摘　　要：针对智能家居系统特殊的应用场景,设计一个能够将异构的智能家居设备进行无缝集成的智能型网关.首先对智能家居的网关进行模型设计,设计了网关的体系结构模型;然后对网关的硬件进行设计,设计了基于ARM Cortex-A8内核的主控模块、基于CC2530的Zig Bee模块、电源模块和无线通信模块等.对网关软件方面,主要设计了软件整体结构、主控程序流程、异构新加入设备的检测流程,同时设计了基于服务的任务调度与恢复算法;对网关的安全与隐私进行了研究,提出了分层访问控制算法和安全信息传输方法.最后对网关的组网性能、实时控制性能和数据传输性能等进行了测试,给出了不同协议下测试得到了数据丢包数曲线;同时,对服务任务调度与恢复算法进行了对比测试.通过测试得到本文设计的网关具有一定的先进性和实用性.For specific application scenarios of smart home systems,it is very necessary to design an intelligent gateway for seamless integration of heterogeneous devices in smart home. At first, this paper designed a model of smart home gateway as well as its systematic architecture model. And then, the hardware of the gateway are designed ,including the main control module based on ARM Cortex- A8 kernel, the ZigBee module based on CC2530 ,power module and wireless communication module. As for the software of the gateway, this paper mainly designed the overall structure, software program flow control, the supervising system for the new added device as well as the system for task scheduling/recovery algorithm based on service. Additionally this paper probed into the security and privacy of the gateway, and proposed the hierarchical access control algorithm and secure information transmission method. Finally, we tested the performances of the gateway, real-time control and data transmission, and provided data packet loss curves under different protocols. And we conducted a contrasting test on the task scheduling and restoring algorithm. The result of the testing proves the advancement and practicability of the design of the gateway proposed in this paper.
