Paddle shaft locking mechanism for gate transmission protection

A transmission method with a protection device to enable access and damage control at a fare gate, the transmission method comprising:

• rotating a paddle shaft to drive a gate paddle via a motor;
• allowing transmission through the fare gate by operating the gate paddle;
• and
• locking the paddle shaft using the protection device in case of fare evasion at the fare gate, by:
• integrating a locking mechanism at the paddle shaft, wherein the locking mechanism is operable to:
• pulling a plurality of shaft arms of the paddle shaft via a solenoid when torque applied to the paddle shaft reaches a preset threshold;
• locking the paddle shaft to stop rotation of the gate paddle;
• and
• blocking transmission through the fare gate.
