I want circuit diagram and pcb layout of automatic railway gate control and track switching.

SUMMARY:

This project is developed using 8051 microcontroller, to avoid railway accidents
in automatic mode the railway gate, if implemented in the spirit. This project
uses two powerful IR transmitter and two receivers. one pair of transmitter and
The receiver is installed up-side (where the train runs) at higher levels than

fixed on 1 km on either side of the gate. We call the sensor along the trains
direction as "sensor" front edge, and the other as the "tail" the sensor side. At the leading edge
The receiver is activated, the shutter motor is included in one direction and the gate

Activation and the gate will close after 5 seconds, the time for drivers to clear the gate
area in order to avoid capture between the gate and stop sound after trains have
crossed.

Gate control:

Railways as a cheap form of transport is preferable to all other
When we go through means of daily newspapers, we are faced with many railroad
accidents occurring at unmanned railway crossings. This is mainly due to the
negligence in the manual or not working. We, in this project was the
the solution for the same. The use of simple electronic components, which we tried to
automate control of railway gate. As the train was approaching the railway crossing
on each side, sensors, placed at some distance from the gate detects
approaching train, and controls the operation of the gate. In addition
The indicator was provided to warn motorists of approaching trains.

Switching tracks

Using the same principle as the control gate, we developed the concept
automatic switching tracks. Given this situation, when the fast train and
suburban train travelling in opposite directions on the same path; express
allowed to move along the same track, and the train has to switch on
The other trail. Indicators have been provided Here to avoid a collision.
The switching operation is performed using a stepper motor. For practical purposes, this
can be achieved by using electromagnets.

8051 microcontroller

I/o ports 8051 expanded by connecting it to a chip 8255.8255
programmed as simple I/O port for connection to devices such as LEDs,
stepper motors and sensors. Learn more about 8255 are listed below.
The following block diagram shows the various devices connected to another
8255 ports. Each 8-bit ports and are called A, B, and C.
Individual ports 8255 can be programmed for input or output, and can also be
dynamically change the control register is programmed in simple mode, the I/O
port, port B and port C (upper) as output ports and port C (bottom) as a contribution
port.
