Description

Technical Field

[0001] This invention relates to the fields of environmental engineering and resource recycling technology, and in particular to a centralized system and method for the resource utilization of solid waste from jade processing. Background Technology

[0002] Jade carving instruction often generates a large amount of fine dust, which not only pollutes the air and affects the health of the workers, but is also often simply discarded as waste, resulting in resource waste. With simultaneous operations in the classroom, ordinary dust removal equipment is insufficient to effectively reduce the dust content in the air. Technically, current technologies focus on dust removal effectiveness, but do not provide detailed explanations on how to process and utilize the collected jade dust.

[0003] The negative pressure dust removal system mainly consists of four parts: a suction pipe, an air pump, a dust delivery pipe, and a dust collection box. Its principle is that after the air pump starts, it generates suction, drawing dust from the suction pipe and discharging it to the dust collection box through the dust delivery pipe. The dust collection box needs to be cleaned when it has collected a certain amount of dust. The solid waste collection system uses additional transmission, motor, or exhaust fan devices to collect and classify solid waste, centralizing it into usable resources.

[0004] Currently, there are some patented technologies for the centralized treatment and utilization of jade carving dust and waste, but the utilization of dust as waste has not yet been realized.

[0005] Chinese Patent Publication No. CN203901544U, entitled "A Dust Removal System for a Workbench in a Stone Processing Production Workshop," discloses a dust removal system for a workbench in a stone processing production workshop. The system includes a workbench, with a dust collection device on one side. This dust collection device contains a dust collection chamber. One end of a duct is connected to the dust collection chamber, and the other end has a suction port near the workbench. A fan is installed inside the duct. Several dust collection bags are longitudinally distributed within the dust collection chamber, with several air outlets corresponding to the top of each bag. A dust collection hopper is located at the bottom of each dust collection bag. The system fully considers the characteristics of stone processing at the workbench and, based on the dust generation curve during worker operation, ensures that dust is effectively removed at the lower suction port immediately after generation, bypassing the worker's respiratory tract. This ensures the health of the worker's respiratory system and effectively suppresses pollution caused by dust dispersion.

The dust collection device is composed of a dust collection nozzle, a dust collection motor and a dust collection device. The dust collection nozzle is fixedly connected with the machine head. A dust collector hose is arranged between the dust collection nozzle and the dust collection device. The dust collection motor is arranged in the dust collection device. The carving machine device and the dust collection device are respectively connected with the control console. Dust is sucked into the dust collection device through the dust collection nozzle, effectively preventing dust from scattering and maintaining the production environment, and protecting the health of the operators.

[0007] The patent document with the Chinese patent publication number CN206012177U and the name of a jade carving device dust removal system discloses a jade carving device dust removal system, which comprises an air pump, a dust suction pipe and a dust delivery pipe.

By arranging the body, the placing rack, the collecting cavity, the air extractors, the absorption rack, and the powder feeding rack, the air extractors suck in more jade slag and powder through the powder feeding rack, and the slag powder enters the collecting cavity through the absorption rack, solving the problem that the powder absorption efficiency of existing equipment is not high, some equipment cannot collect jade slag, and jade slag is easy to block the equipment, causing damage to the equipment and affecting the normal use of the equipment.

[0010] The inventor found that the prior art has at least the following disadvantages in the process of implementing the present application: the existing dust removal system related to jade carving only describes how to add a dust removal system beside the jade carving table, but the scenarios it can deal with are relatively limited, and the range it can control is limited to the vicinity of the operation table. There is no explicit description of how to achieve centralized dust removal in a larger space. The existing solid waste recycling system does not explain how to specifically handle the waste of jade carving. The existing jade carving slag treatment and collection device is similar to a general dust removal device, and there is no step of reusing dust. SUMMARY

[0062] Exemplary embodiments of the present application are described herein below with reference to the accompanying drawings, in which various details are set forth by way of exemplification. Thus, it will be apparent that changes and modifications can be made to the embodiments described herein, without departing from the spirit and scope of the application. Also, for clarity and conciseness, the description herein will omit the description of well-known functions and structures.

[0063] One of the purposes of the embodiments of the present application is to solve the collection and resource utilization of jade carving dust in a centralized production environment. On the basis of improving the existing negative pressure dust removal device, the embodiments of the present application add dust sorting, collecting, precipitating and transporting modules, and use the screened waste as a production raw material for ceramic process, realizing the recycling and sustainable development of jade processing waste.

[0064] As shown in Figure 1 The embodiments of the present application provide a centralized jade processing solid waste resource utilization system, which comprises a dust suction module, a negative pressure module, a dust collecting module, a gate, a screening module, a recycling module and a precipitation module. The dust suction module is used to suck the jade dust generated by the jade processing work module through a pipeline. The negative pressure module is used to generate suction force to transport the jade dust to the dust collecting module. The dust collecting module is used to temporarily store the jade dust. The gate is used as a switch to control the jade dust from the dust collecting module to enter the screening module. The screening module is used to screen and classify the jade dust to obtain the jade dust corresponding to the first particle size range, the second particle size range and the third particle size range. The recycling module is used to recycle the jade dust in the first particle size range for first resource processing, and recycle the jade dust in the second particle size range for second resource processing. The precipitation module is used to perform third resource processing on the jade dust in the third particle size range. The first particle size range is larger than the second particle size range, and the second particle size range is larger than the third particle size range.

[0065] Specifically, the work module is a jade carving operation position. The dust suction module has a pipeline for sucking dust. The negative pressure module has an air compressor for generating suction force. The dust collecting module provides a position for temporarily storing dust. The gate is a switch to control the dust from the dust collecting module to enter the screening module. The screening module is a space for screening and classifying the jade dust. The recycling module is used to recycle the coarse and medium particle size jade dust and resource it. The precipitation module is used to resource the finest jade dust.

[0066] The gate is designed for automatic control and can open in three situations. The first situation is when the engraving work is finished and the negative pressure module is shut down; in this case, the gate automatically opens, allowing dust to settle into the screening module. The second situation is when the dust collection module has excessive dust. A dust concentration sensor is installed in the dust collection module; when the dust volume reaches a threshold (e.g., 80% of the module's capacity), the negative pressure module automatically shuts down, and the gate automatically opens, allowing dust to settle into the screening module. The third situation is when the negative pressure module has been running for an extended period and there is a risk of overheating of internal components. The system automatically monitors the temperature of the negative pressure module components and issues a stop command; in this case, the negative pressure module automatically shuts down, and the gate automatically opens, allowing dust to settle into the screening module.

[0067] In some embodiments, the negative pressure module can be manually activated, turning on immediately when jade carving is required, without waiting for the dust concentration to rise.

[0068] In some embodiments, a dust concentration sensor is installed at the branch pipe. When the dust concentration is below a threshold, the corresponding branch pipe is automatically shut off to avoid collecting too many other suspended particles in the air, which would affect the collection of jade dust.

[0069] In some embodiments, a filter screen is provided between the negative pressure module and the dust collection module to prevent dust from being sucked into the negative pressure module.

[0070] The working principle of the centralized jade processing solid waste resource utilization system is explained as follows:

[0071] The working module mainly includes an electric jade cutting machine and electric carving pen, a water tank, and a dust-suppressing water pipe. This is the work surface where the operator carves the jade, generating a large amount of jade dust. When the operator operates the cutting machine and electric carving pen on the jade raw material, the high-speed cutting blade causes the generated dust to splash. The water flow in the dust-suppressing water pipe can suppress some of the splashed dust, but it cannot cause all the dust to settle. Dust carried by the water flow flows into the water tank for sedimentation, while dust not carried by the water flow is extracted by the negative pressure module.

[0072] The negative pressure module generates suction force and collects dust from each workbench in the work module into the dust collection module through the dust collection module. The interface between the negative pressure module and the dust collection module is a spiral-shaped fan blade that can rotate 360 degrees to generate negative pressure. The fan blade is separated from the dust collection module by a filter screen to prevent dust from being absorbed into the negative pressure module. The dust collection module is connected to the dust collection module through a main pipeline, and the other end of the main pipeline leads to the work module and branches into multiple secondary pipelines. The end face diameter of the secondary pipeline is smaller than the end face diameter of the main pipeline. The secondary pipeline further branches into multiple tertiary pipelines, which directly correspond to the work module and are suspended directly above the corresponding work module. The end face diameter of the tertiary pipeline is consistent with the end face diameter of the secondary pipeline. The dust generated by each work module is first collected into the secondary pipeline through the tertiary pipeline, and the dust in each secondary pipeline is then collected into the main pipeline and finally into the dust collection module.

[0073] After the dust collection is completed, the gate below the dust collection module is opened, allowing the dust to pass through the screening module under the action of gravity. Dust of different particle sizes is retained in different filter screen layers and enters the recycling module or the sedimentation module. After screening, dust of different particle sizes in different layers can be reused as stone powder material. In one example, the filter screen layer has two layers, 500 mesh and 1000 mesh. The coarse dust that does not pass through the 500 mesh filter screen slides into the recycling module 1 along the inclined filter screen slope and becomes coarse sand, which can be used as polishing and polishing material, building filling material, water permeable brick synthesis raw material, soil conditioner, heavy metal adsorbent, etc. The medium dust that passes through the 500 mesh filter screen and does not pass through the 1000 mesh filter screen slides into the recycling module 2 along the inclined filter screen slope and becomes fine sand for making pottery. The fine dust that passes through the 1000 mesh filter screen enters the lowermost sedimentation module, combines with water therein and undergoes a chemical reaction to form mud dust, which can be used as porcelain clay for ceramic process, realizing the resource utilization of jade dust.

[0074] The action relationship of the centralized jade processing solid waste resource utilization system is explained as follows:

[0075] The working module and the dust collection module are connected through a funnel-shaped nozzle (the purpose of the funnel shape is to ensure that as much dust as possible is collected by the dust collection module), ensuring that the dust is not taken directly by the dust collection module through the operator. The negative pressure module is directly connected to the dust collection module, and the negative pressure module is arranged above the dust collection module. The dust collection module is directly connected to the other end of the dust collection module. When the dust collection work is carried out, the gate below the dust collection module is closed, so that the dust collection module and the dust collection module form a closed pipeline system. The dust collection module is connected to the screening module through the gate, and the screening module is provided with multiple filtering screens with different mesh sizes. The lower part of the screening module is connected to one or more recycling modules and sedimentation modules. The larger size of the jade dust is screened by the filter screen and enters the corresponding recycling module, and the finest dust enters the sedimentation module. The sedimentation module contains water to facilitate the recycling of the finest jade dust.

[0076] When the negative pressure module and the dust collection module are opened, the temperature of the components of the negative pressure module, the dust concentration in the dust collection module, and whether the working module is running are controlled. The gate below the dust collection module is opened only after the negative pressure module enters the dust removal state. In three cases, the negative pressure module is closed, and the gate below the dust collection module is opened. The first case is that the carving work is completed, the negative pressure module is closed, and at this time the gate is automatically opened to allow the dust to settle in the screening module. The second case is that the amount of dust in the dust collection module is too much. A dust concentration sensor is arranged in the dust collection module. When the dust concentration in the dust collection module reaches a threshold value (80% of the capacity of the dust collection module), the negative pressure module is automatically closed, and the gate is automatically opened to allow the dust to settle in the screening module. The third case is that when the negative pressure module runs for too long and the internal components are at risk of overheating, the system automatically monitors the component temperature of the negative pressure module and issues a stop working instruction. At this time, the negative pressure module is automatically closed, and the gate is automatically opened to allow the dust to settle in the screening module.

[0077] In order to clean the residual dust in the secondary pipeline, the tertiary pipeline, the dust collection module and the negative pressure module, after the dust collection module gate is opened and emptied, the gate is closed, and the negative pressure module is separately opened when the working module stops working, and the dust in the pipeline of the dust collection module is concentrated in the dust collection module. A cleaning system and a dust sensor are separately arranged in the negative pressure module. When the dust in the negative pressure module exceeds the threshold value, the cleaning system in the negative pressure module will be opened to clean the inner wall, fan, filter screen and other components of the negative pressure module. The water flow of the flushing flows through the dust collection module, which will clean the residual dust in the dust collection system. The water flow carrying the residual dust is received by the filter screen in the screening module, the larger particles continue to pass through the filter screen and are separated into two recycling modules, and the finest dust is collected in the sedimentation module with the water flow to form the porcelain mud that can be reused.

[0078] As shown in Figure 2 The control algorithm of the gate below the dust collection module includes the following steps:

[0079] S10: Perform system state modeling to obtain a system current state, the system current state including a state of a working module, a dust concentration of a dust collection module, a temperature of a negative pressure module, and a continuous running time length of the negative pressure module, to obtain a system state vector;

[0080] S20: Based on the system state vector, construct a multi-objective optimization model, the optimization objectives of the multi-objective optimization model including maximum dust treatment efficiency, minimum equipment wear, and minimum energy consumption, and a comprehensive optimization objective function is constructed by using a weighted summation method;

[0081] S30: Based on the system state vector, calculate a dust concentration error, a temperature change rate, and a running time integral value, and make a decision according to a preset control rule to obtain a control decision result, the control rule including: when the jade dust concentration is high or the temperature exceeds a set threshold value, or the working module stops, performing a gate opening operation; when the jade dust concentration is medium and the temperature change rate exceeds a set threshold value, performing a gate opening and predictive dust removal operation; when the continuous running time length exceeds a set safety time length, performing a forced cooling operation;

[0082] S40: According to the comprehensive optimization objective function and the control decision result, an online optimization is performed on control parameters including a dust concentration threshold value, a temperature threshold value, and a minimum running interval by using a multi-objective optimization algorithm, and an optimal parameter combination meeting safety constraints and equipment constraints is output.

[0083] Further, the control decision in the step S30 is based on a fuzzy membership function calculation result for reasoning, and the membership function includes a trapezoidal or triangular function representing low, medium, and high dust concentrations.

[0084] Further, the method further includes a step S50 for performing predictive maintenance. S50: Based on the system state historical data obtained in the step S10, a time series prediction network is used to predict future states, and the remaining time required to reach the dust concentration threshold value and the temperature threshold value is output; when any predicted remaining time is less than a safety margin threshold value, a predictive dust removal operation is triggered, and the prediction result is used as a control input for the step S30.

[0085] Further, the method further includes a step S60 for implementing a safety protection mechanism. S60: A hardware watchdog timer is used to monitor the system running state, and when it is detected that the gate opening time exceeds a set upper limit, or the temperature exceeds a maximum allowable threshold value, or the dust concentration exceeds an emergency threshold value, a shutdown or emergency dust removal measure is immediately triggered.

[0086] Further, the method further comprises a step S70 for realizing parameter self-tuning. S70: based on the system state information in step S10, a reinforcement learning algorithm is used to dynamically adjust the weight coefficients in the comprehensive optimization objective function in step S20, so as to improve the overall system operation performance, the adjustment action is selected according to the reward and punishment mechanism, and the output result is fed back to update the optimization strategy.

[0087] Specifically, the control algorithm of the lower gate of the dust collection module is described in detail as follows:

[0088] (1) System state modeling

[0089] The system state vector S = [W, C, T, t] is defined. Wherein, W ∈ {0, 1} represents the working module state, 0 represents stop, and 1 represents running; C ∈ [0, 100%] represents the dust concentration of the dust collection module; T ∈ [℃] represents the temperature of the negative pressure module; t ∈ [s] represents the continuous running time of the negative pressure module.

[0090] (2) Multi-objective optimization function design, three optimization objectives are established

[0091] Optimization objective 1 is to maximize the dust treatment efficiency, f1 = Σ(ΔC_i) / t_cycle; Wherein, ΔC_i is the change amount of the dust concentration of the dust collection module in the i th sampling period (unit is %), t_cycle is the time length of a complete control cycle (unit is second). This optimization objective indicates the cumulative change amount of the dust concentration per unit time, which represents the system processing efficiency.

[0092] Optimization objective 2 is to minimize the equipment wear and tear, f2 = α1ΣΔT + α2N_cycles; Wherein, ΣΔT is the cumulative value of the temperature fluctuation during the operation of the negative pressure module (unit is ℃), N_cycles is the cumulative number of gate opening and closing actions (unit is times), α1 is the weight coefficient of the influence of temperature fluctuation on equipment wear and tear (dimensionless), α2 is the weight coefficient of the influence of mechanical action times on equipment wear and tear (dimensionless). This optimization objective quantifies the comprehensive influence of temperature change and mechanical wear and tear on equipment life.

[0093] Optimization objective 3 is to minimize the energy consumption, f3 = β1P_avg + β2N_switch. Wherein, P_avg is the average running power of the negative pressure module (unit is kW), N_switch is the number of system mode switching (unit is times), β1 is the steady-state energy consumption weight coefficient (dimensionless), and β2 is the transient energy consumption weight coefficient (dimensionless). This optimization objective represents the total energy consumption of steady-state operation and dynamic adjustment.

[0094] The weighted sum method is used to construct the comprehensive objective function (the weight coefficients need to be calibrated according to the device parameter experiment) as follows: F = w1f1 + w2f2 + w3f3.

[0095] (3) Core control algorithm flow

[0096] Improved fuzzy-PID control structure is adopted:

[0097] 1) Input layer

[0098] Dust concentration error is e_C = C_set - C_actual, temperature change rate is dT / dt, and working time integral is ∫t.

[0099] 2) Fuzzy layer

[0100] The membership function is defined as follows:

[0101] μ_low(C) = trapezoid(0, 0, 30%, 50%); wherein, it represents the fuzzy set of "low dust concentration", and the function type is trapezoidal membership function. The left bottom edge has a starting point and an ending point of 0% and 0%, respectively, and the membership degree is constant at 1 when the concentration is less than or equal to 30%. The starting point of the right bottom edge is 30%, and the ending point is 50%, and the membership degree linearly decreases from 1 to 0 in this interval. Its physical meaning is that when the dust concentration is less than or equal to 30%, the system considers the concentration as "completely low concentration"; when the concentration is between 30% and 50%, the membership degree gradually decreases, indicating the transition from "low concentration" to "medium concentration".

[0102] μ_med(C) = triangle(40%, 60%, 80%); wherein, it represents the fuzzy set of "medium dust concentration", and the function type is triangular membership function. The left end point is 40% of the concentration, and the membership degree starts to rise from 0; the vertex is 60% of the concentration, at which the membership degree is 1, completely belonging to the medium concentration; the right end point is 80% of the concentration, and the membership degree linearly decreases from 1 to 0. Its physical meaning is that when the dust concentration is between 40% and 80%, the system considers the concentration as "medium concentration"; 60% is the typical value of the concentration, indicating the center point of the medium concentration.

[0103] μ_high(C) = trapezoid(70%, 80%, 100%). wherein, it represents the fuzzy set of "high dust concentration", and the function type is trapezoidal membership function. The left bottom edge has a starting point and an ending point of 70% and 80%, respectively, and the membership degree linearly increases from 0 to 1 in this interval. The starting point and the ending point of the right bottom edge are 80% and 100%, respectively, and the membership degree is constant at 1 when the concentration is greater than or equal to 80%. Its physical meaning is that when the dust concentration is greater than or equal to 80%, the system considers the concentration as "completely high concentration"; when the concentration is between 70% and 80%, the membership degree gradually increases, indicating the "high concentration warning transition zone".

[0104] 3) Rule base

[0105] IF C is high OR T>T_max OR W=0 THEN Gate=Open; This is the emergency dust removal rule, which triggers when any of the following conditions is detected: dust concentration is in the high interval (C≥80%), negative pressure module temperature exceeds the preset safety upper limit (T>T_max, e.g., T_max=120℃), engraving work module stops running (W=0, i.e., no new dust is generated), immediately open the gate (Gate=Open), and force the dust to settle in the screening module. The advantage of this rule is that it helps prevent the risk of dust concentration being too high to cause an explosion, avoids overheating of the equipment causing component damage, and automatically cleans residual dust when the machine is stopped, preparing for the next operation.

[0106] IF C is med AND dT / dt>threshold THEN Predictive_Open; This is the predictive gate opening rule, which triggers when the following two conditions are met: dust concentration is in the medium interval (40%≤C<80%); the rate of change of negative pressure module temperature exceeds the safety threshold (dT / dt>threshold, e.g., threshold=5℃ / s). When triggered, it initiates predictive dust removal to reduce dust concentration in advance. The advantage of this rule is that by monitoring the temperature change trend of the negative pressure module, the system can predict the risk of equipment overload and actively intervene when the dust concentration has not yet reached a dangerous value, thereby reducing the frequency of emergency dust removal and reducing mechanical wear. In addition, combined with the output of the LSTM prediction module, Δt_to_Tmax, the threshold is dynamically adjusted, further improving the response efficiency and accuracy of the system.

[0107] IF t>t_safe THEN Force_Cooldown. This is the forced cooling rule, which triggers when the continuous running time of the negative pressure module exceeds the safety duration (t>t_safe, e.g., t_safe=1800 seconds). When triggered, the system will force the cooling program (Force_Cooldown) to start, including: turning off the power of the negative pressure module, turning on the auxiliary cooling system, locking the gate to the open state, until the temperature drops to the safety range. The advantage of this rule is that it prevents the equipment from causing metal fatigue due to long-term continuous operation, ensuring the stability of the equipment and prolonging the service life. The hardware watchdog timer provides double protection, effectively avoiding overheating accidents caused by software failure, thereby improving the safety of the system.

[0108] 4) Optimization layer

[0109] The NSGA-II algorithm is used for online optimization of control parameters. NSGA-II (Non-dominated Sorting Genetic Algorithm II) is a multi-objective optimization algorithm that is suitable for optimizing multiple objective functions simultaneously and finding a set of balanced solutions (Pareto Front). During this process, NSGA-II finds the best balance between different objectives by simulating mechanisms from natural selection and genetics. Here are the specific steps of using the NSGA-II algorithm in the online optimization of control parameters process:

[0110] Step 1: Initialize population.

[0111] First, create an initial population. Each individual represents a set of control parameters, including concentration threshold C threshold , temperature threshold T threshold , and minimum run interval t min . When initializing the population, each parameter of an individual is randomly generated to ensure that the population covers a wide enough parameter space. These parameters will serve as decision variables for the NSGA-II algorithm.

[0112] Step 2: Evaluate population fitness.

[0113] For each individual, calculate its corresponding fitness value, which involves evaluating the objective functions. For each individual (set of control parameters), their fitness values are calculated through the objective functions f1, f2, and f3. These objective functions represent dust handling efficiency, equipment wear, and energy consumption, respectively. In NSGA-II, the fitness of each individual is evaluated through non-dominated sorting. Individuals are assigned to different ranks, with higher priority individuals being assigned smaller dominance values (i.e., better). At the same time, the crowding distance of each individual is calculated to maintain the diversity of the population.

[0114] Step 3: Non-dominated sorting.

[0115] Non-dominated sorting is performed on the individuals in the population, with the goal of dividing the population into multiple Pareto Front layers. The first layer contains non-dominated solutions (i.e., solutions that are not dominated by any other solution), the second layer contains solutions dominated by the first layer, and so on. Individuals in each layer are sorted according to their fitness, and the best solution is selected. During the optimization process, the search direction is guided by preferentially selecting individuals from the Pareto Front layers.

[0116] Step 4: Crowding distance calculation.

[0117] To maintain the diversity of solutions, the NSGA-II algorithm calculates the crowding distance of each individual. The crowding distance reflects how densely an individual is packed in the objective space, and individuals with smaller crowding distance represent a relatively sparse in the solution space, so they are more likely to be preserved. This helps to avoid local optimal solutions and enables the search to traverse a wider solution space.

[0118] Step 5: Selection operation.

[0119] Based on the results of non-dominated sorting and crowding distance calculation, the selection operation is performed. NSGA-II uses a tournament selection method to select individuals from the current population, with the selection probability based on the non-dominated sorting rank and crowding distance. It prefers to select individuals with higher ranks and tends to select individuals with smaller crowding distances. Through the selection operation, individuals with higher fitness are passed to the next generation.

[0120] Step 6: Crossover operation.

[0121] The crossover operation is performed on the selected individuals to generate new offspring. The crossover operation simulates gene recombination in natural genetics, combining the control parameters of two parent individuals into a new offspring individual. The crossover operation can be performed on decision variables (such as C threshold ,T threshold ,t min ) to explore the effects of different parameter combinations. The crossover rate is a parameter that controls the frequency of crossover operations.

[0122] Step 7: Mutation operation.

[0123] The mutation operation is used to introduce new genes and enhance the diversity of the population. Each individual undergoes a small change in its control parameters (for example, adjusting the concentration threshold, temperature threshold, or minimum running interval). The goal of mutation is to avoid the algorithm falling into a local optimal solution by introducing new search directions. The mutation rate controls the frequency of mutations.

[0124] Step 8: Generate new population.

[0125] The new individuals generated by the crossover and mutation operations are merged with the original population. Then, according to the calculation of non-dominated sorting and crowding distance, individuals in the merged population are selected to form a new population. These individuals will enter the next generation of the evolution process and undergo further optimization.

[0126] Step 9: Iterative optimization.

[0127] Steps 2 to 8 will be repeated in each generation until the stopping condition is reached. The stopping condition can be the maximum number of iterations or the fitness value reaching the pre-set accuracy requirement. In each generation, the population is gradually optimized, and the quality of the solution is continuously improved.

[0128] Step 10: Output the optimal solution.

[0129] When the algorithm converges, NSGA-II outputs a Pareto optimal solution set containing multiple combinations of control parameters that are not dominated by other solutions. By selecting the solution that best fits the current actual needs, the final control parameter values are determined. These control parameters will serve as the optimized control scheme for the system in actual operation.

[0130] Through the above steps, the NSGA-II algorithm can optimize the control parameters of the system online, balancing dust treatment efficiency, equipment wear and tear, and energy consumption, thereby achieving multi-objective optimization control.

[0131] 5) Decision variables

[0132] Concentration threshold C_threshold ∈ [70%, 90%]; temperature threshold T_threshold ∈ [50°C, 120°C]; minimum operation or action interval t_min ∈ [30s, 300s].

[0133] 6) Constraints

[0134] The constraints are set as: C ≤ 95% (safety constraint), T ≤ T_max (equipment constraint), t_cycle ≥ t_min (durability constraint).

[0135] (4) Predictive maintenance module

[0136] Join the LSTM prediction network for time series prediction:

[0137] The input is {C(t-n), T(t-n), W(t-n)} n=0,...,5, and the output is At_to_Cmax (time to reach concentration threshold) and At_to_Tmax (time to reach temperature threshold). In this predictive maintenance module, LSTM is used to predict the future dynamic behavior based on the past system states. The input to the LSTM network is the past state information, which includes the dust concentration C(t-n), the negative pressure module temperature T(t-n), and the working module state W(t-n) at the past 6 time points (n=0,...,5). The output of the LSTM model is two time prediction values: At_to_Cmax and At_to_Tmax. At_to_Cmax represents the time it takes for the system to reach the concentration threshold Cmax from the current time. This value predicts the trend of dust concentration in the future and determines when the set concentration safety threshold may be exceeded. At_to_Tmax represents the time it takes for the system to reach the temperature threshold Tmax from the current time. This value predicts the rising trend of the negative pressure module temperature and indicates when the set temperature safety threshold may be exceeded. These two output values are beneficial for the system to judge in advance whether measures need to be taken to prevent equipment overload.

[0138] Triggering pre-dust removal when the predicted time is less than the safety margin: if min(At_to_Cmax, At_to_Tmax) < τ_safe → early start of dust removal. Specifically, after predicting the time to reach the concentration threshold or the temperature threshold, the system will compare it with the safety margin τ_safe. The safety margin is to ensure that the equipment has enough time to respond and take appropriate protective measures before reaching the threshold. If min(At_to_Cmax, At_to_Tmax) < τ_safe, then early start of dust removal (Predictive Open). This condition means that if the predicted arrival time (whether it is the concentration threshold or the temperature threshold) is less than the preset safety margin, the system will start the dust removal operation in advance. In this way, the system can take measures before the dust concentration or temperature reaches the dangerous threshold, avoiding equipment overheating or high dust concentration, and ensuring safe operation of the equipment.

[0139] (5) Safety protection mechanism

[0140] Set up a hardware watchdog timer to ensure that when the maximum continuous opening time of the gate is less than or equal to 30s, the temperature exceeds 95% T_max, and the dust concentration exceeds 80%, the system will be forced to shut down and emergency dust removal.

[0141] (6) Parameter self-tuning module

[0142] Online optimization of weight coefficients using Q-learning algorithm:

[0143] The state space is discretized [C, T, t]; the state space refers to the set of all states that the system can be in. In this embodiment, the state space consists of three variables: dust concentration C, negative pressure module temperature T, and continuous running time of the negative pressure module t. To facilitate the application of the Q-learning algorithm, the state space will be discretized for these three variables, i.e., their continuous value range is divided into multiple discrete intervals. For example, the dust concentration C can be discretized into several intervals (e.g., 0-30%, 30%-50%, etc.), and the temperature T and time t are also divided accordingly. This discretized state space allows the Q-learning algorithm to learn and make decisions in a finite set of states.

[0144] The action space is {adjust w1, adjust w2, adjust w3}; the action space refers to all possible actions that the system can take at each state. In this embodiment, the action space includes adjusting the weight coefficients w1, w2, and w3, which correspond to the influence of dust concentration, temperature, and switch frequency on the reward function, respectively. Specifically, the Q-learning algorithm will optimize the control strategy by adjusting these weight coefficients at each discretized state. By dynamically adjusting these weights, the algorithm can balance the system's goals (such as dust handling efficiency, equipment wear and tear, and energy consumption) under different operating conditions to achieve optimal system performance.

[0145] The reward function is as follows: R = η1*(C_avg / C_max) + η2*(T_avg / T_max) + η3*(1 / N_switch). Where C avg represents the average value of the dust concentration in the system, reflecting the overall level of dust concentration within a certain period. C max max is the maximum safe threshold of dust concentration, which is the maximum dust concentration that the system can accept. Its purpose is to ensure that the dust concentration does not exceed the safety limit. η1 is a weight coefficient that adjusts the importance of the dust concentration reward value in the total reward. By optimizing w1, the system's sensitivity to dust concentration can be controlled. avg represents the average value of the negative pressure module temperature of the system, reflecting the temperature level of the device within a certain period. T max max is the maximum safe temperature threshold of the device, ensuring that the device does not malfunction or be damaged due to excessive temperature. η2 is a weight coefficient that adjusts the influence of the temperature control reward value in the total reward. By optimizing w2, the role of temperature control in overall system optimization can be adjusted. switchThe number of switching times of the device is used to measure the frequency of device start and stop. Frequent switching can cause device wear and tear and increase energy consumption. η3 is a weight coefficient for controlling the influence of the number of switching times on the reward value. By optimizing w3, the tolerance of the system to frequent switching of the device can be adjusted to reduce unnecessary device start. The reward function considers dust concentration, temperature control and device switching frequency in a weighted manner, and the optimization algorithm will find the best control strategy by adjusting the weight coefficients (w1, w2, w3) to maximize the overall performance of the system.

[0146] The above technical solution has the advantages of:

[0147] The embodiment of the application solves the problem of dust treatment in large-scale production of jade carving, and realizes the resource utilization process and reuse of jade carving dust.

[0148] The embodiment of the application flexibly adapts to different production scales of jade processing environment, ensures that high processing capacity can be maintained under diversified working conditions, integrates intelligent sensing and feedback mechanism to realize full-process automatic monitoring and reduce the need for manual intervention, adopts a fully enclosed dust treatment path to effectively suppress the diffusion of pollutants and meet strict environmental protection standards, combines dynamic optimization algorithm and intelligent early warning mechanism to continuously optimize energy allocation and prevent abnormal wear of equipment, thereby prolonging the service life of core components and reducing the overall operation and maintenance cost.

[0149] As shown in Figure 3 The embodiment provides a working method of the centralized jade processing solid waste resource utilization system, which comprises the following steps:

[0150] S1: The dust suction module sucks the jade dust generated by the jade processing work module through the pipeline;

[0151] S2: The negative pressure module generates suction force to transport the jade dust to the dust collection module;

[0152] S3: The dust collection module temporarily stores the jade dust;

[0153] S4: The gate serves as a switch for controlling the jade dust to enter the screening module from the dust collection module, and the gate is opened when the preset opening condition is met, so that the jade dust enters the screening module under the action of gravity;

[0154] S5: The screening module screens and classifies the jade dust to obtain the jade dust corresponding to the first particle size range, the second particle size range and the third particle size range respectively;

[0155] S6: The recycling module recycles the jade dust in the first particle size range for first resource utilization treatment, and recycles the jade dust in the second particle size range for second resource utilization treatment.

[0156] S7: The precipitation module performs a third resource treatment on the third particle size range of the jade dust; wherein the first particle size range is larger than the second particle size range, and the second particle size range is larger than the third particle size range.

[0157] The first resource treatment obtains coarse sand, which can be used as polishing and polishing base material, building filling material, water permeable brick synthesis raw material, soil conditioner, heavy metal adsorbent, etc.

[0158] The second resource treatment obtains fine sand, which can be used as ceramic clay, plastic / rubber filler, mineral pigment, glass fiber reinforced material, etc.

[0159] The third resource treatment obtains mud-level dust, which is used for porcelain making, functional coating filler, sanding paste filler, cosmetic filler, high-grade polishing powder, etc.

[0160] The particle size range of the coarse sand is larger than that of the fine sand, and the particle size range of the coarse sand is larger than that of the fine sand as a whole, wherein the minimum particle size value of the coarse sand is larger than the maximum particle size value of the fine sand, and the particle size distribution interval of the two does not overlap.

[0161] The working process of the first resource treatment and the second resource treatment is basically similar, and the difference lies in the use of different filter screens. The first resource treatment uses a filter screen with a mesh size of 200, for example, which can intercept the coarsest dust particles. The filter screen is placed at an angle of 45°, so that the intercepted dust particles can automatically roll down into the recycling module under the action of gravity, avoiding excessive accumulation on the filter screen, which prevents subsequent dust from passing through the filter screen. The second resource treatment uses a filter screen with a mesh size of 500, for example, which is used to intercept fine jade dust.
