Solution Overview

Problem

The complexity of process engineering relationships in technical plants, particularly those with modular structures, poses challenges for operators in efficiently and flexibly monitoring and operating these systems, often requiring detailed and up-to-date documentation that is not always readily available.

Innovation Solution

A control system and method that allows operators to define instructions and conditions for system interactions, which are stored and automatically checked, enabling flexible and efficient operation by providing guided documentation and notifications based on the plant's configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If operators manually check multiple process objects and documentation to handle alarms, then comprehensive monitoring is achieved, but operation time and efficiency deteriorate

Engineering Contradiction:
Improvealarm handling completenessVSAvoidoperator response time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system enables self-service by automatically generating notifications and guiding operators through predefined instructions when alarm conditions occur, eliminating the need for operators to manually search through documentation and process objects, thus reducing response time while maintaining comprehensive monitoring

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system prepares operator instructions and documentation in advance by storing them in the database associated with specific alarm conditions, so that when an alarm occurs, operators immediately receive pre-prepared guidance rather than searching for information during the incident

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If detailed documentation is made available to operators, then operational accuracy is improved, but system complexity and information management burden increase

Engineering Contradiction:
Improveoperational accuracyVSAvoiddocumentation management complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system extracts only the necessary documentation and instructions related to specific alarm conditions from the overall system documentation, presenting them to operators in a targeted manner rather than requiring access to complete documentation sets, thereby improving accuracy without overwhelming complexity

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The server acts as an intermediary between the documentation database and operators, automatically retrieving and presenting only the relevant instructions and documentation needed for specific alarm conditions, shielding operators from the complexity of managing comprehensive documentation while ensuring accurate information delivery

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the system supports modular plant structures with dynamic reconfiguration, then flexibility is improved, but system complexity and operator training requirements increase

Engineering Contradiction:
Improveplant reconfiguration flexibilityVSAvoidsystem configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The notification system is designed with universal functionality to handle various alarm conditions and plant configurations through a unified interface and standardized instruction formats, allowing the system to adapt to modular plant structures and dynamic reconfigurations without requiring complex specialized procedures for each scenario

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A control system (60) according to the invention for a technical plant, in particular a manufacturing or process plant, comprises at least one Operator Station Server (62) and at least one Operator Station Client (61) connected to the Operator Station Server, wherein the Operator Station Server (62) is configured to transmit visualization information to the Operator Station Client (61), and wherein the Operator Station Client (61) is configured to generate a graphical presentation (1) for an operator of the technical plant using the visualization information.The Operator Station Client (2) is configured to receive, during plant operation, an instruction (A1) specified by the operator for an operator activity related to the plant and a condition (AP1) specified by the operator, relating to an internal state of the plant, for the instruction (A), and to transmit them to the Operator Station Server (62). The Operator Station Server (62) is configured to store the instruction (A1) and condition (AP1) received from the Operator Station Client (61) in a memory (72) and to check whether the condition is met. This allows operators to adapt flexibly and efficiently to the operation and monitoring of a plant, especially if it is modularly designed for configurations that change during its lifecycle.
