| Abstract: | 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. |
