Device for identifying person with abnormal body temperature from crowd

Abstract

The invention belongs to the technical field of non-contact body temperature detection, and particularly provides a device for identifying a person with abnormal body temperature from a crowd. The invention aims to solve the problem that the person with abnormal body temperature cannot be identified from the crowd in the prior art. Therefore, the invention provides the device for identifying the person with abnormal body temperature from the crowd, which comprises an infrared detection module and a controller which are connected with each other, wherein the infrared detection module is used for acquiring images of the crowd, acquiring body temperature gray values of each person in the images and sending each acquired body temperature gray value to the controller; the controller is used forcalculating the average value of all the body temperature gray values and calculating the difference value between each body temperature gray value and the average value, and judging the body temperature of the person corresponding to the body temperature gray value to be abnormal when the difference value reaches a preset threshold value.

Description

technical field [0001] The invention belongs to the technical field of non-contact body temperature detection, and specifically provides a device for identifying people with abnormal body temperature from a crowd. Background technique [0002] During the period of high incidence of flu, people are often unable to know that they have flu or fever at the first time. They often go to clinics and hospitals for diagnosis and treatment only after their body temperature is already high and their bodies are in condition. Firstly, the best opportunity for treatment is missed, and secondly, it will be transmitted to the people around. Especially in a closed environment (such as a teacher, an office), as long as one person has the flu, other people are also easily infected. [0003] There is no device in the prior art that can identify a person with abnormal body temperature from the crowd, so that the person can be treated and isolated in time. [0004] For this reason, there is a n...

Problems solved by technology

[0005] In order to solve the above problems in the prior art, that is, in order to solve the problem in the prior art that people with abnormal body temperature cannot be identified from the crowd, the present invention provides a device for identifying people with abnormal body temperature from the crowd. It includes an infrared detection module and a controller connected to each other, the infrared detection module is used to obtain the infrared image of the crowd, and obtain the body temperature gray value of each person in the infrared image, and each of the acquired The body temperature gray value is sent to the controller; the controller is used to calculate the average value of all the body temperature gray values ​​and calculate the difference between each of the body temperature gray value and the average value, and in the When the difference reaches the preset threshold, it is determined that the body temperature of the person corresponding to the gray value of the body temperature is abnormal
