| The 411 Eureka Tagging System is used for identification
of the Parcelforce fleet of delivery vehicles at their National
and International depot in Coventry, England,
and can be effectively employed to automatically identify both
incoming and outgoing vehicles and communicate data between
one of seven security points and the Host system controlling
the Parcelforce vehicle scheduling system (VCS). VCS was provided
by the Danish sorting systems supplier, Crisplant a/s. |
 |
 |
The benefits to Parcelforce are that vehicles no longer need
to be recorded manually at gatehouses which took an average
of 15 minutes per delivery. By reducing the entry time, they
have massively improved the efficiency and trailer management
on site. In conjunction with a fully automated sorting system
they are now able to benefit from an integrated delivery, sorting
and despatch system, improving both delivery times and efficiency. |
System Operation
An Automatic Vehicle Identification System using the Eureka
411 Tagging system has been installed at two entrances and one
exit to the International Hub as well as two entrances and two
exits to the National Hub. 2,250 411 Tags were fitted to tractors,
trailers and rigid vehicles at several depots throughout the
UK. Whilst each 411 Tag can be read at high speeds, it is limited
by the fact that there are security barriers on the entrances
and exits to the Parcelforce site. |
|
|
| The
main benefits of the 411 Tagging System and VCS are: |
|
 |
Vehicles no longer need
to be recorded manually at gatehouses |
|
|
Pre-scheduled vehicles
and pre-advised vehicles are automatically registered and given
access to the site without gatehouse intervention |
|
|
Vehicle movements are
optimised to maximum efficiency and it is estimated that some
105 hours are saved per day |
|
|
Due to the complexity
and size of the site only automated systems such as the Eureka
Tagging System and VCS can be effective |
|
|
Massive improvements
in on-site trailer management |
|
|
Read/Write Tags can store
Tractor, Trailer and Rigid vehicle numbers as well as MOT and
service information |
|
|
Reduced delays in unloading
trailers at loading bays |
|
|
Clearer, faster and more
accurate production of documentation on delivery information
for drivers |
|
|
Low Frequency operation
of Tagging System allows effective reading through most obstructing
materials. |
|
|
A rugged system which
permits easy installation and maintenance, providing good resilience
to physical damage |
| The Eureka 411 Tag is a high performance radio-frequency
read-write identification device for use in a wide variety of
data collection and identification applications. Up to 115 alpha-numeric
characters may be read from or written to the tag at a range
of up to 1 metre from the standard road loop antenna. The antenna
is connected to a Eureka Decoder which controls and monitors
communications with both the tag and the user's equipment. |
|
 |
|
The 411 Tag operates as a miniature radio frequency transponder.
It is normally in a quiescent state, but when it comes within
range of the radio frequency field produced by the interrogating
antenna, it is activated and transmits its data back to the
antenna. The radio frequency communications to and from the
tag utilise low frequency inductive coupling, and can therefore
function through most non-conducting materials, allowing tag
operation in very difficult or harsh environments. |
|
| Special techniques are used to allow several tags
within the same interrogating field to be identified. A long-life
lithium battery maintains the tag's data memory, and provides
the small amount of power needed to transmit data from the tag.
Because of this the tag is referred to as an 'active transponder'. |
| Summary
of Tag Features |
|
|
Multiple
Readings
Several 411 Tags simultaneously in the interrogation field may
all be identified. |
|
|
High
Speed Data Transmissions
The Tag transmits at a rate of 1,000 characters per second,
providing high speed performance |
|
|
Reliable
Operation through Materials in Harsh Environments
The use of inductive coupling allows effective reading in difficult
circumstances and through a variety of materials |
|
|
The
Same Antenna that Reads the Tag also Writes to the Tag
A common read/write antenna simplifies installations and permits
optimal field position |
