具有粒径计数功能的可视化浮游生物拖网系统

Visual biological trawl system with plankton spectrum function

针对拖网在海洋环境监测中的应用,设计并实现了一款具有粒径计数功能的可视化浮游生物拖网系统,通过使用搭配水下照明设备的高清摄像机以及激光浮游生物计数器收集浮游生物图像及粒径谱数据。该系统使用千兆以太网、光纤网络和TCP/IP的实时传输协议将水下采集的数据发送到甲板视频监控平台,可以接收、显示、存储生物图像和传感器数据,并控制摄像机和灯的工作状态。该系统所使用的高清摄像机和千兆以太网通信架构使其能够实现高品质的图像效果,激光浮游生物计数器使其能够实现水下浮游生物粒径谱实时采集,以获得便捷使用的效果。

For trawl applications in the marine environment monitoring, this paper designs a visual plankton trawl system, by using underwater lighting equipment with HD cameras and a laser optical plankton counter to collect image, video and plankton data. The system uses Gigabit Ethernet, fiber- optic network and TCP / IP protocol for sending real- time transmission of data to the deck video surveillance platform that can receive, display, storage video, sensor data, and control the devices working status. The system owns HD cameras and Gigabit Ethernet communications architecture so that it can be used to achieve high- quality video display, as well as laser optical plankton counter achieves real- time data acquisition, so as to achieve convenient and fast performance.
