一种基于PC104+总线的同步数据采集系统

A synchronous data acquisition system based on PC104 + bus

本文所阐述的数据采集系统,根据某直升机模型着水试验的数据采集需求而研制,试验过程中产生了大量的各种信号类型的数据。该采集系统采用了基于PC104+总线的多采集卡进行采集通道的扩展,以实现多通道多信号类型的数据采集,每套采集卡配置独立的PC104+主板和硬盘存储系统,采用外部控制的方式实现数据采集的同步。采集系统软件设计采用VC++程序语言。

The described data acquisition system is developed according to the data acquisition requirement of a helicopter model water seepage test. During the test,a large number of various types of data are produced. The acquisition system uses the multi acquisition card based on PC104 ＋ bus to expand the acquisition channel,and realize data acquisition with multi-channel and multi signal types. Each data acquisition card is equipped with an independent PC104 ＋ motherboard and hard disk storage system. The external control is adopted to realize the synchronization of data acquisition. Acquisition system software design use VC ＋ ＋ programming language.
