一种风洞现场总线技术的研究与实现

Research and implementation of field bus in wind tunnel

主要目的是对现场总线技术的核心技术计算机技术进行研究,使得不同于传统测控技术的现场总线技术可以应用于风洞试验中。首先设计出了一套基于以太网的风洞现场总线方案;研究了嵌入式Linux实时操作系统、PCI板卡及其驱动程序、异种操作系统网络互连的基本原理和实现技术。通过对以上几种计算机技术的研究,实现了现场总线技术在风洞中的应用。

The main purpose of this paper is to research computer technology --the core technology of field bus, so that field bus technologies that are different from conventional ones can be used in wind tunnel tests. In this paper, a field bus scheme based on ethernet for wind tunnel is designed after comparison. The basic principles of the real time OS of embedded Linux, PCI card and its drivers, the network interconnecting software of heterogeneous OS are studied. After study of several technologies mentioned above, the application of field bus to the wind tunnel are realized.
