Research On Visual Analysis Method Of Energy Spatial And Temporal Data

Visualizing massive data of energy consumption quantity can be visually presented to the user in a graphical way which is for the properties of energy consumption data generated in real time of energy supply equipment.Providing a powerful guarantee for the visualization analysis of energy consumption supply data.The supply of data has become increasingly complex with the development of smart cities.Showing present supply situation information and monitor data anomalies based on energy consumption supply data is the main task of supply process security and stability.According to the problem of the existing visualization system cannot be showing well the supply line and multi-dimensional hierarchical information,so this thesis firstly summarizes the visualization techniques of spatiotemporal data and energy consumption supply.Then it proposes a visualization method based on the detail level of multidimensional spatiotemporal data.And it also makes a visual design to the energy consumption data in the city.A set of visualization analysis system for the energy consumption supply data is proposed to make it convenient for the managers to view and analyze the supply data at the same time.It can assist managers to analyze and explore the abnormal information caused by energy consumption by showing the energy consumption spatiotemporal data visualization graphics in the system and providing rich interaction.So it can finally verify the effectiveness of the system through the actual cases and professionals.The main work of this thesis is as follows:1)Summarizes and analyzes the spatial and temporal data visualization method and energy consumption supply data visualization.Firstly,the related work of spatiotemporal data visualization is summarized from the perspective of time and space respectively.Multi-dimensional spatiotemporal data visualization technology is combined with energy consumption supply data technology through multi-view visualization method.And provides a theoretical basis for energy consumption visualization system.2)Summarizes the multi-level progressive visualization method according to the multidimensional spatial and temporal data.It summarizes the visualization techniques under different dimensions based on LOD level of detail visualization technology.Put forward to the hierarchical structure division of hydropower through the visual analysis of multi-dimensional spatiotemporal data.And the corresponding visual view is designed for the numerical information of water and electricity.3)Presents a set of visualization analysis systems for energy consumption data with multi-dimensional spatiotemporal data.According to the spatial and temporal characteristics of energy consumption data and takes the data of water and electricity consumption in the city as an example.Determining detailed requirements of the system is based on the discussions with relevant department experts.Then the corresponding visual graphics are designed through the processing and analysis of the data of urban power supply and water supply in mountain-type scenic spots.Showing the spatiotemporal characteristics of energy consumption supply data by different dimensional maps and other visualization technologies.Finally,the usability of the system is proved by detailed case analysis and the effectiveness of the visualization system is verified by the user evaluation.
