본 연구의 목적은 SCADA 시스템을 이용하여 전력, 발전설비, 송유시설, 가스처리, 도로교통, 폐수처리 등 사회인프라 구조물에 대한 능동적 재난관리 및 방지 방법론을 개발하는 것이다. SCADA 시스템은 원격으로 제어기능을 수행하고, 운영 성능 분석 및 보고하기 위한 컴퓨팅 시스템이다. 여러 제작사의 이기종 설비 시스템들을 단일 SCADA 시스템에서 관리하기 위해서는 이기종간의 데이터 호환과 정보 수집의 일반화가 필요하며, 본 연구에서는 이를 XML 기반의 데이터 통신을 통해 해결하고자 하였다. 본 연구에서는 해상풍력발전 설비의 이기종간 데이터 일반화를 목표로 하였고, 나아가 발전 설비 외에도 이기종 단말의 데이터 동기화가 필요한 경우에 XML을 이용한 이기종 단말의 데이터 수집 방법론을 활용할 수 있을 것이다.

In this paper, we present the architecture design of CDMA/TDMA modem chipset for wireless telemetry system. The wireless telemetry system a measuring data collecting system from many RTs(Remote Terminal) installed at the specific area using wireless communication technology. It consists of CU single CU (Central Unit) for collecting data and a large amount of RTs for transmitting the measuring data. We propose the hardware architecture of the modem for RT and CU. We also design those modem using Verilog HDL and synthesis them using Synopsys$^{TM}$ CAD tool. The modem of RT is implemented with 27K gates and that of CU is implemented around 220k gates using 0.6${\mu}{\textrm}{m}$ CMOS standard cell. The proposed system is implemented and tested using Altera$^{TM}$ FPGA.PGA.

Recently, as interest in health increases, the wearable market that can collect various biometric information is expanding. In addition, telemedicine and healthcare services through these bio-signals are expected to become common. In this paper, we introduce a service that can store bio-signals collected through IoT equipment in a database and monitor them in real time through the web. By implementing a system for collecting and storing biometric data and real-time monitoring, it can be utilized for various health management diagnosis.

Currently, usability tests for web sites with representative users are conducted in laboratory environment that disturbs subjects' natural behavior. These test methods are inefficient for tests that require large number of subjects, because experimenters and subjects should be located in the same place at the same time during the test. In this study, a remote usability test tool, called 'RIO' has been developed to cope with these laboratory-based experiment problems - the 'synchronism' and the 'unnatural environment'. The tool is separated into three parts: 'Project Manager', 'Remote Interaction Observer', and 'Interaction Analyzer'. 'Project Manager' sets up overall experimental parameters and actual tasks to be peformed by subjects. 'Remote Interaction Observer', endued with Microsoft Internet Explorer Control, is a modified Web Browser which records user interactions, screen images and elaborate browser events while subject performs given tasks. This module is distributed to subjects as an installable software package. When they finish all the tasks, the captured interaction data is compressed and sent to 'Interaction Data Server' automatically. 'Interaction Analyzer' visualizes interaction data from the 'Interaction Data Server'. It also generates project-scope statistics which facilitate discovering peculiar cases among interaction submissions.

In this paper, I describe a system for remote monitoring of devices Android-based sensor data recorded during the operation of the ballast water treatment system. The proposed remote monitoring system is Designed and implemented when a problem occurs in the ballast water treatment system installed in the vessel, provide information if you are unable to determine the cause in the field or engineer dispatch request of external. System developed is composed of a server holding the sensor data information collected from the vessel and a mobile device that is not bound to time and place. The transmission of sensor data between mobile devices and server, and is implemented by TCP/IP to transmit information securely. System is composed of request to the server from the mobile device after the user inputs the input values, to transmit the sensor data. The device provides the information of the sensor with a high level of importance to the user. Through the remote monitoring sensor information of the ballast water treatment system, the system is made to predict the failure of the sensor.

In this paper, we propose a real-time remote monitoring system for distributed solar power generation system. The proposed system consists of PVC, UTC, OTC and monitoring server. PVC collects the operational information from the PV's inverter via serial interface. The sensing data is transmitted to the server by wireless communications and stored in the DB server. The PV's status is monitored via UTC, and the operating of PVC and UTC are managed by OTC. In addition, by providing information about the power generated by PV system and failure diagnosis in real time, the proposed system shows the possibility of reducing the maintenance costs and improved failure recovery time.
