Recently, Guard lamp was divided from electric facilities for general use as dangerous zone of safety management. This paper presents a remote inspection system of guard lamp that can monitor electrical safety factor. Especially, the developed system adopts the measurement algorithm for detecting resistive leakage current($I_{gr}$) flowing based on the phase difference checkable for sensing at a monitor. Also, It was fabricated the repeater for data transmission and the MMI program At this system, we made experiment on stability of resistive leakage current to verify phase comparison detecting algorism.

A guard lamp system has been installed at the PV positive center, located at Gwangju in Korea. Digital environment that is represented to internet is displacing business way of industry and business achievement way with the fast speed being giving great change on life whole, improve existence business process utilizing internet and Web connection technology, information superhighway to tradition industrialist manufacture and e-transformation's propulsion that wish to maximize productivity and administration efficiency is spread vigorously. In this paper, we wish to accomplish generation equipment's heighten stability and believability through remote monitoring and control of guard lamp system. This paper describes the design of the monitoring system for the sensing data and indirect controlling of the guard lamp system. Most of the conventional monitoring systems depend on the special hardware and software. The essential design of monitoring system is to provide the convenience for the user and the portability for the system. In order for the system to fulfill its requirements, it was designed using Labview GUI facility based on the Windows 2000 environment of IBM PC compatible and Add-oncard based on the TCP/IP protocol. Advantage of the monitoring system are a personnel expenses curtailment effect, of the place restriction and unmanned system of the generationplants, etc..

In this paper, guard lamps at three areas have been investigated to understand the actual conditions of the electric shock hazard of the guard lamps. Upon the basis of the obtained data, the actual conditions of the guard lamps were precisely analyzed in terms of the electric shock hazard. As a result of the investigation, it was turned out that many guard lamps were not installed in organized ways due to the lack of legal regulations, resulting in the increase of electric shock hazard. Therefore, it is necessary, from a point of electric shock protection view, to establish the regulations of equipment installation and management, which can be specifically applied to guard lamps.

This paper describes the checking results and some problems of guard lamps installed in the field. The guard lamp providing night security for people is installed outdoors and exposed to the natural factors causing secular ageing and the people's vandalism, etc., thus it is prone to get troubles in function. In fact, the guard lamps has been left without considering the fundamental measures in the legislative system in spite of the loss of lives due to the electric shock accidents repetitively taking place every year. This study arouses people's attention to the risk due to the lack of management and maintenance of the guard lamp by investigating the recent technology and the actual operating conditions and some problems and countermeasures were ultimately deduced. In this process, we reflected on the various opinions through fieldwork and had a couple of consultations with field staffs, manufacturers concerned and active officers with local autonomous entities.

In this paper, a device for safety inspection of a guard lamp with an automatic switch which has been recently employed in some local autonomous entities was developed. It is technically enhanced by installing a separate inspection box down below, which allows the inspectors can measure the leakage current, the sound function of the electric leakage breaker(ELB), the insulation resistance and the grounding resistance, on the ground. This inspection box makes the inspectors free from the electric shock by being designed to minimize the potential direct contact with the energized terminals. The deliverables of this paper are expected to contribute to carry out the inspection for the guard lamps safely and effectively.

A number of guard lamps are utilized to ensure to safe walking during nighttime. Due to the lack of legal regulations, however, many guard lamps are not installed in organized ways, resulting in the increase of electric shock hazard. In order to establish the legal regulations which can be specifically applied to guard lamps, a research on the actual state of them is performed in this paper. As a result of the research, three regulations are addressed and suggested on equipment installation, management and development.

보안등은 주택가 골목에 안전을 위해 설치하는 중요한 설비로서, 도로 폭이 12m 이하인 장소에 설치된다. 그러내 통행 인구가 없어도 야간시간 내내 점등되고 있기에 낭비되는 전력량이 상당하다. 적외선센서가 부착된 보안등을 교체하게 되면 보행자의 움직임을 통해 일정시간 점등이 되고 이동체가 없을 때는 소등이 되어 전기에너지의 소비를 상당히 줄일 수가 있어 온실가스저감에 기여할 수 있다. 본 논문에서는 적외선센서 보안등의 최적 작동시간을 추적하기 위해 보행자의 통행 분포를 알아보고자 연구지역인 경북대 캠퍼스 내에서 사계절 중 여름철 야간 보행자의 통행패턴을 현장조사하여 분석하였다. 이를 통해 시간별, 공간별 분포 특성을 파악하고 도식화하여 보행자의 통행분포 특성을 파악함으로써 보안등의 작동시간 추적이 가능하였다.
