Wireless Red Signal Alerting For Trains
Railway networks are the biggest transportation networks used worldwide. Handling and managing such a vast network is not an easy task. The rail network consists of a lot of junctions and vast amount of signals on set distances to manage the train flow. Well the train driver needs to constantly check for any red signals on every post and decide whether to stop or move forward. It is very difficult to constantly keep track of every visual signal for the driver. So here we propose an automatic alerting system that alerts the driver of any red signal ahead. Our system works on the basis of Rf technology. Whenever a signal turns red, it sets on an rf transmitter fitted in it. The transmitter constantly transmits rf signals informing about a red signal. Now every train needs an receiver circuit on it. The receiver circuit when comes within certain range of the rf transmitter, it receives the input and sends it to the microcontroller. The microcontroller then processes this data in order to alert the driver about the signal ahead.
