The related industrial technologies are also being developed in medicine, education, the military, transportation, process management, security management and information technology industries due to a rapid progress in telecommunications technology. The supervisory remote control system is based upon telecommunications technology. The supervisory remote control systems are used in various ways such as city gas, water supply and drainage, environment, power, communication and device control fields. The supervisory remort control system became a solution with complex systems and important technologies in electricity, city gas filed that require safety management skills. The supervisory remote control system as a special technology has a lot of practical applications. In this paper, Let me examine the present status of remort control system applications and present development plans and alternatives in city-gas industrial technology.

For the purpose of reducing the energy consumption in the house heating, the various devices have been developed. One of these is to control the flow in the heat pipe and the flow control valve using shape memory alloy(SMA) spring is proposed in our study. The proposed house heating system is to save the gas consumption and the remote control system is designed for the convenience of using the proposed valve. The developed valve consists of SMA spring, disk, return spring, and regulation handle. The regulation handle is for supplying the additional hot water and is controlled by remote-control-motor. In order to design the remote control system, the Zigbee wireless communication protocol is used. The performance of the proposed valve structure is shown through the experimental result.

It is possible to make a practical application for many services by using Home Networking. It's brings much improve the quality of our life. Remote control communication should be made by Home Network but present networks are generally using wireless Internet. But, this method don't use exist home and not install wireless internet. Because It need to many devices. Therefore, in this paper we implement gas valve remote control system using RPM(Radio Packet Modem). We can easily installing systems and operating. This system provide different solution for Home networking.

The Measurement of risk parameter in city-gas equipments have been measured and confirmed by human, and evolved into remote monitoring system using wireless communication. Furthermore, domestic and international industry increase the efficiency of management, which can develop remote monitoring and control system using wireless communication. However, Those wireless system might be decrease the efficiency and ease because of connecting PDA and lap-top using wire-cable when data have checked immediately from outside. This paper is able to improve efficiency of safety management on city-gas equipments by developing mobile city-gas safety management system on AR.

Smart Home or Home Network technology is one that continuously creates added value, making a better life. This paper designed and developed a smart home control system using smart phone. This proposed smart home system consists of home server control system, remote smart application system and home node structure. Home node structure, in detail, is composed of intrusion detection, gas leakage or gas valve control, door lock, automatic curtain, ventilation control and On/Off control modules and these modules are controlled at home server. Home server makes it easy to control home automatic control system anytime, anywhere as it provides remote interface that enables control via smartphone and user interface in itself.

In present, most of metallic structures (gas pipeline, oil pipeline, water pipeline, etc) are running parallel with subway in Seoul and Pusan.In this case, subway system make a stray current due to electrical corrosion on metallic structures. The owner of metallic structures has a burden of responsibility for the protection of corrosion and the prevention against big accident such as gas explosion or soil pollution and so on. So, they have to measure and analyze the data about P/S(Pipe to Soil) potential, amplitude of stray current, point of source of stray current and so on. In this paper, results of development about Wireless Remote Monitoring and Control System on Underground Pipeline in Stray Current Conditions are presented. And also field test data should be reporting.
