METHOD FOR DIAGNOSING AN OPEN- AND/OR CLOSED-LOOP CONTROL SYSTEM, AND OPEN- AND/OR CLOSED-LOOP CONTROL SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240028023 titled 'METHOD FOR DIAGNOSING AN OPEN- AND/OR CLOSED-LOOP CONTROL SYSTEM, AND OPEN- AND/OR CLOSED-LOOP CONTROL SYSTEM
Simplified Explanation
The patent application describes a method for diagnosing the control system of a process engineering plant. The plant has multiple actuating units that control the process fluid, and a central unit that receives data from these units.
- The method involves detecting specific control data from the actuating units, such as setpoint values, actual values, setpoint-actual difference values, or control values.
- A local diagnosis code is generated by one of the actuating units based on the detected control data.
- The diagnosis code is then transmitted from the actuating unit to the central unit.
- The local diagnosis code is transformed into a global diagnosis code.
- A logical condition is defined for a diagnosis deduction logic, which determines a predetermined deduction result when applied to at least one diagnosis code.
- A deduction result is determined based on the diagnosis code(s).
Potential applications of this technology:
- This method can be used in various process engineering plants, such as chemical plants, power plants, or manufacturing plants, to diagnose and monitor the control system.
- It can help identify and address issues or malfunctions in the actuating units, allowing for timely maintenance or repairs.
- The method can improve the overall efficiency and reliability of the control system, leading to better process control and optimization.
Problems solved by this technology:
- The method provides a systematic approach to diagnose the control system, allowing for early detection of issues and preventing potential failures.
- It enables local diagnosis by the actuating units, reducing the need for constant monitoring by the central unit.
- The transformation of local diagnosis codes into global diagnosis codes allows for a comprehensive analysis of the control system's performance.
Benefits of this technology:
- Improved reliability and safety of the process engineering plant by detecting and addressing control system issues promptly.
- Enhanced efficiency and optimization of the process through accurate diagnosis and control.
- Cost savings by minimizing downtime and preventing major failures or breakdowns.
Original Abstract Submitted
in a method for diagnosing control system of a process engineering plant having a plurality of actuating units for setting a process fluid and a central unit, at least one actuating-unit-specific control raw datum, such as a setpoint value, an actual value, a setpoint-actual difference value, or a control value, is detected; a particularly local diagnosis code is generated by one of the plurality of actuating units based on the at least one detected control raw datum; the diagnosis code is transmitted from the actuating unit to a central unit; a local diagnosis code, is transformed into a global diagnosis codes; a logical condition for a diagnosis deduction logic is defined such that when the logical condition is applied to at least one diagnosis code, the diagnosis deduction logic determines a predetermined deduction result; and a deduction result is determined based on the at least one diagnosis code.
