the method comprises the following steps: firstly, controlling image acquisition modules (10) and/or iris identification modules in a plurality of sets of identification detection units (3) to simultaneously acquire mark information and/or iris information of a plurality of detected persons, and then comparing the acquired mark information and/or iris information with the mark information and/or iris information stored in a storage module (11) to identify the identity information of the currently detected person;
step two: controlling infrared temperature probes (4) and infrared distance probes (5) in a plurality of sets of identification detection units (3) to simultaneously acquire body temperature information and distance information of a plurality of detected persons and sending the acquired body temperature information and distance information to a processing module (9);
step three: the processing module (9) calculates the body temperature values of a plurality of detected persons according to the received body temperature information and the distance information, after the body temperature values of the detected persons are obtained, on one hand, the body temperature values are displayed through the display alarm module (12), and if the body temperature values of the detected persons exceed a set value, the display alarm module (12) gives out voice alarm; on the other hand, the processing module (9) stores the body temperature value of the detected person in the storage module (11) and finishes the detection of the current detected person.
6. The method as claimed in claim 5, wherein the body temperature detecting method comprises: the mark information and/or the iris information stored in the storage module (11) are obtained by the person to be detected through registration in advance through the image acquisition module (10) and/or the iris recognition module.
7. The method as claimed in claim 5, wherein the body temperature detecting method comprises: the infrared temperature measurement probe (4) is an infrared array temperature sensor with 32 x 24 temperature measurement points, the processing module (9) takes data of 16 x 16 temperature measurement points in the middle during detection, then takes out the temperature between 25 and 40, takes out three highest temperature values of the forehead part, calculates an average value to obtain an original temperature, and finally fits the original temperature to obtain the actual body temperature of the detected person, and the specific calculation process is as follows:
taking the original data function: f1 ═ mat [4: -4,8: -8 ];
take the middle 16 x 16 function: f2 ═ f1[4: -4,8: -8 ];
taking the forehead part function: f3 ═ f2[0:3 ];
taking the average function of the three highest temperature values of the forehead part: f4 ═ avg (f 3);
fitting function: fixing-k 3 dis3+k2*dis2+k1*dis+k0；
And fitting according to the distance information to obtain the actual body temperature of the detected person: temp. f4+ fitting (distance).
