automatic railway gate controll project

automatic railway gate controll project

We  read news papers very often about the railway accidents happening at un attanded railway gates. Present project is designed to avoid such accidents if emplemented in spirit.    this project utilises two powerful  ir transmitter and two receivers ,one pair of transmitter and receiver is fixed at up side (from the train comes) at a level higher than human beeing in exact alignment and similarly 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. I have considered 5 seconds for this project sensors are fixed at 1000 miters on both sides of the gate we call fore side sensor pair for commong towards gate train and aft sidesensors for the train just crosse the gate when foreside receiver get activated,  gate motor is turned on in one direction and gate is closed and stay closed till train crosses the gate and reaches aft side sensors  when aftside receiver get activated  motor turns in opposite direction and gate opens and motor stops . Buzzer will immidiately  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 gate. And stop sound after the train has crossed. Two other indications are provided for station master to know the status of gate   in case the gate is not closed due to any reason  a red signalling light fixed well before gate is enough to alarm the train driver to stop the train . The project is simple emplementation and subject to further improvement. Based on atmel 89c51 microcontroller.
