多路并行数据采集系统可以较好地实现Ａ／Ｄ采集的同步性和实时性，对于观察某瞬态时刻各路采集信号的状态很有意义。本文介绍了该系统的两种实现方法，合理地解决了限制采集路数和采样速率的问题，具有高速、高精度、多路同步采集及实时处理等特点，可广泛用于风洞吹风、发动机实验等诸多数据测试系统中。 Multiple parallel data acquisition system can achieve the A / D acquisition of synchronization and real-time, for the observation of a transient moment of the state of the signal acquisition is very meaningful. This paper introduces two methods to realize this system, reasonably resolves the problem of limited number of acquisition channels and sampling rate, and has the characteristics of high speed, high precision, multiple simultaneous acquisition and real-time processing, and can be widely used in wind tunnel blowing, Experiments and many other data test system.
