基于机器艇与ZigBee的湖泊水质监测系统设计

摘要

湖泊是地表水资源的重要载体,为了全面、实时、高效地监测湖泊水环境,设计一种湖泊水质自动监测系统尤为重要;多艘机器艇搭载水温、pH值、溶解氧等传感器,在湖面上组成基于ZigBee的无线传感器网络进行数据采集;水质数据通过无线传感器网络传输到上位机进行分析显示;基于GPS和姿态传感器的运动控制算法实现了机器艇自主航行到指定监测点的功能;实验结果表明,系统实现了对湖泊水质的较大范围实时监测,能满足实际应用需求.%In order to monitor the lake water environment in a comprehensive,real-time and high efficient way,it is very important to design a lake water quality automatic monitoring system.Many robot boats carry water temperature,pH,dissolved oxygen sensors and construct ZigBee based wireless sensor network for data acquisition.The water quality data is transmitted to the host computer through the wireless sensor network for analysis and display.The robot boat can autonomously navigates to the specified monitoring point using GPS and attitude sensor based motion control algorithm.The experimental results show that the system realizes the automatic real-time monitoring of the lake water quality to satisfy the practical application requirements.
