首次採用平板顯示專用控制晶元al300 ，設計並製作了相關配套電路，支持的最高解析度是1280 1024 ，實現解隔行和多種視頻格式轉換的功能，滿足了fed顯示屏對vga解析度的要求。首次在基於fpga的vga級彩色fed控制系統中設計並製作了vga介面和分離電視信號s - video介面，可以將多種視頻信號變換為fed驅動系統可用的24位彩色數字圖像信號，實現亮度信號和色差信號的分離，提高了亮度信號的帶寬。Some stiffness matrices of special elements such as rubber bearings and components with field are derived from primary - secondary and inverse transform in structural matrix analysis. then, seismic response analytical models and non - isolated continuous rigid frame bridges are set up, while considering the interaction of soil - pile - structure and traveling wave effect simultaneously. finally, the seismic time history response of the two models is calculated by means of the finite element method, and the results show that the isolated bridge posses powerful earthquake resistance
首先論述了公路大跨徑橋梁的地震反應分析方法，其中包括樁-土-結構相互作用、行波效應等因素對結構物的影響；其次，利用結構矩陣分析中的主從變換和逆步變換，推演了幾個特殊單元的剛度矩陣，包括橡膠隔震層單元和帶剛域構件單元；最後，考慮樁-土-結構相互作用和行波效應的結合，分別建立隔震與非隔震連續剛構橋地震反應分析模型，通過有限元法對兩種結構進行時程分析，結果表明：隔震層上部結構的地震加速度反應、位移反應均明顯減小，這說明隔震的連續剛構橋具有很好的抗震能力。This design for high - speed data acquisition card with optical - electrical isolation on pci bus considers from these two respects : first, can solve the speed bottleneck problem in data transmission by fully utilizing high - speed transmission rate of pci bus ; second, can raise the electric isolation characteristics of the whole system by adding optical - electrical isolation circuit on the circuit board, and then raise the precision of measurement of the whole system
本次設計的帶光電隔離的高速pci數據採集卡就是從這兩方面考慮的：一是可以充分利用pci總線高速傳輸，解決了數據傳輸中的速度瓶頸問題；二是電路板上帶光電隔離可以提高整個系統的電氣隔離特性，進而提高整個系統的測量精度。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
