Now a days, India is the country which having worlds largest railway network. Over hundreds of railways running on track everyday. As railway has straightway running as well as it has somewhat risky and dangerous as per as general public and traffic concern. As we know that it is surely impossible to stop the running train at instant is some critical situation or emergency arises. Therefore at the places of traffic density, suburban areas and crossings there is severe need to install a railway gate in view of protection purpose. Obviously at each and every gate there must be a attendant to operate and maintain it. In view of that, if we calculate the places of railway crossings and such places where it would to be install and overall expenditure, the graph arises and arises at the extent.
But, India, our country is a progressive country. It has already enough economical problems which are ever been unsolved. So, to avoid all these things some sort of automatic and independent system comes in picture. Now a days automatic system occupies each and every sector of applications as it is reliable, accurate and no need to pay high attention.
So, keeping all these things and aspects and need of such system our project batch tries to make such type of system with the help of various electrical, electronic and mechanical components. The thorough and detail information as per as construction and working is concerned, it is discussed furtherly.
An automatic control system is an arrangement of physical components connected in such a manner so as to direct or regular itself or some another system i.e. some controlled condition forming part of the system is maintained in a prescribed manner.
Automatic control system have influenced the current way of life. In recent year automatic control systems have been rapidly increasing importance in all fields of engineering. Its application covers a very wide range from design of precision control devices to design of massive equipments used for manufacture of steel and other industries.
ADVANTAGES OF ATOMATIC CONTROL SYSTEM:
The need of automation is due to or advantages of automatic
control system are :
1) It result in economy of operation.
2) Elimination of human error.
3) If frees human beings from mental tasks.
4) Saving in energy require
