Server-Based Tag Reader Transmission Regulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments with multiple RFID tag readers sending frequent transmission reports, the spectral bandwidth and battery power of these devices are often exhausted more than necessary, leading to inefficiencies and potential system overload.
Innovation Solution
A server-based system compares transmission reports from mobile tag readers to predefined reporting rules, instructing selected readers to reduce or halt transmission reports based on location, frequency, or threshold criteria, thereby optimizing data transmission and conserving resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple tag readers send frequent transmission reports, then data coverage and monitoring accuracy are improved, but spectral bandwidth and battery power are exhausted more than necessary
Solution Approach 1:
The system dynamically adjusts the reporting frequency of tag readers based on real-time conditions. When multiple readers are detecting the same tag in overlapping coverage areas, the server instructs some readers to reduce or suspend reporting, while maintaining monitoring coverage through other readers. This dynamic adjustment resolves the contradiction by adapting reporting behavior to actual system needs rather than using fixed frequent reporting.
Solution Approach 2:
The server receives transmission reports from multiple tag readers and analyzes the data to determine which readers are reporting redundant information. Based on this feedback, the server sends instructions back to specific readers to adjust their reporting frequency. This closed-loop feedback mechanism ensures monitoring accuracy is maintained while preventing unnecessary energy consumption from redundant reports.
2Measurement precision
If multiple tag readers send frequent transmission reports, then data coverage and monitoring accuracy are improved, but spectral bandwidth is exhausted more than necessary
Solution Approach 1:
The system extracts and identifies redundant transmission reports by analyzing data from multiple readers. When the server determines that a tag is already being detected by another reader in the same or overlapping coverage area, it extracts (removes) the redundant report from the transmission stream. This prevents unnecessary spectral bandwidth consumption while maintaining complete monitoring coverage.
Solution Approach 2:
Instead of all readers continuously reporting at full frequency, the system implements partial action where only necessary readers report at necessary frequencies. The server selectively activates reporting from specific readers based on current system needs, ensuring adequate monitoring coverage without the excessive bandwidth consumption that would result from all readers reporting simultaneously at maximum frequency.
3Use of energy by moving object
If transmission reports are reduced, then spectral bandwidth and battery power are conserved, but data coverage may be compromised
Solution Approach 1:
The server continuously monitors transmission reports and system state to determine when reducing reader reporting frequency would compromise data coverage. By analyzing the actual detection data and coverage overlap information, the server provides feedback to maintain reporting from sufficient readers to ensure complete coverage, while allowing other readers to reduce activity and conserve battery power.
Solution Approach 2:
The system merges the monitoring function across multiple readers, where the collective coverage of several readers ensures complete data coverage even if individual readers reduce their reporting frequency. By coordinating readers to cover different spatial or temporal segments, the system maintains overall reliability while allowing individual energy conservation.

AI summary
A server may compare transmission reports received from mobile tag readers to a reporting rule. Each transmission report includes a reported location of the respective mobile tag reader when the respective mobile tag reader received a wireless transmission from a tag. Responsive to a determination that the transmission reports satisfy the reporting rule, an instruction may be generated that instructs a mobile tag reader to reduce how often tag transmission reports are sent to the server. Mobile tag readers may be selected to receive the instruction based on the reported location. The instruction may be sent to the selected mobile tag readers. The sending of transmission reports by tag readers may be reduced.
