摘　　要：为了提高物联网设备的互联性及数据处理效率,以智能家居领域为例,设计并实现一种通用的数据服务中间件。通过引入虚拟实体和协议适配器,该中间件可以适配物联网环境中常用设备通信协议,并支持新协议的动态注册。对物联网环境感知数据进行数据建模,以消除数据格式的异构性。通过配置数据处理规则,对物理空间中不同指标对应的数据实现相应的异常值监测。基于混合粒子群算法在保证数据信息完整性的同时达到最大的数据压缩率。采用策略设计模式,通过组合基础的数据服务机制,为上层应用程序提供灵活的数据服务及统一的服务调用接口。To improve the communication and data processing efficiency of IoT devices,I design and implement a general data service middleware in the smart home field.By introducing virtual entities and protocol adapters,the middleware could adapt to the common communication protocols of IoT devices,and new protocol could be dynamically registered.The IoT environment-aware data was modelled to eliminate the heterogeneity of the data format.By configuring data processing rules,the corresponding abnormal values could be monitored for data corresponding to different indicators in the physical space.Based on the hybrid particle swarm algorithm,I ensured the information integrity for data and maximized its compression rate.I adopted the strategy design pattern to provide flexible data service and unified service interfaces for upper-layer applications by combining basic data service mechanisms.
