The embodiments described below by referring to the drawings are exemplary only for explaining the present invention and are not to be construed as limiting the present invention.
The present application discloses a refrigerator operation mode control method according to an embodiment, and although the present application provides the method operation steps described in the following embodiment or flowcharts 1 and 2, the method is based on conventional or non-creative labor, and there is no logically necessary causal relation in the steps, the execution order of which is not limited to the execution order provided in the embodiment of the present application. As shown in fig. 1, an embodiment of the present invention provides a method for controlling an operation mode of a refrigerator, the method includes the following steps, and the method and each step are described below:
s1, acquiring parameter data of a current refrigerator in operation and uploading the parameter data to a cloud server to obtain an average door opening time interval and a current door opening time interval;
in daily life, after the refrigerator is powered on and starts to run, the main control board of the refrigerator can record parameter data when the refrigerator runs currently, for example, the main control board can record parameter information such as the door opening times of the refrigerator in unit time and all door opening times continuously collected through the door opening sensor and upload the parameter information to the cloud server. And the cloud server calculates according to the received parameter information to obtain the average door opening time interval and the current door opening time interval in the unit time of the current refrigerator.
Specifically, it is assumed that the door opening times in the current refrigerator d days are continuously collected to be n, and the door opening times of two adjacent times are t respectively 1 And t 2 The first time is at time interval delta t 1 ＝t 2 -t 1 The current opening time interval is the difference between the current opening time and the last opening time of the refrigerator, and is recorded as delta t now . The ratio of the sum of all adjacent opening time intervals delta t in the opening times n of the refrigerator to the n-1 opening times is used for obtaining the average opening time interval which is recorded asThe average door opening timeThe separation can be calculated by formula (1).
S2, constructing a seasonal pairwise comparison matrix to obtain a seasonal weight vector;
it is known that the temperatures in different seasons are different, and this directly affects the number of times the refrigerator is opened; in winter, the temperature is low, people put food materials in a kitchen or a windowsill for a period of time, the food materials cannot be degraded immediately, so that people can put the food materials on the kitchen or the windowsill in winter instead of selectively putting the food materials in a refrigerator for refrigeration or freezing, the door opening times of the refrigerator are reduced, and the time interval for opening the door is increased; in summer, the temperature in most areas of China generally exceeds 25 ℃, so that if the food is not put in a refrigerator, the deterioration and decay speed of the food can be greatly increased; in addition, people in summer like iced beverages, ice cream, etc., which also greatly increases the frequency of using the refrigerator in summer, and thus the time interval for opening the door of the refrigerator is greatly reduced.
We target a decrease in the door opening time interval or an increase in the number of refrigerator doors, a seasonal pairwise comparison matrix Z may be constructed, specifically, assuming that the seasonal pairwise comparison matrix Z may be constructed by formula (2).
Wherein z is ij Indicating the importance of the ith factor relative to the jth factor, a larger value indicates that one factor is more important than another factor and vice versa; and i is more than or equal to 1 and j is more than or equal to 4, and the four seasonal factors are spring, summer, autumn and winter respectively. Say z 24 Indicating what is important in summer versus winter for the goal of reduced open time interval, and, in addition, z 42 Is z 24 Is the inverse of (c).
After the paired comparison matrix is constructed, the maximum characteristic root lambda of the matrix can be obtained max The corresponding specialThe eigenvector W, which can be expressed by formula (3).
W＝[w 1 ,w 2 ,w 3 ,w 4 ] (3)
Normalizing the feature vector W to obtain a normalized feature vector W n o rm The normalized feature vector can be expressed by formula (4).
W norm ＝[w norm,1 ,w norm,2 ,w norm,3 ,w norm,4 ] (4)
Wherein,
we define a normalized feature vector W norm The seasonal weight vector Φ may be represented by equation (6).
Φ＝[φ 1 ,φ 2 ,φ 3 ,φ 4 ]＝[w norm,1 ,w norm,2 ,w norm,3 ,w norm,4 ] (6)
Wherein,the season weights in spring, summer, autumn and winter are respectively.
S3, acquiring the food volume in the current refrigerator, the rated volume of the refrigerator and the storage state of the food volume, and uploading the food volume to a cloud server;
rated volume V of current refrigerator fridge Is easy to obtain, and the infrared sensor installed in the refrigerator cabin can detect the shape and size of the food stored in the refrigerator, thereby obtaining the volume V of the food in the refrigerator cabin food . The food volume storage state of the refrigerator can be obtained according to the rated volume of the refrigerator and the stored food volume. Specifically, let us assume that if V food <1/3V fridge The food materials put in the refrigerator are in a small quantity state; if 1/3V fridge ≤V food <7/10V fridge The ground food materials put in the refrigerator are in a general state at present; if V food ≥7/10V fridge The ground food material put in the refrigerator is in a saturated state at present. And uploading the acquired information to a cloud server for storage, so that a basis is provided for the subsequent judgment of refrigerator mode setting.
S4, acquiring the total running time, the running time and the residual running time of the current refrigerator mode and the refrigerator mode definition, and uploading the cloud server;
the timer on the main control board of the refrigerator can be used for recording the total running time T of the current refrigerator mode r Run time T d And remaining run time T l And the recorded information is uploaded to a cloud server, so that the basis is provided for the dynamic setting of the subsequent refrigerator mode. The total operation time refers to the time required from the setting to the end of the operation of the refrigerator mode; the operated time refers to the time from the setting to the time when the refrigerator mode has been operated; the residual operation time refers to the difference between the total operation time and the operated time in the current mode of the refrigerator.
S5, dynamically setting a refrigerator mode according to information such as the current opening time interval of the refrigerator, the average opening time interval of the refrigerator, the food volume storage state and the like;
through the refrigerator parameters and the mode definition, the cloud server can calculate and obtain the average door opening time interval, the seasonal weight vector and the food volume storage state of the current refrigerator according to the acquired information. And dynamically setting the current refrigerator mode according to the information. The refrigerator modes comprise an intelligent mode, a quick cooling mode, a quick freezing mode and a holiday mode, the names are just codes, and the names can be different in different models, for example, the holiday mode calls out a line mode on some refrigerators, so the refrigerator modes are not limited to the modes, and functions with similar modes are included in the scope of the invention.

In one embodiment, taking a refrigerating chamber of a refrigerator as an example, specifically, assuming that 11 door openings are total in three days before the last refrigerating chamber is opened and the total duration of the door opening time interval is 40 hours, the average door opening time interval is 4 hours, if the seasonal pairwise comparison matrix constructed by us is as follows:
