基于PCI-2501的高速数据采集与反馈系统

由于实验室条件限制,发射装置在随主机进行综合航电系统试验时没有液压系统。为了满足实验室联试试验时的需要,使用凌华公司的数据采集卡DAQ-2501多功能卡搭建出系统的硬件平台,软件方面在VC++环境下,利用多线程技术设计实现了基于PCI的多通道高速数据采集与反馈系统,用于模拟发射装置的机构动作。详细介绍整个系统的设计思路,对其中使用到的关键技术进行了研究,实验证明,系统具有较高的可靠性。

Data Acquis Ition and Feedback System Based on PCI 2501

Because of the limit of the laboratory conditions,there isn’t hydraulic pressure system when the launcher do integrated avionics system test with plane.So we build the hardware platform using ADLINK Technology Incorporation ’s DAQ 2501 board and the software platform using VC＋＋ language,then realized the data acquisition and feedback system based on PCI to simulate the launcher’s action using the technology of mul-tithread.This paper Introduces the whole system’s design ideas in detail and researches on the key technology of the system,the test indicates that the system has high reliability.
