Application of thermal imaging technology in the national economy

Thermal imaging can give information on the surface thermal radiation of the object and its internal heat dissipation, thus becoming a new means for people to observe and perceive the objective world. Thermal imaging technology is the best choice when it is necessary to observe the thermal image of an object, to obtain a temperature profile of the object without contact, and to observe the object at night. Therefore, thermal imaging technology is also widely used in paramilitary and civil applications.

In the aerospace field, meteorological satellites, resource remote sensing satellites, Earth observation satellites, infrared astronomical observation satellites, etc. use thermal imaging technology for weather forecasting, disaster mitigation and prevention, crop growth monitoring, yield assessment, pest and disease forecasting, forest fire prevention, land survey, resource survey , district city planning, environmental pollution monitoring, scientific research, etc., these applications have a major impact on the national economy. China is a country with frequent natural disasters. Using satellites to monitor changes in the environment and timely issuing forecasts can reduce the loss of people's lives and property. Chinese scientists have used the infrared image of the satellite to find out that before the earthquake, the temperature of the air above the earthquake zone will rise, and the so-called "redness" phenomenon will appear. The use of this phenomenon for earthquake prediction is currently being studied and there have been successful examples. In the areas of land survey, resource survey, district city planning, environmental pollution, forest fire prevention, etc., the use of satellite thermal images can provide macro, comprehensive, dynamic, timely and uninterrupted information, providing a basis for the country's macro and control. Satellite thermal imaging devices can be used for scientific research in ocean currents, volcanoes, icebergs, vegetation on the earth, thermal balance of the Earth, etc., enabling humans to better understand nature. In short, thermal imaging technology has developed into a high-tech that has a major impact on national economic interests and security.

In the industrial sector, there are many applications for thermal imaging technology. The power sector has used the thermal imager to perform live detection on transmission lines, transformers, etc., which can detect hidden troubles in time and play a very good role in ensuring power supply. In the metallurgical department, the thermal imager is used to check the temperature distribution of the furnace body in order to detect the corrosion of the lining in time and organize the repair. In the petroleum and chemical sectors, thermal imaging cameras are used to check the temperature distribution and leakage of reaction towers and pipelines. In the building and building materials sector, thermal imaging cameras are used to check the heat leakage of buildings in order to take energy-saving measures to reduce the energy consumption of heating and air-conditioning systems, improve economic efficiency and reduce environmental pollution. In the transportation sector, thermal imaging cameras have been used for night driving and navigation of aircraft, especially at low altitudes. The thermal imager is used to check the axle of the train to prevent overheating. Trains equipped with thermal imaging cameras can sail at night and in fog, avoiding collisions. Vehicles equipped with thermal imaging cameras can avoid rear-end collisions on the highway in foggy weather and ensure safe driving at night.

In the medical field, thermal imaging cameras have been the early diagnosis of cancer, the standard means of diagnosis of skin, bones, blood vessels and other diseases, and now they are used to monitor the heart and blood vessels of patients in surgery, in order to find abnormal phenomena and take timely measures.

In scientific research, thermal imaging cameras are used for non-contact temperature profile measurements, thermal radiation measurements, astronomical observations, and wildlife nighttime activities. In addition, thermal imagers are useful in aerospace resource exploration, non-destructive testing in manufacturing, non-contact temperature profile measurements, organic chemical gas analysis, pollution detection and control.

In the public security department, thermal imaging cameras can be used for security surveillance, searching for evidence of crimes, finding personnel and fire sources in firefighting, customs smuggling, and anti-smuggling at borders. It is an effective technical means to combat crime and protect public safety. With the development of thermal imaging technology and people's deep understanding of thermal imaging cameras, new areas of more applications will be developed.
