A seventh embodiment of the present invention is based on the above embodiments, and an application example of the present invention is described with reference to fig. 7 to 10 by taking an intelligent refrigerator to store food as an example.
The networking situation of the intelligent home system of the application example is shown in fig. 7, and an intelligent refrigerator, a mobile phone, a computer and an intelligent terminal are all connected to an intelligent router or a remote server. The intelligent refrigerator sends the collected food data to the intelligent router or the remote server, the intelligent router or the remote server processes the food data and then sends the food data to the intelligent refrigerator, the mobile phone, the computer and the intelligent terminal, and the terminals execute instructions of the intelligent router or the remote server.
1) As shown in fig. 8, a processing flow of the smart home system when the user puts food into the smart refrigerator is as follows:
when a user puts various foods, a camera in the refrigerator takes a picture of each food and determines coordinates (similar to the position information of the articles of the fourth embodiment) of the food in the room, and the coordinates are transmitted to the intelligent router or the remote server through wireless transmission;
the intelligent router or the remote server compares and identifies the shot food photos with food samples in a database of the intelligent router or the remote server, identifies which food is, extracts colors in the shot food photos to be matched with color grade samples of the food stored in the database when the food is identified, and obtains corresponding storage temperatures of the food because the colors of each grade of the food correspond to the most appropriate storage temperature when the food is matched with the colors of a certain grade; in addition, under the determined color grade, the food is about to deteriorate or is deteriorated by comparing the color uniformity degree of the food.
Then, whether the food should be placed in the refrigerating chamber, the temperature changing chamber or the freezing chamber is judged according to the determined preservation temperature, and when the food should be placed in which chamber is determined, the intelligent refrigerator is informed of the chamber to which the food should be placed. For example: the food is tomatoes and the food is determined to be put into the fresh-keeping room, the intelligent refrigerator can send a voice broadcast' please put tomatoes into the fresh-keeping room! ".
And making a label for the food stored in the intelligent router or the remote server at the intelligent router or the remote server, wherein the label comprises the color grade of the food, the deterioration degree, the temperature range stored in the refrigerator, the starting time of the storage, and the room in which the food is stored and the coordinates of the storage. The labeled holding temperatures of the food labels are then compared to the previously labeled holding temperatures of each of the food labels stored in the chamber to find the minimum value of the holding temperatures. After finding this minimum, the temperature of the refrigerator XXX compartment is set to this value.
The intelligent router or the remote server searches all food labels to find out foods which are going to go bad or go bad and informs a user of the foods going bad through a refrigerator, a mobile phone, a terminal and a computer. The whole process flow is as follows:
2) as shown in fig. 9, the processing flow of the smart home system when the user takes out food from the smart refrigerator is as follows:
when a user takes out a certain kind of food, the camera in the intelligent refrigerator takes pictures of the food and determines the coordinates of the food in the chamber, and uploads the coordinates to the intelligent router or the remote server, the intelligent router or the server determines the grade of the color of the food by comparing the food color grade samples in the database, determines whether the food is going to go bad or goes bad according to whether the abnormal color distribution of the food is even and reasonable under the color grade, and can also determine the deterioration degree of the food (due to different storage time of the food at different temperatures) by calculating the time for putting the food in and the temperature of the chamber. If the food taken out by the user is going to go bad or has gone bad, the intelligent router or server informs the intelligent refrigerator that the XXX food is going to go bad or has gone bad.
And the intelligent router or the remote server determines the food label by comparing the coordinates of the food with the coordinates of all the food labels stored on the intelligent router or the remote server, and rejects the food label. And then sequentially comparing the temperatures recorded by the rest food labels and required to be stored in the food, finding out the minimum value, and resetting the XXX chamber temperature of the intelligent refrigerator as the value.
3) As shown in fig. 10, the processing flow of the smart home system periodically adjusting the temperature of the smart refrigerator is as follows:
the intelligent router and the remote server require the intelligent refrigerator to recalculate the current temperature which should be set for each room at regular intervals, and the intelligent router or the server sequentially sends the coordinates of each food in the food label pool to the intelligent refrigerator. After the intelligent refrigerator receives the label coordinates of each food, the direction and the position of the camera are adjusted according to the coordinates, food photos on the position of the seat mark are shot, and the food photos are transmitted to the intelligent router or the remote server. The intelligent router or the remote server determines the grade of the color of the food by comparing the color grade samples of the food in the database, further determines the temperature at which the food is to be stored, determines whether the food is going to deteriorate or has deteriorated according to whether the abnormal color distribution of the food is uniform and reasonable under the color grade, and can also determine the deterioration degree of the food (due to different storage times of the food at different temperatures) by calculating the time for putting the food into the room and the temperature of the room. The preservation temperature recorded by the food label is updated, whether the food label is going to deteriorate or has deteriorated, and how long the food label is preserved.
If the food taken out by the user is going to go bad or has gone bad, the intelligent router or the remote server sends the XXX food to the intelligent refrigerator. The intelligent router or the remote server determines the temperature value for ensuring that each food can be normally stored as the temperature of the room by comparing the storage temperature recorded by each food label in each indoor label pool in sequence.
The scheme of the application example of the invention mainly solves three technical problems:
1. a temperature value which can ensure that each food can be stored for a longer time without deterioration and can save most electricity is searched for a plurality of different kinds of foods put into the intelligent refrigerator.
2. By differentiating different foods, the required holding temperature of the food is determined according to the color of the food at different periods. Therefore, the food fresh-keeping time can be effectively prolonged, and the electric quantity consumption of the refrigerator can be reduced.
3. Through the color of the food, the food deterioration degree can be distinguished, whether the food is deteriorated or not can be distinguished, and the user can be reminded in time.
In order to solve the above technical problems, in the embodiments of the present invention, when a user puts various foods, the refrigerator may process the foods put in the refrigerator according to the types of the foods and the colors of the foods, calculate a temperature required to be stored for each kind of food, and finally calculate a temperature that is most suitable for storing all foods and should be set by the refrigerator through a comprehensive algorithm.
When a user puts in or takes out a certain food, the refrigerator automatically recalculates an appropriate temperature according to the type and color of the remaining food and sets the temperature.
The food is stored for a period of time and changes, the previously set temperature is not suitable for the present time, so the color of the food is scanned once by the refrigerator at intervals, if the color of one or more foods changes, the temperature required by the type of the food is calculated by the refrigerator according to the type and the color grade of the food, and then the temperature required by other foods is integrated to calculate the temperature required by the preservation of all the foods in the refrigerator.
The food is different from the non-deteriorated color immediately after or after the deterioration, and the color of a certain portion is uneven, for example, the color is yellow immediately before the deterioration of banana, and the color is dark yellow immediately after the deterioration or after the deterioration. For example, after the tomatoes are spoiled, the spoiled mass of tomatoes is different from normal. When the refrigerator detects the color, the voice broadcasts that the bananas stored in the refrigerator are going to go bad and please eat as soon as possible or that the tomatoes stored in the refrigerator go bad.
According to the intelligent temperature control method and device for the refrigerator and the refrigerator, provided by the embodiment of the invention, the working temperature of the refrigerator can be automatically adjusted according to the condition of stored articles. The variety of the articles can be distinguished for a plurality of different types of articles placed in the refrigerator, and the storage temperature required by each article can be determined, so that the aim of effectively prolonging the freshness keeping time of the articles and reducing the power consumption of the refrigerator can be fulfilled. The invention can also determine the deterioration degree of the articles according to the colors of the articles and remind the user in time.
While the invention has been described in connection with specific embodiments thereof, it is to be understood that it is intended by the appended drawings and description that the invention may be embodied in other specific forms without departing from the spirit or scope of the invention.
