[0039] After introducing the technical terms used in this application, the technical solutions provided by the embodiments of this application will be described in detail below.
[0040] First, the temperature control system 100 provided in the embodiments of this application will be described in detail, see reference. Figure 1 As shown, the temperature control system 100 provided in this application embodiment includes at least: a power module 110, a controller 120, a power metering module 130, and a heating element in a closed space; the power metering module 130 is connected to the power module 110 and the heating element in the closed space, and the controller 120 is connected to the power module 110 and the power metering module 130.

[0042] The power module 110 is used to provide input power to the heating element and also to receive power adjustment commands sent by the controller 120, and adjust the input power of the heating element according to the total power consumption in the power adjustment command;
[0043] The power metering module 130 is used to detect the current input power of the heating element and send it to the controller 120.
[0044] In one possible implementation, the controller 120 is specifically configured to determine a first adjustment time corresponding to the internal temperature of the sealed container reaching the target temperature based on the temperature rise rate of the heating element; determine a second adjustment time based on the ratio of the heat dissipation rate of the sealed container where the heating element is located to the temperature rise rate of the heating element; determine a target adjustment time based on the first and second adjustment times; determine a target electrical power value corresponding to reaching the target temperature within the target adjustment time; and determine the total power consumption within the target adjustment time based on the target electrical power value.

[0053] The switch module 150 is used to receive an emergency stop command sent by the controller 120 and disconnect the power input channel between the heating element in the enclosed space and the power module 110.
[0054] This application provides a temperature control method, see embodiments thereof. Figure 2 As shown, the general flow of the temperature control method provided in this application embodiment is as follows:
[0055] Step 201: Obtain the target temperature.
[0056] In practical applications, users set the temperature by inputting the corresponding temperature value through the human-machine interface, pressing the corresponding button, or adjusting the corresponding knob. This causes the corresponding device to generate an external control command, which is then input to the controller. After receiving the external control command, the controller determines the temperature contained in the external control command as the target temperature. The target temperature is obtained by the controller from the received external control command and is generally the temperature that the user-sets the sealed container needs to reach inside.
[0057] Step 202: Determine the temperature rise rate of the heating element and the heat dissipation rate of the sealed container in which the heating element is located based on the target temperature.
[0058] In practical applications, a heating element refers to a heating device whose electrical heating characteristics remain constant at a specific temperature. The heat dissipation characteristics of the heating element within a sealed container also remain constant at a specific temperature. Therefore, before temperature control, the heating temperature rise characteristics of the heating element (i.e., the rate of temperature rise at various temperatures) can be obtained through testing. Simultaneously, the heat dissipation characteristics of the sealed container containing the heating element (i.e., the rate of heat dissipation at various temperatures) can also be obtained during testing. These measured rates of temperature rise and heat dissipation of the sealed container at various temperatures can be saved. For details on the heating temperature rise characteristics and the heat dissipation characteristics of the sealed container containing the heating element, please refer to [reference needed]. Figure 3 As shown. After determining the target temperature, the temperature rise rate of the heating element and the heat dissipation rate of the sealed container containing the heating element can be determined based on the target temperature. In specific implementation, before obtaining the target temperature, the temperature rise rate of the heating element at various temperatures and the heat dissipation rate of the sealed container containing the heating element at various temperatures can be tested in advance. Specific methods can be adopted, but are not limited to, the following:
[0059] Under different input power conditions of the heating element, the internal temperature of the sealed container where the heating element is located and the temperature rise rate of the heating element corresponding to the internal temperature of the sealed container are detected and saved. The internal temperature of the sealed container where the heating element is located and the heat dissipation rate of the sealed container corresponding to the internal temperature of the sealed container are detected and saved.
[0060] In practical applications, to ensure the accuracy of the test, the temperature at the internal geometric center of the sealed equipment is taken as the internal temperature of the sealed equipment. Before temperature control, the heating element is placed inside the sealed equipment, and the input power of the heating element is continuously increased. During this process, high-precision temperature testing equipment is used to measure the temperature at the internal geometric center of the sealed equipment, the temperature of the heating element, and the temperature of the sealed equipment, and the temperature acquisition time is recorded. Based on the temperature at the internal geometric center of the sealed equipment, the temperature of the heating element, and the temperature acquisition time, the average rate of temperature change of the heating element can be obtained within the temperature range from the internal geometric center of the sealed equipment to the preset temperature. This average rate of change is taken as the temperature rise rate at the midpoint of the temperature change range at the internal geometric center of the sealed equipment. For example, when the temperature at the internal geometric center of the sealed equipment is 25℃, the temperature of the heating element is T1, and the data collection time is t1. The preset temperature rise for the internal geometric center of the sealed equipment is 10℃, meaning that when the temperature at the internal geometric center of the sealed equipment is 35℃, the temperature of the heating element is T2, and the data collection time is t2. Therefore, when the temperature at the internal geometric center of the sealed equipment is 30℃, the temperature rise rate V1 of the heating element is... This method allows for the determination and storage of the internal temperatures of the sealed container containing the heating element and the corresponding temperature rise rates of the heating element within the range of input power variation. Similarly, based on the temperature at the internal geometric center of the sealed device, the temperature of the sealed device itself, and the temperature acquisition time, the average rate of temperature change of the sealed device can be obtained within the temperature range from the internal geometric center to a preset temperature. This average rate of change is then used as the heat dissipation rate at the midpoint of the temperature change range at the internal geometric center of the sealed device. This method further allows for the determination and storage of the internal temperatures of the sealed container containing the heating element and the corresponding heat dissipation rates of the sealed container within the range of input power variation.
[0061] Step 203: Determine the total power consumption of the heating element when the internal temperature of the sealed container reaches the target temperature, based on the temperature rise rate of the heating element and the heat dissipation rate of the sealed container in which the heating element is located.
[0062] In practical applications, heating the interior of a sealed container to a specific temperature is an integral process of the input power of the heating element with respect to time, that is, the process of the electrical power input to the heating element doing work, as shown in the following formula:
[0063]
[0064] Where T is the target temperature, ΔT is the temperature change of the heating element, δT is the temperature change of the sealed container, ΔP is the change of the input power of the heating element, ΔV is the change of the input voltage of the heating element, and ΔI is the change of the input current of the heating element. The temperature inside the sealed container is actually the difference between the temperature released by the heating element and the temperature dissipated by the heat in the sealed container. In order to make the temperature inside the sealed container reach the target temperature, the electrical work input to the heating element includes two parts: one part is the electrical work to make the temperature released by the heating element reach the target temperature, and the other part is the electrical work to compensate for the temperature drop caused by the heat dissipation of the sealed container. When determining the temperature rise rate of the heating element and the heat dissipation rate of the sealed container where the heating element is located, the target adjustment time required for the internal temperature of the sealed container to reach the target temperature can be calculated. Substituting the target adjustment time, the temperature rise rate of the heating element, and the heat dissipation rate of the sealed container where the heating element is located into equation (1) can further determine the change in the input power of the heating element corresponding to the internal temperature of the sealed container reaching the target temperature, and take the change in the input power of the heating element as the total power of the heating element. In practical implementation, the total power consumption of the heating element when the internal temperature of the sealed container reaches the target temperature is determined based on the temperature rise rate of the heating element and the heat dissipation rate of the sealed container in which the heating element is located. This can be achieved, but is not limited to, the following methods:
[0065] First, determine the first adjustment time corresponding to the internal temperature of the sealed container reaching the target temperature based on the temperature rise rate of the heating element;
[0066] Then, the second adjustment time is determined based on the ratio of the heat dissipation rate of the sealed container in which the heating element is located to the temperature rise rate of the heating element.
[0067] Next, the target adjustment time is determined based on the first adjustment time and the second adjustment time;
[0068] Finally, the target electrical work value corresponding to reaching the target temperature within the target adjustment time is determined, and the total power consumption within the target adjustment time is determined based on the target electrical work value.
[0069] In practical applications, the first adjustment time is the time it takes for the electrical work to reach the target temperature as the heating element heats up. The second adjustment time is the time it takes for the electrical work to compensate for the decrease in temperature due to heat dissipation in the sealed container. The first adjustment time is obtained by dividing the target temperature by the temperature rise rate of the heating element corresponding to the target temperature. The ratio of the heat dissipation rate of the sealed container containing the heating element at the target temperature to the temperature rise rate of the heating element at the target temperature is used as a proportional coefficient to increase the electrical work time. The result of multiplying this proportional coefficient by a preset increase time is used as the second adjustment time, where the preset time is generally set to 1 second. The target adjustment time is the time corresponding to the integral of the input power of the heating element, which is also the total time for electrical work. The target adjustment time is the sum of the first and second adjustment times. After determining the target adjustment time, the target adjustment time, the temperature rise rate of the heating element and the heat dissipation rate of the sealed container where the heating element is located can be substituted into equation (1) to further determine the target electrical power value corresponding to the internal temperature of the sealed container of the heating element reaching the target temperature. Based on the target electrical power value, the change in the input power of the heating element can be further determined, and the change in the input power of the heating element can be used as the total power consumption of the heating element.
[0070] Step 204: Obtain the current input power of the heating element.
[0071] In practical applications, the current input power of the heating element can generally be measured by a power metering device. The power metering device can measure the current input voltage and current of the heating element in real time, thereby determining the current input power of the heating element and sending it to the controller.
[0072] Step 205: If the difference between the current input power of the heating element and the total power consumption is greater than the first threshold, adjust the input power of the heating element according to the total power consumption.
[0073] In practical applications, after obtaining the current input power of the heating element, the difference between the current input power of the heating element and the total power consumption is determined and compared with a first threshold. The first threshold refers to the allowable error value between the current input power of the heating element and the total power consumption. The comparison result may include, but is not limited to, the following two:
[0074] The first scenario: If the difference between the current input power of the heating element and the total power consumption is greater than the first threshold, the input power of the heating element is adjusted according to the total power consumption.
[0075] In practical applications, if the difference between the current input power of the heating element and the total power consumption exceeds a first threshold, it means that the current input power of the heating element is insufficient to raise the internal temperature of the sealed container to the target temperature. Therefore, the input power of the heating element needs to be adjusted based on the total power consumption. In specific implementations, adjusting the input power of the heating element based on the total power consumption can be achieved using, but is not limited to, the following methods:
[0076] Adjust the input voltage and / or input current to the heating element according to the total power consumption.
[0077] In practical applications, after determining the total power consumption, the method for adjusting the input power of the heating element can be, but is not limited to, the following three: First, the controller determines the target input voltage of the heating element based on the total power consumption, generates a power adjustment command based on the target input voltage, and sends it to the power supply connected to the heating element, so that the power supply adjusts the input voltage of the heating element according to the target input voltage in the power adjustment command. Second, the controller determines the target input current of the heating element based on the total power consumption, generates a power adjustment command based on the target input current, and sends it to the power supply connected to the heating element, so that the power supply adjusts the input current of the heating element according to the target input current in the power adjustment command. Third, the controller determines the target input voltage and target input current of the heating element based on the total power consumption, generates a power adjustment command based on the target input voltage and target input current, and sends it to the power supply connected to the heating element, so that the power supply adjusts the input voltage and input current of the heating element according to the target input voltage and target input current in the power adjustment command. The method for adjusting the input power of the heating element can be selected according to actual requirements such as the output range of the power supply connected to the target element and the operating voltage and current range of the heating element.
[0078] In this way, by determining the temperature rise rate of the heating element and the heat dissipation rate of the sealed container where the heating element is located based on the target temperature, the total power consumption of the heating element when the internal temperature of the sealed container reaches the target temperature is determined. The input power of the heating element is adjusted according to the total power consumption. This is based on the constant electrothermal characteristics and constant heat dissipation characteristics of the heating element in the sealed container. From the perspective of the work done by the electricity input to the heating element in heating the internal temperature of the sealed container to a specific temperature, the temperature is controlled by changing the input power of the heating element. Temperature control is achieved from the perspective of the characteristics of the components and the heating data including the temperature rise rate and heat dissipation rate. This can further improve the control accuracy and avoid the influence of insufficient accuracy of temperature sensors that directly measure the temperature on temperature control.
[0079] The second scenario: When the difference between the current input power of the heating element and the total power consumption is less than or equal to the first threshold, a temperature setting completion message is generated.
[0080] In practical applications, when the difference between the current input power of the heating element and the total power consumption is greater than or equal to the first threshold, it means that the current input power of the heating element can make the internal temperature of the sealed container of the heating element reach the target temperature without adjusting the input power of the heating element. At this time, the controller sends the temperature setting information back to the user.
[0081] In one possible implementation, after adjusting the input power to the heating element according to the total power consumption, the method further includes:
[0082] First, obtain the calibration temperature.
[0083] Then, when the difference between the corrected temperature and the target temperature is greater than the second threshold, the power deviation between the current input power of the heating element and the total power consumption corresponding to reaching the target temperature is detected, and the input power of the heating element is adjusted according to the power deviation.
[0084] In practical applications, the calibration temperature is a temperature collected in real-time by a temperature sensor positioned at the geometric center of the enclosed space for temperature comparison and correction. The temperature sensor collects the calibration temperature in real time and returns it to the controller. Upon receiving the calibration temperature, the controller determines if the difference between the calibration temperature and the target temperature exceeds a second threshold. If so, it detects the power deviation between the current input power of the heating element and the total power required to reach the target temperature, and adjusts the input voltage and / or current of the heating element based on this power deviation to correct the input power of the heating element. The second threshold is the maximum allowable deviation between the calibration temperature and the target temperature. This real-time calibration further improves the accuracy of temperature control.
[0085] In one possible implementation, after obtaining the current input power of the heating element, the method further includes:
[0086] When the current input power of the heating element is determined to be greater than the third threshold, the control stops inputting power to the heating element.
[0087] In practical applications, the third threshold is the maximum input power that the heating element can withstand. After obtaining the current input power of the heating element, the controller compares it with the third threshold. If the current input power is less than the third threshold, subsequent operations continue. If the current input power is greater than the third threshold, the controller disconnects the switch between the power supply and the heating element, thus cutting off the power input channel between the heating element and the power module in the enclosed space, allowing power to be input to the heating element. In this way, setting a third threshold improves the safety of temperature control.
