Aiming at the practical situations of frequent accidents on mine gas and existing mine gas wire communication system needs to be improved towards wireless communication system, the paper put forward all nodes of gas sensor distributed in underground were brought into an intelligent and flexible wireless network system, so as to form a gas sensor networks system with layering and characteristic of intrinsical safety which relayed on the sensor ' s node
摘要針對礦井瓦斯事故頻發、現有礦井瓦斯監測有線通信系統急需向無線通信系統改進的實際情況，文章提出了將分佈於井下的所有瓦斯傳感器節點納入一個智能化、結構靈活的無線網路系統，組成以傳感器節點為依託的層次化且具有本安特性的瓦斯傳感器網路系統。 -
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。 -
With the development of the power industry, the power system, the computer technique and the communication technique, the synthetic automatization of transformer substation has become a pop topic and caused the attentions of all sections in the power industry, and it has also become one of emphases that the power industry pushes the technique progress, it is because that : with the realization of the synthetic automatization of transformer substation, the safety of power network and the run level of economy can be improved, and the investment of foundation construction can be reduced ; with the increase of the complexity of power network, in order to hold the run state of the power network and the transformer substation in time, all levels of control center should take more information ; to improve the controllability of the transformer substation, it is required to adopt more remote concentrated control 、 concentrated operation, and anti - accident measures
隨著我國電力工業和電力系統、計算機技術和通訊技術的發展，變電站綜合自動化成為熱門話題，引起了電力工業各部門的注意和重視，並成為當前我國電力工業推行技術進步的重點之一。之所以如此，是因為:實現變電站的綜合自動化，可以提高電網的安全、經濟運行水平，減少基建投資，電網復雜程度的增加，各級調度中心要求更多的信息，以便於及時掌握電網及變電站的運行情況為了提高變電站的可控性，要求採用更多的遠方集中控制、集中操作和反事故措施。
