Data mining (DM) is the extraction of hidden predictive information from large databases (DBS). With the automatic discovery of knowledge implicit within DBS, DM uses sophisticated statistical analysis and modeling techniques to uncover patterns and relationships hidden in organizational DBS. Over the last 40 years, the tools and techniques to process structured information have continued to evolve from DBS to data warehousing (DW) to DM. DW applications have become business-critical. DM can extract even more value out of these huge repositories of information.

针对科研实验中对拉压千斤顶加载过程控制的需要，采用ATmega128单片机控制步进电机进而实现对执行系统的电动泵站实行自动控制。对力和位移的数据采集与处理及用步进电机控制电动泵站手柄的技术细节作了重点描述。通过单片机的A/D变换器对AMP放大模块采集的电桥信号作量化处理，千斤顶的操控手柄位置依电动油泵阀门开启的方向和大小作若干定位，单片机根据力或位移传感器信号，实时控制步进电机驱动手柄旋转到相应操控位置。 Abstract: This article describes the use of ATmega128 AVR microcontroller series of DBS electric pumping stations and QF100/200 separate twoway hydraulic jack to automate the process of manipulating the work of the technical content. Articles on force and displacement data acquisition and processing， and stepper motor control electric pump with the handle of the key technical details were described. Through the MCU’s A / D converter module is collected on the AMP amplification quantify the signal bridge， jack handle position control valve opening according to the direction of electric pumps for a number of positioning and size of the microcontroller based on force or displacement sensor signals， real-time control stepper motor drive control handle rotate to the appropriate location.
