Flow Channel Interlock Control for Fluid Mixing Prevention

The patent uses templates to store predefined control program patterns for common flow channel operations. Instead of manually creating control programs from scratch, the system copies and adapts these pre-defined templates, significantly reducing time consumption while maintaining the ability to customize control logic for different flow channel structures and processes.

The patent implements automatic generation of control programs using a computer that automatically creates control logic based on process information and template patterns. The system also performs self-validation to detect potential errors and inconsistencies in the generated programs, reducing human error while maintaining control accuracy and simplifying the overall process.

The patent incorporates interlock control conditions directly into the control program generation process itself, rather than adding them as separate post-processing steps. The system automatically identifies potential fluid mixing scenarios and embeds preventive interlock logic during program creation, ensuring safety requirements are met while avoiding the need for complex additional control layers.

The patent introduces a user interface that serves as an intermediary between the operator and the automatic program generation system. This interface allows operators to easily specify process information and constraint conditions through simplified input methods, while the system automatically handles the complex program generation and validation processes, maintaining both high productivity and ease of operation.
