Recently, a re-painting robot was developed to semi-automatically conduct blasting work in bridge spaces to improve work productivity and worker safety. In this study, a vision sensor-based monitoring module was developed to automatically move the re-painting robot along the path. The monitoring module provides direction information to the robot by analyzing the boundary between the painting surface and the metal surface. To stably measure images in unstable environments, various techniques for improving image visibility were applied in this study. Then, the driving performance was verified in a similar environment.

This study is concerned with the design of the communication based evaluation simulator for the development of the operational control algorithm for PRT(Personal Rapid Transit) system which has very short headway and requires accurate speed control of the vehicles to avoid the impact between the vehicles. The evaluation simulator is composed of central control system, vehicle control system, communication control system, AP for wireless communication, and monitoring system. For the mobile characteristics of the PRT vehicles wireless communication is employed for the transmission of the control and status information between the central control system and the vehicle control system. By using simple test operational control algorithm the effectiveness of the proposed evaluation simulator is shown.

The home network is the technique to guarantee a safe, economical, socially integrated, and healthy life to the family and it provides domestic safety, instrument control, controllable energy and health monitoring by the connection of the home appliances using wired and wireless networks. A home control system has been developed for managing and controlling home appliances. This paper designs the broadband PLC home controller using broadband PLC technology which can save much cost at a network infrastructure using the existing power line at a home and design the USB home controller using USB technology which is low cost and has many goods with it. And the embedded home server manages those. The CDMA module provides mobile functions to the home control system in this paper. And we choose the OSGi specification which is compatible with other home middleware and can accept various communication techniques of home network

Despite the government's various safety measures, the number of safety accidents continues to rise and the interior is more likely to occur indoors than outdoors. Safety accidents involving young children account for more than 70 % of the safety accidents in the safety accidents, and the ratio of safety accidents in the classroom or classroom is more than 50 %. In this thesis the author proposes the system managing the accidents notification service using LED lighting and access entry control. Utilizing IoT technology, remote control or access can be controlled remotely by controlling multiple lights and entrances from each room and by means of a number of lighting and entrances. By monitoring and analyzing real-time status via server PC and mobile interface, it can control the maximum control and incident prevention, automatic control, and automatic control.

The process of automation and monitoring in industrial control system involves the use of many types of sensors. A programmable logic controller plays an important role in the automation of the different processes in the power plant system. The major control units are boiler for temperature and pressure, turbine for speed of motor, generator for voltage, conveyer belt for fuel. The power plant units are controlled using microcontrollers and PLCs, but FPGA can be the feasible solution. The paper focused on the design and simulation of hardware chip to monitor boiler, turbine, generator and conveyer belt. The hardware chip of the plant is designed in Xilinx Vivado Simulator 17.4 software using VHDL programming. The methodology includes VHDL code design, simulation, verification and testing on Virtex-5 FPGA hardware. The system has four independent buzzers used to indicate the status of the boiler, generator, turbine motor and conveyer belt in on/off conditions respectively. The GSM is used to display corresponding message on the mobile to know the status of the device in on/off condition. The system is very much helpful for the industries working on plant automation with FPGA hardware integration.

이 논문에서는 소포 배달 서비스를 위한 인텔리전트 모니터링 시스템(Intelligent Monitoring and Control System; IMCS)에 대해 기술한다. IMCS 는 GIS, GPS 그리고 무선 통신 기술을 이용하여 택배의 접수와 배달 업무를 효율적이고 효과적으로 개발하기 위한 시스템이다. IMCS는 모두 세개의 서브 시스템으로 구성되어 있는데 접수와 배달 계획을 수립하는 PDPS(Pick-up and Delivery Planning System)과 접수/배달 현황과 차량의 위치를 파악할 수 있는 PDMS(Pick-up and Delivery Monitoring System), 그리고 개인휴대단말기(PDA)을 이용한 실시간 업무 처리 시스템인 MOCS(Mobile Operations and Communication System)으로 구성되어 있다. PDPS는 GIS와 최적화 알고리즘을 이용하여 접수와 배달을 위한 방문 순서와 경로 그리고 고객에게 방문할 예정시간 등을 생성한다. MOCS에서는 GPS와 무선 통신을 이용하여 업무 중 발생한 접수/배달 결과와 위치 정보를 실시간으로 PDMS에 전송하고 바코드 스캐닝과 전자 서명 등의 업무를 지원한다. PDMS에서는 수신한 정보에 따라 소포의 접수/배달 현황과 차량의 위치를 전자지도 상에 표현하고 업무 차량의 이동 궤적을 표시하여 계획된 경로와 비교하여 모니터링하고 관제할 수 있다. 현재 IMCS는 국내 한 우체국에서 시범 운영되고 있다.

This paper suggests one model, which can be monitor and control target system at anytime and anywhere by a WAP and ME based personal cellular phone(Feature phone) and internet connection. The suggesting model tried to overcome constraints of distance and mobility of conventional methods, TCP/IP based remote data monitoring system, which combine PDA and WLAN technologies. For the experiments of suggesting model, the target systems are constructed with individual modules, which need AC or DC power control. The development software for the control and monitor of local system use NI Labview for the easy-programming and confidence. Also, web server use APM setup for the general user. The mobile connection environments of personal cellular phone are programmed by use WML and mHTML language for the general access. Through the experiments, we have showed that suggesting model can overcome constraints of distance and mobility of conventional system.

Recently, video surveillance is becoming more and more common as many camera are installed due to crime, terrorism, traffic and security. And systems that control cameras are becoming increasingly general. Video input from the installed camera is monitored by the multiscreen at the central control center, it is essential to simultaneously monitor multiscreen in real-time to quickly respond to situations or dangers. However, monitoring of multiscreen in a mobile environment such as a smart phone is not applied to hardware specifications or network bandwidth problems. For resolving these problems, in this paper, we propose a system that can monitor multiscreen in real-time in mobile-phone environment. We reconstruct the desired multiscreen through transcoding, it is possible to monitor continuously video streaming of multiple cameras, and to have the advantage of being mobile in mobile-phone environment.
