[0127] In current smart kitchen applications, smart kitchen appliances need to have appliance status recognition capabilities to determine the corresponding cooking plan or switch the current cooking status based on the specific appliance status, thereby improving the intelligence level of the appliances and enhancing the accuracy and safety of smart kitchen appliances in application.

[0128] Current methods for identifying kitchen appliances match them using electronic tags that integrate information about the target cookware and stove, and identify their status by obtaining a single physical parameter of the target cookware. This approach lacks accuracy, leading to poor cooking results and a subpar user experience when using smart kitchen appliances. Therefore, improving the accuracy of kitchen appliance status identification is crucial.

[0129] This invention discloses a method and apparatus for kitchenware status recognition. By determining the first kitchenware information of the target cookware and the second kitchenware information of the target stove, a kitchenware matching operation can be performed to obtain the current kitchenware status of the target cookware and generate a corresponding interactive signal to be sent to the target stove. The kitchenware status of the target cookware is determined and verified on the target stove side, which improves the reliability and accuracy of kitchenware status recognition and thus helps to improve the user experience of smart kitchenware.

[0130] Example 1

[0131] Please see Figure 1 , Figure 1 This is a flowchart illustrating a method for identifying the state of kitchen utensils disclosed in an embodiment of the present invention. Figure 1 As shown, the cookware status recognition method is applied to the target cookware and may include the following operations:

[0132] S101. Obtain the first kitchenware information of the target cookware, and determine the second kitchenware information according to the first interaction signal sent by the target stove.

[0133] Specifically, the primary cookware information can be obtained through databases, IoT information cards or chips associated with the target cookware. The database can store primary cookware information about the target cookware itself, as well as information about cookware from the same batch or model. Correspondingly, this information can also be stored in IoT information cards or chips. The primary cookware information includes physical information about the target cookware, such as size, model, and material; it can also include performance-related information, such as cookware functions, production date, and usage duration. From this, the necessary data can be extracted to perform corresponding identification operations.

[0134] S102. Based on the first kitchenware information and the second kitchenware information, perform a kitchenware matching operation to obtain the result of the kitchenware matching operation;

[0135] S103. Determine the kitchenware status of the target cookware based on the result of the kitchenware matching operation;

[0136] Specifically, the cookware matching operation may include basic location matching, pairing via short-range communication methods such as Bluetooth, or determining the physical state and functional information of the current target cookware. See the subsequent implementation methods for details. Based on the result of the cookware matching operation, the cookware status of the target cookware in terms of location, physical condition, or function can be determined accordingly.

[0137] S104. Based on the state of the cookware and the result of the cookware matching operation, a second interaction signal is generated and sent to the target stove; wherein, the second interaction signal is used to trigger the target stove to perform an operation to determine and verify the state of the target cookware.

[0138] The target cookware and the target stove communicate via a first interaction signal and a second interaction signal, thereby allowing the extraction of relevant information from the other side for matching. The second interaction signal triggers the target stove to determine and verify the cookware status of the target cookware. On the target stove side, the cookware status of the target cookware can be further determined and verified, thus improving the accuracy of cookware status identification.

[0139] This embodiment determines the first kitchenware information of the target cookware and the second kitchenware information of the target stove, and can perform a kitchenware matching operation to obtain the current kitchenware status of the target cookware. It then generates a corresponding interactive signal and sends it to the target stove, thereby determining and verifying the kitchenware status of the target cookware on the target stove side. This improves the reliability and accuracy of kitchenware status recognition, and thus helps to improve the user experience of smart kitchenware.

[0140] In an optional embodiment, after determining the second kitchen appliance information based on the first interaction signal sent by the target stove, and before performing a kitchen appliance matching operation based on the first kitchen appliance information and the second kitchen appliance information to obtain the result of the kitchen appliance matching operation, the method further includes:

[0141] Based on the first kitchenware information, the first position information of the target pot is parsed, and based on the second kitchenware information, the second position information of the target stove is parsed;

[0142] And, the step of performing a kitchenware matching operation based on the first kitchenware information and the second kitchenware information to obtain the result of the kitchenware matching operation includes:

[0143] Based on the first location information and the second location information, perform a kitchenware matching operation to obtain a location matching result;

[0144] And, determining the cookware status of the target cookware based on the result of the cookware matching operation includes:

[0145] Based on the location matching result, the kitchenware position status of the target cookware is determined; wherein, the kitchenware position status includes a normal state or an off-center state, and is used to indicate whether the target cookware is located in a preset area on the target stove.

[0146] Position matching can determine the relative position between the target cookware and the target stove. It can perform two-dimensional position matching operations, and it can also perform three-dimensional position matching by obtaining the three-dimensional position information of the target cookware and the target stove. For example, by determining the current three-dimensional coordinates and pose information of the target cookware, it can be determined whether the target cookware is tilted or whether the target cookware is accurately placed.

[0147] As can be seen, this optional embodiment can parse the corresponding location information by using the first kitchenware information of the target cookware and the second kitchenware information of the target stove, and then perform location matching to determine whether the target cookware is located in the preset area on the target stove, thereby improving the reliability and accuracy of kitchenware status recognition and thus helping to improve the user experience of smart kitchenware.

[0148] In an optional embodiment, the step of performing a kitchenware matching operation based on the first location information and the second location information to obtain a location matching result includes:

[0149] Based on the first location information, a first matching range and at least one first matching point of the target cookware are determined; and based on the second location information, a second matching range and at least one second matching point of the target stove are determined.

[0150] Wherein, the first matching range is used to indicate the shape range of the target cookware; the second matching range is used to indicate the effective working range of the target stove.

[0151] Determine whether the first matching range exceeds the second matching range, and determine whether each of the first matching points meets the matching conditions indicated by each of the second matching points, to obtain the location matching result;

[0152] And, determining the cookware position status of the target cookware based on the position matching result includes:

[0153] If it is determined that the first matching range does not exceed the second matching range, and each of the first matching points meets the matching conditions indicated by each of the second matching points, then the cookware position status of the target cookware is determined to be normal; otherwise, the cookware position status of the target cookware is determined to be in a deviated state.

[0154] As can be seen, this optional embodiment determines whether the shape range of the target cookware is within the effective working range of the target stove by determining the first matching range and at least one first matching point of the target cookware, and the second matching range and at least one second matching point of the target stove, thereby determining the position matching result, improving the accuracy of cookware position status recognition, and further improving the reliability and accuracy of cookware status recognition, which in turn helps to improve the user experience of smart cookware.

[0155] In addition, since the target cookware may be larger than the target stove's preset area, the fact that the target cookware completely covers the second matching range of the target stove can also be used as a condition for judging that the cookware position of the target cookware is in a normal state. See the relevant information in the next embodiment.

[0156] In an optional embodiment, after determining the second matching range and at least one second matching point of the target stove based on the second location information, the method further includes:

[0157] Determine whether the area indicated by the first matching range is greater than the area indicated by the second matching range;

[0158] If it is determined that the area of ​​the region indicated by the first matching range is not greater than the area of ​​the region indicated by the second matching range, then the step of determining whether the first matching range exceeds the second matching range is triggered.

[0159] Furthermore, the method further includes:

[0160] If it is determined that the area indicated by the first matching range is larger than the area indicated by the second matching range, then it is determined whether the second matching range is completely covered by the first matching range.

[0161] If it is determined that the second matching range is completely covered by the first matching range, then the cookware position status of the target pot is determined to be normal; otherwise, the cookware position status of the target pot is determined to be off-center.

[0162] This implementation method can be combined with the relevant content of the previous implementation method. For example, the condition for determining that the kitchenware position of the target cookware is in a normal state may only include determining that the second matching range is completely covered by the first matching range, or it may only include determining that the first matching range does not exceed the second matching range, and that each of the first matching points meets the matching conditions indicated by each of the second matching points. Furthermore, when both conditions are met, the kitchenware position of the target cookware can also be determined to be in a normal state.

[0163] As can be seen, this optional embodiment determines whether the area indicated by the first matching range is greater than the area indicated by the second matching range, and executes different matching results based on the determination result. When the shape range of the target cookware is greater than the effective working range of the target stove, if the target cookware completely covers the effective working range of the target stove, it is also in a normal state. This covers a wider range of position matching conditions, improves the accuracy of cookware position status recognition, and thus improves the reliability and accuracy of cookware status recognition, which in turn helps to improve the user experience of smart cookware.

[0164] In an optional embodiment, the first matching point includes the geometric center and / or centroid of the bottom position of the target cookware;

[0165] Specifically, the first matching point reflects the structural information of the target cookware, which differs from the third matching point described later, which reflects the electromagnetic parameters of the target cookware. The first matching point is more intuitive in principle during position matching and can be combined with subsequent position matching based on the third matching point to improve accuracy; alternatively, it can be implemented independently.

[0166] The step of determining whether each of the first matching points meets the matching conditions indicated by each of the second matching points includes:

[0167] Determine the third position information of each of the first matching points;

[0168] Based on the preset first matching relationship and the third location information, determine the fourth location information of at least one first target point corresponding to each first matching point;

[0169] Wherein, the first matching relationship is used to indicate the positional mapping relationship between the first matching point and the corresponding first target point on the target stove;

[0170] Determine the fifth position information of each of the second matching points, and determine the first distance corresponding to each of the first matching points based on the fourth position information and the fifth position information;

[0171] Wherein, the first distance is used to indicate the distance between the theoretical position and the actual position of each first target point corresponding to each first matching point; the third position information, the fourth position information and the fifth position information are obtained based on the reference coordinate system determined by the target stove;

[0172] Specifically, the reference coordinate system can also be determined based on other smart devices. The reference coordinate system can be used to reflect the planar or spatial positional information of each smart kitchen appliance in the current target area. Correspondingly, the fourth positional information is the theoretical position, and the fifth positional information is the actual position.

[0173] If the first distance corresponding to each of the first matching points does not exceed a preset threshold, then it is determined that each of the first matching points meets the matching conditions indicated by each of the second matching points.

[0174] As can be seen, this optional embodiment determines the distance between the theoretical and actual positions of each of the first target points corresponding to each of the first matching points by using the geometric center and / or center of gravity of the bottom position of the target cookware, thereby identifying the position status of the cookware, improving the accuracy of the cookware position status identification, and thus improving the reliability and accuracy of the cookware status identification, which in turn helps to improve the user experience of smart cookware.

[0175] In an optional embodiment, after determining the second matching range and at least one second matching point of the target stove based on the second location information, the method further includes:

[0176] Based on the first kitchenware information, at least one third matching point is determined; all the third matching points include at least one electromagnetic parameter extreme point at the bottom of the target cookware;

[0177] Determine the sixth position information of each of the third matching points;

[0178] Based on the preset second matching relationship and the sixth position information, determine the seventh position information of at least one second target point corresponding to each of the third matching points;

[0179] Wherein, the second matching relationship is used to indicate the positional mapping relationship between the third matching point and the corresponding second target point on the target stove;

[0180] Determine the eighth position information of each of the second matching points, and determine the second distance corresponding to each of the third matching points based on the seventh position information and the eighth position information;

[0181] Wherein, the second distance is used to indicate the distance between the theoretical position and the actual position of each of the second target points corresponding to each of the third matching points; the sixth position information, the seventh position information and the eighth position information are obtained based on the reference coordinate system determined by the target stove;

[0182] If the second distance corresponding to each of the third matching points does not exceed the preset threshold, the kitchenware position of the target cookware is determined to be in a normal state; otherwise, the kitchenware position of the target cookware is determined to be in a deviated state.

[0183] As mentioned above, the third matching point is physical data that is different from the first matching point. The determined second matching point can be reused in both schemes. At the same time, this implementation can also determine a batch of fourth matching points to replace the function of the second matching point in the scheme.

[0184] As can be seen, this optional embodiment determines the electromagnetic parameter extreme point at at least one bottom position of the target cookware as the third matching point, and then determines the distance between the theoretical position and the actual position of each of the second target points corresponding to each of the third matching points according to the preset position matching relationship. This improves the accuracy of cookware position status recognition, thereby improving the reliability and accuracy of cookware status recognition, and thus helping to improve the user experience of smart cookware.

[0185] In an optional embodiment, determining at least one third matching point based on the first kitchenware information includes:

[0186] Based on the first kitchenware information, the historical data of electromagnetic parameter distribution at the bottom of the target pot is parsed out; and based on the historical data, at least one third matching point is determined.

[0187] And / or, based on the first cookware information, the scanning method parameters are parsed, and based on the scanning method parameters, the target cookware is scanned for electromagnetic parameters to obtain the electromagnetic parameter distribution results at the bottom of the cookware; and based on the electromagnetic parameter distribution results at the bottom of the cookware, at least one third matching point is determined.

[0188] Correspondingly, the process of determining the third matching point can also be applied to the process of obtaining physical information described in the subsequent implementation. Based on the relevant content recorded in the first kitchenware information, the electromagnetic parameters of the current target cookware can be scanned to obtain the corresponding electromagnetic parameter distribution results at the bottom of the cookware, thereby obtaining the third matching point. Alternatively, after receiving the corresponding signal, the first kitchenware information can be parsed to obtain historical data to determine the third matching point.

[0189] As can be seen, this optional embodiment can determine the corresponding third matching point by using historical or current data of the electromagnetic parameters at the bottom of the cookware, which can improve the accuracy of cookware position status recognition and thus improve the accuracy of cookware status recognition.

[0190] In an optional embodiment, this application also provides a kitchen appliance status recognition method applied to a target stove, the method comprising:

[0191] Obtain the second kitchen utensil information of the target stove;

[0192] Based on the second kitchenware information, a first interaction signal is generated and sent to the target cookware;

[0193] The system receives a second interaction signal from the target cookware and, based on the second interaction signal, parses the cookware status of the target cookware.

[0194] As can be seen, this optional embodiment obtains the second kitchenware information of the target stove, generates a corresponding first interaction signal, and sends the first interaction signal to the target pot, providing the target pot with the corresponding information from the target stove side. It also receives the second interaction signal from the target pot, parses the kitchenware status of the target pot, realizes the information interaction between the target stove and the target pot, thereby improving the intelligence and accuracy of kitchenware status recognition, which is conducive to improving the user experience of smart kitchenware.

[0195] In an optional embodiment, after receiving the second interaction signal from the target cookware and parsing the cookware status of the target cookware based on the second interaction signal, the method further includes:

[0196] Based on the second interaction signal, preset conditions are determined; wherein, the preset conditions are used to indicate the kitchen appliance parameter conditions that drive the target stove to work normally;

[0197] Determine whether the state of the kitchen utensils meets the preset conditions;

[0198] If it is determined that the condition of the kitchen appliance does not meet the preset conditions, then the heating function of the target stove appliance is disabled;

[0199] If it is determined that the state of the kitchenware meets the preset conditions, then the heating parameters of the target stove are adjusted according to the state of the kitchenware.

[0200] As can be seen, this optional embodiment can determine the kitchen appliance parameter conditions that drive the target stove to work normally through the second interactive signal, and then determine whether the current kitchen appliance status of the target cookware meets the corresponding preset conditions, so as to determine whether the heating function of the target stove needs to be turned off and whether the heating parameters of the target stove need to be adjusted. In this way, by improving the accuracy of kitchen appliance status recognition, the user experience of smart kitchen appliances is improved.

[0201] Example 2

[0202] Please see Figure 2 , Figure 2 This is a flowchart illustrating another method for identifying the state of kitchen utensils disclosed in an embodiment of the present invention. Figure 2 As shown, the kitchen utensil status recognition method may include the following operations:

[0205] S203. Based on the first kitchenware information, parse the physical information and functional information of the target cookware; wherein, the physical information is used to indicate the current physical parameter state of the target cookware; the functional information is used to indicate the preset cooking function of the target cookware;

[0206] Specifically, simply matching cookware based on its location and then identifying its condition may lead to inaccuracies and fail to achieve comprehensive identification of the target cookware. However, obtaining both the physical and functional information of the target cookware allows for accurate matching and can also detect aging issues, thereby improving safety during use.

[0207] S204. Based on the second kitchenware information, determine whether the physical information of the target cookware meets the preset working conditions, and obtain the physical matching result;

[0208] S205. Determine whether the functional information of the target cookware meets the functional requirements of the target stove, and obtain the functional matching result;

[0209] Steps S204 and S205 can be performed simultaneously, or they can be executed in the order that either step comes first.

[0210] S206. Determine the kitchenware performance status of the target cookware based on the physical matching result and the functional matching result;

[0211] Among them, the physical matching result is used to determine whether the physical state of the current target cookware meets the working requirements, and the functional matching result is used to determine whether the current target cookware is suitable for the corresponding target stove. It can also reflect whether the current target cookware meets the working requirements. Thus, matching can be performed from the performance level. Combined with the aforementioned implementation methods, the accuracy of cookware status recognition can be improved.

[0212] S207. Based on the state of the cookware and the result of the cookware matching operation, a second interaction signal is generated and sent to the target stove; wherein, the second interaction signal is used to trigger the target stove to perform an operation to determine and verify the state of the target cookware.

[0213] For a detailed description of S201, S202 and S207, please refer to the relevant descriptions of S101, S102 and S104 in Embodiment 1, which will not be repeated here.

[0214] This embodiment determines the current physical parameters and preset cooking functions of the target cookware, and determines the cookware performance status of the target cookware based on the physical matching results and function matching results. By matching cookware from the perspective of cookware performance, the reliability and accuracy of cookware status recognition are improved, which in turn helps to improve the user experience of smart cookware.

[0215] In an optional embodiment, parsing the physical information of the target cookware based on the first cookware information includes:

[0216] Based on the first kitchenware information, at least one target parameter of the target cookware is determined;

[0217] The target parameters include: cookware shape, cookware electrical conductivity, cookware magnetic permeability, and cookware temperature;

[0218] The parameter distribution of each of the target parameters on the target cookware is obtained, and the physical information of the target cookware is determined based on the parameter distribution.

[0219] Specifically, the physical information can include current physical information. By determining the corresponding scanning method parameters, electromagnetic scanning is performed on the current target cookware to obtain the corresponding information. Alternatively, after receiving the corresponding signal, the most recent historical physical information can be obtained from the database. The acquisition of the parameter distribution of each target parameter on the target cookware can be implemented in conjunction with the relevant implementation methods in the previous embodiment.

[0220] As can be seen, this optional embodiment can determine the corresponding physical information by determining the distribution of parameters such as the shape, conductivity, magnetic permeability, or temperature of the target cookware, which can improve the accuracy of physical matching of cookware, thereby improving the reliability and accuracy of cookware status recognition and enhancing the user experience of smart cookware.

[0224] The kitchenware matching module 32 is used to perform a kitchenware matching operation based on the first kitchenware information and the second kitchenware information, and obtain the result of the kitchenware matching operation;

[0225] The kitchenware status determination module 33 is used to determine the kitchenware status of the target cookware based on the result of the kitchenware matching operation.

[0226] The information interaction module 34 is used to generate a second interaction signal based on the status of the cookware and the result of the cookware matching operation, and send the second interaction signal to the target stove; wherein, the second interaction signal is used to trigger the target stove to perform an operation to determine and verify the status of the target cookware.

[0227] This embodiment determines the first kitchenware information of the target cookware and the second kitchenware information of the target stove, and can perform a kitchenware matching operation to obtain the current kitchenware status of the target cookware. It then generates a corresponding interactive signal and sends it to the target stove, thereby determining and verifying the kitchenware status of the target cookware on the target stove side. This improves the reliability and accuracy of kitchenware status recognition, and thus helps to improve the user experience of smart kitchenware.

[0228] In an optional embodiment, please refer to Figure 4 , Figure 4 This is a schematic diagram of the structure of a kitchen utensil status recognition device disclosed in an embodiment of the present invention. Figure 4 As shown, the device further includes:

[0232] And, the specific method by which the cookware status determination module 33 determines the cookware status of the target cookware based on the result of the cookware matching operation includes:

[0233] Based on the location matching result, the kitchenware position status of the target cookware is determined; wherein, the kitchenware position status includes a normal state or an off-center state, and is used to indicate whether the target cookware is located in a preset area on the target stove.

[0234] As can be seen, this optional embodiment can parse the corresponding location information by using the first kitchenware information of the target cookware and the second kitchenware information of the target stove, and then perform location matching to determine whether the target cookware is located in the preset area on the target stove, thereby improving the reliability and accuracy of kitchenware status recognition and thus helping to improve the user experience of smart kitchenware.

[0235] In an optional embodiment, the kitchenware matching module 32 performs a kitchenware matching operation based on the first location information and the second location information, and the specific method for obtaining the location matching result includes:

[0236] Based on the first location information, a first matching range and at least one first matching point of the target cookware are determined; and based on the second location information, a second matching range and at least one second matching point of the target stove are determined.

[0237] Wherein, the first matching range is used to indicate the shape range of the target cookware; the second matching range is used to indicate the effective working range of the target stove.

[0238] Determine whether the first matching range exceeds the second matching range, and determine whether each of the first matching points meets the matching conditions indicated by each of the second matching points, to obtain the location matching result;

[0239] And, the specific method by which the cookware status determination module 33 determines the cookware position status of the target cookware based on the position matching result includes:

[0240] If it is determined that the first matching range does not exceed the second matching range, and each of the first matching points meets the matching conditions indicated by each of the second matching points, then the cookware position status of the target cookware is determined to be normal; otherwise, the cookware position status of the target cookware is determined to be in a deviated state.

[0241] As can be seen, this optional embodiment determines whether the shape range of the target cookware is within the effective working range of the target stove by determining the first matching range and at least one first matching point of the target cookware, and the second matching range and at least one second matching point of the target stove, thereby determining the position matching result, improving the accuracy of cookware position status recognition, and further improving the reliability and accuracy of cookware status recognition, which in turn helps to improve the user experience of smart cookware.

[0242] In one alternative embodiment, such as Figure 4 As shown, the device further includes:

[0244] Determine whether the area indicated by the first matching range is greater than the area indicated by the second matching range;

[0245] If it is determined that the area indicated by the first matching range is not greater than the area indicated by the second matching range, then the kitchenware matching module is triggered to determine whether the first matching range exceeds the second matching range.

[0246] In addition, the kitchen utensil status determination module 33 is also used for:

[0247] If it is determined that the area indicated by the first matching range is larger than the area indicated by the second matching range, then it is determined whether the second matching range is completely covered by the first matching range.

[0248] If it is determined that the second matching range is completely covered by the first matching range, then the cookware position status of the target pot is determined to be normal; otherwise, the cookware position status of the target pot is determined to be off-center.

[0249] As can be seen, this optional embodiment determines whether the area indicated by the first matching range is greater than the area indicated by the second matching range, and executes different matching results based on the determination result. When the shape range of the target cookware is greater than the effective working range of the target stove, if the target cookware completely covers the effective working range of the target stove, it is also in a normal state. This covers a wider range of position matching conditions, improves the accuracy of cookware position status recognition, and thus improves the reliability and accuracy of cookware status recognition, which in turn helps to improve the user experience of smart cookware.

[0250] In an optional embodiment, the first matching point includes the geometric center and / or centroid of the bottom position of the target cookware;

[0257] If the first distance corresponding to each of the first matching points does not exceed a preset threshold, then it is determined that each of the first matching points meets the matching conditions indicated by each of the second matching points.

[0258] As can be seen, this optional embodiment determines the distance between the theoretical and actual positions of each of the first target points corresponding to each of the first matching points by using the geometric center and / or center of gravity of the bottom position of the target cookware, thereby identifying the position status of the cookware, improving the accuracy of the cookware position status identification, and thus improving the reliability and accuracy of the cookware status identification, which in turn helps to improve the user experience of smart cookware.

[0266] If the second distance corresponding to each of the third matching points does not exceed the preset threshold, the kitchenware position of the target cookware is determined to be in a normal state; otherwise, the kitchenware position of the target cookware is determined to be in a deviated state.

[0267] As can be seen, this optional embodiment determines the electromagnetic parameter extreme point at at least one bottom position of the target cookware as the third matching point, and then determines the distance between the theoretical position and the actual position of each of the second target points corresponding to each of the third matching points according to the preset position matching relationship. This improves the accuracy of cookware position status recognition, thereby improving the reliability and accuracy of cookware status recognition, and thus helping to improve the user experience of smart cookware.

[0268] In an optional embodiment, the kitchenware status determination module 33 determines at least one third matching point based on the first kitchenware information in the following manner:

[0277] And, the specific method by which the cookware status determination module 33 determines the cookware status of the target cookware based on the result of the cookware matching operation includes:

[0278] Based on the physical matching result and the functional matching result, the cookware performance status of the target cookware is determined; the cookware performance status is used to indicate whether the current physical parameters of the target cookware can normally perform the preset cooking function.

[0279] As can be seen, this optional embodiment determines the current physical parameter state and preset cooking function of the target cookware, and determines the cookware performance state of the target cookware based on the physical matching result and the function matching result. It performs cookware matching from the perspective of cookware performance, which improves the reliability and accuracy of cookware state recognition, and thus helps to improve the user experience of smart cookware.

[0280] In an optional embodiment, the second information parsing module 37 parses the physical information of the target cookware based on the first cookware information in a specific manner, including:
