Automation in unmanned railway level crossing

This paper deals mainly with the automation in unmanned and manned railway crossings. In recent days the accidents in railway level crossing are increasing. There are two types of level crossing Manned and Unmanned. The accidents occurring in both level crossings are very severe. Our work uses simple mechanical and electrical components to control the railway gate. The Infrared detector which is placed at a few distances away from the gate detects the train and sends the signal to the controller. From the controller the signal is send to the timer which is connected to LED display near the gate. Timer displays the time remaining for closing or opening of the gate according to the necessary situation. The power is transmitted from the controller to the motor which is connected to the L-shaped cylinder through the pinion of rack and pinion arrangement. This rotary motion of the pinion produces the linear motion of the rack. This linear motion of the rack actuates the horizontal and vertical piston one by one of the L cylinder which in turn opens or closes the gate. Thus our paper presents a highly secured and safe automated level crossing at low cost, which requires no human monitoring.
