Automatic Railway Gate Security
Automatic Railway Gate Security is a 8051 microcontroller based project which can be made as major final year project by students. This Project avoid railway accidents happening at unattended railway gates and thus maximizing the security. This project utilizes two powerful IR transmitters and two receivers; one pair of transmitter and receiver is fixed at up side at a level higher than a human being in exact alignment and similarly the other pair is fixed at down side of the train direction. Sensor activation time is so adjusted by calculating the time taken at a certain speed to cross at least one compartment of standard minimum size of the Indian railway.

The I/O ports of the 8051 are expanded by connecting it to an 8255 chip. The 8255 is programmed as a simple I/O port for connection with devices such as LEDs, stepper motors and sensors. More details of the 8255 are given later. The above block diagram shows the various devices connected to the different ports of an 8255. The ports are each 8-bit and are named A, B and C. The individual ports of the 8255 can be programmed to be input or output, and can be changed dynamically. The control register is programmed in simple I/O mode with port A, port B and port C (upper) as output ports and port C (lower) as an input port.
