What is the application of thermal imaging technology in the intelligent weak electricity industry?

Technology is constantly improving, technology products are changing with each passing day, and artificial intelligence is being screened in the security industry. At the same time, infrared thermal imaging products are widely used in the civilian field with increasing trend.

What is thermal imaging technology?

In nature, all objects above absolute zero (-273.15 °C) are constantly radiating outwards and the nature of the object itself, temperature-related electromagnetic waves, a phenomenon known as thermal radiation. At different temperatures, the wavelength of the thermal radiation emitted by the object is different.

Thermal imaging technology refers to the use of an infrared detector and an optical imaging objective to receive the infrared radiation energy distribution pattern of the target to be reflected on the photosensitive element of the infrared detector, thereby obtaining an infrared thermal image, which is related to the surface of the object. The heat distribution field corresponds. In general, thermal imaging is the conversion of invisible infrared thermal radiation energy emitted by an object into a visible video image.

Thermal imaging advantages

The first distance that can be "seen" is very far. In the actual test of the camera, we usually touch the fill distance of the infrared light from 50 meters to 100 meters, but the imaging of the thermal imaging camera is not limited by the ambient light. Long focal length thermal imaging cameras can observe people over 3 kilometers and vehicles over 6 kilometers.

Second, the thermal imaging is very concealed. It completely passively receives signals, does not actively transmit detection signals, and is not easily detected by anti-reconnaissance means.

Third, it is not affected by the environment such as rain, snow, fog, and sputum, and has strong penetrating power. The imaging effect under severe weather conditions is almost unaffected. In particular, the long-wave infrared thermal imager that acts on 8-14um has a stronger ability to penetrate fog.

Fourth, you can work around the clock, without interference from glare and low light. Infrared thermal imaging does not require illumination and ambient light, but produces imagery from the target and background radiation, so the infrared thermal imaging system can work 24 hours a day, and is not subject to visible light interference like other night vision devices. . Low-light cameras cannot be imaged without ambient light.

Fifth, it can identify hidden targets. Ordinary camouflage is based on anti-visible observation. The general criminals are usually concealed in the grass and woods. Due to the harshness of the wild environment and the visual illusion of people, it is easy to make false judgments. Infrared thermal imaging can detect hidden thermal targets through camouflage and grass leaves. The temperature and infrared radiation of human body and vehicle are generally much larger than the temperature of the vegetation and infrared radiation, so it is not easy to disguise and it is not easy to make false judgments.

Sixth, you can find fire hazards and achieve fire prevention monitoring. The general fire is caused by an inconspicuous igneous fire. With the existing common methods, it is difficult to find such hidden fire signs. Since the infrared thermal imager is an apparatus for imaging the surface temperature of an object, an infrared thermal imager is used to find a fire point through the smoke, so that early prevention and early suppression can be achieved.

Seventh, low power consumption and long life. Laser illumination or infrared lamps require active illumination, and the power consumption of the whole machine is relatively large. The life of ordinary infrared lamps is only about 1000 hours, the life of laser illumination is about 10,000 hours, and the life of non-refrigerated infrared thermal imagers is up to 45,000 hours.

Thermal imaging application

The application of thermal imagers can be said to be very extensive. However, the application field of domestic thermal imagers has yet to be developed, and many industries are also trying to use thermal imagers. Today, I will give you a general idea of ​​which areas can use thermal imagers? Know 10 kinds of professionals in the field of thermal imaging, more than 20 kinds of experts are experts!

1. Power industry

The first major application area is the non-electrical industry. At home and abroad, the inspection of the power industry is inseparable from the detection of thermal imagers, which not only ensures the comprehensiveness of the inspection, but also ensures the safety of the inspection personnel!

2. Petrochemical industry

Anyone who has worked in the petrochemical industry knows that many petrochemical production equipment are carried out under high temperature and high pressure. It is very important to monitor the high temperature and high pressure equipment such as the reaction furnace in real time during the production process.

3. Public security check

Public places, especially airports, stations and other places, have large interference to visible light cameras at night, and infrared thermal imaging monitoring can make up for this deficiency.

4. National defense field

The aircraft's photoelectric pods, tank infrared thermal imaging systems, and border patrols play a very important role.

5, forest fire prevention

In the recent fires, the forest fire prevention system has been able to monitor the weather 24 hours after it has been added to thermal imaging. It has found that the fire hazard is strong and can prevent it.

6, target tracking

At night, if artificial lighting is used, it is easy to expose the target. If a low-light-level night vision device is used, it also works in the visible light band and still requires external light illumination. The infrared thermal imager passively accepts the target's own infrared thermal radiation, passive imaging, can work normally day and night, and will not expose itself.

7, security field

The field of security monitoring has been rapidly developed in China, and infrared thermal imaging is not affected by light. All-weather monitoring has become a major selling point of thermal imaging.
