Finally, deliver the outbound materials to the corresponding department or transport vehicle to complete the material outbound process. This series of operations ensures the efficiency and accuracy of the material outbound, providing strong guarantee for the smooth progress of the engineering project.
[0019] In a preferred embodiment, in step S5, the specific process method includes:
[0020] S5-1: Initialization:
[0021] Create a graph representing the warehouse layout, where nodes represent locations in the warehouse and edges represent the feasible paths between two locations.
[0022] Assign a weight to each edge. The weight is the distance, time cost, or comprehensive cost.
[0023] S5-2: Set the starting point and the ending point:
[0024] Starting point: The current inventory location of the materials.
[0025] Ending point: The outbound destination of the materials.
[0026] S5-3: Apply Dijkstra's algorithm:
[0027] Use Dijkstra's algorithm to start from the starting point and calculate the shortest paths to all other nodes in the graph.
[0028] Maintain two sets: the set of processed nodes and the set of unprocessed nodes.
[0029] Initialize the distance from the starting point to itself as 0 and the distance to other nodes as infinity.
[0030] S5-4: Iteratively update the paths:
[0031] Find the node with the shortest distance from the starting point in the set of unprocessed nodes and mark it as processed.
[0032] Update the distances of the adjacent nodes of this node. If the distance to an adjacent node through the current node is shorter, update the shortest distance of the adjacent node;

[0034] When the end point is marked as processed, the algorithm terminates;
[0035] S5-6: Output the optimal path:
[0036] Trace back from the end point to the start point and output the optimal transfer path;
[0037] The calculation formula is:
[0038] d(u,v)=min(d(u,v),d(u,w)+w(w,v))
[0039] Where the parameter definitions are:
[0040] d(u,v) represents the shortest distance from node u to node v;
[0041] d(u,w) represents the shortest distance from node u to node w;
[0042] w(w,v) represents the edge weight from node w to node v;
[0043] The specific calculation steps for calculating the shortest paths from the start point to all other nodes in the graph are as follows:
[0044] Initialize the distance array: d[s]=0, for all other nodes v, d[v]=∞;
[0045] Iteratively update the distances: For each processed node u, traverse all its adjacent nodes v; if d[u]+w(u,v)<d[v], then update d[v]=d[u]+w(u,v)
[0046] Select the next node to be processed: Select the node v that makes d[v] the smallest from the set of unprocessed nodes and mark it as processed.
[0047] In a preferred embodiment, in step S6, first analyze the transfer requirements of the materials, including the starting point, end point, time limit, and detailed information on the material characteristics; according to the results of the requirement analysis, use the path planning algorithm to generate the optimal transfer path; after generating the path, conduct a simulation test in the system to check whether there are conflicts, congestion, or infeasible situations in the path; after the simulation test is correct, confirm the path planning result and send the planning result to the execution department.
[0048] In a preferred embodiment, in step S7, first, the material flow monitoring system of the warehouse is started. This system integrates various monitoring devices such as RFID reading and writing devices, cameras, and sensors. Through these devices, the material flow data is collected in real time, including the detailed information of the location, status, and flow time of the materials. The collected data will be transmitted to the server in the monitoring center in real time. The server processes and analyzes the data to generate a real-time monitoring screen and report of the material flow. The monitoring personnel can view the material flow situation in real time through the monitoring large screen or terminal device, including the current location, flow path, and time-consuming information of the materials. At the same time, the system will set an early warning threshold. When an abnormal situation occurs in the material flow, the system will automatically send out an early warning message. After receiving the early warning message, the monitoring personnel will immediately analyze and process it, determine the cause of the abnormality, and take corresponding measures to correct it. After the processing is completed, the processing result will be fed back to the monitoring system to update the flow status of the materials. During the entire monitoring process, all data and processing records will be saved by the system for subsequent query and analysis. Through this series of detailed monitoring operations, the efficiency, safety, and controllability of the material flow are ensured.
[0049] In a preferred embodiment, in step S8, first, the system will automatically record all data during the material flow process, including the detailed information of the inbound, outbound, location change, flow time, and abnormal situation of the materials. These data will be stored in the database to ensure the integrity and traceability of the data. The recorded data will be regularly sorted and analyzed to generate various reports and statistical charts.
[0050] In a preferred embodiment, in step S9, first, the system will automatically check whether all material flow tasks have been completed, including all links such as inbound, outbound, path planning, and monitoring. After confirming that all tasks are completed, the system will generate a final flow report to summarize the overall situation of this flow, including flow efficiency, abnormal handling, and optimization suggestions. The final report will be submitted to the relevant departments and leaders as the basis for subsequent improvement and decision-making. At the same time, the system will release the resources occupied during this flow process, including RFID tags, reading and writing devices, and storage space, to prepare for the next flow. The relevant processes and threads of this flow will be closed to ensure the effective utilization of system resources. Finally, the data of this flow will be backed up and archived to ensure the long-term preservation and traceability of the data. After the algorithm ends, the system will enter the standby state, waiting for the start of the next flow task. Through this series of ending operations, the efficiency, orderliness, and sustainability of the material flow management are ensured.
[0051] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are:
[0052] 1. In the present invention, by implementing a method for constructing the material flow path based on radio frequency identification of electric power materials and using the Dijkstra algorithm for path planning, the efficiency and accuracy of material flow have been significantly improved. In the initialization stage, by creating a warehouse layout diagram and assigning edge weights, the system can accurately reflect the actual environment of the warehouse, providing a basis for subsequent path calculations. After setting the starting point and the ending point, the Dijkstra algorithm can quickly calculate the shortest path from the starting point to the ending point, avoiding the blindness and uncertainty in traditional manual planning. Taking the warehouse layout in the example as an example, the optimal path from point A to point F is A -> B -> E -> F, and the total cost is 5. This result is automatically calculated by the system, which is not only fast but also highly accurate. This efficient path planning reduces the waiting time and transportation distance of materials during the flow process, improves the flow speed of materials, ensures that materials can reach the destination on time, and thus improves the overall work efficiency.
[0053] 2. In the present invention, it helps to optimize resource allocation and reduce management costs. Through the precise tracking and real-time monitoring of materials achieved by RFID technology, combined with the path planning of the Dijkstra algorithm, warehouse managers can arrange storage space and transportation resources more reasonably. In the example, the unnecessary transportation links are avoided through the calculated optimal path, reducing transportation costs. In addition, the system automatically records and analyzes the flow data, providing valuable decision-making support for managers, enabling them to adjust inventory strategies and flow plans according to actual needs, and avoiding resource waste. In the long run, this data-based decision-making method helps to optimize inventory management, reduce inventory holding costs and transportation costs. At the same time, systematic management and automated processes reduce the need for manual intervention, reducing labor costs and the risk of human errors. In summary, this method has played a significant beneficial effect in optimizing resource allocation and reducing management costs. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0056] Embodiment:
[0057] Referring to Figure 1-2 , a method for constructing a material flow path based on radio frequency identification of electric power materials, the method includes the following steps:
[0058] S1: Material Label Making and Binding: Make a unique Radio Frequency Identification (RFID) label for each piece of power material, and store basic information of the material such as name, model, and production date in the label; firmly bind the made RFID label to the corresponding power material to ensure that it will not fall off during the transfer process;
[0059] S2: Deployment of Reading and Writing Devices: Deploy RFID reading and writing devices at the entrance, exit, and key transfer nodes of the material warehouse; ensure that the reading and writing devices can stably and accurately read and write RFID label information.
[0060] S3: Material Inbound Registration: When materials enter the warehouse, automatically read the material label information through the RFID reading and writing device at the entrance; compare the read information with the warehouse management system to confirm the inbound of materials and update the inventory status.
[0061] S4: Material Outbound Registration: When materials are out of the warehouse, read the material label information through the RFID reading and writing device at the exit; the system automatically records information such as the outbound time and outbound destination, and updates the inventory status.
[0062] S5: Path Planning and Optimization: Calculate the optimal transfer path using the path planning algorithm based on the outbound destination of the material and the current inventory location; consider factors such as warehouse layout, material size, and weight to ensure the feasibility and efficiency of the path.
[0063] S6: Path Execution and Monitoring: Guide warehouse staff to carry materials according to the planned path; real-time monitor the transfer location and status of materials through RFID reading and writing devices deployed at key nodes.
[0064] S7: Exception Handling and Adjustment: When abnormal situations (such as equipment failures, path blockages, etc.) occur during the material transfer process, the system issues an alarm in a timely manner; adjust the transfer path according to the actual situation to ensure that the materials can reach the destination smoothly.
[0065] S8: Data Recording and Analysis: The system automatically records information such as the complete transfer path and time consumption of each piece of material. Regularly analyze the collected data to optimize the warehouse layout and transfer path and improve the material transfer efficiency.
[0066] S9: System Maintenance and Update: Regularly maintain and calibrate the RFID reading and writing devices to ensure the stable operation of the devices. Update and upgrade the system according to actual needs to adapt to new material transfer requirements and technological developments.
[0067] In step S1, start a dedicated RFID label printer and input the detailed information of each piece of power material, including name, model, production date, etc. The printer will print this information together with a unique identification code on the RFID label. After printing, the staff will conduct a quality inspection on the label to ensure that the information on the label is clear and readable, the identification code is unique and error-free. Next, place the power material to be bound on the operating table, ensuring that the surface of the material is clean and flat for easy label binding. Use a high-temperature resistant adhesive or a special strap to firmly bind the RFID label to the designated position of the material, usually a place that is easy to scan and not easily damaged. After binding, check again whether the label is firm to ensure that it will not fall off during the material flow process. Finally, use an RFID reading and writing device to enter the basic information of the material into the system, associate it with the identification code of the label, and confirm that the system has been successfully entered. This series of meticulous operations ensures that each piece of material has a unique and tamper-proof "identity card", laying a solid foundation for subsequent flow management.
[0068] In step S2, select the appropriate model and quantity of RFID reading and writing devices according to the scale, layout of the warehouse and the needs of material flow. Then, conduct a detailed location planning to determine the specific locations of the warehouse entrance, exit and key flow nodes, which are usually selected in places where the material flow is frequent and the device installation is easy. The installation personnel will install the RFID reading and writing devices, including antennas, readers, etc., at these locations and ensure that the devices are firmly and safely installed. After the device installation is completed, conduct detailed debugging work, including the adjustment of parameters such as signal strength, reading and writing range, data transmission speed, etc., to ensure that the device can stably and accurately read and write RFID label information. Next, connect the reading and writing device to the warehouse network system, conduct network configuration and testing to ensure that the data can be transmitted to the background system in real time and accurately. To ensure data security, set the access rights of the device to prevent unauthorized access and data leakage. Finally, conduct a comprehensive device test, including actual reading and writing tests and simulated flow tests. After confirming that all devices are running normally and meet the requirements, the deployment process is completed.
[0069] In step S3, first, a preliminary inspection is carried out to confirm that the appearance of the materials is intact and the quantity is correct. Then, an RFID reader / writer device is used to read the RFID tag information on the materials, which includes the name, model, production date, etc. of the materials. After the reading is completed, the read information is carefully checked against the incoming goods list to ensure that the material information is correct and consistent with the incoming goods list. After the check is correct, according to the storage strategy of the warehouse and the current inventory situation, a suitable storage location is allocated for the materials. After the allocation is completed, the staff will move the materials to the designated storage location and ensure that they are neatly and stably placed. At the same time, the incoming information of the materials, including detailed data such as the incoming time, location, and person in charge, is entered into the system. After the entry is completed, it is confirmed again that the system has successfully registered all information to ensure the accuracy and integrity of the material incoming registration. This series of operations not only realizes the rapid incoming of materials but also provides convenience for subsequent management work such as outgoing and inventory taking.
[0070] In step S4, first, the outgoing requests from each department are received, and these requests include detailed information such as the name, model, quantity, and outgoing time of the materials. After receiving the requests, the storage location and inventory status of the requested materials are queried in the system to confirm that the materials can be outgoing and the quantity is sufficient. Then, an RFID reader / writer device is used to read the RFID tag information of the materials to be outgoing, and these information are carefully checked against the outgoing requests to ensure that the outgoing materials are correct and consistent with the requests. After the check is correct, the staff will move the materials to the outgoing area and ensure the safety and integrity of the materials during the handling process. At the same time, the outgoing information of the materials, including detailed data such as the outgoing time, destination, and person in charge, is updated in the system. After the update is completed, it is confirmed again that the system has successfully registered all information to ensure the accuracy and timeliness of the material outgoing management. Finally, the outgoing materials are delivered to the corresponding department or transport vehicle to complete the material outgoing process. This series of operations ensures the efficiency and accuracy of the material outgoing and provides a strong guarantee for the smooth progress of the engineering project.
[0071] In step S5, the specific process methods include:
[0072] S5-1: Initialization:
[0073] Create a graph (Graph) to represent the warehouse layout, where the nodes (Nodes) represent the locations in the warehouse (such as shelves, entrances and exits, etc.), and the edges (Edges) represent the feasible paths between two locations.
[0074] Assign a weight (Weight) to each edge, and the weight can be distance, time cost, or comprehensive cost (considering factors such as material size and weight).
[0075] S5-2: Set the starting point and the ending point:
[0076] Starting point: The current inventory location of the materials.
[0077] Destination: The destination where materials are shipped out.
[0078] S5-3: Apply Dijkstra's algorithm:
[0079] Use Dijkstra's algorithm to calculate the shortest paths from the starting point to all other nodes in the graph.
[0080] Maintain two sets: the set of processed nodes and the set of unprocessed nodes.
[0081] Initialize the distance from the starting point to itself as 0, and the distance to other nodes as infinity.
[0082] S5-4: Iteratively update the paths:
[0083] Find the node with the shortest distance from the starting point in the set of unprocessed nodes and mark it as processed.
[0084] Update the distances of the adjacent nodes of this node. If the distance to an adjacent node through the current node is shorter, then update the shortest distance of the adjacent node.
[0085] S5-5: Termination condition:
[0086] When the destination is marked as processed, the algorithm terminates.
[0087] S5-6: Output the optimal path:
[0088] Trace back from the destination to the starting point and output the optimal transfer path;
[0089] The calculation formula is:
[0090] d(u,v) = min(d(u,v), d(u,w) + w(w,v))
[0091] Where the parameter definitions are:
[0092] d(u,v) represents the shortest distance from node u to node v.
[0093] d(u,w) represents the shortest distance from node u to node w.
[0094] w(w,v) represents the edge weight from node w to node v;
[0095] The specific calculation steps for calculating the shortest paths from the starting point to all other nodes in the graph are as follows:
[0096] Initialize the distance array: d[s] = 0 (s is the starting point), for all other nodes v, d[v] = ∞;
[0097] Iterative update distance: For each processed node u, traverse all its adjacent nodes v; if d[u] + w(u, v) < d[v], then update d[v] = d[u] + w(u, v).
[0098] Select the next node to be processed: Select the node v with the minimum d[v] from the set of unprocessed nodes, and mark it as processed;
[0099] Assume that the warehouse layout is simplified as follows Figure 2 :
[0102] Edge weight: Represents the path cost (such as distance)
[0103] If you want to find the optimal path from point A to point F:
[0104] Initialization: d[A] = 0, and the rest are ∞.
[0105] Process point A and update the distances of adjacent points B and D: d[B] = 1, d[D] = 4.
[0106] Select point B and update the distances of C and E: d[C] = 3, d[E] = 2.
[0107] Select point E and update the distance of F: d[F] = 5.
[0108] Terminate and output the path: A -> B -> E -> F, and the total cost is 5.
[0109] Through the above steps, the Dijkstra algorithm can effectively calculate the optimal transfer path of electric power materials from the current inventory location to the outbound destination.
[0110] In step S6, first analyze the transfer requirements of the materials, including detailed information such as the starting point, ending point, time limit, and material characteristics. According to the results of the demand analysis, use advanced path planning algorithms, such as the Dijkstra algorithm or the A* algorithm, to generate the optimal transfer path. After generating the path, conduct a simulation test in the system to check whether there are conflicts, congestion, or infeasible situations in the path. After the simulation test is correct, confirm the path planning result and send the planning result to the execution department.
[0111] In step S7, first, start the material flow monitoring system of the warehouse. This system integrates various monitoring devices such as RFID readers / writers, cameras, and sensors. Through these devices, the material flow data is collected in real-time, including detailed information such as the location, status, and flow time of the materials. The collected data is transmitted to the server in the monitoring center in real-time. The server processes and analyzes the data to generate real-time monitoring images and reports of the material flow. The monitoring personnel can view the material flow situation in real-time through the monitoring large screen or terminal devices, including information such as the current location, flow path, and time-consuming of the materials. At the same time, the system sets warning thresholds. When abnormal situations occur in the material flow, such as overtime, path deviation, material damage, etc., the system will automatically send warning messages. After receiving the warning messages, the monitoring personnel will immediately analyze and process them, determine the cause of the abnormality, and take corresponding measures to correct it. After the processing is completed, the processing results are fed back to the monitoring system to update the flow status of the materials. During the entire monitoring process, all data and processing records are saved by the system for subsequent query and analysis. Through this series of detailed monitoring operations, the efficiency, safety, and controllability of the material flow are ensured.
[0112] In step S8, first, the system automatically records all data during the material flow process, including detailed information such as the inbound, outbound, location change, flow time, and abnormal situations of the materials. These data are stored in the database to ensure the integrity and traceability of the data. Regularly organize and analyze the recorded data to generate various reports and statistical charts, such as material flow reports, inventory reports, abnormal situation reports, etc. These reports provide a comprehensive view of the material flow, helping the management to understand the overall situation and trend of the material flow. According to the analysis results of the reports, the management can discover problems, optimize processes, and improve efficiency. At the same time, submit the generated reports and data analysis results to relevant departments and leaders as the basis for decision-making. In special cases, such as audits and investigations, historical data can be quickly queried to provide detailed data support. During the entire data recording and reporting process, ensure the accuracy, timeliness, and security of the data to provide strong support for the material flow management.
[0113] In step S9, first, the system automatically checks whether all material transfer tasks have been completed, including various links such as warehousing, outbound, path planning, and monitoring. After confirming that all tasks are completed, the system generates a final transfer report, summarizing the overall situation of this transfer, including transfer efficiency, exception handling, optimization suggestions, etc. The final report is submitted to relevant departments and leaders as a basis for subsequent improvement and decision-making. At the same time, the system releases the resources occupied during this transfer process, such as RFID tags, reading and writing devices, storage space, etc., to prepare for the next transfer. Close the relevant processes and threads of this transfer to ensure the effective utilization of system resources. Finally, back up and archive the data of this transfer to ensure the long-term preservation and traceability of the data. After the algorithm ends, the system enters the standby state, waiting for the start of the next transfer task. Through this series of ending operations, the efficiency, orderliness, and sustainability of material transfer management are ensured.
[0114] In the present invention, by implementing the method for constructing the material transfer path based on the radio frequency identification of electric power materials and using the Dijkstra algorithm for path planning, the efficiency and accuracy of material transfer are significantly improved. In the initialization stage, by creating a warehouse layout map and assigning edge weights, the system can accurately reflect the actual environment of the warehouse, providing a basis for subsequent path calculation. After setting the starting point and the ending point, the Dijkstra algorithm can quickly calculate the shortest path from the starting point to the ending point, avoiding the blindness and uncertainty in traditional manual planning. Taking the warehouse layout in the example as an example, the optimal path from point A to point F is A -> B -> E -> F, and the total cost is 5. This result is automatically calculated by the system, which is not only fast but also highly accurate. This efficient path planning reduces the waiting time and transportation distance of materials during the transfer process, improves the transfer speed of materials, ensures that materials can reach the destination on time, and thus improves the overall work efficiency.
[0115] In the present invention, it helps to optimize resource allocation and reduce management costs. Through the precise tracking and real-time monitoring of materials achieved by RFID technology, combined with the path planning of the Dijkstra algorithm, warehouse managers can arrange the storage space and transportation resources more reasonably. In the example, the unnecessary transportation links are avoided by the calculated optimal path, reducing the transportation cost. In addition, the system automatically records and analyzes the transfer data, providing valuable decision-making support for managers, enabling them to adjust the inventory strategy and transfer plan according to the actual needs, and avoiding resource waste. In the long run, this data-based decision-making method helps to achieve the optimization of inventory management, reducing the inventory holding cost and transportation cost. At the same time, the systematic management and automated processes reduce the need for manual intervention, reducing the labor cost and the risk of human errors. In summary, this method has played a significant beneficial effect in optimizing resource allocation and reducing management costs.
