Design Of Indoor Electricity Center Sensing Platform Based On Integration Of Terminal And Cloud

With the constantly emerging of the new network applications and services,centralized computing and storage as the main characteristics of cloud computing has been difficult to meet,such as the Internet of things,wisdom,smart grid technology and application of urban development needs,in order to overcome its limitations,such as edges computing,mobile computing and proximal cloud computing model is becoming more and more attention,and in combination with current with the rapid development of intelligent electricity technology and the rapid popularization of smart appliances,indoor electric safety is more and more attention,the traditional acquisition terminal make the cloud computing pressure surge because all the data will be sent to cloud.To deal with it,this paper proposes a highly reliable and real-time electricity perception service combining with the existing hardware terminals.This architecture has the following advantages: first,it applies the edge computing theory to decouple the data transmission and data presentation with deploying them separately,so as to effectively reduce the pressure on the central server.Secondly,the architecture is based on the long-connection communication scheme,using the cache database to make the system with strong real-time performance,and adopts the configuration center,so that the platform can flexibly respond to the needs of various electricity scenarios.Finally,based on this architecture,the deep collaboration between the perception terminal and the cloud in network,business,application and other aspects is promoted,and the system has high agility.Based on the above architecture,this paper designs and implements an indoor power center perception platform based on end-cloud integration.The platform designs "data transmission middleware" module and "central perception service" module for data transmission and data presentation tasks.Among them,"data transmission middleware" adopts TCP protocol to access a large number of hardware sensing devices,and "central sensing service" module uses database,Web and other technologies to display power consumption data in real time.Through the overall test of the platform,it can fully meet the expected demand,and so far,the platform has been applied to many electricity places such as universities,hotels,homestays and residential communities,with stable operation and good results,confirming the social value and practical significance of the platform.
