Design and implementation of marine main engine edge computing equipment
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.
