Based on the rapid development of IT technology and deployment of the Internet through high speed networks, network environments have been changed from office oriented environment based on business industries and public institution even to the interconnection to digital electronics in the home network. Home network based applications are very diverse and the remote monitoring and control areas have been studied. In this paper, we present the design and implementation of a remote real time video monitoring system which provides the moving pictures on the web page through the Internet using JMF. In addition, we present the design and implementation of a remote light control system based on Zigbee.

An internet and network based software and related interface have been developed, which can remotely control and manage an on-site operating system. Developed software modules were composed of two parts: monitoring/management modules and control/diagnosis modules were developed for the network status, warehouse, production and selling status. Modules of control with diagnosis were developed for the on-site operating system and interface. Each module was integrated and the whole modules have been tested with an automatic mushroom grading/sorting system which was built in a laboratory. Developed software modules worked successfully without any uncommon situations such as system down caused by the software or data transfer error. Each software module was developed independently in order to apply easily to other existing on-site systems such as rice processing centers, fruit and vegetable sorting, packaging and distribution centers scattered over the country.

This paper begin a new approach in the water-gate controller using radio communication. The dissertation is on the controllable device development of water-gate in the remote distance from water-gate trough the transceiver by radio communication. The proposed water-gate control device is simple in structure, an suitable for implementation of water-gate control in the remote distance. The remote controller water-gate device inspected the up and down motion of water-gate through the LCD displayer, so that it was very safety driving about the surroundings information, over loading and position of water-gate, and so on.

In this paper, we proposed service security model and remote management service on OSGi computing environment. The model is used to make access control decisions like permission-based security inside the java2 platform. In model, policies are defined using a flat text file and include bundles. It method granted flexibility and extendability of access control of bundles and services. Also, we proposed service architecture efficiently for remote management service.

This research is about the remote control of the infra-ray signal producer and the received signal memory-type control unit. Also by using the infra-ray signal from the remote control, reduction of malfunctions due to infra-ray signal from other devices are presented. Applications on various electric and electronic items to improve the convenience are also shown.

In this paper, we take advantage of the SEN Remote HMI App as a tool based on Raspberry Pi server for the smart home control. This is a smart home control system built in an open and a low-cost Raspberry Pi as a server, and take advantage of Android-based graphical programming software SEN Remote HMI. If you build it based system expansion and additional works interface via the Raspberry Pi and Arduino, it is expected to be extended to the Internet of Things (IoT) enabling environment for the implementation of smart home.

Building energy saving is one of the most important issues in these days. Energy saving control strategies should be developed properly to achieve the saving. One of such area we could apply is the HVAC (Heating, Ventilation and Air-Conditioning) system. Through the optimal control algorithm for building energy management system (EMS), you can not only save the cost of building energy, but also protect HVAC system components against the unexpected condition. In order to verify the effectiveness of building energy saving, field test was accomplished for several months at 'A' building. And to get the measured data, remote control was used. If the remote control is used in BAS (Building Automation System), control and monitoring can be done for all of the building systems, such as HVAC, power, lighting, security and fire-alarm etc. anywhere any time. Using the remote control, Control and monitoring is possible for the testing system without going there. As the results of field test, we could reduce $5{\sim}10\%$ of the building energy cost.

In remote USV (Unmanned Surface Vehicle) maritime operation, the remote operation and control technic and autonomous control technic is required and the emergency mode algorithm is needed certainly for sailing and accomplishing various surveillance, reconnaissance, and underwater search missions of USV. In this paper, we review the countermeasures in emergency situation of the existing USV system (Barracuda) and propose the emergency mode algorithm considering the operation and control, and autonomous control level for the stable USV operation in case of emergency. We analyzed the autonomous control level in view of the mission complexity and environmental difficulty, and human interface, and verified the performance of the autonomous control level when we apply four emergency mode algorithms. It is expected that more stable and reliable operation and cotrol are possible if the proposed algorithm is applied to the environments requiring the various multi-mission USV sailing and mission achievement.

We have designed an embedded controller for the control of a diesel generator using an embedded system. The generator is monitored and controlled remotely via the internet in real-time. The proposed digital controller is designed to handle precisely the distortions and noises of the signals emanating from the diesel generator, and enables abnormal operation of the diesel generator to be notified to the remote manager using the Short Message Service (SMS) of the Internet, which enables the appropriate personnel to take action by remote control according to the incoming messages.

Recent technological advances in utilization and generalization of Internet have overcome some of the limitations of remote robot control range and real-time monitoring system. However, It needs Embedded system with control protocol or hardware which has avility to port the micro realtime operating system in robot control system communicate with remote controlled robot, because those system use the wireless LAM or Bluetooth as a network media. In this paper, we design and implement the wireless MODEM protocol and install it to the server system. Also, we implement a client system could control the remote robot through the server and we assure that this protocol and client/server system ate suitable for small size remote control system based on Internet.
