  • Most of access control systems for underground utility tunnel work through wired network between central system and the automatic switch control unit. However, there are several issues regarding the absence of network infrastructure and an outdoor reader in a relatively unique environment. To solve these issues we propose an authenticated key based smart phone control system for secure access to the underground utility tunnel and this scheme is anticipated providing us with crucial information about a systemic entrance history and effective management procedures of utility tunnel. In addition, the proposed scheme enables to access to secured control system in smart phone based bluetooth network and it provides information about systemic control and history management for the switch controls through smart phone applications.

  • From bar code systems and radio frequency identification (RFID) to beacons utilizing low power bluetooth technology, the fusion of information technology and health and medical treatment is spreading through advances such as automated treatment and examination stages and the use of treatment information connected to smart devices. In this paper, designed and implemented a mobile health care system for the safe management of blood transfusions to prevent accidental problems that can occur during patient blood transfusions. It makes safe and effective blood transfusion possible by using smart devices to read information saved on patient bracelets, blood-collecting containers, blood transfusion bags, and medical personnel identification cards so that they match patient information. By applying the blood transfusion management mobile health care system presented and implemented in this paper to blood transfusion processes in hospitals, it was verified that it allows for safe and effective blood transfusion, preventing accidents which may occur in blood transfusion processes.

  • The incident during commuting to school happened frequently in these days, such that the government announced the student commuting safety policy for addressing to implement the safety management system of the unsafer school commuting zone. In this paper, a commuting tracking system is proposed that notifies the location of vehicles and the boarding status of student using BLE beacon and smart phone GPS function. The commuting tracking system that gets the data from the system server of driver's smart phone GPS location and UUID of the beacon which had provided students has configured to provide notifications to parents and related administrators. It provides real-time information about whether a student boarding, boarding times and bus locations for parents and administrators. It verifies the disembarking time for each student and also provides to driver to secure if any student tries to board the wrong school bus and if any students is left behind in the bus.

  • A smart plug is a electronic device which has communication and power control functions for supporting efficient energy usage by saving standby power from outlets. A smart plug can measure amount of consumed electricity of a connected appliance and monitor the usage pattern of electricity by communication with a Energy Management System(EMS) and a smart phone. In addition, a user can control turn on or off of devices remotely by performing a smart application installed in the connected smart phone. In these days, several commercial smart plug products are announced to public. However, they have a weakness in term of cost and convenience. In this paper, we propose a new smart plug with distance-based automatic on/off control functionality to support convenient use of smart plugs by removing The proposed smart plug system does not need a server for controlling each smart plug and communicates among a smart plug, remote controller, and mobile device for sending and receiving power and control data.

  • In recent years, among the IoT products that are used in various ways in everyday life, motorized products are increasing. This study aims to develop a microcontroller unit that can easily control multiple motors and develop an application that makes use of this microcontroller unit. The basis of the hardware developed by the research was the Arduino board, and to it, the Bluetooth module, Zigbee module, and a motor driver were connected. To control the device, an application was designed. The final microcontroller unit and its application may be applied to electric curtains, electric blinds, robots, and other various IoT products. Further research will lead to hardware development that can control various types of motors other than stepping motors.

  • Providing the appropriate feedback from coach to beginner is very important in sports learning. However, it is difficult to receive teaching from coach with no restrictions on time and place for ordinary learners as a hobbyist. This paper aims to describe the development of a smartphone application using internet of things (IoT) devices and data mining techniques in order to overcome the limit of interaction between coaches and learners in real life environments. To accomplish this, we construct the SVM classifier by collecting and extracting feature data directly from coaches and learners, and implement the application using an Android smartphone, Arduino sensor board and Bluetooth module. We are expecting that this proposed application would be help to learn the right beginner's badminton swing movement.

  • In this paper, we have developed an app that can control IPTV - Miracast and the Internet with Android 7.0 on the embedded board. The app can be controlled by the remote control of IPTV and can receive TV when using IPTV. And Miracast and Embedded board are put into the power saving mode. When one mode is selected in this way, the other two modes enter the power saving mode and the power saving control technology is applied to reduce energy consumption. The board used in this paper was Android version 7.1.2 version of Raspberry pie 3B / B + and Asus Tinker board s, and Android Studio program was used to make the app and a synchronization control program was also developed to operate with IPTV remote control. The operation of the Android start program using the power saving power control technology and the remote control synchronization control program developed in this way is confirmed to be normal operation as a result of applying to the actual IPTV.

  • Bicycles are a pollution-free means of transportation. In addition to leisure, the use of bicycles is increasing as alternative eco-friendly transportation. Accordingly, bicycle accidents are also increasing. The purpose of this study is to implement bicycle black box technology to identify situation when a bicycle accident occurs. Currently, bicycle black box products are mainly based on video cameras, and are commercially available by adding various functions mainly on high resolution cameras and are sold at high prices. If a bicycle accident occurs, quantitative data on the accident location at the time of the accident and the state of the bicycle at the time of the accident is required. In this study, IMU sensor used to obtain acceleration and slope, and time and coordinates are obtained. In addition, real-time acceleration and tilt data while is stored in memory card and by using Bluetooth transmit to the smart phone owned by the in real time to prevent accidents and to monitor status.

  • In order to realize IoT(Internet of Things) service, it is necessary to manage sensing data and build a service with respect to its scalability. However, existing internet services use unique protocols and non-standardized functions for each service provider, and it is difficult to provide data management and service because they use short-range communication technology such as Bluetooth. In addition, plurality of APs and gateways must be taken into consideration in establishing a wide area network. In this paper, we propose a sensing data management system using LoRa(Long Range) communication based on Mobius platform. The end device that drives Tas is configured to collect sensing data, configure an application gateway that drives &Cube, and transmit sensing data to the server. In addition, a server that manages the Mobius is configured to handle the sensing data transmitted from the application gateway to provide a monitoring service. We establish a wide area network through LoRa communication between the end device and the gateway and provide data management and service corresponding to the internet through the Mobius platform.
