It is of great significance to have a rapid real-time monitoring of the change of water quality before red tides outbreak. In this paper, the monitoring system of red tide was designed by using the technology of the Internet of Things. In the system, the red tide was monitored by wireless sensors, and its geographic information position was oriented by GPS. Digital and analog sensors were connected to the mobile sensor module so that the system could monitor multiple water parameters, and could accurately provide the variation gradient of the salinity, temperature, flow rate, and chlorophyll. The data was issued by using C/S structure. The data and the user interface could be displayed, and the user' s interface was realized by ArcGIS Map. Practice proves that the outbreak of red ride can be accurately forecasted by using the monitoring system.%近海赤潮的频繁爆发对海洋环境和海洋经济产生了极大的破坏力,对赤潮的监测与预报尤为重要.为了能够实时快速地监测赤潮发生前的水质的变化情况,利用物联网技术,设计了近海赤潮环境的监测系统.在该系统中综合运用无线传感网络技术、嵌入式计算技术、移动通信技术、GPS技术,对赤潮发生的重灾区进行动态监控,移动传感模块可以与数字与和模拟类传感器相连接,可监测多个水体参数,能够准确的提供海水的盐度、温度、流速、叶绿素等参数的变化梯度.该系统采用C/S构架实施数据的发布和数据用户界面的显示及交互,利用ArcGIS Map实现用户的交互界面,达到对赤潮爆发灾情的预报.
