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
在介紹了語音識別的基本原理后，闡述了本系統的特點：本系統是一個噪聲環境下非特定人、小詞匯量、孤立詞的語音識別系統。根據本系統的這些特點設計了如下語音識別方案：利用過零率和短時能量相結合的方式確定語音端點；採用mel頻率倒譜系數（ mfcc ）作為語音識別的特徵參數；得到的特徵參數最後通過動態時間規整（ dtw ）的模式識別方法進行識別。為了確保本系統實現方案的可靠性，首先通過計算機利用matlab軟體來模擬，在演算法模擬實現后又進一步增加環境的復雜性：加上較大的環境噪聲、突發性的噪聲等，再通過修改參數、修改參考模板、兩級識別等各種提高語音識別精度的方法來提廣東工業大學工學碩士學位論文高識別率。 -
Ii to develop electronics commercial affairs is an important way of the existence and development of the medium - small sized enterprises according to the characteristics of medium - small sized enterprise the author sets forth the importance the current situation, change and opportunity even problems of developing electronics commercial affairs in those enterprises iii the development of applied electronics commercial affairs system in the medium - small sized enterprises in the development and application of electronics commercial affairs, there are always many disadvantages, such as short range, weak results and so on the author gives some ideas about developing electronic commercial affairs in the medium - small sized enterprises from business management and thinks that it should experience four steps - practicable analysis, applied system plan, applied system analysis and applied system design in the process of development design, many things should alse be paid at attention too iv the operation of electronics commercial affairs system in this part, the premise, preparation and process of electronics commercial affairs system are introduced v the management of electronics commercial affairs system, web sites propaganda and daily supervisory are the basic work, and accomplishing the work plays a large part in the system,

The table is a important device in the hardware - in - the - loop simulation system, and it simulates the flight of unmanned aerial vehicle so as to achieve flying parameters from those sensors. the signals of sensors in the table are transmitted by many cables previously, thus it confines the movement range of the three - axis frameworks. as the perfomance of uav become complicated, the signals cables are replaced by wire rings in some tables, but it brings many difficulties and unreliable factors for the simulation table ’ s design also. bluetooth, as a new short - range wireless communication technology, is a reasonable and feasible scheme in this condition
三軸模擬轉臺是無人機地面半實物模擬系統中的重要設備，用來模擬飛機在空中的姿態和角運動，以驅動傳感器產生飛行姿態、角速度及角加速度信號。早期轉臺上傳感器信號通過穿在框架中的電纜進行傳輸，這就限制了框架的運動范圍。隨著無人機任務的復雜程度不斷提高，出現了採用導電滑環傳遞信號的模擬轉臺，但這也給轉臺設計帶來了困難，且存在不可靠因素。
