However, the external blackbody is inconvenient to deploy and requires additional supporting facilities and space to install the blackbody, and the blackbody only provides one temperature reference point and cannot realize simultaneous calibration of multiple temperature points. In addition, since the external blackbody must always be located within the field of view of the infrared temperature measurement system, in the case of a special application such as long-time infrared monitoring in a state where a part of the field of view is covered, monitoring target information is lost. How to realize accurate simultaneous calibration of multiple temperature points and how to position the calibration blackbody, simplify the structure of the infrared temperature measurement module, realize the self-adaptive function of the external blackbody, and ensure that the external calibration blackbody does not obscure the measurement object Problems such as preventing it from happening are technical problems that need to be solved urgently by those skilled in the art.

As shown in FIG. 3 , which is a diagram showing the surface of a blackbody radiation source 1 , in this specific embodiment, the surface of the blackbody radiation source 1 facing the sensing module 2 has two areas, area A and area B, respectively. There are two regions, and the two regions have different emissivities. Therefore, when the temperature of the blackbody radiation source 1 is controlled to a certain set temperature, the infrared radiation energy emitted by the two regions is different, and the two regions have different apparent temperatures. For example, if the temperature of the blackbody radiation source 1 is controlled to reach the set temperature T1, the apparent temperature of the A region becomes T2 and the apparent temperature of the B region becomes T3, where the apparent temperature T2 and the apparent temperature T3 is not equal, and the set temperature T1 of the blackbody radiation source 1 may be equal to the apparent temperature T2, may be equal to the apparent temperature T3, or may not be equal to both the apparent temperature T2 and the apparent temperature T3.

For example, the infrared detector 22 is a single-band detector or a multi-band detector of different wavelengths, such as short wave, medium wave, and long wave. The multi-band infrared detector can realize multi-band image fusion by simultaneously acquiring image information in different bands of the measurement object.

In this specific embodiment, the sensing module 2 includes one optical lens 21 and one said infrared detector 22 , but in another specific embodiment of the present invention, the sensing module 2 includes a plurality of of an optical lens 21 and a plurality of infrared detectors 22 . For example, in the infrared temperature measurement and monitoring system of the present invention, a single-band infrared detector of a plurality of different bands can simultaneously acquire image information in different bands of a measurement object to realize multi-band image fusion.

The data processing module 3 can realize calibration for the infrared temperature measurement and monitoring system by forming calibration data according to the electrical signal formed by converting the apparent temperature and the infrared radiation corresponding thereto, and also the data of the detection module can be processed to obtain characteristic information of the measurement object.

In a specific embodiment of the present invention, the position control unit 4 is a telescoping mechanism that is stretchable with respect to the sensing module 2 so that the position of the blackbody radiation source 1 with respect to the sensing module 2 is changed. When performing temperature calibration using the calibration module, the position control unit 4 controls the calibration module to move within the field of view of the detection module 2, and after the temperature calibration is completed, the position control unit 4 controls the calibration Control the module to move out of the field of view of the sensing module 2 to avoid blocking the measurement object. In addition, in a specific embodiment of the present invention, the position control unit 4 may perform the operation of moving the calibration module back and forth, moving up and down, or rotating the calibration module to meet various demands.

The temperature control unit is used to control the temperature of the blackbody radiation source 1 to reach a set temperature. When the black body radiation source 1 needs to reach a set temperature, the temperature control unit controls the black body radiation source 1 to raise the temperature to reach the set temperature. In a specific embodiment of the present invention, the temperature control unit may be integrated within the position control unit 4 , and may be located within the housing 5 of the infrared temperature measurement and monitoring system. The temperature control unit is connected to the data processing module 3 and is also used to transmit the set temperature of the blackbody radiation source 1 to the data processing module 3 .

Also, because the set temperature of the blackbody radiation source 1 may differ from the actual temperature of the blackbody radiation source 1 due to environmental influences and control errors, the calibration module is configured to detect the real-time temperature of the blackbody radiation source 1 further comprising a temperature detection unit for The module 3 may compensate the set temperature in real time according to the real-time temperature to improve the accuracy and precision of the calibration curve. Further, in this specific embodiment, the temperature detecting unit is a temperature sensor.

In the specific embodiment described above, the calibration module comprises one blackbody radiation source 1 , and in another specific embodiment of the present invention, the calibration module comprises a plurality of blackbody radiation sources 1 , and the detection module ( The distances of the plurality of blackbody radiation sources 1 from 2) are different.

Referring to Figure 4, it shows a schematic diagram of the cross-sectional structure of the infrared temperature measurement and monitoring system according to another specific embodiment of the present invention.

Accordingly, it is possible to calculate the attenuation effect of the background environment on the infrared radiation of the measurement object to match the attenuation coefficient for the infrared radiation of the background environment, and furthermore, it is possible to realize the calibration of the infrared temperature measurement system.

In addition, different preset temperatures can be applied to a plurality of blackbody radiation sources 1 as well, so as to realize simultaneous measurement for different positions, different temperature objects, acquire calibration data to form a calibration curve, and improve the accuracy of the measurement system can be further improved.

5 and 6 are schematic diagrams of the operating principle of an infrared temperature measurement and monitoring system according to a specific embodiment of the present invention.

Referring to FIG. 5 , when temperature calibration is required for the infrared temperature measurement and monitoring system, the calibration module (which may be the blackbody radiation source 1 ) is moved to a required position according to the command of the data processing module 3 .

At this time, the calibration module (or the blackbody radiation source 1 ) is in a retracted state, and the control module can move the calibration module closer to the housing 5 or to be hidden inside the housing 6 . Accordingly, the external volume of the housing 5 can be reduced, and at the same time, the housing 5 can be made more compact and beautiful. The image imaged by the correction module through the optical lens 21 is outside the detection range of the infrared detector 22, and does not affect the full frame measurement and control of the infrared temperature measurement and monitoring system. It is particularly suitable for use in special monitoring situations where the measurement object must not be obscured.

In addition, if real-time calibration is required, the calibration module (which may be the blackbody radiation source 1) can always be within the detection range of the infrared sensor to achieve real-time calibration of the infrared temperature measurement and monitoring system.
