一种基于物联网技术的场所感知系统初探

Preliminary Study on a Kind of Place Perception System Based on IOT Technology

近年,随着物联网相关研究工作的深入进行和新业务需求的日益增长,基于物联网技术的各种应用系统不断涌现。通常,人们希望智能物具有环境场所感知能力,因此提出一种基于物联网技术的场所感知应用系统。首先,围绕信息物品维、自主网络维、智能应用维3个维度构建该系统的体系结构,并分析了系统中主要实体间的关系;其次,讨论了体系结构中面向场所感知的专门部件的关键支撑技术及其发展方向,主要涉及环境物位姿传感、场所感知智能应用两个方面,其中,特别地给出一种物联网条件下可行的场所感知算法;最后,通过仿真实验验证了该系统的感知效果。

With advancement of relative research in IOT（internet of things） and increasing requirements for new business,various application systems based on IOT technology emerge continuously.Generally,people hope intelligent things have ability for place perception.Aiming at this requirement,a kind of place perception application system based on IOT technology was proposed in this paper.Firstly,the architecture of the system was constructed from three dimensions which are information things,autonomous networks and intelligent applications,and the relation among main entities in this system was analyzed.Secondly,some key supporting technologies for the place perception oriented components of the architecture and their developments were discussed,and these technologies mainly involve two aspects：object position and orientation sensing and intelligent application for place perception.Among these technologies,a kind of perception algorithm,which is feasible in IOT,was especially proposed.Finally,the effect of the place perception system was verified through simulation.
