摘要
随着信息技术的发展以及智能船舶规范的完善,智能船舶虽未成熟但也得到迅速发展.而智能化最需要数据、算法和计算能力这三方面内容.船舶主机作为动力来源,其状态监测和故障诊断所需的高采样率信号会带来数据量庞大、传输链路带宽不足等问题.因此,设计一种集数据采集、船舶主机信号数据特征分析、网络通讯等功能一体的主机边缘计算设备,并完成了边缘设备与边缘服务平台之间的数据交互和与物联网平台的测试.实验结果表明,船舶主机边缘计算设备可以准确采集数据并进行数据预处理,并通过TCP协议上发,一定程度上减轻了本地及云端计算设备的计算压力,为后续的健康监测或故障诊断等数据分析流程提供了实时准确的数据来源.
Abstract
With the development of information technology and the improvement of intelligent ship specifications,intelligent ships have developed rapidly although they are not mature.And the most needed aspects for intelligence include data,algorithms,and computing power.As the power source,the high sampling rate signals required for condition monitor-ing and fault diagnosis of the main engine of the ship will bring problems such as large data volume and insufficient trans-mission link bandwidth.Therefore,this paper studies and designs a host edge computing device that integrates data acquisi-tion,ship host signal data feature analysis,network communication and other functions,and completes the data interaction between edge device and edge service platform and the test with IoT platform.The experimental results show that the edge computing device of the ship host can accurately collect data and preprocess the data,and send it up through the TCP pro-tocol,which alleviates the computing pressure of local and cloud computing equipment to a certain extent,and provides a real-time and accurate data source for the subsequent data analysis process such as health monitoring or fault diagnosis.
