Description

Technical Field

[0001] This invention relates to the field of temperature calibration technology, and in particular to a temperature calibration system for heating equipment and a temperature calibration method thereof. Background Technology

[0002] For heating equipment with heating functions, the temperature of the heating element needs to be controlled. Existing temperature control technologies for the heating element in heating equipment require a temperature detection unit to collect the temperature of the heating element. The control unit then calculates the heating element temperature based on the feedback signal from the temperature detection unit, compares the calculated temperature with the set temperature, and controls the calculated temperature parameters of the heating element based on the comparison result, thereby achieving temperature control. However, in practical applications, due to factors such as temperature transfer between the temperature detection unit and the heating equipment, the accuracy of temperature control can vary between different manufactured heating equipment. For example, when the set heating temperature is 200℃, some heating equipment may not reach 200℃, while others may exceed 200℃. Therefore, providing a heating equipment temperature calibration system to avoid temperature errors caused by factors such as contact conduction, improving the accuracy of temperature control in heating equipment, and ensuring that the actual temperature of the heating element matches the set temperature is a technical problem that urgently needs to be solved by those skilled in the art.

The control host acquires a first temperature value from the heating device under test on the calibration tray through the non-contact temperature measuring device and sends the first temperature value to the heating device under test. This causes the heating device under test to adjust its heating element temperature calculation parameters according to the first temperature value, ensuring that the second temperature value calculated based on the temperature calculation parameters is the same as the first temperature value. This achieves consistency between the actual temperature of the heating element and the set temperature of the heating equipment while avoiding temperature errors caused by contact conduction.

[0063] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0064] For easier understanding, please refer to Figure 1 and Figure 2 The present invention provides an embodiment of a temperature calibration system for heating equipment, including a non-contact temperature measuring device, a control host, a calibration platform, a heating equipment to be tested, and a human-machine interface;

[0065] The calibration stand is equipped with a connection point and a calibration tray for fixing the heating device under test. A connecting wire is configured on the calibration tray. One end of the connecting wire is connected to the heating device under test, and the other end of the connecting wire is connected to the connection point.

[0066] The control host is connected to the connection point on the calibration platform via a serial port;

[0067] The non-contact temperature measurement device and the human-machine interface are respectively connected to the control host.

[0068] The non-contact temperature measuring device is used to collect the temperature value of the heating device under test on the calibration tray;

[0069] The control host is used for:

[0070] The first temperature value of the heating device under test is collected by the non-contact temperature measuring device when the heating element of the heating device under test is heated to a set temperature. The first temperature value is sent to the heating device under test. The first temperature value is the highest temperature value of the heating device under test collected by the non-contact temperature measuring device.

[0071] The heating device under test is used to adjust the temperature calculation parameters of the heating element of the heating device under test according to the first temperature value, so that the second temperature value calculated by the heating element according to the temperature calculation parameters is the same as the first temperature value.

[0072] The human-machine interface is connected to the control host;

[0073] The human-computer interaction interface is used for:

[0074] The display shows the temperature measurement information of the non-contact temperature measurement device, which includes at least one of the following: thermal imaging image, temperature measurement area, temperature measurement status, and temperature.

[0075] It should be noted that, in this embodiment of the invention, the calibration platform is provided with the calibration tray, which is used to fix one or more of the heating devices under test. The calibration tray is provided with connecting wires, and multiple connecting wires can be provided, the number of which is the same as the number of heating devices under test fixed on the calibration tray. One end of each connecting wire is connected to the heating device under test, and the other end is connected to a connection contact point on the calibration platform. The control host is connected to the connection contact point on the calibration platform via a serial port. The number of serial ports is the same as the number of connecting wires, and multiple serial ports are connected to the connection contact point on the calibration platform. Therefore, after the heating devices under test are fixed on the calibration tray, each heating device under test can be connected to the control host via the connection contact point.

[0076] The non-contact temperature measurement device can be an infrared thermometer, which is connected to the control host (PC) via RJ45 (TCPIP) network port communication protocol to provide temperature information and image information of each point in the temperature measurement area in real time.

[0077] The working principle of the heating equipment temperature calibration system in this embodiment of the invention is as follows:

[0078] After the heating device under test is fixed to the calibration platform and the corresponding wiring is completed, the control host sends a command to the heating device under test, causing the heating device to control the heating element to heat to the set temperature. When the heating element reaches the set temperature, the control host controls the non-contact temperature measuring device to collect the temperature of the heating device under test on the calibration tray. The highest temperature value of the heating device under test collected by the non-contact temperature measuring device is recorded as the first temperature value. The temperature collected by the non-contact temperature measuring device is fed back to the heating device under test. The heating device under test determines whether to adjust the temperature calculation parameters of the heating element based on the comparison between the first temperature value and the second temperature value calculated by the heating element according to the temperature calculation parameters. If the first temperature value and the second temperature value are inconsistent, the heating device under test adjusts the temperature calculation parameters of the heating element so that the second temperature value calculated by the heating element according to the temperature calculation parameters is the same as the first temperature value. When the first temperature value and the second temperature value are consistent, the temperature calibration of the heating device under test is completed. After calibration, the heating device under test adjusts the temperature of the heating element to the set temperature.

[0079] The calibration platform can also be equipped with LED lights. When temperature calibration begins, the LED lights will illuminate to indicate that temperature calibration is in progress. When temperature calibration ends, the LED lights will turn off to indicate that the temperature calibration work has been completed.

[0080] As a further improvement, in one embodiment, the heating device temperature calibration system has two or more connecting lines, with one end of each connecting line connected to a heating device under test and the other end connected to the connecting contact point.

[0081] The control host is also used for:

[0082] According to the shape or size of the heating device under test, the calibration tray is divided into multiple temperature measurement areas, and each temperature measurement area corresponds to one of the heating devices under test;

[0083] The control host is connected to the connection contacts on the calibration platform through multiple serial ports. Each serial port is used to transmit information of the heating device under test within a temperature measurement area.

[0084] The human-computer interaction interface is specifically used for:

[0085] Displays the temperature measurement information of the non-contact temperature measuring device corresponding to each temperature measuring area.

[0086] It should be noted that, based on the shape or size of the heating device under test, the calibration tray is divided into multiple temperature measurement areas, each corresponding to one heating device under test, such as... Figure 2 As shown, Figure 2 In this system, based on the shape or size of the heating device under test, the calibration tray is divided into 10 temperature measurement areas (2×5, i.e., 2 rows and 5 columns), numbered 1 to 10. The temperature measurement information displayed on the human-machine interface includes a thermal imaging image and / or a thermal imaging data table corresponding to each temperature measurement area. The thermal imaging data table includes the temperature measurement area, measurement status, and / or temperature. The thermal imaging data table may also include the measurement time, used to record and display the time (in seconds) taken for the heating device under test to begin temperature calibration. Therefore, the heating device temperature calibration system can fix multiple heating devices under test on the calibration tray at once and perform temperature calibration sequentially, improving efficiency.

[0087] As a further improvement, in one embodiment, the control host of the heating equipment temperature calibration system is also used for:

[0088] Batch temperature calibration is performed on multiple heating devices under test on the calibration tray;

[0089] The batch temperature calibration includes:

[0090] The control host acquires the first temperature value of the heating device under test in each temperature measurement area on the calibration tray through the non-contact temperature measuring device, and sends the first temperature value of the heating device under test to the corresponding heating device under test;

[0091] Each of the heating devices under test adjusts the temperature calculation parameters of the heating element according to the corresponding first temperature value, so that the second temperature value calculated by the heating element according to the temperature calculation parameters is the same as the first temperature value.

[0092] The human-machine interface is also used to display a batch temperature calibration control interface, which includes a batch temperature calibration start button and optional heating devices to be tested for batch temperature calibration.

[0093] It should be noted that multiple heating devices under test can be simultaneously fixed on the calibration tray and their wiring connected. The heating elements of all the heating devices under test on the calibration tray are heated to a set temperature. Then, the non-contact temperature measuring device collects the first temperature value of all the heating devices under test on the calibration tray according to the temperature measurement area. The first temperature value is sent to the corresponding heating device under test, causing the heating device under test to adjust the temperature calculation parameters of its heating element based on the first temperature value, so that the second temperature value calculated by the heating element based on the temperature calculation parameters is the same as the first temperature value. Therefore, the heating device temperature calibration system can simultaneously perform batch temperature calibration of multiple heating devices under test, further improving temperature calibration efficiency.

[0094] When displaying the thermal imaging images of all the non-contact temperature measurement devices, the human-computer interaction interface separates each thermal imaging image using dividing lines, such as... Figure 2 As shown, the temperature measurement area number is displayed on each thermal imaging frame (e.g., Figure 2 The top left corner of each temperature measurement area (1-10), and the temperature measurement status (e.g., ... Figure 2 The "idle" status displayed in each temperature measurement area) and / or temperature value (e.g., Figure 2 Each temperature measurement area is displayed with "030" and "031", where "030" and "031" represent temperatures of 31℃ and 30℃ respectively. The location of the first temperature value on each thermal imaging frame is also marked (e.g., ...). Figure 2 (The cross-shaped label for each temperature measurement area).

[0095] As a further improvement, in one embodiment, the control host is also used for:

[0096] Configure the administrator configuration interface, which includes a serial port configuration interface for configuring serial port allocation information, a temperature parameter configuration interface for configuring temperature measurement data of the non-contact temperature measuring device, and / or a communication parameter interface for configuring communication parameter information.

[0097] The human-computer interaction interface is also used to display the administrator configuration interface.

[0098] It should be noted that, as Figures 4 to 6 As shown, Figure 4 The serial port configuration interface specifies the number of serial ports corresponding to the number of temperature measurement areas. If there are 10 temperature measurement areas, there are 10 serial ports. Figure 5This is the infrared configuration interface for non-contact temperature measurement devices, specifically infrared thermometers. The interface includes settings such as temperature unit, temperature range (infrared thermometers have two temperature ranges: one is -20 to 80°C, where temperatures above 80°C are considered 80°C; this range is more accurate but narrower; the other is -20 to 600°C, which is less accurate but has a wider range; the choice depends on the application), emissivity, transmittance, focal length, frames per second, etc. Specific parameter configuration options can be set according to the actual situation. Figure 6 The communication parameter interface includes baud rate, parity bit, data bits, stop bits, calibration interval, etc. Specific parameter configuration options can be set according to the actual situation.

[0099] like Figure 8 As shown, the administrator configuration interface also includes a temperature information display configuration interface;

[0100] The temperature measurement information display configuration interface is used to configure whether to display split lines in the thermal imaging image (e.g., ...). Figure 8 The options for displaying partition lines and whether to display the highest temperature are available (e.g., check the box). Figure 8 The options for displaying the highest temperature (checkable) and the location of displaying the highest temperature value (e.g., [option name]) are available. Figure 8 The options for displaying the highest temperature point (checkable) and displaying the temperature measurement area number (e.g., [option name]) are available. Figure 8 The option to display partition numbers can be checked) and / or the font size option in the thermal imaging image (such as...). Figure 8 The text includes options for font size within the image (e.g., font size options for thermal imaging data tables). Figure 8 (Table font is optional);

[0101] The human-computer interaction interface is also used to display the temperature measurement information display configuration interface.

[0102] The heating equipment temperature calibration system can also be equipped with a voice output device, which is connected to the control host. Additionally, the administrator configuration interface includes a voice configuration interface, as shown below. Figure 8 As shown. The voice configuration interface is used to configure whether to provide voice prompts when starting to connect to the non-contact temperature measurement device (e.g., ...). Figure 8 The options include: "Start connecting to infrared device (check the box)" and "Whether to provide voice prompts when non-contact temperature measurement devices malfunction (e.g., ...)". Figure 8 (Options for infrared instrument connection issues can be checked) and (options for whether to provide voice prompts at the start of batch temperature measurement calibration are available). Figure 8 The option to start batch calibration is available in the settings (and / or to provide a voice prompt when batch temperature measurement calibration is complete is available). Figure 8Batch calibration completion can be checked in the settings.

[0103] The human-computer interaction interface is also used to display the voice configuration interface.

[0104] As a further improvement, in one embodiment, the control host is also used for:

[0105] Configure the device communication display interface, which includes a receive area for displaying received data and / or a send area for displaying sent data;

[0106] The human-computer interaction interface is also used to display the device communication display interface.

[0107] It should be noted that the device communication display interface is as follows: Figure 7 As shown, the device communication display interface is used to display the communication content between each of the heating devices under test and the control host during the temperature calibration process, so as to facilitate troubleshooting by looking at the communication content when problems occur. Specifically, the device communication display interface includes a receive area for displaying received data and / or a send area for displaying sent data, that is, the receive area displays the information sent by each of the heating devices under test during the temperature calibration process, and the send area displays the information sent by the control host to each of the heating devices under test during the temperature calibration process.
