Summary of Automated Railway Gate Controlled by PIC16F877A
Summary: This project automates a railway level crossing using a PIC16F877A microcontroller, two rail-placed pressure sensors, an LCD status display, traffic lights, and a motor-driven gate. When a train triggers the first sensor, the motor lowers the gate and swaps road/rail signals; after the train passes and triggers the second sensor, the motor raises the gate and restores road traffic. The design was simulated in Proteus and programmed in MikroC Pro.
Parts used in the Automated Railway Gate Controlled by PIC16F877A:
- PIC16F877A microcontroller
- LCD display
- Pressure sensor (rail) - two units
- Traffic light (rail and road signals)
- Motor (for gate movement)
- Gate mechanism attached to motor
- Proteus simulation software (for testing)
- MikroC Pro compiler (for embedded C code)
Here I give you my project on Automated Railway Gate Controlled by PIC16F877A . It is very good project and if it is implemented by railway then they can save lots of money to paying salary for this purpose. For that project I use PIC16F877A, LCD display, two pressure Sensor (situated in rail line) ,Traffic light and motor (For closing and opening the railway gate).
Project Detail: Here I use two pressure sensor places in rail line 1 km way from both side of rail gate. When Rail is coming and touch the first pressure sensor the motor is start rotating and the gate is attach with motor and it slowly down and close the door. Before close the door rail traffic light was red and for road traffic it was green. After closed the gate rail signal is green and road traffic is red. Now train cross the gate after crossing gate it will touch other pressure sensor which is situated 1 Km way from other side of crossing. Now motor start anticlockwise rotating and gate slowly opening and after complete opening of the gate road traffic light will green and railway signal will red. I used LCD to display the total status of railway gate control.
I use Proteus to simulate my project and Micro c pro for writing the embedded C . In bellow found the embedded code which I used.

- What microcontroller is used in the project?
The project uses a PIC16F877A microcontroller. - How many pressure sensors are used and where are they placed?
Two pressure sensors are used, placed in the rail line 1 km from both sides of the gate. - What happens when the first pressure sensor is triggered?
When the first sensor is touched by the incoming train, the motor starts rotating to lower the gate and traffic signals are changed accordingly. - How does the system restore road traffic after the train passes?
After the train triggers the second sensor located 1 km beyond the crossing, the motor rotates anticlockwise to open the gate and road traffic light turns green. - What display is used to show gate status?
An LCD display is used to show the total status of the railway gate control. - Which software tools were used for simulation and coding?
The project was simulated in Proteus and coded using MikroC Pro. - What components control the traffic lights during gate operation?
The system controls traffic lights, setting rail traffic light green and road traffic light red when the gate is closed, and reversing when opened. - How is the gate physically moved?
The gate is attached to a motor which rotates to lower and raise the gate slowly.
