Design And Implementation Of Remote Battery Storage System Data Acquisition Base On IoT

In the past 10 years,the research and development of energy storage system,especially lithium battery energy storage technology,has been attracting the attention of domestic and foreign research institutions and energy departments.Under the guidance and help of the development of new energy vehicles,lithium battery technology has been greatly improved in terms of density,safety and other performance,and the cost has been decreasing year by year.Therefore,lithium battery energy storage technology has gradually become the focus of the development of energy storage industry,and practical engineering applications in various places have also received great support.Energy departments and private enterprises all over the world are focusing on the development of battery energy storage.Energy storage industry is an important link in the development of smart power grid in China and an important supporting technology for the plan of "Peaking Carbon Dioxide Emissions" and "Carbon Neutrality".Therefore,it is an irresistible trend to develop energy storage industry vigorously.The data acquisition and monitoring system of the battery energy storage system is an important guarantee means for the operation of the battery energy storage system.The research on the remote monitoring system based on the cloud platform of the Internet of Things has become an important direction,which has practical significance to solve the current engineering practice problems.The remote data acquisition system for battery energy storage realized in this paper is built on the cloud technology platform of Microsoft Internet of Things.This paper first analyzes the structure of battery energy storage products,B Company’s functional requirements for battery energy storage data acquisition system and the flow process of battery energy storage system products,and uses UML tool modeling to complete the demand case model for the remote data acquisition system of the battery energy storage system.On the basis of requirement analysis,through the analysis of general Internet of Things system and cloud technology platform,the software outline design of battery energy storage remote data acquisition system based on Microsoft cloud technology Internet of Things platform(Azure Io T)is completed,including the physical topology of the system and the overall software architecture.This paper focuses on the Azure Io T service to realize the data transmission(transmission protocol selection)between the local collector and the cloud gateway,the cloud data storage scheme and the data flow analysis and processing of the three main technical points.After the overall outline design of the subject is completed,the database of the remote data acquisition system is detailed outline design and logical design according to the database design steps by using the data modeling method of IDEF1 X,and the data modeling of the remote data acquisition system of the battery energy storage system and the transformation of the relational mode are completed.Finally,the Web interface of the acquisition system is completed,and the problem of long response time in the application of the system is solved by preloading and other strategies.
