Key Technology And Implementation Of Systerm For Electric Power Management Service Based On IoT

With the development of science and technology,the people's life style is moving closer to the information technology,and the living standard is also being improved rapidly.In order to meet the need of the masses,the problem of energy consumption has been paid more and more attention to.In recent years,the state has issued various types of documents on the electricity reform,to try to adjust the current electricity system and management system,in order to create an open,transparent and efficient electricity environment.To deeply understand the status of power management services,through the analysis of networking equipment,acquisition terminal,communication protocol and electricity services application platform framework,the research based on the IoT electricity monitoring and management services was conducted.In this paper,firstly,a design scheme based on the IoT electricity service system was presented.The current electricity acquisition terminal,communication way and communication efficiency were compared.The core hardware chip selection applied in the electricity service system was analyzed.The research content of the communication level mainly included: The current fashionable Lora module was improved.The reliable communication distance and stable transmission rate of Lora module was measured in the actual environment of the meter installation.The best application environment with the smart meter of Lora module was studied.Under the stable and reliable premise,the highly cost-effective communication scheme was determined according to the different installation environment.In this paper,the compared communication schemes were as follows: RS485 communication,WIFI communication,GPRS communication and Lora(a kind of micro power wireless communication module)communication.The edge computing service was fused into the electricity service system.In the network edge area near the data source and the electrical area,using local computation and local storage service,the corresponding pretreatment,simple analysis and filtering on the data were conducted in the local edge,to enhance theoverall performance of the general service of the electricity services background.From the view of business logic,the detailed logical function division on the Edge Server local server and cloud general server in the electricity service system was carried out.The business process,function service and business logic requirement were in-depth investigated and analyzed,to provide a guarantee of practicality and product process of the electricity service system.The overall structure of the electricity service system could be mainly divided into three parts: the smart meter acquisition layer,the communication channel layer,the local edge computing service layer and the power management service layer.Each part was detailedly elaborated and testified.The highlights in the electricity service system were as follows: It supported the highly intensive data collection,and the data reporting way of each scheme was active reporting;It supported the calculation of multi rate electricity,Internet power monitoring,overload and dangerous load identification,leakage protection electricity theft alarm,user autonomous network purchase of electricity,one-key output of electricity report and other practical functions.Finally,the power acquisition terminal and the power service master station system software based on the HT501 X chip were functionally tested to verify the high reliability of the system.
