Description
TECHNICAL FIELD

[0002] Due to the advantages of non-destructive and non-radiation to the sample under test, nuclear magnetic resonance detection technology has been widely used in medical imaging and material detection and identification. A nuclear magnetic resonance spectrometer for material detection and identification usually consists of a magnet, a coil and a circuit system. The circuit system mainly includes a radio frequency pulse transmitting module, a transceiver conversion module, an FID signal receiving module and a signal processing module. The radio frequency pulse transmitting module of the conventional nuclear magnetic resonance spectrometer usually stores pulse sequence information in SRAM, and a microprocessor or a microcomputer reads out the pulse sequence information in SRAM, which is then sent to a programmable device to generate high and low levels corresponding to the pulse sequence, and then a pulse generator generates a pulse sequence. Most of the circuits in the transceiver conversion module and the signal receiving and processing module have been digitized. The time-domain free-decay signal FID enters the receiving circuit through a transceiver state conversion switch, and is processed after low-noise amplification, frequency conversion, intermediate frequency amplification and A / D conversion.
[0003] At present, the existing nuclear magnetic resonance spectrometer circuit based on singlechip generates a large amount of heat in the singlechip during operation, and if the heat is retained in the singlechip for a long time and cannot be discharged, it will affect the normal operation and service life of the singlechip.
