Description

Technical Field

[0001] This invention relates to the field of solid hazardous waste management technology, specifically to a method and system for the temporary storage, collection, and management of solid hazardous waste based on a hazardous waste temporary storage facility. Background Technology

[0002] With the increasing sophistication of industrial production, the types and quantities of hazardous waste generated continue to grow. As a key intermediate link from the generation to the final disposal of hazardous waste, the compliance, safety and efficiency of temporary storage directly affect ecological and environmental safety and corporate operating costs. With increasingly stringent environmental regulations and the continuous growth of hazardous waste generation, traditional management models and related technologies are no longer able to meet the needs of refined and intelligent management.

[0003] Currently, efforts have been made to optimize the management of temporary storage of solid hazardous waste through information technology. For example, Chinese invention patent with publication number CN118586644A discloses "a temporary storage equipment room and a management system and method for the collection and temporary storage of hazardous waste". The technical solution of this invention is to build a management framework that includes a temporary storage equipment room and an Internet of Things cloud platform to realize the basic recording and alarm functions of hazardous waste collection and temporary storage.

[0004] However, in practical applications, the above-mentioned schemes fail to consider environmental temperature and humidity fluctuations and the coupling characteristics of hazardous waste categories to reasonably calculate safe capacity, making it impossible to achieve dynamic and precise management. Furthermore, the collection route planning does not incorporate multi-objective optimization algorithms, resulting in low collection and transportation efficiency and delays in the transfer of high-risk hazardous waste. Additionally, the schemes fail to classify risks such as overcapacity, overtemperature, and mixed storage according to their severity, making it impossible to trigger differentiated disposal instructions based on the severity level. This hinders the realization of intelligent management of solid hazardous waste from storage to transfer, making it difficult to effectively reduce environmental risks and the incidence of safety accidents during the temporary storage of solid hazardous waste.

[0005] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a method and system for the temporary storage, collection and management of solid hazardous waste based on a hazardous waste temporary storage room, so as to solve the technical defects mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a solid hazardous waste temporary storage and collection management system based on a hazardous waste temporary storage room, including a multi-dimensional perception module for the temporary storage room, a dynamic assessment module for temporary storage safety, a precise classification module for solid waste categories, an intelligent planning module for collection routes, and a full-process control module;

[0008] The multi-dimensional sensing module of the temporary storage room collects multi-dimensional data within the hazardous waste temporary storage room, and simultaneously completes the invalid value screening, outlier marking, and format standardization processing of the raw data; the temporary storage safety dynamic judgment module dynamically and quantitatively calculates the safe temporary storage capacity of solid hazardous waste at each storage point, determines the risk of over-capacity, and outputs the over-capacity risk value.

[0009] The solid waste category precise placement module is used to accurately classify and place external hazardous waste into the independent storage points within the temporary storage room, while determining the risk of mixed storage at each storage point and calculating the risk value of mixed storage. The collection route intelligent planning module is used to generate the optimal collection path and standardized execution instructions based on multi-objective optimization planning analysis of the route when the hazardous waste stored in the temporary storage room reaches the preset collection conditions. These instructions are then sent to the full-process control module to guide collection equipment or personnel to collect the hazardous waste from the relevant storage points and transport it to the temporary storage room transfer outlet.

[0010] Furthermore, the multi-dimensional sensing module in the temporary storage room deploys dedicated sensing equipment within the hazardous waste temporary storage room, including a high-precision bulk density sensor, an infrared physical property identification sensor, a weight sensor, a temperature and humidity sensor, a channel congestion monitoring camera, and a positioning sensor.

[0011] The collected raw data is transmitted to the built-in preprocessing unit through the industrial IoT gateway. The preprocessing unit filters invalid values ​​from the raw data based on the preset reasonable threshold range of each parameter, and performs format standardization processing on the valid data, converting it into JSON data format. At the same time, it adds a collection timestamp, a unique code for the collection point, and a unique sensor identification number to each set of valid data, generating a standardized sensing dataset and transmitting it in real time to the temporary storage safety dynamic judgment module and the solid waste category accurate classification module.

[0012] Furthermore, the specific operation process of the temporary security dynamic assessment module is as follows:

[0013] For the collected data at each storage point, the hazardous waste bulk density correction coefficient Kρ, the ambient temperature correction coefficient Kt, and the ambient relative humidity correction coefficient Kh are calculated according to the preset calculation rules. At the same time, the corresponding storage point category classification data transmitted by the solid waste category accurate classification module are received to determine the hazardous waste category coupling correction coefficient Kc of the storage point. The real-time safe temporary storage capacity Vsafe of each storage point is obtained based on the safe temporary storage capacity calculation formula.

[0014] Furthermore, the actual temporary storage volume Vact at each storage point is compared with the calculated Vsafe. If Vact / Vsafe≤1, the storage point is determined to have no overcapacity risk. If Vact / Vsafe>1, the corresponding storage point is determined to have overcapacity risk, and the overcapacity risk value Pov of the corresponding storage point is calculated according to Pov=Vact / Vsafe.

[0015] Furthermore, the real-time safe temporary storage capacity Vsafe, overcapacity risk assessment results, and overcapacity risk value Pov of each storage point are classified according to the storage point code and transmitted in real time to the solid waste category accurate placement module, the collection flow intelligent planning module, and the full process control module.

[0016] Furthermore, the specific operation process of the solid waste category precise sorting module is as follows:

[0017] The system performs category compatibility assessments on external hazardous waste awaiting storage, classifying it into compatible and incompatible categories with existing hazardous waste in the temporary storage area. Based on the remaining temporary storage capacity Vres at each storage point, the category matching results of the hazardous waste awaiting storage, and the compatibility assessment results, the system allocates dedicated storage points or shared storage points for compatible categories to external hazardous waste awaiting storage. Simultaneously, it generates standardized placement instructions that include placement location, placement quantity, and operating procedures, and pushes them to the end-to-end control module to guide manual or intelligent handling equipment to accurately transport external hazardous waste to the corresponding storage points.

[0018] After the sorting operation is completed, the sorting status of each storage point is automatically checked to determine whether there is a mixed storage problem. If mixed storage is found, the mixed storage risk value Pc of the corresponding storage point is calculated according to the mixed storage type. At the same time, based on the final sorting verification results of each storage point, the hazardous waste category coupling correction coefficient Kc of the corresponding storage point is determined and transmitted to the temporary storage safety dynamic assessment module in real time. The final sorting data, sorting verification results and mixed storage risk value Pc of each storage point are transmitted in real time to the intelligent planning module for collection flow and the full process control module according to the storage point code.

[0019] Furthermore, the specific operation process of the intelligent traffic flow planning module is as follows:

[0020] The core planning objectives of the collection route are determined, and the storage points for hazardous waste to be collected in the temporary storage room are divided into several independent collection units. Combining real-time data of the channel environment and physical parameters of the channel, the actual distance Li, the estimated time Ti and the risk value Ri are calculated for each segment between each collection unit through three-dimensional coordinate calculation and image recognition analysis.

[0021] Substitute all calculation parameters into the comprehensive cost calculation formula for the optimal path, and calculate the comprehensive cost C of each candidate collection path. By comparing the values, select the candidate path with the smallest comprehensive cost C as the optimal collection route Copt, generate a visual path map of the optimal collection route and standardized execution instructions, and push them to the full-process control module to guide the standardized execution of collection operations.

[0022] Furthermore, the full-process control module is connected to the emergency response and linkage module. The emergency response and linkage module performs emergency response and linkage judgment on each storage point and the overall space in the temporary storage room, triggers corresponding differentiated linkage and linkage instructions for different emergency response levels, and sends relevant analysis and handling information to the full-process control module.

[0023] Furthermore, the specific analysis process of the emergency response and coordination module is as follows:

[0024] The system receives environmental anomaly data from each storage point transmitted by the multi-dimensional sensing module in the temporary storage area, overcapacity risk values ​​(Pov) of each storage point transmitted by the temporary storage safety dynamic assessment module according to the storage point code, and mixed storage risk values ​​(Pc) of each storage point transmitted by the solid waste category precise placement module according to the storage point code.

[0025] For each storage point, the critical situation warning output value G of each storage point is obtained through analysis and calculation. Based on the critical situation analysis results of each storage point in the temporary storage room, the overall critical situation of the temporary storage room is comprehensively judged. The overall critical situation decision result of no warning, first-level warning, second-level warning or third-level warning is generated through analysis. Based on the overall critical situation decision result, the corresponding differentiated linkage disposal instructions are triggered and output to the full process control module.

[0026] Furthermore, the analysis and acquisition process of the crisis warning output value is as follows:

[0027] Obtain the over-capacity risk value Pov and the mixed storage risk value Pc of the corresponding storage point, as well as the local real-time temperature t and local real-time humidity h of the corresponding storage point, and retrieve the corresponding safe temperature threshold tb and safe humidity threshold hb. Calculate the over-temperature risk value Pt and the high humidity risk value Ph by Pt=t / tb and Ph=h / hb respectively.

[0028] Substitute the overcapacity risk value Pov, overtemperature risk value Pt, high humidity risk value Ph, and mixed storage risk value Pc of the corresponding storage point, along with the corresponding weighting coefficients α, β, γ, and δ, into the early warning level determination formula to calculate the critical situation early warning output value G for the corresponding storage point.

[0029] Furthermore, the specific process for analyzing and generating the overall crisis decision-making results is as follows:

[0030] Obtain the crisis analysis results of each storage point in the temporary storage room. If the crisis warning output value G≤3, mark the corresponding storage point as a safe point. If the crisis warning output value G>3, mark the corresponding storage point as a crisis-related point. If there are no crisis-related points in the temporary storage room, generate an overall crisis decision result without warning.

[0031] If there are critical situation related points in the temporary storage room, the number of critical situation related points in the temporary storage room is marked as the critical situation related number measurement value, and the critical situation warning output value G of the critical situation related points is subtracted by 3 to obtain the critical situation exceedance value. The critical situation exceedance value of all critical situation related points is averaged to obtain the critical situation exceedance characteristic value, and the critical situation exceedance value with the largest value is marked as the critical situation exceedance characteristic value.

[0032] The comprehensive decision value for a crisis is calculated by weighting and summing the crisis correlation values, the crisis excess characteristic values, and the crisis excess amplitude characteristic values. If the comprehensive decision value for a crisis does not exceed the minimum value of the preset comprehensive decision value range, a level-one warning overall crisis decision result is generated.

[0033] If the overall crisis decision value is within the preset range, a Level II warning overall crisis decision result is generated; if the overall crisis decision value exceeds the maximum value of the preset range, a Level III warning overall crisis decision result is generated.

[0034] The present invention also proposes a method for the temporary storage, collection and management of solid hazardous waste in a hazardous waste temporary storage room, including the following steps:

[0035] Step 1: Multi-dimensional perception and data preprocessing;

[0036] Step 2: Dynamic assessment of the safe temporary storage capacity at each storage point;

[0037] Step 3: Accurately categorize and classify external hazardous waste upon entry into the warehouse;

[0038] Step 4: Intelligent planning of the hazardous waste collection and evacuation route within the temporary storage room;

[0039] Step 5: Triage and coordinated response to emergencies.

[0040] Compared with the prior art, the beneficial effects of the present invention are:

[0041] 1. In this invention, multi-dimensional perception in the temporary storage area enables accurate collection and standardized processing of all-dimensional data. Based on dynamic calculation of safe capacity and determination of overcapacity risk, and in accordance with compatibility standards, hazardous waste is accurately disposed of and mixed storage hazards are investigated to ensure compliance of temporary storage. Furthermore, by combining multi-objective optimization to generate optimal paths and standardized instructions, collection and transportation efficiency is improved and operational risks are reduced.

[0042] 2. In this invention, multi-dimensional risk data is integrated through the hazardous situation classification and linkage response module to quantitatively determine the hazardous situation level of each storage point and the overall situation, trigger differentiated disposal instructions, avoid improper disposal, and coordinate the coordinated operation of each link through the full-process control module to achieve intelligent and refined management from warehousing to transfer, thereby improving the compliance, efficiency and safety of hazardous waste temporary storage and collection management. Attached Figure Description

[0043] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings;

[0044] Figure 1 This is an overall system block diagram of the present invention;

[0045] Figure 2 This is a flowchart of the method of the present invention. Detailed Implementation

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Example 1: As Figure 1 As shown, the solid hazardous waste temporary storage and collection management system based on the hazardous waste temporary storage room proposed in this invention includes a multi-dimensional perception module for the temporary storage room, a dynamic assessment module for temporary storage safety, a precise classification module for solid waste categories, an intelligent planning module for collection routes, a graded and coordinated response module for hazardous situations, and a full-process control module.

[0048] The multi-dimensional sensing module of the temporary storage room is used to collect real-time data on the physical parameters of solid hazardous waste and local environmental parameters of each independent storage point in the temporary storage room, as well as the environmental parameters and channel parameters of the entire space of the temporary storage room. At the same time, it completes the invalid value screening, outlier marking and format standardization of the raw data, providing accurate and unified raw data support for other modules, and solving the problems of single data collection dimension, inconsistent format and low data quality in the existing technology.

[0049] Specifically, the multi-dimensional sensing module in the temporary storage room deploys dedicated sensing devices at each solid hazardous waste storage point, the overall environmental monitoring point of the temporary storage room, and the passage area. These devices include high-precision bulk density sensors, infrared physical property identification sensors, weight sensors, temperature and humidity sensors, passage congestion monitoring cameras, and positioning sensors. Preferably, all sensing devices continuously collect data at a preset frequency of 5 minutes.

[0050] Among them, the bulk density sensor, infrared physical property identification sensor and weight sensor are deployed independently at each storage point. They respectively collect the actual bulk density ρ and infrared characteristic spectral value S of the solid hazardous waste at the corresponding storage point and match them with the built-in hazardous waste category database and actual weight m. The actual bulk density ρ is converted into the actual temporary storage volume Vact of the corresponding storage point.

[0051] Temperature and humidity sensors simultaneously collect data from individual points and the entire system. Temperature and humidity sensors deployed at each storage point collect the local real-time temperature t and relative humidity h at the corresponding location. Temperature and humidity sensors deployed at the overall environmental monitoring point of the temporary storage room collect the overall temperature and humidity of the entire space. Positioning sensors and channel congestion monitoring cameras are deployed in the channel area to collect the three-dimensional coordinate values ​​(x, y, z) of each storage point and channel node, as well as the real-time passage status of the channel.

[0052] The collected raw data is transmitted to the built-in preprocessing unit through the industrial IoT gateway. The preprocessing unit filters invalid values ​​from the raw data based on the preset reasonable threshold range of each parameter. It marks and removes abnormal data collected from sensor failure, signal interference, and signal interference as invalid data, and performs format standardization processing on the valid data, converting it into JSON data format.

[0053] Simultaneously, a collection timestamp, a unique code for the collection point, and a unique sensor identification number are added to each set of valid data to generate a standardized sensing dataset. This dataset is temporarily stored locally through edge computing nodes and simultaneously transmitted in real time to the temporary storage safety dynamic assessment module, the solid waste category precise placement module, and the emergency response and linkage module, providing basic data support for the calculation and analysis of subsequent modules.

[0054] The dynamic assessment module for temporary storage safety, based on a standardized sensing dataset, dynamically and quantitatively calculates the safe temporary storage capacity of solid hazardous waste at each independent storage point within the temporary storage area using a predefined formula. It accurately determines the over-capacity risk of each storage point and calculates the over-capacity risk value. Simultaneously, it transmits the calculation results and risk assessment data for each storage point to other relevant modules, enabling refined, dynamic, and independent management of the temporary storage capacity at each point. This avoids the shortcomings of existing technologies that use fixed thresholds to determine temporary storage risk. Specifically, the operation process of the dynamic assessment module for temporary storage safety is as follows:

[0055] First, after receiving the standardized sensing dataset transmitted by the multi-dimensional sensing module in the temporary storage area, the data is split according to the unique code of the storage point, and the basic approved capacity Vbase, actual bulk density ρ of solid hazardous waste, local real-time temperature t, local real-time humidity h, hazardous waste category information, and actual temporary storage volume Vact of each independent storage point are extracted.

[0056] Subsequently, for the collected data of each storage point, the hazardous waste bulk density correction coefficient Kρ, the ambient temperature correction coefficient Kt, and the ambient relative humidity correction coefficient Kh are calculated respectively in combination with the preset calculation rules. At the same time, the corresponding storage point category classification data transmitted by the solid waste category accurate classification module are received to determine the hazardous waste category coupling correction coefficient Kc of the storage point.

[0057] Then, substitute all the above parameters into the safety buffer capacity calculation formula to calculate the real-time safety buffer capacity Vsafe for each storage point. The specific formula is as follows:

[0058] ;

[0059] Among them, Vbase: the basic approved capacity of a single storage point, in accordance with the "Standard for Pollution Control of Hazardous Waste Storage" (GB18597-2023), is set at 3 tons, and is converted into volume units based on the standard bulk density of the corresponding solid hazardous waste in the built-in hazardous waste category database, without manual intervention, to ensure the compliance of the value;

[0060] Kρ: Hazardous waste bulk density correction coefficient, dimensionless, calculated as Kρ=ρ / ρb, where ρ is the actual bulk density collected in real time by the high-precision bulk density sensor deployed by the multi-dimensional sensing module in the temporary storage room at the corresponding storage point, and ρb is the standard bulk density of the corresponding category of solid hazardous waste in the built-in hazardous waste category database.

[0061] Kt: Ambient temperature correction coefficient, dimensionless, calculated based on the local real-time temperature t collected by the temperature and humidity sensors deployed at the corresponding storage point by the multi-dimensional sensing module in the temporary storage room, and the safe temperature threshold tb of the corresponding category of hazardous waste in the built-in hazardous waste category database. If t≤tb, then Kt=1; if t>tb, then Kt=1-(t-tb) / tb, where tb is directly retrieved from the built-in hazardous waste category database.

[0062] Kh: Aspect relative humidity correction factor, dimensionless, the calculation rule is the same as Kt. If h≤hb, then Kh=1; if h>hb, then Kh=1-(h-hb) / hb.

[0063] Among them, hb is the local relative humidity collected in real time by the temperature and humidity sensor deployed by the multi-dimensional sensing module in the temporary storage room at the corresponding storage point, and hb is the safe humidity threshold of the corresponding category of hazardous waste in the built-in hazardous waste category database, which is directly retrieved from the built-in hazardous waste category database.

[0064] Kc: Hazardous waste category coupling correction coefficient, dimensionless, determined by the category classification verification data of the corresponding storage point transmitted by the solid waste category accurate classification module. If the hazardous waste in the storage point is a single category, then Kc=1; if it is a mixture of compatible categories as specified in the built-in "Hazardous Waste Compatibility Table", then Kc=0.9; if it is a mixture of incompatible categories, then Kc=0.6.

[0065] Next, the actual temporary storage volume Vact at each storage point is compared with the calculated Vsafe. If Vact / Vsafe≤1, the storage point is determined to have no overcapacity risk. If Vact / Vsafe>1, the corresponding storage point is determined to have overcapacity risk. The overcapacity risk value Pov for the corresponding storage point is calculated according to Pov=Vact / Vsafe (if Pov≤1, then Pov=0; if Pov>1, then the actual calculated value is used).

[0066] Furthermore, the real-time safe temporary storage capacity Vsafe, overcapacity risk assessment results, and overcapacity risk value Pov of each storage point are classified according to the storage point code and transmitted in real time to the solid waste category accurate placement module, the collection flow intelligent planning module, the emergency response module and the whole process control module.

[0067] The solid waste category precise placement module is responsible for transferring external hazardous waste to the temporary storage room. Based on the hazardous waste property data from the multi-dimensional sensing module of the temporary storage room and the safe temporary storage capacity data of each storage point from the temporary storage safety dynamic judgment module, combined with the national hazardous waste compatibility standard requirements, it realizes the category zoning and precise placement of external hazardous waste to each independent storage point in the temporary storage room.

[0068] Simultaneously, it accurately determines the risk of mixed storage at each storage point and calculates the risk value, providing the judgment module with a hazardous waste category coupling correction coefficient Kc for each storage point, and providing the intelligent planning module for collection routes with accurate category zoning data within the temporary storage room, achieving multi-module data collaboration; specifically, the operation process of the solid waste category accurate placement module is as follows:

[0069] First, it receives the infrared characteristic spectral values ​​and category matching results of the external hazardous waste to be stored from the multi-dimensional perception module in the temporary storage room, as well as the basic data of each storage point in the temporary storage room. At the same time, it receives the real-time safe temporary storage capacity Vsafe and the remaining temporary storage capacity Vres of each storage point from the temporary storage safety dynamic judgment module. It should be noted that Vres = Vsafe - Vact.

[0070] Next, the compatibility of external hazardous waste to be stored is determined by the built-in "Hazardous Waste Compatibility Table". In strict accordance with the hazardous waste management standards, the hazardous waste to be stored and the hazardous waste already stored in the temporary storage room are divided into compatible category groups and incompatible category groups, and the prohibited categories of hazardous waste are clearly defined.

[0071] Subsequently, based on the remaining temporary storage capacity Vres of each storage point, the category matching results of the hazardous waste to be put into storage, and the compatibility determination results, dedicated storage points or shared storage points for compatible categories are allocated to external hazardous waste to be put into storage. At the same time, standardized placement instructions containing placement location, placement quantity, and operation specifications are generated and pushed to the full-process control module to guide manual or intelligent handling equipment to accurately transport external hazardous waste to the corresponding storage point and complete the hazardous waste storage and placement operation.

[0072] After the sorting operation is completed, the infrared physical property identification sensor and positioning sensor deployed at the corresponding storage point through the multi-dimensional perception module of the temporary storage room are used to automatically check the sorting status of each storage point and determine whether there is a mixed storage problem. If there is mixed storage, the mixed storage risk value Pc of the corresponding storage point is calculated according to the mixed storage type (preferably, Pc=0 when there is no mixed storage, Pc=0.5 when compatible categories are mixed, and Pc=1 when incompatible categories are mixed). At the same time, based on the final sorting verification results of each storage point, the hazardous waste category coupling correction coefficient Kc of the corresponding storage point is determined and transmitted to the temporary storage safety dynamic judgment module in real time.

[0073] Furthermore, the final category classification data, classification verification results, and mixed storage risk value Pc of each storage point are transmitted in real time to the intelligent collection flow planning module, the emergency response and linkage module, and the full-process control module according to the storage point code classification, ensuring that each module obtains the latest and most accurate category zoning information in the temporary storage room.

[0074] The intelligent planning module for the collection route is responsible for optimizing the collection and transportation route of hazardous waste in the temporary storage room when the stored hazardous waste reaches the preset collection conditions (such as the storage point being overloaded or the preset collection cycle is reached). Based on the category zoning data of each storage point, the temporary storage volume and safe temporary storage capacity data of each storage point, and the real-time data of the temporary storage room passage environment, the module uses the set optimal path comprehensive cost calculation formula to achieve multi-objective optimization planning of the collection and transportation route of hazardous waste in the temporary storage room.

[0075] Furthermore, it generates optimal collection paths and standardized execution instructions to guide collection equipment / personnel in transporting hazardous waste from various storage points to the transfer exit of the temporary storage room. This improves collection efficiency while reducing various safety risks during the collection process, making it particularly suitable for multi-category, small-batch collection scenarios in temporary storage rooms for micro and small enterprises and shared temporary storage rooms in industrial parks. Specifically, the operation process of the intelligent planning module for collection routes is as follows:

[0076] First, it receives data on the category zoning of each storage point, the hazardous waste category and actual temporary storage volume of each storage point from the solid waste category accurate placement module. At the same time, it receives data on the actual temporary storage volume Vact and real-time safe temporary storage capacity Vsafe of each storage point from the temporary storage safety dynamic assessment module. It also extracts data such as the three-dimensional coordinates of each storage point, channel congestion status and channel physical parameters from the multi-dimensional perception module of the temporary storage area.

[0077] First, the core planning objective of the collection route is determined: to minimize the overall cost, while strictly adhering to the principles of "collecting compatible categories in the same vehicle, collecting incompatible categories in separate vehicles, prioritizing collection at overcapacity storage points, and prioritizing collection of high-risk categories". All planned routes are internal routes within the temporary storage room, with the starting point being the starting position of the collection operation within the temporary storage room and the ending point being the transfer exit of the temporary storage room.

[0078] Based on the above principles, the storage points for hazardous waste that need to be collected in the temporary storage room are divided into several independent collection units. Combining real-time data of the channel environment and physical parameters of the channel, through three-dimensional coordinate calculation and image recognition analysis, the actual distance Li, the estimated time Ti and the risk value Ri are calculated for each segment between each collection unit.

[0079] Subsequently, all calculation parameters are substituted into the formula for calculating the comprehensive cost of the optimal path, and the comprehensive cost C of each candidate collection path is calculated respectively, as follows:

[0080] ;

[0081] Where, n: the number of road segments in the collection route, which is automatically counted by the module based on the distribution of storage points in the temporary storage room, the division of collection units and the channel planning, without manual intervention;

[0082] Cd: Unit distance transportation cost, which is obtained from the actual operating cost statistics of the enterprise, including labor costs, equipment depreciation costs, energy costs, etc., and is stored in the built-in cost database. It supports managers to manually enter and update the cost based on the enterprise's operating conditions.

[0083] Li: The actual distance of the i-th road segment is calculated by spatial distance from the three-dimensional coordinate values ​​(x, y, z) of each collection unit and channel node collected by the positioning sensor of the multi-dimensional perception module in the temporary storage room, ensuring the accuracy of the value;

[0084] Ct: Cost per unit of time, calculated from the actual operating costs of the enterprise, is the same as Cd and includes labor time costs, equipment standby costs, etc. It is stored in the built-in cost database and supports managers to manually enter and update it according to the enterprise's operating conditions.

[0085] Ti: The estimated time for the i-th road segment is obtained by combining the actual distance Li of the road segment and the rated driving speed of the collection device with the channel congestion status collected by the multi-dimensional perception module in the temporary storage room. When the channel congestion status is smooth, the rated driving speed of the collection device is taken. When congested, the driving speed is reduced according to the degree of congestion. The degree of congestion is determined by the camera of the multi-dimensional perception module in the temporary storage room through image recognition technology.

[0086] Cr: Unit risk coefficient cost, retrieved from the module's built-in safety assessment database, is determined to be a fixed value based on the safety level of the temporary storage area and the risk level of the hazardous waste category, ensuring the standardization of risk cost accounting;

[0087] Ri: Risk value of the i-th road segment, ranging from 1 to 5. It is determined by a combination of physical parameters of the passage collected by the camera and positioning sensor of the multi-dimensional perception module in the temporary storage room, and risk level data of the surrounding storage points. Level 1 is the lowest risk (i.e., the value is 1), and Level 5 is the highest risk (i.e., the value is 5). The determination criteria are the width and flatness of the passage, whether it is close to high-risk hazardous waste storage points, and whether there are obstacles. The determination rules are built into the module and there is no manual intervention.

[0088] Finally, by comparing numerical values, the candidate path with the lowest overall cost C is selected as the optimal collection route Copt. A visual path diagram of the optimal collection route and standardized execution instructions including path sequence, collection unit, operation requirements, and safety specifications are generated and simultaneously pushed to the full-process control module to guide the standardized execution of collection operations.

[0089] The hazardous situation classification and response linkage module classifies and determines the hazardous situation at each storage point and the entire space within the temporary storage area. It triggers differentiated linkage response instructions based on different hazardous situation levels and sends relevant analysis and response information to the full-process management module. This achieves both precise risk location and localized response at each storage point, and comprehensive control and coordinated response to the overall risk of the temporary storage area. This facilitates rapid, accurate, and standardized hazardous situation handling, avoids over- or under-handling, and reduces environmental risks and the incidence of safety accidents during hazardous waste storage. Specifically, the analysis process of the hazardous situation classification and response linkage module is as follows:

[0090] First, it receives environmental anomaly data of each storage point transmitted by the multi-dimensional perception module in the temporary storage area, overcapacity risk value Pov of each storage point transmitted by the temporary storage safety dynamic judgment module according to the storage point code, and mixed storage risk value Pc of each storage point transmitted by the solid waste category accurate placement module according to the storage point code.

[0091] For each storage point, obtain the over-capacity risk value Pov and the mixed storage risk value Pc, as well as the local real-time temperature t and local real-time humidity h of the corresponding storage point. Also, retrieve the corresponding safe temperature threshold tb and safe humidity threshold hb. Calculate the over-temperature risk value Pt (if t≤tb, then Pt=0; if t>tb, then the actual calculated value) and the high humidity risk value Ph (if h≤hb, then Ph=0; if h>hb, then the actual calculated value) using Pt=t / tb and Ph=h / hb respectively.

[0092] Then, the overcapacity risk value Pov, overtemperature risk value Pt, high humidity risk value Ph, and mixed storage risk value Pc of the corresponding storage point, along with the corresponding weighting coefficients α, β, γ, and δ, are substituted into the warning level determination formula to calculate the corresponding critical situation warning output value G for the storage point. It should be noted that the warning level determination formula is as follows:

[0093] G=α×Pov+β×Pt+γ×Ph+δ×Pc;

[0094] Wherein, α+β+γ+δ=1, is determined according to the degree of impact of each risk factor on the safety of temporary storage of hazardous waste. Among them, the risk of exceeding the capacity is the core risk, with α=0.4, the risk of exceeding the temperature is β=0.25, the risk of high humidity is γ=0.15, and the risk of mixed storage is δ=0.2. Preferably, the weighting coefficients support the dynamic adjustment by managers according to the actual safety management requirements of the enterprise and historical early warning data.

[0095] Obtain the hazard analysis results of each storage point in the temporary storage room. If the hazard warning output value G≤3, mark the corresponding storage point as a safe point. If the hazard warning output value G>3, mark the corresponding storage point as a hazard-related point. If there are no hazard-related points in the temporary storage room, it indicates that there is no hazard in the temporary storage room, and generate an overall hazard decision result without warning.

[0096] Furthermore, if there are critical situation related points in the temporary storage room, the number of critical situation related points in the temporary storage room is marked as the critical situation related number measurement value, and the critical situation warning output value G of the critical situation related points is subtracted by 3 to obtain the critical situation exceedance value. The critical situation exceedance value of all critical situation related points is averaged to obtain the critical situation exceedance characteristic value, and the critical situation exceedance value with the largest value is marked as the critical situation exceedance characteristic value.

[0097] The comprehensive decision value for a crisis is obtained by weighting and summing the measured values ​​of the crisis correlation number, the crisis over-condition characteristic value, and the crisis over-amplitude characteristic value. Specifically, the corresponding preset weight coefficients are assigned to the measured values ​​of the crisis correlation number, the crisis over-condition characteristic value, and the crisis over-amplitude characteristic value. The measured values ​​of the crisis correlation number, the crisis over-condition characteristic value, and the crisis over-amplitude characteristic value are then multiplied by their respective preset weight coefficients, and the sum of the three sets of products is marked as the comprehensive decision value for the crisis.

[0098] It should be noted that the higher the value of the comprehensive crisis decision value, the more serious the overall urgency of the crisis in the hazardous waste storage area. The comprehensive crisis decision value is compared with the preset comprehensive crisis decision value range. If the comprehensive crisis decision value does not exceed the minimum value of the preset comprehensive crisis decision value range, it indicates that the overall urgency of the crisis in the hazardous waste storage area is relatively mild, and a level one warning overall crisis decision result is generated.

[0099] If the overall crisis decision value is within the preset range, it indicates that the overall urgency of the situation in the hazardous waste storage area is relatively serious, and a level-two warning overall crisis decision result is generated. If the overall crisis decision value exceeds the maximum value of the preset range, it indicates that the overall urgency of the situation in the hazardous waste storage area is extremely serious, and a level-three warning overall crisis decision result is generated. Based on the overall crisis decision result, corresponding differentiated linkage disposal instructions are triggered.

[0100] Example 2: Figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the solid hazardous waste temporary storage and collection management method based on a hazardous waste temporary storage room proposed in this invention includes the following steps:

[0101] Step 1: Multi-dimensional perception and data preprocessing:

[0102] Collect multi-dimensional data from the hazardous waste temporary storage room, and output a standardized perception dataset after completing invalid value filtering, outlier marking and format standardization of the raw data.

[0103] Step 2: Dynamic assessment of the safe temporary storage capacity at each storage point:

[0104] The safe temporary storage capacity of solid hazardous waste at each storage site is dynamically and quantitatively calculated to determine the risk of exceeding the storage capacity and output the risk value of exceeding the capacity.

[0105] Step 3: Accurately categorize and classify external hazardous waste upon entry into the warehouse.

[0106] Accurately classify and locate each independent storage point within the temporary storage room for external hazardous waste, and determine the risk of mixed storage at each storage point and calculate the risk value of mixed storage.

[0107] Step 4: Intelligent planning of the hazardous waste collection and evacuation route within the temporary storage room:

[0108] When the hazardous waste stored in the temporary storage room reaches the preset collection conditions, the optimal collection path and standardized execution instructions are generated based on multi-objective optimization planning analysis of the flow path.

[0109] Step 5: Emergency Response Based on Differentiated Levels

[0110] The hazard level of each storage point and the overall space in the temporary storage room is determined separately, and corresponding differentiated linkage and disposal instructions are triggered for different hazard levels.

[0111] The working principle of this invention is as follows: During use, the multi-dimensional sensing module in the temporary storage area achieves accurate collection and standardized processing of all-dimensional data. Based on the dynamic judgment module for temporary storage safety and the precise classification module for solid waste categories, the safe capacity is dynamically calculated and the risk of exceeding the capacity is determined. According to the compatibility standard, the hazardous waste is accurately classified and the hidden dangers of mixed storage are investigated to ensure the compliance of temporary storage. Furthermore, the intelligent planning module for collection routes, combined with multi-objective optimization, generates the optimal path and standardized instructions, improving collection and transportation efficiency and reducing operational risks. In addition, the hazardous situation classification and linkage response module integrates multi-dimensional risk data, quantifies and determines the hazardous situation level of each storage point and the overall situation, and triggers differentiated disposal instructions to avoid improper disposal. This achieves closed-loop management of the entire process of temporary storage of solid hazardous waste. From storage and classification, capacity monitoring to collection and transportation and hazardous situation response, a collaborative mechanism is formed, effectively reducing the environmental risks and safety accident rate during the temporary storage of hazardous waste.
