Crossing Gate Control via Vehicle Light Signal Morse Code
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crossing gate systems require the installation of multiple RF cards on vehicles, increasing costs and compromising aesthetics, as well as being inconvenient for frequent entry and exit at multiple locations.
Innovation Solution
An apparatus that automatically controls a crossing gate by sensing light signal patterns, using a password setting unit, signal sensing unit, and controller to convert light signals into Morse code for opening or closing the gate, eliminating the need for RF cards by using light signals from the vehicle's headlights or brakes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RF cards are installed at the vehicle for crossing gate control, then the crossing gate can be opened automatically, but the cost increases and the aesthetic appeal of the vehicle is lowered
Solution Approach 1:
The patent extracts the identification function from the RF card system and relocates it to the vehicle's existing light signal system. Instead of adding external RF cards to the vehicle, the system uses the vehicle's headlights and brake lights to encode identification information, thereby eliminating the need for additional hardware on the vehicle while maintaining automatic gate operation capability
Solution Approach 2:
The patent makes the vehicle's light signal system serve multiple functions: its original illumination/safety function plus a new identification/authentication function for crossing gate control. By encoding Morse code sequences in the light signals, the same lights that illuminate the road also transmit identification data to the gate system, eliminating the need for dedicated RF cards
2Adaptability or versatility
If multiple RF cards are installed at the vehicle for different locations, then the vehicle can enter and exit multiple places, but the aesthetic appeal is lowered and installation becomes inconvenient
Solution Approach 1:
The patent creates a universal light-based identification system that can be used at multiple crossing gate locations without requiring different physical cards. The vehicle's light signal system serves as a universal key that can be recognized by any gate equipped with the corresponding detection system, enabling access to multiple locations with a single implementation
Solution Approach 2:
The patent replaces the mechanical/electronic RF card system with an optical signal system. Instead of physically installing and managing multiple electronic cards, the system uses light signals to transmit identification information, simplifying the system to something that requires no physical installation on the vehicle beyond utilizing existing lights

AI summary
An apparatus for automatically controlling a crossing gate being installed at an entrance/exit way of a vehicle and controlling entrance/exit of the vehicle, including: a password setting unit for setting a combined row of input numbers or characters as a password; a signal sensing unit for sensing a change in an amount of light of light signal patterns of the vehicle; and a controller including a first signal converter that analyzes the sensed change in the amount of light of light signal patterns of the vehicle and that converts the analyzed light signal patterns into a Morse code, a second signal converter that converts the converted Morse code into a combined row of numbers or characters, and a driving controller that controls opening/closing of the crossing gate depending on whether the converted combined row of numbers or characters is the same as the password set by the password setting unit.
