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;
sbit lm0=P2^0;

ABSTRACT:
The objective of this paper is to provide an automatic railway gate at a levelcrossing replacing the gates operated by the gatekeeper. It deals with two things. Firstly, it deals with the reduction of time for which the gate is being kept closed. And secondly, to provide safety to the road users by reducing the accidents.
By the presently existing system once the train leaves t ....etc

Abstract:
Present project is designed using 8051 microcontroller to avoid railway accidents happening at unattended railway gates, if implemented in spirit. This project utilizes two powerful IR transmitters and two receivers; one pair of transmitter and receiver is fixed at up side (from where the train comes) 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 s ....etc
