Abstract

In this paper, we proposed an electronic attendance-absence recording system using a smartphone that does not require separate BLE(Bluetooth Low Energy) devices and infrastructure by using BLE advertisement technology of smartphone. The existing BLE-based electronic attendance-absence recording system requires a BEL device to be attached to each classroom for services and a separate technology to identify the devices attached to the classroom. Also, due to the interference with each other, sometimes an error occurred in the electronic connection. In this paper, we propose a system to solve the problems about time, place and cost, which is a disadvantage of the conventional Bluetooth beacon system. BLE advertising function of the smartphone that the user is using without BLE device, it is possible to construct infrastructure for electronic attendance-absence recording system. In order to evaluate the effectiveness of the proposed system, we designed the system structure and operation flow and constructed the system using the smart phone in actual used.

본 논문에서는 스마트폰의 BLE 광고 기술을 이용하여 별도의 BLE 디바이스 및 인프라 구축이 필요 없는 스마트폰을 이용한 전자출결시스템을 제안하였다. 기존의 BLE를 이용한 전자출결시스템은 서비스를 위해서는 BEL 디바이스를 각 강의실마다 부착해야 하며 강의실에 부착된 디바이스를 구분하기 위해서는 별도의 기술이 필요하였다. 또한 항시 동작하기 때문에 서로의 간섭으로 인하여 전자출결이 간혹 오류가 생기기도 하였다. 본 논문에서 제안한 전자출결시스템은 기존의 블루투스 비콘 방식의 전자출결시스템의 단점인 시스템 구축을 위한 비용적인 문제를 해결하고, 이동식 전자출결로서 활용이 가능하여 시간과 장소의 문제점을 해결할 수 있으며 별도의 BLE 디바이스 없이 본인이 사용 중인 스마트폰의 BLE(Bluetooth Low Energy) 광고 기능을 이용하여 전자출결을 위한 인프라 구축이 가능한 장점이 있다.
