【摘要】 为解决传统网箱养殖水质检测周期长、实时性差、数据误差大、维修成本高等问题,设计了一种基于无线网桥与ZigBee进行数据传输的深海网箱养殖水质与环境监测系统。该系统主要通过水质传感器获取网箱内海水的温度、盐度、浊度、pH以及溶氧等水质参数,同时利用水下摄像机采集水中鱼群状况、水面环境信息等图像信息,并通过无线网桥将监测的水质参数与图像信息实时传输至岸基数据监控中心,由监控系统实时监测养殖环境参数变化,并且可以通过无线接入点向设备发送控制指令来进行相关操作,如通过控制图像采集设备的云台来实现对网箱水面或水下环境的监控。结果显示:采用该检测系统后,能实时传输图像信息和水质参数,并能实现实时远程控制;操控中心具有数据显示、历史数据查看、水质异常时声光报警等功能。该系统具有操作简便、响应快速、成本较低、可靠性高等优点,具有较好的推广应用价值。更多还原

【Abstract】 In order to solve the problems of long term,poor real-time detection,large data error and high maintenance cost of traditional cage culture water quality testing,a deep-sea cage culture water quality and environment monitoring system based on wireless bridge and ZigBee is designed.The system mainly uses water quality sensors to obtain water quality parameters such as temperature,salinity,turbidity,pH and dissolved oxygen in the cage,and uses underwater cameras to collect image information such as fish condition and environment information in the water.The monitored water quality parameters and image information are transmitted to the shore-based data monitoring center in real time through the wireless bridge,and the monitoring system monitors the changes of the culture environment parameters in real time,and can send control commands to the device through the wireless access point to perform related operations.For example,the monitoring of the water surface of the cage or the underwater environment is achieved by controlling the pan/tilt of the image acquisition device.The result shows that after using the monitoring system,the image information and water quality parameters can be transmitted in real time,and the remote control can be carried out in real time.The control center has data display,historical data view,sound and light alarm in case of abnormal water quality,and other functions.The system has the advantages of simple operation,fast response,low cost and high reliability,and has good promotion and application value.更多还原
