Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current traffic monitoring systems cannot effectively detect violations by objects without visible number plates, such as shared bicycles, leading to disrupted traffic order and increased accidents.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional cameras are used to monitor traffic violations, then vehicles with visible number plates can be detected, but objects without number plates (such as shared bicycles) cannot be detected
Solution Approach 1:
The system uses a mobile terminal that can function both as a traffic signal state acquisition device and as a detection device for objects without number plates. The terminal integrates multiple functions including receiving traffic signal states from servers, acquiring beacon information for positioning, and determining violation status, making it adaptable to different detection scenarios beyond just camera-based number plate recognition
Solution Approach 2:
The patent introduces beacon information as an intermediary element to enable detection. Instead of directly detecting objects without number plates using cameras, the system uses beacon signals from surrounding intersections as a mediator to determine the terminal's position and infer traffic signal violations, thus solving the detection coverage problem
2Adaptability or versatility
If manual investigation is used to detect shared bicycle violations, then detection can be performed, but traffic order disruption and accidents increase due to delayed response
Solution Approach 1:
The system performs preliminary action by having the mobile terminal proactively acquire traffic signal states from the server in advance and continuously monitor its own position through beacon information. This allows the terminal to determine potential violations before they result in accidents, enabling preventive rather than reactive detection
Solution Approach 2:
The system establishes a feedback loop where the terminal receives traffic signal states from the server, compares them with its own position and movement status, and automatically determines whether a violation has occurred. This automated feedback mechanism replaces manual investigation and provides immediate detection, improving traffic safety
3Measurement precision
If camera-based number plate recognition is used, then vehicle identification is accurate, but objects like shared bicycles without visible number plates cannot be identified
Solution Approach 1:
The patent replaces the mechanical camera-based optical recognition system with an electronic information processing system. Instead of using cameras to capture and recognize number plates, the system uses the mobile terminal to electronically acquire traffic signal states from the server and process beacon information for positioning, thereby identifying objects without physical number plates

AI summary
The present disclosure provides a method and a device for detecting whether an object violates a traffic signal. The terminal moving along with the object is in communication with the network to acquire the state of the traffic signal in the moving direction of the object; when the acquired state of the traffic signal is in the no-passing state, the terminal determines a current position of the object according to beacons surrounding the intersection where the object is; and then, the terminal moving along with the object detects whether the object violates the traffic signal according to the determined current position of the object.
