Warning System for Approaching Object Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional warning systems for detecting approaching objects often misidentify non-threatening objects as dangerous, leading to unnecessary fear and panic, and fail to detect approaching objects when there are no vehicles or people in the control area but animals or objects heading towards it.
Innovation Solution
A warning system comprising a detection unit, storage unit, and processing unit that analyzes the moving path of an approaching object within a defined warning area and buffering area, sending a warning signal only when the object consistently moves into the warning area and meets specific confirmation conditions, such as a predetermined count value or time to collision, to prevent false alarms and ensure accurate threat assessment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional detection systems trigger alarms when objects enter a predetermined range, then detection sensitivity is improved, but false alarm rate increases
Solution Approach 1:
The system establishes a buffering area as a preliminary detection zone before the actual warning area. When objects enter the buffering area, the system performs preliminary analysis of their movement trajectories and activates confirmation condition calculations, preparing for potential warning signals before objects reach the critical warning area.
Solution Approach 2:
The system continuously monitors object movement paths and provides feedback by comparing actual trajectories against the buffering area boundaries. This feedback mechanism allows the system to confirm whether objects are truly approaching the warning area or merely passing by, enabling dynamic adjustment of alarm triggering based on confirmed movement patterns.
2Device complexity
If conventional image detection systems monitor only the control area, then system complexity is reduced, but detection capability for approaching objects is insufficient
Solution Approach 1:
The detection space is segmented into two distinct functional zones: a buffering area for preliminary detection and trajectory analysis, and a warning area for confirmed threat detection. This segmentation allows the system to process objects at different stages of approach with appropriate computational resources, improving overall detection capability without proportionally increasing complexity.
Solution Approach 2:
The system performs preliminary detection and trajectory analysis in the buffering area before objects reach the warning area. This preliminary action enables the system to pre-process movement data, identify potential threats early, and prepare confirmation calculations, thereby enhancing detection capability while maintaining manageable system complexity through staged processing.

AI summary
A warning system for detecting approaching object and method thereof are provided. A detection unit detects a moving path of the approaching object; a storage unit stores a warning information including the warning area and the confirmation condition; and a processing unit receives the detection signal provided by the detection unit to acquire the current moving path of the approaching object. When the approaching object is detected as moving in the buffering zone, the confirmation operation of the confirmation condition is activated. When the moving path falls in the warning area and fulfills the confirmation condition, the processing unit sends out a warning signal. Therefore, a potentially dangerous approaching object is accurately identified, and the warning is correctly sent.
