In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0024] Understandably, traditional gas stoves typically use mechanical knobs to control gas flow and fixed-angle nozzles to achieve unidirectional flame emission. During heating, users need to manually adjust the flame intensity based on experience. This method has obvious limitations, such as heat concentration in the center of the pot bottom, slow heating in the outer areas, and low overall heating efficiency. Furthermore, while some products incorporate single-point infrared temperature measurement for flame feedback control, this type of solution lacks sophisticated control strategies.

[0025] In terms of intelligent temperature field control, some existing cooktops use zoned combustion technology, which achieves localized temperature control by independently controlling the gas flow in multiple combustion zones; other products utilize bottom-contact sensors and preset programs to achieve automatic heat adjustment. However, these solutions still suffer from dynamic response lag. For example, contact sensors have a 3-5 second thermal inertia, making it difficult to respond in real time to factors such as changes in cooktop position, external wind interference, and range hood suction, resulting in problems such as untimely heat adjustment, temperature field deviation, and insufficient heating uniformity.

[0026] like Figure 1 As shown, this application provides a stove control system for a stove including a combustion device. The combustion device includes multiple flame-spraying components arranged in a row. Different flame-spraying components correspond to different heating areas of the pot. The stove control system includes a temperature sensing device and a control device. The temperature sensing device is configured to: collect temperature distribution information of the target cookware on the stove, and the temperature distribution information is used to indicate the temperature distribution of the target cookware and the target environmental area within a preset range around the target cookware; The control device is configured to perform spatial mapping processing on the temperature distribution information to obtain a three-dimensional temperature field model corresponding to the target cookware. The three-dimensional temperature field model is used to characterize the temperature distribution in the three-dimensional space of the target cookware and the target environment area. Data extraction and processing of the target temperature field plane is performed on the three-dimensional temperature field model to obtain the surface temperature distribution data of the target temperature field, which corresponds to multiple heating areas of the target cookware. Based on the temperature difference distribution between surface temperature distribution data and reference surface distribution data, a target sub-region whose temperature difference meets the preset difference condition is determined from the target temperature field. The reference surface distribution data is used to indicate the expected temperature field distribution corresponding to the target temperature field under the current cooking conditions. Based on the temperature difference data corresponding to the temperature difference distribution in the target sub-region, the flame operation parameters of the target flame assembly are adjusted until the temperature data corresponding to the target sub-region matches the distribution data of the reference surface.

[0027] By acquiring the temperature distribution of the cookware and its surrounding area through temperature sensing devices, a three-dimensional temperature field model is constructed. Temperature data of key heated surfaces of the target cookware are extracted, temperature deviation areas are automatically identified, and corresponding flame-spraying components are intelligently adjusted to enable real-time closed-loop feedback control of the firepower and the heating state of the bottom of the pot, thereby improving the uniformity and control accuracy of the temperature distribution of the cookware.

[0028] In one embodiment, such as Figure 2 As shown, the temperature sensing device is an infrared sensor array, which is positioned on the range hood facing the stove.

[0029] Specifically, the stoves used in this implementation can be single-burner stoves, double-burner stoves, or multi-burner stoves.

[0030] Preferably, the infrared sensor array adopts a wavelength detection range of 8-14μm, the sampling frequency of the infrared sensor array is 60Hz, and the spatial resolution of the infrared sensor array is 2cm² / pixel.

[0031] Specifically, temperature distribution information refers to the set of temperature values ​​at different locations within a preset spatial area surrounding the target cookware. In one embodiment, the temperature sensing device is an infrared temperature sensing array, and the temperature distribution information can be a two-dimensional infrared image array. The temperature distribution information is a set of two-dimensional infrared image array data with spatial coordinate identifiers, where each pixel corresponds to a temperature value. The three-dimensional temperature field model refers to the temperature distribution dataset within the target cookware and its surrounding environment, and the three-dimensional temperature field model possesses spatial location attributes. The target environment area refers to the area located outside the target cookware and within a preset spatial area surrounding the target cookware. The target environment area is used to sense the boundary conditions and external interference factors of the cookware's heating environment. The temperature distribution data of the target environment area is used to construct the three-dimensional temperature field model to improve the spatial integrity and control accuracy of temperature sensing.

[0032] In one embodiment, the three-dimensional temperature field model refers to a set of temperature distribution data covering the target cookware and its surrounding environment, possessing complete three-dimensional spatial location attributes, used to represent the continuous temperature field distribution between each heating area on the cookware and its environment. In one embodiment, the spatial range covered by the three-dimensional temperature field model can be defined as 0.5m extending upwards from the cookware surface along the direction of the cookware. 3 For spatial regions, a complete model is constructed through spatial interpolation or multi-angle temperature projection.

[0033] Specifically, the control device performs spatial mapping processing on the acquired temperature distribution information, combining the two-dimensional thermal image array data with the three-dimensional structural model of the cookware to reconstruct a three-dimensional temperature field model of the space where the cookware is located. Subsequently, the control device extracts the target temperature field covering the bottom of the cookware from this model, generating surface temperature distribution data of the heated area of ​​the cookware.

[0034] Specifically, the control system retrieves reference surface distribution data corresponding to the current cooking mode, cookware type, and recipe information. This reference surface distribution data characterizes the ideal temperature distribution on the desired temperature surface. The control device spatially aligns the surface temperature distribution data with the reference surface distribution data and calculates the temperature difference distribution between them. It then identifies regions where the temperature difference meets preset difference conditions and determines them as target sub-regions.

[0035] Specifically, each flame-spraying component corresponds to a different area on the bottom of the pot, forming a spatially distributed fire control network. The flame-spraying components are intelligent burners, arranged in a ring. Each flame-spraying component includes 6-10 sets of adjustable burners, a flame direction adjustment mechanism, a gas flow adjustment mechanism, a combustion outlet structure, and a control interface. Both the flame direction adjustment mechanism and the gas flow adjustment mechanism are electrically connected to the control device. The flame direction adjustment mechanism is used to change the flame spray angle, the gas flow adjustment mechanism is used to adjust the gas output, the combustion outlet structure is used to form a flame and adjust the flame shape, and the control interface is used to receive fire parameter commands output by the control device.

[0036] In one embodiment, the flame direction adjustment mechanism is a deflection mechanism driven by a micro stepper motor. The flame direction adjustment mechanism can adjust the spray direction of the nozzle. The flame direction adjustment mechanism is used to move the flame in a direction close to or away from the center of the burner head, such as within a ±30° adjustment range.

[0037] In another embodiment, the flame direction adjustment mechanism is capable of moving up and down and adjusting along the tangential direction of the stove support.

[0038] In one embodiment, the gas flow regulating mechanism is a piezoelectric ceramic gas flow regulating valve with a response time of <50ms. The initial gas flow of each nozzle is the standard flow, and the flow rate can be adjusted individually within ±20% of the standard flow.

[0039] In one embodiment, the flame-spraying assembly is a porous ceramic combustion plate with gradient pore sizes to achieve flame pattern control.

[0040] In one embodiment, such as Figure 3 As shown, the target temperature field plane is an annular temperature field plane, which includes a first-level annular temperature field, a second-level annular temperature field, and a third-level annular temperature field. The reference temperature distribution of the first-level annular temperature field of the reference surface distribution data is 190℃±5℃, the reference temperature distribution of the second-level annular temperature field is 200℃±5℃, and the reference temperature distribution of the third-level annular temperature field is 210℃±5℃.

[0041] In one embodiment, the control device is configured to: Obtain the current flame angle of the target flamethrower component; Based on the first preset correspondence, the target flame angle corresponding to the temperature difference data is determined. The first preset correspondence is used to indicate the mapping relationship between temperature difference and flame angle. When the current flame angle of the target flame assembly is the target flame angle and the target sub-region meets the preset difference conditions, the current flame flow rate and updated temperature difference data of the target flame assembly are obtained. Based on the second preset correspondence, the target flame flow rate corresponding to the updated temperature difference data is determined. The first preset correspondence is used to indicate the mapping relationship between temperature difference and flame flow rate.

[0042] Thus, the control system first adjusts the flame angle to direct the flame towards a lower temperature area, achieving initial correction of the heating position; then it further adjusts the flame flow rate to match the heat intensity with the actual heating requirements, thereby achieving dual coordinated control of flame direction and intensity, dynamically optimizing the heating area and heating intensity, and improving the temperature uniformity inside the cookware.

[0043] Specifically, the control device can acquire real-time angle data of the flame angle adjustment device through encoders, Hall sensors, etc. The current flame angle is used to characterize the current heating range of the target flame component. Adjusting the current flame angle is used to adjust the thermal distribution data. The current flame flow rate is the amount of gas ejected by the flame component per unit time (L / min). The current flame flow rate can be obtained by the flow rate data collected by the flow sensor. The first preset correspondence is the first mapping function between the flame angle and the temperature difference data ΔT. The second preset correspondence is the second mapping function between the flame flow rate and the temperature difference data ΔT. In one embodiment, the first mapping function is:

[0044] Where θ(ΔT) is the target flame angle, and |ΔT| is the absolute value of the temperature difference data.

[0045] In one embodiment, the second mapping function is:

[0046] Where Q0 represents the current flame flow rate, and ΔT' is the updated temperature difference data. The target flame flow rate.

[0047] Specifically, when the temperature difference data ΔT is greater than zero, it indicates that the temperature of the target sub-region is lower than the reference temperature. The control device deflects the target flame angle relative to the current flame angle toward the target sub-region to enhance the heat coverage of the target sub-region. When the temperature difference data ΔT is less than zero, it indicates that the temperature of the target sub-region is higher than the reference temperature. The control device deflects the target flame angle relative to the current flame angle away from the target sub-region to reduce the direct heating intensity of the target sub-region.

[0048] Specifically, when the temperature difference data ΔT is greater than zero, the target flame flow rate is greater than the current flame flow rate; when the temperature difference data ΔT is less than zero, the target flame flow rate is less than the current flame flow rate.

[0049] Specifically, when the current flame angle of the target flame-spraying component is the target flame angle and the temperature of the target sub-region meets the target heating conditions, the target flame-spraying component sprays flame according to the target flame angle and the current flame flow rate. The target heating conditions are the temperature equilibrium state that the target area of ​​the target cookware is expected to reach, and the preset difference conditions are the temperature difference threshold used to trigger the control logic.

[0050] Specifically, when the current flame angle of the target flame assembly is the target flame angle and the target sub-region meets the preset difference conditions, the current flame flow rate and updated temperature difference data of the target flame assembly are obtained. Specifically, the current flame flow rate and updated temperature difference data of the target flame assembly are obtained, and based on the second preset correspondence, the target flame flow rate corresponding to the updated temperature difference data ΔT' is determined. Based on the second preset correspondence, the target flame flow rate corresponding to the updated temperature difference data is determined.

[0051] Specifically, when the current flame angle is the target flame angle and the current flame flow rate is the target flame flow rate, if the target sub-region meets the preset difference condition, the auxiliary operating parameters of the auxiliary flame component are adjusted until the temperature difference between the temperature data corresponding to the auxiliary sub-region and the temperature data corresponding to the target sub-region meets the preset temperature difference condition. The auxiliary sub-region and the target sub-region are set adjacent to each other, and the auxiliary flame component is used to control the temperature data of the auxiliary sub-region.

[0052] In one embodiment, the control device is configured to: When the current flame angle is the target flame angle and the current flame flow rate is the target flame flow rate, if the target sub-region meets the preset difference condition, the auxiliary operating parameters of the auxiliary flame component are adjusted until the temperature difference between the temperature data corresponding to the auxiliary sub-region and the temperature data corresponding to the target sub-region meets the preset temperature difference condition. The auxiliary sub-region and the target sub-region are set adjacent to each other, and the auxiliary flame component is used to control the temperature data of the auxiliary sub-region.

[0053] If the target sub-region still has temperature anomalies, the auxiliary flame-spraying components in the adjacent auxiliary sub-region will be activated to perform local temperature compensation and adjustment. By adjusting the auxiliary operating parameters, the potential local deficiencies of the main heating can be compensated for, thereby achieving more refined multi-region temperature control and improving the overall heating uniformity and cooking quality of the cookware.

[0054] Specifically, the control device monitors the temperature status of the target sub-region in real time. If the temperature difference in the target sub-region meets the preset difference condition, such as if the temperature difference in the target sub-region is greater than 10℃, it is determined that the heat distribution is still uneven. The control device system determines the auxiliary sub-region that is spatially adjacent to the target sub-region and calls the corresponding auxiliary flame-spraying component. The control device adjusts the auxiliary operating parameters of the auxiliary flame-spraying component, such as the flame-spraying angle, flame-spraying flow rate, and flame-spraying duration, so that the auxiliary sub-region is heated or weakened, and the temperature of the auxiliary sub-region is gradually adjusted. When the temperature difference between the auxiliary sub-region and the target sub-region is reduced to within the preset temperature difference condition, the control device determines that the temperature compensation is completed and terminates the current adjustment.

[0055] Specifically, the preset difference condition is a temperature difference threshold used to determine whether the target sub-region is heating abnormally, and the auxiliary operating parameters are the operating parameters for controlling the auxiliary flame-spraying components, such as the auxiliary flame-spraying angle and the auxiliary flame-spraying flow rate.

[0056] In one embodiment, the control device is further configured to: Obtain the target temperature field model, which is used to indicate the desired heating area of ​​the target cookware under the target cooking state and the temperature distribution benchmark of the desired heating area; Spatial analytical processing is performed on the target temperature field model to obtain the reference temperature field plane and the corresponding reference surface distribution data. Based on the temperature field mapping relationship, the data of the target temperature field plane is extracted and processed from the three-dimensional temperature field model to obtain the surface temperature distribution data of the target temperature field. The temperature field mapping relationship is used to indicate the mapping relationship between each target temperature field plane and each reference temperature field plane.

[0057] By acquiring the target temperature field model to clarify the desired heating area and its ideal temperature distribution benchmark, a reference temperature field plane is constructed through spatial analysis, and its corresponding reference surface distribution data is extracted. Then, based on the temperature field mapping relationship, the actual three-dimensional temperature field model is mapped to the target temperature field, and the surface temperature distribution data is extracted. This enables a high-precision spatial comparison analysis between the actual heating state and the ideal heating state of the cookware, significantly improving heating uniformity and control intelligence.

[0058] Specifically, the control device calls the target temperature field model corresponding to the current cooking mode in the preset database. The target temperature field model marks the ideal heating area and the desired temperature distribution. Then, the target temperature field model is spatially segmented to obtain a two-dimensional reference temperature field plane. The reference surface temperature data of each area on the two-dimensional reference temperature field plane is extracted. The three-dimensional temperature field model currently collected by the stove is mapped to the corresponding target temperature field according to the set temperature field mapping relationship. After obtaining the surface temperature distribution data of the target temperature field, the regional temperature difference is compared with the reference surface distribution data to determine the target sub-area that needs to be adjusted.

[0059] Specifically, the target temperature field model is a three-dimensional model of an ideal temperature field preset for different cooking needs. The target temperature field model indicates the desired heating area and temperature reference, and is generated based on the control device's built-in model library or machine learning model inference. The temperature field mapping relationship is the spatial alignment or registration relationship between the preset actual temperature field and the reference plane.

[0060] In one embodiment, the stove control system further includes an image acquisition device; The image acquisition device is configured to: acquire user cooking behavior information, which is used to characterize at least one of the cooking type of the target cookware and the user's cooking action; and acquire cookware information of the target cookware, which is used to determine the heating characteristics of the target cookware. The control device is configured to acquire cooking behavior information and cookware information; Data fusion processing is performed on cooking behavior information and cookware information to obtain target cooking information; Based on the preset relationship of the temperature field strategy, a target temperature field model that matches the target cooking information is determined. The target temperature field model is used to characterize the expected temperature distribution of the target cookware under the current cooking behavior. The preset relationship of the temperature field strategy is used to indicate the mapping relationship between multiple cooking behaviors and multiple target temperature field models.

[0061] By setting up an image acquisition device to obtain user cooking behavior information and cookware information, and then fusing and processing them to generate target cooking information, a target temperature field model suitable for the current cookware and operation mode is matched by a preset temperature field strategy. This achieves accurate identification and matching of the user's actual cooking behavior and cookware characteristics, thereby providing a temperature distribution control strategy that is more in line with the current cooking needs, and improving the adaptability, intelligence and cooking effect of heating.

[0062] In one embodiment, the image acquisition device is electrically connected to the control system, and the effective range of the image acquisition device at least partially covers the stove.

[0063] Specifically, cooking behavior information includes cooking action data and cooking mode data. Cooking action data is used to characterize the user's action characteristics during the cooking process, such as stir-frying, pan-frying, and braising. Cooking mode data characterizes the name or type of dish selected by the user, such as "pan-fried steak" or "stir-fried vegetables". Cooking mode data can also be obtained by the user manually inputting it.

[0064] Specifically, the cookware information includes at least cookware type data, cookware material data, cookware shape data, lid data, and food status data. Cookware type data is used to distinguish different types of cookware for different functions or uses, such as woks, frying pans, soup pots, and hot pot bodies. Cookware shape data is used to distinguish the geometric shape characteristics of the bottom or walls of the pot, such as round pots, square pots, flat-bottomed pots, and curved-bottomed pots. Cookware material data is used to distinguish the heat conduction and heat storage capacity of the cookware, such as iron pots, non-stick pots, stainless steel pots, ceramic pots, and earthenware pots. Lid data is used to indicate whether the pot is currently covered, i.e., whether the pot is in a sealed heating state. Food status data is used to indicate whether the pot is empty, whether food has been added, or whether it contains liquid, to help assess the trend of temperature changes inside the pot.

[0065] Specifically, the target cooking information is a status identifier that integrates the current cooking behavior and cookware characteristics. Based on the target cooking information, a target temperature field model matching the target cooking information is queried from a preset database. The preset temperature field strategy is a mapping data table of preset cooking behaviors and cookware types to corresponding temperature field models.

[0066] Specifically, when the target cookware is detected to be in soup-making mode, the control device controls the flame-spraying components in the central area of ​​the cookware to operate at a higher heat to maintain continuous boiling inside the pot, while controlling the peripheral flame-spraying components to maintain a lower heat to preserve the overall heat retention effect; when the target cookware is detected to be in stir-fry mode, the control device forms a vortex-shaped heat distribution with the center of the cookware as the focal point according to a preset rotating heat excitation strategy; when the target cookware is detected to be in steak-frying mode, the control device controls multiple flame-spraying components to heat in a checkerboard pattern to prevent local overheating of the bottom of the pot from causing the surface of the food to burn.

[0067] Specifically, the control device is also configured as follows: When the oil temperature inside the target cookware exceeds the set critical oil temperature threshold, the output of the target flame-spraying component is reduced; when the image acquisition device detects oil droplet splashing on the surface of the target cookware, the control device determines the location of the splashing area and reduces the flame of the flame-spraying component corresponding to the splashing area; when an oil fire is detected inside the cookware, the control device outputs a fire-off command to shut off the flame output of the flame-spraying component.

[0068] In one embodiment, the control device is further configured to: Wind interference information is obtained based on the flame pattern or temperature field center of gravity drift of the flame-spraying component. Based on wind interference information, the spatial position of the target temperature field in the three-dimensional temperature field model is corrected to obtain an updated target temperature field. Based on the updated target temperature field, extract updated surface temperature distribution data; Based on the temperature difference distribution between the updated surface temperature distribution data and the reference surface distribution data, target sub-regions whose temperature differences meet the preset difference conditions are determined from the target temperature field.

[0069] By acquiring wind interference information based on flame morphology or temperature field centroid drift, the spatial position of the target temperature field in the three-dimensional temperature field model can be dynamically corrected, eliminating the interference of wind-induced flame displacement on temperature data judgment, thereby improving the spatial accuracy of temperature distribution identification.

[0070] In one embodiment, the control device analyzes the flame morphology, such as the flame tilt angle and changes in elongation, using an image acquisition device. In another embodiment, the control device determines whether there is wind interference by analyzing the shift in the temperature center of gravity position in the temperature field data.

[0071] Specifically, if wind interference is detected, the control device adjusts the spatial position of the target temperature field in the three-dimensional temperature field model according to the direction and intensity of the interference. For example, it slightly shifts the temperature field towards the flame offset direction to obtain an updated target temperature field. Based on the corrected target temperature field, data projection and extraction are performed again to generate updated surface temperature distribution data. The updated temperature distribution is compared with the reference surface distribution data to identify target sub-regions whose temperature differences meet preset conditions.

[0072] Specifically, wind interference information is used to characterize the degree and direction of the influence of ambient wind on the flame state, and wind interference information is used to determine whether the temperature field data is affected by wind; temperature field centroid drift refers to the spatial change of the temperature distribution centroid deviating from the geometric center of the cookware; updated target temperature field refers to the target temperature field that has been repositioned after wind interference correction; the updated target temperature field is generated by the control device after calculating the offset based on the wind direction; and reference surface distribution data is used to characterize the target temperature distribution at each location under ideal heating conditions.

[0073] In one embodiment, the control device is configured to: Spatial alignment of the temperature difference distribution between the surface temperature distribution data and the reference surface distribution data is performed to obtain the set of temperature difference data corresponding to the target temperature field plane. The temperature difference data set is filtered to determine the target temperature difference set that meets the preset difference conditions and the target area corresponding to the target temperature difference set; The target region is divided according to rules to obtain target sub-regions.

[0074] Spatially aligning the temperature difference distribution between the surface temperature distribution data and the reference surface distribution data ensures spatial consistency between the actual temperature and the desired temperature. Then, the target area requiring temperature adjustment is selected from the temperature difference data, and the target area is regularly divided into target sub-regions, thereby improving the accuracy of temperature difference identification and the positioning precision of subsequent flame control.

[0075] Specifically, the control device performs spatial coordinate registration between the actual collected surface temperature distribution data and the reference surface distribution data to generate a spatially consistent temperature difference distribution map, obtaining a temperature difference data set ΔT(x,y). The temperature difference data set is then subjected to threshold judgment and cluster analysis to select a set of points that meet the preset difference conditions, forming a target temperature difference set. At the same time, the spatial region corresponding to the target temperature difference set is marked as the target region. Then, an image segmentation algorithm, such as grid division, shape approximation, or region merging, is performed on the target region to divide the target region into several regular target sub-regions. The flame-spraying component can traverse the target sub-regions to regulate the temperature of the target region.

[0076] Specifically, the temperature difference dataset is a set of temperature difference values ​​with spatial location labels. The target temperature difference set is the set of temperature difference points that meet a set threshold. The target temperature difference set represents the abnormal heating area that needs to be prioritized for treatment. The target temperature difference set is obtained through threshold filtering and region clustering algorithms. The target region is the spatial range of temperature difference aggregation. The target sub-region is a regular thermal control unit that further subdivides the target region.

[0077] In one embodiment, the cooktop control system is electrically connected to the range hood, and the control device is further configured to: Obtain the range hood status information, which is used to characterize the airflow intensity of the range hood; Based on the preset relationship of the smoke machine, the flame operation parameters of the target flame-throwing component are adjusted. The preset relationship of the smoke machine is used to indicate the mapping relationship between multiple flame operation parameters and multiple wind intensities.

[0078] In this way, the control device can obtain the wind power of the range hood in real time and automatically adjust the flame operation parameters of the stove according to the preset parameter mapping relationship, so as to realize the intelligent coordinated control of the stove firepower and the range hood suction, thereby improving flame stability and combustion efficiency.

[0079] Specifically, the cooktop control system establishes a communication channel with the range hood, such as through 2.4G or Bluetooth communication.

[0080] Specifically, range hoods have different fan speed settings, and the fan speed of the range hood will affect the flame on the stove. Range hood status information refers to data that reflects the current operating status of the range hood, such as at least one of the following: fan speed setting, fan speed, and real-time airflow.

[0081] Specifically, the control device analyzes the acquired smoke machine status information to identify the current wind intensity level and queries the smoke machine preset relationship table, which represents the mapping relationship between wind intensity and flame operation parameters. The control device finds the corresponding target flame operation parameters based on the current wind intensity, adapts to the current air intake state, and ensures that the flame stability and heating effect are not affected by strong winds.

[0082] Specifically, the range hood status information is data used to characterize the current working status of the range hood, and provides the cooktop with a basis for judging the intensity of wind interference.

[0083] In one embodiment, the control device is configured to: Obtain temperature distribution information of the target cookware on the stove; The temperature distribution information is input into the temperature field reconstruction model to reconstruct the temperature field and obtain the three-dimensional temperature field model corresponding to the target cookware.

[0085] Specifically, the control device acquires the temperature distribution information of the target cookware collected by the temperature sensing device deployed on the stove. The temperature distribution information includes temperature data points at multiple spatial locations on the surface of the target cookware, forming an initial two-dimensional temperature data map. The control device inputs the above temperature distribution information into the temperature field reconstruction model for processing. The temperature field reconstruction model is built based on the convolutional neural network (CNN) architecture. The CNN has multiple convolutional layers, pooling layers, and deconvolutional layers. The CNN is used to extract spatial features and restore features layer by layer from the input initial two-dimensional temperature data map, and finally outputs the three-dimensional temperature field model corresponding to the cookware.

The control device is also configured to: acquire temperature distribution information of the target cookware on the stove; Spatial mapping processing is performed on temperature distribution information and structural depth information to obtain a three-dimensional temperature field model corresponding to the target cookware.

[0087] By fusing structural depth information with temperature distribution information, it is possible to accurately locate temperature data in a spatial coordinate system, thereby constructing a three-dimensional temperature field model that truly reflects the thermal state of the cookware surface and its surrounding area, and improving the spatial accuracy of heat distribution monitoring.

[0088] Specifically, the cooktop control system uses a depth image acquisition device (such as a ToF camera, structured light module, or binocular camera) to spatially scan the target cooktop and obtain the structural depth information of the cooktop surface, that is, the height data of each pixel on the cooktop surface in space, forming a three-dimensional shape model of the cooktop. Based on image registration or point cloud reconstruction technology, the control device spatially correlates the temperature distribution information with the structural depth information to construct a three-dimensional temperature field model of the target cooktop.

[0089] Specifically, the depth image acquisition device is an imaging device that can acquire the distance from each pixel of an object to the sensor. The structural depth information is used to characterize the depth data of the vertical coordinate of each point on the surface of the target cookware in space. The structural depth information can characterize the spatial shape and placement of the cookware.

[0091] Specifically, the visible light image acquisition device is used to acquire images of the cookware on the stove in real time. The visible light image information is used to characterize the geometry, placement direction, and relative coordinate position of the target cookware. The control device performs edge extraction and target recognition processing on the visible light image, extracts the relative position of the cookware's outer contour, bottom area, and stove structure, establishes a two-dimensional cookware boundary model, and can combine depth estimation to infer the three-dimensional shape of the cookware. The control device combines the temperature distribution information obtained from the infrared temperature map or temperature sensor grid, maps the temperature values ​​to the spatial areas identified in the cookware image according to the corresponding pixels or coordinate points, and fuses the above two-dimensional cookware boundary model with temperature data to form a three-dimensional temperature field model with spatial position attributes, where each spatial point contains the temperature value and the actual position of the cookware structure.
