Nie Wen-ya · Journal of Anqing Teachers College · 2015
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,where the device data acquisition unit of new fault oscillograph are collected and deal with by using high performance DSP chip TMS320LF2812,the data management unit is completed by using S3C2410 chip to storage data,display and communication function. Test results show that the new fault oscillograph could separately install in each substation and has stable operation and high communication capacity advantages.
