摘要
实时监测是实现内孤立波预警的前提和基础。文章根据内孤立波过程海流的特征,提出了一种基于天通通信的内孤立波监测系统。该系统在浮标端搭载海流计进行剖面海流的实时观测,并将数据进行分帧传输和丢包重传,保证观测数据的可靠实时传输;在云端采用数据接收存储和内孤立波识别功能解耦的设计,在实现内孤立波监测的同时,降低模块间的交互调用,提高系统运行的稳定性。海上工程应用结果表明,该系统运行稳定,浮标端数据采集率达100%,云端有效数据接收率达95.1%,且系统自动化内孤立波监测的功能有效地提高了内孤立波识别效率,保障了目标海域的施工安全。
Real time monitoring is the prerequisite and foundation for internal solitary wave(ISW)warning.This article proposes an ISWs monitoring system based on the Tiantong communication,and the ocean current characteristics of ISW processes.The system is equipped with current measuring instrument at the buoy for real-time observation of profile currents,and transmits data in frames and packet loss retransmissions to ensure reliable and real-time transmission of observed data;on the cloud platform,the system separates data reception and ISWs identification functions,reduces the interaction between modules and improves the stability of system.The application results of offshore engineering show that the system operates stably,with a data acquisition rate of 100%at the buoy and an effective data reception rate of 95.1%at the cloud.The system’s automated ISWs monitoring function effectively improves the efficiency of ISWs recognition and ensures the construction safety of the target sea area.
