数据采集系统(DAS:Data Acquisition System)是采集传感器输出的模拟信号并转换成计算机能识别的数字信号,然后送入计算机进行相应的计算和处理,得出所需的数据的系统。它将计算得到的数据进行显示或打印,以便实现对某些物理量的监控。由于新一代机载数据采集系统已被被广泛应用于战斗机、运输机、大型客机、支线客机、导弹和运载火箭,因此,下面对新一代机载数据采集系统作详细介绍。

Data Acquisition System (DAS: Data Acquisition System) is a system that collects the analog signals output by the sensors and transforms them into digital signals that the computer can recognize, and then sends them to the computer for corresponding calculation and processing to obtain the required data. It displays or prints the calculated data to monitor some of the physical quantities. As a new generation of airborne data acquisition system has been widely used in fighter jets, transport aircraft, large passenger aircraft, regional aircraft, missiles and launch vehicles, the following a detailed description of the next generation of airborne data acquisition system.
