Vehicle Allocation Management via RFID Field Intensity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle allocation management systems require complex processing and are inflexible, unable to adapt to instantaneous situations, as they need to grasp work plans and manage vehicle status in advance.
Innovation Solution
A vehicle allocation management device that wirelessly communicates with RFID readers to determine vehicle presence and readiness for allocation based on radio field intensity information from electronic tags, allowing for real-time management without complex processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If work plan information and vehicle status information are managed in advance, then vehicle allocation can be controlled, but the system becomes inflexible and cannot adapt to instantaneous situations
Solution Approach 1:
The patent extracts the essential information needed for vehicle allocation (vehicle presence in stop area, continuous presence duration) from the complex work plan and vehicle status management system. By focusing only on these critical parameters detected through RFID readers, the system achieves flexibility without requiring management of comprehensive work plan information.
Solution Approach 2:
The system enables vehicles to self-report their status through RFID tags that automatically transmit information when vehicles enter or remain in stop areas. This eliminates the need for complex centralized tracking and manual status updates, allowing the system to adapt to instantaneous situations through automated, real-time data collection.
2Productivity
If real-time vehicle presence detection is implemented using RFID readers, then flexible allocation is achieved, but measurement precision requirements increase
Solution Approach 1:
The patent introduces RFID tags as intermediary elements attached to vehicles and RFID readers as intermediary detection devices. These intermediaries simplify the detection process by providing automatic identification and presence confirmation, reducing the precision requirements of direct detection systems while maintaining real-time monitoring capability.
Solution Approach 2:
The system performs preliminary detection of vehicle presence and continuous presence duration before making allocation decisions. By continuously monitoring and accumulating presence time data through RFID readers, the system prepares allocation-ready information in advance, enabling rapid response to instantaneous situations without requiring high-precision real-time measurement at the moment of decision.

AI summary
A vehicle allocation management device that can wirelessly communicate with a first reader device installed correspondingly to a stop area of a vehicle, including a receiver that receives, from the first reader device, radio field intensity information indicating the intensity of a radio field when the first reader device has received information from an electronic tag attached to the vehicle, a vehicle determiner that determines, based on the radio field intensity information, whether the vehicle is present in the stop area, and a vehicle allocation determiner that determines whether the vehicle is ready for allocation based on whether the vehicle is continuously present in the stop area for a predetermined time or more.
