Referring to fig. 1 and 2, in particular, the method for controlling the temperature of the cold storage 10 includes the following steps:

step S100: acquiring the temperature distribution in the storage chamber 100 of the refrigerator 10;

step S200: acquiring the layout characteristics of the refrigerating objects in the storage chamber 100 of the refrigeration house 10;

step S300: and controlling the refrigerating capacity of the refrigerating elements 210 arranged at different positions in the refrigeration house 10 according to the temperature distribution and the layout characteristics.

In the method for controlling the temperature of the refrigerator 10, the cooling target to be stored is placed in the storage chamber 100 of the refrigerator, and the temperature detection module 300 is activated to collect the temperature in the storage chamber 100, so as to obtain the temperature distribution in the storage chamber 100. The collection assembly is further started, and the layout characteristics in the storage room 100 under the refrigeration object are judged through the collection assembly. According to the temperature distribution reaches layout characteristic, the refrigerating capacity of the refrigerating piece 210 arranged at different positions in the refrigeration house 10 is controlled, so that the temperature control of the refrigeration house 10 is more intelligent, the waste of electric energy is avoided, and the refrigeration of a refrigerating object is prevented from being influenced due to overhigh or overlow refrigerating temperature.

In one embodiment, the step S100 includes:

step S110: acquiring temperature values of different positions of the storage chamber in the storage chamber 100 of the refrigeration house;

step S120: and obtaining the temperature distribution according to the temperature value.

Specifically, the temperature of different positions in the storage chamber 100 is detected by the temperature detection assembly 300, so that the temperature distribution of the storage chamber 100 can be more accurately judged, and the accuracy of controlling the refrigeration parts 210 according to the temperature distribution is further improved.

Further, acquiring temperature values of a plurality of positions on the inner wall of the storage chamber 100 and temperature values of a plurality of positions of the inner space of the storage chamber 100; and obtaining the temperature distribution according to the temperature value. By acquiring the temperatures of the inner wall of the storage chamber 100 and the inner space of the storage chamber 100, the temperature of the storage chamber 100 can be more accurately determined.

step S220: the layout characteristics of the cooling objects in the storage room 100 are obtained according to the distance.

Since the cooling objects are stacked in different conditions in the storage compartment 100, the size and shape of the space occupied by the stacked cooling objects will affect the temperature distribution inside the storage compartment 100. If a single refrigeration mode is adopted, serious energy waste can be caused. In addition, the local temperature may not reach the refrigeration condition of the refrigeration object, and the refrigeration object may deteriorate and be damaged due to the local temperature being too low or too high, which may affect the storage stability of the refrigeration storage 10. By acquiring the distance between the refrigerating object and the inner wall of the storage chamber 100, the layout characteristics of the refrigerating object are obtained, thereby facilitating judgment of the stacking condition of the refrigerating object. When the refrigeration piece 210 is controlled, the refrigeration piece 210 can be controlled according to the layout characteristics of the refrigeration objects, so that the positions where the refrigeration objects are not distributed or the positions where the refrigeration objects are distributed less are not distributed, the refrigeration capacity of the corresponding refrigeration piece 210 is reduced, the purpose of energy conservation can be effectively achieved, and the waste of electric energy is avoided.

Or, when the number of the objects to be cooled is small and the objects to be cooled are uniformly distributed, the cooling members 210 are only arranged on the side walls of the storage chamber 100 to be opened, so that the cooling height of the cooling members 210 is reduced, and the cooling efficiency is effectively improved.

In one embodiment, after a certain time, the step S200 is repeated, so as to conveniently determine the layout condition of the refrigeration objects in the storage chamber 100 at intervals of a certain time, and further determine the stacking condition of the refrigeration objects, thereby improving the safety of the use of the refrigeration storage 10. Meanwhile, the stacking condition of the refrigerating objects can be judged at regular time, and the refrigerating capacity of the refrigerating element 210 can be controlled according to the stacking change of the refrigerating objects. Wherein the certain time can be 10s-5min, and can also be in other time ranges.

In other embodiments, the step S200 may be: acquiring image information of a cooling object in the storage chamber 100; and obtaining the layout characteristics of the refrigeration object according to the image information. It is sufficient if the layout of the cooling target in the storage room 100 can be obtained.

Referring to fig. 1 to fig. 3, in an embodiment, after the step S200, the method further includes:

step S230: and if the layout characteristics of the obtained refrigeration objects in the storage room 100 are changed, giving a fault alarm. When the layout characteristics of the obtained refrigeration objects in the storage chamber 100 change, the abnormal conditions in the storage chamber 100 are proved, the alarm is realized through the alarm, so that the personnel can check and eliminate the faults in time, and the use safety of the refrigeration house 10 is improved. For example, when the cooling object in the storage room 100 collapses, it may be detected that the layout characteristics of the cooling object in the storage room 100 change, or when it is detected that the cooling object moves in the storage room 100, a person may stay in the storage room 100.

In an embodiment, before the step S300, the method further includes:

step S400: acquiring a standard refrigerating temperature of the refrigerating object;

specifically, the standard cooling temperature is acquired according to the type or name of the cooling object. In general, different refrigeration objects have different refrigeration temperature requirements, for example, the suitable storage temperature of fruits and vegetables is-2 ℃ to 10 ℃, and the refrigeration temperature of frozen meat generally needs to be stored at a low temperature of-18 ℃. Furthermore, before the refrigeration, it is necessary to determine the appropriate refrigeration temperature for the refrigeration target by the type of the refrigeration target.

After the cooling object is stacked in the storage chamber 100, the temperature of the cooling object itself affects the temperature distribution of the storage chamber 100, so that the temperature distribution of the storage chamber 100 is unstable. When the average temperature value in the storage chamber 100 is greater than the standard refrigerating temperature, each refrigerating part is controlled to refrigerate the interior of the storage chamber, so that the average temperature value of the refrigerated interior temperature of the storage chamber is less than or equal to the standard refrigerating temperature, and the effect of stabilizing the temperature distribution in the storage chamber 100 can be achieved.

In this embodiment, the average temperature value after the interior of the storage compartment is cooled is equal to the standard cooling temperature. When the standard refrigeration temperature is within a temperature interval range, the average temperature value after refrigeration can be within the temperature interval of the standard refrigeration temperature; when the standard refrigerating temperature is a fixed temperature value, the average temperature value after refrigeration can be equal to the standard refrigerating temperature.

Specifically, the step S410 includes:

step S412: comparing the temperature difference between the current average temperature value inside the storage chamber and the standard refrigerating temperature to determine the total refrigerating capacity of all refrigerating pieces; wherein the larger the temperature difference, the larger the total cooling capacity;

step S414: and starting a standard refrigeration mode to finish the total refrigeration capacity.

Further, after the standard cooling mode is started to complete the total cooling capacity, the step S100 is repeated.

According to the method, the total refrigerating capacity of all the refrigerating pieces 210 can be conveniently and effectively judged by comparing the temperature difference between the average temperature value and the standard refrigerating temperature, and the standard refrigerating mode is started to finish the total refrigerating capacity. The temperature distribution of the storage chamber 100 can be effectively stabilized by completing the total refrigerating capacity through the standard refrigerating mode, so that the stability of obtaining the temperature distribution in the subsequent steps is improved, and the stability of accurately controlling the refrigerating element 210 is improved.

In this embodiment, the step S414 may be: the standard cooling mode is started to perform cooling so that an average temperature value of the temperature values at the plurality of positions in the storage chamber 100 is identical to the standard cooling temperature, and thus it can be considered that the total cooling capacity is completed. In an embodiment, when the standard refrigeration temperature is a fixed value, the average temperature value is equal to the standard refrigeration temperature, or when the temperature difference between the standard refrigeration temperature and the standard refrigeration temperature may be within a certain range, the total refrigeration capacity may be considered to be completed, for example, the temperature difference between the average temperature value and the standard refrigeration temperature may be 0 to 3 ℃. Of course, the temperature difference may be in other ranges depending on the type of the cooling object. In another embodiment, the standard cooling temperature may be a temperature range, and when the average temperature is within the temperature range, the total cooling capacity may be considered to be completed.

In another embodiment, the step S414 may be: the total cooling power of all the cooling elements 210 can be determined according to the temperature difference between the average temperature value and the standard cooling temperature, and the total cooling capacity of the cooling elements 210 can be achieved according to the total cooling power. Wherein the larger the temperature difference, the larger the total cooling power.

In other embodiments, the step S414 may be: the refrigerating time for the standard refrigerating mode to finish the total refrigerating capacity can be judged according to the temperature difference between the average temperature value and the standard refrigerating temperature. When the cooling time is completed, the total cooling capacity is considered to be completed. The refrigeration time may be a time range, and the time range may be a refrigeration time range in which the average temperature value and the standard refrigeration temperature correspond to each other within a certain temperature difference range.

In this embodiment, the standard refrigeration mode is that all the refrigeration pieces 210 in the refrigeration house 10 refrigerate at the same time with the standard refrigeration capacity, and the sum of the standard refrigeration capacities of the different refrigeration pieces 210 is the total refrigeration capacity. In this embodiment, the cooling member 210 completes the total cooling capacity with the maximum cooling capacity, so as to complete the total cooling capacity with the shortest time, thereby improving the cooling efficiency. Specifically, the cooling members 210 are dampers, and all the dampers of the freezer 10 are in a fully open state to perform cooling.

In an embodiment, before the step S100, the method further includes:

step S130: acquiring a closing signal of the warehouse door 120;

step S140: and if the acquisition of the closing signal of the bin gate 120 is interrupted or the closing signal of the bin gate 120 is not acquired, giving a fault alarm.

If the acquired closing signal of the storage door 120 is interrupted or the closing signal of the storage door 120 is not acquired, it can be determined that the storage door 120 is not closed, which may affect the stability of the temperature in the storage chamber 100, and further cause inaccurate acquired temperature distribution and affect the control of the refrigeration element 210. When the alarm occurs, the alarm is convenient for reminding personnel to eliminate the fault.

In an embodiment, after the step S140, the method further includes:

step S150: and starting the standard refrigeration mode for refrigeration.

In one embodiment, the step S330 includes:

step S332: if the refrigeration objects are not distributed in the area, the refrigeration piece 210 corresponding to the area is controlled to close or reduce the refrigeration capacity. If the area is not provided with the refrigeration objects, the area does not need to be refrigerated, the refrigerating capacity of the refrigerating element 210 at the corresponding position can be correspondingly reduced, or the refrigerating element 210 at the corresponding position is closed, so that the energy-saving effect is further realized.

In another embodiment, the step S330 includes:

step S334: if the cooling objects are distributed in the area, the cooling capacity of the cooling member 210 corresponding to the area at the control position is increased. Because the temperature value in this area is greater than standard refrigeration temperature, and this area has the refrigeration object, and then need further increase the refrigerating output to make this area temperature reach standard refrigeration temperature, guarantee the cold-stored effect of refrigeration object.

In other embodiments, the step S300 includes:

step S340: according to the temperature distribution, determining a region corresponding to a temperature value smaller than the standard refrigerating temperature in the storage room;

step S342: if the refrigeration objects are not distributed in the area, the refrigeration piece 210 corresponding to the area is controlled to close or reduce the refrigeration capacity. If the area is not provided with the refrigeration objects, the area does not need to be refrigerated, the refrigerating capacity of the refrigerating element 210 at the corresponding position can be correspondingly reduced, or the refrigerating element 210 at the corresponding position is closed, so that the energy-saving effect is further realized.

In another embodiment, step S344: if the refrigeration object exists in the area, the refrigeration piece corresponding to the area is controlled to reduce the refrigeration amount, so that the temperature value of the area is equal to the standard refrigeration temperature, and the refrigeration stability of the refrigeration object can be effectively improved.

According to the method, the temperature distribution can accurately reflect the temperature conditions of different positions in the storage chamber 100, so that the refrigerating capacity of the refrigerating piece at the corresponding position is adjusted according to the layout condition of the refrigerating object, the refrigerating stability of the refrigerating object can be effectively improved, and the purpose of energy conservation is achieved.
