The Control Panel (HMI) serves as the central command interface for the Automated Chemical Drum Cleaning and Decontamination System, providing real-time visualization of system status, process parameters, and operational data. It enables operators to initiate, pause, adjust, and terminate cleaning cycles, configure cleaning recipes, monitor safety interlocks, and access diagnostic information for maintenance and troubleshooting. The HMI receives input signals from operators via touchscreen or physical buttons, processes these commands through an integrated programmable logic controller (PLC) or industrial computer, and sends output signals to control system actuators (pumps, valves, heaters). Simultaneously, it collects and displays feedback data from sensors (temperature, pressure, flow, chemical concentration) throughout the system, updating the graphical interface in real-time to reflect current operational status. The panel is housed in a stainless steel enclosure (typically 304 grade) with a polycarbonate touchscreen, designed for industrial environments. It supports communication protocols such as Modbus TCP, Profinet, and EtherNet/IP, and operates within a temperature range of 0–50 °C. The screen size ranges from 10 to 15 inches with resolutions from 1280×800 to 1920×1080 pixels. The IP rating is between IP54 and IP65, ensuring dust and water resistance. Input voltage is 24 V DC (±10%), with power consumption between 15 and 30 W. Memory for recipe storage and logging ranges from 512 MB to 2 GB. The weight varies from 2 to 5 kg. The touchscreen type can be resistive or capacitive, suitable for glove operation. Operating pressure for the system is 1.0–1.6 MPa. All specifications are reference ranges; verify model-specific values and standards with the legal manufacturer or supplier.
The HMI operates by receiving operator inputs through the touchscreen or buttons. These commands are processed by an integrated PLC or industrial computer, which then sends control signals to actuators such as pumps, valves, and heaters. Simultaneously, the HMI collects feedback from sensors measuring temperature, pressure, flow, and chemical concentration. This data is displayed on the graphical interface in real-time, allowing operators to monitor system status and make adjustments. The HMI also manages safety interlocks and provides diagnostic information for maintenance.
