Example 1
In this embodiment, the intelligent cooking apparatus may cook various dishes, such as chicken steaks, french fries, and the like. For each dish, the intelligent cooking device is provided with standard cooking parameters such as standard cooking temperature, standard cooking duration, standard dish amount, and the like, for example: for the fried chicken, the standard cooking parameters set by the intelligent cooking equipment are 200g of chicken, the cooking temperature is 200 ℃ and the cooking time is 5min; for french fries, standard cooking parameters set by the intelligent cooking equipment are 200g of potato, the cooking temperature is 180 ℃, and the cooking time is 5min. If the cooking effect of the intelligent cooking equipment reaches the standard, the intelligent cooking equipment fries 200g of chicken for 5min according to the cooking temperature of 200 ℃, golden fried chicken chops will be fried, and the intelligent cooking equipment fries 200g of potatoes for 5min according to the cooking temperature of 180 ℃, golden fried potato chips will be fried; if the cooking effect of the intelligent cooking device is not up to standard, such as the heating effect is too high, the intelligent cooking device fries 200g chicken for 5 minutes according to the cooking temperature of 200 ℃, the intelligent cooking device fries dark brown fried chicken chops, and the intelligent cooking device fries 200g potatoes for 5 minutes according to the cooking temperature of 180 ℃, and the intelligent cooking device fries dark brown fried potato chips. Therefore, whether the cooking effect of the intelligent cooking equipment reaches the standard or not needs to be checked, so that the quality of cooked dishes is poor due to the fact that the intelligent cooking equipment which does not reach the standard is adopted for cooking.
In this embodiment, the intelligent cooking appliance includes a computer readable storage medium and a processor coupled to each other, the computer readable storage medium having a computer program stored thereon. In order to conveniently check whether the cooking effect of the intelligent cooking appliance is up to standard, a computer program on a computer readable storage medium of the intelligent cooking appliance is executed by a processor to implement a training method for an artificial neural network as shown in fig. 1, before cooking, as follows:
under the condition that whether the cooking effects of other intelligent cooking devices reach the standards or not is known, the other intelligent cooking devices are enabled to cook the fried chicken and the fried potato strips respectively, wherein for the same dishes, the other intelligent cooking devices are enabled to execute the cooking starting programs respectively so as to cook according to different cooking parameters, for example: the cooking effect of the first intelligent cooking equipment is known to reach the standard, and the first intelligent cooking equipment is made to fry 200g of chicken and 200g of potatoes for 5min according to the cooking temperature of 200 ℃; the cooking effect of the second intelligent cooking equipment is known to reach the standard, and the second intelligent cooking equipment is made to fry 200g of chicken and 200g of potatoes for 5min according to the cooking temperature of 180 ℃; the cooking effect of the third intelligent cooking device is known to be not up to the standard (the cooking effect is too high), so that the third intelligent cooking device respectively fries 250g of chicken and 250g of potatoes for 5min according to the cooking temperature of 200 ℃; the cooking effect of the fourth intelligent cooking device is known not to reach the standard (the cooking effect is too low), so that the fourth intelligent cooking device can fry 200g of chicken and 200g of potatoes for 8min … … respectively according to the cooking temperature of 200 ℃; the following sample acquisition steps are then performed for each cooking session to obtain a plurality of sets of learning samples, wherein the sample acquisition steps performed for each cooking session are as follows A, B, C, D:
A. after the intelligent cooking equipment executes a cooking starting program for cooking, the cooking temperature, the cooking time and the dish quantity obtained from the cooking starting program are used as cooking parameters in the cooking process;
B. shooting the cooked dishes to obtain dish images capable of reflecting the cooking degree of the dishes, wherein: in the dish image with proper dish curing degree, the dishes are golden yellow; in the dish image with the too high degree of cooking, the dishes are in a scorched black; in the dish image with low dish curing process, the dishes are light white;
C. identifying the type of the dishes according to the dish image; the dish shape of the fried chicken chops is disc-shaped, and the dish shape of the french fries is strip-shaped, so that whether the dish varieties are fried chicken chops or french fries can be identified from the dish shape in the dish image;
D. the cooking parameters, the dish images and the dish variety types are used as input signals, and whether the cooking effect of the intelligent cooking equipment meets the standard or not is used as an output signal, so that a group of learning samples for the artificial neural network to carry out cooking effect checking training are formed.
Since the cooking effect of the first intelligent cooking device is up to standard and the first intelligent cooking device fries 200g chicken and 200g potato for 5 minutes according to a cooking temperature of 200 ℃, the chicken steaks in the dish image should be golden yellow and the french fries should be dark brown (since the actual cooking temperature of french fries is greater than the standard cooking temperature). Therefore, in the input signals of the first group of learning samples, the cooking parameters are 200g of chicken, the cooking temperature is 200 ℃ and the cooking time is 5min, the dish images are golden yellow, the dish types are fried chicken chops, and the output signals are the cooking effect reaching standards; in the input signals of the second group of learning samples, the cooking parameters are 200g of potatoes, the cooking temperature is 200 ℃ and the cooking time is 5min, the dish images are in a dark brown color, the dish varieties are French fries, and the output signals are the cooking effect reaching the standard.
Since the cooking effect of the second intelligent cooking device also meets the standard, and the second intelligent cooking device fries 200g chicken and 200g potato for 5 minutes according to the cooking temperature of 180 ℃, the fries in the dish image should be light white (because the actual cooking temperature of the fries is less than the standard cooking temperature), and the fries should be golden yellow. Therefore, in the input signals of the third group of learning samples, the cooking parameters are 200g of chicken, the cooking temperature is 180 ℃ and the cooking time is 5min, the dish images are light white, the dish varieties are fried chicken chops, and the output signals are the cooking effect reaching standards; in the input signals of the fourth group of learning samples, the cooking parameters are 200g of potatoes, the cooking temperature is 180 ℃ and the cooking time is 5min, the dish images are golden yellow, the dish types are French fries, and the output signals are the cooking effect reaching the standard.
Since the cooking effect of the third intelligent cooking device is not up to standard (the heating effect is too high), and the third intelligent cooking device fries 250g chicken and 250g potato for 5 minutes at a cooking temperature of 200 ℃, respectively, the fries in the dish image may be golden yellow (the chicken amount is larger than the standard dish amount, if the standard of the fries should be light white, but the heating effect of the third intelligent cooking device is too high, i.e. the actual cooking temperature is higher than 200 ℃, and thus may be golden yellow), and the fries may be dark brown (the potato amount is larger than the standard dish amount, and the cooking temperature of the fries is higher than the standard cooking temperature, if the standard of the fries should be golden yellow, but the heating effect of the third intelligent cooking device is too high, i.e. the actual cooking temperature is higher than 200 ℃, and thus may be dark brown). Therefore, in the input signals of the fifth group of learning samples, the cooking parameters are 250g of chicken, the cooking temperature is 200 ℃ and the cooking time is 5min, the dish images are golden yellow, the dish types are fried chicken chops, and the output signals are the cooking effect which does not reach the standard; in the input signals of the sixth group of learning samples, the cooking parameters are 250g of potatoes, the cooking temperature is 200 ℃ and the cooking time is 5min, the dish images are in dark brown, the dish varieties are fried chicken chops, and the output signals are the cooking effect which does not reach the standard.
Since the cooking effect of the fourth intelligent cooking apparatus is also not up to standard (the heating effect is too low), and the fourth intelligent cooking apparatus fries 200g chicken and 200g potato for 8min at a cooking temperature of 200 ℃, respectively, the fries in the dish image may be golden yellow (the actual cooking time period of the fries is longer than the standard cooking time period, if the actual cooking time period of the fries should be dark brown according to the standard of the fries, but the heating effect of the fourth intelligent cooking apparatus is too low, i.e., the actual cooking temperature is lower than 200 ℃, and thus may be golden), and the fries may be dark brown (even though the heating effect of the fourth intelligent cooking apparatus is too low, i.e., the actual cooking temperature of the fries is lower than 200 ℃, but the actual cooking time period of the fries is longer than the standard cooking time period, and thus should be dark brown). Therefore, in the input signals of the seventh group of learning samples, the cooking parameters are 200g of chicken, the cooking temperature is 200 ℃ and the cooking time is 8min, the dish images are golden yellow, the dish types are fried chicken chops, and the output signals are the cooking effect which does not reach the standard; in the input signals of the eighth group of learning samples, the cooking parameters are 200g of potatoes, the cooking temperature is 200 ℃ and the cooking time is 8min, the dish images are in a dark brown color, the dish varieties are French fries, and the output signals are that the cooking effect does not reach the standard.
After each cooking process is executed with the sample obtaining step to obtain a plurality of groups of learning samples, the plurality of groups of learning samples are adopted to carry out cooking effect checking training on the artificial neural network until the artificial neural network has the capability of checking whether the cooking effect of the intelligent cooking equipment reaches the standard according to the cooking parameters, the dish images and the dish types, so that the cooking effect checking method of the intelligent cooking equipment can be realized by utilizing the artificial neural network, and the cooking effect checking method is described in detail as follows a, b, c, d:
a. acquiring cooking parameters of the intelligent cooking equipment in a cooking process, wherein the cooking parameters are that after the intelligent cooking equipment executes a cooking starting program for cooking, the cooking temperature acquired from the cooking starting program is 200 ℃, the cooking duration is 5min and the quantity of dishes is 200g;
b. shooting the cooked dishes to obtain dish images capable of reflecting the cooking degree of the dishes, and recognizing that the dishes are golden yellow from the dish images;
c. identifying the dish shape as long according to the dish image, thereby identifying the dish type as french fries;
d. inputting the cooking parameters, the dish images and the dish variety types into a trained artificial neural network, wherein the artificial neural network is obtained after the training method is executed, and then checking whether the cooking effect of the intelligent cooking equipment reaches the standard or not according to the dish variety, the cooking parameters and the dish images by the trained artificial neural network. The standard cooking parameters of the French fries are 180 ℃ and the cooking time is 5min and 200g of potatoes, and in the actual cooking process, the cooking parameters are 200 ℃ and the cooking time is 5min and 200g of potatoes, so that the deep-black French fries are obtained according to the standard of the French fries, but the finally obtained French fries are golden yellow in practice, namely, cooking according to the too high cooking temperature cannot cause the French fries to become deep black, which means that the heating effect of the intelligent cooking device is too low, and therefore, the cooking effect of the intelligent cooking device is verified to be not up to standard.
