介绍一种基于PCI-1711高速液压油缸内壁参数测量的数据采集处理系统，将采集到的数据传送至上位机后．利用VB6．0数据处理软件，将采集的数据转换成坐标值，根据最小二乘拟合，拟合出被测油缸截面的圆心坐标和半径。再根据相关算法，计算出油缸内壁的直径、直线度、圆柱度等参数，以用于出厂产品的检测。
介紹一種基于PCI-1711高速液壓油缸內壁參數測量的數據採集處理繫統，將採集到的數據傳送至上位機後．利用VB6．0數據處理軟件，將採集的數據轉換成坐標值，根據最小二乘擬閤，擬閤齣被測油缸截麵的圓心坐標和半徑。再根據相關算法，計算齣油缸內壁的直徑、直線度、圓柱度等參數，以用于齣廠產品的檢測。

This paper introduces a data acquisition and processing system which could test parameters of intrinsic surface of hydraulic ram and based on PCI-1711 high speed data acquisition card. After being transmitted to principal computer, the acquired data are changed into coordinates by VB6. 0 data processing software to fit the circle center and radius of the measured cross-section of the cylinder by least square method, and to calculate the diameter the straightness and the cylindricity of intrinsic surface of hydraulic ram according to relevant algorithms. The measured parameters could be used to test outgoing products.
