In addition, existing gas grills usually rely on mechanical thermometers installed on the top cover for temperature monitoring, but this method cannot reflect the actual heating of the cooking area (such as the grill surface), resulting in low accuracy in cooking temperature monitoring and control, which can easily lead to unstable quality of the cooked products.

The main control module 101 is also used to detect whether the real-time temperature data meets the preset intelligent control conditions; when the real-time temperature data meets the intelligent control conditions, it outputs a second control signal that matches the real-time temperature data to the fire control module 102. The fire control module 102 is used to perform fire control operation corresponding to the received control drive signal; wherein the control drive signal includes a first control signal and / or a second control signal.

The main control module 101 is also used to poll the fire control interaction results of the interaction module 104 in real time; when the fire control interaction results include fire control commands, it triggers the operation of outputting a first control signal that matches the fire control commands to the fire control module 102.

[0048] Optionally, the oven temperature sensor can be located in the oven cavity area of ​​the grill or in other locations that can monitor the temperature data inside the grill cavity. This embodiment of the invention does not limit this. Further, the oven cavity area can include the rear side of the oven, which is also not limited in this embodiment of the invention.

[0049] Optionally, the grilling area can be the area corresponding to the grilling rack of the grill; further optionally, the oven temperature sensor can be set below the grilling rack, which is not limited in this embodiment of the invention; further optionally, the grilling area can be divided into multiple grilling sub-areas based on pre-set area division conditions; for example, the grilling area can be divided into three grilling sub-areas: left, middle, and right, which is not limited in this embodiment of the invention.

[0050] Optionally, at least one food temperature sensor included in the food temperature sensing unit can be a multi-channel NTC (Negative Temperature Coefficient) and / or a food probe, which is not limited in the embodiments of the present invention.

[0051] In this optional embodiment, the oven temperature sensing unit is optionally used to monitor the real-time temperature of each temperature monitoring zone as real-time temperature field data of the barbecue oven.

[0052] The real-time temperature field data can be composed of furnace temperature sensing data collected by multiple furnace temperature sensors.

[0053] Optionally, a food temperature sensing unit is used to monitor the internal temperature of food being cooked on the grill, serving as real-time food temperature data corresponding to the grill.

[0054] Optionally, the food temperature sensing unit can be inserted into the food (such as meat) through a food temperature sensor to collect the internal temperature of the food as real-time food temperature data. This embodiment of the invention does not limit the scope of the invention.

[0055] As can be seen, the system described in this optional embodiment can accurately monitor the temperature field of each temperature monitoring area in the barbecue oven and accurately monitor the internal temperature of the food on the barbecue oven by setting up oven temperature sensing unit and food temperature sensing unit, thereby improving the accuracy and comprehensiveness of cooking temperature monitoring. This is conducive to improving the accuracy of judgment on whether further intelligent adjustment of firepower is needed in subsequent steps, and thus further improving the accuracy of firepower control of the gas barbecue system.

[0056] In this optional embodiment, the intelligent control conditions may optionally include high-temperature protection conditions and / or balanced cooking conditions.

[0057] Optionally, as an optional implementation, the main control module 101 detects whether the real-time temperature data meets the preset intelligent control conditions; when the real-time temperature data is detected to meet the intelligent control conditions, the specific method of outputting a second control signal matching the real-time temperature data to the fire control module 102 may include: Determine whether any temperature monitoring area in the real-time temperature data has a real-time temperature higher than the preset safe temperature. When it is determined that at least one temperature monitoring area in the real-time temperature data has a real-time temperature higher than the safe temperature, the real-time temperature data is determined to meet the high-temperature protection condition. Based on the real-time temperature data, a first safety control signal corresponding to the high-temperature protection condition is generated, and the first safety control signal is output to the firepower adjustment module 102 as a second control signal. The first safety control signal is used to control the firepower adjustment module 102 to reduce the firepower.

[0058] When the second control signal is the first safety control signal, the control priority corresponding to the second control signal is higher than the control priority corresponding to the first control signal, and the control priority corresponding to the second control signal is the highest priority.

[0059] Optionally, the first safety control signal may include a firepower reduction control signal or a fire shut-off control signal corresponding to a preset protection current value; wherein, the firepower reduction control signal is used to reduce the firepower level to a preset protection value, and the fire shut-off control signal is used to control the firepower adjustment module to shut off the firepower based on a preset multi-level safety protection mechanism. This embodiment of the invention is not limited.

[0060] Optionally, the main control module 101 is also used to acquire the fire parameters of the fire control module 102; determine whether there is a flameout abnormality in the fire control module 102 based on the fire parameters; when it is determined that there is a flameout abnormality in the fire control module 102, determine that the fire control module 102 meets the preset flameout protection conditions, generate a second safety control signal corresponding to the flameout protection conditions, and output the second safety control signal as a second control signal to the fire control module 102.

[0061] When the second control signal is the second safety control signal, the control priority corresponding to the second control signal is higher than the control priority corresponding to the first control signal, and the control priority corresponding to the second control signal is the highest priority.

[0062] Optionally, the second safety control signal is used to control the fire control module to shut down the fire based on a pre-set multi-level safety protection mechanism.

[0063] Optionally, when the control priority corresponding to any control drive signal is the highest priority, the control drive signal can override other priority control drive signals, so that the fire control module immediately executes the fire control operation corresponding to the highest priority control drive signal.

[0064] Optionally, the aforementioned multi-level safety protection mechanism may include various protection control operations. More specifically, when the firepower adjustment module 102 includes a constant current drive control circuit 1021 and an electromagnetic proportional valve module 1022, the protection control operations may include: reducing the drive current value used to drive the electromagnetic proportional valve module 1022 to 0, controlling the solenoid valve to close the main shut-off valve, and cutting off the power supply to the valve body through a relay. This allows the firepower level to be reduced to 0 at the software level, while also closing the gas pipeline, thereby improving the safety and reliability of the gas grilling system's fire-off control.

[0065] As can be seen, the system described in this optional embodiment can also generate a corresponding first safety control signal when the temperature of any temperature monitoring area exceeds the preset safe temperature, so as to reduce the firepower of the barbecue grill, realize the high temperature protection function, reduce the possibility of safety hazards caused by excessive temperature during the grilling process, and thus help improve the safety and reliability of the gas barbecue system.

[0066] Optionally, as another optional implementation, the main control module 101 detects whether the real-time temperature data meets the preset intelligent control conditions; when the real-time temperature data is detected to meet the intelligent control conditions, the specific method of outputting a second control signal matching the real-time temperature data to the fire control module 102 may include: Based on real-time temperature data, determine whether the real-time temperature of all grilling areas is consistent. When it is determined that the real-time temperature of at least one barbecue sub-area is inconsistent with the real-time temperature of the other barbecue sub-areas, it is determined that the real-time temperature data meets the conditions for balanced cooking. Then, the target sub-area whose temperature needs to be adjusted is determined from all the barbecue sub-areas. Based on the target sub-area and the real-time temperature data, a balanced control signal corresponding to the target sub-area is generated, and the balanced control signal is output to the firepower adjustment module 102 as a second control signal. The balanced control signal is used to control the firepower adjustment module 102 to adjust the firepower of the target sub-area.

[0067] Optionally, the number of target sub-regions whose temperature needs to be adjusted can be at least one, and this embodiment of the invention does not limit the number.

[0068] As can be seen, the system described in this optional embodiment can also determine the target sub-region whose temperature needs to be adjusted when the real-time regional temperatures of multiple grilling sub-regions are inconsistent, and generate a corresponding equalization control signal to output the equalization control signal to the firepower adjustment module to adjust the firepower of the target sub-region. This enables intelligent equalization adjustment of the firepower when the temperature of the grilling area is uneven, thereby achieving balanced grilling temperature adjustment. This improves the efficiency and accuracy of heating food, helps reduce the occurrence of food burning due to excessively high temperature or failing to cook properly due to excessively low temperature in some areas, and further improves the cooking quality stability of the gas grilling system.

[0069] In this optional embodiment, optionally, such as Figure 2 As shown, the firepower adjustment module 102 may include a constant current drive control circuit 1021 and an electromagnetic proportional valve module 1022; the constant current drive control circuit 1021 is electrically connected to the main control module 101, and the constant current drive control circuit 1021 is also electrically connected to the electromagnetic proportional valve module 1022.

[0070] The electromagnetic proportional valve module 1022 includes multiple proportional valve groups, each of which is located under one of the barbecue sub-areas. Each proportional valve group includes two proportional valves, and each proportional valve corresponds to one burner.

[0071] Optionally, for each grilling sub-zone, the oven temperature sensor for monitoring that sub-zone is located in the middle of the two burners; this embodiment of the invention does not impose any limitations.

[0072] As can be seen, the system described in this optional embodiment can also control the electromagnetic proportional valve module by setting a constant current drive control circuit, which can drive the electromagnetic proportional valve more precisely, thereby controlling the firepower of the burner more precisely; and can also adjust the firepower of each grilling sub-zone more flexibly and precisely by setting a proportional valve group including two proportional valves for each grilling sub-zone.

[0073] In this optional embodiment, optionally, the main control module 101 determines the target sub-region whose temperature needs to be adjusted from all the grilling sub-regions, and generates the equalization control signal corresponding to the target sub-region based on the target sub-region and real-time temperature data, which may include: For any grilling sub-area, determine whether the real-time area temperature corresponding to the grilling sub-area is lower than the real-time area temperature corresponding to the other grilling sub-areas, and whether the area temperature difference between the grilling sub-area and the other grilling sub-areas is greater than or equal to a preset temperature difference. When it is determined that the real-time temperature of the barbecue sub-area is lower than that of the other barbecue sub-areas, and the temperature difference between the barbecue sub-area and the other barbecue sub-areas is greater than or equal to a preset temperature difference, the area status of the barbecue sub-area is determined to be the "new ingredient" status, and the barbecue sub-area is determined to be the target sub-area; the "new ingredient" status is used to indicate that barbecue ingredients to be cooked have been added to the barbecue sub-area. A first equalization control signal is generated for the target proportional valve group corresponding to the target sub-region; wherein, the first equalization control signal is used to alternately control the opening degree of the two proportional valves in the target proportional valve group.

[0074] Furthermore, the first equalization control signal includes a first sub-signal for the first proportional valve in the target proportional valve group and a second sub-signal for the second proportional valve in the target proportional valve group; wherein, when the driving current value corresponding to any one of the sub-signals in the first equalization control signal is an upward current value, the driving current value corresponding to the other sub-signal in the first equalization control signal remains at a normal current value; wherein, optionally, the normal current value can be a preset driving current value, which is not limited in this embodiment of the invention.

[0075] Further optionally, when the second control drive signal includes the first equalization control signal, after the fire control module 102 executes the fire control operation corresponding to the control drive signal according to the received control drive signal, the main control module 101 can also be used for: For the target sub-region, first temperature change information under the first alternating control state and second temperature change information under the second alternating control state are obtained; wherein, the first alternating control state is the control state when the first sub-signal in the first equalization control signal is used to control the opening of the first proportional valve to increase; the second alternating control state is the control state when the second sub-signal in the second equalization control signal is used to control the opening of the second proportional valve to increase. By comparing the first temperature change information with the second temperature change information, the temperature change comparison results are obtained. When the temperature change comparison result is used to indicate that the temperature rise of the target sub-region under the first alternating control state is more obvious than the temperature rise of the target sub-region under the second alternating control state, the first sub-signal and the second sub-signal in the first equalization control signal are adjusted so that the driving current value corresponding to the second sub-signal, that is, the driving current value corresponding to the second proportional valve, is the upward adjustment current value, and the driving current value corresponding to the first sub-signal, that is, the driving current value corresponding to the first proportional valve, is the normal current value. Similarly, when the temperature change comparison result is used to indicate that the temperature rise of the target sub-region under the second alternating control state is more significant than that under the first alternating control state, the first sub-signal and the second sub-signal in the first equalization control signal are adjusted so that the driving current value corresponding to the first sub-signal, i.e. the driving current value corresponding to the first proportional valve, is the upward current value, and the driving current value corresponding to the second sub-signal, i.e. the driving current value corresponding to the second proportional valve, is the normal current value.

[0076] It can be understood that when the temperature change comparison result indicates that the temperature rise of the target sub-region under the first alternating control state is more significant than that under the second alternating control state, it can be determined that the food placement position within the target sub-region is closer to the second proportional valve. Therefore, by increasing the driving current value corresponding to the second proportional valve, the opening of the second proportional valve can be increased, thereby increasing the firepower of the burner corresponding to the second proportional valve to heat the food more efficiently.

[0077] For example, when the temperature detected by any oven temperature sensor is too low and the temperature of the adjacent area is normal, it is determined that food has been added to the area corresponding to the oven temperature sensor. At this time, the current of the two proportional valves in that area is briefly alternating. For example, if the temperature of the area rises more significantly when the driving current value corresponding to the first proportional valve v1 is increased, it can be determined that the food is closer to the position of the second proportional valve v2. Therefore, the driving current corresponding to the second proportional valve v2 can be increased, while the driving current corresponding to the first proportional valve v1 is readjusted to the normal current. This embodiment of the invention is not limited.

[0078] As can be seen, the system described in this optional embodiment can also determine that food has been added to any grilling area when the temperature of any grilling area is too low compared to other grilling areas. In response, a first equalization control signal is generated to adjust the heat of that area accordingly. This further improves the accuracy and flexibility of the heat control of the gas grilling system, while also increasing the cooking efficiency and flexibility for the added food in that area, thereby further enhancing the intelligence of the gas grilling system.

[0079] In this optional embodiment, alternatively, as another optional implementation, the main control module 101 determines the target sub-region whose temperature needs to be adjusted from all the grilling sub-regions, and generates the equalization control signal corresponding to the target sub-region based on the target sub-region and real-time temperature data, which may include: When the real-time area temperature corresponding to all the barbecue sub-areas is inconsistent, all the barbecue sub-areas are determined as target sub-areas, and the standard temperature to be achieved is determined based on the real-time area temperature corresponding to all the barbecue sub-areas. For each target sub-region, a second equalization control signal is generated for the proportional valve group corresponding to the target sub-region based on the standard temperature and the real-time regional temperature. The second equalization control signal is used to simultaneously control the opening degree of the two proportional valves in the proportional valve group.

[0080] For example, suppose the grilling area includes three grilling sub-areas. When the temperature of the three grilling sub-areas deviates, the current of the two proportional valves under that area is adjusted simultaneously on a per-area basis. This embodiment of the invention is not limited to this.

[0081] As can be seen, the system described in this optional embodiment can also generate a corresponding second equalization control signal for the temperature of each grilling sub-zone when there is a temperature deviation in all grilling sub-zones. This allows for targeted adjustment of the heat in that grilling sub-zone, thereby further improving the accuracy and flexibility of the heat control of the gas grilling system while reducing the heating deviation between grilling sub-zones. This results in more even cooking of the food and further enhances the intelligence of the gas grilling system.

[0082] In this optional embodiment, the constant current drive control circuit 1021 is configured to adjust the required output drive current according to the received control drive signal and output the drive current to the electromagnetic proportional valve module 1022, so as to adjust the opening degree of the target proportional valve in the electromagnetic proportional valve module 1022 based on the drive current, thereby controlling the combustion firepower of the burner corresponding to the electromagnetic proportional valve module 1022. The target proportional valve includes at least one proportional valve in at least one proportional valve group.

[0083] Optionally, the constant current drive control circuit 1021 can adjust the output drive current by setting a comparator and combining the received control drive signal and the real-time voltage fed back by the sampling resistor. This embodiment of the invention does not limit the scope of the invention.

[0084] Further optional information can be found in [link to relevant documentation]. Figure 3 , Figure 3 This is a schematic diagram of a constant current drive control circuit disclosed in an embodiment of the present invention; as shown below. Figure 3 As shown, A high-precision sampling resistor group (including such as...) is connected in series at the output terminal (P-VBN) of the proportional valve drive circuit in the constant current drive control circuit. Figure 3 The first resistor R98 and the second resistor R99 shown convert the actual current flowing through the proportional valve coil into a feedback voltage in real time, and input it to the inverting input of the comparator U5B via the third resistor R50. This structure, together with the DO-VB reference signal (i.e. the drive control signal mentioned above) output by the MCU (i.e. the main control module 101 mentioned above), forms a hardware-level closed-loop constant current control, which eliminates the influence of the solenoid valve coil resistance drift with temperature on the firepower accuracy; and, through closed-loop constant current control, it can automatically compensate for the resistance change of the proportional valve caused by coil heating or other reasons, ensuring the accuracy and stability of the firepower output.

[0085] As can be seen, the system described in this optional embodiment can also adjust the required output drive current according to the received control drive signal through a constant current drive control circuit, and output drive current to the electromagnetic proportional valve module. Based on the drive current, the opening degree of the target proportional valve in the electromagnetic proportional valve module is adjusted, thereby controlling the combustion firepower of the burner corresponding to the electromagnetic proportional valve module. The opening degree of the proportional valve can be adjusted more reliably through the constant current drive control circuit, thereby adjusting the combustion degree of the burner more accurately and reliably, further improving the accuracy and reliability of the firepower control of the gas combustion system.

[0086] In yet another alternative embodiment, such as Figure 2 As shown, the multi-source heterogeneous sensing module 103 may further include a weight sensing module 1032; and the system may further include a communication module 105, which is electrically connected to the main control module 101 and also communicatively connected to the user terminal; wherein: The multi-source heterogeneous sensing module 103 is also used to monitor the real-time weight data of the gas canister corresponding to the barbecue grill based on the weight sensing module 1032, and to feed back the real-time weight data to the main control module 101. The main control module 101 is also used to determine the remaining amount of gas in the gas tank based on real-time weight data and a pre-set flow model. The main control module 101 is also used to transmit real-time data to the display module and display the real-time data through the display module; or, through the communication module 105, to send the real-time data corresponding to the intelligent gas barbecue system to the user terminal; wherein, the real-time data includes the remaining gas and / or real-time temperature data.

[0087] Optionally, the weight sensing module 1032 may include a weight sensor, but this embodiment of the invention does not limit the scope of the invention.

[0088] Optionally, the communication module 105 may include a communication module with one or more wireless communication methods, such as a Wi-Fi module and / or a Bluetooth module. This embodiment of the invention does not limit the scope of the invention.

[0089] Optionally, the display module can be the display in the interactive module 104, or other display devices associated with the barbecue grill. This embodiment of the invention does not limit the scope of the display module.

[0090] Optionally, after receiving the real-time weight data, the main control module 101 can use a Kalman filter algorithm to remove instantaneous jump values ​​in the real-time weight data to obtain processed real-time weight data. In subsequent steps, the remaining amount of gas in the gas tank can be determined based on the processed real-time weight data and a pre-set flow model. This embodiment of the invention does not impose any limitations.

[0091] Optionally, the main control module 101 is further configured to generate a gas remaining quantity prompt message corresponding to the preset gas remaining quantity when the gas remaining quantity is less than or equal to the preset gas remaining quantity, and send the gas remaining quantity prompt message to the user terminal through the communication module 105; wherein the gas remaining quantity prompt message is used to remind the user that the gas remaining quantity in the gas tank is insufficient, and this embodiment of the present invention does not limit it.

[0092] As can be seen, the system described in this optional embodiment can monitor the weight data of the gas cylinder through the weight sensing module, and then calculate the remaining gas in the gas cylinder through the main control module combined with the flow model. Then, through the display module or communication module, it can provide the user with real-time data including the remaining gas and / or temperature data, realizing dynamic gas remaining prediction and monitoring. This can improve the accuracy of determining the remaining gas while increasing the convenience for users to understand the usage of the barbecue system, which is conducive to users accurately planning cooking time.

[0093] In this optional embodiment, the main control module 101 may determine the specific method by which it determines the remaining gas volume in the gas tank based on real-time weight data and a pre-set flow model, which may include: Determine the current status of the intelligent gas barbecue system; If the current state is static, the first gas quantity corresponding to the real-time weight data is determined as the remaining gas quantity in the gas tank. If the current state is working, the current data corresponding to the firepower adjustment module 102 is obtained, and the estimated gas consumption of the intelligent gas barbecue system is determined according to the pre-set flow model and current data. Determine the initial weight data of the gas canister before the intelligent gas barbecue system enters the working state, and determine the initial gas volume corresponding to the initial weight data; wherein, the initial weight data is the real-time weight data at one point in time; Based on the estimated gas consumption and the initial gas quantity, the second gas quantity corresponding to the current moment is determined as the remaining gas quantity in the gas tank.

[0094] When the intelligent gas grilling system is in a static state, it indicates that the system is not currently burning, so there is no gas flowing in the gas tank; when the intelligent gas grilling system is in a working state, it indicates that the system is burning, so there is gas flowing in the gas tank.

[0095] The current data includes the drive current corresponding to each proportional valve, which is recorded in real time.

[0096] Optionally, the flow model can be a current-flow curve, and further, it can be expressed by the following formula:

[0097] Where I is the driving current of the proportional valve and Q is the gas flow rate per unit time; the estimated gas consumption can be obtained from the calculated gas flow rate.

[0098] As can be seen, the system described in this optional embodiment can also determine the first gas quantity corresponding to the real-time weight data as the gas remaining quantity in the gas tank when the intelligent gas grilling system is in a static state; when the intelligent gas grilling system is in a working state, it determines the estimated gas consumption corresponding to the intelligent gas grilling system based on the pre-set flow model and the current data corresponding to the firepower adjustment module, and determines the initial gas quantity corresponding to the initial weight data of the gas tank before the intelligent gas grilling system enters the working state. Then, combining the estimated gas consumption and the initial gas quantity, it determines the second gas quantity corresponding to the current moment as the gas remaining quantity in the gas tank. This allows for the selection of a more accurate method to calculate the gas remaining quantity when the intelligent gas grilling system is in different states, thereby improving the flexibility and accuracy of determining the gas remaining quantity in the gas tank, and thus helping users to plan their gas usage more accurately during cooking.

[0099] In this optional embodiment, the main control module 101 is optionally also used to verify the gas balance and obtain a verification result; when the verification result indicates that the difference between the gas balance and the actual gas balance is greater than the preset balance difference, the flow model is corrected according to the actual gas balance.

[0100] The actual gas balance can be the actual measured gas balance, or it can be the gas balance determined by real-time weight data obtained from the weight sensing module after filtering outliers. This embodiment of the invention does not limit the specific gas balance.

[0101] As can be seen, the system described in this optional embodiment can also verify the determined gas balance through the main control module. If the difference between the gas balance and the actual gas balance is greater than the preset balance difference, the flow model is corrected according to the actual gas balance to realize intelligent closed-loop model correction, which is conducive to improving the accuracy of model correction, thereby improving the accuracy of subsequent gas balance determination.

[0102] In this optional embodiment, the main control module 101 may also be used to receive relevant control commands from the user through the communication module 105, and to perform matching function control operations based on the received relevant control commands.

[0103] For example, the relevant control commands may include one or more of the following: fire off control command, timer setting command, energy consumption statistics command, and usage time statistics command. Correspondingly, the function control operations may include one or more of the following: fire off control operation, timer setting operation, energy consumption statistics operation, and usage time statistics operation. This embodiment of the invention does not limit the scope of the control commands.

[0104] As can be seen, the system described in this optional embodiment can also receive relevant control commands from the user through the communication module, so as to execute corresponding functional control operations through the main control module, thereby improving the user's control flexibility and convenience of the intelligent gas barbecue system.

[0105] In another optional embodiment, the main control module 101 is further configured to generate a constant temperature control signal based on real-time temperature data and a preset target constant temperature value, and output the constant temperature control signal as a third control signal to the firepower adjustment module when a constant temperature control command is detected. Among them, the control priority corresponding to the third control signal is higher than the control priority corresponding to the first control signal; The control driving signal includes at least one of a first control signal, a second control signal, and a third control signal.

[0106] The main control module 101 can be configured with a constant temperature control mode, and the constant temperature control command can be used to trigger the activation of the constant temperature control mode.

[0107] Optionally, the isothermal algorithm may include a PID (Proportional-Integral-Derivative) algorithm or an ADRC (Active Disturbance Rejection Control) algorithm, and the embodiments of the present invention are not limited thereto.

[0108] As can be seen, the system described in this optional embodiment can generate and output a constant temperature control signal through the main control module, based on a constant temperature algorithm and combined with real-time temperature data and target constant temperature value. This can further improve the accuracy of fire control of the gas grilling system, while also improving the accuracy of cooking temperature control, achieving constant temperature cooking, and thus helping to improve the stability of cooking quality of the gas grilling system.

[0109] In an embodiment of the present invention, for example, the intelligent gas grilling system integrating multi-dimensional sensing and digital adjustment may include the following four main components: (1) Interaction and digital hub: It consists of a microprocessor (MCU, i.e. the main control module mentioned above), a touch display (i.e. the interaction module mentioned above), and a wireless communication module (Wi-Fi / Bluetooth) (i.e. the communication module mentioned above); among them, the touch display can be embedded in the front of the barbecue grill as a window for human-computer interaction, and the MCU is installed on the inside of the panel and connected to the display, touch screen, wireless module and other sensors through the bus; (2) Digital firepower execution module: It consists of multiple electromagnetic proportional valves (i.e., the electromagnetic proportional valve module mentioned above) and constant current drive control circuit. Each burner corresponds to one electromagnetic proportional valve. The MCU adjusts the output mA-level current of the constant current drive circuit through the PWM signal (i.e., the control drive signal mentioned above) according to the digital firepower command (gear / firepower value) input by the touch screen, and accurately drives the opening degree of the proportional valve core. (3) Multi-source heterogeneous sensing array: Multiple k-type thermocouples (i.e., the oven temperature sensing unit mentioned above) are distributed in various areas such as under the grill and behind the flip cover to monitor the real-time temperature field; Multiple NTC and food probes (i.e., the food temperature sensing unit mentioned above) are used to obtain the internal temperature of meat and provide feedback on the doneness; A high-precision weighing sensor (i.e., the weight sensing module mentioned above) is installed at the bottom of the gas cylinder support bracket. (4) IoT Collaboration Layer: The mobile phone can communicate bidirectionally with the MCU of the product through the cloud server in real time. The mobile phone can display the real-time gas balance and temperature of each sensor, and can operate the product to turn off the flame, set the timer, and calculate energy consumption and usage time.

[0110] Example 2 Please see Figure 4, Figure 4 This is a flowchart illustrating an intelligent gas grilling method integrating multi-dimensional sensing and digital adjustment, as disclosed in an embodiment of the present invention. Figure 4 The described intelligent gas grilling method integrating multi-dimensional sensing and digital adjustment can be applied to scenarios requiring heat adjustment of grilling equipment; however, this invention does not limit its application. Figure 4 As shown, this intelligent gas grilling method integrating multi-dimensional sensing and digital adjustment can include the following operations: 201. After detecting the firepower adjustment command triggered by the user, the main control module outputs a first control signal that matches the firepower adjustment command to the firepower adjustment module.

[0111] 202. The temperature sensing module of the multi-source heterogeneous sensing module monitors real-time temperature data and feeds the real-time temperature data back to the main control module.

[0112] In this embodiment of the invention, the real-time temperature data includes the real-time temperature field data of the barbecue oven and / or the real-time food temperature data corresponding to the barbecue oven.

[0113] In this embodiment of the invention, the fire control module and the multi-source heterogeneous sensing module are electrically connected to the main control module, respectively.

[0114] 203. The main control module detects whether the real-time temperature data meets the preset intelligent control conditions.

[0115] 204. When the real-time temperature data is detected to meet the intelligent control conditions, the main control module outputs a second control signal that matches the real-time temperature data to the firepower adjustment module.

[0116] 205. The firepower adjustment module executes the firepower adjustment operation corresponding to the received control drive signal.

[0117] In this embodiment of the invention, the control driving signal includes a first control signal and / or a second control signal.

[0118] As can be seen, the method described in the embodiments of the present invention can, after detecting a user-triggered power adjustment command, output a first control signal matching the power adjustment command to the power adjustment module through the main control module; monitor real-time temperature data through a multi-source heterogeneous sensing module; the real-time temperature data includes real-time temperature field data and / or real-time food temperature data; detect whether the real-time temperature data meets the intelligent control conditions through the main control module; if the detection result is yes, output a second control signal matching the real-time temperature data to the power adjustment module; and execute the power adjustment operation according to the control drive signal through the power adjustment module. In this way, based on the actual triggered digital command and the actual grilling temperature data, the power of the grill can be precisely driven and controlled, thereby realizing intelligent control of the gas grilling system. This improves the accuracy of cooking temperature monitoring and the accuracy of power control of the gas grilling system, which in turn helps to improve the stability of the cooking quality of the gas grilling system.

[0119] In an optional embodiment, the output of a first control signal matching the fire control command from the main control module to the fire control module may include the following operations: Obtain a pre-set fire control mapping table; the fire control mapping table records the mapping relationship between the command values ​​corresponding to various adjustment commands and the drive current reference value; According to the fire control command, find the target current reference value corresponding to the fire control command from the fire control mapping table; Based on the target current reference value, a first control signal corresponding to the target current reference value is generated and output to the fire control module.

[0120] As can be seen, this optional embodiment can find the target current reference value corresponding to the firepower adjustment command from the preset firepower control mapping relationship table, so as to generate and output the corresponding first control signal. It can determine the first control signal corresponding to the firepower adjustment command more efficiently through the preset data mapping relationship, thereby improving the efficiency and accuracy of driving the firepower adjustment module to adjust the firepower, and further improving the firepower control accuracy of the gas barbecue system.

[0121] In an optional embodiment, the temperature sensing module includes an oven temperature sensing unit and a food temperature sensing unit. The oven temperature sensing unit includes multiple oven temperature sensors, each of which is set in one of the temperature monitoring areas of the barbecue oven. All temperature monitoring areas include the oven cavity area corresponding to the barbecue oven and / or the barbecue area corresponding to the barbecue oven. The barbecue area includes at least one barbecue sub-area. In addition, the food temperature sensing unit includes at least one food temperature sensor; The temperature sensing module, which consists of a multi-source heterogeneous sensing module, monitors real-time temperature data and may include the following operations: The oven temperature sensing unit monitors the real-time temperature of each temperature monitoring zone, which serves as the real-time temperature field data of the barbecue oven. The food temperature sensing unit monitors the internal temperature of the food being cooked on the grill, providing real-time food temperature data corresponding to the grill.

[0122] As can be seen, this optional embodiment can accurately monitor the temperature field of each temperature monitoring area in the barbecue oven and accurately monitor the internal temperature of the food on the barbecue oven by setting up an oven temperature sensing unit and a food temperature sensing unit. This improves the accuracy and comprehensiveness of the monitoring of cooking temperature, thereby improving the accuracy of the judgment on whether further intelligent adjustment of the firepower is needed in subsequent steps, and further improving the accuracy of the firepower control of the gas barbecue system.

[0123] In this optional embodiment, the intelligent control conditions may include high-temperature protection conditions and / or balanced cooking conditions. The main control module detects whether the real-time temperature data meets the preset intelligent control conditions. When the real-time temperature data meets the intelligent control conditions, it outputs a second control signal that matches the real-time temperature data to the fire control module. This can include the following operations: Determine whether any temperature monitoring area in the real-time temperature data has a real-time temperature higher than the preset safe temperature. When it is determined that at least one temperature monitoring area in the real-time temperature data has a real-time temperature higher than the safe temperature, the real-time temperature data is determined to meet the high-temperature protection condition. Based on the real-time temperature data, a first safety control signal corresponding to the high-temperature protection condition is generated, and the first safety control signal is output to the firepower adjustment module as a second control signal. The first safety control signal is used to control the firepower adjustment module to reduce the firepower. And / or, Based on real-time temperature data, determine whether the real-time temperature of all grilling areas is consistent. When it is determined that the real-time temperature of at least one grilling sub-zone is inconsistent with the real-time temperature of the other grilling sub-zones, it is determined that the real-time temperature data meets the conditions for balanced cooking. Then, the target sub-zone that needs to be adjusted in temperature is identified from all grilling sub-zones. Based on the target sub-zone and the real-time temperature data, a balanced control signal corresponding to the target sub-zone is generated, and the balanced control signal is output to the firepower adjustment module as a second control signal. The balanced control signal is used to control the firepower adjustment module to adjust the firepower of the target sub-zone. When the second control signal is the first safety control signal, the control priority corresponding to the second control signal is higher than the control priority corresponding to the first control signal, and the control priority corresponding to the second control signal is the highest priority.

[0124] As can be seen, this optional embodiment can also generate a corresponding first safety control signal when the temperature of any temperature monitoring area exceeds the preset safe temperature, so as to reduce the firepower of the barbecue oven, realize the high temperature protection function, reduce the possibility of safety hazards caused by excessive temperature during the barbecue process, and thus improve the safety and reliability of the gas barbecue system. In addition, when it is determined that the real-time temperature of multiple barbecue sub-areas is inconsistent, the target sub-area that needs temperature adjustment can be identified, and a corresponding equalization control signal can be generated. The equalization control signal is output to the firepower adjustment module to adjust the firepower of the target sub-area. In the case of uneven temperature in the barbecue area, the firepower can be intelligently and evenly adjusted, thereby achieving balanced adjustment of the barbecue temperature. This can improve the efficiency and accuracy of heating food, and help reduce the situation where food in some areas is burnt due to excessive temperature or fails to cook due to insufficient temperature, thus further improving the cooking quality stability of the gas barbecue system.

Based on the drive current, the opening degree of the target proportional valve in the electromagnetic proportional valve module is adjusted, thereby controlling the combustion firepower of the burner corresponding to the electromagnetic proportional valve module. The target proportional valve includes at least one proportional valve in at least one proportional valve group.

[0126] As can be seen, this optional embodiment can also control the electromagnetic proportional valve module by setting a constant current drive control circuit, which can drive the electromagnetic proportional valve more precisely, thereby controlling the firepower of the burner more precisely; and it can also adjust the firepower of each grilling sub-area more flexibly and precisely by setting a proportional valve group including two proportional valves for each grilling sub-area; and by using a constant current drive control circuit to adjust the required output drive current according to the received control drive signal and output the drive current to the electromagnetic proportional valve module, so as to adjust the opening of the target proportional valve in the electromagnetic proportional valve module based on the drive current, thereby controlling the combustion firepower of the burner corresponding to the electromagnetic proportional valve module.

If the current state is working, the current data corresponding to the firepower adjustment module is obtained, and the estimated gas consumption of the intelligent gas barbecue system is determined according to the pre-set flow model and current data. Determine the initial weight data of the gas canister before the intelligent gas barbecue system enters the working state, and determine the initial gas volume corresponding to the initial weight data; wherein, the initial weight data is the real-time weight data at one point in time; Based on the estimated gas consumption and the initial gas quantity, the second gas quantity corresponding to the current moment is determined as the remaining gas quantity in the gas tank.

[0130] As can be seen, this optional embodiment can also determine the first gas quantity corresponding to the real-time weight data as the gas remaining quantity in the gas tank when the intelligent gas grilling system is in a static state; when the intelligent gas grilling system is in a working state, it determines the estimated gas consumption corresponding to the intelligent gas grilling system based on the pre-set flow model and the current data corresponding to the firepower adjustment module, and determines the initial gas quantity corresponding to the initial weight data of the gas tank before the intelligent gas grilling system enters the working state. Then, combining the estimated gas consumption and the initial gas quantity, it determines the second gas quantity corresponding to the current moment as the gas remaining quantity in the gas tank. This allows for the selection of a more accurate method to calculate the gas remaining quantity when the intelligent gas grilling system is in different states, thereby improving the flexibility and accuracy of determining the gas remaining quantity in the gas tank, and thus helping users to plan their gas usage more accurately during cooking.

[0131] In an optional embodiment, the method may further include the following operations: When a constant temperature control command is detected, the main control module generates a constant temperature control signal based on real-time temperature data and a pre-set target constant temperature value, according to a pre-set constant temperature algorithm, and outputs the constant temperature control signal as a third control signal to the firepower adjustment module. Among them, the control priority corresponding to the third control signal is higher than the control priority corresponding to the first control signal; The control driving signal includes at least one of a first control signal, a second control signal, and a third control signal.

[0132] As can be seen, this optional embodiment can generate and output a constant temperature control signal through the main control module, based on the constant temperature algorithm and combined with real-time temperature data and target constant temperature value.
