we tried this source code for automatic railway gate.. it doesnot show any error while compiling in keil.
but we are not getting the output in proteus.. it is correct until the gate opens.. bt nothing else happens after that. pls help

sbit ir1=P1^6;
sbit ir2=P1^7;

future scope of automatic railway gate control system

Early level crossings had a flagman in a nearby booth who would, on the approach of a train, wave a red flag or lantern to stop all traffic and clear the tracks. Manual or electrical closable gates that barricaded the roadway were later introduced. The gates were intended to be a complete barrier against intrusion of any road traffic onto the railway. In the early days of the railways much road traffic was horsedrawn or included livestock. It was thus necessary to provide a real barrier. Th ....etc

Automatic Railway Gate Controller(Using 8051)

In general, Railway gates are opened or closed manually by a gate keeper. The information about arrival of train for opening or closing of door is received from nearby station. But some railway crossings are totally unmanned and many railway accidents occur at these unmanned level crossings.

To avoid the human intervention at level crossings completely, we need to automate the process of railway gate control.

This project deals with an interesting manner of automating the railway gate contr ....etc

Abstract

When it comes to public safety and personal safety, it is always desirable to improve upon the way people are warned about potentially dangerous situations and also we require 100 percent perfection in warning method. To date there does not appear to be any railroad collision avoidance system that can effectively warn a person when train is on its track. The conventional railway accident avoiding system uses warning lights and human controlled gates to alert a motorist that there is an oncoming train. The most of the railroad crossing ....etc

The first single-chip microprocessor was the 4-bit Intel 4004 released in 1971. With the Intel 8008 and more capable microprocessors available over the next several years. These however all required external chip(s) to implement a working system, raising total system cost, and making it impossible to economically computerize appliances.

The first computer system on a chip optimized for control applications was the Intel 8048, released in 1975, with both RAM and ROM on the same chip. This chip would find its way into over one billion PC keyboa ....etc
