Thermal imaging temperature measurement gatekeeper is an active temperature measurement method that does not require the object to be detected within a specified range. When pedestrians pass by the detection lens, temperature measurement is achieved. This temperature measurement technology is similar to a surveillance camera system, which can simultaneously detect the body temperature of a group of people. Unlike conventional monitoring, thermal imaging temperature measurement products can display thermal images of human body temperature, making it convenient for staff to intuitively understand people's temperature situation. It can achieve temperature screening and detection of distant, multi-target, and large areas. For example, in places with high traffic such as subways, customs, airports, and high-speed trains, queuing up for inspection one by one is very inefficient. Thermal imaging temperature measurement products, based on technological segmentation, can simultaneously detect multiple people and quickly identify objects with body temperature exceeding the standard in the crowd. After early temperature screening, abnormalities are detected and further confirmed. It is a safe, convenient, and highly efficient temperature screening method.
The drawback of the thermal imaging temperature measurement gatekeeper is that it has high requirements for the external environment, and temperatures that are too cold or too hot can affect the temperature measurement data of the system. Taking the current northern region as an example, outdoor temperatures are generally cold in winter, and the surface temperature of the human body will also decrease accordingly. At this time, even if someone in the crowd has a fever, thermal imaging temperature measurement products cannot recognize it, resulting in misjudgment.
By comparing and analyzing the working principles, performance, prices, and applicable scenarios of infrared temperature measurement products and thermal imaging temperature measurement products, it is necessary to start from reality and select suitable temperature measurement equipment based on the application scenarios when selecting temperature measurement equipment. It is recommended to prioritize the use of infrared temperature measurement products without requiring detection speed and pass rate. This type of product has strong ability to cope with complex environments, more guaranteed accuracy, and is cost-effective. If the external environment is relatively ideal and the personnel density is high, and rapid detection and prevention are needed, it is recommended to choose a thermal imaging temperature measurement gate machine.
