Abstract

Nowadays, a lot of researches and development of technologies have been done to implement practical smart home systems. Also, with the spread of smart phones and tablet PCs, products utilizing those devices have been applied in our real life in various way. An access control system using mobile devices is considered as one of the main components for smart home implementation. The smart door lock system consists of the door system that collects user information and controls door locking and unlocking of the door and the Access Authentication Management Server(AAM Server) that authenticates users and records access information. It is performed using LoRa network to communicate between the door system and AAM Server. The Door system uses BLE Beacon and Bluetooth module to collect user information, and Arduino, an open source hardware is used to control locking and unlocking of the door and LoRa modules. The Smart Door Lock system is designed to enable wireless communication even if it is not an Ethernet service area using the LoRa module. Authentication for access is performed by comparing the DB data and the received user's information in the server. Therefore, the user can access the door lock simply by accessing the door with the smart phone, if the user is registered in the server. In addition, the facility can be more effectively managed as the administrator manages visitors through the server.
