PROJECT DESCRIPTION

The main aim of this project is to process real-time data acquisition under supervisory control for large-scale remote industrial environment using a PC and embedded system.

Adapting a technology like SCADA (Supervisory Control and Data Acquisition) one can monitor and control all the processes of industries effectively, and thus, can save a lot of manpower.

For achieving this real-time scenario, a temperature logging system for remote plant operation is taken. Here some  temperature sensors are duly interfaced to an 8051 series microcontroller.

Data collected from the temperature sensors is continuously sent to the microcontroller, which is in turn connected to the PC. At front end, “DAQ System” (software) is loaded on computer which takes these values and displays them on its front panel, and also logs them in database.

One can set the parameters like set point, low limit and high limit on the computer screen. When the temperature of any sensor goes beyond the set point, then the microcontroller sends a command to the corresponding relay.

Heaters (shown as lamps) connected through the relay contacts (corresponding to their sensors) are turned off or on accordingly 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 unit mal functioning.

Hence, processes at hazardous areas can be controlled with more accuracy and better safety using SCADA. Adapting such technology will save both money and time.

NOTE: This project works only on Windows XP operating system. The computer should have a serial port (RS232) in it. Alternatively with a converter (not supplied) USB port can also be used.
