  1. In hardware, we choose anti - disturbance photoelectric isolative sensor, take rc filter to resolve high - frequency for anti - disturbance. in software, we adopt arithmetic of recursion mean value to collective signal values to resolve low - frequency ac and pinnacle pulse disturbance

    在硬體方面，選用抗干擾能力強的光電隔離電量傳感器，並採取rc濾波抗干擾措施解決中高頻干擾問題；在軟體方面，對採集到的信號量採取遞推平均值演算法，解決低頻交流和尖峰脈沖干擾問題。
  2. Sonic noise can be solved through using arithmetic mean in place of the real numerical value to increase signal and noise ratio

    對于聲噪聲，我們採用算術平均值來代替其真值的方法來提高回波的信噪比，從而對聲噪聲進行抑制。
  3. In the course of design, we fully consider the actual conditions on the railway and take a series of corresponding measures to the concrete problem. such as we select high - accuracy microconvertor and have the converted function in succession data collecting system chip aduc812, design v / f circuit and external a / d circuit. in anti - interference of the hardware, we try to disperse each function module to avoid interfering each other, adopt photoelectric isolated technology to dispel the circuit connection of input and output. in controlling we import arithmetic mean into strain wave algorithm and real computing technology of virtual value for sample treatment of data, that is using the software to smooth away interfere error and to calculate actual value, thus it makes the precision of the data improve greatly

    在設計過程中，根據系統要求，充分考慮鐵路上的實際情況，針對具體問題採取了一系列的相應措施，如在器件選擇方面選用高精度microconvertor系列、具有adcdma連續轉換功能的數據採集微控制器晶元aduc812 ，設計了v f變換電路和外部a d轉換電路；在硬體抗干擾方面，將每個功能模塊盡量分散獨立開來以避免相互干擾、採用光電隔離技術消除輸入輸出通道上的電路聯系；在控制方面對于采樣數據的處理引入了算術平均值濾波演算法和真有效值的計算方法，即通過使用軟體來濾除系統中有干擾造成的誤差並計算真值，從而使數據的準確性得到極大地提高。
  4. The comprehensive ranking of a site or entity depends on the arithmetic mean value of the following parameters : visit rate, average number of days a cyber user visits the site or entity, non - repetitive pages opened and total number of pages opened, average time and number of times a cyber user visits the site or entity

    某網站或實體的整體排名是由以下指標的算術平均值決定的：到達率平均每個網民訪問該網站或實體的天數打開的不重復頁面和整體頁面展開數平均每個網民訪問該網站或實體的時間和訪問次數。
  5. In the image preprocessing that includes image smoothing and linear gray level transformation, the author brings forward a mended linear gray level transformation based on mean of gray value to enhance the image contrast. in the segmentation the paper presents an arithmetic taking the area of the pointers and construction feature of the water meter into consideration, which can extract the part of pointers in the special space of the water meter, and then binarizes image using a dynamic threshold based on the area of the pointer. the design can enhance the recognition rate for the next step

    在預處理中提出了一種基於灰度期望的分段線性變換；對水表的圖像分割，提出基於面積和結構信息的二值化自動分割，包括基於結構和灰度特徵的哈夫變換分割法（指針信息區的提取）和基於指針面積的特徵的閾值分割（指針提取） ；針對指針圖像的非均勻光照、背影等干擾，提出基於多特徵的分區模板匹配法對指針的方向進行識別，從而計算出讀數。
  6. This paper presents 4 parameters which contain the information of distribution of characters and background, realizing the unifying the background color. then the author brings forward a mended binarization method based on mean of gray value. in the segmentation the paper presents a arithmetic taking the projection, character width and the shape of the character in to consider

    本文利用4個包含字元背景分信息布的參數，實現了背景色的統一；在預處理中提出了一種基於灰度期望的改進二值化演算法；字元分割階段在豎直投影法的基礎上，提出利用自適應的字元寬度和字元的凹凸信息將牌照分割為單個字元；最後使用bp神經網路進行字元的識別。
