4. through using the concept of logic balance, a high performance telecommunication switch network test chip is accomplished by using xilinx virtex 300e - 6 and the working clock frequency is up to 125mhz. this chip can give an exact test for the network delay time, throughput, network delay time dither, rate of errors and lost data
4 ）結合邏輯平衡的思想，採用xilinxvirtex300e - 6器件，為一家著名的通訊技術有限公司設計了速度達125mhz的交換網測試晶元，能夠對交換網的吞吐率，網路延時，網路延時抖動，數據包錯誤率，包丟失率等進行嚴格的測試，並根據當前網路的流量大小自動調節網路負載。But, the alarm signals from scada have disadvantages as follows : ( 1 ) the open - air feeder terminal units ( ftu ) are interfered by strong electromagnetic and thunder. besides, the failure of relays and the fault of ftu can also lead to that fault information is interfered and aberrant. ( 2 ) in the process of transmission and commutation, the error in the communication equipment may result in the signals err or lose
然而，現有的scada系統在配電網發生故障時提供給調度員的警報信息有如下局限性： （ 1 ）面向現場的戶外饋線終端ftu運行環境惡劣，承受強的電磁、雷電干擾，並且由於繼電器節點故障、 ftu元器件損壞等因素的存在，使得配電網信息受干擾、畸變的可能性較高； （ 2 ）在信號傳輸及變換過程中，通訊裝置的故障等原因，也可能導致信號出錯甚至丟失； （ 3 ）保護裝置和斷路器本身也有可能誤動或拒動。The contributions of this dissertation is listed below. aiming at existing defects of traditional beeline detection by hough transformation ( ht ) arithmetic, such as large storage space consuming, imprecise beeline detection effect and information loss of image feature pixels etc, we suggest two new beeline detection methods. ( 1 ) based on infinite symmetry exponential filter and its recursion arithmetic, new beeline detection methods can get exact direction of image edge pixels in advance, so it reduces highly the calculation quantity of the conventional ht, and improves the speed and the precision of beeline detection greatly
本論文的主要研究成果列舉如下：針對傳統直線檢測霍夫變換（ houghtransform ， ht ）所存在的參數空間存儲量大，直線檢測不精確以及圖像特徵點信息丟失等缺點，提出兩種新的直線段檢測演算法： （ 1 ）提出一種基於無限對稱指數濾波的ht直線段檢測演算法，在進行邊緣檢測的同時，提前精確定位邊緣點的方向，減少了ht的運算量，提高了運算速度和檢測精度，而且整體演算法便於硬體的并行執行，使得實時處理成為可能。Transmissions of real - time video always have packets loss by bandwidth limited in internet network
摘要多媒體在因特網路中實時傳播，常因網路的帶寬限製造成傳輸過程中數據包丟失。Abstract : in a network system, overflow or overwrite of message buffer will cause missing of messages. for a timed token network, message transmission time and the message buffering space allocation in a node are very important issues on network real time capability. this paper analyses the message buffering mechanism, describes the relationship of message buffering space and message transmission bandwidth allocation, and proposes a space determination method of message buffer for ltpb network. the maximum space redundancy avoiding buffer overflow for “ send ” and “ receive ” buffers has been derived. it is found that the space of “ send ” and “ receive ” buffers is equal to the message size under condition that the message gap time is greater than message latency and node response time
文摘:在網路系統中，節點緩沖區內消息發生覆蓋或溢出會造成消息的丟失，對于限時令牌網路，節點消息發送時間和消息緩沖容量的分配是影響消息實時性的重要因素.針對令牌傳遞網路分析了節點消息緩沖機制，說明了消息緩沖容量的確定與網路帶寬分配方法的關系，並提出了消息緩沖容量的確定方法，導出了避免消息覆蓋或溢出所需的最大發送和接收緩沖容量余度.指出在消息的產生間隔大於該消息的最大允許的延遲時間和接收節點響應時間的條件下，發送和接收端的消息緩沖容量等於被緩沖消息的長度In a network system, overflow or overwrite of message buffer will cause missing of messages. for a timed token network, message transmission time and the message buffering space allocation in a node are very important issues on network real time capability. this paper analyses the message buffering mechanism, describes the relationship of message buffering space and message transmission bandwidth allocation, and proposes a space determination method of message buffer for ltpb network. the maximum space redundancy avoiding buffer overflow for “ send ” and “ receive ” buffers has been derived. it is found that the space of “ send ” and “ receive ” buffers is equal to the message size under condition that the message gap time is greater than message latency and node response time
在網路系統中，節點緩沖區內消息發生覆蓋或溢出會造成消息的丟失，對于限時令牌網路，節點消息發送時間和消息緩沖容量的分配是影響消息實時性的重要因素.針對令牌傳遞網路分析了節點消息緩沖機制，說明了消息緩沖容量的確定與網路帶寬分配方法的關系，並提出了消息緩沖容量的確定方法，導出了避免消息覆蓋或溢出所需的最大發送和接收緩沖容量余度.指出在消息的產生間隔大於該消息的最大允許的延遲時間和接收節點響應時間的條件下，發送和接收端的消息緩沖容量等於被緩沖消息的長度In contrast with data communications, which are not usually subject to strict delay constraints and can therefore be handled using network protocols that uses retransmission to ensure error - free delivery, real - time video is delay sensitive and cannot easily make use of retransmission
與普通的數據傳輸不同，視頻通信受嚴格的延時限制，不能通過重傳機制保證無差錯的傳輸。預測和可變長編碼的使用也使得碼流對誤碼或數據包丟失更加敏感。分享友人
