Abstract: The main end of the design is to measure the speed of trains and to insinuate it to the station control room TCAS, if the train exceeds it’s maximum speed limit. Then we will place two IR transmitter receiver dyads with some distance, along the road. And by calculating the time difference between the activation of two IR receivers as per the law sense, the speed of the train can be calculated. So now we will design the design in such a way that the regulator will be connived to the two IR receivers and to the GSM modem through a line motorist IC MAX232 for periodical communication.

Then GSM modem is used to shoot the SMS to the control room to insinuate about the overspeeds.However, the GSM modem sends corresponding data to the station control room TCAS as per the law sense, If any train crosses the speed limit means the time between the activation of two IR detectors is lower than the time limit.

A. Literature Review

Thissystemhasbeen designedassumingthatthemaximumadmissiblespeed for railroadsismoreover 40kmph or 120kmphasper the rules. Before operation, using a multimeter we’ve to check whether the power force affair iscorrect. However, applypower force to the circuit by flipping switch to ‘ on’ if yes. In the circuit, we use long cables for connecting the two printDIODEs, sothatwecantakethemoutofthePCBandinstallononesideoftheroad, 100measurespiecemeal. We’veinstalledtwo IRDiodetransmitters (similarasIRDiode firebugs)on theother sideoftheroadexactlycontrarytotheprintDIODEs similarthatIR Diode light falls directly on the print DIODEs. Reset the circuit by pressing RESET switch, so the display shows ‘0000’. Stationary TCASunitshallalsotransmittheMovementAuthoritytotheLocoTCASin itsgovernancein stationarea.
