| 摘 要： | 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。

Two Methods to Realize High-Accuracy Multi-Channel Parallel Data Acquisition System |
| |
| Abstract: | Multi channel parallel data acquisition system can offer synchronous and real time property of data acquisition. It is important in observing the state of acquired signals at one transient moment. In this paper, two methods are proposed to realize this system, which reasonably solve the problems of limited amount of channels and acquisition speed. The system has such features of high speed, high accuracy, multi channel synchronous acquisition and real time processing, and can be widely used for many data testing systems as engine testing, wind tunnel testing and so on. |
