WLAN技术在家居智能化中的应用

Applications of WLAN Technology in Home Intelligence

目的针对智能化家居的特点,应用无线网络技术构建家居智能化网络系统并研究系统可靠性和安全性的解决方法.方法通过对比无线网络的各种技术标准,选择了适合于构建家居智能化网络的ZigBee技术,以此搭建系统组网模型,设计系统软件工作流程,并分别采用DSSS通信技术、差错控制和RADIUS、非对称加密算法解决系统可能存在的可靠性和安全性问题.结果利用无线网关和外部网络连接构成的智能化家居网络,可提供集中和异地的数据通信,使信息在家庭内部和外部之间充分流通和安全共享.结论采用无线网络技术实现的家居智能化网络系统具有有线网络无法比拟的灵活性和可扩展性,给人们的生活带来了更多的便捷、舒适与高效率.

Home intelligent network system is constructed by applying WLAN technology according to the specialty of intelligent home and its solve-method of system reliability and safety are studied. By contrast all kinds of standards of WLAN, the ZigBee technology suitable for home intelligent network is selected. Model of system network composition is structured as well as work procedure of system software is designed based on the ZigBee technology. Furthermore, DSSS communication technology, error-correction, RADIUS and asymmetric cryptographic algorithm are adopted to resolve the system problem of reliability and safety that may exist. The result shows that the intelligent home network achieved by connecting of wireless gateway and outer network can sustain digital communication of center and different terra. And the information can circulate fully and share safety inside and outside of room. The authors therefore draw the conclusion that the flexibility and scalability of the home intelligent network system that implemented by introducing WLAN technology is incomparable to wire network. Further convenience, comfort and high efficiency are brought to people's life.
