Description

Technical Field

[0001] This invention relates to the field of intelligent control technology for barbecue ovens, and particularly to an intelligent control system, method, and barbecue oven for barbecue ovens. Background Technology

[0002] Currently, in traditional grilling, the power control of grills, as household appliances, mainly relies on manual adjustment by the user or preset fixed programs. However, different ingredients absorb and respond to heat differently during grilling. For example, meat, vegetables, and seafood have different heat absorption characteristics, and factors such as the thickness, size, and moisture content of the ingredients also affect their heat absorption process. Traditional control methods struggle to dynamically adjust the grill's power output based on the actual heat absorption of the ingredients, leading to unstable cooking results. This can result in problems such as burnt surfaces, undercooked interiors, or excessively long cooking times, while also wasting energy. During grilling, various parameters reflecting cooking effects (such as temperature gradient parameters and weight change rate parameters) constantly change with the grilling power. Traditional technologies often only focus on the absolute values ​​of cooking parameters, neglecting the rate of change of these parameters. In reality, the rate of change of cooking parameters can more accurately reflect the cooking state and progress of ingredients. For example, an excessively rapid temperature rise may cause the surface of the food to char quickly while the inside remains uncooked; conversely, a slow temperature change may prolong cooking time, affecting the taste and nutritional value of the ingredients. The lack of quantitative analysis of the rate of change of cooking parameters prevents barbecue grills from precisely controlling their operation based on the real-time cooking status of the ingredients. Therefore, it is necessary to introduce technologies such as artificial intelligence to construct an intelligent control scheme that can automatically determine whether power adjustments are needed based on the real-time cooking parameters of the barbecue grill and provide precise power adjustments. This would enable intelligent control of the barbecue grill, improving cooking results and energy efficiency. Summary of the Invention

[0003] This invention provides an intelligent control system, method, and grill for a barbecue grill. Based on the assigned scores of all cooking parameters at each moment within an analysis period prior to the current moment, it obtains the rate of change of these assigned scores for each cooking parameter within that analysis period. This facilitates the subsequent plotting of rate curves. Based on the rate of change of these assigned scores and the grilling power parameter, a rate curve for all cooking parameters at the current moment is obtained. This enables the plotting of a broken line that comprehensively reflects the rate of change of each cooking parameter within the analysis period prior to the current moment. Furthermore, based on the rate curve of all cooking parameters at the current moment, the rate-related tendency value of the grill at the current moment is obtained. This is further based on the rate of change of these assigned scores and the grilling power parameter within the analysis period prior to the current moment. The system obtains the rate of change curves for all cooking parameters of the barbecue grill at the current moment, enabling the plotting of broken lines that fully reflect the rate of change of each type of cooking parameter over the analysis period prior to the current moment. Based on these rate of change curves, the system obtains the rate-related tendency value of the barbecue grill at the current moment, accurately quantifying the correlation between the rate of change tendencies of all cooking parameters at the current moment. Based on this rate-related tendency value, the system obtains the power adjustment judgment value for the barbecue grill at the current moment, quantifying whether power adjustment is needed. Finally, based on this power adjustment judgment value, the system obtains the intelligent control result of the barbecue grill at the current moment, dynamically adjusting the power output of the grill to address the differences in heat absorption of different ingredients, significantly improving the cooking effect and energy efficiency of the barbecue grill.

[0050] In this embodiment, the barbecue grill is a cooking appliance that uses a smart control system to cook food. It directly or indirectly heats the ingredients through a heat source (such as gas, electric heating element, etc.) to achieve cooking effects such as grilling and smoking.

[0051] In this embodiment, the analysis time period is the time period used to obtain all types of cooking parameters.

[0052] In this embodiment, each moment is a moment selected from the analysis time period before the current moment, and the time length between each adjacent moment is the same.

[0053] In this embodiment, the score values ​​for all cooking parameters are numerical values ​​assigned to the degree of grilling effect of the food in the grill oven as represented by all cooking parameters of the grill oven at each time point in the analysis period before the current time.

[0054] In this embodiment, the rate of change of the assigned score value is obtained based on the assigned score values ​​of all types of cooking parameters of the barbecue oven at each moment in the analysis period before the current moment, and can reflect the rate of change of the assigned score value of each type of cooking parameter of the barbecue oven at each moment in the analysis period before the current moment.

[0055] In this embodiment, the grilling power parameter is the parameter of the heat generated by the grill per unit time, usually expressed in watts (W) or kilowatts (kW), which is an important indicator for measuring the heating capacity of the grill.

[0056] In this embodiment, the rate of change of each type of cooking parameter of the barbecue oven at the current moment is a broken line obtained based on the rate of change of the assigned values ​​of all types of cooking parameters of the barbecue oven at each moment in the analysis period before the current moment and the barbecue power parameter, which can completely reflect the rate of change of each type of cooking parameter of the barbecue oven in the analysis period before the current moment.

[0057] In this embodiment, the rate of variation correlation tendency value of the barbecue oven at the current moment is a value obtained based on the rate of variation lines of all cooking parameters of the barbecue oven at the current moment, which can characterize the degree of correlation of the rate of variation tendency among all cooking parameters of the barbecue oven at the current moment.

[0058] In this embodiment, the power adjustment determination value of the barbecue grill at the current moment is obtained based on the rate of change correlation tendency value of the barbecue grill at the current moment, which is a determination value that can characterize whether the barbecue grill needs to adjust its power at the current moment.

[0059] In this embodiment, the intelligent control result of the barbecue oven at the current moment is the result of adjusting the barbecue power parameters of the barbecue oven at the next adjacent moment based on the power adjustment judgment value of the barbecue oven at the current moment.

[0060] The beneficial effects of the above technology are as follows: Based on the assigned values ​​of all cooking parameters of the barbecue oven at each moment within the analysis period prior to the current moment, the rate of change of the assigned values ​​of all cooking parameters of the barbecue oven at each moment within the analysis period prior to the current moment is obtained, which facilitates the subsequent plotting of the rate of change curve. Based on the rate of change of the assigned values ​​of all cooking parameters of the barbecue oven at each moment within the analysis period prior to the current moment and the barbecue power parameter, the rate of change curve of all cooking parameters of the barbecue oven at the current moment is obtained, realizing the plotting of a broken line that can completely reflect the rate of change of each type of cooking parameter of the barbecue oven within the analysis period prior to the current moment. Furthermore, based on the rate of change curve of all cooking parameters of the barbecue oven at the current moment, the rate of change correlation tendency value of the barbecue oven at the current moment is obtained. Based on the rate of change of the assigned values ​​of all cooking parameters of the barbecue oven at each moment within the analysis period prior to the current moment and the barbecue power parameter, the barbecue... The rate of change curves for all cooking parameters of the grill at the current moment are plotted to fully reflect the rate of change of each type of cooking parameter during the analysis period prior to the current moment. Based on these rate of change curves, the correlation value of the grill's rate of change at the current moment is obtained, enabling precise quantification of the correlation between the rate of change trends of all cooking parameters at the current moment. Based on this correlation value, the power adjustment judgment value for the grill at the current moment is obtained, quantifying whether power adjustment is needed. Finally, based on this power adjustment judgment value, the intelligent control result of the grill at the current moment is obtained, enabling dynamic adjustment of the grill's power output to accommodate differences in the heat absorption of different ingredients, significantly improving the grill's cooking effect and energy efficiency.

[0061] Example 2: Based on Example 1, the intelligent control system for the barbecue grill includes an acquisition module, comprising:

[0062] The preparation submodule is used to treat the time period during which the barbecue grill has been working as the analysis period when the time since the grill started working exceeds the preset time period.

[0063] The assignment module is used to obtain the assigned score value for each type of cooking parameter of the barbecue oven at all times within the analysis period before the current time, based on the analysis of all cooking parameters of the barbecue oven at all times within the analysis period before the current time.

[0064] In this embodiment, the preset time length is a pre-set time length used to determine the analysis time period, such as 20 seconds.

[0065] The beneficial effects of the above technology are as follows: it clarifies the method for determining the analysis time period, which facilitates the subsequent acquisition of the scoring values ​​of each type of cooking parameter of the barbecue oven at all times within the analysis time period before the current time, based on the cooking parameters of the barbecue oven at all times within the analysis time period before the current time. This enables the scoring of the degree of grilling effect of the food in the barbecue oven as represented by all types of cooking parameters at each time within the analysis time period before the current time.

[0066] Example 3: Based on Example 2, the intelligent control system for the barbecue oven includes a molecular module, comprising:

[0067] The first assignment unit is used to obtain all cooking parameters of the barbecue oven at each time point in the analysis period before the current time. All cooking parameters include temperature gradient parameters and weight change rate parameters.

[0068] The second assignment unit is used to obtain the assigned score value of each type of cooking parameter of the barbecue oven at each moment in the analysis period before the current moment, based on each type of cooking parameter and the corresponding cooking parameter assignment model at each moment in the analysis period before the current moment.

[0069] In this embodiment, the temperature gradient parameter is the rate of change of the difference between the surface temperature (higher when the surface temperature is higher when the oven is heated) and the internal temperature (lower) of the food (e.g., meat slices) in the grill oven with depth (e.g., in the thickness direction) during cooking or heating.

[0070] In this embodiment, the weight change rate parameter is a parameter of the degree of weight change of food (e.g., meat slices) in the barbecue oven during the grilling process, and is usually expressed as a percentage.

[0071] In this embodiment, the scoring model for each type of cooking parameter is trained by taking a large number of pre-collected cooking parameters of each type of cooking oven at different times as training input and manually annotated scoring values ​​of the corresponding cooking parameters of the corresponding time as training output. The trained neural network model can take the cooking parameters of each type of cooking oven at each time in the analysis period before the current time as input, and output the scoring values ​​of the corresponding cooking parameters of the corresponding time in the analysis period before the current time.

[0072] The beneficial effects of the above technology are as follows: it clarifies the specific parameters of all types of cooking parameters of the barbecue oven at each moment in the analysis period before the current moment, and obtains the assigned scores of each type of cooking parameter of the barbecue oven at each moment in the analysis period before the current moment based on the assigned scores of each type of cooking parameter of the barbecue oven at each moment in the analysis period before the current moment, thereby realizing the assignment of scores to the degree of grilling effect of the food in the barbecue oven as represented by all types of cooking parameters of the barbecue oven at each moment in the analysis period before the current moment.

[0073] Example 4: Based on Example 1, the intelligent control system for the barbecue grill includes a processing module, comprising:

[0074] The first processing submodule is used to take the difference between the assigned score of each type of cooking parameter of the barbecue oven at each moment in the analysis period before the current moment and the assigned score of the corresponding type of cooking parameter at the previous adjacent moment as the adjacent difference of the assigned score of the corresponding type of cooking parameter at the corresponding moment in the analysis period before the current moment.

[0075] The second processing submodule is used to take the quotient between the adjacent differences of the assigned values ​​of each type of cooking parameter at each moment in the analysis period before the current moment and the assigned value of the corresponding type of cooking parameter at the previous adjacent moment as the variability of the assigned value of the corresponding type of cooking parameter at the corresponding moment in the analysis period before the current moment.

[0076] In this embodiment, the previous adjacent time of each time is the time that is chronologically preceding each time in the time period during which the barbecue oven is analyzed before the current time.

[0077] The beneficial effects of the above technology are: based on the assigned values ​​of all types of cooking parameters of the barbecue oven at each moment in the analysis period before the current moment, the rate of change of the assigned values ​​of all types of cooking parameters of the barbecue oven at each moment in the analysis period before the current moment can be obtained, which facilitates the subsequent drawing of the rate of change line.

[0078] Example 5: Based on Example 1, the intelligent control system for the barbecue grill includes a calculation module, comprising:

[0079] The first drawing submodule is used to take the values ​​of the barbecue power parameters of the barbecue oven at all times in the analysis period before the current time as the horizontal axis value, and the rate of change of the assigned values ​​of each type of cooking parameter of the barbecue oven at the corresponding time in the analysis period before the current time as the vertical axis value, so as to obtain all the rate of change points of each type of cooking parameter of the barbecue oven in the analysis period before the current time.

[0080] The second drawing submodule is used to treat all variable points with the same x-coordinate among all variable points of each type of cooking parameter in the analysis period before the current time as a merged variable point group for the corresponding type of cooking parameter in the analysis period before the current time; and to treat the remaining variable points of each type of cooking parameter in the analysis period before the current time, excluding those belonging to the merged variable point group (containing at least two variable points), as the first retained variable points for the corresponding type of cooking parameter in the analysis period before the current time. All variable points within each merged variable point group of the parameters are merged to obtain all second retained variable points of each type of cooking parameter of the barbecue oven in the analysis period before the current time. All first retained variable points and all second retained variable points of each type of cooking parameter of the barbecue oven in the analysis period before the current time are used as construction points of the corresponding type of cooking parameter of the barbecue oven in the analysis period before the current time. All construction points of each type of cooking parameter of the barbecue oven in the analysis period before the current time are connected in ascending order of horizontal coordinate to obtain the variable line of the corresponding type of cooking parameter of the barbecue oven at the current time.

[0081] The calculation submodule is used to obtain the rate-related tendency value of the grill at the current moment based on the rate of change of all cooking parameters of the grill at the current moment.

[0082] In this embodiment, the merging is achieved by taking the mean of the ordinates of all variable points in each merged variable point group of each type of cooking parameter in the analysis period before the current time of the barbecue oven, and using it as the new ordinate, while keeping the abscissa unchanged. The obtained new coordinate point is then used as the second retained variable point corresponding to the merged variable point group of the corresponding type of cooking parameter in the analysis period before the current time of the barbecue oven.

[0083] The beneficial effects of the above technology are as follows: Based on the rate of change of the assigned values ​​of all types of cooking parameters and the grilling power parameters of the grill at each moment in the analysis period before the current moment, the rate of change of all types of cooking parameters of the grill at the current moment is obtained, realizing the drawing of a broken line that can completely reflect the rate of change of each type of cooking parameter of the grill during the analysis period before the current moment. This embodiment provides a detailed method for drawing a broken line graph that can completely reflect the rate of change of each type of cooking parameter of the grill during the analysis period before the current moment.

[0086] The second calculation unit is used to take the similarity between the rate lines of all cooking parameters of the barbecue oven at the current time as the rate correlation value of the barbecue oven at the current time, and take the similarity between the comparison rate lines of all cooking parameters of the barbecue oven at the current time as the comparison rate correlation value of the barbecue oven at the current time, and take the difference (ab) between the rate correlation value (a) and the comparison rate correlation value (b) of the barbecue oven at the current time as the rate correlation tendency value of the barbecue oven at the current time.

[0087] In this embodiment, based on all the comparative rate of change points of each type of cooking parameter of the barbecue oven during the analysis period before the current time, the comparative rate of change line of each type of cooking parameter of the barbecue oven at the current time is obtained, which is:

[0088] The second drawing submodule loops through all the comparison rate points of each type of cooking parameter of the barbecue oven in the time period before the current time (treating the comparison rate points as rate points) to obtain the comparison rate line of each type of cooking parameter of the barbecue oven at the current time.

[0089] In this embodiment, similarity is the degree of similarity between the rate lines of variation of all cooking parameters of the barbecue oven at the current moment, calculated based on existing technologies (such as correlation coefficients, feature extraction, and machine learning).

[0090] The beneficial effects of the above technology are as follows: based on the rate of change of all cooking parameters of the grill at the current moment, the rate of change correlation tendency value of the grill at the current moment is obtained, and the correlation degree of the rate of change tendency among all cooking parameters of the grill at the current moment is accurately quantified.
