[0039] To make the objectives, technical solutions and advantages of the present invention clearer, the following will, in combination with the accompanying drawings in the embodiments of the present invention, completely describe the technical solutions of the present invention through specific implementation manners. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment

[0041] The embodiment of the present invention provides a detection method for preventing misoperation of an intelligent cooking utensil. In intelligent cooking, this detection method can determine whether the cooking utensil is in the correct hob position by detecting the temperature change curve at the bottom of the pot. Among them, the cooking appliance can be a household cooking appliance with two hobs or a cooking appliance with multiple hobs. Figure 1 is a schematic structural diagram of a household cooking appliance provided by an embodiment of the present invention; Figure 2 is a schematic structural diagram of a household cooking appliance and a cooking utensil provided by an embodiment of the present invention; Figure 3 is a schematic flow chart of a detection method for preventing misoperation of an intelligent cooking utensil provided by the present invention. Combining Figures 1 - 3 as shown, the detection method for preventing misoperation of the intelligent cooking utensil provided by the embodiment of the present invention includes:

[0042] S11. Determine the firing states of the respective hobs of the cooking appliance.

[0043] Specifically, as Figure 1 shown in, the cooking appliance 1 includes a left hob 21 and a right hob 22. Combining Figure 2 as shown, the cooking utensil 3 can be placed on the left hob 21. In intelligent cooking, the control system of the intelligent cooking utensil 3 provided by the embodiment of the present invention can detect the temperature at the bottom of the pot through a temperature sensor, perform data interaction with the cooking appliance 1 in a wireless communication manner, and actively obtain the ignition states of the respective hobs of the cooking appliance 1, so as to determine the firing states of the respective hobs of the cooking appliance 1. In this solution, the existing temperature sensor in the cooking utensil 3 is utilized, and there is no need to additionally increase temperature detection equipment, which is beneficial to controlling production costs.

[0044] S12. When at least one hob is in the firing state, determine the fire power level of the fired hob.

[0045] Combining Figure 2 as shown, the left hob 21 and the right hob 22 of the cooking utensil in the present invention are respectively pre-set with corresponding cooking utensils, and there is a one-to-one binding relationship between the cooking utensil and the hob of the cooking appliance. For example, Figure 2In the application scenario, the cookware 3 is placed on the left burner 21 of the cooktop, but the burner of the cookware 3 is actually bound to the right burner 22. In intelligent cooking, the cooktop 1 needs to identify which burner the cookware 3 is placed on for seamless interaction with the user, so as to remind the user whether the burner is placed incorrectly, or when the user actively places the cookware on the burner, the cooktop can automatically adjust the firepower of that burner.

[0046] When the cooktop 1 starts the cooking program, the firepower level of the cookware burner is adjusted manually or automatically. The firepower levels include 8 levels from 0 to 7 in increasing order, and any of the 8 firepower levels can be adjusted. When the firepower level is from 1 to 7, the burner is in the firing state. The control system of the cooktop 1 detects that the left burner 21 and / or the right burner 22 of the cooktop 1 is in the firing state, and determines the firing burner as the burner to be used for cooking. Here, the firing burner refers to the burner to be used for cooking. When the left burner 21 is in the firing state, the left burner 21 is the firing burner, and the firepower level of the left burner 21 is confirmed; when the right burner 22 is in the firing state, the right burner 22 is the firing burner, and the firepower level of the right burner 22 is confirmed; when both the left burner 21 and the right burner 22 are in the firing state, both the left burner 21 and the right burner 22 are firing burners, and the firepower levels of the left burner 21 and the right burner 22 are confirmed. It should be noted that when both the left burner 21 and the right burner 22 are firing burners, their firepower levels are different.

[0047] S13. According to the firepower level of the firing burner, retrieve the theoretical temperature curve of the cookware corresponding to the firepower level of the stored firing burner.

[0048] S14. While the firing burner is in the firing state, record the actual temperature curve of the target cookware.

[0049] Combined Figure 1 and Figure 2 As shown, since it is uncertain which burner of the cooktop the cookware matching the firing burner is on, when the firing burner is in the firing state, the control system of the target cookware 3 activates the temperature sensor of the target cookware 3 to record the temperature value at the bottom of the cookware, and obtains the actual temperature curve of the target cookware; if the firepower level of the firing burner is the 5th firepower level, according to the fact that the firing burner is at the 5th firepower level at this time, the theoretical temperature curve of the cookware corresponding to the 5th firepower level of the firing burner stored inside the target cookware 3 is retrieved simultaneously.

[0050] It should be noted that steps S13 and S14 are carried out simultaneously.

[0051] S15. According to the comparison result between the actual temperature curve and the theoretical temperature curve, determine whether the target cookware is placed on the firing burner.

[0052] Further, the control system compares the actual temperature curve of the cooktop corresponding to the ignited burner at the 5-level firepower setting with the theoretical temperature curve. For example, it fits the actual temperature curve and the theoretical temperature curve, compares the temperature values, etc. According to parameters such as the similarity of the curve fitting, it determines whether the cooktop corresponding to the ignited burner is on the ignited burner. After the cooktop detects that one of the left and right burners of the cooktop is ignited, the target cookware 3 conducts data interaction with the cooktop 1 through wireless communication. The target cookware 3 automatically obtains the firepower setting of the burner and simultaneously detects the temperature of the bottom of the pot. According to the temperature curve of the bottom of the pot, it judges the position where the cookware is placed on the burner, and reminds the user whether the burner is placed incorrectly, which can avoid safety problems caused by actively turning on the cooktop burner.

[0053] In summary, the intelligent cookware anti-fool detection method provided by the invention embodiment, by pre-judging the ignition state of the cooktop burner, actively obtaining the firepower setting of the ignited burner, according to the firepower setting of the ignited burner, retrieving the theoretical temperature curve of the cookware corresponding to the firepower setting of the ignited burner stored, while changing the firepower setting of the ignited burner, using the temperature sensor of the cookware itself to record the actual temperature curve of the target cookware, can effectively save manufacturing costs; through the comparative analysis of the actual temperature curve and the theoretical temperature curve, using the temperature change curve of the bottom of the pot to determine whether the target cookware is placed on the ignited burner, identifying the position of the burner where the cookware is placed, so as to conduct a non-intrusive interaction with the user, reminding the user whether the burner is placed incorrectly, which can avoid safety problems caused by actively turning on the cooktop burner and improve the application performance of intelligent cookware.

[0054] Figure 4 FIG. is a schematic flow chart of another intelligent cookware anti-fool detection method provided by the present invention. On the basis of the above embodiment, in combination with Figure 1 、 Figure 2 and Figure 4 shown, the invention embodiment also provides an intelligent cookware anti-fool detection method, and this detection method includes:

[0055] S21. Judge the ignition state of each burner of the cooktop.

[0056] Refer to step S11 in the above embodiment.

[0057] S22. When at least one burner is in the ignition state, determine the firepower setting of the ignited burner.

[0058] Refer to step S12 in the above embodiment.

[0059] S23. According to the firepower setting of the ignited burner, retrieve the theoretical temperature curve of the cookware corresponding to the firepower setting of the ignited burner stored.

[0060] Refer to step S13 in the above embodiment.

[0061] S24. While the open burner is in the firing state, record the actual temperature curve of the target cookware.

[0062] Continue to refer to Figures 1 - 4 As shown, when the left burner 21 and / or the right burner 22 of the cooktop 1 is in the firing state, the control system of the cookware 3 exchanges data with the cooktop 1 to determine that the firepower level of the same open burner is a fixed level. In a feasible method for obtaining the actual temperature curve of the target cookware, while the open burner is in the firing state, start the temperature sensor of the target cookware to record the actual temperature curve of the bottom of the cookware at the firepower levels of each open burner.

[0063] Optionally, when the target cookware determines that the firepower level of the same open burner is a fixed level, within the first time period, record the actual temperature value of the target cookware every second time period. According to the actual temperature value and its corresponding time point, obtain the actual temperature curve of the target cookware at the firepower levels of each open burner; where the second time period is less than the first time period.

[0064] For example, in an application scenario, when only the left burner 21 is firing, identify the burner position where the cookware is placed. The user only Figure 2 In the scenario, the left burner 21 of the cooktop is fired, and the gear knob of the left burner 21 is turned to the 5th gear firepower level and recorded as ML5, and the gear knob of the right burner 22 is turned to the 0th gear firepower level, that is, the right burner 22 is turned off. The firepower level of the left burner 21 is a fixed level, and the temperature sensor of the corresponding cookware records the actual temperature value of the target cookware every N seconds within T seconds. According to the actual temperature value and its corresponding time point, the actual temperature curve of the cookware corresponding to the left burner 21 at the firepower levels of each open burner is obtained.

[0065] S25. Compare the actual temperature curve with the theoretical temperature curve to obtain the similarity between the actual temperature curve and the theoretical temperature curve.

[0066] Specifically, the similarity refers to the degree of similarity between the actual temperature curve of the target cookware and the theoretical temperature curve of the cookware corresponding to the firepower level of the open burner that has been stored. When the target cookware is placed on the open burner, the similarity is the largest.

[0067] S26. Compare the size of the similarity with the similarity threshold. When the similarity is greater than or equal to the similarity threshold, determine that the target cookware is placed on the open burner.

[0068] Specifically, the control system of the cookware determines that the target cookware is placed on the open burner by comparing the size of the similarity with the similarity threshold; when the similarity is less than the similarity threshold, determine that the target cookware is not placed on the open burner.

[0069] The following is combined withFigure 2 As shown below, some specific application scenarios are enumerated to explain the detection method for preventing misoperation of the intelligent cookware provided by the embodiments of the present invention.

[0070] Figure 5 It is a schematic logic flow diagram of the detection method for preventing misoperation of the intelligent cookware in an application scenario provided by the present invention; Figure 6 For Figure 5 it is a schematic diagram of the actual temperature curve and the theoretical temperature curve in the shown scenario. Combining Figures 1 - 6 As shown, in Application Scenario 1, when it is determined that at least two burners are in the firing state, it is identified whether the position of the cookware placed on the burners is correct. The detection method for preventing misoperation of the intelligent cookware in this application scenario is as follows:

[0071] S100. When the user Figure 2 both the left and right burners of the cooktop in the scenario are firing, turn the gear knob of the left burner 21 of the cooktop to the 5th gear, denoted as ML5; turn the gear knob of the right burner 22 to the 3rd gear, denoted as MR3.

[0072] Specifically, when both the left and right burners are firing and both are firing burners, it is identified whether the target cookware is placed on the left burner 21 or the right burner 22.

[0073] S101. Determine whether the left and right burners of the cooktop are firing.

[0074] S102. After the cookware detects that the left burner of the cooktop is firing, query and record the current fire power gear of the left burner every N seconds, and record the temperature of the cookware for a continuous period of T seconds to obtain the actual temperature curve L - L1 of the cookware within T seconds of the left burner firing.

[0075] S103. After the cookware detects that the right burner of the cooktop is firing, query and record the current fire power gear of the right burner every N seconds, and record the temperature of the cookware for a continuous period of T seconds to obtain the actual temperature curve R - L1 of the cookware within T seconds of the right burner firing.

[0076] It should be noted that, combining Figure 2 in the application scenario, one cookware corresponds to two firing burners, and the actual temperature curve L - L1 of the cookware and the actual temperature curve R - L1 of the cookware are the same actual temperature curve L1, as Figure 6 shown.

[0077] Furthermore, optionally, the actual temperature curve of the target cookware is respectively compared with the theoretical temperature curves of the cookware corresponding to the fire power gears of each stored firing burner to obtain the similarity between the actual temperature curve and the theoretical temperature curve of each firing burner.

[0078] S104. Compare the L-L1 with the theoretical temperature curves L8-5 from zero gear (M0) to 5th gear (M5) in the internal database of the cookware to obtain the similarity L-T1 between L-L1 and L8-5, as Figure 6 shown.

[0079] Exemplarily, the similarity L-T1 is 0.85.

[0080] S105. Compare the R-L1 with the theoretical temperature curves L8-3 from zero gear (M0) to 3rd gear (M3) in the internal database of the cookware to obtain the similarity R-T1 between R-L1 and L8-3, as shown in Figure 6 shown.

[0081] Exemplarily, the similarity L-T1 is 0.65.

[0082] Further, obtain the maximum value among the similarities, take the maximum similarity value as the final similarity, compare the size of the final similarity with the similarity threshold. When the final similarity is greater than or equal to the similarity threshold, determine that the cookware is set at the position of the ignition hob corresponding to the maximum similarity value.

[0083] S106. Judge the maximum value between L-T1 and R-T1, take the maximum value as the final similarity, and judge whether the final similarity is greater than the similarity threshold.

[0084] S107. If the maximum value is less than the similarity threshold, that is, no, then determine that the cookware is not placed on the left or right hob of the cooker.

[0085] Specifically, L-T1 (0.85) > R-T1 (0.65), L-T1 (0.85) is the final similarity. If L-T1 (0.85) is less than the similarity threshold, determine that the cookware is not placed on the left hob 21 of the cooker to remind the user that the position of the cookware is placed incorrectly.

[0086] S108. If the maximum value is greater than or equal to the similarity threshold, that is, yes, then determine that the pot is placed on the hob corresponding to the final similarity.

[0087] Specifically, if L-T1 (0.85) is greater than or equal to the similarity threshold, then determine that the cookware is placed on the left hob 21 corresponding to the final similarity.

[0088] After the embodiment of the present invention detects that one of the left and right burners of the cooking appliance is ignited, it automatically obtains the burner's gear position. After the gear position changes, the cooking appliance automatically adjusts the burner's firepower, and at the same time detects the temperature of the bottom of the pot, obtains the similarity between the actual temperature curve and the theoretical temperature curve of each ignited burner, compares the size of the similarity with the similarity threshold, and judges the position of the burner where the target pot is placed, which can remind the user whether the burner is placed incorrectly, so that the user can actively place the burner, and can avoid safety problems caused by actively turning on the cooking appliance burner, realizing intelligent anti-fool detection of the pot.

[0089] Figure 7 It is a schematic diagram of the logic flow of a detection method for intelligent anti-fool of a pot in an application scenario provided by the present invention; Figure 8 is Figure 7 A schematic diagram of the actual temperature curve and the theoretical temperature curve in the shown scenario. Combining Figures 1 - 4 、 Figures 7 - 8 As shown, in Application Scenario 2, when only the left burner 21 is ignited, it is identified whether the pot corresponding to the left burner 21 is placed on the left burner 21. The detection method for intelligent anti-fool of the pot in this application scenario is as follows:

[0090] S201. The user only ignites the left burner of the cooking appliance in Figure 2 the scenario and turns the gear knob of the left burner of the cooking appliance to the 5th gear, denoted as ML5; the gear knob of the right burner is turned to the MR0 gear, that is, the right burner is turned off.

[0091] Specifically, the left burner 21 is in the ignited state, and the left burner 21 is the ignited burner.

[0092] S202. After the pot detects that the left burner of the cooking appliance is ignited, it queries and records the current firepower gear of the left burner every N seconds, and continuously records the temperature of the pot for T seconds to obtain the actual temperature curve L2 of the pot within T seconds after the left burner is ignited, as Figure 8 shown.

[0093] S203. Compare L2 with the theoretical temperature curves L8-5 from zero gear to 5th gear (M5) in the internal database of the pot to obtain the similarity L-T2 between L2 and L8-5, as Figure 8 shown.

[0094] Exemplarily, the similarity L-T1 is 0.85.

[0095] S204. Judge whether the value of L-T2 is greater than or equal to the similarity threshold.

[0096] S205. If L-T2 is less than the similarity threshold, that is, no, it is determined that the pot is not placed on the left burner of the cooking appliance.

[0097] Specifically, as Figure 2In the application scenario, the cookware 3 is not placed on the right burner bound to it, so as to remind the user that the placement position of the cookware is incorrect.

[0098] S206. If L-T2 is greater than or equal to the similarity threshold, that is, yes, it is determined that the cookware is placed on the left burner of the cooking appliance.

[0099] Specifically, as Figure 2 In the application scenario, the cooking appliance includes left and right burners, and the cookware 3 is placed on the left burner 21.

[0100] Figure 9 It is a schematic diagram of the logical flow of a detection method for preventing misoperation of an intelligent cookware in an application scenario provided by the present invention; Figure 10 It is Figure 9 A schematic diagram of the actual temperature curve and the theoretical temperature curve in the shown scenario. Combining Figures 1 - 4 、 Figures 9 - 10 As shown in, in Application Scenario 3, when only the right burner 22 is fired, it is identified whether the cookware corresponding to the right burner 22 is placed on the right burner 22. The detection method for preventing misoperation of the intelligent cookware in this application scenario is as follows:

[0101] S301. When the user only fires the right burner of the cooking appliance in the Figure 2 scenario and turns the gear knob of the right burner of the cooking appliance to gear 3, denoted as MR3, and turns the gear knob of the left burner to ML0 gear, that is, the left burner is turned off.

[0102] Specifically, the right burner 22 is in the firing state, and the right burner 22 is the fired burner.

[0103] S302. After the cookware detects that the right burner of the cooking appliance is fired, it queries and records the current fire gear of the right burner every N seconds, and continuously records the temperature of the cookware for T seconds to obtain the actual temperature curve L3 of the cookware within T seconds of the right burner firing, as Figure 10 shown.

[0104] S303. Compare L3 with the theoretical temperature curve L8-3 from zero gear to gear 3 (M3) in the internal database of the cookware to obtain the similarity R-T2 (0.15) between L3 and L8-3, as Figure 10 shown.

[0105] Exemplarily, the similarity L-T1 is 0.15.

[0106] S304. Determine whether the value of R-T2 is greater than or equal to the similarity threshold.

[0107] S305. If R-T2 is less than the similarity threshold, that is, no, it is determined that the cookware is not placed on the right burner of the cooking appliance. To remind the user that the placement position of the cookware is incorrect.

[0108] S306. If R - T2 is greater than or equal to the similarity threshold, that is, if it is "yes", it is determined that the cookware is placed on the right burner of the cooking appliance.

[0109] In the above embodiment, in step S24, in a feasible way to obtain the actual temperature curve of the target cookware, while the burner is in the firing state, start the temperature sensor of the target cookware to record the actual temperature curve at the bottom of the cookware under all firepower levels of the same burner.

[0110] Optionally, the target cookware determines that the firepower levels of the same burner include multiple firepower levels. Record the actual temperature value of the target cookware every second time during the duration of each firepower level, and obtain the sum of the actual temperature curves of the target cookware within each firepower level; at the same time, the firepower levels of different burners are different, and the total duration of all firepower levels of the same burner is the first time.

[0111] On the basis of application scenario one, when both the left and right burners are firing, add specific control of the cooking appliance's gear before the cooking appliance works normally, and judge the position of the burner where the target cookware is located through the temperature curve during the specific control. The specific embodiment is as follows.

[0112] Figure 10 This is a schematic logic flow diagram of a detection method for preventing misoperation of an intelligent cookware in an application scenario provided by the present invention. Combining Figures 1 - 4 、 Figures 9 - 10 As shown, in application scenario four, when both the left and right burners are firing, identify whether the position of the burner where the cookware is placed is correct. The detection method for preventing misoperation of the intelligent cookware in this application scenario is as follows:

[0113] S401. As Figure 2 In the application scenario, when the user manually turns on a certain burner, the cookware queries whether the cooking appliance burner is ignited. If it is, the temperature sensor of the cookware starts to record the actual temperature curve of the cookware at this time.

[0114] S402. If the burner is firing, manually adjust the gears of the left burner and / or the right burner respectively, adjust the gear of the cooking appliance burner to the set gear S1 and maintain it for N seconds, and record the temperature curve.

[0115] Specifically, adjust the gear of the left burner 21 to the set gear SL1 and maintain it for N seconds, and / or adjust the gear of the right burner to the set gear SR1 and maintain it for N seconds, and record the actual temperature curve of the cookware within N seconds.

[0116] It should be noted that to distinguish the gear changes of the left and right burners, at the same time, if both the left burner 21 and the right burner 22 are firing, the set gear SL1 of the left burner 21 and the set gear SR1 of the right burner 22 are different.

[0117] S403. Adjust the cooking hob burner to the set position and maintain it for M seconds, and record the temperature curve.

[0118] Specifically, after adjusting the left burner 21 to the set position SL1, adjust the left burner 21 to the set position SL2 and maintain it for M seconds, and record the actual temperature curve of the cookware within M seconds; and / or, after adjusting the right burner to the set position SR1, adjust the right burner to the set position SR2 and maintain it for M seconds, and record the actual temperature curve of the cookware within M seconds.

[0119] It should be noted that to distinguish the position changes of the left and right burners, within the same time, the set positions SL2 of the left burner 21 and the set position SR2 of the right burner 22 are different.

[0120] S404. Adjust the cooking hob burner to the user-set position.

[0121] Specifically, after adjusting the left burner 21 to the set position SL2, adjust the left burner 21 to the user-set position respectively; and / or, after adjusting the right burner to the set position SR2, adjust the left and right burners to the user-set position. It should be noted that to distinguish the position changes of the left and right burners, within the same time, the set positions of the left burner 21 and the right burner 22 are different.

[0122] S405. Obtain the actual temperature curve record L4 of the cookware during the position change time of the left and right burners.

[0123] S406.

[0125] S408. When both the left and right burners are in the on state, select the maximum value between the similarity L-T4 and the similarity R-T4, and use the maximum similarity value as the final similarity.

[0126] S409. If the final similarity is greater than or equal to the similarity threshold, it is determined that the cookware is located on the burner corresponding to the final similarity.

[0127] Before the cooking appliance works normally, the present invention performs specific control on the cooking appliance gears. When multiple burners are ignited, the active control is used to set the gears of the ignited burners to multiple gears. During the duration of the multiple gears, the actual temperature curve of the cookware is continued. The actual temperature curve of the cookware is respectively compared with the theoretical temperature curves of the multiple ignited burners. According to the maximum similarity value, the specific position of the cookware on the burner can be determined, which can improve the accuracy of the cookware placement position.

[0128] Based on the above embodiments, before step 203, the detection method further includes:

[0129] Recording the theoretical temperature curve. Among them, the theoretical temperature curve is obtained in the pre-experiment process. According to the corresponding relationship between the cookware and the burner, the cookware is set on the determined ignited burner. At different heating power gears, within the first time period, the theoretical temperature values of the cookware are recorded every second time period, and according to the theoretical temperature values and their corresponding time points, the theoretical temperature curve of the cookware is obtained.

[0130] Storing the theoretical temperature curves of the cookware corresponding to the ignited burners at different heating power gears.

[0131] Specifically, the acquisition method of the theoretical temperature curve is the same as that of the actual temperature curve. In the pre-experiment process, the intelligent cookware is placed on its corresponding burner to ensure that the initial temperature of the intelligent cookware is the same. The burner is set to any one of the 1-8 gear heating power gears. During the duration of the heating power gear, the intelligent cookware records the theoretical temperature value of the cookware every N seconds for a continuous T seconds. The time interval between each theoretical temperature value is N seconds, forming a theoretical temperature curve L0 of S(T / N) data points.

[0132] The theoretical temperature curves L0 of the cookware corresponding to the 1-8 gear heating power gears of the burner are obtained in sequence and the 8 theoretical temperature curves L0 are stored in the database of the cookware.

[0133] Figure 12 It is a schematic flow chart of curve similarity judgment provided by the present invention. A feasible implementation manner, in combination with Figure 4 and Figure 12 shown, the acquisition method of the actual temperature curve is the same as the acquisition time and acquisition interval of the theoretical temperature curve. The actual temperature curve is formed by the intelligent cookware recording once every N seconds for a continuous T seconds, with S(T / N) data. The time interval between each actual temperature value is N seconds. The total number of theoretical temperature values is S. Step 205 includes:

[0134] S501. Calculate the difference between each actual temperature value in the actual temperature curve and the theoretical temperature value with the same acquisition order in the theoretical temperature curve.

[0135] For example, in combination with Application Scenario 4, record the difference between the actual temperature curve L4 and the theoretical temperature values with the same acquisition order in the theoretical temperature curve R-L0 of the right burner head.

[0136] S502. Compare the magnitudes of each difference with the first difference threshold to obtain the total number M of differences less than or equal to the first difference threshold.

[0137] Specifically, the magnitude of the first difference threshold is not specifically limited here and can be flexibly set.

[0138] S503. Determine the similarity T (M / S) between the actual temperature curve and the theoretical temperature curve based on the ratio of the total number M to the total number S of theoretical temperature values.

[0139] Figure 13 This is another schematic flowchart for judging the similarity of curves provided by the present invention. A feasible implementation manner, in combination with Figure 4 As shown, the actual temperature curve is formed by recording once every N seconds for T seconds in the intelligent cooker, resulting in S (T / N) data. The time interval between each actual temperature value is N seconds. The total number of theoretical temperature values is S. It is known that there are multiple time periods Tn (N seconds) with different slopes in the theoretical temperature curve L0 in the database, and there are a total of S time periods. The sum of all Tn time periods is T seconds, that is, T = Tn * S. The theoretical curve slope of the theoretical temperature curve L0 in the Tn time period is Kn. Step 205 includes:

[0140] S601. Calculate the difference between the actual curve slope within each second time in the actual temperature curve and the theoretical curve slope within the same acquisition order of the second time in the theoretical temperature curve.

[0141] For example, in combination with Application Scenario 4, calculate the difference Ks between the actual curve slope K1 within the Tn time period in the actual temperature curve L4 recorded by the cooker and the theoretical curve slope Kn within the same acquisition order in the Tn time period of the theoretical temperature curve R-L0 of the right burner head.

[0142] Obtain S differences Ks in sequence.

[0143] S602. Compare the magnitudes of each difference with the second difference threshold to obtain the total number M of differences less than or equal to the second difference threshold.

[0144] Judge whether the S differences Ks exceed the second difference threshold, and record the total amount M of the differences Ks that do not exceed the second difference threshold, that is, the number M of the time periods Tn. Among them, the magnitude of the second difference threshold is not specifically limited here and can be flexibly set.

[0145] S603. If the difference does not exceed the second difference threshold, increment the number of M by one, and repeat step 602 until all time periods are calculated.

[0146] S604. Determine the similarity T (M / S) between the actual temperature curve and the theoretical temperature curve according to the ratio of the total quantity M to the total number of time periods S in the second time period.

[0147] Figure 14 This is a schematic flow chart for judging the similarity of another curve provided by the present invention. A feasible implementation manner, in combination with Figure 4 and Figure 13 As shown, the acquisition method of the actual temperature curve is the same as the acquisition time and acquisition interval of the theoretical temperature curve. The actual temperature curve is recorded by the intelligent cooker every N seconds, and a total of C data are recorded. The C data are divided into S segments of data, and the time of each segment of data is T. The integral An of the temperature and time within the T time period is calculated. A feasible implementation manner, in combination with Figure 4 As shown, step 205 includes:

[0148] S701. Divide the actual temperature curve L4 into S segments of data.

[0149] Specifically, divide the actual temperature curve into multiple sub-actual temperature curves according to the acquisition order of the actual temperature values; divide the theoretical temperature curve into multiple sub-theoretical temperature curves according to the acquisition order of the theoretical temperature values; the number of actual temperature values within the sub-actual temperature curve is the same as the number of theoretical temperature values within the sub-theoretical temperature curve.

[0150] For example, the intelligent cooker records once every 1 second, and 100 (T / N) data are formed in 100 seconds. For example, in combination with application scenario four, divide the actual temperature curve of the intelligent cooker into one actual temperature curve for every 10 temperature values, and divide the theoretical temperature curve of the intelligent cooker into one theoretical temperature curve for every 10 temperature values, obtaining 10 segments of data, and the time of each segment of data is 10 seconds.

[0151] S702. Calculate the integral A1 of each segment of the temperature curve and time T, and calculate the integral difference As between each actual integral quantity A1 and its corresponding theoretical integral quantity An.

[0152] Specifically, perform the third time period integral on the sub-actual temperature curve to obtain the actual integral quantity of each sub-actual temperature curve; perform the third time period integral on the sub-theoretical temperature curve to obtain the theoretical integral quantity of each sub-theoretical temperature curve; the third time period is the total time for obtaining the sub-actual temperature curve; calculate the integral difference As between each sub-actual temperature curve of the actual temperature curve and the sub-theoretical temperature curve of its corresponding theoretical integral quantity.

[0153] For example, perform a 10-second integral on the sub-actual temperature curve in each segment of data to obtain the actual integral quantity A1; perform a 10-second integral on the sub-theoretical temperature curve in each segment of data to obtain the theoretical integral quantity An.

[0154] 703. Determine whether the integral difference As exceeds a set threshold, and record the number M of time periods that do not exceed the threshold.

[0155] Specifically, compare each integral difference As with the integral threshold to obtain the total number M of integral differences less than or equal to the integral threshold.

[0156] S704. If the two integral differences As exceed the threshold, do not count; if they do not exceed the threshold, increment the count of M by one, and repeat step 703 until all time periods are calculated.

[0157] S705. Compare the number M of non-exceeding thresholds with the total number S of time periods to obtain the similarity T (M / S).

[0158] Specifically, determine the similarity T (M / S) between the actual temperature curve and the theoretical temperature curve according to the ratio of the total number M to the total number S of integral times of the theoretical temperature curve.
