【摘要】 文中研究了利用全球定位系统GPS授时技术来实现同步数据采集。设计了一种基于DSP的数据采集系统,由GPS秒脉冲同步下进行数据采集。采集的数据经处理为其打上时间和地理位置标签并采用USB 2.0接口来实现实时测量数据高速上传,为异地数据分析和处理提供了便利。更多还原

【Abstract】 This paper studies the use of Global Positioning System GPS timing technology torealize synchronize data acquisition.Designing a kind of a DSP-based data acquisition system,synchronized by the GPS pulse per second under the data acquisition.Collection of data treated for their marked time and location labels and with USB 2.0 interface to realize real-time measurement data high-speed uploading whichprovides a convenient off-site data analysis and processing.更多还原
