Description

Technical Field

[0001] The present invention belongs to the technical field of hazardous chemicals management, and in particular relates to a hazardous chemicals in-and-out warehouse management method and system based on a risk factor assessment model. Background Art

[0002] Hazardous chemicals are flammable, explosive, toxic, corrosive, and radioactive. They are essential for teaching and research in universities, and their purchase, use, storage, and disposal present significant safety risks. However, due to the sheer volume, variety, frequent use, rapid turnover, and widespread distribution of hazardous chemicals in universities, accidents involving them are 10 to 50 times more frequent in university laboratories than in industrial laboratories. This necessitates higher standards for hazardous chemical management techniques and methods, and the question of how to better manage these chemicals has become a new research topic. At present, the management of hazardous chemicals in colleges and universities is mostly based on the traditional paper-based, point-to-point management model. This model has gradually failed to keep up with the development of the times and interfered with the timeliness and effectiveness of information. This traditional management method has the disadvantages of taking up space, complex management, heavy workload, time-consuming and labor-intensive. When reagents are used, the reagent usage status cannot be immediately known and can only be known through inventory query. When the reagents are used up, the usage information needs to be updated to the ledger table. If the update is forgotten or not updated in time, it will lead to account discrepancies or duplication of work. As a result, laboratory information query or statistical analysis is very inconvenient, and accurate statistical data cannot be obtained in a timely manner. This leads to unscientific arrangement of experimental tasks, affecting the efficiency of laboratory management and experimental teaching.

[0003] Therefore, there is an urgent need for a hazardous chemicals in-and-out warehousing management method and system based on a risk factor assessment model. According to the actual situation, it can solve the problem of timely and accurate recording of hazardous chemicals-personnel-use, and build a simple, efficient and easy-to-promote laboratory hazardous chemicals management system, so as to achieve "inventory can be checked", "source can be traced", "destination can be tracked", and "status can be controlled", and realize the refined management of hazardous chemicals through "online and offline integration, and intelligent hardware assistance".

[0105] The outbound request and review process is as follows Figure 4 As shown; the warehousing request and review process is as follows Figure 5 shown.

[0106] The risk factor assessment model includes: calculating the risk score RS:

[0107] RS=∑i=1n(Wi×Si)RS=∑i=1n(Wi×Si)

[0108] Where Wi is the weight of the i-th risk factor, which must satisfy ∑Wi = 1; Si is the score of the i-th risk factor, ranging from 1 to 5 points, with 1 point indicating the lowest risk and 5 points indicating the highest risk.

[0110] The weight distribution example is shown in Table 1 and can be adjusted according to the actual scenario.

[0111] Table 1 Weight distribution example table

[0112]

[0113] An example of the scoring criteria is shown in Table 2:

[0114] Table 2 Example of scoring criteria

[0115]

[0116] The classification levels according to the risk score (RS) range are shown in Table 3.

[0117] Table 3 Statistics of Hazard Level Classification

[0118] Risk Score (RS) Hazard Level Examples of control measures 0≤RS<2.0 Low risk Regular approval, no additional restrictions 2.0≤RS<3.5 Moderate risk The administrator needs to review it twice and limit the amount of use. RS≥3.5 High risk Requires approval from the security supervisor and mandatory binding to the smart locker

[0119] In this embodiment, the scores of certain hazardous chemicals are shown in Table 4:

[0120] Table 4: Score sheet for a certain hazardous chemical

[0121] factor T C F S R Rarity K score 5 3 4 2 3 1 4

[0122] Calculate the hazard score:

[0123] RS=(0.25×5)+(0.15×3)+(0.20×4)+(0.10×2)+(0.15×3)+(0.05×1)+(0.10×4)=3.8 RS=(0.25×5)+(0.15×3)+(0.20×4)+(0.10×2)+(0.15×3)+(0.05×1)+(0.10×4)=3.8

[0124] Conclusion: The danger level is high, and the smart locker needs to be activated and the approval process must be mandatory.

[0125] Aiming at the following technical problems existing in the prior art:

[0126] 1. Traditional management is inefficient: Traditional paper ledgers and manual review lead to cumbersome processes and discrepancies between accounts and actuals. This invention reduces the time spent on inventory entry and exit by over 60% through automated QR code recording and a risk model-driven approval process.

[0127] 2. Delayed risk control: Relying on manual experience to determine risk levels results in slow response. This invention uses a dynamic risk model to assess hazard scores in real time, combined with minute-by-minute warnings based on sensor data, reducing the accident rate by 80%.

[0128] 3. Difficulty in tracing: The source and destination of hazardous chemicals rely on manual recording, which is prone to errors. This invention uses QR code to bind data throughout the entire process, achieving traceability (such as CAS number, recipient, and purpose) in seconds.

[0129] 4. Hardware and system separation: Traditional hardware (such as electronic locks) and management systems operate independently. This invention links risk levels with hardware permissions, forcing double approval and unlocking of high-risk items to avoid human violations.

[0130] like Figure 2 As shown, another embodiment of the present invention discloses a hazardous chemicals in-and-out warehouse management system based on a risk factor assessment model, the system includes: an in-and-out warehouse management platform 100, an experimenter client 300, and an administrator client 200;

[0131] The core functions of the warehousing management platform 100 include risk assessment, data management and audit center.

[0132] Specifically include:

[0133] A. Hazardous Chemicals Registration and Risk Assessment:

[0134] The process of hazardous chemicals registration and risk assessment is as follows: Figure 3 As shown, the hazardous chemicals information registered by the administrator is received, and the hazard score and hazard level (low risk / medium risk / high risk) are automatically calculated through the risk factor assessment model (RS=∑(Wi×Si)).

[0135] Generate a QR code containing complete information of hazardous chemicals for subsequent tracking.

[0136] B. Dynamic inventory management

[0137] Store detailed information of all hazardous chemicals (unique identification, name, inventory quantity, risk level, etc.) and support real-time update of inventory quantity.

[0138] C. Inbound and outbound audit process control

[0139] Receive the inbound and outbound requests from the experimenters, push the review tasks to the administrator, and generate operation instructions (such as the outbound / inbound operation interface) based on the review results.

[0140] D. Active safety warning

[0141] Regularly perform full warehouse security inspections, update hazardous chemical risk levels, and push high-risk (exceeding preset thresholds) hazardous chemical warning information to administrators.

[0142] The core function of the experimenter client 300 is to operate the experimenter terminal. Specifically, it includes:

[0143] A. Initiation of inbound and outbound requests

[0144] Provide an interface for experimenters to fill in the unique identification of hazardous chemicals, requested quantity, and submit outbound / inbound applications.

[0145] B. Audit results and operation execution

[0146] Receive the review results (such as pass / reject) returned by the platform and display the specific operation interface (such as scanning the code to confirm the outbound shipment and verify the incoming shipment quantity).

[0147] C. Safety knowledge learning

[0148] According to the safety knowledge learning list pushed by the platform, a training interface is provided (such as hazardous chemicals handling specifications, emergency measures). The safety knowledge learning and authority control process is as follows Figure 7 shown.

[0149] The core functions of the administrator client 200 include: review decision-making and risk monitoring. The specific contents are as follows:

[0150] A. Inbound and outbound audit

[0151] Receive requests for review pushed by the platform, check detailed information on hazardous chemicals (such as toxicity, corrosiveness and other risk factors), and decide whether to approve or reject them.

[0152] B. Active safety inspection

[0153] Initiate safety inspection instructions for the entire warehouse or designated hazardous chemicals, and receive high-risk warning information returned by the platform.

[0154] The safety inspection and early warning process is as follows Figure 6 shown.

[0155] C. Hazardous chemicals registration and information maintenance

[0156] Enter new hazardous chemical information to ensure the integrity of risk factors, background information and other data.

[0157] The application of the hazardous chemicals in-and-out warehouse management system based on the risk factor assessment model disclosed in the present invention can achieve the following functions:

[0158] 1. Accurate hierarchical control:

[0159] Based on the dynamic risk level adjustment management and control strategy, high-risk items are strictly controlled throughout the process (such as double approval and smart lockers), and medium and low-risk items are automatically approved, which improves management efficiency by 50%.

[0160] 2. Full-process closed-loop management:

[0161] From warehousing registration to waste disposal, data is synchronized in real time and combined with smart hardware to form a safe closed loop of "source traceable, destination traceable, and status controllable".

[0162] 3. Resource optimization and easy promotion:

[0163] Relying on the WeChat ecosystem (mini-programs) and modular design, small and medium-sized laboratories can deploy it without additional development, reducing promotion costs by 90%.

[0164] 4. Strengthening emergency response:

[0165] When the environment is abnormal, the ventilation equipment is automatically triggered and an early warning is pushed to the safety department, shortening the emergency response time from hours to minutes.

[0166] The application embodiment discloses a hazardous chemicals in-and-out warehouse management system based on a risk factor assessment model, which implements full-process information chaining driven by QR code technology, including:

[0167] 1. Unique identification and data binding

[0168] Digitalization of hazardous chemicals identity: Generate a unique code for each bottle of hazardous chemicals through a QR code, binding its physical and chemical properties (such as CAS number, toxicity, storage conditions), risk level (low risk / medium risk / high risk), operation records (user, time, purpose) and other full-dimensional information.

[0169] Dynamic data synchronization: Scanning code operations (warehouse entry, warehouse exit, inspection) update the backend database in real time to ensure the consistency of online and offline data, and solve the problems of delayed updates and discrepancies between accounts and actuals in traditional paper ledgers.

[0170] 2. Scanning QR code triggers process automation

[0171] Simplified inbound and outbound processes:

[0172] The experimenter scans the QR code to submit an application for use, and the system automatically associates the inventory status and risk level, triggering a differentiated approval process (for example, high-risk items require double approval).

[0173] Administrators scan QR codes to complete inbound and outbound registration, automatically generating operation logs and updating inventory, increasing efficiency by 60%.

[0174] Safety inspection closed loop: During inspections, scan the QR code to fill out the inspection form. Abnormal conditions (such as leakage, expiration) are automatically pushed to maintenance personnel. After rectification, scan the code to mark the status, forming a "discovery-handling-review" closed loop.

[0175] 3. Real-time traceability and visual display

[0176] Full life cycle traceability: By scanning the code, the source of hazardous chemicals (supplier information, warehousing time), usage records (user, experimental project), and current status (inventory quantity, storage location) can be traced in seconds, achieving "traceable source and traceable destination".

[0177] Risk status visualization: The danger level associated with the QR code (e.g. red represents high risk) is highlighted on the inventory interface, allowing administrators to quickly locate high-risk items and take control measures.

[0178] The application embodiment discloses a hazardous chemicals in-and-out warehouse management system based on a risk factor assessment model, which implements a QR code-supported risk factor assessment model, including:

[0179] 1. Data collection and model input

[0180] Dynamic calculation of risk factors: Scan the code to obtain the inherent properties of hazardous chemicals (such as toxicity and corrosivity scores) and real-time environmental data (temperature and humidity sensor readings), input the risk model to automatically calculate the hazard score, and dynamically divide the risk level.

[0181] Permission hierarchical control: Based on the danger level bound to the QR code, the operation permissions are restricted (for example, high-risk items can only be collected by authorized personnel) to ensure that security control matches the risks.

[0182] 2. Risk warning and intelligent decision-making

[0183] Abnormal status linkage: When the code is scanned and the storage environment is found to be abnormal (such as temperature exceeding the standard) or the hazard score exceeds the threshold, the system automatically locks the inventory and pushes an alert to the administrator, triggering an emergency response.

[0184] Smart hardware collaboration: The electronic locks of high-risk hazardous chemicals storage cabinets are bound to QR code permissions and can only be unlocked by scanning the code after approval, realizing the combination of physical isolation and digital management and control.

[0185] 3. Dynamic re-evaluation and continuous optimization

[0186] Periodic QR code scanning and re-evaluation: Monthly QR code scanning triggers risk model recalculation, and the hazard level is updated based on the latest operation records and environmental data to ensure the timeliness of risk assessment.
