每年波音公司测试和评估飞行测试组织测试许多飞机。一个或两个航班大多数测试涉及50至100个参数。飞机认证可能需要多达250000个参数,并持续几个月。在过去的20年中,我们希望有一个模块化的系统,将允许我们使用最低限度的采集硬件来完成工作。同时,我们想培养一个系统的仪器工程师。我们有一个基于网络的数据采集系统,实现了这两个目标。我们通过在数据采集单元(DAU)使用IEEE 1588精密时间协议标记的所有数据解决了以太网的不确定性。DAU本身是一个小模块,允许我们安装只是我们需要一个给定的程序对于数据采集单元集。这使我们能够实现全方位的系统,但所有的人都用相同的硬件和软件操作。本文讨论了我们实施的体系结构和我们这个成功的系统。
Every year Boeing tests and evaluates flight test organizations to test many airplanes. Most tests on one or two flights involve 50 to 100 parameters. Aircraft certification may require up to 250,000 parameters for several months. For the past two decades, we wanted a modular system that would allow us to get the job done with minimal acquisition hardware. At the same time, we want to develop a systematic instrumentation engineer. We have a web-based data acquisition system that achieves both of these goals. We solved the Ethernet uncertainty with all the data tagged in the Data Acquisition Unit (DAU) using the IEEE 1588 Precision Time Protocol. DAU itself is a small module that allows us to install just what we need for a given set of programs for data acquisition units. This allowed us to implement a full range of systems, but all were operated on the same hardware and software. This article discusses the architecture we implemented and our successful system.
