The essay combines the power system prediction , mathematical build modular technology and computer technology together and thoroughly and systematically makes an analysis , thus the software functions designed can meet the needs of power system load prediction 論文將電力系統(tǒng)負(fù)荷預(yù)測分析、數(shù)學(xué)建模技術(shù)、計(jì)算機(jī)技術(shù)有機(jī)結(jié)合,進(jìn)行了深入、系統(tǒng)地分析。所設(shè)計(jì)的軟件功能較好地滿足了電力系統(tǒng)負(fù)荷預(yù)測的需求。
When discussing problems , classifying software functions and modules , telecom operators and software developers all start with customer management , business management and network and equipment management from the perspective of implementation , protection and billing 電信運(yùn)營商和軟件開發(fā)商在論述問題、劃分軟件功能和模塊時(shí),都從實(shí)施、保障、計(jì)費(fèi)三個(gè)方面,客戶管理、業(yè)務(wù)管理、網(wǎng)絡(luò)和設(shè)備管理三個(gè)層次入手。
Dividing the evaluation of network - nle system into four subjects : video quality unit , network bandwidth unit , software function unit and system stability unit . thus , the evaluating and testing method has been developed based on further standardization and specification 嘗試將非編網(wǎng)絡(luò)測試分為視頻質(zhì)量單元、網(wǎng)絡(luò)帶寬單元、軟件功能單元、系統(tǒng)穩(wěn)定性單元等四個(gè)項(xiàng)目,并進(jìn)行了規(guī)范化和細(xì)化,提出了改進(jìn)的測試評估方法。
The hardware composes of several parts such as human - machine interface , analog - to - digital converter , memory interface , digital control power . the software functions as data collection , disposal and output . the system has characteristics of speediness , high precision and automatism 硬件系統(tǒng)是以tms320c31為核心的電路,主要包括人機(jī)接口部分、模數(shù)轉(zhuǎn)換器部分、存儲(chǔ)器接口部分、數(shù)控恒流源等,軟件主要實(shí)現(xiàn)數(shù)據(jù)采集、處理和數(shù)據(jù)輸出等功能。
Thirds , based on need analysis , this system adopts browser / server structural " three layer model " , uses application development policy based on component , combines database techniques , web and database link with each other techniques , puts forward a project , discusses system " s software function module . . . . . . 然后,在需求分析的基礎(chǔ)上,系統(tǒng)采用browser server結(jié)構(gòu)的“三層模型” ,使用基于組件的應(yīng)用開發(fā)策略,綜合了數(shù)據(jù)庫技術(shù)、 web與數(shù)據(jù)庫互連技術(shù),提出了一個(gè)設(shè)計(jì)方案,詳細(xì)討論了系統(tǒng)的軟件功能模塊等。
But on the other hand , with the continuous improvement of the computing power and the growth of people ' s demand of the software function , the software product becomes huger and huger , there are more and more uncertain factors in the software development course , construction cycle and the risk of development are difficult to control . all of these are restricting the development of large - scale software 但另一方面,隨著計(jì)算機(jī)性能的不斷提高,以及人們對軟件功能需求的增長,軟件產(chǎn)品變得越來越龐大,軟件開發(fā)過程中的不確定因素越來越多,開發(fā)周期、開發(fā)風(fēng)險(xiǎn)難以控制,這一切,都制約著大型軟件的開發(fā)。
