摘　　要：近年来,物联网智能硬件技术高速发展,增强了以智能家居行业为主的对物联网场景下设备智能控制的需求.本文分析了现有的情景建模方法与设备智能控制框架,基于家居情景活动特征,提出了基于对象与属性图模型的情景建模方法,以适用物联网计算资源有限的场景;设计了智能家居交互的规则控制、模式控制和语音控制方式,使用推理引擎将情景感知数据映射到设备控制服务以实现系统的自动控制;提出了物联网下基于情景感知的智能控制系统框架;考虑用户行为习惯,引入了用户偏好这一情景概念以提供个性化的服务.性能测试表明基于对象与属性图模型的情景建模方法与智能控制系统,相比本体建模的控制方式具有更快的系统响应时间.In recent years,the rapid development of Internet of Things( IoT) and smart hardware technology has increased the demand of smart control of devices in the IoT scenario,mainly in the smart home industry. The existing context modeling method and the framework of device smart control are analyzed. According to the characteristics of household scenario activities,a new context modeling method based on object and attribute graph is proposed to apply to IoT scenarios with limited resources. Rule control,mode control and voice control approaches of smart home interaction are designed. An inference engine is used to map the data of contexts awareness to the IOT control services that executed automatic control of the system,and a framework of smart control system based on context awareness of IoT is proposed. Considering user behavior habits,the concept of user preference is introduced to provide more personalized services. Performance tests of the new context modeling method shows that it has a faster system response time,compared with the control mode of ontology modeling.
