[0029] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Combine the following Figure 1 and Figure 2 The utility model describes an infrared thermal imager calibration device.

[0031] like Figure 1 and Figure 2 As shown, the utility model provides an infrared thermal imager calibration device 1, comprising: a movable guide rail 11, a plurality of black body furnaces 12 and an infrared thermal imager carrier 13. A measuring position 111 is provided on the movable guide rail 11. The plurality of black body furnaces 12 are slidably arranged on the movable guide rail 11, wherein each black body furnace 12 is set to a different temperature. The infrared thermal imager carrier 13 is arranged on the side of the movable guide rail 11, and an installation position 131 corresponding to the measurement position 111 is arranged on the infrared thermal imager carrier 13, and the installation position 131 is used to set the infrared thermal imager; when any black body furnace 12 moves to the measurement position 111, the measuring lens of the infrared thermal imager installed on the installation position 131 is aimed at the black body furnace 12.

[0032] In this embodiment, the movable guide rail 11 and the infrared thermal imager carrier 13 are used to respectively set the blackbody furnace 12 and the infrared thermal imager to be calibrated. Specifically, an installation station 131 is provided on the infrared thermal imager carrier 13 to install and fix the infrared thermal imager to be calibrated. The shooting direction of the measuring lens of the infrared thermal imager installed on the installation station 131 points to the measuring position 111 on the movable guide rail 11. When the blackbody furnace 12 slides through the measuring position 111, the infrared thermal imager on the installation station 131 can measure the temperature of the blackbody furnace 12 for calibration. At the same time, by setting a plurality of blackbody furnaces 12 with different temperatures, these blackbody furnaces 12 pass through the measuring position 111 in turn along the movable guide rail 11, and the infrared thermal imager on the installation station 131 can be calibrated at multiple temperature points, which is convenient to operate and has high calibration efficiency. It is easy to understand that the number of blackbody furnaces 12 and the temperature of each blackbody furnace 12 can be reasonably designed according to the measurement range and accuracy standard of the infrared thermal imager with calibration.

[0033] The infrared thermal imager calibration device 1 of the utility model is provided with a movable guide rail 11 and an infrared thermal imager carrier 13. The infrared thermal imager carrier 13 is provided with an installation position 131 for installing the infrared thermal imager to be calibrated. The movable guide rail 11 is provided with a black body furnace 12 and a measuring position 111 corresponding to the measuring lens of the infrared thermal imager. When the black body furnace 12 passes through the measuring position 111, the infrared thermal imager on the installation position 131 can measure the temperature of the black body furnace 12 for calibration. At the same time, the user can set a plurality of black body furnaces 12 with different temperatures on the movable guide rail 11 according to the calibration requirements. When calibrating, the plurality of black body furnaces 12 are passed through the measuring position 111 in sequence along the movable guide rail 11, so that the infrared thermal imager on the installation station 131 can be calibrated at a plurality of temperature points. There is no need to manually hold the infrared thermal imager, nor is there a need to heat the black body furnace 12 to different temperatures for measurement, thus eliminating the intermediate heating time, making the operation convenient and the calibration efficiency high, which effectively solves the defect that the efficiency of manual calibration of infrared thermal imagers in the prior art is too low.

[0034] It is easy to understand that the movable guide rail 11 can be set on a stand.

[0035] The infrared thermal imager calibration device 1 of the present application can calibrate infrared thermal imagers including but not limited to online imagers, portable imagers, airborne imagers, etc. During the test, the ground where the device is placed should be flat, and there should be no strong vibration and strong electromagnetic interference around. The infrared thermal imager calibration device 1 should have a heat dissipation space of more than 20 cm from the wall in front and behind.

[0036] It is easy to understand that the infrared thermal imager calibration device 1 also includes a measurement and control host, which is in communication with the black body furnace 12 and the driving device of the movable guide rail 11 to control the temperature of the black body furnace 12 and control the movable guide rail 11 to drive the black body furnace 12 to slide through the measuring position 111. At the same time, the measurement and control host also includes a collection module, which is used to collect the temperature reading of the infrared thermal imager so as to draw the temperature measurement curve of the infrared thermal imager and perform subsequent calibration work.

[0037] Optionally, the acquisition module may be directly connected to the infrared thermal imager for communication to obtain the temperature reading; or, the acquisition module may directly identify the temperature reading on the display screen of the infrared thermal imager by visual recognition.

[0038] Optionally, in some embodiments, Figure 1 As shown, there are multiple installation stations 131, and the multiple installation stations 131 are arranged at intervals along the length direction of the movable guide rail 11.

[0039] In this embodiment, multiple installation stations 131 are provided so that multiple infrared thermal imagers can be provided on the infrared thermal imager carrier 13. It is understandable that the multiple installation stations 131 are arranged at intervals along the length direction of the movable guide rail 11, and the movable guide rail 11 also has multiple measurement positions 111 corresponding to the installation stations 131 one by one. Multiple black body furnaces 12 with different temperatures pass through these measurement positions 111 in turn, so that the temperature calibration of multiple infrared thermal imagers can be realized, which is convenient to operate and further improves the calibration efficiency.

[0040] Optionally, in some embodiments, a first slide rail parallel to the movable guide rail 11 is disposed on the infrared thermal imager stage 13 , a plurality of sliding members are slidably disposed on the first slide rail, and an installation station 131 is disposed on each sliding member.

[0041] In this embodiment, a first slide rail is provided on the infrared thermal imager carrier 13, and the installation stations 131 are provided on a plurality of sliding members on the first slide rail. The plurality of sliding members can slide along the first slide rail so that the calibration personnel can adjust the positions and spacings of the installation stations 131, and correspondingly adjust the positions of the measurement stations 111 corresponding to each installation station 131 and the spacings of the measurement stations 111, so that the spacings and positions of the measurement stations 111 meet the calibration requirements, with high flexibility, convenience and practicality.

[0042] It is understandable that the distance between adjacent installation stations 131 can be designed and adjusted according to the distance between adjacent black body furnaces 12 .

[0043] Optionally, in some embodiments, the distance between two adjacent black body furnaces 12 is equal to the distance between two adjacent installation stations 131 .

[0044] In this embodiment, by setting the distance between two adjacent installation stations 131 to be equal to the distance between two adjacent blackbody furnaces 12, the distance between two adjacent measuring positions 111 is made equal. When the blackbody furnace 12 slides along the movable guide rail 11, when the first blackbody furnace 12 moves to the second or subsequent measuring position 111, the subsequent blackbody furnaces 12 also move to the previous measuring position 111 in a one-to-one correspondence, which facilitates the temperature reading of the infrared thermal imager at different installation stations 131, reduces the number of times the movable guide rail 11 pauses, and improves the calibration efficiency.

[0045] In some embodiments, Figure 1 and Figure 2 As shown, the infrared thermal imager calibration device 1 further includes a first lifting platform 14. The first lifting platform 14 is slidably disposed on the movable guide rail 11, and the black body furnace 12 is disposed on the first lifting platform 14. The first lifting platform 14 can be raised and lowered to adjust the height of the black body furnace 12.

[0046] In this embodiment, by setting the blackbody furnace 12 on the first lifting platform 14, the first lifting platform 14 can adjust the height of the blackbody furnace 12. On the first hand, the first lifting platform 14 can adjust the height of the blackbody furnace 12 according to the position of the measuring lens of the infrared thermal imager, so that when the blackbody furnace 12 moves to the measuring position 111, the measuring lens of the infrared thermal imager can be aimed at the cavity center of the blackbody furnace 12, and the temperature measurement is more accurate, and it can be applicable to infrared thermal imagers of different models and sizes; on the second hand, the first lifting platform 14 and the movable guide rail 11 can adjust the position of the blackbody furnace 12, so that the measuring lens of the infrared thermal imager can be aimed at different areas of the same blackbody furnace 12 for temperature measurement, and the temperature measurement consistency of the infrared thermal imager can be calibrated, which is convenient and practical.

[0047] Preferably, when performing temperature measurement consistency calibration, it is best to set the distance between the blackbody furnace 12 and the installation station 131 to be equal, so that multiple blackbody furnaces 12 can be exactly located at the corresponding measurement position 111, so as to calibrate the infrared thermal imagers to be calibrated at multiple installation stations 131 at the same time.

[0048] In a specific embodiment, there are five black body furnaces 12 and ten installation stations 131. The spacing between the black body furnaces 12 is 45 cm; the spacing between the installation stations 131 is 45 cm. The five black body furnaces 12 can complete the temperature measurement consistency test for the infrared thermal imagers installed on the ten installation stations 131 in two times.

[0049] Specifically, the display screen of the calibrated infrared thermal imager can be equally divided into nine areas arranged in three rows and three columns, the center points of the nine areas are marked respectively, and the center point position is selected as the temperature measurement point to measure the temperature of the blackbody furnace 12.

[0050] During calibration, the measurement and control host controls the five blackbody furnaces 12 to adjust the temperature to 100°C. At the same time, the measurement and control host controls the movement of the movable guide rail 11 and the first lifting platform 14 to make the five blackbody furnaces 12 respectively align with the first five infrared thermal imagers to be tested; after the temperature of the blackbody furnace 12 stabilizes, the measurement and control host controls the movement of the movable guide rail 11 and the first lifting platform 14 to drive the blackbody furnace 12 to move, so that the center point of the blackbody furnace 12 is aligned with the center points of the nine regions in turn, thereby completing the temperature measurement consistency calibration of the first five infrared thermal imagers.

[0051] Next, the measurement and control host controls the movable guide rail 11 and the first lifting platform 14 to move to complete the temperature measurement consistency calibration of the last five infrared thermal imagers. The process is similar to the temperature measurement consistency calibration of the first five infrared thermal imagers and will not be repeated here.

[0052] Specifically, during the measurement, the infrared thermal imager emissivity parameter is set to 1, and the temperature of the marked points t is measured and recorded respectively. n , n=1,2,…,9; record 4 values ​​at each point and take the average value, which is used to calculate the indication error of the temperature measurement consistency of the calibrated infrared thermal imager. The calibration result should meet the requirements of the measurement standard, and its change should not exceed ±2℃. For infrared thermal imagers used for precise temperature measurement, its change should not exceed ±0.5℃.

[0053] Optionally, in some embodiments not shown, the infrared thermal imager calibration device 1 further includes a second lifting platform, which is disposed on the infrared thermal imager carrier 13 and is provided with an installation station 131 ; the second lifting platform can be raised and lowered to adjust the height of the installation station 131 .

[0054] In this embodiment, a second lifting platform is provided on the infrared thermal imager carrier 13 to adjust the height of the installation station 131, so as to adjust the relative height difference between the installation station 131 and the black body furnace 12, thereby adjusting the relative height difference between the infrared thermal imager installed on the installation station 131 and the black body furnace 12. It is understandable that the second lifting platform can also achieve similar functions and technical effects as the first lifting platform 14 in the above embodiment, which will not be described in detail here.

[0055] Optionally, in some embodiments not shown, a second slide rail parallel to the movable guide rail 11 is provided on the first lifting platform 14, and the black body furnace 12 can be slidably disposed on the second slide rail.

[0056] In this embodiment, by setting a second slide rail on the first lifting platform 14 and setting the blackbody furnace 12 on the second slide rail, the blackbody furnace 12 can slide along the second slide rail, so that the calibration personnel can adjust the position and spacing of each blackbody furnace 12, so that the spacing and position of the blackbody furnace 12 meet the calibration requirements, which is highly flexible, convenient and practical.

[0057] Optionally, in some embodiments, there are multiple first lifting platforms 14 , and the black body furnaces 12 are arranged on the first lifting platforms 14 in a one-to-one correspondence.

[0058] In this embodiment, a plurality of first lifting platforms 14 are provided, and each black body furnace 12 is respectively provided on a first lifting platform 14 so that the height of each black body furnace 12 can be independently adjusted, so that each black body furnace 12 can be independently adjusted according to the height of the measuring lens of the infrared thermal imager to be tested, so as to adapt to the calibration scenario in which the installation station 131 on the infrared thermal imager carrier 13 is installed with infrared thermal imagers of multiple models or sizes, with high flexibility and wider application scenarios.

[0059] Optionally, in some embodiments, there are multiple second lifting platforms, and the installation stations 131 are arranged on the second lifting platforms in a one-to-one correspondence.

[0060] In this embodiment, multiple second lifting platforms are set up, each of which is equipped with an installation station 131, so that the height of the infrared thermal imager installed on each installation station 131 can be independently adjusted to achieve functions and technical effects similar to those of the multiple first lifting platforms 14 in the above-mentioned embodiments, which will not be repeated here.

[0061] It is understandable that the number of black body furnaces 12 and installation stations 131 can be arbitrarily designed according to actual needs. It is easy to understand that when the number of black body furnaces 12 is less than the number of installation stations 131, when calibrating the temperature measurement consistency, the infrared thermal imagers on the installation stations 131 need to be calibrated in batches.

[0062] Optionally, in some embodiments, the number of black body furnaces 12 is greater than or equal to the number of installation stations 131 .

[0063] In this embodiment, by making the number of blackbody furnaces 12 greater than or equal to the number of installation stations 131, when calibrating the temperature measurement consistency, each installation station 131 is correspondingly provided with a blackbody furnace 12, so that the temperature measurement consistency of the infrared thermal imagers installed on all installation stations 131 can be calibrated at the same time, thereby improving the calibration efficiency.

[0064] Specifically, in some embodiments, the number of the black body furnaces 12 is greater than or equal to five.

[0065] In this embodiment, by setting more than or equal to five blackbody furnaces 12, the temperatures of each blackbody furnace 12 are different to provide sufficient calibration temperature points, and test calibration is performed on different temperature points within the entire measuring range of the infrared thermal imager. This is convenient and practical. Compared with using one blackbody furnace 12 to control the temperature to different temperatures for test calibration, it can save the time of intermediate heating and greatly improve the test efficiency.

[0066] Specifically, the calibration temperature points should be no less than five, and should include the upper and lower limits of the infrared thermal imager and the mid-range value. In a specific embodiment, the temperatures of the five black body furnaces 12 are controlled at 20°C, 50°C, 100°C, 150°C, and 200°C, respectively.

[0067] During calibration, the emissivity of the black body furnace 12 is set to 1.0. When the infrared thermal imager being calibrated is measuring, the standard temperature value t1 of the black body furnace 12 and the indicated value t2 of the infrared thermal imager being calibrated should be read after the temperature value of the black body furnace 12 is stable. The values ​​are recorded four times and the average value is taken to calculate the indicated value error. The temperature indicated value error calculation formula is:

[0068] When t1≤100℃, When t1>100℃,

[0069] Among them, Δθ1 is the temperature indication error expressed in absolute terms, and Δθ2 is the percentage temperature indication error expressed in relative terms.

[0070] Within the working measurement temperature range of the infrared thermal imager, the calibration result should meet the required measurement standard requirements. When the measured temperature t1≤100℃, the maximum allowable error shall not exceed ±2℃, expressed as absolute error; when the measured temperature t1>100℃, the maximum allowable error shall not exceed ±2%, expressed as relative error.

[0071] In some embodiments, Figure 1As shown, the infrared thermal imager calibration device 1 also includes a shooting module 15 and an image recognition unit (not shown in the figure). The shooting module 15 is arranged corresponding to the installation station 131, and the lens of the shooting module 15 is used to align the display side of the infrared thermal imager installed on the corresponding installation station 131; the shooting module 15 is connected to the image recognition unit for communication.

[0072] In this embodiment, by setting a shooting module 15 on the display side of the infrared thermal imager installed on the installation station 131, the shooting module 15 can capture the display image of the infrared thermal imager and transmit the display image signal to the image recognition unit. The image recognition unit can recognize the temperature reading on the infrared thermal imager according to the display image signal for calibration. There is no need to manually record the readings, and there is no need to connect the calibrated infrared thermal imager to the measurement and control host through wiring or wirelessly, which is easy to operate.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
