Traffic Gates Operation TRIZ Cases
- Rail Crossing Gate BLDC Hold Control After Brake Failure
When a crossing gate brake fails to hold position, BLDC motor control keeps the arm stable, reducing abrupt movement and wear.
- Railroad Crossing Gate BLDC Holding After Loss-of-Brake
A BLDC motor takes over gate-arm holding when the brake fails, keeping railroad crossings operational while reducing wear and maintenance.
- Level Crossing Controller with Dual-Channel Track Circuit and Wheel Sensor Detection
A level crossing controller uses track circuits as transmission media for wheel sensor signals to reduce cabling.
- Railroad Crossing Gate Horizontal Brake Mechanism
A horizontal brake feature locks railroad crossing gates in the lowered position using power-on friction.
