This is a computerised voice communication system between pilots and air traffic controllers, and between air traffic control positions in the air traffic control centre, aerodrome control tower, rescue coordination centre and aeromobile centre by using pre - set switching and distribution of various aeronautical frequencies and direct communication lines. the new computerised system will enhance the overall efficiency in communications
讓機師與管制員之間,或航空交通管制中心、指揮塔、援救協調中心和航空通訊中心內各不同管制崗位之間,能用預先設定的系統作直接通話,包括可轉換和發布的航空通訊頻道和直接通訊線路等。At the same time the effection of some important recombinations are discussed and the relation of photoconduction versus time is given. in chapter 4, auston circuit, blumlein pulse forming line, multiplier of pulse forming line are introduced and give their differentiates
在第四章中,分析各種以光導開關為核心器件的電脈沖成形電路: auston電路、 blumlein脈沖成形線、層疊線倍壓器,對其輸出轉換效率進行比較,並進行實驗研究。To avoid the serious electromagnetic interferer, the analog signals are transformed to frequency pulses which are transferred to the kernel of the system. in the measure of the groove voltage, the method of float - ground is adopted to avoid the high common signal and the range switch circuit is designed to solve the conflict of the wide dynamic range and the high precision. least square curvefit is adopted to reduce the system error
鋁電解生產現場電磁干擾非常嚴重,為此我們將需要測量的模擬信號就近轉換為頻率脈沖后再傳送到控制核心;採用浮地接入方式消除槽電壓信號中的共模成分;設計了量程自動切換電路以解決槽電壓的動態范圍寬和測量精度高的矛盾;用最小二乘法進行曲線擬和以降低測量的系統誤差。The new algorithm starts from an initial estimate which is based on the hough transform, and a rectangular window is centered using the current line approximation, and a new line estimation is generated by making a total least squares fit through the pixels contained within the window. this is repeated until convergence is reached. lastly, we have suggested a new technique which may recover the motion and structure parameters of a moving object by using of 21 optical flow lines based on the optical flow fields of the feature line this thesis is the project supported by aeronautical foundation science ( no. 99f53065 ) and research center of measuring and testing technologies, and control engineering in nanchang institute of aeronautical technology ( no. 2001 - 15 )
演算法的思路是:首先,在小區域內運用霍夫變換確定直線的初始值;其次,以直線的初始值所對應的直線為中心線,建立一個矩形框;最後,利用矩形框內所包含的邊緣點數據不斷地迭代直至收斂,從而達到進一步修正直線的坐標參數;本文基於特徵直線的光流場,即線流場,建立了一種利用21條光流線確定空間三維物體旋轉運動參數、平移運動參數以及對應的空間直線坐標的線性演算法。His idea is based on the fact that the pivot of the soft wireless structure is to put the broad band a / d and d / a conversion near to antenna by all means, and to define the functions of the transmitter - receiver as many as possible in the forms of software ( namely realized by software ). the technology of background signal simulator puts the focus on the methods used to realize the software, namely to exploit the functions of the hardware ( for example, dsp fpga or asic ) through the idea of software design, and to produce ( realize ) wireless signals by high speed lsi and software programming
1992年5月的全美電信系統年會上, mitre公司的資深科學家joemitola首次給出了軟體無線電的定義,他認為:軟體無線電的組成架構的中心點是將寬帶模?數( a d )和數?模( d a )轉換器盡可能地靠近天線,將盡可能多的電臺功能以軟體的形式定義(即用軟體來實現) 。背景信號模擬器所採用的技術集中體現在軟體無線電技術,即用軟體化設計去開發硬體(如dsp 、 fpga 、 asic )功能,採用高速大規模數字集成電路、軟體編程的方法產生(實現)各種無線電信號。This image grab card uses saa7111 to translate the analogue signal to digital image data. after buffering in an fifo ram the data are read into computer by a universal pci interface chip, pci9052. finally the images are displayed on screen
該視頻採集卡以fpga為邏輯控制中心,採用saa7111將四路視頻信號分別轉換為數字圖像數據,經fifo緩存后,由pci總線介面晶元pci9052將數據送入計算機,最後通過應用程序將圖像顯示出來。分享友人
