AI Technical Summary

Technical Problem

Fare gates in transit systems face mechanical degradation due to constant use, leading to malfunctions, longer queues, operational costs, security vulnerabilities, and fare evasion, especially when commuters pass with strollers, luggage, or children, causing torque overload and potential damage to internal components.

Method used

A paddle shaft locking mechanism integrated with a solenoid-driven locking mechanism that stops the paddle shaft rotation and blocks transmission through the fare gate when torque exceeds a preset threshold, preventing fare evasion and protecting internal components.

Benefits of technology

Prevents fare evasion and reduces mechanical damage to fare gates by stopping unauthorized access and limiting torque overload, ensuring operational integrity and reducing maintenance costs.

Abstract

A transmission system with a protection device to enable access and damage control at a fare gate. The transmission system includes a motor, a gate paddle, and the protection device. The motor rotates a paddle shaft to drive the gate paddle. The gate paddle is operable to allow transmission through the fare gate. The protection device locks the paddle shaft in case of fare evasion at the fare gate. The protection device includes a locking mechanism integrated at the paddle shaft. The locking mechanism pulls shaft arms of the paddle shaft via a solenoid when torque applied to the paddle shaft reaches a preset threshold. The locking mechanism further locks the paddle shaft to stop rotation of the gate paddle and blocks transmission through the fare gate.
