Description

Technical Field

[0001] The present invention relates to the technical field of logistics management, and in particular to an intelligent logistics management system and method applied to natural uranium barrels. Background Art

[0002] Uranium and its compounds are the core fuel for nuclear power generation, and their logistics and transportation are a key link in the nuclear energy industry chain. Natural uranium drums, as containers for storing uranium and its compounds, play a crucial role in the logistics and transportation of uranium and its compounds. The key to the logistics and transportation of uranium and its compounds lies in the logistics and transportation of natural uranium drums, making the logistics management of natural uranium drums crucial.

[0003] Uranium and its compounds are radioactive substances. Therefore, the transportation of natural uranium drums containing them cannot be done using conventional logistics solutions and requires comprehensive logistics supervision. Current comprehensive logistics supervision plans lack specific regulations for the selection and storage of natural uranium drums. Furthermore, due to changes in road conditions, the frequency of vibrations experienced by uranium, its compounds, and natural uranium drums during transportation varies. These changes cannot be anticipated in time during route planning, posing a risk to human and environmental safety. Summary of the Invention

[0004] The object of the present invention is to provide a logistics intelligent management system and method applied to natural uranium barrels to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] Step S1: obtaining information of the natural uranium barrels by scanning the labels of the natural uranium barrels, and classifying the natural uranium barrels according to the information of the natural uranium barrels to obtain the natural uranium barrels to be used;

[0007] Step S1-1: Obtaining the production batch number of the natural uranium barrel and the type of uranium compound used for storage based on the label of the natural uranium barrel; confirming whether the natural uranium barrel has been used and the factory inspection results of unused natural uranium barrels based on the production batch number;

[0008] Step S1-2: Use unused natural uranium barrels with good factory inspection results as standby uranium barrels;

[0009] Step S1-3: Perform leakage risk detection on natural uranium barrels that have been used, have failed factory inspection results, or have no factory inspection results retrieved. The leakage risk detection includes:

[0010] Manual visual inspection of the barrel body to check for splicing, rust, weld cracks, or curling deformation, and to confirm compliance with the closure. After the manual visual inspection passes, an ultrasonic scanner is used to measure the thickness of the barrel steel plate, with a focus on corrosion-prone areas. A radiation meter is used to measure the radiation dose rate on the surface of the natural uranium barrel. The natural uranium barrel is then subjected to an airtightness test.

[0011] Step S1-4: Use the natural uranium barrels that have passed the leakage risk detection as standby uranium barrels, and classify the standby natural uranium barrels according to the types of uranium compounds for storage.

[0012] Step S2: Before transporting the natural uranium barrel to be used, the transportation qualifications of the transportation vehicle and the escort personnel are checked and real-time monitoring is performed during the transportation process;

[0013] Step S2-1: Check whether the transport vehicle is qualified to transport radioactive materials and whether the escort personnel are certified;

[0014] Step S2-2: Locate the transport vehicle in real time and upload its route to the supervision platform in real time;

[0015] Step S2-3: Install a pressure sensor at the bottom of the natural uranium barrel on the transport vehicle and a radiation monitor inside the transport vehicle. If abnormal pressure or radiation concentration is detected, an alarm is immediately triggered and the data is uploaded to the monitoring platform.

[0016] Step S3: The natural uranium to be used is packed in barrels and transported under full-chain radioactive safety management;

[0017] Step S3-1: Setting safety sensors, including temperature sensors, humidity sensors, radiation sensors, impact sensors, and sealing sensors; using the safety sensors to test the natural uranium barrels and feeding the data back to the monitoring platform in real time, with upper and lower thresholds set. If the safety sensors detect that the data exceeds the upper threshold or falls below the lower threshold, an alarm is immediately triggered;

[0018] Step S3-2: Deploy sensors on the transportation vehicle to obtain real-time network information and location information, and deploy concentrators on the transportation vehicle and along its travel path; the transportation vehicle predicts network changes based on the location information and network information, and automatically switches to connect to the concentrator with the most stable network fluctuations; and plan the transportation vehicle route based on the location information to avoid densely populated areas and areas prone to geological disasters;

[0019] Step S3-3: Deploy laser roughness meters along different travel routes, and obtain the road surface undulation wavelengths of different roads along the travel routes based on real-time observation data from the laser roughness meters; obtain the congestion level of the travel routes of the transport vehicle based on network information and location information, and predict changes in the road surface undulation wavelength and congestion level during transportation; and adjust the transportation strategy for the natural uranium barrels based on the changes in the road surface undulation wavelength and congestion level;

[0020] Adjustments to the transportation strategy for natural uranium drums include:

[0021] Step S3-4: obtaining material information of the natural uranium barrel through the label of the natural uranium barrel; and determining whether earthquake-resistant design is required during the transportation of the natural uranium barrel based on the material information of the natural uranium barrel;

[0022] Step S3-5: For transportation processes that do not require earthquake-resistant design, the transportation vehicle route is planned based on the location information to avoid densely populated areas and areas prone to geological disasters; for natural uranium barrels that require earthquake-resistant design, the maximum allowable bump frequency of the natural uranium barrel is set, and the maximum allowable speed of the transportation vehicle is calculated based on the road surface undulation wavelength:

[0023] v=f·λ

[0024] Where f is the maximum allowable bump frequency of the natural uranium barrel, v is the maximum allowable speed of the transportation vehicle, and λ is the wavelength of the road undulation;

[0025] A congestion level threshold is set, and when the congestion level exceeds the congestion level threshold, the transport route is dynamically switched to a route with a congestion level lower than the congestion level threshold.

[0026] Step S4: Clean the used natural uranium barrels, store them in a warehouse, and perform regular inspections and maintenance.

[0027] Step S4-1: After obtaining approval from the local radiation safety regulatory authority, clean the natural uranium barrels in accordance with the regulations of the local radiation safety regulatory authority;

[0028] Step S4-2: Classify and store the cleaned natural uranium barrels according to the type of uranium compounds to be stored, establish an inspection cycle, and inspect the barrel bodies of the natural uranium barrels according to the inspection cycle;

[0029] Step S4-3: Record the date, personnel, and test data of each inspection, and archive the records locally and online.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. This invention builds a full-process intelligent classification management system, relies on label information to accurately identify the use status and storage properties of natural uranium barrels, and comprehensively utilizes technologies such as factory inspection and review and multi-dimensional leakage risk detection to implement differentiated screening for barrels in different states. This strengthens the structure of the barrels to be used and the radiation safety line from the source, effectively reducing the risks and hidden dangers in subsequent links.

[0032] 2.

The present invention establishes a standardized management mechanism, implements barrel cleaning operations in strict accordance with radiation safety regulatory specifications, classifies and stores stored materials according to their properties, and formulates periodic inspection plans. With the help of electronic and paper dual archiving, inspection records are traceable, ensuring that the status of the barrel is controllable and the data is traceable throughout its life cycle, significantly improving management compliance and reliability.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Example 1: Figure 1 As shown, the present invention provides a technical solution, a logistics intelligent management method applied to natural uranium barrels, and the logistics intelligent management method includes the following steps:

[0038] Step S1: obtaining information of the natural uranium barrels by scanning the labels of the natural uranium barrels, and classifying the natural uranium barrels according to the information of the natural uranium barrels to obtain the natural uranium barrels to be used;

[0039] Step S1-1: Obtaining the production batch number of the natural uranium barrel and the type of uranium compound used for storage based on the label of the natural uranium barrel; confirming whether the natural uranium barrel has been used and the factory inspection results of unused natural uranium barrels based on the production batch number;

[0040] Step S1-2: Use unused natural uranium barrels with good factory inspection results as standby uranium barrels;

[0041] Step S1-3: Perform leakage risk detection on natural uranium barrels that have been used, have failed factory inspection results, or have no factory inspection results retrieved. The leakage risk detection includes:

[0042] Manual visual inspection of the barrel body to check for splicing, rust, weld cracks, or curling deformation, and to confirm compliance with the closure. After the manual visual inspection passes, an ultrasonic scanner is used to measure the thickness of the barrel steel plate, with a focus on corrosion-prone areas. A radiation meter is used to measure the radiation dose rate on the surface of the natural uranium barrel. The natural uranium barrel is then subjected to an airtightness test.

[0043] Step S1-4: Use the natural uranium barrels that have passed the leakage risk detection as standby uranium barrels, and classify the standby natural uranium barrels according to the types of uranium compounds for storage.

[0044] Step S2: Before transporting the natural uranium barrel to be used, the transportation qualifications of the transportation vehicle and the escort personnel are checked and real-time monitoring is performed during the transportation process;

[0045] Step S2-1: Check whether the transport vehicle is qualified to transport radioactive materials and whether the escort personnel are certified;

[0046] Step S2-2: Locate the transport vehicle in real time and upload its route to the supervision platform in real time;

[0047] Step S2-3: Install a pressure sensor at the bottom of the natural uranium barrel on the transport vehicle and a radiation monitor inside the transport vehicle. If abnormal pressure or radiation concentration is detected, an alarm is immediately triggered and the data is uploaded to the monitoring platform.

[0048] Step S3: The natural uranium to be used is packed in barrels and transported under full-chain radioactive safety management;

[0049] Step S3-1: Setting safety sensors, including temperature sensors, humidity sensors, radiation sensors, impact sensors, and sealing sensors; using the safety sensors to test the natural uranium barrels and feeding the data back to the monitoring platform in real time, with upper and lower thresholds set. If the safety sensors detect that the data exceeds the upper threshold or falls below the lower threshold, an alarm is immediately triggered;

[0050] Step S3-2: Deploy sensors on the transportation vehicle to obtain real-time network information and location information, and deploy concentrators on the transportation vehicle and along its travel path; the transportation vehicle predicts network changes based on the location information and network information, and automatically switches to connect to the concentrator with the most stable network fluctuations; and plan the transportation vehicle route based on the location information to avoid densely populated areas and areas prone to geological disasters;

[0051] Step S3-3: Deploy laser roughness meters along different travel routes, and obtain the road surface undulation wavelengths of different roads along the travel routes based on real-time observation data from the laser roughness meters; obtain the congestion level of the travel routes of the transport vehicle based on network information and location information, and predict changes in the road surface undulation wavelength and congestion level during transportation; and adjust the transportation strategy for the natural uranium barrels based on the changes in the road surface undulation wavelength and congestion level;

[0052] Adjustments to the transportation strategy for natural uranium drums include:

[0053] Step S3-4: obtaining material information of the natural uranium barrel through the label of the natural uranium barrel; and determining whether earthquake-resistant design is required during the transportation of the natural uranium barrel based on the material information of the natural uranium barrel;

[0054] Step S3-5: For transportation processes that do not require earthquake-resistant design, the transportation vehicle route is planned based on the location information to avoid densely populated areas and areas prone to geological disasters; for natural uranium barrels that require earthquake-resistant design, the maximum allowable bump frequency of the natural uranium barrel is set, and the maximum allowable speed of the transportation vehicle is calculated based on the road surface undulation wavelength:

[0055] v=f·λ

[0056] Where f is the maximum allowable bump frequency of the natural uranium barrel, v is the maximum allowable speed of the transportation vehicle, and λ is the wavelength of the road undulation;

[0057] A congestion level threshold is set, and when the congestion level exceeds the congestion level threshold, the transport route is dynamically switched to a route with a congestion level lower than the congestion level threshold.

[0058] Step S4: Clean the used natural uranium barrels, store them in a warehouse, and perform regular inspections and maintenance.

[0059] Step S4-1: After obtaining approval from the local radiation safety regulatory authority, clean the natural uranium barrels in accordance with the regulations of the local radiation safety regulatory authority;

[0060] Step S4-2: Classify and store the cleaned natural uranium barrels according to the type of uranium compounds to be stored, establish an inspection cycle, and inspect the barrel bodies of the natural uranium barrels according to the inspection cycle;

[0061] Step S4-3: Record the date, personnel, and test data of each inspection, and archive the records locally and online.

[0062] For example:

[0063] By scanning the labels on the natural uranium barrels, we can identify the natural uranium barrels used to store uranium hexafluoride and the natural uranium barrels used to store uranium dioxide. If both barrels are unused and have passed factory inspection, we will set them as standby natural uranium barrels.

[0064] The transport vehicle selected is a transport truck. Before transportation, it is checked whether the transport truck has the qualification to transport radioactive materials and whether the escort personnel are certified. After the inspection, the natural uranium barrel is transported to the designated area. During the transportation, the transport truck is positioned in real time, and a pressure sensor and a radiation detector are installed at the bottom of the natural uranium barrel. If abnormal pressure or radiation concentration is detected, an alarm will be immediately issued and the data will be uploaded to the supervision platform.

[0065] When storing uranium compounds in natural uranium barrels, full-chain radioactive safety management is adopted:

[0066] Set temperature sensors, humidity sensors, radiation sensors, impact sensors, and sealing sensors as safety sensors, and set upper and lower thresholds. When the data detected by the safety sensors exceeds the upper threshold or falls below the lower threshold, an alarm will be immediately sounded;

[0067] Deploy sensors on transport trucks to obtain real-time network and location information, and deploy concentrators on all possible routes and trucks. Based on network changes, the transport truck's network is switched to the most stable concentrator in real time. The transport truck's route is also planned in real time to avoid densely populated areas and areas prone to geological disasters.

[0068] Laser roughness meters are placed on different driving paths, and the road surface undulation wavelengths of different roads on the driving paths are obtained based on the real-time observation data of the laser roughness meters:

[0069] The preset vehicle speed is 60km / h and the sampling frequency of the laser roughness meter is 2000Hz;

[0070] Parallel movable laser roughness meters are set up on both sides of the road section with the same road conditions in front of the transport truck to determine the average height of the road. The road elevation is sampled according to the sampling frequency. The data obtained by the laser roughness meters on both sides are weighted averaged after removing outliers, and Fourier transform is performed to obtain the spectrum. The main peak frequency of the spectrum is identified. The wavelength corresponding to the sine wave of the main peak frequency is the wavelength of the road surface undulation.

[0071] For example, if the main peak frequency is 0.51 / m, the wavelength of the road undulation is

[0072]

[0073] At this time, the maximum allowable turbulence frequency of the natural uranium barrel is preset to 8Hz, so the maximum allowable speed is:

[0074] v = f·λ = 16 m / s = 57.6 km / s

[0075] If 57.6km / s is less than 60km / s, the vehicle speed is too fast and you should choose another driving route.

[0076] The congestion level is set to light, medium, or heavy according to navigation data. When the congestion level of the current driving route is medium or heavy, another driving route is selected.

[0077] After the use of natural uranium drums, the drums must be cleaned in accordance with the regulations of the local radiation safety regulatory authorities, subject to approval by the local radiation safety regulatory authorities.

[0078] Cleaned natural uranium barrels will be sorted and stored according to the type of uranium compounds used for storage, and inspection cycles will be established to inspect the barrels of natural uranium barrels according to the inspection cycles;

[0079] Record the date, personnel, and test data of each inspection, and archive the records locally and online.
