Each first side panel 103 is provided with an electric air deflector 109 on both sides of its folding line, and a refrigeration device is provided on the inner side of one of the second side panels (not shown in the drawings).

[0026] For example, the types of the refrigerated stacked goods 111 can be, but are not limited to, ice cream packaged by small boxes, biological agents (such as insulin), and vaccines (such as the new crown vaccine), etc. It can be understood that there are gaps between each refrigerated stacked good 111 packaged by small boxes, which can be ventilated.

[0027] S202: subtracting the first distance value by a preset distance threshold to obtain a first distance difference, subtracting the second distance value by the preset distance threshold to obtain a second distance difference, and subtracting the third distance value by the preset distance threshold to obtain a third distance difference.

[0029] Exemplarily, the foldable angles corresponding to the first distance difference and the second distance difference can be found from the preset database according to a preset first mapping relationship, and the foldable angle corresponding to the third distance difference can be found from the preset database according to a preset second mapping relationship. It should be noted that the first to-be-trained network is a neural network.

[0030] wherein, Figure 2 is a cross-sectional view of the intelligent refrigerated container after folding, and the foldable angle can be the included angle between the two parts of the first side panel 103 after folding.

[0031] S204: determining the refrigeration temperature required by the refrigerated stacked goods 111 according to the type of the refrigerated stacked goods 111.

[0032] For example, the refrigeration temperature required by the refrigerated stacked goods 111 can be found from the preset database.

[0033] S205: inputting the type, weight, and refrigeration temperature of the refrigerated stacked goods 111 into the pre-trained operation parameter determination model to determine a plurality of sets of operation parameters of the intelligent refrigerated container for maintaining the refrigeration temperature at each position on the refrigerated stacked goods 111, each set of operation parameters including the refrigeration power of the refrigeration equipment, the air outlet speed and direction, and the angle between the extension direction of each electrically operated air deflector 109 to the inside of the box and the horizontal direction.

[0034] The operation parameter determination model is obtained by inputting a plurality of first training samples into a first to-be-trained network for training, each first training sample including a historical type, a historical weight and a historical refrigeration temperature of a historical refrigerated stacked cargo 111, and historical operation parameters of an intelligent refrigerated container for maintaining the historical refrigeration temperature at each position on the historical refrigerated stacked cargo 111.

[0039] In summary, the application provides a refrigerated container control method based on artificial intelligence, which can stack refrigerated stacked cargos 111 from the center of the refrigerated container to the periphery, and the refrigerated stacked cargos 111 need to maintain a certain distance from the inner wall of the refrigerated container to ensure the air flow passage inside. Further, the type and weight of the refrigerated stacked cargos 111 to be transported in the box body input by the user on the man-machine interaction panel 108 can be received, and the first distance value collected by the first distance sensor 105, the first distance value collected by the second distance sensor 106 and the third distance value collected by the third distance sensor 107 can be received. The first distance value is subtracted by the preset distance threshold value to obtain the first distance difference (i.e. the distance that one of the first side panels 103 can move towards the inside of the box body after reserving the air flow passage distance), the second distance value is subtracted by the preset distance threshold value to obtain the second distance difference (i.e. the distance that the other first side panel 103 can move towards the inside of the box body after reserving the air flow passage distance), and the third distance value is subtracted by the preset distance threshold value to obtain the third distance difference (i.e. the distance that the other first side panel 103 can move towards the inside of the box body after reserving the air flow passage distance).

[0040] The first distance difference, the second distance difference, and the third distance difference correspond to the foldable angles, and the minimum foldable angle among the foldable angles corresponding to the first distance difference, the second distance difference, and the third distance difference is folded along the folding line by driving each first side panel 103 according to the control of the driving motor. In this way, after the refrigerated container is folded, each first side panel 103 and the top panel 101 are kept at a certain distance from the inner wall of the refrigerated container.

[0041] According to the type of the refrigerated stacked goods 111, the refrigeration temperature required by the refrigerated stacked goods 111 is determined. The required refrigeration temperature can save power consumption without deteriorating the refrigerated stacked goods 111.

[0042] The type, weight, and refrigeration temperature of the refrigerated stacked goods 111 are input into the pre-trained operation parameter determination model to determine a plurality of sets of operation parameters of the intelligent refrigerated container for keeping each position on the refrigerated stacked goods 111 at the refrigeration temperature, each set of operation parameters including the refrigeration power of the refrigeration equipment, the air outlet speed and direction, and the angle between the extension direction of each electrically operated air deflector 109 to the inside of the box and the horizontal direction. In this way, each position on the refrigerated stacked goods 111 can be kept at the required refrigeration temperature and uniform cooling and heating.

[0043] The refrigeration power and air outlet speed in each set of operation parameters are input into the pre-trained power consumption determination model to determine the power consumption of the refrigeration equipment corresponding to each set of operation parameters; the set of operation parameters corresponding to the minimum power consumption of the refrigeration equipment is selected. According to the refrigeration power of the refrigeration equipment, the air outlet speed and direction in the selected set of operation parameters, the refrigeration equipment is controlled to operate; and each electrically operated air deflector 109 is controlled to rotate so that each electrically operated air deflector 109 reaches the angle between the extension direction to the inside of the box and the horizontal direction in the selected set of operation parameters. In this way, each position on the refrigerated stacked goods 111 can be kept at the required refrigeration temperature and uniform cooling and heating, and the power consumption is minimized, while the occupied space of the refrigerated container is saved, and the practicability is strong.

[0044] In some embodiments, each first side panel 103 is provided with a non-contact temperature sensor 110 on both sides of the folding line thereof, and the geometric center of the box is provided with a contact temperature sensor (for example, provided on a bracket extending into the geometric center of the box, not shown in the drawings). After S208, the method provided by the present application further comprises: Step 1: receiving the temperature of the refrigerated stacked goods 111 collected by each non-contact temperature sensor 110 and receiving the temperature of the refrigerated stacked goods 111 collected by the contact temperature sensor.

[0045] Step 2: determining the actual average temperature of the plurality of received temperatures of the refrigerated stacked goods 111.

[0046] Step 3: determining a difference temperature between the actual average temperature and the refrigeration temperature required by the refrigerated stacked goods 111.

[0047] Step 4: in the case that the difference temperature is greater than the set temperature threshold, updating the first network parameter of the running parameter determination model according to the first reinforcement learning model until the difference temperature is less than or equal to the set temperature threshold, wherein the difference temperature is the reward of the first reinforcement learning model, and the lower the difference temperature, the higher the reward, the first network parameter of the running parameter determination model is the action of the first reinforcement learning model, and the first network parameter is the state of the first reinforcement learning model.

[0048] Based on the above steps 1-4, the actual average temperature of the refrigerated stacked goods 111 can be accurately controlled to the required temperature.

[0049] In some embodiments, in the case that the difference temperature is less than or equal to the set temperature threshold, the method provided by the embodiments of the present application further comprises: Step A: determining the variance of the plurality of temperatures of the received refrigerated stacked goods 111.

[0050] Step B: in the case that the variance of the plurality of temperatures of the refrigerated stacked goods 111 is greater than the preset variance threshold, updating the second network parameter of the running parameter determination model according to the second reinforcement learning model until the variance of the plurality of temperatures of the refrigerated stacked goods 111 is less than or equal to the preset variance threshold, wherein the variance of the plurality of temperatures of the refrigerated stacked goods 111 is the reward of the second reinforcement learning model, and the smaller the variance of the plurality of temperatures of the refrigerated stacked goods 111, the higher the reward, the second network parameter of the running parameter determination model is the action of the second reinforcement learning model, and the second network parameter is the state of the second reinforcement learning model.

[0051] Based on the above, the refrigerated stacked goods 111 at each position can be accurately brought to the required refrigeration temperature and uniformly cooled and heated.
