Vehicle Gate System Continuous Location Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing controllable gates require a significant delay after requesting to open, allowing unauthorized vehicles to enter during this time.
Innovation Solution
A vehicle gate system that includes a transceiver in the vehicle continuously transmitting location and code information, and a gate device with a transceiver and controller that continuously receives and approves requests based on the code and location, opening the gate only when the vehicle is sufficiently near.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gate is opened after a delay following the open request, then the system can process the request, but unauthorized vehicles can enter during this delay period
Solution Approach 1:
The system performs preliminary actions by continuously monitoring vehicle location and transmitting location information to the gate controller before the actual gate opening. The controller pre-processes authentication codes and continuously updates the gate state based on predicted arrival, so when the vehicle actually arrives, the gate can open immediately without delay, eliminating the security vulnerability period.
Solution Approach 2:
The system implements continuous feedback by having the vehicle transceiver continuously transmit location information to the gate controller. The controller receives real-time feedback about the vehicle's approach, continuously updates the gate state based on the received location data, and adjusts the opening timing dynamically. This closed-loop feedback mechanism eliminates the fixed delay problem while maintaining security through continuous authentication verification.
2Loss of time
If the gate opens immediately upon request, then the delay is eliminated, but the system cannot verify the vehicle's location or authentication properly
Solution Approach 1:
The system maintains continuous useful action by having the vehicle transceiver continuously transmit location information and authentication codes to the gate controller throughout the approach phase. The controller continuously processes this information, verifying both location proximity and authentication validity in real-time. This continuous verification process ensures that when the gate opens, both location precision and authentication are confirmed, eliminating the need for post-opening verification.
3Measurement precision
If the system waits for the vehicle to arrive before opening the gate, then location accuracy can be confirmed, but the gate remains closed during the approach period
Solution Approach 1:
The system applies dynamics by transitioning from a static gate state to a dynamic state where the gate controller continuously updates the gate opening state based on real-time vehicle location data. As the vehicle approaches, the controller dynamically progresses the gate from closed to opening state, preparing the mechanism in advance. This dynamic state management allows the gate to be opened at the optimal moment upon arrival, improving access efficiency while maintaining location accuracy through continuous monitoring.
