1. The first part of the paper is designing the testing project for grounding resistance and insulation resistance in a new way . using 16bits ad converter with programmable control amplifier replaced the way which used changing resistance to change measure range . lt is not only improved testing precision and develop the system expediently , but also reduced the area of the circuit boardwith the new way . in order to make the electric implement safety testing system have upstanding expansibility , the software and hardware of the system adopted the modularization design . adopted mcu atmegal28 as a master mcu which control mmi , realtime clock and communication with slaver mcu . atemga8 as the slaver mcu to realize testing function . so it is easy to add or reduce the testing project . the testing implement system has been developed successfully , and the comments for the system is that it has high precision , high expansibility and easy maintain . but considering the electric implement system should have intelligence and humanity abi lity . so this paper bring forward a scheme of electric equipment safety testing embedded system with speech control . after introduce the basic theory of speech recognition , the paper expatiate the characters of this system . the system is a noise conditon , not special people , small glossary , insulation word system . with these characters design the speech recognition as fellow . utilizing cross zero ratio and short energy to ensure jumping - off point and end point ; adopting mfcc as the character parameters of speech recognition ; the character parameters than be recognized by dtw . in order to ensure the credibility of this project , first realized by matlab in computer
   在介紹了語(yǔ)音識(shí)別的基本原理后，闡述了本系統(tǒng)的特點(diǎn)：本系統(tǒng)是一個(gè)噪聲環(huán)境下非特定人、小詞匯量、孤立詞的語(yǔ)音識(shí)別系統(tǒng)。根據(jù)本系統(tǒng)的這些特點(diǎn)設(shè)計(jì)了如下語(yǔ)音識(shí)別方案：利用過(guò)零率和短時(shí)能量相結(jié)合的方式確定語(yǔ)音端點(diǎn)；采用mel頻率倒譜系數(shù)( mfcc )作為語(yǔ)音識(shí)別的特征參數(shù)；得到的特征參數(shù)最后通過(guò)動(dòng)態(tài)時(shí)間規(guī)整( dtw )的模式識(shí)別方法進(jìn)行識(shí)別。為了確保本系統(tǒng)實(shí)現(xiàn)方案的可靠性，首先通過(guò)計(jì)算機(jī)利用matlab軟件來(lái)仿真，在算法仿真實(shí)現(xiàn)后又進(jìn)一步增加環(huán)境的復(fù)雜性：加上較大的環(huán)境噪聲、突發(fā)性的噪聲等，再通過(guò)修改參數(shù)、修改參考模板、兩級(jí)識(shí)別等各種提高語(yǔ)音識(shí)別精度的方法來(lái)提廣東工業(yè)大學(xué)工學(xué)碩士學(xué)位論文高識(shí)別率。
2. It's difficult to find realtime clock in a sentence. 用realtime clock造句挺難的
