基于物联网的船舶航行安全监控系统

Ship navigation safety monitoring system based on Internet of things

传统船舶航行安全监控系统在复杂海域中,对船舶航行吃水差监控误差较大,对此基于物联网络技术设计船舶航行安全监控系统。以中央处理单元为核心,建立船舶自由度运行测试平台,辨识船体吃水差,基于物联网通信端口,建立物联网络通讯终端,传输船体航行信息,最后利用信号叠加原理应用傅里叶分析算法,消除波浪及船体摇摆对船体吃水差的影响,实现对船体航行吃水差高精度安全监控。实验数据显示,设计的安全监控系统,相比较传统安全监控系统,在海深1 km以内,吃水差监控结果误差减小0.75 m,在海深1 km以上海域,吃水差误差减小0.5 m,可以实现吃水差高精度监控。

The traditional ship navigation safety monitoring system has a large error in monitoring the ship's navigation draught difference in complex sea areas. For this, the ship navigation safety monitoring system is designed based on the Internet of things technology. Central processing unit as the core, build degrees of freedom to run the test platform of ship, hull trim, identification based on Internet communication port, set up united network communications terminal, the transmission of hull navigation information, finally using the signal superposition principle using Fourier analysis algorithm, eliminate the waves and hull swings influence on hull trim, sailing for the hull trim high-precision safety monitoring. Experimental data show that design of safety monitoring system, compared with the traditional security monitoring system, deep in the sea within 1 km, trim monitoring result error reduce 0.75 m, deep in the sea more than 1 km waters, trim error reduce 0.5 m, can realize the trim high-precision detection
