[0022] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present application.

[0023] REFERENCE Figure 1As shown, the embodiment of the present application provides a linkage control system, comprising: a server 11, a range hood 12, a cooktop 13 and other kitchen equipment with networking function, and further comprising a user terminal 14, wherein the user terminal 14 is a terminal device such as a smart phone or a smart wearable device, the range hood 12, the cooktop 13 and the user terminal 14 are connected to the server 11 through the same wireless network.

[0024] Specifically, the kitchen equipment such as the range hood 12 and the cooktop 13 in the same wireless network with the user terminal 14 is bound to the user terminal 14. For example, the range hood 12 and the cooktop 13 connected to the same WiFi routing address with the user terminal 14 can be bound through the client on the user terminal 14. The bound kitchen equipment such as the range hood 12 and the cooktop 13 is authorized and guided by the user terminal 14 to obtain the linkage authorization of the user to each kitchen equipment. Each kitchen equipment obtaining the linkage authorization reports the state information thereof to the server 11; the user terminal 14 can obtain the state information of the range hood 12 and the cooktop 13 having the binding relationship with the user terminal 14 from the server 11, and the user terminal 14 can display the state information obtained from the server 11, wherein the displayed state information can include the wind power of the range hood 12, the firepower of the cooktop 13 and the like.

[0025] In the embodiment of the present application, the server 11 is configured to obtain the state information reported by the range hood 12 and the cooktop 13, and send a linkage control command to the user terminal 14 when determining that any one of the range hood 12 and the cooktop 13 has a state change according to the state information. The user terminal 14 is configured to receive the linkage control command and execute a linkage action corresponding to the state change on the linkage equipment based on the linkage control command, wherein the linkage equipment of the range hood 12 at least includes the cooktop 13, and the linkage equipment of the cooktop 13 at least includes the range hood 12.

[0026] It can be understood that, in order to improve the accuracy of linkage control, the user terminal 14 is configured to output a user prompt information when receiving the linkage control command sent by the server 11, the user prompt information is used to prompt the user to confirm the linkage control command; the user terminal 14 sends the linkage control command to the corresponding linkage equipment in response to the confirmation operation of the user to the linkage control command, so that the linkage equipment executes the linkage action corresponding to the state change of the range hood 12 or the cooktop 13.

[0027] Unlike the above-mentioned manner, the user terminal 14 can also feed back confirmation information to the server in response to the confirmation operation of the user to the linkage control command; the server 11 sends the linkage control command to the linkage equipment in response to the confirmation information, so that the linkage equipment executes the linkage action corresponding to the state change.

[0028] It can be understood that, in order to make the linkage control more in line with the personalized needs of the user, the user terminal 14 can modify the linkage control command issued by the server 11 according to the user's needs, that is, the user terminal 14 forms a new linkage control command in response to the user's modification operation on the linkage control command executed by the server 11; the user terminal 14 issues a new linkage control command to the linkage device to make the linkage device execute the linkage action corresponding to the state change.

[0029] Specifically, the modification operation can only modify the delay of the linkage device executing the linkage action, or increase or decrease the linkage device executing the linkage action, etc. For example, the linkage control command issued by the server 11 is to execute the linkage action immediately, and the new linkage control command is to execute the linkage action at the time when the hood or the cooktop changes the state and meets the set delay. For another example, the linkage control command issued by the server 11 is to turn off the hood and the air conditioner, and the new linkage control command is only to turn off the air conditioner.

[0030] Based on the same inventive concept, the embodiment of the present application provides a linkage control method applied to the above linkage control system. The following describes the linkage control method from the server as the main part, wherein the hood, the cooktop and the user terminal are connected to the server through the same wireless network, and the hood and the cooktop are bound. Referring to Figure 2 The linkage control method includes the following steps S201-S203:

[0031] S201, the server acquires the state information of the hood and the cooktop.

[0032] Specifically, the hood and the cooktop bound with the user terminal can each actively report the state information to the server when the state changes, or the server can periodically query the state information of the hood and the cooktop.

[0033] S202, the server determines that when any one of the hood and the cooktop changes the state, the linkage control command is sent to the user terminal to make the user terminal control the linkage device to execute the linkage action corresponding to the state change based on the linkage control command, wherein the linkage device of the hood at least includes the cooktop, and the linkage device of the cooktop at least includes the hood.

[0034] Further, the linkage device of the hood and the cooktop can each include an air conditioner in the same indoor environment as the hood and the cooktop, for example, the air conditioner, the hood and the cooktop are all arranged in the kitchen.

[0035] It should be understood that the linkage action executed by the linkage device corresponding to the active device varies with the active device whose state changes. Specifically, if it is determined that the active device whose state changes is the range hood, the linkage device corresponding thereto refers to the cooker or the range hood and the air conditioner; if it is determined that the active device whose state changes is the cooker, the linkage device corresponding thereto refers to the range hood or the range hood and the air conditioner.

[0036] Specifically, if the server determines that the range hood has a state change according to the acquired state information, the linkage control command sent to the user terminal is specifically a first linkage control command for the linkage device of the range hood, so that after the user terminal receives the first linkage control command, the linkage device of the range hood is controlled to execute the linkage action corresponding to the state change of the range hood based on the first linkage control command.

[0037] It should be understood that if the server determines that the cooker has a state change according to the acquired state information, the linkage control command sent to the user terminal is specifically a second linkage control command for the linkage device of the cooker, so that after the user terminal receives the second linkage control command, the linkage device of the cooker is controlled to execute the linkage action corresponding to the state change of the cooker based on the second linkage control command.

[0038] It should be understood that in order to improve the accuracy of linkage control, the user terminal outputs user prompt information when receiving the linkage control command issued by the server, and the user prompt information is used to prompt the user to confirm the linkage control command; the user terminal issues the linkage control command to the linkage device in response to the user's confirmation operation of the linkage control command, otherwise, the user terminal will not issue the linkage control command to the corresponding linkage device, so as to avoid false linkage.

[0039] It should be understood that the first linkage control command issued by the server to the user terminal corresponding to the state change of the range hood varies with the state change of the range hood, and the linkage action executed by the linkage device of the range hood varies with the state change of the range hood; similarly, the second linkage control command issued by the server to the user terminal corresponding to the state change of the cooker varies with the state change of the cooker, and the linkage action executed by the linkage device of the cooker varies with the state change of the cooker. The following examples of linkage control scenarios are given to understand the linkage control method described in the embodiments of the present application:

[0040] Scenario 1: When the server determines that any one of the range hood and the cooker switches from the running state to the off state according to the state information, the linkage shutdown command is sent to the user terminal, so that the corresponding linkage device is controlled to be turned off based on the linkage shutdown command.

[0041] It should be understood that, in order to improve the linkage control accuracy, if it is determined that the range hood switches from the running state to the off state, the server detects whether the linkage device of the range hood is in the running state; if yes, the first linkage off command is sent to the user terminal, so that the user terminal controls the linkage device of the range hood to turn off based on the first linkage off command.

[0042] Taking the linkage device of the range hood as the cooktop for example, when the range hood switches from the running state to the off state in response to the off operation of the user or in response to the delay off program, the server detects whether the cooktop is currently in the burning state; if yes, the first linkage off command is sent to the user terminal, and the user terminal controls the cooktop to turn off based on the first linkage off command.

[0043] For example, a specific case is that when the user manually turns off the range hood, the server detects that the state of the range hood switches from the running state to the off state, and then the server detects whether the cooktop is currently in the burning state; if it is detected that the cooktop is currently in the burning state, the first linkage off command for the cooktop is sent to the user terminal. If the user terminal obtains the confirmation operation of the user for the first linkage off command, the user terminal can send the first linkage off command to the cooktop through the WiFi wireless network to control the cooktop to turn off the fire, so that dry burning can be avoided and the use safety of the cooktop can be improved.

[0044] In the embodiment of the present application, the cooktop is provided with a thermal probe for sensing the burning state of the cooktop, and the server obtains the burning state of the cooktop sensed by the thermal probe.

[0045] It should be understood that, in order to improve the linkage control accuracy, if the cloud service determines that the cooktop switches from the running state to the off state according to the state information, the cloud service detects whether the linkage device of the cooktop is currently in the running state; if yes, the second linkage off command is sent to the user terminal, so that the user terminal controls the linkage device of the cooktop to turn off based on the second linkage off command.

[0046] Taking the linkage device of the cooktop as the range hood for example, when the cooktop switches from the running state to the off state in response to the off operation of the user, in response to the timing cooking program or when the cooktop accidentally turns off the fire, the server detects whether the range hood is currently in the running state; if yes, the second linkage off command is sent to the user terminal, and the user terminal controls the linkage device of the cooktop to turn off based on the second linkage off command, so that the electric energy can be saved.

[0047] For example, in order to avoid the safety hazard of gas leakage, a specific case is that the heat-sensitive probe arranged on the stove senses the stove combustion state, the server acquires the stove combustion state sensed by the heat-sensitive probe, and according to the stove combustion state, when the stove is accidentally extinguished, the server controls the stove to automatically cut off the gas, and detects whether the range hood is currently in an operating state, if so, the server issues a second linkage shutdown command for the range hood to the user terminal, and the user terminal controls the range hood to shut down based on the second linkage shutdown command.

[0048] Scenario 2: When the server determines that the stove switches from the off state to the running state according to the state information, a linkage start command is sent to the user terminal; wherein the linkage start command is used to control the user terminal to start the linkage device of the stove, thereby reducing the user operation and facilitating the user.

[0049] It can be understood that in addition to the above-mentioned linkage of the opening and closing of the linkage device of the range hood and the stove, linkage adjustment between wind power and fire power of the range hood and the stove in the running state can also be performed:

[0050] For example, scenario 3: when the server determines that the fire power of the stove changes according to the state information, a linkage wind power adjustment command is sent to the user terminal, so that the user terminal adjusts the wind power of the range hood to match the changed fire power of the stove based on the linkage wind power adjustment command.

[0051] Specifically, when the server determines that the fire power of the stove changes according to the state information, the current wind power of the range hood and the changed fire power of the stove are acquired; whether the current wind power matches the changed fire power is compared; if not, the server issues a linkage wind power adjustment command to the user terminal, so that the user terminal adjusts the wind power of the range hood to match the changed fire power of the stove based on the linkage wind power adjustment command, thereby saving the energy consumption of the range hood when the fire is small and effectively and quickly exhausting the smoke when the fire is large.

[0052] It should be understood that the change of the fire power of the stove can be triggered by the user's adjustment of the fire power or based on a preset cooking program. For example, a certain preset cooking program is used to cook a certain dish by multiple fire powers, and during the cooking process, the stove will automatically adjust the fire power multiple times based on the preset cooking program. Therefore, after the stove adjusts the fire power each time, the server determines the current fire power change of the stove according to the state information, and after the stove adjusts the fire power each time, the server issues a linkage wind power adjustment command to the user terminal for the current fire power change, so that the user terminal adjusts the wind power of the range hood to match the current changed fire power of the stove based on the linkage wind power adjustment command.

[0053] It should be noted that the greater the firepower of the stove, the greater the linkage adjustment of the wind power of the range hood, and the firepower of the stove and the wind power of the range hood can be in a gear corresponding relationship, a linear relationship or a nonlinear relationship, which is not limited here.

[0054] It should be understood that the linkage control between the range hood and the stove also includes: obtaining environmental light intensity change data generated by the cooking process of the range hood and the stove in the target historical period, wherein the obtained environmental light intensity change data is based on the environmental smoke concentration change in the cooking process of the target historical period; machine learning is performed using the environmental light intensity change data to obtain the cooking habit analysis result of the user in the target historical period; the prompt information is determined according to the cooking habit analysis result, and the prompt information is sent to the user terminal to make the user terminal display the prompt information.

[0055] Since the cooking process produces oil fume, resulting in changes in environmental smoke concentration, a smoke sensor can be configured on the range hood. The smoke sensor is based on Mie scattering principle to obtain the environmental light intensity change data generated by the change in environmental smoke concentration in the cooking process of the target historical period.

[0056] The environmental light intensity change can be understood with reference to the following formula:

[0057]

[0058] Wherein, α is a dimensionless particle size parameter, m1 is the refractive index of the dispersed medium around the particle, d is the particle diameter, f is the frequency of light, and c is the speed of light. With the change of environmental smoke concentration, α changes, and the increase of α makes the scattered light intensity concentrated in the forward direction, that is, the light intensity increases. Therefore, due to the change of environmental smoke concentration in the cooking process, the smoke sensor will collect the environmental light intensity change data generated by the change of environmental smoke concentration.

[0059] Specifically, in order to improve the accuracy of cooking habit analysis, the target historical period can be the last 14 days or longer.

[0060] It should be understood that machine learning using environmental light intensity change data can obtain cooking habit analysis results of the user, and based on the cooking habit analysis results, at least one corresponding prompt information can be determined.

[0061] For example, the environmental light intensity change data includes a plurality of light intensity change curves, and each cooking in the target historical period corresponds to a light intensity change curve. The light intensity change curve generated by each cooking in the target historical period is used for light intensity analysis, and the cooking action sequence and / or oil fume concentration change characteristic of the user in the cooking are obtained. Based on the cooking action sequence and / or oil fume concentration change characteristic of each cooking in the target historical period, machine learning is performed to determine the cooking habit analysis result of the user in the target historical period.

[0062] Taking the process of one-time stir-frying cooking as an example, the relationship between the light intensity change process in the cooking process and the user's cooking action is shown in the following Table 1:

[0063] Table 1.

[0064]

[0065] In the embodiment of the present application, the obtained cooking habit analysis result can be a diet habit level of the target historical period, and the diet habit level is one of various diet habit levels such as heavy oil diet, medium oil diet, light oil diet, etc. According to the difference of the diet habit level, the information content of the prompt information is different.

[0066] Specifically, according to the cooking habit analysis result, one or more of the following prompt information is determined:

[0067] 1. The recommended air volume level matched with the diet habit level is determined for the range hood;

[0068] 2. The remaining capacity of the oil box of the range hood;

[0069] 3. The fan cleanliness of the range hood;

[0070] 4. The cooking recipe content for the cooktop determined according to the diet habit level.

[0071] Among them, for the prompt information 1, for example, a first mapping relationship between each diet habit level and air volume level can be established in advance, and the air volume level matched with the diet habit level of the target historical period is determined based on the first mapping relationship.

[0072] For example: three air volume levels (high, medium, and low) and three diet habit levels (heavy oil diet, medium oil diet, and light oil diet) are one-to-one mapped, if the user is obtained as a heavy oil diet habit, the determined recommended air volume level is a high air volume level; if the user is obtained as a medium oil diet habit, the determined recommended air volume level is a medium air volume level; if the user is obtained as a light oil diet habit, the determined recommended air volume level is a low air volume level.

[0073] It should be understood that the recommended air volume level is not limited to the above-mentioned manner, for example: the diet habit classification result can be a diet oil quantification value, then a conversion formula can be configured in advance to convert the diet oil quantification value to obtain a recommended air volume value; based on the air volume level where the air volume value is located, the recommended air volume level is determined to solve the problem of poor smoke exhaust or excessive noise caused by inappropriate user setting of the level.

[0074] Wherein, for the prompt information 2, a second mapping relationship between each eating habit level and oil production in the cooking process can be established in advance; based on the second mapping relationship, the actual oil production of the cooking process in the target historical period is determined; the actual oil production generated by the cooking in each different historical period is accumulated to obtain the total historical oil production until the current time; based on the total capacity of the oil box of the range hood and the total historical oil production, the remaining capacity of the oil box of the range hood is determined.

[0075] Wherein, for the prompt information 3, a third mapping relationship between each eating habit level and the oil smoke attachment amount of the fan can be established in advance; based on the third mapping relationship, the actual oil smoke attachment amount of the fan in the target historical period is determined; the actual oil smoke attachment amount of the fan in each different historical period is accumulated to obtain the total oil smoke attachment amount of the fan until the current time; based on the total oil smoke attachment amount, the cleanliness of the fan of the range hood is determined.

[0076] Wherein, for the prompt information 4, when the eating habit level in the target historical period is greater than or equal to the preset eating habit level, one or more recipes belonging to the target eating habit level can be obtained, wherein the target eating habit level is lower than the preset eating habit level or lower than the eating habit level in the target historical period. For example, the preset eating habit level is heavy oil diet, if the eating habit level in the target historical period is heavy oil diet, the medium oil diet level recipe and / or the light oil diet level recipe can be obtained.

[0078] It can be understood that the linkage control unit 302 can comprise: a shutdown linkage control subunit, configured to, when any one of the range hood and the stove switches from a running state to a shutdown state according to the state information, send a linkage shutdown command to the user terminal; wherein the linkage shutdown command is used for the user terminal to control the linkage device to shut down.
