how does metro train function ?
Answers
Metro train functions on the use of electricity.
The metro rails actually work on the principle of DC shunt motors ...no usage of gears ...many parts are electrified .
The METRO consists of microcontroller with the RF receiver and the voice recorder chip with speaker .The whole system is attached to the vehicle (Train). When the project is powered the train moves, until it encounters a RF card placed beneath the track. The encoded RF transmitters are placed in the railway stations.
The voice chip will play the voice and this will be heard in the speaker. This voice is repeated till the train leaves the station. In this module LCD is used for the
display purpose, in the programming what we have stored it will be displayed in the LCD. For E.g.: station number will be displayed when the train reaches the station, even when the train is leaving it will display on the LCD even it will announce it using the IC chip, the train is in which station and when it is leaving also
