Parking Management System Using Segmented Detection and Universal Readers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking management systems face challenges in determining whether a vehicle is parked in a designated space and calculating parking fees accurately, often requiring complex structures and technologies.
Innovation Solution
A parking management system that uses reading devices to identify vehicles, vehicle detection devices to track presence, and a management device to determine parking status and calculate fees based on entry and exit times, with features like secondary reading devices and abnormality determination units to handle various scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If reading devices and vehicle detection devices are used to determine parking status, then parking management accuracy is improved, but device complexity increases
Solution Approach 1:
The system divides the parking management function into two independent components: reading devices for identification and vehicle detection devices for presence confirmation. This segmentation allows each component to perform its specific function with high accuracy while keeping the overall system structure modular and manageable, resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The reading devices serve multiple purposes: they identify vehicles entering the parking area, track vehicles moving between parking areas, and provide identification data for fee calculation. This multi-functionality reduces the need for separate specialized devices, thereby improving accuracy without proportionally increasing system complexity.
2Productivity
If parking fee calculation is based on entry and exit times, then productivity is improved, but loss of time in time measurement increases
Solution Approach 1:
The reading devices record the entry time of vehicles immediately when they enter the parking area, storing this data in advance. When vehicles exit, the system retrieves the pre-recorded entry time and automatically calculates the parking duration and fee. This preliminary recording action enables rapid fee calculation without time loss during the exit process, improving productivity while maintaining accurate time measurement.
3Adaptability or versatility
If multiple reading devices are deployed to cover multiple parking areas, then adaptability is improved, but device complexity increases
Solution Approach 1:
Each reading device is designed to be universal, capable of identifying vehicles and determining whether they are entering or exiting any parking area within the management zones. The reading device at one boundary can identify vehicles that will subsequently be detected by vehicle detection devices in other parking areas, eliminating the need for dedicated reading devices at every single parking area and reducing overall system complexity while maintaining full adaptability.
Data Source
AI summary
A parking management system includes a reading device, a vehicle detection device, and a parking management device. The reading device reads identification information for identifying a vehicle from an identifying body mounted on the vehicle that enters a boundary of a management area including parking spaces in each of which one vehicle can be parked. The vehicle detection device detects the vehicle that exists in each of the parking spaces. When the identical identification information is not read again during a passing determination time from a time point at which the identification information is initially read by the reading device, and when a new vehicle is detected in the parking space by the vehicle detection device during the passing determination time, the parking management device determines that the vehicle indicated by the identification information is parked in the parking space.
