[0044] The technical scheme can shorten the heating time, so that the clean greenhouse can reach the temperature setting range more quickly in a short time. Since the system uses split excitation heating, the temperature difference adjustment work of about 15℃ is divided into two stages to complete, so the temperature difference adjustment range that needs to be completed by each stage of heating adjustment is reduced, and the heating time is greatly shortened. At the same time, the damage to the equipment can be reduced, and the service life of the electric heater can be prolonged. The new technology uses split excitation heating to avoid the electric heater completing a higher temperature difference adjustment in a short time. In addition, the room temperature of the clean greenhouse at a future time point can be predicted in advance, so that heating can be performed in advance to ensure the stability of the temperature of the clean greenhouse.

[0048] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0049] On the contrary, the present application covers any alternative, modification, equivalent method and scheme defined by the claims within the essence and scope of the present application. Further, in order to make the public better understand the present application, some specific details are described in detail in the following detailed description of the present application. The present application can also be completely understood without the description of these details by those skilled in the art.

[0050] The following will be combined with Figures 1-3 A split excitation adjustment control method for a clean greenhouse according to an embodiment of the present application will be described in detail. It should be noted that the following embodiments are only used to explain the present application and do not limit the present application.

[0051] Embodiment 1

[0052] As shown in Figure 1 , the present application also discloses a split excitation adjustment control system 100 for a clean greenhouse, comprising:

[0053] A first heating device 110 is configured to heat the air obtained from the outside. For example, the first heating device 110 can be a heating device installed in a heating section of the air conditioner, such as a heating coil.

[0054] A second heating device 120 is configured to heat the air heated by the first heating device and deliver the air into the clean room. In some embodiments, the second heating device 120 can be a heating device installed on a supply duct of the interlayer section, such as a heating coil, a heating plate, or the like.

[0055] A first temperature sensor 130 is configured to obtain a first temperature of the air heated by the first heating device and before being heated by the second heating device. For example, the first temperature sensor 130 can be installed on the supply duct at a position between the output end of the first heating device and the input end of the second heating device, to obtain the temperature of the air entering the second heating device.

[0056] A second temperature sensor 140 is configured to obtain a second temperature of the air heated by the second heating device. For example, the second temperature sensor 140 can be installed on the supply duct at the output end of the second heating device, to obtain the temperature of the air entering the clean room.

[0057] A third temperature sensor 150 is configured to obtain a third temperature of the air in the clean room. In some embodiments, the number of the third temperature sensors 150 can be multiple, such as temperature sensors installed at multiple preset positions in the clean room to obtain the temperature near the positions. In some embodiments, the average or weighted sum of the temperatures obtained at the multiple positions can be used as the third temperature.

[0058] A controller 160 is configured to determine the working state and working parameters of the first heating device and / or the second heating device based on the first temperature, the second temperature, and the third temperature. For example, when a certain temperature does not meet a preset temperature range, the controller 160 can determine that the current room temperature is abnormal, and then control the corresponding heating device to heat the room temperature.

[0059] In some embodiments, the controller is further configured to:

[0060] determine whether the third temperature meets a first preset requirement;

[0061] in response to the third temperature not meeting the first preset requirement, determine whether the second temperature meets a second preset requirement;

[0062] in response to the second temperature meeting the second preset requirement, control the second heating device to heat the air.

[0063] The first preset requirement can be a preset room temperature standard range, which can be set according to actual conditions. If the room temperature meets the preset requirement, each heating device can maintain the current working state. If the room temperature exceeds the preset room temperature standard range, it is further determined whether the second preset requirement is met. The second preset requirement can be a room temperature range corresponding to the working of the second heating device. The specific range value can be set according to actual conditions.

[0064] In some embodiments, the controller is further configured to:

[0065] In response to the second temperature not meeting the second preset requirement, it is determined whether the first temperature meets a third preset requirement.

[0066] In response to the first temperature meeting the third preset requirement, the first heating device is controlled to heat the air.

[0067] The third preset requirement can be a room temperature range corresponding to the working of the first heating device. The specific range value can be set according to actual conditions.

[0068] In some embodiments, the temperature range corresponding to the second preset requirement is greater than the temperature range corresponding to the first preset requirement. For example, a preset temperature length can be used as a range corresponding temperature length value. For example, 0-30 degrees Celsius, and every 15 degrees can be used as a temperature range, which respectively correspond to the temperature range corresponding to the second preset requirement and the temperature range corresponding to the first preset requirement.

[0069] In some embodiments, the controller is further configured to:

[0070] In response to the first temperature not meeting the third preset requirement, an alarm is issued. If the first temperature does not meet the third preset requirement, it can be considered that an over-temperature, such as an over-high-temperature, situation occurs, and the staff needs to be notified for emergency treatment. The alarm mode includes but is not limited to voice notification, light warning, etc.

[0071] As shown in FIG. Figure 2 The application further discloses a split excitation adjustment control method for a clean greenhouse, which is executed based on the controller of the split excitation adjustment control system for the clean greenhouse. The method comprises the following steps:

[0072] In step 210, a third temperature is obtained.

[0073] In step 220, based on the third temperature, the working state of the first heating device and / or the second heating device is determined.

[0074] In some embodiments, the third temperature is a plurality of historical temperatures of the air in the clean room within a preset historical time period; and the determining of the working state of the first heating device and / or the second heating device based on the third temperature comprises:

[0075] The third temperature is processed based on a temperature prediction model to determine a predicted temperature of the air in the clean room at a preset time point; and the temperature prediction model is a machine learning model.

[0076] The working state of the first heating device and / or the second heating device is determined based on the predicted temperature.

[0077] For example, the temperature prediction model can predict the room temperature at a future time point based on the processing of the historical room temperature, so that the controller can make corresponding processing preparation in advance based on the predicted room temperature. For example, the corresponding heating device is controlled to heat the air in advance. For specific description of the temperature prediction model, please refer to Figure 3 .

[0078] In some embodiments, step 220 specifically comprises the following steps:

[0079] Step 221: determining whether the third temperature meets a first preset requirement;

[0080] Step 222: in response to the third temperature not meeting the first preset requirement, determining whether the second temperature meets a second preset requirement;

[0081] Step 223: in response to the second temperature meeting the second preset requirement, controlling the second heating device to heat the air;

[0082] Step 224: in response to the second temperature not meeting the second preset requirement, determining whether the first temperature meets a third preset requirement;

[0083] Step 225: in response to the first temperature meeting the third preset requirement, controlling the first heating device to heat the air;

[0084] Step 226: in response to the first temperature not meeting the third preset requirement, issuing a warning.

[0085] As shown in Figure 3 The schematic diagram of the temperature prediction model disclosed in the present embodiment is shown. As shown in Figure 3 In some embodiments, the prediction model 320 can be a machine learning model, for example, a model constructed by neural networks (NNs) or other intelligent learning networks.

[0086] In some embodiments, the input of the temperature prediction model is a third temperature, the third temperature being a historical temperature sequence composed of a plurality of historical temperatures of the air in the clean greenhouse in a preset historical time period, the historical temperature sequence can be represented based on a vector, each vector element corresponding to a room temperature at a historical time point. For example, the historical state sequence is (A, B, C, D…), wherein element A represents the room temperature of the clean greenhouse at a first historical time point (for example, 2 pm last Monday or 10 am today), element B represents the room temperature of the clean greenhouse at a second historical time point (for example, 2 pm last Tuesday or 11 am today), and so on. The output of the temperature prediction model is a room temperature at a future time point, for example, the predicted room temperature of the clean greenhouse at 2 pm today. In some embodiments, the output of the temperature prediction model is also a predicted temperature sequence, which can include temperature values corresponding to a plurality of time points such as 2 pm, 3 pm, and so on.

[0087] In some embodiments, the prediction model can be trained based on a large amount of first training data 340 (including first training samples with first labels). The first training sample can be a historical temperature sequence of the clean greenhouse at a first historical time. The first label can be a historical temperature or a historical temperature sequence of the clean greenhouse at a second historical time, wherein the first historical time is earlier than the second historical time.

[0088] In some embodiments, the training of the initial temperature prediction model 350 includes inputting the first training sample into the initial temperature prediction model 350 to obtain a future temperature sequence corresponding to the first training sample. During the training process, the temperature prediction model can construct a loss function based on the label and the output result. At the same time, the parameters of the temperature prediction model are updated based on the loss function until a preset condition is met, and the training is completed. The preset condition can include one or more of the following: the loss function is less than a threshold, convergence, or the training period reaches a threshold.

[0089] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
