Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0032] To address the technical problems in related technologies, this application provides a temperature module 50 calibration device, wherein the temperature module 50 includes a temperature measuring head 51 and a communication connector 52. (Reference) Figure 1 and Figure 2 The temperature module 50 calibration device includes:

[0033] The mounting bracket 10 is configured to fix the temperature module 50 and includes a vertically extending vertical plate 11; the vertical plate 11 includes a first side facing the temperature measuring head 51 after the temperature module 50 is fixed and an opposite second side.

[0034] The mounting bracket 10 also includes a clamping member (not shown in the figure) for clamping the temperature module 50, the clamping member being disposed on the first side; the vertical plate 11 also has a first through hole to allow the communication connector 52 to protrude to the second side.

[0035] A blackbody source 20 is disposed on the outside of the first side and has a target surface that matches the temperature measuring head 51; the target surface is set with a temperature according to calibration requirements.

[0036] The temperature calibration component 30 calibrates the temperature module 50 based on the set temperature of the target surface and the measured temperature obtained by the temperature measuring head 51 for calibration; the temperature calibration component 30 is located outside the second side and is communicatively connected to the communication connector 52.

[0037] Understandably, the temperature module 50 integrates electronic components such as sensors and signal conversion circuits, resembling a small circuit board. The mounting bracket 10 has a vertical plate 11 to facilitate the alignment of the temperature measuring head 51 with the blackbody source 20. That is, the temperature measuring head 51 and the target surface need to be aligned.

[0038] In the appendix Figure 1 In the middle, the first side is the right side of the vertical plate 11, and the second side is the left side of the vertical plate 11.

[0039] Specifically, the fixing frame 10 is also provided with a base plate 12, and the lower end of the vertical plate 11 is fixed on the base plate 12.

[0040] Specifically, the clamping element can be a clamp with a certain degree of elasticity, so that it can both clamp and reduce damage to the temperature module 50.

[0041] Understandably, the communication connector 52 can transmit the tested temperature to the temperature calibration component 30 via the communication cable, and the temperature calibration component 30 can also calibrate the blackbody source 20 via the communication connector 52. The communication connector 52 extends to the second side for easier communication connection with the temperature calibration component 30.

[0042] Specifically, the communication connector 52 can be a serial port connector, such as an RS-485 / 422 connector.

[0043] Specifically, the temperature calibration element 30 can be a smart device with accompanying calibration software.

[0044] The temperature module 50 calibration device of this application embodiment includes a fixing frame 10 to fix the temperature module 50, and a blackbody source 20 is set on one side of the fixing frame 10 for calibration by using the stable temperature of the blackbody source 20. This can improve the temperature measurement stability of the temperature module 50 in the same batch or different batches, and has a simple structure and low cost.

[0045] In some other embodiments of this application, the target surface includes a first target surface 221 and a second target surface 222 distributed vertically, wherein the first target surface 221 and the second target surface 222 are set at different temperatures.

[0046] In this way, the calibration of temperature module 50 can be made more scientific and accurate by setting two different temperatures.

[0047] In some other embodiments of this application, the bottom end of the blackbody source 20 is provided with a lifting mechanism (not shown in the figure) to switch the first target surface 221 and the second target surface 222 to match the temperature module 50.

[0048] Since the first target surface 221 and the second target surface 222 are distributed vertically, the height of the first target surface 221 or the second target surface 222 needs to be adjusted in order to align with the temperature measuring head 51 of the temperature module 50.

[0049] Specifically, the lifting mechanism can be a lead screw or similar device, and the drive can be manual or electric.

[0050] In some other embodiments of this application, the blackbody source 20 includes a housing 21 and a target 22, wherein the target surface is a portion of the sidewall of the target 22 that extends through the housing 21 toward the fixing frame 10 and protrudes from the housing 21.

[0051] The housing 21 protects the target 22 and improves its operational stability. The target 22 protrudes from the housing 21, facilitating temperature acquisition by the temperature module 50.

[0052] In some other embodiments of this application, the outer surface of the target surface is corrugated.

[0053] This allows the target to generate thermal radiation in different directions, making the heat received by the temperature measuring head 51 of the temperature module 50 more uniform, reducing the slight error in the heating of the target 22, and further improving the accuracy of calibration.

[0054] In some other embodiments of this application, the target 22 is made of copper.

[0055] Copper has excellent thermal conductivity, which further improves the uniformity of the blackbody surface temperature and the accuracy of the calibration.

[0056] In some other embodiments of this application, the target surface is coated with a graphene infrared radiation coating.

[0057] It can increase the emissivity of infrared radiation, for example, it can increase the emissivity to over 90%.

[0058] In some other embodiments of this application, the communication connector 52 is fixed in the first through hole via a hole-shaft fit, and the gap between the inner wall of the first through hole and the outer wall of the communication connector 52 is less than 0.1 mm. Specifically, the hole in the hole-shaft fit can be a square hole.

[0059] In this way, the communication connector 52 can be stably fixed in the first through hole without the need for other fasteners.

[0060] In some other embodiments of this application, the vertical plate 11 is made of bakelite.

[0061] Bakelite possesses sufficient strength, hardness, and toughness to provide stable support, as well as excellent electrical insulation properties to protect the electrical components in the temperature module 50.

[0062] In some other embodiments of this application, the temperature calibration component 30 is a computer with temperature calibration software installed.

[0063] Understandably, computers have good compatibility, can install many communication connectors, and can accommodate many calibration software programs for receiving information and controlling other devices.

[0064] The computer connects to the communication connector 52 of the temperature module 50 via a serial port cable 31 to receive temperature information and control the temperature module 50. Understandably, controlling the temperature module 50 includes calibrating the temperature module 50.

[0065] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations of the technical solutions contained in this application. Various modifications and changes can be made to the above embodiments without departing from the scope of this application. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this application that may not be explicitly described. Therefore, the above embodiments merely illustrate several implementations of this application and do not limit the scope of protection of this patent application.
