The document outlines a project to develop an automatic railway gate control system utilizing an 8051 microcontroller, aimed at replacing manually operated gates to enhance safety and efficiency. The system uses infrared sensors to detect train movements and controls the gate’s operation, thereby reducing human error and maintenance costs. Key objectives include improving reliability, safety at level crossings, and minimizing the time for gate operations.

3. ABSTRACT
• The main aim of the project is to establish automatic railway gates in place of existing manually
operated 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 8051 Micro
controller. Here we established a railway gate moving towards top and bottom directions with the
help of a 2V bi-directional linear DC Motor, controlled by Micro controller according to the
program written in internal flash memory. Two sensors are used in this project to monitor
whether the gate is properly closed or not. 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. The gate
automatically moves towards upward direction after leaving the train. It can be detected by
leaving sensor. With 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 using 8051 Microcontroller .

4. Project Objective
• Provide an automatic railway gate at a Level crossing replacing the
gates operated by the gatekeeper for:
• Reduction of time for closing and opening the gate.
• Higher reliability as it is not subjected to manual errors.
• provide safety to the road users by reducing the accidents.
• level crossing:
• The place where track and highway road intersects each other at the
same level is known as "level crossing".

7. WORKING PRINCIPLE
• The arrival of train is detected by the sensor placed on either side of the gate at
about 5km from the level crossing
• Once the arrival is sensed,the sensed signal is sent to the microcontroller.
• Subsequently, buzzer indication and light signals on either side are
• provided to the road users indicating the closure of gates.The departure of the
train is detected by sensors placed at about 1km from the gate.
• The signal about the departure is sent to the microcontroller, which in
• turn operates the motor and opens the gate.
