RFID Intelligent Warehouse Management System Solution

1. Description of the current application status

At present, many manufacturing companies are facing the problem of insufficient supervision of progress, quality and quantity control in the process of production and operation. There are also some challenges in warehouse management, such as large human factors in the warehouse and low accuracy, which makes it difficult to find goods, the warehouse inventory situation cannot be understood in a timely and accurate manner, and the maintenance cost is high.

In view of the current situation, these problems can be solved by applying the RFID intelligent warehouse management system. The system uses wireless radio frequency identification technology (RFID) and information analysis technology to collect commodity production information, material operation and processing information, work efficiency information and warehouse inventory information in real time, providing users with a complete set of intelligent solutions. Through the system platform, managers can obtain real-time data and understand comprehensive information such as production progress, employee work performance, product quantity, warehouse inventory, warehouse records and consumption. At the same time, electronic tags have established a connection channel for managers, senior company managers and front-line workers in the workshop. The information of each job can be directly fed back to the manager, and the relevant data can be counted in real time, the work performance can be evaluated, and the data can be analyzed from different angles, so that managers can make objective decision analysis and explore more meaningful data in depth. This can improve the production efficiency and management decision-making ability of the enterprise.

2. Design Principles

When designing the RFID intelligent warehouse management system, the following principles are followed:

1. Standardization: The system design complies with relevant national standards and industry standards.

2. Practicality: The system has the functional capabilities and levels required to complete the project, which is convenient for implementation and operation.

3. Innovation: The system is in line with the development direction of the industry and protects customers' investment in equipment.

4. Reliability: The system has the ability to complete functions within the specified conditions and time, and can work stably for a long time.

5. Economic efficiency: The system has the best cost-effectiveness under the premise of meeting performance requirements.

6. Scalability: The system can be maintained and upgraded normally without affecting current use.

3. Project goals

1. Standardized management

Improve the transparency and productivity of the production line, reduce the defective rate, improve the production management process, and reduce the backlog of semi-finished products on the production line. Through standardized management, improve personal responsibility awareness and save wage costs.

2. Automated operation

Realize the automatic collection of production data, reduce the workload of manual information input, automatically calculate production data, completely eliminate paper records, and reduce costs.

3. Data information

Real-time monitoring of production bottlenecks, accurate calculation of production capacity and life cycle, automatic generation of various intelligent analysis reports, and conversion of information in the production process into valuable data.

4. Refined in-and-out warehouse management

Through warehousing operations, relevant commodity information is input into the system in detail to avoid data loss caused by manual operations and ensure the accuracy and consistency of warehouse data.

5. Accurate inventory, saving time and effort

No longer need to print inventory sheets, manually record cargo information and summarize inventory. The system automatically records inventory data, handles cargo data recording and statistics, saving time and labor costs.

6. Real-time query and dynamic alarm

Users can query the latest inventory information at any time. The system automatically issues an alarm prompt based on the set minimum alarm value, and promptly warns of insufficient inventory.

7. Process standardization

By formulating production management processes, warehousing processes, warehouse internal management processes and product quality traceability processes, the efficiency of traditional production and warehousing managers is uniformly improved to ensure the standardization and consistency of processes.

IV. Brief description of the solution

4.1 Introduction to the business principles of the RFID system

4.1.1 Production process control

During the production process, the RFID tag is initialized and bound to associate the RFID tag with production-related information (batch number, date, number, name, etc.). In different production processes, the intelligent all-in-one machine is used to automatically collect and display relevant data and information records, and managers can monitor the production progress in real time through the platform. After the production is completed, the RFID tag, as the unique identifier of the finished product, can be traced back to all the production information of the product.

4.1.2 Finished product and waste storage control

By RFID channel or RFID handheld device, the finished product information is entered into the system in batches to realize automatic warehousing operation. Use RFID inventory machine or RFID handheld device to quickly find products in the warehouse. When it is necessary to ship out, according to the outbound plan formulated in the system, the RFID channel or RFID handheld device is used to quickly compound the cargo information and complete the outbound operation. When unauthorized goods leave the warehouse, the system will make a sound and report the information.

4.2 Introduction to the main functional modules of the RFID system

4.2.1 Process management

In the early stage of production, relevant production process information is set in the equipment to ensure accurate control of the production process.

4.2.2 Tag information binding

Before production, bind the RFID tag information with the production information to ensure data association and traceability in the production process.

4.2.3 Process flow management

After each process is processed, use a handheld terminal to bind the production information with the RFID tag information to realize the transmission and recording of production information.

4.2.4 Finished product entry

The operator generates a finished product entry order in the system based on the relevant information, and then batch-compounds the cargo information through the RFID entry channel or handheld terminal to complete the entry operation. After entry, the system automatically generates a storage number to guide the operator to install the goods.

4.2.5 Finished product search/inventory

To ensure the accuracy of inventory, use inventory equipment (inventory cart or handheld terminal) to search and inventory operations for finished products. The system automatically identifies the type and quantity of the storage location, compares it with the actual inventory, and generates an inventory difference table for warehouse staff to check.

4.2.6 Finished product outbound

Based on the outbound demand, a finished product outbound order is generated in the system, and the location and inventory status of the corresponding goods in the warehouse are queried. Prepare the goods according to the outbound order, and then scan the goods through the RFID delivery channel or handheld terminal to complete the outbound operation.
