The development of fieldbus technology made lonworks field bus outstanding in all kinds of fieldbus. this paper simply introduces some kinds of common using fieldbus and the important position and influence of lonworks fieldbus in all kinds of fieldbus, carefully describes the technology core of lonworks technology, puts great emphasis on the introduction of the development and design of public security node of intelligent district which adopts computer, communication and control technology, carefully designs the interfaces of hardware circuits. the public security node of intelligent adopts 8031 single chip as its main processor to complete the application program of user, which mainly collects, process and control all kinds of field signal, and neuron chip 3150 as its slave processor to communicate with other nodes on field network, which works under parrel slave a mode
現場總線技術的發展使得lonworks技術脫穎而出，本文簡要介紹了常用的幾種現場總線的概況以及lonworks技術在現場總線技術中的地位和影響，對lonworks技術的技術核心：神經元晶元、 lontalk協議、 lonworks收發器、 lonbuilder及nodebuilder進行詳盡的描述；重點介紹了集先進的計算機技術、通信技術、控制技術為一體的智能小區安防節點的開發與研製，對節點硬體電路的各種介面進行了詳盡的設計。本文設計的智能小區安防節點採用單片機8031作為主處理器來完成用戶的應用程序，主要負責對各種現場信號進行採集、處理及控制，工作在并行從a方式下的神經元晶元mc3150作為從處理器，主要完成與現場網路上的各節點及中心控制室之間的通信工作。At present, the most of vtr which are used in watch - control occasion for speciality are short of a uniform control - check - alarm system, which brings on the discommodiousness of operation and the user can not know the time of occurring a fault, which reduces the reliability of the watch - control system. therefor, at first, i carefully analyze the servo theory of the vtr which had been produced by chmavc with k mechanism to find out the work rule of the control signal ; second, take out some right control signal ; then for dealing with the problem of vtr in use for watch - control, i choose some right components to design the uniform control system for many special vtr with protel software. it mainly includes the following functions : operation functions of all vtr ( for example : power, play, ff, rew, stop, rec, eject, fwd, rwd, sp, lp ) was controlled by line at the same time ; in, the process of recording, when the tape walks to the end or stops by itself, the system gives an alarm and shows the number of the wrong vtr ; in the process of recording, the system gives an alarm and shows the number of the wrong vtr when the video signal from vidicon is losed ; the system controls all vtr to record on the non - working time when there is something wrong in the guarding section ; the system controls the video from vtr to switch to right monitor
目前，用在監控場合的業務用錄像機普遍缺乏一個統一的控制及檢測報警系統，這就導致了操作的不方便和出現了故障用戶不知道，降低了監控系統的可靠性，為此，我首先對華錄松下生產的k機芯的錄像機伺服原理進行仔細分析，找出各個伺服控制信號的控制變化規律；然後從中選出合適的控制信號；針對目前錄像機在實際監控使用過程中存在的問題，選用合適的元器件；運用protel繪圖軟體，設計了這個多臺業務用錄像機的統一控制系統，她主要包括以下功能：錄像機操作功能（如power play ff rew stop rec eject及正尋反尋帶速設定等）的統一線控控制功能；磁帶在記錄過程中，磁帶到頭和磁帶自己「偷停」的報警，並要能顯示出具體是哪一臺錄像機；在記錄狀態下，攝像頭輸入信號丟失報警，並要能顯示出具體是哪一臺錄像機；在休息或其他不需要記錄時，一旦警戒區有情況，則控制所有機器自動進入錄像狀態的功能；從錄像機輸出的監控圖像信號對監視器的切換功能。Wyndsor hotel in shenzhen nanshan district commercial, cultural, entertainment center - new south road 33, shennan avenue, binhai avenue, sea, land and air transport facilities, airports, shekou port, the first of the south, guang - shen, a shopping center near rainbow, near shekou industrial zone, baoan industrial zones, technology parks, overseas chinese town ; beautiful china, folk village, the world window, huanlegu, green world, wild zoo, the hotel is at the shenzhen industrial and commercial bank of china and citic bank, china merchants bank to merchants, providing you the best in leisure activities as well

討論了該類噴管的流場特徵、組分分佈特點、總壓損失特徵、反應區流場參數和反應流混合機理，並對小信號增益系數、 f原子利用效率和反應放熱進行了計算。In this dissertation, an intelligent analyzer based on image processing technology is developed for cashmere fiber quality inspection. the setup of the intelligent analyzer includes a personal computer, a image capturing card, an optical microscope, a ccd camera, a x - y driving worktable, a printer and a set of software for image capturing and analyzing. microscopic images are captured by the ccd camera and are saved in the hard disk in digital form
系統的分析過程為：待測量纖維經顯微鏡成象后，由ccd將光信號轉換成電信號，再經圖象卡將顯微視場中的一塊區域轉化成一幅數字圖象，然後用計算機對數字化纖維圖象做分割處理（即二值化處理） ，找出待分析的纖維，通過快速纖維檢測演算法進行分析計算，測定各纖維組分的平均直徑和根數等主要參數，從而計算出各纖維組分的含量。The purpose of reforming the foreign exchange institute is to increase the elasticity of the system, and from this, exchange rate can have the function of regulating the economy. the media measure is improving the forming mechanism of exchange rate of rmb. at present, the feasible measures is enlarging the floating region of exchange rate of rmb. firstly, improving the extent of marketization of forming mechanism of exchange rate, including enlarging the floating region of exchange rate of rmb in the inter - bank exchange market, adjusting the policy of exchange position of banks, reforming compulsive exchange settling institute
今後，我國有必要改進人民幣有管理的浮動匯率制度，使匯率更多的反映市場供求信號。完善人民幣有管理的浮動匯率制度的最終目的，應是改進人民幣匯率形成機制，增加人民幣匯率制度的彈性，以進一步發揮匯率杠桿對經濟的調節作用。當前可以選擇的政策措施是擴大人民幣匯率的波動區間。This paper particularly compares the complexities of the three manners ? the base band complex signal manner 、 the intermediate frequency complex signal manner and the intermediate frequency real signal manner, in the rf circuit and the base band digital signal processing, respectively ; chooses the intermediate frequency complex signal output manner, which not only reduces the complexity of the digital signal processing, but also be compatible with the intermediate frequency real signal output manner in some applications which have strictly request on the consistency of the amplitude and the phase in i / q channels
然而在以往的文獻中很少對此進行過全面的分析。論文詳細比較了三種不同的信號輸出方式? ?基帶復信號、中頻復信號和中頻實信號在rf電路和後端數字信號處理復雜度上的區別;並為接收機選擇了中頻復信號輸出方式，在降低數字信號處理復雜度的同時，還能在某些對i / q雙通道幅相一致性要求嚴格的應用場合兼容中頻實信號輸出方式。分享友人
