Individual body temperature anomaly screening method, device and equipment

Abstract

The invention discloses an individual body temperature anomaly screening method. The method comprises the steps of acquiring infrared radiation data of a target group by using infrared detection equipment within a preset distance range; performing average value operation on the infrared radiation signals corresponding to each target individual in the target group contained in the infrared radiation data to obtain an average value of the infrared radiation signals of the target group; performing difference operation on the infrared radiation signal corresponding to each target individual and the average value of the infrared radiation signals to obtain a radiation difference corresponding to each target individual; and judging whether a target individual of which the corresponding radiationdifference value exceeds a preset threshold range exists in the target group, and if so, determining that the target individual of which the corresponding radiation difference value exceeds the preset threshold range is an individual with abnormal body temperature. According to the method, errors generated by the external environment on screening of individuals with abnormal body temperature areeliminated, and the operation process is simple. The invention further provides a device and equipment for screening the abnormal body temperature of individuals, and the device and equipment have theabove beneficial effects.

Description

technical field [0001] The present invention relates to the technical field of body temperature detection, in particular to a screening method, device and equipment for abnormal body temperature of individuals. Background technique [0002] For humans and other warm-blooded animals, whether the body temperature is normal or not is one of the important indicators for judging whether the body of a human or warm-blooded animals is healthy. And in the symptoms of many diseases, there are fever symptoms. Therefore, measuring body temperature is often used as one of the important means to initially check whether an individual is infected with infectious diseases such as new coronary pneumonia accompanied by fever symptoms. [0003] At present, the most commonly used method of measuring human body temperature is to use an infrared thermometer to measure the skin temperature of the human body's wrist or forehead. The main principle is that the infrared detector in the infrared the...

Problems solved by technology

[0004] However, when actually measuring the body temperature of the human body, the infrared detector can not only sense the infrared light radiated from the human body itself, but also sense the infrared light radiated from the infrared light in the environment to the human body, which leads to the human body temperature measured by the infrared thermometer. There is a large error in body temperature, and the size of the error in different environments is also different, which affects the accurate screening of whether the body temperature is normal
