三维测力台数据采集和处理自动化系统的研制

Development of an Automatic Data Collectingand Processing System of 3-D Plateform

本文研制一套三维测力台数据采集和处理的自动化系统，数据采集和处理全部由紫金Ⅱ（ＡＰＰＬＥⅡ）微机控制完成，每次采样共得到１５３６个点．Ｚ、Ｘ、Ｙ三个方向各５１２个点，将采得数据存入磁盘、通过对数据的处理可得到Ｚ、Ｘ、Ｙ三个方向力值与时间的对应值，Ｚ、Ｘ、Ｙ三个方的冲量值以及原地纵跳人体重心腾起的初速度和高度并打印、绘图输出结果。本研究改进了运动生物力学测试手段，比较准确、快速地获得多项力学指标，为运动技术的生物力学分析和教学提供依据。

In this paper,a set of automatic data collecting and processing system of 3-D plateform was in troduced. This system was computerized and controlled by common Apple 11.1536 points (512 points for each of x,y,z)were recorded with disc at each test and force values and impulses in three directions of X,Y,Z were obtained and displayed in screen instaneously after the performance was finished. In the software also the calculation procedure of the initial velocity and C. M. height in the air of the vetical jump ...
