摘要
介绍一个多通道多采样率的数据采集系统。该系统输入64个模拟量均要转换成数字信号,数据采集卡为基于VX I总线的E 1413,多通道之间的变采样率通过特殊的采样列表实现。文中给出了硬件组成、软件设计和测试结果。该系统已用于对飞机燃油试验台的测控。
This paper introduces data acquisition system for a multi-channel ＆ diverse sampling rates based on VXI bus, which changes the analog signals of 64 channels into digital signals with the Data Acquisition Card E1413. The channels sample at diverse rates via the special scan list in this system. Its hardware composition, software design and the test result are provided in this paper. The system is working well on the fuel test-bed of airplanes.
