At present, with the increasingly fierce market competition, it is very important for enterprises to improve production efficiency and reduce operating costs. Intelligent warehousing and logistics management is widely used in various industries. It designs and establishes a complete set of warehousing management processes, improves warehousing turnover, reduces the occupation of operating funds, turns frozen assets into cash, and reduces costs due to warehousing elimination. An important part of improving production efficiency.
The existing warehouse management systems of enterprises usually use barcode labels or manual warehouse management documents. These management methods have obvious shortcomings:
-Barcode management: easy to copy, not anti-fouling, not moisture-proof and can only be read at close range.
-Manual input: The work is cumbersome, and the data volume is prone to errors and omissions, which increases the labor cost of the warehousing link. The heavy workload of manual inventory results in a long inventory cycle, and the missing or stolen goods cannot be detected in time, which makes warehouse management very cumbersome and wastes a lot of time.
Hope to solve the following problems in warehouse management:
(1) Lack of accuracy in inventory statistics: Due to unreadable barcodes or some human errors, inventory statistics are often not very accurate, which affects the distribution center to make correct decisions.
(2) Irregular filling of orders: Many orders are not filled correctly, so it is difficult to ensure that the distribution center can send the correct quantity of the required goods to the correct place every time.
(3) Cargo loss: The loss of goods during transportation is always a problem that plagues the distribution center. The loss is caused by the wrong location of the goods, or the loss of the goods due to theft, or because of errors in packaging or shipping. According to a US survey, the loss of goods in the retail industry can reach 1.71% of sales.
(4) Counting the goods: The traditional method is very inefficient in clearing the goods, and in order to know the inventory status of the goods in time, it needs to be counted at any time, which requires a lot of manpower and material resources.
(5) Labor cost: labor cost has become a serious problem. Statistics show that the proportion of labor cost in the entire supply chain cost has risen to about 30%.

System hardware structure
•Warehouse management application server: run warehouse management application system;
•Database server: store material warehousing data;
•Ethernet switch: Servers and fixed card readers are connected via Ethernet;
• Card opener: read the code of the electronic labelelectronic labelWrite data, such as item code, etc.;
•Wireless AP: The wireless AP is connected to the Ethernet switch using an Ethernet cable to achieve wireless network coverage in the warehouse. The handheld card reader with integrated wireless module can remotely access the warehouse management application server through the wireless AP to realize online operation;
•Handheld card reader: The handheld RFID card reader can read and write electronic tags. Since the handheld card reader has a built-in wireless module, it can remotely access the server to realize online data transmission and data interaction;
•Electronic label: The electronic label has a unique code, which can be bound with warehouse materials to identify items or assets. Active or passive electronic labels can be selected according to the on-site environment;
• MMS MODEM: Various reports can be pushed to the administrator’s mobile phone in the form of MMS.

Warehouse Management – Warehousing Management
It is assumed that all products are attached before being put into storageRFIDLabel, and the information of the label is correctly corresponding to the information system. Then, during the cargo warehousing operation stage, the warehouse management unit can use the RFID sensing device to automatically count and log the warehousing cargo data.
Warehouse Management – Inventory Management
Or set up RFID sensing equipment on the shelf to achieve real-time query/update storage location information, or the function of unmanned inventory.
Warehouse Management – Outbound Management
Warehouse Management – Outbound Management
• Provide a set of identification numbers for logistics boxes, and use this number to bring out the item information in the database.
• And make use of the wireless induction characteristics of RFID technology to carry out other derived applications.
Solution–Logistics Management
System Features
The goal of the RFID warehousing logistics management system is to establish a fast channel based on RFID technology in the warehouse system to achieve efficient warehouse management and high-speed automatic recording of receipts and shipments. The system is supported by RFID middleware, which consists of multiple processes such as receipt, warehousing, inventory, and delivery. Each function can be operated independently or smoothly connected to form a complete warehousing and logistics management based on RFID automatic identification technology. system.
> Automatic and precise updating of various information;
When the goods are in and out of the warehouse and need to be updated, just repair the corresponding data through the handheld PDA to complete the update of the warehouse; or through the query database, find the corresponding type of goods to update the data.
> Inquire and track cargo information;
Log in to the system software terminal, search for the specific information of the goods to be queried, and transmit the searched information to the PDA, so that the identification plate can be easily found and the goods can be tracked;
> Cargo location inquiry, dynamic allocation of cargo locations, and random storage, so as to maximize the use of storage space;
Log in to the system software terminal, query the cargo location information, and realize the dynamic allocation of goods according to the cargo location storage space information, so as to maximize the use of storage space
> Realize the dynamic and comprehensive allocation of human and material resources;
In the warehouse management process, not only the support of the system terminal database, but also the manual hand-held PDA is required to operate, thus realizing the dynamic and comprehensive allocation of human and material resources.
> Warehouse system comprehensive inventory function;
When carrying out warehouse system inventory, the passive label on the identification plate can be read through the handheld PDA, the statistics of the goods can be carried out, and the data can be returned to the system terminal for processing and inventory.
> Random inspection and inventory within the warehouse;
Log in to the system terminal, immediately search for a certain type of goods, obtain the relevant information of the goods, and transmit the data to the handheld PDA. The staff can find the corresponding cargo space according to the transmitted data, and complete the random inspection and inventory work in the warehouse;
> Real-time statistical reports, summarizing all kinds of information.
Through the handheld PDA to read the warehouse identification plate, obtain the information, and transmit it to the system terminal, which can realize the system summary of the warehouse and make statistical reports.
