The terms used herein are only for the purpose of describing the embodiments of the present application.

[0021] An embodiment of the present application provides a high-efficiency energy-saving control method based on a dyeing machine, as Figure 1 shown, the method includes:

[0022] Step S100, import dyeing formula and work order information, perform overall analysis of work orders based on the ERP module, and determine dyeing material preparation information, where the dyeing material preparation information includes material preparation requirements, liquor ratio requirements, and temperature control requirements.

[0023] Preferably, the dyeing formula refers to the specific formula information determined for the dyeing process, including the types, quantities, and mixing ratios of the required dyes and auxiliaries. It is usually designed according to different dye types, fabric materials, and color requirements. The work order information refers to the dyeing tasks for each batch in the production process, including production batches, production dates, dyeing requirements, order quantities, customer demands, etc., which are used to guide material preparation, process parameters, time arrangements, etc. during the dyeing process; the ERP module, i.e., the enterprise resource planning module, is used to integrate various resources, conduct production scheduling and management. Specifically, the ERP module conducts overall analysis of the work order for the dyeing formula and work order information, that is, comprehensively analyzes the production plan, material requirements, inventory status, equipment conditions, etc. of the dyeing work order to effectively allocate resources and optimize the production process, including making global planning and optimization based on the existing work order information and production arrangements to ensure that all resources (such as dyes, auxiliaries, machinery and equipment, personnel, etc.) can be reasonably arranged, avoiding resource conflicts or waste, and then determining the dyeing material preparation information, that is, all preparatory work related to the dyeing process, including material preparation requirements, liquor ratio requirements, and temperature control requirements. Among them, the material preparation requirements refer to the types and quantities of all materials (such as dyes, auxiliaries, auxiliary materials, etc.) prepared in advance according to the dyeing formula and work order requirements; the liquor ratio refers to the ratio of water, dyes, and auxiliaries in the dyeing solution (i.e., the dye solution), and the liquor ratio requirement is to calculate and determine the required ratio of water and dyes (auxiliaries) according to the requirements of the dyeing process. An appropriate liquor ratio is the key to ensuring dyeing quality, which can not only ensure the dyeing effect but also save dyes and water resources to the greatest extent; the temperature control requirement refers to the precise temperature control requirement during the dyeing process. In different dyeing processes, the temperature of the dyeing solution needs to be controlled within a certain range to ensure the dissolution, fixation of the dyes, and the stability of the dyeing quality. The temperature control requirement determines the specific values and change ranges of temperature control according to the requirements of the dyeing formula and the requirements for dyeing quality in the work order, providing accurate material and process parameters to ensure that the dyeing process can be carried out on the basis of energy conservation and high efficiency while ensuring dyeing quality.

[0024] Step S200, based on the dyeing material preparation information, perform automated feeding control and temperature control management of the dyeing machine.

[0025] Preferably, convert the specific material information required during the dyeing process (such as dyes, auxiliaries, water, and temperature requirements) into automated control operations to optimize the efficiency and energy-saving effect of the dyeing process. Specifically, the automated feeding control of the dyeing machine refers to automatically controlling the conveying process of various materials in the dyeing machine (such as dyes, auxiliaries, water, etc.) based on the dyeing preparation information. Depending on the preset process requirements and preparation information, it automatically adjusts the input amounts of different materials to ensure the precise ratio of dyes, auxiliaries, and water during the dyeing process, avoiding human operation errors or material waste. In actual operation, the automated feeding control is usually achieved by proportional valves (for regulating flow rates), sensors (for monitoring material flow rates and liquid levels), and control systems (automatically adjusting the flow rate through feedback control). For example, water valves, auxiliary valves, and dye valves are adjusted by proportional valves to precisely control the flow rates of water, auxiliaries, and dyes according to the ratio required by the bath ratio, thus achieving the effect of precise formulation. The role of automated feeding control is to improve production efficiency, ensure that various materials are automatically added in the optimal ratio, avoid errors and waste caused by manual operations, and at the same time improve the stability of the dyeing quality.

[0026] Preferably, the temperature control management of the dyeing machine refers to, according to the temperature control requirements in the dyeing formula, through temperature sensors and frequency converters, real-time monitoring of the temperature of the dyeing solution and automatically adjusting the heating or cooling system of the dyeing machine to ensure that the temperature of the dyeing solution is within a predetermined range. Specifically, the temperature control management performs automatic feedback control through a temperature frequency converter and a temperature sensor. The temperature frequency converter can, based on the real-time monitored temperature of the dyeing solution, precisely control the temperature of the dyeing solution by adjusting the heating or cooling power, ensuring that the dyeing process is always under the best temperature conditions, thereby improving the solubility of the dye and the dyeing effect. Temperature control is an important part of the dyeing process. Too high or too low temperature will affect the solubility of the dye and the uniformity of dyeing. The automated management of temperature control can improve the stability of the dyeing process, ensure the dyeing quality of the product, and at the same time avoid energy waste caused by overheating. Through an integrated automated management method (precisely adjusting material conveying and temperature control parameters), the efficiency, energy-saving performance, and product quality stability of the dyeing process are significantly improved.

[0027] Among them, the control methods include:

[0028] Step A, assemble a differential pressure transmitter and a temperature frequency converter on the dyeing machine. Among them, the differential pressure transmitter has a first feedback rule built-in, and the temperature frequency converter has a second feedback rule built-in. The feedback rule includes an original rule - knowledge association function - correction rule.

[0029] Preferably, a differential pressure transmitter and a temperature frequency modulator are assembled on the dyeing machine. Through precise sensors (differential pressure transmitter and temperature frequency modulator), real-time control of materials and temperature during the dyeing process is achieved, and automatic correction is carried out in combination with feedback control rules to optimize the dyeing effect and energy-saving effect. Among them, the differential pressure transmitter is a sensor used to measure the pressure difference between two points, mainly applied in the process of liquid or gas flow. Especially in the dyeing process, it can be used to monitor the flow, liquid level or pressure difference of the dyeing liquid. Specifically, by measuring the flow state of the dyeing liquid in the dyeing machine, it helps to precisely control the supply of the dyeing liquid, especially to control the flow of the liquid in each part of the dyeing machine to ensure that the liquid is evenly distributed at the optimal bath ratio; the temperature frequency modulator is a device used to adjust and control the temperature of the dyeing liquid in the dyeing machine. It is usually equipped with a temperature sensor to monitor the temperature of the dyeing liquid in real time and adjust the heating or cooling equipment through feedback control to ensure that the dyeing liquid remains within a preset ideal temperature range. The temperature control system can effectively prevent the temperature from being too high or too low to ensure the best solubility of the dye and the dyeing effect.

[0030] Preferably, the differential pressure transmitter is built-in with a first feedback rule, which refers to formulating a feedback control mechanism to adjust the liquid flow rate or ratio in the dyeing machine based on the pressure difference data measured by the differential pressure transmitter and in combination with the change of the flow state of the dyeing liquid. The core is the nested structure of the original rule - knowledge association function - correction rule. Through these rules, precise control of the liquid flow rate in the dyeing machine is achieved. Specifically, the original rule refers to the standard of the basic flow rate, liquid level or pressure difference set according to the theoretical calculation in the initial stage of the dyeing machine design. The knowledge association function refers to combining the characteristics of the dyeing liquid, the actual situation of the equipment and historical data, and through the knowledge association function, different parameters (such as dye type, fabric characteristics, liquid flow rate, etc.) are associated to form a dynamic control method suitable for the current dyeing process. The correction rule refers to correcting and optimizing the original rule through real-time feedback information to eliminate the influence of equipment deviation or external interference and ensure that the liquid flow rate in actual operation can accurately match the set target.

[0031] Preferably, the temperature frequency regulator is built with the second feedback rule, which refers to the temperature control management for dyeing solution, that is, the temperature frequency regulator is based on the deviation of the dyeing solution temperature and the target temperature actually monitored, and the working power of the heating or cooling system is adjusted in real time to maintain a stable temperature condition. The second feedback rule also includes the original rule-knowledge association function-correction rule, and the original rule is to set the target dyeing temperature range and the preliminary strategy of temperature regulation (for example, the amplitude of the temperature change per hour or the allowed fluctuation range), the knowledge association function is to combine the factors such as the type of dye, ambient temperature, and the thermal conductivity characteristics inside the dyeing machine, and the knowledge association function is used to adjust the temperature control strategy to ensure the optimal temperature condition. The correction rule is to adjust the control rule according to the actual temperature data fed back by the sensor, and correct possible deviations, such as the temperature fluctuations caused by the external environment changes, or the heat transfer efficiency changes of the equipment itself. The combination of two feedback rules enables the dyeing machine to automatically adjust the flow rate (feedback by the differential pressure transmitter) and the temperature (feedback by the temperature frequency regulator) of the dyeing solution according to real-time data, ensuring the precise control of the dyeing process. The feedback rules will adjust operations according to real-time deviations to achieve automatic correction. Even if there are fluctuations in liquid flow or temperature during the dyeing process, they can be automatically adjusted according to the feedback data to avoid color difference problems caused by uneven dye dissolution or unstable dyeing liquid temperature, ensuring the consistent dyeing quality of each batch of dyed products and ensuring dyeing quality and energy-saving effects.

[0032] Furthermore, step A also includes step A10, setting a first original rule according to the bath ratio requirement and the dyeing machine characteristics, wherein the first original rule is a fuzzy feedback rule for pressure difference transmission regulation; step A20, based on multiple control scenarios, taking the first original rule as a benchmark, performing correlation mining between correction rules and original rules, and constructing a first knowledge association function, wherein the first knowledge association function is used to correct the first original rule; step A30, combining the first original rule-first knowledge association function-first correction rule to determine the first feedback rule, wherein the first correction rule is initially empty.

[0033] Preferably, a fuzzy feedback control system is used to accurately adjust the liquid flow in the dyeing machine to ensure that various parameters in the dyeing process (such as the proportion of liquids) meet the predetermined requirements. Specifically, based on the bath ratio requirements and the characteristics of the dyeing machine, a first original rule is set, that is, a fuzzy feedback rule for pressure differential transmitter regulation. For example, when there is fine-tuning of the cloth material, requirements, etc., the initial rule may not be suitable, but different requirements are configured with rules. The differential pressure transmitter measures the pressure difference between the upper and lower water levels during the flow of the dyeing liquid, which is used as a feedback signal to control the flow of the liquid. The fuzzy feedback rule adjusts the liquid flow according to the feedback signal of the pressure difference to ensure that the proportion of the dyeing liquid (bath ratio) meets the requirements. For example, if the pressure difference is too large, the system will infer that the liquid flow rate is too fast or too slow, and make corresponding adjustments.

[0034] Preferably, according to the multi-control scenarios of the dyeing machine (such as temperature control, liquid flow control, ratio regulation of dyes and auxiliaries, etc.), based on the first original rule, the correlation between the correction rule and the original rule is mined, that is, data analysis is carried out through the relationships between multiple control factors to find out which factors affect the effectiveness of the original rule, and optimize and adjust accordingly. A first knowledge association function is constructed, which is a mathematical function that combines the original rule and the correction rule and is used for knowledge association and extraction. By analyzing the feedback data (such as pressure difference, flow rate, temperature, etc.) under different control scenarios and the output of the original rule, a knowledge association function is constructed. This function can correct the original rule in real time to cope with various changes that may occur during the production process, and can automatically adjust the original control rule according to the actual working condition feedback information, thereby improving the adaptability and accuracy of the system. Based on the combination of the original rule, the knowledge association function and the correction rule, the first feedback rule is determined, that is, according to the information such as the liquid flow rate and pressure difference measured in real time, the operating parameters of the dyeing machine are adjusted through feedback to ensure that the liquid flow rate (bath ratio) meets the requirements. Among them, the correction rule is initially empty, indicating that the correction rule is initially an empty template and will be gradually filled and optimized according to the continuously collected data and feedback information.

[0035] Further, step A further includes step A40 of setting a second original rule according to the temperature control requirement and the characteristics of the dyeing machine, where the second original rule is a fuzzy feedback rule for dyeing temperature regulation; step A50 of mining the correlation between the correction rule and the original rule based on the change of the dyeing characteristics with the second original rule as the benchmark, and constructing a second knowledge association function; step A60 of determining the second feedback rule by combining the second original rule - the second knowledge association function - the second correction rule.

[0036] Preferably, based on the preliminary control rule set according to the temperature control requirement during the dyeing process (the specific requirement for the temperature of the dyeing solution during the dyeing process) and the characteristics of the dyeing machine (the specific heating and cooling capabilities, heat transfer efficiency, etc. of the dyeing machine), that is, the second original rule, the second original rule is a fuzzy feedback rule for dyeing temperature regulation. The fuzzy feedback rule is based on the temperature data measured in real time (such as the temperature of the dyeing solution), and decides whether to adjust the power of the heater or start the cooling system through fuzzy inference. For example, if the temperature is too low, the heating power is increased; if the temperature is too high, the cooling system is started. According to different input temperature errors (such as the degree of temperature deviation from the set value), the working states of the heating and cooling systems are automatically adjusted through fuzzy inference to keep the temperature of the dyeing solution within the optimal range.

[0037] Preferably, for changes in dyeing characteristics (including types of dyes, types of fabrics, properties of dyeing solutions, etc.), for example, the temperature requirements for different dyeing stages, dyeing characteristics for different targets, etc. may vary. The original temperature control rule (the second original rule) may not be able to fully handle all changes. For example, certain dyes may require different temperature ranges to achieve the best results, or the dyeing temperature requirements for different fabrics are different. It is necessary to correct and optimize the original rule through a correction rule to handle these changes. Correlation mining refers to analyzing the temperature control feedback data under different dyeing process conditions to find the key factors affecting the temperature control effect (such as types of dyes, fabric materials, dyeing environment temperature, etc.) and determining the correlation between these factors and the original control rule. That is, through data mining of the continuously changing control scenarios during the dyeing process, a second knowledge association function is constructed to connect various dyeing characteristics (such as dyes, fabrics, temperature change rate, etc.) with the adjustment methods of the temperature control system (such as adjustment of heating power and cooling power). Furthermore, according to the actual situation of the current dyeing process, the control strategy is automatically adjusted to meet the requirements of different dyeing characteristics. Based on the combination of the second original rule, the second knowledge association function, and the second correction rule, a second feedback rule is determined, which can automatically adjust the power output of the heating or cooling system according to the temperature deviation of the dyeing solution to ensure that the temperature always remains within the ideal range.

[0038] Step B, measure the water level through the pressure difference, and combine with the differential pressure transmitter to perform proportional valve control based on the liquor ratio requirement, where the proportional valve includes a water valve, an auxiliary agent valve, and a dye valve.

[0039] Preferably, a differential pressure transmitter and a proportional valve are used to achieve precise control of materials (such as water, auxiliary agents, dyes) to ensure that the dyeing process meets the preset liquor ratio requirement. Specifically, the differential pressure transmitter calculates the liquid level height of the dyeing solution by measuring the pressure difference inside the dyeing machine (i.e., the pressure difference between the upper and lower water levels), that is, the differential pressure transmitter can calculate the water level in the dyeing machine by monitoring the pressure difference at different positions, and the change in the liquid level in the dyeing machine can be reflected by the change in the pressure difference. In the dyeing process, the liquor ratio refers to the ratio of the dyeing solution (such as water, dyes, auxiliary agents), usually expressed as the ratio of the volume of the liquid to the weight or length of the fabric. Based on the liquor ratio requirement, it is necessary to ensure that the water level of the liquid is within a suitable range to accurately prepare the composition of the dyeing solution. The differential pressure transmitter can provide accurate liquid level information to automatically adjust the addition amount of the liquid according to the liquor ratio requirement.

[0040] Preferably, a differential pressure transmitter is combined for proportional valve control. Among them, the proportional valve is a valve that can adjust the output flow according to the change of the input signal. Through electrical or pneumatic control, it adjusts the flow and pressure of the fluid. In the dyeing machine, the proportional valve is used to control the flow of water, additives, and dyes to ensure that they are accurately added to the dyeing solution according to a predetermined ratio. Specifically, the water valve controls the amount of water added to the dyeing machine to ensure that the liquid level of the dyeing solution and the bath ratio requirements are met. If the differential pressure transmitter detects that the water level is too low or too high, the water valve will adjust the water flow to maintain an appropriate water level; the additive valve controls the flow of dyeing additives (such as surfactants, dye assistants, etc.). Additives play a role in improving the dyeing effect and increasing the dye adsorption efficiency during the dyeing process. By controlling the flow of additives through the proportional valve, it is ensured that its proportion in the dyeing solution meets the bath ratio requirements; the dye valve is used to control the amount of dye added. The amount of dye added directly affects the dyeing effect and the color fastness of the product. The proportional valve adjusts the opening degree of the dye valve to accurately control the inflow of dye to ensure that the concentration of the dyeing solution meets the predetermined process requirements.

[0041] Preferably, during the dyeing process, based on the water level data measured by the differential pressure transmitter and combined with the bath ratio requirements, the proportional valve will automatically adjust the opening degree or flow rate of the water valve, additive valve, and dye valve according to the liquid level height of the dyeing solution. Specifically, if the liquid level of the dyeing solution is too high, the differential pressure transmitter will feedback a signal to reduce the flow rate of the water valve, that is, reduce the input of water. If the liquid level of the dyeing solution is too low, increase the flow rate of the water valve to supplement water to maintain the bath ratio; similarly, the additive valve and the dye valve will accurately adjust their respective flow rates according to the requirements of the dyeing solution to ensure that the proportions of additives and dyes during the dyeing process are appropriate, thus ensuring the consistency of the dyeing quality. The automatic control of the whole process ensures the accurate adjustment of water, additives, and dyes during the production process, avoiding the errors and instabilities that may be brought by manual control, thereby improving the repeatability, stability, and energy efficiency of the dyeing process, while reducing energy waste and material waste.

[0042] Furthermore, step B further includes step B10, using an auxiliary pressure sensor to measure the water level of the dyeing solution by differential pressure to determine the water level in the machine cylinder, where the differential pressure is the difference between the standard pressure based on the bath ratio requirements and the measured pressure; step B20, transmitting the water level in the machine cylinder to the differential pressure transmitter, determining the bath ratio characteristics and performing a differential limit determination to generate a bath ratio control instruction, where the limit determination is performed with a preset bath ratio tolerance; step B30, performing proportional valve control based on the bath ratio control instruction.

[0043] Preferably, an auxiliary pressure sensor and a differential pressure transmitter are used to precisely control the water level of the dyeing solution, so as to ensure that the bath ratio requirement in the dyeing process is met, and the liquid flow rate is optimized through the regulation of a proportional valve. Specifically, the auxiliary pressure sensor is used to measure the pressure of the liquid in the dyeing machine, usually installed at different positions of the dyeing machine to monitor the pressure difference of the dyeing solution, so as to calculate the water level of the dyeing solution. By accurately measuring the water level, it can be ensured that the water level of the dyeing solution always meets the bath ratio requirement, that is, by setting the standard pressure (for example, the pressure of the dyeing solution based on a predetermined bath ratio) and the measured pressure (the actually measured pressure of the dyeing solution), the pressure difference can be calculated, which directly affects the liquid flow rate and liquid level, and thus affects the bath ratio control.

[0044] Preferably, the water level of the dyeing solution measured by the auxiliary pressure sensor is transmitted to the differential pressure transmitter. The differential pressure transmitter calculates the bath ratio characteristic in the current dyeing machine based on the received water level information, which reflects whether the ratio between the current liquid and the fabric meets the expectation. If the amount of the dyeing solution is too much or too little, the liquid flow rate is adjusted according to the feedback information of the differential pressure transmitter to ensure that the bath ratio meets the requirement; a permitted bath ratio tolerance (i.e., the error range of the liquid ratio) is set. If the measured liquid level deviates from the standard value by more than the preset tolerance range, an over-limit determination will be triggered, that is, an abnormality in the liquid flow rate or water level is detected, and a corresponding regulation instruction is generated. Here, the tolerance represents the permitted error range. For example, if the standard value of the bath ratio is 1:10 and the actual water level deviation exceeds the set tolerance range (such as a 1% deviation), the over-limit determination is triggered, indicating that the current liquid level does not meet the set bath ratio requirement; finally, according to the bath ratio regulation instruction, the proportional valve precisely controls the flow rate of each liquid (such as water, additives, dyes) to ensure that their ratio to the fabric meets the preset bath ratio, ensuring the correct ratio of the dyeing solution and guaranteeing the stability and consistency of the dyeing quality.

[0045] Further, step B30 further includes step B31, for the bath ratio characteristic, execute an adjustment decision based on the target feedback rule to determine the dye solution adjustment amount, where the target feedback rule is the first original rule or the first correction rule; step B32, with the dye solution adjustment amount as the target, determine the bath ratio regulation strategy, where the bath ratio regulation strategy includes the regulation amount and the delivery rate, the regulation amount includes the water intake, the additive amount and the dye amount, and the dye has a pre-dissolution treatment; step B33, based on the bath ratio regulation strategy, perform opening and closing control on the proportional valve.

[0046] Preferably, according to the bath ratio characteristic, the adjustment decision based on the target feedback rule (the first original rule or the first correction rule) is executed to determine the amount of dye solution to be adjusted and the adjustment direction (such as increasing or decreasing the flow rate of dye, auxiliary agent or water), and the ratio of the dyeing solution will be adjusted according to the feedback rule to ensure that it meets the target bath ratio. Here, the amount of dye solution adjustment refers to the volume or flow rate of the dyeing solution to be adjusted. For example, by measuring the liquid level of the dye solution in the dyeing machine and the target bath ratio, it is found that the liquid level is lower than the expected target value, and it is decided to increase the amount of water, auxiliary agent or dye to adjust the bath ratio until the set target is reached; then, based on the amount of dye solution adjustment, the bath ratio control strategy is determined, specifically including the amount of substances to be adjusted, such as the amount of water inlet, auxiliary agent and dye, and the conveying rate (the dye needs to be pre-dissolved before being added to the dyeing machine to ensure that it can be completely dissolved in the dyeing solution and improve the dyeing effect), to ensure the solubility and uniformity of the dye, so that there will be no dye particle precipitation or non-uniformity during the dyeing process; finally, the opening and closing of the proportional valve is controlled according to the bath ratio control strategy, that is, according to the demand of the bath ratio control strategy inside the dyeing machine, the opening of the valve is automatically adjusted to accurately control the liquid flow rate. If the amount of dyeing solution is insufficient, the proportional valve will increase the flow rate of water, dye or auxiliary agent; if the liquid amount is too much, the proportional valve will reduce the flow rate; thus ensuring that the flow rate, liquid level and bath ratio of the dyeing solution always meet the expectations, thereby guaranteeing the stability and consistency of the dyeing quality.

[0047] Step C, through dye solution temperature measurement, combined with the temperature frequency modulation device, perform power control based on the temperature control requirement.

[0048] Preferably, by precisely measuring the temperature of the dye liquor and automatically adjusting the heating or cooling power according to the temperature control requirements, the precise control of the temperature during the dyeing process is ensured, thereby achieving an efficient and stable dyeing effect. Specifically, during the dyeing process, the temperature of the dye liquor is a key factor affecting the dyeing quality. Too high or too low temperature will have a negative impact on the solubility of the dye, the dyeing uniformity of the fabric, and the time efficiency of dyeing. The measurement of the dye liquor temperature usually relies on a temperature sensor, which can monitor the temperature of the dye liquor in real time. That is, by installing a temperature sensor in the dyeing machine, the temperature data of the dye liquor can be obtained in real time, enabling the dyeing machine to make corresponding adjustments according to the deviation between the actual dye liquor temperature and the target temperature. Then, in combination with a temperature frequency converter for power regulation. Among them, the temperature frequency converter is an automatic control device for controlling the temperature of the dyeing solution, which can precisely adjust the temperature of the dye liquor inside the dyeing machine by adjusting the power of the heater or the operating state of the cooling device according to the feedback information of the temperature sensor. For example, if the temperature of the dyeing solution feedback by the temperature sensor is lower than the set value, the temperature frequency converter will increase the heating power to gradually raise the temperature of the dyeing solution until the preset temperature control requirements are reached. If the temperature of the dyeing solution exceeds the set upper limit, the temperature frequency converter will reduce the heating power or start the cooling system to quickly reduce the temperature to an appropriate range. The temperature frequency converter generally uses a feedback control mechanism (such as PID control), which can adjust the power output of heating or cooling according to the difference (temperature error) between the dye liquor temperature and the target temperature to ensure that the temperature change rate is stable and meets the process requirements.

[0049] Preferably, during the dyeing process, different dyes and fabrics need to be in a specific temperature range to obtain the best dyeing effect. The temperature control requirement refers to the precise setting of the temperature of the dyeing solution according to the dyeing formula and process requirements, usually including two aspects: the temperature range (setting the upper and lower limits of the dye liquor temperature. For example, some dyes need to be dyed between 80°C and 90°C) and temperature stability (avoiding excessive temperature fluctuations to ensure a uniform dyeing effect and no color difference). By combining the real-time data measured by the temperature sensor, the temperature frequency converter will automatically adjust the power of the heater or cooling device according to the set temperature control requirements to ensure that the temperature of the dye liquor always remains within an accurate range. By precisely controlling the temperature of the dye liquor, the solubility of the dye can be optimized, ensuring the uniform distribution of the dye on the fabric, thereby improving the dyeing quality. Excessive heating power not only wastes energy but may also cause excessive temperature fluctuations, affecting the dyeing effect. By automatically adjusting the power, a stable dyeing temperature can be maintained, thereby improving the dyeing efficiency and reducing energy consumption.

[0050] Step S200 further includes step S210 of dividing the fabric dyeing stage and determining key cycle nodes based on the fabric dyeing cycle; step S220 of traversing the key cycle nodes, determining the fabric dyeing state, and determining the fabric state chain, where the fabric state chain is constructed based on the fabric dyeing states of each key cycle node in chronological order; step S230 of performing dyeing control management on the fabric dyeing quality according to the fabric state chain.

[0051] Preferably, fabric dyeing can generally be divided into several different stages, each stage having different dyeing characteristics and operation requirements, which may include pretreatment, dye dissolution, dyeing, shaping, cooling, etc. By dividing the dyeing process into stages, the time nodes and operation conditions of each stage can be clearly identified, so as to better control and manage. Determine the key cycle nodes based on the fabric dyeing cycle according to the key cycle nodes. Among them, the key cycle nodes refer to the crucial moments during the dyeing process. For example, the moment when dyeing starts, the moment when the temperature reaches the preset value, the moment when the dye is added, the moment when dyeing is completed, etc., which may affect the contact time between the dyeing solution and the fabric, the dissolution and fixation of the dye, and are directly related to the dyeing quality and efficiency; during the dyeing process, the state of the fabric (dyeing degree, dye adsorption situation, temperature, etc.) will change with the change of each key cycle node. By traversing each key cycle node, record and analyze the dyeing state of the fabric at each node in turn. For example, the dyeing uniformity of the fabric, the penetration depth of the dye, the temperature of the dyeing solution, the solubility of the dye, etc. can all constitute the dyeing state. By monitoring and recording these states, the progress of the fabric during the entire dyeing process can be understood; then, the dyeing states of each key cycle node are connected in series according to the time sequence to form a fabric state chain, which describes the change process of the fabric dyeing state from start to finish during the entire dyeing cycle.

[0052] Preferably, perform dyeing control management on the fabric dyeing quality according to the fabric state chain. Specifically, by analyzing the fabric state chain, identify possible problems in the dyeing process. For example, the dyeing state of a certain key node may show that the dye dissolution is insufficient, or the temperature of the dyeing solution is too high, resulting in uneven dyeing. Perform immediate regulation on the dyeing process according to the current dyeing state, including adjusting multiple factors such as the temperature of the dyeing solution, the dye concentration, the amount of auxiliary agents used, and the dyeing time, such as adjusting the temperature, extending the dyeing time, increasing the amount of dye or auxiliary agent. Through refined dyeing control management, the stability of the dyeing effect can be improved, resource waste can be reduced, and high-quality output of the final product can be ensured.

[0053] Further, step S200 further includes step S240 of setting a preset response time zone, and based on the preset response time zone, performing regulation response tracking on the dyeing machine and monitoring regulation response data; step S250 of performing an expected evaluation on the regulation response data, and performing regulation deviation correction management based on response vector deviation and response bias.

[0054] Preferably, in the dyeing machine control system, a preset response time zone is set for each operation, which is used to monitor the response behavior of the dyeing machine under specific operations, mainly for capturing the reactions generated by the dyeing machine during the operation process, ensuring the stability of the regulation process. If the reaction of the dyeing machine does not proceed as expected within the set response time zone (for example, the temperature does not reach the target value within the predetermined time), it will trigger regulation adjustment or an alarm; continuously monitor the regulation behavior and data response of the dyeing machine within the preset time zone, and automatically collect all key regulation data, including but not limited to temperature, dye concentration, flow rate, pressure, etc., to ensure that these data can reflect the regulation response of the dyeing machine in real time; during the regulation response tracking process, compare the real-time collected regulation response data with the expected target, where the expected target is usually the ideal parameters set at the initial stage of the dyeing process (for example, the target temperature, dye concentration, etc. of the dyeing solution), to determine whether the dyeing machine completes the operation as per the predetermined target within the response time zone, identify the deviation, and make timely adjustments. Specifically, the response vector deviation refers to the difference between the actual response of the dyeing machine (such as temperature change, dye concentration, etc.) and the expected target, and the response bias refers to whether there is a systematic error or trend in the regulation process of the dyeing machine; finally, perform regulation deviation correction management based on the vector deviation and bias in the regulation response data, that is, adjust or correct the control of the dyeing machine, including automatically adjusting parameters such as heating power, dye delivery volume, liquid flow rate, etc., to eliminate errors and make the dyeing process return to the ideal state, thereby ensuring that the operation of the dyeing machine can achieve the predetermined target, ensuring the precise regulation of the dyeing machine in the process, and optimizing the production efficiency and product quality.
