Design and implementation of ship shore power data analysis system based on Doris data warehouse

Ship shore power technology is an effective means to achieve energy conservation and emission reduction for water transportation. In order to ensure the scientific usage of ship shore power and optimize the layout of ship shore power piles, a ship shore power data analysis system based on the Doris data warehouse technology is designed and implemented. This system can realize a real-time data statistics and query based on Doris. It realizes the visual display based on the back-end and front-end separation technology. The front-end requests data through Axios, and the back-end returns the query data with the JSON format. Maps and charts are displayed based on the Echarts and Mapbox tools. The system has been applied in the maritime supervision, and provided the data support for the decision-making of ship shore power management.
