[0063] When the display panel is stored in the storage device in the production workshop, the fan filter unit needs to run at high speed to meet the environmental state requirements for storing the display panel. As a result, the storage device consumes a large amount of electricity. To solve this problem, the storage device is optimized to reduce power consumption and save energy. Please refer to Figures 1 to 4 , Figure 1 The flowchart showing the control method of the storage device in an embodiment of the present invention. Figure 2 The schematic structural diagram showing the storage device in an embodiment of the present invention. Figure 3 The schematic structural diagram showing the bin 11 in an embodiment of the present invention. Figure 4 The schematic management block diagram showing the storage device in an embodiment of the present invention. In one embodiment, the production workshop includes a storage device 10 and a handling device 20. The storage device 10 has a plurality of bins 11. Each of the plurality of bins 11 has a fan filter unit 14. The fan filter unit 14 is used to make the air in the bin 11 flow through the fan to meet the environmental requirements of the storage device 10. The plurality of bins 11 are used to store storage components 12. Each storage component 12 is used to accommodate a target product 13. Each storage component 12 can be stored or taken out in the plurality of bins 11 through the handling device 20. In one embodiment, the storage component 12 can be a cassette, and the target product 13 can be a display panel (specifically, a display panel in the production process, etc.). In one embodiment, the present invention proposes a control method for a storage device, which includes the following steps:

[0064] Step S1: Provide a production management system 100, in which the position information of each storage grid 11 in the storage device 10 is stored, and obtain the current storage status and current handling command corresponding to each position information to confirm the storage status information of the multiple storage grids 11;

[0065] Step S2: Control the motor speed of the fan filter unit 14 in each storage grid 11 according to the storage status information of each storage grid 11. Among them, the rotation speeds of the fan filter units 14 of the storage grids 11 in different storage states are different.

[0066] In the present invention, the production management system 100 is used to obtain the position information, current storage status, and current handling command of each storage grid 11 in the storage device to confirm the storage status information of the multiple storage grids 11, and adaptively adjust / control the motor speed of the fan filter unit 14 in each storage grid 11 according to the storage status information of each storage grid 11, so that the motor speed of the fan filter unit 14 in each storage grid 11 matches the storage status of the storage device 10, flexibly control the power consumption of the storage device, and save energy; and integrate the manufacturing execution system, etc. with the warehouse management, which is convenient for data analysis, production management, etc.

[0067] In an embodiment, the production management system 100 may include a manufacturing execution system MES (Manufacturing Execution System) and a material control system MCS (Material Control System). In step S1, the production management system 100 may assign an address to each storage grid 11 to represent its position information, and then represent the storage status of the storage grid 11 through a data structure corresponding to the position information (the storage status of the storage grid 11 may include whether there is a storage component 12 stored in the storage grid 11, the information of the target product 13 stored in the storage component 12, etc.). The production management system 100 obtains the current handling command according to the production task (including the pick / place action of the handling device 20, the target storage grid address, etc.). The production management system 100 determines the storage status information of each storage grid 11 according to the foregoing position information, the storage status corresponding to the position information, and the current handling command. In this embodiment, since the position information, current storage status, current handling command, etc. of each storage grid 11 are obtained through the production management system 100, there is no need to additionally set an induction component in each storage grid 11 to determine the storage status of each storage grid 11, which reduces the production cost and wiring difficulty, etc. It should be noted that the implementation manner of step S1 is not limited to the implementation manner of this embodiment, and any manner that can implement step S1 is acceptable. For example, whether there is a storage component 12 stored in the storage grid 11 can be obtained according to the induction device in the storage grid 11, or it can be updated according to the return result of the handling command, so that there is no need to additionally set an induction device, saving costs.

[0068] In one embodiment, the method further includes constructing corresponding three-dimensional models for the production workshop, the storage device 10, the handling device 20, the storage component 12, and the target product 13 respectively; importing each three-dimensional model into the digital twin system to generate a virtual three-dimensional model of the corresponding storage system, and connecting the virtual three-dimensional model to the production management system; the virtual three-dimensional model real-time senses the position information of each storage bin 11 in the storage device 10 in the production management system, and automatically obtains the current storage state and the current handling command corresponding to each position information, so as to automatically calculate and confirm the storage state information of multiple storage bins 11; analyzing the storage state information of each storage bin 11 in the virtual three-dimensional model to select the optimal motor speed of the fan filter unit 14 in each corresponding storage bin 11, and outputting it as a control instruction to the corresponding fan filter unit 14. Among them, the optimal motor speeds of the fan filter units 14 of the storage bins 11 in different storage states are different. In this embodiment, a virtual three-dimensional model of the corresponding storage system is established. Through real-time automatic sensing and automatic calculation, the storage state information in the storage device 10 is obtained. Furthermore, rules are derived through self-learning of the data model, and the virtual three-dimensional model automatically decides the best result (that is, the optimal motor speed of each fan filter unit), so that the storage system can adaptively adjust parameters according to the current storage state, maintain the best characteristics and functions, flexibly control the power consumption of the storage device, save energy, and form a full closed-loop control.

[0069] In one embodiment, the step of controlling the motor speed of the fan filter unit 14 in each storage bin 11 according to the storage state information of each storage bin 11 further includes:

[0070] The multiple storage bins 11 include a first storage bin 11. When the first storage bin 11 stores the storage component 12, control its corresponding fan filter unit 14 to a first speed;

[0071] The multiple storage bins 11 include a second storage bin 11. When the second storage bin 11 does not store the storage component 12, control its corresponding fan filter unit 14 to a second speed, and the second speed is not greater than the first speed.

[0072] When there is a storage component 12 in the storage bin 11, the back pressure of the air flow is relatively large, and the fan filter unit 14 needs a higher rotational speed to make the air flow. When there is no storage component 12 in the storage bin 11, there is no back pressure for the air flow in the storage bin 11. Therefore, the rotational speed of the fan is appropriately reduced to reduce energy consumption. For example, the second rotational speed is 90% of the first rotational speed, that is, when there is no storage component 12, the rotational speed of the fan is reduced by 10%, but this is not limiting, and it can be adjusted according to the actual situation. Further, when there is a storage component 12 in the storage bin 11, the rotational speed of the fan can be controlled according to the size of the storage component 12 stored in the storage bin 11 and the distance between the storage component 12 and the fan filter unit 14 to obtain the magnitude of the back pressure of the air flow. The greater the back pressure, the higher the rotational speed of the fan, and the smaller the back pressure, the smaller the rotational speed of the fan. The rotational speed of the fan is controlled to be between the first rotational speed and the second rotational speed.

[0073] In an embodiment, when a first storage component 12 is stored in the first storage bin 11, it is confirmed in the production management system 100 whether the first storage component 12 contains the target product 13 and the current manufacturing process step of the target product 13, and the rotational speed of the fan filter unit 14 corresponding to the first storage bin 11 is further adjusted according to the current manufacturing process step. For whether the target product 13 is stored or not stored in the first storage component 12, or because the current manufacturing process step (stage) of the target product 13 is different, the required rotational speed of the fan filter unit 14 may be different. Therefore, while ensuring that the environmental requirements for storing each target product 13 are met, the rotational speed of the fan filter unit 14 can be further adaptively adjusted / controlled according to whether the target product 13 is stored in the storage component 12 and the current manufacturing process step, so that the motor rotational speed of the fan filter unit 14 in each storage bin 11 not only matches the storage state of each storage bin 11, but also further precisely matches the current manufacturing process step of the target product 13 in each storage component 12, etc., flexibly controlling the power consumption of the storage device and reducing the energy consumption of the storage equipment.

[0074] In one embodiment, when it is confirmed that the target product 13 is not accommodated in the first storage component 12, the environmental requirements are relatively low at this time. The corresponding fan filter unit 14 is adjusted to the third rotation speed, and the third rotation speed is between the first rotation speed and the second rotation speed, so that the rotation speed of the fan filter unit 14 is slightly decreased based on the first rotation speed. For example, it is 95% of the first rotation speed (not limited thereto); alternatively, when it is confirmed that the target product 13 is accommodated in the first storage component 12 and the current process step of the target product 13 is a first type of process step, the environmental requirements are relatively low at this time, then the corresponding fan filter unit 14 is adjusted to the fourth rotation speed, and the fourth rotation speed is between the first rotation speed and the second rotation speed, so that the rotation speed of the fan filter unit 14 is slightly decreased based on the first rotation speed. For example, it is 95% of the first rotation speed (not limited thereto); alternatively, when it is confirmed that the target product 13 is accommodated in the first storage component 12 and the current process step of the target product 13 is a second type of process step, the environmental requirements are high at this time, then the corresponding fan filter unit 14 is maintained at the first rotation speed. In one embodiment, the first type of process step is, for example, steps such as substrate cutting and module assembly, and the second type of process step is, for example, steps such as substrate cleaning, etching, thin film deposition, and alignment film coating. Since the requirements for the number of particles in the air are different for the first type of process step and the second type of process step, the rotation speed of the fan filter unit 14 is further adaptively adjusted / controlled according to the current process step of the target product 13, so that the motor rotation speed of each fan filter unit 14 matches the current process step of the target product 13 in each storage component 12, reducing the energy consumption of the warehousing equipment.

[0075] In one embodiment, the method further includes obtaining the environmental state information of the warehousing device 10, and performing logistic regression based on the storage state information of each storage cell 11 and the environmental state information to control the motor rotation speed of the fan filter unit 14 in each storage cell 11.

[0076] Please refer to again Figure 4, in one embodiment, the storage state information of each storage cell 11 is defined as the first influencing factor and has a first weight, and the environmental state information is defined as the second influencing factor and has a second weight. The rotation speed of the fan filter unit 14 corresponding to each storage cell 11 is controlled according to the first influencing factor, the second influencing factor, the first weight, and the second weight. According to the formula y = AX1 + BX2, where y is the rotation speed of the fan filter unit 14 corresponding to each storage cell 11, A is the first weight, B is the second weight, X1 is the first influencing factor (the storage state information of each storage cell 11), and X2 is the second influencing factor (environmental state information). Further, the storage state information of each storage cell 11 can be further divided into whether the storage component 12 is stored in the storage cell 11, whether the target product 13 is stored in the storage component 12, the current manufacturing process step of the target product 13, etc. The environmental state information can be further divided into the particle state information in the storage device 10, the temperature in the storage device 10, the humidity in the storage device 10, and the wind speed in the storage device 10. Each factor is used as an influencing factor to perform a regression analysis on the rotation speed of the fan filter unit 14 corresponding to each storage cell 11. The environmental state information can be obtained by the environmental state information acquisition device 30 and reported to the production management system 100. The production management system 100 controls the rotation speed of the fan filter unit 14 according to the results of the regression analysis. In this embodiment, the regression analysis can use models such as decision tree, linear regression, polynomial regression, random forest, gradient boosting tree, neural network, etc., but is not limited thereto.

[0077] In one embodiment, the steps of performing logistic regression according to the storage state information of each storage cell 11 and the environmental state information to control the motor rotation speed of the fan filter unit 14 in each storage cell 11 further include:

[0078] Adjust the motor rotation speed of the fan filter unit 14 in each storage cell 11 according to the particle state information in the storage device 10;

[0079] Adjust the motor rotation speed of the fan filter unit 14 in each storage cell 11 according to the temperature / humidity in the storage device 10; and / or,

[0080] Adjust the motor rotation speed of the fan filter unit 14 in each storage cell 11 according to the wind speed in the storage device 10.

[0081] In one embodiment, the above steps of controlling the motor rotation speed of the fan filter unit 14 in each storage cell 11 according to the storage state information of each storage cell 11 can be implemented in the production management system 100 or can be implemented by an independent control module outside the production management system 100. The control instructions for the fan filter unit 14 and the handling unit 20 by the production management system 100 or the independent control module can be controlled by a programmable logic controller PLC, but the present invention is not limited thereto.

[0082] Please refer to Figure 5 , Figure 5 which shows a flowchart of the abnormal detection of a storage device in an embodiment of the present invention. In one embodiment, the method further includes the steps of:

[0083] Step S31: Monitor the number of particles in the storage device 10;

[0084] Step S32: Determine whether the single-point measurement exceeds the first quantity per minute. If the result is no, execute Step S33; if the result is yes, execute Step S34;

[0085] Step S33: Determine whether there is a preset number of measurements exceeding the second quantity per minute within a preset time. The second quantity is different from the first quantity. If the result is no, execute Step S31; if the result is yes, execute Step S34;

[0086] Step S34: Perform abnormal detection on the storage components 12 and the fan filter unit 14 in each storage bin 11. In one embodiment, the first quantity is greater than the second quantity. For example, the first quantity is 10 particles, the second quantity is 5 particles, the preset time is 10 minutes, and the preset number of measurements is 3. These values can be adjusted according to the actual situation and are not limited thereto.

[0087] In one embodiment, after Step S34, abnormal problem elimination is also performed, and it is determined whether the abnormal state has been eliminated. If so, return to Step S31; if not, perform abnormal problem elimination again.

[0088] In addition, the present invention also provides another method for controlling a storage device. The storage device 10 is located in a production workshop, and the production workshop also includes a handling device 20, etc. The storage device 10 has a plurality of storage bins 11, each of which has a fan filter unit 14. The plurality of storage bins 11 are used to store storage components 12, and each storage component 12 is used to accommodate a target product 13. Each storage component 12 can be stored or retrieved in the plurality of storage bins 11 through the handling device 20. The method includes the following steps:

[0089] Construct corresponding three-dimensional models for the production workshop, the storage device 10, the handling device 20, the storage components 12, and the target product 13 respectively; import each three-dimensional model into a digital twin system to generate a virtual three-dimensional model of the corresponding storage system, and the virtual three-dimensional model is connected to a production management system;

[0090] The virtual three-dimensional model real-time senses the position information of each storage bin 11 in the storage device 10, and automatically obtains the current storage state and the current handling command corresponding to each position information, so as to automatically calculate and confirm the storage state information of the plurality of storage bins 11;

[0091] Analyze the storage state information of each bin 11 in the virtual 3D model to select the optimal motor speed of the fan filter unit 14 corresponding to each bin 11, and output it as a control command to the corresponding fan filter unit 14. Among them, the optimal motor speeds of the fan filter units 14 of the bins 11 in different storage states are different.

[0092] In one embodiment, the method further includes that the virtual 3D model senses the environmental state information of the storage device 10 in real time; analyze the storage state information of each bin 11 and the environmental state information in the virtual 3D model to select the optimal motor speed of the fan filter unit 14 corresponding to each bin 11, and output it as a control command to the corresponding fan filter unit 14. It should be noted that the calculation rules, consideration factors, etc. mentioned in the control method described above also apply to this embodiment and will not be elaborated here.

[0093] In this embodiment, a virtual 3D model corresponding to the storage system is established. Through real-time automatic sensing and automatic calculation, the storage state information in the storage device 10 can be obtained. Further, the environmental state information can also be obtained. Then, rules are derived through self-learning of the data model, and the virtual 3D model makes a self-decision on the best result (that is, the optimal motor speed corresponding to each fan filter unit). Thus, the storage system can adaptively adjust parameters according to the current storage state (further, it can also be according to environmental changes, etc.), maintain the best characteristics and functions, flexibly control the power consumption of the storage device, save energy, and form a full closed-loop control.

[0094] In one embodiment, the virtual 3D model can use online learning and reinforcement learning methods to self-learn and decide the optimal motor speed corresponding to each fan filter unit. The online learning method is an incremental learning method. The virtual 3D model can continuously update parameters when new data arrives. As mentioned above for the speed regression problem of the fan filter unit 14, the stochastic gradient descent (SGD) method can be used to implement online learning. In reinforcement learning, the output of the model is used as an action, and the feedback of the power consumption of the storage system generated by the speed of each fan filter unit 14 is used as a reward signal to guide the update of the model to optimize the weight parameters of the virtual 3D model. It should be noted that the above implementation methods of online learning and reinforcement learning can be realized through existing frameworks and will not be elaborated here.
