With increasingly fierce market competition, it is vital for companies to increase production efficiency and reduce operating costs. Warehousing management is widely used in various industries to design and establish a complete warehousing management process, improve storage turnover rate, reduce the occupation of working capital, make frozen assets into cash, reduce the cost caused by the warehousing phase out, and increase the production for enterprises. An important part of efficiency.
Currently, warehousing management systems often use barcode labels or manual warehouse management documents to support their own warehouse management. However, the barcode's features of easy copying, non-fouling, and moisture-proof, as well as the cumbersome nature of manually writing documents, are likely to cause human losses, making the current domestic warehouse management always suffer from defects.
With the introduction of the latest technology products, RFID radio tags can fundamentally solve the above problems. Based on Radio Frequency Identification (RFID) technology, Tsinghua Tongfang has developed the RFID Warehouse Management System based on the actual situation and needs in warehouse management. In the application of this system, the electronic tags are sealed in a card-like form and are affixed to the packaging or pallet of each cargo, and the specific information of the goods, storage location and other information are written in the tags. At the same time, when the goods are entering or leaving the warehouse, detailed information of the delivery party can be written, and fixed or portable card readers can be set in the warehouse and distribution channels to identify and detect the circulation of goods.
system structure
RFID warehousing management system consists of business management software, RFID tag issuance system and RFID tag identification and collection system. These systems are linked to each other to complete the various processes of article management. The back-end database management system is the core of the entire system, and RFID identification and collection is the basis and means to realize the management function.
The back office management software consists of a central data server and a management terminal and is the system's data center. Responsible for communication with the handset, convert the data uploaded by the handset into the database of the back-office business warehouse management system, and store and process the label management information, the issuance label, and the collected label information.
The RFID tag issuance system consists of an electronic tag special printer and tag production management software. It is responsible for the completion of the writing of location tag, article tag, box tag information and label surface information printing.
The electronic label printer adopts an industrial-grade thermal transfer printer with a built-in non-contact reader. It can print preset information on the label surface while writing information on the label chip. The core of the label production management software is a dynamic connection library of label production functions. It is embedded in the background system and provides a development interface function for operating the printer production label for the back-end warehouse management system. Based on the dynamic library also provides an independent labeling software, which can manually input the label data to facilitate the temporary production of labels.
The RFID tag identification and collection system can collect tag information through a handset or a fixed location terminal, complete the storage of tag data, and exchange data with the management center through the RFID middleware.
System functions
The system uses electronic tags to perform tag management for each object that needs to be managed within its management cycle. The management personnel can use this system to know in real time the information such as the nature, status, location, and historical changes of each managed object (item), and take corresponding management countermeasures and measures based on this information, so as to improve the operation level and management of the use unit. The purpose of quality. Can be widely used in military, railway, health care, tobacco, telecommunications and other industries and institutions of warehousing management.
According to requirements, the system includes several modules: system management, label production, storage management, outbound management, inventory management, allocation management, return management, report analysis, and terminal data collection procedures.
System Management: System settings and system user information and permissions.
Label production: According to the cargo information entered in the warehouse receipt and labeling application form, an electronic label for each item is generated, a label serial number, a product name, and a model specification are printed on the surface of the label, and detailed product information is recorded in the chip.
Storage management: When entering the warehouse, the warehouse manager checks each item according to the order list for inspection. After inspection, it is sent to the warehouse custodian for delivery to the warehouse. The warehouse clerk holds the handheld device to scan the shelf location tag and the tag on the inbound article and enters the quantity of the article for storage registration. The data is logged into the storage operation data table in the handheld and then the article is placed on the designated location.
If you need to store items in a box, you also need to scan the box labels to update the handset inner box details.
After all the items have been put into storage, the handheld is handed over to the administrator. The administrator will import the data into the back-end management database to complete the storage operation.
After this process, the position, quantity, specification, and model of each item in the warehouse can be found out at a glance in the warehouse management software, and the storage status can be visualized.
Outbound management: When leaving the warehouse, the warehouse administrator queries the storage status according to the request for picking, and then makes a pre-delivery order; the custodian picks up the items in the designated location according to the pre-shipment order, and scans the location label with the handset. And the item label will register the outbound information, and the data will be recorded in the handset outbound data table; all the outbound items will be taken out and the outbound information will be uploaded to the mainframe, compared with the pre-shipment list, and be recorded according to the actual amount. .
Inventory Management: Uses a handheld data collection terminal for data collection, such as tagging items, placing shelves, and the number of items. The system can automatically generate or manually select the inventory task table to perform inventory operations based on pre-defined product categories. The inventory operations mainly scan product labels and corresponding location information. After the data is uploaded, the system will automatically list the products already sold and the products that have not been sold, and perform operations such as overage and loss according to demand.
Transfer management: When there is a transfer situation, different transfer procedures are selected according to the allocation situation.
Return management: When the customer returns, it can check whether the product belongs to this customer, sales time, etc. by reading the product label, and it is convenient to query the sales information at that time for effective supervision and management. For products that need to be confirmed for return, the handheld will write the current time into the return time field in the tag when it reads the tag.
Report Analysis: Statistical analysis of system data and generation of related reports.
System Features
1. Combine the entire warehouse management and RFID technology to efficiently complete various business operations, improve warehouse management, and increase efficiency and value;
2. To increase the recognition rate of articles entering and leaving the library, without opening the box for inspection, and identify multiple articles at the same time, to improve the efficiency of storage and storage;
3, reduce the inventory cycle, improve the real-time data, real-time dynamic inventory control, to achieve visual management of inventory items;
4. The use of radio frequency technology can greatly improve the efficiency and accuracy of the picking and distribution process, and speed up the distribution, reduce labor and reduce distribution costs;
5, accurate control of material conditions, optimize the rational inventory.
