Description

Technical Field

[0001] The present invention relates to the technical field of barbecue oven intelligent control, and in particular to an intelligent control system and method for a barbecue oven and a barbecue oven. Background Art

[0002] At present, in the traditional barbecue cooking process, the power control of the barbecue grill as a household appliance mainly relies on the user's manual adjustment or based on a preset fixed program. However, there are significant differences in the absorption and response of heat by different ingredients during the barbecue process. For example, the heat absorption characteristics of meat, vegetables, seafood and other ingredients are different, and factors such as the thickness, size, and moisture content of the ingredients will also affect their heat absorption process. It is difficult for traditional control methods to dynamically adjust the power output of the barbecue grill according to the actual heat absorption of the ingredients, resulting in unstable cooking effects, and problems such as burnt surface of the ingredients, undercooked inside, or too long cooking time. At the same time, it will also cause energy waste. During the barbecue process, various parameters that can reflect the cooking effect (such as temperature gradient parameters, weight change rate parameters, etc.) will continue to change with the change of barbecue power. Traditional technologies often only focus on the absolute values ​​of cooking parameters, but ignore the change rate of these parameters. In fact, the rate of change of cooking parameters can more accurately reflect the cooking status and progress of ingredients. For example, if the temperature rises too fast, the surface of the ingredients may quickly burn, while the inside is not cooked; if the temperature changes too slowly, the cooking time may be prolonged, affecting the taste and nutrition of the ingredients. The lack of quantitative analysis of the rate of change of cooking parameters makes it impossible for the barbecue oven to accurately control the real-time cooking status of the ingredients. Therefore, it is necessary to introduce artificial intelligence and other related technologies to build an intelligent control solution that can automatically determine whether power adjustment is needed based on the real-time cooking parameters of the barbecue oven and provide accurate power adjustment, so as to realize intelligent control of the barbecue oven and improve cooking effects and energy efficiency. Summary of the invention

[0003] The present invention provides an intelligent control system, method and barbecue oven for a barbecue oven, which are used to obtain the score value variation rate of all types of cooking parameters of the barbecue oven at each moment in the analysis time period before the current moment according to the score value variation rate of all types of cooking parameters of the barbecue oven at each moment in the analysis time period before the current moment, so as to facilitate the subsequent drawing of the variation rate line, and obtain the variation rate line of all types of cooking parameters of the barbecue oven at the current moment according to the score value variation rate of all types of cooking parameters of the barbecue oven at each moment in the analysis time period before the current moment and the barbecue power parameter, so as to realize the drawing of a broken line that can completely reflect the variation rate of each type of cooking parameter of the barbecue oven in the analysis time period before the current moment, and then obtain the variation rate related tendency value of the barbecue oven at the current moment according to the variation rate line of all types of cooking parameters of the barbecue oven at the current moment, and obtain the variation rate related tendency value of the barbecue oven at the current moment according to the score value variation rate of all types of cooking parameters of the barbecue oven at each moment in the analysis time period before the current moment and the barbecue power parameter, Parameters, the rate of change lines of all types of cooking parameters of the barbecue grill at the current moment are obtained, and the drawing of a broken line that can fully reflect the rate of change of each type of cooking parameter of the barbecue grill in the analysis time period before the current moment is realized.
