Description

Technical Field

[0001] The present application relates to the field of green energy-saving technology, and in particular to a park-based low-carbon energy-saving method and system. Background Art

[0002] With the acceleration of urbanization and industrial agglomeration, industrial parks, as concentrated areas of energy consumption and carbon emissions, are crucial to achieving their low-carbon transformation goals. Energy consumption within industrial parks primarily stems from the use of production equipment, so optimizing the use of production equipment is an effective way to achieve low-carbon and energy-saving park operations.

[0003] Currently, the optimization of production equipment usage within the park is generally based on production scheduling, which involves scheduling the required products to reduce the required operating time of production equipment, thereby reducing energy consumption and achieving low-carbon energy conservation. Currently, the production schedule of each production equipment is set by staff. Generally, production is scheduled proportionally based on the production capacity of each production equipment, so that as much as possible, all equipment stops operating at the same time to shorten the overall production time of the product. This ensures product production efficiency while reducing equipment operating time, thereby reducing energy consumption and achieving low-carbon energy conservation.

[0004] In the above-mentioned related technologies, although scheduling production of each production equipment according to production capacity can effectively shorten the production time, the energy required for each production equipment is different, and there may still be a situation where excessive energy is consumed in the production process, resulting in poor low-carbon and energy-saving effects. There is still room for improvement. Summary of the Invention

[0061] Figure 2 It is a modular flow chart of the park-based low-carbon energy-saving approach. DETAILED DESCRIPTION

[0062] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 2 It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0063] The embodiments of the present application are described in further detail below with reference to the accompanying drawings.

[0064] The present application embodiment discloses a low-carbon energy-saving method based on a park, referring to Figure 1 The process of the park-based low-carbon energy-saving method includes the following steps:

[0065] Step S100: Obtain the planned total production volume, the planned limited time, and the equipment production capacity of each production equipment.

[0066] The planned total production volume is the total number of products that need to be produced by the current production equipment as input by the staff; the planned time limit is the overall time requirement for processing the current batch of products as input by the staff, that is, the current batch of products needs to be processed within the planned time limit; the equipment production capacity is the maximum number of products that the production equipment can produce per unit time under the condition of extreme working conditions.

[0067] Step S101: randomly dividing the planned total production into individual production demands according to a preset total equipment quantity, and randomly pairing each individual production demand with each production equipment one by one to construct an overall production plan.

[0068] The total amount of equipment is the number of production equipment currently used to produce the product, and the individual production demand is the amount of products that need to be produced by a randomly divided single production equipment. The number of individual production demands is the total amount of equipment, and the sum of the individual production demands is the planned total production. The overall production plan is the overall production plan of the production equipment obtained after allocating each individual production demand to each production equipment. Since the individual production demands corresponding to each production equipment are randomly paired, there are multiple overall production plans.

[0069] Step S102: Calculate and determine the single-unit limit duration based on the equipment production capacity of each production equipment and the single-unit production demand, and randomly generate a single-unit theoretical duration from the planned limited duration and the single-unit limit duration.

[0070] The single-unit limit duration is the shortest duration required for a single production equipment to complete the processing of products with the single production demand based on its own capabilities, that is, the single production demand divided by the equipment's production capacity; the single-unit theoretical duration is the randomly generated duration for the production equipment to complete product processing.

[0071] Step S103: Calculate the unit production quantity based on the unit production demand and the theoretical duration of the unit to determine the unit production quantity, and determine the unit energy consumption based on the unit production quantity and the theoretical duration of the unit.

[0072] The unit production volume is the number of products that the production equipment needs to produce per unit time, which is determined by dividing the single-unit production demand by the single-unit theoretical duration; the single-unit energy consumption is the amount of energy that the production equipment will consume after operating at the unit production intensity for the single-unit theoretical duration. The relationship between the three can be obtained by the staff through prior experiments on the energy consumption of each production equipment, or the single-unit energy consumption can be determined through the method of steps S200-step S206.

[0073] Step S104: determining the energy consumption of the single cell with the smallest value according to a preset sorting rule, and defining the energy consumption of the single cell with the smallest value as the representative energy consumption of the single cell.

[0074] The sorting rule is a method set by the staff to sort the numerical values, such as the bubble method. The sorting rule can be used to determine the energy consumption of the single unit with the smallest value, that is, the energy required for the production equipment to consume the least under the theoretical duration of the single unit determined at this time. Therefore, it is defined as the representative consumption of the single unit to achieve the distinction between different single unit energy consumptions, which is convenient for subsequent analysis.

[0075] Step S105: performing summation calculation based on the representative consumption of each unit to determine the overall energy consumption.

[0076] The overall energy consumption is the minimum amount of energy required to execute the overall production plan, and is determined by summing the representative consumption of each unit.

[0077] Step S106: Determine the minimum overall energy consumption according to the sorting rule, define the overall production plan corresponding to the minimum overall energy consumption as an energy-saving production plan, and output the energy-saving production plan to control the operation of production equipment.

[0078] The sorting rules can be used to determine the overall energy consumption with the minimum value, that is, the amount of energy required under the corresponding overall production plan is the least. Therefore, it can be defined as an energy-saving production plan to control the operation of production equipment. At this time, the current batch of products can be effectively processed while reducing the amount of energy required to achieve low-carbon energy-saving processing. Among them, when the production equipment is controlled according to the energy-saving production plan, each production equipment operates according to the theoretical duration of each unit determined in the energy-saving production plan.

[0079] The steps to determine the energy consumption of a unit based on the unit production volume and the theoretical duration of the unit include:

[0080] Step S200: constructing a plan-limited interval with a width of the plan-limited duration on a preset time axis with the current time point as the front end point.

[0081] The time axis is a coordinate axis formed by the combination of various time points. The coordinate axis points from the time points that have passed to the time points that have not yet arrived. The time points that have passed are on the left side of the time axis, and the left side is defined as the front end of the time axis. By constructing a plan to limit the interval, the time interval in which product processing can be carried out is marked to facilitate subsequent analysis.

[0082] Step S201: Delimiting a random number of actual operation intervals of random widths within a planned limited interval, wherein the sum of the widths of the actual operation intervals is the theoretical duration of the unit.

[0083] The actual operation interval is the time interval for the production equipment to start operation as defined in the planned limited interval. The actual operation interval can be defined arbitrarily. It is only necessary to ensure that the sum of the interval widths of all actual operation intervals is the theoretical duration of the single unit to meet the normal production needs of the product.

[0084] Step S202: Demarcate the actual production interval according to the first actual operation interval and the last actual operation interval, and define the interval in the actual production interval that is not the actual operation interval as a rest area.

[0085] The actual production interval is the time interval formed by the front endpoint of the first actual operation interval and the back endpoint of the last actual operation interval, that is, the time interval during which the production equipment actually receives the corresponding production task for product production; the rest area is defined to mark the time interval during which the production equipment does not produce during the execution of the task, to facilitate subsequent analysis.

[0086] Step S203: Calculate the interval work intensity of each actual working interval based on the interval width of the actual working interval and the interval width between rest areas.

[0087] The interval operation intensity reflects the intensity of the production equipment when performing tasks in the actual operation interval. The specific determination method can refer to steps S300 to S305.

[0088] Step S204: Determine the unit energy consumption corresponding to the interval operation intensity according to the preset intensity matching relationship.

[0089] Unit energy consumption is the amount of energy required to be consumed per unit time when the production equipment operates at an interval operating intensity. Different interval operating intensities indicate different operating intensities of the production equipment, and the energy consumed at this time is also different. For example, the amount of energy consumed per unit time when the production equipment is just started up is different from the amount of energy consumed per unit time after long-term use. The intensity matching relationship between the two is determined by the staff through prior testing of each production equipment.

[0090] Step S205 : performing calculations based on each unit energy consumption and the corresponding interval width to determine the interval energy consumption.

[0091] The interval energy consumption is the amount of energy consumed by the production equipment in a single actual operation interval, and is determined by multiplying the unit energy consumption by the interval width of the corresponding actual operation interval.

[0092] Step S206: performing sum calculation based on all interval energy consumptions to determine the individual energy consumption.

[0093] The energy consumption of each unit can be obtained by adding up the energy consumption of all intervals. Due to the different demarcation of actual operation intervals, the energy consumption of each unit will also be different, so more energy consumption of each unit will be obtained. Since the minimum value of the energy consumption of each unit will be calculated later, the current step does not require additional processing of the energy consumption of each unit.

[0094] The steps of calculating the interval work intensity of each actual working interval based on the interval width of the actual working interval and the interval width of the rest area include:

[0095] Step S300: defining an interval consisting of the actual operation interval to be analyzed and the first actual operation interval as an actual analysis interval.

[0096] The actual analysis interval is the time interval formed by the rear endpoint of the actual operation interval that requires interval operation intensity analysis and the front endpoint of the first actual operation interval. For the first actual operation interval, the corresponding actual analysis interval is itself.

[0097] Step S301: Determine interval combinations from front to back in the actual analysis interval based on adjacent actual working intervals and rest areas.

[0098] The interval combination is a combination of adjacent actual operation intervals and rest areas in the actual analysis interval, in which the actual operation interval is in front and the rest area is in the back.

[0099] Step S302 : determining the back-end strength corresponding to the front-end strength, the unit production volume, and the width of the actual operation interval in the interval matching combination according to a preset first analysis matching relationship.

[0100] The back-end strength is the operating intensity that the production equipment will reach after starting to operate with the front-end strength and operating at the operating intensity per unit production volume for the width and length of the actual operating interval, that is, the fatigue condition of the equipment. The first analytical matching relationship between the four is determined in advance by the staff through multiple tests.

[0101] Step S303 : determining the rear end strength, the width of the interval between the rest areas, and the corrected strength corresponding to the preset rest parameters in the interval matching combination according to the preset second analysis matching relationship.

[0102] The corrected intensity is the operating intensity to which the production equipment will be adjusted after rest and maintenance in the rest area. The rest parameter is the degree of maintenance that the production equipment will obtain per unit time. Under different back-end strengths, interval widths between rest areas, and preset rest parameters, the corresponding corrected intensities are different. When the maintenance degree is too large, the corresponding corrected intensity is zero. The second analytical matching relationship between the four is determined in advance by the staff through multiple tests.

[0103] Step S304: using the corrected strength determined by the previous interval combination as the front end strength of the adjacent next interval combination and calculating in sequence to determine each back end strength.

[0104] The front-end strength of the first interval combination is 0, and then the rear-end strength of each actual operation interval can be calculated in turn through each corrected strength.

[0105] Step S305: Calculate the front-end strength and the rear-end strength of each actual operation interval to determine the interval operation intensity.

[0106] The interval operation intensity can be obtained by calculating the mean of the front-end strength and the back-end strength, which can better reflect the actual operation fatigue of the current production equipment in the actual operation interval.

[0107] After the actual operation range is defined, the park-based low-carbon energy-saving methods also include:

[0108] Step S400: determining whether the width of each actual working area is greater than a preset reference working width and the width of each rest area is greater than a preset reference rest width.

[0109] The benchmark operating width is the minimum length width set by the staff for the production equipment to be started up once, and the benchmark rest width is the minimum length width set by the staff for the production equipment to be rested once. The purpose of the judgment is to know whether the actual operation range currently being demarcated is reasonable.

[0110] Step S4001: If the width of each actual working area is greater than the reference working width and the width of each rest area is greater than the reference rest width, the currently determined actual working area is maintained.

[0111] When the width of each actual working area is greater than the reference working width and the width of each rest area is greater than the reference rest width, it means that the actual working area defined at this time is more reasonable. At this time, the determined actual working area can be maintained for analysis.

[0112] Step S4002: If the width of each actual working area is not greater than the reference working width and the width of each rest area is not greater than the reference rest width, the actual working area is redefined.

[0113] When there is no situation where the width of each actual working interval is greater than the benchmark working width and the width of each rest area is greater than the benchmark rest width, it means that the actual working interval is unreasonable and has no analytical significance. Therefore, the actual working interval can be redefined, thereby reducing the number of schemes that need to be analyzed, reducing the overall calculation amount, and improving data analysis efficiency.

[0114] After determining the energy consumption of a single unit, the park-based low-carbon energy-saving methods also include:

[0115] Step S500: Determine the equipment occupancy time based on the last endpoint of the actual production interval and the current time point.

[0116] The equipment occupancy time is the total time required for the equipment to complete the processing task of the product to be processed, that is, the time interval between the last endpoint of the actual production interval and the current time point.

[0117] Step S501: construct a history interval with a preset history duration on the time axis with the current time point as the end point, and calculate the usage frequency of each device in the history interval based on the device occupancy time and the history duration.

[0118] The historical duration is a fixed duration set by the staff. The historical interval is constructed to facilitate the acquisition and analysis of data within the historical duration. The usage frequency reflects the frequency of the current device receiving tasks. It is determined by dividing the sum of the device occupancy time determined in the historical interval by the historical duration.

[0119] Step S502: determining the device occupancy duration and occupancy impact parameters corresponding to the usage frequency according to a preset frequency matching relationship.

[0120] The occupancy impact parameter reflects the degree of impact caused by the current device being occupied. The more frequently the device is used, the more tasks the device needs to perform. At this time, the greater the impact of occupying the device. Similarly, the longer the device is occupied, the greater the corresponding impact. The frequency matching relationship between the three is determined by the staff through multiple tests in advance and will not be elaborated here.

[0121] Step S503: Correcting the corresponding single unit energy consumption according to the occupancy impact parameter.

[0122] By adding the individual energy consumption to the occupancy impact parameter, the individual energy consumption can be corrected, so that the appropriate individual energy consumption can be determined for data analysis.

[0123] After determining the overall energy consumption, the park-based low-carbon energy-saving methods also include:

[0124] Step S600: Determine whether there are at least two overall production plans with the same and minimum overall energy consumption.

[0125] The purpose of the judgment is to find out whether there are multiple overall production plans that meet the requirements, so as to determine the only effective production plan.

[0126] Step S6001: If there are not at least two overall production plans with the same and minimum overall energy consumption, the overall production plan with the minimum overall energy consumption is determined as the effective production plan.

[0127] When there are not at least two overall production plans with the same and minimum overall energy consumption, it means that there is only one overall production plan that meets the requirements, and it can be determined as the effective production plan.

[0128] Step S6002: If there are at least two overall production plans with the same and minimum overall energy consumption, the overall production plan with the minimum overall energy consumption is defined as the alternative production plan.

[0129] When there are at least two overall production plans with the same and minimum overall energy consumption, it means that there are multiple overall production plans that meet the requirements. At this time, they are defined as alternative production plans for identification to facilitate subsequent analysis.

[0130] Step S601: defining the equipment occupancy time with the largest value in the alternative production plans as the plan processing time.

[0131] Define the processing time of the plan to mark the time required to complete the processing of all products in the current batch, which is convenient for subsequent analysis.

[0132] Step S602: determining a single unit impact parameter according to the equipment occupancy time and the occupancy impact parameter of each production equipment in the alternative production plan.

[0133] The single impact parameter is the parameter value of the current single device that affects overall production. The larger the value, the greater the impact, and the less favorable the corresponding solution is. The single impact parameter is determined by multiplying the device occupancy time by the corresponding occupancy impact parameter.

[0134] Step S603: Calculate according to the solution processing time, all monomer influencing parameters and preset fixed calculation parameters to determine the solution selection parameters.

[0135] Fixed calculation parameters are the calculation parameters set by the staff for calculating the scheme selection parameters. Generally, there is a fixed calculation parameter corresponding to the scheme processing time, and a fixed calculation parameter corresponding to the single entity impact parameter; the scheme selection parameter is a parameter value that reflects the suitability of the scheme. The larger the value, the more suitable the selected scheme is; the scheme selection parameter is determined by multiplying the scheme processing time by the corresponding fixed calculation parameter plus the average value of all single entity impact parameters by the corresponding fixed calculation parameter, and then taking the inverse.

[0136] Step S604: determining the solution selection parameter with the largest value according to the sorting rule, and defining the alternative production solution corresponding to the solution selection parameter as the effective production solution.

[0137] The sorting rules can be used to determine the scheme selection parameter with the largest value, which means that the corresponding alternative production scheme has the best effect at this time, so it can be determined as the effective production scheme.
