基于情境感知技术的智慧城市服务系统研究

A study on the smart city server system based on context-aware technology

随着城市规模越来越复杂,全国各级政府都在进行城市物联网和信息化建设,目前虽然搭建了互联骨干网和部署了大量的传感器,收集了众多的城市行为数据,但落后的信息管理模式难以体现信息价值,将信息体现在服务提升之中,造成信息资源的极大浪费。因此,将情境感知技术引入到智慧城市服务的应用之中,构建了一个基于情境感知的城市服务系统,并通过情境信息采集、情境信息推理和服务配置模型等关键技术,实时感知城市内的情境需求,从而提供智能化的业务服务组合。最后通过一社区智慧街道管理系统来验证本文所设计的系统效果。

As the city scale is becoming bigger and bigger,the governments at all levels are working on city Internet of things（IOT）and information system construction.Although the Internet backbone networks are set up and a large number of sensors are deployed which can collect numerous data on city behaviors,the poor information management mode hinders the realization of the value of information which should be used to promote service,and results in enormous waste.So we introduce the situational awareness technology to smart city services,and build a city service system based on situational awareness.Key techniques such as information collection,context information inference and service configuration model are employed to achieve real-time situation perception of the cities and provide intelligent business service portfolio.Experiments on a community smart management system verify the effect of the system designed in this paper.
