滑动轴承实验台的计算机通信与实验数据处理

The Computer Communication and Data Processing of Sliding Bearing Work Bench

基于滑动轴承实验台的工作要求、结构与工作原理 ,笔者设计了实验台动态测试中的数据通信系统 ,使采样的信号经A/D转换器后 ,能由 80 31单片机正确传输到上位机中。在后续的数据处理中 ,结合实验系统的特点 ,采用的是数据的稳定测试和曲线拟合等特殊的处理方法。这些方法很难由前端的单片机或测试电路实现。可见 ,利用数据通信和上位机的强大分析功能可以使系统资源得到最大可能的利用。

Based on the work demand,Structure and principle of s li ding bearing work bench,the author designed the data communication system for th e dynamic testing.The sampling anolog signals can be correctly transferred to PC by 8031 SCM via serial asynchronous communication of A/D transformer.For data p ost processing,the peculiar data processing methods such as the stability testin g and the curve fits were adopted in the light of special conditions of the expe riment system,which are difficult to be handled by the 8031 SCM or testing circu it.Thus it can be seen that the combination of data communication and powerful a nalytical function can develop the sysem resource furthest.
