Power Fault Recorder Based on Embedded Systems
Huang Wen-fang · Yibiao jishu yu chuanganqi · 2008
A design of power fault recorder based on the embedded systems was introduced.The system adopted modularization design,included data acquisition unit,and used human-machine interface unit and double CPU work with each other.The accuracy of data collection was apparently improved,because the data acquisition unit adopted hardware synchronous sampling.The DSP chip TM320 F2812 and A/D chip ADS8364 guaranteed high speed,efficiency,and reliability of the fault recorder.The human-machine interface included the chip S3C44B0X,the ethernet interface,the LCD interface,the USB interface,etc.And taking the ethernet interface as an example,introduced the detailed design.This solution is useful to the design of the equipment of detection equipment of AC parameters.
