Abstract：Internet of Things-based intelligent evacuation protocol in libraries Purpose The purpose of this paper is to propose a theoretical framework of applying the Internet of ThingsIoTtechnologies to the intelligent evacuation protocol in libraries at emergency situationsDesignmethodologyapproach The authors conducted field investigations on eight libraries in WuhanChinaanalyzed the characteristics of crowd gathering in libraries and the problems of the librariesexisting evacuation plansThereforean IoT-based intelligent evacuation protocol in libraries was proposedIts basic structure consisted of five componentsthe information basethe protocol basethe IoT sensorsthe information fusion system and the intelligent evacuation protocol generation systemIn the information fusion systemDempsterShaferD-Sevidence theory was employed as the information fusion algorithm to fuse the multi-sensor information at multiple time pointsso as to reduce the uncertainty of disaster predictionThe authors also conducted a case study on the Library L in WuhanChinaA specific evacuation route was generated for a fire and the crowd evacuation was simulated by the software PatherfindFindings The proposed IoT-based evacuation protocol has four distinguishing featuresscenario correspondingprecise evacuationdynamic correction and intelligent decision-makingThe case study shows that the proposed protocol is feasible in practiceindicating that the IoT technologies have great potential to be successfully applied to the safety management in librariesResearch limitationsimplications The software and hardware requirements as well as the Internet network requirements of IoT technologies need to be further discussedPractical implications The proposed IoT-based intelligent evacuation protocol can be widely used in librarieswhich is one of the inspirations for the use of IoT technologies in modern constructersOriginalityvalue The application of IoT technologies in libraries is a brand-new topic that has drawn much attention in academia recentlyThe crowd safety management in libraries is of great significanceand there is little professional literature on itThis paper proposes an IoT-based intelligent evacuation protocolaiming at improving the safety management in libraries at emergency situationsLibrary AutomationThe smart evacuation agreement uses IoT technology to automatically generate evacuation pathsInstificational CollectionIt may involve the specific layout and characteristics of library buildings and venuesbut more information requires more information to determineThis article mainly discusses how to apply the Internet of ThingsIoTtechnology in the librarys smart evacuation agreementUsing IoT technologythe information collected by multi-sensor at multiple time points is used to reduce the uncertainty of disaster prediction as an information fusion algorithm theory as information fusion algorithm
