[0027] In the glass manufacturing industry, optical glass production has almost stringent requirements on product quality due to its key applications in many high-tech fields. From precision optical instruments to high-end electronic equipment displays, the performance stability and uniformity of optical glass directly determine the quality and performance of the end product. In this complex production process, liquid level control is a crucial part of the glass melting process. It is like a precise hub in the production chain. The stability of the liquid level is directly related to the quality of the product.

[0028] Liquid level control is a typical complex control object in the field of industrial control. On the one hand, it widely involves multiple industrial control levels, covering multiple links from physical sensor measurement to logical control algorithm execution. On the other hand, liquid level control has the characteristics of high nonlinearity and hysteresis. Its nonlinearity is manifested in that the liquid level change and the control input are not a simple proportional relationship, but are affected by the interaction of multiple complex factors, such as the flow characteristics of glass liquid and the uneven temperature distribution inside the furnace. Hysteresis means that after the control action is implemented, there is a certain time delay in the response of the liquid level, which further increases the difficulty of control. Conventional PID control methods, although they perform well in many linear control systems, often find it difficult to achieve ideal control effects when faced with these complex characteristics of liquid level control.

[0029] At present, the industry generally adopts a control method based on manual smelting experience. This method places high demands on the professional quality and practical experience of employees. Operators need to rely on their long-term accumulated experience to judge the liquid level status and make manual adjustments. However, manual control has many inherent defects. Operators are prone to fatigue during long-term continuous monitoring and adjustment, which not only leads to excessive labor intensity, but also seriously affects the consistency and accuracy of control. At the same time, the experience of different operators varies significantly, which makes the control effect uneven and it is difficult to ensure the accuracy and stability of liquid level control. In the context of modern industrial production emphasizing high efficiency, stability and high precision, this manual control method obviously cannot meet production needs.

[0030] In summary, how to improve the stability of liquid level control and ensure that the liquid level remains accurate and stable during the glass melting process, thereby ensuring the high-quality production of optical glass products, has become a key issue that needs to be urgently solved in the glass manufacturing industry.

[0031] To this end, this application proposes a glass liquid level control method, which can be referred to Figure 1 , Figure 1 This is a process of the glass liquid level control method provided in the embodiment of the present application. The glass liquid level control method can be applied to any terminal device that can run a program.

[0032] The following, combined Figure 1 A glass liquid level control method according to an embodiment of the present application is described in detail.

[0033] Step S101: collecting the real-time liquid level height of the target pipeline, and calculating the real-time liquid level difference between the real-time liquid level height and the target liquid level height.

[0034] The target pipeline is a pipeline connecting the outlet of the melting tank and the feed port of the electric furnace clarification tank. For example, the target pipeline can be a MF tube, or a quartz glass tube or other special composite material pipeline. In practical applications, the target pipeline can be an ultra-high temperature (such as >1300°C) pipe pool for transmitting liquid glass. Optionally, the target pipeline can be divided into multiple sections according to the actual liquid level control requirements, and the liquid level of each section of the pipeline can be independently controlled by the glass liquid level control method proposed in this application.

[0035] For example, the real-time liquid level of the target pipeline is collected by a pre-installed laser sensor. The real-time liquid level measured at a certain moment is 548 mm, and the target liquid level is 550 mm. The real-time liquid level difference between the real-time liquid level and the target liquid level is calculated to be 2 mm.

[0036] This difference reflects the degree of deviation between the current liquid level and the target liquid level, and is one of the important bases for subsequent judgment of the liquid level status and temperature adjustment decisions. If the real-time liquid level difference is a positive value, it means that the liquid level is lower than the target liquid level; if it is a negative value, the liquid level is higher than the target liquid level; the absolute value of the difference reflects the degree of deviation, and the larger the absolute value, the more serious the deviation. Throughout the production process, the control system continuously repeats the above acquisition and calculation steps, continuously monitors the changes in the liquid level height, and provides real-time data support for subsequent liquid level control.

[0037] Step S102: obtaining a liquid level variation trend of a target pipeline within a preset period of time, where the liquid level variation trend is used to indicate a variation trend of a difference between an actual liquid level height and a target liquid level height.

[0038] Obtaining the liquid level change trend of the target pipeline within a preset period of time means analyzing the difference between the actual liquid level height and the target liquid level height within the preset period of time to determine the liquid level change trend. The liquid level change trend is used to indicate the change trend of the difference between the actual liquid level height and the target liquid level height. The liquid level change trend can be an increase or decrease.

[0039] It should be understood that the duration of the preset time period should be able to reflect the short-term change trend of the liquid level and should not be too long to cause a delayed response to the liquid level change.

[0040] In an optional embodiment, before obtaining the liquid level change trend of the target pipeline within a preset time period, the method also includes: obtaining multiple liquid level heights within the preset time period, the multiple liquid level heights are used to represent the liquid level heights at different times within the preset time period; respectively calculating multiple liquid level differences between the multiple liquid level heights and the target liquid level height; and determining the liquid level change trend according to the change pattern of the multiple liquid level differences over time.

[0041] When acquiring multiple liquid level heights within a preset time period, the terminal device regularly collects liquid level data points within the preset time period at a fixed time interval. For example, the fixed time interval is 10 seconds.

[0042] For example, the preset time period is the first 10 minutes of the time corresponding to the real-time liquid level height of the target pipeline. It is assumed that a total of 60 liquid level height values ​​are collected in the 10 minutes, and the liquid level collection cycle (10S) is recorded as H1, H2, H3...H60 respectively; and the target liquid level height is known to be 550mm. The liquid level difference between each liquid level height and the target liquid level height is calculated respectively, such as the first liquid level difference ΔH1=550-H1, the second liquid level difference ΔH2=550-H2, and so on, to obtain 60 liquid level differences ΔH1, ΔH2...ΔH60. With time as the independent variable x and the liquid level difference as the dependent variable y, 60 data points (x1, y1), (x2, y2)...(x60, y60) are constructed, and these data points are linearly fitted using the least squares method. The equation of the fitted line is y=kx+b. The slope k and intercept b of the line are calculated according to the least squares formula. The trend of liquid level change is determined based on the calculated slope k. When using the least squares method to fit the line y=kx+b, the sum of the distances from all data points to the line is minimized, and the distance is the error e. For each data point (x i ,y i )(x i is the collection time, y i is the liquid level difference), error e i =y i -(kx i +b), total error Solve for the parameters slope k and intercept b, Where n is the number of data points. According to the sum of natural numbers N: The sum of N squared natural numbers: Calculate when n = 60, S n =1830, S n and Substituting into the equations about k and b, we get 73810k+1830b=-10000 and 1830k+60b=-300, and solve for k=-0.02, b=5. Because k<0, the liquid level changes in the direction higher than the target liquid level and gradually approaches the target liquid level, that is, the liquid level shows an upward trend, and according to the absolute value of k, it can be known that the liquid level rises slowly. In this application, when the absolute value of k is greater than 0.03, it is considered that the liquid level is changing rapidly, and when it is less than 0.03, the liquid level changes slowly.

[0044] If k>0, it means that the liquid level difference increases with time, that is, the liquid level changes in the direction below the target liquid level and the deviation is getting bigger and bigger. It can be judged that the liquid level is showing a downward trend; the absolute value of k reflects the speed of liquid level change. The larger the absolute value, the faster the change.

[0045] In this embodiment, the liquid level difference reflects the deviation of the liquid level relative to the target liquid level at each moment, and the change pattern of these differences over time is analyzed to determine the liquid level change trend, so that the liquid level change trend can more accurately represent the dynamics of the liquid level change within the preset time period, providing a more reliable basis for determining the preset temperature adjustment value.

[0046] In an optional embodiment, before obtaining multiple liquid level coordinates within a preset time period, the method also includes: emitting multiple laser beams of different frequencies to the glass liquid level surface according to a preset acquisition cycle within the preset time period; receiving multiple laser signals reflected by the multiple laser beams; comparing the multiple laser signals with multiple preset reflection signals to obtain multiple phase differences formed by the multiple laser signals and the multiple preset reflection signals; and calculating multiple liquid level heights based on the multiple phase differences and the multiple frequencies corresponding to the multiple laser beams.

[0047] Before the laser sensor emits multiple laser beams of different frequencies to the glass liquid level surface, it can be equipped with a specially designed mounting bracket with adjustable angle and position functions. During installation, the technician will determine the appropriate installation height and angle through measurement and calculation based on the specific structure and size of the glass furnace or container, so that the laser beam can be directly pointed to the expected liquid level surface area; the laser sensor can also be equipped with aiming aids, such as optical sights or laser pointers. During the initial installation and debugging stage, the operator can use these aiming aids to adjust it to be precisely aligned with the liquid level surface, and this application does not make specific restrictions on this.

[0048] The preset reflection signal is a reflection signal measured in advance under a known standard liquid level height and the same transmission conditions.

[0049] Combined with the above example, the laser level meter emits multiple laser beams (3) of different frequencies to the glass liquid level surface every 10 seconds within 10 minutes. For example, the frequencies of the multiple laser beams are f1, f2, and f3, respectively. According to experience and accuracy requirements, the liquid level height values ​​corresponding to f1, f2, and f3 are respectively assigned weights w1, w2, and w3 (for example, w1=0.2, w2=0.3, and w3=0.5). At the same time, the receiving device of the laser level meter receives multiple laser signals reflected from the glass liquid level surface by these laser beams, and compares each received laser signal with the corresponding preset reflection signal, and calculates the phase difference Δφ1 (corresponding to f1), Δφ1 (corresponding to f2), and Δφ1 (corresponding to f3) formed between the received laser signal and the preset reflection signal; according to the laser phase comparison principle, the formula is used (Where L is the liquid level height, c is the speed of light, Δφ is the phase difference, and f is the laser frequency) Calculate the liquid level heights L1, L2, and L3 corresponding to each moment, then the liquid level height at each moment is L = L1×w1+L2×w2+L3×w3.

[0050] In this embodiment, based on the properties of the glass liquid level surface (such as high temperature and viscosity), laser beams of different frequencies are emitted and the liquid level height is calculated using the phase difference, so that highly accurate liquid level height data can be obtained, providing a reliable data source for determining the liquid level change trend.

[0051] Step S103: According to the change trend and the real-time liquid level difference, a corresponding preset temperature adjustment value is matched from the preset temperature adjustment strategy to adjust the temperature value of the target pipeline according to the preset temperature adjustment value.

[0052] The preset temperature adjustment strategy sets the corresponding preset temperature adjustment strategy for the combination of different liquid level difference ranges and liquid level change speeds (determined by the k value). The preset temperature adjustment strategy can be generated by combining relevant liquid level adjustment experience (such as expert experience) and standard set temperature adjustment strategies. For example, when the real-time liquid level difference is 1-3mm and the absolute value of k is less than 0.03, the preset temperature adjustment value is -0.5℃.

[0053] For example, after obtaining the real-time liquid level difference of 2 mm and parameter k=-0.02, since the absolute value of k is less than 0.03, it indicates that the liquid level changes slowly and is on an upward trend. Based on this information, a query and match is performed in the preset multiple temperature adjustment strategies. The matching result is that the preset temperature adjustment value is -0.5°C, then the temperature of the target pipeline is lowered by 0.5°C.

[0054] Since the temperature of the pipeline directly affects the viscosity of the liquid glass, thereby indirectly controlling the flow rate of the liquid glass, the present application proposes that by calculating the difference between the real-time liquid level height of the target pipeline and the target liquid level, combined with the analysis of the liquid level change trend within a preset time period, the change direction of the liquid level can be dynamically and meticulously grasped, and it can be predicted whether the liquid level is approaching or moving away from the target liquid level and the speed of the change. Based on this information, the target pipeline temperature can be adjusted in a more targeted and timely manner, thereby realizing dynamic regulation of the glass liquid level in the pipe pool, thereby improving the stability of the glass liquid level control.

[0055] In an optional embodiment, after matching a corresponding preset temperature adjustment value from a preset temperature adjustment strategy according to the change trend and the real-time liquid level difference to adjust the temperature value of the target pipeline according to the preset temperature adjustment value, the method also includes: obtaining a calibration temperature of the target pipeline, determining a glass liquid flow value corresponding to the target pipeline according to the calibration temperature, the calibration temperature being the temperature value at any time after the temperature value of the target pipeline is adjusted according to the preset temperature adjustment value; obtaining a calibration liquid level, judging a corrected liquid level trend corresponding to the calibration liquid level according to the glass liquid flow value, the calibration liquid level being the liquid level at any time after the temperature value of the target pipeline is adjusted according to the preset temperature adjustment value; matching a corresponding preset corrected temperature adjustment value from a preset temperature adjustment strategy according to the corrected liquid level trend and the calibration liquid level; calculating the preset corrected temperature adjustment value based on a preset weight value to obtain the corrected temperature adjustment value, so as to adjust the temperature value of the target pipeline again according to the corrected temperature adjustment value.

[0056] The calibration temperature is the temperature value at any time after the temperature value of the target pipe is adjusted according to the preset temperature adjustment value. Among them, the temperature value at any time can be 10 minutes after the temperature value of the target pipe is adjusted, or it can be 5 seconds, and the staff can set it according to actual needs. It is easy to understand that the calibration liquid level refers to the liquid level value collected at any time, which can be collected at the same time as the calibrated temperature, or it can be collected within the adjacent time range of the calibration temperature collection time, and this application does not make specific restrictions on this.

[0057] The preset weight value is set based on the relative importance of the pipeline in flow control. Assume that the pipeline connecting the melting pool outlet and the electric furnace clarifier inlet is divided into three sections, namely MF1, MF2, and MF3, where the weight of MF1 pipe is 50%, MF2 pipe is 30%, and MF3 pipe is 20%. The target pipeline can be any section of MF1, MF2, and MF3. If the pipeline connecting the melting pool outlet and the electric furnace clarifier inlet is not segmented, the target pipeline is the pipeline connecting the melting pool outlet and the electric furnace clarifier inlet, and the weight is 1.

[0058] Taking the target pipeline as MF1 as an example, the real-time temperature of MF1 obtained by the temperature sensor is 1075℃. It is known that the preset temperature adjustment value is -2℃, and the expected temperature value is 1075℃-2℃×50%=1074℃. According to the target pipeline characteristics and related formulas (flow Q∝K□T, K is the system constant determined by the target pipeline characteristics, and T is the MF tube temperature), the glass liquid flow value is calculated in combination with the preset weight value. For example, K=0.008, then the glass liquid flow value Q=0.008×1074=8.592m3 / h, and then the target pipeline temperature value is adjusted according to the corresponding relationship between the glass liquid flow value and the temperature adjustment strategy in the preset temperature adjustment strategy. For example, the glass liquid flow value is 8.592m3 / h, and the glass liquid flow value is compared with the actual pipeline flow value to determine the change in pipeline flow. If the liquid level height corresponding to the change still deviates from the target, the target pipeline temperature value is further adjusted, such as reducing it by 0.5℃ again.

[0059] In this embodiment, by introducing the calculation and analysis of the real-time temperature, the expected temperature value and the glass liquid flow value, the temperature can be adjusted more accurately according to the pipeline flow feedback, and the liquid level control effect can be further optimized.

[0060] In an optional embodiment, according to the change trend and the real-time liquid level difference, a corresponding preset temperature adjustment value is matched from a preset temperature adjustment strategy to adjust the temperature value of the target pipeline according to the preset temperature adjustment value, including: obtaining a first temperature value corresponding to the change trend, and matching the corresponding first temperature adjustment value from the preset temperature adjustment strategy; obtaining a second temperature value corresponding to the real-time liquid level difference, and matching the corresponding second temperature adjustment value from the preset temperature adjustment strategy; calculating the sum of the first temperature adjustment value and the second temperature adjustment value, and matching the corresponding third temperature adjustment value from the preset temperature adjustment strategy according to the calculation result; calculating the third temperature adjustment value based on a preset thermal inertia coefficient to obtain the target temperature correction value.

[0061] For example, after determining the liquid level change trend (such as slope k = 0.03, the liquid level shows a rapid upward trend) and the real-time liquid level difference (assuming 3mm), the first temperature value corresponding to the change trend is obtained. According to a large number of past experiments and production experience, under this rapid upward trend, the first temperature value is -1.5°C, which is intended to suppress the rapid rise of the liquid level. The first temperature adjustment value corresponding to -1.5°C is -1.1°C; and the second temperature value corresponding to the real-time liquid level difference of 3mm is obtained, which is -0.9°C. The second temperature adjustment value corresponding to -0.9°C is -1.3°C to compensate for the liquid level deviation; the sum of the first temperature adjustment value and the second temperature adjustment value is calculated to obtain the third temperature adjustment value, that is, -1.1+(-1.3)=-2.4°C. The target pipeline has thermal inertia, which will delay the temperature adjustment effect. Assuming that the preset thermal inertia coefficient is 0.8, it can be calculated that the preset temperature adjustment value is -2.4×0.8=-1.92°C, and the temperature of the target pipeline is adjusted accordingly.

[0062] In this implementation, the liquid level change trend and the real-time liquid level difference are split into corresponding temperature values, and then the preset temperature adjustment value is comprehensively calculated, taking into account the influence of pipeline thermal inertia, which can improve the accuracy and scientificity of temperature adjustment.

[0063] In an optional embodiment, before calculating the initial temperature adjustment value according to the preset thermal inertia coefficient and obtaining the preset temperature adjustment value, the method also includes: obtaining historical temperature adjustment data, the historical temperature adjustment data including temperature change data, liquid level change data, and environmental data; calculating change parameters according to the historical temperature adjustment data, the change parameters including temperature change amount, liquid level change amount, liquid level change time, ambient temperature, and humidity; and inputting the change parameters into a thermal inertia coefficient calculation function for calculation to obtain the preset thermal inertia coefficient.

[0064] The temperature change data includes the initial temperature, the adjusted temperature, and the time required to reach a stable liquid level each time the temperature is adjusted. For example, in one adjustment, the temperature change data includes an initial temperature of 1000°C, an adjusted temperature of 1020°C, and a time of 60 seconds from the start of temperature adjustment to liquid level stabilization.

[0065] The liquid level change data includes the liquid level change corresponding to the temperature change, including the initial value of the liquid level and the stable value after adjustment. For example, the liquid level change data includes the initial value of the liquid level 50CM and the stable value of the liquid level 52CM.

[0066] Environmental data includes relevant data in the production environment, such as ambient temperature, humidity, etc. Assume that the ambient temperature is 25°C and the humidity is Rh=50%.

[0067] Optionally, the thermal inertia coefficient calculation function is ΔT is the temperature change, ΔL is the liquid level change, t is the liquid level change time, Ta is the ambient temperature, and Rh is the humidity.

[0068] Exemplarily, based on the historical temperature adjustment data obtained, the temperature change ΔT (e.g., 1000°C-1020°C=20°C), the liquid level change ΔL (e.g., 50CM-52CM=2CM), the liquid level change time t (e.g., 60S), the ambient temperature Ta (e.g., 25°C), and the humidity Rh (e.g., 50%) are calculated, and the thermal inertia coefficient calculation function M is combined for calculation to obtain the preset thermal inertia coefficient.

[0069] In this embodiment, by calculating the thermal inertia coefficient by comprehensively considering the temperature, liquid level and environmental factors, the thermal inertia coefficient can be made to fit the current actual working conditions.

[0070] In an optional embodiment, before matching a corresponding preset temperature adjustment value from a preset temperature adjustment strategy based on the change trend and the real-time liquid level difference to adjust the temperature value of the target pipeline according to the preset temperature adjustment value, the method also includes: judging whether the liquid level change trend is within a reasonable change range through the preset temperature adjustment strategy; if it is within a reasonable change range, adjusting the temperature value of the target pipeline with the preset temperature adjustment value.

[0071] Combined with the above example, the liquid level change trend is 0.03. After obtaining the liquid level change trend of the target pipeline within the preset time period, it is determined whether the liquid level change trend of 0.03 is a safe change trend or a dangerous change trend. If it is a safe change trend, the preset temperature adjustment strategy also includes judging according to the liquid level change trend. If it is a dangerous change trend, an alarm signal is issued to instruct the staff to deal with the dangerous situation in time.

[0072] In this embodiment, by judging whether the liquid level change trend is within a reasonable range, temperature adjustment errors caused by excessively rapid liquid level changes can be effectively avoided, thereby avoiding unexpected situations caused by excessively rapid liquid level changes.

[0073] Optionally, after obtaining the calibration temperature of the target pipeline and determining the glass liquid flow value corresponding to the target pipeline according to the calibration temperature, the method also includes: calculating the flow difference between the estimated pipeline flow value and the real-time pipeline flow value; judging whether the flow difference is within a reasonable range of variation, and if so, adjusting the temperature value of the target pipeline according to the temperature adjustment policy corresponding to the estimated pipeline flow value.

[0074] For example, after obtaining the glass liquid flow value, the real-time pipeline flow value of the target pipeline is obtained by using an electromagnetic flowmeter. Assuming that the glass liquid flow value is 8m 3 / h, the real-time pipeline flow rate is 7.8m 3 / h, the flow difference is 8-7.8=0.2m 3 / h. Pre-set a reasonable range of change, such as ±0.3m 3 / h, due to 0.2m 3 / h is within the reasonable range of variation, so it is determined that the temperature value of the target pipeline can be adjusted according to the preset temperature adjustment value corresponding to the glass liquid flow value. If the flow difference exceeds this range, it is considered that the temperature adjustment amplitude is too large, and it is necessary to re-determine the preset temperature adjustment value, and then calculate the new flow difference corresponding to the newly determined preset temperature adjustment value to determine whether the new flow difference is reasonable. If not, continue to adjust the preset temperature adjustment value.

[0075] In this embodiment, by calculating the difference between the glass liquid flow value and the real-time pipeline flow value and judging whether it is within a reasonable range, the accuracy of the estimated flow can be effectively verified to avoid temperature adjustment errors caused by excessive estimation deviation.

[0076] In order to better understand the solution proposed in this application, this application is illustrated with practical application scenarios. Figure 2 The contents shown include melting pool, laser level meter, linkage control box, level difference calculation, temperature control cabinet, connecting pipes 1, 2, 3..., HMI human-machine interface, clarification tank, etc. The following is a detailed description of each part

[0077] Melting pool: This is the starting point of glass melting, where glass raw materials are melted to form liquid glass. For example, a variety of raw materials are put into the melting pool in a certain proportion, gradually melted into liquid under high temperature environment, and provide glass liquid for subsequent processes.

[0078] Liquid level acquisition: The laser level meter is set near the melting pool to collect liquid level information. It works in a preset manner, for example, within 10 minutes, it emits laser beams of different frequencies (such as 3 beams of different frequencies) to the glass liquid level surface every 10 seconds. Assuming that the frequencies of these beams are f1=100Hz, f2=200Hz, and f3=300Hz, respectively, according to experience and accuracy requirements, the corresponding liquid level height values ​​are assigned weights w1=0.2, w2=0.3, and w3=0.5. The laser level meter receives multiple laser signals reflected from the glass liquid level surface by these laser beams, compares each received laser signal with the corresponding preset reflection signal, and calculates the phase difference formed with the preset reflection signal. According to the laser phase comparison principle and related formulas, the liquid level heights L1, L2, and L3 corresponding to each moment are calculated, and finally the liquid level height at each moment is L=L1×w1+L2×w2+L3×w3.

[0079] Liquid level difference calculation: Assuming the target liquid level is 550mm, the multiple liquid level values ​​collected by the laser level meter are H1=548mm, H2=549mm, H3=549.5mm, etc. Then calculate the first liquid level difference ΔH1=550-H1=2mm, the second liquid level difference ΔH2=550-H2=1mm, the third liquid level difference ΔH3=550-H3=0.5mm, etc.

[0080] Determine the trend of liquid level change: Take time as the independent variable x, and the liquid level difference as the dependent variable y, and construct multiple data points (x1, y1), (x2, y2), (x3, y3), etc., such as (10s, 2mm), (20s, 1mm), (30s, 0.5mm). Use the least squares method to perform linear fitting on these data points, and set the equation of the fitting line to y=kx+b. Calculate the slope k and intercept b of the line according to the least squares formula. Assume that the calculation results in k=-0.02, b=5. Because k<0, the liquid level changes in the direction higher than the target liquid level and gradually approaches the target liquid level, that is, the liquid level shows an upward trend, and according to the absolute value of the slope, it can be seen that the liquid level rises slowly.

[0081] Formulation of temperature adjustment strategy: The linkage control box matches the corresponding preset temperature adjustment value from the preset temperature adjustment strategy according to the liquid level change trend and the liquid level difference. The preset temperature adjustment strategy sets the corresponding preset temperature adjustment strategy for the combination of different liquid level difference ranges and liquid level change speeds (determined by the k value). For example, when the real-time liquid level difference is 1-3mm and the absolute value of k is less than 0.03, the preset temperature adjustment value is -0.5℃. In the above example, the real-time liquid level difference is 2mm, 1mm, 0.5mm, etc., k=-0.3, which meets the conditions, so based on this information, a query is performed in the preset multiple temperature adjustment strategies, and the matching result is that the preset temperature adjustment value is -0.5℃.

[0082] Temperature control cabinet: Controls the temperature of the connecting pipe according to the instructions of the linkage control box. For example, if the linkage control box determines that the temperature of the connecting pipe needs to be lowered by 0.5°C, the temperature control cabinet will perform the corresponding operation to lower the temperature of the pipe. By adjusting the temperature, the viscosity of the liquid glass can be changed, thereby affecting the flow rate and liquid level of the glass liquid. Assuming that the initial temperature of the connecting pipe is 1000°C, it will be lowered by 0.5°C to 999.5°C. The viscosity of the glass liquid will increase accordingly, thereby affecting its flow rate and liquid level in the connecting pipe.

[0083] Connecting pipes 1, 2, 3…: used to transport liquid glass and connect melting tanks, clarification tanks and other related equipment.

[0084] HMI: It provides an interface for operators to interact with the system. Operators can view the operating status of the system, such as liquid level, temperature, etc., through this interface, and can also set and adjust some parameters. For example, operators can view the current liquid level as 549.5mm and the connection pipe temperature as 999.5℃ on the HMI interface, and can also modify parameters such as the target liquid level and temperature adjustment strategy according to actual conditions.

[0085] Clarifier: Liquid glass enters the clarifier from the melting tank through the connecting pipe, where it undergoes further clarification to make the glass liquid purer. For example, some physical or chemical methods are used in the clarifier to remove impurities in the glass liquid and improve the quality of the glass.

[0086] Glass liquid flow: represents the flow path of liquid glass in the system, starting from the melting pool, passing through the connecting pipe, entering the clarification pool, and finally being used for discharging and molding. It intuitively shows the transmission process of glass liquid in the entire system.

[0087] Heating control: Associated with the temperature control cabinet, it is responsible for controlling the various parts that need to be heated (such as connecting pipes, melting pools and other existing heating equipment) to ensure that the temperature meets the process requirements. For example, the heating control will heat or stop heating the connecting pipe according to the instructions of the temperature control cabinet to maintain its temperature within the appropriate range.

[0088] Discharging and molding: It is the last link in glass production. After a series of previous treatments, the liquid glass is processed into the final product shape here. For example, liquid glass is poured into a mold and cooled to form a glass product of a specific shape, such as a lens, a glass tube, etc.
