Description

Technical Field

[0001] The present invention relates to the technical field of gas valves, and in particular to an AI intelligent gas valve control method, system and AI intelligent gas valve. Background Art

[0002] A gas valve is a device used to cut off, connect and regulate the gas in a pipeline, and has good control characteristics and closing and sealing performance.

[0003] A gas valve generally includes components such as a valve body, a valve stem and a valve core. The valve body is generally made of copper or steel, has good pressure resistance and corrosion resistance, and can withstand the high pressure brought by the gas in the pipeline. The valve stem is arranged on the valve body and can rotate on the valve body. The valve body is connected to the pipeline transporting gas, and a cavity through which gas can pass is provided in the valve body. The valve core is arranged on the valve stem, and the valve stem is used to control the opening and closing action of the valve core to facilitate user operation. The valve core is used to improve the sealing performance of the gas valve and is arranged in the cavity of the valve body in cooperation with the valve stem. When the gas valve is closed, the valve core fits tightly with the valve body to prevent gas leakage. When the gas valve is opened, the user rotates the valve stem to drive the valve core to rotate, so that the gas can pass through the cavity and the pipeline to be transported to the gas stove, and the user presses and turns the switch of the gas stove to ignite the gas to generate a flame for use.

[0004] When the user manually opens and closes the gas valve, since the gas is not likely to leak when the switch of the gas stove is closed, the gas valve does not need to be continuously opened and closed. In the daily use process, when the gas stove is frequently used, it is easy to occur that the gas stove is in an open state but the fire is not ignited. At this time, if the gas valve is not closed, gas leakage is likely to occur and cause harm to the human body, which needs to be improved. Summary of the Invention

[0099] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0100] An AI intelligent gas valve control method remotely identifies the user's operation of the gas stove through images, and makes real-time adjustments through the intelligent gas valve according to the switch on the gas stove, kitchen utensils, the usage time of the gas stove, and the flame situation generated on the gas stove, so as to realize the automatic opening and closing of the gas valve and improve the safety of gas use.

[0101] Refer to Figure 1 , an AI intelligent gas valve control method is disclosed in the embodiment of the present application, including the following steps:

[0102] Step S100: When the intelligent gas valve receives the preset trigger information, obtain the image detection information of the gas stove.

[0103] The trigger information refers to the information triggered by the user pressing the switch for ignition on the gas stove. The signal output by the micro touch controller preset in the gas stove switch by the operator is used as the trigger information. The micro touch controller is a device that outputs an electrical signal when the gas stove is powered on to make the intelligent gas valve know that the user needs to use the gas stove. The image detection information refers to the image corresponding to the gas stove. When the intelligent gas valve receives the preset trigger information, it means that the user starts to use the gas stove. Therefore, the image of the gas stove is taken by the micro camera preset on the AI intelligent gas valve as the image detection information. The intelligent gas valve is a device used to remotely control the opening and closing of the valve to control the output of gas. The intelligent gas valve includes a power supply component for providing electrical energy, an electromagnetic valve, and a control device for outputting a current signal to control the opening and closing of the electromagnetic valve. The electromagnetic valve is used to receive the current signal output by the control device to open and close, so as to control the situation of gas output to the gas stove through the opening and closing of the electromagnetic valve. The intelligent gas valve is generally installed on the walls on both sides of the gas stove along the length direction to facilitate the analysis and detection of the switch of the gas stove and the objects around the gas stove.

[0104] Step S101: Based on the image detection information, frame the image corresponding to the preset switch feature, and use the framed image as the switch image.

[0105] The switch feature refers to the installation position, shape, and other features corresponding to the ignition switch on the gas stove. The switch feature is preset by those skilled in the art and will not be elaborated here. The switch image refers to the image corresponding to the ignition switch on the gas stove. By selecting the image corresponding to the preset switch feature from the image detection information and using the selected image as the switch image.

[0106] Step S102: Input the switch image into a preset angle model to output the rotation angle.

[0107] The angle model refers to a model that has been pre-trained by inputting the switch image through a neural network and is used to output the angle information of the rotation of the switch. The angle model is preset by those skilled in the art and will not be elaborated here. The rotation angle refers to the angle of rotation corresponding to the ignition switch on the gas stove. By inputting the switch image into the angle model to output the rotation angle.

[0108] Step S103: Based on the rotation angle, input it into a preset gas database to match the actual gas output of the intelligent gas valve.

[0109] The actual gas output refers to the gas output required by the intelligent gas valve. By inputting the rotation angle into the preset gas database to match the actual gas output. Different rotation angles corresponding to the actual gas output are stored in the gas database. The gas database is a database set by humans and will not be elaborated here.

[0110] Step S104: Determine the output current of the intelligent gas valve based on the reference intake volume.

[0111] The output current refers to the current output by the control device during the operation of the intelligent gas valve. By using the reference intake volume to match the output current from the preset current database. Different actual gas outputs corresponding to the output current are stored in the current database. The current database is a database set by humans and will not be elaborated here. When the rotation angle is 0, the output current can be 0.

[0112] Step S105: Output the output current to a control device preset in the intelligent gas valve to control the opening and closing of the intelligent gas valve.

[0113] By operating with the output current through the control device, the opening and closing of the intelligent gas valve can be realized. Furthermore, the opening and closing of the gas valve can be remotely controlled according to the usage situation of the gas stove. It is not easy to cause gas leakage when the gas valve is not closed, which may pose a hazard to the human body, thus improving the safety of gas use.

[0114] Refer to Figure 2 , the method before controlling the opening and closing of the intelligent gas valve further includes:

[0115] Step S200: Obtain the surrounding image information of the gas stove and the historical usage time of the intelligent gas valve.

[0116] The surrounding image information refers to the images around the gas stove. The images of the surroundings of the gas stove are captured by a micro camera preset on the intelligent gas valve as the surrounding image information. The historical usage time refers to the time points corresponding to the opening and closing of the intelligent gas valve in the historical period, and the time points corresponding to the opening and closing of the intelligent gas valve in the historical period are retrieved from the system as the historical usage time.

[0117] Step S201: When preset human features appear in the surrounding image information, based on the surrounding image information, frame the image corresponding to the human features, and use the framed image as the human image information.

[0118] Human features refer to features such as the shape and color corresponding to a person. The human features are set in advance by those skilled in the art and will not be elaborated here. The human image information refers to the image of the person corresponding to the surrounding image information. When human features appear in the surrounding image information, it indicates a high probability that the user is using the gas stove. Therefore, the image corresponding to the human features is framed from the surrounding image information, and the framed image is used as the human image information.

[0119] Step S202: Determine different historical usage time periods according to the historical usage time.

[0120] The historical usage time period refers to the time period corresponding to the usage of the intelligent gas valve in the historical period, and two time points corresponding to the opening and closing of the intelligent gas valve are combined to form the historical usage time period.

[0121] Step S203: Determine the estimated usage time period according to the overlapping situation of different historical usage time periods.

[0122] The estimated usage time period refers to the estimated time period corresponding to the frequent use of the gas stove. By comparing the overlap of different historical usage time periods, each time period formed after the overlap is used as the estimated usage time period.

[0123] Step S204: Based on the surrounding image information, mark the time point corresponding to the human image information.

[0124] The marked time point refers to the time point corresponding to the appearance of the human image information in the surrounding image information. When the human image information appears in the surrounding image information, the current time is marked, and the marked time point is used as the marked time point.

[0125] Step S205: Determine whether the marked time point falls within the estimated usage time period.

[0126] By determining whether the marked time point falls within the estimated usage time period, it is determined whether the user needs to use the gas stove at the current time.

[0127] Step S206: When the marked time point falls within the estimated usage time period, directly output the output current to the control device until no human features appear in the surrounding image information.

[0128] When the marked time point falls within the estimated usage time period, it indicates that the user needs to use the gas stove. Therefore, the output current is directly output to the control device until no human features appear in the surrounding image information, so that the user can directly start the switch on the gas stove to successfully ignite the gas stove. Furthermore, when the user presses the switch on the gas stove, the gas can be directly transported from the intelligent gas valve to the gas valve to achieve ignition.

[0129] Step S207: When the marked time point does not fall within the estimated usage time period, based on the human image information, frame the position corresponding to the preset hand feature as the hand position.

[0130] The hand feature refers to the shape, color, and other features of the hand corresponding to the person. The hand feature is set in advance by those skilled in the art and will not be elaborated here. The hand position refers to the position of the hand corresponding to the user. When the marked time point does not fall within the estimated usage time period, it indicates that the probability of the user needing to use the gas stove is low. Therefore, the position of the image corresponding to the hand feature is framed from the human image information as the hand position.

[0131] Step S208: Update the hand position according to the preset unit time, and determine the hand movement direction based on the hand positions before and after the update.

[0132] The unit time refers to the time parameter value used to know the movement of the user's hand. The unit time is set in advance by those skilled in the art and will not be elaborated here. The hand position is updated in real time through the unit time, and the vector distance between the hand positions before and after the update is calculated, and the direction parameter is retrieved from the vector distance as the hand movement direction.

[0133] Step S209: Determine the reference movement direction according to the updated hand position and the preset switch position.

[0134] The switch position refers to the position where the switch for ignition on the gas stove is located. The switch position is set in advance by those skilled in the art and will not be elaborated here. The reference movement direction refers to the reference direction of the hand movement when the user needs to use the gas stove. By calculating the vector distance between the updated hand position and the switch position, and retrieving the direction parameter from the vector distance as the reference movement direction.

[0135] Step S210: When the moving direction of the hand is consistent with the reference moving direction, output current to the control device until no human features appear in the surrounding image information.

[0136] When the moving direction of the hand is inconsistent with the reference moving direction, it indicates that the user does not need to use the gas stove, so continue to obtain the surrounding image information. When the moving direction of the hand is consistent with the reference moving direction, it indicates that the user needs to use the gas stove, so directly output current to the control device until no human features appear in the surrounding image information, so that the user can directly start the switch on the gas stove to successfully ignite the gas stove. Furthermore, when the user presses the switch on the gas stove, the gas can be directly transported from the intelligent gas valve to the gas valve to achieve ignition.

[0137] Refer to Figure 3 , the method after controlling the opening and closing of the intelligent gas valve includes:

[0138] Step S300: When the intelligent gas valve is opened, based on the image detection information, frame the shape corresponding to the preset kitchenware features, and use the framed shape as the kitchenware shape.

[0139] Kitchenware features refer to the shape, color, etc. of the kitchenware corresponding to the one that needs to be placed on the gas stove, which are formed by the operator's preset and storage in advance. Kitchenware shape refers to the shape of the kitchenware placed on the gas stove. When the intelligent gas valve is opened, frame the shape corresponding to the kitchenware features from the image detection information, and use the framed shape as the kitchenware shape.

[0140] Step S301: Input the kitchenware shape into the preset kitchenware database to match the kitchenware type.

[0141] Kitchenware type refers to the type of the kitchenware corresponding to the kitchenware shape. By inputting the kitchenware shape into the preset kitchenware database for comparison to match the kitchenware type. Different kitchenware types corresponding to different kitchenware shapes are stored in the kitchenware database. The kitchenware database is a database set by humans and will not be elaborated here. Kitchenware types include the types corresponding to kitchenware such as frying pans and pressure cookers.

[0142] Step S302: When the kitchenware type is a pressure cooker, determine the estimated water vapor generation range according to the kitchenware shape.

[0143] When the kitchenware type is a pressure cooker, the estimated water vapor generation range refers to the estimated range of the water vapor generated by the pressure cooker. By retrieving the air outlet point of the pressure cooker from the kitchenware shape corresponding to the pressure cooker, and using the estimated range of the kitchenware shape corresponding to the air outlet point as the estimated water vapor generation range.

[0144] Step S303: Determine the reference image information when the intelligent gas valve is not operating according to the image detection information and the kitchenware type.

[0145] The reference image information refers to the image of the pressure cooker placed on the gas stove when the intelligent gas valve is not operating. The image corresponding to the type of cooking utensil on the gas stove when the intelligent gas valve is not operating is retrieved from the image detection information as the reference image information.

[0146] Step S304: Based on the image detection information, the image corresponding to the estimated water vapor generation range is selected by frame selection as the water vapor output image.

[0147] The water vapor output image refers to the image of the water vapor generated by the pressure cooker when the intelligent gas valve is operating. The image corresponding to the estimated water vapor generation range is selected by frame selection from the image detection information as the water vapor output image.

[0148] Step S305: The water vapor output image and the reference image information are input into a preset image processing database to match the actual clarity.

[0149] The actual clarity refers to the actual clarity corresponding to the water vapor output image when water vapor appears on the pressure cooker. The water vapor output image and the reference image information are input into a preset image processing database to match the actual clarity. Different water vapor output images stored in the image processing database correspond to the clarity based on the reference image information. The image processing database is a database set by humans and will not be elaborated here.

[0150] Step S306: When the actual clarity reaches the preset reference water vapor clarity, the reference adjusted current is output to the control device according to the preset to control the operation of the intelligent solenoid valve.

[0151] The reference water vapor clarity refers to the reference clarity of the water vapor output image corresponding to when the gas volume of the pressure cooker on the gas stove needs to be reduced. The reference water vapor clarity is set in advance by those skilled in the art and will not be elaborated here. The reference adjusted current refers to the minimum current output by the corresponding control device after adjustment. The reference adjusted current is set in advance by those skilled in the art and will not be elaborated here. When the actual clarity reaches the reference water vapor clarity, it indicates that the gas volume of the pressure cooker on the gas stove needs to be reduced. Therefore, the reference adjusted current is output to the control device to control the operation of the intelligent solenoid valve, so that the gas volume output by the intelligent solenoid valve can be controlled according to the usage situation of the cooking utensils on the gas stove.

[0152] Refer to Figure 4 , the method after controlling the opening and closing of the intelligent gas valve further includes:

[0153] Step S400: When the intelligent gas valve is opened, the weight detection value corresponding to the type of cooking utensil is obtained.

[0154] The weight detection value refers to the weight value corresponding to the kitchen utensils on the gas stove. When the intelligent gas valve is opened, the parameter detected by the pressure sensor preset on the gas stove is used as the weight detection value.

[0155] Step S401: Retrieve the reference weight value based on the type of kitchen utensils.

[0156] The reference weight value refers to the reference weight value when the corresponding pot lid is covered on the kitchen utensils. The reference weight value is retrieved from the type of kitchen utensils.

[0157] Step S402: Determine whether the weight detection value is greater than the reference weight value.

[0158] By determining whether the weight detection value is greater than the reference weight value, it is determined whether there are item materials placed inside the kitchen utensils with the pot lid covered.

[0159] Step S403: If the weight detection value is greater than the reference weight value, calculate the difference between the weight detection value and the reference weight value as the pressure deviation value.

[0160] The pressure deviation value refers to the deviation value between the weight detection value and the reference weight value. When the weight detection value is greater than the reference weight value, it means that the pot lid is not covered on the kitchen utensils or there are item materials placed when the pot lid is not covered on the kitchen utensils, so the weight detection value is continuously obtained. When the weight detection value is greater than the reference weight value, it means that there are item materials placed inside the kitchen utensils with the pot lid covered, so calculate the difference between the weight detection value and the reference weight value and use the difference as the pressure deviation value.

[0161] Step S404: When the pressure deviation value does not exceed the preset reference deviation value, determine whether the rotation angle is zero.

[0162] The reference deviation value refers to the reference value of the deviation when there is water stain inside the kitchen utensils with the pot lid covered. The reference deviation value is set in advance by those skilled in the art and will not be elaborated here. When the pressure deviation value exceeds the reference deviation value, it means that there is water stain inside the kitchen utensils with the pot lid covered, so the weight detection value is continuously obtained. When the pressure deviation value does not exceed the reference deviation value, it means that there are no item materials placed inside the kitchen utensils with the pot lid covered, so determine whether the rotation angle is zero to determine whether the gas stove is turned on.

[0163] Step S405: When the rotation angle is not zero, output the preset stop control information to the control device to control the intelligent solenoid valve to stop operating.

[0164] The stop control information refers to the information corresponding to making the control device stop outputting current, which is preset by those skilled in the art and will not be elaborated here. When the rotation angle is zero, it indicates that the gas stove is not started, so the weight detection value is continuously obtained. When the rotation angle is not zero, it indicates that the gas stove is started, so the preset stop control information is output to the control device to control the intelligent solenoid valve to stop operating, so that it is not easy for users to control the gas stove to turn on when there are no item materials placed on the kitchenware, thereby improving the safety during the use of the gas stove.

[0165] Referring to Figure 5 , the method after controlling the opening and closing of the intelligent gas valve further includes:

[0166] Step S500: When the intelligent gas valve is opened, obtain the flame image information on the gas stove.

[0167] The flame image information refers to the image of the flame generated by the gas stove. When the intelligent gas valve is opened, it indicates that a flame will be generated on the gas stove, so the image detection information is used as the flame image information.

[0168] Step S501: Based on the flame image information, frame the shape corresponding to the preset flame feature, and use the framed shape as the flame shape.

[0169] The flame feature refers to features such as the color and shape corresponding to the flame generated on the gas stove. The flame feature is preset by those skilled in the art and will not be elaborated here. The flame shape refers to the shape corresponding to the flame generated on the gas stove. By framing the shape corresponding to the flame feature from the flame image information and using the framed shape as the flame shape.

[0170] Step S502: Match the reference flame shape from the preset combustion database according to the output current.

[0171] The reference flame shape refers to the reference shape of the flame generated by the gas stove under the control of the output current of the intelligent gas valve. The reference flame shape is matched from the preset combustion database according to the output current. Different flame shapes corresponding to different output currents are stored in the combustion database. The combustion database is a database set by humans and will not be elaborated here.

[0172] Step S503: Determine whether the flame shape is consistent with the reference flame shape. If it is, jump to execute Step S504. If not, jump to execute Step S505.

[0173] By determining whether the flame shape is consistent with the reference flame shape, it is determined whether the intelligent gas valve and the gas stove are abnormal.

[0174] Step S504: Continuously obtain the flame image information.

[0175] When the flame shape is consistent with the reference flame shape, it indicates that there is no abnormality in the intelligent gas valve and the gas stove, so the flame image information is continuously acquired.

[0176] Step S505: Determine the abnormal device according to the flame shape and the reference flame shape.

[0177] The abnormal device refers to the device corresponding to the abnormality in the intelligent gas valve or the gas stove. The abnormal device is obtained by analyzing the flame shape and the reference flame shape.

[0178] Step S506: When the abnormal device is the intelligent gas valve, determine the combustion range according to the flame shape and determine the reference combustion range according to the reference flame shape.

[0179] The combustion range refers to the range corresponding to the combustion of the flame shape, and the reference combustion range refers to the range corresponding to the reference flame shape. When the abnormal device is the intelligent gas valve, it indicates that there is an abnormality in the components of the intelligent gas valve. Therefore, the circumferential range corresponding to the flame shape is used as the combustion range, and the circumferential range corresponding to the reference flame shape is used as the reference combustion range.

[0180] Step S507: When the combustion range is smaller than the reference combustion range, calculate the estimated usage time according to the historical usage time.

[0181] When the combustion range is larger than the reference combustion range, it indicates that there is an abnormality in the solenoid valve, so the preset warning information is output. The warning information refers to the information used to prompt the user that there is an abnormality in the intelligent gas valve. The warning information is preset by those skilled in the art and will not be elaborated here. The estimated usage time refers to the estimated time parameter value when the intelligent gas valve is used. When the combustion range is smaller than the reference combustion range, it indicates that the probability of an abnormality in the power supply component is high. Therefore, the time points corresponding to the continuous historical usage time when the intelligent gas valve is turned on are retrieved from the system, and the differences between the time points corresponding to each continuous historical usage time are calculated. The average value corresponding to all the differences is used as the estimated usage time.

[0182] Step S508: Match the actual output current from the preset combustion database according to the flame shape.

[0183] The actual output current refers to the current actually output by the intelligent gas valve when the gas stove outputs the flame shape. The actual output current is matched from the combustion database according to the flame shape. Different output currents corresponding to different flame shapes are stored in the combustion database. The combustion database is preset by those skilled in the art and will not be elaborated here.

[0184] Step S509: Determine the estimated usage electrical energy according to the estimated usage time and the actual output current.

[0185] The estimated power consumption refers to the power that the gas stove needs to consume during the estimated usage time. The parameter calculated through the formula for electric energy using the estimated usage time, the actual output current, and the preset reference voltage is used as the estimated power consumption. The formula for electric energy is common knowledge in the art and will not be elaborated here. The reference voltage refers to the voltage corresponding to the use of the intelligent gas valve, which is set in advance by those skilled in the art and will not be elaborated here.

[0186] Step S510: Obtain the actual stored electric energy of the intelligent gas valve.

[0187] The actual stored electric energy refers to the electric energy actually stored in the power supply component in the intelligent gas valve, and the electric energy parameter corresponding to the power supply component is retrieved from the system as the actual stored electric energy.

[0188] Step S511: Determine whether the actual stored electric energy is greater than the estimated power consumption.

[0189] By determining whether the actual stored electric energy is greater than the estimated power consumption, it is determined whether the current output of the intelligent gas valve decreases due to insufficient electric energy.

[0190] Step S512: When the actual stored electric energy is greater than the estimated power consumption, obtain the ambient temperature value around the intelligent gas valve.

[0191] The ambient temperature value refers to the temperature value of the environment around the intelligent gas valve. When the actual stored electric energy is greater than the estimated power consumption, it indicates that there is no situation where the current output of the intelligent gas valve decreases due to insufficient electric energy. Therefore, the parameter detected by the temperature sensor preset in the intelligent gas valve is used as the ambient temperature value.

[0192] Step S513: When the ambient temperature value is greater than the preset reference temperature value, output the preset temperature adjustment prompt message to adjust the temperature around the intelligent gas valve.

[0193] The reference temperature value refers to the maximum temperature value that does not affect the magnetic force generated by the solenoid valve, which is formed after being preset and stored by the operator. When the ambient temperature value is not greater than the reference temperature value, it indicates that the temperature of the environment around the intelligent gas valve does not affect the magnetic force generated by the solenoid valve. Therefore, continue to obtain the ambient temperature value.

[0194] The temperature adjustment prompt message refers to the information temperature used to prompt the user to adjust the temperature around the intelligent gas valve. The adjustment prompt message is set in advance by those skilled in the art and will not be elaborated here. When the ambient temperature value is greater than the reference temperature value, it indicates that the temperature of the environment around the intelligent gas valve affects the magnetic force generated by the solenoid valve. Therefore, output the preset temperature adjustment prompt message to prompt the user to ventilate, thereby adjusting the temperature around the intelligent gas valve.

[0195] Step S514: When the actually stored electric energy is not greater than the estimated used electric energy, output a preset electric energy replenishment prompt message.

[0196] The electric energy replenishment prompt message refers to the information used to prompt the user to replace the power source. The electric energy warning information is preset by those skilled in the art and will not be elaborated here. When the actually stored electric energy is not greater than the estimated used electric energy, it indicates that the current output of the intelligent gas valve decreases due to insufficient electric energy. Therefore, a preset electric energy replenishment prompt message is output to prompt the user to replace the power source.

[0197] Refer to Figure 6 , the method after determining the abnormal device further includes:

[0198] Step S600: When the abnormal device is located at the gas stove, based on the type of kitchenware, retrieve the shape of the bottom of the kitchenware as the bottom shape.

[0199] The bottom shape refers to the shape corresponding to the bottom of the kitchenware. When the abnormal device is located at the gas stove, it indicates that there are abnormalities such as gas blockage at the flame outlet of the gas stove. Therefore, the shape of the bottom of the kitchenware is retrieved from the type of kitchenware as the bottom shape.

[0200] Step S601: Determine the bottom fitting range according to the bottom shape and the flame shape.

[0201] The bottom fitting range refers to the range where the flame shape fits the bottom of the kitchenware. The bottom fitting range is matched from the combustion database through the bottom shape and the flame shape. The combustion database also stores the bottom fitting ranges corresponding to different bottom shapes and flame shapes, which will not be elaborated here.

[0202] Step S602: Determine different bottom fitting radii according to the bottom fitting range and the preset reference center line.

[0203] The reference center line refers to the center line corresponding to the flame outlet of the gas stove. The reference center line is preset by those skilled in the art and will not be elaborated here. The bottom fitting radius refers to the radius where the flame fits the bottom of the kitchenware based on the reference center line. The horizontal straight-line distances between the center point corresponding to the reference center line and each point in the bottom fitting range are calculated as the bottom fitting radii.

[0204] Step S603: Arrange the different bottom fitting radii in reverse order, select the smallest bottom fitting radius as the combustion deviation radius, and select the largest bottom fitting radius as the reference flame radius.

[0205] The combustion deviation radius refers to the deviation radius where the flame adheres to the bottom of the cooking utensil when the gas outlet of the gas stove is blocked, and the reference flame radius refers to the reference radius where the flame adheres to the bottom of the cooking utensil when the gas stove burns with the reference flame shape. By arranging different bottom adhesion radii in reverse order and selecting the smallest bottom adhesion radius as the combustion deviation radius, and selecting the largest bottom adhesion radius as the reference flame radius.

[0206] Step S604: Calculate the difference between the combustion deviation radius and the reference flame radius and use it as the radius deviation value.

[0207] The radius deviation value refers to the deviation value between the combustion deviation radius and the reference flame radius. By calculating the difference between the combustion deviation radius and the reference flame radius and using the difference as the radius deviation value.

[0208] Step S605: Determine the gas blockage position according to the radius deviation value and the flame shape.

[0209] The gas blockage position refers to the position where the gas outlet of the gas stove is blocked. By taking the position corresponding to the radius deviation value in the flame shape as the gas blockage position.

[0210] Step S606: Output a preset blockage prompt message according to the gas blockage position.

[0211] The blockage prompt message refers to the information used to prompt the user that the gas outlet of the gas stove is blocked. The blockage prompt message is preset by those skilled in the art and will not be elaborated here. By outputting the blockage prompt message to prompt the user to clean the gas stove in time, so as to be able to timely understand the abnormal situation of the gas stove and prompt for handling, thereby improving the safety of using the gas stove.

[0212] The method after outputting the preset blockage prompt message:

[0213] Step S700: When the intelligent gas valve is operating, match the rotation speed corresponding to the ignition device preset on the gas stove from the preset rotation database according to the type of cooking utensil and the output current.

[0214] The ignition device refers to the device on the gas stove that generates an electric spark to ignite the gas and produce a flame. The ignition device can be an ignition needle or a spark plug. The rotation speed refers to the speed corresponding to the rotation of the ignition device. The rotation speed is matched from a preset rotation database based on the type of kitchenware and the output current. The rotation database stores the rotation speeds corresponding to different types of kitchenware and output currents. A motor and a driving gear are provided inside the gas stove. The ignition device includes an ignition needle for forming an electric spark and an air outlet cover provided with air outlet holes. A mating gear that cooperates with the driving gear is provided below the air outlet cover. The driving gear is rotated by the motor to drive the mating gear to rotate simultaneously, and the air outlet cover rotates circumferentially through the rotation of the mating gear, so that the flame can evenly burn the bottom of the kitchenware.

[0215] Step S701: Calculate the adjusted current based on the output current and the rotation speed.

[0216] The adjusted current refers to the current output by the control device after adjustment. The adjusted current is calculated by inputting the output current and the rotation speed into a preset calculation method for the adjusted current.

[0217] Calculation method for the adjusted current: I2 = I1 / (A × V2 + B × V + C), where I2 is the adjusted current, I1 is the output current, V is the rotation speed, and A, B, and C are parameters obtained by the operator through prior experiments.

[0218] Step S702: Determine the rotational centrifugal force based on the rotation speed and the reference flame radius.

[0219] The rotational centrifugal force refers to the centrifugal force generated by the flame when the ignition device rotates. The rotational centrifugal force is matched from a preset centrifugal force database based on the rotation speed and the reference flame radius. The centrifugal force database stores the rotational centrifugal forces corresponding to different rotation speeds and reference flame radii.

[0221] The flame increase distance refers to the increased radius distance required for the reference combustion range when the air outlet cover rotates. The flame increase distance is matched from the centrifugal force database based on the rotational centrifugal force. The centrifugal force database stores the flame increase distances corresponding to different rotational centrifugal forces and will not be elaborated here.

[0222] Step S704: Update the adjusted current based on the flame increase distance.

[0223] When there is an increase in the flame distance, the range of the fit between the flame and the cooking utensil increases, indicating that the efficiency of heat transfer from the flame to the cooking utensil increases. Therefore, a correction factor is matched from the combustion database based on the increased flame distance, and the product value between the correction factor and the adjusted current is calculated, and the product value is used as the new adjusted current.

[0224] Step S705: Control the operation of the intelligent gas valve according to the updated adjusted current, and control the rotation of the ignition device preset on the gas stove according to the rotation speed.

[0225] Control the operation of the intelligent gas valve through the updated adjusted current, and control the rotation of the ignition device driven by the motor through the rotation speed, so that the heat transferred by the flame corresponding to the rotating ignition device is consistent with the heat transferred by the flame corresponding to the output current.

[0226] Further, the method before outputting the preset electric energy supplement prompt information includes:

[0230] The actual combustion range refers to the range of combustion corresponding to the actual flame shape. The circumferential range corresponding to the actual flame shape is used as the actual combustion range.

[0232] The actual combustion radius refers to the radius at which the flame corresponding to the actual combustion range fits the bottom of the cooking utensil. The horizontal straight-line distance between the center point corresponding to the reference center line and the actual combustion range is calculated as the actual combustion radius.

[0233] Step S5144: Calculate the difference between the actual combustion radius and the reference flame radius and use it as the supplementary deviation value.

[0234] The supplementary deviation value refers to the deviation value of the radius corresponding to the flame that needs to be supplemented for combustion. The difference between the actual combustion radius and the reference flame radius is calculated, and the difference value is used as the supplementary deviation value.

[0235] Step S5145: Input the supplementary deviation value into a preset centrifugal force database to match the supplementary centrifugal force.

[0236] The supplementary centrifugal force refers to the centrifugal force corresponding to the rotation of the gas outlet cover required for supplementary combustion. By inputting the supplementary deviation value into the centrifugal force database to match the supplementary centrifugal force, different supplementary centrifugal forces corresponding to different supplementary deviation values are stored in the centrifugal force database, which will not be elaborated here.

[0237] Step S5146: Determine the adjusted rotation speed based on the supplementary centrifugal force and the reference flame radius, and control the rotation of the ignition device according to the adjusted rotation speed.

[0238] The adjusted rotation speed refers to the rotation speed of the gas outlet holes after adjustment. The adjusted rotation speed is matched from the centrifugal force database based on the supplementary centrifugal force and the reference flame radius. Different adjusted rotation speeds corresponding to different supplementary centrifugal forces and reference flame radii are stored in the centrifugal force database, which is a database set by humans and will not be elaborated here. By rotating the gas outlet cover, the area of contact between the flame and the bottom of the cooking utensil is increased, so that the heat transferred by the flame corresponding to the actual output current is consistent with the heat transferred by the flame corresponding to the output current.
