Abstract

The key objective of the project is to process the real time data acquisition wirelessly using SCADA system. In large industries several processes are carried on concurrently, so there is a necessity to observe all the processes and govern the factors affecting the process. By using a technology like Wireless SCADA (Supervisory Control and Data Acquisition) we can meet the goal successfully. To manifest this real-time situation, a temperature recording system for a remote plant set-up is developed by Visual Studio. Temperature sensors are interfaced to the AT89S52 microcontroller. Information collected from the sensors is continuously sent over 2.4GHz trans-receiver wirelessly to the microcontroller which is then received at the corresponding 2.4 GHz USB type trans-receiver connected to a PC / Laptop. In the computer “DAQ System” (software) is loaded which takes the collected data and presents them on PC / Laptop’s front panel, and also logs them into the database. We can customize parameters like set point, lower limit and higher limit on the SCADA screen. As the temperature of a sensor goes below set point the microcontroller issues command to the respective relay. The field devices interfaced through relay contacts (with respect to their sensors) are turned OFF (or ON in vice versa). Higher limit and lower limit features are present for producing an alarm on the PC in the event of breakdown of system. Therefore, processes at dangerous places can be controlled with good accuracy and enhanced safety using SCADA.
