1Extent of automation
If a high degree of automation is implemented in lyophilization controllers, then process control capability is improved, but insight into machine parameters and process state is lost
Solution Approach 1:
The system implements feedback by continuously monitoring process parameters (temperature, pressure, power, cooling) and displaying them in real-time on the user interface. This allows operators to see the current state of the lyophilization process and make informed decisions, resolving the information loss caused by automation while maintaining automated control.
Solution Approach 2:
The graphical user interface acts as an intermediary between the automated control system and the operator. It translates complex machine parameters into visual representations (phase diagrams with plotted points, process curves) that provide insight into the process state without requiring the operator to directly interact with the automated control system's internal logic.
2Device complexity
If basic automation control is used, then device complexity is reduced, but diagnostic capability and process optimization are hindered
Solution Approach 1:
The system plots process parameters on a phase diagram, adding a visual dimension to the data. Instead of merely displaying numerical values, the system represents temperature and pressure as coordinates on a phase diagram, allowing operators to visually assess whether the process is in the desired sublimation region, thereby enhancing diagnostic capability without complicating the controller structure.
Solution Approach 2:
The system uses color-coded indicators and visual cues on the graphical interface to represent different process states and parameter ranges. This visual encoding allows operators to quickly diagnose process conditions and identify issues without complex instrumentation, maintaining simple device structure while improving detectability.
