Application of Infrared Thermal Imaging Technology in Civil Field

Jul 26,2022
Since the advent of the first infrared thermal imaging camera, infrared thermal imaging technology has been first used in the military field. From the perspective of strengthening their own defense capabilities and improving the level of night warfare, many countries not only incorporate infrared thermal imaging technology as an important part of modern weapons and equipment into their national defense construction and development strategies but also continue to increase human and material resources for research, making infrared thermal imaging technology. The continuous development of technology has led to the gradual reduction of unit price and further improvement of performance, which has also achieved rapid development in the civilian field.

Application of infrared thermal imager in the civil field

Infrared imaging can be used in infrastructure construction, urban management, industrial production, traffic control, resource exploration, inspection and quarantine, fire security, and other fields, and the market demand is broad. Due to its wide application and great convenience for production and life, the market demand for infrared imaging may maintain a sustained and stable growth trend in the future. In addition to traditional application industries, there will be more emerging market demands that will become a new growth point for the infrared imaging market.

1 Civil aviation

With the continuous development of modern aviation science and technology, the safety of civil aircraft is getting higher and higher. After being equipped with an integrated environmental monitoring system, the aircraft can provide the crew with comprehensive ground and air traffic, flight meteorology, complex landforms, and other information, so that the ability to perceive the air environment is continuously enhanced. However, the ISS system only solves the safety problems of the aircraft when flying in the air, but it cannot provide effective solutions for the safety problems of landing and being located on the runway under conditions of low visibility such as heavy fog or thunderstorms and bad weather.

The existing ISS system has two defects: first, the pilot cannot fully understand the runway situation when the aircraft lands; second, the aircraft cannot detect and recognize the surrounding environment when moving on the runway, so collisions with other aircraft often occur. , Injury to ground staff and other accidents. This deficiency can be compensated by adding an infrared assist system under the front of the aircraft. Since infrared thermal imaging technology can detect and identify the runway and the surrounding environment, the take-off and landing level of the aircraft can be improved by navigating with infrared visual images, thereby improving the safety of aircraft take-off and landing.

At the same time, the light source environment of the airport is relatively complex, so the image is easily disturbed by the night light when relying on visible light for imaging monitoring. When an alarm is triggered, it is possible that the event that caused the alarm cannot be seen because the effect of the monitoring image is disturbed, and the original effect cannot be achieved. An effective way to solve this problem is to use infrared thermal imaging technology. Because it belongs to passive imaging, it is not affected by the airport environment such as rain, snow, fog, haze, and night lights, and can be used normally during the day and night.

2 Electricity field

The electric power industry is currently the most mature and stable application in the field of preventive detection. As the most effective online power detection method, infrared thermal imaging technology can quickly repair power equipment, thereby effectively reducing the time cost of equipment maintenance and improving the reliability of equipment operation.

There are many advantages of using infrared thermal imaging for power detection: it is far away from the equipment and has strong safety; non-contact temperature measurement does not affect the operation of the equipment; fast scanning speed saves time; wide temperature measurement range and high accuracy; Device defects were found. Power generation, distribution, and substations in important areas can be equipped with high-end infrared imaging monitoring equipment.

3 Petrochemical field

Many important types of equipment in the petrochemical industry need to work in high-temperature and high-pressure environments, which is prone to potential safety hazards. According to the requirements of safety production, it is necessary to monitor it in real-time to eliminate hidden dangers in time. Infrared thermal imaging technology can be used to detect corrosion, cracks, thinning, blockage, and gas leakage of product conveying and pipelines, refractory and thermal insulation materials, and various reactors, so as to collect relevant detection information.

Early gas leak detection methods employed mechanical probes that required close or close contact with the target being inspected. Detectors may be exposed to invisible harmful chemicals, and this detection method has special requirements for the detection of environmental conditions, which is not conducive to real-time detection. With the continuous progress of infrared technology, the gas leakage monitoring technology based on infrared thermal imagers will gradually become popular. Thermal imaging cameras can use images to visualize leaking gases to quickly pinpoint leaks in real-time.

4 Forest fire prevention and environmental monitoring

The surface temperature information of the object can be extracted and quantified from the target image observed by the thermal imaging camera. This feature can be used in the field of fire prevention. The high-sensitivity infrared thermal imager can perform real-time analysis of the monitoring target by setting the upper limit of the target temperature. If the target temperature reaches the set upper limit, an alarm message will be issued, so that the location and scale of the fire point can be quickly determined, and the forest fire can be eliminated in the budding stage, thereby eliminating the fire hazard.

At the same time, thermal imaging cameras can also be used for environmental monitoring. Industry regulatory enforcement agencies use thermal imaging cameras for gas leak detection to monitor industries, ensure compliance with regulations, and are responsible for auditing their emissions reduction performance. Infrared thermal imaging cameras can also play an important role in the prevention of straw burning pollution in environmental protection.

5 Medical field

The human body itself is also a source of infrared radiation, and its tissue cells generate heat and transmit it to the body surface in the process of metabolism. When the physiological condition of a certain part of the human body changes or changes, the surface temperature of that place will deviate from the normal value. , the medical infrared thermal imager can draw this part of the change into a temperature map. As a non-invasive, non-contact, non-radiation, and green auxiliary diagnostic technology, medical infrared thermal imaging has the characteristics of high sensitivity, comprehensiveness, and speed, and can play a role in early screening, early diagnosis, and full dynamic monitoring. To achieve the purpose of "preventing disease".

It is known as the five major medical imaging technologies together with nuclear magnetic resonance, CT, X-ray, and ultrasound. The main applications of medical infrared thermal imaging technology include physical identification, chronic disease prevention/control (elderly health care), major disease prevention, common disease diagnosis, comprehensive evaluation of sub-health, rehabilitation services, mental health inspection, TCM syndrome differentiation and efficacy evaluation, etc. The application of this technology in the medical field has just started, and our society will gradually enter the elderly society, so the infrared thermal imager has a huge application market in the medical field.

6 Security monitoring

High-end infrared imaging equipment has the advantages of strong concealment, low false alarm rate, and no need for any auxiliary light source at night.

Ports, airports, nuclear power plants, etc. are important areas that are prone to theft and even terrorist attacks. The use of thermal imaging cameras can play an important role in protection. Airports, hydroelectric power plants, refineries, oil and gas pipelines, and any other large infrastructure may have enclosure boundaries that can be several kilometers long. At this point, thermal imaging cameras can provide them with a safe perimeter alarm solution. During the SARS period in 2003, the security check had already

7 Maritime field

Infrared thermal imaging technology is efficient and practical in the marine environment and can meet the needs of the following customers: port, waterway and coastal security, maritime security, maritime illegal entry detection, maritime law enforcement, anti-piracy and threat detection, fishing fleet protection, ship tracking, and observation, search and rescue operations, and environmental protection. Even objects that cannot be detected by radar systems (such as sailboats, wooden boats, and floating objects) can be detected using infrared thermal imaging technology.

Thermal imaging cameras can provide an "early warning system" for common hazards, showing invisible thermal energy from potential hazards, including floating objects, airline traffic, anchored ships, and small boats; Man-made structures such as piers can also identify icebergs and shallow swimming whales.

Thermal imaging cameras can help oil tankers navigate ice-covered waters safely, see everything at night, and see any detail on other ships, including cockpits, bridges, anchors, and more. At the same time, it can also be used for maritime search and rescue missions. Search and rescue personnel can use infrared thermal imaging cameras to accurately find and locate victims, and then successfully carry out underwater search and rescue work. Infrared thermal imaging technology can also help maritime personnel understand the dynamics on land, delineate alert areas around crime scenes or search areas, and provide law enforcement officers on land with observed information, which is conducive to maritime and coastal law enforcement officers. Safe cooperation.


After years of accumulation, infrared thermal imaging technology has realized functional modularization, miniaturization, electrification, and full automation, and has the characteristics of high sensitivity, fast response speed, harmless to the human body, easy maintenance of products, and long service life.
