Low Cost Scada System for Micro Industry

Abstract

Abstract: The main goal of the project is to use a SCADA system to wirelessly handle real-time data acquisition. It is necessary to monitor all processes and control the elements affecting them because several processes are run simultaneously in large industries. We can achieve the goal by utilizing a technology like Wireless SCADA (Supervisory Control and Data Acquisition). The AT89S52 microcontroller is interfaced with temperature sensors. The microcontroller wirelessly transmits data continuously from the sensors, which is subsequently received at a corresponding USB type trans-receiver attached to a PC or laptop. The computer software that logs the data into the database and displays it on the front panel of the PC or laptop is loaded. On the SCADA screen, we can change parameters like the set point, lower limit, and upper limit. The microprocessor sends an instruction to the appropriate relay as soon as a sensor's temperature drops below the predetermined level. In relation to their sensors, the field devices connected through relay contacts are switched from ON to OFF. For the purpose of triggering an alarm on the PC in the event of system failure, higher limit and lower limit options are available. SCADA can therefore be used to accurately and safely control processes at hazardous locations. On the SCADA screen, we can change parameters like the set point, lower limit, and upper limit
