Integration with Rifidi
The RFID reader module is emulated using Rifidi.It is important to understand
that this virtual environment allows to use the real protocol of the RFID tag and
reader.As said,Rifidi emulates the reader/client interface of actual RFID readers;
a client communicates with the Rifidi reader in the same way that it would communicate
with a real reader.Therefore,the virtual module can be substituted with
a physical module which manages the physical RFID objects and the whole system
will still work.
In our tests,we have considered four RFID readers AlienALR9008,which have
the characteristics to interact with other objects,such as push-arms.We have also
created some RFID tags which are represented as boxes in the 3D environment.
These boxes with tags are moved in the 3D scenario proceeding on conveyors
with the help of push-arms.The RFID readers are situated at different locations
that are passed by the boxes to recreate different moments:i) the customer gets
one or more items from the shelf,ii) the customer goes to the changing room,
iii) the customer exits from the changing room,and iv) the customer puts the
items back on the shelf.
The operations with Rifidi can be divided into two parts.In the first one,we
start the connections to a shelf reader from the console.We suppose,in fact,the
existence of a central computer which will manage these readers and will set the
connections.In a simple way,the software part about the shelf reader sets as busy
the taken garment.If the garment is put again on the shelf,it will be set as free in
the database.We can write the following command to start a reader connection
