摘要
本文报道了配有信号调节放大器的三维测力系统的研制,该系统和一台Apple Ⅱ型计算机或一台长城0520型计算机(与IBMPC-XT兼容)相联接。文中先介绍测力系统,然后讨论测力平台和计算机之间的接口电路、数据采集的自动触发以及五道数据采集的编程。并提供了电路图和程序框图,最后,我们还提供了用Apple Ⅱ和长城0520计算机采集的跳远和步态分析的力对时间的变化曲线。
A three dimension force measuring system filled with signal conditioning
amplfier was developed. An Apple Ⅱ computer or a Great Well 0520 computer (consistent
with IBMPC-XT) was iinked to this system for A/D conversion, date acquisition and real
processing. In this paper we introduce the forct measuring system and discuss the interface
circuit between the force platform and the computer, the automatic triggering of the data
acquisition and the Frogram composition of the data acquisition of the five channels. The
circuit figures and the program charts are provided. The plots of force versus time of jump
and gait acquisited by an Apple Ⅱ and a Great Well 0520 computer are also provided.
