' s surface condition are complicated ) of front - zone of mountain in this text, and a large number of relativity trials by the close combination of production and scientific research, summarized a set of field method of the complicated structure belt of front - zone of mountain, adjusted both of trial factor and construction factor of the field gathering in time, achieved finally the goal of making its structure character clear
近幾年來,隨著地震勘探裝備和技術的改進,野外資料採集技術有了新的進展,主要表現為多種震源聯合激發方法(井炮和大噸位可控震源) ,基於地表條件及表層調查基礎上的激發選點方法,小道距、長排列、高覆蓋接收方法,基於模型的「分段、分線、分區」觀測系統目標設計方法等,取得了顯著的勘探效果。為了使山前地震勘探方法研究具有系統性和攻關性,通過本文對復雜山前復雜構造帶地震勘探的野外採集技術進行攻關研究,進行了大量具有針對性的試驗,總結出了一套山前復雜構造帶野外施工方法,最終達到了搞清復雜山前復雜構造帶山前復雜構造帶構造特徵的目的。In hardware design, an integrated multi - center a / d chip is for input signal conversion, cpld and arm empu are the core of fault diagnosis system and information processing. host computer is connected with the system through network technology - which owns certain advantages such as wide range of input signal, powerful processing ability and low power consumption ; also it can be extended as a remote portable terminal
在硬體設計上,採用集成多通道a / d轉換晶元完成輸入信號的轉換,使用大規模可編程邏輯器件和高性能嵌入式處理器作為故障診斷系統控制和信息處理的核心,採用網路技術實現診斷系統與主機的連接,系統具有前端輸入信號范圍寬,處理能力強,功耗低,可擴展為遠程診斷系統便攜式終端等優點。The priority controls the order in which competing clients connect to a given endpoint ; higher priority channels connect before lower priority channels
優先級控制相互競爭的客戶端連接到給定終結點的順序;高優先級通道先於低優先級通道獲得連接。The design combines the advantages of hardware " s high - speed and software ' s low resources : 1 ) mc145572 is chosen to access the net providing 128kbit / s, 2b + d full dual channels ; 2 ) because of b channel " s large amount of user data and its high demands of real - time performance, the gsc hardware channel of intel 80c152 used as cup of the system is used to wrap / unwrap b channel " s sdlc, ensuring the system real - time working
第一,選用motorola的mc145572晶元來實現終端在u節點的n ? isdn的物理接入。提供2b + d通道的全雙工的數字通信,速率達128kbps 。第二, b通道承載數據量大,實時性要求高,採用intel80c152作為cpu ,利用其gsc硬體通道實現b通道數據的sdlc (同步數據鏈路)裝幀與解幀,以確保通信的實時性。Secondly, optical nodes usually do not possess the ability of wavelength interchange for the restriction of cost and technology, optical network brings out so - called wavelength continuity constraint because connection must be established on the path that be carried by the same wavelength between source and destination nodes
再者,波長轉換技術和成本限制使得網路節點一般沒有波長轉換能力,源目的節點間的通信連接必須始終承載在同一波長通道上,產生了所謂的波長連續性限制。The paper also explains the methods to solve the technical problems, such as : the communication mechanism between home integrated services terminals and head devices, how to receive and show the dvb - c digital tv programs, how to deal with all kinds of multimedia data stream services, and so on
