Method and apparatus for routing data in automatic identification system

Abstract

A system for routing data in an automatic identification system includes an event management system (EMS), a real-time in-memory data structure (RIED) coupled to the EMS, the RIED for storing event information gathered by the EMS and a task management system (TMS) for ensuring that the RIED is updated by one transaction at a time. With this particular arrangement, a system for managing a large number of real-time events is provided. In one embodiment, the control system can be provided in a distributed hierarchical arrangement. The EMS of each control system can include filters which limit the amount of information provided to the next level in the hierarchy. In this manner the hierarchical control system network acts as a high volume data collector and processor. In some embodiments a level of the hierarchy can be removed spatially and / or temporally from an adjacent level in the hierarchy. This approach results in an intelligent network and also lends itself to scalability. By including optional filters and queues in the EMS, the EMS can be configured as desired.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of provisional application No. 60 / 444,090 filed Jan. 31, 2003, the disclosure of which is hereby incorporated by reference.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH [0002] Not Applicable. FIELD OF THE INVENTION [0003] The present invention relates generally to a network service and related apparatus and more particularly to a service for identifying objects based upon a unique code associated with that object. BACKGROUND OF THE INVENTION [0004] As is known in the art, the ability to uniquely identify items, devices, and services (collectively called objects) is essential for many applications including but not limited to security access control, supply chain management and communications. The inability to uniquely identify every object of interest renders many of these applications less effective than is generally desired. One component for unique identification is the association of a unique i...

Benefits of technology

[0006] In accordance with the present invention, a system for routing data in an automatic identification system includes an event management system (EMS), a real-time in-memory data structure (RIED) coupled to the EMS, the RIED for storing event information gathered by the EMS and a task management system (TMS) for ensuring that the RIED is updated by one transaction at a time. With this particular arrangement, a system for managing a large number of real-time events is provided. In one embodiment, the control system can be provided in a distributed hierarchical arrangement. The EMS of each control system can include filters which limit the amount of information provided to the next level in the hierarchy. In this manner the hierarchical control system network acts as a high volume data collector and processor. In some embodiments a level of the hierarchy can be removed spatially and / or temporally from an adjacent level in the hierarchy. This approach results in an intelligent network and also lends itself to scalability. By including optional filters and queues in the EMS, the EMS can be configured as desired.

Problems solved by technology

The inability to uniquely identify every object of interest renders many of these applications less effective than is generally desired.

It has, therefore, been recognized that managing and moving all of this data is a difficult problem and one that must be addressed in an RF ID network.
