  1. The second part is a detector which is used to detect the distribution of voltage on the patient ' s brain surface from all different directions. the third is a mixed signal processor ( c8051f020 ) which is used to control the other parts of the system and display some necessary information and convert the voltage signals into digital signals, as well as transmit the acquired data to the computer. the fourth is computer with eit software which is used to analyze and process the received data and construct a picture for the brain edema and haematoma on screen

    32通道電阻抗成像系統由4個部分組成:第一部分是正弦波恆流源,用來產生注入大腦的激勵電流;第二部分是電位信號的提取與轉換,用來提取當激勵電流注入時,在大腦表面形成的電位分佈信號;第三部分是數據採集與控制系統,用來控制激勵電流的率,注入方向,注入強,控制採集大腦表面的電位分佈信號,並且將這些採集的電位分佈數據傳到pc機;第四部分是計算機eit成像軟體,用來接收下位機的電位分佈數據,並且對這些數據進行分析計算,重建電阻抗像。
  2. Abstract : in order to process signal in depth and to extract the fault feature from original signal in machinery diagnosis , the graphical display algorithm that can keep the data length of wavelet transform results the same as that of original signal is used. the fault diagnosis of a bend axial piston pump via b - spline wavelet that has linear phase is provided. the results of study demonstrate that the new method has excellent feature and the weak fault signal can be extracted from the strong vibration background of the pump

    文摘:採用具有線性相位的b樣條小波,應用形顯示演算法並結合小波變換快速演算法將信號分解到不同的帶上,且分解結果和原信號長保持一致,可對信號進行深次的處理,克服了傳統的信號處理方法不易提取微弱信息的不足.通過對礦用斜軸式柱塞泵振動信號的分析,分離出了配流副磨損、球鉸松動、缸體及泵軸支撐軸承的故障特徵,為液壓泵的故障診提供了依據,並為信噪分離、微弱信號提取及設備的早期故障診提供了一條有效途徑
