V2X Warning Device Using Distance Velocity Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current V2X NB-IOT communication systems primarily focus on determining potential traffic accidents for individual devices rather than preventing accidents involving adjacent vehicles or on-road devices, leading to inefficient accident prevention.
Innovation Solution
An instant traffic condition warning method and device that utilize a controller to receive vehicle distance and velocity values, triggering a warning signal when the distance is below a threshold and velocity exceeds a set limit, using sensors, a warning element, and communication assembly to alert drivers or pedestrians of potential collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the system only determines potential traffic accidents for individual devices, then the device complexity is reduced, but the accident prevention effectiveness deteriorates
Solution Approach 1:
The system segments the monitoring scope into two levels: individual device monitoring (basic function) and adjacent device monitoring (enhanced function). The controller divides the monitoring task by identifying the device itself and adjacent devices separately, applying different monitoring depths to each segment, thus reducing overall system complexity while improving prevention effectiveness through targeted monitoring.
Solution Approach 2:
The system transitions from single-dimension (individual device) monitoring to multi-dimension monitoring by adding the spatial dimension of adjacent devices. The controller determines not only the device's own status but also the status of devices in surrounding spatial positions, creating a multi-dimensional monitoring framework that enhances accident prevention without proportionally increasing complexity.
2Use of energy by moving object
If the system monitors only individual device conditions, then the information processing load is reduced, but the traffic safety improvement is insufficient
Solution Approach 1:
The system applies local quality by differentiating the monitoring intensity for different spatial locations. The controller focuses detailed monitoring resources on adjacent devices that pose higher collision risks, while using lighter monitoring for individual device status. This localized quality enhancement improves traffic safety without proportionally increasing information processing load across the entire system.
3Reliability
If the system determines potential accidents for adjacent vehicles and on-road devices, then the accident prevention effectiveness is improved, but the device complexity increases
Solution Approach 1:
The system performs preliminary action by pre-establishing the adjacent device identification criteria and monitoring thresholds before actual accident prevention is needed. The controller is pre-programmed with the logic to identify adjacent devices and determine their status, so that when potential accidents are detected, the system can immediately respond without complex real-time decision-making, thus improving effectiveness while controlling complexity.

AI summary
An instant traffic condition warning method comprises the following steps. A controller receives a vehicle distance value and a vehicle velocity value, and the controller determines whether the vehicle distance value is less than a distance threshold. When the vehicle distance value is less than the distance threshold, the controller determines whether the vehicle velocity value is larger than a velocity threshold. When the vehicle velocity value is larger than the velocity threshold, a warning element generates a warning signal.
