Research Of Detection Access Control System Based On Bluetooth Low Energy

With the rapid development of mobile Internet technology,intelligent terminals like mobile phones and tablet computers are widely used in access control system.The new type intelligent access control system can overcome the shortcomings of the traditional access control system.For example,the password access control system security is low and easy to be destroyed;The IC card access control system can not recognize people without the IC card;The biometric access control system is expensive and vulnerable to damage,So the new type intelligent access control system has been more and more popular during the developers.At present,the main ways to realize the communication between the intelligent terminal and the access control system are Bluetooth,WIFI,NFC,Zig Bee and so on.BLE(Bluetooth Low Energy)technology has many advantages such as low power consumption,quick connection speed,security,stability and strong practicability(currently intelligent terminal mainstream support BLE),this paper studied the intelligent access control system with BLE as the main means of communication.The main work of this paper is as follows:(1)This paper analyzed the common communication schemes of access control system.The Bluetooth communication protocol and HTTP communication protocol are used to transfer the data generated by the access control system.Then discussed the architecture of Bluetooth and HTTP protocol.(2)This paper analyzed and studied the current market mainstream access control system authentication mechanism,then discussed the applicability of authentication mechanism in BLE access control systemhybrid authentication mechanism.According to the BLE access control system convenient operation and safe use design concept.This paper put forward a way of two key authentication mechanism and a graphical password with the combination of digital password authentication mechanism.(3)According to the functional requirements of BLE access control system,this paper puts forward the overall design scheme of BLE access control system,and develops the access control device based on Arduino hardware platform.Php My Admin is used to design a network database which can be managed by Web interface.Finally,using the Android development technology for the BLE access control system can be installed on the mobile phone intelligent terminal APP.The experimental results show that the BLE access control system has the advantagesof low manufacturing cost and high practicability.
