基于物联网技术的水质监测系统中不同溶解氧传感器应用效果初探

摘要

将测量原理不同的电化学和光学溶解氧传感器分别集成在基于物联网的水质在线监测系统中，并应用于长时间监测海水养殖场的溶解氧，结果表明：两种传感器都能在一定时间内正常监测水体中的溶解氧，但基于传统原电池法的电化学溶解氧传感器在海水养殖水质监测中稳定性较差，维护复杂；而基于动态荧光淬灭的光学溶解氧传感器监测值相对比较稳定，且维护简单。本研究在实际应用层面上为两种类型溶解氧传感器的使用提供了技术参考。%Two kinds of dissolved oxygen sensors with different measuring principles (electrochemical method and optical fluorescence method)were integrated in the online water quality monitoring system based on the Internet of Things,and were used for long -term monitoring of dissolved oxygen in seawater farms.The results showed that both the two kinds of sensors could normally monitor the dissoved oxygen in a certain peri-od.The dissolved oxygen sensors based on optical fluorescence method exhibited excellent long -term stability and simple maintenance relative to galvanic cell sensors in marine culture.This study provided technic refer-ences for the practical application of the two kinds of dissolved oxygen sensors.
