AUTOMATIC RAILWAY GATE CONTROL SYSTEM WITH SECURITY
ABSTRACT The main aim of the project is to establish automatic railway gates in place of existing manual railway gates, to reduce maintenance expenditure, human mistakes, and accidents. It is a low cost, maintenance free so that the concept is implemented by using an MCS 51 series micro controller. Here we established a railway gate moving towards top and bottom directions with the help of a 12V bi-directional linear DC motor, controlled by micro controller according to the firmware written in internal flash memory. Two sensors are attached to the railway gate to monitor whether the gate is properly closed or not, and to detect the person or vehicle movement while the gate is closing. Two more sensors are used to detect train movements i.e., entering and leaving. The intelligent firmware detects the train entry near by the railway gate with the help of entry sensor, and then the railway gate starts moving towards the downward direction. The motor stops rotating if any obstructions occurred during this operation. If the gate is closed in a specified time the controller allows the train to move on the track; otherwise the controller reduces the speed of train by putting appropriate control signals on the track until the gate is closed. Finally, the gate is not closed if the train is near by the gate the controller stops the train by putting appropriate control signals on the track until the gate is closed. The gate automatically moves towards upward direction after leaving the train. It can be detected by leaving sensor. With the help of this control system, we can avoid accidents that occur at railway gates, human mistakes, and high maintenance of the control operation. This project was implemented by using 8051 micro controllers. The programs were written in assembly language.
