无线分布式渔业资源声学监测系统

摘要

Due to the disadvantages of low efficiency and uneasiness to expand the traditional way of acoustic monitoring of the fishery resources,a wireless distributed acoustic monitoring system was designed.The system was composed of some distributed monitoring points,and each monitoring point was composed of a ship,a fish detector,a computer,a GPS,a wireless AP and an antenna.A main control method of the application program was designed,and the system was controlled by the main control terminal,so that each monitoring point was operated in a coordinated operation without interfering with each other.The application program automatically maintained the consistency of the data of each monitoring point,and synchronized the status and the monitoring data of each monitoring point,and displayed the monitoring data and geographic information in the form of GIS.Several distributed monitoring points worked together to increase the instant monitoring range,and improved the monitoring efficiency and the accuracy of the data.The use of wireless network and distributed system architecture allowed configuring the number and the location of monitoring points flexibly according to different water environments and monitoring requirements.%针对传统走航式的渔业资源声学监测方式效率低、不易扩展的缺点,设计一种无线分布式渔业资源声学监测系统.系统由多个分布式的监测点组成,监测点之间通过无线网络进行通信,每个监测点由船、鱼探仪、计算机、GPS、无线AP及天线组成.设计应用程序的主控端机制,由主控端对系统进行整体控制,使各监测点可以协同运行,互不干扰.应用程序自动维护各监测点的数据一致性,保障各监测点的状态及监测数据同步,以GIS形式展示监测数据与地理信息.多个分布式的监测点协同工作,增大瞬时监测范围,提高监测效率及数据的准确性,无线网络的应用和分布式的系统结构,允许根据不同的水域环境和监测需求灵活配置监测点的数量及位置.
