Among these, heating devices, as a common module in electronic products, are used in various fields. In particular, existing heat-not-burning (HNB) devices, as a new type of heating component, are widely used due to their high efficiency and rapid heating characteristics.

[0050] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0051] It should be understood that, when used in this application specification and the appended claims, the term "comprising" indicates the presence of the described features, integrals, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or a collection thereof.

[0052] Furthermore, in the description of this application and the appended claims, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0053] Please see Figure 1 , Figure 1 A schematic diagram of a temperature calibration system provided in an embodiment of this application is shown. See also... Figure 1 As shown, the temperature calibration system provided in this application embodiment includes: a temperature calibration device 11, multiple heated non-combustible (HNB) devices 12, and a temperature acquisition device 13. The temperature calibration device 11 is connected to the HNB devices 12 and the temperature acquisition device 13; the temperature probe 131 of the temperature acquisition device 13 is aligned with each of the HNB devices 12 to obtain the actual temperature value of each HNB device 12.

[0054] The temperature calibration device 11 can be configured with multiple interfaces, including wired communication interfaces. In this case, the HNB device 12 can be plugged into the wired communication interface of the temperature calibration device 11 via a USB data cable or other data cable to establish a communication connection with the temperature calibration device 11.

[0055] The HNB device 12 mentioned above can be a circumferential heating type HNB device or a center heating type HNB device.

[0056] In one possible implementation, the temperature calibration device 11 may also be equipped with a wireless communication module, such as a WiFi communication module or a Bluetooth communication module. The temperature calibration device 11 can transmit corresponding wireless communication signals through the wireless communication module. In this case, the HNB device can search for the aforementioned wireless communication signals and access the wireless local area network generated by the temperature calibration device 11, thereby establishing a communication connection with the temperature calibration device 11.

[0057] Similarly, the communication connection between the temperature acquisition device 13 and the temperature calibration device 11 can also be established by wired communication and wireless communication. The specific implementation process can be found in the above description and will not be repeated here.

[0058] In this embodiment, the temperature acquisition device 13 includes multiple temperature probes 131, each containing at least one temperature sensing element, which can be an infrared temperature sensing element, enabling infrared temperature measurement within a certain distance. Alternatively, the temperature sensing element can be a thermocouple. To obtain the actual temperature value of the HNB device 12, the temperature acquisition device 13 can align the temperature probes 131 with the HNB device 12. In some implementation scenarios, if the number of HNB devices 12 to be measured is greater than the number of temperature probes configured in the temperature acquisition device, the temperature acquisition device can control the temperature probes to move, aligning the probes with the HNB devices 12 whose heating time has reached the rated heating time, thereby achieving time-division multiplexing of different temperature probes.

[0059] by Figure 1 Taking this as an example, the temperature calibration system contains 128 HNB devices 12, namely HNB device 1 to HNB device 128. Correspondingly, the temperature acquisition device 13 is also equipped with a corresponding number of temperature probes 131, that is, it has 128 temperature probes 131. Each HNB device 12 is assigned an associated temperature probe 131 to obtain the actual temperature value of each HNB device 12.

[0060] Please see Figure 2 , Figure 2 The illustration shows a schematic diagram of a temperature calibration method provided in an embodiment of this application. The method includes the following steps:

[0061] In S201, when the detection conditions are met, the temperature calibration device sends a temperature rise command to the HNB device.

[0062] In this embodiment, when a preset detection condition is met, the temperature calibration device can send a heating command to the HNB device via a communication link. This heating command instructs the HNB device to heat the device to a preset standard temperature value. For example, if the HNB device and the temperature calibration device are connected via a serial port, the heating command is sent to the HNB device through the connected serial interface; if the HNB device and the temperature calibration device are connected via a wireless local area network (WLAN), the temperature calibration device can obtain the HNB device's address within the WLAN and generate a data packet carrying the aforementioned heating command based on that address, then send it to the HNB device via the WLAN. Optionally, if temperature calibration needs to be performed uniformly on all HNB devices within the WLAN, the heating command can be broadcast over the WLAN.

[0063] In this embodiment, the aforementioned detection condition can be a time-based condition. For example, the temperature calibration device may be configured with a corresponding calibration cycle, which is consistent with the temperature measurement cycle of a batch of HNB devices. For instance, when a batch of HNB devices is completed and a unified temperature measurement calibration process needs to be performed on the entire batch, all HNB devices can be connected to the temperature calibration device. In this case, when the preset calibration cycle is met, the temperature calibration device can execute operation S201. Of course, the temperature calibration device can also actively perform the calibration process based on the user's operation. The specific triggering method can be set according to requirements and is not limited here.

[0064] Furthermore, as another embodiment of this application, Figure 3 A flowchart illustrating a specific implementation of S201 according to an embodiment of this application is shown. Figure 2 Compared to the embodiments shown, Figure 3 In the illustrated embodiment, S201 specifically includes S2011 to S2013, which are described in detail below:

[0065] In S2011, if the temperature calibration device detects that the HNB device is connected to the temperature calibration device, it sends a start command to the HNB device.

[0066] In this embodiment, in addition to simultaneously performing temperature calibration on all HNB devices, the temperature calibration device can also perform a temperature calibration process on a new HNB device when it detects that a new HNB device has been connected. For example, if the temperature calibration device has multiple serial interfaces, and it detects that a certain serial interface has been connected by another device, it identifies the device type of that device. If the device type is an HNB device, it executes the operation in S2011. Alternatively, if an HNB device sends an access request to access the wireless network associated with the temperature calibration device, the temperature calibration device can send an access consent command to the HNB device and a start command at the same time.

[0067] In S2012, the HNB device responds to the start command, starts the HNB device, and after the start is completed, sends a start completion command back to the temperature calibration device.

[0068] In this embodiment, the HNB device can start the local device after receiving the start command. Since the HNB device may be in a power-off or standby state after leaving the factory, after being connected to the temperature calibration device, it can switch from the power-off or standby state to restart by receiving the start command sent by the temperature calibration device. After the start is completed, it can send a start-up completion command to the temperature calibration device.

[0069] In S2013, after receiving the start-up completion command, the temperature calibration device sends the temperature rise command to the HNB device.

[0070] In this embodiment, after determining that the HNB device has been started, the temperature calibration device can send a heating command to the HNB device to instruct the HNB device to heat the device to a preset standard temperature value.

[0071] In this embodiment of the application, when the temperature calibration device detects the HNB device being connected, it actively starts the HNB device and sends a heating command to it after the start-up is completed. This enables the temperature calibration process to be performed immediately upon connection, which can greatly improve the timeliness of the calibration process.

[0072] In S202, the HNB device responds to the heating command by heating the temperature to the standard temperature value.

[0073] In this embodiment, after receiving a heating command from the temperature calibration device, the HNB device can activate its built-in heating unit to heat the HNB device to a preset standard temperature value. Since the preset standard temperature value may be abnormal during the production of the HNB device, a calibration process is needed to determine whether the actual temperature value of the HNB device after heating is consistent with its corresponding standard temperature value. For example, the preset standard temperature value is 220℃, but due to a program error, the standard temperature value set in a certain HNB device is 180℃. In this case, when heating based on the temperature value recorded in the HNB device's built-in storage unit, the temperature will only reach 180℃, not 220℃. Therefore, a temperature calibration process is needed to identify and correct this abnormality.

[0074] In S203, the temperature acquisition device measures the actual temperature value of each of the HNB devices through a temperature probe and feeds back the actual temperature value to the temperature calibration device.

[0075] In this embodiment, the temperature acquisition device is equipped with a temperature probe. Since the temperature probe is aimed at the HNB device, it detects the actual temperature value of the HNB device. The temperature acquisition device can feed back the acquired actual temperature value to the temperature calibration device so that the temperature calibration device can determine whether the HNB device needs to be calibrated.

[0076] Furthermore, as another embodiment of this application, when the first number of temperature probes in the temperature acquisition device is less than the number of HNB devices that the calibration device can connect to, the temperature calibration system further includes an infrared image acquisition device; the infrared image acquisition device is connected to both the temperature acquisition device and the temperature calibration device. Please refer to [link to relevant documentation]. Figure 4 As shown, Figure 4 A schematic diagram of another temperature calibration system provided in this application. See also... Figure 4 As shown, there are 128 HNB devices connected to the temperature calibration device, and 120 temperature probes. Therefore, some HNB devices lack a aligned temperature probe. To optimize the allocation of temperature probes, an infrared image acquisition device is included in this embodiment. This device acquires infrared images of the HNB device to be measured. By analyzing the pixel values ​​of identical pixels in infrared images from different periods, it determines whether the HNB device has reached a stable temperature rise. If so, the corresponding temperature probe can be used for measurement. For HNB devices that have not reached a stable temperature rise, no temperature probe needs to be assigned, thus achieving dynamic allocation of temperature probes.

[0077] Figure 5 A flowchart illustrating a specific implementation of step S202 according to an embodiment of this application is shown. See also... Figure 5 As shown, with Figure 2 Compared to the illustrated embodiments, S203 in this application embodiment specifically includes S2031 to S2035, which are described in detail below:

[0078] In S2031, if the temperature calibration device detects that the second number of the actually connected HNB device is greater than the first number, it sends an image acquisition command to the infrared image acquisition device.

[0079] In this embodiment, the temperature calibration device can determine the second number of HNB devices that are currently connected. If the second number is greater than the first number of temperature probes, it indicates that there are not enough temperature probes. At this time, the temperature calibration device needs to activate the infrared image acquisition device and will send an image acquisition command to it.

[0080] In S2032, the infrared image acquisition device responds to the image acquisition command and acquires an infrared image of the HNB device to be measured at a preset acquisition cycle; the HNB device to be measured is an HNB device whose temperature probe is not aligned with the temperature acquisition device.

[0081] In this embodiment, after receiving an image acquisition command, the infrared image acquisition device can periodically acquire multiple infrared images according to a preset acquisition cycle. For example, if the acquisition cycle is 5 seconds, the infrared image acquisition device will acquire one infrared image every five seconds. The length of this acquisition cycle can be related to the heating time of the HNB device; the longer the heating time, the longer the corresponding acquisition cycle; conversely, the shorter the heating time, the shorter the corresponding acquisition cycle.

[0082] In this embodiment, the imaging window of the infrared image acquisition device is aimed at the HNB device that has not yet been assigned a temperature measuring probe. The captured infrared image records each HNB device to be assigned a temperature measuring probe. Therefore, based on the corresponding pixel area of ​​each HNB device to be assigned a temperature measuring probe in the infrared image, the associated pixel point can be determined, and based on the pixel value corresponding to the pixel point, the approximate temperature change of the HNB device can be determined. Optionally, the infrared image captured by the infrared image acquisition device records all HNB devices. Subsequently, based on the device position of each HNB device to be temperature measured, its corresponding pixel area in the infrared image can be determined.

[0083] In S2033, the infrared image acquisition device identifies pixels in the infrared image whose pixel change value is zero and whose duration is greater than a preset duration threshold as stable pixels based on the pixel change value of the corresponding pixel in the infrared image corresponding to each adjacent acquisition cycle.

[0084] In this embodiment, after acquiring an infrared image, the infrared image acquisition device compares the pixel change values ​​of the same pixels between two adjacent infrared images and detects whether there are any pixels whose pixel values ​​have not changed, i.e., pixels with a pixel change value of zero. Since the temperature of the HNB device continuously rises during the heating process, and the pixel value of each pixel in the infrared image represents the temperature value corresponding to that location, a unchanged pixel value indicates no temperature change. Therefore, before heating is complete, the pixel change values ​​of the pixels within the pixel area associated with the HNB device are not zero. If the pixel change value of the pixels within the pixel area associated with the HNB device is zero, it indicates that the HNB device in that area has completed heating. Therefore, the pixel change value can be used as a standard to identify whether the HNB device at a corresponding location has completed heating. Furthermore, to improve the accuracy of identification, a duration can be set; pixels whose temperature remains unchanged during this duration will be identified as stable pixels by the infrared image acquisition device.

[0085] In S2034, the infrared image acquisition device identifies the HNB device associated with the stable pixel as the target HNB device and feeds back the device position of the target HNB device to the temperature acquisition device.

[0086] In this embodiment, the infrared image acquisition device identifies the HNB device whose temperature is to be measured in the actual scene corresponding to the location of the stable pixel point, and identifies the HNB device corresponding to the stable pixel point as the target HNB device. At this time, the infrared image acquisition device can feed back the device location corresponding to the target HNB device to the temperature acquisition device so that the temperature acquisition device can allocate a temperature probe to the target HNB device.

[0087] In S2035, the temperature acquisition device, based on the device position fed back by the target HNB device, aligns the temperature probe with the target HNB device to obtain the actual temperature value of the HNB device.

[0088] In this embodiment, after receiving feedback from the infrared image acquisition module regarding the target HNB device, the temperature acquisition device can use an idle temperature probe to measure the target HNB device. If no idle temperature probe is available, the temperature probe corresponding to the calibrated HNB device can be used to measure the target HNB device after the calibrated HNB device is available.

[0089] In this embodiment, when the temperature probes of the temperature acquisition device are insufficient to measure all HNB devices, an infrared image acquisition device can acquire infrared images to identify HNB devices that have completed heating and assign temperature probes to them. The completion of heating is used as the priority for allocation, thereby improving the utilization rate of the temperature probes and reducing unnecessary waiting. On the other hand, when there are a large number of HNB devices, acquiring infrared images of all HNB devices with a single infrared image acquisition device allows for the simultaneous identification of multiple HNB devices that have completed heating, improving identification efficiency.

[0090] In S204, the temperature calibration device receives the actual temperature value of the HNB device fed back by the temperature acquisition device. If the actual temperature value of any HNB device does not match the standard temperature value, then the HNB device is calibrated.

[0091] In this embodiment, the temperature calibration device can receive the actual temperature value collected by the temperature acquisition device. This actual temperature value is the temperature reached by the HNB device after heating up in response to the heating command. Since factory requirements must be met, it is necessary to determine whether the actual temperature value of the HNB device matches the target temperature value (i.e., the standard temperature value). This matching includes ensuring the two temperature values ​​are equal, and also detecting whether the difference between them is within a preset fluctuation range. That is, the actual temperature value cannot be too low or too high, and can fluctuate around the standard temperature value. If the actual temperature value of the HNB device matches the standard temperature value, the HNB device is considered to have passed the heating test, and no calibration process is required.

[0092] In this embodiment, if the temperature calibration device detects that the actual temperature value of the HNB device does not match the standard temperature value, it means that the HNB device has not met the factory requirements. In this case, the HNB device needs to be calibrated.

[0093] In one possible implementation, the temperature calibration device can resend a temperature setting command to the HNB device, the temperature setting command carrying the aforementioned standard temperature value. In response to the temperature setting command, the HNB device resets the locally stored standard temperature value to achieve the calibration purpose.

[0094] Furthermore, as another embodiment of this application, Figure 6 A flowchart illustrating a specific implementation of S204 according to an embodiment of this application is shown. See also... Figure 6 As shown, with Figure 2 Compared to the illustrated embodiments, S204 in this application embodiment includes S2041 to S2045, which are described in detail below:

[0095] In S2041, the temperature calibration device calculates the temperature difference between the actual temperature value and the standard temperature value; and feeds back the temperature difference to any of the HNB devices.

[0096] In this embodiment, the temperature calibration device calculates the temperature difference between the actual temperature value and the standard temperature value, thereby determining the temperature rise deviation between the HNB device and the expected temperature rise target during the heating process. Since the temperature rise of the HNB device is related not only to the set temperature but also to the temperature value detected by its local temperature sensing element, if the temperature sensing element has a certain deviation, we need to appropriately increase or decrease the standard temperature value built into the HNB device according to the temperature rise deviation. For example, if the standard temperature value set for an HNB device is 220℃, and the HNB device temperature reaches 200℃, the detected temperature of the HNB device will be 220℃, indicating a temperature measurement deviation. In this case, the standard temperature value inside the HNB device needs to be set to 240℃. Then, when the temperature detected by the HNB device's temperature sensing element is 240℃, the corresponding actual temperature is 220℃, thus meeting the actual heating requirements.

[0097] In S2042, the HNB device receives the temperature difference value fed back by the temperature calibration device, and adjusts the target temperature value according to the temperature difference value so that when the HNB device heats up based on the target temperature value, the temperature is heated to the standard temperature value.

[0098] In this embodiment, after receiving the temperature difference value, the HNB device can adjust the locally stored target temperature value according to the temperature difference value. If the actual temperature value is lower than the standard temperature value, the target temperature value set in the HNB device can be increased; conversely, if the actual temperature value is higher than the standard temperature value, the target temperature value set in the HNB device can be decreased.

[0099] In S2043, the temperature calibration device sends a restart command to any of the HNB devices.

[0100] In this embodiment, after the temperature calibration device completes the recalibration of the HNB device, it needs to send a restart command to the HNB device to restart it, so that it can heat up at the adjusted target temperature value in subsequent operation.

[0101] In S2044, the HNB device responds to the restart command, restarts the HNB device, and after restarting, heats the HNB device to the standard temperature value based on the adjusted target temperature value.

[0102] In this embodiment, after receiving a restart command, the HNB device will restart the device. After restarting, in order to determine whether the HNB device can reach the preset standard temperature again, the HNB device will perform a heating operation again. At this time, the temperature acquisition device can collect the actual temperature value of the HNB device through the temperature probe and feed it back to the temperature calibration device, repeating the above steps.

[0103] In this embodiment of the application, by determining the temperature difference and calibrating the target temperature value of the HNB device, and restarting after calibration, the success rate of calibration can be improved, thereby improving the production and delivery efficiency of the HNB device.

[0104] It should be noted that the temperature calibration device is equipped with an indicator light on each interface connected to the HNB device. When the temperature calibration device detects that the actual temperature value of any HNB device does not match the standard temperature value, it will light up the indicator light associated with the interface connected to it, thereby prompting the user that the HNB device is in the calibration stage and cannot be shipped out, avoiding misoperation and improving the visibility of the calibration process.

[0105] Furthermore, following S2044, S2045 may also be included, as described in detail below:

[0106] In S2045, if the number of calibrations for any HNB device exceeds a preset threshold, the temperature verification device generates an anomaly report for that HNB device.

[0107] In this embodiment of the application, after completing a calibration operation of the HNB device, the temperature calibration device will record the number of calibrations of the HNB device. If the HNB device still fails to reach the preset standard temperature value after multiple repeated calibrations, the HNB device may be abnormal. At this time, an abnormality report of the HNB device will be generated to notify the user to handle it.

[0108] Further, please refer to Figure 7 As shown, Figure 7 A schematic diagram of the structure of a temperature calibration system according to another embodiment of this application is shown. See also Figure 7As shown, the temperature calibration system also includes a computer device. This computer device is connected to the temperature calibration unit. When the temperature calibration unit detects an abnormal HNB device (i.e., the actual temperature value does not match the standard temperature value), it sends an anomaly message about the HNB device to the computer. This anomaly message may carry the device identifier of the HNB device. The computer device has a monitoring interface that displays the status of all HNB devices undergoing temperature measurement, corresponding to a graphical control. Based on the color, markings, or annotations of the graphical control, the relevant information of the HNB device can be determined. Therefore, after receiving the anomaly message, the computer device extracts the device identifier carried in the anomaly message, thereby determining its associated graphical control in the monitoring interface and marking it as the corresponding anomaly status, so that the user can identify the HNB device currently undergoing calibration through the monitoring interface.

[0109] As can be seen from the above, the temperature calibration method provided in this application embodiment adds a corresponding temperature calibration device to the temperature calibration system. During the heating process of the HNB device, the actual temperature of the HNB device is measured by the temperature probe corresponding to the temperature acquisition device, and the actual temperature is fed back to the temperature calibration device. The temperature calibration device compares the actual temperature value of the HNB device with a preset standard temperature value to determine whether the HNB device can accurately heat up. If the actual temperature value does not match the standard temperature value, the HNB device is calibrated, thereby achieving the purpose of automatic calibration of HNB devices with abnormal heating. Compared with existing equipment management technologies, the temperature calibration system in this application embodiment does not require users to manually calibrate HNB devices with abnormal heating. It can automatically calibrate through the temperature calibration device during the heating detection process, which can greatly improve production efficiency and reduce the time cost required for calibration when producing HNB devices.

[0110] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
