Description

Technical Field

[0001] The present invention relates to the technical field of process management systems, and in particular to a hazardous chemicals process management system. Background Art

[0002] Hazardous chemicals, referred to as hazardous chemicals, refer to highly toxic chemicals and other chemicals that have properties such as poison, corrosion, explosion, combustion, and combustion-supporting, and are harmful to the human body, facilities, and the environment. For example, sulfuric acid, hydrofluoric acid, and other chemicals used in the preparation of ultra-pure quartz sand. At present, the placement and storage of hazardous chemicals are stored at designated locations in accordance with relevant national laws and regulations. In actual industrial production, the usual process of hazardous chemicals is for production personnel to issue a receipt, and after review and approval by production management personnel, they are collected from the warehouse. Usually, for the convenience of use, front-line staff often over-collect or collect some hazardous chemicals in advance and store them in the production workshop, which creates safety hazards. Moreover, the personnel who collect materials are usually idle personnel arranged according to production. Some of these personnel only have limited basic chemical knowledge and cannot fully respond to various unexpected situations during the operation of hazardous chemicals. Therefore, it is of great significance to enhance the process control of hazardous chemicals in production and use.

[0003] The existing hazardous chemicals management system can refer to the Chinese invention patent application document with publication number CN 117952510 A, which discloses a hazardous chemicals management system, including: a registration module: used to determine the target hazardous chemicals to be used according to the acquired material demand plan, and complete the hazardous chemicals ledger registration in combination with MSDS; a use module: used to apply for the use of the target hazardous chemicals that need to be approved, and then register the use of all target hazardous chemicals to generate a use registration form; an inventory posting module: used for physical inventory, and obtain an inventory difference list based on the hazardous chemicals inventory list, and realize automatic posting of inventory differences; a scrapping processing module: used to obtain a list of expired or invalid hazardous chemicals, and then after scrapping application and review, waste treatment is carried out while automatically updating the hazardous chemicals ledger; a query module: used to realize quick query and browsing of MSDS content based on the main information of hazardous chemicals.

[0004] The above-mentioned hazardous chemicals management system only performs statistical management on the inventory and entry and exit of hazardous chemicals, and cannot accurately manage and monitor process factors such as the amount of hazardous chemicals taken, the time of taking, and the person who takes them, thereby failing to achieve process control of production taking. Summary of the invention

[0005] The purpose of the present invention is to provide a hazardous chemicals process management system, which realizes the coordinated cooperation of production, manpower, management and warehousing, and can effectively control the process of application and use of hazardous chemicals.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: A hazardous chemicals process management system, including a production management module, a material storage module, a personnel information module, a management decision module, a voucher data terminal and a verification terminal;

[0007] The production management module is used to input the production plan and generate a time-series material list according to the production plan, wherein the time-series material list includes the material type and the corresponding collection time and collection quantity;

[0008] The material storage module is used to store the material information of the materials in the warehouse, as well as the in-warehouse and out-warehouse information of the materials;

[0009] The personnel information module is used to store the material manager's biometric information, including fingerprint information, iris information, and three-dimensional facial data, and is used to mark the material manager's information;

[0010] The management decision module is used to:

[0011] The information of the material storage module is called according to the time-series material list. When the inventory of the corresponding material is higher than the set value, the material requisition information is generated.

[0012] Read the on-the-job material manager information in the personnel information module, and randomly select an on-the-job material manager to set as the receiving clerk.

[0013] Generate an electronic public key and an electronic private key through logical encryption according to the material collection information and the collection staff information, send the electronic private key to the voucher data terminal of the corresponding collection staff, and send the electronic public key to the verification terminal;

[0014] The credential data terminal is used to receive and output the electronic private key sent by the management decision module;

[0015] The verification end is used to read the electronic private key information and collect the biometric information of the recipient, match the electronic private key and the electronic public key and verify the biometric information of the recipient. When the electronic private key, the electronic public key and the biometric information are consistent, a warehouse outbound list is generated and sent to the material storage module.

[0016] Through the above technical solution, when the hazardous chemicals process management system is applied, the permissions of each module can be set in different parts. For example, the production management module is controlled by the production management personnel. According to the order production tasks, the production plan is input, and then the production management module intelligently generates a time-series material list. The materials are collected according to the information on the time-series material list, which can well meet the production needs, and at the same time will not cause the accumulation and storage of hazardous chemicals on the front line, thereby reducing safety hazards; the material storage module is usually under the responsibility of the warehousing department, and through inventory verification, it stores the accurate inventory information of various hazardous chemicals; the personnel information module is usually under the responsibility of the human resources department, which stores the personal information of employees, and can also conveniently update the on-the-job material management information in real time through attendance. The information of the material manager is stored in the computer. By dispersing data, the security level of information is improved, making the process of hazardous chemicals collection and use more controllable. The collectors are randomly selected, and the material collection information and the collector information are logically encrypted to generate an electronic public key and an electronic private key, and the electronic private key is sent to the credential data end of the corresponding collector. In this way, the collection of hazardous chemicals by each material manager is a random event, which cannot be known or predicted by other people. Only the collector temporarily knows the collection task, which greatly ensures information security. The task-based collector is directly responsible to the data center, with flat management, which is easy to trace and manage. The hazardous chemicals process management system realizes the coordinated cooperation of production, manpower, management, and warehousing, and can well control the process of application and use of hazardous chemicals.

[0017] Preferably, the management decision module includes a processing unit and an encryption unit;

[0018] The processing unit is used to parse the time series material list to obtain the security level, material category, and quantity information of the materials to be collected, randomly screen the information of the on-the-job material managers according to the security level, material category, and quantity information of the materials, determine the collector, and output verification information;

[0019] The encryption unit performs asymmetric logic encryption on the verification information output by the processing unit to generate an electronic public key and an electronic private key.

[0020] Through the above technical solution, the processing unit parses the time-series material list to obtain information such as the material's safety level, material category, and quantity of use, and then uses this information as a factor to screen the information of on-the-job material managers, so that the selected users have the ability to complete the current hazardous chemical use tasks well. In addition, the encryption unit encrypts the information through an asymmetric logic encryption method, thereby further improving the security and reliability of the information.

[0021] Preferably, the credential data terminal includes an identity authentication unit, a key compiler and an interaction unit;

[0022] The identity verification unit is used to collect and verify the identity information of the login user, and when it meets the set value, it is linked to the interaction unit;

[0023] The key compiler is used to compile the received electronic private key and output it in the form of an electronic certificate, and the output form includes a QR code and a barcode;

[0024] The interaction unit is used to output the electronic certificate output by the key compiler, as well as input and output other information.

[0025] Through the above technical solution, the registrant enters verification information through the identity authentication unit, and then links to the interaction unit after verification, so as to obtain the received electronic certificate and other interactive information; the electronic certificate is output in the form of QR code, barcode, etc., so that the information can be efficiently transmitted and output.

[0026] Preferably, the credential data end also includes an assessment unit, which is connected to a hazardous chemicals knowledge database. The assessment unit randomly calls the data in the hazardous chemicals knowledge database according to the set timeline nodes and the identity information of the current logon user, generates assessment information, and sends it to the interaction unit; the assessment unit evaluates the assessment items returned by the logon user through the interaction unit, rates the current logon user according to the evaluation results, and sends the rating information to the personnel information module, which performs rating marking.

[0027] Through the above technical solution, by setting up an assessment unit, the credential data end regularly sends assessment information to the material manager through the interactive unit. The material manager submits the answer after completing the interactive unit, and then the assessment unit conducts an assessment. The assessment information is generated based on the identity information of the current logon user, and data is randomly called from the hazardous chemicals knowledge database. This randomness increases the unpredictability of the assessment and improves the authenticity and effectiveness of the assessment. The assessment information rates the current logon user based on the assessment results, and sends the rating information to the personnel information module, which marks the rating, so that the human resources department or other management departments can clearly and timely understand the hazardous chemicals knowledge level of each material manager, facilitate the adjustment of their work content, and transfer unqualified material managers or enhance their learning, thereby ensuring the safety and reliability of hazardous chemicals circulation management.

[0028] Preferably, the encryption unit includes an editable logic processor, an instruction set and a random function compiler;

[0029] The editable logic processor executes and calls instructions in the instruction set according to the information input type, and configures encryption parameters, including encryption algorithm, key length, and padding scheme;

[0030] The random function compiler generates a random function, and generates a random number sequence through the random function;

[0031] The editable logic processor calls the random numbers in the random number sequence according to the encryption algorithm to generate an electronic public key and an electronic private key.

[0032] Through the above technical solution, the editable logic processor can execute and call the instructions in the instruction set according to the type of information input, and configure encryption parameters such as encryption algorithm, key length and padding scheme. This flexibility allows the system to adjust the encryption strategy according to different security requirements and policies. Through the random number sequence generated by the random function compiler, the editable logic processor can generate more complex and unpredictable keys, which greatly increases the security of the encryption key. The random number sequence generated by the random function compiler helps prevent attacks on encryption keys, such as differential attacks and linear attacks. Hazardous chemicals process management systems need to adapt to changing security threats and compliance requirements, so the high configurability of the encryption unit is crucial. This design allows the system to quickly adapt to new security challenges without replacing the entire encryption module. The encryption unit is designed to be modular and easy to integrate into existing systems and maintain and upgrade when necessary.

[0033] Preferably, the set-up of the receiver includes the following steps:

[0034] S1, read all on-the-job material managers’ information, R = {r1, r2, ..., r n}, where r i Represents the information of the i-th on-the-job material manager;

[0035] S2, filter valid administrators, filter material administrators who meet the authority requirements according to the material security level, material category and requisition quantity in the material requisition information, F = {f1, f2, ..., f n}, where f i Represents the information of the i-th valid administrator;

[0036] S3, randomly select the user S, S = random_slect (F),

[0037] random_select(F) is a random function, which includes the following logical steps:

[0038] 1) Determine whether F is a non-empty list; when F is a non-empty list, obtain all subsets of F;

[0039] 2) Use a random number generator to generate a random index ranging from 0 to the length of the F list minus 1;

[0040] 3) According to the generated random index, select the corresponding material manager from the F list.

[0041] Through the above technical solution, when setting up the material collection staff, the information of all on-duty material managers is first collected indiscriminately, and then the material managers who meet the authority requirements are screened through the material safety level, material category and collection quantity in the material collection information, thereby ensuring the comprehensiveness of the information. For valid administrators who meet the conditions, a random function is used for selection, thereby ensuring fairness and security.

[0042] Preferably, the verification end includes a credential collector, a fingerprint recognition unit, a pupil recognition unit, a facial recognition unit, and an analysis and judgment unit;

[0043] The voucher collector is used to collect and compile the electronic voucher output by the voucher data terminal and send it to the analysis and judgment unit;

[0044] The fingerprint recognition unit is used to collect fingerprint data and send it to the analysis and judgment unit;

[0045] The pupil recognition unit is used to collect iris data and send it to the analysis and judgment unit;

[0046] The facial recognition unit is used to collect facial three-dimensional data and send it to the analysis and judgment unit;

[0047] The analysis and judgment unit verifies the identity of the visitor based on the electronic credential and any one or more of the fingerprint data, iris data, and facial three-dimensional data. When the electronic private key, the electronic public key, and the biometric information are consistent, a warehouse outbound list is generated and sent to the material storage module, and an access log is generated.

[0048] Through the above technical solution, in addition to setting up a credential collector to collect electronic credentials output by the credential data end, the verification end can also collect biometric information of visitors through fingerprints, pupils, facial recognition and other forms, and then verify and judge the identity of the visitor based on the electronic credentials and any one or more of the fingerprint data, iris data, and facial three-dimensional data through the analysis and judgment unit, thereby effectively ensuring the accuracy and security of the school team verification, and having good adaptability to different visitors.

[0049] Preferably, the material storage module includes an electronic tag, a data reading and writing unit, an in-stock information unit, an incoming stock information unit, and an out-of-stock information unit;

[0050] The electronic tag is set on the material container and is used to store and record the production and circulation information of the material; the data reading and writing unit is used to read the stored information in the electronic tag or write the new information into the electronic tag; the in-stock information unit is used to dynamically update the stored in-stock material information according to the material's in-stock and out-stock information; the incoming information unit is used to form an incoming ledger according to the incoming information read by the data reading and writing unit; the out-of-stock information unit is used to form an out-of-stock ledger according to the out-of-stock information read by the data reading and writing unit.

[0051] Through the above technical solution, by setting electronic tags on material containers, it is convenient to record the production and circulation information of materials, and the warehouse entry and exit records can be conveniently and quickly viewed and managed through the warehouse entry and exit ledgers; the material storage module, by integrating electronic tags, data reading and writing units, in-stock information units, entry information units and exit information units, realizes the electronic and information management process of materials in the circulation process, which is convenient for staff to manage, monitor and trace hazardous chemicals in the circulation process.

[0052] Preferably, the facial recognition unit includes a long-range camera and at least two short-range cameras; when the person being collected is within a set area,

[0053] The long-range camera can cover the whole body of the subject and can select the facial area of ​​the subject;

[0054] The acquisition range of the close-range camera can cover at least 2 / 3 of the facial area of ​​the subject, and the collection of images acquired by the close-range camera can cover the entire facial area of ​​the subject.

[0055] Through the above technical scheme, by setting up a long-range camera, when a visitor walks into the set area, the visitor can be quickly identified, and then the facial recognition unit can be awakened to work, and the visitor's overall facial three-dimensional contour is collected by the long-range camera for rapid modeling. At the same time, the close-range camera can collect the visitor's facial three-dimensional data at a close distance, and the facial details of the visitor are collected through multiple close-range cameras. Then, the collected images are integrated by technical means such as vector superposition and noise reduction, so that the visitor's facial three-dimensional data can be collected quickly and with high quality, thereby ensuring the accuracy and efficiency of facial recognition.

[0056] Preferably, the personnel information module includes:

[0057] Biometric information database, used to store the biometric information of material managers;

[0058] Attendance unit, used to input the on-the-job status information of the storage material manager;

[0059] Additional marking unit, used to store marking information of material managers, including category, authority, and rating information;

[0060] The editing and calling unit is used to modify or call the storage information of the biometric information database, attendance unit, and additional marking unit according to the input instructions.

[0061] Through the above technical solution, the biological information of the material storage manager and the on-the-job status information of the material manager in the personnel information module are stored in the form of independent partition storage, and the category, authority, rating and other information of the material manager are marked through additional marking units. In this way, the detailed information of a specific material management manager can be quickly located through the corresponding label or index. This marking can be based on the manager's category, authority, rating and other attributes to facilitate quick access and analysis.

[0062] Independent partition storage allows the system to flexibly add, delete or modify partitions without affecting other data. This design enables the system to adapt to changing needs and is easy to expand and maintain. Storing biological information and on-the-job status information in different partitions can reduce interference between different types of data and improve data integrity and accuracy. By setting up edit call units, the data of each module can be modified by inserting and overwriting. The correlation between data is low, and data can be modified and supplemented efficiently.

[0071] The present invention will be described in further detail below in conjunction with the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom" and "top", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0072] Example:

[0073] A hazardous chemicals process management system, referring to Figure 1 , including a production management module 1, a material storage module 2, a personnel information module 3, a management decision module 4, a voucher data terminal 5 and a verification terminal 6.

[0074] The production management module 1 is used to input the production plan and generate a sequential material list according to the production plan. The sequential material list includes the material type and the corresponding collection time and collection quantity. The production management department usually has the login management authority to the production management module 1. The production management department arranges orders according to the order situation, personnel situation, and financial situation, and then inputs the production plan through the production management module 1. The production management module 1 uses logical operations to intelligently generate a sequential material list, thereby ensuring that the hazardous chemicals are collected through the node elements on the sequential material list, which can meet the production needs well and will not cause online stagnation and accumulation of materials, thereby achieving the purpose of lean production.

[0076] The material storage module 2 is usually controlled by the warehouse management department with login management authority. The electronic tag 21 can collect RFID or NFC technology. The data reading and writing unit 22 uses an RFID reader or NFC device corresponding to the electronic tag 21. When hazardous chemicals are produced or circulated, when passing through key nodes, the corresponding information of the hazardous chemicals is written into the electronic tag 21 through the data reading and writing unit 22. In this way, when hazardous chemicals are circulated, the information management system can comprehensively monitor the entire life cycle of hazardous chemicals to ensure that hazardous chemicals are controllable and traceable during the circulation process. The in-warehouse information is partitioned and stored and managed with the in-warehouse information and out-of-warehouse information, which can further ensure the security of the data and facilitate further inventory and verification of hazardous chemicals in the warehouse.
