基于嵌入式技术的双光谱水质多参数一体化系统设计

为了解决传统水质检测仪器存在的检测效率低、检测参数少、二次污染、集成度低的问题，提出了一种基于嵌入式技术的双光谱水质多参数监测系统设计方法。采用紫外吸收光谱和荧光光谱相融合的方法对其水质进行检测。为了验证设计系统的可行性，用其检测总磷(TP)、总氮(TN)、氨氮(NH₃-N)、高锰酸盐指数(COD_Mn)、水中油等参数，并与国标法进行对比，实验结果表明：该监测系统的性能和精度均符合设计标准。双光谱融合的水质多参数监测系统为多参数水质检测提供了技术支持，具有应用价值，为在线监测仪研究提出了一种新的设计思路。

Design of Dual-spectral Water Quality Multi-parameter Integrated System Based on Embedded Technology

In order to solve the problems of low detection efficiency,few detection parameters,secondary pollution and low integration of traditional water quality testing instruments,based on embedded technology,a design method of dual-spectrum fusion water quality multi-parameter monitoring system was proposed.The water quality was detected by the fusion of ultraviolet absorption spectrum and fluorescence spectrum.In order to verify the feasibility of the design system,total phosphorus(TP),total nitrogen(TN),ammonia nitrogen(NH 3-N),permanganate index(COD Mn)and water oil were detected.This method was compared with the national standard method.The experimental results show that the performance and accuracy of the monitoring system meet the design standards.The multi-parameter monitoring system of water quality based on dual-spectrum fusion provides technical support for multi-parameter water quality detection.It has application value,providing a new design idea for the online monitor research.
