Design Of Smart Hotel Door Lock System Based On Near Field Communication Technology

Driven by the current development of communication technology,especially the gradual popularization of 5G technology,the Internet of everything in hotels is greatly accelerated,and the demand for intelligent hotels is constantly increasing.However,the current hotel management mode,infrastructure is relatively backward,the degree of intelligence is obviously insufficient.In particular,the hotel room door lock system,still using rf electronic lock,password electronic lock,biometric lock and other ways,there are low security,high development cost,cumbersome use and other shortcomings.Aiming at the above problems,this paper designs an intelligent hotel door lock system based on near field communication technology.Based on the current environment of the hotel industry at home and abroad,this paper proposes an intelligent hotel door lock system based on near field communication technology,aiming to improve the intellectualization of the current intelligent hotel door lock system and facilitate the guests to check in and the administrator to manage.Through literature retrieval,the research status of smart hotel,smart door lock and near field communication technology(NFC)at home and abroad is analyzed.Combined with market research and theoretical analysis,the functional requirements and design indicators of the system are determined,and the overall scheme is designed accordingly.The system is mainly composed of the door lock controller of the room door lock terminal and the room door card management system of the hotel front desk.The door lock controller is designed from hardware,software and antenna.In the microprocessor minimum system,radio frequency communication module,door lock control module,signal indicating module,voltage regulator circuit and other circuits to achieve radio frequency communication,read and write verification,drive door lock,acousto-optic prompt and other functions,to complete the door lock switch control room.In addition,an NFC antenna which can be placed inside the door lock of guest room is designed to improve the efficiency of card reading of the controller.The room door card management system through the property management,room card management,system management,system Settings and other functions,convenient for the hotel administrator of rooms and door card unified management,improve the efficiency of hotel management.By experimental tests show that,this paper designed the intelligent hotel door lock system based on near field communication technology can be done through intelligent device NFC function of door lock switch control,and low power consumption,high safety,use effect is good,the hotel administrator can through the guest room door card system efficient management hotel rooms and door card,the desired design goal.
