Modern logistics is an advanced stage of traditional logistics development. It is based on advanced information technology and focuses on the comprehensive integration of service, personnel, technology, information and management. It is a combination of modern production methods, modern management methods, and modern information technology in the logistics field. Manifestation. It emphasizes the standardization and efficiency of logistics, and provides a high level of customer service at a relatively low cost. Fast, real-time, and accurate information collection and processing is an important foundation for realizing logistics standardization and efficiency. The application of RFID technology in modern logistics management will have a significant impact on it.

introduction
Container Freight Station (CFS) is a transportation service organization whose main business is packing, unpacking, consolidation and distribution. It also provides container road transportation, container management, customs declaration and inspection, container washing and repairing and other container transportation. Related services.
The RFID-based CFS intelligent warehouse management system introduces RFID technology into the existing CFS warehouse management, and automatically collects data in each operation link of the CFS warehouse, such as storage, storage, allocation, shifting, inventory counting, etc. The wireless network coverage is implemented in the warehouse operation area to realize the real-time transmission of forklift and staff scheduling information and operation information. The two work together to ensure the rapid, real-time and accuracy of data collection and processing in all aspects of warehouse management.
System principle
The entire system can be divided into three major components, namely RFID automatic identification system, wireless data transmission system, and back-end warehouse management system.
1) RFID automatic identification system
First, establish the concept of location in the existing CFS warehouse. The so-called storage location is to divide a pallet stacking position in the existing warehouse with the size of a pallet as a unit, install RFID electronic tags on each storage location, and pre-enter it into the system, in the back-end warehouse management system , Using the ID number of the RFID electronic tag as an index, create an electronic file for each location, so that a one-to-one correspondence between the location and the RFID electronic tag is established, and the CFS warehouse with the RFID electronic tag ID number is generated from this Two-dimensional map of the location. The reading and writing of the RFID electronic tags of the warehouse is completed by the forklift driver operating the handheld RFID reader. Then, install RFID electronic tags on the pallets used in this CFS warehouse and enter them into the back-end database to establish a “RFID electronic pallet” database to establish a one-to-one correspondence between RFID electronic tags and pallets. The reading and writing of the RFID electronic label on the pallet is completed by the tally operator operating the handheld RFID reader. When the forklift passes the warehouse entrance and exit, the electronic label on the pallet will be read by the fixed reader, and the controller will send the label data to the back-end warehouse management system to reconfirm the correctness of the pallet and its goods. If it is correct, it will pass smoothly. , The back-end warehouse management system unbinds the outbound pallet from the corresponding location, and if an exception occurs, the forklift is prohibited from passing.
2) Wireless data transmission system
The wireless data transmission network chooses the 802.11b/g protocol (WIFI). The advantage is that the communication protocol is mature, the utilization rate is high, and there are many types of wireless access point (AP) devices supported. Depending on the cost of the enterprise, there is a lot of room for choice. . Set up a wireless data transmission network in the warehouse so that the wireless signal covers the entire warehouse and part of the area outside the warehouse. The wireless network transmission terminal communicates two-way data with the wireless AP to complete the upload of RFID electronic tags and stored data, as well as the issuance of operation instruction data. Then, multiple APs are connected to the server where the back-end warehouse management software is located through a network switch (Ethernet). So as to complete the data interaction between the wireless network AP and the back-end warehouse management system.
3) Back-end warehouse management system
The database software on the PC side monitors and records the events that occur in the warehouse, displays the current location, pallets, and cargo status of the warehouse in real time, and manages and dispatches the forklifts in the warehouse, monitors the various processes that occur in the warehouse, performs operations and generates corresponding Documents.
The overall structure of the system
The CFS intelligent warehouse management system based on RFID technology is mainly composed of tally clerk handheld devices, warehouse entrance and exit gate equipment, warehouse wireless transmission equipment and warehouse management back-end system. It is aimed at different operation processes of goods in and out of the warehouse.
System functions
The CFS intelligent warehouse management system realizes the intelligence, standardization, efficiency and precision of cargo management, which are described as follows.
Informationization: Aiming at the current traditional and backward operation and management methods of CFS warehouses, it is proposed to introduce intelligent RFID technology to fundamentally improve the degree of informatization of the warehouse.
Standardization: In view of the current situation of CFS warehouses with different living conditions, different sizes, and uneven quality, the standardization of warehouse management is proposed to ensure the safety of goods and help establish a corporate image.
Efficient: In view of the slow handwriting of CFS warehouse workers and the input of information on paper into the computer system after the goods are in and out of the warehouse, it is proposed that the warehouse management information is data-based, timely and efficient.
Accuracy: Aiming at the current situation of CFS warehouses using paper as the information carrier, manual input and verification of information, the accuracy of warehouse management is proposed to reduce the error rate and increase corporate profits.
Application effect
Currently, CFS warehouse is an important link in import and export trade. In the entire import and export trade, it is important to consolidate the goods, pack them to the dock and ship, or split the goods of a container into different parts, and then distribute them. effect. With the rapid development of the foreign trade industry today, the efficiency and accuracy of the management of CFS warehouses have been closely linked with the profits of the entire foreign trade industry and the development prospects of the industry.
Using the CFS intelligent warehouse management system based on RFID technology can achieve the following application effects.
1) Shorten warehouse operation time.
2) The system can grasp the incoming and outgoing situation of goods in real time.
3) Instead of manual input of information after the end of the job, the transmission and recording of information is more rapid and accurate.
4) It can realize a two-dimensional plan view or a three-dimensional three-dimensional view of the warehouse, and real-time grasp of the warehouse goods and warehouse usage.
5) Enhance corporate image and increase corporate efficiency.
