One is to use fourier transformation to convert the source signal from time domain to frequency domain and to discard high frequency harmonious components upwards of 19 ( gb / t14953 - 93 d5. 3 demanding ), then to have static huffman coding to the quantized char array which is composed of reserved direct current component and basic wave and each high frequency " s amplitudes and angles. the other is to use discrete wavelet transformation to convert the source signal from time domain to frequency domain and to set the high frequency coefficients that its absolute value is smaller than the given threshold to zero, then to have dynamic huffman coding to the quantized char array which is composed of multiple, wavelet ' s level, datum length, low frequency coefficients and reserved high frequency coefficients. mass simulinks and analyses under the two circumstances have done to show that data compression ratio is small and the relative error is also small and within the permission of engineering and the compression problem can be solved in theory of measured datum of power system
第一種情況的壓縮方法為：採用傳統的傅立葉變換把原始信號從時間域變換到頻率域，舍棄20次及其以上的高次諧波成分（保證了gb / t14953 ? 93d5 . 3要求） ，然後對保留的直流分量、基波和各次諧波的幅值和相角數據量化后和量化時分別乘以的倍數系數構成一個數組，以字元形式保存，採用靜態huffman編碼對變換數據進行壓縮；採用離散小波變換把原始信號從時間域變換到頻率域，然後對分解得到的高頻系數進行閾值量化處理，對乘以的倍數系數、小波變換的階數、小波變換后的低頻、各級高頻以及原始數據長度、量化后的低頻系數以及保留的高頻系數大小、位置構成一個數組，以字元形式保存，採用動態huffman編碼對這個文件進行壓縮。 -
According to request that military put forward, the target car that subject research should have such characteristics as remote control, high precision, good safeguarding, needing no track, etc, so as to achieve purpose of course require correctly when training to carry on cannon static to static, static to move, move to static, move to move etc. target car transfer speed require low inertia, high accuracy, high dependability, stupid and getting excellent and kind systematically ; wireless communication system expect much dependability, better anti - interference ability ; computer control system demand and try one ' s best to adopt advanced technology, components and parts source of goods reliable, high dependability, structure to be simple, have serial communication, digital display, systematic trouble examine and function of showing etc. the job of this thesis is divided into three major parts : the proposition and confirming of the electric power pulls, specification requirement and selecting type of equipment of communication system, sureness of the computer control system scheme
