Charging Pile Control And Background Management System Based On GPRS Communication

In recent years,China's electric vehicle industry has maintained a rapid growth momentum,China's automobile ownership has increased year by year.Although growth has slowed in recent years,there has been an absolute increase in the total amount.As a power supply device for electric vehicles,electric vehicle charging pile is an important tool for the development of electric vehicles,and its importance is self-evident.But also achieve better economic benefits and environmental protection functions.It can also speed up the pace of building green cities and smart cities.The charging pile system and management system of electric vehicle are studied in this paper.The purpose is to design a practical and expanding charging-pile data management system.First of all,according to the design requirements of electric vehicle charging pile,the whole system is divided into hardware design and software design.Firstly,this paper analyzes the hardware design requirements of the charging pile of the electric vehicle,and puts forward the modular design strategy,including the core control module,communication module,RF module,metering module and so on.The core board uses the STM32,and communication module adopts SIM900 GPRS module.The volume;RFID module and measurement module due to practical application,individually designed to adapt to different scenes of the charging pile design requirements;the final design of the circuit of the power supply module MP2359 power chip based on the GPRS for core module and power module;finally introduces and design of charging interface.As a starting point,this paper designed a charging-pile data management system.The function of the utility model is to arrange and store all kinds of data collected by the charging pile of the electric vehicle during the charging process.The management system of this article is based on SQL Server 2008.SQL Server 2008 is published on the Microsoft data platform,which can organize and manage any data.Data from structured,semi-structured,and unstructured documents can be stored directly into the database.And use C#.NET to design the host computer management interface,which can be conveniently and quickly operated on the PC side...
