When the volume of the chamber 110 is half of the predefined standard volume, the server 180 can rescale the interval of the gas danger level to 2, 4, 6, 8, 10, and the volume of the chamber 110 In the case of half of this predefined standard capacity, the server 180 can rescale to 0.5, 1, 1.5, 2, 2.5 intervals of the gas hazard level. Through this, the server 180 may adjust the gas to be discharged according to the capacity of the chamber 110. Through this, it is possible to reduce unnecessary discharge of components necessary for manufacturing the hard coating solution from the chamber 110 during normal operation. In addition, when an accident occurs, the gas can be controlled to be discharged according to the capacity of the chamber 110.

Subsequently, the server 180 may obtain gas pressure and chemical components for each predefined unit (330).

The chamber 110 may be divided into predefined units. The predefined units may include a lower part, a middle part, an upper part, a side part, an inner part, a vicinity of the first pipe 140, a vicinity of the second pipe 150, and the like. The sensors of the sensor group 160 can measure the pressure and chemical components of the chamber 110 in predefined units. The sensors of the sensor group 160 may transmit measured values of the pressure and chemical composition of the chamber 110 in predefined units to the communication means 170. The communication means 170 may transmit the measured values of the pressure and chemical composition of the chamber 110 in predefined units to the server 180.

Thereafter, the server 180 may adjust the degree of opening of the second valve 151 based on the gas pressure and chemical constituents for each predefined unit (340 ).

For example, the server 180 sets the gas risk level of the hard coating liquid manufacturing apparatus 100 by averaging the gas pressure and chemical constituents by predefined units, and the second valve 151 according to the set gas risk level. The degree of opening of) can be adjusted. Alternatively, the server 180 is a unit requiring special attention among predefined units, for example, based on the gas pressure and chemical components near the first pipe 140 or near the second pipe 150, the hard coating solution The gas risk level of the manufacturing apparatus 100 may be set, and the degree of opening of the second valve 151 may be adjusted according to the set gas risk level. The server 180 sets the gas risk level of the hard coating liquid manufacturing apparatus 100 by combining the gas pressure and chemical components for each predefined unit in some way, and the second valve 151 according to the set gas risk level. The method of adjusting the degree of opening of may be differently employed depending on the embodiment.

Meanwhile, a specific value of the degree to which the second valve 151 opens according to the gas pressure and chemical components of each predefined unit may be determined based on the inference of the artificial neural network. The detailed learning process of the artificial neural network will be described later with reference to FIG. 6.

Through the above, the server 180 rescales the gas danger level according to the standard information of the hard coating liquid device 100, and rescales the gas pressure and chemical components by predefined units of the chamber 110. The degree of opening of the second valve 151 may be adjusted according to the danger level of the gas. By rescaling the gas risk level according to the capacity of the hard coating solution manufacturing apparatus 100, it is possible to reduce unnecessary discharge of components necessary for manufacturing the hard coating solution from the chamber 110 in normal times, and the chamber 110 It can be controlled so that the gas is discharged according to the capacity. In addition, in accordance with the purpose of using the hard coating solution manufacturing apparatus 100-mass production, small production, experimentation, etc., certain units of gas pressure and chemical components among predefined gas pressures and chemical constituents are reduced to gas risk. You can choose to decide the level or choose. Through this, it is possible to efficiently and stably use the hard coating solution manufacturing apparatus 100 according to the purpose of using the hard coating solution manufacturing apparatus 100.

4 is a flow chart for explaining a first valve and a second valve control operation according to an embodiment.

A method of checking whether the chamber 110 of the hard coating liquid manufacturing apparatus 100 has been supplied with heat per hour required for each process may be performed by measuring the temperature through the sensor group 160. When the chamber 110 does not receive heat per hour required for each process, the flow rate of the first solvent flowing into the chamber 110 through the first pipe 140 may be increased. Through this, more heat is transferred to the chamber 110, and an environment required for manufacturing the hard coating solution may be created.

At this time, the specific heat capacity of the first solvent changes according to the ratio of acid contained in water. Therefore, even if the first solvent is at the same temperature, the heat per hour supplied to the chamber 110 may vary according to the ratio of the acid contained in the first solvent.

More specifically, the more acid is contained in water, the lower the specific heat capacity of the first solvent. The lower the specific heat capacity of the first solvent, the smaller the amount of heat it contains even if the first solvent is heated to the same temperature. That is, even if the first solvent having a high acid ratio is heated to the same temperature as the first solvent having a low acid ratio, the amount of heat contained per unit volume is small. Therefore, in order for the first solvent with a high acid ratio to supply heat per hour required by the chamber 110, it must be introduced into the chamber 110 at a higher flow rate than the first solvent with a low acid ratio, To this end, the degree of opening of the first valve 141 should be greater than in the case of the first solvent having a low acid ratio.

Hereinafter, the control operation of the first valve 141 and the second valve 151 performed by the server will be described.

First, the server 180 may define a distilled water-solvent specific heat capacity index (410).

The distilled water-solvent specific heat capacity index may be a value between 0 and 1. The distilled water-solvent specific heat capacity index of distilled water may be zero. As the ratio of the acid contained in the solvent increases, the distilled water-solvent specific heat capacity index of the solvent may be large.

Next, the server 180 may obtain the type of acid of the first solvent and a mixing ratio of water and acid (420).

The server 180 may pre-database the specific heat capacity of the acid according to the type of acid. The server 180 may pre-database data obtained by measuring the specific heat capacity of the solvent according to the mixing ratio of water and acid for each acid. The server 180 may refer to the type of acid of the first solvent and the mixing ratio of water and acid in the database.

Subsequently, the server 180 may calculate the distilled water-solvent specific heat capacity index of the first solvent (430).

The server 180 may calculate a distilled water-solvent specific heat capacity index close to 1 as the specific heat capacity of the acid included in the first solvent is relatively low or the ratio of the acid included in the first solvent is relatively high. . In addition, the server 180 calculates a distilled water-solvent specific heat capacity index close to zero as the specific heat capacity of the acid contained in the first solvent is relatively high or the ratio of the acid contained in the first solvent is relatively low. I can.

In the following order, the server 180 may adjust the degree of opening of the first valve and the second valve (440).

Specifically, the server 180 may adjust the degree of opening of the first valve 141 based on the distilled water-solvent specific heat capacity index of the first solvent so that the hard coating solution is prepared according to a predefined recipe. In addition, the server 180 adjusts the degree of opening of the second valve 151 based on the distilled water-solvent specific heat capacity index of the first solvent so that the gaseous risk level of the hard coating solution manufacturing apparatus 100 does not exceed the maximum level. I can.

Meanwhile, a specific value of the degree of opening of the first valve 141 and the second valve 151 may be determined based on inference of the artificial neural network. The detailed learning process of the artificial neural network will be described later with reference to FIG. 6.

Through the above, the server 180 appropriately adjusts the heat per hour required by the chamber 110 in response to the type of acid of the first solvent of the hard coating liquid device 100 and the mixing ratio of water and acid. It is possible to control the hard coating liquid device 100 so as to supply it.

5 is a view for explaining a hard coating solution manufacturing process according to an embodiment.

Plastic lenses, which are lightweight and unbreakable, have a fatal flaw in that their surface is vulnerable to scratches. In order for plastic lenses to have a surface hardness close to that of glass, a coating technology using a hard coating solution is required. The manufacturing process of the hard coating solution may include the following.

The hard coating solution manufacturing process may be performed according to the recipe 500. The predefined hard coating solution preparation recipe may be a hard coating solution polycondensation process using a sol-gel reaction. In the sol-gel reaction, a catalyst and water are added to a metal alkoxide to induce a hydrolysis process and a condensation reaction to produce a binder solution. It is possible to impart hardness, adhesion, heat resistance, and the like of the coating liquid.

Raw materials and catalysts included in the polycondensation reaction of the hard coating solution include colloidal silica or titania, 3-Glycidoxypropyl trimethoxysilane, tetraethoxyorthosilicate, Distilled water, acid, etc. may be included. Solvents and additives for preparing the hard coating solution may include an aluminum chelate compound, methanol, butyl cellosolve, and other levelers.

Looking at the component ratio per 100g, Colloidal Silica or Titania is 30%, 3-Glycidoxypropyl trimethoxysilane is 30%, and Tetraethoxyorthosilicate is 5%, distilled water may be 10%, acid (Acid) may be 0.8%. The aluminum chelate compound may be 1%, methanol may be 13%, butyl cellosolve may be 10%, and other levelers may be 0.2%.

Colloidal Silica or Titania can function as a filler sol. 3-Glycidoxypropyl trimethoxysilane and tetraethoxyorthosilicate can be classified as silanes. Distilled water may be a catalyst. The acid can be acetic acid. Distilled water and acid can constitute the first solvent.

The aluminum chelate compound can function as a hardener. Methanol Silver and Butyl Cellosolve may be solvents. Other levelers may include siloxane series.

As described above, the server 180 may control the order, time, and ratio of the raw materials and catalysts required for manufacturing the hard coating solution into the chamber 110. The server 180 may control the hard coating solution manufacturing apparatus 100 to adjust the mixing time and reaction temperature of the manufacturing solution. The server 180 may control the hard coating solution manufacturing apparatus 100 to undergo filtration to remove impurities and secure a homogeneous solution. Through this, it is possible to prepare a hard coating solution that imparts abrasion/abrasion resistance to the lens, protects the surface of the lens, and improves transparency of the lens.

6 is a diagram illustrating learning of an artificial neural network according to an embodiment.

The artificial neural network may be a component included in the server 180 and may be learned through the server 180 or a separate learning device.

The artificial neural network receives the standard information of the hard coating liquid device, gas pressure and chemical constituents for each predefined unit, and the distilled water-solvent specific heat capacity index of the first solvent, and receives the first valve 141 and the second valve 151. ) Can be printed out.

Hereinafter, a process of learning an artificial neural network through a learning device will be described.

First, the learning device may acquire training data and a label (600).

For artificial neural network learning, the training device provides training data for the specification information of various hard coating liquid devices, gas pressure and chemical components by predefined units for each situation, and distilled water-solvent specific heat capacity index of solvents mixed with water and acid. It can be obtained as (training data). In addition, for each training data, the first valve 141 is configured to prepare a hard coating solution according to a predefined recipe, and prevent the gas danger level of the hard coating solution manufacturing apparatus 100 from exceeding the maximum level. And the degree of opening of the second valve 151 may be obtained as a label corresponding to each training data.

Now, the learning device may generate an input of an artificial neural network from the training data (610).

The learning device may use the training data as an input of the artificial neural network or may generate an input of the artificial neural network after undergoing a known process of removing unnecessary information from each training data.

Next, the learning device may apply the input to the artificial neural network (620).

The artificial neural network included in the server may be an artificial neural network that is learned according to supervised learning. The artificial neural network may be a convolutional neural network (CNN) or a recurrent neural network (RNN) structure suitable for training through supervised learning.

Subsequently, the learning device may obtain an output from the artificial neural network (630).

The output of the artificial neural network is the first valve 141 and the first valve according to the standard information of each chamber 110, the gas pressure and chemical constituents of each predefined unit, and the distilled water-solvent specific heat capacity index of the first solvent. 2 It may be an inference of the degree of opening of the valve 151. Specifically, when the standard information of the chamber 110 is larger or smaller than the standard standard, the artificial neural network has a gas pressure for each predefined unit and a large or small number of chemical constituents classified as hazardous gases, distilled water of the first solvent-solvent. By learning the pattern according to the case where the specific heat capacity is high or low, the hard coating solution is manufactured according to a predefined recipe, and the gas danger level of the hard coating solution manufacturing apparatus 100 does not exceed the highest level. 141) and the degree of opening of the second valve 151 may be output.

Thereafter, the learning device may compare the output and the label (640 ).

The process of comparing the output of the artificial neural network corresponding to the inference with the label corresponding to the correct answer may be performed by calculating a loss function. As the loss function, a known mean squared error (MSE), cross entropy error (CEE), etc. may be used. However, the present invention is not limited thereto, and loss functions used in various artificial neural network models may be used as long as a deviation, error, or difference between the output of the artificial neural network and the label can be measured.

Next, the learning device may optimize the artificial neural network based on the comparison value (650).

By updating the weight of the nodes of the artificial neural network so that the comparison value of the learning device becomes smaller, the output of the artificial neural network corresponding to the inference and the label corresponding to the correct answer can be gradually matched. Through this, the artificial neural network It can be optimized to output an inference close to the correct answer. Specifically, the learning apparatus may optimize the artificial neural network by repeating the process of resetting the weight of the artificial neural network so that the loss function corresponding to the comparison value approaches the estimated value of the minimum value. For the optimization of artificial neural networks, known backpropagation algorithms, stochastic gradient descent, and the like can be used. However, the present invention is not limited thereto, and a weight optimization algorithm used in various neural network models may be used.

The learning device can train an artificial neural network by repeating this process.

Through this, the learning device is based on the standard information of the chamber 110, gas pressure and chemical constituents for each predefined unit, and the distilled water of the first solvent-solvent specific heat capacity index, etc., the first valve 141 and An artificial neural network that outputs the degree of opening of the second valve 151 may be trained. The artificial neural network may be used to control the degree of opening of the first valve 141 and the second valve 151 with reference to FIGS. 3 and 4.
