Time Scale Sampling System Based on LPC1768 And AD7656

以微控制器LPC1768为核心控制AD7656的采样电路,实现了电力系统监测数据带上准确时间标记的设计方案。系统采用LPC1768片内资源SSP0控制AD7656进行采样,并使用片内资源RTC,以获得带有实时时间标示的采样数据。带时标采样系统在工业实时监测系统中有良好的应用前景。

This paper designs the AD7656 sampling circuit with LPC1768 microcontroller as the core to control the system,realizing the function of monitoring power system data with accurate timestamps.The system uses on-chip resource SSP0 of LPC1768 to control the AD7656 sampling,and uses the on-chip resource RTC to acquire sample data with real-time timestamps.Sampling system with a time scale has a broad application prospect in the industrial real-time monitoring system.
