Vehicle RDS/RDS2 Data Broadcasting Relay for FM Null Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio data systems (RDS/RDS2) face limitations in data transmission capacity and fail to receive additional data in areas where FM broadcasts are not receivable, leading to restrictions in displaying related information on GUI screens.
Innovation Solution
A vehicle-based system that transmits and receives RDS/RDS2 data in null points by storing and encoding the data for transmission to other vehicles, using a transceiver, display, memory, and controller to manage communication status and data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RDS/RDS2 data is transmitted using FM analog broadcasting, then data broadcasting service is provided, but reception fails in areas where FM broadcasting is not receivable (null sections)
Solution Approach 1:
The patent introduces a peer vehicle as an intermediary node that receives RDS/RDS2 data from the broadcast signal and re-transmits it to other vehicles in null sections. This mediator approach allows data to be relayed through vehicles that are themselves receiving the signal, solving the coverage gap problem in areas where direct FM reception is unavailable.
Solution Approach 2:
The patent enables vehicles to serve dual functions: both receiving RDS/RDS2 data from the broadcast signal and simultaneously acting as transmitters to relay this data to other vehicles. This multi-functionality transforms ordinary vehicles into mobile relay nodes, expanding service availability beyond traditional FM reception areas.
2Quantity of substance
If additional data is added to analog broadcasting using RDS/RDS2, then data capacity is increased, but the system cannot operate in areas with poor FM reception
Solution Approach 1:
The patent implements preliminary action by having vehicles store received RDS/RDS2 data in memory before transmission. This allows the system to capture and hold data when reception is available, then transmit it later when the vehicle enters null sections, ensuring continuous data availability independent of real-time signal strength.
Solution Approach 2:
The patent ensures continuity of useful action by implementing continuous monitoring of communication status and persistent storage of RDS/RDS2 data. The system maintains operational continuity by relaying data through multiple vehicles, ensuring that the data broadcasting service never stops even when direct reception is unavailable.
3Adaptability or versatility
If RDS/RDS2 data is stored and transmitted by vehicles, then service availability in null sections is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service by enabling vehicles to autonomously monitor their own communication status, store received data in their memory, and transmit it to other vehicles without external control. Each vehicle independently manages its own data relay function, simplifying the overall system architecture while expanding service coverage.
Solution Approach 2:
The patent merges the functions of data reception, storage, and transmission into a single integrated system within each vehicle. By combining these functions and utilizing existing vehicle components (transceiver, memory, controller), the system achieves enhanced service availability without proportionally increasing device complexity.
