Automatic Railway Level Crossing

AUTOMATED UNMANNED rail way line LEVEL CROSSING Abstract In the rapidly flourishing land like ours, accidents in the unmanned level crossings are increasing day by day. No fruitful steps have been taken so far in these areas. The objective of our project is to provide an automatic rail line opening at a level-crossing replacing the openings operated by the gatekeeper. It deals with deuce things. Firstly, it deals with the reduction of time for which the gate is being kept closed. And secondly, it provides safety to the road recitationrs by reducing the accidents.By employing the automatic railway gate control at the level crossing the arrival of the tag is find by the sensors rigid near to the gate and transmits the information to the gate controller via wired or wireless. Hence, the time for which it is closed is less compared to the manual of armsly operated gate. The operation is automatic i. e. , defect due to manual operation is prevented. By employing the automatic ra ilway gate control at the level crossing the arrival of spring up is detected by the sensor placed on either side of the gate at rough 3km from the level crossing.Hence, the time for which it is closed is less compared to the manually operated gates and also reduces the human labour. This type of gates can be employed in an unmanned level crossing where the chances of accidents are high and reliable operation is required. Since, the operation is automatic error due to manual operation will be prevented. Once the arrival of the train is feel, the sensed signal is sent to the microcontroller via, wired or wireless transmission and it checks for executable presence of fomite between the gates.Subsequently, buzzer indication and light signals on either side are provided to the road users indicating the closure of gates. Once, no vehicle is sensed in between the gate the motor is activated and the gates are closed. But, for the worst case if any hindrance is sensed it is indicated to the train driver by signals (RED) placed at about 1km, so as to bring it to halt well before the level crossing. When no obstacle is sensed GREEN light is indicated, and the train is to free to move. The departure of the train is detected by sensors placed at about 1km from the ate. The signal about the departure is sent to the microcontroller, which in turn operates the motor in opposition way and opens the gate. Thus, the time for which the gate is closed is less compared to the manually operated gates. as well as reliability is high as it is not subjected to manual errors. Components IR sensors or Vibration sensors, Microcontroller, L293D(driver IC), Stepper motor, Wireless Transmitter and Receiver, power supply. HARDWARE instruction execution Micro Controller Totally 40-pin DIP package manufactured withCMOS Technology. L293D (motor driver IC) Racially L293D 16DIP /ULN 2003 IC is used to drive the stepper motor. STEPPER force This is used to open and close the gates auto matically when it is rotated measure wise or anticlockwise direction. Stepper motor requires 500m amps current, so use the L293D drivers to drive the stepper motor. SOFTWARE IMPLEMENTATION Keil By 1. B. BHARATH KUMAR REDDY 113004045 2. P SAMBAshivah RAO 113004161 3. T.
