Description

Technical Field

[0001] This disclosure relates to the field of glass production technology, and more specifically, to a liquid level control method, apparatus, controller, and readable storage medium. Background Technology

[0002] With the upgrading of high-end display products, panel manufacturers are placing higher demands on the quality of glass substrates used in organic light-emitting diode (OLED) and low-temperature polysilicon (LTPS) displays. This necessitates more refined operations and controls in the production process of flat panel display substrate glass.

[0003] In the production process of substrate glass for OLED and LTPS displays, the furnace process is mainly responsible for melting the batch materials into qualified molten glass for downstream production processes. The stability of the furnace process is crucial to the production of subsequent processes. Among them, the stability of the liquid level directly affects the stability of furnace feeding, and the stability of platinum channel discharge control and process also has an important impact on the surface defects of the product.

[0004] In related technologies, to maintain stable liquid levels, nuclear level gauges are typically used to monitor liquid level signals during glass production. The transmitter and receiver are positioned on opposite sides of the platinum channel level tube. Rays are emitted from the transmitter, and the liquid level is analyzed by measuring the attenuation of the rays at the receiver. However, during production, the high-temperature molten glass corrodes the platinum body, causing leakage. This leakage significantly affects the absorption capacity of the rays, leading to distorted liquid level readings. In this situation, if automatic level control continues, erroneous and significant adjustments to the feed rate can cause substantial changes in the actual liquid level within the furnace. This could lead to uncontrolled feed flow, increased product defects, and extremely adverse effects on the safe operation of the platinum channel, potentially even requiring production line shutdowns and modifications. Summary of the Invention

[0005] The purpose of this disclosure is to provide a liquid level control method, apparatus, controller, and readable storage medium to solve problems in the related art.

[0006] To achieve the above objectives, according to a first aspect of the present disclosure, a liquid level control method is provided, applied to a glass production system, comprising:

[0007] When glass liquid level distortion is detected, the actual output of the glass production system is obtained;

[0008] Based on the actual output and output coefficient, the target feed rate is obtained. The output coefficient represents the ratio of the output to the feed rate of the glass production system when the glass liquid level is normal.

[0009] The actual feeding amount of the glass production system is obtained, and the feeding deviation value is obtained based on the target feeding amount and the actual feeding amount;

[0010] Based on the feeding deviation value and the actual feeding amount, the actual feeding amount for the next feeding is adjusted to maintain a stable liquid level during the glass production process.

[0011] Optionally, the method further includes:

[0013] The total value of the feeding deviation is compared with the preset deviation range to obtain the comparison result;

[0014] When the total value of the feeding deviation is within the preset deviation range, a feeding signal is generated and sent to the glass production system to perform the next feeding action.

[0015] Optionally, the method further includes:

[0016] When the total value of the feeding deviation is not within the preset deviation range, an alarm signal is generated and sent to the glass production system to stop the glass production system from operating.

[0017] Optionally, the method further includes:

[0018] The feeding deviation value is determined based on the first time period;

[0019] The determined feeding deviation values ​​are accumulated according to the second time period to obtain the sum of the first feeding deviation values, and the second time period is greater than the first time period;

[0020] The sum of the first feeding deviation values ​​determined each time is accumulated according to the third time period to obtain the second feeding deviation value, wherein the third time period is greater than the second time period;

[0021] The step of adjusting the actual feeding amount for the next feeding based on the feeding deviation value and the actual feeding amount includes:

[0022] With the feeding deviation value being within a first preset value range, the sum of the first feeding deviation values ​​being within a second preset value range, and the sum of the second feeding deviation values ​​being within a third preset value range as the target, the actual feeding amount for the next feeding is adjusted based on the feeding deviation value and the actual feeding amount, wherein the first preset value range is within the second preset value range, and the second preset value range is within the third preset value range.

[0023] Optionally, the formula for calculating the target feed amount is:

[0024] A1 = B1 / K;

[0025] Wherein, A1 is the target feeding amount, B1 is the actual output amount, and K is the output coefficient.

[0026] Optionally, the formula for calculating the feeding deviation value is:

[0027] △A = A' - A1;

[0028] Wherein, △A is the feeding deviation value, A' is the actual feeding amount, and A1 is the target feeding amount.

[0029] According to a second aspect of the present disclosure, a liquid level control device is provided, applied in a glass production system, the device comprising:

[0030] The output quantity acquisition module is used to acquire the actual output quantity of the glass production system when glass liquid level distortion is detected.

[0031] The target feeding amount generation module is used to obtain the target feeding amount based on the actual output amount and the output coefficient, wherein the output coefficient represents the ratio of the output amount to the feeding amount of the glass production system when the glass liquid level is normal.

[0032] The deviation value generation module is used to obtain the actual feeding amount of the glass production system, and to obtain the feeding deviation value based on the target feeding amount and the actual feeding amount;

[0033] The actual feeding amount generation module is used to adjust the next actual feeding amount based on the feeding deviation value and the actual feeding amount, so as to maintain the stability of the liquid level in the glass production process.

[0034] Optionally, the device further includes:

[0035] The total deviation value generation module is used to calculate the feeding deviation value for each feeding, and then accumulate them to obtain the total feeding deviation value.

[0036] The comparison module is used to compare the total value of the feeding deviation with a preset deviation range to obtain the comparison result;

[0037] The feeding module is used to generate a feeding signal and send it to the glass production system to perform the next feeding action when the total feeding deviation is within the preset deviation range.

[0038] According to a third aspect of the present disclosure, a controller is provided, comprising:

[0039] A memory on which computer programs are stored;

[0040] A processor is configured to execute the computer program in the memory to implement the steps of the liquid level control method provided in the first aspect of this disclosure.

[0041] According to a fourth aspect of the present disclosure, a non-transitory computer-readable storage medium is provided, on which a computer program is stored, which, when executed by a processor, implements the steps of the liquid level control method provided in the first aspect of the present disclosure.

[0042] The above technical solution allows for the following steps: When glass level distortion is detected, the actual output of the glass production system is obtained. Based on the actual output and the output coefficient, a target feed rate is calculated. The output coefficient represents the ratio of the output to the feed rate of the glass production system when the glass level is normal. The actual feed rate of the glass production system is then obtained, and a feed deviation value is calculated based on the target feed rate and the actual feed rate. Based on the feed deviation value and the actual feed rate, the next actual feed rate is adjusted to maintain a stable liquid level during glass production. In this way, when glass level distortion occurs, the target feed rate is obtained based on the actual output and the output coefficient representing a normal glass level. The next actual feed rate is then adjusted based on the target feed rate and the actual feed rate to avoid significant changes in the liquid level, thereby ensuring a stable liquid level during glass production.

Detailed Implementation

[0055] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0056] The terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not imply any order or importance. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements.

[0057] Before introducing the specific embodiments of this disclosure, the application scenario of this disclosure will first be explained. In the substrate glass production process, an important factor affecting the quality of the substrate glass is the stability control of the glass liquid level in the furnace and channels. Fluctuations in the glass liquid level in the furnace and channels can lead to defects such as bubbles, streaks, bright lines, and particles in the substrate glass, reducing the production yield of the production line.

[0058] In glass production systems, such as Figure 1As shown, the glass production system includes a feeding system 11, a furnace 12, a channel 13, a forming module 14, and a substrate glass output metering system 15. The feeding system 11 is equipped with an online glass powder weighing system for the furnace 12, and also has a hopper. Glass powder is added to the hopper through a material bag. The feeding system 11 is connected to the furnace 12, which is connected to the forming module 14 via the channel 13. The forming module 14 processes the molten glass to obtain substrate glass. The substrate glass output metering system 15 is connected to the rear end of the glass cutting device in the forming module 14 to record the production quantity of substrate glass.

[0059] like Figure 2 As shown, the platinum channel insulation layer 3, the platinum channel body 4, and the level tube 5 together constitute channel 13. The working principle of the nuclear level gauge used for level monitoring is as follows: The level gauge transmitter 1 and the level gauge receiver 2 are respectively placed on both sides of channel 13. Rays are emitted from the level gauge transmitter 1. After passing through channel 13 and the molten glass inside channel 13, the rays reach the level gauge receiver 2. The change in molten glass level is analyzed by analyzing the attenuation of the rays. During the production process, the high-temperature molten glass corrodes the platinum body, causing leakage. The molten glass leaking from the level tube 5 significantly affects the absorption capacity of the rays, resulting in distortion of the displayed level. Figure 3 As shown in the figure, the area between the two parallel horizontal lines is the liquid level control range, and the other changing line is the trend line. When the glass liquid level is within the liquid level control index, it indicates that the liquid level is normal. When the glass liquid level increases continuously in a short period of time and exceeds the liquid level control range, it indicates that the liquid level is distorted.

[0060] Liquid level monitoring typically uses nuclear level gauges. During production, the high-temperature molten glass corrodes the platinum body, causing leakage and resulting in abnormal readings from the nuclear level gauge. This leads to a significant deviation between the displayed liquid level and the actual liquid level. If liquid level control is still based on the displayed liquid level, the actual liquid level will deviate significantly from the normal production level, causing process abnormalities in kiln 12 and channel 13, resulting in a surge in board defects. In severe cases, this could lead to production line shutdown.

[0061] To address the aforementioned issues, this disclosure provides a liquid level control method. When the liquid level display is abnormal or distorted, the method can ignore the displayed liquid level value, accurately calculate the target feeding amount based on the actual output, and control the liquid level by using the difference between the target feeding amount and the actual feeding amount. This ensures that the liquid level in the kiln 12 and channel 13 remains relatively stable near the normal production level, maximizing the lifespan of the production line and enabling it to release maximum capacity within the production cycle, thereby guaranteeing economic benefits.

[0062] Based on the glass production system described above, the following is a possible implementation of the liquid level control method. Please refer to [link / reference]. Figure 4 , Figure 4 This is a flowchart of a liquid level control method provided in an embodiment of this disclosure. The liquid level control method may include the following steps:

[0063] Step S101: When glass liquid level distortion is detected, the actual output of the glass production system is obtained.

[0064] The output quantity can be the number of substrate glass produced as recorded at the end of the glass production system, and its unit can be a sheet or a piece. When the nuclear level gauge detects that the glass liquid level increases continuously in a short period of time and exceeds the liquid level control range, the glass liquid level is distorted. In this case, the production quantity of substrate glass in the glass production system is obtained, which is the actual output quantity.

[0065] Step S102: Based on the actual discharge rate and discharge coefficient, the target feed rate is obtained. The discharge coefficient represents the ratio of the discharge rate to the feed rate of the glass production system when the glass liquid level is normal.

[0066] The feed rate can be the weight of raw materials (e.g., glass powder) for glass production fed into the furnace 12 by the feeding system 11. The feeding system 11 is equipped with an online weighing system for glass powder in the furnace 12 to record the weight of the raw materials. The discharge coefficient characterizes the ratio of the discharge rate to the feed rate of the glass production system when the glass liquid level is within the controlled range. It should be noted that the discharge coefficient is a statistical measure of the ratio of the discharge rate to the feed rate of the glass production system over a period of time. This period can be half an hour, one hour, or other timeframes.

[0067] Furthermore, to ensure a more accurate discharge coefficient, the average daily hourly discharge rate and average daily hourly feed rate data for several consecutive days (e.g., 15 days) when the glass liquid level is normal can be obtained. The discharge coefficient can be calculated by the ratio of the two, which can further ensure the accuracy of the discharge coefficient.

[0068] The target feed rate can be the theoretical weight of glass production raw materials that should be fed into furnace 12, based on the existing actual output rate and the output coefficient when the glass liquid level is normal. The target feed rate can be derived by using the actual output rate and the output system.

[0069] Step S103: Obtain the actual feeding amount of the glass production system, and obtain the feeding deviation value based on the target feeding amount and the actual feeding amount.

[0070] The actual feed amount can be the weight of glass production raw materials actually fed into the furnace 12 within the aforementioned time period. The feed deviation value can be the difference between the actual feed amount and the target feed amount.

[0071] Step S104: Adjust the actual feeding amount for the next feeding based on the feeding deviation value and the actual feeding amount to maintain a stable liquid level during the glass production process.

[0072] When the feeding deviation value is positive, it indicates that too much material was added in the actual feeding behavior during that period, so an adaptive reduction is needed in the next actual feeding.

[0073] When the feeding deviation value is negative, it indicates that less material was added in the actual feeding behavior during that period, so an adaptive increase is needed in the next actual feeding.

[0074] In this way, when the glass liquid level is distorted, the target feeding amount is obtained based on the actual discharge amount and the discharge coefficient that characterizes the normal glass liquid level. The actual feeding amount is then adjusted according to the target feeding amount and the actual feeding amount to avoid large changes in the liquid level and thus ensure the stability of the liquid level during the glass production process.

[0075] Figure 5 This is a flowchart of another liquid level control method provided in an embodiment of this disclosure. For example... Figure 5 As shown, the liquid level control method may include the following steps:

[0076] Step S201: When glass liquid level distortion is detected, the actual output of the glass production system is obtained.

[0077] It should be noted that the implementation process of step S201 is the same as... Figure 4 The implementation process of step S101 shown is similar, and will not be described in detail in this embodiment.

[0078] Step S202: Based on the actual output and output coefficient, the target feed rate is obtained. The output coefficient represents the ratio of the output to the feed rate of the glass production system when the glass liquid level is normal.

[0079] It should be noted that the implementation process of step S202 is the same as... Figure 4 The implementation process of step S102 shown is similar, and will not be described in detail in this embodiment.

[0080] Step S203: Obtain the actual feeding amount of the glass production system, and obtain the feeding deviation value based on the target feeding amount and the actual feeding amount.

[0081] It should be noted that the implementation process of step S203 is the same as... Figure 4 The implementation process of step S103 shown is similar, and will not be described in detail in this embodiment.

[0082] Step S204: Adjust the actual feeding amount for the next feeding based on the feeding deviation value and the actual feeding amount to maintain a stable liquid level during the glass production process.

[0083] It should be noted that the implementation process of step S204 is the same as... Figure 4 The implementation process of step S104 shown is similar, and will not be described in detail in this embodiment.

[0084] Step S205: Calculate the feeding deviation value for each feeding and sum them up to obtain the total feeding deviation value.

[0085] Step S206: Compare the total value of the feeding deviation with the preset deviation range to obtain the comparison result.

[0086] Step S207: When the total value of the feeding deviation is within the preset deviation range, a feeding signal is generated and sent to the glass production system to perform the next feeding action.

[0087] The feeding signal can be a trigger signal to execute the feeding action. The feeding signal, combined with the specific feeding amount, enables the feeding action. The preset deviation range is set according to actual needs, for example, -10kg to 10kg. When the total feeding deviation is within the preset deviation range, step S207 is executed; otherwise, step S208 is executed.

[0088] Step S208: When the total value of the feeding deviation is not within the preset deviation range, an alarm signal is generated and sent to the glass production system to stop the glass production system from operating.

[0089] An alarm signal can be a trigger signal to terminate the feeding action. Once the glass production system receives an alarm signal, it will stop glass production.

[0090] It should be noted that steps S205 to S207 are the process of generating the feeding signal, and step S204 is the process of determining the actual feeding amount for the next feeding. The combination of the two allows the next feeding action to be performed. Steps S205 to S207 can be performed after step S204. In other embodiments, steps S205 to S207 can also be performed before step S204, or steps S205 to S207 and step S204 can be performed simultaneously. This embodiment does not impose any limitations on this.

[0091] By comparing a preset deviation range with the total feeding deviation, a feeding signal is generated when the total feeding deviation falls within the preset range, and an alarm signal is generated when the total feeding deviation falls outside the preset range. This comprehensive control of the feeding action maintains the stability of the molten glass surface.

[0092] Figure 6 A flowchart of another liquid level control method provided in this disclosure embodiment. (See flowchart for example.) Figure 6 As shown, the liquid level control method may include the following steps:

[0093] Step S31: When glass liquid level distortion is detected, obtain the actual output of the glass production system.

[0094] It should be noted that the implementation process of step S301 is the same as... Figure 4 The implementation process of step S101 shown is similar, and will not be described in detail in this embodiment.

[0095] Step S302: Based on the actual discharge rate and discharge coefficient, the target feed rate is obtained. The discharge coefficient represents the ratio of the discharge rate to the feed rate of the glass production system when the glass liquid level is normal.

[0096] It should be noted that the implementation process of step S302 is the same as... Figure 4 The implementation process of step S102 shown is similar, and will not be described in detail in this embodiment.

[0097] Step S303: Obtain the actual feeding amount of the glass production system, and obtain the feeding deviation value based on the target feeding amount and the actual feeding amount.

[0098] It should be noted that the implementation process of step S303 is the same as... Figure 4 The implementation process of step S103 shown is similar, and will not be described in detail in this embodiment.

[0099] Step S304: Determine the feeding deviation value based on the first time period.

[0100] Step S305: The determined feeding deviation values ​​for each feeding are accumulated according to the second time period to obtain the sum of the first feeding deviation values. The second time period is greater than the first time period.

[0101] Step S306: The sum of the first feeding deviation values ​​determined each time is accumulated according to the third time period to obtain the sum of the second feeding deviation values. The third time period is greater than the second time period.

[0102] The feeding deviation value is determined within the first time period, which corresponds to the aforementioned time period. The first time period is shorter than the second time period, and the second time period is shorter than the third time period. For example, the first time period can be an hour, the second time period can be a day, and the third time period can be a month. There are multiple second time periods within the third time period, and multiple first time periods within the second time period.

[0103] The sum of the first feeding deviation values ​​can represent the cumulative value of all determined feeding deviation values ​​within the second time period. The sum of the second feeding deviation values ​​can represent the cumulative value of the sum of all determined first feeding deviation values ​​within the third time period, or it can be the cumulative value of all determined feeding deviation values ​​within the third time period.

[0104] Step S307: With the goal of the feeding deviation value being within the first preset value range, the sum of the first feeding deviation values ​​being within the second preset value range, and the sum of the second feeding deviation values ​​being within the third preset value range, the actual feeding amount for the next feeding is adjusted based on the feeding deviation value and the actual feeding amount. The first preset value range is within the second preset value range, and the second preset value range is within the third preset value range.

[0105] The feeding deviation values ​​for the first time period, the sum of the first feeding deviation values ​​for the second time period, and the sum of the second feeding deviation values ​​for the third time period are each limited to a first preset value range, a second preset value range, and a third preset value range, respectively. The first preset value range is within the second preset value range, and the second preset value range is within the third preset value range. For example, if the first time period is an hour, the first preset value range could be -5kg to 5kg; if the second time period is a day, the second preset value range could be -10kg to 10kg; and if the third time period is a month, the third preset value range could be -50kg to 50kg.

[0106] Based on the feeding deviation value and the actual feeding amount, adjust the actual feeding amount for the next feeding. In addition to the first preset value range that should be considered for the feeding deviation value, the sum of the first feeding amount deviation value and the sum of the second feeding amount deviation value should also be taken into account in order to more comprehensively control the stability of the glass liquid level.

[0107] In one possible implementation, the target feed amount is calculated as follows:

[0108] A1 = B1 / K;

[0109] Where A1 is the target feed amount, B1 is the actual discharge amount, and K is the discharge coefficient.

[0110] In one possible implementation, the formula for calculating the feeding deviation value is:

[0111] △A = A' - A1;

[0112] Where △A is the feeding deviation value, A' is the actual feeding amount, and A1 is the target feeding amount.

[0113] To implement the above-described method embodiments, this embodiment provides a liquid level control device 400, such as... Figure 7 As shown, Figure 7 This is a block diagram of a liquid level control device 400 provided in an embodiment of the present disclosure. The liquid level control device 400 may include a discharge amount acquisition module 401, a target feed amount generation module 402, a deviation value generation module 403, and an actual feed amount generation module 404.

[0114] The discharge quantity acquisition module 401 is used to acquire the actual discharge quantity of the glass production system when glass liquid level distortion is detected.

[0115] The target feeding amount generation module 402 is used to obtain the target feeding amount based on the actual output amount and the output coefficient. The output coefficient represents the ratio of the output amount to the feeding amount of the glass production system when the glass liquid level is normal.

[0116] The deviation value generation module 403 is used to obtain the actual feeding amount of the glass production system and to obtain the feeding deviation value based on the target feeding amount and the actual feeding amount.

[0117] The actual feeding amount generation module 404 is used to adjust the next actual feeding amount based on the feeding deviation value and the actual feeding amount in order to maintain the stability of the liquid level during the glass production process.

[0118] Optionally, the level control device 400 further includes:

[0119] The total deviation value generation module is used to calculate the feeding deviation value for each feeding, and then accumulate them to obtain the total feeding deviation value.

[0120] The comparison module is used to compare the total value of the feeding deviation with the preset deviation range to obtain the comparison result;

[0121] The feeding module is used to generate a feeding signal and send it to the glass production system to perform the next feeding action when the total feeding deviation is within the preset deviation range.

[0122] Optionally, the level control device 400 also includes an alarm module.

[0123] The alarm module is used to generate an alarm signal and send it to the glass production system when the total deviation value of the material feeding is not within the preset deviation range, so that the glass production system stops operating.

[0124] Optionally, the level control device 400 further includes:

[0125] The first cycle deviation value determination module determines the feeding deviation value based on the first time cycle;

[0126] The second cycle deviation value determination module accumulates the determined feeding deviation value for each time according to the second time cycle to obtain the sum of the first feeding deviation value. The second time cycle is greater than the first time cycle.

[0127] The third cycle deviation value determination module accumulates the sum of the first feeding deviation values ​​determined each time according to the third time cycle to obtain the sum of the second feeding deviation values. The third time cycle is greater than the second time cycle.

[0128] The actual feed amount generation module 404 is specifically used for:

[0129] With the goal of the feeding deviation value being within the first preset value range, the sum of the first feeding deviation values ​​being within the second preset value range, and the sum of the second feeding deviation values ​​being within the third preset value range, the actual feeding amount for the next feeding is adjusted based on the feeding deviation value and the actual feeding amount. The first preset value range is within the second preset value range, and the second preset value range is within the third preset value range.

[0130] Optionally, the formula for calculating the target feed amount is:

[0131] A1 = B1 / K;

[0132] Wherein, A1 is the target feeding amount, B1 is the actual output amount, and K is the output coefficient.

[0133] Optionally, the formula for calculating the feeding deviation value is:

[0134] △A = A' - A1;

[0135] Wherein, △A is the feeding deviation value, A' is the actual feeding amount, and A1 is the target feeding amount.
