Research On The Key Technologies Of Dynamic Configuration In Intelligent Gateway

As the smart home management center,intelligent gateway is responsible for the overall management of the entire smart home system,so how to design and implement a simple home intelligent gateway has become a key issue in the field of smart home.By now,the domestic and overseas scholars have made great progress in the study of home intelligent gateway,but there are still some problems to be solved as follows:Firstly,the research of home intelligent gateway basically stays in the customization stage,only supporting the specific equipments and services,so it doesn’t have the characteristics of universality;Secondly,as a typical dynamic system,the demand space of the intelligent home system is constantly changing,which requires the service running state with the environment changes and dynamic adjustment,the existing home intelligent gateway can not give a preferable realization of the dynamic system.Considering these two problems existing in home intelligent gateway,this paper combines the idea of DSPL(dynamic software product line)with the dynamic configuration technology,and introduces the concept of dynamic configuration technology into the research and design of home intelligent gateway.Based on the FODA(software-oriented feature analysis)method,a dynamically configurable feature model is built for the family intelligent gateway,and a dynamic configurator is designed based on the dynamically configurable feature model which is combined with the dynamic configuration technology.At the same time,by adding the dynamic configurator in the architecture of the home intelligent gateway to realize the self-configuration and dynamic of the systems,enhanced the reusability and scalability of the home intelligent gateway.It is of great significance for the development and popularization of the smart home.The main work of this paper can be epitomized as follows:1.The concept of product line feature model,product feature model and dynamically configurable feature model were proposed.The product configuration process was described by designing the FDL(feature description language).And by combining the DSPL with the feature model,this paper came up with a dynamically configurable feature model which can be recognized by home intelligent gateway.2.The design scheme of dynamic configurator were put forward.In the design of the home intelligent gateway,the dynamic configuration was introduced,and the dynamic configuration algorithms of the home intelligent gateway were designed when a new device is added,a device is deleted,a service is opened and a service is closed.3.A specific implementation of the dynamic configurator was proposed.By analyzing the principle of adapter pattern,observer pattern and simple factory pattern,the idea was applied to the realization scheme of dynamic configurator.And through the study of specific cases of smart home to complete the feasibility of the proposed program validation.4.The dynamic configuration technology of the product line features model modeling method,dynamically configurable feature model modeling method,the configuration language and the dynamic configuration algorithms were further studied.
