Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In intelligent vehicles, radio frequency components are prone to damage during emergencies like collisions or fires, leading to failed emergency calls and delayed rescue due to non-functional communication modules.
Innovation Solution
A method and apparatus that determine a radio frequency path by scanning pre-configured identifiers to identify functional components, switching to alternative paths when faults are detected, ensuring data transmission through backup paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system uses a single radio frequency path for emergency communication, then the device complexity is reduced, but the reliability deteriorates because any component failure along that path causes communication failure
Solution Approach 1:
The radio frequency communication system is segmented into multiple independent paths (first radio frequency path, second radio frequency path, etc.), each with its own set of radio frequency components. This segmentation allows the system to isolate failures to specific segments while maintaining functionality through alternative segments, thereby improving reliability without requiring a completely redundant system.
Solution Approach 2:
The system performs preliminary detection of radio frequency components along the first path before attempting communication. When a fault is detected, the system has already identified the failure and can immediately switch to a pre-configured alternative path without delay, ensuring continuous communication capability during emergencies.
2Reliability
If the system scans and detects all radio frequency components to ensure normal communication, then the reliability is improved, but the loss of time increases during emergency situations
Solution Approach 1:
The system performs preliminary scanning and fault detection of radio frequency components along the first path in advance, before an emergency communication request is made. This preliminary action ensures that when an emergency occurs, the system already knows the status of the primary path and can immediately switch to an alternative path if needed, minimizing communication delay.
Solution Approach 2:
The system continuously monitors the status of radio frequency components and provides feedback on their operational state. When a fault is detected, the feedback mechanism triggers automatic switching to an alternative path, ensuring that the system responds quickly to failures without requiring manual intervention or extensive re-detection during emergencies.
3Reliability
If the system implements multiple pre-configured radio frequency paths for fault tolerance, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The multiple radio frequency paths are segmented into distinct, independently configurable units (first path, second path, etc.), each with its own set of radio frequency components. This modular segmentation allows the system to implement fault tolerance through multiple paths while managing complexity by keeping each segment relatively simple and independent.
Solution Approach 2:
The alternative radio frequency paths are designed with universal functionality, meaning they can serve multiple purposes: as backup paths for fault tolerance, as primary paths if the first path fails, and as configurable options for different communication scenarios. This multi-functionality reduces the need for specialized components for each path, thereby managing overall system complexity.

AI summary
Disclosed are a method and an apparatus for determining a radio frequency path, a device, and a storage medium. The method includes: acquiring a first radio frequency path identifier and scanning radio frequency components corresponding to the first radio frequency path identifier; when it is determined that there is no faulty component among the radio frequency components corresponding to the first radio frequency path identifier, taking the first radio frequency path identifier as a target radio frequency path identifier; when it is determined that there is a faulty component among the radio frequency components corresponding to the first radio frequency path identifier, selecting a second radio frequency path identifier from a plurality of pre-configured radio frequency path identifiers; and scanning a radio frequency component corresponding to the second radio frequency path identifier, and when it is determined that there is no faulty component among the radio frequency components corresponding to the second radio frequency path identifier, taking the second radio frequency path identifier as a target radio frequency path identifier.
