Laser infrared light in a forest fire monitoring system (1)

With the continuous development of the cause of afforestation, forest area, forestry volume increase year by year, fire prevention is a priority.

Forest fire is worldwide one of the major disaster, forestry every year a certain number of occur, resulting in significant loss of forest resources and the global environmental pollution. Forest fires have emergency, disaster of randomness, a short time can cause great damage. So if there is fire, it is necessary to adopt very quickly, the fighting is fighting measures, decisions in a timely manner, the important reasons for relevance depends on the discovery of fire behavior, whether timely and accurate analysis, decision-making measures are appropriate. To do this at home and abroad for the prevention, reduction and control of forest fires. In order to realize the standardization of the forest fire prevention, scientific, informational, and implementation of the "prevention, active suppression of policy", really early detection, early settlement. Forest fire monitoring of construction work has become more important.

As a result of forest fire monitoring system for building environmental and construction requirements, making forest fire monitoring system is different from other monitoring systems, forest fire monitoring system should have six characteristics: 1 monitoring range, distance; 2 24 x 7 monitoring; 3 wireless transmission; 4 wind and solar power (rainy day minimum guaranteed 24 hours); 5 lightning earthing safe and reliable; 6 front-end devices work status Center monitoring.

In response to these characteristics, the system selects the device requirements should also be possible to meet these characteristics to meet the appropriate requirements. Laser infrared lamp as a novel infrared light source, reinforcing compared with other light sources, in forest fire monitoring system, with incomparable advantages.

1. laser infrared lamp can be very good to meet system vision wide, accessible, monitoring surface, less established monitoring points, and as far as possible so that each control point monitoring covers the largest area of forest.

Current forest fire monitoring system, basic day monitoring is not a problem but for night surveillance, wide vision, distance is very difficult to overcome obstacles. Night-time monitoring for infrared supplemental lighting equipment required is relatively high, originally traditional infrared light projection distances up to 100 meters, and forest green vegetation on different infrared have greater absorption, making night-time infrared lighting effects. For this, the best solution is to laser infrared lamp. Because laser infrared lamp can at least meet the 100 ~ 500 m distance of the lighting and laser infrared light wavelength single, energy concentrated, makes the green vegetation for the absorption of infrared line affected by 40%, the fully achieve nominal distance lighting.

2. the monitoring point to work 24/7, so the problem must be solved overnight, night-time surveillance monitoring of core is to provide the ability to implement effective distance, effective luminance of the infrared device, with supplemental lighting for infrared-sensitive color go black and white video camera and lens, and night dual-purpose type meet at least 300 meters can see figure; head requires selection of screw outdoor integration head, in order to reduce long-distance image dithering camera installations to ensure the secure and stable.

So on to select the infrared lamp is directly related to the monitoring system of the integrity and relevance.
