Description

[0002] Currently, blackbodies are mainly used in temperature measurement, and the main products related to blackbodies include blackbody furnaces. For example, blackbodies can be used for the calibration and verification of radiation thermometers. For instance, when calibrating a device under test using a comparative method, the temperature reproduced by the device under test needs to be compared with the temperature reproduced by a blackbody radiation source to determine whether the device under test is qualified. This requires the blackbody radiation source to reproduce a relatively accurate temperature and also to be able to determine the function of the device under test.

[0003] However, in reality, the blackbody in the relevant technology is an idealized object. In calibration and verification scenarios with high precision requirements, the temperature reproduced by the blackbody radiation source may be distorted. Summary of the Invention

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0042] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0043] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0044] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0045] A blackbody is an idealized object that absorbs all incoming electromagnetic radiation without any reflection or transmission. In other words, a blackbody has an absorption coefficient of 1 and a transmission coefficient of 0 for any wavelength of electromagnetic radiation. Physicists use it as the standard object for studying thermal radiation. An object that completely absorbs all incoming electromagnetic radiation without any reflection or transmission is called an absolute blackbody, or simply a blackbody.

[0046] However, almost none of the real objects in nature are blackbodies. The radiation emitted by any real object depends not only on the wavelength of the radiation and the object's temperature, but also on factors such as the type of material used, the manufacturing method, the thermal process, the surface condition, and environmental conditions. Therefore, to make the blackbody radiation law applicable to all real objects, a proportionality coefficient related to material properties and surface condition, namely emissivity, must be introduced. This coefficient represents the degree to which the thermal radiation of a real object approximates blackbody radiation, and its value is between zero and less than 1. According to the radiation law, once the emissivity of a material is known, the infrared radiation characteristics of any object are known. The main factors affecting emissivity are: material type, surface roughness, physicochemical structure, and material thickness. Furthermore, during the heating process of a blackbody, factors affecting emissivity may also be affected by conditions such as temperature and heating rate, leading to a certain degree of change in the emissivity during the heating process, and also presenting problems such as measurement difficulties. In view of this, this application proposes a method for correcting the radiation temperature error of a high-temperature blackbody radiation source, specifically for a surface-source blackbody.

[0047] The radiation temperature error correction method for high-temperature blackbody radiation sources described in this specification applies to surface blackbody sources, such as... Figure 1 As shown, it includes: a substrate 5, a second radiating layer 3 attached to one side of the substrate 5, and a first radiating layer 1 attached to the side of the second radiating layer 3 facing away from the substrate 5. In an optional embodiment of this specification, the substrate 5 may be a thermosetting adhesive, and this specification does not impose specific limitations on the thickness of the substrate 5.

[0048] The first radiating layer 1 comprises a plurality of first radiating units arranged sequentially along the second radiating layer 3. The second radiating layer 3 comprises a plurality of second radiating units arranged sequentially on the substrate 5. Optionally, each first radiating unit is a carbon nanotube, and each second radiating unit is a carbon nanotube. The dimension of the first radiating unit in its extension direction is larger than the dimension of the second radiating unit in its extension direction. Figure 1 The textures on the first radiating layer 1 and the second radiating layer 3 shown can be considered as the extension direction of the carbon nanotubes. The first radiating layer 1 may also include a substrate (optionally, the substrate is a material with high light transmittance, such as glass). The first radiating units are grown on the substrate. Then, the first radiating layer 1, containing the substrate and the first radiating units, is coated onto the second radiating layer 3, thus achieving the connection between the first radiating layer 1 and the second radiating layer 3. In this specification, the extension direction of the carbon nanotubes is the axial direction of the carbon nanotubes.

[0049] In an optional embodiment of this specification, the extension direction of the first radiating unit included in the surface-source blackbody is not parallel to the normal direction of the second radiating layer 3. This design, on the one hand, can reduce the impact of the uneven growth of carbon nanotubes on the surface smoothness of the first radiating layer 1 on the emissivity of the surface-source blackbody; on the other hand, it also helps to increase the distribution density of carbon nanotubes along the normal direction of the second radiating layer 3, which is beneficial to improving radiation efficiency. The term "parallel" in this specification means "generally parallel, with most of the carbon nanotubes extending in parallel directions," rather than an absolute concept. In reality, absolute parallelism is almost impossible to achieve.

[0050] In another optional embodiment of this specification, the extension direction of the second radiating unit included in the surface-source blackbody is parallel to the normal direction of the substrate 5. This design, on the one hand, avoids the carbon nanotubes themselves from blocking the electromagnetic waves emitted by the second radiating unit, and on the other hand, simplifies the molding process.

[0051] It should be noted that the extension directions of the first and second radiating units mentioned in this specification are their general, macroscopic extension directions. In actual production, carbon nanotubes may not have strictly uniform growth directions, and this phenomenon is also within the scope of the technical solutions described in this specification.

[0052] To further improve the uniformity of radiation from the surface-source blackbody, in a further optional embodiment of this specification, the first radiation layer 1 includes a first sub-layer 11 and a second sub-layer 13 arranged side-by-side on the second radiation layer 3; the extension directions of the first radiation units included in the first sub-layer 11 and the second sub-layer 13 are not parallel. Specifically, the radiation units on the first sub-layer 11 and the second sub-layer 13 all extend upwards at an angle towards the center of the surface-source blackbody. In this embodiment, the first sub-layer 11 and the second sub-layer 13 can be formed separately, and then spliced ​​onto the second radiation layer 3. This embodiment can at least ensure that the temperature in the middle part of the surface-source blackbody is uniform, and when applied to high-temperature scenarios, it can also ensure that the middle part of the surface-source blackbody has a high heating rate.

[0053] Furthermore, the blackbody in this specification also includes a first electrode connected to the first radiating layer 1 and a second electrode connected to the second radiating layer 3. The first electrode is used to control the radiation of the first radiating layer 1, and the second electrode is used to control the radiation of the second radiating layer 3. The overall radiation of the blackbody is formed by the superposition of the first radiating layer 1 and the second radiating layer 3. Optionally, both the first electrode and the second electrode control their respective radiating layers by adjusting the voltage.

[0054] The surface blackbody and error correction module in this specification together constitute the radiation temperature error correction system of the high-temperature blackbody radiation source. The error correction module is connected to the surface blackbody, and the methods in this specification are executed by the error correction module. Figure 2 As shown, the steps for error correction implemented by the error correction module will now be explained:

[0055] S200: Upon triggering a heating command, obtain the current temperature of the surface source blackbody and the target temperature to be reached as indicated by the heating command.

[0056] The current temperature in this step is the temperature of the surface source blackbody at the current moment. If the method in this specification was also triggered by the previous heating command, the current temperature is the temperature obtained after the previous heating and the "updated" temperature mentioned later in this specification.

[0057] In practical applications of surface-source blackbodies, users may need to adjust the temperature of the blackbodies based on their usage requirements. In such cases, a temperature increase command can be generated based on the user's temperature adjustment operation. The temperature increase command in this manual can be a string of characters, and its function includes at least a temperature increase indication and the target temperature that the surface-source blackbodies should reach (i.e., the target temperature).

[0058] S202: Find a heating strategy that matches both the current temperature and the target temperature from the preset heating strategy library, and use it as the target strategy.

[0059] The heating strategy library in this manual is based on a pre-set database of human experience. Since the surface source blackbody structure in this manual is fixed, technicians can construct the heating strategy library based on the temperature accuracy requirements of the applicable scenarios of the surface source blackbody through calculation and experimentation.

[0060] The heating strategy library can be a database containing rows and columns, representing the correspondence between elements in those rows and columns, such as a table. The heating strategy records in this specification record the correspondence between the current temperature range (e.g., the current temperature range as rows), the target temperature range (e.g., the target temperature range as columns), the first electrode control method, and the second electrode control method (e.g., as elements). Techniques based on tables used in related technologies are applicable to this specification.

[0061] The electrode (including the first electrode and the second electrode) control method indicates, on the one hand, the amount of voltage increase of the corresponding electrode; on the other hand, it also indicates the timing of the voltage increase of the electrode (for example, the second electrode starts to increase voltage 10ms after the first electrode starts to increase voltage).

[0062] In practical applications, if the search results are not unique, the result with the largest electrode voltage change represented by the first electrode control method will be used as the target strategy. The first electrode is the most sensitive to the control of the surface source blackbody, and this embodiment improves the heating efficiency of the surface source blackbody.

[0063] S204: The increase in the first electrode voltage obtained based on the first electrode control method, the increase in the second electrode voltage obtained based on the second electrode control method, and the increase in the target temperature relative to the current temperature are used as available parameters.

[0064] S206: Execute the target strategy, and after the temperature of the surface source blackbody no longer continues to rise, update the current temperature of the surface source blackbody.

[0065] The method of executing the target strategy is to control the first and second electrodes according to the electrode control method expressed by the target strategy, so as to achieve the heating of the surface source blackbody.

[0066] The phrase "the temperature of the blackbody no longer continues to rise" in this specification means that the blackbody has theoretically reached the target temperature, but in reality, there may be a certain deviation from the target temperature, and the temperature of the blackbody may fluctuate due to various factors such as the environment. The criteria for determining that the blackbody temperature no longer continues to rise can be: after a specified time (a preset value, which can be obtained empirically) following the completion of the target strategy, the blackbody is considered to have stopped heating. Alternatively, after a specified time following the completion of the target strategy, if no voltage fluctuation of the first or second electrode greater than the fluctuation threshold (a preset value, which can be obtained empirically) can be detected, the blackbody is considered to have stopped heating.

[0067] The update in this step indicates that, based on the execution of the target strategy, the temperature of the blackbody has essentially approached the target temperature. Ideally, if the blackbody is a perfect blackbody, the electrode control does not incur additional charge loss, and other factors affecting the blackbody's radiation are ignored, then the updated current temperature is the target temperature. However, reality is not ideal. In such cases, the updated current temperature (i.e., the target temperature) often differs somewhat from the actual temperature.

[0068] In an optional embodiment of this specification, the radiation temperature error correction of the high-temperature blackbody radiation source further includes a display module. The display module is used to display the current temperature and / or the target temperature. The result of the correction obtained through this specification (i.e., the actual temperature) can also be displayed on the display module.

[0069] S208: Using the available parameters, correct the current temperature of the surface source blackbody after the update.

[0070] Absolute blackbodies do not exist in nature. The calibration and verification of temperature measurement products such as radiation thermometers based on blackbody radiation sources are mostly performed under the assumption that the blackbody radiation source used during testing is an absolute blackbody. This leads to distortions in the calibration and verification results due to the influence of the blackbody radiation source. Furthermore, in some calibration and verification scenarios, the emissivity of the blackbody radiation source is used as the basis for determining the calibration and verification results. However, in high-precision, continuous temperature measurement scenarios, the temperature of the blackbody radiation source needs to rise to a certain value, and the emissivity of the blackbody radiation source may change, thus affecting the accuracy of the calibration and verification results. In view of this, this application provides a surface-source blackbody. Based on the structural design of the surface-source blackbody, it achieves the technical effects of relatively stable emissivity and high radiation efficiency. Furthermore, for the surface blackbody provided in this application, a method for correcting the radiation temperature error of a high-temperature blackbody radiation source is proposed. Even if the emissivity of the surface blackbody deviates from the ideal value or fluctuates, the method described in this specification can correct the error between the actual temperature of the surface blackbody and the target temperature, allowing the user to know the specific actual temperature of the surface blackbody. Therefore, when using the method described in this specification to apply the surface blackbody to the calibration and verification of temperature measurement products, it helps to improve the accuracy of the results obtained.

[0071] In a further optional embodiment of this specification, the target temperature range for which the method described herein is applicable is 900 degrees Celsius to 1200 degrees Celsius.

[0072] This specification describes, in one embodiment, how corrections are made based on available parameters. Specifically, the updated current temperature of the surface source blackbody is corrected using the following formula (a):

[0073]

[0074] In the formula, t f This is the result obtained through correction; t s It is the current temperature of the surface source blackbody after the update; e is the natural exponent; Δu max It is the absolute value of the larger of the first electrode voltage increase and the second electrode voltage increase; Δu min It is the absolute value of the smaller of the first electrode voltage increase and the second electrode voltage increase; Δt is the temperature increase of the target temperature compared to the current temperature before the update; |Δu 0 | is the absolute value of the larger of the increases in voltage at the first electrode and the increases in voltage at the second electrode. The voltage is measured in volts, and the temperature in millidegrees Celsius.

[0075] The blackbody in this specification comprises two radiating layers: a first radiating layer 1 and a second radiating layer 3. These two radiating layers are interconnected and not independent. Voltage control of one radiating layer will cause slight changes in the adjacent radiating layer, potentially affecting the overall emissivity of the blackbody. The correction for the current temperature of the blackbody in this application, achieved through this formula, combines the voltage increase of the first electrode, the voltage increase of the second electrode, and the difference between the current temperature and the target temperature before implementing the target strategy. This results in a more accurate correction and better reflects the actual situation of the blackbody in this application.

[0076] In a further optional embodiment of this specification, in addition to using available parameters for correction, the duration of the heating process is also considered in correcting the updated current temperature. In this embodiment, the time taken from the execution of the target strategy until the temperature of the blackbody stops increasing is first determined. Then, the updated current temperature of the blackbody is corrected using the available parameters and the duration. Afterwards, the updated current temperature is corrected using the following formula (ii).

[0077]

[0078] In the formula, L is the time taken from the execution of the target strategy until the temperature of the surface source blackbody stops rising. The unit of time is milliseconds.

[0079] The heating time reflects the influence of the blackbody's structure on temperature uniformity. This temperature uniformity may cause slight temperature differences in different regions of the blackbody. Incorporating this difference into the correction calculation can, to some extent, overcome the errors caused by the blackbody's structure.

[0080] It is understood that the radiation temperature error correction system of the high-temperature blackbody radiation source described above can realize each step of the radiation temperature error correction method of the high-temperature blackbody radiation source provided in the foregoing embodiments. The radiation temperature error correction system of the high-temperature blackbody radiation source will not be described in detail here.
