Abstract：Internet of Things applications in public safety managementa survey Purpose Public safety issues are highly concerned by the state and publicAs an emerging network technology and industrial modeInternet of ThingsIoThas great application prospect because of its architecture advantages and technical featuresand has drawn wide attention from all walks of lifeWith the development of IoTespecially the putting forward of concept of public safety IoTIoT has been a certain degree of application in the field of public safetyBecause of thatpublic safety regulatory technology is improvedThe paper aims to discuss this issueDesignmethodologyapproach By summarizing scholarsresearch resultsthis paper analyzes the application of IoT in public safety regulationpoints out the challenges in applicationand then puts forward some suggestionspointing out IoT development prospects in the area of public safety regulationFindings The application of IoT in the field of public safety from the perspective of IoT architecture and the perspective of the main technologies of IoT is paid attentionAnd this market that IoT added to other services in the public sector would generate46 trillion of net profit globally in the next decadeThereforegovernment leaders and public safety organizations should start exploring the full potential that IoT could offer to public safetyOriginalityvalue The research will develop the theory of IOTwhich is valuable to strengthen the IOT technology innovation and the application extensionThe application of IOT in public safety will enhance the ability to supervise the public safety and guarantee the safe social condition for peoples lifeSo it is valuable in theory and in practiceLibrary AutomationIoT can be used to automatically control facilities and resources in the librarysuch as automatic adjustment of lightingtemperature and humidityRetrieval and IndexingAlthough the article does not clearly mention itIoT can be combined with other systemssuch as automatic book search systemsInstificational CollectionThrough IoTyou can better monitor the library collection to ensure that it is preserved in a suitable environmentHow IoT is applied to public libraries to improve its servicesThe IOT applications here include the use of smart sensor networks to monitor the environmental factorssuch as lighttemperatureand humidityof the librarycontrol energy consumptionensure a clean and comfortable learning environmentand eliminate potential security risksIn additionthese technologies can also help existing libraries become modern smart libraries
