ABSTRACT

Aim of this project is to operate and control the unmanned railway gate in the proper manner in order to avoid the accidents in the unmanned railway crossing. The train accidents due to the absence of human power in the railway crossing are the major problems faced by the population. In order to overcome the accidents due to the above problem

The components to be involved in this project are PIC microcontroller, IR transmitter and receiver and the control circuit for the railway-crossing gate. The IR transmitter and a rec ....etc

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

Hello, i'm israr from 8th semester eee. i chose automated railway gate control using plc (ge versamax) as my project. i used ir sensors to detect train and send signal to open the gate. so far in the input side there is no problem at all. but the output , that is a l293d driver controlling dc geared motors i don't know how to connect the l293d to the plc output. in l293d there 4 input terminals. 2 for each and you are suppoesed to give '0' that is a ground signal to i1 or i2 to operate in anti and clockwise respectively. but how do i give this ....etc
