SCADA (Supervisory Control And Data Acquisition) for Remote Industrial Plant:
PROJECT DESCRIPTION

The intention of the project is to design in achieving and controlling the real time data remotely by the administration for large scale industries. Many processes are going on in the large scale industries where monitoring and controlling all the processes  at a time is not possible manually . It is achieved by the adapting technology like SCADA (Supervisory Control and Data Acquisition).

For achieving this real-time scenario, a temperature logging system for a remote plant operation is taken. Here temperature sensors are interfaced to the 8051 microcontroller with help of a 8 channel ADC device where the temperature sensors collect the data and send them to the microcontroller.  The heaters (shown as lamps) are connected to relay contacts corresponding to their sensors which are controlled  by the relay driver IC.  This system is interfaced to the PC using RS-232 cable having a GUI for interactive actions by the operator.

Whenever temperature of a sensor increases from set point of the GUI, the microcontroller sends a command to the corresponding relay. The relay is made to switch ON and OFF the heater (a lamp load)  to maintain the set temperature.  High limit and low limit features are available for generating an AV alarm on the PC in the event of any abnormal situation.

At the front end, “DAQ System” software is loaded on the computer which takes sensor values and displays them on in front of the panel and also logs them in a database.  The software has the provision for setting of the sensor parameters such as set point, low limit and high limit on the computer screen.

Hence, in the large scale industrial plants control many processes with more accuracy and better safety using SCADA. Adapting such a technology will save both money and time.

Q & A
Q:  What is SCADA? Where is it used?
A:  SCADA (supervisory Control and Data Acquisition) is a type of industrial control system (ICS). Industrial Control Systems are computer-controlled systems that monitor and control industrial processes that exist in the physical world.
Q:  Can I replace lamp with any industrial load?
