摘要
根据高精度电能质量监测装置的实际应用需要,对比分析了交流采样中软件同步采样与硬件同步采样对前端信号精度的影响。采用硬件同步采样技术,设计了电能质量监测装置数据采集模块。给出了基于AD I公司的AD7656的数据采集模块的设计电路,以满足实际应用中电能质量监测装置对前端信号精度的要求。该模块已应用于实际监测装置中,并获得了良好的效果。
According to the need of practical application of high-precision power quality monitoring devices,the impact of front-end signal,by AC sampling in software and hardware synchronous sampling of accuracy was analyzed and compared. A data acquisition module by using hardware synchronous sampling techniques was designed.A design of data acquisition module circuit to meet the practical application of power quality monitoring device on the front-end signal accuracy based on ADI s AD7656 was given.The module had been used in the actual monitoring devices and had a good performance.
