DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0020] Reference Figure 1 The first embodiment of the present invention provides an energy-saving control method for optical fiber production equipment, comprising the following steps: S11, acquiring process condition data; wherein the process condition data includes single-mode process condition data, multi-mode process condition data and special material process condition data; S12, inputting the process condition data into an energy consumption calculation formula to calculate and obtain the optical fiber process energy consumption; S13, obtaining the initial energy consumption per unit time, initial output per unit time, and equipment parameters of each process; S14, inputting the optical fiber process energy consumption and the initial energy consumption per unit time into a yield calculation formula for calculation to obtain the optical fiber process yield; S15, performing a construction operation according to the equipment parameters and the optical fiber process energy consumption to obtain an energy consumption relationship model; S16, performing a construction operation according to the energy consumption relationship model and the optical fiber process output to obtain a standard energy consumption and output relationship model; S17, calculating according to the standard energy consumption-output relationship model to obtain a start-stop time sequence of the equipment; S18, determining the optimal energy-saving control strategy according to the equipment start-stop time sequence, and inputting it into the controller to control the start-stop of the equipment.
[0021] In step S11, process condition data is acquired; wherein the process condition data includes single-mode process condition data, multi-mode process condition data and special material process condition data.
[0022] Single-mode process condition data includes various process parameters and conditions required for single-mode optical fiber production, including the data required for rod grinding, pickling, rough drawing, medium drawing, fine drawing, core loading and other processes. For example, single-mode optical fiber light rod temperature, drawing speed, air pressure and other parameters are all single-mode process condition data. Multi-mode process condition data refers to the process parameters and conditions required for the production process of multi-mode optical fiber. Compared with single-mode process, multi-mode process has more variables and settings, and requires more complex control and monitoring. For example, multi-mode optical fiber has different diameter requirements, and optical fibers of different diameters have different processing processes. Therefore, in the production process, the specific process condition data of optical fibers of different diameters are recorded in detail, which are used as parameters for calculation in subsequent steps. Special material process condition data refers to the unique process parameters and conditions required for the preparation of optical fibers from special materials. These unique process parameters and conditions involve the chemical composition, structural design, processing technology and other aspects of special materials, such as parameters such as dopant concentration, material structure, and solution ratio. During the production process, sensors and monitoring equipment are needed to collect process condition data in real time and record the data. By monitoring and analyzing the process condition data, abnormal situations in the production process can be discovered in time, and improvements can be made based on the analysis of historical process condition data, thereby reducing energy consumption.
[0023] In step S12, the process condition data is input into an energy consumption calculation formula to obtain the optical fiber process energy consumption.
[0024] In one implementation, the optical fiber process energy consumption is calculated as follows: M1 = T1 * t1 + v1 + v2 + v3 Among them, M1 represents the fiber process energy consumption, T1 represents the fiber light rod temperature, t1 represents the fiber light rod temperature time, v1 represents the rod grinding time, v2 represents the polishing speed, and v3 represents the rod loading speed.
[0025] The temperature of the optical fiber light rod refers to the temperature state of the optical fiber during the production process. It is mainly used in the drawing process and heat treatment process. The temperature of the light rod directly affects the drawing quality and performance stability of the optical fiber. Too high or too low temperature will lead to problems such as difficulty in optical fiber drawing, incomplete crystallization, uneven size, etc., which will affect the energy consumption level. It can be obtained by installing a temperature sensor in the optical fiber production equipment to monitor and record the temperature change of the light rod in real time. It can also be obtained by testing the performance of the optical fiber at different temperatures through the method of laboratory testing samples to test the process temperature parameters. The light rod temperature time indicates the length of time that the optical fiber light rod is continuously heated at a certain temperature. The light rod temperature time determines the heating uniformity and crystallization degree of the optical fiber during the heat treatment process. It affects the physical properties and structural characteristics of the product to a certain extent. It is an important parameter for evaluating the effect of the heating process and controlling the heat treatment process. It can be obtained by recording the heating time in real time during the production process or conducting laboratory tests on the heating process. It can also be calculated based on the data of the heating curve and cooling curve to obtain the heating time of the light rod at different temperatures. Rod grinding time refers to the length of time used to polish the surface of the optical fiber during the optical fiber production process. It is an important process step to ensure the smoothness and quality of the optical fiber surface, affecting the smoothness and quality of the optical fiber surface. While ensuring product quality, it will also consume a certain amount of energy and materials. Rod grinding time can be obtained through real-time collection and recording by the equipment monitoring system. Polishing speed is the speed of the machine operation in the polishing process, that is, the moving speed of the optical fiber surface relative to the polishing head during the polishing process. It can be obtained through equipment parameter settings or production operation records. Reasonable control of polishing speed can ensure the smoothness and polishing uniformity of the optical fiber surface. Rod loading speed is the drawing speed of the optical fiber on the drawing machine in the drawing process, that is, the drawing speed of the optical fiber from the blank rod to the terminal product. It can be obtained through equipment parameter settings or production operation records. Reasonable control of rod loading speed can affect the drawing quality and dimensional stability of the optical fiber.
[0026] In step S13, the initial energy consumption per unit time, initial output per unit time, and equipment parameters of each process are obtained.
[0027] In one implementation, the electric meter data of the equipment is obtained; statistics and reading are performed according to the electric meter data of the equipment to obtain the initial energy consumption per unit time; the production data of the production scheduling system is obtained; query processing is performed according to the production data to obtain the working time, the number of production pieces in stable production before the equipment is shut down, the optical fiber output and the initial unit time output; statistical calculation is performed according to the optical fiber output to obtain the time when the equipment enters stable production after starting up and preheating and the stable production time; the number of production pieces in stable production before the equipment is shut down is compared with the optical fiber output to obtain the time when the number of production pieces reaches stability; calculation is performed according to the initial unit time energy consumption and the initial unit time output to obtain the preheating time before the equipment is run; the working time, the preheating time before the equipment is run, the time when the equipment enters stable production after starting up and preheating, the time when the number of production pieces reaches stability and the stable production time are statistically added to obtain the total equipment time; wherein the equipment parameters include: the total equipment time, the working time, the preheating time before the equipment is run, the time when the equipment enters stable production after starting up and preheating, the number of production pieces in stable production before the equipment is shut down, the time when the number of production pieces reaches stability and the stable production time.
[0028] Initial unit time energy consumption refers to the amount of energy consumed by the equipment per unit time. Initial unit time output refers to the number of products produced by the equipment per unit time. The preheating time before the equipment is operated refers to the period of time that the equipment needs to go through before starting to reach a stable working state. The optical fiber production equipment needs to be preheated before starting to ensure the normal operation of the equipment and improve production efficiency, thereby reducing energy consumption. The length of the preheating time will directly affect the arrangement of the production plan and the improvement of production efficiency. By accurately measuring the preheating time, it is possible to avoid unnecessary energy waste caused by the failure of the equipment to start in time. Stable production time refers to the time required for the equipment to reach a stable production state from startup. In the optical fiber production process, the equipment needs a certain amount of time to gradually enter a stable production state to ensure the smooth progress of the production process. The length of the stable production time will directly affect the product quality and production efficiency. The number of production pieces refers to the number of products produced by the equipment in a production cycle. The number of production pieces directly reflects the production efficiency and output level of the equipment. By accurately counting the number of production pieces, the production capacity of the equipment can be evaluated, and then reasonable production plans and scheduling arrangements can be formulated. The number of pieces of stable production before the equipment is shut down refers to the number of products produced in the stable production state before the equipment is about to be shut down. This parameter is used to evaluate the production efficiency and output level of the equipment at the end of the production cycle. By counting and recording this parameter, we can understand the production capacity of the equipment at the end of the production cycle, evaluate the production efficiency, and determine the number of products actually completed in the production cycle. The time for the number of pieces to reach stability refers to the time from the start of the equipment to the final output reaching a relatively stable state during the production process. This time period is the time when the equipment or production line enters the normal production state. In actual production, the number of pieces produced generally goes through a short debugging and adaptation phase after the equipment is started, and gradually increases over time until it reaches a stable level.
[0029] In step S14, the optical fiber process energy consumption and the initial energy consumption per unit time are input into a yield calculation formula for calculation to obtain the optical fiber process yield.
[0030] In one implementation, the optical fiber process yield is calculated as follows: Q1=E / M1 Among them, Q1 represents the optical fiber process output, E represents the initial energy consumption per unit time, and M1 represents the optical fiber process energy consumption.
[0031] Furthermore, the fiber optic rod temperature is calculated by: T1=T+W×t1 Wherein, T1 represents the temperature of the optical fiber light rod, t1 represents the temperature time of the optical fiber light rod, W represents the heating power, and T represents the temperature setting value.
[0032] The fiber optic process output represents the number of optical fibers produced per unit time and is a key indicator for measuring production efficiency. The temperature setting value represents the pre-set target temperature, which is the target temperature that needs to be achieved during the fiber optic manufacturing process. The quality and stability of the optical fiber can be ensured by setting the appropriate temperature value. The heating power represents the power heated per unit time, that is, the heating speed and intensity. This parameter affects the heating speed of the optical fiber light rod, and thus affects the product quality and production efficiency. By reasonably setting the heating power and controlling the heating process, it can ensure that the optical fiber material is in a suitable temperature range. The fiber optic light rod temperature time represents the time that the fiber optic light rod temperature passes, which is the duration of the optical fiber heating process. This parameter affects the final temperature reached by the optical fiber light rod, and also reflects the continuity and stability of the heating process. By controlling the heating time, the uniform heating and stable temperature of the optical fiber light rod can be ensured.
[0033] In step S15, a construction operation is performed according to the equipment parameters and the optical fiber process energy consumption to obtain an energy consumption relationship model.
[0034] In one implementation, the specific type of optical fiber is obtained; a computer performs classification and setting according to the specific type and the equipment parameters to obtain type parameters; a model is constructed according to the type parameters and the optical fiber process energy consumption to obtain an energy consumption relationship model.
[0035] In this step, it is necessary to clearly obtain the specific type of optical fiber being produced. Different types of optical fibers have different production processes, materials and requirements. Therefore, an independent energy consumption relationship model needs to be constructed for each type of optical fiber. By clarifying the type of optical fiber, the energy consumption characteristics of its production process can be analyzed in a targeted manner, thereby saving energy consumption. After obtaining the specific type of optical fiber, it is necessary to use a computer to classify it according to the specific type and equipment parameters. It can be specifically divided into single-mode optical fiber, multi-mode optical fiber and special material optical fiber, etc. Different types of optical fibers are matched and set with corresponding equipment parameters to ensure that the production process data of various optical fibers can be accurately monitored and recorded. Classification settings through computers can improve efficiency and ensure data accuracy and reliability. According to equipment parameters and optical fiber process energy consumption, combined with specific types and classification settings, type parameters can be obtained. These type parameters include key parameters such as production speed, heating temperature, heating time, etc. of different types of optical fibers. The acquisition of type parameters is to fully consider the characteristics and requirements of different types of optical fibers when constructing energy consumption relationship models, so as to more accurately evaluate and control energy consumption. According to the obtained type parameters and optical fiber process energy consumption, a mathematical modeling method is used to build a model based on actual data and parameter calculations, and then an energy consumption relationship model is obtained. This model can help analyze and predict the energy consumption of different types of optical fibers and find methods and strategies for energy saving and consumption reduction.
[0036] In step S16, a construction operation is performed according to the energy consumption relationship model and the optical fiber process output to obtain a standard energy consumption and output relationship model.
[0037] The energy consumption relationship model and the optical fiber process output obtained are used to construct a standard energy consumption-output relationship model using mathematical modeling methods. The relationship between energy consumption and output is quantified and analyzed, including the linear relationship between energy consumption and output in the production process. By establishing a standard energy consumption-output relationship model, the model results are analyzed and evaluated in detail. By comparing actual data with model prediction results, the accuracy and reliability of the standard energy consumption-output relationship model can be verified. At the same time, the standard energy consumption-output relationship model can also be used for sensitivity analysis to explore the impact of different parameter changes on energy consumption and output.
[0038] In step S17, calculation is performed according to the standard energy consumption-output relationship model to obtain the equipment start-stop time series.
[0039] In one implementation, the operating status of the equipment is obtained; a judgment is made based on the operating status of the equipment to obtain an automatic start-stop status and a non-automatic start-stop status; when the operating status of the equipment is the automatic start-stop status, the current energy consumption and the current output of the current time period are counted, and the current energy consumption and the current output are input into a standard energy consumption-output relationship model for calculation to obtain a model energy consumption, and a time series is formulated based on the model energy consumption to obtain an equipment start-stop time series; when the operating status of the equipment is the non-automatic start-stop status, the working status of the equipment is monitored to obtain a working status and a stopped working status, and when the equipment is monitored to be in the stopped working status for two consecutive times and the interval length is not the system preset downtime, the equipment is automatically shut down.
[0040] In one implementation, when the energy consumption of the model reaches a preset threshold, the device automatically shuts down for a preset time and then automatically restarts; wherein the preset threshold and preset time are data pre-stored in the system and automatically set by a computer.
[0041] Through sensors or monitoring systems, the equipment is monitored in real time to obtain the equipment's operating status, including whether the equipment is in operation, stopped, or automatic start-stop status. Based on the acquired equipment operating status data, the system will determine whether the equipment is currently in automatic start-stop status or non-automatic start-stop status. The automatic start-stop status means that the equipment can adjust the start and stop autonomously according to production needs, while the non-automatic start-stop status requires computer forced intervention to control the start and stop of the equipment. When the equipment is in the automatic start-stop state, the system will count the current energy consumption and current output in the current time period, and input them into the standard energy consumption and output relationship model for calculation to obtain the model energy consumption. According to the results of the model energy consumption, when the model energy consumption reaches the preset threshold, the system will automatically shut down the equipment and automatically start up after the preset time. The system will formulate the start-stop time sequence of the equipment to achieve the best energy utilization and output efficiency. For example, when the unit time capacity Q is 1 (capacity of 500,000 cores per hour), the unit time energy consumption E is 50Mw, and the equipment operating parameters (C, D, Y, z, J) are D=1h, J=1h, Y=500,000 cores, Z=10min, according to the energy-saving operation model of the production equipment, the equipment operating parameters corresponding to the unit time energy consumption E in the relationship model are equal to or higher than C. 1.5h, then the output equipment will automatically shut down for 2 minutes and then automatically start up. When the equipment is in a non-automatic start-stop state, the system will continuously monitor the working status of the equipment, including the working state and the stopped working state. When the equipment is detected to be in a stopped working state for two consecutive times and the interval time is not the preset downtime of the system, the system will trigger the automatic shutdown procedure of the equipment to avoid energy waste and increase the service life of the equipment. When the equipment is in working state, if the preheating time + the time for the equipment to enter stable production after starting preheating is greater than the number of pieces produced in stable production before the equipment is shut down - the time when the number of pieces reaches stability, it means that if the equipment is started at this time, the output that can be completed within the time of the number of pieces produced in stable production before the equipment is shut down - the number of pieces reaches stability will not increase after the preheating time before the equipment is run + the time for the equipment to enter stable production after starting preheating, then the output device will automatically shut down.
[0042] In step S18, an optimal energy-saving control strategy is determined according to the equipment start-stop time sequence and input into a controller to control the start-stop of the equipment.
[0043] The equipment start-stop time series obtained in step S17 is used as basic data. These data include information such as the start-stop time point, duration and frequency of the equipment. The system will analyze these data to understand the operating characteristics and energy consumption of the equipment in different time periods, so as to formulate the optimal energy-saving control strategy. According to the equipment start-stop time series and its analysis results, the system will determine the optimal energy-saving control strategy. This strategy includes reasonably arranging the start-stop time of the equipment, adjusting the operation mode of the equipment or cooperating with the operation of other equipment to achieve energy-saving effects, for example, appropriately reducing the equipment operation time during low-load periods, or taking energy-saving measures during peak hours. After determining the optimal energy-saving control strategy, the system will input these data into the controller. The controller is an automated system that can control the start-stop of the equipment according to the preset control strategy. Through the controller, the system can achieve precise control of the equipment to ensure that the equipment operates according to the best energy-saving solution. The optimal energy-saving control strategy is input into the controller, and the controller will start to execute these strategies, that is, control the operation of the equipment according to the preset start-stop time series. At the same time, the system also needs to monitor the execution of the controller to ensure that the operation of the equipment meets the expected energy-saving effect, and adjust the strategy in time to adapt to the actual production situation.
