摘要
为优化深海激光原位拉曼光谱系统,对控制模式和数据通信方案进行了升级,以实现了光谱原位探测系统小型化。采用单一的STM32微控制器实现了光谱数据采集、光谱仪与激光器工作状态控制和系统工作环境参数监测等功能。取代了原型机由PC104和MSP430组成的双控制器系统,优化了控制机制。使用优化的激光拉曼光谱系统,实地测量了青岛近海海水和校内人工湖水的有色溶解有机物(CDOM)浓度,通过TCP/IP协议上传光谱数据。实验结果验证了拉曼系统小型化改进的可行性,本研究为海洋探测仪器的优化设计提供了新思路。
In order to optimize the deep-sea in-situ Raman spectroscopy system,the control mode and data communication scheme were upgraded,and the goal of miniaturization of the spectral in-situ detection system was realized.Through a single STM32 microcontroller,the system achieved the function of spectral data acquisition,spectrometer and laser working state control and system,we working environment parameter monitoring.The STM32 replaces the dual controller system consisting of PC104 and MSP430 and optimizes the control mechanism.Using the optimized laser Raman spectroscopy system measured the concentration of colored dissolved organic matter(CDOM)in Qingdao offshore water and intramural artificial lake water in the field,and uploaded the spectral data by TCP/IP protocol.The experimental results verify the feasibility of the miniaturization improvement of the Raman system.This study provides a new idea for the optimal design of marine detection instruments.
