AUTOMATIC
CONTROL FOR UNMANNED RAILWAY GATE
The
cheapest way to remotely control a device within a visible range is via
Infra-Red light. Almost all audio and video equipment can be controlled this
way nowadays. Due to this wide spread use the required components are quite
cheap, thus making it ideal for us to use IR control for our own projects.
Infra-Red actually is normal light with a particular color. We humans can't see
this color because its wave length of 950nm is below the visible spectrum.
That's one of the reasons why IR is chosen for remote control purposes, we want
to use it but we're not interested in seeing it. Another reason is because IR
LED’s are quite easy to make, and therefore can be very cheap.
Automatic Control For UnManned Railway Gate projects main
idea is to develop a application where railway gates will be controlled
automatically using microcontroller system. Implementing this system can save
lot of efficiency in controlling railway gates. This application uses 89s52
microcontroller and IR transmitters and receivers.
In present system railway gates are maintained manually,
but there are many cases where human errors which had caused huge damages. In
order to develop this application accuracy is most important so there is need
to be a quality check before implementing in reality.
In this project two powerful transmitters and receivers are
used, among them one transmitter and one receiver is used at the upside at the
human level and other pair is fixed at downside.
Present project is designed using 89S52 microcontroller
to avoid railway accidents happening at unattended railway gates, if
implemented in spirit. This project utilizes two powerful IR transmitters and
two receivers; one pair of transmitter and receiver is fixed at up side (from
where the train comes) at a level higher than a human being in exact alignment
and similarly the other pair is fixed at down side of the train direction.
Sensor activation time is so adjusted by calculating the time taken at a
certain speed to cross at least one compartment of standard minimum size of the
Indian railway. We have considered 5 seconds for this project. Sensors are
fixed at 1km on both sides of the gate. We call the sensor along the train
direction as ‘foreside sensor’ and the other as ‘aft side sensor’. When
foreside receiver gets activated, the gate motor is turned on in one direction
and the gate is closed and stays closed until the train crosses the gate and
reaches aft side sensors. When aft side receiver gets activated motor turns in
opposite direction and gate opens and motor stops. Buzzer will immediately
sound at the fore side receiver activation and gate will close after 5 seconds,
so giving time to drivers to clear gate area in order to avoid trapping between
the gates and stop sound after the train has crossed.
The same principle is applied for track switching. Considering a situation
wherein an express train and a local train are traveling in opposite directions
on the same track; the express train is allowed to travel on the same track and
the local train has to switch on to the other track. Two sensors are placed at
the either sides of the junction where the track switches. If there’s a train
approaching from the other side, then another sensor placed along that direction
gets activated and will send an interrupt to the controller. The interrupt
service routine switches the track. Indicator lights have been provided
to avoid collisions. Here the switching operation is performed using a DC
motor. Assuming that within a certain delay, the train has passed the track is
switched back to its original position, allowing the first train to pass
without any interruption. This concept of track switching can be applied at 1km
distance from the stations.
