Measurement of Outdoor Lighting with a Focus on Watchdog Lighting System in the Area of Electric Station TR Čechy Střcd

摘要

The use of camera and security systems has been becoming a standard part of facilities equipment. Companies protect their property against potential damage and theft and also want to have information about who, when and where was located. These systems are especially used to protect strategic objects whose threat or destruction would have an obvious impact on a society. This group of buildings clearly includes electric stations where the eventual shutdown or destruction would result in a power outage in the regions or a total blackout of the whole country. Therefore, when designing security and camera systems, consideration should be given to all possibilities of space disturbance and to designing the system so that any intruder can be detected in time. In this paper, we will deal in detail with the watchdog lighting system of an electric station that works together with camera systems TSFO. At the very beginning, the right choice of security cameras is essential - they should have a sufficient sensitivity and a resolution to detect objects properly in both day and night hours. The designing of a watchdog lighting system is necessary for the camera system TSFO to work reliably and to provide expected information. The watchdog lighting system is designed with respect to the position and height of the monitoring cameras and by this calculation is set the height of the luminaires, their pitch and the appropriate type and power of the luminaire. At present, most of the lighting systems are provided by LED lights, which, compared to the high-pressure sodium lamps, have many benefits, mainly in the wide range of luminance curve characteristics. The subject of this article is a measuring of watch lighting system in the site of the electric station TR Cechy střed, which uses high-pressure sodium lamps for watchdog lighting system as well as the design of optimization of this lighting system by using LED luminaires capable of distributing the camera lighting component throughout the whole range of the monitored area between the lighting points.
