DETAILED DESCRIPTION

[0017] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant application, rather than to limit the application. It is also necessary to explain that, for ease of description, only the parts related to the application are shown in the accompanying drawings.

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] The following is combined with Figure 1 Describe the low-cost and low-carbon emission dyeing vat process intelligent control method, system, equipment and medium according to the embodiments of the present application.

[0020] The dye vat is heated by a burner, which may be a dye vat used in a printing and dyeing factory to dye cloth, etc. The burner uses natural gas as fuel, for example, and controls the firepower by the opening, thereby achieving temperature control of the dye vat.

[0021] Figure 1 1 is a flow chart of a low-cost, low-carbon dyeing vat process intelligent control method according to an embodiment of the present application. Figure 1 As shown, according to an embodiment of the present application, a low-cost and low-carbon intelligent control method for dyeing vat process includes the following steps: S101: Obtaining process data of dyeing a dye target in a dye vat, wherein the process data at least includes the process required temperature, heating / cooling rate and process duration.

[0022] Among them, the process data for dyeing the dyeing target means that the dyeing vat needs multiple temperature changes to dye the dyeing target such as cloth, which generally includes key parameters such as process target temperature, i.e. process required temperature, heating / cooling rate, and insulation time, i.e. process duration. Generally speaking, these parameters will vary depending on the type of cloth being dyed.

[0023] Specifically, if Figure 2As shown, the intelligent control gateway can be connected to the dye vat centralized control system. The dye vat centralized control system can collect process data of dyeing the dyeing target by the dye vat through a bus such as a 485 communication bus, and then send the collected process data of the dye vat to the intelligent control gateway through link 1. The intelligent control gateway then sends the process data to the corresponding processing platform.

[0024] It should be noted that the process data may include some other process parameters in addition to the required process temperature, heating / cooling rate and process duration, for example, the operating status of the dye vat, the water temperature in the vat (i.e. the current temperature of the dye vat), the number of dyeing times, the current process being executed, the start time of the current process, the current process sequence number, the total process sequence number and the type of process steps, etc.

[0025] In a specific example, a data model of process data may be established in advance, so that the process data is sent to the processing platform in the form of a data model, as shown in Table 1, which shows a data model.

[0026] Table 1

[0027] S102: Obtain a temperature target curve according to process data.

[0028] In one embodiment of the present application, a temperature target curve is obtained based on process data, including: establishing a two-dimensional coordinate system with time and temperature as the coordinate axes of the two-dimensional coordinate system; and interpolating the temperature target curve in the two-dimensional coordinate system according to the process required temperature, heating / cooling rate and process duration.

[0029] Specifically, according to the process required temperature and its corresponding process duration, a temperature curve corresponding to the process required temperature can be drawn in a two-dimensional coordinate system with time as the horizontal axis and temperature as the vertical axis, and, according to the heating / cooling rate, a rise / fall curve between different process required temperatures can be drawn, thus forming the entire temperature target curve.

[0030] S103: Obtaining a target opening of the burner according to the current temperature of the dye vat and the temperature target curve.

[0031] In one embodiment of the present application, the target opening of the burner is obtained according to the current temperature of the dye vat and the temperature target curve, including: obtaining the current temperature of the dye vat at a first moment; obtaining the process requirement temperature at the first moment from the temperature target curve; obtaining the target opening of the burner according to the current temperature of the dye vat at the first moment and the process requirement temperature at the first moment.

[0032] In this example, the target opening of the burner is obtained according to the current temperature of the dye vat at the first moment and the process required temperature at the first moment, including: obtaining the temperature difference between the current temperature of the dye vat at the first moment and the process required temperature at the first moment; obtaining the opening adjustment amount according to the temperature difference; obtaining the target opening of the burner according to the opening adjustment amount and the current opening of the burner.

[0033] The first moment may be any moment in the process, for example, at a certain moment, such as Figure 3 As shown, the current temperature of the dye vat (i.e., the actual temperature of the main vat) is 120°C. At this time, by querying the temperature target curve, it can be known that the corresponding process requirement temperature at this moment is 119°C. The difference between the current temperature of the dye vat 120°C and the process requirement temperature 119°C is 1°C. Assuming that the opening at this time is 45.1, it is necessary to reduce the firepower, that is, reduce the opening. By calculation, the adjustment amount at this time is 1.4, then the opening 45.1-1.4=target opening 43.7.

[0034] For example, at a certain moment, Figure 3 As shown, the current temperature of the dye vat (i.e., the actual temperature of the main vat) is 119.6°C. At this time, by querying the temperature target curve, it can be known that the corresponding process requirement temperature at this moment is 119°C. The difference between the current temperature of the dye vat 119.6°C and the process requirement temperature 119°C is 0.6°C. Assuming that the opening at this time is 46, it is necessary to reduce the firepower, that is, reduce the opening. By calculation, the adjustment amount at this time is 0.9, then the opening 46-0.9=target opening 45.1.

[0035] For example, at a certain moment, Figure 3 As shown, the current temperature of the dye vat (i.e., the actual temperature of the main vat) is 119.3°C. At this time, by querying the temperature target curve, it can be known that the corresponding process requirement temperature at this moment is 119°C. The difference between the current temperature of the dye vat 119.3°C and the process requirement temperature 119°C is 0.3°C. Assuming that the opening at this time is 48, it is necessary to reduce the firepower, that is, reduce the opening. By calculation, the adjustment amount at this time is 2, then the opening 48-2=target opening 46.

[0036] S104: According to the target opening, the firepower of the burner for heating the dye vat is adjusted, so that the current temperature of the dye vat is closer to or even the same as the temperature required by the process, thereby effectively improving the process quality.

[0037] According to the low-cost and low-carbon emission dyeing vat process intelligent control method of the embodiment of the present application, the temperature target curve is obtained by obtaining the process data of the dyeing vat dyeing the dyeing target, and then the target opening of the burner can be obtained according to the current temperature of the dyeing vat and the temperature target curve. Finally, according to the target opening, the firepower of the burner to heat the dyeing vat is adjusted. In this way, the temperature matching degree of the dyeing vat temperature control link is improved based on the process data, which can effectively improve the process effect. In addition, compared with the traditional steam-heated dyeing vat, the temperature control of the dyeing vat by the burner can effectively reduce energy and carbon emissions, and has the advantages of low cost and relatively more environmental protection.

[0038] In one embodiment of the present application, after adjusting the firepower of the burner to heat the dye vat according to the target opening, it also includes: obtaining the temperature matching degree according to the current temperature of the dye vat obtained each time during the process and the process requirement temperature on the corresponding temperature target curve; and evaluating the process intelligent control effect of the dye vat according to the temperature matching degree.

[0039] That is, the temperature matching degree reflects the fit between the actual temperature of the main vat and the temperature required by the process in the current production cycle. The higher the matching degree, the better the heating intelligent control effect. The matching degree of the temperature control curve = 1-WMAPE = 1-(∑(|XY| / |X|)*100%) / N, where X is the actual temperature value of the main vat, Y is the temperature value required by the process, and N is the total number of samples in the temperature rising and leveling stages in the production cycle. Figure 4 As shown, the temperature matching of the method of the embodiment of the present application is shown. Figure 4 It can be seen that the method of the embodiment of the present application can control the temperature of the dyeing vat more closely in line with the temperature required by the process, thereby effectively improving the process effect.

[0040] In one embodiment of the present application, after adjusting the firepower of the burner to heat the dye vat according to the target opening, it also includes: obtaining a gas flow reading at the beginning of the process; obtaining a gas flow reading at the end of the process; obtaining the gas usage of the process based on the gas flow reading at the beginning of the process and the gas flow reading at the end of the process; and obtaining the energy cost and carbon emissions of the process based on the gas usage.

[0041] Furthermore, the energy cost and carbon emissions of the process are obtained according to the gas usage, including: obtaining the energy cost according to the gas usage and the unit price of gas; and obtaining the carbon emissions according to the gas usage and the gas carbon emission factor.

[0042] For example: Calculation method of gas consumption P1: Record the start and end time of the production of a multi-step process in one vat (i.e. any dye vat); The corresponding gas energy consumption is calculated from the difference between the standard cumulative gas flow reading U1 of the gas meter at the start time of data collection and the standard cumulative gas flow reading U2 of the gas meter at the end time, in Nm³.

[0043] Traditional method for calculating steam consumption F1: Record the start and end time of a cylinder production with the same process temperature parameters; The corresponding gas energy consumption is calculated from the difference between D2-D1, the standard cumulative steam flow reading D1 of the steam meter at the start time of data collection and the standard cumulative steam flow reading D2 of the steam meter at the end time, in units of t.

[0044] Among them, energy cost saving: F1*steam unit price - P1*gas unit price; carbon emission saving: F1*steam carbon emission factor - P1*gas carbon emission factor. It can be clearly seen that the method of the embodiment of the present application has lower energy costs and carbon emissions compared with the traditional steam heating method. Therefore, it can effectively reduce energy and carbon emissions, and has the advantages of low cost and relatively more environmentally friendly.

[0045] Furthermore, if Figure 5 As shown, the embodiment of the present application also provides a low-cost and low-carbon dyeing vat process intelligent control system, including: an acquisition module 510, a temperature target curve determination module 520, an opening determination module 530 and a control module 540, wherein: An acquisition module 510 is used to obtain process data of dyeing a dye target by a dye vat, wherein the process data at least includes the process required temperature, heating / cooling rate and process duration; A temperature target curve determination module 520 is used to obtain a temperature target curve according to the process data; The opening determination module 530 is used to obtain the target opening of the burner according to the current temperature of the dye vat and the temperature target curve; The control module 540 is used to adjust the fire power of the burner to heat the dye vat according to the target opening.

[0046] According to the low-cost, low-carbon dyeing vat process intelligent control system of the embodiment of the present application, the temperature target curve is obtained by obtaining the process data of the dyeing vat dyeing the dyeing target, and then the target opening of the burner can be obtained according to the current temperature of the dyeing vat and the temperature target curve. Finally, according to the target opening, the firepower of the burner to heat the dyeing vat is adjusted. In this way, the temperature matching degree of the dyeing vat temperature control link is improved based on the process data, which can effectively improve the process effect. In addition, compared with the traditional steam-heated dyeing vat, the temperature control of the dyeing vat by the burner can effectively reduce energy and carbon emissions, and has the advantages of low cost and relatively more environmental protection.

[0047] It should be noted that the specific implementation method of the low-cost and low-carbon emission dye vat process intelligent control system of the embodiment of the present application is similar to the specific implementation method of the low-cost and low-carbon emission dye vat process intelligent control method of the embodiment of the present application.
