Description

Technology Field

[0001] The present invention relates to a 3D visualization system using digital twin technology and an energy saving method. Specifically, it relates to a system that visualizes a unit in 3D using digital twin technology and a method for saving energy through predictive model control. Background Technology

[0003] A digital twin is a virtual model that describes dynamic properties while maintaining identity and consistency with a real-world physical system (e.g., transportation systems, production systems, etc.) <e.g., discrete event models, physics-based models, statistical models, machine learning models, etc.>.

[0004] By performing simulations on a digital twin developed using the operating procedures / rules of a real-world system of interest, real-time operational data, aggregated data of the same group, operational history, maintenance history, Failure Mode and Effects Analysis (FMEA), Finite Element Analysis (FEA) models, CAD models, etc., according to scenarios formed by combinations of input variables, it is possible to analyze the behavior of the actual system, diagnose failures, or achieve operation-related prediction and optimization.

[0005] Meanwhile, modeling simulation technology, which enables simulation in a virtual world based on scenarios formed from input variable values ​​for system analysis through various virtual experiments that are difficult or impossible to perform in the real world due to reasons such as excessive costs for analysis when using actual systems, safety risks during execution, and the inability to apply them to objects that do not exist in reality but only exist as concepts or plans, has long been widely used as a scientific analysis method in almost all domains.

[0006] Bioenergy, which is recently evaluated as one of the alternative energy sources to address issues such as the depletion of fossil fuels, safety concerns regarding nuclear power generation, and the high costs and low efficiency of using other energy sources, can be used in various ways depending on its purpose and form, including biogas, bioethanol, biodiesel, methanol, and hydrogen, as well as for heating, automotive fuel, and power generation fuel.

[0007] Biomass refers to organisms, such as plants and microorganisms, that can be used as energy sources for bioenergy and are produced during ecosystem cycles.

[0008] Representative biomass includes woody materials such as grains, waste wood, plant stems, and tree bark, as well as seaweed, animal manure, food waste, and organic wastewater. These materials are used to extract bioenergy through pyrolysis or fermentation processes, or converted into products such as compost, animal feed, and various plastics.

[0009] Biomass fuels generally exhibit characteristics such as heterogeneity in composition and content, and water reabsorption due to low density and calorific value, high moisture content, difficulties in crushing and grinding, and various types and growth environments. As a result, it is difficult to produce synthesis gas with a stable composition, so thermal pretreatment such as torrefaction must be performed beforehand.

[0010] In conventional biomass gasification, a large amount of energy is required for the moisture evaporation, heating of combustible matter, evaporation of volatile matter, and heating of ash during the moisture evaporation and devolatilization processes when biomass is input. In particular, since the energy required for moisture evaporation is the highest, moisture content has an absolute impact, so moisture content control must be performed through pretreatment.

[0011] Furthermore, while quality can be improved through the aforementioned preprocessing, conventionally, operations have been performed based on the operator's experience, leading to problems such as inconsistent quality or the production of low-quality products. Additionally, the absence of a system utilizing digital twins has resulted in issues such as energy waste.

[0068] In addition, the verification means may include means for monitoring operation and status values ​​in real time and quantifying and storing the degree of deviation when it deviates from a set similar level.

[0069] In addition, any one or more of the above database and DT computing engine can collect additional data using an external platform.

[0070] In addition, the above external platform may be one or more of Kafka and Zookeeper.

[0071] In addition, the 3D visualization device can further utilize normalized vision data.

[0072] In addition, the above vision data may be data that acquires an image of the used ash.

[0073] The above vision data consists of three types: one for measuring flames, another for measuring chars for feedback control, and the last one for measuring ash. So, after first creating a normalization that adjusts data with a resolution of 255 or 1024 to 100, the normalized RGB values ​​are combined to form a single time series data, and this time series data can enable energy-saving operation through feedback via linear prediction.

[0074] The above normalized vision data may be data including RGB, and the RGB may include all data using the three primary colors, Red, Green, and Blue.

[0075] In addition, the normalized vision data may additionally include means for normalizing data using the three primary colors, or may utilize pre-normalized data.

[0077] In addition, the moisture content of raw materials or products can be measured and predicted through the above-mentioned normalized vision data.

[0078] In addition, a high moisture content is disadvantageous in terms of density because it retains a large amount of water, whereas the less moisture there is, the higher the density, making it suitable for use as a good torrefied fuel.

[0079] In addition, for this process, the speed of the conveyor belt motor that feeds fuel is controlled, the burner of the combustion furnace is controlled through dual PID control, the speed of the screw (feeder) inside the combustion furnace is controlled, and the condition of the ash is measured through a vision system and the operating value after one minute is predicted to save energy and enable optimal control operation.

[0080] Furthermore, torrefied materials that have undergone the torrefaction process have lower moisture content and an O / C (oxygen / carbon) ratio, and can possess high energy density and calorific value suitable for fuel. (Moisture decreases during torrefaction (moisture content decreases)) More precisely, the oxygen and hydrogen components decrease and change into carbon properties. A vision-based prediction engine can be used to control this.

[0081] In addition, the normalized vision data can be used in one or more of the database, AI modeling engine, intelligent central control system, 3D visualization engine, and DT computation engine. Additionally, it can also be used at the time of raw material input.

[0084] In addition, the above steps 4-1, 4-2, 4-3, and 4-4 may proceed in order or independently regardless of order.

[0085] In addition, the above operation step can be performed regardless of the order of progress of steps 1 through 5.

[0086] In addition, a data statistical prediction model may be used in the third step mentioned above.

[0087] In addition, the above data statistical prediction model may include a step of clustering the received signals and having the AI ​​model learn on a unit basis.

[0088] In addition, the data statistical prediction model may include a step in which the AI ​​model compares the learned unit with the current state and waveform on a unit-by-unit basis and calculates the degree of similarity.

[0089] In addition, the above data statistical prediction model may include a verification step that verifies through a verification method.

[0090] In addition, the verification step may include a step of monitoring the waveform in real time and saving an abnormal signal simultaneously with an alarm if it deviates from a set similar level.

[0091] In addition, the verification step may include a step of monitoring operation and status values ​​in real time and quantifying and storing the degree of deviation when it deviates from a set similar level.

[0092] In addition, the above system may further include a step of selecting an optimal algorithm based on the sequence for selecting an optimal algorithm.

[0093] In addition, the purpose of the optimal algorithm in the present invention is to produce a carbonized material with a high calorific value and high quality.

[0094] Furthermore, the optimization module of the aforementioned optimization algorithm performs operational optimization based on quality prediction results obtained through simulation production and carbonization. The optimization algorithm is based on the Tabu Search algorithm. The Tabu Search algorithm is a metaheuristic algorithm designed to solve a given optimization problem regardless of its form; it is an algorithm that avoids local optima and searches for an optimal solution by storing information (Tabu) about local optima to solve problems that converge to a local optimum.

[0095] In addition, the above optimal algorithm can select the optimal production location based on constraints and considerations when the product moves to the supplier, secondary manufacturer, and primary manufacturer.
