Area of Science:

• Industrial Automation
• Control Systems Engineering
• Wireless Sensor Networks

Background:

• Harsh industrial environments with chemicals and moving parts pose risks to wired control systems.
• Data transfer in public access areas requires robust and secure communication methods.
• Traditional cabling in production plants can be costly and impractical.

Purpose of the Study:

• To design and implement a wireless water pumping control system for production plants.
• To offer a cabling-free solution for process plants with challenging environmental conditions.
• To reduce installation and maintenance costs while ensuring reliable operation.

Main Methods:

• Utilized a programmable logic controller (PLC) and industrial wireless local area network (IWLAN) technologies.
• Implemented a system with PLC, communication processor (CP), IWLAN modules, and distributed input/output (I/O).
• Employed Industrial Ethernet with Transport Control Protocol/Internet Protocol for communication, parameterization, configuration, and diagnostics.

Main Results:

• Successfully demonstrated a functional experimental setup for wireless water pump control.
• The system effectively controls water pumps based on tank levels using pressure transmitters and limit switches.
• The wireless solution proved suitable for industrial applications, offering flexibility and robustness.

Conclusions:

• The developed wireless control system provides a viable and cost-effective alternative to wired systems in harsh industrial environments.
• The system offers lower installation and maintenance costs, reliable operation, and a robust, flexible design.
• This solution is particularly beneficial for process plants where traditional cabling is not possible or practical.
