When the actual system or server product executes, it can be executed in the order shown in the embodiment or the drawing or executed in parallel (for example, in an environment of parallel processors or multi-threaded processing). Specifically, as Figure 1 shown, the method may include:

[0047] S101. Obtain a sensing data set of the cookware stand.

[0048] For the schematic diagrams of the cookware stand 2 and the cookware 3, reference can be made to Figure 2 and Figure 3 . During use, the cookware 3 is usually placed on the cookware stand 2. The cookware stand 2 can stably support the cookware 3 during cooking, reducing the situation where the cookware 3 tilts and overturns. The cookware stand 2 includes at least one foot piece 21 in contact with the cookware 3, and the cookware stand 2 supports the cookware 3 through the foot piece 21. A force sensor 23 is provided on the surface of the foot piece 21 in contact with the cookware 3. The force sensor 23 is used to collect the contact force between each foot piece 21 and the cookware 3 to obtain a sensing data set, and the sensing data set includes the contact force between each foot piece 21 and the cookware 3. The contact force generally refers to the force generated when two objects come into contact with each other, including one or more of, but not limited to, the normal force (i.e., pressure) and the tangential force (i.e., friction force).

[0049] S102. Determine the state of the cookware according to the contact force of any one foot piece.

[0050] Among them, the states of the cookware specifically include, but are not limited to, any one or more of the following: initial state, pre-sliding state, sliding state, lifting state, flipping state, etc.

[0051] Generally, during the cooking process of the user, in order to cook the dishes evenly or make the food flavorful, various different operations will be performed on the cookware 3, such as turning the pot, lifting the pot, etc. Similarly, in some cases of improper operation, the cookware 3 may slide due to uneven force. The above-mentioned states of the cookware will be described in detail below:

[0052] Regarding the initial state, the cookware support 2 can stably hold the cookware 3, making it not easy for the cookware 3 to tilt and slip. The cookware 3 in the initial state is stationary. At the same time, each foot piece 21 on the cookware support 2 is at a first preset height, and the setting of the first preset height is selected according to the actual situation and will not be particularly limited herein.

[0053] Regarding the pre-sliding state and the sliding state, when the cookware 3 slides from a stationary state, it usually goes through a static friction stage, a critical stage, and a sliding stage. In the static friction stage, the tangential force between the cookware 3 and any one foot piece 21 continuously increases, but there is no displacement between the cookware 3 and the cookware support 2; in the critical stage, the ratio of the tangential force to the normal force between the cookware 3 and any one foot piece 21 will reach a first preset threshold. Although the cookware 3 is in the critical stage between sliding and stationary at this time, there is still no displacement between the cookware 3 and the cookware 3. The first preset threshold is usually determined by the coefficient of static friction and will be described in detail later; in the sliding stage, the normal force between the cookware 3 and any one foot piece 21 suddenly drops, and at this time, there is a displacement between the cookware 3 and the cookware support 2, and the cookware 3 is in the sliding stage. Based on this, in this embodiment, the critical stage between sliding and stationary of the cookware 3 is defined as the pre-sliding state, and the sliding stage of the cookware 3 is defined as the sliding state. In addition, the sliding state is usually not caused by the user's intention to use the cookware 3, but by unexpected events caused by some improper operations, such as the user's hand slipping, too much force on one side of the cookware 3, etc. When the cookware 3 is in the sliding state, it is easy to cause the dishes in the cookware 3 to be spilled, etc., affecting the user experience.

[0054] Regarding the lifting state, the contact force between the cookware 3 and the cookware support 2 disappears, and the cookware 3 is lifted by the user and leaves the cookware support 2.

[0055] Regarding the flipping state, the tangential force between the cookware 3 and the cookware support 2 fluctuates periodically, and the acceleration of the cookware 3 changes alternately in multiple directions. This is because during the cooking process, the user usually needs to flip the cookware 3 to make the food in the cookware 3 heated evenly and the seasonings distributed evenly, etc.

[0056] Under normal circumstances, both the pot-lifting state and the pot-tossing state are generated under the user's intention of use and are within the user's controllable range, and there will be no situation of spilling dishes like in the pot-sliding state.

[0057] S103. Adjust the pot support based on the state of the cooking pot.

[0058] According to the various cooking pot states mentioned above, for each cooking pot state, there is a corresponding adjustment method to adjust the pot support 2. The purpose of adjusting the pot support 2 is to enable the cooking pot 3 to be stably placed on the pot support 2, reduce the situation of the dishes in the cooking pot being overturned, etc., and improve the user experience.

[0059] For example, when the cooking pot state is in the pre-sliding state, the height of the foot piece 21 of the pot support 2 can be adjusted to prevent the cooking pot 3 from slipping; or when the cooking pot state is the pot-lifting state, the height of the pot support 2 can also be adjusted so that the pot support 2 can better support the cooking pot 3 after being lifted and put down. Generally speaking, for different cooking pot states, the user can configure different adjustment methods according to the specific usage scenario.

[0060] In this embodiment, the state of the cooking pot is determined by the contact force between the cooking pot and the foot piece on the pot support. Along with different cooking pot states during the use of the cooking pot, the contact force on the foot piece will also change accordingly. Based on this, different states of the cooking pot can be quickly identified, and the pot support can be adjusted based on different cooking pot states, which can effectively prevent accidental situations such as pot sliding caused by improper operation during the use of the cooking pot, and improve the safety and effectiveness of kitchen cooking. At the same time, compared with the method of using anti-slip structures, it can prevent problems such as anti-slip failure caused by wear of the anti-slip structure and improve the anti-slip effect.

[0061] The determination methods and adjustment methods for various different cooking pot states are described in detail below, but are not limited thereto, and the user can set according to the actual situation:

[0062] The contact force includes pressure and friction , and at the same time, pressure is a tangential force and friction is a normal force. Based on this, the force sensor 23 is preferably a multi-axis force sensor to collect forces from different directions on the contact surface between the cooking pot 3 and the pot support 2. It is also possible to set a pressure sensor 23 and a friction sensor 23 to collect forces in two directions, and the specific configuration is based on the force state of the cooking pot 3 in the actual application scenario. In this embodiment, the acquisition frequency of the force sensor 23 is set to 500 Hz (hertz), and it can also be greater than 500 Hz. The larger the frequency value, the higher the acquisition frequency (i.e., the sampling rate).

[0063] In one embodiment, for the determination of the pre-sliding state of the pot, step S102 specifically includes: when the ratio of the friction force to the pressure of any one foot piece is greater than or equal to a first preset threshold, it is determined that the state of the cooking pot is the pre-sliding state of the pot.

[0064] Among them, the first preset threshold is determined according to the coefficient of static friction (i represents the data corresponding to the i-th foot piece), and is generally set to 0.9 times the coefficient of static friction , so as to provide sufficient time for the cooking pot support 2 to make adjustments and prevent the cooking pot 3 from slipping. In other words, when the friction force of any one foot piece 21 is greater than 0.9* times the pressure, that is , it can be determined that the state of the cooking pot is the pre-sliding state of the pot.

[0065] In a specific embodiment, step S103 specifically includes: when the state of the cooking pot is the pre-sliding state of the pot, determine the target foot piece in the cooking pot support. The target foot piece is the foot piece corresponding to the maximum pressure among at least one foot piece, and adjust the height of the target foot piece.

[0066] Specifically, according to the pressure { } of all foot pieces 21 in the sensing data set, find the foot piece 21 corresponding to the maximum pressure Max{ }, and start the micro-motor connected to the foot piece 21 to raise the height of the foot piece 21. During the adjustment process, the height of the foot piece 21 can be directly adjusted to the first preset height; or the preset height of the foot piece 21 can be adjusted multiple times in small increments, and after each adjustment, return to step S101 to cycle and determine the state of the cooking pot, and stop the adjustment after determining that the state of the cooking pot is not in the pre-sliding state of the pot. For example, each time the height of the foot piece 21 is raised by 1 mm. During this process, the center of gravity of the cooking pot can be adjusted, and precise adjustment of the foot piece 21 can be achieved through multiple small increments of height adjustment, preventing the pot from slipping and realizing active intervention.

[0067] In one embodiment, for the determination of the pot-sliding state, pot-lifting state, and pot-tossing state, the method further includes: obtaining the acceleration of the cooking pot.

[0068] Among them, the acceleration of the cooking pot 3 can be collected by the acceleration sensor 31 on the handle of the cooking pot 3. The acceleration sensor 31 usually collects the acceleration of the cooking pot 3 in the horizontal direction (ignoring the vertical direction ), and the acceleration vector amplitude . The sampling frequency is set to 500 Hz (Hertz), or can be greater than 500 Hz. The larger the frequency value, the higher the acquisition frequency (i.e., the sampling rate).

[0069] On this basis, step S102 may further include: determining the state of the cookware according to the contact force of any one of the feet and the acceleration of the cookware.

[0070] In a specific embodiment, the conditions for determining that the state of the cookware in step S102 is a sliding cookware state include at least one of the following:

[0071] First, the change value of the friction force of the foot within the first preset time duration is greater than the second preset threshold. At this time, the friction force between the cookware 3 and the foot 21 drops suddenly, and the stable state of the cookware 3 on the cookware support 2 is broken. Specifically, ( represents the change value of the i-th friction force represents the change value, characterizes the first preset time duration, characterizes the second preset threshold). For example, is 10 ms, is -8 N / s (Newton per second). When the friction force drops by more than 8 N within 10 ms, it can be considered that the state of the cookware is in a sliding cookware state. The settings of the first preset time duration and the second preset threshold can be selected according to the actual situation and are not limited to the examples in this embodiment.

[0072] Second, the ratio of the friction force and the pressure of the foot is less than the third preset threshold. At this time, the friction coefficient between the foot 21 and the cookware 3 drops suddenly, and the balance state between the friction force and the pressure of the cookware 3 and the cookware support 2 is broken. Specifically, ( is the friction force corresponding to the i-th foot, is the pressure corresponding to the i-th foot, is the third preset threshold), where the third preset threshold is set according to the static friction coefficient. In this embodiment, is set to 0.6 ( is the static friction coefficient corresponding to the i-th foot), but it is not limited to this and can be selected according to the actual situation.

[0073] Third, the change value of the pressure of the foot within the first preset time duration is greater than the fourth preset threshold. At this time, the pressure between the cookware 3 and the foot 21 drops suddenly, and the stable state of the cookware 3 on the cookware support 2 is broken. Specifically, ( is the pressure of the i-th foot at the current time node, is the pressure of the i-th foot at the previous time node, is the fourth preset threshold). For example, is 0.4, that is, when the pressure of a certain foot piece drops instantaneously by more than 40%, it can be considered that the state of the cookware is in a skidding state. The setting of the fourth preset threshold can be selected according to the actual situation and does not have to be limited to the examples in this embodiment.

[0074] Fourth, the direction feature of the acceleration shifts in one direction and exceeds the second preset duration. At this time, the cookware 3 shifts in one direction. Specifically, the direction feature of the acceleration can be characterized by the acceleration vector amplitude ( calculated), for example, , the second preset duration is 0.2 s, and there is no significant main frequency of the acceleration. It can be considered that the cookware 3 is in a skidding state. The setting of the second preset duration can be selected according to the actual situation and does not have to be limited to the examples in this embodiment.

[0075] In order to make the judgment of the skidding state more accurate, the four conditions in the above embodiment can be combined and used to determine the skidding state at the same time.

[0076] In a specific embodiment, regarding the adjustment method of the cookware support in the skidding state, step S103 specifically includes:

[0077] When the state of the cookware is in the skidding state, the heights of all the foot pieces on the cookware support are adjusted. For example, the heights of all the foot pieces 21 can be adjusted to the first preset height to facilitate the user to place the slipping cookware 3 back on the cookware support 2.

[0078] In addition, in the adjustment method in the skidding state, it can also be linked with the gas valve of the gas stove, such as automatically extinguishing the fire or reducing the firepower, etc., to avoid safety hazards such as gas leakage and fire caused by the skidding state.

[0079] In a specific embodiment, the conditions for determining that the state of the cookware is in the flipping state in step S102 include at least one of the following:

[0080] First, the friction force of the foot piece fluctuates periodically within the third preset duration. At this time, the friction force between the cookware 3 and the foot piece 21 fluctuates periodically. For example, shows a sine / sine-like fluctuation within the third preset duration, and the change rate is symmetrically distributed. Among them, the third preset duration is 0.5 s. The setting of the third preset duration can be selected according to the actual situation and does not have to be limited to the examples in this embodiment.

[0081] Second, the direction feature of the acceleration changes alternately in multiple directions. For example, the direction feature shows a reciprocating change along the X / Y axis.

[0082] In order to make the judgment of the flipping state more accurate, the four conditions in the above embodiments can be combined and used, and can also be used simultaneously to determine the flipping state.

[0083] In a specific embodiment, regarding the adjustment method of the cookware support for the flipping state, step S103 specifically includes:

[0084] When the cookware state is the flipping state, the height of all the foot pieces 21 on the cookware support 2 is adjusted. For example, the height of all the foot pieces 21 can be adjusted to a first preset height, so as to facilitate the user to place the cookware 3 after flipping back on the cookware support 2.

[0085] In a specific embodiment, the conditions for determining that the cookware state is the lifting state in step S102 include: the pressure of all the feet 1 on the cookware support is 0.

[0086] In a specific embodiment, regarding the adjustment method of the cookware support for the lifting state, step S103 specifically includes:

[0087] When the cookware state is the lifting state, the height of all the foot pieces on the cookware support is adjusted. For example, the height of all the foot pieces 21 can be adjusted to a first preset height, so as to facilitate the user to place the lifted cookware 3 back on the cookware support 2.

[0088] In addition, in the adjustment method for the lifting state, it can also be linked with the gas valve of the gas stove, such as automatically extinguishing the fire or reducing the firepower, etc., to avoid safety hazards such as gas leakage and fire caused by the lifting state.

[0089] One exemplary embodiment of the present disclosure provides a gas stove. Refer to Figure 2 and Figure 3 , the gas stove includes a burner 4 and a cookware support 2. The cookware support 2 includes at least one foot piece 21 surrounding the burner 4, each foot piece 21 is used to support the cookware 3, and a force sensor 23 is installed at the position where each foot piece 21 contacts the cookware 3, and the force sensor 23 is used to collect the contact force between each foot piece 21 and the cookware 3.

[0090] The cookware support 2 is used to be adjusted according to the adjustment method of the cookware support 2 in the above embodiments. Specifically, the cookware support 2 further includes a base 22, and each foot piece 21 is connected to the base 22 through a shaft rod, and the lifting of the shaft rod is realized by a micro motor, so as to realize the lifting of the foot piece 21.

[0091] In one embodiment, an acceleration sensor 31 is further provided on the cookware 3, and the acceleration sensor 31 is used to collect the acceleration of the cookware 3, specifically the acceleration in the horizontal direction.
