Research On The Wisdom Campus Oriented Situational Awareness System

With the rapid rising of mobile Internet and development of the mobileintelligent terminal, the way of calculation is becoming more and more diversified.The traditional way of calculation often bind people in front of the computer desk,which makes people only be in a fixed position to operate equipment, so they canonly access limited information and services. But today, we can get all kinds ofinformation and a variety related services through wisdom devices in anytime andanywhere.At the same time, wisdom campus also become a rapid rising area in recentyears. wisdom campus essentially is a concrete application of pervasivecomputing, at present, the wisdom campus’definition is a wisdom and integratedenvironment of working, learning, living based on Internet of Things in campus.It take many application service system as its carrier, to fuse the teaching,studying, administration and living.Among these, wisdom space and situationalawareness techniques play important roles. In recent years, many domestic andforeign experts and scholars have conducted in-depth research on this area.Under this background, this paper firstly expounds the research status at home and abroad of intelligent space situational awareness technology, and analyzes theexisting problems of this field.At the same time, the related threetechnology——smart space, situational awareness and ontology reasoning whichwere involved in this thesis were introduced in detail.And then, this paper mainlystudies the wisdom campus situational awareness system on mobile platform.Firstly analysis all kinds of the situational information in campus, build thecampus situation ontology model. And then, improve the wisdom campussituational aware system frame, analysis and design all modules of this system. Atthe same time, for the problem of precise positioning in campus, design a precisepositioning method which combine GPS and WIFI. Finally, the application ofcollaborative filtering recommendation of optimization technology in wisdomcampus situational awareness system is studied.In this paper, the main work is as follows:(1) The situational information of wisdom campus environment is detailedanalyzed and discussed, and the ontology technology is used to base ontologymodel for wisdom campus scene perception system.(2) The wisdom campus situational awareness system is detailed designed, inwhich, the how to perfect the system architecture, design of each module, and theaccurate position information acquisition and processing, collaborative filteringmethod and other problem are discussed.(3) The wisdom campus situational awareness systems to achieve areimplemented, then, the feasibility and reliability of the design scheme of the system is verified through field experiment, and the experimental results areanalyzed finally.
