The image acquiring device may be configured to acquire a real-time image of tea leaves during a tea leaf strip tidying process, and send the image to the control unit 130. The control unit 130 may determine the current color data of the tea leaves based on the images, and further determine how to adjust the operating parameters of the tea carding device in combination with other relevant data, so as to efficiently complete the carding process. For more on adjusting the operating parameters, reference is made to the description in relation to fig. 5.

In some embodiments, the pre-treatment unit 110 and the carding unit 120 of the tea carding device 100 may be connected to each other, and in particular, may be communicated with the pipes 320-1 and 320-2 through the negative pressure fan 310. When the tea strip tidying device is in a working state, the strip tidying unit is in a closed state, and an outlet is connected with the negative pressure fan 310 through a pipeline 320-1. As at least one group of heaters continuously heats the air in the carding unit 120 to evaporate the moisture of the tea leaves to be treated, the air gradually becomes damp and hot air. The negative pressure fan can pump out the damp and hot air in the strip tidying unit 120, and the damp and hot air enters the thermal circulation assembly through a pipeline 320-2 connected with the thermal circulation assembly in the pretreatment unit to provide partial heat for the pretreatment unit to de-enzyme the tea leaves to be treated.

Through leading-in hot circulation subassembly of damp and hot air with in the reason strip unit, the heat energy that can make full use of heater production is favorable to improving the utilization ratio of heat energy.

It should be understood that fig. 3 is only used for illustrating the connection relationship among the components of the tea carding device, and in some cases, the connection mode among the components can be designed according to the actual production requirement.

Fig. 4 is an exemplary flow diagram of a tea carding process according to some embodiments herein. As shown in fig. 4, the process 400 may include the following steps. In some embodiments, the process 400 may be performed based on the tea strip tidying device 100.

And step 410, performing enzyme deactivation on the tea leaves to be processed through the pretreatment unit.

In some embodiments, the tea leaves may be de-enzymed by contact with the processing unit. The tea leaves to be treated may be placed in a pre-treatment cabinet of a pre-treatment unit prior to the treatment for carding. The hot and humid air in the carding unit pumped out by the negative pressure fan enters the thermal circulation assembly of the pretreatment unit through the pipeline, and after the hot and humid air in the thermal circulation assembly starts to circulate, the heat can be released, so that partial heat is provided for the tea leaf enzyme-deactivating treatment.

The tea leaves to be treated after the fixation can be put into a strip tidying unit to enter the subsequent strip tidying treatment.

In some embodiments, the flow rate of the gas drawn out of the carding unit by the negative pressure fan can be obtained by a gas flow meter. The real-time power of the negative pressure fan can be determined based on the flow of the gas, and then the real-time power is used for determining working parameters of all components of the tea carding device.

And step 420, controlling the automatic tea feeding unit to place the tea to be processed with preset quality into the carding unit.

In some embodiments, the control unit 130 may control the automatic tea-leaf-throwing unit to throw tea leaves to be processed with a preset quality into the tea-strip tidying unit for tea-strip tidying processing.

The preset quality can be a suitable tea quality range which can be processed by the carding unit at a single time based on actual production experience. When treating treatment tealeaves through reason strip unit, if the tealeaves of once handling is too much, surpass the load of reason strip unit and can seriously influence the effect of handling, if tealeaves is too little, then can influence holistic production efficiency. Therefore, determining an appropriate tea quality range is particularly important to ensure the effectiveness and efficiency of the carding process.

In some embodiments, the automatic tea dispensing unit may be provided with a weight sensor. When carrying tea leaves, the current weight reduction of the tea leaves can be determined in real time, the total weight of the tea leaves put into the carding unit is determined based on the current weight reduction of the tea leaves, and whether the tea leaves with preset mass are put into the carding unit is judged according to the total weight of the tea leaves put into the carding unit. If yes, the input is stopped. If not, continuing to input.

And 430, processing the tea leaves to be processed based on the relevant working parameters through the carding unit.

In some embodiments, processing the tea leaves to be processed based on the relevant working parameters may include determining the working parameters of the components of the tea carding device, processing the tea leaves to be processed based on the determined working parameters; the method can also comprise the steps of determining how to adjust the working parameters of all the components of the tea strip tidying device to meet the current processing requirement, and processing the tea to be processed based on the adjusted working parameters.

In some embodiments, the control unit may generate a control instruction including the parameter and capable of being analyzed by the corresponding unit according to the unit that needs to be controlled and the parameter that needs to be adjusted by the unit, so that the component unit that receives the control instruction adjusts the working parameter corresponding to the value by analyzing the control instruction.

In some embodiments, the control command may include data related to operating parameters of the strip tidying unit, and the device receiving the control command may adjust to the corresponding operating parameters according to the data in response to the control command.

In some embodiments, the operating parameter may include at least one of an operating parameter of the at least one heater and an operating parameter of the reflective surface of the heater. The working parameters of at least one group of heaters can influence the efficiency of tea strip tidying treatment, and the temperature in the strip tidying unit cannot meet the production requirement due to too high or too low power, so that the flavor of tea leaves is damaged, and therefore, the smooth operation of the strip tidying treatment can be ensured by determining the proper working parameters of the heaters.

In some embodiments, the operating parameters of the reflective surface of the heater may include the angle, frequency, etc. of rotation of the reflective surface. The rotation angle and the frequency of the reflecting surface of the heater can influence the heat distribution in the carding unit, and the uniform heat distribution can ensure the color of tea leaves in the carding unit to be consistent, so that the uniform heat distribution in the carding unit can be ensured by determining the proper rotation angle and frequency.

In some embodiments, the operating parameters further include operating parameters of a fan of the carding unit.

In some embodiments, the power of the fan may affect the internal wind speed of the carding unit. When the air in the tea tidying unit flows through the fan and blows tea leaves, so that tea leaf tidying methods such as grabbing and throwing of workers can be simulated, the model effect meeting production requirements can be achieved by determining the power of the reasonable fan, and the quality of the processed tea leaves is guaranteed.

In some embodiments, the operating parameter may further include an operating parameter of the negative pressure air blower, and specifically may include a power of the negative pressure air blower and the like.

In some embodiments, the power of the negative pressure fan may affect the efficiency of extracting the moist, hot air inside the carding unit. When the negative-pressure fan can timely pump out the damp and hot air in the carding unit, the negative-pressure fan can avoid the damp and hot air from generating adverse effects on tea leaves and influencing the flavor of the tea leaves, and therefore the damp and hot air can be timely transferred by determining the reasonable negative-pressure fan power.

In some embodiments, the operating parameters of the components of the current tea carding device may be determined from the temperature data, humidity data and odor data of the carding process in the historical data and the corresponding historical operating parameters of the components of the tea carding device. For example, similar history entries for normally executing the tea carding process can be searched from the history data according to the current temperature data, humidity data and smell data, and the current working parameters can be determined according to the historical working parameters of all the components of the tea carding device of the history entries.

In some embodiments, whether the current temperature meets the requirements of the strip arranging process can be judged according to the temperature data acquired by the sensor. For example, when the temperature data is below a preset threshold (or threshold range), the power of the heater may be increased; when the temperature data is higher than a preset threshold (or threshold range), the power of the heater may be reduced.

In some embodiments, the temperature data may also include temperatures at a plurality of temperature detection points. The temperatures of the plurality of temperature detection points may reflect the temperature distribution inside the carding box 210. In some embodiments, the reflective surface rotation angle, frequency, etc. of the heater may be adjusted based on the temperature of the plurality of temperature detection points.

In some embodiments, the humidity data may reflect whether or not parameters associated with the negative pressure fan need to be included in determining the temperature-related operating parameters.

In some embodiments, the operating parameter included in the control command may be determined according to a relationship between the related parameter detected by the sensor and a corresponding preset threshold. The preset threshold may refer to a working parameter when the strip sorting process is normally performed. For example, if the temperature parameter detected by the sensor is smaller than the corresponding preset threshold, the control unit may generate a control command (e.g., increase the power of the heater 220, decrease the power of the negative pressure fan, etc.) for increasing the temperature of the carding box 210.

In some embodiments, the influence between the respective relevant parameters may also be taken into account when determining the control instructions. For example, when the temperature parameter detected by the sensor is smaller than the corresponding preset threshold, if the reduction of the power of the negative pressure fan may result in the air humidity being increased and higher than the preset threshold, the control instruction may be generated by combining the air humidity parameter and the temperature parameter. That is, when the temperature parameter detected by the sensor is smaller than the corresponding preset threshold, if the air humidity parameter is far smaller than the corresponding preset threshold, the power of the negative pressure fan can be reduced. Otherwise, the power of the negative pressure fan cannot be reduced.

In some embodiments, the control unit 130 may determine control commands, adjust the operating parameters of the at least one heat-receiving gas, and the operating parameters of the suction air fan.

In some embodiments, the control unit 130 may generate an instruction for adjusting the power of the negative pressure fan based on the real-time power of the negative pressure fan in combination with the data related to the tea leaves to be processed, and adjust the power of the negative pressure fan based on the instruction. The real-time power of the negative pressure fan may be determined by the gas flow rate obtained by the gas flow meter in real time, which may be specifically described in step 410.

In some embodiments, the control unit may adjust the operating parameters of the at least one set of heaters and the operating parameters of the negative pressure fan based on the relevant data of the tea leaves to be processed by adjusting the model, for more details, see fig. 5 and its associated description.

It should be noted that the above description related to the flow 400 is only for illustration and description, and does not limit the application scope of the present specification. Various modifications and changes to flow 400 will be apparent to those skilled in the art in light of this description. However, such modifications and variations are still within the scope of the present specification.

In some embodiments, the control instructions may be determined based on the image of the tea leaves to be processed by adjusting the model, adjusting the operating parameters of the at least one set of heaters, and the operating parameters of the negative pressure fan.

In some embodiments, the tuning model 510 may include one or more of a Convolutional Neural Network (CNN) model, a Recurrent Neural Network (RNN) model, a Deep Neural Network (DNN) model, and the like.

In some embodiments, the adjustment model 510 may also include other models that can accomplish the same process, depending on the actual needs.

In some embodiments, the inputs to the adjustment model 510 may include at least the current tea color data 520 and the target color 530 for the next point in time.

Wherein the current tea color data 520 may be acquired based on an image of the tea to be processed. For example, the image of the tea to be processed may be processed through an image feature extraction algorithm, so as to obtain the color data of the current tea. For another example, the color data of the current tea leaves can be judged manually based on the images of the tea leaves to be processed and input into the control unit of the tea leaf strip tidying device. The image of the tea leaves to be processed may be a tea leaf image in which the carding process has not been started, or may be a tea leaf image in which the carding process has been performed but the processing has not been completed.

The target color 530 at the next point in time may be determined manually based on actual production requirements and input into the control unit of the tea carding device. The next time point may be determined manually, or may be a fixed time threshold, for example, the next time point may be after 5 minutes, after 10 minutes, or the like.

In some embodiments, the output of the adjustment model 510 may include the operating parameters 540 of the negative pressure fan and the operating parameters 550 of the at least one set of heaters at the next point in time.

In some embodiments, the inputs to the adjustment model 510 may also include tea leaf scent data, wherein the tea leaf scent data includes at least tea leaf scent concentration data. In some embodiments, the tea leaf scent data may be determined based on a scent sensor disposed within the tidying bin.

The tea leaves are subjected to strip tidying treatment, so that the tea leaves can be quickly dehydrated and improved in fragrance, and a better flavor is obtained. The odor data of the tea leaves are obtained and used as the input of the adjustment model, so that the input of the model is increased, and on the premise of considering more conditions, the model can better determine how to adjust the working parameters of the negative pressure fan and the heater.

In some embodiments, the inputs to the adjustment model 510 may also include the current operating parameters of the heater, as well as the temperature and humidity within the current tidying bin. The current operating parameters of the heater may include the current rotation angle and rotation frequency of the reflecting surface of the heater, and the current power of the heater. In some embodiments, the current operating parameters of the heater may be determined by the control unit based on current operating data of the tea carding device, and the temperature and humidity within the current carding cabinet may be determined based on a temperature sensor and a humidity sensor provided within the carding cabinet, respectively.

By acquiring the current working parameters of the heater and the current temperature and humidity in the tea strip tidying box and taking the current working parameters as the input of the adjustment model, the current working state of the tea strip tidying device can be fully considered, and the adjustment of the working parameters of the negative pressure fan and the heater can be more accurately determined on the basis of the actual processing condition, so that the adjusted working parameters are more suitable for the actual condition.

In some embodiments, the adjustment model 510 may be trained based on a large number of labeled training samples. For example, a plurality of labeled training samples may be input into the initial adjustment model 511, a loss function may be constructed from the labels and the results output by the initial adjustment model 511, and parameters of the initial adjustment model 511 may be iteratively updated by gradient descent or other methods based on the loss function. When the preset conditions are met, the model training is completed, and a trained adjustment model 510 is obtained. The preset condition may be that the loss function converges, the number of iterations reaches a threshold, and the like.

In some embodiments, the training sample may include historical current tea color data 511-1 and historical target color 511-2. In some embodiments, the training samples may be obtained based on historical processing data of the tea strip tidying device. In some embodiments, the training samples may also include historical odor data of the tea leaves, historical operating parameters of the heater, historical temperature and historical humidity within the tidying cabinet, and the like.

In some embodiments, the trained tag may include historical operating parameters 511-3, wherein the historical operating parameters 511-3 may include at least the negative pressure fan historical operating parameters (e.g., historical power of the negative pressure fan, etc.), the historical operating parameters of the at least one set of heaters (e.g., historical rotational angle, historical rotational frequency, historical power of the at least one set of heaters, etc.). In some embodiments, the trained labels may be obtained based on historical processing data of the tea strip tidying device, or may be obtained by manual labeling.

Having thus described the basic concept, it will be apparent to those skilled in the art that the foregoing detailed disclosure is to be regarded as illustrative only and not as limiting the present specification.
