The Design And Implementation Of Intelligent Terminal Cloud Service Platform Based On SOA

With the development of IOT technology,more and more intelligent terminal equipments production that can meet people's living and producing have emerged in large numbers,and how to manage these equipments effictivly,quickly and cheaply has become an urgent problem for intelligent terminal manufacturers.Therefore,this paper constructed an open Paa S cloud platform based on SOA for intelligent terminal management and control,making a large number of intelligent hardware devices in different types,in different manufacturers access to the service platform quickly to achieve data processing for equipment and remote real-time control operation.The main content of this dissertation is described as follows:(1)In the system architecture,aimed at cloud computing and intelligent terminal,we put forward a hierarchical model of SOA that dividing the system into Iaa S layer,Paa S layer,Service layer and Access layer.Iaa S layer provides cloud infrastructure services,Paa S layer provides customized service platform,Service layer integrates universal service components for intelligent terminal applications and Access layer is used to solve the access problem of terminal equipments and users' APP.(2)In the communication mode,we designed the communication format of REST based on HTTP protocol.The communication model of REST style has the characteristics of loose coupling,cross platform and stateless that very suitable for distributed computing and cloud environment.The communication mode designed in this paper can conveniently realize the service location,the request authentication and the information bearing.In addition,we also applies the TCP long connection mode for equipment operation management.(3)On the realization of key technology,we realized the equipment management and control service with MINA communication framework,realied data storage function with My SQL and No SQL,realized UDS framework with jettey,realized UDS deployment on Paa S layer with docker container technology and realized service registration and discovery with Nginx and ETCD.Finally,we set up an intelligent terminal with STM32 and Hanfeng Wi Fi module,that has data acquisition and equipment operating functions.We proved that the platform is high availability and convenient to access by asseccing the terminal to the platform and making it work.
