智能家居的六域场景模型系统设计

Design of Six-domain Scene Model System for Smart Home

针对目前社区和家庭联动场景无法满足灵活联动服务的问题,本文设计了基于六域场景模型的智能家居场景引擎平台。该系统基于中国移动数字家庭Andlink连接体系,在社区和全屋设备联动规则的基础上,引入人、空间、时间、环境、服务五大元素,给场景规则添加全面的上下文信息,让规则执行可以更加智能化;通过WiFi、NB-IoT、ZigBee3协议实现场景平台连接设备双向通信;通过事件匹配、条件检测、指令生成完成场景执行引擎流程;通过Kafka二级消息服务器处理、Redis缓存数据、MySQL持久化数据实现基于六域场景模型的场景联动设计;预置丰富的智能场景推荐模板,该场景模板可后台可视化生成,解决了用户手动创建场景时操作不便、体验较差的问题。

Aiming at the problem that the current community and family linkage scenarios cannot satisfy flexible linkage services,a scenario engine platform for smart home based on the six-domain scenario model is designed.Based on the China Mobile digital home Andlink connection system and the rules of community and whole-house equipment linkage,the system introduces the five elements of people,space,time,environment,and services,and adds comprehensive context information to the scene rules,so that the rule execution can be more intelligent.Through WiFi,NB-IoT,and ZigBee3 protocols,two-way communication between the scene platform and connected devices is realized.The scene execution engine process is completed through event matching,condition detection,and instruction generation.Through Kafka secondary message server processing,Redis cached data,and MySQL persistent data,the scene linkage design based on the six-domain scene model is realized,and a rich intelligent scene recommendation template is preset.The scene template can be generated visually in the background,which solves the problems ofinconvenient operation and poor experience when manual creation of scenes by users.
