The advantages, features and technical methods achieved by the present invention will be described in more detail with reference to exemplary embodiments and accompanying drawings to make it easier to understand, and the present invention can be implemented in different forms, so it should not be understood as the present invention Only the embodiments set forth herein are limited. On the contrary, for those of ordinary skill in the art, the provided embodiments will make this disclosure more thorough, comprehensive and fully convey the scope of the present invention, and the present invention will only be As defined by the appended claims.

In addition, the terms "comprising" and/or "comprising" refer to the presence of stated features, regions, integers, steps, operations, elements and/or parts, but do not exclude one or more other features, regions, integers, steps, operations , the presence or addition of elements, parts and/or combinations thereof.

In order to make it easier for your examiners to understand the content of the present invention and the effects that can be achieved, the specific embodiments listed in the drawings are described in detail as follows: Please refer to Figure 1, which is a schematic diagram of the component configuration relationship of the present invention . As shown in the figure, the present invention is mainly composed of a basic thermal sensing module 10, a reference thermal sensing module 20 and a processing module 30, wherein the basic thermal sensing module 10 and the reference thermal sensing module 20 are all related hardware or software due to a region sensing temperature value, and the processing module 30 is used to process the received data, and after comparing, calculating or analyzing the data, the corresponding The hardware or software that generates the associated signal.

In this way, the basic thermal sensing module 10 in this embodiment is set in a basic temperature zone, and the basic temperature zone specifically refers to the position where the user wants to measure people passing through or entering the zone, For example, adjacent to the gate in the building (ie, the indoor environment area). So when people enter the base In the temperature zone, the basic thermal induction module 10 can provide a basic thermal induction wave 11 towards the basic temperature zone, so as to detect a basic temperature 12 of the human body according to the information fed back by the basic thermal induction wave 11, A basic ambient temperature 13 around the human body will be further detected.

Due to the difference in temperature between the outdoor temperature and the indoor temperature, when people enter the room from the outside, their body temperature may be higher or lower than their own body temperature due to the influence of the outdoor temperature, so in order to avoid In the above situation, the reference thermal sensing module 20 is set at a position of a reference temperature zone. The reference temperature zone referred to here is adjacent to the position of the base temperature zone, but there is indeed a considerable temperature difference between them. (that is, when the base temperature zone is the area inside the building and adjacent to the gate, the reference temperature zone can be the area outside the building and adjacent to the gate (ie, the outdoor environment zone)). In this way, for example, when people enter the reference temperature zone before entering the base temperature zone, when the reference thermal sensing module 20 provides a reference thermal sensing wave 21 toward the reference temperature zone, the reference thermal sensing module 20 can detect a reference temperature 22 of the human body and a reference ambient temperature 23 around the human body according to the information fed back by the reference thermal induction wave 21 .

It can be seen that, in addition to detecting the temperature of the human body, the above-mentioned basic thermal sensing module 10 and the reference thermal sensing module 20 will also detect the ambient temperature around the human body as data for subsequent calculation and analysis.

The processing module 30 can specifically be a central processing unit or other devices capable of data processing. When the processing module 30 is connected with the basic thermal sensing module 10 and the reference thermal sensing module 20, the processing The module 30 can receive the base temperature 12, the base ambient temperature 13, the reference temperature 22, and the reference ambient temperature 23. Because when the ambient temperature is different, the human body temperature may have an actual body temperature due to the temperature difference. Therefore, the processing module 30 can first compare a temperature difference value 31 between the base ambient temperature 13 and the reference ambient temperature 23 to determine whether the two different environments are Whether there will be a temperature difference, if the basic ambient temperature 13 and the reference ambient temperature 23 have the temperature difference value 31, it can be preliminarily determined that the body temperature of the human body may be due to the ambient temperature difference between the basic temperature zone and the reference temperature zone. difference. However, when the temperature difference between the basic ambient temperature 13 and the reference ambient temperature 23 is extremely small, it is difficult to affect the body temperature directly or occasionally, so the processing module 30 here can be further set according to a A reasonable deviation value 32 (such as 3 degrees, 5 degrees, or more than 10 degrees, the reasonable deviation value is set under different conditions of the environment) to judge the temperature difference value 31, when the temperature difference value 31 exceeds the reasonable deviation value 32 , the processing module uses the deep learning algorithm to calculate the temperature difference 31, the base temperature 12 and the reference temperature 22, and perform subsequent judgment actions, but when the temperature difference 31 does not exceed the reasonable deviation value At 32, the processing module 30 continues to receive another set of the base temperature 12 , the base ambient temperature 13 , the reference temperature 22 and the reference ambient temperature 23 .

And when the processing module 30 uses the deep learning algorithm to calculate the temperature difference value 31, the base temperature 12 and the reference temperature 22, the processing module 30 in this embodiment can use the temperature difference value 31 A reasonable temperature difference range 33 is calculated, and the reasonable temperature difference range 33 refers to the reasonable temperature difference range 33 on body temperature change after the human body enters from the reference ambient temperature 23 to the basic ambient temperature 13, for example, when the When the reference ambient temperature 23 is 13 degrees, the body temperature of the human body may drop by 2 degrees correspondingly due to the temperature environment of 13 degrees (for example, the actual body temperature is 37 degrees, and the drop is 35 degrees), the basic ambient temperature 13 is At 27 degrees, because the person has just entered from a temperature environment of 13 degrees to a temperature environment of 27 degrees (that is, the temperature difference value 31 is 14 degrees), so when the temperature of the return temperature is assumed to be 0.5 degrees, the processing module 30 It can be judged that when the basic ambient temperature 13 is 27 degrees, the body temperature of the human body will correspondingly rise by 0.5 degrees. Therefore, in the judgment of this example, based on the temperature difference value 31 being 14 degrees, the reasonable temperature difference range 33 should be is 0.5 degrees.

In addition, due to the different physical fitness of each person, there may be differences in the temperature recovery speed or the cooling or heating up due to the external environment, so this is based on 0.5 degrees of the reasonable temperature range 33, and then through According to the factor that the human body temperature drops by 2 degrees due to the temperature environment of 13 degrees, the reference data of the temperature difference of 1.5 degrees can be obtained after subtracting 0.5 degrees of the reference temperature from the 2 degrees of the drop. In this way, according to the measured After adding 1.5 degrees to the base temperature 12, an actual temperature value 34 (ie 37 degrees) can be calculated.

In this way, the processing module 30 can judge whether it is in a reasonable temperature range 35 (such as 35.7 degrees to 37.9 degrees) according to the calculated actual temperature value 34, and if so, the processing module 30 continues to judge another group The temperature difference 31 , the base temperature 12 and the reference temperature 22 , if not, the processing module 30 generates an abnormal signal 36 .

The warning device 40 is connected with the processing module 30 to receive the abnormal signal 36, and executes a warning operation 41 according to the abnormal signal 36, so as to remind the user that the temperature of the measured object exceeds the reasonable temperature range 35 situation occurs. Wherein, the warning device 40 can include a display module, a lamp, a speaker, a combination of any two or more thereof, or any related device that can output the abnormal signal. After the abnormal signal 36 is generated, the warning device 40 can receive the abnormal signal 36 by being connected to the processing module 30, and output the abnormal signal 36 to the driver to listen to (such as a loudspeaker), and mark the abnormal signal 36 beyond the Objects with a reasonable temperature range 35 (such as display screens) or warning lights (such as lamps) can be used to inform drivers. Obviously, the way the above-mentioned components (display modules, lamps and speakers) output the abnormal signal 36 does not There is no conflict, so when the warning device 40 is, for example, a combination of a loudspeaker and a display screen, it can output warning sounds (or voices) and display its objects at the same time.

One of the registers 50 can also be connected with the processing module 30 for storing the base temperature 12, the base ambient temperature 13, the reference temperature 22, the reference ambient temperature 23, the temperature difference value 31, the reasonable The temperature range 35 , the temperature difference value 31 , the abnormal signal 36 or a combination thereof.

Please refer to FIG. 2 again, which is a schematic diagram of the arrangement relationship of components of the temperature setting module of the present invention. As shown in the figure, in order to provide more accurate parameters, so that the processing module 30 can calculate the actual temperature value 34 more accurately, so the processing module 30 can further be connected with a temperature setting module 60 , wherein the temperature setting module 60 is used to connect with an external electronic device 70 to obtain the reasonable temperature difference range 33 of the temperature difference value 31 from the external electronic device 70, or by providing a setting interface 61 In a manner, the reasonable temperature difference range 33 set by the user is received, and the reasonable temperature difference range 33 is transmitted to the processing module 30 . In this way, by continuously learning and updating the parameters of the reasonable temperature difference range 33 , the processing module 30 can effectively calculate the actual temperature value 34 according to the reasonable temperature difference range 33 .

Please refer to FIG. 3 again, which is a schematic diagram of the arrangement relationship of components of the imaging device of the present invention. As shown in the figure, the present invention further includes an imaging device 80, which is specifically a device capable of presenting relevant information on a display module, so when the imaging device 80 is combined with the basic thermal sensing module 10 and the processing module When the group 30 is connected, the imaging device 80 will be set in the basic temperature zone to obtain a human body image 81 of the human body, and after receiving the basic temperature 12 of the human body from the basic thermal sensing module 10 , the human body image 81 and the basic temperature 12 can be correspondingly displayed on a display module, so that the display module can simultaneously display the measured basic temperature 12 of the human body and the calculated The actual temperature value 34 and the human body image 81 .

Please refer to FIG. 4 again, which is a flowchart of the steps of the present invention. As shown in the figure, the present invention can be realized mainly according to the following main steps, which include: S101: the basic thermal induction module is located in the basic temperature zone to provide the basic thermal induction wave towards the basic temperature zone, and Detect the basic temperature of the human body and the basic ambient temperature around the human body based on the basic thermal induction wave; S102: The basic thermal sensing module detects the basic temperature of the human body and the basic ambient temperature around the human body according to the basic thermal sensing wave; S103: The reference thermal sensing module is located in the reference temperature zone to provide reference thermal sensing towards the reference temperature zone wave; S104: the reference thermal sensing module detects the reference temperature of the human body and the reference ambient temperature around the human body according to the reference thermal sensing wave; S105: the processing module compares a temperature difference between the basic ambient temperature and the reference ambient temperature; S106 : If there is a temperature difference between the basic ambient temperature and the reference ambient temperature, the processing module further uses a deep learning algorithm to calculate the temperature difference, the basic temperature, and the reference temperature to generate a reasonable temperature difference range; S107: The processing module calculates the temperature difference according to the reasonable temperature difference range Calculate the actual temperature.
