Research of NMR Oil Content Detection System Based on AVR

By using magnetic resonance imaging detection technology, the paper researches an implemented method about NMR oil content detection system based on AVR. According to the NMR principle, the generation of scanning signal and data processing are done at the same time with a single chip of ATmega32. Simultaneously, the arithmetic of dual-channel PR filter banks is also introduced to increase operational efficiency and to reconstruct the signal for LCD display. The system is designed for use in the oil content measurement of oilseed or some dynamic processes´ detection.
