[0021] Example 1

[0022] According to an embodiment of the present invention, an embodiment of a production line energy consumption detection method is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0023] Figure 1 This is a flowchart of a production line energy consumption detection method according to an embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0024] S102, obtain the current energy consumption values ​​corresponding to multiple production steps of the target production line in the current production batch;

[0025] This involves a target production line, which is a production line used to perform continuous production operations, including multiple production steps. For example, the target production line could be a dairy production line.

[0026] This involves the current production batch, which is a complete production task executed by the target production line within a predetermined time frame. Each current production batch has a unique batch identifier.

[0027] This involves multiple production steps, which are the smallest manageable operational units obtained by dividing the complete production process of the target production line according to the boundaries of operational actions. Each production step has a clear start and end time, an independent operational purpose, and a defined combination of participating equipment. For example, in a dairy production scenario, multiple production steps may include milk receiving, pasteurization, mixing, homogenization, evaporation and concentration, spray drying, and in-situ cleaning steps such as pre-rinsing, alkaline washing, intermediate rinsing, acid washing, and final rinsing.

[0028] This includes the current energy consumption value, which is the total amount of electricity actually consumed by each production step in the target production line during its respective operation period in the current production batch.

[0029] S104, determine the energy consumption mode corresponding to multiple production steps respectively, wherein the energy consumption mode includes either the first mode or the second mode, the first mode is the production mode corresponding to the first correlation relationship, the second mode is the production mode corresponding to the second correlation relationship, the first correlation relationship is used to characterize the correlation relationship between step energy consumption and production time under the corresponding production step, and the second correlation relationship is used to characterize the correlation relationship between the corresponding production step and the step output.

[0030] This involves energy consumption patterns, which are used to characterize the energy consumption impact of production steps in a target production line, reflecting the core energy consumption influencing factors for each type of production step. These energy consumption patterns include either a first pattern or a second pattern, with each production step corresponding to one of these energy consumption patterns.

[0031] Among them, the first mode is the production mode corresponding to the first correlation. In this mode, the energy consumption of the step sequence is dominated by the production time and is not directly related to the output of the step sequence.

[0032] This involves a first correlation, which is the relationship between step energy consumption and production time under a corresponding production step. Specifically, in the first correlation, the step energy consumption of a production step is driven by production time and is unrelated to the step output.

[0033] This involves a second mode, which is the production mode corresponding to the second correlation. In this mode, the energy consumption of the production step is dominated by the output of the production step.

[0034] This involves a second correlation, which is the relationship between step energy consumption and step output in a corresponding production step. Specifically, in the second correlation, the step energy consumption of a production step is driven by the step output.

[0035] This includes step output, which is the output quantity of the target production line in the current production batch, related to the corresponding production step.

[0036] This involves production time, which is the runtime of the corresponding production step.

[0037] S106, Based on the energy consumption modes corresponding to multiple production steps, determine the reference energy consumption values ​​corresponding to the multiple production steps respectively;

[0038] This involves a reference energy consumption value, which is the total electrical energy that a production step should consume under ideal or baseline conditions, determined within the energy consumption mode corresponding to that production step. This reference energy consumption value serves as a benchmark for judging whether the energy consumption level of the corresponding production step is normal in the current production batch.

[0039] S108, determine the energy consumption deviation rate between the current energy consumption value and the corresponding reference energy consumption value for multiple production steps;

[0040] This includes the energy consumption deviation rate, which measures the degree of deviation of the current energy consumption value of the corresponding production step in the current production batch from the reference energy consumption value.

[0041] S110, based on the energy consumption deviation rate between the current energy consumption value and the corresponding reference energy consumption value corresponding to multiple production steps, determine the energy consumption detection result of the target production line.

[0042] This involves energy consumption testing results, which characterize the energy consumption status of the target production line in the current production batch. For example, the energy consumption testing results include at least one of the following: abnormal step sequence identification information, energy consumption deviation rate information of abnormal step sequence, energy consumption deviation value information of abnormal step sequence, current energy consumption value information of abnormal step sequence, reference energy consumption value information of abnormal step sequence, energy saving information of abnormal step sequence, and energy consumption testing report of the target production line in the current production batch.

[0043] Through steps S102-S110 above, by obtaining the current energy consumption values ​​corresponding to multiple production steps in the current production batch of the target production line, the actual power consumption data of each production step can be provided for subsequent deviation analysis. By determining the energy consumption mode corresponding to each of the multiple production steps, the corresponding reference energy consumption value calculation logic can be automatically matched according to the energy consumption driving characteristics of each production step (production time driven or step output driven), ensuring that the reference energy consumption value is consistent with the actual energy consumption influencing factors of the production step, and avoiding the energy consumption of steps with different characteristics due to the use of a single energy consumption benchmark. The deviation was miscalculated; by determining the reference energy consumption value corresponding to each of the multiple production steps based on their respective energy consumption patterns, each production step can obtain a theoretical energy consumption benchmark that matches its energy consumption driving factors. Furthermore, the energy consumption deviation rate between the current energy consumption value and the corresponding reference energy consumption value for each of the multiple production steps can be determined, which can quantify the degree to which the actual energy consumption of each production step deviates from the benchmark. Finally, based on this energy consumption deviation rate, the granularity of energy consumption detection can be refined to the step level and abnormal steps can be accurately identified, thereby ensuring the accuracy of the energy consumption detection results of the target production line.

[0044] As an optional embodiment, determining reference energy consumption values ​​corresponding to multiple production steps based on their respective energy consumption modes includes: determining a configuration association matrix corresponding to the target production line, wherein the configuration association matrix is ​​used to characterize the configuration association relationship between production equipment and production steps in the target production line, with rows of the configuration association matrix corresponding to different production equipment and columns corresponding to different production steps; based on the configuration association matrix, determining multiple energy-consuming devices corresponding to the multiple production steps from among the multiple production equipment in the target production line, wherein the multiple energy-consuming devices are production equipment whose configuration association relationship with the corresponding production steps in the configuration association matrix is ​​a predetermined association relationship; and determining reference energy consumption values ​​corresponding to the multiple production steps based on the energy consumption modes and the multiple energy-consuming devices.

[0045] This involves a configuration association matrix, which is used to characterize the configuration association relationships between production equipment and production steps in a target production line. The rows of the configuration association matrix correspond to different production equipment, and the columns correspond to different production steps. The value of each element in the configuration association matrix indicates whether the production equipment in that row is configured to run in the production step sequence of that column. For example, in the configuration association matrix, the first row corresponds to the first production equipment, the first column corresponds to the first production step, and the value of the element at the intersection of the first row and the first column indicates whether the first production equipment is configured to run in the first production step sequence. In the configuration association matrix, each element's value includes either a first value or a second value. A first value (e.g., 1) indicates that the production equipment in that row is configured to run in the production step sequence of that column, and a second value (e.g., 0) indicates that the production equipment in that row is not configured to run in the production step sequence of that column.

[0046] This involves production equipment, which are electrical devices that participate in the production process of the target production line and consume electrical energy. The production equipment includes motors (such as feed pump motors, return pump motors, material pump motors, shear pump motors, etc.), and each piece of production equipment has a corresponding rated power.

[0047] This involves energy-consuming equipment, which refers to production equipment whose configuration association relationship with the corresponding production step is predetermined in the configuration association matrix. The predetermined association relationship means that the element in the configuration association matrix takes the first value (e.g., 1), indicating that the energy-consuming equipment is configured to run in the corresponding production step. Energy-consuming equipment refers to each production device participating in the operation of the corresponding production step.

[0048] By determining the configuration association matrix corresponding to the target production line, the configuration association between each production equipment and different production steps can be accurately represented in a matrix manner, avoiding the tediousness and omissions of manually sorting out the participation of each equipment. Based on this configuration association matrix, multiple energy-consuming devices corresponding to multiple production steps are identified from multiple production equipment in the target production line (i.e., production equipment with a predetermined configuration association relationship with the corresponding production steps). This allows for accurate screening of the specific energy-consuming devices configured to operate in each production step from all production equipment included in the target production line, avoiding the miscalculation of production equipment not configured to operate in the current production step into the energy consumption calculation of that production step, while also avoiding the omission of production equipment configured to operate in the current production step. Based on the energy consumption modes and corresponding energy-consuming devices for each of the multiple production steps, reference energy consumption values ​​are determined for each of the multiple production steps. This ensures that the reference energy consumption value for each production step is determined solely by the energy-consuming devices configured to operate in that production step and their corresponding energy consumption modes, ensuring that the calculation basis of the reference energy consumption value is consistent with the actual energy consumption driving factors. This avoids deviations of the reference energy consumption value from the actual process state due to the inclusion or omission of production equipment not configured to operate in the current production step.

[0049] As an optional embodiment, based on the energy consumption modes and energy-consuming devices corresponding to multiple production steps, a reference energy consumption value corresponding to each of the multiple production steps is determined, including: for a target step among the multiple production steps, the reference energy consumption value corresponding to the target step is determined in the following way: when the energy consumption mode corresponding to the target step is the first mode, the target runtime of the target step is determined; the device energy consumption index corresponding to each of the multiple energy-consuming devices corresponding to the target step is determined; based on the target runtime and the device energy consumption index corresponding to each of the multiple energy-consuming devices corresponding to the target step, the reference energy consumption value corresponding to the target step is determined.

[0050] This involves a target step sequence, which is any one of multiple production steps.

[0051] This involves a target runtime, which is the preset runtime of the target step sequence when the energy consumption mode corresponding to the target step sequence is the first mode. The target runtime is used to calculate the reference energy consumption value of the target step sequence in the first mode.

[0052] This involves the equipment energy consumption index, which characterizes the energy consumption level of energy-consuming equipment per unit of operating time. For example, the equipment energy consumption index can be represented by the rated power of the energy-consuming equipment. Specifically, when the energy consumption mode corresponding to the target step sequence is the first mode, the equipment energy consumption index corresponding to the multiple energy-consuming devices corresponding to the target step sequence is the rated power corresponding to the multiple energy-consuming devices corresponding to the target step sequence.

[0053] By determining the target runtime of a target step in multiple production steps, assuming the energy consumption mode corresponding to the target step is the first mode, we can obtain the benchmark runtime that the target step should consume under ideal conditions. Then, we can determine the energy consumption index of each energy-consuming device corresponding to the target step, quantifying the energy consumption level of each device participating in the target step within a unit runtime. Based on the target runtime and the energy consumption indices of each device, we can determine a reference energy consumption value corresponding to the target step, coupling the target runtime with the unit-time energy consumption level of each device. This enables accurate calculation of the theoretical energy consumption of the target step, avoiding deviations of the reference energy consumption value from the actual energy consumption characteristics of the step due to calculation methods inconsistent with the energy consumption driving factors of the step.

[0054] As an optional embodiment, based on the energy consumption modes and energy-consuming devices corresponding to multiple production steps, a reference energy consumption value corresponding to each of the multiple production steps is determined, including: for a target step among the multiple production steps, the reference energy consumption value corresponding to the target step is determined in the following way: when the energy consumption mode corresponding to the target step is the second mode, the current running time, current output, and reference output corresponding to the target step are determined, wherein the current running time is the cumulative running time under the current production batch; based on the current running time, reference output, and the multiple energy-consuming devices corresponding to the target step, the step energy consumption index corresponding to the target step is determined; based on the step energy consumption index corresponding to the target step and the current output, the reference energy consumption value corresponding to the target step is determined.

[0055] This includes the current runtime, which is the cumulative runtime of the target step sequence from start to finish in the current production batch.

[0056] This includes the current output, which is the actual output of the product corresponding to the target step in the current production batch.

[0057] This involves a reference production volume, which is the production volume of the selected benchmark batch as a reference.

[0058] This includes the step sequence energy consumption index, which is the energy consumption level of the target step sequence per unit of production output in the current production batch.

[0059] By associating the cumulative runtime and actual output of the current production batch with the reference output of the historical benchmark batch when the target step is in the second energy consumption mode, and combining this with the sum of the rated power of all energy-consuming equipment associated with the step to calculate the step energy consumption index, this index reflects the energy consumption level that should be consumed per unit output under the current operating conditions (based on the current cumulative runtime and current output). Multiplying this index by the current output to derive the reference energy consumption value allows the actual value of the current output to directly participate in the final conversion of theoretical energy consumption, avoiding the substitution of the actual output of the current batch with a fixed output or design conditions. This ensures that the calculated reference energy consumption value is consistent with the actual operating status of the current batch, accurately anchoring the actual energy consumption level per unit output of the step under the current output, and fully adapting to the step operation characteristics of linear energy consumption with output under the second mode.

[0060] As an optional embodiment, the reference output is determined in the following manner: determining the batch difference between the current production batch and the predetermined production batch; based on the batch difference between the current production batch and the predetermined production batch, determining an output selection operation and executing the output selection operation to obtain the reference output, wherein the output selection operation includes any of the following: if the batch difference meets a predetermined condition, determining the reference output from the batch outputs corresponding to multiple target batches, wherein the multiple target batches include the current production batch and multiple historical production batches; if the batch difference does not meet the predetermined condition, using the batch output of the previous production batch corresponding to the current production batch as the reference output.

[0061] This involves a pre-defined production batch, which is a pre-set production batch identifier used for reference and comparison.

[0062] This involves batch difference, which is the difference between the current production batch and the planned production batch.

[0063] This involves a production selection operation, which is the action of selecting a reference production volume.

[0064] This involves predetermined conditions, which are pre-set thresholds or rules for determining batch difference values, used to decide how to determine the reference output. For example, predetermined conditions include batch differences being multiples of a predetermined number. Taking the first batch as an example, the predetermined conditions include: batch differences being multiples of 5, used to update the reference output every 5 batches.

[0065] This involves multiple target batches, which are a set of production batches used to determine reference output, including current production batches and multiple historical production batches.

[0066] This involves batch production volume, which refers to the actual output of the product corresponding to the production batch.

[0067] This involves the previous production batch, which is the production batch that precedes the current production batch in terms of time. Its batch output can be directly used as the source of the reference output value.

[0068] By determining the batch difference between the current production batch and the planned production batch, the positional offset of the current production batch relative to the baseline can be quantified, providing a basis for the dynamic selection of the reference output. Based on this batch difference, the output selection operation is determined and executed. When the batch difference meets the predetermined conditions, the reference output can be determined from the batch outputs corresponding to multiple target batches, including the current production batch and multiple historical production batches. This enables the periodic updating of the reference output at key nodes, ensuring that the reference output can reflect the recent optimal or most stable production level. When the batch difference does not meet the predetermined conditions, the batch output of the previous production batch corresponding to the current production batch is used as the reference output. This maintains the continuity and stability of the reference output at non-update nodes, avoiding excessive fluctuations in the reference energy consumption value caused by frequent changes. Thus, the determination of the reference output in the second mode has both the flexibility of timely updates and the stability during the transition period, avoiding the problem of the reference output remaining fixed for a long time and gradually deviating from the actual production level, or being updated too frequently and introducing noise interference.

[0069] As an optional embodiment, the energy consumption detection result of the target production line is determined based on the energy consumption deviation rate between the current energy consumption value and the corresponding reference energy consumption value corresponding to each of the multiple production steps. This includes: determining the deviation threshold corresponding to each of the multiple production steps; determining the step response operation corresponding to each of the multiple production steps based on the energy consumption deviation rate between the current energy consumption value and the corresponding reference energy consumption value corresponding to each of the multiple production steps, and the deviation threshold corresponding to each of the multiple production steps; and determining the production line response operation of the target production line based on the step response operation corresponding to each of the multiple production steps, wherein the energy consumption detection result includes the production line response operation.

[0070] This involves a deviation threshold, which is a pre-set energy consumption deviation rate judgment boundary value for each production step. It is used to determine what response operation should be triggered for that step under the current deviation rate. Different production steps can be configured with different deviation thresholds.

[0071] This involves step-by-step response operations, which are actions performed by a single production step when its energy consumption deviation rate exceeds a corresponding deviation threshold. For example, these operations may include triggering / not triggering an alarm for the step, recording the step's deviation data, or marking the step as pending inspection.

[0072] This involves production line response operations, which are execution actions at the overall target production line level determined by summarizing the response operations corresponding to multiple production steps. For example, these production line response operations include triggering / not triggering a comprehensive alarm for the entire production line, generating an energy consumption detection report containing all abnormal steps, or sending adjustment instructions to the production line control system.

[0073] By setting independent deviation thresholds for each production step, different steps can independently determine their own energy consumption status within their respective allowable deviation ranges, avoiding misjudgments caused by a uniform threshold leading to some steps being too lenient or too strict. Furthermore, by comparing the energy consumption deviation rate between the current energy consumption value and the reference energy consumption value of each step with its respective deviation threshold, a step response operation that precisely corresponds to the degree of deviation for each step can be generated, preventing all steps from adopting the same response strategy and masking individual differences between steps. Finally, by summarizing and comprehensively judging the step response operations of all steps, the response results of each step can be coordinated at the level of the entire production line, forming a unified production line response operation.

[0074] As an optional embodiment, after determining the energy consumption detection results of the target production line based on the energy consumption deviation rate between the current energy consumption value and the corresponding reference energy consumption value corresponding to multiple production steps, the method further includes: determining the process to be improved from multiple production steps based on the energy consumption detection results of the target production line; determining the adjustable energy consumption value corresponding to the process to be improved; and adjusting the energy consumption of the process to be improved according to the adjustable energy consumption value.

[0075] This involves processes that need improvement, which are selected from multiple production steps that require energy consumption adjustments. For example, the processes to be improved could be those with energy consumption deviation rates exceeding a corresponding deviation threshold, or several steps with the highest energy consumption deviation rates.

[0076] This includes adjustable energy consumption values, which represent the amount of energy reduction or target adjustment that the process to be improved can achieve under current conditions by adjusting its operation.

[0077] By locating the process to be improved from multiple production steps based on the energy consumption monitoring results of the target production line, the adjustment scope can be narrowed down from the entire production line to the specific process to be improved, avoiding unnecessary adjustments to non-abnormal processes. By determining the adjustable energy consumption value corresponding to the process to be improved, the specific adjustment range of the process can be quantified, providing accurate target parameters for adjustment operations and avoiding under- or over-adjustment due to experience-based estimations. By adjusting the energy consumption of the process to be improved according to the adjustable energy consumption value, unreasonable energy consumption can be avoided in a timely manner.

[0078] Based on the above embodiments and optional embodiments, an optional implementation method is provided, which is described in detail below.

[0079] In related technologies, energy consumption monitoring of production lines is necessary to prevent unnecessary energy waste caused by continuous operation under abnormal conditions, and to provide reliable data support for refined energy consumption management in subsequent production operations. However, in these technologies, there is a technical problem of inaccurate energy consumption monitoring of production lines.

[0080] There is currently no effective solution to the above problems.

[0081] In view of this, an optional embodiment of the present invention provides a method for detecting energy consumption in a production line, which can effectively solve the above-mentioned technical problems.

[0082] S1, obtain the current energy consumption values ​​corresponding to multiple production steps of the target production line in the current production batch;

[0083] S2, determine the energy consumption mode corresponding to multiple production steps respectively, wherein the energy consumption mode includes either the first mode or the second mode. The first mode is the production mode corresponding to the first correlation relationship, and the second mode is the production mode corresponding to the second correlation relationship. The first correlation relationship is used to characterize the correlation relationship between step energy consumption and production time under the corresponding production step, and the second correlation relationship is used to characterize the correlation relationship between the corresponding production step and the step output.

[0084] Example:

[0085] For production steps Select the energy consumption mode based on the label of the product item or work section it belongs to. :

[0086]

[0087] If the corresponding production step sequence is the first associated relationship, such as the product type or work section being a fixed target, then the first mode is adopted. If the corresponding production sequence is a second correlation, such as based on output (i.e., output is the main factor affecting energy consumption), then the second mode is adopted. .

[0088] S3, based on the energy consumption modes corresponding to multiple production steps, determines the reference energy consumption values ​​corresponding to the multiple production steps respectively;

[0089] Specifically, S3 includes:

[0090] A configuration association matrix corresponding to the target production line is determined. This matrix characterizes the configuration association relationships between production equipment and production steps within the target production line. Rows in the configuration association matrix correspond to different production equipment, and columns correspond to different production steps. Based on the configuration association matrix, multiple energy-consuming devices corresponding to multiple production steps are identified from among the production equipment in the target production line. These energy-consuming devices are those whose configuration association relationship with their corresponding production steps is predetermined in the configuration association matrix. Based on the energy consumption patterns corresponding to the multiple production steps and the multiple energy-consuming devices, reference energy consumption values ​​corresponding to the multiple production steps are determined.

[0091] Specifically, for a target step among multiple production steps, the reference energy consumption value corresponding to the target step is determined in the following way:

[0092] When the energy consumption mode corresponding to the target step sequence is the first mode, determine the target runtime of the target step sequence; determine the device energy consumption index corresponding to each of the multiple energy-consuming devices corresponding to the target step sequence; and determine the reference energy consumption value corresponding to the target step sequence based on the target runtime and the device energy consumption index corresponding to each of the multiple energy-consuming devices corresponding to the target step sequence.

[0093] Taking the first mode as an example, the theoretical energy consumption model with a fixed target duration is as follows:

[0094] This mode is suitable for production steps with relatively fixed operation times and no direct relationship to output, such as the various steps of CIP cleaning (pre-rinse, alkaline wash, intermediate rinse, acid wash, final rinse). CIP cleaning is an in-situ technology that automates internal cleaning of equipment without disassembly, using circulating acid, alkali, hot water, and disinfectants. The cleaning time for pipelines is determined by the cleaning process, not by output, as shown in the formula:

[0095]

[0096] in:

[0097] Production sequence in the first mode The electrical energy that should be consumed under ideal conditions, measured in kilowatt-hours (kWh). The representative used the first mode, which is a fixed target duration;

[0098] Target runtime of the production sequence, production sequence The preset optimal operation time, in hours;

[0099] Summing over the motors involves adding up the rated power of all the motors involved in this production step. This represents the total number of production steps.

[0100] Configure the correlation matrix (or simply correlation matrix), with values ​​of 0 or 1, where 1 represents the motor. Participating in the production process 0 indicates non-participation;

[0101] Equipment energy consumption index, expressed in terms of motor rated power, in kilowatts, is used as the theoretical energy consumption.

[0102] For example:

[0103] Alkaline washing process steps in CIP cleaning Target runtime =0.25 hours, the participating motors are:

[0104] Feed pump: =15KW; Reflux pump: =11KW;

[0105] Material pump: =2.2KW; Shear pump: =5.5KW;

[0106] Alkaline washing process steps in CIP cleaning Energy consumption in the first mode :

[0107]

[0108] Specifically, for a target step among multiple production steps, the reference energy consumption value corresponding to the target step is determined in the following way:

[0109] When the energy consumption mode corresponding to the target step sequence is the second mode, determine the current running time, current output, and reference output corresponding to the target step sequence, where the current running time is the cumulative running time under the current production batch; based on the current running time, reference output, and multiple energy-consuming devices corresponding to the target step sequence, determine the step sequence energy consumption index corresponding to the target step sequence; based on the step sequence energy consumption index corresponding to the target step sequence and the current output, determine the reference energy consumption value corresponding to the target step sequence.

[0110] The second model, based on the theoretical energy consumption per ton of time and output, is used as an example:

[0111] This mode is applicable to production steps where energy consumption and output are directly related, such as the sterilization and concentration steps of the evaporator and the drying steps of the drying tower.

[0112] First, we need to calculate how much electricity this production step consumes to process 1 ton of product under ideal conditions. The formula is:

[0113]

[0114] in:

[0115] Production step sequence energy consumption index, also known as the theoretical energy consumption coefficient per ton of production step sequence, refers to the energy consumption index of the production step sequence. The electrical energy consumed per ton of product processed under optimal operating conditions is expressed in kWh / ton.

[0116] The baseline total running time is used to select the best batch from historical data and record the production sequence. Total cumulative operating time, in hours;

[0117] The sum of the rated power of all motors participating in this production step, in kW;

[0118] Benchmark output, also known as reference output, is the output of the selected optimal batch, measured in tons. The same batch.

[0119] The theoretical energy consumption is calculated based on actual output, using the following formula:

[0120]

[0121] in:

[0122] The theoretical energy consumption of the production steps in the second mode, in the current batch, is as follows: Theoretically required electrical energy, in kWh, superscript. The representative used the second model, which is based on output correlation;

[0123] Actual output, also known as current output, represents the actual output of the current batch, in tons;

[0124] Theoretical energy consumption coefficient per ton, in kWh / ton.

[0125] For example:

[0126] Taking the concentration production sequence of the evaporator as an example, we selected the most stable batch in historical data as the benchmark. The cumulative running time of the concentration production sequence in this shift was 6 hours, the total rated power of the motors participating in the concentration production sequence was 80KW, and the total output of this batch was 50 tons.

[0127] Calculated theoretical energy consumption coefficient per ton for:

[0128]

[0129] Under optimal operating conditions, the concentration production process consumes 9.6 kWh of electricity per ton.

[0130] Theoretical energy consumption for the new batch:

[0131] For example, if a certain batch produces 60 tons today, the theoretical energy consumption of this production step is... Today, 60 tons of product were produced. Under optimal operating conditions, this production sequence should consume 576 kilowatt-hours of electricity. If the actual consumption exceeded this value, the cause needs to be investigated.

[0132] Specifically, the reference yield is determined in the following manner:

[0133] Determine the batch association between the current production batch and the planned production batch; based on the batch difference between the current production batch and the planned production batch, determine the output selection operation and execute the output selection operation to obtain the reference output. The output selection operation includes any of the following: if the batch difference meets the predetermined conditions, determine the reference output from the batch outputs corresponding to multiple target batches, where the multiple target batches include the current production batch and multiple historical production batches; if the batch difference does not meet the predetermined conditions, use the batch output of the previous production batch corresponding to the current production batch as the reference output.

[0134] Example:

[0135] Continuously monitor the energy consumption of each production step and set rules to automatically trigger baseline updates. For example, if the actual energy consumption of a certain production step is consistently lower than the current theoretical value for a certain number of consecutive batches, and the product quality of these batches is qualified with no equipment fault alarms.

[0136] Based on the above, the benchmark can be automatically adapted to the current equipment and operating level, avoiding the problem of "theoretical values ​​becoming outdated". Moreover, whenever the operating level steadily improves, the benchmark will automatically follow, forming a virtuous cycle of "optimization → meeting the standard → updating the benchmark → further optimization". In addition, there is no need for manual adjustment of parameters periodically.

[0137] S4, determine the energy consumption deviation rate between the current energy consumption value and the corresponding reference energy consumption value for multiple production steps;

[0138] Example:

[0139] Energy consumption deviation between the current energy consumption value and the corresponding reference energy consumption value:

[0140]

[0141] in:

[0142] Production step sequence energy consumption deviation, production step sequence The difference between actual energy consumption and theoretical energy consumption, expressed in kWh;

[0143] The actual power consumption was higher than the theoretical value, indicating that this production step used more electricity, which may indicate an abnormality.

[0144] The actual result is lower than the theoretical result, which means the operation is better than the set standard. Keep it up.

[0145] Actual energy consumption of each production step.

[0146] Calculate the energy consumption deviation rate of the production step sequence:

[0147]

[0148] in:

[0149] Energy consumption deviation rate reflects the degree of deviation.

[0150] S5. Based on the energy consumption deviation rate between the current energy consumption value and the corresponding reference energy consumption value corresponding to multiple production steps, determine the energy consumption detection result of the target production line.

[0151] Specifically, S5 includes:

[0152] Determine the deviation thresholds corresponding to multiple production steps respectively; based on the energy consumption deviation rate between the current energy consumption value and the corresponding reference energy consumption value corresponding to multiple production steps respectively, and the deviation thresholds corresponding to multiple production steps respectively, determine the step response operation corresponding to multiple production steps respectively; based on the step response operation corresponding to multiple production steps respectively, determine the production line response operation of the target production line, wherein the energy consumption detection result includes the production line response operation.

[0153] Example:

[0154] Set a deviation rate threshold. (Configurable parameters, such as) ):

[0155]

[0156] in:

[0157] : Abnormal alarm flag, 1 indicates that the step sequence is marked as an abnormally high energy consumption step sequence and an alarm is pushed.

[0158] Specifically, after determining the energy consumption detection results of the target production line based on the energy consumption deviation rate between the current energy consumption value and the corresponding reference energy consumption value for multiple production steps, the process also includes:

[0159] Based on the energy consumption monitoring results of the target production line, identify the process to be improved from multiple production steps; determine the adjustable energy consumption value corresponding to the process to be improved; and adjust the energy consumption of the process to be improved according to the adjustable energy consumption value.

[0160] Example:

[0161] For steps marked as abnormal, if it is the first mode, the amount of electricity wasted can be quantitatively calculated using the following formula:

[0162]

[0163] in:

[0164] Adjustable energy consumption value, which means energy saving. If the operation time of this step is shortened to the target value, theoretically some electricity can be saved, in kWh.

[0165] : Actual duration of the step sequence;

[0166] : Step sequence target duration;

[0167] Excess time: The actual time spent exceeding the target.

[0168] : The sum of the rated power of the motors participating in the step sequence.

[0169] The following description, with specific examples, will further illustrate this point.

[0170] (1) First mode, namely, theoretical energy consumption calculation for fixed target duration:

[0171] Evaporator production steps As an example, target runtime =0.25 hours, the participating motors are:

[0172] Feed pump: =15KW; Material pump: =11KW;

[0173] Condensate pump: =2.2KW; Discharge pump: =5.5KW;

[0174] Evaporator production steps Power consumption in the first mode :

[0175]

[0176] (2) Second mode, theoretical energy consumption per ton of output per hour:

[0177] Taking the concentration step of the evaporator as an example, we selected the batch with the most stable production in the historical data as the benchmark. The cumulative running time of the concentration step in this shift was 6 hours, the total rated power of the motors participating in the concentration step was 80KW, and the total output of this batch was 50 tons.

[0178] The calculated theoretical energy consumption coefficient per ton is: ;

[0179] Under optimal operating conditions, the concentration step consumes 9.6 kWh of electricity per ton.

[0180] Theoretical energy consumption for the new batch:

[0181] For example, if a batch produces 60 tons today, the theoretical energy consumption for this step is... Today, 60 tons of product were produced. Under optimal operating conditions, this step should have used 576 kilowatt-hours of electricity.

[0182] The above optional implementation methods can achieve at least the following beneficial effects:

[0183] (1) By obtaining the current energy consumption values ​​corresponding to multiple production steps in the current production batch of the target production line, the energy consumption mode corresponding to the multiple production steps is determined. Based on the energy consumption mode corresponding to the multiple production steps, the reference energy consumption value corresponding to the multiple production steps is determined. The energy consumption deviation rate between the current energy consumption value and the corresponding reference energy consumption value corresponding to the multiple production steps is determined. Based on the energy consumption deviation rate corresponding to the multiple production steps, the energy consumption detection result of the target production line is determined. It can automatically match the energy consumption mode that is compatible with its energy consumption characteristics for each production step and obtain the corresponding reference energy consumption value. It ensures that the reference energy consumption value is consistent with the actual energy consumption driving factors of the production step. It avoids the incorrect calculation of energy consumption deviation of different characteristic steps due to the use of a single energy consumption benchmark. It realizes the refinement of energy consumption detection granularity to the step level and accurate identification of abnormal steps, thereby ensuring the accuracy of the energy consumption detection result of the production line. It solves the technical problem of inaccurate energy consumption detection of the production line in the related technologies.

[0184] (2) By determining the configuration association matrix corresponding to the target production line, multiple energy-consuming devices corresponding to multiple production steps are identified from multiple production equipment in the target production line based on the configuration association matrix. Based on the energy consumption mode and multiple energy-consuming devices corresponding to multiple production steps, reference energy consumption values ​​corresponding to multiple production steps are determined. The configuration association matrix can accurately lock the energy-consuming devices that actually participate in the operation of each production step, ensuring that the calculation of the reference energy consumption value only includes the power of the equipment actually associated with the step, avoiding the miscalculation of the power of equipment that does not participate in the operation of the step into the reference energy consumption value, thereby ensuring that the reference energy consumption value of each production step strictly corresponds to its actual equipment configuration, and achieving the accuracy of the reference energy consumption value calculation.

[0185] (3) By determining the target runtime of the target step in multiple production steps under the condition that the energy consumption mode corresponding to the target step is the first mode, the benchmark of the running time that the target step should consume under ideal conditions can be obtained; then, the energy consumption index of the multiple energy-consuming devices corresponding to the target step can be determined, and the energy consumption level of each energy-consuming device participating in the target step within a unit runtime can be quantified; based on the target runtime and the energy consumption index of the multiple energy-consuming devices, the reference energy consumption value corresponding to the target step can be determined, and the target runtime can be coupled with the unit time energy consumption level of each energy-consuming device, so as to realize the accurate calculation of the theoretical energy consumption of the target step and avoid the reference energy consumption value deviating from the real energy consumption characteristics of the step due to the use of a calculation method that is inconsistent with the energy consumption driving factors of the step.

[0186] (4) When the target step is in the second energy consumption mode, the cumulative running time and actual output of the current production batch are associated with the reference output of the historical benchmark batch, and the step energy consumption index is calculated by combining the rated power of all energy-consuming equipment associated with the step. This index reflects the energy consumption level that should be consumed per unit output under the current operating conditions (based on the current cumulative running time and current output). The reference energy consumption value is then derived by multiplying the index by the current output. This allows the actual value of the current output to directly participate in the final conversion of theoretical energy consumption, avoiding the substitution of the actual output of the current batch with a fixed output or design conditions. This ensures that the calculation result of the reference energy consumption value is consistent with the actual operating state of the current batch, accurately anchors the actual energy consumption level per unit output of the step under the current output, and fully adapts to the step operation characteristics where energy consumption changes linearly with output under the second mode.
