Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In transportation safety systems, there is a lack of effective solutions for managing sensor failures, particularly in IoT-based M2M communication systems, where a malfunctioning sensor's function cannot be efficiently taken over by another sensor, leading to potential safety and operational inefficiencies.
Innovation Solution
A method and apparatus that enable a vehicle to monitor the state of a first sensor and determine whether a second sensor, either on the same vehicle or an adjacent vehicle, can take over the function of the malfunctioning sensor, allowing for seamless reporting and data reception, thereby ensuring continuous operation and improved safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sensor malfunction occurs in an IoT-based M2M communication system, then the system experiences operational inefficiency and potential safety issues, but the malfunctioning sensor's function cannot be efficiently taken over by another sensor
Solution Approach 1:
The patent introduces a management server as an intermediary that coordinates sensor function takeover between vehicles. When a sensor malfunctions, the management server receives failure information, identifies a suitable replacement sensor from another vehicle, and manages the data transfer process, enabling reliable function continuity without direct peer-to-peer coordination complexity
Solution Approach 2:
The patent enables sensors from different vehicles to perform the same function through the management server coordination. A sensor in one vehicle can take over the function of a malfunctioning sensor in another vehicle, creating a universal sensor resource pool that improves both reliability and operational efficiency
2Reliability
If sensor failure management is implemented in transportation safety systems, then system reliability improves, but device complexity increases due to additional monitoring and coordination mechanisms
Solution Approach 1:
The management server acts as a centralized intermediary that simplifies the overall system architecture. Instead of implementing complex distributed monitoring and coordination protocols across multiple vehicles, the management server centralizes the failure detection, replacement sensor identification, and data routing functions, reducing device complexity while maintaining reliability
3Reliability
If a second sensor from another vehicle is used to take over the function of a malfunctioning sensor, then system reliability improves, but communication and data exchange complexity increases
Solution Approach 1:
The management server serves as a communication intermediary that simplifies data exchange between vehicles. Instead of implementing direct peer-to-peer communication protocols between sensor-equipped vehicles, all communication regarding sensor status, failure reporting, and data transfer is routed through the management server, reducing communication complexity while enabling reliable sensor replacement

AI summary
The present invention may provide a method of managing, by a vehicle, a sensor. Herein, a method of managing, by a vehicle, a sensor may include: monitoring state information of a first sensor of a first vehicle; when the first sensor is abnormal, determining whether or not a second sensor performs the function of the first sensor; when the second sensor performs the function of the first sensor, reporting information representing that second sensor performs the function of the first sensor; and receiving sensing data from the second sensor.
