基于无线传输的水质监测生物传感器设计研究

Design of a water quality monitoring biosensor based on wireless transmission

为弥补传统水质监测耗时长、不能及时反映水质污染状况且智能度低的问题,设计了基于无线传输的水质监测生物传感器。以监测水质生化需氧量(BOD)为监测主体,集成温度(T)、酸碱度(p H)及溶解氧(DO)共计四项水质监测项目。论述了BOD生物传感器的工作原理,设计了多参数集成型水质监测生物传感器的整体结构,阐述了测定多参数水质指标及后端无线传输等过程,为水质监测生物传感器向高度智能化方向发展及仪器的下一步开发提供了基础。

Traditional approaches for water quality monitoring are always time-consuming and unintelligent and thus fail to reflect the water pollution situation in real-time. To address this issue, a novel biosensor for water quality monitoring based on wireless transmission is designed in this paper. Biochemical Oxygen Demand （BOD） is main target of water quality monitoring, as well as temperature （T）, acidity （pH） and dissolved oxygen （DO）. Working principle of BOD biosensor is introduced integrated Overall structure of the multiparameter- biosensor for water quality monitoring is presented. The processes of the water quality indicator measurement and wireless data transmission at back-end are described. It is fully convinced that this work not only provides an approach to design such biosensors applied in the applications, and also significantly contributes to the development of high-intelligence biosensors for water quality monitoring in the future.
