[0043] 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.

[0044] This invention discloses an intelligent management system for chemicals in nuclear power plants, which enables safe control over the entire lifecycle of chemicals, from warehousing and dispensing to use and disposal.

[0045] See Figure 1 The present invention discloses a schematic diagram of a chemical intelligent management system for a nuclear power plant. The system includes: a PC terminal 10, a storage control cabinet 20, a field intelligent cabinet 30, and a disposal control cabinet 40.

[0046] in:

[0047] The warehouse control cabinet 20 includes: a warehouse controller 21, and a first user identification module 22, a printing module 23 and an inventory management module 24 connected to the warehouse controller 21.

[0048] The first user identification module 22 is used to verify the user's operation authority on the warehouse control cabinet 20 and to send the verification result back to the warehouse controller 21.

[0049] In practical applications, when a user needs to operate the warehouse control cabinet 20, the first user identification module 22 can obtain the user's identity information through the employee card swiped by the user or the collected facial information. By matching the obtained user identity information with the pre-entered authorized user identity information, it verifies whether the user has the right to operate the warehouse control cabinet 20, and feeds back the verification result to the warehouse controller 21. When the first user identification module 22 verifies that the user's operation permission is successful, it can output a verification success message, allowing the verified user to perform chemical inventory management operations on the warehouse control cabinet 20.

[0050] The first user identification module 22 can be linked with the access control and security system. If the user's identity is not verified (e.g., unauthorized personnel or identity theft), the access control and security system will immediately refuse the door opening request and trigger an alarm (e.g., audible and visual alerts, notification of security personnel), thereby effectively preventing illegal intrusion.

[0051] The printing module 23 is used to generate a unique chemical QR code based on the basic chemical information entered by the user after the user's operation permission is verified, and then print it; at the same time, the chemical QR code is bound to the corresponding operation user information and uploaded to the warehouse controller for storage.

[0052] The basic information on chemicals includes at least the chemical material code and quantity.

[0053] Once user access is verified, the user can input the chemical material code and quantity on the operation interface of printing module 23. The chemical material code is a unique identifier designed for chemical materials, used to quickly and accurately identify and track specific chemicals in the production, warehousing, logistics, and management processes of an enterprise. The chemical material code is similar to a chemical's "ID number," using standardized coding rules to convert key information such as the chemical's name, composition, specifications, and hazards into combinations of numbers or letters, enabling systematic information management. Printing module 23 generates a unique chemical QR code for each smallest unit of the chemical. This QR code not only contains the chemical material code, but if the same chemical is packaged into multiple containers (e.g., number 1, number 2, etc.), the chemical QR code will also additionally associate with the corresponding chemical container number.

[0054] Chemical QR codes can be affixed to the outer surface of chemical containers to facilitate monitoring of subsequent operations such as chemical entry and exit.

[0055] The basic information about the chemicals may also include: the production batch number of the chemicals, the expiration date of the chemicals, etc. The specific details depend on actual needs, and this invention does not impose any limitations on them.

[0056] In practical applications, when a user whose operation permission has been verified enters the chemical material code on the operation interface of the printing module 23, the operation interface will automatically pop up the chemical name. At this time, the expiration date of the chemical can also be entered.

[0057] The inventory management module 24 is used to authorize users to perform inventory management operations on each smallest unit of chemicals after the user's operation permission is verified. It binds the chemical QR code, inventory management operation and corresponding operator information, and uploads them to the warehouse controller 21 for storage, along with the corresponding operation time. The inventory management operations include: inbound, outbound and / or return.

[0058] Once the user's operation permissions are verified, the user can perform inventory management operations on each smallest unit of chemicals, including chemical receipt, chemical issuance, and chemical return. During the process of the user performing inventory management operations, the chemical QR code, inventory management operation, and corresponding operator information are bound and uploaded to the warehouse controller 21 for storage. At the same time, the inventory quantity can be updated in real time, realizing traceability and safety control of chemicals, and improving the accuracy and compliance of chemical management.

[0059] The on-site smart cabinet 30 includes: an on-site controller 31, and a second user identification module 32, an access control module 33, and a first scanning module 34 connected to the on-site controller 31.

[0060] The second user identification module 32 is used to verify the user's operating authority over the on-site smart cabinet 30 and to send the verification result back to the on-site controller 31.

[0061] In practical applications, when a user needs to operate the on-site smart cabinet 30, the second user identification module 32 can obtain the user's identity information through the employee card swiped by the user or the collected facial information. By matching the obtained user identity information with the pre-entered authorized user identity information, it verifies whether the user has the right to operate the on-site smart cabinet 30 and feeds back the verification result to the on-site controller 31. When the second user identification module 32 verifies that the user's operation permission is successful, it can output a verification success message, allowing the verified user to perform chemical storage, requisition, and return operations on the on-site smart cabinet 30.

[0062] The second user identification module 32 can be linked with the access control and security system. If the user's identity is not verified (e.g., unauthorized personnel or impersonation), the access control and security system will immediately refuse the door opening request and trigger an alarm (e.g., audible and visual prompts, notification of security personnel), thereby effectively preventing illegal intrusion.

[0063] The access control module 33 is used to control the door of the smart cabinet 30 to open or close based on the received access control signal after the user's operation permission is verified.

[0064] Once the user's access permissions are verified, the access control module 33 monitors the employee card swipe signal in real time. If the access control module 33 detects that the user needs to perform an operation of storing, retrieving, or returning chemicals, it automatically triggers the access control opening command of the smart cabinet 30; after the user completes the chemical retrieval or return action, the access control module 33 immediately controls the cabinet door to close and records the operation log.

[0065] The first scanning module 34 is used to scan the QR code of the chemicals when they are stored, requisitioned and / or returned from the smart cabinet 30, and bind the chemical QR code with the corresponding user information. At the same time, it is uploaded to the field controller 31 in conjunction with the corresponding operation time.

[0066] After the user's operation permission is verified, when chemicals need to be stored or returned, the access control module 33 opens the door of the on-site smart cabinet 30 according to the received access control signal. The first scanning module 34 scans the chemical QR code to store or return the chemicals. At the same time, it can record information such as the quantity of chemicals stored or returned, storage location, operation time, and chemical hazards. After the operation is completed, the QR code of the stored or returned chemicals is bound with the corresponding storage or return operation user information and uploaded to the on-site controller 31 to realize the traceability and safety control of chemicals, and improve the accuracy and compliance of chemical management.

[0067] Similarly, when a user needs to collect chemicals after their operation permissions have been verified, the access control module 33 opens the door of the on-site smart cabinet 30 based on the received access control signal. The first scanning module 34 scans the chemical QR code to collect the chemicals, while recording information such as the collection time and quantity. After the operation is completed, the collected chemical QR code is bound to the corresponding collection operation user information and uploaded to the on-site controller 31 to achieve traceability and safe control of chemicals, thereby improving the accuracy and compliance of chemical management.

[0068] The scrap control cabinet 40 includes: a scrap controller 41, a third user identification module 42 and a second scanning module 43 connected to the scrap controller 41.

[0069] The third user identification module 42 is used to verify the user's operation authority over the scrap control cabinet 41 and to send the verification result back to the scrap controller 41.

[0070] In practical applications, when a user needs to operate the disposal control cabinet 40, the third user identification module 42 can obtain the user's identity information through the employee card swiped by the user or the collected facial information. By matching the obtained user identity information with the pre-entered authorized user identity information, it verifies whether the user has the right to operate the disposal control cabinet 40, thereby identifying the disposal user information, and feeding back the verification result to the disposal controller 41. When the third user identification module 42 verifies that the user's operation permission is successful, it can output a verification success message, allowing the verified user to perform chemical disposal operations on the disposal controller 41.

[0071] The third user identification module 42 can be linked with the access control and security system. If the user's identity is not verified (e.g., unauthorized personnel or impersonation), the access control and security system will immediately refuse the door opening request and trigger an alarm (e.g., audible and visual prompts, notification of security personnel), thereby effectively preventing illegal intrusion.

[0072] The second scanning module 43 is used to scan the chemical QR code corresponding to the chemical to be scrapped, bind the chemical QR code with the corresponding operation user information, and upload it to the scrapping controller 41 in conjunction with the corresponding operation time.

[0073] When the user's operation permission is verified and the chemical needs to be disposed of, the second scanning module 43 scans the chemical's QR code to perform the chemical disposal operation. The chemical to be disposed of is placed into the disposal collection container after the QR code is scanned, and the QR code of the chemical to be disposed of is bound with the corresponding operation user information and uploaded to the disposal controller 41, thereby completing the full process management of chemicals.

[0074] PC 10 is connected to warehouse control cabinet 20, on-site intelligent cabinet 30 and disposal control cabinet 40 respectively, and is used to obtain operation records and operator binding information of chemicals in the entire process of warehousing, outbound and disposal, so as to realize the monitoring of the entire life cycle of chemicals.

[0075] In practical applications, inventory management operations (including inbound, outbound and return) performed on chemicals based on the warehouse control cabinet 20, chemical QR codes, and corresponding operator information, operation time, etc., are all uploaded to the PC terminal 10 through the warehouse controller 21.

[0076] Based on the on-site smart cabinet 30, the chemical storage, requisition and return operations, chemical QR codes, corresponding operator information, operation time, etc. are all uploaded to the PC terminal 10 through the on-site controller 31.

[0077] The disposal operations performed on chemicals based on the disposal control cabinet 40, as well as the corresponding operator information, operation time, etc., are all uploaded to the PC terminal 10 through the disposal controller 41.

[0078] PC terminal 10 monitors the entire lifecycle of chemicals from warehousing and outgoing to disposal by acquiring operation records uploaded by warehouse control cabinet 20, on-site intelligent cabinet 30 and disposal control cabinet 40.

[0079] In summary, this invention discloses an intelligent management system for chemicals in nuclear power plants, comprising: a PC terminal 10, a storage control cabinet 20, a field intelligent cabinet 30, and a disposal control cabinet 40. The storage control cabinet 20 includes: a storage controller 21, a first user identification module 22, a printing module 23, and an inventory management module 24. It generates unique chemical QR codes based on basic chemical information and, when performing inventory management operations on chemicals in the storage control cabinet 20, links the chemical QR code, inventory management operation, operator information, and operation time in real time, enabling dynamic tracking of chemicals throughout the entire inventory management process. The field intelligent cabinet 30 includes: a field controller 31, a second user identification module 32, an access control module 33, and a first scanning module 34. When performing chemical entry, requisition, and return operations in the field intelligent cabinet 30, it links the chemical QR code, operation type, operator information, and operation time in real time, forming a complete operation record chain, enabling dynamic tracking of the entire process of chemical use from entry to return. The disposal control cabinet 40 includes a disposal controller 41, a third user identification module 42, and a second scanning module 43. When performing chemical disposal operations in the disposal control cabinet 40, it links the chemical QR code, the chemical disposal operation, the operator information, and the operation time in real time to form a complete chemical disposal record chain, enabling dynamic tracking of the entire chemical disposal process. The PC terminal 10 integrates the real-time operation records uploaded from the storage control cabinet 20, the on-site intelligent cabinet 30, and the disposal control cabinet 40 to construct a chemical lifecycle data chain. This enables dynamic monitoring and precise traceability of chemicals from warehousing, outbound, use to disposal, facilitating accident tracing and liability determination.

[0080] In one embodiment, see Figure 2 The present invention discloses a schematic diagram of the structure of an inventory management module. The inventory management module 24 includes: an inbound module 241, an outbound module 242, and a return module 243.

[0081] The warehousing module 241 is used to perform warehousing operations on chemicals, record the warehousing time, update the quantity of chemicals in the warehouse, bind the QR code of the warehousing chemicals and the corresponding warehousing operator, and upload the data to the warehouse controller 21 for storage, along with the corresponding warehousing time.

[0082] In practical applications, the system executes the following standardized warehousing process for each smallest unit of chemicals:

[0083] 1. Scan to trigger warehousing: Operators initiate the warehousing operation by scanning the unique chemical QR code (including material code and other information).

[0084] 2. Data Collection and Binding:

[0085] The system automatically records the entry time and updates the total quantity of chemicals in stock (e.g., "Add 5 bottles of chemical Y with material code X").

[0086] The chemical QR code, operator identity (verified via work card / account), and storage time are linked to form an unalterable operation record.

[0087] 3. Data Upload and Synchronization:

[0088] Once bound, the data is uploaded to the warehouse controller 21 for storage in real time. At the same time, the warehouse controller 21 pushes the "inbound status" and updated inventory information to the PC terminal 10. The PC terminal 10 dynamically displays the inventory chemical list (e.g., "Material code X - Current inventory: 10 bottles"), and supports querying by material code, batch number, and other dimensions.

[0089] The outbound module 242 is used to perform outbound operations on chemicals, record the outbound time, update the quantity of chemicals in stock and outbound, bind the QR code of the outbound chemicals and the corresponding outbound operator, and upload the data to the warehouse controller 21 for storage, along with the corresponding outbound time.

[0090] In practical applications, the system executes the following standardized outbound process for each smallest unit of chemicals:

[0091] 1. Scan to trigger outbound: Operators initiate the outbound operation by scanning the unique chemical QR code (including material code and other information).

[0092] 2. Data Collection and Binding:

[0093] The system automatically records the time of outbound shipment and updates the total amount of chemicals in stock (e.g., "reduced 5 bottles of chemical Y with material code X").

[0094] The chemical QR code, operator identity (verified via work card / account), and outbound time are linked to form an unalterable operation record.

[0095] 3. Data Upload and Synchronization:

[0096] Once bound, the data is uploaded to the warehouse controller 21 for storage in real time. At the same time, the warehouse controller 21 pushes the "outbound status" and updated in-stock information to the PC terminal 10. The PC terminal 10 dynamically displays the in-stock and outbound chemical lists, and supports querying by material code, batch number, and other dimensions.

[0097] The return module 243 is used to perform return operations on chemicals, record the return time, update the quantity of chemicals in stock and out of stock, bind the QR code of the returned chemicals and the corresponding inbound operator, and upload the data to the warehouse controller 21 for storage, along with the corresponding return time.

[0098] In practical applications, the system executes the following standardized return process for each smallest unit of chemicals:

[0099] 1. Scan to trigger return to inventory: Operators initiate the return to inventory operation by scanning the unique chemical QR code (including material code and other information).

[0100] 2. Data Collection and Binding:

[0101] The system automatically records the return time and updates the total amount of chemicals in stock (e.g., "Add 3 bottles of chemical Y with material code X").

[0102] The chemical QR code, operator identity (verified via work card / account), and return time are linked to form an unalterable operation record.

[0103] 3. Data Upload and Synchronization:

[0104] Once bound, the data is uploaded to the warehouse controller 21 for storage in real time. At the same time, the warehouse controller 21 pushes the "return status" and updated inventory information to the PC terminal 10. The PC terminal 10 dynamically displays the inventory and returned chemical lists, and supports querying by material code, batch number, and other dimensions.

[0105] In one embodiment, see Figure 3 The present invention discloses a schematic diagram of the structure of a field intelligent cabinet. The field intelligent cabinet 30 includes, in addition to, Figure 1 The field controller 31, the second user identification module 32, the access control module 33 and the first scanning module 34 shown may also include an environmental monitoring module 35.

[0106] The environmental monitoring module 35 is used to monitor the temperature and humidity inside the smart cabinet 30 on site, and outputs alarm information when the temperature and humidity exceed the preset range.

[0107] In practical applications, the environmental monitoring module 35 can integrate temperature and humidity sensors to monitor the temperature and humidity environment inside the intelligent cabinet 30 in real time. When either the temperature or humidity exceeds the preset safety range (e.g., temperature > 30℃ or humidity > 70%RH), an alarm message is immediately output to remind technicians to take effective measures in a timely manner.

[0108] The value of the preset range is determined based on the chemicals stored in the on-site smart cabinet 30, and this invention does not limit it.

[0109] In one embodiment, such as Figure 3 As shown, the on-site intelligent cabinet 30 may also include: an electronic metering module 36.

[0110] The electronic metering module 36 is used to weigh the chemicals taken from the on-site smart cabinet 30 and the chemicals returned to the on-site smart cabinet 30, and upload the weighed weight to the on-site controller 31.

[0111] When chemicals are needed for on-site work, after the user's identity is verified, the user can open the door of the on-site smart cabinet 30 to retrieve the chemicals. At the same time, the electronic metering module 36 weighs the chemicals, scans the chemical's QR code, and closes the door of the on-site smart cabinet 30. At this time, the time of retrieval is recorded to limit the return of the chemicals to the corresponding on-site smart cabinet 30 within a preset time period (e.g., 8 hours), or to enter the disposal process after use.

[0112] Similarly, when chemicals are returned to the on-site smart cabinet 30 after use, they need to be weighed to determine the usage weight of the chemicals based on their initial weight and return weight, thus enabling monitoring of chemical usage.

[0113] In practical applications, the field controller 31 is connected to the PC terminal 10. The field controller 31 can send relevant information on the issuance and return of chemicals to the PC terminal 10, and the PC terminal 10 can record information such as the quantity of chemicals issued / returned, work order number, operation time, and hazard.

[0114] In one embodiment, such as Figure 3 As shown, the on-site intelligent cabinet 30 may also include: a first intelligent monitoring module 37.

[0115] The first intelligent monitoring module 37 is used to monitor the environment and personnel operation of the on-site intelligent cabinet 30.

[0117] In this embodiment, the first intelligent monitoring module 37 monitors the environment and personnel operations of the on-site intelligent cabinet 30, recording in real time the operator's identity (work card / facial recognition), operation time, action type (such as opening the cabinet, retrieving materials, returning), and operation object (chemical QR code). The on-site controller 31 can automatically verify whether the operation complies with the authorization (such as only authorized personnel can open the cabinet containing highly toxic substances) and the procedure.

[0118] In one embodiment, such as Figure 3 As shown, the on-site intelligent cabinet 30 may also include: a ventilation module 38;

[0119] The ventilation module 38 is used to provide ventilation for the chemical storage area inside the on-site intelligent cabinet 30, ensuring that the air circulation inside the cabinet meets safety standards.

[0120] Ventilation module 38 is a core component that ensures the safe storage of chemicals in the on-site intelligent cabinet 30. Its design needs to be customized in combination with the characteristics of chemicals (such as volatility, toxicity, and flammability) and safety standards (such as OSHA, GB 15603, etc.).

[0121] The ventilation module 38 can be an exhaust fan, a filter device, etc., depending on the actual needs, and this invention does not limit it.

[0122] In one embodiment, such as Figure 3 As shown, the on-site intelligent cabinet 30 may also include: a fireproof module 39;

[0123] Fireproof module 39 is used to provide fireproof isolation protection for chemical storage areas in the event of external high temperatures or fire sources.

[0124] In this embodiment, by setting a fireproof module 39 on the on-site intelligent cabinet 30, fireproof isolation protection can be provided for the chemical storage area when there is external high temperature or fire source, preventing the chemicals in the cabinet from burning or exploding due to heat radiation or open flame.

[0125] In one embodiment, the warehouse control cabinet 20, the field intelligent cabinet 30, and the scrap control cabinet 40 may each include a network connection module.

[0126] The storage control cabinet 20, the on-site intelligent cabinet 30, and the disposal control cabinet 40 communicate with the PC terminal 10 through their respective network connection modules. This allows them to upload real-time operation records of the monitored chemicals to the PC terminal 10. The PC terminal 10 then integrates the real-time operation records uploaded by the storage control cabinet 20, the on-site intelligent cabinet 30, and the disposal control cabinet 40 to construct a chemical lifecycle data chain. This enables dynamic monitoring and precise traceability of chemicals throughout the entire process from warehousing, outbound, use to disposal, thus facilitating accident tracing and liability determination.

[0127] In one embodiment, see Figure 4 The present invention discloses a schematic diagram of the structure of a scrap control cabinet. In addition to the scrap controller 41, the third user identification module 42 and the second scanning module 43, the scrap control cabinet 40 may also include a second intelligent monitoring module 44.

[0128] The second intelligent monitoring module 44 is used to monitor the environment and personnel operations of the scrapped control cabinet 40.

[0129] In practical applications, the second intelligent monitoring module 44 can be a camera.

[0130] In this embodiment, the second intelligent monitoring module 44 monitors the environment and personnel operations of the scrap control cabinet 40, recording in real time the operator's identity (work card / facial recognition), operation time, action type (such as opening the cabinet), and operation object (chemical QR code). The scrap controller 41 can automatically verify whether the operation complies with the authorization (such as only authorized personnel can open the highly toxic substance cabinet) and the procedure.
