Description

Technical Field

[0001] This invention relates to the field of energy-saving technology in industrial parks, specifically a multi-dimensional data-driven smart park energy-saving system and method. Background Technology

[0002] With the deepening of smart park construction, IoT-based energy-saving systems have been widely used. These systems collect multi-dimensional data by deploying a large number of sensors to achieve automated energy-saving control of various devices. However, existing technologies generally suffer from insufficient rationality judgment when evaluating energy-saving effects.

[0003] Current methods rely heavily on simple comparisons of energy consumption data, failing to adequately consider various dynamic variables affecting energy consumption. These include changes in park occupancy rates, load fluctuations under different seasons and weather conditions, and the specific nature of production or operational activities, all of which significantly impact energy consumption benchmarks. Ignoring these key variables can easily lead to misjudgments of energy-saving effects. For example, attributing a natural decrease in energy consumption due to business contraction to energy-saving measures, or mistakenly rejecting effective energy-saving strategies due to increased energy consumption during peak operating periods. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-dimensional data-driven smart park energy-saving system and method to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-dimensional data-driven smart park energy-saving method, the energy-saving method comprising the following steps:

[0006] Step S100: Collect historical data of any energy-consuming equipment in the park, determine the energy consumption type of each energy-consuming equipment and classify the types; analyze the historical data of each energy-consuming equipment in any energy consumption type to obtain the comprehensive energy-saving efficiency of any energy consumption type.

[0007] Step S200: Compare the historical data of any energy-consuming device of the same energy consumption type to obtain the relevant factors affecting energy-saving efficiency of the same energy consumption type;

[0008] Step S300: Analyze the impact of various relevant factors on energy efficiency and generate a baseline energy-saving range for any energy consumption type;

[0009] Step S400: Compare the energy-saving status of any energy-consuming device with the benchmark energy-saving range of the corresponding energy consumption type to identify energy-saving deviations; based on the energy-saving deviations, identify relevant factors with energy-saving potential and formulate desired energy-saving strategies;

[0010] Step S500: Collect energy consumption data of any energy-consuming device in real time, analyze the real-time energy efficiency of any energy-consuming device, and extract abnormal related factors; based on the comparison with any desired energy-saving strategy, make a reasonable judgment on the actual energy saving situation.

[0011] Furthermore, step S100 includes the following steps:

[0012] Step S101: First, build an equipment monitoring system to store the equipment information of various energy-consuming devices in the park. At the same time, pre-divide several environmental dimensions and energy consumption indicators in the equipment monitoring system. Collect environmental data and energy consumption data of any energy-consuming device at every unit time point during operation through the equipment monitoring system. Match all environmental data with each environmental dimension to obtain the environmental data group of the energy-consuming device. At the same time, distribute each energy consumption data to each energy consumption indicator to obtain the various energy consumption indicators involved in the energy-consuming device. Generate the energy consumption indicator group of the energy-consuming device, and generate the corresponding energy consumption dataset for any energy consumption indicator in the energy consumption indicator group.

[0013] Environmental dimensions include indoor and outdoor temperature and humidity, lighting, foot traffic, equipment operating status and scheduling, production plans, etc., while energy consumption indicators include total power consumption, power per unit time, running time, load rate, energy efficiency ratio, average energy consumption, carbon emissions, etc.

[0014] Step S102: Randomly select two energy-consuming devices, extract the device information and energy consumption index groups of the two energy-consuming devices respectively, compare the two energy consumption index groups respectively, if the energy consumption indexes contained in the two energy consumption index groups are exactly the same, then use natural language processing technology to compare the similarity of the device information of the two energy-consuming devices, preset a similarity threshold, if the similarity of the two energy-consuming devices exceeds the similarity threshold, then set the two selected energy-consuming devices as devices of the same energy consumption type;

[0015] Step S103: Divide all energy-consuming devices in the park into several sets of energy-consuming devices of different types. Randomly select one energy-consuming device from one set of energy-consuming devices of a certain type, and select the a-th energy consumption index from the selected energy-consuming device. Obtain the energy consumption data E collected at the first time point of the a-th energy consumption index. s And the energy consumption data E collected at the last time point e The energy efficiency C of the a-th energy consumption index is calculated. a =(E e -E s ) / E s The average energy-saving efficiency of the selected energy-consuming equipment is obtained by averaging the energy-saving efficiency of each energy-consuming index among the selected energy-consuming equipment.

[0016] Step S104: Obtain the average energy-saving efficiency of each energy-consuming device in the selected energy-consuming type device set, and calculate the average value to obtain the comprehensive energy-saving efficiency of the selected energy-consuming type device set.

[0017] Furthermore, step S200 includes the following steps:

[0018] Step S201: Arbitrarily select a set of energy-consuming devices of a certain type. From this set, arbitrarily select one energy-consuming device. Obtain the average energy-saving efficiency of the selected device during its operation over a specified time interval. Define the average energy-saving efficiency at the i-th time point within the selected time interval as C. i The average energy-saving efficiency at the j-th time point is C. j A preset efficiency change threshold ΔC is defined. th If |C i -C j |≥ΔC th Then, the i-th time point and the j-th time point are set as the first target time point group. If |C i -C j |<ΔC th Then, the i-th time point and the j-th time point are set as the second target time point group; the first target time point group indicates that the energy efficiency change between the two time points is relatively large, and the second target time point group indicates that the energy efficiency change between the two time points is relatively small;

[0019] Step S202: Acquire the environmental data sets for the two time points in the target time point group respectively. Randomly select one environmental dimension and extract the environmental data for that dimension from the two environmental data sets. Let the environmental data for the i-th time point be D. i The environmental data at time point j is D. j A preset data change threshold ΔD is set for the selected environmental dimension. th If |D i -D j |≥ΔD th Then the environmental dimension will be set as the first target dimension. If |D i -D j |<ΔD th If the environmental dimension is selected, it will be set as the second target dimension; the first target dimension indicates that the data variation of the environmental dimension is too large, and the second target dimension indicates that the data variation of the environmental dimension is too small.

[0020] Step S203: Calculate the average energy efficiency difference between any two time points to generate several first target time point groups and several second target time point groups. Divide each environmental dimension in any target time point group into a first target dimension set and a second target dimension set. Perform a union operation on several first target dimension sets in several first target time point groups to obtain a relevant dimension set. Perform a union operation on several first target dimension sets in several second target time point groups to obtain an irrelevant dimension set. Simultaneously, perform a union operation on several second target dimension sets in several first target time point groups to obtain another irrelevant dimension set. Perform a union operation on the two irrelevant dimension sets to obtain a comprehensive irrelevant dimension set. If a target dimension in the relevant dimension set is the same as a target dimension in the comprehensive irrelevant dimension set, remove the target dimension from the relevant dimension set to obtain a corrected relevant dimension set.

[0021] To determine which dimensions affect energy efficiency, we first identify which dimensions have the largest changes and also the largest changes in energy efficiency. These are the most direct influencing dimensions. Meanwhile, dimensions with large changes but small changes in energy efficiency are defined as irrelevant dimensions. Next, we summarize the influencing dimensions by taking the union of different devices and unify the influencing dimensions by comparing similar devices. This will give us accurate relevant factors.

[0022] Step S204: Obtain the relevant dimension set and the comprehensive irrelevant dimension set for each energy-consuming device in the selected energy-consuming device set during operation. Perform an intersection operation on all relevant dimension sets to obtain a common dimension set and a difference dimension set. Randomly select a difference dimension from the difference dimension set. If the selected difference dimension does not have the same dimension in any of the comprehensive irrelevant dimension sets, add the selected difference dimension to the common dimension set to obtain a corrected common dimension set. Set each environmental dimension in the corrected common dimension set as a relevant factor affecting the energy-saving efficiency of the selected energy-consuming device set.

[0023] Furthermore, step S300 includes the following steps:

[0024] Step S301: Arbitrarily select one energy-consuming device from the set of energy-consuming devices of a certain type, extract the k-th environmental dimension from the selected energy-consuming device, and obtain the environmental data (D) of the k-th environmental dimension at the first time point during the operation of the selected energy-consuming device. s ) k and environmental data at the last time point (D e ) k The change magnitude Δf of the kth environmental dimension is calculated. k=[(D e ) k -(D s ) k ] / (D s ) k ;

[0025] Step S302: Set the overall energy-saving efficiency of the selected energy-consuming equipment to C. com According to the formula:

[0026] ;

[0027] Where p is a positive integer and p∈[1,u], u is the total number of environment dimensions, and Δf p Let p be the magnitude of change in the p-th environmental dimension; calculate the degree of influence y of the k-th environmental dimension. k ;

[0028] Step S303: Extract several relevant factors from the set of energy-consuming devices of the selected energy-consuming type, and obtain the influence degree of each relevant factor. The influence degree of the q-th relevant factor is set as y. ’ q And the change range is Δf ’ q According to the formula:

[0029] ;

[0030] Where v represents the number of relevant factors for selecting energy-consuming equipment; the baseline energy-saving efficiency C of the selected energy-consuming equipment is calculated. ’ com The baseline energy-saving efficiency of each energy-consuming device in the selected energy-consuming device set is obtained, and the baseline energy-saving range of the selected energy-consuming device set is generated. The baseline energy-saving range is used to determine whether the energy-consuming device meets the most basic energy-saving efficiency, and at the same time, it can provide a basis for comparison to determine whether there is further energy-saving space.

[0031] Furthermore, step S400 includes the following steps:

[0032] Step S401: Randomly select a set of energy-consuming devices of a certain type to obtain the baseline energy-saving range of the selected set of energy-consuming devices. Randomly select one energy-consuming device from the selected set of energy-consuming devices to obtain the comprehensive energy-saving efficiency C of the selected energy-consuming device. com The maximum energy efficiency within the benchmark energy-saving range is set as (C). com ) max The energy-saving deviation value ΔC of the selected energy-consuming equipment is obtained. com =(C com ) max -C com ;

[0033] Step S402: Obtain the influence degree of each relevant factor in the selected energy-consuming equipment, and set the influence degree of the q-th relevant factor as y. ’ q According to the formula:

[0034] ;

[0035] Where r is a positive integer and r∈[1,v], v is the number of relevant factors selected for energy-consuming devices, and y ’ r The influence degree of the r-th related factor is given; the expected energy saving deviation (Δf) of the q-th related factor is calculated. ex ) q ;Preset the expected deviation range of the relevant factors, if the expected energy saving deviation (Δf) of the q-th relevant factor ex ) q If the value is within the expected deviation range, then the qth relevant factor is set as the energy-saving potential factor;

[0036] Step S403: Summarize each energy-saving potential factor and its corresponding expected energy-saving deviation to generate a corresponding expected energy-saving strategy.

[0037] Furthermore, step S500 includes the following steps:

[0038] Step S501: Randomly select an energy-consuming device, collect the environmental data set and energy consumption data set of the selected energy-consuming device in real time, and obtain the real-time energy-saving efficiency of the selected energy-consuming device; extract several relevant factors of the set of energy-consuming devices of the selected energy-consuming device type, obtain the influence degree of each relevant factor, and obtain the expected change range of each relevant factor.

[0039] Step S502: Obtain the real-time change range of each relevant factor. If the real-time change range of a certain relevant factor is less than the expected change range, then set the certain relevant factor as an abnormal relevant factor to obtain several abnormal relevant factors for selecting energy consumption equipment.

[0040] Step S503: Randomly select an abnormal correlation factor and obtain the expected energy saving deviation of the selected abnormal factor; arbitrarily select an expected energy saving strategy. If all the abnormal correlation factors of the selected energy-consuming equipment and the corresponding expected energy saving deviations are within the selected expected energy saving strategy, then the expected energy saving strategy is invoked for energy saving adjustment. If they are not within the selected expected energy saving strategy, then an abnormal reminder is sent to the real-time energy saving status.

[0041] To better implement the above methods, a smart park energy-saving system is also proposed. The energy-saving system includes an energy consumption data analysis module, a relevant factor extraction module, a benchmark range generation module, an energy-saving potential realization module, and a reasonable energy-saving judgment module.

[0060] Example: Figures 1 to 2 As shown, this invention provides a multi-dimensional data-driven smart park energy-saving method, which includes the following steps:

[0061] Step S100: Collect historical data of any energy-consuming equipment in the park, determine the energy consumption type of each energy-consuming equipment and classify the types; analyze the historical data of each energy-consuming equipment in any energy consumption type to obtain the comprehensive energy-saving efficiency of any energy consumption type.

[0062] Step S100 includes the following steps:

[0063] Step S101: First, build an equipment monitoring system to store the equipment information of various energy-consuming devices in the park. At the same time, pre-divide several environmental dimensions and energy consumption indicators in the equipment monitoring system. Collect environmental data and energy consumption data of any energy-consuming device at every unit time point during operation through the equipment monitoring system. Match all environmental data with each environmental dimension to obtain the environmental data group of the energy-consuming device. At the same time, distribute each energy consumption data to each energy consumption indicator to obtain the various energy consumption indicators involved in the energy-consuming device. Generate the energy consumption indicator group of the energy-consuming device, and generate the corresponding energy consumption dataset for any energy consumption indicator in the energy consumption indicator group.

[0064] Step S102: Randomly select two energy-consuming devices, extract the device information and energy consumption index groups of the two energy-consuming devices respectively, compare the two energy consumption index groups respectively, if the energy consumption indexes contained in the two energy consumption index groups are exactly the same, then use natural language processing technology to compare the similarity of the device information of the two energy-consuming devices, preset a similarity threshold, if the similarity of the two energy-consuming devices exceeds the similarity threshold, then set the two selected energy-consuming devices as devices of the same energy consumption type;

[0065] Step S103: Divide all energy-consuming devices in the park into several sets of energy-consuming devices of different types. Randomly select one energy-consuming device from one set of energy-consuming devices of a certain type, and select the a-th energy consumption index from the selected energy-consuming device. Obtain the energy consumption data E collected at the first time point of the a-th energy consumption index. s And the energy consumption data E collected at the last time point e The energy efficiency C of the a-th energy consumption index is calculated. a =(E e -E s ) / E s The average energy-saving efficiency of the selected energy-consuming equipment is obtained by averaging the energy-saving efficiency of each energy-consuming index among the selected energy-consuming equipment.

[0066] Step S104: Obtain the average energy-saving efficiency of each energy-consuming device in the selected energy-consuming type device set, and calculate the average value to obtain the comprehensive energy-saving efficiency of the selected energy-consuming type device set.

[0067] Step S200: Compare the historical data of any energy-consuming device of the same energy consumption type to obtain the relevant factors affecting energy-saving efficiency of the same energy consumption type;

[0068] Step S200 includes the following steps:

[0069] Step S201: Arbitrarily select a set of energy-consuming devices of a certain type. From this set, arbitrarily select one energy-consuming device. Obtain the average energy-saving efficiency of the selected device during its operation over a specified time interval. Define the average energy-saving efficiency at the i-th time point within the selected time interval as C. i The average energy-saving efficiency at the j-th time point is C. j A preset efficiency change threshold ΔC is defined. th If |C i -C j |≥ΔC th Then, the i-th time point and the j-th time point are set as the first target time point group. If |C i -C j |<ΔC th Then the i-th time point and the j-th time point are set as the second target time point group;

[0070] Step S202: Acquire the environmental data sets for the two time points in the target time point group respectively. Randomly select one environmental dimension and extract the environmental data for that dimension from the two environmental data sets. Let the environmental data for the i-th time point be D. i The environmental data at time point j is D. j A preset data change threshold ΔD is set for the selected environmental dimension. th If |D i -D j |≥ΔD th Then the environmental dimension will be set as the first target dimension. If |D i -D j |<ΔD th Then the selected environment dimension will be set as the second target dimension;

[0071] Step S203: Calculate the average energy efficiency difference between any two time points to generate several first target time point groups and several second target time point groups. Divide each environmental dimension in any target time point group into a first target dimension set and a second target dimension set. Perform a union operation on several first target dimension sets in several first target time point groups to obtain a relevant dimension set. Perform a union operation on several first target dimension sets in several second target time point groups to obtain an irrelevant dimension set. Simultaneously, perform a union operation on several second target dimension sets in several first target time point groups to obtain another irrelevant dimension set.

For the first target time point group, the outdoor temperature dimension is extracted from the environmental data group, and the temperature D at time point i is... i =28℃, temperature D at time point j j =32℃, preset data change threshold ΔD th=3℃. Since |28-32|=4℃≥3℃, "outdoor temperature" is set as the first target dimension. Repeat the above operation to generate multiple first target time point groups and second target time point groups. By taking the union and intersection operations, the relevant dimension set including outdoor temperature and operating mode is obtained, and the irrelevant dimension set including humidity is integrated. Take the intersection of the relevant dimension sets of all devices in the air conditioning equipment set to obtain the common dimension set as outdoor temperature, and add the other differential dimensions as operating mode to the common set.
