INDUSTRIAL AUTOMATION THROUGH INTERNET PROJECT FOR POLYTECHNIC AND ENGINEERING STUDENTS

Industrial automation through internet

Industrial automation is a latest technology for industrial control. There are several methods to automate the industrial process. But for automation through internet is a medium which is used to make connection between the remote server and the controlled machines .

The medium can have two types:

1.        Wired medium

2.        Wireless medium

When we use the wired connection system then we need to connect wires from control panel to the controlled machines. This system can be used when the distance between the control panel and controlled devices are not too much. At the same time the cost of wires and the cost of maintaining the communication medium may be extent.

We can use wireless communication methods to avoid the use of physical wires.  We can establish a communication system which can operate up to some kilometers distance. This type of system is costly and also has limitation of distance as the communication system has to be designed for a certain distance.

All These problems can be overcome if we use the internet as our media of communication. The distance between the control station and the controlled machines is not a problem as the internet is available everywhere. We just need to have internet connections at both sites. The cost of maintaining the communication system is just the internet bill of two connections with installation cost of hardware. We can use that internet connection for all other application.

In This project we are developing a controller card that will be attached to the serial port of the computer at the factory site. Our aim to control this controller card from any computer in the world connected to the internet. The connections of this control card are given to the machines through relays.  An LCD display is also attached to this card to display the message received from the control station.

By using this project we can perform the following functions

1.Check the status of industry

 2.Switch on a device

 3.Switch off a device

 4.Change the state of operation for a device

 5.Send message & display on LCD

 6.Play alarm until someone not check the message (especially for  emergency conditions)
