Research On Monitoring Systerm And Capacity Optimization Configuration Method Of Unmanned Photovoltaic Charging Station

Today's social resources are in short supply and the environment is deteriorating,resulting in many problems.At the same time,large-scale use of non-renewable resources such as coal,oil,and natural gas has led to global warming,and large-scale melting of glaciers has occurred in the Antarctic and Arctic.It has had disastrous consequences for the natural environment.Various countries are increasing investment in scientific research to develop new types of clean energy to reduce damage to nature.Solar energy has attracted much attention as a clean and renewable energy source.Due to the rapid popularity of electric vehicles,large-scale construction of electric vehicle charging stations with solar energy as the main energy source has begun.Intelligent monitoring and management of solar charging stations is a prominent problem.Therefore,based on the analysis of the composition structure of photovoltaic charging stations,this paper designs a photovoltaic charging station monitoring system that can meet the unattended and intelligent monitoring of photovoltaic charging stations based on actual engineering needs.The charging station administrator can observe the operation status of the charging station in real time in the remote monitoring center,the user can complete the charging fee settlement,and the maintenance personnel can complete the query of historical operating data.Mainly complete the following work:1.The composition structure of photovoltaic charging station is analyzed,and the system model of solar charging station is designed.2.Through the analysis of the demand for unattended photovoltaic charging station monitoring,the design work of the underlying hardware system for photovoltaic charging station monitoring is completed.The bottom layer sensor is controlled by the MCU to complete the collection of the electrical data and environmental data of the charging station.Through the ZigBee self-organizing network technology in the station,the operation data of the multi-channel charging piles are transmitted and summarized,and the collected data is sent to the cloud database for storage analysis through the 4GDTU module.At the same time,the development of the human-machine interface in the station was completed through the USARTHMI configuration screen to meet the needs of users to check the charging status and repair personnel to complete the fault analysis.3.Based on MFC,the host computer of the charging station monitoring system is developed.The host computer monitoring system includes:first,access to cloud data,view the operation data of the charging station collected by the underlying hardware system sensors;second,visit the TLINK terminal monitoring system to view the charging station Long-term operation data curve.Third,when data overruns and fires occur in the charging station,alarm information is pushed to the administrator and maintenance personnel4.Based on the research on photovoltaic charging stations,theoretical research was conducted on the capacity planning of composite energy charging stations in the future.A capacity optimization configuration model was established with the objectives of maximum renewable energy utilization rate and minimum investment cost,and the model was solvedIt has been verified that the unattended photovoltaic charging station monitoring system designed in this paper can realize the functions of collecting,transmitting,storing,and analyzing the operating data of the charging station,and can satisfy the intelligent management of the charging station by the administrator.The expected design effect is achieved.
