What is the purpose of using a thermal imager in a forest fire prevention system?

Infrared thermal imaging technology is one of the key technologies in forest fire prevention, which can carry out all-weather, long-distance and wide-range real-time monitoring, and timely discover potential fire hazards by analyzing temperature changes, so as to provide fast and effective guidance for fire extinguishing actions. Compared with traditional smoke detectors, thermal imagers can be used in fire prevention to achieve early warning, and high temperature alarms can be found in the heat accumulation stage before the first stage, so as to truly prevent "unburned".

Through the Gewu Youxin infrared thermal imaging forest fire prevention image monitoring system, the staff can conduct 24-hour real-time dynamic monitoring of the forest area with a radius of 1 km around the monitoring point in the monitoring center, which can detect the fire at the first time, find the disaster or hidden danger as soon as possible, deal with the possible sudden fire and other abnormal events in a timely manner, and provide a basis for on-site command when the disaster occurs.

When a fire breaks out, especially in the case of a forest fire, the smoke produced by the flames is very large, often obscuring the real ignition point, as well as the tendency of the fire to spread. Thermal imaging cameras have a strong ability to penetrate smoke, which can effectively find the real ignition point, as well as the spread trend of fire, therefore, it can be used to direct firefighting and minimize economic and human losses.

Forest fires, on the other hand, often have underground fires when ground fires are extinguished, so there is often a resurgence of fires. Thermal imaging cameras can detect anomalies in the surface temperature of the forest after the fire, and determine the possible location of underground fires by monitoring the temperature of the forest surface after the fire.

Infrared thermal imaging technology is not affected by light, can achieve all-weather monitoring, and has the ability to penetrate smoke and overcome rain and fog, which helps to detect disasters or hidden dangers in advance, quickly locate the real fire point and fire spread trend, and reduce the harm caused by forest fires.

Just like surveillance, call the police when you find the monitoring target or there is a fire, and put out the fire in time to avoid forest fires.

Dear, I am glad to answer Yu Dan for you: What are the core functions of thermal imaging indoor fire protection equipmentAnswer: The core functions of thermal imaging indoor fire protection equipment include smoking detection, temperature anomaly detection, fire point detection and intrusion detection, four core functions, automatic pyrotechnic recognition intelligent image processor can use pyrotechnic recognition algorithm to automatically detect the fire in the monitoring area, find open flames and hidden flames at the first time, and transmit the results of the inspection through the network transmission system Thermal imaging is a kind of "infrared thermal imaging" The amazing technology that converts thermal radiation images into visible images allows people to see things they couldn't see before.

The device that achieves this dispersion is called a thermal imager.

Because thermal imaging technology has its advantages and characteristics for forest fire prevention:

1.Multi-channel calculation of forest fires, low false alarm rate, low false alarm rate, forest environmental thermal energy detection, forest key area arming, fireworks identification auxiliary detection and other ways to shorten the fire warning time and avoid the spread of fire.

2.Irregular scanning paths can be customized, and various scanning methods such as preset, spiral, apple peeling, and timing watch are supported to shorten the scanning time, improve scanning efficiency, and avoid the spread of fire during the scanning cycle.

3.The multi-path alarm channel can not only communicate through microwave and optical fiber, but also send back alarm information with the help of Beidou satellite or intercom short-wave base station in an emergency to prevent fire leakage.

4.The image clarity is high, the thermal imaging reflection is sensitive, and the square meter @ 1000 meters is repeatedly detected without false alarms, and the response is rapid.

5.It supports horizontal and vertical cross-heat source shielding, supports automatic tracking of high-temperature heat sources, shortens the fire positioning cycle, and realizes early detection and early extinguishment.

Application of infrared thermal imager 1. Target monitoring at night and under harsh climatic conditions At night, the equipment that needs to work with visible light can no longer work normally, and if artificial lighting is used, it is easy to expose the target. If a low-light night vision device is used, it also works in the visible light band and still needs external light for illumination. The infrared thermal imager passively receives the infrared thermal radiation of the target itself, which can work normally day and night, and will not expose itself.

Also in the rain, fog and other harsh climatic conditions, because the wavelength of visible light is short, the ability to overcome obstacles is poor, so the observation effect is poor, but the wavelength of infrared is longer, especially the thermal imager working in 8-14um, the ability to penetrate rain and fog is stronger, so at night and in bad weather conditions, the use of infrared thermal imaging monitoring equipment can still monitor various targets normally. 2. Fire monitoring Because the infrared thermal imager is a device that reflects the surface temperature of the object and imprints, it can be used as an effective fire alarm device in addition to being used as on-site monitoring at night. With the existing ordinary methods, it is difficult to detect such hidden fire signs.

The application of infrared thermal imager can quickly and effectively find these hidden fires, and can accurately determine the location and scope of the fire, find the ignition point through the smoke, so as to know early and prevent and extinguish as soon as possible. 3. Camouflage and identification of concealed targets Camouflage is mainly based on visible light observation, criminals usually hide in the grass and woods when committing crimes, due to the harsh environment in the field and people's visual illusions, it is easy to make wrong judgments. The infrared thermal imager passively accepts the thermal radiation of the target itself, and the temperature and infrared radiation of the human body and the vehicle are generally much greater than the temperature and infrared radiation of the grass and trees, so it is not easy to camouflage, and it is not easy to make wrong judgments.

Digital and networked video recording and remote monitoring technology.

Yes, in many forest fire prevention systems, thermal imaging has been widely used, many high-end fire monitoring plays a very important role in many national geological forests, and the high-end infrared detector chip developed by Arrow Optoelectronics is applied to many high-end fire monitoring.

The causes of fire can be divided into natural factors and man-made factors, natural fires are due to the presence of forest combustibles, fire danger weather and fire sources, which are easy to occur in the dry season; The human factor is often the main factor in the occurrence of fires, an unextinguished cigarette butt, the ashes of rural burning straw, in flammable and dry weather, are very prone to fire.

The thermal imaging camera passively receives the infrared heat radiation of the target itself, so it can work normally day and night. Compared with visible light, the wavelength of infrared rays is longer, especially the thermal imaging working at 8 to 14 m, the ability to overcome rain, snow and fog is higher, and the use of thermal imaging monitoring equipment can reliably monitor and warn various targets at night and under harsh climatic conditions.

Thermal imaging has a strong ability to penetrate smoke and overcome rain and fog, and the forest climate is complex, and the smoke generated by rain fog or flame often covers the initial fire, causing the fire to spread faster. Thermal imaging has the ability to penetrate smoke and overcome rain and fog, effectively identifying the true ignition point and identifying the spread of fire.

At the same time, the thermal imaging camera has strong resistance to concealment and excavates potential hidden dangers, forest fires are often caused by small flames that are not obvious, but it is difficult to detect these hidden fires in time; At the same time, after the fire is extinguished, there may still be hidden underground fires, which can easily cause resurgence.

Jingyang Technology adopts the third-generation focal plane detector technology, independent research and development, independent design, and its own production process, with high temperature sensitivity and reach; 420*315 uncooled focal plane detector is used, with clear image and high resolution; The service life is long, and the equipment can work continuously for a long time.

Thermal imaging can automatically measure the maximum temperature of objects in the field of view in real time, and if the temperature exceeds the alarm temperature rise set by the system, it can automatically alarm and output an alarm signal. As a result, early warning of forest fire prevention can be provided. In large areas of forest, fires are often started by hidden fires that are not obvious.

It is difficult to detect such hidden fire signs with existing traditional ordinary methods. With the use of thermal imaging, these hidden fires can be quickly and effectively detected and extinguished in the first place.

With the development of automobile gasoline engines in the direction of high speed, high compression ratio, high power, low fuel consumption and low emissions, the traditional ignition device has not adapted to the requirements of use. The core components of the ignition device are the ignition coil and the switchgear, and the spark plug can produce a spark with sufficient energy to increase the energy of the ignition coil, which is the basic condition for the ignition device to adapt to the operation of modern engines.

Objects in nature that are higher than absolute zero (-273) are constantly emitting infrared rays. Thermal imaging converts infrared radiation from the surface of an object into a visible image through an optical system, an infrared detector chip and an electronic processing system. To put it simply, the principle of thermal imaging is to use temperature imaging to transform the invisible infrared energy emitted by an object into a visible thermal image.

The different colors on the top of the thermal image represent the different temperatures of the object being measured.

Thermal imaging technology is one of the key technologies in forest fire prevention. Thermal imaging can carry out all-weather, long-distance and wide-range real-time monitoring of forests, and can detect potential fire hazards in time by analyzing temperature changes, providing fast and effective guidance for fire extinguishing actions. Compared with traditional smoke detectors, thermal imaging can achieve early warning, and high temperatures can be found and alarmed in the heat accumulation stage before the first stage, so as to truly realize fire prevention and "unburned".

According to statistics, a large proportion of large-scale forest fires are caused by invisible hidden fires.

With the rapid development of security technology, thermal imaging technology has been pushed to the historical stage of forest fire prevention, the principle of thermal imaging technology is any object, as long as its temperature is higher than the absolute temperature zero degree (degree).

Although all objects do not emit light, they will radiate infrared, (infrared is also known as thermal radiation), the infrared rays radiated by objects of different temperatures are absorbed by the infrared thermal detector in the thermal imaging camera, resulting in temperature changes, thereby producing electrical effects, and the electrical signal is then amplified and processed to obtain a thermal image corresponding to the thermal distribution on the surface of the object, which is what we all call "infrared thermal imaging".

Once there is a hidden fire, the temperature is different from the surrounding environment, and it will be discovered, so it is already a trend for forest fire prevention to be monitored by thermal imaging cameras, which can be detected and prevented as early as possible.

A friend of mine who does forest fire prevention projects in Shandong Province has used the thermal imaging camera of Shenzhen Jingyang Technology, and he told me that the overall effect is not bad, you can consult with their business personnel, or go to their official website to understand.
