Design And Implementation Of Access Control System For Smart Community

With the acceleration of the process of urbanization,the smart city as a new concept of sustainable development that have swept across the globe,Smart community as an important part of the smart city,its construction has become a hot project in the last one hundred meters of smart city construction.Intelligent access control system as the first barrier of safe life in smart community,at the present stage,which generally have issues such as low security,poor maintenance,networking difficulties and low integration,which unable to meet the needs of smart residential district to provide higher quality services.Through research of service system and technology system of smart Community,the thesis developed an intellegent access control system for the scene of smart residential district in the future with the design philosophy of "Internet plus access control",according to the characteristics of the smart residential district.The main researches of this paper are as follows:1.Through research of service system and technology system of smart Community,the mainstream technologies in smart community technology system such as BLE,mobile Internet technology and cloud service technology are introduced into the design of smart community access control system.2.The design of IoT-based access control system was divided into: hardware design of access control,application design of mobile terminal and the design of server management system.In terms of hardware design,bluetooth control and RF transceiver module are designed Based on the CC2540 chip of TI Ltd.In terms of software design,intelligent door application is designed based on iOS platform,meanwhile,it can realize remote video monitoring and remote push function of property information.Server is designed based cloud services,mainly to achieve storage,analysis and distribution functions of access control configuration information,user information and other data.3.The parameters of RSSI-based ranging were optimized with the method of linear regression based on least square method and Gauss filter algorithm,and multi-point smoothing optimization algorithm,which improved the sensitivity of automatic door opening,then the performance and function of the access control system were tested.The test results show that the smart community access control system can effectively improve the security,convenience and integration,and convenient for networking and maintenance.The thesis combines the characteristics of service system and technology system of smart community,and then developed an intellegent access control system to meet the needs of smart community,which provides a new way for the development of access control system in the future.
