Example 1
Fig. 1 is a flowchart of a local temperature control method for a cold storage according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step S101, identifying the type of a target object in a refrigeration house;
step S102, monitoring the temperature changes of all air coolers in the cold storage, and determining the air cooler adjacent to the target article according to the temperature changes;
step S103, controlling an air cooler adjacent to the target object to start, and refrigerating according to a preset temperature; wherein, the corresponding relation between the type of the article and the preset temperature is preset.
When target articles are put in storage, the types and the placement areas of the articles are intelligently judged, and part of air coolers in a part of cold storages are reasonably started, so that on the premise of ensuring the storage effect of the articles, the resources such as electric energy are saved, and the article storage efficiency of a cold storage manager is improved.
In this embodiment, the target article is an article that has just been put in storage. Therefore, the type of the target object can be identified through the camera arranged at the entrance of the refrigeration house. For the classification of the type of the article, a setting may be made in advance, for example, the classification is: meat, seafood, vegetables, etc., and each type of item, which corresponds to a different suitable preset temperature, may have an optimum storage temperature (preset temperature) of meat set to-18 deg.c, a preset temperature of seafood set to-25 deg.c, vegetables set to 3 deg.c, etc.
Since the temperature of the surface of the article is higher than the temperature of the freezer immediately after the article enters the freezer from the outside, the temperature around the article changes after the article is placed. The temperature change of all the air coolers in the cold storage is monitored, and the air coolers close to the target object can be determined according to the temperature change. Specifically, a temperature sensor array is arranged on each air cooler, and the temperature change of each air cooler is monitored through the temperature sensor array arranged on each air cooler; and if the temperature change of one or more air coolers exceeds a preset threshold value and continuously changes within a preset time period, determining one or more air coolers as the air cooler adjacent to the target article. Based on this, can pinpoint the air-cooler that the target article is close to and place the position. Therefore, the operation of the air coolers close to the target article can be adjusted according to the requirement, the operation of all the air coolers in the cold storage is not required to be controlled, and the energy consumption is saved.
Under the condition that a plurality of air coolers are close to the target object, the air coolers close to the target object can be controlled to be started completely; or controlling any one of the air coolers adjacent to the target article to start. It should be noted that the air cooler adjacent to the target object is understood to be the air cooler closest to the target object. The air cooler adjacent to the target article may be controlled to operate at a preset temperature corresponding to the type of the target article. Based on this, the storage temperature near the target object can be adjusted quickly, and the temperature of the position where the target object is located in the refrigerator can be adjusted to the optimum storage temperature of the target object as soon as possible.
After the air cooler is controlled to be started, because the air cooler is the air cooler close to the target object, the air opening of the air cooler is not necessarily just aligned to the target object, and the refrigerating and cooling effects of the air cooler are also reduced. In order to ensure the refrigeration and cooling effects, the air port adjusting angle can be calculated according to a preset formula, and the included angle between the air cooler and the side wall of the refrigeration house where the air cooler is located is adjusted according to the air port adjusting angle, so that the air port of the air cooler is aligned to a target object. It should be noted that the included angle may be an acute angle or an obtuse angle, and with respect to the position of the target object, if the air cooler adjacent to the target object and the adjacent air cooler are both located on the same side of the target object, the included angle is an obtuse angle; if the air cooler adjacent to the target object and the adjacent air cooler are respectively positioned at two sides of the target object, the included angle is an acute angle.

In the rectangular coordinate system O-XY, A is the air cooler near the target object, and B is the adjacent air cooler located on the same side wall as the air cooler A. In a rectangular coordinate system O-XY, OG represents the width of the refrigeration house body 1, OA represents the distance from the air cooler A to the lower left corner of the refrigeration house body 1, AB represents the installation distance between the two air coolers, and the installation distances can be obtained through actual measurement and stored in advance. The P point of the O-XY rectangular coordinate system in FIG. 2 is the target object.
Specifically, the air port adjustment angle of the air cooler a can be calculated by the following preset formula:
the air inlet adjusting angle is alpha, the linear distance between the air cooler A and the target object P is a, the linear distance between the air cooler A and the adjacent air cooler B on the same side wall is c, and the linear distance between the adjacent air cooler B and the target object P is B.
For the calculation of the straight-line distance, the following formula can be used for calculation:
where v denotes the propagation velocity of radio waves in the air, and t denotes the time required from the transmission of a data request by a tag reader to the reception of data fed back by an electronic tag, where one tag reader may be provided on each air cooler, and an electronic tag may be provided on each article.
Similarly, the linear distance B between the adjacent air cooler B and the target article P can also be calculated by using the above formula. And to the linear distance c between air-cooler A and the adjacent air-cooler B, because the position of all air-coolers in the freezer is fixed, so the linear distance of two adjacent air-coolers can be accurate for the linear distance of the label reader on two adjacent air-coolers, can measure or set up in advance to save in advance. When the technical scheme of the invention is applied, the linear distance between the air cooler and the adjacent air cooler can be known through the serial number of the air cooler.
Based on this, can adjust the wind gap angle of air-cooler, make its wind gap aim at the target article to realize effective refrigeration, realize the quick adjustment to the temperature of target article.
After controlling the air cooler close to the target object to start and refrigerating according to the preset temperature, continuously monitoring the temperature of the target object; and if the temperature of the target object is not in the preset temperature range, controlling an air cooler adjacent to the target object to perform temperature compensation operation. The temperature of the target object can be monitored by a temperature sensor arranged on the target object, and can also be monitored by an infrared sensor.
If the temperature of the target object is higher than the highest value of the preset temperature range, the gear of a fan of an air cooler adjacent to the target object is increased until the temperature of the target object is in the preset temperature range; and if the temperature of the target object is lower than the lowest value of the preset temperature range, the gear of a fan of an air cooler adjacent to the target object is lowered until the temperature of the target object is within the preset temperature range. Based on the temperature control method, the temperature of the surface of the target object can be monitored in real time, and the operation of the air cooler adjacent to the target object can be adjusted accordingly, so that the temperature of the target object is kept at the optimal storage temperature.
To how to increase the fan gear of the air-cooler that the target article is close to, specifically: calculating the difference value of the temperature of the target object and the highest value of the preset temperature range; determining an adjusting value of the fan gear according to the difference value; and adjusting the gear of the fan of the air cooler according to the adjusting value. Similarly, for how to lower the fan gear of the air cooler adjacent to the target article, specifically: calculating the difference value between the temperature of the target object and the lowest value of the preset temperature range; determining an adjusting value of the fan gear according to the difference value; and adjusting the gear of the fan of the air cooler down according to the adjusting value. That is, the correspondence relationship between the difference value and the adjustment value of the gear position may be set in advance, for example, the larger the difference value, the larger the adjustment value of the gear position. Based on this, the temperature compensation of realization air-cooler that can be more accurate, thereby near the temperature of more efficient adjustment target article guarantees the best storage effect.

Fig. 4 is a flowchart of a multi-point temperature control strategy of a refrigerator according to an embodiment of the present invention, as shown in fig. 4, the flowchart includes the following steps:
in step S401, the camera identifies the type of the target item stored in the refrigerator. The camera can be installed at the entrance of the refrigeration house, and the target object refers to the object just stored in the refrigeration house.
And S402, setting the preset temperature of the air cooler according to the type of the target object.
Step S403, judging whether the temperature of the air cooler rises in the refrigerator or not; if yes, step S404 is executed, and if not, the process returns to step S403.
Specifically, the temperature change of the air cooler can be monitored through a temperature sensor array arranged on the air cooler.
Step S404, judging whether the temperature of the cooling fan continuously rises within a preset time. That is, whether the temperature change of the air-cooler exceeds a preset threshold value and continuously changes within a preset time period.
If yes, step S405 is executed, and if no, execution returns to step S403.
After the target object is stored in the refrigerator, since the temperature of the target object in the outside is higher than the temperature in the refrigerator, the temperature sensor array attached to the periphery of the target object detects a temperature increase when the target object passes through each air cooler. However, if the temperature of the target object is only temporarily increased, it indicates that the target object only passes through the air cooler and is not placed around the air cooler, and if the target object is placed in front of the air cooler, the temperature detected by the temperature sensor array of the air cooler is continuously increased. Therefore, it can be judged that the target item is placed in the vicinity of the cold air blower by the continuous rise in the ambient temperature of the cold air blower.

Step S408, judging whether the surface temperature of the target object exceeds the maximum value of a preset temperature range; if yes, step S409 is performed, and if no, step S410 is performed. Of course, the preset temperature range may also be a preset temperature threshold, and exceeding the temperature threshold indicates that the surface temperature of the target object is too high and needs to be cooled.
Step S409, cooling the target object, specifically, increasing the fan gear of the air cooler adjacent to the target object until the temperature of the target object is within the preset temperature range.
Step S410, the temperature of the target object needs to be raised, specifically, the gear of the fan of the air cooler adjacent to the target object is lowered until the temperature of the target object is within the preset temperature range.
In general, only one temperature sensor array of the air cooler can detect large changes of the ambient temperature. However, if the temperature sensor arrays of the two air coolers detect that the ambient temperature is rising at the same time, it is indicated that the target object is placed in the middle position of the junction of the two air coolers. Under the condition, the controller 9 can wake up two air coolers, and can wake up one air cooler close to the target object randomly according to actual conditions.
The above strategy of this embodiment detects the article type of storing the warehouse through the camera, sets up the preset temperature (still can set up the error value) of freezer automatically, has improved the efficiency that freezer administrator article were put in storage, can intelligent judgement article place the region simultaneously, rationally opens the cold wind unit in some freezers, has practiced thrift resources such as electric energy.
