The intelligent calculation module 32 receives the first After image compression is performed on an image 261, the second image 262, and the third image 263, the first image 261 and the second image 262 are then superimposed to make the second image 262 The face of the target object 101 can display corresponding temperature information, thereby warning whether the face temperature of the target object 101 exceeds the above-mentioned set temperature threshold and whether to wear a mask. The display device 40 is electrically connected to the processor 30, and the display device 40 displays the first image 261, the second image 262, and the third image 263 compressed and processed by the processor 30.

With the above structure, the present creation can detect whether a mask is worn while detecting the body temperature of the target object 101, thereby achieving the effect of enhanced screening.

Continuing to refer to Fig. 1 and in conjunction with Fig. 3, the processor 30 is electrically connected to a warning device 50. When the body temperature of any of the target objects 101, 102, 103 exceeds the above-mentioned set temperature threshold or does not wear a mask, a warning effect is generated. It can be sound or light prompt.
