RFID Reader Multicast Configuration via Host Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing and configuring multiple RFID readers becomes burdensome as the number of readers under a host system grows, requiring individual IP address management and configuration commands.
Innovation Solution
Assigning a multicast address to each reader, allowing a host server to send a single multicast message for configuring or managing polling operations across multiple readers, using multicasting protocols like TCP/IP to streamline management and configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual IP address management and configuration commands are used for each RFID reader, then precise control and configuration of each reader is achieved, but the administrative burden and complexity increase significantly as the number of readers grows
Solution Approach 1:
The patent introduces a multicast address as an intermediary that represents a group of RFID readers. Instead of directly managing individual IP addresses of each reader, the host system uses the multicast address as a mediator to send configuration commands to multiple readers simultaneously. This reduces the administrative burden while maintaining precise control over reader configurations.
Solution Approach 2:
The patent combines multiple individual reader management operations into a single multicast message transmission. By merging the configuration commands for multiple readers into one unified communication channel (multicast group), the system achieves efficient bulk management of RFID readers without the overhead of individual command transmissions to each reader.
2Productivity
If individual configuration commands are sent to each RFID reader, then precise configuration control is maintained, but the time and resources required for managing large numbers of readers increase
Solution Approach 1:
The patent merges multiple individual configuration operations into a single multicast message that can be received and processed by multiple readers simultaneously. This combining of operations dramatically reduces the time required to configure large numbers of readers compared to sending individual commands to each reader sequentially.
Solution Approach 2:
The system performs preliminary setup by assigning multicast addresses to groups of readers before actual configuration operations. This preliminary grouping action enables subsequent bulk configuration operations to proceed efficiently without requiring individual reader identification and addressing during the actual configuration process.

AI summary
A host server may optimize configurations of a set of readers under its control. The server assigns a multicast address to each reader in the set. Once connected, the server sends a multicast message to each reader assigned to the multicast address or to each reader within a given address range. Information in the multicast message is used for configuring or managing polling operations of each reader assigned to the multicast address or each reader within the given address range.
