摘要
基于Windows/PXI技术的传统数据采集系统不能保证采集的准确性和可靠性,有时出现"丢数据"的现象.针对这些问题,通过分析CPCI总线下数据采集卡的特性,设计实现了一种基于VxWorks/CPCI技术的雷达回波信号数据采集系统.该系统满足了数据采集的实时性、可靠性与准确性要求,并加入了网络FTP传输功能,实现了采集数据的实时传输,简化了一些繁琐的数据导出操作.同时使用VC++6.0编写分析软件,对采集到的雷达回波信号数据进行分析,取得了较满意的实验结果,进一步确认了该采集系统的可行性与可靠性.
The traditional data acquisition system based on Windows / PXI technology can not guarantee the accuracy and reliability of collection, and sometimes appears ＂lost data＂ phenomenon. In view of these problems, a radar echo signal data acquisition system was designed based on VxWorks / CPCI technology, by analyzing the features of data acquisition card under the CPCI bus. The system meets the real-time, reliability and accuracy requirements of data acquisition, and has the network FTP transfer function to achieve real-time transmission of data col- lection, simplifying the cumbersome operation of data export. At the same time, the collected data of radar echo signal was analysed using the analytical software written by VC ＋＋ 6.0. The results are satisfactory, which further confirms the feasibility and reliability of this acquisition system.
