Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Fig. 1 is a flowchart of a temperature detection method according to an embodiment of the present invention. The temperature detection method provided by the embodiment can be applied to the temperature detection. Typically, the method can be applied to the condition of detecting the temperature of the object to be detected when the influence of the infrared radiation of an external light source exists. The method may be specifically performed by a temperature detection device, which may be implemented by means of software and/or hardware, which may be integrated in a temperature detection device. Referring to fig. 1, the method of the embodiment of the present application specifically includes:

s110, if the distance value is not detected, determining a first temperature difference value between the real-time infrared temperature and the real-time contact temperature.

In the embodiment of the present application, the temperature detection device may include an infrared temperature sensor, a contact temperature sensor, and a distance sensor. Among other things, infrared temperature sensors are used to detect infrared radiation, such as solar radiation, lamp radiation, infrared radiation generated by objects in which temperature is present, and the like. The contact temperature sensor is used to detect a temperature that can be detected by contact, such as detecting an ambient air temperature, a temperature detection device self-heating temperature, or the like. The distance sensor is used for detecting a distance value between the object and the temperature detection device. If the temperature detection device does not detect the temperature of any object, the distance sensor does not detect the object, and the distance value cannot be detected. The real-time infrared temperature is the temperature detected by the infrared temperature sensor, and the real-time contact temperature is the temperature detected by the contact sensor.

For example, when the temperature detection device does not detect the distance value, the current temperature detection device detects the temperature of the current detection environment. In this case, it is possible to accurately determine whether or not there is an influence of infrared radiation of an external light source in the current detection environment. For example, the real-time infrared temperature detected by the infrared temperature sensor is T1, and the real-time contact temperature detected by the contact temperature sensor is T2. The value of T1 is influenced by the infrared radiation of external light source. The value of T2 is affected by the ambient air temperature and the heat generation temperature of the temperature detection device in the environment, i.e., T2 is Ta + T ', where Ta is the ambient air temperature and T ' is the temperature generated by the heat generation of the temperature detection device, and if the contact temperature sensor is outside the temperature detection device, T ' is 0. If no external light source infrared radiation exists, the infrared temperature sensor detects the infrared radiation generated for the ambient air temperature, and the T1 value truly reflects the ambient air temperature, namely T1 ═ Ta. A first temperature difference between T1 and T2 is T1-T2-Ta- (Ta + T ') -T'. If the infrared radiation of the external light source exists, a large amount of infrared radiation energy exists in the environment, T1 is far larger than Ta, and the first temperature difference T1-T2 between T2 and T1 is (T1-Ta) -T', the stronger the infrared radiation of the external light source is, the larger T1-Ta is, and the larger T1-T2 is. When the external light source infrared radiation is not available, the first temperature difference between T1-T2 is-T ', T1 and T2 is small, and when the external light source infrared radiation is available, the first temperature difference between T1-T2 (T1-Ta) -T', T1 and T2 is large, and the stronger the external light source infrared radiation is, the larger the first temperature difference is, the intensity of the external light source infrared radiation can be quantified through the first temperature difference between T1 and T2. Therefore, whether the infrared radiation of the external light source exists or not and the intensity of the infrared radiation of the external light source can be judged through the first temperature difference values of T1 and T2.

S120, if the distance value is detected, acquiring a first distance value between the object to be detected and the temperature detection equipment, detecting the temperature of the object to be detected, and determining the measured temperature of the object to be detected.

The first distance value is a distance value between the object to be detected and the temperature detection equipment when the temperature detection equipment detects the temperature of the object to be detected. The distance value between the object to be detected and the temperature detection equipment can influence the value of the external light source infrared radiation entering the temperature detection equipment, when the first distance value is larger, the distance between the object to be detected and the temperature detection equipment is larger, the shielding of the external light source infrared radiation is less, the value of the external light source infrared radiation entering the temperature detection equipment is larger, when the first distance value is smaller, the distance between the object to be detected and the temperature detection equipment is smaller, the shielding of the external light source infrared radiation entering the temperature detection equipment is smaller, and the value of the external light source infrared radiation entering the temperature detection equipment is smaller. Therefore, the first distance value can reflect the amount of infrared radiation of the external light source entering the temperature detection equipment when the temperature of the object to be detected is detected.

In the embodiment of the application, the temperature of the object to be measured is detected through the infrared temperature sensor, and the measured temperature of the object to be measured is obtained. When the temperature of the object to be detected is detected, the temperature detection equipment can also absorb the infrared radiation of the external light source, if the temperature detected by the infrared temperature sensor is directly used as the actual temperature of the object to be detected, the temperature is influenced by the infrared radiation of the external light source, and detection errors exist, so that the temperature detected by the temperature detection equipment on the object to be detected is used as the measured temperature of the object to be detected, but not the actual temperature of the object to be detected.

S130, determining a target temperature correction value according to the first temperature difference value, the first distance value and a preset mapping relation.

For example, the first temperature difference value reflects an influence of infrared radiation of an external light source on temperature detection in a current detection environment, the first distance value reflects a quantity of infrared radiation of the external light source entering the temperature detection device when the temperature of the object to be detected is detected, and a target temperature correction value corresponding to the first temperature difference value and the first distance value can be determined according to the first temperature difference value and the first distance value. For example, when temperature detection is not performed in advance, a current detection environment is detected, temperature detection is performed on a target object with a known temperature to obtain a measured temperature of the target object, a temperature correction value is determined according to the measured temperature of the target object and an actual temperature of the target object, and a preset mapping relation among a temperature difference value, a distance value and the temperature correction value is established, so that when actual detection is performed, the target temperature correction value is determined according to the first temperature difference value, the first distance value and the preset mapping relation.

The preset mapping relation can be in a form of a table or a form of a relation curve, and the expression form of the preset mapping relation is not particularly limited as long as the mapping relation among the temperature difference value, the distance value and the temperature correction value can be reflected.

And S140, correcting the measured temperature of the object to be measured according to the target temperature correction value to obtain the actual temperature of the object to be measured.

In the embodiment of the application, the measured temperature of the object to be detected is corrected by adopting the target temperature correction value, so that the temperature detection error caused by the infrared radiation of an external light source is eliminated, and the accuracy of temperature detection is improved.

Fig. 2 is a flowchart of a temperature detection method according to another embodiment of the present invention. In the embodiment of the present application, details that are not described in detail in the embodiment are described in detail in order to optimize the embodiment. Referring to fig. 2, the temperature detection method provided in this embodiment may include:

and S210, if the distance value is not detected, acquiring the real-time infrared temperature, the real-time contact temperature and the corresponding acquisition time according to the preset frequency.

The preset frequency can be set according to actual conditions. When the temperature of the object to be detected is not detected, the temperature detection equipment can acquire real-time infrared temperature, real-time contact temperature and corresponding acquisition time at regular time, so that the temperature condition of the current detection environment is recorded constantly. When the infrared radiation of the external light source in the current detection environment changes, the condition of the infrared radiation of the external light source in the current detection environment can be determined in time through the real-time infrared temperature, the real-time contact temperature and the corresponding acquisition time which are acquired at regular time.

S220, determining a first temperature difference value of the real-time infrared temperature and the real-time contact temperature corresponding to the acquisition time.

For each acquisition time, a first temperature difference value of the real-time infrared temperature and the real-time contact temperature corresponding to the acquisition time is determined, so as to judge whether the infrared radiation of the external light source exists in the current detection environment and judge the magnitude of the infrared radiation of the external light source.

And S230, taking a first temperature difference value corresponding to the acquisition time closest to the moment of detecting the first distance value as a target temperature difference value.

For example, when the distance value is detected, it is determined that temperature detection is currently performed on the object to be measured. And detecting the real-time infrared temperature and the real-time contact temperature at fixed time before detecting the distance value. The real-time infrared temperature and the real-time contact temperature acquired at the time of acquiring the distance value closest to the moment can more accurately reflect the influence of the infrared radiation of the external light source in the current detection environment, so that the first temperature difference value of the real-time infrared temperature and the real-time contact temperature detected last time is used as the target temperature difference value for subsequent processing.

S240, determining the determining mode of the actual temperature of the object to be measured according to the target temperature difference value.

For example, when the target temperature difference is large, it indicates that the influence of infrared radiation of an external light source in the current detection environment is large, and if the temperature of the object to be detected is detected in the detection environment, the measured temperature of the object to be detected needs to be corrected to determine the actual temperature of the object to be detected. When the target temperature difference is smaller, the influence of the infrared radiation of the external light source in the current detection environment is smaller, if the temperature of the object to be detected is detected in the detection environment, the measured temperature of the object to be detected does not need to be corrected, and the measured temperature of the object to be detected is the actual temperature of the object to be detected.

And S250, if the target temperature difference value is larger than a preset difference value threshold, determining a target temperature correction value according to the first temperature difference value, the first distance value and a preset mapping relation.

The preset difference threshold may be set according to an actual situation, for example, when the contact temperature sensor is disposed in the temperature detection device, the preset difference threshold may be a heating temperature value of the temperature detection device, or a value greater than the heating temperature. In the case where the contact temperature sensor is disposed outside the temperature detection device, the preset difference threshold may be set to 0, or a value greater than 0. And when the target temperature correction value is determined according to the first temperature difference value, the first distance value and the preset mapping relation, wherein the first temperature difference value is the target temperature difference value.

In an embodiment of the present application, a process of constructing the preset mapping relationship includes: if the distance value is not detected, determining a second temperature difference value between the test infrared temperature and the test contact temperature; if the distance value is detected, acquiring a second distance value between the target object and the temperature detection equipment, detecting the temperature of the target object, and determining the measured temperature of the target object; determining a candidate temperature correction value according to the measured temperature of the target object and the actual temperature of the target object; and determining the preset mapping relation according to the second temperature difference value, the second distance value and the candidate temperature correction value. Determining a candidate temperature correction value according to the measured temperature of the target object and the actual temperature of the target object, including: and taking the difference value between the measured temperature of the target object and the actual temperature of the target object as a candidate temperature correction value.

For example, before the temperature of the object to be measured is detected, a target object with a known actual temperature is detected in advance, so as to determine the deviation between the measured temperature of the target object and the actual temperature of the target object under the current detection environment. Specifically, when the temperature of the target object is not detected, the infrared temperature sensor is used for acquiring the test infrared temperature, the contact temperature sensor is used for acquiring the test contact temperature, and a second temperature difference value between the test infrared temperature and the test contact temperature is determined. Under the detection environment, temperature detection is carried out on the target object, a second distance value between the target object and the temperature detection equipment is obtained, and the second distance value can reflect the value of the infrared radiation of an external light source entering the temperature detection equipment at present. Temperature detection is carried out on the target object by adopting temperature detection equipment, the measured temperature of the target object is determined, determining a candidate temperature correction value according to the measured temperature of the target object and the actual temperature of the target object, corresponding the candidate temperature correction value, the second temperature difference value and the second distance value, changing the environmental temperature of the current detection environment, for example, the infrared radiation of an external light source in the current environment, and the second distance value between the target object and the temperature detection device, thereby obtaining a plurality of groups of second temperature difference values and second distance values, detecting the measured temperature of the target object under the condition of the plurality of groups of second temperature difference values and second distance values, and determining a plurality of groups of candidate temperature correction values corresponding to the second temperature differences and the second distance values according to the measured temperature and the actual temperature of the target object, and establishing a preset mapping relation, as shown in table 1. Wherein Δ T1 and Δ T2 … … Δ Tn are second temperature difference values, L1 and L2 … … Ln are second distance values, and T11 and T12 … … Tnn are candidate temperature correction values. The candidate temperature correction value may be a difference value between a measured temperature of the target object and an actual temperature of the target object.

In the embodiment of the present application, since the current detection environment is a preset environment, parameters such as infrared radiation of an external light source in the environment, a distance value between a target object and a temperature detection device, and the like are known, that is, the second temperature difference value and the second distance value are known, in an actual detection process, the second temperature difference value and the second distance value are not detected and calculated, but a preset mapping relationship is directly determined according to the second temperature difference value and the second distance value which are known when the current detection environment is set. The method comprises the steps of presetting multiple current detection environments, namely, setting multiple groups of infrared radiation of an external light source and distance values between a target object and temperature detection equipment, knowing multiple groups of second temperature difference values and second distance values in advance, detecting the measured temperature of the target object under the multiple current detection environments, determining candidate temperature correction values corresponding to the multiple groups of second temperature difference values and second distance values according to the measured temperature and actual temperature, and establishing a preset mapping relation according to the known multiple groups of second temperature difference values and second distance values and the corresponding candidate temperature correction values.

TABLE 1

It should be noted that, in the embodiment of the present application, the preset mapping relationship is only described in a table form, and is not specifically limited to the expression form of the preset mapping relationship, and other expression forms may also be used, for example, the preset mapping relationship is expressed in a curve form, for example, a three-dimensional relationship curve is constructed according to the first distance value, the second temperature difference value, and the candidate temperature correction value, so as to express the preset mapping relationship.

In this embodiment of the application, determining a target temperature correction value according to the first temperature difference value, the first distance value, and a preset mapping relationship includes: matching the first temperature difference value with a second temperature difference value in a preset mapping relation, and matching the first distance value with a second distance value in the preset mapping relation; and if the matching is successful, taking the candidate temperature correction value corresponding to the second temperature difference value and the second distance value in the preset mapping relation as the target temperature correction value.

Illustratively, the first temperature difference value is matched with the second temperature difference value in table 1, the first distance value is matched with the second distance value in table 1, and the candidate temperature correction value corresponding to the second temperature difference value and the second distance value which are successfully matched is used as the target temperature correction value for correcting the measured temperature of the object to be measured to obtain the actual temperature of the object to be measured. Through matching, the testing environment which is the same as the current temperature detection environment and is used for establishing the preset mapping relation can be matched, and the second distance value which is the same as the current first distance value and is used for establishing the preset mapping relation can be matched, so that the target temperature correction value under the detection environment and the detection condition can be accurately determined, the measured temperature of the object to be detected is corrected, the error influence of the infrared radiation of an external light source on the temperature detection under the current detection environment is eliminated, and the accuracy of the temperature detection is improved.

In this embodiment of the application, if the first distance value cannot be completely matched with the second distance value in the preset mapping relationship, it may be that the second distance value in the preset mapping relationship is a discontinuous point, and the first distance value is not included in the second distance value, for example, the second distance value in the preset mapping relationship includes 30 centimeters, 40 centimeters and the like, but the actually detected first distance value is 35 centimeters, and the second distance value in the preset mapping relationship does not include a value matched with the first distance value. At this time, an interpolation method, for example, a bilinear interpolation method, may be adopted to interpolate the second distance value, the second temperature difference value, and the candidate temperature correction value in the preset mapping relationship to obtain more data, so that the second distance value obtained after interpolation in the preset mapping relationship can be matched with the first distance value, and a corresponding target temperature correction value is obtained. By adopting a bilinear interpolation method, only the first distance value can be interpolated in the preset mapping relationship, that is, only the second distance value in the preset mapping relationship is interpolated to obtain the first distance value, and further the target temperature correction value corresponding to the first distance value is obtained. In the preset mapping relationship, a second distance value with the smallest difference value with the first distance value is selected, and the candidate temperature correction value corresponding to the second distance value is used as the target temperature correction value. For example, the second distance value in the preset mapping relationship includes 30 centimeters, 40 centimeters and the like, the first distance value obtained by actual detection is 38 centimeters, and the difference between the first distance value 38 centimeters and the second distance value 40 centimeters is the minimum, so that the candidate temperature correction value corresponding to the second distance value 40 centimeters can be used as the target temperature correction value for correcting the measured temperature of the object to be measured.

And S260, correcting the measured temperature of the object to be measured according to the target temperature correction value to obtain the actual temperature of the object to be measured.

For example, if the target temperature correction value is a difference value between the measured temperature of the target object and the real-time temperature of the target object, the target temperature correction value may be subtracted from the measured temperature of the object to be measured, so as to obtain the actual temperature of the object to be measured.

According to the technical scheme, when the infrared radiation of the external light source in the current detection environment changes, the infrared radiation condition of the external light source in the current detection environment is determined according to the real-time infrared temperature, the real-time contact temperature and the corresponding acquisition time which are acquired at regular time. The method comprises the steps of establishing a preset mapping relation according to a pre-known target object, determining a target temperature correction value according to the preset mapping relation to correct the measured temperature of the object to be detected during actual temperature measurement, and accordingly eliminating error influence of infrared radiation of an external light source on temperature detection in the current detection environment and improving accuracy of temperature detection.

Fig. 3 is a flowchart of a temperature detection method according to another embodiment of the present invention. In the embodiment of the present application, details that are not described in detail in the embodiment are described in detail in order to optimize the embodiment. Referring to fig. 3, the temperature detection method provided in this embodiment may include:

s310, if the distance value is not detected, determining a first temperature difference value between the real-time infrared temperature and the real-time contact temperature.

S320, if the distance value is detected, acquiring a first distance value between the object to be detected and the temperature detection equipment, detecting the temperature of the object to be detected, and determining the measured temperature of the object to be detected.

S330, taking a first temperature difference value corresponding to the acquisition time closest to the moment of detecting the first distance value as a target temperature difference value.

S340, if the target temperature difference value is larger than a preset difference value threshold, determining a target temperature correction value according to the first temperature difference value, the first distance value and a preset mapping relation.

And S350, correcting the measured temperature of the object to be measured according to the target temperature correction value to obtain the actual temperature of the object to be measured.

And S360, prompting that the object to be detected is close to the temperature detection equipment through prompt information.

Illustratively, if the target temperature difference is greater than the preset difference threshold, it indicates that the influence of the infrared radiation of the external light source in the current detection environment is large. At the moment, the temperature detection equipment can prompt the object to be detected to be close to the temperature detection equipment through prompt information to perform temperature retesting. When an object to be detected is close to the temperature detection equipment, a part of external infrared radiation can be correspondingly shielded from entering the temperature detection equipment, so that the influence of the infrared radiation of the external light source of the current detection environment on the temperature detection can be reduced to a certain extent.

In the embodiment of the application, the prompt information includes audio prompt information generated by an audio prompt module of the temperature detection device, and/or visual prompt information displayed by a display screen of the temperature detection device.

Illustratively, an audio prompt module can be integrated in the temperature detection device, and audio prompt information is generated by the audio prompt module and is transmitted to the current environment through a loudspeaker, so that a person to be detected is intuitively guided, and an object to be detected is prompted to approach the temperature detection device. And/or, integrating a display screen in the temperature detection equipment, displaying visual prompt information on the display screen, such as prompt words like characters 'please approach the temperature detection equipment for retesting', and/or pictures, displaying icon indication and/or animation of the object to be detected approaching the temperature detection equipment, displaying animation process of the object to be detected approaching the temperature detection equipment, and the like, so as to intuitively guide the person to be detected and prompt the object to be detected to approach the temperature detection equipment.

S370, if it is detected that the first distance value between the object to be measured and the temperature detection device changes, performing an operation of obtaining a new first distance value between the object to be measured and the temperature detection device, performing temperature detection on the object to be measured, determining a new measured temperature of the object to be measured, and correcting the new measured temperature to obtain a new actual temperature of the object to be measured.

For example, the first distance value changes, and may be decreased when the object to be measured approaches the temperature detection device. It is also possible that in the case where the object to be measured is far from the temperature detection device, the first distance value is increased, and the subsequent operation is also performed. If the first distance value between the object to be detected and the temperature detection device is detected to be changed, the step S320-S350 is executed again, namely if the distance value is detected, a new first distance value between the object to be detected and the temperature detection device is obtained, the temperature of the object to be detected is detected, and the new measured temperature of the object to be detected is determined. And taking a first temperature difference value corresponding to the acquisition time closest to the moment of detecting the new first distance value as a target temperature difference value. And if the target temperature difference is larger than a preset difference threshold value, determining a target temperature correction value according to the first temperature difference, the new first distance value and a preset mapping relation. And correcting the new measured temperature of the object to be measured according to the target temperature correction value to obtain a new actual temperature of the object to be measured. The new actual temperature can be used as the temperature measurement result of the object to be measured. The new actual temperature can be compared with the actual temperature detected last time, and the accuracy of temperature measurement can be further analyzed. If the difference value between the new actual temperature and the last actual temperature is larger, for example, larger than a preset difference threshold value, the new actual temperature can be used as a temperature measurement result, or the prompt information prompts that the object to be measured approaches the temperature detection device again to measure the temperature again. If the difference between the new actual temperature and the last detected actual temperature is smaller, for example, smaller than or equal to the preset difference threshold, the average value of the new actual temperature and the last detected actual temperature may be used as the temperature measurement result.

For example, a preset distance may also be set, and the preset distance may be set by: and determining the detection precision of the temperature detection equipment. If the influence of infrared radiation of an external light source exists, namely the target temperature difference is larger than a preset difference threshold value, under the condition that the distance between the target object and the temperature detection equipment is the initial distance, temperature detection is carried out on the target object to obtain the measured temperature of the target object, and if the error value between the measured temperature of the target object and the actual temperature of the target object is within the detection precision range, the initial distance is used as the preset distance. If the error value between the measured temperature of the target object and the actual temperature of the target object is out of the detection precision range, reducing the distance between the target object and the temperature detection device, carrying out temperature detection on the target object to obtain the measured temperature of the target object, determining whether the error value between the measured temperature of the target object and the actual temperature of the target object is within the detection precision range or not, and taking the distance between the target object and the temperature detection device under the condition as a preset distance when the error value between the measured temperature of the target object and the actual temperature of the target object is within the detection precision range.

For example, if the new first distance value between the object to be detected and the temperature detection device is still greater than the preset distance after the prompt message prompts that the object to be detected approaches the temperature detection device, the prompt message may prompt that the object to be detected approaches the temperature detection device again until the new first distance value between the object to be detected and the temperature detection device is smaller than or equal to the preset distance, perform the operation of performing temperature detection on the object to be detected, determining a new measured temperature of the object to be detected, and correcting the new measured temperature to obtain a new actual temperature of the object to be detected.

According to the technical scheme, when the target temperature difference value is larger than the preset difference value threshold value, namely, under the condition that external light source infrared radiation exists, the prompt information prompts that the object to be detected is close to the temperature detection equipment to conduct temperature retest, the person to be detected can be guided visually, and therefore after the object to be detected is close to the temperature detection equipment, part of external light source infrared radiation is blocked from entering the temperature detection equipment, and the influence of the external light source infrared radiation on the temperature detection precision is reduced.

Fig. 4 is a flowchart of a temperature detection method according to still another embodiment of the invention. In the embodiment of the present application, details that are not described in detail in the embodiment are described in detail in order to optimize the embodiment. Referring to fig. 4, the temperature detection method provided in this embodiment may include:

s410, if the distance value is not detected, determining a first temperature difference value between the real-time infrared temperature and the real-time contact temperature.

And S420, if the distance value is detected, taking a first temperature difference value corresponding to the acquisition time closest to the moment of detecting the distance value as a target temperature difference value.

And S430, if the target temperature difference is larger than a preset difference threshold, prompting that the object to be detected is close to the temperature detection equipment through prompt information.

Illustratively, in this application embodiment, if a distance value is detected, that is, there is an object to be detected to perform temperature detection through the temperature detection device, and the target temperature difference value is greater than the preset difference value, it is determined that there is an influence of the infrared radiation of the external light source, the object to be detected is not subjected to temperature detection and temperature correction at first, but is prompted through the prompt message that the object to be detected is close to the temperature detection device until the target temperature difference value is less than or equal to the preset difference threshold value, and after the distance between the object to be detected and the temperature detection device is reduced and the influence of the infrared radiation of the external light source on the temperature detection is reduced, the temperature detection and correction are performed again.

For example, a distance threshold may also be preset, if the detected first distance value between the object to be detected and the temperature detection device is smaller than the distance threshold, it is determined that the first distance value between the object to be detected and the temperature detection device meets the requirement of the close range, the influence of the infrared radiation of the external light source on the temperature detection is sufficiently small, at this time, the subsequent operation may be performed, and if the detected first distance value between the object to be detected and the temperature detection device is greater than or equal to the distance threshold, and the first distance value between the object to be detected and the temperature detection device does not meet the requirement of the close range, the prompt information is continued to prompt that the object to be detected approaches the temperature detection device.

And S460, correcting the measured temperature of the object to be measured according to the target temperature correction value to obtain the actual temperature of the object to be measured.

According to the technical scheme, when the target temperature difference value is larger than the preset difference value threshold value, namely, under the condition that external light source infrared radiation exists, the object to be detected is visually prompted to be close to the temperature detection equipment through the prompt information, the influence of the external light source infrared radiation is reduced, then retest is conducted, therefore, the accuracy of temperature detection is improved, the step of conducting temperature detection under the condition that the influence of the external light source infrared radiation is large is saved, and the workload of temperature detection is reduced.
