Electronic License Plate for Parking Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking systems cannot automatically determine whether a vehicle is authorized to use a specific parking place, making it difficult to enforce reservations or charging for designated parking areas such as those for the disabled, VIPs, or rental cars.
Innovation Solution
An electronic license device with a low-energy motion sensor and time-measuring means is used to transmit the vehicle's identification number and exact time of arrival to a central computer, linking the vehicle to the correct parking place by matching the arrival time with sensor data from parking sensor modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If parking sensor modules are used to detect vehicle presence, then occupancy status can be determined, but authorization verification cannot be performed
Solution Approach 1:
The patent combines the parking sensor module's vehicle detection function with an electronic license plate reader. The sensor module detects vehicle presence while the electronic license plate reader captures and transmits the vehicle's identification number to the central computer, enabling both occupancy detection and authorization verification through a unified system.
Solution Approach 2:
The central computer acts as an intermediary that receives data from both the parking sensor module and the electronic license plate reader. It matches the vehicle identification number with authorized vehicle data and correlates the detection time with parking place occupancy status, enabling comprehensive authorization verification without disrupting the existing sensor-based detection system.
2Extent of automation
If manual verification of authorized vehicles is performed, then parking regulations can be enforced, but automation and efficiency are reduced
Solution Approach 1:
The system implements automated feedback by continuously monitoring vehicle presence through sensor modules, capturing license plate numbers via electronic readers, and comparing them against authorized vehicle databases. The central computer automatically determines compliance and can trigger alerts or notifications when unauthorized vehicles occupy reserved parking places, ensuring reliable enforcement without manual intervention.
Solution Approach 2:
The system enables self-service verification where the electronic license plate reader automatically captures vehicle identification information and the central computer autonomously verifies authorization status against stored data. This eliminates the need for manual checking while maintaining high reliability through automated data matching and time-correlation algorithms.
3Productivity
If multiple parking places are monitored simultaneously, then overall parking management is improved, but individual vehicle tracking becomes difficult
Solution Approach 1:
The system performs preliminary actions by recording the exact time a vehicle is detected by the sensor module and capturing the license plate number at that moment. The central computer stores this temporal and identification data before the vehicle moves, enabling accurate matching of vehicles to specific parking places even when multiple transactions occur simultaneously across different locations.
Solution Approach 2:
The patent introduces a temporal dimension to the parking monitoring system by recording precise detection times for each vehicle. This time parameter serves as an additional identifier that allows the central computer to distinguish between multiple vehicles and accurately match each vehicle to its corresponding parking place, resolving ambiguities in high-utilization environments.
