| Intelligent gateway is the smart home system in the management center,ga teway service software usually by hierarchical design,will be treated as each communication protocol of centralized in lower business logic.But due to the various equipment protocol,realize the same function but with different protocols equipment provided by the inconsistencies of the interface to the upper logic development bring development complexity,the communication protocol layer and business logic layer coupling increase;In addition,due to the smart home system dynamic characteristics,the demand space changing,peripheral devices turned on and off at any time according to the users’ needs,which requires the services of the running state and dynamic adjustment according to the environmental changes.Traditional intelligent household service software is not very good to adapt to the system characteristics,and the dynamic can’t very well in the service logic in expression and management,to the service logic added extra burden,make its loss of reusability,increased its development complexity.To solve the above problems,this paper puts forward a applicable to the characteristics of the smart home system gateway service software architecture,by designing the adapter artifacts and abstract data type encapsulating the diversity and complexity of the communication protocol,so as to provide top service abstract representations of the peripheral equipment and the function interface;Design the adapter artifacts related management unit,by the system according to the peripheral equipment real-time state of work,to create the adapter component instance and cancellation of the upper services needed to pay attention to and processing equipment switched on or off,and just focus on the business logic implementation.,on the other hand,based on dynamic software product line technology proposed dynamic configuration and characteristics of the model,based on the characteristics of peripheral equipment,intelligent service on or off,and according to the changing needs of the space of the smart home system dynamic reconfiguration.The adapter artifacts and abstract data types effectively removes the services and the underlying protocol coupling,intelligent peripherals registration,cancellation and the dynamic reconfiguration of the system,improves the reu sability of services,lower the development complexity.Experiments show that based on the proposed technique can effectively improve the efficiency of the development of smart home system,scalability,and robustness. |
