AUTOMATIC MOBILE PLATFORM AND GATE CONTROL AT RAILWAY LINES
The aim of the paper is to avoid the railway accidents happening at unattended railway gates by using ATMEGA_328 microcontroller, if implemented in spirit. Radio frequency (RF) transmitters and receivers are used to detect the train arrival and train accidents. Normally the mobile platform connects the two platforms through which the passenger can walk on the platform to reach on the next platform Sensors are placed on the two sides of track. if the train reaches one sensor the mobile platform
... he mobile platform will automatically close and allows the train to go through the tracks and then when the train leaves the second sensor the mobile platform will automatically open the bridging platforms. The microcontroller will sense the presence of train by using infrared sensor. So on sensing the train on one path controller will give pulses to the stepper motor to close the mobile platform automatically. The collision of two trains due to the same track also can be happened. This model is implemented using sensor technique. We placed sensors at a certain distance from the gate detects the approaching train and accordingly controls the operation of the gate. Also an indicator light has been provided to alert the motorists about the approaching train.
