environment and characteristic, place heaps brand
with unique RFID tags in each region, and then bind
stack cards numbers and RFID tag in the
management system.
2) Assemble RFID reader, license plate
identification equipment, land coils and infrared
sensing equipment in the original land sino-scale
system of bulk cargo ports, forming intelligent
weighing system. Land coils and infrared sensing
equipment perceive whether the trucks are on the
load meter equipment, which is in charge of starting
automatically RFID reader, camera gun and sino-
scale to gather and store the RFID card information,
license plate information and the weight of delivery
vehicles.
3.2 Unloading and Warehousing
Process Optimization
This process is unloading freight from ship to shore
and then transported to the yard. After the
optimization process can be divided into three
specific areas.
1) Before unloading and storing the freight, the
port planners in accordance with the actual needs to
development of "freight storage plan", entry the
freight information in the management system, plan
the number of heap-bit and bind the freight with a
RFID tag.
2) When the freight into the storage, the
warehouse staff read the "freight storage plan" with
PDA, and guide workers unload the freight to the
specified heap-bit and the RFID tags into the stack
bit.
3) After the storage, the warehouse staff should
confirm the unloading ship plan and automatically
generates records storage. .If the actual switch stack
is different from the plan stack, they should notify
the planners to modify the information.
3.3 Out of Storage Process Optimization
The out of storage process refers to loading freight
from the yard to the trucks, and then transports them
through the port access control systems to outside
port. Optimized based on RFID technology, the
specific process includes four parts.
1) Before the cargo owner delivery the freight,
port planners, in accordance with actual needs of this
business and the conditions of stockpiling, develop
bill of lading and more than one RFID cards to bind
RFID cards already in the system, referred to as the
delivery of the certificate cargo owners.
2) Before out storage operations, the port
planners in accordance with actual needs of this
business develop out “out storage plan” and input
information of delivery of freight in the management
system and the RFID number.
3) Stack delivery: The warehouse staff reads
RFID number of loading freight trucks by the PDA
machine, compares with the freight RFID and out of
storage plan, and transmits it through the wireless
network to the back-end system to guide loading
operations.
4) When the truck weighing, the smart weighing
system reads the information from RFID tag which
is bound on the truck. And then the management
system would record the car weighing and produce
the out storage weighing after through the heavy
pound.
3.4 Switch Stack Process Optimization
Switch stack process means that in view of the needs
of business, location of commercial vehicles changes
within storage yard of the port. Optimized based on
RFID technology, the specific process includes two
parts.
1) Before switch stack process, port planners in
accordance with actual needs of this business
develop "switch stack plan", which means they entry
the freight in the information system. The
information of freight includes RFID tag number,
former stack position and planned switch position.
2) When switch stack process starts, according
with the requirements of "switch stack plan",
warehouse staff guide the workers in the freight
transferred to the planned stack position .After that,
warehouse staff confirm the “switch stack plan” with
PDA and then automatically switch to stack records.
If the actual switch stack is different from the plan
stack, they should notify the planners to modify the
information.
Through the above analysis of three processes, it
is certainly that, after the application of RFID, the
import business process has been more
programmatic and management more standardized.
It also lays the foundation to the realization of the
port of handling automation and the use of
transparent in terminal.
