Detailed Description
The technical solution of the present invention is further illustrated by the following examples.
Example 1.
A method for controlling a cooking target temperature based on pattern recognition, as shown in fig. 1, comprises the steps of,
s1, identifying different cooking modes;
s2, obtaining a cooking target temperature corresponding to the identified cooking mode;
and S3, regulating and controlling the output power of the cooker to work at the cooking target temperature.
According to the method, on the basis of recognizing the cooking mode, the cooking target temperature corresponding to the cooking mode is obtained, and the output power of the cooker is regulated according to the obtained cooking target temperature so as to realize working at the cooking target temperature. The method disclosed by the invention is matched with the actual situation of the cooking mode, and the control on the kitchen range is more accurate and effective.
Specifically, the cooking mode is a dry pot cooking mode, a water cooking mode, or an oil cooking mode. The dry pot cooking mode is that the cooker has no other medium or only a small amount of water or oil, and in the dry pot cooking mode, the amount of water or oil in the cooker is only a small amount, and the water or oil cannot meet the requirements of water boiling or frying. The water cooking mode refers to that the water is used as a medium in the cooker to cook food, such as water boiling. The oil cooking mode refers to that the cooking utensil cooks food by taking oil as a medium, such as frying.
Specifically, step S1 identifies the cooking mode from the temperature information of cooking. The recognition of the cooking mode is recognized based on temperature information of cooking. The temperature change information over a period of time is different in different cooking modes. By analyzing the temperature information over a period of time, a cooking pattern may be identified. The selection of the specific time period can be flexibly determined according to actual needs. The specifically selected time period is typically expressed in terms of a sampling time period.
The temperature information of cooking is temperature information in a sampling time period, and the temperature time information in this embodiment is continuous temperature information in the sampling time period. The temperature information in the sampling time period at least comprises at least one of interval temperature change information, interval temperature slope change information, instantaneous temperature information at specific time in the sampling time period and instantaneous temperature slope information. It should be noted that other information, such as variance information and mean information, may also be obtained according to the temperature information to provide a judgment basis for different identification methods.
The obtained continuous temperature information in the sampling time period can be represented by a temperature-time curve, a slope-time curve can be formed on the basis of the temperature-time curve, and a temperature/slope-time curve relation can be formed in a graph by taking time as an abscissa and taking temperature and slope as ordinate respectively.
Based on the same cooking mode, the temperature and slope change in the cooker in the sampling time period satisfy the corresponding rules. By sampling the temperature information within the time period, a specific cooking mode can be determined.
For example, taking the temperature inside the cooker as an example, in the dry pot cooking mode, taking the cooker as an example that no other operation is performed before the dry pot cooking mode starts, during the dry pot cooking mode is started, the temperature inside the cooker rises with the increase of the heating time within a period of time just before the start, the slope corresponding to the temperature change also satisfies a certain range, and when the temperature inside the cooker reaches T1, the temperature inside the cooker is basically kept within the range of T1 with the increase of the heating time, and a stable state is reached. Generally, in the steady state of the dry pot cooking mode, the temperature in the cooker is kept in the range of 175 ℃ to T1 to 190 ℃.
Taking the water cooking mode as an example, in the water cooking mode, the temperature in the cooker rises with the increase of the heating time within a period of time when the heating is just started, the slope of the temperature change in the cooker in the water cooking mode satisfies a corresponding range, and when the temperature in the cooker reaches T2, the temperature in the cooker is basically kept near T2 with the increase of the heating time, and a steady state is reached. In a stable state of a normal water cooking mode, the temperature in the cooker is kept within the range of more than or equal to 95 ℃ and less than or equal to T2 and less than or equal to 105 ℃.
Taking the oil cooking mode as an example, in the oil cooking mode, the temperature in the cooker rises with the increase of the heating time during the period of time when the heating is just started, the slope of the temperature change in the cooker in the oil cooking mode satisfies the corresponding range, and when the temperature in the cooker reaches T3, the temperature in the cooker is basically maintained around T3 with the increase of the heating time. In a normal stable state of the oil cooking mode, the temperature in the cooker is kept within the range of 140 ℃ to T3 to 170 ℃.
Therefore, according to the temperature and slope conditions within the sampling period, the cooking mode within the cooker can be identified.
It should be noted that, the cooking mode identification generally adopts the analysis of temperature information within a period of time, the length of the sampling time is generally greater than 20 seconds, and the instantaneous temperature information less than 20 seconds is not used.
It should be noted that the cooking mode may be identified by judging and identifying the detected temperature change performance, or may be identified by a commercially available mode identification component, and those skilled in the art can select a desired model, which is not described herein in detail.
The detection of the temperature information of the cooking may be obtained by the temperature detection module. The temperature detection module can be implemented by selecting a temperature sensor or a temperature detection device, and can be implemented by selecting an infrared temperature sensor or a thermocouple or other devices capable of detecting temperature. The skilled person can select the required temperature detection module according to the requirements of the present technical solution, which is not listed here.
Specifically, in step S2, after the cooking mode is identified, the cooking target temperature corresponding to the identified cooking mode is found from the relationship information between the pre-stored cooking mode and the cooking target temperature. The cooking modes are different, and the cooking target temperature required by the corresponding cooker is different. For example, dry-pot cooking, a relatively higher target temperature for cooking than is required for the water cooking mode. According to the method, the needed cooking target temperature is obtained through the recognition of the cooking mode, the cooking target temperature obtained by the method is more consistent with the actual cooking mode, and the blindness in the prior art is avoided.
After the cooking target temperature corresponding to the cooking mode is obtained through the step S2, the step S3 is entered, and the output power of the cooker is regulated and controlled to work at the cooking target temperature, specifically: and detecting the actual cooking temperature in real time, and adjusting the output power of the cooker in real time according to the temperature difference between the actual cooking temperature and the cooking target temperature to realize working at the cooking target temperature.
When the temperature difference between the actual cooking temperature and the cooking target temperature is larger than a certain upper limit value, the upper limit value is represented by a first threshold value, and the cooker is adjusted to output high-level power; and when the temperature difference between the actual cooking temperature and the cooking target temperature is less than a certain lower limit value, expressing the lower limit value by using a second threshold value, and adjusting the cooker to output low-gear power.
The reference principle of regulating and controlling the output power of the cooker is that the larger the temperature difference between the actual cooking temperature and the cooking target temperature is, the lower the output gear of the cooker is regulated; the smaller the temperature difference is, the lower the gear is; and when the temperature difference is smaller than a second threshold value, the cooker works at a low gear. And when the actual cooking temperature is equal to the target cooking temperature, adjusting the cooker to work at a low gear.
It should be noted that the first threshold is a relatively large value, and the second threshold is a relatively small value. The skilled person should know that, the first threshold and the second threshold are listed here as objects of temperature difference comparison, and the objects of temperature difference comparison are not limited to only two thresholds, and only two thresholds may be set as required, or one or more other thresholds between the first threshold and the second threshold may be set as required as a basis for determining the power output gear of the range. It should be noted that, as those skilled in the art should also know, the cooking range here lists two gears, namely, a high gear and a low gear, but does not mean that the cooking range has only two gears, and two gears may be provided, or multiple gears may be provided as needed.
It should be noted that, the method of the present invention may select, using the temperature in the cooker as a standard, detect the temperature information in the cooker, identify the cooking mode, obtain the cooking target temperature also for the cooking temperature in the cooker, and obtain the difference between the actual cooking temperature and the cooking target temperature also for the temperature in the cooker.
Alternatively, the temperature information of the outer surface of the cooker is detected by taking the temperature of the outer surface of the cooker as a standard, the cooking mode is identified, the obtained cooking target temperature is also the cooking temperature of the outer surface of the cooker, and the difference value between the actual cooking temperature and the cooking target temperature is also the temperature of the outer surface of the cooker.
Alternatively, the temperature information at the outer surface of the cooker is detected by taking the temperature in the cooker as a standard, the temperature information at the outer surface of the cooker is compensated to obtain the temperature relative to the temperature in the cooker, the mode identification is carried out on the basis of the relation between the temperature in the cooker and the cooking mode, the cooking target temperature in the cooker is obtained, and the output power of the cooker is adjusted according to the difference between the cooking target temperature and the actual cooking temperature. Of course, the temperature inside the cooker can also be compensated to obtain the temperature information corresponding to the outer surface of the cooker, the pattern recognition is carried out based on the relation between the temperature at the outer surface of the cooker and the cooking pattern, the cooking target temperature at the outer surface of the cooker is obtained, and the output power of the cooker is adjusted according to the difference between the cooking target temperature and the actual cooking temperature.
The temperature information detection position is inside the cooker, outside the cooker or other positions, which does not affect the technical scheme of the patent. And correspondingly selecting the stored temperature data information corresponding to the cooking mode and the detection position to obtain the cooking target temperature based on the corresponding position, converting the obtained cooking target temperature of a certain basic position to obtain the cooking target temperature based on other positions, and adjusting the output power of the cooker according to the difference between the cooking target temperature and the actual cooking temperature.
The invention relates to a method for acquiring a cooking target temperature based on pattern recognition. By identifying different cooking modes, the cooking target temperature corresponding to the identified cooking mode is obtained, and the output power of the cooker is regulated and controlled to work at the cooking target temperature. The method can regulate and control the cooking target temperature which accords with the actual cooking mode and output by the cooker, and realizes high-quality operation of cooking.
Example 2.

The temperature or the temperature slope at different sampling moments is obtained, and judgment is carried out according to each sampling point, so that the cooking mode can be identified, and the sampling workload can be reduced.

The influencing factor of the temperature compensation information is at least one of cooker information, heat conversion efficiency of the cooker and food material condition. The temperature compensation information relationship under different influence factors is obtained in advance, temperature compensation information suitable for actual use conditions is obtained by combining actual cooking conditions, and the detected temperature information is compensated.
The current actual use situation can be obtained through imaging judgment or through user input of the current use situation.
According to the method for controlling the cooking target temperature based on the pattern recognition, the compensation based on the actual use situation is performed on the detected temperature information, the obtained temperature information is more accurate, and the control on the output power of the cooker is more accurate.

Wherein the cooking mode is a dry pot cooking mode, a water cooking mode, or an oil cooking mode.

And the main control module obtains the cooking target temperature corresponding to the identified cooking mode according to the corresponding relation between the cooking mode and the cooking target temperature. The relationship between the cooking pattern stored in the storage unit and the cooking target temperature may be a relationship obtained through a previous experiment or a relationship of a fitting curve obtained based on a previous test result.
The cooking modes are different, the cooking target temperatures required by the corresponding cookers are different, and the control on the power output of the cooker is also different. For example, an oil cooking mode may require a relatively higher cooking target temperature than a water cooking mode. According to the invention, the required cooking target temperature is obtained by identifying the cooking mode, the obtained cooking target temperature is more consistent with the actual cooking mode, and the blindness in the prior art is avoided.
