Abstract
With the rapid development of industrial automation technology, the intelligence and reliability of water level monitoring and control systems have become research hotspots. This study aims to design a water-level monitoring and control system based on programmable logic controllers (PLC) to meet the modern industry's demands for efficiency and stability in water level management. By analyzing issues in traditional water level control systems, such as slow response, low accuracy, and poor anti-interference capability, this paper proposes an integrated solution combining sensor technology, PLC control technology, and human-machine interaction interfaces. The system adopts a modular design approach, utilizing liquid level sensors to collect real-time water level data, performing logical operations and control outputs via PLC, and enabling parameter settings and status display through a touch screen. Experimental results indicate that the system can accurately monitor water level changes and automatically adjust control strategies, demonstrating excellent stability and adaptability under various complex operating conditions. Furthermore, this study innovatively incorporates a fault diagnosis mechanism capable of issuing timely alarms and switching to a safe mode during abnormal situations, significantly enhancing the system's reliability and safety.
