We all know that currently India is the country which is having the world’s largest railway network. There are a number of railways which are running on the track on regular basis. Railway is a straightway running along with it also contains somewhat which is risky as well as dangerous for the general public and traffic concern. This problem should be solved but we all know very well that it is definitely impossible to stop the running train at instant when some kind of critical or emergency situation arises.
So there is the extreme necessity to install a railway gate in view of protection purpose at the places of traffic density, suburban areas as well as crossings. In addition to this, there will be an attendant at each and every gate in order to operate as well as maintain it. For the purpose of doing that, if there is a calculation of the places of railway crossings and all such places where it needs to be installed, then the graph will arise and arise at the extent.
But our country is the progressive country which is already containing the economical problems with unsolved solutions. In order to avoid all these issues, the concept of automatic and independent system has been brought by the researchers. These kinds of systems occupy each and every sector of the applications due to its reliability, accuracy and less attention to be paid.
The automatic control system by the researchers is an arrangement of physical components which are connected in such a manner so that it could direct or regular itself or some another systems or controlled conditions forming part of the system which is maintained in the prescribed manner. It has influenced the present way of life. Recently, its application is increasing in all the sectors as it covers a wide range.
Advantages of automatic control systems:
The necessity of automation is increasing due to its various advantages which are as follows:
- It brings economy of operation.
- It eliminates the possibility of human error.
- Humans are no more need to do mental tasks.
- It saves the requirements of energy.
- It boosts the efficiency.
