Description

Technical Field

[0001] This invention relates to the field of laboratory management technology, and in particular to a method and system for managing the usage of hazardous chemicals in laboratories. Background Technology

[0002] Hazardous chemicals are a shorthand for dangerous chemicals, referring to chemicals that possess hazardous properties such as flammability, explosiveness, toxicity, corrosiveness, and radioactivity during production, storage, transportation, and use. Improper management or handling can cause significant harm to human health, the environment, and property. Therefore, the management and use of hazardous chemicals require special attention and must adhere to relevant safety regulations and standards. The use of hazardous chemicals in laboratories is unavoidable, as many experiments require chemical reagents and raw materials. However, because laboratories are typically small environments with relatively compact equipment and facilities, the management and use of hazardous chemicals are particularly important. Even slight negligence can lead to accidents, endangering personnel safety and the smooth progress of experiments. Improper dosage of hazardous chemicals during experiments can easily lead to accidents, and in severe cases, cause injury to laboratory personnel.

[0003] Therefore, the present invention provides a method and system for managing the usage of hazardous chemicals in laboratories. Summary of the Invention

[0037] In the real-time experimental behavior, locate the hazardous chemical corresponding to the experimental violation, and deduce the violation consequences based on the material data of the hazardous chemical corresponding to the experimental violation.

[0038] Based on the consequences of the violation, remedial measures are constructed and transmitted to the display terminal of the laboratory for display, and simultaneously transmitted to the early warning terminal of the laboratory for early warning.

[0042] Step 42: Screen target hazardous chemicals whose real-time remaining quantity is lower than the corresponding amount to be tested, and find the undue hazard corresponding to each target hazardous chemical in the MSDS;

[0043] Step 43: Based on the aforementioned undue hazards, construct a hazard warning for the current experimental project and restrict the experimental personnel from using the target hazardous chemical for the current experimental project;

[0044] Step 44: Generate an alarm text based on the aforementioned inappropriate hazard and transmit it to the laboratory's early warning terminal for early warning.

[0045] This invention provides a hazardous chemical usage management system for a laboratory, comprising:

[0050] In one feasible approach

[0051] The material analysis module includes:

[0052] The element analysis unit is used to perform structured decomposition of the current experimental project to obtain several sub-project elements, construct the element logic tree of the current experimental project according to the element relationships between different sub-project elements, identify several tree branches contained in the element logic tree, and construct the experimental process of the current experimental project according to the tree branches.

[0053] The planning and construction unit is used to construct the process progress corresponding to each experimental process, assign corresponding element operation attributes to the corresponding sub-project elements of the process progress, filter the first sub-project elements belonging to the material attribute, and filter the first sub-project elements belonging to the operation attribute, and construct the material demand plan corresponding to the experimental process based on the first sub-project elements and the second sub-project elements.

[0061] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0062] Example 1

[0063] This embodiment provides a method for managing the usage of hazardous chemicals in a laboratory, such as... Figure 1 As shown, it includes:

[0064] Step 1: Decompose the current experimental project in the laboratory into a process, obtain the material requirement plan corresponding to each experimental process, and search for the material data corresponding to each hazardous chemical in the MSDS.

[0065] Step 2: Based on the material demand plan and the material data, determine the usage quantity and usage period for each hazardous chemical, and construct the hazardous chemical management rules for the laboratory;

[0066] Step 3: Use the hazardous chemicals management rules to supervise and manage the current experimental project in real time, and take inventory of the real-time remaining quantity of each hazardous chemical after the completion of the previous experimental project;

[0067] Step 4: Locate the target hazardous chemical with an abnormal real-time remaining quantity, restrict the laboratory personnel from using the target hazardous chemical, and trigger a laboratory alarm.

[0068] In this example, the current experimental project refers to the experimental project that the laboratory is currently conducting;

[0069] In this example, the experimental procedure represents the process that needs to be executed to carry out the current experimental project;

[0070] In this example, MSDS stands for Material Safety Data Sheet, which contains various important data about hazardous chemicals;

[0071] In this example, the material requirements plan represents a table of material statistics needed to execute an experimental procedure;

[0072] In this example, a time period is used to represent the time period during which the hazardous chemicals were retrieved;

[0073] In this example, the hazardous chemicals management rules refer to the rules that must be followed when handling and using hazardous chemicals in the laboratory.

[0074] In this example, the target hazardous chemical indicates that the remaining quantity is insufficient to continue supporting the smooth progress of the current experimental project.

[0075] The working principle and beneficial effects of the above technical solution are as follows: Since different experimental projects use different materials, the process is decomposed before the experimenters begin the current experimental project. This determines the material requirement plan corresponding to each experimental process and retrieves the material data for each hazardous chemical, facilitating subsequent management of hazardous chemical usage. Then, based on the material requirement plan and material data, the usage amount and time period for each hazardous chemical are deduced, thereby constructing corresponding hazardous chemical management rules. This allows for real-time supervision and management of the experimenters' operations. By analyzing the real-time remaining amount of different hazardous chemicals after completing the previous experimental project, it is determined whether the hazardous chemicals in the laboratory can meet the needs of the current experimental project, and corresponding alarm reminders are issued. In this way, the usage of hazardous chemicals in the laboratory can be predicted in advance, and the experimental process can be monitored to avoid insufficient or excessive use of hazardous chemicals. This effectively improves the safety level of the laboratory, reduces laboratory accidents caused by inaccurate usage, and ensures the smooth progress of experimental projects.

[0076] Example 2

[0077] Based on Example 1, the method for managing the usage of hazardous chemicals in a laboratory further includes:

[0078] The MSDS is inventoried within a specified period to screen out expired laboratory materials.

[0079] The expired laboratory materials are temporarily stored and disposed of, and the laboratory personnel are restricted from using the expired laboratory materials.

[0080] In this example, the specified period is 14 days.

[0081] The working principle and beneficial effects of the above technical solution are as follows: Since expired hazardous chemicals are more dangerous, it is necessary to regularly check the expiration dates of materials in the laboratory and dispose of expired laboratory materials. In order to further prevent accidents, the use of expired laboratory materials by laboratory personnel is restricted, thus ensuring the personal safety of laboratory personnel.

[0082] Example 3

[0083] Based on Example 1, the method for managing the usage of hazardous chemicals in a laboratory, step 1 includes:

[0084] Step 11: Perform a structured decomposition of the current experimental project to obtain several sub-project elements, construct an element logic tree of the current experimental project based on the element relationships between different sub-project elements, identify several tree branches contained in the element logic tree, and construct the experimental process of the current experimental project based on the tree branches;

[0085] Step 12: Construct the process progress corresponding to each experimental process, assign corresponding element operation attributes to the sub-item elements corresponding to the process progress, filter the first sub-item elements belonging to the material attribute, and filter the first sub-item elements belonging to the operation attribute, and construct the material demand plan corresponding to the experimental process based on the first sub-item elements and the second sub-item elements.

[0086] Step 13: Obtain the MSDS of the laboratory, search for each of the first sub-item elements in the MSDS, determine the number of hazardous chemicals used in each experimental procedure based on the search results, perform a deep search for each hazardous chemical in the MSDS, and obtain the material data corresponding to each hazardous chemical.

[0087] In this example, the sub-project element represents the elements needed to carry out the project within the current experimental project, including: materials, experimental operations, etc.

[0088] In this example, the element logic tree represents a logic tree constructed based on the element relationships between different sub-item elements;

[0089] In this example, tree branches represent independent branches contained in the element logic tree, and one tree branch corresponds to one experimental process;

[0090] In this example, process progress represents the progress required to complete an experimental process;

[0091] In this example, the element operation attribute indicates the operation that needs to be performed on a sub-item element;

[0092] In this example, the material attribute indicates that the sub-item element belongs to laboratory materials, and the operation attribute indicates that the sub-item element belongs to experimental operations.

[0093] The working principle and beneficial effects of the above technical solution are as follows: In order to better supervise the experimental process, the current experimental project is first divided into several sub-project elements. Then, the logical relationship between different sub-project elements is analyzed to construct an element logic tree. Then, the experimental process of the current experimental project is determined according to the tree branches contained in the element logic tree. Then, according to the progress of the experimental process, each sub-project element is assigned corresponding attributes, and a material requirement plan for the experimental process is constructed, laying the foundation for subsequent material management. Then, each sub-project element is searched in the laboratory's MSDS to determine several types of hazardous chemicals required for the experimental process. At the same time, a deep search is performed on the hazardous chemicals in the MSDS to determine the material data of each hazardous chemical. In this way, comprehensive supervision of hazardous chemicals can be carried out to ensure the smooth progress of the experiment and the personal safety of the experimental personnel.

[0094] Example 4

[0095] Based on implementation 3, the method for managing the usage of hazardous chemicals in a laboratory, which constructs a material requirements plan corresponding to the experimental process based on the first sub-project element and the second sub-project element, includes:

[0096] In the process progress, each of the first sub-project elements is marked with a first mark, and each of the second sub-project elements is marked with a second mark.

[0097] Based on the marking results, determine several material usage procedures corresponding to the experimental process, and identify the laboratory materials included in each material usage procedure.

[0098] Based on the material usage procedures, the usage of the corresponding laboratory materials is estimated, and a material requirement plan for the experimental process is generated.

[0099] In this example, the first and second markers represent the results of distinguishing and marking the first and second sub-item elements in the process progress.

[0100] In this example, the material usage procedure indicates the order and method of using different laboratory materials.

[0101] The working principle and beneficial effects of the above technical solution are as follows: By marking the first and second sub-project elements in the process progress, the material usage procedures of the experimental process are determined. Then, the usage of laboratory materials included in each material usage procedure is estimated, and a material demand plan for the experimental process is generated. In this way, multiple first and second sub-project elements can be processed in a short time to determine the laboratory materials used in different experimental processes, thereby improving the accuracy of subsequent usage monitoring.

[0102] Example 5

[0103] Based on Example 1, the method for managing the usage of hazardous chemicals in a laboratory, step 2 includes:

[0104] Step 21: Construct the hazardous chemical requisition procedure corresponding to each experimental process according to the material demand plan and the material data. Adjust the timing of the hazardous chemical requisition procedure according to the process sequence of each experimental process in the current experimental project to generate the total hazardous chemical requisition procedure for the current experimental project.

[0105] Step 22: Based on the material demand plan, determine several call times and call quantities corresponding to each hazardous chemical, map the call quantities corresponding to each hazardous chemical to the corresponding process time periods in the total hazardous chemical call process, and adjust the hazardous chemical usage in the process time periods.

[0106] Step 23: Determine the usage amount and usage time period for each hazardous chemical based on the adjusted total hazardous chemical requisition process, create a hazardous chemical usage model for the laboratory, and run the hazardous chemical usage model to analyze the probability of collision risk between different hazardous chemicals using the corresponding material data;

[0107] Step 24: Adjust the time period of the total hazardous chemical requisition process according to the collision risk probability, and construct the hazardous chemical management rules of the laboratory based on the adjusted total hazardous chemical requisition process.

[0108] In this example, the hazardous chemical retrieval procedure refers to the procedure that needs to be performed when taking different hazardous chemicals during a test process.

[0109] The working principle and beneficial effects of the above technical solution are as follows: By constructing the hazardous chemical requisition procedure corresponding to each experimental process, the total hazardous chemical requisition procedure for the current experimental project is generated. Then, the amount of hazardous chemicals used in each time period of the total hazardous chemical requisition procedure is adjusted according to the material demand plan. Furthermore, by creating a model, the probability of collision risk between different hazardous chemicals is analyzed, and the time period of the total hazardous chemical requisition procedure is adjusted. This effectively avoids the phenomenon of collision accidents when experimental personnel take different hazardous chemicals at the same time. Finally, based on the adjusted total hazardous chemical requisition procedure, the laboratory's hazardous chemical management rules are constructed. These rules can be used to supervise and manage the experimental process of experimental personnel, thereby improving the safety of the laboratory.

[0110] Example 6

[0111] Based on Example 1, the method for managing the usage of hazardous chemicals in a laboratory, step 3 includes:

[0112] Step 31: Collect the real-time experimental behavior of the experimenters in the laboratory, construct the real-time standardized behavior of the experimenters using the hazardous chemicals management rules, evaluate the real-time experimental behavior using the real-time standardized behavior, and obtain effective behavioral information of the experimenters.

[0113] Step 32: Based on the valid behavioral information, determine the real-time use of hazardous chemicals by the experimenters. After the previous experiment is completed, analyze the real-time usage of the hazardous chemicals and determine and display the real-time remaining quantity of each hazardous chemical.

[0114] In this example, real-time experimental behavior refers to the behavior of the experimenters when conducting experiments in the laboratory.

[0115] In this example, real-time normative behavior refers to the normative behavior that the experimenter should exhibit at the current moment;

[0116] In this example, the valid behavioral information represents the actions that must be performed to execute the current experimental project;

[0117] In this example, the real-time usage represents the amount of various hazardous chemicals used during the previous experimental project.

[0118] The working principle and beneficial effects of the above technical solution are as follows: By evaluating the real-time experimental behavior of experimental personnel using hazardous chemical management rules, effective information on the behavior of experimental personnel is obtained, thereby determining the real-time use of hazardous chemicals by experimental personnel. After the completion of an experimental project, the real-time remaining quantity of each hazardous chemical is determined and displayed. This allows experimental personnel to understand the remaining quantity of hazardous chemicals at any time and makes it easier to determine whether the remaining quantity of hazardous chemicals can meet the usage of the next experimental project.

[0119] Example 7

[0120] Based on Example 6, the method for managing the use of hazardous chemicals in a laboratory further includes:

[0121] Based on the hazardous chemicals management rules, filter the valid information on behaviors to identify experimental violations;

[0122] In the real-time experimental behavior, locate the hazardous chemical corresponding to the experimental violation, and deduce the violation consequences based on the material data of the hazardous chemical corresponding to the experimental violation.

[0123] Based on the consequences of the violation, remedial measures are constructed and transmitted to the display terminal of the laboratory for display, and simultaneously transmitted to the early warning terminal of the laboratory for early warning.

[0124] In this example, "behavioral hazardous chemicals" refers to the hazardous chemicals affected by the experimental violation.

[0125] The working principle and beneficial effects of the above technical solution are as follows: Hazardous chemical management rules are used to identify experimental violations by laboratory personnel. Consequence analysis of these violations is then conducted on the hazardous chemicals involved, and corresponding remedial measures are developed to remind laboratory personnel to address errors promptly and prevent the spread of danger. Simultaneously, an early warning system is used to alert all laboratory personnel to safety precautions, effectively reducing the probability of dangerous accidents occurring in the laboratory.

[0126] Example 8

[0127] Based on Example 1, the method for managing the usage of hazardous chemicals in a laboratory, step 4 includes:

[0128] Step 41: Determine a number of hazardous chemicals to be tested for the current experimental project, and the amount of each hazardous chemical to be tested, based on the material demand plan.

[0129] Step 42: Screen target hazardous chemicals whose real-time remaining quantity is lower than the corresponding amount to be tested, and find the undue hazard corresponding to each target hazardous chemical in the MSDS;

[0130] Step 43: Based on the aforementioned undue hazards, construct a hazard warning for the current experimental project and restrict the experimental personnel from using the target hazardous chemical for the current experimental project;

[0131] Step 44: Generate an alarm text based on the aforementioned inappropriate hazard and transmit it to the laboratory's early warning terminal for early warning.

[0132] The working principle and beneficial effects of the above technical solution are as follows: By using the material demand plan to determine the amount of each hazardous chemical to be tested in the current experimental project, the target hazardous chemical with insufficient remaining quantity is determined. Then, the adverse hazards of the target hazardous chemical are deduced and corresponding reminders are generated. At the same time, in order to ensure the safety of the experimental personnel, the use of the target hazardous chemical by the experimental personnel is restricted, and early warning reminders are given to avoid the experiment failing halfway through.

[0133] Example 9

[0134] This embodiment provides a hazardous chemical usage management system for a laboratory, such as... Figure 2 As shown, it includes:

[0135] The materials analysis module is used to decompose the current experimental projects in the laboratory, obtain the material demand plan corresponding to each experimental process, and search for the material data corresponding to each hazardous chemical in the MSDS.

[0136] The rule building module is used to determine the usage amount and usage period of each hazardous chemical based on the material demand plan and the material data, and to build the hazardous chemical management rules of the laboratory.

[0137] The real-time inventory module is used to supervise and manage the current experimental project in real time using the hazardous chemical management rules, and to count the real-time remaining quantity of each hazardous chemical after the completion of the previous experimental project.

[0138] The hazard alarm module is used to locate target hazardous chemicals with abnormal real-time remaining quantities, restrict laboratory personnel from using the target hazardous chemicals, and trigger laboratory alarms.

[0139] In this example, the current experimental project refers to the experimental project that the laboratory is currently conducting;

[0140] In this example, the experimental procedure represents the process that needs to be executed to carry out the current experimental project;

[0141] In this example, MSDS stands for Material Safety Data Sheet, which contains various important data about hazardous chemicals;

[0142] In this example, the material requirements plan represents a table of material statistics needed to execute an experimental procedure;

[0143] In this example, a time period is used to represent the time period during which the hazardous chemicals were retrieved;

[0144] In this example, the hazardous chemicals management rules refer to the rules that must be followed when handling and using hazardous chemicals in the laboratory.

[0145] In this example, the target hazardous chemical indicates that the remaining quantity is insufficient to continue supporting the smooth progress of the current experimental project.

[0146] The working principle and beneficial effects of the above technical solution are as follows: Since different experimental projects use different materials, the process is decomposed before the experimenters begin the current experimental project. This determines the material requirement plan corresponding to each experimental process and retrieves the material data for each hazardous chemical, facilitating subsequent management of hazardous chemical usage. Then, based on the material requirement plan and material data, the usage amount and time period for each hazardous chemical are deduced, thereby constructing corresponding hazardous chemical management rules. This allows for real-time supervision and management of the experimenters' operations. By analyzing the real-time remaining amount of different hazardous chemicals after completing the previous experimental project, it is determined whether the hazardous chemicals in the laboratory can meet the needs of the current experimental project, and corresponding alarm reminders are issued. In this way, the usage of hazardous chemicals in the laboratory can be predicted in advance, and the experimental process can be monitored to avoid insufficient or excessive use of hazardous chemicals. This effectively improves the safety level of the laboratory, reduces laboratory accidents caused by inaccurate usage, and ensures the smooth progress of experimental projects.

[0147] Example 10

[0148] Based on Example 9, the hazardous chemical usage management system for a laboratory, wherein the material analysis module includes:

[0149] The element analysis unit is used to perform structured decomposition of the current experimental project to obtain several sub-project elements, construct the element logic tree of the current experimental project according to the element relationships between different sub-project elements, identify several tree branches contained in the element logic tree, and construct the experimental process of the current experimental project according to the tree branches.

[0150] The planning and construction unit is used to construct the process progress corresponding to each experimental process, assign corresponding element operation attributes to the corresponding sub-project elements of the process progress, filter the first sub-project elements belonging to the material attribute, and filter the first sub-project elements belonging to the operation attribute, and construct the material demand plan corresponding to the experimental process based on the first sub-project elements and the second sub-project elements.

[0151] The hazardous chemicals management unit is used to obtain the MSDS of the laboratory, search for each of the first sub-item elements in the MSDS, determine several types of hazardous chemicals used in each experimental procedure based on the search results, and perform a deep search in the MSDS for each hazardous chemical to obtain the material data corresponding to each hazardous chemical.

[0152] In this example, the sub-project element represents the elements needed to carry out the project within the current experimental project, including: materials, experimental operations, etc.

[0153] In this example, the element logic tree represents a logic tree constructed based on the element relationships between different sub-item elements;

[0157] In this example, the material attribute indicates that the sub-item element belongs to laboratory materials, and the operation attribute indicates that the sub-item element belongs to experimental operations.

[0158] The working principle and beneficial effects of the above technical solution are as follows: In order to better supervise the experimental process, the current experimental project is first divided into several sub-project elements. Then, the logical relationship between different sub-project elements is analyzed to construct an element logic tree. Then, the experimental process of the current experimental project is determined according to the tree branches contained in the element logic tree. Then, according to the progress of the experimental process, each sub-project element is assigned corresponding attributes, and a material requirement plan for the experimental process is constructed, laying the foundation for subsequent material management. Then, each sub-project element is searched in the laboratory's MSDS to determine several types of hazardous chemicals required for the experimental process. At the same time, a deep search is performed on the hazardous chemicals in the MSDS to determine the material data of each hazardous chemical.
