摘要: |
目前在智能家居领域,还没有相关的组织机构提出过一套统一的协议标准,各个厂商在设备交互上都有着各自的通信模式与协议标准.这增加了异构网关软件框架设计的复杂性和局限性.使用Linux内核提供的一套总线注册管理接口,在Linux下自行注册维护一条虚拟总线,将物理设备驱动挂接在该虚拟总线上,将通信协议的细节设计放置在底层适配器中,使得异构网络的融合更加自然.同时,基于Linux总线来设计智能网关系统的驱动层,可以让应用层的设计接口统一、逻辑清晰;使底层硬件设备的入网也变得更加便捷,层次分明. |

Abstract: |
Currently,in the field of smart home,there is no relevant organization that yet has proposed an unified protocol standard.It increases the complexity and limitations of heterogeneous gateway software framework design that different vendor′s devices have different communication mode and protocol standards.In this paper,a serial of interfaces are provided by Linux kernel,and a virtual bus is registered under Linux.The physical device drivers are able to connect to the virtual bus.The detailed designs of the communication protocol are placed in the underlying adapters,making the integration of heterogeneous networks more natural.At the same time,designing the intelligent gateway system driver layer based on Linux bus can let the application layer be more unified and clear logical.And it also let the hardware access network become more convenient and distinct. |
