本文給出了一種應用在寬頻帶地震記錄儀中基於gps授時信號的時間同步技術。Gps is a planet wireless conductance system which is global and all - weather, gps can offer high precision time orientation information to infinite user, clock precision reachs 10 ? 6 magnitude 。 not only changes traditional time method of quartz crystal clock, but also replaces wireless shortwave and even more lowfrequency signal and tv signal whose overlay range is limited and low precision, offers advantage to geology field task, achieve automatization and high precision of seismic flow observation
利用gps授時信號全方位、全天候、連續性、實時性和高精度的特點，以gps信號為基準來校準本地時鐘（晶體振蕩時鐘或原子鐘） ，將gps接收機輸出信號的長期穩定度和恆溫晶振的短期穩定度相結合，應用大規模可編程邏輯器件，設計和實現了由pc104控制的實時在線授時系統。The primary aim of the single chip microcomputer circuit of this project is data collecting, it applied the invention monopoly of professor zhang guanghui and professor peng donglin of chongqing university, make use of the high frequency inserted pulse, and join together the software to constitute subsidiary calibration distributed on equal time, complete the task of on - line subdivision in the dynamic measure process, finally up pass the data to pc, pc handle it and get examination result
下位機是硬體集成電路，利用重慶大學張光輝教授、彭東林教授的發明專利「計算機對脈沖信號的細分與辨向新方法」 ，附加頻率極高的外部插入脈沖，結合軟體構成按時間均勻分度的輔助標尺，實現動態測量過程中采樣點的實時細分，最終完成數據採集任務；上位機主要是軟體部分，利用pc機接收下位機的採集數據並進行分析處理，得出檢測結果。In this paper, chroma dc coefficients are selected as the carrier data because chroma dc coefficients are robust. also, alterable steps are used to select one part of the coefficients, so the watermark is imperceptible ; before watermark embedding, the watermark is divided into many parts, every part is individually embedded into one gop of the video, even if a gop is destroyed, the watermark can be extracted correctly, this methods promotes the robustness of the watermark ; in addition, in order to promote the security of the watermark, the user ' s id and password are used to generate chaos sequence by the chaos system which is created in this paper, later, watermark is mixed by the chaos sequence. also, the embedding position of the watermark bit is modified by one chaos sequence, so, unauthorized person can not extract or remove the watermark, since the embedding position is unknown
本文認為，色度dc系數是魯棒性非常好的參數，因而選擇色度dc系數作為水印信息載體，同時，採用可變的步長選擇部分系數，保證了水印的隱形性；在嵌入水印時，本文採用水印信息「網格劃分」 、各子塊獨立嵌入視頻的方案，由於水印信息子塊是相對獨立的嵌入視頻中的每一相對獨立的圖組當中，即使某一圖組收到一定破壞，也能夠恢復水印信息，使水印的健壯性得到提高；此外，為了提高水印信息的安全性，在嵌入水印信息時，根據用戶輸入的id號和密碼，利用本文構造的混沌系統產生的混沌序列對水印信息進行變換，同時，對每一水印信息比特的嵌入位置也採用了偽隨機序列進行調整，這樣，未授權用戶不能提取水印信息，也難以擦除其中的水印信息，因為嵌入的位置是未知的。Cleverlearn does not condone fraud : in the event of any unauthorized use of your account or unauthorized credit card charges or debit card charges, you must notify cleverlearn, and you will be responsible for such unauthorized use or charges until you notify cleverlearn

本論文的工作針對低頻時碼授時高端用戶的定時需求，對數字信號處理（ dsp ）這一新型技術在該領域應用進行了探索性研究，主要完成和開展了如下工作： （ 1 ）研究分析了低頻通道和dsp技術，根據系統要求，從硬體上實現了基於dsp晶元的低頻時碼信號的採集測試平臺。Based on the basic principle of wavelet analysis, multi - resolution analysis of signal in atomic clock is made. the coefficients of wavelet transform for synthesis atomic time, which are weighed and averaged at different wavelet scales, are obtained. then according to reconstruction theorem, multi - resolution synthesis time scale can be reconstructed. since the signal of atomic clock has been analysed by multi - resolution, we can use wavelet variance at different scales to weight and average the coefficients. thus either the difference in stability of different clock or the varying characteristic of the same clock at the different scale are all considered. finaly, this method is checked by the measured data from national timing serve center of shaanxi astronomy observatory. it confirmed that this technique, which is simple and practicable, is a new method of multi - resolution. from this method, the common characteristic of different clocks can be extracted. the stability of multi - resolution synthesis atomic time scale is obviously superior to that of other methods
本文根據小波分析的基本原理，對原子鐘信號進行多解析度分解，將分解后的小波變換系數進行加權平均，得到不同小波尺度綜合原子時的加權平均小波變換系數，然後由小波變換的重構條件，反演綜合時間尺度.由於對原子鐘信號進行了小波分解，利用不同尺度的小波變換系數的小波方差進行加權平均，這樣既考慮不同原子鐘在穩定性方面的差異，又顧及同一臺原子鐘在不同小波尺度的變化特性.最後根據陜西天文臺國家授時中心的實測數據對這種方法進行了檢驗.表明這是一種全新的多解析度綜合方法，這種方法比較簡單而切實可行，它能提取各個原子鐘的共同特性，多解析度綜合時間尺度的平穩性明顯優于其他方法I hereby authorize global link international ( gli ) billing center to charge the specified amount only if the assigned system account reaches the specified level of remaining credit each time to my credit card below for the international prepaid card auto top - up automatic payment service
