Testing signal transformation processing 測試與信號變換處理
The signal transformation circuit is impoldered make use of protel software 利用protel軟件開發(fā)了信號轉(zhuǎn)換電路。
Components of the system are realized . the system is made up of signal transformation part , image processing part , acquirement and transport of the position of defect part . 2 設(shè)計并實現(xiàn)了x射線無損探傷系統(tǒng)的硬件組成與結(jié)構(gòu),該探傷系統(tǒng)主要由信號轉(zhuǎn)換、圖像處理以及缺陷位置信息獲取與傳輸三部分組成; 2
The main research in this thesis can be summarized as follows : ( 1 ) the structure and features of tc620 turbo cycling compressor are introduced . its frequent faults , fault mechanism and diagnosis are also analyzed . ( 2 ) the vibration signal analysis based on fault analysis and processing are presented , including wave analysis , tarce analysis , frequency spectrum analysis etc . and connected signal transformation ideas are also described , which can be conducted in amplitude field , time field and frequency field according to different needs 本文主要包括以下內(nèi)容: ( 1 )介紹了tc620透平循環(huán)壓縮機的結(jié)構(gòu)特點,歸納總結(jié)了其常見的故障現(xiàn)象,分析了各類故障產(chǎn)生的機理和診斷方法; ( 2 )論述了基于故障分析處理的幾種常用的振動信號分析法,如波形分析、軌跡分析、頻譜分析等。
Usually point a kind of inside to pack the arithmetic figure cent the network with the box of the power enlarger . arithmetic figure type the power enlarger for method for signal for inputting for arithmetic figure comparing , at with arithmetic figure signal handling again and again partitioning the empress , then and respectively these signals transformation is imitating the signal , then again from eachly from of box enlarge the empress to go to again to push the the cowgirl in the box to pronounce the unit 通常指一種內(nèi)裝數(shù)字分頻網(wǎng)絡(luò)和功率放大器的音箱。數(shù)字式音箱輸入的信號為數(shù)字比特流,在用數(shù)字信號處理的方法將音頻頻譜分割后,便分別將這些信號變換為模擬信號,然后再由各自的功率放大器放大后再去推動音箱中的相應(yīng)發(fā)音單元。
Using the idea of multiscale analysis and by combining the model - based analysis method for dynamic systems with the multiscale signal transformation method , we put forward a new algorithm of multiscale distributed information fusion estimation . for multi - model dynamic systems having different description for target state at different scales , at the finest scale we can obtain the optimal fusion estimates based on global information , which give a primary solution to the information fusion estimation of multiscale dynamic systems . this work enriches and develops the information fusion theory 利用多尺度分析的思想,將基于模型的動態(tài)系統(tǒng)分析方法與基于統(tǒng)計特性的多尺度信號變換方法相結(jié)合,在不同尺度上擁有對目標(biāo)狀態(tài)進行不同描述的多模型動態(tài)系統(tǒng),提出多尺度分布式信息融合估計新算法,在最細尺度上獲得目標(biāo)狀態(tài)基于全局信息的融合估計值,初步解決了多尺度動態(tài)模型信息融合問題,這些工作豐富和發(fā)展了信息融合理論
