[0024] Embodiment 1

[0025] Figure 1a A schematic diagram of the structure of an integrated stove is provided for the first embodiment of the present invention. Figure 1aAs shown, the integrated stove includes a first image acquisition unit 101, a second image acquisition unit 102, a third image acquisition unit 103, a firepower adjustment module 104, a pan sliding detection module 105, a tilt detection module 106 and an image processing module 107.

It should be noted that the integrated stove is provided with an electric flame stove, and the stove in the stove frame of the electric flame stove is provided with at least two stove heating areas, which can realize the zone heating function, and the firepower adjustment module 104 can asynchronously or synchronously control the at least two stove heating areas to perform asynchronous heating or synchronous heating.

[0026] The first image acquisition unit 101 can be set in the head area of ​​the integrated stove to acquire images of the pot on the stove rack; the second image acquisition unit 102 can be set on the left side of the stove rack to acquire images of the left side of the pot on the stove rack; the third image acquisition unit 103 can be set on the back side of the stove rack to acquire images of the back side of the pot on the stove rack; the image processing module 107 can segment the image and identify the edge of the stove rack and the edge of the pot in the image; the pan sliding detection module 105 can be used to determine whether the pot on the stove rack is sliding; the tilt detection module 106 can be used to determine whether the pot on the stove rack is tilted. Optionally, the setting positions of the firepower adjustment module 104, the pan sliding detection module 105, the tilt detection module 106 and the image processing module 107 can be adaptively set according to those skilled in the art, for example, they can be set on the head of the integrated stove.

[0027] Optionally, in the embodiment of the present invention, those skilled in the art may adaptively set the type of the integrated stove, which is not specifically limited herein. For example, the integrated stove may be set as an electric flame integrated stove, and the firepower of the electric flame stove may be controlled by controlling the electric power of the electric flame stove.

[0028] Figure 1b A flowchart of a method for adjusting firepower is provided for the first embodiment of the present invention. This embodiment is applicable to the case where the pot slips or tilts during cooking. The method can be executed by a firepower adjustment system. The firepower adjustment system can be implemented in the form of hardware and / or software. The firepower adjustment system can be configured in an integrated stove, such as an electric flame integrated stove. Figure 1b As shown, the method includes:

[0029] S110: Use a first image acquisition unit, a second image acquisition unit, and a third image acquisition unit to respectively acquire images of a stove rack of the integrated stove to obtain a first stove rack image, a second stove rack image, and a third stove rack image.

[0030] The first grate image can be used to determine whether the pot slides; the second grate image can be used to determine whether the pot tilts in the front-to-back direction; and the third grate image can be used to determine whether the pot tilts in the left-to-right direction. It should be noted that the first grate image, the second grate image, and the third grate image can all refer to images of the pot on the grate.

[0031] In the embodiment of the present invention, when the integrated stove is in working state, the first image acquisition unit, the second image acquisition unit and the third image acquisition unit provided in the head area of ​​the integrated stove can respectively acquire images of the oven rack area at a preset acquisition frequency, and respectively acquire the first oven rack image, the second oven rack image and the third oven rack image. Optionally, the preset acquisition frequency can be adaptively set according to those skilled in the art.

[0032] Optionally, the activation of the first image acquisition unit, the second image acquisition unit and the third image acquisition unit can be controlled according to the working state of the integrated stove. When the integrated stove is in working state, the first image acquisition unit, the second image acquisition unit and the third image acquisition unit can be automatically activated. Alternatively, temperature sensors can be provided in the first image acquisition unit, the second image acquisition unit and the third image acquisition unit to monitor the temperature of the stove rack area. When the temperature monitored by any temperature sensor exceeds a certain threshold, it is determined to activate the first image acquisition unit, the second image acquisition unit and the third image acquisition unit for image acquisition. When the integrated stove is in non-working state, the image acquisition unit can be in a dormant state.

[0033] S120: Using a pan sliding detection module to perform pan sliding detection based on the first grate image to determine a pan sliding direction.

[0034] The pan sliding direction can be used to characterize the sliding direction of the pan on the stove rack.

[0035] In an embodiment of the present invention, when a pot is being cooked on a stove rack, the pot may slip, that is, the position of the pot on the stove rack moves, causing uneven heating of the pot, resulting in dry burning of the pot or spillage of the cooked food in the pot. A pot slip detection module can be used to perform pot slip detection on the pot based on the first stove rack image captured by the first image capture unit, identify the position of the pot and the stove rack in the first stove rack image, determine whether the pot slips, and then determine the direction of the pot slip.

[0036] S130: Using a tilt detection module to perform pot tilt detection based on the second grate image and the third grate image to determine a tilt direction of the pot.

[0037] In the embodiment of the present invention, when the pot is being cooked on the stove rack, the pot may also tilt, that is, the bottom of the pot is not completely in contact with the stove rack, and the pot is not in a horizontal position, so that the pot is heated unevenly and causes the pot to dry burn or the cooked food in the pot to spill. The tilt detection module can be used to detect the tilt of the pot based on the second stove rack image and the third stove rack image captured by the second image acquisition unit and the third image acquisition unit, and identify the edge position of the pot in the second stove rack image and the third stove rack image to determine whether the pot is tilted, and then determine the tilt direction of the pot.

[0038] S140, using a firepower adjustment module to adjust the cooking firepower of the integrated stove based on the pan sliding direction and the tilting direction.

[0039] Specifically, when it is determined that the pot is sliding or tilting, the firepower adjustment module can be used to adjust the firepower of the grate area of ​​the integrated stove based on the sliding direction or tilting direction of the pot. It should be noted that at least two stove heating areas are set in the stove in the grate of the integrated stove (the internal space area of ​​the grate), and the firepower adjustment module can perform asynchronous or synchronous control on the at least two stove heating areas. It should be noted that the pot may only slide on the grate, or only tilt, and sliding and tilting may occur at the same time. In the embodiment of the present invention, the cooking firepower of the integrated stove can be adjusted according to the sliding direction and / or tilting direction of the pot on the grate.

[0040] Optionally, a firepower adjustment module is used to adjust the cooking firepower of the integrated stove based on the sliding direction and the tilting direction of the pot, including: using the firepower adjustment module to increase the firepower of the stove heating area corresponding to the sliding direction of the pot with a first preset adjustment ratio, and to reduce the firepower of the stove heating area corresponding to the opposite direction of the sliding direction of the pot with the first preset adjustment ratio; using the firepower adjustment module to increase the firepower of the stove heating area corresponding to the tilting direction with a second preset adjustment ratio, and to reduce the firepower of the stove heating area corresponding to the opposite direction of the tilting direction with a second preset adjustment ratio.

[0041] Among them, the first preset adjustment ratio can be determined according to the sliding distance of the cookware in the sliding direction; the second preset adjustment ratio can be determined according to the tilt angle; it should be noted that the longer the sliding distance, the larger the first preset adjustment ratio, and the larger the tilt angle, the larger the second preset adjustment ratio.

[0042] For example, if the pot slides to the right, that is, the pot slides to the right on the stove rack, at this time, compared with the position of the pot before sliding, the heating area of ​​the pot on the right side of the stove that needs to be heated increases, and the heating area of ​​the pot on the left side of the stove that needs to be heated decreases. If the stove heating area in the stove still heats the pot at the same firepower as before the pot slides, the right bottom of the pot is very likely to burn. The heating power of the stove heating area on the right side of the stove can be increased by the firepower adjustment module to increase the firepower of the heating area on the right, and at the same time reduce the heating power of the stove heating area on the left side of the stove to reduce the firepower of the heating area on the left. If the pot tilts to the right and forward, the cooking firepower of the heating area on the right side and the front side of the stove needs to be increased, and the cooking firepower of the heating area on the left side and the back side of the stove needs to be reduced compared to the state before the pot tilts. If the heating area in the stove still heats the pot with the firepower before the pot tilts, the left bottom and the front bottom of the pot are very likely to burn. The heating power of the heating area on the right side and the front side of the stove can be increased through the firepower adjustment module to increase the firepower of the heating area on the right side and the front side, while reducing the heating power of the heating area on the left side and the back side of the stove to reduce the firepower of the heating area on the left side and the back side. It should be noted that the number of stove heating areas corresponding to the sliding direction of the pot is at least one, and the number of stove heating areas corresponding to the tilting direction of the pot is also at least one.

[0043] By dynamically adjusting the firepower of different heating areas in the stove, the smooth progress of the cooking process can be ensured and the safety of the cooking process can be improved.

[0044] Optionally, a firepower adjustment module is used to adjust the cooking firepower of the integrated stove based on the sliding direction and the tilting direction of the pot, and also includes: if the sliding distance of the pot on the stove rack of the integrated stove in the sliding direction of the pot is greater than a preset distance threshold, the firepower adjustment module is used to turn off the firepower of the stove heating area corresponding to the opposite direction of the sliding direction of the pot.

[0045] For example, if the sliding distance of the pot on the stove rack of the integrated stove sliding to the right is greater than the preset distance threshold, it means that the stove heating area on the left side of the stove is basically unable to heat the pot at the position of the pot on the stove rack after the pot slides. In other words, the position of the pot on the stove rack after the pot slides is too far away from the stove heating area on the left side of the stove. At this time, in order to prevent the stove heating area on the left side of the stove from continuing to heat ineffectively and to avoid dry burning of the stove heating area on the left side of the stove, the firepower adjustment module can be used to turn off the heating power of the stove heating area on the left side of the stove to turn off the firepower of the stove heating area on the left side. Optionally, the preset distance threshold can be adaptively set according to those skilled in the art.

[0046] Optionally, a firepower adjustment module is used to adjust the cooking firepower of the integrated stove based on the sliding direction and the tilting direction of the pot, and also includes: if the inclination angle of the pot on the stove rack of the integrated stove in the tilting direction is greater than a preset angle threshold, the firepower adjustment module is used to turn off the firepower of all stove heating areas of the integrated stove.

[0047] For example, if the tilt angle of the pot on the stove rack of the integrated stove in the tilt direction is greater than the preset angle threshold, indicating that the pot is about to tip over, the heating power input of all stove heating areas in the stove can be cut off through the firepower adjustment module to turn off the cooking firepower of the integrated stove to avoid dry burning, etc. Optionally, the preset angle threshold can be adaptively set according to those skilled in the art.

[0048] The technical solution of the embodiment of the present invention collects images of the grate area, and performs pot sliding detection based on the collected images of the grate area to determine the pot sliding direction and tilting direction, and adjusts the firepower of the stove grate area of ​​the integrated stove according to the pot sliding direction and tilting direction of the pot, thereby avoiding the burning or drying of the pot caused by the pot sliding or tilting, improving the safety of the cooking process, and at the same time improving the intelligence level of the integrated stove, further ensuring the safety of the cooking process when there is no one to supervise the cooking process.

[0049] Embodiment 2

[0050] Figure 2a This is a flowchart of a firepower adjustment method provided in the second embodiment of the present invention. This embodiment provides specific steps for the image processing module to process the image based on the above embodiment. It should be noted that for the part not described in detail in the embodiment of the present invention, please refer to the relevant description of other embodiments, which will not be repeated here. Figure 2a As shown, the method includes

[0051] S210: Use an image processing module to divide the first grate image into regions, divide the first grate region image into at least two image segmentation regions, and determine the gap area between the pot and the edge of the grate in each image segmentation region.

[0052] S220: Using an image processing module to process a first grate image acquired for the first time by the first image acquisition unit, the gap area between the pot and the edge of the grate in each image segmentation area of ​​the first grate image is used as the initial area corresponding to the image segmentation area.

[0053] S230: Using an image processing module to process the second oven rack image and the third oven rack image using the horizontal placement surface of the oven rack as a standard reference line, and determining the tilt angles of the cookware in the front-to-back direction and the left-to-right direction.

[0054] The gap area can be used to characterize the distance between the pot and the edge of the stove rack; the first stove rack image acquired for the first time can refer to the first image acquired by the first image acquisition unit after startup. It should be noted that the horizontal placement surface of the stove rack can refer to the landing surface of the pot on the stove rack. Since the stove rack is fixed to the integrated stove, the stove rack is not easy to move or tilt. Using the horizontal placement surface of the stove rack as the reference line can effectively detect whether the pot is tilted.

[0055] Optionally, the image processing module may divide the first grate image into at least two image segmentation areas based on the center point of the grate in the first grate image, such as Figure 2b As shown, the first furnace image is equally divided into four image segmentation regions: a first fan-shaped region, a second fan-shaped region, a third fan-shaped region, and a fourth fan-shaped region. Figure 2b The black circular area shown in is the area formed by the edge of the pot and the edge of the stove rack, that is, the area of ​​the stove rack not occupied by the pot. There is a part of the black circular area in each sector area, which is used to indicate the distance between the edge of the pot and the edge of the stove rack in each sector area. Optionally, in the embodiment of the present invention, the first sector area, the second sector area, the third sector area and the fourth sector area can correspond to four stove heating areas set in the stove respectively.

[0056] Optionally, image processing is performed on the second grate image and the third grate image, including: taking a horizontal line indicated by the horizontal placement surface of the grate as a standard reference line, performing horizontal detection on the edge of the pot indicated in the second grate image and the third grate image, and when there is an intersection between the standard reference line and the edge of the pot indicated in the second grate image or the third grate image, using a first angle or a second angle formed by the standard reference line and the edge of the pot as the inclination angle of the pot.

[0057] The first angle may be used to indicate the tilt angle of the cookware in the front-to-back direction; the second angle may be used to indicate the tilt angle of the cookware in the left-to-right direction.

[0058] Optionally, in another optional implementation of the embodiments of the present invention, a pan sliding detection module is used to perform pan sliding detection based on the first grate image to determine the direction of the pan sliding, including: using the pan sliding detection module, respectively comparing the gap area between the pot and the edge of the grate corresponding to at least two image segmentation areas divided by the first grate image with the initial area corresponding to each image segmentation area; if the gap area corresponding to the image segmentation area is reduced by a preset area compared with the corresponding initial area, then determining the direction of the image segmentation area is the direction of the pan sliding.

[0059] Specifically, if before and after the pot slides, there is a gap area corresponding to a certain image segmentation area that is smaller than the preset area compared to its corresponding initial area, then it is determined that the pot has slid toward the image segmentation area, and the direction of the image segmentation area is the moving direction of the pot. It should be noted that in the embodiment of the present invention, the sliding distance of the pot in each image segmentation area can be determined by the difference in the gap area before and after the pot slides. The larger the difference in the gap area, the larger the sliding distance of the pot in the current image segmentation area, and the pot can slide toward at least one image segmentation area at the same time, that is, the direction in which the pot slides during the cooking process is random, and it does not slide in only one direction.

[0060] Optionally, in another optional implementation of the embodiments of the present invention, a tilt detection module is used to perform pot tilt detection based on the second grate image and the third grate image, including: using the tilt detection module, the tilt angles of the pot in the front-to-back direction and the left-to-right direction respectively indicated by the second grate image and the third grate image are compared with a preset tilt angle threshold; if the tilt angle of the pot is greater than the tilt angle threshold, the side of the pot edge that is lower than the standard baseline is taken as the tilt direction of the pot.

[0061] It should be noted that if the pot tilts forward at an angle of 15°, the pot will also tilt at the back at the same time, with the same angle of 15°. The difference is that when the pot tilts forward, the front of the bottom of the pot will not leave the hob, while the back of the bottom of the pot will leave the hob, i.e. tilt upward, because the pot tilts forward. Therefore, the direction in which the pot tilts is the side where the edge of the pot is lower than the reference line.

[0062] Specifically, the tilt angle of the pot in the front, back, left, and right directions can be compared with a preset tilt angle threshold. If the tilt angle of the pot is greater than the tilt angle threshold, it indicates that the pot is tilted. At this time, the side of the pot edge lower than the reference line can be used as the tilt direction of the pot. Optionally, the tilt angle threshold can be used to characterize the minimum tilt angle that affects the cooking process. The tilt angle threshold can be adaptively set by those skilled in the art.

[0063] Optionally, in an embodiment of the present invention, an image processing module may be used to generate a tilt array according to the tilt angle of the pot, and the tilt array is used to characterize the tilt angle of the pot in the front-back direction and the left-right direction. Exemplarily, an array may be defined to represent the offset angle in the direction in the form of "direction: offset angle", and the array may store at least one offset angle in a direction, and then the image processing module may send the array to the tilt detection module for determining the tilt direction of the pot, thereby reducing the amount of data transmission and improving the efficiency of determining the tilt direction.

[0064] Optionally, in a specific embodiment, four stove heating areas can be set in the stove in the stove rack of the integrated stove. The stove rack can be divided into four stove heating areas of equal size based on the center point of the stove rack and the straight line where the second image acquisition unit and the third image acquisition unit are located. Figure 2b The first fan-shaped area, the second fan-shaped area, the third fan-shaped area and the fourth fan-shaped area are shown. If the pot is tilted forward, the cooking firepower of the third fan-shaped area and the second fan-shaped area can be increased accordingly, while the cooking firepower of the first fan-shaped area and the fourth fan-shaped area can be reduced. Optionally, the second image acquisition unit can be arranged on the left side of the center point of the grate, and the third image acquisition unit can be arranged on the rear side of the center point of the grate.

[0065] The technical solution of the embodiment of the present invention divides the image of the grate area, characterizes the position information of the pot based on the gap area between the pot and the edge of the grate in each divided image segmentation area, and identifies the edge position information of the pot and the horizontal placement surface information of the grate, and then determines the sliding direction of the pot according to the gap area between the pot and the edge of the grate in each image segmentation area, and performs horizontal detection according to the edge position information and the horizontal placement surface information of the pot, so as to automatically identify the relative position relationship between the pot and the grate, thereby improving the efficiency of pot sliding detection and tilt detection, as well as the intelligence level of the integrated stove.
