Design of a Double CPU and Distributed Coal Mine Fault Oscillograph

Abstract:

Traditional microcomputer fault oscillograph cannot meet the requirements of coal mine substation to digital and networked. A double CPU and distributed coal mine fault oscillograph is presented, the device data acquisition unit of new fault oscillograph use high performance DSP chip TMS320LF2812 to complete signal acquisition and processing, and S3C2410 chip is used in data management unit to complete the data storage, display and communication function. Test results show that the new fault oscillograph could separately installed in each substation and has stable operation and high communication capacity advantages.
