Plc Bible & Automatic Rail Gate Control & Security Using 'Plc' : Bangladesh Railway (BR)

This book is focused on the "Rail Way Gate" is controlled by human resource till now in our country. So some man-power is engaged for this non-productive work. Sometimes for some unfortunate signal transformation mistakes, citizen fall immeasurable damages. From the sense of humiliation development and save our resource by the gift of modern electronics. I take the research about "Automatic Rail-way gate control" by using 'Programmable Logic Controller (PLC). PLC is the devices which give us a vast option of process and procedure to make many works by using a single device. PLC can works in any situation or place whatever is it. It can works in low voltage of electronics environment. So any devices which can works with relay is used on PLC. There are many further scopes of development on this project. We worked on the railway gate control topology but the system is not end on this stage. It has many scopes on software development, method development and instrument enhancement etc. I want to develop it in future world.
