RFID Data Correlation With Subscription-Based Bandwidth Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The collection and transmission of large amounts of data from various sources such as RFID readers, video cameras, and environmental sensors result in inefficient bandwidth usage and increased costs due to unnecessary data transfer.
Innovation Solution
A method for correlating and aggregating data at the site of collection, reducing it to only the data requested by applications, and transmitting this data efficiently to remote locations using a server computer with middleware and data set providers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all data from RFID readers, video cameras, and environmental sensors is collected and transmitted, then complete information about objects is available, but bandwidth usage increases and transmission costs increase
Solution Approach 1:
The patent extracts only the specific data elements requested by applications from the complete data set collected by sensors and RFID readers. The data set provider filters and transmits only the relevant portions of data needed by each application, eliminating unnecessary data transmission while maintaining information completeness for requested parameters.
Solution Approach 2:
The patent implements local quality by customizing data sets for each application based on its specific requirements. Each application receives a tailored data set containing only the data elements it needs, rather than a uniform complete data set. This allows different applications to receive different qualities and types of data appropriate to their local needs.
2Loss of information
If all data from multiple sources is transmitted to remote locations, then comprehensive data is available at remote sites, but data transfer costs increase
Solution Approach 1:
The data set provider extracts and transmits only the specific data elements requested by each application. Instead of transmitting complete data sets from all sources to all remote locations, the system identifies and transmits only the necessary portions, reducing data transfer costs while maintaining data availability for requested information.
Solution Approach 2:
The patent inverts the traditional approach by having applications specify what data they need rather than systematically transmitting all available data. The data set provider receives subscription requests that define the required data content and format, then constructs and transmits customized data sets containing only those elements, reversing the conventional push model to a pull model.
3Ease of operation
If data is processed and formatted at the data set provider before transmission, then applications receive ready-to-use data, but processing complexity increases
Solution Approach 1:
The patent applies preliminary action by performing data collection, filtering, formatting, and correlation operations at the data set provider before transmission. The system pre-processes data from multiple sources, correlates RFID tag data with sensor data, converts data to requested formats, and assembles complete data sets in advance, so that applications receive ready-to-use data without needing to perform complex processing themselves.
4Loss of information
If customized data sets are provided to different applications based on their requirements, then data relevance improves, but system complexity increases
Solution Approach 1:
The patent implements local quality by providing customized data sets tailored to each application's specific requirements. Each application receives data with the appropriate content, format, and level of detail suited to its local needs. The system manages this complexity through a standardized subscription interface that allows applications to specify their requirements without increasing overall system complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach minimizes data transfer costs and bandwidth requirements by ensuring only relevant data is transmitted, improving processing efficiency and reducing unnecessary data movement.
Implementation Method 1
receiving tag data from a radio frequency identification (RFID) reader, the tag data read from an RFID tag attached to an object
Data Source
AI summary
A method is disclosed for providing, in a server computer, a data set to a subscriber. The method includes receiving a first subscription request from a subscriber specifying first data content and format for members of a first data set, sending a second subscription request to a data set provider specifying a second data content and format for members of a second data set, receiving RFID reader locations, receiving a second data set member having RFID tag data read by the RFID readers, generating an object location based on the RFID tag data read and the RFID reader locations, receiving real-time data relating to the object; converting the real-time data to converted real-time data having the first data set data format; generating a first data set member from the object location, the tag data, and the converted real-time data, and sending the first data set member to the subscriber.
