摘  要：
水产养殖水质状况复杂,容易突发水质变化,水体光谱数据可直接反映这些变化。设计了一套养殖水体光谱观测系统,为开展养殖水体光谱分析并评估水质状况提供数据基础和科学依据。基于高精度光学传感器、Flash存储技术、GPRS及RS485无线数据传输技术构建一套实时、自动化的光谱观测系统,用以观测养殖池塘水体特定波段光谱数据。通过对5个池塘水体样本进行连续观测,以美国ASD公司的地物光谱仪在680 nm、700 nm和769 nm三个波段位置的同步观测数据为标准值进行回归分析,并对系统性能指标进行量化分析,得到观测数据准确度达98%以上,且系统性能达标。结果表明:在针对养殖水体特定波段光谱观测方面,该系统可以代替人工光谱仪观测工作,实现远程、实时数据观测,减少繁琐的观测程序,节省人力物力,同时能够避免人工观测造成的误差。

摘  要：
The water quality of the aquaculture is complex and easily mutated. The spectrum data of water can reflect the mutation directly. A spectrum observation system for aquaculture water is designed to provide data basis and scientific ground for spectrum analysis of aquaculture water and evaluation of water quality. A realtime and automatic spectrum observation system is constructed based on the high-precision optical sensor,Flash storage technology,GPRS and RS485 wireless data transmission technology to observe the spectrum data of specific bands in aquaculture pond. Through continuous observation of samples in 5 ponds,after regression analysis with simultaneous observation data of ASD spectrometer in the bands of 680 nm,700 nm and 769 nm as standard value,and quantitative analysis of system performance index,it is obtained that the accuracy of the observed data is above 98%,and the system performance is up to standard. The result shows that,for spectrum observation of aquaculture water in specific band,this system could take the place of artificial spectrometer for observation,realize remote and real-time data observation,reduce tedious observation procedure,economize on manpower and material resources,and avoid error caused by artificial observation.
