RFID(Radio Frequency Identification)
Consists of reader and tag wireless non-contact use of radio-
frequency electromagnetic fields to transfer data, for the purposes of identifying and tracking tags attached to objects
Used in many industries, such as transportation, health care, education

RFID middleware
It coordinates RFID readers, process the vast amount of captured data.
It handles the communication between readers and application software.

Problems
Most of the current existing RFID middleware are sophisticated and expensive
> Simplify in structure and reduce in scale to suit manufacturing scenarios It needs to be more agile and
responsive to the modern changing market
> Design it to be flexible, modularized, rather than full-featured and sophisticated

Gateway Operation manager
manage gateway operation system provide user interface for the
configurations of gateway and connected devices
contains several built-in applications allows user to add other new
application
16/31
100062214 王怡儒 /100062372 簡均容 /100034048 王品淳
Device management tool
provides a set of interfaces to configure the connected RFID/Auto-ID devices
17/31
100062214 王怡儒 /100062372 簡均容 /100034048 王品淳
Device management tool
devices are able to be detected automatically and managed
allows user to check all information about each connected device
provide device diagnosis functions

100062214 王怡儒 /100062372 簡均容 /100034048 王品淳
Workflow management
implement manufacturing processes and its corresponding data basic component : activities ,
business logic , smart agents setup by load existing workflow
descriptions in XML

100062214 王怡儒 /100062372 簡均容 /100034048 王品淳
Reader service control
access RFID readers directly at some situations web service mode : implemented and
published for back-end applications, which include tag reading and writing
messaging mode : domain applications interact with smart agents through AIS to exchange information between applications and software agents

Application information service a communication protocol for
applications and agents at gateway operating system
provide a way for applications to utilize the Auto-ID device infrastructure
23/31
100062214 王怡儒 /100062372 簡均容 /100034048 王品淳
Application information service Design principles:
A. simple, lightweight and efficient B. in an open and universal format C. be extensible and easy to maintain
