【摘要】 为了能够简捷、快速、精确地测量任意地理位置的重力加速度,设计并制作了一种以ATgema16为核心的单片机重力加速度测量装置。测量装置主要是测量其摆动周期,利用单片机的计时/计数器、中断功能来实现计数测量和时间测量,调用重力加速度与所记次数n、中断计时的关系式得出结果。并在显示屏上显示,实现了智能测量当地重力加速度的目的。更多还原

【Abstract】 In order to get a simple,fast and accurate measurement of gravitational acceleration in any geographical location,designing and producing a microcontroller device for measuring gravitational acceleration with the core of ATgema16 is presented.This measuring device is mainly used to measure swing cycle,make counting measurements and time measurements come ture with the use of microcontroller,s timer/counter and interrupt function,and get the outcome with the relationship between the gravitational acceleration and the noted number n,the interrupt timing,and be displayed on the screen,realizing computing local gravitational acceleration intelligently.更多还原
