Dynamic Standby Switching Sequences for Industrial Production Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for managing energy-saving standby states in industrial production systems are inefficient due to manual creation and maintenance of system circuit models, requiring significant effort and data management, and lack automated generation of switching sequences that adapt to changing system conditions.
Innovation Solution
A method that uses a dynamically changing predicate logic semantic plant model to automatically generate switching sequences by deriving relevant variables and action schemes from component relationships, reducing the need for manual intervention and enabling adaptive switching path determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual creation and maintenance of system circuit models is used, then system switching paths can be determined, but significant effort and data management are required
Solution Approach 1:
The system automatically generates switching sequences by having the control device query component information and autonomously determine switching paths without requiring manual model creation or maintenance by operators
Solution Approach 2:
The patent replaces manual mechanical processes of creating and maintaining circuit models with automated electronic querying and processing of component information through a control device
2Adaptability or versatility
If static switching paths are predetermined, then switching sequences can be executed, but they cannot adapt to changing system conditions
Solution Approach 1:
The system dynamically determines switching paths by querying current component information and states at runtime, allowing the switching sequences to adapt to changing system conditions rather than following static predetermined paths
Solution Approach 2:
The control device queries component information and uses the returned data to dynamically adjust switching paths, creating a feedback loop that enables adaptation to current system conditions
3Ease of operation
If detailed system models are maintained manually, then precise switching control is achieved, but operational complexity increases
Solution Approach 1:
Components provide their own information when queried by the control device, eliminating the need for manual model maintenance while ensuring accurate system state tracking through automated information collection

AI summary
The invention relates to the automated, dynamic and model-based generation and execution of switching sequences for standby-states in complex systems. It can be required to temporarily switch production systems, in whole or in part, into a standby state for energy saving. Production systems consist of a plurality of different components, which can optionally be combined to form aggregates and consequently be dependent on one another. Therefore, the following applies: "standby" represents a device state in which at least one function, but not the main function, is performed, wherein a significantly reduced energy consumption is achieved and the main function can be reactivated without pre-conditions at any time. The activating and exiting of standby states is however not immediately possible, rather a certain lead time is required. The object of the invention is to provide a method for the automated generation of a switching sequence, which permits the coordinated switching of the entire system into a standby state.
