Description

Technical Field

[0001] The present invention relates to the technical field of kitchen stoves and electrical appliances, and in particular to a control method, device, equipment and medium for the linkage between a stove and a range hood. Background Art

[0002] As people's living standards gradually improve, the combination of gas stoves and range hoods has become an indispensable kitchen appliance in every household.

[0003] In the past, gas stoves and range hoods operated separately. Only when the user turned on the range hood could it absorb the oil smoke in a fixed absorption area. Sometimes the range hood's gears couldn't keep up with the user's cooking method, resulting in poor oil smoke absorption. Furthermore, when users manually turned on the range hood, they often remembered to turn it on only after the oil smoke was generated, resulting in a delay in the range hood's activation and ineffective oil smoke removal. Therefore, it is very necessary to provide a method for integrated control of stoves and range hoods. Summary of the Invention

[0004] In order to improve the oil fume treatment efficiency of the range hood, the present application provides a control method, device, equipment and medium for the linkage between a stove and a range hood.

[0005] The above-mentioned invention objective of this application is achieved through the following technical solutions:

[0006] A control method for a stove and a range hood linkage, the control method for a stove and a range hood linkage comprising:

[0007] When the cooker start message is obtained, a range hood start instruction is generated to start the range hood to work;

[0009] Inputting the stove firepower information and the cooking method into a preset oil smoke amount prediction model to obtain a predicted oil smoke generation amount;

[0010] determining a corresponding range hood gear according to the predicted amount of oil smoke generated, and generating a gear switching instruction according to the range hood gear;

[0011] When the stove shutdown message is obtained, a range hood delay operation instruction is generated, and when the range hood delay operation ends, a range hood shutdown instruction is generated.

[0012] By adopting the above technical solution, since the oil smoke in the fixed absorption area can only be absorbed when the user turns on the range hood for use, sometimes the gear of the range hood cannot keep up with the user's cooking method, resulting in poor oil smoke absorption effect, and when the user manually turns on the range hood, most of the time it is after the oil smoke is generated that the range hood is turned on late, which cannot achieve a good oil smoke removal effect. Therefore, when the stove start-up message is obtained, the present application generates a range hood start-up instruction to start the range hood to work, which helps to improve the synchronization of the range hood start-up, thereby improving the oil fume treatment effect. By obtaining the continuous image group of the stove and the corresponding cooking sound data, the stove firepower information and cooking method are determined according to the continuous image group and the cooking sound data, which helps to real-time Monitor the firepower of the stove and determine the user's cooking method to improve the accuracy of the results. By inputting the stove firepower information and cooking method into the preset oil fume prediction model, the predicted oil fume generation amount is obtained, the accuracy of the predicted oil fume generation amount is improved, and the oil fume generation lag caused by the range hood gear switching is reduced. It can effectively remove oil fume. By determining the corresponding range hood gear according to the predicted oil fume generation amount, and generating a gear switching instruction according to the range hood gear, it helps the range hood to achieve a better oil fume treatment effect and improve the oil fume treatment efficiency. When the stove shutdown message is obtained, a range hood delay work instruction is generated, and when the range hood delay work ends, a range hood shutdown instruction is generated, which helps to improve the use efficiency of the range hood, improve the oil fume treatment efficiency, and keep the kitchen environment clean.

[0018] By adopting the above technical solution, feature extraction technology is used to extract features from continuous image groups to further reduce the data dimension of the continuous image groups and reduce the complexity of data processing, so as to quickly determine the angle of the fire knob in the continuous image group, thereby judging the fire power of the stove, and based on the sound recognition technology, feature extraction is performed on the cooking sound data to determine the sound generated by the user during the cooking process, and then, based on the sound characteristics and the stove fire power information, the cooking method used by the user is judged and generated, thereby improving the accuracy of the generated results.

[0019] In a preferred example, the present application may be further configured as follows: before inputting the stove power information and cooking method into a preset oil smoke amount prediction model and obtaining the predicted amount of oil smoke generated, constructing an oil smoke amount prediction model, specifically including:

[0021] Associating and marking the historical stove firepower information with the historical cooking methods to construct a data group to be trained;

[0022] The initial model is trained according to the data group to be trained to obtain an oil smoke volume prediction model.

[0023] By adopting the above technical solution, by obtaining historical stove firepower information, historical cooking methods and corresponding historical oil fume volume data, and associating and marking the historical stove firepower information with the historical cooking methods, a data group to be trained is constructed, so that the data group to be trained is used to train the initial model, and the trained oil fume volume prediction model can accept the stove firepower information and cooking method as input, judge the oil fume production amount generated by the cooking behavior and the stove firepower as output, realize the prediction of the oil fume production amount, and improve the credibility of the prediction result.

[0024] In a preferred example, the present application may be further configured as follows: determining the corresponding range hood gear according to the predicted amount of oil smoke generated, and generating a gear switching instruction according to the range hood gear, specifically including:

[0025] Matching the predicted range hood generation amount with a preset range hood gear mapping table to obtain the range hood gear corresponding to the predicted range hood generation amount;

[0026] The range hood gear position is compared with a real-time range hood gear position, and when the range hood gear position does not meet the real-time range hood gear position, a gear switching instruction is generated.

[0027] By adopting the above technical solution, by matching the predicted range hood generation amount with the preset range fume gear mapping table, the range hood gear corresponding to the predicted range hood generation amount is obtained, which helps to improve the accuracy of the obtained range hood gear, so as to accurately adjust the range hood gear, and compare the range hood gear with the real-time range hood gear. When the range hood gear does not meet the real-time range hood gear, a gear switching instruction is generated to switch the range hood gear to the corresponding gear to achieve better fume removal effect.

[0028] In a preferred example, the present application can be further configured as follows: when the stove shutdown message is obtained, a range hood delay operation instruction is generated, and when the range hood delay operation ends, a range hood shutdown instruction is generated, specifically including:

[0029] According to the range hood delay operation instruction, a preset delay off time of the range hood is obtained and a gear adjustment instruction is generated, and the gear of the range hood is adjusted to a preset minimum gear according to the gear adjustment instruction;

[0030] The range hood operation time is set as the delayed closing time, and when the range hood runs to the delayed closing time, the range hood shutdown instruction is generated.

At the same time, the range hood operation time is set to the obtained delayed shutdown time, so that when the range hood runs to the delayed shutdown time, a range hood shutdown instruction is generated, and the range hood is turned off according to the range hood shutdown instruction, which helps to achieve the effect of absorbing kitchen oil smoke and removing kitchen odors, so that the kitchen maintains fresh air.

[0032] In a preferred example, the present application may be further configured as follows: the control method for the linkage between the stove and the range hood further includes:

[0033] Acquiring range hood gear usage data, analyzing the range hood gear usage data, and obtaining commonly used gear information;

[0034] A gear initialization instruction is generated according to the conventional gear information, and an initial startup gear of the range hood is set according to the gear initialization instruction.

[0035] By adopting the above technical solution, by obtaining the range hood gear usage data and analyzing the range hood gear usage data, the usual gear information is obtained, which helps to understand the user's usage habits and infer the usage of the range hood gear. Based on the usual gear information, the gear initial instruction is generated, and the initial starting gear of the range hood is set according to the gear initial instruction, so as to effectively reduce the number of range hood gear switching times and improve the use efficiency of the range hood.

[0036] The second object of the present invention is achieved through the following technical solutions:

[0040] A model prediction module is used to input the stove firepower information and cooking method into a preset oil smoke amount prediction model to obtain a predicted amount of oil smoke;

[0041] a gear adjustment module, configured to determine a corresponding range hood gear according to the predicted amount of oil smoke generated, and generate a gear switching instruction according to the range hood gear;

[0042] The residual smoke absorption module is used to generate a range hood delay operation instruction when a message that the stove fire is extinguished is obtained, and to generate a range hood shutdown instruction when the range hood delay operation ends.

[0043] By adopting the above technical solution, since the oil smoke in the fixed absorption area can only be absorbed when the user turns on the range hood for use, sometimes the gear of the range hood cannot keep up with the user's cooking method, resulting in poor oil smoke absorption effect, and when the user manually turns on the range hood, most of the time it is after the oil smoke is generated that the range hood is turned on late, which cannot achieve a good oil smoke removal effect. Therefore, when the stove start-up message is obtained, the present application generates a range hood start-up instruction to start the range hood to work, which helps to improve the synchronization of the range hood start-up, thereby improving the oil fume treatment effect. By obtaining the continuous image group of the stove and the corresponding cooking sound data, the stove firepower information and cooking method are determined according to the continuous image group and the cooking sound data, which helps to real-time Monitor the firepower of the stove and determine the user's cooking method to improve the accuracy of the results. By inputting the stove firepower information and cooking method into the preset oil fume prediction model, the predicted oil fume generation amount is obtained, the accuracy of the predicted oil fume generation amount is improved, and the oil fume generation lag caused by the range hood gear switching is reduced. It can effectively remove oil fume. By determining the corresponding range hood gear according to the predicted oil fume generation amount, and generating a gear switching instruction according to the range hood gear, it helps the range hood to achieve a better oil fume treatment effect and improve the oil fume treatment efficiency. When the stove shutdown message is obtained, a range hood delay work instruction is generated, and when the range hood delay work ends, a range hood shutdown instruction is generated, which helps to improve the use efficiency of the range hood, improve the oil fume treatment efficiency, and keep the kitchen environment clean.

[0044] The third objective of this application is achieved through the following technical solutions:

[0045] A computer device includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the steps of the control method for the linkage between a stove and a range hood are implemented.

[0046] The fourth objective of this application is achieved through the following technical solutions:

[0047] A computer-readable storage medium stores a computer program, which, when executed by a processor, implements the steps of the control method for the linkage between a stove and a range hood.

[0048] In summary, this application includes at least one of the following beneficial technical effects:

[0049] 1. By obtaining historical stove power information, historical cooking methods, and corresponding historical oil fume volume data, and associating and labeling the historical stove power information with the historical cooking methods, a training data set is constructed, so that the training data set can be used to train the initial model. The trained oil fume volume prediction model can then accept stove power information and cooking methods as input, determine the oil fume volume generated by the cooking behavior and stove power, and output it as output, thereby achieving oil fume volume prediction and improving the credibility of the prediction results.

[0050] 2. By matching the predicted range hood generation amount with a preset range fume level mapping table, the range hood level corresponding to the predicted range hood generation amount is obtained, which helps to improve the accuracy of the obtained range hood level so as to accurately adjust the range hood level. The range hood level is then compared with the real-time range hood level. When the range hood level does not meet the real-time range hood level, a level switching instruction is generated to switch the range hood level to the corresponding level to achieve a better range fume removal effect.

[0051] 3. When receiving a stove shutdown message, the preset delayed shutdown time of the range hood is obtained according to the range hood delayed working instruction, and a gear adjustment instruction is generated to adjust the range hood gear to the minimum gear of the range hood, which helps to absorb the remaining oil smoke in the kitchen and improve the utilization efficiency of the range hood. At the same time, the range hood operation time is set to the obtained delayed shutdown time. When the range hood runs to the delayed shutdown time, a range hood shutdown instruction is generated.

[0061] The present application is further described in detail below with reference to the accompanying drawings.

[0062] In one embodiment, if Figure 1 As shown, the present application discloses a control method for the linkage between a stove and a range hood, which specifically includes the following steps:

[0063] S10: When the stove start message is obtained, a range hood start instruction is generated to start the range hood to work.

[0064] In this embodiment, the stove start message refers to a message for a user to ignite the stove when cooking food. The range hood start instruction refers to an instruction for starting the range hood to process oil fumes.

[0065] Specifically, when the user needs to use a stove to cook food, when the user performs an ignition operation to start the stove to process food, the stove sends a stove start-up message, which generates a range hood start-up instruction for starting the range hood to process oil fumes, so that the range hood can be automatically turned on synchronously with the stove being turned on.

[0066] S20: Acquire a continuous image group of the stove and corresponding cooking sound data, and determine stove firepower information and cooking mode based on the continuous image group and cooking sound data.

[0067] In this embodiment, the continuous image group refers to images of the stove captured by the camera equipped with the range hood. The cooking sound data refers to the sounds produced by the user while cooking. The heat information refers to the heat level of the stove. The cooking method refers to the method used by the user to cook food.

[0068] Specifically, a continuous image group of the stove is captured by a camera equipped with a range hood, and the image group includes multiple frames of continuous images in time. The cooking sound data corresponding to the continuous image group is recorded by a sound sensor to judge the user's cooking behavior. Therefore, based on the continuous image group and the cooking sound data, the stove fire power and cooking method used by the user in the food cooking process are determined. The stove fire power has three fire power options: large, medium and small. The cooking behavior can be frying, deep-frying or stir-frying.

[0069] S30: Inputting the stove firepower information and cooking method into a preset oil smoke amount prediction model to obtain the predicted oil smoke generation amount.

[0070] In this embodiment, the predicted amount of oil smoke generated refers to the predicted amount of oil smoke generated based on the user's cooking behavior and the fire power of the stove used.

[0071] Specifically, by inputting the stove firepower information and cooking method into a preset oil fume quantity prediction model, the oil fume quantity prediction model judges the degree of impact of the cooking behavior and the stove firepower on the generation of oil fume based on the input stove firepower information and cooking method, predicts the generation of oil fume, and thus outputs the predicted amount of oil fume generated.

[0072] S40: Determine the corresponding range hood gear according to the predicted amount of oil smoke generated, and generate a gear switching instruction according to the range hood gear.

[0073] In this embodiment, the gear switching instruction refers to an instruction for controlling the range hood to switch gears.

[0074] Specifically, based on the preset predicted amount of oil fume production, the corresponding range hood gear that can effectively remove oil fume under the predicted amount of oil fume production is determined, and a gear switching instruction is generated based on the range hood gear to control the range hood to switch gears, so as to switch the gear of the range hood to this gear, thereby achieving a better oil fume treatment effect.

[0075] S50: When the stove shutdown message is obtained, a range hood delay operation instruction is generated, and when the range hood delay operation ends, a range hood shutdown instruction is generated.

[0076] In this embodiment, the stove-off message refers to a message for turning off the stove when the user finishes cooking. The range hood delay operation instruction refers to an instruction for controlling the range hood to delay operation. The range hood shutdown instruction refers to an instruction for controlling the range hood to shut down.

[0077] Specifically, when the stove-off message is obtained, that is, the stove fire is extinguished, indicating that the user has finished cooking the food and turned off the stove. At this time, no new oil smoke will be generated. Therefore, a range hood delay work instruction is generated according to the stove-off message, and the range hood is controlled to absorb the remaining oil smoke in the kitchen to keep the kitchen air fresh and unobstructed. When the range hood delay reaches the preset shutdown time, a range hood shutdown instruction is generated to turn off the range hood.

[0078] In this embodiment, since the range hood can only absorb the oil smoke in the fixed absorption area when the user turns on the range hood for use, sometimes the gear of the range hood cannot keep up with the user's cooking method, resulting in poor oil smoke absorption effect, and when the user manually turns on the range hood, most of the time it is only after the oil smoke is generated that the range hood is turned on late, resulting in a delay in the opening of the range hood, and unable to achieve a good oil smoke removal effect. Therefore, when the stove start-up message is obtained, the present application generates a range hood start-up instruction to start the range hood to work, which helps to improve the synchronization of the range hood start-up, thereby improving the oil smoke treatment effect. By obtaining a continuous image group of the stove and the corresponding cooking sound data, the stove firepower information and cooking method are determined according to the continuous image group and the cooking sound data, which helps to monitor the stove in real time. The firepower of the stove and the cooking method of the user are determined to improve the accuracy of the results. By inputting the stove firepower information and cooking method into the preset oil fume prediction model, the predicted oil fume generation amount is obtained, the accuracy of the predicted oil fume generation amount is improved, and the oil fume generation lag caused by the range hood gear switching is reduced. It can efficiently remove oil fume. By determining the corresponding range hood gear according to the predicted oil fume generation amount, and generating a gear switching instruction according to the range hood gear, it helps the range hood to achieve a better oil fume treatment effect and improve the oil fume treatment efficiency. When the stove shutdown message is obtained, a range hood delay work instruction is generated, and when the range hood delay work ends, a range hood shutdown instruction is generated, which helps to improve the use efficiency of the range hood, improve the oil fume treatment efficiency, and keep the kitchen environment clean.

[0079] In one embodiment, if Figure 2 As shown, in step S20, a continuous image group of the stove and corresponding cooking sound data are obtained, and the stove firepower information and cooking method are determined based on the continuous image group and cooking sound data, which specifically includes:

[0080] S21: Using feature extraction technology, extract features from the continuous image group to obtain a fire knob feature group.

[0081] Specifically, by adopting feature extraction technology, wherein feature extraction technology refers to a technology for extracting features using a feature extraction network, feature extraction is performed on a continuous image group to obtain a power knob feature group.

[0082] S22: Compare the firepower knob feature group with the preset firepower feature to obtain the stove firepower information.

[0083] Specifically, by comparing the fire knob feature group with the preset fire power feature, the rotation angle of the fire knob of the fire knob feature group is determined, so that when the angle of the fire knob in the continuous image group can match the fire knob angle in the preset fire power feature, the preset fire power feature is the knob angle corresponding to the fire power size. When the rotation angle of the fire knob is 0°, it indicates that the fire power of the stove is extinguished. When the rotation angle of the fire knob is 90°, it indicates that the fire power of the stove is in a low fire state. According to the matching of the fire knob feature group and the preset fire power feature, the stove fire power information is obtained.

[0084] S23: Based on the sound recognition technology, feature extraction is performed on the cooking sound data to obtain sound features.

[0085] Specifically, during the food cooking process, there will be sounds such as the sound of oil splashing when frying food, the friction sound produced by the spatula rubbing against the bottom of the pot when stir-frying, and the sound of ingredients turning in the pot. Therefore, based on sound recognition technology, the cooking sound data collected during the cooking process is feature extracted to obtain sound features that can directly reflect the cooking process after de-cluttering.

[0086] S24: Generate a cooking method based on the sound characteristics and the stove fire power information.

[0087] Specifically, based on the obtained sound characteristics and the stove firepower information, such as whether the user is stewing food when using a low fire, the cooking method selected by the user can be accurately judged, making the cooking method more accurate.

[0088] In one embodiment, if Figure 3 As shown, before step S30, that is, inputting the stove firepower information and cooking mode into the preset oil smoke amount prediction model, before obtaining the predicted amount of oil smoke generated, constructing the oil smoke amount prediction model, specifically including:

[0089] S301: Obtain historical stove firepower information, historical cooking methods, and corresponding historical oil smoke volume data.

[0090] In this embodiment, historical stove power information refers to the power level of the stove in operation over the past period of time. Historical cooking methods refer to the cooking methods used by the user. Historical oil smoke volume refers to the amount of oil smoke generated when the user uses the stove to cook food.

[0091] Specifically, the historical stove firepower information, historical cooking methods and corresponding historical oil smoke volume data are obtained from a database storing past data to predict the oil smoke generation situation.

[0092] S302: Associating and labeling historical stove firepower information with historical cooking methods to construct a data set to be trained.

[0093] Specifically, after obtaining the historical stove firepower information and historical cooking methods corresponding to the historical oil smoke volume data, the historical stove firepower information is associated with the historical cooking methods and stored in a preset database to construct a data group to be trained.

[0094] S303: Training the initial model according to the data set to be trained to obtain an oil smoke volume prediction model.

[0095] Specifically, a preset initial model is selected and trained based on the data group to be trained, so that the trained oil fume amount prediction model can accept the stove fire power information and cooking method as input, and judge the amount of oil fume generated by the cooking behavior and the stove fire power as output.

[0096] In one embodiment, if Figure 4 As shown, in step S40, the corresponding range hood gear is determined according to the predicted amount of oil smoke generated, and a gear switching instruction is generated according to the range hood gear, which specifically includes:

[0097] S41: Matching the predicted range hood generation amount with a preset range hood level mapping table to obtain the range hood level corresponding to the predicted range hood generation amount.

[0098] Specifically, a range hood gear mapping table is pre-stored in the system. The range hood gear mapping table records the mapping relationship between the amount of oil smoke and the range hood gear. The range hood predicted production amount is matched with the preset range hood gear mapping table to obtain the range hood gear corresponding to the predicted production amount. For example, if the predicted oil smoke production amount is 1mg / m 3 , which belongs to the second level of the oil smoke volume in the preset oil smoke gear mapping table, wherein the range of the second level is (0.8, 1.2], and the range hood gear corresponding to the second level is the second gear, which can effectively absorb the oil smoke generated by the user's cooking.

[0099] S42: Compare the range hood gear position with the real-time range hood gear position, and generate a gear switching instruction when the range hood gear position does not meet the real-time range hood gear position.

[0100] Specifically, the range hood gear is compared with the real-time range hood gear to determine whether the current range hood needs to be switched. When the range hood gear does not meet the real-time range hood gear, it indicates that the current range hood gear may be too high or too low, and the range hood gear needs to be adjusted. Therefore, a gear switching instruction is generated to control the range hood to switch the gear, so that the range hood gear is switched to this gear, thereby achieving a better oil fume treatment effect.

[0101] In one embodiment, if Figure 5 As shown, in step S50, that is, when the stove shutdown message is obtained, a range hood delay operation instruction is generated, and when the range hood delay operation ends, a range hood shutdown instruction is generated, which specifically includes:

[0102] S51: According to the range hood delay operation instruction, a preset delay off time of the range hood is obtained and a gear adjustment instruction is generated, and the gear of the range hood is adjusted to a preset minimum gear according to the gear adjustment instruction.

[0103] In this embodiment, the gear adjustment instruction refers to an instruction for controlling the range hood to adjust to the minimum gear.

[0104] Specifically, when the stove shutdown message is obtained, that is, when the user turns the fire knob to turn off the flame after finishing cooking the food, a range hood delay work instruction is generated at the same time. Therefore, according to the range hood delay work instruction, the preset delayed shutdown time of the range hood is obtained. For example, the delayed shutdown time may be different due to different brands, and may be 30 seconds or 1 minute, etc., and a gear adjustment instruction is generated to control the range hood to adjust to the minimum gear. According to the gear adjustment instruction, the range hood is adjusted to the minimum gear to absorb the remaining oil smoke in the kitchen.

[0105] S52: The range hood operation time is set to the delayed shutdown time, and when the range hood runs to the delayed shutdown time, a range hood shutdown instruction is generated.

[0106] Specifically, the range hood operation time is set to the delayed shutdown time so that the range hood can absorb the remaining oil smoke in the kitchen. Then, when the range hood runs to the delayed shutdown time, a range hood shutdown instruction is generated, and the range hood is shut down according to the range hood shutdown instruction.

[0107] In one embodiment, if Figure 6 As shown, the control method for the linkage between the stove and the range hood also includes:

[0108] S60: Acquire range hood gear usage data, analyze the range hood gear usage data, and obtain commonly used gear information.

[0109] In this embodiment, the range hood gear usage data refers to data on the usage of the range hood gears. The commonly used gear information refers to information on the gears that the user frequently uses when using the range hood.

[0110] Specifically, by obtaining range hood gear usage data of the range hood gear usage, and analyzing the range hood gear usage data, analyzing the changes in the range hood gear when the user uses it, the range hood gear that the user frequently uses is screened out, thereby obtaining the commonly used gear information.

[0111] S61: Generate an initial gear instruction according to the usual gear information, and set the initial starting gear of the range hood according to the initial gear instruction.

[0112] In this embodiment, the gear initialization instruction refers to an instruction for setting the initial gear after the oil smoke is started.

[0113] Specifically, based on the commonly used gear information obtained through analysis, an initial gear instruction is generated, and the initial starting gear of the range hood is set according to the initial gear instruction, so as to effectively reduce the number of gear switching times of the range hood and improve the use efficiency of the range hood.

[0114] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0115] In one embodiment, a control device for the linkage between a stove and a range hood is provided, and the control device for the linkage between a stove and a range hood corresponds to the control method for the linkage between a stove and a range hood in the above embodiment. Figure 7 As shown, the control device for the linkage between the stove and the range hood includes a range hood activation module, a state acquisition module, a model prediction module, a gear adjustment module, and a residual smoke absorption module.
