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 Ëœforeside sensorâ„¢ and the other as Ëœaft side sensorâ„¢. 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..................[:=> Show Contents <=:]

not its frequency, so an F.M signal remains virtually unchanged. F.M is also better able to transmit sounds in stereo than A.M. Commercial F.M broadcasting stations transmit their signals in the frequency range of 88 megahertz (MHz) The project is designed using F.M COMMUNICATION 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 ..................[:=> Show Contents <=:]

This type of regulation is ideal for having a simple variable bench power supply. Actually this is quite important because one of the first projects a hobbyist should undertake is the construction of a variable regulated power supply. While a dedicated supply is quite handy e.g 5V or 12V,itâ„¢s much handier to have a variable supply on hand, especially for testing.

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..................[:=> Show Contents <=:]
