Research On Visual System Of Electric Vehicle Charging Pile Based On WebGIS

With the global warming,the non-renewable resources of oil,coal and natural gas are gradually drying up,so as environmental degradation and other factors is prompting the rapid development of emerging energy technologies.Electric vehicles can reduce carbon emissions,and protect the environment,becoming a trend of development.Our government adapts to the requirements of the times,and vigorously develops electric vehicles and related industries.The charging pile is the core supporting facilities of electric vehicles,which plays a key role in the development and popularization of electric vehicles.The charging pile is like the petrol station of the traditional automobile,and is the national infrastructure construction.How to effectively layout the number and position of the charging pile,so that it is complementary to the development of electric vehicle and optimized allocation is a major issue.With the popularization of internet technology,the progress of large data theory and algorithm provides a good way for effective and efficient allocation of charging piles.Information visualization is the visual representation of data,its essence is the optimization of data presentation methods based on computer graphics,image processing as the basis integrating a variety of technologies.The key data of the charging pile is the state parameter and the access quantity.Based on WebGIS Network geo-information data,as well as based on the status information of the charging pile,the visualization technology is organically fused;the data information is uploaded to the cloud,so that the depth mining of data information is carried out to optimize the position and quantity configuration of the charging pile,then focus on the fault information of the charging pile and facilitate the user's multipath access query which is the content and significance of this thesis.This thesis expounds the technology of realizing the visualization system of electric vehicle charging pile,such as WebGIS technology,ArcGIS API technology,GPRS technology,RFID technology and other technologies,in order to establish a theoretical data link and design intelligent charging pile platform,with DSPTMS320F28335 as the processor,integrate RFID module and GPRS module,design AC voltage,DC voltage and AC/DC current signal acquisition conditioning circuit,write hardware platform system program,so that the GPRS transmission of analog and switch data is realized,as well as the welding and testing of the test machine is completed.Build the server network;design the upper computer application layer software.The real-time data received is visualized and the WebGIS charging pile visualization system is realized based on the free map JavaScript API of the experimental sample.Take Lanzhou city area and Lanzhou new area as visualization area,select representative locations as the experimental sample point monitoring end of charging piles,The real-time data of the simulation field monitoring terminal is integrated into the monitoring center network through GPRS wireless transmission,and the system realizes the real-time release system such as the charging voltage and the charging current of the charging pile through the data visualization processing and the open source GIS data platform.For the design of the system platform for research and testing,verify the real-time validity of the data link,and the intelligent charging pile query control at application layer.The construction of electric vehicle charging pile has been rapidly advancing in the whole country,and it has scale in the early 2020,but it has not yet reached the application of intelligentization.The research innovation of this thesis lies in the wireless data link through GPRS,the electric charging pile information data combines with the WebGIS technology to establish the cloud database,which provides the data base for the position,quantity,the fault maintenance and the user inquiry of the charging pile continuous construction.
