The Development And Design Of Smart Phone Hotel Access Control System Based On Encrypted QR Code

Hotel access control system is the basic information management system of the current hotel management configuration.At present, the control structure of the hotel access control system mainly adpots a prop for a four, connected with the main control system by wired media,which exists problems such as wiring complexity, poor scalability, repair and maintenance difficulties. On the other hand, the user uses magnetic media or IC card to access control identification,prone to demagnetization or forget problems with a card, causing customers the inconvenience and in trouble. In recent years, as wireless LAN technology and the popularity of smart phones are applied,it is possible for two-dimensional code recognition and WI-FI wireless network access management to achieve the hotel access control system. This paper presents a smart phone hotel access control management system based on encrypted two-dimensional code and WI-FI wireless network communications, where smart phone is mobile Internet terminal,and encrypted two-dimensional code as an electronic key,Through the embedded access controller to achieve two-dimensional code scanning and identification,to complete the management of the hotel access control.The implement of the system can greatly improve the ability of hotel management and convenience of the user.The main work in the paper are as follows:1.Based on the analysis of current hotel access control management,the business process model of hotel access control management is proposed.Based on this model, smart phone access control system model is designed and control principle is planed based on two-dimensional code encryption and WI-FI technology.2.The embedded controller is developed with Cortex A9 embedded development board,based on wireless LAN communications. By USB camera scanning interface design,the acquisition, recognition and decoding of the encrypted two-dimensional code image of the phone in user is achieved.By WI-FI communication interface design, to achieve the hotel room door status isinformed by wireless network.3.Based on object-oriented analysis and design techniques,in the J2 EE development environment and MySQL database management platform, this paper develops hotel access control system on the server side to realize the management of guests check,hotel rooms and guests departure.And then tests the system management function.4.Adopting mobile Internet technology,this paper designs smart phone client terminal APP based on Android system.,customers can use this APP to login system, generate electronic key-dimensional code image and encrypt it,which realizes the time limit management and identification of encrypted QR Code.
