Mini-type internet-of-things laser induced breakdown spectroscopy medical sensor system

The utility model discloses a mini-type internet-of-things laser induced breakdown spectroscopy medical sensor system, all electronic circuits of power supply, control, refrigeration, mems (Micro-electromechanical Systems) grating spectrometer, cache, internet-of-things identity recognition and internet-of-things data transmission in an opto-electro-mechanical structure of the system are integrated into a microcircuit system, all the optical components are integrated into a mini-type pulse optical fiber laser system, by adopting the structure, the miniaturization degree of the system is improved and the miniaturization requirement of an internet-of-things sensor is met. When the system is applied in medicine, an MCU (micro controller unit) controls a ZigBee transceiver module to send an libs (Laser-induced Breakdown Spectroscopy) signal of biological tissues such as hair and the like of a system wearer to an internet-of-things server expert system to perform analysis, diagnosis and storage, wherein the libs signal is excited by a mini-type pulse optical fiber laser system, and the diagnosis result of the expert system can be received by the ZigBee transceiver module.
