  2. 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。
  3. Keyboard, video, mouse switch. it is a hardware device that enables a single keyboard, video monitor and mouse to control more than one computer one at a time

    鍵盤、視頻、鼠標轉換器。允許單個鍵盤，視頻監視器和鼠標同時控制多臺電腦的硬體設備。
  4. As to the video signal, alarm signal, control signal, are all weak electricity signal, exceedingly easily be subjected to the jam, in case the power supply system does not steady, wave propag ation is greatly, the harmonic content of power source overtops, the veins wave factors are great unduly, and even power source equipment breakdown, outputting abnormal, will be about to affect the video signal image effect, and dependability cuts downs to the security and alarming system. we adopt fast fu lye ' s mutation rule - fft alternatives, by the way of carrying fft alternatives to the local junction circuit, regulated power supply, ups ' s power source, and switch power source, thereby diagnose every degree harmonious wave content of power souse, and abnormal coefficient, compared to the normal working situation. thereby diagnose out the working condition of the regulated power supply, ups ' s power source, and switch power source

    如果有供電系統不穩定、波動大，電源的諧波含量過高，紋波系數過大，乃至電源設備損壞、輸出異常等情況出現，將會嚴重影響視頻信號的圖像效果，大大降低防盜系統的穩定性和可靠性，我們採用快速傅利葉變換原理，即fft變換，通過對市電、穩壓電源、 ups電源、開關電源等的電壓信號進行fft變換，從而得出信號中各次諧波的含量及信號畸變系數，並將其與正常工況下的參數進行對比，從而進一步診斷出穩壓電源、 ups電源、開關電源等設備的運行狀況；組成監控系統的設備長期處于工作狀態，往往由於設備散熱條件不好、設備老化故障等原因導致設備表面溫度過高，從而影響設備的正常運行，降低設備的使用壽命。
  5. It ’ s a 16 / 32bits risc cpu based on arm920t ip core, which is highly integrated and powerful. this cpu has a lot of peripheral interfaces and i / o ports, which will facilitate our system design. the asic ime6400 is a system level chip which supports the multi - channel mepg4 video / audio compression. in our design, it ’ s served as an video compression oriented co - processor working under the control of s3c2410x. s3c2410x will do the job of importing the other vehicle traveling data such as analog and switch signals

    在筆者設計的系統中， ime6400作為專門進行數字視頻信號壓縮的協處理器，與s3c2410x協同工作，完成視頻信號的獲取，壓縮等工作;同時利用晶元的片內外設（如ad轉換器和i / o口） ，完成汽車行駛過程中開關量和模擬量的獲取和存儲，以滿足一個記錄儀的基本功能需求。
  6. After finishing multimedia player function, i bring forward the scheme in control of video signal switch through gpio pins in ep9315

    基本實現了多媒體模塊的視頻播放功能，在此基礎上提出了通過ep9315上的gpio口控制混合電路模塊的視頻信號切換功能方案。
