PC采集系统分析

Analysis of PC acquisition system

讨论了基于PC声卡的仪器研制,阐述了声卡A/D转换性能优越、技术成熟,可以构建性价比相当高的数据采集系统,该方法使实验室在不投入太多的实验室空间和经费下,就能创建波形采集与显示等实验环节,并指出该系统通用性强、扩展性好、界面简单,在工程测量与实验室应用中具有广阔的前景。

The author discusses the instrument research based on the PC sound card, describes that the A/D conversion performance of the sound card is superior and the technology is mature, and the data acquisition system of the high performance-cost ratio can be built by using this, the method can make the laboratory not invest too much funds and space to create the experiment link of the acquisition and display of the waveform, and points out that the generality of the system is good, the expansibility of the system is good, the interface is simple, which has the wide application prospect in the engineering survey and the laboratory.
