例句與用法
First , the fault type is identified by rough - set , then the neural networks determines the fault elements by the sampling voltage values . with regarding to the other method , the rough - set is looked as the pre - system of neural network . . the fault information as well as the sampling voltage values are simplified by rough - set , and the outcome of this processing is the input of neural network . 整體結(jié)合是利用粗糙集對(duì)故障信息中樣本的所有故障征兆進(jìn)行數(shù)據(jù)處理,通過知識(shí)約簡(jiǎn),刪除多余的征兆屬性,簡(jiǎn)化知識(shí)表達(dá)空間維數(shù),簡(jiǎn)化以后的樣本數(shù)據(jù)作為神經(jīng)網(wǎng)絡(luò)的訓(xùn)練樣本,構(gòu)成完整的粗糙集-神經(jīng)網(wǎng)絡(luò)故障診斷方法,將粗糙集與神經(jīng)網(wǎng)絡(luò)相結(jié)合,簡(jiǎn)化了神經(jīng)網(wǎng)絡(luò)結(jié)構(gòu),從而達(dá)到提高診斷速度的目的。
Using the high - performance digital signal processor ( dsp ) as cpu , the author designs the medium - speed sampling and processing unit of the fault locator . on the one hand , this unit can sample voltages and currents of the line synchronously ; on the other hand , this unit can start the fault locator up and select the fault lines when faults occur 本文作者還以高性能的數(shù)字信號(hào)處理器( dsp )為cpu設(shè)計(jì)了測(cè)距裝置的中速采樣處理單元,該處理單元一方面可以實(shí)現(xiàn)線路電流電壓信號(hào)的同步數(shù)據(jù)采集,另一方面可以完成測(cè)距裝置的故障啟動(dòng)和故障選線任務(wù)。
