The embodiment of the invention provides a refined energy management and control method, referring to fig. 1, the present embodiment is particularly suitable for a production mode of a semi-automatic or fully automatic production line, which is convenient for monitoring, metering and deciding of a remote distributed monitoring unit, the method can be executed by a refined energy management and control system, and the system can be realized by adopting a software and/or hardware mode, the method comprises the following steps:
step S100, acquiring historical energy consumption spot inspection data sets of one or more remote distributed monitoring devices associated with a production chain by a plurality of manufactured products through at least one workshop in the production and manufacturing process;
in the specific embodiment of the invention, the manufactured product can be automobiles, foods, wine, beverages, refined tea, tobacco products, medical equipment, transportation equipment, electric machinery and equipment, electronic products, printed matters, nonferrous metal smelting and the like.
Preferably, the manufacture is particularly suitable for the automobile manufacturing industry, for example, the production and manufacturing process of automobile manufacturing is carried out through a production chain of a stamping workshop, a welding workshop, a coating workshop and a final assembly workshop, wherein the workshop can comprise a plurality of production lines, and each production line comprises a plurality of remote distributed monitoring devices associated with production.
In a specific embodiment of the present invention, the remote distributed monitoring device includes an energy monitoring sensor, a remote communication device, a storage device and a controller, where the remote distributed monitoring device is disposed at an input end of one or more production executing devices associated with at least one workshop in a production and manufacturing process, and is used to store the historical energy consumption spot inspection data set of the production executing device and collect real-time energy consumption spot inspection data, and the remote communication device uploads the data to a management and control cloud server through a convergence gateway; and the control cloud server transmits the control recommendation strategy to the controller according to the uploading data, and the controller is used for controlling the operation parameters of the corresponding production execution equipment according to the control recommendation strategy.
Preferably, the remote distributed monitoring device may further include a data preprocessing device, where a historical energy consumption point data set and real-time energy consumption point detection data may be pre-formatted according to a user-defined field before the acquisition process, and the field may be expanded, where in general, in the prior art, the field monitored by the monitoring unit is only time and energy consumption, and according to the subunit, a feature monitoring field such as start-stop record and fault code may be added according to a user requirement, which is beneficial to a subsequent management and control decision.
The remote distributed monitoring device may be used to monitor an electric device, a water supply device, a heating device, a functional device, a gas supply device, etc., and the application range thereof may be set according to the actual production, which is not further limited in the present invention.
It can be understood that the above three-level remote monitoring architecture adopting the distributed monitoring unit-convergence gateway-management and control cloud server can be used in combination by adopting a plurality of existing communication modes such as 2G/3G/4G/5G, WIFI, ZIGBEE, bluetooth and the like in order to avoid the influence of interference and faults on a single communication mode.
Step S110, splitting the historical energy consumption spot inspection data set into a management subset of a plurality of time scales under a plurality of use/application types, and determining a corresponding energy consumption standard according to the management subset, wherein the management subset is measured by the remote distributed monitoring equipment and is controlled by energy sources;
it can be appreciated that in general, a single energy consumption management KPI in a factory appears to be measurable, but is a KPI converted from a nominal value of power consumption, and is not hooked precisely with specific equipment, functional use and time difference, so that precise management and control measures cannot be implemented.
In another embodiment of the present invention, the process of splitting the historical energy consumption spot inspection dataset into a plurality of time scale management subsets under a plurality of usage/usage types, and determining the corresponding energy consumption standard according to the management subsets may refer to fig. two, which is a control recommendation policy flowchart provided by the present invention, and the method steps include:
step 200: correlating the historical energy consumption spot inspection data set with a manufactured product in the production and manufacturing process to obtain a historical energy consumption data correlation group corresponding to the manufactured product;
in order to accurately determine the standard energy consumption of the specific product, the historical energy consumption data of the specific product is correlated, namely, the energy consumption data of the production equipment corresponding to each workshop in the whole production period of the product is obtained, and further, the historical energy consumption data can be the production energy consumption data corresponding to each workshop on the production line corresponding to each workshop according to the whole production period of the product.
The association group format can be { production period, product type and number, workshop number, production line number, product type, spot inspection operation equipment serial number, spot inspection corresponding production equipment code, spot inspection equipment start-stop record, spot inspection equipment fault code, … }, and the specific field type can be adjusted according to the control requirement.
For example, the number of the cells to be processed,
{1 month 1 day 13 point 10 min to 1 month 1 day 18 point 15 min, 69771X car, stamping shop, production line No. two, production equipments No. 4, 7, 9 and 10, corresponding energy consumption of 4, 7, 9 and 10, no fault record, … }
…
{1 month 1 day 20 point 10 min to 1 month 2 day 04 point 30 min, 69771X vehicle, welding shop, production line number one, production equipment No. 14,19,22 and 47, corresponding energy consumption, no fault record, … }, 14,19,22 and 47
…, etc.;
the whole production period data can be determined to be related to the group according to the production time sequence.
Step 210: carrying out data cleaning on the energy consumption data association group;
it can be appreciated that data cleansing is a process of rechecking and checking data, aiming at deleting repeated information in the association group, correcting obvious errors, and maintaining data consistency so as to improve the quality of the data.
Step 220: splitting the historical energy consumption data association group into a management subset of a plurality of time scales under a plurality of use/application types, wherein the management subset comprises at least one of production day energy consumption, attendance non-production day energy consumption, weekend energy consumption and holiday energy consumption fields under each use/application type, and dividing the production day energy consumption into at least production period fixed consumption, change period change consumption and non-production period consumption subfields under each use/application type;
it should be noted that, the above-mentioned association group is divided into time subsets of multiple time scales under multiple uses/applications, and the division is to divide the time subsets into energy daily reports according to different production characteristics, and in general, the predictions of the energy consumption of the non-production energy, the energy consumption of the weekend and the energy consumption of the holiday are relatively accurate, and in the production days, since the energy consumption includes the variable consumption, when the production requirements and the external environment change rapidly, the energy consumption index of the workshop is difficult to predict directly, so that the division of the fixed and variable time periods under multiple use/application types is introduced, which is beneficial to fine energy prediction.
Step 230: and determining corresponding energy consumption standards by the subfields comprising the daily energy consumption fields in the management subset through energy consumption prediction, and determining corresponding energy consumption standards by the management subset of other daily energy consumption not produced through historical means.
It can be understood that the above-mentioned energy consumption prediction mode may be selected by any nonlinear regression prediction model in the prior art, and the implementation of the energy consumption prediction mode only needs to learn association group data under different time and different conditions as historical data to obtain energy consumption standards under specific time and specific conditions, and specific model implementation modes may be, for example, a BP neural network, a dynamic window sliding neural network, a convolutional neural network, an LSTM neural network, a radial base neural network, and the like, and details of the model in the prior art are not described again.
In addition, the usage of the non-production daily energy usage of the specific manufactured product is stable on the date, the corresponding energy consumption standard can be obtained by taking the average value of the historical data corresponding to the association group, and the average value calculation range is preferably the association group which is closest to a certain preset time period with the nearest predicted time.
Step S120, determining energy use prediction under the production plan based on the energy consumption standard and in combination with the production plan;
in a specific embodiment of the present invention, the production schedule includes at least a predetermined production quantity and production schedule.
In a specific embodiment of the present invention, the determining the energy forecast under the production plan based on the energy consumption standard in combination with the production plan includes determining the production schedule of one or more manufactured products to be produced according to the production plan, the production plan is divided into a combination of a minute plan, an hour plan, a day plan, a week plan and a month plan, and determining the energy consumption use forecast under the corresponding plan according to the energy consumption standard and the combination.
Preferably, when determining the energy consumption prediction, the condition that the primary qualification rate, the utilization rate, the repair rate and the like affect the energy consumption can be further considered, the energy consumption prediction is adjusted, the adjustment range can be set according to the historical experience of an actual production workshop or calculated by adopting any model, the invention is not limited to the condition, and the energy consumption prediction is implemented by adopting the prior art.
In the above embodiment, the production plan is divided into a plurality of scale combinations, and the production plan in a certain period is brought into the energy consumption standard, so that the energy prediction under a plurality of time scales after the output can be calculated.
The method breaks through the tradition of analyzing the energy consumption of a single unit in the traditional month, and can establish a set of energy refined prediction mode which is not influenced by the yield.
Step S130, obtaining a corresponding predicted energy consumption curve by using the energy use prediction, and obtaining a corresponding real-time energy consumption curve by using real-time energy consumption point detection data obtained by one or more remote distributed monitoring devices;
step S140, obtaining a difference group of pre-real differences of management subsets under a plurality of time scales under a plurality of different use/usage types of each monitoring device according to the expected energy consumption curve and the corresponding real-time energy consumption curve;
optionally, the pre-actual difference at least includes at least one of a curve maximum value, a curve minimum value, a curve point change rate, and a curve integral area, and it is understood that the index of the pre-actual difference reflects the energy consumption difference degree.
It is worth additionally stated that, by acquiring the energy consumption curve, the energy consumption difference can be visually seen in a visual manner, meanwhile, quantitative difference analysis can be performed through curve characteristics, and then, a difference group of pre-real differences under a plurality of different time scales is determined, wherein the difference group reflects the difference condition of each monitoring device under a preset time scale, for example:
{ (monitoring device 1, degree of energy consumption difference of first time scale under first use/usage type 1, degree of energy consumption difference of second time scale under second use/usage type 2, …, attribute field), (monitoring device 2,..degree of energy consumption difference 2, …, attribute field), … }.
Step S150, determining a corresponding management and control recommendation strategy based on the difference group;
in a specific embodiment of the present invention, based on a difference group of pre-implemented differences under different time scales under a plurality of usage/usage types of each monitoring device, pre-implemented fingerprint information vectors associated with each time scale are established, and analysis sentence segments in a preset analysis library are matched by using the fingerprint information vectors, and management and control recommendation strategies corresponding to a preset expert library are matched based on the analysis sentence segments.
It can be understood that the pre-compaction difference under different use/usage types can be reflected under different time scales, and the energy consumption standard of the pre-compaction difference under different production processes and production time periods is determined according to the foregoing, so that the predicted energy consumption under the corresponding time scales is determined, and therefore, when the predicted energy consumption deviates, the situation of energy waste or equipment abnormality can be generated, therefore, the corresponding information vector is obtained according to the difference group of the pre-compaction difference, and is matched with the analysis vector pre-stored in the pre-set analysis library on the management and control platform, and then the analysis sentence segment is matched from the analysis library, wherein the analysis vector is constructed for pre-offline simulation analysis or is extracted from historical data.
The above analysis vector is matched with the information vector, that is, the similarity between the two is measured, and the method can be implemented by any existing method in the prior art, which need not be further described herein.
The analysis library sentence segment is matched with a management and control recommended instruction corresponding to a preset expert library, and can be acquired through a database bar segment association mode in a management and control platform, so that further description is not needed.

nodes a, …, start-stop codes, PRE workshops, energy consumption is electric energy, the difference ratio is 10%, and the possible reasons are: the production equipment is replaced, and the single production time is prolonged;
node B, …, fault code, BIW shop, energy consumption is electric energy, the differential ratio is 1%, the possible reasons are: production equipment failure;

The energy consumption of the nodes C, … and PA workshops is electric energy, the difference proportion is-10%, and the possible reasons are as follows: the primary qualification rate is improved, the production speed is improved, and the management and control recommended strategy is as follows: reducing energy supply ration, adjusting and implementing part of weekend work, and reserving energy consumption adjustment allowance.
Step S160, implementing the control recommendation strategy to reduce the difference between the actual energy consumption curve and the target energy consumption curve;
the embodiment has smaller time scale analysis capability, can predict the energy consumption data in minute scale, so as to determine the reasons of the difference points of targets and actual energy consumption of each time scale under each use/application, discover the loss early, and automatically or semi-automatically regulate and adjust according to expert recommendation strategies, thereby ensuring the accuracy of the overall pre-actual differences of the whole month, quarter and year.
Step S170, after the management recommendation strategy is implemented, the energy consumption standard corresponding to the management subset is synchronously revised.
It can be appreciated that the above embodiment is a process of dynamically adjusting the iterative control, which combines an automatic management and control recommendation strategy, searches for energy loss points through a model to give an energy management and control/improvement suggestion, and can make the energy demand curve highly fit with the energy supply curve in the production process through continuous iterative management and control/improvement, so as to achieve the goal of energy conservation and carbon reduction.
