| 摘 要： | 为克服离岸深水网箱群养殖水域环境和鱼群安全日常监测不便的问题,提出了一种集中式深水网箱群鱼群状态远程监测系统。采用水声多波束探测技术、多路信号处理技术设计了远程探测节点,用于扫描各深水网箱内部空间;采用虚拟仪器技术设计了本地监控中心,便于用户集中控制远程探测节点、查看网箱探测结果;采用GPRS无线数据传输技术构建了远程、实时的指令和数据传送通道。监测系统样机在福建省泉州市围头深水网箱养殖现场进行测试,结果表明:系统设计合理,操作方便,性能稳定、可靠,能够准确及时地反馈养殖环境变化情况和网箱鱼群状态,减轻养殖工作量。

| Abstract: | In order to monitor the aquatic environment and fish state in offshore aquaculture cage farm daily, a centralized remote monitoring system for bred fish was developed. The system was composed of remote detecting node (RDN) and local monitor and control center (LMCC). RDN based on the techniques of multi-beam detection and multi-path signal process was placed in the center of a cage to scan the inner cage and measure the aquatic environment. LMCC based on LabVIEW was placed in the office to manage all the remote detecting nodes remotely and show fish state. The communication between LMCC and RDN depended on GPRS wireless data transmission technology. The system prototype was tested in the field of offshore aquaculture cage farm in Quanzhou, Fujian province. The results show that the system is reasonable design, simple operation, easy placement, and robust under different environmental conditions. It can real-time monitor the aquatic environment and fish activity remotely, provide users with a variety of information such as fish amount, fish growth in the offshore fish cage, and give an alarm in the time when net clothing damage or fish escape. |
