Abstract

The paper deals with a procedure for estimating the communication times in VXI measurement stations, mainly used in industrial environment with the aim of optimizing their global performances. At first, the proposed procedure analyzes the communication process in order to share the global communication time into elementary time intervals. Then, it evaluates each of them by a two channel oscilloscope used to probe the handshaking lines of the communication protocols. The basic intervals are then used to find general expressions of the communication time for any amount of data transfers with the same measurement station. On this basis, the factors responsible for the throughput loss deriving from communication bottlenecks can be put in evidence. Thus, the proposed procedure provides an useful investigation tool for increasing the station performance. In order to best put in evidence the benefits of the proposed procedure, its experimental application to a general purpose VXI measurement station is discussed as well.<>

基于vxi的测量站性能优化

本文研究了一种用于工业环境的VXI测量站的通信时间估计方法，目的是优化VXI测量站的全局性能。该方法首先对通信过程进行分析，以便将全局通信时间共享到多个基本时间区间。然后，用双通道示波器探测通信协议的握手线，对每个信号进行评估。然后使用基本间隔来求同一测量站任意数量的数据传输的通信时间的一般表达式。在此基础上，可以证明由通信瓶颈引起的吞吐量损失的因素。因此，所提出的程序为提高台站性能提供了一个有用的调查工具。为了更好地证明所提出的方法的优点，还讨论了其在通用VXI测量站的实验应用。
