In addition to measuring temperature, infrared thermal imaging technology has other applications

　　Due to the spread of the epidemic throughout the country,the market for infrared security equipment related to thermal imaging has increased significantly.It is widely used in airports,railway stations,passenger stations and other crowded places.Through infrared thermal imaging and temperature measurement technology,the temperature screening of the past population is carried out to further strengthen the security work,so as to effectively control the epidemic,prevent the rapid spread of the epidemic and ensure the safety of personnel in the area.

　　Compared with hand-held thermometer,infrared thermal imager has many advantages:

　　First,non-contact temperature measurement,which can directly measure the body temperature of exposed parts of the human body such as the forehead by observing the crowd through the thermal imaging device,so as to avoid direct contact between medical staff and patients;

　　Secondly,the temperature measurement accuracy is high,and the temperature measurement accuracy of infrared medical thermal imager can reach±0.5℃.Many companies also provide infrared temperature measuring equipment with temperature accuracy of±0.3℃and±0.2℃.

　　In addition,infrared thermal imaging is not affected by weather and light conditions.Therefore,in addition to temperature screening,it can also be widely used in security monitoring,fire alarm,outdoor search and rescue and so on.

　　1.In the low illumination environment at night,the traditional monitoring often adopts the equipment assisted by active light source to achieve the monitoring effect.

　　Infrared thermal imaging device is a passive imaging device,which can accurately image without being illuminated by any light source.It is not affected by light and improves the attack intensity of night security monitoring.Because the infrared wave is long,it has the characteristics of"smoke and fog".Infrared thermal imager can better realize the monitoring and identification in harsh environment,and can realize networking,remote monitoring and 24-hour all-weather monitoring.

　　In addition,the product can also provide high contrast images and improve the reliability of video analysis.The infrared security monitoring system can realize intelligent automatic analysis,and the visible light monitoring intelligent analysis function can be used for infrared thermal video.

　　2.Fire prevention,alarm and outdoor search and rescue

　　After the fire is put out,it is easy to revive and rekindle.The thermal imager can display the temperature field of the object.Through the monitoring of the temperature field,the abnormal temperature can be found immediately to prevent the secondary fire caused by the abnormal temperature.

　　Outdoor search and rescue,remote detection and search of trapped persons,and thermal imaging within a few kilometers can easily find trapped persons and accident vehicles falling into deep ditches and cliffs.

　　In addition,UAVs equipped with video and infrared thermal imaging equipment can also perform effective search and rescue tasks in accidents such as fire.

　　3.Early warning and monitoring of dams,lakes and mountains

　　The infrared thermal imager can realize the all-weather monitoring of the reservoir dam under bad weather conditions such as rain,snow,smoke,fog and haze,monitor the leakage point,monitor the crack and collapse,and monitor the size of water flow.Because the water temperature is lower than the ambient temperature,the emissivity of water is different from that of surrounding objects.Even at the same temperature,water can be decomposed.Landslides can also be monitored from a distance and given early warning.

　　Compared with the period of SARS in 2003,the core components of infrared thermal imager are imported.In this epidemic,China has basically achieved self-sufficiency and made important contributions to personnel flow screening and epidemic prevention and control.In the future,on the premise of fully developing its related applications,the market potential of infrared thermal imaging technology needs to be tapped.
