摘要
文章设计了一种基于STC15W4K56S4单片机控制的管道内钢珠运动测量装置。该装置采用霍尔传感器测量钢珠运动参数,通过钢珠在管道内的运动特点建立数学模型,利用数学模型实现对钢珠个数、运动方向、角度、周期的测量,通过标定法减小系统误差,并在12864LCD上进行显示。该装置可以较好地完成钢珠数量与运动方向显示,并且将倾斜角度误差的绝对值在误差范围之内。
In this paper,a steel ball motion measuring device in pipeline is designed based on STC15W4K56S4 single chip microcomputer.The device uses Hall sensor to measure the movement parameters of steel balls,establishes the mathematical model through the movement characteristics of steel balls in the pipeline,realizes the measurement of the number of steel balls,movement direction,angle and period by using the mathematical model,reduces the system error by the calibration method,and displays on 12864LCD.The device can display the number of steel balls and the direction of movement well,and the absolute value of the tilt angle error is within the error range.
