Focus on forest fire prevention, alarm bells ringing!
FLIR thermal imaging camera 23/2017
5th A forest fire broke out at the Narjilin field of Chenbar Tiger Flag at about 12:00 on The 17th of March. As of yesterday morning, after 3 days and 3 nights, more than9000 personnel to fight the fire, the entire fire outside the open fire has been completely extinguished, the fire area over 8400 hectares, The National Defense Department also mobilized 12 forest firefighting aircraft to fight the fire. From 17 to 18 May, a total of 34 weather stations in Inner Mongolia broke the mid-May extreme record, mainly in Chifeng City, Xing UNITA, In places such as Siling-Goulmer and Hulunbel,13 weather stations have a maximum temperature of more than 40degrees Celsius.
"Now the outside guard task is heavy, the internal cleaning task is heavy. "National Sen defense refers to Chen Bar Tiger Flag"5 17"Li Shuming, head of the forest grassland fire work group, said. It is understood that in recent days, the local temperature is higher, the wind is larger, the precipitation is less, the high forest fire risk level continues. In addition, the complex terrain and other factors also bring great difficulties to fire fighting work.
From " "fire of the stars" gradually developed into a roaring fire, such examples are not uncommon. " A disaster should bring more enlightenment than the pain. Obviously, fire prevention, such as simple monitoring, simple human defense is far from enough. For security, the application of infrared thermal imaging cameras can quickly and effectively detect these hidden fires, and can accurately determine the location and scope of the fire, through smoke to find the fire point, so that early knowledge, early prevention, early extinguishing. On principle, the temperature distribution of fire site can objectively reflect the process of fire occurrence, development and extinguishing, which is of great significance to fire fighting rescue and fire accident investigation. However, due to the lack of technical means, it is not possible to obtain effective lying the temperature distribution data of the fire site, which makes this field is still blank. With the maturity of infrared thermal imager technology, it is possible to obtain temperature distribution data at the fire site, and it is also possible to use fire field temperature to assist fire rescue and determine the cause of fire. The most important thing to remind everyone is that the sentence "prevention is better than disaster relief"! Forest fire, alarm bells ring!
Analysis of the status quo
At present, China's forest fire risk monitoring and early warning methods are mainly satellite forest fire monitoring, artificial monitoring, remote forest fire video monitoring, forest fire intelligent remote monitoring four ways. What is widely used in Our country is the form of artificial monitoring
At present, the comprehensive forest fire prevention capability monitoring system based on infrared thermal imager and visible light dual-vision detection and network transmission has been gradually applied to the field of forest fire protection monitoring. As the front end of the fire protection system, the infrared thermal image embodies a unique range of unmatched features such as ultra-far,sefrom, high accuracy, two-way information transmission, ultra-low light, haze, night monitoring, and rapid and accurate detection of problems.
Referring to infrared thermal imaging, no one does not want to the leader of thermal imaging technology FLIRGroup, the world's largest and most professional thermal imaging technology systems group, with the most comprehensive infrared, wireless, nuclear radiation detection system, master the core: infrared detectors, infrared lenses, infrared systems, The most comprehensive infrared product line.
Today's recommended KATA system is integrated by FLIR infrared thermal imaging equipment to monitor the temperature of objects in the field of view in real time, long-range full-spectral video solution, the system uses advanced , FLIR The passive infrared detection infrared radiation energy technology, whether it is dark and white night, or windy snow, heavy rain, fog on the infrared thermal imaging equipment has no impact, as long as the object has infrared thermal radiation energy can be picture imaging, through the cooperation of fog cameras to make every corner of the observation site perfect presentation. Therefore, early warning of forest fire prevention is available. Eliminate the fire in the bud.
Forest fire prevention system composition
Forest fire prevention integrated capability monitoring system consists of command center system, wireless transmission system, infrared thermal imaging, camera and lens system, head control system, power supply system and tower
Multi-angle field angle and high-multiplier lens selection, specific settings for the surrounding environment. The replaceable camera case allows for rapid upgrades between PT Series HD optics to best-in-class picturequality, allowing us to clearly detect and distinguish objects (people or cars, animals, vegetation), and built-in Dual-sensor video interface analysis software perfect combination, compared with ordinary CCTV cameras, infrared cameras can really and video analysis software perfect combination. FLIR visible light and infrared thermal imaging dual sensor interface management software includes advanced video analysis algorithms designed to analyze thermal surveillance recordings. Because infrared cameras produce thermal images based on the infrared radiation emitted by the scene, they can provide high-contrast thermal images under a variety of conditions. Regardless of weather and lighting conditions, thermal images clearly show the invading targets with high-contrast thermal images, which gives security systems greater consistency in detection performance. With the dual sensor user interface, you can create custom tripwires, isolation zones, temperature alarms, and directional alarm rules. Once the sensor management software detects a high temperature, an alarm is triggered.
Forest fire monitoring system construction environment is very special, so PT-HD The system has the following functions:
The system has six characteristics, all adapted to forest fire prevention.
1st , the monitoring range is large, the distance is far;
2 , round-the-clock monitoring;
3rd , wireless transmission;
4 , scenery complementary power supply ( 24 hours on rainy ) The ;
5th , lightning protection ground is safe and reliable;
6th , front-end equipment working status center monitoring.
7. High sensitivity temperature alarm function.
Effect picture
Next from the fire investigation, auxiliary fire extinguishing, safety hazard detection, search for the cause of the fire, determine the location of the fire, as well as clean up the scene of the fire these aspects one by one introduction PT-HD Practical application of thermal imaging.
Fire Investigation
-HD Fire reconnaissance is the fire force obtained all the information about the object of fire fighting, is the commander deployment mission, the basis of the combat, is the most important work of the whole fire field. Without the data and information provided by fire reconnaissance, other fire fighting and rescue battles lost their way. But in the course of our actual combat, fire reconnaissance is often just a simple ask, look, see the fire, headless fly situation occasionally appears, even by virtue of the simple eye to see, resulting in greater damage also occur. Infrared cameras can be used as an auxiliary tool for fire detection to determine the center position, combustion and spread of the flame. On-site soldiers can observe the fire through the thermal imaging camera, according to the information obtained, the fire field commander can correctly lay out the strength, effectively extinguish the fire.
Clean up the fire. In the latter stages of the fire, in the face of rising water vapor and smoke, it is difficult for firefighters to determine where they really did not put out, spending a lot of time in carpet cooling, but not enough water and time for the smouldering areas that really need to be cooled, often causing firefighters to struggle. Using a thermal imaging camera can help firefighters determine where they really need to cool, which can be very helpful in reducing the time to fight. In fire rescue, thermal imaging cameras are used to determine the center of the fire, the extent of combustion and the spread. Through the thermal imaging camera to observe the fire, the fire combustion and spread, determine the center of the fire. According to the information obtained, the fire commander can correctly lay out the force, effectively extinguishthe fire. In addition, in the fire, the water belt due to the flow of cold water, in the thermal imaging image can be easily observed, even in the smoke of the fire is very obvious, can help firefighters in special circumstances to quickly escape, to prevent disorientation in the fire. Infrared cameras can also help firefighters eliminate hidden sources of fire in complex fire slots. At the scene of a fire, heat is often transmitted to other parts of the site through metal pipes or other metal objects, causing other flammable materials to catch fire and expand the fire. In the smoke-filled, poor line of sight, it is difficult for firefighters to distinguish between high-temperature objects (e.g. metal objects, pipes, etc.) with the naked eye. And with infrared camera, you can clearly detect high temperature objects and take timely cooling rescue measures, or quickly transfer, remove surrounding flammable materials
Infrared cameras not only have irreplaceable advantages in fire protection work, but also have a very broad application prospect in the forest fire prevention industry. In the future, with the popularity of infrared cameras and people's recognition of infrared cameras, I believe that its application value in fire prevention work will continue to be reflected, can greatly protect people's lives and property.
