Vehicular Remote Antenna Unit Reprogramming via Communication Cable
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular communication systems face inefficiencies in reconfiguring remote antenna units, requiring complex replacement processes when changes such as supporting new frequency bands are necessary, often necessitating disassembly and reassembly.
Innovation Solution
The system allows for remote reprogramming of the remote antenna unit via the same communication cable used for RF signals, using a predetermined protocol to transmit flash programming data, enabling the remote antenna unit to self-program without disassembly, and potentially using a dedicated subcarrier frequency for reprogramming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the remote antenna unit is unmounted and replaced to support a new frequency band, then the system can support new frequency bands, but the complexity of the replacement process increases and labor time is consumed
Solution Approach 1:
The patent applies parameter changes by modifying the software configuration parameters of the remote antenna unit to support new frequency bands. Instead of replacing the entire hardware unit, the system transmits new configuration parameters via the existing communication cable, allowing the antenna unit to adapt to different frequency bands through software reprogramming. This resolves the contradiction by maintaining frequency band adaptability while eliminating the complex replacement process.
Solution Approach 2:
The patent uses copying by transmitting a copy of the updated configuration data or firmware through the existing communication cable. Rather than physically replacing the antenna unit, the system copies the necessary software updates and configuration parameters to the remote antenna unit, enabling it to support new frequency bands. This approach maintains adaptability while avoiding the complexity of physical replacement.
2Adaptability or versatility
If the remote antenna unit is unmounted and changes are made to the unmounted unit, then configuration changes can be implemented, but the time required for disassembly and reassembly increases
Solution Approach 1:
The patent applies self-service by enabling the remote antenna unit to reprogram itself using the existing communication cable. The unit receives configuration updates or firmware changes through its normal communication interface and autonomously applies these changes without requiring physical disassembly or reassembly. This resolves the contradiction by maintaining configuration change capability while eliminating the time-consuming manual intervention required for mounting and dismounting the unit.
Solution Approach 2:
The patent applies universality by using the existing communication cable for multiple purposes: both for normal RF signal transmission and for transmitting configuration updates. This multi-functional use of the communication interface allows the system to implement configuration changes without requiring separate programming interfaces or physical access to the antenna unit, thereby eliminating disassembly time while maintaining full configuration flexibility.
3Ease of operation
If a dedicated programming interface is added to the remote antenna unit, then reprogramming capability is improved, but the device complexity and hardware requirements increase
Solution Approach 1:
The patent applies universality by making the existing communication cable serve dual purposes: transmitting both RF signals and programming data. The system uses the same communication interface and cable infrastructure for both operational signals and configuration updates, eliminating the need for dedicated programming hardware. This resolves the contradiction by providing full reprogramming capability while avoiding any increase in hardware complexity or additional cable requirements.
Solution Approach 2:
The patent applies merging by combining the programming function with the existing communication function. Instead of separating programming operations into a distinct hardware interface, the system integrates configuration updates into the normal communication protocol, allowing both RF signal transmission and programming operations to occur through the same cable and interface. This approach provides ease of operation while maintaining simple hardware architecture.
