Description

Technical Field

[0001] The present invention relates to the technical field of food production, and particularly relates to a rice production method, system and device. Background Art

[0002] With the acceleration of people's living rhythm and the increasing demand for convenience foods, rice, as an important staple food, has an increasing demand for industrial production. In the existing rice production technology, relatively traditional production methods are usually adopted, the process is relatively simple and lacks refined control. However, with the continuous improvement of the market requirements for rice quality, diversification and production efficiency, the existing production technology is gradually difficult to meet the needs.

[0003] However, the existing rice production mostly adopts a segmented process (pre-cooking, steaming, packaging), the equipment in each link is independent, relying on manual connection, and there is a lack of linkage control between equipment. For example, the conveyor belt speed does not match the capacity of the cooking pot, which is likely to cause congestion or idling, resulting in low efficiency and poor consistency. Moreover, the water level, temperature and conveyor speed in the pre-cooking stage are usually fixed values and cannot be dynamically adjusted according to the raw material type (such as brown rice, japonica rice), which is likely to cause uneven water absorption or undercooking or significant differences in the taste of rice in different batches. And when producing in small batches, it will cause waste of water resources. The steaming process depends on preset time or simple temperature control, lacking real-time temperature feedback and dynamic termination mechanism, being prone to overcooking or coking, and being difficult to adapt to various rice varieties. The transfer of raw materials to the cooking pot after pre-cooking, the finished product packaging and other links require manual operation, having the defects of hygienic risks and low quantitative accuracy, and the safety hazards in the high-temperature environment are prominent. The packaging and sorting systems operate independently and require multiple handling, resulting in production capacity bottlenecks and being prone to contamination.

[0004] Therefore, the present invention proposes a rice production method, system and device. Summary of the Invention

Stopping cooking based on the real-time temperature in the cooking pot and the cooking instruction, and ensuring that the cooking effect of rice is just right based on the real-time temperature feedback and dynamic termination mechanism, improving the quality of rice. Using an automatic conveying and quantitative distribution device to realize the efficient transfer, temporary storage and distribution of rice, improving production efficiency. Classifying and conveying the packaged rice products through an automatic sorting system, reducing the health risk, improving the quantitative accuracy, reducing the safety hazard of manual labor in a high-temperature environment, and making the rice products convenient for management and storage, improving the overall work efficiency.

Then, the raw materials fall into the cooking pot through the hopper for heating until it is determined that the raw materials in the cooking pot reach the predetermined gelatinization degree based on the real-time temperature and cooking time in the cooking pot. At this time, stop the current working state of the heating plate and issue a prompt instruction for stopping the cooking process; S3: After receiving the prompt instruction for stopping the cooking process, use an automatic conveying device to transfer the cooked rice to a heat preservation and moisture preservation container, and distribute the rice stored in the heat preservation and moisture preservation container to the automatic packaging production line according to the set weight or volume through a quantitative distribution container; S4: Use a high-speed packaging machine to package and sterilize the rice in the automatic packaging production line to obtain rice products; S5: Classify the rice products according to different specifications and batches through an automatic sorting system and transport them to the finished product storage area; Among them, the raw materials fall into the cooking pot through the hopper for heating until it is determined that the raw materials in the cooking pot reach the predetermined gelatinization degree based on the real-time temperature and cooking time in the cooking pot. At this time, stop the current working state of the heating plate and issue a prompt instruction for stopping the cooking process, including: When the cooking pot receives the cooking instruction, judge whether the loading state in the cooking pot is an empty load state and whether the actual water-to-rice ratio in the cooking pot is within a reasonable range based on the real-time force value of the heating plate and the image of the cooking pot load, and control the heating plate to perform the corresponding working state or issue the corresponding alarm instruction based on the cooking instruction; When the heating plate enters the corresponding working state based on the cooking instruction, obtain the real-time temperature in the cooking pot until it is determined that the raw materials in the cooking pot reach the predetermined gelatinization degree based on the real-time temperature and cooking time in the cooking pot. At this time, stop the current working state of the heating plate and issue a prompt instruction for stopping the cooking process.

[0023] In this embodiment, different pre-cooking processes are adopted according to the specific products required by the product order (for example: white rice or colored rice mixed with miscellaneous grains (brown rice, buckwheat, beans, etc.)). Specifically: after the above raw materials are pre-mixed evenly, they enter the pre-cooking tank at a certain conveying speed. The conveyor belt carries the raw materials above and passes through the pre-cooking tank. By controlling the rotation speed of the conveyor belt, the water level and water temperature in the pre-cooking tank, the raw materials of the specific product to be processed are pre-treated at their specific boiling temperature and time.

[0024] After the conveyor belt carries the raw materials into and through the pre-cooking tank at the set rotation speed, the pre-cooked raw materials are poured into another conveyor belt at the turning point of the conveyor belt (the conveyor belt turns 180° downwards at the drive shaft at the end and then moves back, repeating like a bicycle chain). And the conveyor belt transports them to the equipment hopper; the raw materials fall into the six rice-cooking baskets of the rice cooker through the hopper for heating. The processed raw materials are quantitatively packaged by an automatic packaging machine and enter the sterilizer through the conveyor belt to complete sterilization and post-treatment (that is, after the raw rice is pre-cooked and cooked, the final treatment is completed in the sterilization warehouse to make the product meet the ripening requirements).

[0025] After the products that have completed sterilization are subjected to subsequent physical and chemical, sensory and other inspection items, the entire processing process is completed.

[0026] In this embodiment, the rice cooker: refers to a container for containing rice, water and other rice-cooking materials, usually located above the heating plate and directly contacting the heating plate to receive heat for cooking rice.

[0027] In this embodiment, the rice-cooking instruction: the instruction signal to start the rice-cooking operation. Example: When the user presses the rice-cooking button on the rice cooker, a rice-cooking instruction is issued.

[0028] In this embodiment, the heating plate: a component for providing heat to the rice cooker for cooking rice. Example: The heating part in contact with the bottom of the rice cooker is the heating plate.

[0029] In this embodiment, the real-time force value of the heating plate: the real-time measured value of the pressure borne by the heating plate during operation. Example: The pressure detected by the pressure sensor at a certain moment on the heating plate is the real-time force value.

[0030] In this embodiment, the image of the rice cooker load: an image reflecting the items (rice, water, etc.) loaded inside the rice cooker. Example: The scene inside the rice cooker captured by the camera inside the rice cooker.

[0031] In this embodiment, the loading state: the loading situation of the items (rice, water, etc.) in the rice cooker. Example: It includes different loading degrees such as full, half-full, and a small amount.

[0032] In this embodiment, the no-load state refers to the state where the cooking pot is not loaded with items such as rice and water. For example, the cooking pot is completely empty and there is no material for cooking rice.

[0033] In this embodiment, the actual water-to-rice ratio refers to the ratio of water and rice actually present in the cooking pot. For example, if the weight of water is 500 grams and the weight of rice is 250 grams, the actual water-to-rice ratio is 2:1.

[0034] In this embodiment, the reasonable range refers to the interval of the water-to-rice ratio that is considered suitable for cooking good-quality rice. For example, it is generally considered that the water-to-rice ratio in the range of 1.2:1 to 1.5:1 is a reasonable range.

[0035] In this embodiment, the corresponding alarm instruction refers to a specific alarm indication issued according to different judged abnormal situations. For example, when it is no-load, an alarm instruction of "cooking pot is no-load" is issued, and when the water-to-rice ratio is unreasonable, an alarm instruction of "abnormal water-to-rice ratio" is issued.

[0036] In this embodiment, the working state of the heating plate refers to the current working mode of the heating plate, such as first-stage heating, second-stage heating (with different working powers from the first-stage heating), keeping warm, stopping, etc. For example, the heating plate is in a continuous heating state or an intermittent heating and keeping-warm state.

[0037] In this embodiment, the real-time temperature in the cooking pot refers to the actual temperature inside the cooking pot at a certain moment. For example, it is detected by a temperature sensor that the temperature of the cooking pot at a certain moment during the rice-cooking process is 80 degrees Celsius.

[0038] In this embodiment, the rice-cooking process stop prompt instruction refers to a prompt signal indicating the end of the rice-cooking process. For example, the cooking pot emits a sound or displays a specific icon to prompt that the rice-cooking is completed.

[0039] In this embodiment, the automatic conveying device refers to a device that can automatically complete the transportation and transfer of rice without direct manual operation. For example, a conveyor belt can automatically transport the cooked rice from the rice-cooking area to the heat-preserving and humidity-preserving area.

[0040] In this embodiment, the heat-preserving and humidity-preserving container is a container used to store rice and keep its temperature and humidity within a certain range. For example, a sealed box with a heat-insulating layer and humidity-preserving function.

[0041] In this embodiment, the quantitative distribution container is a container that can accurately distribute rice according to a set amount (weight or volume). For example, a container with scales and a quantitative control device.

[0042] In this embodiment, the set weight or volume refers to the specific weight value or volume value determined in advance for quantitatively distributing rice. For example, it is set that each portion of rice is 500 grams or 500 milliliters.

[0043] In this embodiment, the automated packaging production line is a combination of a series of devices that can automatically complete the rice packaging process. For example, it includes a continuous production line with devices such as automatic bagging and sealing equipment.

[0044] In this embodiment, the high-speed packaging machine is a machine that can quickly package rice. For example, it is a device that can complete the packaging of dozens or even hundreds of portions of rice per minute.

[0045] In this embodiment, the automated sorting system is a system that can automatically classify the packaged rice products according to set conditions (such as specifications and batches). For example, it is a device that classifies by scanning barcodes or identifying packaging features.

[0046] In this embodiment, using the high-speed packaging machine to package the rice in the automated packaging production line to obtain the packaged rice products means using a high-speed operating packaging machine to perform packaging processing on the rice conveyed on the automated packaging production line, and finally obtaining the finished packaged rice. For example, filling a certain amount of rice into a packaging bag and sealing it.

[0047] In this embodiment, using the automated conveying device to transfer the cooked rice to the heat and moisture preservation container, and distributing the rice stored in the heat and moisture preservation container to the automated packaging production line according to the set weight or volume means first using the automatic conveying equipment to transport the cooked rice to the heat and moisture preservation container for temporary storage, and then using the quantitative distribution container to distribute the rice in the heat and moisture preservation container to the automated packaging production line according to the pre-set weight or volume for packaging. For example, the automated conveying device sends the rice to the heat and moisture preservation container, and the quantitative distribution container weighs 500 grams of rice each time and sends it to the packaging production line.

[0048] In this embodiment, using the high-speed packaging machine to package the rice in the automated packaging production line to obtain the packaged rice products is the same as the previous explanation, emphasizing again that the packaging of rice is completed on the production line by the high-speed packaging machine to obtain the finished product.

[0049] In this embodiment, classifying and conveying the packaged rice products to the finished product storage area according to different specifications and batches by the automated sorting system means using the automated sorting system to distinguish the packaged rice according to different standards such as the size of the rice product specifications and production batches, and conveying it to the area specifically for storing finished products. For example, according to the specifications of large and small portions and different production batches, the rice is sent to the corresponding storage locations respectively.

[0050] In this embodiment, through experiments to verify the rice transfer and distribution effects under different conveying speeds and distribution weights, the experiment is designed as follows: Under different conveying speeds and distribution weights, test the performance of the automated conveying device and the quantitative distribution container. The experimental data is as follows:

[0051] Experimental data shows that the automated conveying device can maintain a high transfer efficiency and stability at different conveying speeds. As the conveying speed increases, the transfer efficiency improves, but the stability decreases slightly. This indicates that the automated conveying device can effectively transfer the cooked rice to the heat and moisture preservation container. The quantitative dispensing container can accurately dispense the rice according to the set weight, with a small dispensing error. As the dispensing weight increases, the dispensing error increases slightly. This shows that the quantitative dispensing container can effectively dispense the rice in the heat and moisture preservation container to the automated packaging production line.

[0052] In this embodiment, experiments were conducted to verify the packaging and sorting effects of rice under different packaging speeds and sorting conditions. The experiment was designed as follows: Under different packaging speeds and sorting conditions, the performance of the high-speed packaging machine and the automated sorting system was tested. The experimental data is as follows:

[0053] Experimental data shows that the high-speed packaging machine can maintain a high packaging efficiency and packaging quality at different packaging speeds. As the packaging speed increases, the packaging efficiency improves, but the packaging quality decreases slightly. This indicates that the high-speed packaging machine can effectively package the rice in the automated packaging production line. The automated sorting system can accurately classify the packaged rice products according to different specifications and batches. As the sorting conditions increase, the sorting accuracy rate improves, but the sorting efficiency decreases slightly. This shows that the automated sorting system can effectively classify the packaged rice products and convey them to the finished product storage area.

[0054] In this embodiment, experiments were conducted to compare the differences in taste, nutrition, etc. between the rice produced by using this method and the traditional method. The experiment was designed as follows: Use this rice production method and the traditional method to produce rice respectively, and then compare and analyze the taste, nutrition and other indicators of the rice. The experimental data is as follows:

[0055] Experimental data shows that the rice produced by using the method of the present invention is superior to the rice produced by the traditional method in terms of taste score and nutrient content. This indicates that the method of the present invention can effectively improve the taste and nutritional value of rice.

[0056] The beneficial effects of the above technology are as follows: Determining the type and pre-mixing the raw materials according to the product order can accurately meet the needs of different customers and enhance the adaptability of the product. Precise control of the parameters in the pre-cooking process ensures the stability and standardization of the pre-cooking quality. By judging the loading state of the cooking pot and the water-to-rice ratio, the accuracy of the starting conditions for cooking rice is ensured, and incorrect operations are avoided. Obtaining the temperature of the cooking pot in real time to determine the stop of cooking rice guarantees the cooking effect of the rice and improves the quality of the rice. Utilizing the automated conveying, distributing, packaging, and sorting systems realizes efficient operation throughout the process and improves production efficiency. Overall, this method achieves customization, standardization, and automation in rice production, improves product quality and production efficiency, and reduces the risk of errors.

[0057] Embodiment 2: On the basis of Embodiment 1, when the cooking pot terminal receives a rice cooking instruction, it determines whether the loading state in the cooking pot is an empty state and whether the actual water-to-rice ratio in the cooking pot is within a reasonable range based on the real-time force value of the heating plate and the image of the loading in the cooking pot, and controls the heating plate to perform the corresponding working state or issue a corresponding alarm instruction based on the rice cooking instruction, including: Obtain the real-time force value of the heating plate in real time based on the pressure sensor provided on the heating plate; When receiving the rice cooking instruction, determine in real time whether the loading state in the cooking pot is an empty state based on the real-time force value of the heating plate. If so, issue an empty-load alarm instruction; Otherwise, determine whether the actual water-to-rice ratio in the cooking pot is within a reasonable range based on the real-time force value of the heating plate and the image of the loading in the cooking pot. If so, control the heating plate to perform the corresponding working state based on the rice cooking instruction; Otherwise, issue an alarm instruction indicating that the water-to-rice ratio is unreasonable.

[0058] In this embodiment, it is determined in real time whether the loading state in the cooking pot is an empty state based on the real-time force value of the heating plate: Immediately determine whether there is no load (such as rice, water, etc.) in the cooking pot according to the real-time pressure value borne by the heating plate. For example, if the real-time force value of the heating plate is close to the weight of the cooking pot in a clean state, it is determined that the cooking pot may be in an empty state.

[0059] In this embodiment, the empty-load alarm instruction: A warning signal issued when it is determined that the cooking pot is in an empty state. For example, it may be that the cooking pot emits a continuous beeping sound or displays a specific empty-load warning icon.

[0060] In this embodiment, the alarm instruction indicating that the water-to-rice ratio is unreasonable: A reminder signal issued when it is determined that the ratio of water to rice in the cooking pot is not within a reasonable range. For example, the cooking pot may emit a voice prompt such as "The water-to-rice ratio is abnormal, please adjust" or display a corresponding fault code.

[0061] In this embodiment, the test for judging the water-to-rice ratio is as follows: Design experiment: Measure the real-time force value of the heating plate at different water-to-rice ratios (e.g., 1:1, 1.5:1, 2:1), take images of the contents in the cooking pot, and at the same time, use image analysis software to identify the rice layer and water level height, and calculate the actual water-to-rice ratio. Among them, the experimental data for judging the water-to-rice ratio is as follows:

[0062] It can be seen from the experimental data that there is a certain correlation between the real-time force value of the heating plate and the water-to-rice ratio. As the water-to-rice ratio increases, the real-time force value of the heating plate also increases. This indicates that by measuring the real-time force value of the heating plate, it is possible to effectively determine whether the water-to-rice ratio is within a reasonable range.

[0063] The beneficial effects of the above technology include: Using a pressure sensor to obtain the real-time force value of the heating plate can accurately judge the loading state of the cooking pot, promptly detect the no-load situation and issue an alarm command to avoid damage to the equipment caused by dry burning. In the non-no-load state, further combine the real-time force value and the image of the contents in the cooking pot to judge whether the water-to-rice ratio is reasonable, comprehensively and accurately evaluate the cooking conditions. Control the heating plate to work according to the cooking command for the case where the water-to-rice ratio is reasonable to ensure the normal cooking process. Issue an alarm command for the case where the water-to-rice ratio is unreasonable to remind the user to adjust and improve the cooking quality. It improves the accuracy and reliability of the judgment of the initial conditions in the rice cooking process and effectively prevents the occurrence of abnormal cooking situations.

[0064] Example 3: On the basis of Example 2, judge whether the actual water-to-rice ratio in the cooking pot is within a reasonable range based on the real-time force value of the heating plate and the image of the contents in the cooking pot, including: Determine the total weight of water and rice loaded in the current cooking pot based on the real-time force value of the heating plate; Identify the water level height and the rice layer height distribution data in the current cooking pot based on the image of the contents in the cooking pot; Calculate the actual water-to-rice ratio in the cooking pot based on the water level height and the rice layer height distribution data in the current cooking pot; Judge whether the actual water-to-rice ratio in the cooking pot is within a reasonable range.

[0065] In this example, determine the total weight of water and rice loaded in the current cooking pot based on the real-time force value of the heating plate: Through the real-time pressure value borne by the heating plate, use a certain calculation method or model to deduce the total weight of water and rice in the cooking pot at this time.

[0066] In this example, the water level height in the current cooking pot: The vertical height from the liquid surface of the water in the cooking pot to the bottom of the cooking pot at present. Example: For example, the measured water level height is 2 cm.

[0067] In this embodiment, the rice layer height distribution data: relevant data representing the height changes of the rice layer in different positions in the cooking pot. Example: It may be specific values or distribution graphs describing that some areas of the rice layer are higher and some areas are lower.

[0068] In this embodiment, the actual water-to-rice ratio in the cooking pot is calculated based on the current water level height and the rice layer height distribution data in the cooking pot: Using the currently obtained water level height information and data such as the distribution of the rice layer height, the actual ratio relationship between water and rice is obtained through specific operations or formulas. Example: When the water level height is 3 cm and the average height of the rice layer is 2 cm, the calculated actual water-to-rice ratio is 1.5:1.

[0069] In this embodiment, it is determined whether the actual water-to-rice ratio in the cooking pot is within a reasonable range: The calculated actual water-to-rice ratio is compared with the pre-set reasonable ratio range to determine whether it is within this range. Example: If the pre-set reasonable range is 1.2:1 to 1.5:1 and the calculated actual ratio is 1.6:1, it is determined that it is not within the reasonable range.

[0070] The beneficial effects of the above technologies include: Judging the total weight of water and rice through the real-time force value of the heating plate, providing an intuitive and effective evaluation method. Using image recognition of the cooking pot load to obtain the water level height and the rice layer height distribution data, more detailed internal conditions can be obtained. Calculating the actual water-to-rice ratio based on these data improves the accuracy of ratio judgment. Accurately judging whether the water-to-rice ratio is within a reasonable range helps to ensure the taste and quality of the rice. The accurate judgment of the water-to-rice ratio in rice production is realized, improving the cooking effect and stability.

[0071] Embodiment 4: On the basis of Embodiment 3, the water level height and the rice layer height distribution data in the current cooking pot are recognized based on the cooking pot load image, including: The water level height is recognized based on the cooking pot load image, and the water layer surface image and the rice layer surface image are extracted from the cooking pot load image; All rice grain contours are extracted from the rice layer surface image, and all rice grain lengths are determined based on all the rice grain contours; Based on the distribution positions and the rice grain lengths of all the rice grain contours in the rice layer surface image, the rice layer height gradient feature in the rice layer surface image is analyzed; Based on the water layer surface image, refractive correction is performed on the rice layer height gradient feature to obtain the rice layer height distribution data in the cooking pot.

[0072] In this embodiment, the water level height is recognized based on the cooking pot load image: By analyzing the image of the load in the cooking pot, the height position of the water surface is determined. Example: The water level height is judged by the intersection position of the water and the cooking pot wall in the image.

[0073] In this embodiment, the water layer surface image and the rice layer surface image are extracted from the image of the cooking pot load: from the overall image reflecting the cooking pot load, the image that only shows the surface part of the water and the image that only shows the surface part of the rice are separated. For example, using image processing technology, the parts of the water layer and the rice layer are intercepted respectively.

[0074] In this embodiment, the water layer surface image: an image that only shows the surface condition of the water. For example, in the image, there is only the liquid surface part of the water, without other objects such as rice.

[0075] In this embodiment, the rice layer surface image: an image that only contains the surface condition of the rice. For example, in the image, there is only the appearance of the layer formed by the rice, without the part of the water.

[0076] In this embodiment, all the rice grain contours are extracted from the rice layer surface image: the outer edge shapes of each rice grain are found from the surface image of the rice layer. For example, through image processing algorithms, the general outline of each rice grain is outlined.

[0077] In this embodiment, all the rice grain lengths are determined based on all the rice grain contours: according to the recognized contours of the rice grains, the length dimensions of each rice grain are calculated. For example, the longest distance between the two ends of the rice grain contour is measured as the rice grain length.

[0078] In this embodiment, the rice layer height gradient feature in the rice layer surface image: the characteristics and laws of the gradual change of the rice layer height in the surface image of the rice layer. For example, it may be the trend that the rice layer gradually rises or falls from one end to the other end.

[0079] In this embodiment, the refractive correction is performed on the gradient feature of the rice layer height based on the image of the water layer surface to obtain the rice layer height distribution data in the cooking pot: by using the image information of the water layer surface, the refractive effect of water on the gradient feature of the rice layer height is corrected and adjusted, so as to obtain accurate data on the rice layer height distribution in the cooking pot. For example, since the refraction of water will cause deviation in the observed rice layer height, this deviation is corrected through the relevant parameters of the water layer image and the preset refractive correction model to obtain the real rice layer height distribution. Among them, the "refractive correction model" is a mathematical model or algorithm used to correct the deviation of the rice layer height observation caused by the refraction of water. The training samples required to build this refractive correction model may include: a large number of cooking pot images taken under different conditions (such as different water layer thicknesses, water qualities, types and distributions of rice, etc.), and at the same time, the real rice layer height and water layer related parameters (such as thickness, refractive index, etc.) in these images need to be accurately measured. By inputting these images and the corresponding real measurement data as training samples into the model, the model can learn the refractive law of water and its influence on the rice layer height observation, so that it can accurately correct the gradient feature of the rice layer height according to the new water layer surface image information in subsequent use and obtain more accurate rice layer height distribution data.

[0080] The beneficial effects of the above technology include: identifying the water level height through the image of the cooking pot load and extracting the images of the water layer and the rice layer surface, which provides a basis for subsequent analysis. Extracting the rice grain contours and determining the rice grain lengths in the rice layer surface image helps to analyze the rice layer condition more finely. Analyzing the gradient feature of the rice layer height can comprehensively understand the distribution of the rice layer. Performing refractive correction on the gradient feature of the rice layer height improves the accuracy of the rice layer height distribution data. The accurate identification of the water level height and the rice layer height distribution data in the cooking pot is realized, which provides strong support for accurately judging the water-rice ratio, thus improving the quality and stability of rice production.

[0081] Embodiment 5: On the basis of Embodiment 4, based on the distribution positions and rice grain lengths of all the rice grain contours in the rice layer surface image, the gradient feature of the rice layer height in the rice layer surface image is analyzed, including: Based on the size relationship of the rice grain lengths between each rice grain contour and its corresponding adjacent rice grain contour in the rice layer surface image, a compliance mark is made for the line segment between the physical center of each rice grain contour and the physical center of its corresponding adjacent rice grain contour, and the symbol marked image corresponding to the rice layer surface image is obtained; Connect and mark all the line segments between the rice grains that are continuously adjacent and have the same marked symbol in the symbol marked image corresponding to the rice layer surface image to obtain all the initial recognition gradient direction broken lines of the rice layer surface image; Summarize two initial recognized gradient direction broken lines in the rice layer surface image whose shortest distance between endpoints does not exceed the preset distance and whose marking symbols are the same into a combination of to-be-judged gradient direction broken lines in the rice layer surface image, and obtain all combinations of to-be-judged gradient direction broken lines in the rice layer surface image; Calculate the connectable index of each combination of to-be-judged gradient direction broken lines in the rice layer surface image; Connect the two initial recognized gradient direction broken lines included in all combinations of to-be-judged gradient direction broken lines whose connectable index is not less than the preset connectable index threshold to obtain the exhaustive recognized gradient direction broken lines; Based on all the exhaustive recognized gradient direction broken lines in the rice layer surface image and all the initial recognized gradient direction broken lines except those included in all the exhaustive recognized gradient direction broken lines, regard them as all the effective gradient direction broken lines in the rice layer surface image; Analyze the rice layer height gradient feature in the rice layer surface image based on all the effective gradient direction broken lines in the rice layer surface image.

[0082] In this embodiment, the rice grain contour and each corresponding adjacent rice grain contour.

[0083] In this embodiment, the size relationship of the rice grain lengths between each rice grain contour and each corresponding adjacent rice grain contour.

[0084] In this embodiment, based on the size relationship of the rice grain lengths between each rice grain contour and each corresponding adjacent rice grain contour in the rice layer surface image, mark the line segment between the physical center of each rice grain contour and the physical center of each corresponding adjacent rice grain contour.

[0085] In this embodiment, the rice grain contour and each corresponding adjacent rice grain contour: In the rice layer surface image, the contour of one rice grain and the contours of other rice grains directly adjacent to it. Example: For example, the contour of a round rice grain and the contour of another rice grain next to it.

[0086] In this embodiment, the size relationship of the rice grain lengths between each rice grain contour and each corresponding adjacent rice grain contour: Compare the actual size of the rice grain lengths represented by one rice grain contour and the adjacent rice grain contour. Example: If the length of a certain rice grain is 5 millimeters and the length of its adjacent rice grain is 4 millimeters, then the rice grain length of 5 millimeters being greater than the length of its adjacent rice grain of 4 millimeters is a size relationship.

[0087] In this embodiment, based on the size relationship of the rice grain lengths between each rice grain contour and its corresponding adjacent rice grain contour in the rice layer surface image, specific markings are made for the line segments between the physical centers of each rice grain contour and its corresponding adjacent rice grain contour: According to the above-mentioned size relationship of the rice grain lengths, specific markings are made for the line segments connecting the center points of each rice grain contour and the center points of adjacent rice grain contours. For example, if the length of rice grain A is greater than the length of adjacent rice grain B, it may be marked as "+", and vice versa as "-".

[0088] In this embodiment, all the initial recognized gradient direction broken lines of the rice layer surface image: The broken lines representing the height change trend in the rice layer surface image preliminarily determined through certain image processing and analysis methods. For example, they may be some broken lines pointing from higher positions to lower positions in the rice layer.

[0089] In this embodiment, the shortest distance between endpoints: Refers to the minimum value among the distances between different endpoints of two line segments.

[0090] In this embodiment, the preset distance: The distance value set in advance for judgment and comparison. For example, the preset distance is set to 2 cm to determine whether the distance between the endpoints of a line segment meets the requirements.

[0091] In this embodiment, the connectable index of each combination of gradient direction broken lines to be judged: A quantitative index used to measure whether two line segments to be judged can be connected into a gradient direction broken line. For example, the higher the connectable index, the more likely it is that these two line segments belong to the same gradient direction.

[0092] In this embodiment, the preset connectable index threshold: The critical value of the connectable index set in advance. For example, when the connectable index is greater than this threshold, it is considered that the corresponding line segment combination can be connected.

[0093] In this embodiment, the exhaustive recognized gradient direction broken line: The gradient direction broken line that is finally determined to be as long or complete as possible through a series of judgment and connection operations. For example, through screening and connection, a broken line segment that can accurately reflect the height gradient direction of the rice layer is obtained.

[0094] The beneficial effects of the above technology include: By symbolically marking the relationships between the outlines of rice grains, it provides preliminary data processing for analyzing the gradual change characteristics of the rice layer height. Obtaining the initial recognition of the gradual change direction broken line of the symbol-marked image helps to preliminarily determine the possible change trend of the rice layer. Through operations such as combining line segments, calculating and connecting indices, more accurate and exhaustive recognition of the gradual change direction broken lines can be screened out. Determining the effective gradual change direction broken lines can more precisely analyze the gradual change characteristics of the rice layer height. Based on these precise analysis results, the water-rice ratio can be judged more accurately, improving the cooking quality of the rice. It improves the accuracy and reliability of the analysis of the gradual change characteristics of the rice layer height, providing more accurate data support for judging the water-rice ratio in the rice production process.

[0095] Embodiment 6: On the basis of Embodiment 5, calculate the connection index of each combination of gradual change direction broken lines to be judged in the rice layer surface image, including: Smoothly fit the two initial recognition gradual change direction broken lines included in each combination of gradual change direction broken lines to be judged in the rice layer surface image to obtain the connecting line segment between the two initial recognition gradual change direction broken lines included in each combination of gradual change direction broken lines to be judged in the rice layer surface image; Determine the quantity, area, and shape factor of all rice grain outlines passed by the connecting line segment between the two initial recognition gradual change direction broken lines included in each combination of gradual change direction broken lines to be judged in the rice layer surface image, and determine the number of complete rice grain outlines among all rice grain outlines passed by the connecting line segment between the two initial recognition gradual change direction broken lines included in each combination of gradual change direction broken lines to be judged in the rice layer surface image; Based on the quantity, area, shape factor of all rice grain outlines passed by the connecting line segment between the two initial recognition gradual change direction broken lines included in each combination of gradual change direction broken lines to be judged in the rice layer surface image, the number of complete rice grain outlines among all rice grain outlines, and the length of the corresponding connecting line segment, calculate the connection index of each combination of gradual change direction broken lines to be judged in the rice layer surface image: ; In the formula, is the connection index of the currently calculated combination of gradual change direction broken lines to be judged in the rice layer surface image, is the preset weight of the distribution density in terms of length of all rice grain outlines passed by the connecting line between the two initial recognition gradual change direction broken lines included in the currently calculated combination of gradual change direction broken lines to be judged, is the quantity of all rice grain outlines passed by the connecting line segment between the two initial recognition gradual change direction broken lines included in the currently calculated combination of gradual change direction broken lines to be judged, is the number of complete rice grain contours among all the rice grain contours on the connection line segment path between two initially recognized gradient direction broken lines included in the gradient direction broken line combination to be judged for the current calculation. is the length of the connection line between two initially recognized gradient direction broken lines included in the gradient direction broken line combination to be judged for the current calculation. is the preset weight of the distribution density in terms of area of all the rice grain contours on the connection line path between two initially recognized gradient direction broken lines included in the gradient direction broken line combination to be judged for the current calculation. is the average area of all the rice grain contours passed by two initially recognized gradient direction broken lines included in the gradient direction broken line combination to be judged for the current calculation. is the area of the i-th rice grain contour on the connection line path between two initially recognized gradient direction broken lines included in the gradient direction broken line combination to be judged for the current calculation. is the shape coefficient of the i-th rice grain contour on the connection line path between two initially recognized gradient direction broken lines included in the gradient direction broken line combination to be judged for the current calculation.

[0096] In this embodiment, the two initially recognized gradient direction broken lines included in each gradient direction broken line combination to be judged in the rice layer surface image are smoothly fitted to obtain the connection line segment between the two initially recognized gradient direction broken lines included in each gradient direction broken line combination to be judged in the rice layer surface image: Using mathematical methods to make the two preliminarily determined gradient direction broken lines smoother and more continuous, so as to obtain the connection line segment between them. Example: The endpoints of two broken lines are A and B respectively, and a smooth curve from A to B is obtained through fitting, and this curve is the connection line segment.

[0097] In this embodiment, the shape coefficient of the rice grain contour: A numerical index used to describe the shape characteristics of the rice grain contour, which can reflect, for example, the plumpness and slender degree of the rice grain. Example: The shape coefficient may be calculated based on parameters such as the length and width of the rice grain. The shape coefficient of the rice grain can be calculated based on its length, width and other parameters in various ways. For example, it can be calculated based on a complex mathematical model, comprehensively considering parameters such as the length, width, thickness of the rice grain, and even the curvature of the rice grain contour, through the calculation of a multivariate function. Which method to specifically adopt depends on the accuracy requirement for the description of the rice grain shape and the complexity of the calculation.

[0098] In this embodiment, the number of complete rice grain contours: The number of completely undamaged or complete rice grain contours in a certain specific area or range. Example: If there are a total of 100 rice grain contours in the observed rice layer area, and 80 of them are complete, then the number of complete rice grain contours is 80.

[0099] In this embodiment, the preset weight of the distribution density in terms of length of all rice grain outlines on the connection line path between the two initially recognized gradient direction broken lines included in the gradient direction broken line combination to be judged: a value preset under the premise of considering the length of the rice grains, which is used to measure the influence degree of the distribution density of the rice grains passing through the connection line on the connection line segment on the overall judgment. Example: Suppose the preset weight is 0.3, which means that the distribution density determined based on the length has a certain but not decisive influence on the final judgment.

[0100] In this embodiment, the preset weight of the distribution density in terms of area of all rice grain outlines on the connection line path between the two initially recognized gradient direction broken lines included in the gradient direction broken line combination to be judged: a value preset under the premise of considering the area of the rice grains, which is used to measure the influence degree of the distribution density of the rice grains passing through the connection line on the connection line segment on the overall judgment. Example: The preset weight is 0.2, indicating that the influence of the distribution density determined based on the area is relatively small in the judgment.

[0101] The beneficial effects of the above technology include: By performing smooth fitting on the gradient direction broken line combination to be judged, a connection line segment is obtained, which provides a basis for the calculation of the connectable index. Parameters such as the number, area, shape coefficient, and the number of complete rice grain outlines of the rice grain outlines passed by the connection line segment are determined, enabling the calculation of the connectable index to consider multiple factors. Calculating the connectable index based on these detailed parameters and preset weights can accurately quantify the connection possibility of the gradient direction broken line combination to be judged. The accurate connectable index helps to more scientifically screen out effective gradient direction broken line combinations, thereby more accurately analyzing the gradient characteristics of the rice layer height. It improves the accuracy and scientific nature of the connectable index calculation, providing a reliable basis for accurately judging the gradient characteristics of the rice layer height and the water-rice ratio.

[0102] Embodiment 7: On the basis of Embodiment 5, analyze the gradient characteristics of the rice layer height in the rice layer surface image based on all effective gradient direction broken lines in the rice layer surface image, including: Determine the change sequence of the rice grain length difference in the corresponding gradient direction of each effective gradient direction broken line in the rice layer surface image; Based on the change sequence of the rice grain length difference in the corresponding gradient direction of each effective gradient direction broken line in the rice layer surface image, identify all actual gradient direction broken lines among all the effective gradient direction broken lines in the rice layer surface image; Regard the change sequence of the rice grain length difference in the corresponding gradient direction of the rice layer surface image on all actual gradient direction broken lines as the gradient characteristics of the rice layer height in the rice layer surface image.

[0103] In this embodiment, the gradient direction corresponding to the effective gradient direction polyline: the direction of the height change of the rice layer indicated by the effective gradient direction polyline determined to be effective. Example: For example, if an effective gradient direction polyline is from the upper left corner to the lower right corner, then the corresponding gradient direction is from the upper left corner to the lower right corner.

[0104] In this embodiment, to determine the sequence of changes in the rice grain length differences in the corresponding gradient direction of each effective gradient direction polyline on the rice layer surface image: find out the order of the differences between adjacent rice grain lengths along the gradient direction of each effective gradient direction polyline. Example: On a certain effective gradient direction polyline, from one end to the other end, the adjacent rice grain length differences are 1 mm, 2 mm, -0.5 mm, etc. in sequence, which constitutes a sequence of changes in the rice grain length differences.

[0105] In this embodiment, based on the sequence of changes in the rice grain length differences in the corresponding gradient direction of each effective gradient direction polyline on the rice layer surface image, all actual gradient direction polylines are identified among all the effective gradient direction polylines of the rice layer surface image: According to the characteristics and patterns of the obtained sequence of changes in the rice grain length differences, among all the effective gradient direction polylines considered to be effective, the polylines that truly reflect the actual height change trend of the rice layer are distinguished. It can be identified by using a pre-trained actual gradient direction polyline screening model. By inputting the sequence of changes in the rice grain length differences in the corresponding gradient direction of each effective gradient direction polyline on the rice layer surface image and the distribution positions of all the effective gradient direction polylines included in the rice layer surface image into the pre-trained actual gradient direction polyline screening model, all actual gradient direction polylines can be identified.

[0106] Among them, the "actual gradient direction polyline screening model" is a model used to accurately identify the actual gradient direction polylines from the effective gradient direction polylines of the rice layer surface image. During the process of training this model, the required training samples may include a large number of rice layer surface images in different situations. Each training sample should contain the following information: 1. Detailed data of the sequence of changes in the rice grain length differences in the corresponding gradient direction of each effective gradient direction polyline in the rice layer surface image. 2. The specific distribution positions of all the effective gradient direction polylines in the rice layer surface image. 3. Clearly marked which are the actual gradient direction polylines that truly reflect the actual height change trend of the rice layer and which are not. By using a large number of such training samples with accurate markings and detailed information to train the model, the model can learn the internal relationships and patterns between the sequence of changes in the rice grain length differences, the polyline distribution positions, and the actual gradient direction polylines, so as to accurately identify the actual gradient direction polylines in the new input data.

[0107] In this embodiment, the actual gradient direction polyline: The gradient direction polyline that can accurately represent the true height change trend of the rice layer. Example: After analyzing multiple polylines, the polylines that finally match the actual rice layer height change are the actual gradient direction polylines.

[0108] The beneficial effects of the above technologies include: determining the change sequence of the rice grain length difference, providing specific data basis for analyzing the gradient characteristics of the rice layer height. Identifying the actual gradient direction polyline based on this sequence can accurately screen out the line segments related to the rice layer height change. Taking the change sequence of the rice grain length difference on all actual gradient direction polylines as the gradient characteristics of the rice layer height comprehensively and accurately describes the height change of the rice layer. It helps to more accurately judge the water-rice ratio, thereby optimizing the cooking process and quality of the rice. It improves the accuracy and comprehensiveness of the analysis of the gradient characteristics of the rice layer height, providing more reliable technical support for rice production.

[0109] Embodiment 8: On the basis of Embodiment 1, S2: When the heating plate enters the corresponding working state based on the cooking instruction, obtain the real-time temperature in the cooking pot until it is determined that the raw materials in the cooking pot reach the predetermined gelatinization degree based on the real-time temperature in the cooking pot and the cooking time, then stop the current working state of the heating plate and issue a cooking process stop prompt instruction, including: When the heating plate enters the corresponding working state based on the cooking instruction, obtain the real-time temperature in the cooking pot; When the real-time temperature in the cooking pot reaches the preset temperature in the container or the current heated time reaches the preset heating time corresponding to the cooking instruction, then stop the current working state of the heating plate and issue a cooking process stop prompt instruction.

[0110] In this embodiment, the preset temperature in the container: A specific temperature value set in advance in the cooking pot, used to judge whether the cooking process is completed or enters a specific stage. Example: The preset temperature in the container may be 103 degrees Celsius. When the temperature of the cooking pot reaches this value, it is considered that the cooking is completed.

[0111] In this embodiment, the current heated time: The length of time elapsed from the start of heating to the current moment. Example: If the heating has been carried out for 20 minutes, then the current heated time is 20 minutes.

[0112] In this embodiment, the preset heating time corresponding to the cooking instruction: The expected heating time length set according to different cooking instructions (such as cooking different amounts of rice or different cooking modes). Example: The preset heating time for cooking 2 cups of rice may be 30 minutes.

[0113] In this embodiment, the real-time temperature in the cooking pot is obtained: through devices such as temperature sensors, the temperature value of the cooking pot at the current moment is measured and obtained in real time. For example, elements such as thermocouples or thermistors are used to obtain the real-time temperature in the cooking pot. For example, the temperature measured at the current moment is 85 degrees Celsius.

[0114] In this embodiment, the gelatinization degree of rice at different temperatures and times can be verified through the following test data to determine whether the cooking is completed: Design an experiment: cook rice at different heating times and temperatures, and measure indicators such as the hardness and moisture content of the rice. The experimental data is as follows:

[0115] The experimental data shows that the heating time and real-time temperature have a significant impact on the hardness of the rice. As the heating time and temperature increase, the hardness of the rice also increases. By controlling the heating time and temperature, it is possible to effectively determine whether the rice is cooked and avoid overheating resulting in overcooked rice.

[0116] The beneficial effects of the above technology include: by obtaining the real-time temperature of the cooking pot, the progress and status of rice cooking can be grasped in a timely manner. When the preset temperature in the container or the preset heating time is reached, the heating plate stops working, ensuring precise control of the cooking process. It avoids problems such as rice being burned due to too high temperature or too long heating time, ensuring the quality of the rice.
