a combination of modern production methods, modern management methods, and
modern information technology in the logistics field. The embodiment. 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 for short) 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 warehousing,
outgoing, allocation, shifting, and inventory counting. 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.
The whole 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 storage location 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 802.11b/g protocol (WIFI).
The advantage is that the communication protocol is mature, the utilization rate
is high, and the types of wireless access point (AP) devices supported are wide.
. 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) Backstage warehouse management system
The PC-side database software monitors and records the events that occur in
the warehouse, displays the current location, pallets, and cargo status of the
warehouse in real time, 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.
Informatization: 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 build a corporate image.
Efficient: Aiming at the current situation that CFS warehouse workers are
slow to write operation orders and input the 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
information carrier, manual input and checking information, the warehouse
management accuracy is proposed to reduce the error rate and increase corporate
profits.
Application effect
At present, 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. Today, with the rapid development of
the foreign trade industry, 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 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) Two-dimensional plan view or three-dimensional three-dimensional view of
the warehouse can be realized, and real-time knowledge of warehouse goods and
warehouse usage.
5) Enhance corporate image and increase corporate efficiency.
