針對科研實驗中對拉壓千斤頂加載過程控制的需要,采用ATmega128單片機控制步進電機進而實現對執行系統的電動泵站實行自動控制。對力和位移的數據采集與處理及用步進電機控制電動泵站手柄的技術細節作了重點描述。通過單片機的A/D變換器對AMP放大模塊采集的電橋信號作量化處理,千斤頂的操控手柄位置依電動油泵閥門開啟的方向和大小作若干定位,單片機根據力或位移傳感器信號,實時控制步進電機驅動手柄旋轉到相應操控位置。
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.
介紹了一種基于MSP430系列單片機和ADXL203加速度傳感器的數字式傾角儀,它不僅可以實現水平度檢測,而且可以測量00~3600范圍內的任意傾角,分辨率可達O.1。。此外,由于該傾角儀輸出為數字結果,因此它也可以與其他的數字設備結合起來,組合成一個功能更加強大的儀器。該數字傾角儀可廣泛應用于建筑、機械、道路、橋梁、石油、煤礦和地質勘探等各種需要測量重力參考系下傾角的場合。關鍵詞:MSP430F133單片機;力敏傳感器;ADXL203加速度計;角度測量
Abstract:This paper presents a new style digital inclinometer which is developed on the basis of the MSP430F133 MCU and the ADXL203 dual axis aeeelerometer.This inclinometer not only can test levelness,but also can measure any angle between 0。and 360。with an accuracy of 0.1 O.In addition,its output is a digital result,which makes it possible to integrate itself with other digital devices to form a more functional unit.This inclinometer can be widely used in any construction site,oil field,coal-mine or geologic survey and SO on where it will provide the working people with convenience to measure any angles.Key words:MSP430F133 MCU;force sensor;ADXL203 accelerometer;angle measurement
