Electricity metering - data exchange for meter reading , tariff and load control - part 42 : physical layer services and procedures for connection - oriented asynchronous data exchange 電量測量.計數(shù)器讀數(shù)電費和負(fù)載控制的數(shù)據(jù)交換.第42部分:定向連接異步數(shù)據(jù)交換的物理層工作和程序
It uses asynchronous data transfer ( http requests ) between the browser and the web server , allowing web pages to request small bits of information from the server instead of whole pages 在瀏覽器和服務(wù)器之間,它使用異步數(shù)據(jù)進行轉(zhuǎn)換,并允許網(wǎng)頁向服務(wù)器索取少量信息而非整個網(wǎng)頁。
Asynchronous data synchronization lets a sql server 2005 mobile edition sql server mobile application to continue processing other information while waiting for data synchronization to complete 異步數(shù)據(jù)同步使sql server 2005 mobile edition ( sql server mobile )應(yīng)用程序在等待數(shù)據(jù)同步完成的同時能夠繼續(xù)處理其他信息。
A new algorithm of two - terminal fault location using asynchronous data at both ends is used in the device , which use the data pre - fault to remove the angular difference caused by the asynchrony of the two terminals 分析比較了現(xiàn)有的各類測距算法,給出了一種新的不需要數(shù)據(jù)同步的雙端測距算法,利用故障前數(shù)據(jù)校正故障后兩端數(shù)據(jù)的不同步角差。
Electrical parameter gathering is an indispensable part of ecs . in the thesis , the technology of serial asynchronous data communication is applied to the electrical parameter gathering system and a satisfactory result is obtained 電量參數(shù)采集是電控系統(tǒng)的重要組成部分,本文將串行異步數(shù)據(jù)通訊技術(shù)應(yīng)用于風(fēng)電機組的電量采集系統(tǒng),并收到了較為滿意的效果。
In the main body of this paper , the database design process is introduced , in which the database relation schema , data integrity and fault recovery are emphasized , and , the communication protocol designed for remote data acquisition is discribed and validated by petri nets , the develop method of client application and resolvent to some problems are also discussed , including the design of communication component , the asynchronous data return , how to dynamically return image to the client navigator in web application etc . finally , an abbreviated evaluation about the finished system is given 在論文的主體部分,論文詳細(xì)介紹了數(shù)據(jù)庫的設(shè)計過程,其中主要涉及到關(guān)系模式的規(guī)范化、數(shù)據(jù)完整性和故障恢復(fù)設(shè)計等,隨后,文章設(shè)計了一種用于遠(yuǎn)程數(shù)據(jù)采集的通信協(xié)議,并使用petri網(wǎng)進行了描述和驗證,論文也介紹了如何進行客戶端應(yīng)用程序的開發(fā)以及一些主要問題的解決,主要包括通信控件的設(shè)計、采集數(shù)據(jù)的異步返回、在web應(yīng)用程序中如何動態(tài)為客戶端返回圖形等。最后,論文對整個系統(tǒng)做了一個簡單的評估。
Based on the comprehensive analysis of the application status and the existed problems of transmission line fault location , this dissertation presented a new algorithm for fault location based on two - terminal asynchronous data , which can make correction for the integrate error of line parameter , length of transmission line , sampling value and so on . at the same time , it can work out the two - terminal asynchronous phase angle with the corrected parameters 本論文在充分分析了國內(nèi)外故障測距的理論與技術(shù)以及存在的問題后,針對輸電線路故障定位因線路參數(shù)變化對定位準(zhǔn)確度的影響,提出了能夠?qū)€路的參數(shù)、長度和采樣值等誤差等進行綜合誤差修正( cie )的新算法,并利用修正后的參數(shù)來求解兩端的不同步相角差。
