[0034] In this embodiment, a refrigeration control method for a cold storage running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0035] Figure 2 FIG. 1 is a flow chart of a refrigeration control method for a cold storage according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0036] Step S201, obtaining the distance between each air cooler of the cold storage, and determining a plurality of refrigeration units according to the distance, wherein the refrigeration unit includes at least two of the air coolers and the distance between any two of the air coolers of the refrigeration unit is less than a predetermined distance;

[0037] Step S202, when there are goods in the cold storage, control each of the refrigeration units to start one of the air coolers.

[0038] In the refrigeration control method of the above-mentioned cold storage, air coolers whose distance is less than a predetermined distance are formed into a refrigeration group, thereby dividing multiple air coolers in the cold storage into multiple refrigeration groups. When there are goods in the cold storage, only one air cooler in each refrigeration group needs to be turned on to ensure that the temperature of the cold storage is uniform while ensuring that there is at least one turned-on air cooler near any goods to achieve local refrigeration without considering the shape of the cold storage, thereby solving the problem of poor local refrigeration effect of special-shaped cold storage in the prior art.

[0039] In order to ensure the stability of the cold storage temperature, in an optional implementation, Figure 3 As shown, after controlling each of the above refrigeration units to start one of the above air coolers, the above method further includes:

[0040] Step S301, when the air cooler turned on in the target refrigeration unit fails, controlling the air cooler without failure in the target refrigeration unit to turn on, the target refrigeration unit being any one of the refrigeration units.

[0041] In the above implementation, taking four air coolers installed in the warehouse as an example, a refrigeration unit includes two air coolers. If one unit of a refrigeration unit is turned on, the remaining one is a standby unit. According to the scheduling of the centralized controller, the standby unit is activated after one of the turned-on air coolers is shut down to ensure the stability of the cold storage temperature.

[0042] In order to achieve local refrigeration near the cargo, in an optional implementation, as Figure 4 As shown, the above step S202 includes:

[0043] Step S2021, when the goods are in the cold storage, controlling each of the air coolers to acquire a signal sent by the NFC tag of the goods to obtain a plurality of first positioning signals;

[0044] Step S2022, locating the distance between the goods and each of the air coolers according to the plurality of positioning signals to obtain a plurality of first cooling distances;

[0045] Step S2023, controlling each of the refrigeration units to start one of the air coolers, so that the air cooler with the smallest refrigeration distance is turned on.

[0046] In the above implementation, cargo positioning needs to be completed before intelligent grouping. An NFC tag is added to the plug board where the cargo is stored or an NFC tag is attached to the stored cargo. An antenna board is installed on the air cooler in the warehouse to detect the tag signal, so that the tag distance is determined according to the signal detected by the antenna, and the distance between the cargo and the air cooler is determined, and multiple first cooling distances can be obtained. Each of the above refrigeration units selects one air cooler to turn on, and ensures that the air cooler with the smallest cooling distance is turned on, so as to achieve local cooling near the cargo and ensure faster cooling around the cargo.

[0047] In order to better achieve local cooling, in an optional implementation, as Figure 5 As shown, after controlling each of the above refrigeration units to start one of the above air coolers, the above method further includes:

[0048] Step S401, when new goods are stored in the cold storage, the turned-on air cooler is determined as the first air cooler;

[0049] Step S402, controlling each of the above-mentioned air coolers to obtain the signal sent by the NFC tag of the above-mentioned new goods, and obtaining multiple second positioning signals;

[0050] Step S403, locating the distance between the new goods and each of the cooling fans according to the plurality of positioning signals, and obtaining a plurality of second cooling distances;

[0051] Step S404, determining the above-mentioned cooling air machines other than the above-mentioned first cooling air machine whose cooling distance is less than the second predetermined distance as the second cooling air machines, controlling all the above-mentioned second cooling air machines to be turned on for a first predetermined time and then turned off, and keeping the above-mentioned first cooling air machines turned on.

[0052] In the above implementation, an NFC tag is added to the plug board where the new goods are stored or an NFC tag is attached to the stored new goods. An antenna board is installed on the air cooler in the warehouse to detect the tag signal, so that the tag distance is determined according to the signal detected by the antenna, and the distance between the new goods and the air cooler is determined, and multiple second cooling distances can be obtained. The air coolers other than the first air cooler whose cooling distance is less than the second predetermined distance are determined as second air coolers, and all the second air coolers are controlled to be turned on for the first predetermined time and then turned off, that is, more than one air cooler is turned on near the new goods to achieve rapid cooling near the new goods.

[0053] In order to ensure the refrigeration effect of the goods, in an optional implementation, Figure 6As shown, after controlling each of the above refrigeration units to start one of the above air coolers, the above method further includes:

[0054] Step S501, a closing step, in which, when the number of the air coolers allowed to run is less than the number of the refrigeration units, the air cooler with the largest refrigeration distance is controlled to be closed;

[0055] Step S502, repeating the above-mentioned closing step at least once until the number of the above-mentioned cooling fans turned on is equal to the number of the above-mentioned cooling fans allowed to run.

[0056] In the above implementation, when the number of the above-mentioned air coolers allowed to run is less than the number of the above-mentioned refrigeration units, it cannot be guaranteed that each refrigeration unit will turn on an air cooler, and the air coolers farther away from the goods are shut down first to avoid temperature rise near the goods.

[0057] In order to increase the service life of the air cooler, in an optional implementation, Figure 7 As shown, when there are goods in the cold storage, after controlling each of the refrigeration units to start one of the air coolers, the method further includes:

[0058] Step S601, determining the currently turned-on air cooler as the first air cooler;

[0059] Step S602, when the running time of the first cooling air machine is greater than or equal to the second predetermined time, controlling all the first cooling air machines to be turned off, and controlling the first cooling air machines other than the first cooling air machine to be turned on, so that at least one cooling air machine is turned on in each of the refrigeration units;

[0060] Step S603, determining the currently turned-on air cooler as the third air cooler;

[0061] Step S604, controlling the first cooling air machine and the third cooling air machine to operate alternately at intervals of the second predetermined time period.

[0062] In the above embodiment, the turned-on air cooler of each refrigeration unit is used as the first air cooler, and the backup air cooler of the first air cooler is used as the third air cooler. The first air cooler and the third air cooler are controlled to operate alternately at intervals of the second predetermined time period to avoid uneven operation time of the air coolers, which may lead to problems such as short life of the air coolers or easy failure.

[0063] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the refrigeration control method of the cold storage of the present application will be described in detail below in combination with specific embodiments.

[0064] This embodiment relates to a specific refrigeration control method for a cold storage, such as Figure 8 As shown, the following steps are included:

[0065] Two air coolers need to be turned on. If they are not grouped, the group controller will select two air coolers from the four air coolers according to the scheduling rules. The following situations will occur: Situation 1: Turn on units 1 and 2. At this time, units 3 and 4 are standby units and are not turned on. Units 1 and 2 are closer to the goods and the temperature is slower, wasting cooling resources. Situation 2: Turn on units 1 and 4. Although one of the units is closer to the location where the goods are stored, when unit 4 fails, the dispatcher will select unit 2 from units 2 and 3 to turn on the air outlet. The air outlet will be far away from the storage location of the goods, and local cooling cannot be achieved. Turning on units 1 and 3 or units 2 and 3 or units 1 and 4 is similar to scenario 2. If the above situation occurs, there is a certain distance from the actual stored goods, and the goods cannot be cooled quickly. Only when the temperature of the entire warehouse approaches the target temperature can the goods have a better cooling effect, which takes a long time and consumes electricity. If the following measures are taken Figure 8 The control method shown in the figure determines the closest distance to the goods according to the distance between the cooling fan and the goods label collected by the antenna board. Fig. 9 The air coolers shown in the figure therefore divide air coolers 3 and 4 into group 1, and air coolers 1 and 2 into group 2. In this way, at least one air cooler near the goods can be kept turned on, thereby achieving the effect of rapid cooling and uniform warehouse temperature.

[0066] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

Each of the above refrigeration units selects one air cooler to turn on, and ensures that the air cooler with the smallest cooling distance is turned on, so as to achieve local cooling near the cargo and ensure faster cooling around the cargo.

[0089] The repeating unit is used to repeat the above-mentioned closing step at least once until the number of the above-mentioned cold air fans turned on is equal to the number of the above-mentioned cold air fans allowed to run.

[0090] In the above implementation, when the number of the above-mentioned air coolers allowed to run is less than the number of the above-mentioned refrigeration units, it cannot be guaranteed that each refrigeration unit will turn on an air cooler, and the air coolers farther away from the goods are shut down first to avoid temperature rise near the goods.
