海域水环境监测系统开发——青岛胶州湾实例研究

Development of a Marine Environment Monitoring System Based on GPRS:Case Study in Jiaozhou Bay of Qingdao

介绍了国外海洋环境监测技术的监测方式、监测平台、监测要素等内容发展研究现状,总结了当前我国监测技术面临的主要问题。在此基础上,以青岛胶州湾海域为研究对象搭建了海洋水环境监测系统,该系统可通过水下传感器对水体中的p H值、温度、盐度、溶解氧、叶绿素、氮、磷含量等指标进行监测,并通过GPRS模块将数据实时传输到位于陆上的数据监测中心,当数据显示超标时,本系统还可根据海上监测仪器所在位置确定污染区域和范围,指导监测车迅速开展陆地污染源分析,并做出快速应对决策以控制污染物。

This paper introduces the development and research status of overseas marine monitoring technologies in the aspects of monitoring methods, platforms and elements, and summarizes the major problems in China ’s marine monitoring sector. On the foundation of previous study, a marine environment monitoring system was established in the Jiaozhou Bay of Qingdao in Shandong Province. Using single-chip integration system and GSM/GPRS wireless communication technology, marine parameters are monitored remotely and dynamically at a longterm fixed-point, including p H, temperature, salinity, dissolved oxygen（DO）, chlorophyll, nitrogen and phospho-rus. Through the GPRS module, the collected data are transmitted to the on-land data monitoring center in a real-time way. When the monitored values exceed the standards, the system will locate the pollution area ac cording to the site of monitoring apparatus, so as to guide the monitoring vehicle to quickly carry out analysis on pollutants from land-based sources. It provides technical support for determining the scope and sources of marine pollution.
