RFID Tag Communication Data Compression for Storage Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current RFID tag communication systems face challenges in shortening communication time as the demand for increased storage capacity leads to longer communication times due to the need to transmit larger amounts of data, and existing methods do not effectively compress data for faster transmission.
Innovation Solution
A tag communication apparatus that compresses at least part of the transmit data before transmission to the RFID tag, using a data compression unit, and includes a space information producing unit to manage storage space, an empty space determining unit, and a space shortage information transmission unit to optimize data transmission and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the storage capacity of the RFID tag is increased to meet the demand for wider application, then the information storage capability is improved, but the communication time between the tag communication apparatus and the RFID tag is lengthened
Solution Approach 1:
The patent applies preliminary action by compressing the data before transmission to the RFID tag. The tag communication apparatus performs data compression on the information to be stored, reducing the data size before it is transmitted to the tag. This preliminary compression action allows more information to be stored in the tag without increasing communication time, as the compressed data occupies less transmission bandwidth.
2Quantity of substance
If the information amount in communication is increased to store more data, then the storage capacity is improved, but the communication time is lengthened
Solution Approach 1:
The patent applies parameter changes by transforming the data into a compressed format, changing the physical parameter of data size. The compression process reduces the volume of information that needs to be transmitted, allowing more logical information to be communicated within the same time frame. This parameter transformation resolves the contradiction between information amount and communication time.
3Loss of time
If the data is transmitted without compression to maintain communication speed, then the communication time is reduced, but the storage capacity is insufficient
Solution Approach 1:
The patent performs the compression action beforehand, before the transmission process begins. By pre-compressing the data in the tag communication apparatus, the system ensures that the compressed data is ready for immediate transmission, maintaining communication speed while enabling increased storage capacity in the RFID tag.
