Transcript of Automatic Railway Gate Control and Track Switching

Automated Railway Crossing system using RFID
Nowadays, people always look for the safest means of transportation. Railways being the cheapest mode of transportation are preferred over all the other means. In the rapidly flourishing countries like the Philippines, many accidents at unmanned railway crossings occurred. This is due to the carelessness in manual operations of workers. For this reason, a lot of system with regards to the safety of many people is invented such as the Railway Gate System in view of protection. A railway gate system comprising a railway station having an elevated platform area for passengers to stand. In the principle of track switching, considering a situation where in an express train and a local train traveling in opposite directions on the same track; the express train allowed to travel at the same track while the local train has to switch on the other track. With the use of electronics, it enables the automation of the control of railway gates. As a train approaches the railway crossing the gate, it detects the train and accordingly controls the operation of the gate.
The development of Railway Gate System came up that led to the researchers proposal of the design of the “Automatic Railway Gate Control and Track Switching”.

TIMELINE
The study aims to create a working prototype of the “Automatic Railway Gate Control and Track Switching”. It intends to attain the following objectives:

1.To design a system that will enhance the existing railway gate control system.

2.To incorporate C-Programming in the design of the “Automatic Railway Gate Control and Track Switching”.

3.To show the application of automation in the miniature prototype of the “Automatic Railway Gate Control and Track Switching”.

ESTIMATED TIMELINE
Build an automated reliable system to reduce the amount of deaths caused by railway crossing accidents.
Define the main problems of the railway accidents (manned railway crossings).
Solving this problem using an automated system rather than man power.
Create and build this system using appropriate components.
Test this system and determine its level of reliability.

Asyiut train accident 2012
a car got stuck in the middle

the sensor know the last
carriage has passed?
a train fault was detected ?
WHAT IF
there was a faulted RFID ?
WHAT IF
WHAT IF
HOW DOES
Fast, continuous rotation motors
Used for anything that needs to spin at a high RPM
(revolutions per minute)
Used in computer cooling fans and radio controlled car wheels
Speed is controlled using pulse width modulation (PWM), a technique of rapidly pulsing the power on and off.
Assembly of 4 things: a DC motor, a gearing set, a control circuit and a position-sensor (usually a potentiometer)
Fast, high torque, accurate rotation within a
limited angle (180 degrees)
High performance BUT more complicated.
Slow, precise rotation, easy set up & control
Suited for 3D printers and similar devices where position is fundamental.
It rotates in discrete step angles
of the crossing ?
WHY CHOOSE ARDUINO ?
It is an open-source project, software/hardware is extremely accessible
It offers a variety of digital and analog inputs, SPI and serial interface and digital and PWM outputs
It is easy to use, connects to computer via USB and communicates using standard serial protocol
It is inexpensive, and comes with free authoring software
Uses of RFID technology
Public transport access ( eg. Oyster cards)
Animal identification
Car key fobs
Biometric passports
